From 55176907d2573e52ade4fc197fe7dff69ebd23a8 Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Tue, 10 Jan 2017 23:30:13 +0100 Subject: [PATCH 001/812] mingw: respect core.hidedotfiles = false in git-init again This is a brown paper bag. When adding the tests, we actually failed to verify that the config variable is heeded in git-init at all. And when changing the original patch that marked the .git/ directory as hidden after reading the config, it was lost on this developer that the new code would use the hide_dotfiles variable before the config was read. The fix is obvious: read the (limited, pre-init) config *before* creating the .git/ directory.

It comes in handy when resetting many, many paths at once and wildcards are not an option (e.g. when the paths are generated by a tool). Note: we first parse the entire list and perform the actual reset action only in a second phase. Not only does this make things simpler, it also helps performance, as do_diff_cache() traverses the index and the (sorted) pathspecs in simultaneously to avoid unnecessary lookups. This feature is marked experimental because it is still under review in the upstream Git project.

Maybe git-am is broken? This was due to lookup_prog not being Unicode-aware. It was somehow missed in 2ee5a1a14ad17ff35f0ad52390a27fbbc41258f3. Note that the only problem in this function was calling GetFileAttributes instead of GetFileAttributesW. The calls to access() were fine because access() is a macro which resolves to mingw_access, which already handles Unicode correctly.

Unfortunately this breaks pushing over the dump git protocol if used over a network connection. The detailed reasons for this breakage are (by courtesy of Jeff Preshing, quoted from ttps://groups.google.com/d/msg/msysgit/at8D7J-h7mw/eaLujILGUWoJ): ---------------------------------------------------------------------------- MinGW wraps Windows sockets in CRT file descriptors in order to mimic the functionality of POSIX sockets. This causes msvcrt.dll to treat sockets as Installable File System (IFS) handles, calling ReadFile, WriteFile, DuplicateHandle and CloseHandle on them. This approach works well in simple cases on recent versions of Windows, but does not support all usage patterns. In particular, using this approach, any attempt to read & write concurrently on the same socket (from one or more processes) will deadlock in a scenario where the read waits for a response from the server which is only invoked after the write. This is what send_pack currently attempts to do in the use_sideband codepath. ---------------------------------------------------------------------------- The new config option "sendpack.sideband" allows to override the side-band-64k capability of the server, and thus makes the dump git protocol work. Other transportation methods like ssh and http/https still benefit from the sideband channel, therefore the default value of "sendpack.sideband" is still true.

This applies to both 32bit and 64bit builds and makes it substantially harder to exploit security holes in Git by offering a much more unpredictable attack surface. ASLR interferes with GDB's ability to set breakpoints. A similar issue holds true when compiling with -O2 (in which case single-stepping is messed up because GDB cannot map the code back to the original source code properly). Therefore we simply enable ASLR only when an optimization flag is present in the CFLAGS, using it as an indicator that the developer does not want to debug in GDB anyway.

In other words, the return value is either 0 or points just after the dir separator. This assumption is not fulfilled when calling offset_1st_component() e.g. on UNC paths on Windows, e.g. "//my-server/my-share". In this case, offset_1st_component() returns the length of the entire string (which is correct, because stripping the last "component" would not result in a valid directory), yet the return value still does not point just after a dir separator. This assumption is most prominently seen in the setup_git_directory_gently_1() function, where we want to append a ".git" component and simply assume that there is already a dir separator. In the UNC example given above, this assumption is incorrect. As a consequence, Git will fail to handle a worktree at the top of a UNC share correctly. Let's fix this by adding a dir separator specifically for that case: we found that there is no first component in the path and it does not end in a dir separator? Then add it.

This is different from Unix and standard Windows directories: both / and C:\ are reported with a trailing slash as current directories. If a Git worktree is located there, Git is not quite prepared for that: while it does manage to find the .git directory/file, it returns as length of the top-level directory's path *one more* than the length of the current directory, and setup_git_directory_gently() would then return an undefined string as prefix. In practice, this undefined string usually points to NUL bytes, and does not cause much harm. Under rare circumstances that are really involved to reproduce (and not reliably so), the reported prefix could be a suffix string of Git's exec path, though. A careful analysis determined that this bug is unlikely to be exploitable, therefore we mark this as a regular bug fix.

Earlier, we made sure that the packs are released just before `git gc` is spawned, in case that gc wants to remove no-longer needed packs. But this developer forgot that gc itself also needs to let go of packs, e.g. when consolidating all packs via the --aggressive option. Likewise, `git repack -d` wants to delete obsolete packs and therefore needs to close all pack handles, too.

Those Unix shell quoting rules differ from the quoting rules applying to Windows' cmd and Powershell, making it a little awkward to quote command-line parameters properly when spawning other processes. In particular, git.exe passes arguments to subprocesses that are *not* intended to be interpreted as wildcards, and if they contain backslashes, those are not to be interpreted as escape characters, e.g. when passing Windows paths. Note: this is only a problem when calling MSYS2 executables, not when calling MINGW executables such as git.exe. However, we do call MSYS2 executables frequently, most notably when setting the use_shell flag in the child_process structure. There is no elegant way to determine whether the .exe file to be executed is an MSYS2 program or a MINGW one. But since the use case of passing a command line through the shell is so prevalent, we need to work around this issue at least when executing sh.exe. Let's introduce an ugly, hard-coded test whether argv[0] is "sh", and whether it refers to the MSYS2 Bash, to determine whether we need to quote the arguments differently than usual. That still does not fix the issue completely, but at least it is something. Incidentally, this also fixes the problem where `git clone \\server\repo` failed due to incorrect handling of the backslashes when handing the path to the git-upload-pack process. We need to take care to quote not only whitespace, but also curly brackets. As aliases frequently go through the MSYS2 Bash, and as aliases frequently get parameters such as HEAD@{yesterday}, let's make sure that this does not regress by adding a test case for that.

These files contain information about the time spent. So we need a way to measure time. While we could use `date +%s` for that, this will give us only seconds, i.e. very coarse-grained timings. GNU `date` supports `date +%s.%N` (i.e. nanosecond-precision output), but there is no equivalent in BSD `date` (read: on macOS, we would not be able to obtain precise timings). So let's introduce `test-tool date getnanos`, with an optional start time, that outputs preciser values. Granted, it is a bit pointless to try measuring times accurately in shell scripts, certainly to nanosecond precision. But it is better than second-granularity.

To make things a bit easier to understand, we refrain from using the `matrix` feature here because (while it is powerful) it can be a bit confusing to users who are not familiar with CI setups. Therefore, we use a separate phase even for similar configurations (such as GCC vs Clang on Linux, GCC vs Clang on macOS). Also, we make use of the shiny new feature we just introduced where the test suite can output JUnit-style .xml files. This information is made available in a nice UI that allows the viewer to filter by phase and/or test number, and to see trends such as: number of (failing) tests, time spent running the test suite, etc. Signed-off-by: Johannes Schindelin --- azure-pipelines.yml | 325 ++++++++++++++++++++++++++++++++++++++++++ ci/mount-fileshare.sh | 26 ++++ 2 files changed, 351 insertions(+) create mode 100644 azure-pipelines.yml create mode 100755 ci/mount-fileshare.sh diff --git a/azure-pipelines.yml b/azure-pipelines.yml new file mode 100644 index 0000000000..4dc6fea129 --- /dev/null +++ b/azure-pipelines.yml @@ -0,0 +1,325 @@ +resources: +- repo: self + fetchDepth: 1 + +phases: +- phase: linux_clang + displayName: linux-clang + condition: succeeded() + queue: + name: Hosted Ubuntu 1604 + steps: + -

So far, we do this "manually". However, in the next few commits we want to teach the test suite to optionally re-run scripts with different options, therefore we will have to have a consistent way to stop daemons. Let's introduce `test_atexit`, which is loosely modeled after `test_when_finished` (but has a broader scope: rather than running the commands after the current test case, run them when the test script finishes, and also run them when the `--immediate` option is in effect).

For test failures, this usually means that you want to see the detailed trace of the failing tests. With Travis CI, we passed the `--verbose-log` option to get those traces. However, that seems excessive, as we do not need/use the logs in almost all of those cases: only when a test fails do we have a way to include the trace. So let's do something different when using Azure DevOps: let's run all the tests with `--quiet` first, and only if a failure is encountered, try to trace the commands as they are executed. Of course, we cannot turn on `--verbose-log` after the fact. So let's just re-run the test with all the same options, adding `--verbose-log`. And then munging the output file into the JUnit XML on the fly. Note: there is an off chance that re-running the test in verbose mode "fixes" the failures (and this does happen from time to time!). That is a possibility we should be able to live with. Ideally, we would label this as "Passed upon rerun", and Azure Pipelines even know about that outcome, but it is not available when using the JUnit XML format for now: https://github.com/Microsoft/azure-pipelines-agent/blob/master/src/Agent.Worker/TestResults/JunitResultReader.cs Signed-off-by: Johannes Schindelin --- t/test-lib.sh | 34 +++++++++++++++++++++++++++++++++- 1 file changed, 33 insertions(+), 1 deletion(-) diff --git a/t/test-lib.sh b/t/test-lib.sh index e1e53c2e1a..3304620ad9 100644 --- a/t/test-lib.sh +++ b/t/test-lib.sh @@ -85,6 +85,13 @@ done,*) test "$(cat "$BASE.exit")" = 0 exit ;; +*' --write-junit-xml '*) + # record how to call this script *with* --verbose-log, in case + # we encounter a breakage + junit_rerun_options_sq="$(printf '%s\n' "$0" --verbose-log -x "$@" | + sed -e "s/'/'\\\\''/g" -e "s/^/'/" -e "s/\$/'/" | + tr '\012' ' ')" + ;; esac # For repeatability, reset the environment to known value. @@ -479,10 +486,31 @@ test_ok_ () { test_failure_ () { if test -n "$write_junit_xml" then + if test -z "$GIT_TEST_TEE_OUTPUT_FILE" + then + # clean up + test_atexit_handler + + # re-run with --verbose-log + echo "# Re-running: $junit_rerun_options_sq" >&2 + + cd "$TEST_DIRECTORY" && + eval "${TEST_SHELL_PATH}" "$junit_rerun_options_sq" \ + >/dev/null 2>&1 + status=$? + + say_color "" "$(test 0 = $status || + echo "not ")ok $test_count - (re-ran with trace)" + say "1..$test_count" + GIT_EXIT_OK=t + exit $status + fi + junit_insert="" junit_insert="$junit_insert $(xml_attr_encode \ - "$(printf '%s\n' "$@" | sed 1d)")" + "$(cat "$GIT_TEST_TEE_OUTPUT_FILE")")" + >"$GIT_TEST_TEE_OUTPUT_FILE" junit_insert="$junit_insert" write_junit_xml_testcase "$1" " $junit_insert" fi @@ -767,6 +795,10 @@ test_start_ () { if test -n "$write_junit_xml" then junit_start=$(test-tool date getnanos) + + # truncate output + test -z "$GIT_TEST_TEE_OUTPUT_FILE" || + >"$GIT_TEST_TEE_OUTPUT_FILE" fi } From 13b6a12ace9c1200e22cb19718554b584929bbfd Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Fri, 31 Aug 2018 16:26:32 +0200 Subject: [PATCH 043/812] tests: record more stderr with --write-junit-xml in case of failure Sometimes, failures in a test case are actually caused by issues in earlier test cases.

In the bin-wrappers/* scripts, we already take pains to use `git.exe` rather than `git`, as this could pick up the wrong thing on Windows (i.e. if there exists a `git` file or directory in the build directory). Now we do the same in the tests' start-up code. This also helps when testing an installed Git, as there might be even more likely some stray file or directory in the way. Note: the only way we can record whether the `.exe` suffix is by writing it to the `GIT-BUILD-OPTIONS` file and sourcing it at the beginning of `t/test-lib.sh`. This is not a requirement introduced by this patch, but we move the call to be able to use the `$X` variable that holds the file extension, if any. Note also: the many, many calls to `git this` and `git that` are unaffected, as the regular PATH search will find the `.exe` files on Windows (and not be confused by a directory of the name `git` that is in one of the directories listed in the `PATH` variable), while `/path/to/git` would not, per se, know that it is looking for an executable and happily prefer such a directory. For the same reason, we need to handle test-tool.exe the same way.

Work around this by just cutting off the command line at that length (actually, at a space boundary) in the hope that only negative refs are chucked: gitk will then do unnecessary work, but that is still better than flashing the gitk window and exiting with exit status 5 (which no Windows user is able to make sense of). The first fix caused Tcl to fail to compile the regexp, see msysGit issue 427. Here is another fix without using regexp, and using a more relaxed command line length limit to fix the original issue 387.

Earlier, libgit2 was nice enough to just re-use Git for Windows' C:\Program Files (x86)\Git\etc\gitconfig but with the upcoming Git for Windows 2.x, there would be more paths to search, as we will have 64-bit and 32-bit versions, and the corresponding config files will be in %PROGRAMFILES%\Git\mingw64\etc and ...\mingw32\etc, respectively. Worse: there are portable Git for Windows versions out there which live in totally unrelated directories, still. Therefore we came to a consensus to use `%PROGRAMDATA%\Git\config` as the location for shared Git settings that are of wider interest than just Git for Windows. Of course, the configuration in `%PROGRAMDATA%\Git\config` has the widest reach, therefore it must take the lowest precedence, i.e. Git for Windows can still override settings in its `etc/gitconfig` file.

Git for Windows introduced the `--no-lock-index` option a long time ago to fix that (it made it into Git for Windows v2.9.2(3)) by simply avoiding to write that file. The downside is that the periodic `git status` calls will be a little bit more wasteful because they may have to refresh the index repeatedly, only to throw away the updates when it exits. This cannot really be helped, though, as tools wanting to get a periodic update of the status have no way to predict when the user may want to lock the index herself. Sadly, a competing approach was submitted (by somebody who apparently has less work on their plate than this maintainer) that made it into v2.15.0 but is *different*: instead of a `git status`-only option, it is an option that comes *before* the Git command and is called differently, too. Let's give previous users a chance to upgrade to newer Git for Windows versions by handling the `--no-lock-index` option, still, though with a big fat warning.

Even if this value is not documented anywhere, CreateProcess() seems to work fine without complaints if hStdInput set to this value. In contrast, the upcoming code to restrict which file handles get inherited by spawned processes would result in `ERROR_INVALID_PARAMETER` when including such handle values in the list.

If you have an open-source +mindset and want to start contributing to Git, but primarily use a Windows machine, then you may +have trouble getting started. This guide is for you. + +Get the Source +-------------- + +Clone the [GitForWindows repository on GitHub](https://github.com/git-for-windows/git). +It is helpful to create your own fork for storing your development branches. + +Windows uses different line endings than Unix systems. See +[this GitHub article on working with line endings](https://help.github.com/articles/dealing-with-line-endings/#refreshing-a-repository-after-changing-line-endings) +if you have trouble with line endings. + +Build the Source +---------------- + +First, download and install the latest [Git for Windows SDK (64-bit)](https://github.com/git-for-windows/build-extra/releases/latest). +When complete, you can run the Git SDK, which creates a new Git Bash terminal window with +the additional development commands, such as `make`. + + As of time of writing, the SDK uses a different credential manager, so you may still want to use normal Git + Bash for interacting with your remotes. Alternatively, use SSH rather than HTTPS and + avoid credential manager problems. + +You should now be ready to type `make` from the root of your `git` source directory. +Here are some helpful variations: + +* `make -j[N] DEVELOPER=1`: Compile new sources using up to N concurrent processes. + The `DEVELOPER` flag turns on all warnings; code failing these warnings will not be + accepted upstream ("upstream" = "the core Git project"). +* `make clean`: Delete all compiled files. + +When running `make`, you can use `-j$(nproc)` to automatically use the number of processors +on your machine as the number of concurrent build processes. + +You can go deeper on the Windows-specific build process by reading the +[technical overview](https://github.com/git-for-windows/git/wiki/Technical-overview) or the +[guide to compiling Git with Visual Studio](https://github.com/git-for-windows/git/wiki/Compiling-Git-with-Visual-Studio). + +## Building `git` on Windows with Visual Studio + +The typical approach to building `git` is to use the standard `Makefile` with GCC, as +above. Developers working in a Windows environment may want to instead build with the +[Microsoft Visual C++ compiler and libraries toolset (MSVC)](https://blogs.msdn.microsoft.com/vcblog/2017/03/07/msvc-the-best-choice-for-windows/). +There are a few benefits to using MSVC over GCC during your development, including creating +symbols for debugging and [performance tracing](https://github.com/Microsoft/perfview#perfview-overview). + +There are two ways to build Git for Windows using MSVC. Each have their own merits. + +### Using SDK Command Line + +Use one of the following commands from the SDK Bash window to build Git for Windows: + +``` + make MSVC=1 -j12 + make MSVC=1 DEBUG=1 -j12 +``` + +The first form produces release-mode binaries; the second produces debug-mode binaries. +Both forms produce PDB files and can be debugged. However, the first is best for perf +tracing and the second is best for single-stepping. + +You can then open Visual Studio and select File -> Open -> Project/Solution and select +the compiled `git.exe` file. This creates a basic solution and you can use the debugging +and performance tracing tools in Visual Studio to monitor a Git process. Use the Debug +Properties page to set the working directory and command line arguments. + +Be sure to clean up before switching back to GCC (or to switch between debug and +release MSVC builds): + +``` + make MSVC=1 -j12 clean + make MSVC=1 DEBUG=1 -j12 clean +``` + +### Using `vs/master` Solution + +If you prefer working in Visual Studio with a solution full of projects, then there is a +branch in Git for Windows called [`vs/master`](https://github.com/git-for-windows/git/branches). +This branch is kept up-to-date with the `master` branch, except it has one more commit that +contains the solution and project files. Read [the wiki page on this approach](https://github.com/git-for-windows/git/wiki/Compiling-Git-with-Visual-Studio) for more information. + +I want to make a small warning before you start working on the `vs/master` branch. If you +create a new topic branch based on `vs/master`, you will need to rebase onto `master` before +you can submit a pull request. The commit at the tip of `vs/master` is not intended to ever +become part of the `master` branch. If you created a branch, `myTopic` based on `vs/master`, +then use the following rebase command to move it onto the `master` branch: + +``` +git rebase --onto master vs/master myTopic +``` + +What to Change? +--------------- + +Many new contributors ask: What should I start working on? + +One way to win big with the open-source community is to look at the +[issues page](https://github.com/git-for-windows/git/issues) and see if there are any issues that +you can fix quickly, or if anything catches your eye. + +You can also look at [the unofficial Chromium issues page](https://crbug.com/git) for +multi-platform issues. You can look at recent user questions on +[the Git mailing list](https://public-inbox.org/git). + +Or you can "scratch your own itch", i.e. address an issue you have with Git. The team at Microsoft where the Git for Windows maintainer works, for example, is focused almost entirely on [improving performance](https://blogs.msdn.microsoft.com/devops/2018/01/11/microsofts-performance-contributions-to-git-in-2017/). +We approach our work by finding something that is slow and try to speed it up. We start our +investigation by reliably reproducing the slow behavior, then running that example using +the MSVC build and tracing the results in PerfView. + +You could also think of something you wish Git could do, and make it do that thing! The +only concern I would have with this approach is whether or not that feature is something +the community also wants. If this excites you though, go for it! Don't be afraid to +[get involved in the mailing list](http://vger.kernel.org/vger-lists.html#git) early for +feedback on the idea. + +Test Your Changes +----------------- + +After you make your changes, it is important that you test your changes. Manual testing is +important, but checking and extending the existing test suite is even more important. You +want to run the functional tests to see if you broke something else during your change, and +you want to extend the functional tests to be sure no one breaks your feature in the future. + +### Functional Tests + +Navigate to the `t/` directory and type `make` to run all tests or use `prove` as +[described in the Git for Windows wiki](https://github.com/git-for-windows/git/wiki/Building-Git): + +``` +prove -j12 --state=failed,save ./t[0-9]*.sh +``` + +You can also run each test directly by running the corresponding shell script with a name +like `tNNNN-descriptor.sh`. + +If you are adding new functionality, you may need to create unit tests by creating +helper commands that test a very limited action. These commands are stored in `t/helpers`. +When adding a helper, be sure to add a line to `t/Makefile` and to the `.gitignore` for the +binary file you add. The Git community prefers functional tests using the full `git` +executable, so try to exercise your new code using `git` commands before creating a test +helper. + +To find out why a test failed, repeat the test with the `-x -v -d -i` options and then +navigate to the appropriate "trash" directory to see the data shape that was used for the +test failed step. + +Read [`t/README`](t/README) for more details. + +### Performance Tests + +If you are working on improving performance, you will need to be acquainted with the +performance tests in `t/perf`. There are not too many performance tests yet, but adding one +as your first commit in a patch series helps to communicate the boost your change provides. + +To check the change in performance across multiple versions of `git`, you can use the +`t/perf/run` script. For example, to compare the performance of `git rev-list` across the +`core/master` and `core/next` branches compared to a `topic` branch, you can run + +``` +cd t/perf +./run core/master core/next topic -- p0001-rev-list.sh +``` + +You can also set certain environment variables to help test the performance on different +repositories or with more repetitions. The full list is available in +[the `t/perf/README` file](t/perf/README), +but here are a few important ones: + +``` +GIT_PERF_REPO=/path/to/repo +GIT_PERF_LARGE_REPO=/path/to/large/repo +GIT_PERF_REPEAT_COUNT=10 +``` + +When running the performance tests on Linux, you may see a message "Can't locate JSON.pm in +@INC" and that means you need to run `sudo cpanm install JSON` to get the JSON perl package. + +For running performance tests, it can be helpful to set up a few repositories with strange +data shapes, such as: + +**Many objects:** Clone repos such as [Kotlin](https://github.com/jetbrains/kotlin), [Linux](https://github.com/torvalds/linux), or [Android](https://source.android.com/setup/downloading). + +**Many pack-files:** You can split a fresh clone into multiple pack-files of size at most +16MB by running `git repack -adfF --max-pack-size=16m`. See the +[`git repack` documentation](https://git-scm.com/docs/git-repack) for more information. +You can count the number of pack-files using `ls .git/objects/pack/*.pack | wc -l`. + +**Many loose objects:** If you already split your repository into multiple pack-files, then +you can pick one to split into loose objects using `cat .git/objects/pack/[id].pack | git unpack-objects`; +delete the `[id].pack` and `[id].idx` files after this. You can count the number of loose +bjects using `ls .git/objects/??/* | wc -l`. + +**Deep history:** Usually large repositories also have deep histories, but you can use the +[test-many-commits-1m repo](https://github.com/cirosantilli/test-many-commits-1m/) to +target deep histories without the overhead of many objects. One issue with this repository: +there are no merge commits, so you will need to use a different repository to test a "wide" +commit history. + +**Large Index:** You can generate a large index and repo by using the scripts in +`t/perf/repos`. There are two scripts. `many-files.sh` which will generate a repo with +same tree and blobs but different paths. Using `many-files.sh -d 5 -w 10 -f 9` will create +a repo with ~1 million entries in the index. `inflate-repo.sh` will use an existing repo +and copy the current work tree until it is a specified size. + +Test Your Changes on Linux +-------------------------- + +It can be important to work directly on the [core Git codebase](https://github.com/git/git), +such as a recent commit into the `master` or `next` branch that has not been incorporated +into Git for Windows. Also, it can help to run functional and performance tests on your +code in Linux before submitting patches to the mailing list, which focuses on many platforms. +The differences between Windows and Linux are usually enough to catch most cross-platform +issues. + +### Using the Windows Subsystem for Linux + +The [Windows Subsystem for Linux (WSL)](https://docs.microsoft.com/en-us/windows/wsl/install-win10) +allows you to [install Ubuntu Linux as an app](https://www.microsoft.com/en-us/store/p/ubuntu/9nblggh4msv6) +that can run Linux executables on top of the Windows kernel. Internally, +Linux syscalls are interpreted by the WSL, everything else is plain Ubuntu. + +First, open WSL (either type "Bash" in Cortana, or execute "bash.exe" in a CMD window). +Then install the prerequisites, and `git` for the initial clone: + +``` +sudo apt-get update +sudo apt-get install git gcc make libssl-dev libcurl4-openssl-dev \ + libexpat-dev tcl tk gettext git-email zlib1g-dev +``` + +Then, clone and build: + +``` +git clone https://github.com/git-for-windows/git +cd git +git remote add -f upstream https://github.com/git/git +make +``` + +Be sure to clone into `/home/[user]/` and not into any folder under `/mnt/?/` or your build +will fail due to colons in file names. + +### Using a Linux Virtual Machine with Hyper-V + +If you prefer, you can use a virtual machine (VM) to run Linux and test your changes in the +full environment. The test suite runs a lot faster on Linux than on Windows or with the WSL. +You can connect to the VM using an SSH terminal like +[PuTTY](https://www.chiark.greenend.org.uk/~sgtatham/putty/). + +The following instructions are for using Hyper-V, which is available in some versions of Windows. +There are many virtual machine alternatives available, if you do not have such a version installed. + +* [Download an Ubuntu Server ISO](https://www.ubuntu.com/download/server). +* Open [Hyper-V Manager](https://docs.microsoft.com/en-us/virtualization/hyper-v-on-windows/quick-start/enable-hyper-v). +* [Set up a virtual switch](https://docs.microsoft.com/en-us/virtualization/hyper-v-on-windows/quick-start/connect-to-network) + so your VM can reach the network. +* Select "Quick Create", name your machine, select the ISO as installation source, and un-check + "This virtual machine will run Windows." +* Go through the Ubuntu install process, being sure to select to install OpenSSH Server. +* When install is complete, log in and check the SSH server status with `sudo service ssh status`. + * If the service is not found, install with `sudo apt-get install openssh-server`. + * If the service is not running, then use `sudo service ssh start`. +* Use `shutdown -h now` to shutdown the VM, go to the Hyper-V settings for the VM, expand Network Adapter + to select "Advanced Features", and set the MAC address to be static (this can save your VM from losing + network if shut down incorrectly). +* Provide as many cores to your VM as you can (for parallel builds). +* Restart your VM, but do not connect. +* Use `ssh` in Git Bash, download [PuTTY](http://www.putty.org/), or use your favorite SSH client to connect to the VM through SSH. + +In order to build and use `git`, you will need the following libraries via `apt-get`: + +``` +sudo apt-get update +sudo apt-get install git gcc make libssl-dev libcurl4-openssl-dev \ + libexpat-dev tcl tk gettext git-email zlib1g-dev +``` + +To get your code from your Windows machine to the Linux VM, it is easiest to push the branch to your fork of Git and clone your fork in the Linux VM. + +Don't forget to set your `git` config with your preferred name, email, and editor. + +Polish Your Commits +------------------- + +Before submitting your patch, be sure to read the [coding guidelines](https://github.com/git/git/blob/master/Documentation/CodingGuidelines) +and check your code to match as best you can. This can be a lot of effort, but it saves +time during review to avoid style issues. + +The other possibly major difference between the mailing list submissions and GitHub PR workflows +is that each commit will be reviewed independently. Even if you are submitting a +patch series with multiple commits, each commit must stand on it's own and be reviewable +by itself. Make sure the commit message clearly explain the why of the commit not the how. +Describe what is wrong with the current code and how your changes have made the code better. + +When preparing your patch, it is important to put yourself in the shoes of the Git community. +Accepting a patch requires more justification than approving a pull request from someone on +your team. The community has a stable product and is responsible for keeping it stable. If +you introduce a bug, then they cannot count on you being around to fix it. When you decided +to start work on a new feature, they were not part of the design discussion and may not +even believe the feature is worth introducing. + +Questions to answer in your patch message (and commit messages) may include: +* Why is this patch necessary? +* How does the current behavior cause pain for users? +* What kinds of repositories are necessary for noticing a difference? +* What design options did you consider before writing this version? Do you have links to + code for those alternate designs? +* Is this a performance fix? Provide clear performance numbers for various well-known repos. + +Here are some other tips that we use when cleaning up our commits: + +* Commit messages should be wrapped at 76 columns per line (or less; 72 is also a + common choice). +* Make sure the commits are signed off using `git commit (-s|--signoff)`. See + [SubmittingPatches](https://github.com/git/git/blob/v2.8.1/Documentation/SubmittingPatches#L234-L286) + for more details about what this sign-off means. +* Check for whitespace errors using `git diff --check [base]...HEAD` or `git log --check`. +* Run `git rebase --whitespace=fix` to correct upstream issues with whitespace. +* Become familiar with interactive rebase (`git rebase -i`) because you will be reordering, + squashing, and editing commits as your patch or series of patches is reviewed. +* Make sure any shell scripts that you add have the executable bit set on them. This is + usually for test files that you add in the `/t` directory. You can use + `git add --chmod=+x [file]` to update it. You can test whether a file is marked as executable + using `git ls-files --stage \*.sh`; the first number is 100755 for executable files. +* Your commit titles should match the "area: change description" format. Rules of thumb: + * Choose "<area>: " prefix appropriately. + * Keep the description short and to the point. + * The word that follows the "<area>: " prefix is not capitalized. + * Do not include a full-stop at the end of the title. + * Read a few commit messages -- using `git log origin/master`, for instance -- to + become acquainted with the preferred commit message style. +* Build source using `make DEVELOPER=1` for extra-strict compiler warnings. + +Submit Your Patch +----------------- + +Git for Windows [accepts pull requests on GitHub](https://github.com/git-for-windows/git/pulls), but +these are reserved for Windows-specific improvements. For core Git, submissions are accepted on +[the Git mailing list](https://public-inbox.org/git). + +### Configure Git to Send Emails + +There are a bunch of options for configuring the `git send-email` command. These options can +be found in the documentation for +[`git config`](https://git-scm.com/docs/git-config) and +[`git send-email`](https://git-scm.com/docs/git-send-email). + +``` +git config --global sendemail.smtpserver <smtp server> +git config --global sendemail.smtpserverport 587 +git config --global sendemail.smtpencryption tls +git config --global sendemail.smtpuser <email address> +``` + +To avoid storing your password in the config file, store it in the Git credential manager: + +``` +$ git credential fill +protocol=smtp +host=<stmp server> +username=<email address> +password=password +``` + +Before submitting a patch, read the [Git documentation on submitting patches](https://github.com/git/git/blob/master/Documentation/SubmittingPatches). + +To construct a patch set, use the `git format-patch` command. There are three important options: + +* `--cover-letter`: If specified, create a `[v#-]0000-cover-letter.patch` file that can be + edited to describe the patch as a whole. If you previously added a branch description using + `git branch --edit-description`, you will end up with a 0/N mail with that description and + a nice overall diffstat. +* `--in-reply-to=[Message-ID]`: This will mark your cover letter as replying to the given + message (which should correspond to your previous iteration). To determine the correct Message-ID, + find the message you are replying to on [public-inbox.org/git](https://public-inbox.org/git) and take + the ID from between the angle brackets. + +* `--subject-prefix=[prefix]`: This defaults to [PATCH]. For subsequent iterations, you will want to + override it like `--subject-prefix="[PATCH v2]"`. You can also use the `-v` option to have it + automatically generate the version number in the patches. + +If you have multiple commits and use the `--cover-letter` option be sure to open the +`0000-cover-letter.patch` file to update the subject and add some details about the overall purpose +of the patch series. + +### Examples + +To generate a single commit patch file: +``` +git format-patch -s -o [dir] -1 +``` +To generate four patch files from the last three commits with a cover letter: +``` +git format-patch --cover-letter -s -o [dir] HEAD~4 +``` +To generate version 3 with four patch files from the last four commits with a cover letter: +``` +git format-patch --cover-letter -s -o [dir] -v 3 HEAD~4 +``` + +### Submit the Patch + +Run [`git send-email`](https://git-scm.com/docs/git-send-email), starting with a test email: + +``` +git send-email --to=yourself@address.com [dir with patches]/*.patch +``` + +After checking the receipt of your test email, you can send to the list and to any +potentially interested reviewers. + +``` +git send-email --to=git@vger.kernel.org --cc=<email1> --cc=<email2> [dir with patches]/*.patch +``` + +To submit a nth version patch (say version 3): + +``` +git send-email --to=git@vger.kernel.org --cc=<email1> --cc=<email2> \ + --in-reply-to=<the message id of cover letter of patch v2> [dir with patches]/*.patch +``` From 37778932107eb507a880faf4513cab2d9edd9e68 Mon Sep 17 00:00:00 2001 From: Johannes Schindelin <johannes.schindelin@gmx.de> Date: Fri, 10 Jan 2014 16:16:03 -0600 Subject: [PATCH 079/812] README.md: Add a Windows-specific preamble Includes touch-ups by Philip Oakley.

This is necessary because Git for Windows wants to use UTF-8 encoded strings throughout its code, and the main() function does not get the parameters in that encoding. To do that, we used the __wgetmainargs() function, which is not even a Win32 API function, but provided by the MINGW "runtime" instead. Obviously, this method would not work with any other compiler than GCC, and in preparation for compiling with Visual C++, we would like to avoid that. Lucky us, there is a much more elegant way: we simply implement wmain() and link with -municode. The command-line parameters are passed to wmain() encoded in UTF-16, as desired, and this method also works with Visual C++.

It is a perfectly legal way to define those constants, though, therefore we need to take care of defining O_ACCMODE accordingly. This is particularly important in order to keep our "open() can set errno to EISDIR" emulation working: it tests that (flags & O_ACCMODE) is not identical to O_RDONLY before going on to test specifically whether the file for which open() reported EACCES is, in fact, a directory.

See https://github.com/Microsoft/vcpkg On a first build, the vcpkg tools and the third party libraries are automatically downloaded and built. DLLs for the third party libraries are copied to the top-level (and t/helper) directory to facilitate debugging. See compat/vcbuild/README. A series of .bat files are invoked by the Makefile to find the location of the installed version of Visual Studio and the associated compiler tools (essentially replicating the environment setup performed by a "Developer Command Prompt"). This should find the most recent VS2015 or VS2017 installation. Output from these scripts are used by the Makefile to define compiler and linker pathnames and -I and -L arguments. The build produces .pdb files for both debug and release builds. Note: This commit was squashed from an organic series of commits developed between 2016 and 2018 in Git for Windows' `master` branch. This combined commit eliminates the obsolete commits related to fetching NuGet packages for third party libraries. It is difficult to use NuGet packages for C/C++ sources because they may be built by earlier versions of the MSVC compiler and have CRT version and linking issues. Additionally, the C/C++ NuGet packages that were using tended to not be updated concurrently with the sources. And in the case of cURL and OpenSSL, this could expose us to security issues.

However, when running the test suite, it is not so helpful, in particular when the debug assertions are then suppressed anyway because we disable the invalid parameter checking (via invalidcontinue.obj, see the comment in config.mak.uname about that object for more information). So let's simply disable that window in Debug Mode (it is already disabled in Release Mode).

Based on the generator for Visual Studio versions <= 2008 (which used .sln/.vcproj files), this patch copy-edits the generator of the .vcproj files to a new generator that produces .vcxproj files ready for Visual Studio 2010 and later (or MSBuild). As the vcpkg system (which is used to build Git's dependencies) cannot run in parallel (it does not lock, wreaking havoc with files being accessed and written at the same time, letting the vcpkg processes stumble over each others' toes), we make libgit the root of the project dependency tree and initialize the vcpkg system in this project's PreBuildEvent.

So let's just add a target in the Makefile that can be used to generate said solution; The generated files will then be committed so that they can be pushed to a branch ready to check out by Visual Studio users. To make things even more useful, we also generate and commit other files that are required to run the test suite, such as templates and bin-wrappers: with this, developers can run the test suite in a regular Git Bash (that is part of a regular Git for Windows installation) after building the solution in Visual Studio.

A more sophisticated implementation may cache this data, e.g. for later reuse in calls to lstat. Make the dirent implementation pluggable so that it can be switched at runtime, e.g. based on a config option. Define a base DIR structure with pointers to readdir/closedir that match the opendir implementation (i.e. similar to vtable pointers in OOP). Define readdir/closedir so that they call the function pointers in the DIR structure. This allows to choose the opendir implementation on a call-by-call basis. Move the fixed sized dirent.d_name buffer to the dirent-specific DIR structure, as d_name may be implementation specific (e.g. a caching implementation may just set d_name to point into the cache instead of copying the entire file name string).

Windows operating system APIs seem to be much better at scanning the status of entire directories than checking single files. Add an lstat implementation that uses a cache for lstat data. Cache misses read the entire parent directory and add it to the cache. Subsequent lstat calls for the same directory are served directly from the cache. Also implement opendir / readdir / closedir so that they create and use directory listings in the cache. The cache doesn't track file system changes and doesn't plug into any modifying file APIs, so it has to be explicitly enabled for git functions that don't modify the working copy. Note: in an earlier version of this patch, the cache was always active and tracked file system changes via ReadDirectoryChangesW. However, this was much more complex and had negative impact on the performance of modifying git commands such as 'git checkout'.

On cache miss, add a future object to the cache to indicate that the directory is currently being loaded. Subsequent threads register themselves with the future object and wait.

This limitation is also evident in Windows Explorer, cmd.exe and many other applications (including IDEs). Particularly annoying is that most Windows APIs return bogus error codes if a relative path only barely exceeds MAX_PATH in conjunction with the current directory, e.g. ERROR_PATH_NOT_FOUND / ENOENT instead of the infinitely more helpful ERROR_FILENAME_EXCED_RANGE / ENAMETOOLONG. Many Windows wide char APIs support longer than MAX_PATH paths through the file namespace prefix ('\\?\' or '\\?\UNC\') followed by an absolute path. Notable exceptions include functions dealing with executables and the current directory (CreateProcess, LoadLibrary, Get/SetCurrentDirectory) as well as the entire shell API (ShellExecute, SHGetSpecialFolderPath...). Introduce a handle_long_path function to check the length of a specified path properly (and fail with ENAMETOOLONG), and to optionally expand long paths using the '\\?\' file namespace prefix. Short paths will not be modified, so we don't need to worry about device names (NUL, CON, AUX). Contrary to MSDN docs, the GetFullPathNameW function doesn't seem to be limited to MAX_PATH (at least not on Win7), so we can use it to do the heavy lifting of the conversion (translate '/' to '\', eliminate '.' and '..', and make an absolute path). Add long path error checking to xutftowcs_path for APIs with hard MAX_PATH limit. Add a new MAX_LONG_PATH constant and xutftowcs_long_path function for APIs that support long paths. While improved error checking is always active, long paths support must be explicitly enabled via 'core.longpaths' option. This is to prevent end users to shoot themselves in the foot by checking out files that Windows Explorer, cmd/bash or their favorite IDE cannot handle. Test suite: Test the case is when the full pathname length of a dir is close to 260 (MAX_PATH).

With this patch, the bash will be executed through strace if the environment variable GIT_STRACE_COMMANDS is set, which comes in real handy when investigating issues in the test suite. Also support passing a path to a log file via GIT_STRACE_COMMANDS to force Git to call strace.exe with the `-o <path>` argument, i.e. to log into a file rather than print the log directly. That comes in handy when the output would otherwise misinterpreted by a calling process as part of Git's output. Note: the values "1", "yes" or "true" are *not* specifying paths, but tell Git to let strace.exe log directly to the console.

The first and more obvious behavior is "Installer Detection", where Windows sometimes decides (by looking at things like the file name and even sequences of bytes within the executable) that an executable is an installer and should run elevated (causing the well-known popup dialog to appear). In Git's context, subcommands such as "git patch-id" or "git update-index" fall prey to this behavior. The second and more confusing behavior is "File Virtualization". It means that when files are written without having write permission, it does not fail (as expected), but they are instead redirected to somewhere else. When the files are read, the original contents are returned, though, not the ones that were just written somewhere else. Even more confusing, not all write accesses are redirected; Trying to write to write-protected .exe files, for example, will fail instead of redirecting. In addition to being unwanted behavior, File Virtualization causes dramatic slowdowns in Git (see for instance http://code.google.com/p/msysgit/issues/detail?id=320). There are two ways to prevent those two behaviors: Either you embed an application manifest within all your executables, or you add an external manifest (a file with the same name followed by .manifest) to all your executables. Since Git's builtins are hardlinked (or copied), it is simpler and more robust to embed a manifest. A recent enough MSVC compiler should already embed a working internal manifest, but for MinGW you have to do so by hand.

Gettext uses setlocale() to determine the output encoding for translated text, however, MSVCRT's setlocale() doesn't support UTF-8. As a result, translated text is encoded in system encoding (GetAPC()), and non-ASCII chars are mangled in console output. Use gettext's bind_textdomain_codeset() to force the encoding to UTF-8 on native Windows. In this developers' setup, HAVE_LIBCHARSET_H is apparently defined, but we *really* want to override the locale_charset() here.

However, this is not the case with terminal windows other than `cmd.exe`'s, e.g. with MSys2's own `mintty`. Non-cmd terminals such as `mintty` still have to have a Win32 Console to be proper console programs, but have to hide the Win32 Console to be able to provide more flexibility (such as being resizeable not only vertically but also horizontally). By writing to that Win32 Console, `git_terminal_prompt()` manages only to send the prompt to nowhere and to wait for input from a Console to which the user has no access. This commit introduces a function specifically to support `mintty` -- or other terminals that are compatible with MSys2's `/dev/tty` emulation. We use the `TERM` environment variable as an indicator for that: if the value starts with "xterm" (such as `mintty`'s "xterm_256color"), we prefer to let `xterm_prompt()` handle the user interaction. The most prominent user of `git_terminal_prompt()` is certainly `git-remote-https.exe`. It is an interesting use case because both `stdin` and `stdout` are redirected when Git calls said executable, yet it still wants to access the terminal. When running inside a `mintty`, the terminal is not accessible to the `git-remote-https.exe` program, though, because it is a MinGW program and the `mintty` terminal is not backed by a Win32 console. To solve that problem, we simply call out to the shell -- which is an *MSys2* program and can therefore access `/dev/tty`.

It also doesn't work for terminal emulators that hide the native console window (such as mintty), and 'TERM=xterm*' is not necessarily a reliable indicator for such terminals. The new shell_prompt() function, on the other hand, works fine for both MSys1 and MSys2, in native console windows as well as mintty, and properly supports Unicode. It just needs bash on the path (for 'read -s', which is bash-specific). On Windows, try to use the shell to read from the terminal. If that fails with ENOENT (i.e. bash was not found), use CONIN/OUT as fallback. Note: To test this, create a UTF-8 credential file with non-ASCII chars, e.g. in git-bash: 'echo url=http://täst.com > cred.txt'. Then in git-cmd, 'git credential fill <cred.txt' works (shell version), while calling git without the git-wrapper (i.e. 'mingw64\bin\git credential fill <cred.txt') mangles non-ASCII chars in both console output and input.

But GPG might fail, and send error messages to stderr. And we simply do not show them to the user. Even worse: this swallows any interactive prompt for a passphrase. And detaches stderr from the tty so that the passphrase cannot be read. So while the first problem could be fixed (by printing the captured stderr upon error), the second problem cannot be easily fixed, and presents a major regression. So let's just revert commit efee9553a4f97b2ecd8f49be19606dd4cf7d9c28.

An unintended side-effect is that "cold-calling" into the POSIX emulation will start with a locale based on the current code page, something that Git for Windows is very ill-prepared for, as it expects to be able to pass a command-line containing non-ASCII characters to the shell without having those characters munged. One symptom of this behavior: when `git clone` or `git fetch` shell out to call `git-upload-pack` with a path that contains non-ASCII characters, the shell tried to interpret the entire command-line (including command-line parameters) as executable path, which obviously must fail.

Implement stat by opening the file with as little permissions as possible and calling GetFileInformationByHandle on it. This way, all link resoltion is handled by the Windows file system layer. If symlinks are disabled, use lstat() as before, but fail with ELOOP if a symlink would have to be resolved.

However, currently there is no error handling whatsoever if FindFirstFile() fails. Call FindFirstFile() before modifying the stat *buf output parameter and error out if the call fails. Note: The FindFirstFile() return value includes all the data that we get from GetFileAttributesEx(), so we could replace GetFileAttributesEx() with FindFirstFile(). We don't do that because GetFileAttributesEx() is about twice as fast for single files. I.e. we only pay the extra cost of calling FindFirstFile() in the rare case that we encounter a reparse point. Note: The indentation of the remaining reparse point code will be fixed in the next patch.

Symlinks of wrong type simply don't work. This even affects core Win32 APIs (e.g. DeleteFile() refuses to delete directory symlinks). However, CreateFile() with FILE_FLAG_BACKUP_SEMANTICS doesn't seem to care. Check the target type by first creating a tentative file symlink, opening it, and checking the type of the resulting handle. If it is a directory, recreate the symlink with the directory flag set. It is possible to create symlinks before the target exists (or in case of symlinks to symlinks: before the target type is known). If this happens, create a tentative file symlink and postpone the directory decision: keep a list of phantom symlinks to be processed whenever a new directory is created in mingw_mkdir(). Limitations: This algorithm may fail if a link target changes from file to directory or vice versa, or if the target directory is created in another process.

This new flag is called SYMBOLIC_LINK_FLAG_ALLOW_UNPRIVILEGED_CREATE and has the numeric value 0x02. Previous Windows 10 versions will not understand that flag and return an ERROR_INVALID_PARAMETER, therefore we have to be careful to try passing that flag only when the build number indicates that it is supported. For more information about the new flag, see this blog post: https://blogs.windows.com/buildingapps/2016/12/02/symlinks-windows-10/ This patch is loosely based on the patch submitted by Samuel D. Leslie as https://github.com/git-for-windows/git/pull/1184.

This is a performance optimization. FSCACHE is a performance optimization available for Windows. It intercepts Posix-style lstat() calls into an in-memory directory using FindFirst/FindNext. It improves performance on Windows by catching the first lstat() call in a directory, using FindFirst/ FindNext to read the list of files (and attribute data) for the entire directory into the cache, and short-cut subsequent lstat() calls in the same directory. This gives a major performance boost on Windows. However, it does not remember "not found" directories. When STATUS runs and there are missing directories, the lstat() interception fails to find the parent directory and simply return ENOENT for the file -- it does not remember that the FindFirst on the directory failed. Thus subsequent lstat() calls in the same directory, each re-attempt the FindFirst. This completely defeats any performance gains. This can be seen by doing a sparse-checkout on a large repo and then doing a read-tree to reset the skip-worktree bits and then running status. This change reduced status times for my very large repo by 60%.

This is not good, as Git for Windows relies on the core.longPaths setting to be read quite early on. So let's just make sure that all commands read the config and give platform_core_config() a chance. This patch teaches tons of Git commands to respect the config setting `core.longPaths = true`, including `pack-refs`, thereby fixing https://github.com/git-for-windows/git/issues/1218 Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> --- builtin/archive.c | 2 ++ builtin/bisect--helper.c | 2 ++ builtin/bundle.c | 2 ++ builtin/check-ref-format.c | 2 ++ builtin/clone.c | 1 + builtin/column.c | 2 ++ builtin/credential.c | 3 +++ builtin/fetch-pack.c | 2 ++ builtin/get-tar-commit-id.c | 2 ++ builtin/interpret-trailers.c | 2 ++ builtin/log.c | 1 + builtin/ls-remote.c | 2 ++ builtin/mailinfo.c | 2 ++ builtin/mailsplit.c | 2 ++ builtin/merge-index.c | 3 +++ builtin/merge-tree.c | 2 ++ builtin/mktag.c | 2 ++ builtin/mktree.c | 2 ++ builtin/pack-refs.c | 2 ++ builtin/prune-packed.c | 2 ++ builtin/prune.c | 3 +++ builtin/reflog.c | 1 + builtin/remote-ext.c | 2 ++ builtin/remote.c | 1 + builtin/rev-parse.c | 1 + builtin/show-index.c | 2 ++ builtin/show-ref.c | 2 ++ builtin/stripspace.c | 5 ++--- builtin/submodule--helper.c | 1 + builtin/upload-archive.c | 3 +++ credential-store.c | 3 +++ http-backend.c | 1 + refs.c | 2 +- 33 files changed, 63 insertions(+), 4 deletions(-) diff --git a/builtin/archive.c b/builtin/archive.c index d2455237ce..5c3f5a4678 100644 --- a/builtin/archive.c +++ b/builtin/archive.c @@ -9,6 +9,7 @@ #include "parse-options.h" #include "pkt-line.h" #include "sideband.h" +#include "config.h" static void create_output_file(const char *output_file) { @@ -94,6 +95,7 @@ int cmd_archive(int argc, const char **argv, const char *prefix) OPT_END() };

The current code in add_excludes() calls open() and then fstat() for a ".gitignore" file in each directory present in the worktree. Change that when fscache is enabled to call lstat() first and if present, call open(). This seems backwards because both lstat needs to do more work than fstat. But when fscache is enabled, fscache will already know if the .gitignore file exists and can completely avoid the IO calls. This works because of the lstat diversion to mingw_lstat when fscache is enabled. This reduced status times on a 350K file enlistment of the Windows repo on a NVMe SSD by 0.25 seconds.

During an "add", a call is made to run_diff_files() which calls check_remove() for each index-entry. This calls lstat(). On Windows, the fscache code intercepts the lstat() calls and builds a private cache using the FindFirst/FindNext routines, which are much faster. Somewhat independent of this, is the preload-index code which distributes some of the start-up costs across multiple threads. We need to keep the call to read_cache() before parsing the pathspecs (and hence cannot use the pathspecs to limit any preload) because parse_pathspec() is using the index to determine whether a pathspec is, in fact, in a submodule. If we would not read the index first, parse_pathspec() would not error out on a path that is inside a submodule, and t7400-submodule-basic.sh would fail with not ok 47 - do not add files from a submodule We still want the nice preload performance boost, though, so we simply call read_cache_preload(&pathspecs) after parsing the pathspecs.

Later when the ignore file was read, the buffer length did not match the stat.st_size field and we called die("cannot use <path> as an exclude file") Optimization Rationale ====================== The above optimization calls lstat() before open() primarily to ask fscache if the file exists. It gets the current stat-data as a side effect essentially for free (since we already have it in memory). If the file does not exist, it does not need to call open(). And since very few directories have .gitignore files, we can greatly reduce time spent in the filesystem. Discussion of Fix ================= The above optimization calls lstat() rather than stat() because the fscache only intercepts lstat() calls. Calls to stat() stay directed to the mingw_stat() completly bypassing fscache. Furthermore, calls to mingw_stat() always call {open, fstat, close} so that symlinks are properly dereferenced, which adds *additional* open/close calls on top of what the original code in dir.c is doing. Since the problem only manifests for symlinks, we add code to overwrite the stat-data when the path is a symlink. This preserves the effect of the performance gains provided by the fscache in the normal case.

This is bad insofar as Git itself expects its signal handlers to run. A symptom is e.g. a left-behind .lock file that would not be left behind if the same operation was run, say, on Linux. To remedy this situation, we use an obscure trick: we inject a thread into the process that needs to be killed and to let that thread run the ExitProcess() function with the desired exit status. Thanks J Wyman for describing this trick. The advantage is that the ExitProcess() function lets the atexit handlers run. While this is still different from what Git expects (i.e. running a signal handler), in practice Git sets up signal handlers and atexit handlers that call the same code to clean up after itself. In case that the gentle method to terminate the process failed, we still fall back to calling TerminateProcess(), but in that case we now also make sure that processes spawned by the spawned process are terminated; TerminateProcess() does not give the spawned process a chance to do so itself. Please note that this change only affects how Git for Windows tries to terminate processes spawned by Git's own executables. Third-party software that *calls* Git and wants to terminate it *still* need to make sure to imitate this gentle method, otherwise this patch will not have any effect.

This is a total waste of time and effort on a filesystem that orders data writes properly, but can be useful for filesystems that do not use journalling (traditional UNIX filesystems) or that only journal metadata and not file contents (OS X’s HFS+, or Linux ext3 with "data=writeback"). The most common file system on Windows (NTFS) does not guarantee that order, therefore a sudden loss of power (or any other event causing an unclean shutdown) would cause corrupt files (i.e. files filled with NULs). Therefore we need to change the default. Note that the documentation makes it sound as if this causes really bad performance. In reality, writing loose objects is something that is done only rarely, and only a handful of files at a time.

Which we do need to set because we need to pass in stdin/stdout/stderr to talk to the child processes. Sadly, this means that all file handles (unless marked via O_NOINHERIT) are inherited. This lead to problems in GVFS Git, where a long-running read-object hook is used to hydrate missing objects, and depending on the circumstances, might only be called *after* Git opened a file handle. Ideally, we would not open files without O_NOINHERIT unless *really* necessary (i.e. when we want to pass the opened file handle as standard handle into a child process), but apparently it is all-too-easy to introduce incorrect open() calls: this happened, and prevented updating a file after the read-object hook was started because the hook still held a handle on said file. Happily, there is a solution: as described in the "Old New Thing" https://blogs.msdn.microsoft.com/oldnewthing/20111216-00/?p=8873 there is a way, starting with Windows Vista, that lets us define precisely which handles should be inherited by the child process. And since we bumped the minimum Windows version for use with Git for Windows to Vista with v2.10.1 (i.e. a *long* time ago), we can use this method. So let's do exactly that. We need to make sure that the list of handles to inherit does not contain duplicates; Otherwise CreateProcessW() would fail with ERROR_INVALID_ARGUMENT. While at it, stop setting errno to ENOENT unless it really is the correct value. Also, fall back to not limiting handle inheritance under certain error conditions (e.g. on Windows 7, which is a lot stricter in what handles you can specify to limit to).

And similar to Git's builtins, the applets can be called via `busybox <command>`, or the BusyBox executable can be copied/hard-linked to the command name. The similarities do not end here. Just as with Git's builtins, it is problematic that BusyBox' hard-linked applets cannot easily be put into a .zip file: .zip archives have no concept of hard-links and therefore would store identical copies (and also extract identical copies, "inflating" the archive unnecessarily). To counteract that issue, MinGit already ships without hard-linked copies of the builtins, and the plan is to do the same with BusyBox' applets: simply ship busybox.exe as single executable, without hard-linked applets. To accommodate that, Git is being taught by this commit a very special trick, exploiting the fact that it is possible to call an executable with a command-line whose argv[0] is different from the executable's name: when `sh` is to be spawned, and no `sh` is found in the PATH, but busybox.exe is, use that executable (with unchanged argv). Likewise, if any executable to be spawned is not on the PATH, but busybox.exe is found, parse the output of `busybox.exe --help` to find out what applets are included, and if the command matches an included applet name, use busybox.exe to execute it.

This helps e.g. when trying to verify a Git for Windows installation without requiring to download a full Git for Windows SDK (which would use up 600+ megabytes of bandwidth, and over a gigabyte of disk space). Of course, it still requires the test helpers to be build *somewhere*, and the Git version should at least roughly match the version from which the test suite comes. At the same time, this new way to run the test suite allows to validate that a BusyBox-backed MinGit works as expected (verifying that BusyBox' functionality is enough to at least pass the test suite).

However, that limits esoteric test scenarios such as Git for Windows', where an end user installation has to ship with `iconv` for the sole purpose of being testable. That payload serves no other purpose. So let's just have a test helper (to be able to test Git, the test helpers have to be available, after all) to act as `iconv` replacement.

That also means that it does *not* use the Unix convention of separating the entries in the PATH variable using colons, but semicolons. However, there are also BusyBox ports to Windows which use a POSIX emulation layer such as Cygwin's or MSYS2's runtime, i.e. using colons as PATH separators. As a tell-tale, let's use the presence of semicolons in the PATH variable: on Unix, it is highly unlikely that it contains semicolons, and on Windows (without POSIX emulation), it is virtually guaranteed, as everybody should have both $SYSTEMROOT and $SYSTEMROOT/system32 in their PATH.

We already excluded test cases using such files from running on Windows when git.exe itself was tested. However, we still had two test cases that try to create such a file, and redirect stdin from such a file, respectively. This *seems* to work in Git for Windows' Bash due to an obscure feature inherited from Cygwin: illegal filename characters are simply mapped into/from a private UTF-8 page. Pure Win32 programs (such as git.exe) *still* cannot work with those files, of course, but at least Unix shell scripts pretend to be able to. This entire strategy breaks down when switching to any Unix shell lacking support for that private UTF-8 page trick, e.g. BusyBox-w32's ash.

There *are* some more native ports of Unix shells out there, though, most notably BusyBox-w32's ash. These native ports do not use any POSIX emulation layer (or at most a *very* thin one, choosing to avoid features such as fork() that are expensive to emulate on Windows), and they use native Windows paths (usually with forward slashes instead of backslashes, which is perfectly legal in almost all use cases). And here comes the problem: with a $PWD looking like, say, C:/git-sdk-64/usr/src/git/t/trash directory.t5813-proto-disable-ssh Git's test scripts get quite a bit confused, as their assumptions have been shattered. Not only does this path contain a colon (oh no!), it also does not start with a slash. This is a problem e.g. when constructing a URL as t5813 does it: ssh://remote$PWD. Not only is it impossible to separate the "host" from the path with a $PWD as above, even prefixing $PWD by a slash won't work, as /C:/git-sdk-64/... is not a valid path. As a workaround, detect when $PWD does not start with a slash on Windows, and simply strip the drive prefix, using an obscure feature of Windows paths: if an absolute Windows path starts with a slash, it is implicitly prefixed by the drive prefix of the current directory. As we are talking about the current directory here, anyway, that strategy works.

If we feed that path to CVS, it mistakes it for a separator between host and port, though. This has not been a problem so far because Git for Windows uses MSYS2's Bash using a POSIX emulation layer that also pretends that the current directory is a Unix path (at least as long as we're in a shell script). However, that is rather limiting, as Git for Windows also explores other ports of other Unix shells. One of those is BusyBox-w32's ash, which is a native port (i.e. *not* using any POSIX emulation layer, and certainly not emulating Unix paths).

As a consequence, the ISO-8859-1 test in t9350-fast-export (which tries to set GIT_AUTHOR_NAME to a ISO-8859-1 encoded value) *must* fail in that setup. So let's detect when it would fail (due to an environment being purely kept UTF-8 encoded), and skip that test in that case.

The bash just stops in those instances, does not even execute any commands after the echo command. Let's just work around this by running the Bash snippet only in MSYS2's Bash: its `SHELL` variable has the `.exe` suffix, and neither WSL's nor BusyBox' bash set the `SHELL` variable to a path with that suffix. In the latter case, we simply exit with code 127 (indicating that the command was not found) and fall back to the CONIN$/CONOUT$ method quietly.

Converting all at once proved hard to review, so starting with just apply lets conversion get started without the other commands being finished. The helper is being implemented as a drop in replacement for stash so that when it is complete it can simply be renamed and the shell script deleted. Delete the contents of the apply_stash shell function and replace it with a call to stash--helper apply until pop is also converted.

In order to do that, `create` and `push` were adapted to work without `stash.sh`. For example, before this commit, `git stash create` called `git stash--helper create --message "$*"`. If it called `git stash--helper create "$@"`, then some of these changes wouldn't have been necessary. This commit also removes the word `helper` since now stash is called directly and not by a shell script.

So, `check_changes()` is called 2 times and `get_untracked_files()` 3 times. The old function `check_changes()` now consists of two functions: `get_untracked_files()` and `check_changes_tracked_files()`. These are the call chains for `push` and `create`: * `push_stash()` -> `do_push_stash()` -> `do_create_stash()` * `create_stash()` -> `do_create_stash()` To prevent calling the same functions over and over again, `check_changes()` inside `do_create_stash()` is now placed in the caller functions (`create_stash()` and `do_push_stash()`). This way `check_changes()` and `get_untracked files()` are called only one time. https://public-inbox.org/git/20180818223329.GJ11326@hank.intra.tgummerer.com/ Signed-off-by: Paul-Sebastian Ungureanu <ungureanupaulsebastian@gmail.com> --- builtin/stash.c | 52 ++++++++++++++++++++++++++++--------------------- 1 file changed, 30 insertions(+), 22 deletions(-) diff --git a/builtin/stash.c b/builtin/stash.c index 9bef5ddc4b..79275b995d 100644 --- a/builtin/stash.c +++ b/builtin/stash.c @@ -879,18 +879,18 @@ static int get_untracked_files(struct pathspec ps, int include_untracked, } /* - * The return value of `check_changes()` can be: + * The return value of `check_changes_tracked_files()` can be: * * < 0 if there was an error * = 0 if there are no changes. * > 0 if there are changes. */ -static int check_changes(struct pathspec ps, int include_untracked) + +static int check_changes_tracked_files(struct pathspec ps) { int result; struct rev_info rev; struct object_id dummy; - struct strbuf out = STRBUF_INIT; /* No initial commit. */ if (get_oid("HEAD", &dummy)) @@ -918,16 +918,28 @@ static int check_changes(struct pathspec ps, int include_untracked) if (diff_result_code(&rev.diffopt, result)) return 1; - if (include_untracked && get_untracked_files(ps, include_untracked, - &out)) { - strbuf_release(&out); - return 1; - } - - strbuf_release(&out); return 0; } +/* + * The function will fill `untracked_files` with the names of untracked files + * It will return 1 if there were any changes and 0 if there were not. + */ + +static int check_changes(struct pathspec ps, int include_untracked, + struct strbuf *untracked_files) +{ + int ret = 0; + if (check_changes_tracked_files(ps)) + ret = 1; + + if (include_untracked && get_untracked_files(ps, include_untracked, + untracked_files)) + ret = 1; + + return ret; +} + static int save_untracked_files(struct stash_info *info, struct strbuf *msg, struct strbuf files) { @@ -1134,7 +1146,7 @@ static int do_create_stash(struct pathspec ps, struct strbuf *stash_msg_buf, head_commit = lookup_commit(the_repository, &info->b_commit); } - if (!check_changes(ps, include_untracked)) { + if (!check_changes(ps, include_untracked, &untracked_files)) { ret = 1; goto done; } @@ -1159,8 +1171,7 @@ static int do_create_stash(struct pathspec ps, struct strbuf *stash_msg_buf, goto done; } - if (include_untracked && get_untracked_files(ps, include_untracked, - &untracked_files)) { + if (include_untracked) { if (save_untracked_files(info, &msg, untracked_files)) { if (!quiet) fprintf_ln(stderr, _("Cannot save " @@ -1241,18 +1252,14 @@ static int create_stash(int argc, const char **argv, const char *prefix) strbuf_join_argv(&stash_msg_buf, argc - 1, ++argv, ' '); memset(&ps, 0, sizeof(ps)); - ret = do_create_stash(ps, &stash_msg_buf, 0, 0, &info, NULL, 0); + if (!check_changes_tracked_files(ps)) + return 0; - if (!ret) + if (!(ret = do_create_stash(ps, &stash_msg_buf, 0, 0, &info, NULL, 0))) printf_ln("%s", oid_to_hex(&info.w_commit)); strbuf_release(&stash_msg_buf); - - /* - * ret can be 1 if there were no changes.

Just like we have `rebase.useBuiltin` to fall back to the scripted rebase, to give end users a way out when they discover a bug in the builtin command, this commit adds support for `stash.useBuiltin`. This is necessary because Git for Windows wants to ship the builtin stash earlier than core Git: Git for Windows v2.19.0 will come with the option of a drastically faster (if a lot less battle-tested) `git stash`. As the file name `git-stash` is already in use, let's rename the scripted backend to `git-legacy-stash`. To make the test suite pass with `stash.useBuiltin=false`, this commit also backports rudimentary support for `-q` (but only *just* enough to appease the test suite), and adds a super-ugly hack to force exit code 129 for `git stash -h`.

The former has a safety valve allowing to fall back to the scripted `rebase`, just in case that there is a bug in the builtin `rebase`: setting the config variable `rebase.useBuiltin` to `false` will fall back to using the scripted version. The latter did not have such a safety hatch. Let's reinstate the scripted interactive rebase backend so that `rebase.useBuiltin=false` will not use the builtin interactive rebase, just in case that an end user runs into a bug with the builtin version and needs to get out of the fix really quickly. This is necessary because Git for Windows wants to ship the builtin rebase/interactive rebase earlier than core Git: Git for Windows v2.19.0 will come with the option of a drastically faster (if a lot less battle-tested) `git rebase`/`git rebase -i`. As the file name `git-rebase--interactive` is already in use, let's rename the scripted backend to `git-legacy-rebase--interactive`. A couple of additional touch-ups are needed (such as teaching the builtin `rebase--interactive`, which assumed the role of the `rebase--helper`, to perform the two tricks to skip the unnecessary picks and to generate a new todo list) to make things work again.

This puts requirements on it to be thread safe so that callers like preload-index can call it from multiple threads. This was implemented with a single mutex and completion events which introduces contention between the calling threads. Simplify the threading model by making fscache thread specific. This allows us to remove the global mutex and synchronization events entirely and instead associate a fscache with every thread that requests one. This works well with the current multi-threading which divides the cache entries into blocks with a separate thread processing each block. At the end of each worker thread, if there is a fscache on the primary thread, merge the cached results from the worker into the primary thread cache. This enables us to reuse the cache later especially when scanning for untracked files. In testing, this reduced the time spent in preload_index() by about 25% and also reduced the CPU utilization significantly. On a repo with ~200K files, it reduced overall status times by ~12%.

To help debugging such things, we introduce the `open_in_gdb()` function which can be called at a code location where the segfault happens (or as close as one can get); This will open a new MinTTY window with a GDB that already attached to the current process.

It comes in handy when resetting many, many paths at once and wildcards are not an option (e.g. when the paths are generated by a tool). Note: we first parse the entire list and perform the actual reset action only in a second phase. Not only does this make things simpler, it also helps performance, as do_diff_cache() traverses the index and the (sorted) pathspecs in simultaneously to avoid unnecessary lookups.

Maybe git-am is broken? This was due to lookup_prog not being Unicode-aware. It was somehow missed in 2ee5a1a14ad17ff35f0ad52390a27fbbc41258f3. Note that the only problem in this function was calling GetFileAttributes instead of GetFileAttributesW. The calls to access() were fine because access() is a macro which resolves to mingw_access, which already handles Unicode correctly. But I changed lookup_prog to use _waccess directly so that we only convert the path to UTF-16 once.

Unfortunately this breaks pushing over the dump git protocol if used over a network connection. The detailed reasons for this breakage are (by courtesy of Jeff Preshing, quoted from ttps://groups.google.com/d/msg/msysgit/at8D7J-h7mw/eaLujILGUWoJ): ---------------------------------------------------------------------------- MinGW wraps Windows sockets in CRT file descriptors in order to mimic the functionality of POSIX sockets. This causes msvcrt.dll to treat sockets as Installable File System (IFS) handles, calling ReadFile, WriteFile, DuplicateHandle and CloseHandle on them. This approach works well in simple cases on recent versions of Windows, but does not support all usage patterns. In particular, using this approach, any attempt to read & write concurrently on the same socket (from one or more processes) will deadlock in a scenario where the read waits for a response from the server which is only invoked after the write. This is what send_pack currently attempts to do in the use_sideband codepath. ---------------------------------------------------------------------------- The new config option "sendpack.sideband" allows to override the side-band-64k capability of the server, and thus makes the dump git protocol work. Other transportation methods like ssh and http/https still benefit from the sideband channel, therefore the default value of "sendpack.sideband" is still true.

This applies to both 32bit and 64bit builds and makes it substantially harder to exploit security holes in Git by offering a much more unpredictable attack surface. ASLR interferes with GDB's ability to set breakpoints. A similar issue holds true when compiling with -O2 (in which case single-stepping is messed up because GDB cannot map the code back to the original source code properly). Therefore we simply enable ASLR only when an optimization flag is present in the CFLAGS, using it as an indicator that the developer does not want to debug in GDB anyway.

In other words, the return value is either 0 or points just after the dir separator. This assumption is not fulfilled when calling offset_1st_component() e.g. on UNC paths on Windows, e.g. "//my-server/my-share". In this case, offset_1st_component() returns the length of the entire string (which is correct, because stripping the last "component" would not result in a valid directory), yet the return value still does not point just after a dir separator. This assumption is most prominently seen in the setup_git_directory_gently_1() function, where we want to append a ".git" component and simply assume that there is already a dir separator. In the UNC example given above, this assumption is incorrect. As a consequence, Git will fail to handle a worktree at the top of a UNC share correctly. Let's fix this by adding a dir separator specifically for that case: we found that there is no first component in the path and it does not end in a dir separator? Then add it.

One such category starts with a backslash and is implicitly relative to the drive associated with the current working directory. Example: c: git clone https://github.com/git-for-windows/git \G4W should clone into C:\G4W. There is currently a problem with that, in that mingw_mktemp() does not expect the _wmktemp() function to prefix the absolute path with the drive prefix, and as a consequence, the resulting path does not fit into the originally-passed string buffer. The symptom is a "Result too large" error. Reported by Juan Carlos Arevalo Baeza.

This is different from Unix and standard Windows directories: both / and C:\ are reported with a trailing slash as current directories. If a Git worktree is located there, Git is not quite prepared for that: while it does manage to find the .git directory/file, it returns as length of the top-level directory's path *one more* than the length of the current directory, and setup_git_directory_gently() would then return an undefined string as prefix. In practice, this undefined string usually points to NUL bytes, and does not cause much harm. Under rare circumstances that are really involved to reproduce (and not reliably so), the reported prefix could be a suffix string of Git's exec path, though. A careful analysis determined that this bug is unlikely to be exploitable, therefore we mark this as a regular bug fix.

To remedy that, we introduced the close_all_packs() function. Earlier, we made sure that the packs are released just before `git gc` is spawned, in case that gc wants to remove no-longer needed packs. But this developer forgot that gc itself also needs to let go of packs, e.g. when consolidating all packs via the --aggressive option. Likewise, `git repack -d` wants to delete obsolete packs and therefore needs to close all pack handles, too.

Those Unix shell quoting rules differ from the quoting rules applying to Windows' cmd and Powershell, making it a little awkward to quote command-line parameters properly when spawning other processes. In particular, git.exe passes arguments to subprocesses that are *not* intended to be interpreted as wildcards, and if they contain backslashes, those are not to be interpreted as escape characters, e.g. when passing Windows paths. Note: this is only a problem when calling MSYS2 executables, not when calling MINGW executables such as git.exe. However, we do call MSYS2 executables frequently, most notably when setting the use_shell flag in the child_process structure. There is no elegant way to determine whether the .exe file to be executed is an MSYS2 program or a MINGW one. But since the use case of passing a command line through the shell is so prevalent, we need to work around this issue at least when executing sh.exe. Let's introduce an ugly, hard-coded test whether argv[0] is "sh", and whether it refers to the MSYS2 Bash, to determine whether we need to quote the arguments differently than usual. That still does not fix the issue completely, but at least it is something. Incidentally, this also fixes the problem where `git clone \\server\repo` failed due to incorrect handling of the backslashes when handing the path to the git-upload-pack process. We need to take care to quote not only whitespace, but also curly brackets. As aliases frequently go through the MSYS2 Bash, and as aliases frequently get parameters such as HEAD@{yesterday}, let's make sure that this does not regress by adding a test case for that.

These files contain information about the time spent. So we need a way to measure time. While we could use `date +%s` for that, this will give us only seconds, i.e. very coarse-grained timings. GNU `date` supports `date +%s.%N` (i.e. nanosecond-precision output), but there is no equivalent in BSD `date` (read: on macOS, we would not be able to obtain precise timings). So let's introduce `test-tool date getnanos`, with an optional start time, that outputs preciser values. Granted, it is a bit pointless to try measuring times accurately in shell scripts, certainly to nanosecond precision. But it is better than second-granularity.

To make things a bit easier to understand, we refrain from using the `matrix` feature here because (while it is powerful) it can be a bit confusing to users who are not familiar with CI setups. Therefore, we use a separate phase even for similar configurations (such as GCC vs Clang on Linux, GCC vs Clang on macOS). Also, we make use of the shiny new feature we just introduced where the test suite can output JUnit-style .xml files. This information is made available in a nice UI that allows the viewer to filter by phase and/or test number, and to see trends such as: number of (failing) tests, time spent running the test suite, etc. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> --- azure-pipelines.yml | 325 ++++++++++++++++++++++++++++++++++++++++++ ci/mount-fileshare.sh | 26 ++++ 2 files changed, 351 insertions(+) create mode 100644 azure-pipelines.yml create mode 100755 ci/mount-fileshare.sh diff --git a/azure-pipelines.yml b/azure-pipelines.yml new file mode 100644 index 0000000000..4dc6fea129 --- /dev/null +++ b/azure-pipelines.yml @@ -0,0 +1,325 @@ +resources: +- repo: self + fetchDepth: 1 + +phases: +- phase: linux_clang + displayName: linux-clang + condition: succeeded() + queue: + name: Hosted Ubuntu 1604 + steps: + -

So far, we do this "manually". However, in the next few commits we want to teach the test suite to optionally re-run scripts with different options, therefore we will have to have a consistent way to stop daemons. Let's introduce `test_atexit`, which is loosely modeled after `test_when_finished` (but has a broader scope: rather than running the commands after the current test case, run them when the test script finishes, and also run them when the `--immediate` option is in effect).

For test failures, this usually means that you want to see the detailed trace of the failing tests. With Travis CI, we passed the `--verbose-log` option to get those traces. However, that seems excessive, as we do not need/use the logs in almost all of those cases: only when a test fails do we have a way to include the trace. So let's do something different when using Azure DevOps: let's run all the tests with `--quiet` first, and only if a failure is encountered, try to trace the commands as they are executed. Of course, we cannot turn on `--verbose-log` after the fact. So let's just re-run the test with all the same options, adding `--verbose-log`. And then munging the output file into the JUnit XML on the fly. Note: there is an off chance that re-running the test in verbose mode "fixes" the failures (and this does happen from time to time!). That is a possibility we should be able to live with. Ideally, we would label this as "Passed upon rerun", and Azure Pipelines even know about that outcome, but it is not available when using the JUnit XML format for now: https://github.com/Microsoft/azure-pipelines-agent/blob/master/src/Agent.Worker/TestResults/JunitResultReader.cs Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> --- t/test-lib.sh | 34 +++++++++++++++++++++++++++++++++- 1 file changed, 33 insertions(+), 1 deletion(-) diff --git a/t/test-lib.sh b/t/test-lib.sh index 514cd5ad2f..0fea4ad5e9 100644 --- a/t/test-lib.sh +++ b/t/test-lib.sh @@ -95,6 +95,13 @@ done,*) test "$(cat "$BASE.exit")" = 0 exit ;; +*' --write-junit-xml '*) + # record how to call this script *with* --verbose-log, in case + # we encounter a breakage + junit_rerun_options_sq="$(printf '%s\n' "$0" --verbose-log -x "$@" | + sed -e "s/'/'\\\\''/g" -e "s/^/'/" -e "s/\$/'/" | + tr '\012' ' ')" + ;; esac # For repeatability, reset the environment to known value. @@ -499,10 +506,31 @@ test_ok_ () { test_failure_ () { if test -n "$write_junit_xml" then + if test -z "$GIT_TEST_TEE_OUTPUT_FILE" + then + # clean up + test_atexit_handler + + # re-run with --verbose-log + echo "# Re-running: $junit_rerun_options_sq" >&2 + + cd "$TEST_DIRECTORY" && + eval "${TEST_SHELL_PATH}" "$junit_rerun_options_sq" \ + >/dev/null 2>&1 + status=$? + + say_color "" "$(test 0 = $status || + echo "not ")ok $test_count - (re-ran with trace)" + say "1..$test_count" + GIT_EXIT_OK=t + exit $status + fi + junit_insert="<failure message=\"not ok $test_count -" junit_insert="$junit_insert $(xml_attr_encode "$1")\">" junit_insert="$junit_insert $(xml_attr_encode \ - "$(printf '%s\n' "$@" | sed 1d)")" + "$(cat "$GIT_TEST_TEE_OUTPUT_FILE")")" + >"$GIT_TEST_TEE_OUTPUT_FILE" junit_insert="$junit_insert</failure>" write_junit_xml_testcase "$1" " $junit_insert" fi @@ -787,6 +815,10 @@ test_start_ () { if test -n "$write_junit_xml" then junit_start=$(test-tool date getnanos) + + # truncate output + test -z "$GIT_TEST_TEE_OUTPUT_FILE" || + >"$GIT_TEST_TEE_OUTPUT_FILE" fi } From c3ac43f99b03f0e61f917b58c84b5704cd024aa0 Mon Sep 17 00:00:00 2001 From: Johannes Schindelin <johannes.schindelin@gmx.de> Date: Fri, 31 Aug 2018 16:26:32 +0200 Subject: [PATCH 310/812] tests: record more stderr with --write-junit-xml in case of failure Sometimes, failures in a test case are actually caused by issues in earlier test cases.

The first fix caused Tcl to fail to compile the regexp, see msysGit issue 427. Here is another fix without using regexp, and using a more relaxed command line length limit to fix the original issue 387.

Earlier, libgit2 was nice enough to just re-use Git for Windows' C:\Program Files (x86)\Git\etc\gitconfig but with the upcoming Git for Windows 2.x, there would be more paths to search, as we will have 64-bit and 32-bit versions, and the corresponding config files will be in %PROGRAMFILES%\Git\mingw64\etc and ...\mingw32\etc, respectively. Worse: there are portable Git for Windows versions out there which live in totally unrelated directories, still. Therefore we came to a consensus to use `%PROGRAMDATA%\Git\config` as the location for shared Git settings that are of wider interest than just Git for Windows. Of course, the configuration in `%PROGRAMDATA%\Git\config` has the widest reach, therefore it must take the lowest precedence, i.e. Git for Windows can still override settings in its `etc/gitconfig` file.

Git for Windows introduced the `--no-lock-index` option a long time ago to fix that (it made it into Git for Windows v2.9.2(3)) by simply avoiding to write that file. The downside is that the periodic `git status` calls will be a little bit more wasteful because they may have to refresh the index repeatedly, only to throw away the updates when it exits. This cannot really be helped, though, as tools wanting to get a periodic update of the status have no way to predict when the user may want to lock the index herself. Sadly, a competing approach was submitted (by somebody who apparently has less work on their plate than this maintainer) that made it into v2.15.0 but is *different*: instead of a `git status`-only option, it is an option that comes *before* the Git command and is called differently, too. Let's give previous users a chance to upgrade to newer Git for Windows versions by handling the `--no-lock-index` option, still, though with a big fat warning.

Even if this value is not documented anywhere, CreateProcess() seems to work fine without complaints if hStdInput set to this value.

If you have an open-source +mindset and want to start contributing to Git, but primarily use a Windows machine, then you may +have trouble getting started. This guide is for you. + +Get the Source +-------------- + +Clone the [GitForWindows repository on GitHub](https://github.com/git-for-windows/git). +It is helpful to create your own fork for storing your development branches. + +Windows uses different line endings than Unix systems. See +[this GitHub article on working with line endings](https://help.github.com/articles/dealing-with-line-endings/#refreshing-a-repository-after-changing-line-endings) +if you have trouble with line endings. + +Build the Source +---------------- + +First, download and install the latest [Git for Windows SDK (64-bit)](https://github.com/git-for-windows/build-extra/releases/latest). +When complete, you can run the Git SDK, which creates a new Git Bash terminal window with +the additional development commands, such as `make`. + + As of time of writing, the SDK uses a different credential manager, so you may still want to use normal Git + Bash for interacting with your remotes. Alternatively, use SSH rather than HTTPS and + avoid credential manager problems. + +You should now be ready to type `make` from the root of your `git` source directory. +Here are some helpful variations: + +* `make -j[N] DEVELOPER=1`: Compile new sources using up to N concurrent processes. + The `DEVELOPER` flag turns on all warnings; code failing these warnings will not be + accepted upstream ("upstream" = "the core Git project"). +* `make clean`: Delete all compiled files. + +When running `make`, you can use `-j$(nproc)` to automatically use the number of processors +on your machine as the number of concurrent build processes. + +You can go deeper on the Windows-specific build process by reading the +[technical overview](https://github.com/git-for-windows/git/wiki/Technical-overview) or the +[guide to compiling Git with Visual Studio](https://github.com/git-for-windows/git/wiki/Compiling-Git-with-Visual-Studio). + +## Building `git` on Windows with Visual Studio + +The typical approach to building `git` is to use the standard `Makefile` with GCC, as +above. Developers working in a Windows environment may want to instead build with the +[Microsoft Visual C++ compiler and libraries toolset (MSVC)](https://blogs.msdn.microsoft.com/vcblog/2017/03/07/msvc-the-best-choice-for-windows/). +There are a few benefits to using MSVC over GCC during your development, including creating +symbols for debugging and [performance tracing](https://github.com/Microsoft/perfview#perfview-overview). + +There are two ways to build Git for Windows using MSVC. Each have their own merits. + +### Using SDK Command Line + +Use one of the following commands from the SDK Bash window to build Git for Windows: + +``` + make MSVC=1 -j12 + make MSVC=1 DEBUG=1 -j12 +``` + +The first form produces release-mode binaries; the second produces debug-mode binaries. +Both forms produce PDB files and can be debugged. However, the first is best for perf +tracing and the second is best for single-stepping. + +You can then open Visual Studio and select File -> Open -> Project/Solution and select +the compiled `git.exe` file. This creates a basic solution and you can use the debugging +and performance tracing tools in Visual Studio to monitor a Git process. Use the Debug +Properties page to set the working directory and command line arguments. + +Be sure to clean up before switching back to GCC (or to switch between debug and +release MSVC builds): + +``` + make MSVC=1 -j12 clean + make MSVC=1 DEBUG=1 -j12 clean +``` + +### Using `vs/master` Solution + +If you prefer working in Visual Studio with a solution full of projects, then there is a +branch in Git for Windows called [`vs/master`](https://github.com/git-for-windows/git/branches). +This branch is kept up-to-date with the `master` branch, except it has one more commit that +contains the solution and project files. Read [the wiki page on this approach](https://github.com/git-for-windows/git/wiki/Compiling-Git-with-Visual-Studio) for more information. + +I want to make a small warning before you start working on the `vs/master` branch. If you +create a new topic branch based on `vs/master`, you will need to rebase onto `master` before +you can submit a pull request. The commit at the tip of `vs/master` is not intended to ever +become part of the `master` branch. If you created a branch, `myTopic` based on `vs/master`, +then use the following rebase command to move it onto the `master` branch: + +``` +git rebase --onto master vs/master myTopic +``` + +What to Change? +--------------- + +Many new contributors ask: What should I start working on? + +One way to win big with the open-source community is to look at the +[issues page](https://github.com/git-for-windows/git/issues) and see if there are any issues that +you can fix quickly, or if anything catches your eye. + +You can also look at [the unofficial Chromium issues page](https://crbug.com/git) for +multi-platform issues. You can look at recent user questions on +[the Git mailing list](https://public-inbox.org/git). + +Or you can "scratch your own itch", i.e. address an issue you have with Git. The team at Microsoft where the Git for Windows maintainer works, for example, is focused almost entirely on [improving performance](https://blogs.msdn.microsoft.com/devops/2018/01/11/microsofts-performance-contributions-to-git-in-2017/). +We approach our work by finding something that is slow and try to speed it up. We start our +investigation by reliably reproducing the slow behavior, then running that example using +the MSVC build and tracing the results in PerfView. + +You could also think of something you wish Git could do, and make it do that thing! The +only concern I would have with this approach is whether or not that feature is something +the community also wants. If this excites you though, go for it! Don't be afraid to +[get involved in the mailing list](http://vger.kernel.org/vger-lists.html#git) early for +feedback on the idea. + +Test Your Changes +----------------- + +After you make your changes, it is important that you test your changes. Manual testing is +important, but checking and extending the existing test suite is even more important. You +want to run the functional tests to see if you broke something else during your change, and +you want to extend the functional tests to be sure no one breaks your feature in the future. + +### Functional Tests + +Navigate to the `t/` directory and type `make` to run all tests or use `prove` as +[described in the Git for Windows wiki](https://github.com/git-for-windows/git/wiki/Building-Git): + +``` +prove -j12 --state=failed,save ./t[0-9]*.sh +``` + +You can also run each test directly by running the corresponding shell script with a name +like `tNNNN-descriptor.sh`. + +If you are adding new functionality, you may need to create unit tests by creating +helper commands that test a very limited action. These commands are stored in `t/helpers`. +When adding a helper, be sure to add a line to `t/Makefile` and to the `.gitignore` for the +binary file you add. The Git community prefers functional tests using the full `git` +executable, so try to exercise your new code using `git` commands before creating a test +helper. + +To find out why a test failed, repeat the test with the `-x -v -d -i` options and then +navigate to the appropriate "trash" directory to see the data shape that was used for the +test failed step. + +Read [`t/README`](t/README) for more details. + +### Performance Tests + +If you are working on improving performance, you will need to be acquainted with the +performance tests in `t/perf`. There are not too many performance tests yet, but adding one +as your first commit in a patch series helps to communicate the boost your change provides. + +To check the change in performance across multiple versions of `git`, you can use the +`t/perf/run` script. For example, to compare the performance of `git rev-list` across the +`core/master` and `core/next` branches compared to a `topic` branch, you can run + +``` +cd t/perf +./run core/master core/next topic -- p0001-rev-list.sh +``` + +You can also set certain environment variables to help test the performance on different +repositories or with more repetitions. The full list is available in +[the `t/perf/README` file](t/perf/README), +but here are a few important ones: + +``` +GIT_PERF_REPO=/path/to/repo +GIT_PERF_LARGE_REPO=/path/to/large/repo +GIT_PERF_REPEAT_COUNT=10 +``` + +When running the performance tests on Linux, you may see a message "Can't locate JSON.pm in +@INC" and that means you need to run `sudo cpanm install JSON` to get the JSON perl package. + +For running performance tests, it can be helpful to set up a few repositories with strange +data shapes, such as: + +**Many objects:** Clone repos such as [Kotlin](https://github.com/jetbrains/kotlin), [Linux](https://github.com/torvalds/linux), or [Android](https://source.android.com/setup/downloading). + +**Many pack-files:** You can split a fresh clone into multiple pack-files of size at most +16MB by running `git repack -adfF --max-pack-size=16m`. See the +[`git repack` documentation](https://git-scm.com/docs/git-repack) for more information. +You can count the number of pack-files using `ls .git/objects/pack/*.pack | wc -l`. + +**Many loose objects:** If you already split your repository into multiple pack-files, then +you can pick one to split into loose objects using `cat .git/objects/pack/[id].pack | git unpack-objects`; +delete the `[id].pack` and `[id].idx` files after this. You can count the number of loose +bjects using `ls .git/objects/??/* | wc -l`. + +**Deep history:** Usually large repositories also have deep histories, but you can use the +[test-many-commits-1m repo](https://github.com/cirosantilli/test-many-commits-1m/) to +target deep histories without the overhead of many objects. One issue with this repository: +there are no merge commits, so you will need to use a different repository to test a "wide" +commit history. + +**Large Index:** You can generate a large index and repo by using the scripts in +`t/perf/repos`. There are two scripts. `many-files.sh` which will generate a repo with +same tree and blobs but different paths. Using `many-files.sh -d 5 -w 10 -f 9` will create +a repo with ~1 million entries in the index. `inflate-repo.sh` will use an existing repo +and copy the current work tree until it is a specified size. + +Test Your Changes on Linux +-------------------------- + +It can be important to work directly on the [core Git codebase](https://github.com/git/git), +such as a recent commit into the `master` or `next` branch that has not been incorporated +into Git for Windows. Also, it can help to run functional and performance tests on your +code in Linux before submitting patches to the mailing list, which focuses on many platforms. +The differences between Windows and Linux are usually enough to catch most cross-platform +issues. + +### Using the Windows Subsystem for Linux + +The [Windows Subsystem for Linux (WSL)](https://docs.microsoft.com/en-us/windows/wsl/install-win10) +allows you to [install Ubuntu Linux as an app](https://www.microsoft.com/en-us/store/p/ubuntu/9nblggh4msv6) +that can run Linux executables on top of the Windows kernel. Internally, +Linux syscalls are interpreted by the WSL, everything else is plain Ubuntu. + +First, open WSL (either type "Bash" in Cortana, or execute "bash.exe" in a CMD window). +Then install the prerequisites, and `git` for the initial clone: + +``` +sudo apt-get update +sudo apt-get install git gcc make libssl-dev libcurl4-openssl-dev \ + libexpat-dev tcl tk gettext git-email zlib1g-dev +``` + +Then, clone and build: + +``` +git clone https://github.com/git-for-windows/git +cd git +git remote add -f upstream https://github.com/git/git +make +``` + +Be sure to clone into `/home/[user]/` and not into any folder under `/mnt/?/` or your build +will fail due to colons in file names. + +### Using a Linux Virtual Machine with Hyper-V + +If you prefer, you can use a virtual machine (VM) to run Linux and test your changes in the +full environment. The test suite runs a lot faster on Linux than on Windows or with the WSL. +You can connect to the VM using an SSH terminal like +[PuTTY](https://www.chiark.greenend.org.uk/~sgtatham/putty/). + +The following instructions are for using Hyper-V, which is available in some versions of Windows. +There are many virtual machine alternatives available, if you do not have such a version installed. + +* [Download an Ubuntu Server ISO](https://www.ubuntu.com/download/server). +* Open [Hyper-V Manager](https://docs.microsoft.com/en-us/virtualization/hyper-v-on-windows/quick-start/enable-hyper-v). +* [Set up a virtual switch](https://docs.microsoft.com/en-us/virtualization/hyper-v-on-windows/quick-start/connect-to-network) + so your VM can reach the network. +* Select "Quick Create", name your machine, select the ISO as installation source, and un-check + "This virtual machine will run Windows." +* Go through the Ubuntu install process, being sure to select to install OpenSSH Server. +* When install is complete, log in and check the SSH server status with `sudo service ssh status`. + * If the service is not found, install with `sudo apt-get install openssh-server`. + * If the service is not running, then use `sudo service ssh start`. +* Use `shutdown -h now` to shutdown the VM, go to the Hyper-V settings for the VM, expand Network Adapter + to select "Advanced Features", and set the MAC address to be static (this can save your VM from losing + network if shut down incorrectly). +* Provide as many cores to your VM as you can (for parallel builds). +* Restart your VM, but do not connect. +* Use `ssh` in Git Bash, download [PuTTY](http://www.putty.org/), or use your favorite SSH client to connect to the VM through SSH. + +In order to build and use `git`, you will need the following libraries via `apt-get`: + +``` +sudo apt-get update +sudo apt-get install git gcc make libssl-dev libcurl4-openssl-dev \ + libexpat-dev tcl tk gettext git-email zlib1g-dev +``` + +To get your code from your Windows machine to the Linux VM, it is easiest to push the branch to your fork of Git and clone your fork in the Linux VM. + +Don't forget to set your `git` config with your preferred name, email, and editor. + +Polish Your Commits +------------------- + +Before submitting your patch, be sure to read the [coding guidelines](https://github.com/git/git/blob/master/Documentation/CodingGuidelines) +and check your code to match as best you can. This can be a lot of effort, but it saves +time during review to avoid style issues. + +The other possibly major difference between the mailing list submissions and GitHub PR workflows +is that each commit will be reviewed independently. Even if you are submitting a +patch series with multiple commits, each commit must stand on it's own and be reviewable +by itself. Make sure the commit message clearly explain the why of the commit not the how. +Describe what is wrong with the current code and how your changes have made the code better. + +When preparing your patch, it is important to put yourself in the shoes of the Git community. +Accepting a patch requires more justification than approving a pull request from someone on +your team. The community has a stable product and is responsible for keeping it stable. If +you introduce a bug, then they cannot count on you being around to fix it. When you decided +to start work on a new feature, they were not part of the design discussion and may not +even believe the feature is worth introducing. + +Questions to answer in your patch message (and commit messages) may include: +* Why is this patch necessary? +* How does the current behavior cause pain for users? +* What kinds of repositories are necessary for noticing a difference? +* What design options did you consider before writing this version? Do you have links to + code for those alternate designs? +* Is this a performance fix? Provide clear performance numbers for various well-known repos. + +Here are some other tips that we use when cleaning up our commits: + +* Commit messages should be wrapped at 76 columns per line (or less; 72 is also a + common choice). +* Make sure the commits are signed off using `git commit (-s|--signoff)`. See + [SubmittingPatches](https://github.com/git/git/blob/v2.8.1/Documentation/SubmittingPatches#L234-L286) + for more details about what this sign-off means. +* Check for whitespace errors using `git diff --check [base]...HEAD` or `git log --check`. +* Run `git rebase --whitespace=fix` to correct upstream issues with whitespace. +* Become familiar with interactive rebase (`git rebase -i`) because you will be reordering, + squashing, and editing commits as your patch or series of patches is reviewed. +* Make sure any shell scripts that you add have the executable bit set on them. This is + usually for test files that you add in the `/t` directory. You can use + `git add --chmod=+x [file]` to update it. You can test whether a file is marked as executable + using `git ls-files --stage \*.sh`; the first number is 100755 for executable files. +* Your commit titles should match the "area: change description" format. Rules of thumb: + * Choose "<area>: " prefix appropriately. + * Keep the description short and to the point. + * The word that follows the "<area>: " prefix is not capitalized. + * Do not include a full-stop at the end of the title. + * Read a few commit messages -- using `git log origin/master`, for instance -- to + become acquainted with the preferred commit message style. +* Build source using `make DEVELOPER=1` for extra-strict compiler warnings. + +Submit Your Patch +----------------- + +Git for Windows [accepts pull requests on GitHub](https://github.com/git-for-windows/git/pulls), but +these are reserved for Windows-specific improvements. For core Git, submissions are accepted on +[the Git mailing list](https://public-inbox.org/git). + +### Configure Git to Send Emails + +There are a bunch of options for configuring the `git send-email` command. These options can +be found in the documentation for +[`git config`](https://git-scm.com/docs/git-config) and +[`git send-email`](https://git-scm.com/docs/git-send-email). + +``` +git config --global sendemail.smtpserver <smtp server> +git config --global sendemail.smtpserverport 587 +git config --global sendemail.smtpencryption tls +git config --global sendemail.smtpuser <email address> +``` + +To avoid storing your password in the config file, store it in the Git credential manager: + +``` +$ git credential fill +protocol=smtp +host=<stmp server> +username=<email address> +password=password +``` + +Before submitting a patch, read the [Git documentation on submitting patches](https://github.com/git/git/blob/master/Documentation/SubmittingPatches). + +To construct a patch set, use the `git format-patch` command. There are three important options: + +* `--cover-letter`: If specified, create a `[v#-]0000-cover-letter.patch` file that can be + edited to describe the patch as a whole. If you previously added a branch description using + `git branch --edit-description`, you will end up with a 0/N mail with that description and + a nice overall diffstat. +* `--in-reply-to=[Message-ID]`: This will mark your cover letter as replying to the given + message (which should correspond to your previous iteration). To determine the correct Message-ID, + find the message you are replying to on [public-inbox.org/git](https://public-inbox.org/git) and take + the ID from between the angle brackets. + +* `--subject-prefix=[prefix]`: This defaults to [PATCH]. For subsequent iterations, you will want to + override it like `--subject-prefix="[PATCH v2]"`. You can also use the `-v` option to have it + automatically generate the version number in the patches. + +If you have multiple commits and use the `--cover-letter` option be sure to open the +`0000-cover-letter.patch` file to update the subject and add some details about the overall purpose +of the patch series. + +### Examples + +To generate a single commit patch file: +``` +git format-patch -s -o [dir] -1 +``` +To generate four patch files from the last three commits with a cover letter: +``` +git format-patch --cover-letter -s -o [dir] HEAD~4 +``` +To generate version 3 with four patch files from the last four commits with a cover letter: +``` +git format-patch --cover-letter -s -o [dir] -v 3 HEAD~4 +``` + +### Submit the Patch + +Run [`git send-email`](https://git-scm.com/docs/git-send-email), starting with a test email: + +``` +git send-email --to=yourself@address.com [dir with patches]/*.patch +``` + +After checking the receipt of your test email, you can send to the list and to any +potentially interested reviewers. + +``` +git send-email --to=git@vger.kernel.org --cc=<email1> --cc=<email2> [dir with patches]/*.patch +``` + +To submit a nth version patch (say version 3): + +``` +git send-email --to=git@vger.kernel.org --cc=<email1> --cc=<email2> \ + --in-reply-to=<the message id of cover letter of patch v2> [dir with patches]/*.patch +``` From 84bab7362e8f24c790f78d31ef5a250409bcfac8 Mon Sep 17 00:00:00 2001 From: Johannes Schindelin <johannes.schindelin@gmx.de> Date: Fri, 10 Jan 2014 16:16:03 -0600 Subject: [PATCH 341/812] README.md: Add a Windows-specific preamble Includes touch-ups by Philip Oakley.

Converting all at once proved hard to review, so starting with just apply lets conversion get started without the other commands being finished. The helper is being implemented as a drop in replacement for stash so that when it is complete it can simply be renamed and the shell script deleted. Delete the contents of the apply_stash shell function and replace it with a call to stash--helper apply until pop is also converted.

In order to do that, `create` and `push` were adapted to work without `stash.sh`. For example, before this commit, `git stash create` called `git stash--helper create --message "$*"`. If it called `git stash--helper create "$@"`, then some of these changes wouldn't have been necessary. This commit also removes the word `helper` since now stash is called directly and not by a shell script.

So, `check_changes()` is called 2 times and `get_untracked_files()` 3 times. The old function `check_changes()` now consists of two functions: `get_untracked_files()` and `check_changes_tracked_files()`. These are the call chains for `push` and `create`: * `push_stash()` -> `do_push_stash()` -> `do_create_stash()` * `create_stash()` -> `do_create_stash()` To prevent calling the same functions over and over again, `check_changes()` inside `do_create_stash()` is now placed in the caller functions (`create_stash()` and `do_push_stash()`). This way `check_changes()` and `get_untracked files()` are called only one time. https://public-inbox.org/git/20180818223329.GJ11326@hank.intra.tgummerer.com/ Signed-off-by: Paul-Sebastian Ungureanu <ungureanupaulsebastian@gmail.com> --- builtin/stash.c | 52 ++++++++++++++++++++++++++++--------------------- 1 file changed, 30 insertions(+), 22 deletions(-) diff --git a/builtin/stash.c b/builtin/stash.c index 9bef5ddc4b..79275b995d 100644 --- a/builtin/stash.c +++ b/builtin/stash.c @@ -879,18 +879,18 @@ static int get_untracked_files(struct pathspec ps, int include_untracked, } /* - * The return value of `check_changes()` can be: + * The return value of `check_changes_tracked_files()` can be: * * < 0 if there was an error * = 0 if there are no changes. * > 0 if there are changes. */ -static int check_changes(struct pathspec ps, int include_untracked) + +static int check_changes_tracked_files(struct pathspec ps) { int result; struct rev_info rev; struct object_id dummy; - struct strbuf out = STRBUF_INIT; /* No initial commit. */ if (get_oid("HEAD", &dummy)) @@ -918,16 +918,28 @@ static int check_changes(struct pathspec ps, int include_untracked) if (diff_result_code(&rev.diffopt, result)) return 1; - if (include_untracked && get_untracked_files(ps, include_untracked, - &out)) { - strbuf_release(&out); - return 1; - } - - strbuf_release(&out); return 0; } +/* + * The function will fill `untracked_files` with the names of untracked files + * It will return 1 if there were any changes and 0 if there were not. + */ + +static int check_changes(struct pathspec ps, int include_untracked, + struct strbuf *untracked_files) +{ + int ret = 0; + if (check_changes_tracked_files(ps)) + ret = 1; + + if (include_untracked && get_untracked_files(ps, include_untracked, + untracked_files)) + ret = 1; + + return ret; +} + static int save_untracked_files(struct stash_info *info, struct strbuf *msg, struct strbuf files) { @@ -1134,7 +1146,7 @@ static int do_create_stash(struct pathspec ps, struct strbuf *stash_msg_buf, head_commit = lookup_commit(the_repository, &info->b_commit); } - if (!check_changes(ps, include_untracked)) { + if (!check_changes(ps, include_untracked, &untracked_files)) { ret = 1; goto done; } @@ -1159,8 +1171,7 @@ static int do_create_stash(struct pathspec ps, struct strbuf *stash_msg_buf, goto done; } - if (include_untracked && get_untracked_files(ps, include_untracked, - &untracked_files)) { + if (include_untracked) { if (save_untracked_files(info, &msg, untracked_files)) { if (!quiet) fprintf_ln(stderr, _("Cannot save " @@ -1241,18 +1252,14 @@ static int create_stash(int argc, const char **argv, const char *prefix) strbuf_join_argv(&stash_msg_buf, argc - 1, ++argv, ' '); memset(&ps, 0, sizeof(ps)); - ret = do_create_stash(ps, &stash_msg_buf, 0, 0, &info, NULL, 0); + if (!check_changes_tracked_files(ps)) + return 0; - if (!ret) + if (!(ret = do_create_stash(ps, &stash_msg_buf, 0, 0, &info, NULL, 0))) printf_ln("%s", oid_to_hex(&info.w_commit)); strbuf_release(&stash_msg_buf); - - /* - * ret can be 1 if there were no changes.

Just like we have `rebase.useBuiltin` to fall back to the scripted rebase, to give end users a way out when they discover a bug in the builtin command, this commit adds support for `stash.useBuiltin`. This is necessary because Git for Windows wants to ship the builtin stash earlier than core Git: Git for Windows v2.19.0 will come with the option of a drastically faster (if a lot less battle-tested) `git stash`. As the file name `git-stash` is already in use, let's rename the scripted backend to `git-legacy-stash`. To make the test suite pass with `stash.useBuiltin=false`, this commit also backports rudimentary support for `-q` (but only *just* enough to appease the test suite), and adds a super-ugly hack to force exit code 129 for `git stash -h`.

The former has a safety valve allowing to fall back to the scripted `rebase`, just in case that there is a bug in the builtin `rebase`: setting the config variable `rebase.useBuiltin` to `false` will fall back to using the scripted version. The latter did not have such a safety hatch. Let's reinstate the scripted interactive rebase backend so that `rebase.useBuiltin=false` will not use the builtin interactive rebase, just in case that an end user runs into a bug with the builtin version and needs to get out of the fix really quickly. This is necessary because Git for Windows wants to ship the builtin rebase/interactive rebase earlier than core Git: Git for Windows v2.19.0 will come with the option of a drastically faster (if a lot less battle-tested) `git rebase`/`git rebase -i`. As the file name `git-rebase--interactive` is already in use, let's rename the scripted backend to `git-legacy-rebase--interactive`. A couple of additional touch-ups are needed (such as teaching the builtin `rebase--interactive`, which assumed the role of the `rebase--helper`, to perform the two tricks to skip the unnecessary picks and to generate a new todo list) to make things work again.

This is necessary because Git for Windows wants to use UTF-8 encoded strings throughout its code, and the main() function does not get the parameters in that encoding. To do that, we used the __wgetmainargs() function, which is not even a Win32 API function, but provided by the MINGW "runtime" instead. Obviously, this method would not work with any other compiler than GCC, and in preparation for compiling with Visual C++, we would like to avoid that. Lucky us, there is a much more elegant way: we simply implement wmain() and link with -municode. The command-line parameters are passed to wmain() encoded in UTF-16, as desired, and this method also works with Visual C++.

It is a perfectly legal way to define those constants, though, therefore we need to take care of defining O_ACCMODE accordingly. This is particularly important in order to keep our "open() can set errno to EISDIR" emulation working: it tests that (flags & O_ACCMODE) is not identical to O_RDONLY before going on to test specifically whether the file for which open() reported EACCES is, in fact, a directory.

See https://github.com/Microsoft/vcpkg On a first build, the vcpkg tools and the third party libraries are automatically downloaded and built. DLLs for the third party libraries are copied to the top-level (and t/helper) directory to facilitate debugging. See compat/vcbuild/README. A series of .bat files are invoked by the Makefile to find the location of the installed version of Visual Studio and the associated compiler tools (essentially replicating the environment setup performed by a "Developer Command Prompt"). This should find the most recent VS2015 or VS2017 installation. Output from these scripts are used by the Makefile to define compiler and linker pathnames and -I and -L arguments. The build produces .pdb files for both debug and release builds. Note: This commit was squashed from an organic series of commits developed between 2016 and 2018 in Git for Windows' `master` branch. This combined commit eliminates the obsolete commits related to fetching NuGet packages for third party libraries. It is difficult to use NuGet packages for C/C++ sources because they may be built by earlier versions of the MSVC compiler and have CRT version and linking issues. Additionally, the C/C++ NuGet packages that were using tended to not be updated concurrently with the sources. And in the case of cURL and OpenSSL, this could expose us to security issues.

However, when running the test suite, it is not so helpful, in particular when the debug assertions are then suppressed anyway because we disable the invalid parameter checking (via invalidcontinue.obj, see the comment in config.mak.uname about that object for more information). So let's simply disable that window in Debug Mode (it is already disabled in Release Mode).

Based on the generator for Visual Studio versions <= 2008 (which used .sln/.vcproj files), this patch copy-edits the generator of the .vcproj files to a new generator that produces .vcxproj files ready for Visual Studio 2010 and later (or MSBuild). As the vcpkg system (which is used to build Git's dependencies) cannot run in parallel (it does not lock, wreaking havoc with files being accessed and written at the same time, letting the vcpkg processes stumble over each others' toes), we make libgit the root of the project dependency tree and initialize the vcpkg system in this project's PreBuildEvent.

otherwise potential users would still have to download the entire Git for Windows SDK. So let's just add a target in the Makefile that can be used to generate said solution; The generated files will then be committed so that they can be pushed to a branch ready to check out by Visual Studio users. To make things even more useful, we also generate and commit other files that are required to run the test suite, such as templates and bin-wrappers: with this, developers can run the test suite in a regular Git Bash (that is part of a regular Git for Windows installation) after building the solution in Visual Studio.

A more sophisticated implementation may cache this data, e.g. for later reuse in calls to lstat. Make the dirent implementation pluggable so that it can be switched at runtime, e.g. based on a config option. Define a base DIR structure with pointers to readdir/closedir that match the opendir implementation (i.e. similar to vtable pointers in OOP). Define readdir/closedir so that they call the function pointers in the DIR structure. This allows to choose the opendir implementation on a call-by-call basis. Move the fixed sized dirent.d_name buffer to the dirent-specific DIR structure, as d_name may be implementation specific (e.g. a caching implementation may just set d_name to point into the cache instead of copying the entire file name string).

Windows operating system APIs seem to be much better at scanning the status of entire directories than checking single files. Add an lstat implementation that uses a cache for lstat data. Cache misses read the entire parent directory and add it to the cache. Subsequent lstat calls for the same directory are served directly from the cache. Also implement opendir / readdir / closedir so that they create and use directory listings in the cache. The cache doesn't track file system changes and doesn't plug into any modifying file APIs, so it has to be explicitly enabled for git functions that don't modify the working copy. Note: in an earlier version of this patch, the cache was always active and tracked file system changes via ReadDirectoryChangesW. However, this was much more complex and had negative impact on the performance of modifying git commands such as 'git checkout'.

This limitation is also evident in Windows Explorer, cmd.exe and many other applications (including IDEs). Particularly annoying is that most Windows APIs return bogus error codes if a relative path only barely exceeds MAX_PATH in conjunction with the current directory, e.g. ERROR_PATH_NOT_FOUND / ENOENT instead of the infinitely more helpful ERROR_FILENAME_EXCED_RANGE / ENAMETOOLONG. Many Windows wide char APIs support longer than MAX_PATH paths through the file namespace prefix ('\\?\' or '\\?\UNC\') followed by an absolute path. Notable exceptions include functions dealing with executables and the current directory (CreateProcess, LoadLibrary, Get/SetCurrentDirectory) as well as the entire shell API (ShellExecute, SHGetSpecialFolderPath...). Introduce a handle_long_path function to check the length of a specified path properly (and fail with ENAMETOOLONG), and to optionally expand long paths using the '\\?\' file namespace prefix. Short paths will not be modified, so we don't need to worry about device names (NUL, CON, AUX). Contrary to MSDN docs, the GetFullPathNameW function doesn't seem to be limited to MAX_PATH (at least not on Win7), so we can use it to do the heavy lifting of the conversion (translate '/' to '\', eliminate '.' and '..', and make an absolute path). Add long path error checking to xutftowcs_path for APIs with hard MAX_PATH limit. Add a new MAX_LONG_PATH constant and xutftowcs_long_path function for APIs that support long paths. While improved error checking is always active, long paths support must be explicitly enabled via 'core.longpaths' option. This is to prevent end users to shoot themselves in the foot by checking out files that Windows Explorer, cmd/bash or their favorite IDE cannot handle. Test suite: Test the case is when the full pathname length of a dir is close to 260 (MAX_PATH).

With this patch, the bash will be executed through strace if the environment variable GIT_STRACE_COMMANDS is set, which comes in real handy when investigating issues in the test suite. Also support passing a path to a log file via GIT_STRACE_COMMANDS to force Git to call strace.exe with the `-o <path>` argument, i.e. to log into a file rather than print the log directly. That comes in handy when the output would otherwise misinterpreted by a calling process as part of Git's output. Note: the values "1", "yes" or "true" are *not* specifying paths, but tell Git to let strace.exe log directly to the console.

The first and more obvious behavior is "Installer Detection", where Windows sometimes decides (by looking at things like the file name and even sequences of bytes within the executable) that an executable is an installer and should run elevated (causing the well-known popup dialog to appear). In Git's context, subcommands such as "git patch-id" or "git update-index" fall prey to this behavior. The second and more confusing behavior is "File Virtualization". It means that when files are written without having write permission, it does not fail (as expected), but they are instead redirected to somewhere else. When the files are read, the original contents are returned, though, not the ones that were just written somewhere else. Even more confusing, not all write accesses are redirected; Trying to write to write-protected .exe files, for example, will fail instead of redirecting. In addition to being unwanted behavior, File Virtualization causes dramatic slowdowns in Git (see for instance http://code.google.com/p/msysgit/issues/detail?id=320). There are two ways to prevent those two behaviors: Either you embed an application manifest within all your executables, or you add an external manifest (a file with the same name followed by .manifest) to all your executables. Since Git's builtins are hardlinked (or copied), it is simpler and more robust to embed a manifest. A recent enough MSVC compiler should already embed a working internal manifest, but for MinGW you have to do so by hand. Very lightly tested on Wine, where like on Windows XP it should not make any difference.

Rather than using -fstack-protector, we use -fstack-protector-strong because it strikes a better balance between how much code is affected and the performance impact.

Gettext uses setlocale() to determine the output encoding for translated text, however, MSVCRT's setlocale() doesn't support UTF-8. As a result, translated text is encoded in system encoding (GetAPC()), and non-ASCII chars are mangled in console output. Use gettext's bind_textdomain_codeset() to force the encoding to UTF-8 on native Windows. In this developers' setup, HAVE_LIBCHARSET_H is apparently defined, but we *really* want to override the locale_charset() here.

However, this is not the case with terminal windows other than `cmd.exe`'s, e.g. with MSys2's own `mintty`. Non-cmd terminals such as `mintty` still have to have a Win32 Console to be proper console programs, but have to hide the Win32 Console to be able to provide more flexibility (such as being resizeable not only vertically but also horizontally). By writing to that Win32 Console, `git_terminal_prompt()` manages only to send the prompt to nowhere and to wait for input from a Console to which the user has no access. This commit introduces a function specifically to support `mintty` -- or other terminals that are compatible with MSys2's `/dev/tty` emulation. We use the `TERM` environment variable as an indicator for that: if the value starts with "xterm" (such as `mintty`'s "xterm_256color"), we prefer to let `xterm_prompt()` handle the user interaction. The most prominent user of `git_terminal_prompt()` is certainly `git-remote-https.exe`. It is an interesting use case because both `stdin` and `stdout` are redirected when Git calls said executable, yet it still wants to access the terminal. When running inside a `mintty`, the terminal is not accessible to the `git-remote-https.exe` program, though, because it is a MinGW program and the `mintty` terminal is not backed by a Win32 console. To solve that problem, we simply call out to the shell -- which is an *MSys2* program and can therefore access `/dev/tty`.

It also doesn't work for terminal emulators that hide the native console window (such as mintty), and 'TERM=xterm*' is not necessarily a reliable indicator for such terminals. The new shell_prompt() function, on the other hand, works fine for both MSys1 and MSys2, in native console windows as well as mintty, and properly supports Unicode. It just needs bash on the path (for 'read -s', which is bash-specific). On Windows, try to use the shell to read from the terminal. If that fails with ENOENT (i.e. bash was not found), use CONIN/OUT as fallback. Note: To test this, create a UTF-8 credential file with non-ASCII chars, e.g. in git-bash: 'echo url=http://täst.com > cred.txt'. Then in git-cmd, 'git credential fill <cred.txt' works (shell version), while calling git without the git-wrapper (i.e. 'mingw64\bin\git credential fill <cred.txt') mangles non-ASCII chars in both console output and input.

Another debugging technique, used a lot by this here coder, is to run certain executables via gdb by guarding a "gdb -args" call in bin-wrappers/git. Both techniques were disabled by 781f76b1(test-lib: redirect stdin of tests). Let's reinstate the ability to run an interactive shell by making the redirection optional: setting the TEST_NO_REDIRECT environment variable will skip the redirection.

But GPG might fail, and send error messages to stderr. And we simply do not show them to the user. Even worse: this swallows any interactive prompt for a passphrase. And detaches stderr from the tty so that the passphrase cannot be read. So while the first problem could be fixed (by printing the captured stderr upon error), the second problem cannot be easily fixed, and presents a major regression. So let's just revert commit efee9553a4f97b2ecd8f49be19606dd4cf7d9c28.

An unintended side-effect is that "cold-calling" into the POSIX emulation will start with a locale based on the current code page, something that Git for Windows is very ill-prepared for, as it expects to be able to pass a command-line containing non-ASCII characters to the shell without having those characters munged. One symptom of this behavior: when `git clone` or `git fetch` shell out to call `git-upload-pack` with a path that contains non-ASCII characters, the shell tried to interpret the entire command-line (including command-line parameters) as executable path, which obviously must fail.

Implement stat by opening the file with as little permissions as possible and calling GetFileInformationByHandle on it. This way, all link resoltion is handled by the Windows file system layer. If symlinks are disabled, use lstat() as before, but fail with ELOOP if a symlink would have to be resolved.

However, currently there is no error handling whatsoever if FindFirstFile() fails. Call FindFirstFile() before modifying the stat *buf output parameter and error out if the call fails. Note: The FindFirstFile() return value includes all the data that we get from GetFileAttributesEx(), so we could replace GetFileAttributesEx() with FindFirstFile(). We don't do that because GetFileAttributesEx() is about twice as fast for single files. I.e. we only pay the extra cost of calling FindFirstFile() in the rare case that we encounter a reparse point. Note: The indentation of the remaining reparse point code will be fixed in the next patch.

Symlinks of wrong type simply don't work. This even affects core Win32 APIs (e.g. DeleteFile() refuses to delete directory symlinks). However, CreateFile() with FILE_FLAG_BACKUP_SEMANTICS doesn't seem to care. Check the target type by first creating a tentative file symlink, opening it, and checking the type of the resulting handle. If it is a directory, recreate the symlink with the directory flag set. It is possible to create symlinks before the target exists (or in case of symlinks to symlinks: before the target type is known). If this happens, create a tentative file symlink and postpone the directory decision: keep a list of phantom symlinks to be processed whenever a new directory is created in mingw_mkdir(). Limitations: This algorithm may fail if a link target changes from file to directory or vice versa, or if the target directory is created in another process.

This new flag is called SYMBOLIC_LINK_FLAG_ALLOW_UNPRIVILEGED_CREATE and has the numeric value 0x02. Previous Windows 10 versions will not understand that flag and return an ERROR_INVALID_PARAMETER, therefore we have to be careful to try passing that flag only when the build number indicates that it is supported. For more information about the new flag, see this blog post: https://blogs.windows.com/buildingapps/2016/12/02/symlinks-windows-10/ This patch is loosely based on the patch submitted by Samuel D.

This is a performance optimization. FSCACHE is a performance optimization available for Windows. It intercepts Posix-style lstat() calls into an in-memory directory using FindFirst/FindNext. It improves performance on Windows by catching the first lstat() call in a directory, using FindFirst/ FindNext to read the list of files (and attribute data) for the entire directory into the cache, and short-cut subsequent lstat() calls in the same directory. This gives a major performance boost on Windows. However, it does not remember "not found" directories. When STATUS runs and there are missing directories, the lstat() interception fails to find the parent directory and simply return ENOENT for the file -- it does not remember that the FindFirst on the directory failed. Thus subsequent lstat() calls in the same directory, each re-attempt the FindFirst. This completely defeats any performance gains. This can be seen by doing a sparse-checkout on a large repo and then doing a read-tree to reset the skip-worktree bits and then running status. This change reduced status times for my very large repo by 60%.

This patch teaches tons of Git commands to respect the config setting `core.longPaths = true`, including `pack-refs`, thereby fixing https://github.com/git-for-windows/git/issues/1218 Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> --- builtin/archive.c | 2 ++ builtin/bisect--helper.c | 2 ++ builtin/bundle.c | 2 ++ builtin/check-ref-format.c | 2 ++ builtin/clone.c | 1 + builtin/column.c | 2 ++ builtin/credential.c | 3 +++ builtin/fetch-pack.c | 2 ++ builtin/get-tar-commit-id.c | 2 ++ builtin/interpret-trailers.c | 2 ++ builtin/log.c | 1 + builtin/ls-remote.c | 2 ++ builtin/mailinfo.c | 2 ++ builtin/mailsplit.c | 2 ++ builtin/merge-index.c | 3 +++ builtin/merge-tree.c | 2 ++ builtin/mktag.c | 2 ++ builtin/mktree.c | 2 ++ builtin/pack-refs.c | 2 ++ builtin/prune-packed.c | 2 ++ builtin/prune.c | 3 +++ builtin/reflog.c | 1 + builtin/remote-ext.c | 2 ++ builtin/remote.c | 1 + builtin/rev-parse.c | 1 + builtin/show-index.c | 2 ++ builtin/show-ref.c | 2 ++ builtin/stripspace.c | 5 ++--- builtin/submodule--helper.c | 1 + builtin/upload-archive.c | 3 +++ credential-store.c | 3 +++ http-backend.c | 1 + refs.c | 2 +- 33 files changed, 63 insertions(+), 4 deletions(-) diff --git a/builtin/archive.c b/builtin/archive.c index d2455237ce..5c3f5a4678 100644 --- a/builtin/archive.c +++ b/builtin/archive.c @@ -9,6 +9,7 @@ #include "parse-options.h" #include "pkt-line.h" #include "sideband.h" +#include "config.h" static void create_output_file(const char *output_file) { @@ -94,6 +95,7 @@ int cmd_archive(int argc, const char **argv, const char *prefix) OPT_END() };

During an "add", a call is made to run_diff_files() which calls check_remove() for each index-entry. This calls lstat(). On Windows, the fscache code intercepts the lstat() calls and builds a private cache using the FindFirst/FindNext routines, which are much faster. Somewhat independent of this, is the preload-index code which distributes some of the start-up costs across multiple threads. We need to keep the call to read_cache() before parsing the pathspecs (and hence cannot use the pathspecs to limit any preload) because parse_pathspec() is using the index to determine whether a pathspec is, in fact, in a submodule. If we would not read the index first, parse_pathspec() would not error out on a path that is inside a submodule, and t7400-submodule-basic.sh would fail with not ok 47 - do not add files from a submodule We still want the nice preload performance boost, though, so we simply call read_cache_preload(&pathspecs) after parsing the pathspecs.

The current code in add_excludes() calls open() and then fstat() for a ".gitignore" file in each directory present in the worktree. Change that when fscache is enabled to call lstat() first and if present, call open(). This seems backwards because both lstat needs to do more work than fstat. But when fscache is enabled, fscache will already know if the .gitignore file exists and can completely avoid the IO calls. This works because of the lstat diversion to mingw_lstat when fscache is enabled. This reduced status times on a 350K file enlistment of the Windows repo on a NVMe SSD by 0.25 seconds.

Later when the ignore file was read, the buffer length did not match the stat.st_size field and we called die("cannot use <path> as an exclude file") Optimization Rationale ====================== The above optimization calls lstat() before open() primarily to ask fscache if the file exists. It gets the current stat-data as a side effect essentially for free (since we already have it in memory). If the file does not exist, it does not need to call open(). And since very few directories have .gitignore files, we can greatly reduce time spent in the filesystem. Discussion of Fix ================= The above optimization calls lstat() rather than stat() because the fscache only intercepts lstat() calls. Calls to stat() stay directed to the mingw_stat() completly bypassing fscache. Furthermore, calls to mingw_stat() always call {open, fstat, close} so that symlinks are properly dereferenced, which adds *additional* open/close calls on top of what the original code in dir.c is doing. Since the problem only manifests for symlinks, we add code to overwrite the stat-data when the path is a symlink. This preserves the effect of the performance gains provided by the fscache in the normal case.

This is a total waste of time and effort on a filesystem that orders data writes properly, but can be useful for filesystems that do not use journalling (traditional UNIX filesystems) or that only journal metadata and not file contents (OS X’s HFS+, or Linux ext3 with "data=writeback"). The most common file system on Windows (NTFS) does not guarantee that order, therefore a sudden loss of power (or any other event causing an unclean shutdown) would cause corrupt files (i.e. files filled with NULs). Therefore we need to change the default. Note that the documentation makes it sound as if this causes really bad performance. In reality, writing loose objects is something that is done only rarely, and only a handful of files at a time.

This is bad insofar as Git itself expects its signal handlers to run. A symptom is e.g. a left-behind .lock file that would not be left behind if the same operation was run, say, on Linux. To remedy this situation, we use an obscure trick: we inject a thread into the process that needs to be killed and to let that thread run the ExitProcess() function with the desired exit status. Thanks J Wyman for describing this trick. The advantage is that the ExitProcess() function lets the atexit handlers run. While this is still different from what Git expects (i.e. running a signal handler), in practice Git sets up signal handlers and atexit handlers that call the same code to clean up after itself. In case that the gentle method to terminate the process failed, we still fall back to calling TerminateProcess(), but in that case we now also make sure that processes spawned by the spawned process are terminated; TerminateProcess() does not give the spawned process a chance to do so itself. Please note that this change only affects how Git for Windows tries to terminate processes spawned by Git's own executables. Third-party software that *calls* Git and wants to terminate it *still* need to make sure to imitate this gentle method, otherwise this patch will not have any effect.

Which we do need to set because we need to pass in stdin/stdout/stderr to talk to the child processes. Sadly, this means that all file handles (unless marked via O_NOINHERIT) are inherited. This lead to problems in GVFS Git, where a long-running read-object hook is used to hydrate missing objects, and depending on the circumstances, might only be called *after* Git opened a file handle. Ideally, we would not open files without O_NOINHERIT unless *really* necessary (i.e. when we want to pass the opened file handle as standard handle into a child process), but apparently it is all-too-easy to introduce incorrect open() calls: this happened, and prevented updating a file after the read-object hook was started because the hook still held a handle on said file. Happily, there is a solution: as described in the "Old New Thing" https://blogs.msdn.microsoft.com/oldnewthing/20111216-00/?p=8873 there is a way, starting with Windows Vista, that lets us define precisely which handles should be inherited by the child process. And since we bumped the minimum Windows version for use with Git for Windows to Vista with v2.10.1 (i.e. a *long* time ago), we can use this method. So let's do exactly that. We need to make sure that the list of handles to inherit does not contain duplicates; Otherwise CreateProcessW() would fail with ERROR_INVALID_ARGUMENT. While at it, stop setting errno to ENOENT unless it really is the correct value. Also, fall back to not limiting handle inheritance under certain error conditions (e.g. on Windows 7, which is a lot stricter in what handles you can specify to limit to).

And similar to Git's builtins, the applets can be called via `busybox <command>`, or the BusyBox executable can be copied/hard-linked to the command name. The similarities do not end here. Just as with Git's builtins, it is problematic that BusyBox' hard-linked applets cannot easily be put into a .zip file: .zip archives have no concept of hard-links and therefore would store identical copies (and also extract identical copies, "inflating" the archive unnecessarily). To counteract that issue, MinGit already ships without hard-linked copies of the builtins, and the plan is to do the same with BusyBox' applets: simply ship busybox.exe as single executable, without hard-linked applets. To accommodate that, Git is being taught by this commit a very special trick, exploiting the fact that it is possible to call an executable with a command-line whose argv[0] is different from the executable's name: when `sh` is to be spawned, and no `sh` is found in the PATH, but busybox.exe is, use that executable (with unchanged argv). Likewise, if any executable to be spawned is not on the PATH, but busybox.exe is found, parse the output of `busybox.exe --help` to find out what applets are included, and if the command matches an included applet name, use busybox.exe to execute it.

This helps e.g. when trying to verify a Git for Windows installation without requiring to download a full Git for Windows SDK (which would use up 600+ megabytes of bandwidth, and over a gigabyte of disk space). Of course, it still requires the test helpers to be build *somewhere*, and the Git version should at least roughly match the version from which the test suite comes. At the same time, this new way to run the test suite allows to validate that a BusyBox-backed MinGit works as expected (verifying that BusyBox' functionality is enough to at least pass the test suite).

However, that limits esoteric test scenarios such as Git for Windows', where an end user installation has to ship with `iconv` for the sole purpose of being testable. That payload serves no other purpose. So let's just have a test helper (to be able to test Git, the test helpers have to be available, after all) to act as `iconv` replacement.

That also means that it does *not* use the Unix convention of separating the entries in the PATH variable using colons, but semicolons. However, there are also BusyBox ports to Windows which use a POSIX emulation layer such as Cygwin's or MSYS2's runtime, i.e. using colons as PATH separators. As a tell-tale, let's use the presence of semicolons in the PATH variable: on Unix, it is highly unlikely that it contains semicolons, and on Windows (without POSIX emulation), it is virtually guaranteed, as everybody should have both $SYSTEMROOT and $SYSTEMROOT/system32 in their PATH.

We already excluded test cases using such files from running on Windows when git.exe itself was tested. However, we still had two test cases that try to create such a file, and redirect stdin from such a file, respectively. This *seems* to work in Git for Windows' Bash due to an obscure feature inherited from Cygwin: illegal filename characters are simply mapped into/from a private UTF-8 page. Pure Win32 programs (such as git.exe) *still* cannot work with those files, of course, but at least Unix shell scripts pretend to be able to. This entire strategy breaks down when switching to any Unix shell lacking support for that private UTF-8 page trick, e.g. BusyBox-w32's ash.

There *are* some more native ports of Unix shells out there, though, most notably BusyBox-w32's ash. These native ports do not use any POSIX emulation layer (or at most a *very* thin one, choosing to avoid features such as fork() that are expensive to emulate on Windows), and they use native Windows paths (usually with forward slashes instead of backslashes, which is perfectly legal in almost all use cases). And here comes the problem: with a $PWD looking like, say, C:/git-sdk-64/usr/src/git/t/trash directory.t5813-proto-disable-ssh Git's test scripts get quite a bit confused, as their assumptions have been shattered. Not only does this path contain a colon (oh no!), it also does not start with a slash. This is a problem e.g. when constructing a URL as t5813 does it: ssh://remote$PWD. Not only is it impossible to separate the "host" from the path with a $PWD as above, even prefixing $PWD by a slash won't work, as /C:/git-sdk-64/... is not a valid path. As a workaround, detect when $PWD does not start with a slash on Windows, and simply strip the drive prefix, using an obscure feature of Windows paths: if an absolute Windows path starts with a slash, it is implicitly prefixed by the drive prefix of the current directory. As we are talking about the current directory here, anyway, that strategy works.

If we feed that path to CVS, it mistakes it for a separator between host and port, though. This has not been a problem so far because Git for Windows uses MSYS2's Bash using a POSIX emulation layer that also pretends that the current directory is a Unix path (at least as long as we're in a shell script). However, that is rather limiting, as Git for Windows also explores other ports of other Unix shells.

The bash just stops in those instances, does not even execute any commands after the echo command. Let's just work around this by running the Bash snippet only in MSYS2's Bash: its `SHELL` variable has the `.exe` suffix, and neither WSL's nor BusyBox' bash set the `SHELL` variable to a path with that suffix. In the latter case, we simply exit with code 127 (indicating that the command was not found) and fall back to the CONIN$/CONOUT$ method quietly.

This puts requirements on it to be thread safe so that callers like preload-index can call it from multiple threads. This was implemented with a single mutex and completion events which introduces contention between the calling threads. Simplify the threading model by making fscache thread specific. This allows us to remove the global mutex and synchronization events entirely and instead associate a fscache with every thread that requests one. This works well with the current multi-threading which divides the cache entries into blocks with a separate thread processing each block. At the end of each worker thread, if there is a fscache on the primary thread, merge the cached results from the worker into the primary thread cache. This enables us to reuse the cache later especially when scanning for untracked files. In testing, this reduced the time spent in preload_index() by about 25% and also reduced the CPU utilization significantly. On a repo with ~200K files, it reduced overall status times by ~12%.

To help debugging such things, we introduce the `open_in_gdb()` function which can be called at a code location where the segfault happens (or as close as one can get); This will open a new MinTTY window with a GDB that already attached to the current process.

Update fscache to call the underlying kernel API NtQueryDirectoryFile so that we can do the buffer management ourselves. That allows us to allocate a single buffer for the lifetime of the cache and reuse it for each directory. This change improves performance of 'git status' by 18% in a repo with ~200K files and 30k folders. Documentation for NtQueryDirectoryFile can be found at: https://docs.microsoft.com/en-us/windows-hardware/drivers/ddi/content/ntifs/nf-ntifs-ntquerydirectoryfile https://docs.microsoft.com/en-us/windows/desktop/FileIO/file-attribute-constants https://docs.microsoft.com/en-us/windows/desktop/fileio/reparse-point-tags To determine if the specified directory is a symbolic link, inspect the FileAttributes member to see if the FILE_ATTRIBUTE_REPARSE_POINT flag is set. If so, EaSize will contain the reparse tag (this is a so far undocumented feature, but confirmed by the NTFS developers). To determine if the reparse point is a symbolic link (and not some other form of reparse point), test whether the tag value equals the value IO_REPARSE_TAG_SYMLINK.

It comes in handy when resetting many, many paths at once and wildcards are not an option (e.g. when the paths are generated by a tool). Note: we first parse the entire list and perform the actual reset action only in a second phase. Not only does this make things simpler, it also helps performance, as do_diff_cache() traverses the index and the (sorted) pathspecs in simultaneously to avoid unnecessary lookups. This feature is marked experimental because it is still under review in the upstream Git project.

Unfortunately this breaks pushing over the dump git protocol if used over a network connection. The detailed reasons for this breakage are (by courtesy of Jeff Preshing, quoted from ttps://groups.google.com/d/msg/msysgit/at8D7J-h7mw/eaLujILGUWoJ): ---------------------------------------------------------------------------- MinGW wraps Windows sockets in CRT file descriptors in order to mimic the functionality of POSIX sockets. This causes msvcrt.dll to treat sockets as Installable File System (IFS) handles, calling ReadFile, WriteFile, DuplicateHandle and CloseHandle on them. This approach works well in simple cases on recent versions of Windows, but does not support all usage patterns. In particular, using this approach, any attempt to read & write concurrently on the same socket (from one or more processes) will deadlock in a scenario where the read waits for a response from the server which is only invoked after the write. This is what send_pack currently attempts to do in the use_sideband codepath. ---------------------------------------------------------------------------- The new config option "sendpack.sideband" allows to override the side-band-64k capability of the server, and thus makes the dump git protocol work. Other transportation methods like ssh and http/https still benefit from the sideband channel, therefore the default value of "sendpack.sideband" is still true.

This applies to both 32bit and 64bit builds and makes it substantially harder to exploit security holes in Git by offering a much more unpredictable attack surface. ASLR interferes with GDB's ability to set breakpoints. A similar issue holds true when compiling with -O2 (in which case single-stepping is messed up because GDB cannot map the code back to the original source code properly). Therefore we simply enable ASLR only when an optimization flag is present in the CFLAGS, using it as an indicator that the developer does not want to debug in GDB anyway.

In other words, the return value is either 0 or points just after the dir separator. This assumption is not fulfilled when calling offset_1st_component() e.g. on UNC paths on Windows, e.g. "//my-server/my-share". In this case, offset_1st_component() returns the length of the entire string (which is correct, because stripping the last "component" would not result in a valid directory), yet the return value still does not point just after a dir separator. This assumption is most prominently seen in the setup_git_directory_gently_1() function, where we want to append a ".git" component and simply assume that there is already a dir separator. In the UNC example given above, this assumption is incorrect. As a consequence, Git will fail to handle a worktree at the top of a UNC share correctly. Let's fix this by adding a dir separator specifically for that case: we found that there is no first component in the path and it does not end in a dir separator? Then add it.

This is different from Unix and standard Windows directories: both / and C:\ are reported with a trailing slash as current directories. If a Git worktree is located there, Git is not quite prepared for that: while it does manage to find the .git directory/file, it returns as length of the top-level directory's path *one more* than the length of the current directory, and setup_git_directory_gently() would then return an undefined string as prefix. In practice, this undefined string usually points to NUL bytes, and does not cause much harm. Under rare circumstances that are really involved to reproduce (and not reliably so), the reported prefix could be a suffix string of Git's exec path, though. A careful analysis determined that this bug is unlikely to be exploitable, therefore we mark this as a regular bug fix.

One such category starts with a backslash and is implicitly relative to the drive associated with the current working directory. Example: c: git clone https://github.com/git-for-windows/git \G4W should clone into C:\G4W. There is currently a problem with that, in that mingw_mktemp() does not expect the _wmktemp() function to prefix the absolute path with the drive prefix, and as a consequence, the resulting path does not fit into the originally-passed string buffer.

Those Unix shell quoting rules differ from the quoting rules applying to Windows' cmd and Powershell, making it a little awkward to quote command-line parameters properly when spawning other processes. In particular, git.exe passes arguments to subprocesses that are *not* intended to be interpreted as wildcards, and if they contain backslashes, those are not to be interpreted as escape characters, e.g. when passing Windows paths. Note: this is only a problem when calling MSYS2 executables, not when calling MINGW executables such as git.exe. However, we do call MSYS2 executables frequently, most notably when setting the use_shell flag in the child_process structure. There is no elegant way to determine whether the .exe file to be executed is an MSYS2 program or a MINGW one. But since the use case of passing a command line through the shell is so prevalent, we need to work around this issue at least when executing sh.exe. Let's introduce an ugly, hard-coded test whether argv[0] is "sh", and whether it refers to the MSYS2 Bash, to determine whether we need to quote the arguments differently than usual. That still does not fix the issue completely, but at least it is something. Incidentally, this also fixes the problem where `git clone \\server\repo` failed due to incorrect handling of the backslashes when handing the path to the git-upload-pack process. We need to take care to quote not only whitespace, but also curly brackets. As aliases frequently go through the MSYS2 Bash, and as aliases frequently get parameters such as HEAD@{yesterday}, let's make sure that this does not regress by adding a test case for that.

This is the reason that the warning RUNTIME_PREFIX requested, but prefix computation failed. [...] to be printed. In t0061, we did not expect that to happen, and it actually did not happen in the normal case, because bin-wrappers/test-tool specifically sets GIT_TEXTDOMAINDIR (and as a consequence, nothing in test-tool wants to know about the runtime prefix). However, with --with-dashes, bin-wrappers/test-tool is no longer called, but t/helper/test-tool is called directly. So let's just ignore the RUNTIME_PREFIX warning.

These files contain information about the time spent. So we need a way to measure time. While we could use `date +%s` for that, this will give us only seconds, i.e. very coarse-grained timings. GNU `date` supports `date +%s.%N` (i.e. nanosecond-precision output), but there is no equivalent in BSD `date` (read: on macOS, we would not be able to obtain precise timings). So let's introduce `test-tool date getnanos`, with an optional start time, that outputs preciser values. Granted, it is a bit pointless to try measuring times accurately in shell scripts, certainly to nanosecond precision. But it is better than second-granularity.

To make things a bit easier to understand, we refrain from using the `matrix` feature here because (while it is powerful) it can be a bit confusing to users who are not familiar with CI setups. Therefore, we use a separate phase even for similar configurations (such as GCC vs Clang on Linux, GCC vs Clang on macOS). Also, we make use of the shiny new feature we just introduced where the test suite can output JUnit-style .xml files. This information is made available in a nice UI that allows the viewer to filter by phase and/or test number, and to see trends such as: number of (failing) tests, time spent running the test suite, etc. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> --- azure-pipelines.yml | 325 ++++++++++++++++++++++++++++++++++++++++++ ci/mount-fileshare.sh | 26 ++++ 2 files changed, 351 insertions(+) create mode 100644 azure-pipelines.yml create mode 100755 ci/mount-fileshare.sh diff --git a/azure-pipelines.yml b/azure-pipelines.yml new file mode 100644 index 0000000000..c50fdf9429 --- /dev/null +++ b/azure-pipelines.yml @@ -0,0 +1,325 @@ +resources: +- repo: self + fetchDepth: 1 + +phases: +- phase: linux_clang + displayName: linux-clang + condition: succeeded() + queue: + name: Hosted Ubuntu 1604 + steps: + -

So far, we do this "manually". However, in the next few commits we want to teach the test suite to optionally re-run scripts with different options, therefore we will have to have a consistent way to stop daemons. Let's introduce `test_atexit`, which is loosely modeled after `test_when_finished` (but has a broader scope: rather than running the commands after the current test case, run them when the test script finishes, and also run them when the `--immediate` option is in effect).

For test failures, this usually means that you want to see the detailed trace of the failing tests. With Travis CI, we passed the `--verbose-log` option to get those traces. However, that seems excessive, as we do not need/use the logs in almost all of those cases: only when a test fails do we have a way to include the trace. So let's do something different when using Azure DevOps: let's run all the tests with `--quiet` first, and only if a failure is encountered, try to trace the commands as they are executed. Of course, we cannot turn on `--verbose-log` after the fact. So let's just re-run the test with all the same options, adding `--verbose-log`. And then munging the output file into the JUnit XML on the fly. Note: there is an off chance that re-running the test in verbose mode "fixes" the failures (and this does happen from time to time!). That is a possibility we should be able to live with. Ideally, we would label this as "Passed upon rerun", and Azure Pipelines even know about that outcome, but it is not available when using the JUnit XML format for now: https://github.com/Microsoft/azure-pipelines-agent/blob/master/src/Agent.Worker/TestResults/JunitResultReader.cs Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> --- t/test-lib.sh | 34 +++++++++++++++++++++++++++++++++- 1 file changed, 33 insertions(+), 1 deletion(-) diff --git a/t/test-lib.sh b/t/test-lib.sh index ca1acd61d1..c7ae5aec15 100644 --- a/t/test-lib.sh +++ b/t/test-lib.sh @@ -95,6 +95,13 @@ done,*) test "$(cat "$BASE.exit")" = 0 exit ;; +*' --write-junit-xml '*) + # record how to call this script *with* --verbose-log, in case + # we encounter a breakage + junit_rerun_options_sq="$(printf '%s\n' "$0" --verbose-log -x "$@" | + sed -e "s/'/'\\\\''/g" -e "s/^/'/" -e "s/\$/'/" | + tr '\012' ' ')" + ;; esac # For repeatability, reset the environment to known value. @@ -503,10 +510,31 @@ test_ok_ () { test_failure_ () { if test -n "$write_junit_xml" then + if test -z "$GIT_TEST_TEE_OUTPUT_FILE" + then + # clean up + test_atexit_handler + + # re-run with --verbose-log + echo "# Re-running: $junit_rerun_options_sq" >&2 + + cd "$TEST_DIRECTORY" && + eval "${TEST_SHELL_PATH}" "$junit_rerun_options_sq" \ + >/dev/null 2>&1 + status=$? + + say_color "" "$(test 0 = $status || + echo "not ")ok $test_count - (re-ran with trace)" + say "1..$test_count" + GIT_EXIT_OK=t + exit $status + fi + junit_insert="<failure message=\"not ok $test_count -" junit_insert="$junit_insert $(xml_attr_encode "$1")\">" junit_insert="$junit_insert $(xml_attr_encode \ - "$(printf '%s\n' "$@" | sed 1d)")" + "$(cat "$GIT_TEST_TEE_OUTPUT_FILE")")" + >"$GIT_TEST_TEE_OUTPUT_FILE" junit_insert="$junit_insert</failure>" write_junit_xml_testcase "$1" " $junit_insert" fi @@ -791,6 +819,10 @@ test_start_ () { if test -n "$write_junit_xml" then junit_start=$(test-tool date getnanos) + + # truncate output + test -z "$GIT_TEST_TEE_OUTPUT_FILE" || + >"$GIT_TEST_TEE_OUTPUT_FILE" fi } From 5f86eb41fed1826d3223efa6c8d5ca13f6cda5ff Mon Sep 17 00:00:00 2001 From: Johannes Schindelin <johannes.schindelin@gmx.de> Date: Fri, 31 Aug 2018 16:26:32 +0200 Subject: [PATCH 586/812] tests: record more stderr with --write-junit-xml in case of failure Sometimes, failures in a test case are actually caused by issues in earlier test cases.

Work around this by just cutting off the command line at that length (actually, at a space boundary) in the hope that only negative refs are chucked: gitk will then do unnecessary work, but that is still better than flashing the gitk window and exiting with exit status 5 (which no Windows user is able to make sense of). The first fix caused Tcl to fail to compile the regexp, see msysGit issue 427. Here is another fix without using regexp, and using a more relaxed command line length limit to fix the original issue 387.

This is necessary because Git for Windows wants to use UTF-8 encoded strings throughout its code, and the main() function does not get the parameters in that encoding. To do that, we used the __wgetmainargs() function, which is not even a Win32 API function, but provided by the MINGW "runtime" instead. Obviously, this method would not work with any other compiler than GCC, and in preparation for compiling with Visual C++, we would like to avoid that. Lucky us, there is a much more elegant way: we simply implement wmain() and link with -municode. The command-line parameters are passed to wmain() encoded in UTF-16, as desired, and this method also works with Visual C++ after adjusting the MSVC linker flags to force it to use wmain().

It is a perfectly legal way to define those constants, though, therefore we need to take care of defining O_ACCMODE accordingly. This is particularly important in order to keep our "open() can set errno to EISDIR" emulation working: it tests that (flags & O_ACCMODE) is not identical to O_RDONLY before going on to test specifically whether the file for which open() reported EACCES is, in fact, a directory.

See https://github.com/Microsoft/vcpkg On a first build, the vcpkg tools and the third party libraries are automatically downloaded and built. DLLs for the third party libraries are copied to the top-level (and t/helper) directory to facilitate debugging. See compat/vcbuild/README. A series of .bat files are invoked by the Makefile to find the location of the installed version of Visual Studio and the associated compiler tools (essentially replicating the environment setup performed by a "Developer Command Prompt"). This should find the most recent VS2015 or VS2017 installation. Output from these scripts are used by the Makefile to define compiler and linker pathnames and -I and -L arguments. The build produces .pdb files for both debug and release builds. Note: This commit was squashed from an organic series of commits developed between 2016 and 2018 in Git for Windows' `master` branch. This combined commit eliminates the obsolete commits related to fetching NuGet packages for third party libraries. It is difficult to use NuGet packages for C/C++ sources because they may be built by earlier versions of the MSVC compiler and have CRT version and linking issues. Additionally, the C/C++ NuGet packages that were using tended to not be updated concurrently with the sources. And in the case of cURL and OpenSSL, this could expose us to security issues.

However, when running the test suite, it is not so helpful, in particular when the debug assertions are then suppressed anyway because we disable the invalid parameter checking (via invalidcontinue.obj, see the comment in config.mak.uname about that object for more information). So let's simply disable that window in Debug Mode (it is already disabled in Release Mode).

Based on the generator for Visual Studio versions <= 2008 (which used .sln/.vcproj files), this patch copy-edits the generator of the .vcproj files to a new generator that produces .vcxproj files ready for Visual Studio 2010 and later (or MSBuild). As the vcpkg system (which is used to build Git's dependencies) cannot run in parallel (it does not lock, wreaking havoc with files being accessed and written at the same time, letting the vcpkg processes stumble over each others' toes), we make libgit the root of the project dependency tree and initialize the vcpkg system in this project's PreBuildEvent.

otherwise potential users would still have to download the entire Git for Windows SDK. So let's just add a target in the Makefile that can be used to generate said solution; The generated files will then be committed so that they can be pushed to a branch ready to check out by Visual Studio users. To make things even more useful, we also generate and commit other files that are required to run the test suite, such as templates and bin-wrappers: with this, developers can run the test suite in a regular Git Bash (that is part of a regular Git for Windows installation) after building the solution in Visual Studio.

A more sophisticated implementation may cache this data, e.g. for later reuse in calls to lstat. Make the dirent implementation pluggable so that it can be switched at runtime, e.g. based on a config option. Define a base DIR structure with pointers to readdir/closedir that match the opendir implementation (i.e. similar to vtable pointers in OOP). Define readdir/closedir so that they call the function pointers in the DIR structure. This allows to choose the opendir implementation on a call-by-call basis. Move the fixed sized dirent.d_name buffer to the dirent-specific DIR structure, as d_name may be implementation specific (e.g. a caching implementation may just set d_name to point into the cache instead of copying the entire file name string).

Windows operating system APIs seem to be much better at scanning the status of entire directories than checking single files. Add an lstat implementation that uses a cache for lstat data. Cache misses read the entire parent directory and add it to the cache. Subsequent lstat calls for the same directory are served directly from the cache. Also implement opendir / readdir / closedir so that they create and use directory listings in the cache. The cache doesn't track file system changes and doesn't plug into any modifying file APIs, so it has to be explicitly enabled for git functions that don't modify the working copy. Note: in an earlier version of this patch, the cache was always active and tracked file system changes via ReadDirectoryChangesW. However, this was much more complex and had negative impact on the performance of modifying git commands such as 'git checkout'.

With this patch, the bash will be executed through strace if the environment variable GIT_STRACE_COMMANDS is set, which comes in real handy when investigating issues in the test suite. Also support passing a path to a log file via GIT_STRACE_COMMANDS to force Git to call strace.exe with the `-o <path>` argument, i.e. to log into a file rather than print the log directly. That comes in handy when the output would otherwise misinterpreted by a calling process as part of Git's output. Note: the values "1", "yes" or "true" are *not* specifying paths, but tell Git to let strace.exe log directly to the console.

This limitation is also evident in Windows Explorer, cmd.exe and many other applications (including IDEs). Particularly annoying is that most Windows APIs return bogus error codes if a relative path only barely exceeds MAX_PATH in conjunction with the current directory, e.g. ERROR_PATH_NOT_FOUND / ENOENT instead of the infinitely more helpful ERROR_FILENAME_EXCED_RANGE / ENAMETOOLONG. Many Windows wide char APIs support longer than MAX_PATH paths through the file namespace prefix ('\\?\' or '\\?\UNC\') followed by an absolute path. Notable exceptions include functions dealing with executables and the current directory (CreateProcess, LoadLibrary, Get/SetCurrentDirectory) as well as the entire shell API (ShellExecute, SHGetSpecialFolderPath...). Introduce a handle_long_path function to check the length of a specified path properly (and fail with ENAMETOOLONG), and to optionally expand long paths using the '\\?\' file namespace prefix. Short paths will not be modified, so we don't need to worry about device names (NUL, CON, AUX). Contrary to MSDN docs, the GetFullPathNameW function doesn't seem to be limited to MAX_PATH (at least not on Win7), so we can use it to do the heavy lifting of the conversion (translate '/' to '\', eliminate '.' and '..', and make an absolute path). Add long path error checking to xutftowcs_path for APIs with hard MAX_PATH limit. Add a new MAX_LONG_PATH constant and xutftowcs_long_path function for APIs that support long paths. While improved error checking is always active, long paths support must be explicitly enabled via 'core.longpaths' option. This is to prevent end users to shoot themselves in the foot by checking out files that Windows Explorer, cmd/bash or their favorite IDE cannot handle. Test suite: Test the case is when the full pathname length of a dir is close to 260 (MAX_PATH).

The first and more obvious behavior is "Installer Detection", where Windows sometimes decides (by looking at things like the file name and even sequences of bytes within the executable) that an executable is an installer and should run elevated (causing the well-known popup dialog to appear). In Git's context, subcommands such as "git patch-id" or "git update-index" fall prey to this behavior. The second and more confusing behavior is "File Virtualization". It means that when files are written without having write permission, it does not fail (as expected), but they are instead redirected to somewhere else. When the files are read, the original contents are returned, though, not the ones that were just written somewhere else. Even more confusing, not all write accesses are redirected; Trying to write to write-protected .exe files, for example, will fail instead of redirecting. In addition to being unwanted behavior, File Virtualization causes dramatic slowdowns in Git (see for instance http://code.google.com/p/msysgit/issues/detail?id=320). There are two ways to prevent those two behaviors: Either you embed an application manifest within all your executables, or you add an external manifest (a file with the same name followed by .manifest) to all your executables. Since Git's builtins are hardlinked (or copied), it is simpler and more robust to embed a manifest. A recent enough MSVC compiler should already embed a working internal manifest, but for MinGW you have to do so by hand.

Gettext uses setlocale() to determine the output encoding for translated text, however, MSVCRT's setlocale() doesn't support UTF-8. As a result, translated text is encoded in system encoding (GetAPC()), and non-ASCII chars are mangled in console output. Use gettext's bind_textdomain_codeset() to force the encoding to UTF-8 on native Windows. In this developers' setup, HAVE_LIBCHARSET_H is apparently defined, but we *really* want to override the locale_charset() here.

However, this is not the case with terminal windows other than `cmd.exe`'s, e.g. with MSys2's own `mintty`. Non-cmd terminals such as `mintty` still have to have a Win32 Console to be proper console programs, but have to hide the Win32 Console to be able to provide more flexibility (such as being resizeable not only vertically but also horizontally). By writing to that Win32 Console, `git_terminal_prompt()` manages only to send the prompt to nowhere and to wait for input from a Console to which the user has no access. This commit introduces a function specifically to support `mintty` -- or other terminals that are compatible with MSys2's `/dev/tty` emulation. We use the `TERM` environment variable as an indicator for that: if the value starts with "xterm" (such as `mintty`'s "xterm_256color"), we prefer to let `xterm_prompt()` handle the user interaction. The most prominent user of `git_terminal_prompt()` is certainly `git-remote-https.exe`. It is an interesting use case because both `stdin` and `stdout` are redirected when Git calls said executable, yet it still wants to access the terminal. When running inside a `mintty`, the terminal is not accessible to the `git-remote-https.exe` program, though, because it is a MinGW program and the `mintty` terminal is not backed by a Win32 console. To solve that problem, we simply call out to the shell -- which is an *MSys2* program and can therefore access `/dev/tty`.

It also doesn't work for terminal emulators that hide the native console window (such as mintty), and 'TERM=xterm*' is not necessarily a reliable indicator for such terminals. The new shell_prompt() function, on the other hand, works fine for both MSys1 and MSys2, in native console windows as well as mintty, and properly supports Unicode. It just needs bash on the path (for 'read -s', which is bash-specific). On Windows, try to use the shell to read from the terminal. If that fails with ENOENT (i.e. bash was not found), use CONIN/OUT as fallback. Note: To test this, create a UTF-8 credential file with non-ASCII chars, e.g. in git-bash: 'echo url=http://täst.com > cred.txt'. Then in git-cmd, 'git credential fill <cred.txt' works (shell version), while calling git without the git-wrapper (i.e. 'mingw64\bin\git credential fill <cred.txt') mangles non-ASCII chars in both console output and input.

But GPG might fail, and send error messages to stderr. And we simply do not show them to the user. Even worse: this swallows any interactive prompt for a passphrase. And detaches stderr from the tty so that the passphrase cannot be read. So while the first problem could be fixed (by printing the captured stderr upon error), the second problem cannot be easily fixed, and presents a major regression. So let's just revert commit efee9553a4f97b2ecd8f49be19606dd4cf7d9c28.

An unintended side-effect is that "cold-calling" into the POSIX emulation will start with a locale based on the current code page, something that Git for Windows is very ill-prepared for, as it expects to be able to pass a command-line containing non-ASCII characters to the shell without having those characters munged. One symptom of this behavior: when `git clone` or `git fetch` shell out to call `git-upload-pack` with a path that contains non-ASCII characters, the shell tried to interpret the entire command-line (including command-line parameters) as executable path, which obviously must fail.

Implement stat by opening the file with as little permissions as possible and calling GetFileInformationByHandle on it. This way, all link resoltion is handled by the Windows file system layer. If symlinks are disabled, use lstat() as before, but fail with ELOOP if a symlink would have to be resolved.

However, currently there is no error handling whatsoever if FindFirstFile() fails. Call FindFirstFile() before modifying the stat *buf output parameter and error out if the call fails. Note: The FindFirstFile() return value includes all the data that we get from GetFileAttributesEx(), so we could replace GetFileAttributesEx() with FindFirstFile(). We don't do that because GetFileAttributesEx() is about twice as fast for single files. I.e. we only pay the extra cost of calling FindFirstFile() in the rare case that we encounter a reparse point. Note: The indentation of the remaining reparse point code will be fixed in the next patch.

Allow testing *with* symlink support by checking if native symlinks are enabled in MSys2 (via 'MSYS=winsymlinks:nativestrict'). Reminder: This would need to be changed if / when we find a way to run the test suite in a non-MSys-based shell (e.g. dash).

Symlinks of wrong type simply don't work. This even affects core Win32 APIs (e.g. DeleteFile() refuses to delete directory symlinks). However, CreateFile() with FILE_FLAG_BACKUP_SEMANTICS doesn't seem to care. Check the target type by first creating a tentative file symlink, opening it, and checking the type of the resulting handle. If it is a directory, recreate the symlink with the directory flag set. It is possible to create symlinks before the target exists (or in case of symlinks to symlinks: before the target type is known). If this happens, create a tentative file symlink and postpone the directory decision: keep a list of phantom symlinks to be processed whenever a new directory is created in mingw_mkdir(). Limitations: This algorithm may fail if a link target changes from file to directory or vice versa, or if the target directory is created in another process.

Previous Windows 10 versions will not understand that flag and return an ERROR_INVALID_PARAMETER, therefore we have to be careful to try passing that flag only when the build number indicates that it is supported. For more information about the new flag, see this blog post: https://blogs.windows.com/buildingapps/2016/12/02/symlinks-windows-10/ This patch is loosely based on the patch submitted by Samuel D. Leslie as https://github.com/git-for-windows/git/pull/1184.

If the type of symlink does not match its target, it doesn't work. Git does not record the type of symlink in the index or in a tree. On checkout it'll guess the type, which only works if the target exists at the time the symlink is created. This may often not be the case, for example when the link points at a directory inside a submodule. By specifying `symlink=file` or `symlink=dir` the user can specify what type of symlink Git should create, so Git doesn't have to rely on unreliable heuristics.

Earlier, libgit2 was nice enough to just re-use Git for Windows' C:\Program Files (x86)\Git\etc\gitconfig but with the upcoming Git for Windows 2.x, there would be more paths to search, as we will have 64-bit and 32-bit versions, and the corresponding config files will be in %PROGRAMFILES%\Git\mingw64\etc and ...\mingw32\etc, respectively. Worse: there are portable Git for Windows versions out there which live in totally unrelated directories, still. Therefore we came to a consensus to use `%PROGRAMDATA%\Git\config` as the location for shared Git settings that are of wider interest than just Git for Windows. Of course, the configuration in `%PROGRAMDATA%\Git\config` has the widest reach, therefore it must take the lowest precedence, i.e. Git for Windows can still override settings in its `etc/gitconfig` file.

This is a performance optimization. FSCACHE is a performance optimization available for Windows. It intercepts Posix-style lstat() calls into an in-memory directory using FindFirst/FindNext. It improves performance on Windows by catching the first lstat() call in a directory, using FindFirst/ FindNext to read the list of files (and attribute data) for the entire directory into the cache, and short-cut subsequent lstat() calls in the same directory. This gives a major performance boost on Windows. However, it does not remember "not found" directories. When STATUS runs and there are missing directories, the lstat() interception fails to find the parent directory and simply return ENOENT for the file -- it does not remember that the FindFirst on the directory failed. Thus subsequent lstat() calls in the same directory, each re-attempt the FindFirst. This completely defeats any performance gains. This can be seen by doing a sparse-checkout on a large repo and then doing a read-tree to reset the skip-worktree bits and then running status. This change reduced status times for my very large repo by 60%.

The current code in add_excludes() calls open() and then fstat() for a ".gitignore" file in each directory present in the worktree. Change that when fscache is enabled to call lstat() first and if present, call open(). This seems backwards because both lstat needs to do more work than fstat. But when fscache is enabled, fscache will already know if the .gitignore file exists and can completely avoid the IO calls. This works because of the lstat diversion to mingw_lstat when fscache is enabled. This reduced status times on a 350K file enlistment of the Windows repo on a NVMe SSD by 0.25 seconds.

During an "add", a call is made to run_diff_files() which calls check_remove() for each index-entry. This calls lstat(). On Windows, the fscache code intercepts the lstat() calls and builds a private cache using the FindFirst/FindNext routines, which are much faster. Somewhat independent of this, is the preload-index code which distributes some of the start-up costs across multiple threads. We need to keep the call to read_cache() before parsing the pathspecs (and hence cannot use the pathspecs to limit any preload) because parse_pathspec() is using the index to determine whether a pathspec is, in fact, in a submodule. If we would not read the index first, parse_pathspec() would not error out on a path that is inside a submodule, and t7400-submodule-basic.sh would fail with not ok 47 - do not add files from a submodule We still want the nice preload performance boost, though, so we simply call read_cache_preload(&pathspecs) after parsing the pathspecs.

Later when the ignore file was read, the buffer length did not match the stat.st_size field and we called die("cannot use <path> as an exclude file") Optimization Rationale ====================== The above optimization calls lstat() before open() primarily to ask fscache if the file exists. It gets the current stat-data as a side effect essentially for free (since we already have it in memory). If the file does not exist, it does not need to call open(). And since very few directories have .gitignore files, we can greatly reduce time spent in the filesystem. Discussion of Fix ================= The above optimization calls lstat() rather than stat() because the fscache only intercepts lstat() calls. Calls to stat() stay directed to the mingw_stat() completly bypassing fscache. Furthermore, calls to mingw_stat() always call {open, fstat, close} so that symlinks are properly dereferenced, which adds *additional* open/close calls on top of what the original code in dir.c is doing. Since the problem only manifests for symlinks, we add code to overwrite the stat-data when the path is a symlink. This preserves the effect of the performance gains provided by the fscache in the normal case.

Git for Windows introduced the `--no-lock-index` option a long time ago to fix that (it made it into Git for Windows v2.9.2(3)) by simply avoiding to write that file. The downside is that the periodic `git status` calls will be a little bit more wasteful because they may have to refresh the index repeatedly, only to throw away the updates when it exits. This cannot really be helped, though, as tools wanting to get a periodic update of the status have no way to predict when the user may want to lock the index herself. Sadly, a competing approach was submitted (by somebody who apparently has less work on their plate than this maintainer) that made it into v2.15.0 but is *different*: instead of a `git status`-only option, it is an option that comes *before* the Git command and is called differently, too. Let's give previous users a chance to upgrade to newer Git for Windows versions by handling the `--no-lock-index` option, still, though with a big fat warning.

This is a total waste of time and effort on a filesystem that orders data writes properly, but can be useful for filesystems that do not use journalling (traditional UNIX filesystems) or that only journal metadata and not file contents (OS X’s HFS+, or Linux ext3 with "data=writeback"). The most common file system on Windows (NTFS) does not guarantee that order, therefore a sudden loss of power (or any other event causing an unclean shutdown) would cause corrupt files (i.e. files filled with NULs). Therefore we need to change the default. Note that the documentation makes it sound as if this causes really bad performance. In reality, writing loose objects is something that is done only rarely, and only a handful of files at a time.

This is bad insofar as Git itself expects its signal handlers to run. A symptom is e.g. a left-behind .lock file that would not be left behind if the same operation was run, say, on Linux. To remedy this situation, we use an obscure trick: we inject a thread into the process that needs to be killed and to let that thread run the ExitProcess() function with the desired exit status. Thanks J Wyman for describing this trick. The advantage is that the ExitProcess() function lets the atexit handlers run. While this is still different from what Git expects (i.e. running a signal handler), in practice Git sets up signal handlers and atexit handlers that call the same code to clean up after itself. In case that the gentle method to terminate the process failed, we still fall back to calling TerminateProcess(), but in that case we now also make sure that processes spawned by the spawned process are terminated; TerminateProcess() does not give the spawned process a chance to do so itself. Please note that this change only affects how Git for Windows tries to terminate processes spawned by Git's own executables. Third-party software that *calls* Git and wants to terminate it *still* need to make sure to imitate this gentle method, otherwise this patch will not have any effect.

Even if this value is not documented anywhere, CreateProcess() seems to work fine without complaints if hStdInput set to this value. In contrast, the upcoming code to restrict which file handles get inherited by spawned processes would result in `ERROR_INVALID_PARAMETER` when including such handle values in the list. To help this, special-case the value (HANDLE)-2 returned by _get_osfhandle() and replace it with INVALID_HANDLE_VALUE, which will hopefully let the handle inheritance restriction work even when called from TortoiseGit.

Which we do need to set because we need to pass in stdin/stdout/stderr to talk to the child processes. Sadly, this means that all file handles (unless marked via O_NOINHERIT) are inherited. This lead to problems in GVFS Git, where a long-running read-object hook is used to hydrate missing objects, and depending on the circumstances, might only be called *after* Git opened a file handle. Ideally, we would not open files without O_NOINHERIT unless *really* necessary (i.e. when we want to pass the opened file handle as standard handle into a child process), but apparently it is all-too-easy to introduce incorrect open() calls: this happened, and prevented updating a file after the read-object hook was started because the hook still held a handle on said file. Happily, there is a solution: as described in the "Old New Thing" https://blogs.msdn.microsoft.com/oldnewthing/20111216-00/?p=8873 there is a way, starting with Windows Vista, that lets us define precisely which handles should be inherited by the child process. And since we bumped the minimum Windows version for use with Git for Windows to Vista with v2.10.1 (i.e. a *long* time ago), we can use this method. So let's do exactly that. We need to make sure that the list of handles to inherit does not contain duplicates; Otherwise CreateProcessW() would fail with ERROR_INVALID_ARGUMENT. While at it, stop setting errno to ENOENT unless it really is the correct value. Also, fall back to not limiting handle inheritance under certain error conditions (e.g. on Windows 7, which is a lot stricter in what handles you can specify to limit to).

And similar to Git's builtins, the applets can be called via `busybox <command>`, or the BusyBox executable can be copied/hard-linked to the command name. The similarities do not end here. Just as with Git's builtins, it is problematic that BusyBox' hard-linked applets cannot easily be put into a .zip file: .zip archives have no concept of hard-links and therefore would store identical copies (and also extract identical copies, "inflating" the archive unnecessarily). To counteract that issue, MinGit already ships without hard-linked copies of the builtins, and the plan is to do the same with BusyBox' applets: simply ship busybox.exe as single executable, without hard-linked applets. To accommodate that, Git is being taught by this commit a very special trick, exploiting the fact that it is possible to call an executable with a command-line whose argv[0] is different from the executable's name: when `sh` is to be spawned, and no `sh` is found in the PATH, but busybox.exe is, use that executable (with unchanged argv). Likewise, if any executable to be spawned is not on the PATH, but busybox.exe is found, parse the output of `busybox.exe --help` to find out what applets are included, and if the command matches an included applet name, use busybox.exe to execute it.

This helps e.g. when trying to verify a Git for Windows installation without requiring to download a full Git for Windows SDK (which would use up 600+ megabytes of bandwidth, and over a gigabyte of disk space). Of course, it still requires the test helpers to be build *somewhere*, and the Git version should at least roughly match the version from which the test suite comes. At the same time, this new way to run the test suite allows to validate that a BusyBox-backed MinGit works as expected (verifying that BusyBox' functionality is enough to at least pass the test suite).

However, that limits esoteric test scenarios such as Git for Windows', where an end user installation has to ship with `iconv` for the sole purpose of being testable. That payload serves no other purpose. So let's just have a test helper (to be able to test Git, the test helpers have to be available, after all) to act as `iconv` replacement.

That also means that it does *not* use the Unix convention of separating the entries in the PATH variable using colons, but semicolons. However, there are also BusyBox ports to Windows which use a POSIX emulation layer such as Cygwin's or MSYS2's runtime, i.e. using colons as PATH separators. As a tell-tale, let's use the presence of semicolons in the PATH variable: on Unix, it is highly unlikely that it contains semicolons, and on Windows (without POSIX emulation), it is virtually guaranteed, as everybody should have both $SYSTEMROOT and $SYSTEMROOT/system32 in their PATH.

We already excluded test cases using such files from running on Windows when git.exe itself was tested. However, we still had two test cases that try to create such a file, and redirect stdin from such a file, respectively. This *seems* to work in Git for Windows' Bash due to an obscure feature inherited from Cygwin: illegal filename characters are simply mapped into/from a private UTF-8 page. Pure Win32 programs (such as git.exe) *still* cannot work with those files, of course, but at least Unix shell scripts pretend to be able to. This entire strategy breaks down when switching to any Unix shell lacking support for that private UTF-8 page trick, e.g. BusyBox-w32's ash. So let's just exclude test cases that test whether the Unix shell can redirect to/from files with "funny names" those from running on Windows, too.

This mode is so out of fashion in the meantime, though, that e.g. BusyBox' diff decided not even to bother to support it. It only supports unified diffs. So let's just switch away from "normal" diffs and use unified diffs, as we really are only interested in the `+` lines.

There *are* some more native ports of Unix shells out there, though, most notably BusyBox-w32's ash. These native ports do not use any POSIX emulation layer (or at most a *very* thin one, choosing to avoid features such as fork() that are expensive to emulate on Windows), and they use native Windows paths (usually with forward slashes instead of backslashes, which is perfectly legal in almost all use cases). And here comes the problem: with a $PWD looking like, say, C:/git-sdk-64/usr/src/git/t/trash directory.t5813-proto-disable-ssh Git's test scripts get quite a bit confused, as their assumptions have been shattered. Not only does this path contain a colon (oh no!), it also does not start with a slash. This is a problem e.g. when constructing a URL as t5813 does it: ssh://remote$PWD. Not only is it impossible to separate the "host" from the path with a $PWD as above, even prefixing $PWD by a slash won't work, as /C:/git-sdk-64/... is not a valid path. As a workaround, detect when $PWD does not start with a slash on Windows, and simply strip the drive prefix, using an obscure feature of Windows paths: if an absolute Windows path starts with a slash, it is implicitly prefixed by the drive prefix of the current directory. As we are talking about the current directory here, anyway, that strategy works.

This has not been a problem so far because Git for Windows uses MSYS2's Bash using a POSIX emulation layer that also pretends that the current directory is a Unix path (at least as long as we're in a shell script). However, that is rather limiting, as Git for Windows also explores other ports of other Unix shells. One of those is BusyBox-w32's ash, which is a native port (i.e. *not* using any POSIX emulation layer, and certainly not emulating Unix paths).

If you have an open-source +mindset and want to start contributing to Git, but primarily use a Windows machine, then you may +have trouble getting started. This guide is for you. + +Get the Source +-------------- + +Clone the [GitForWindows repository on GitHub](https://github.com/git-for-windows/git). +It is helpful to create your own fork for storing your development branches. + +Windows uses different line endings than Unix systems. See +[this GitHub article on working with line endings](https://help.github.com/articles/dealing-with-line-endings/#refreshing-a-repository-after-changing-line-endings) +if you have trouble with line endings. + +Build the Source +---------------- + +First, download and install the latest [Git for Windows SDK (64-bit)](https://github.com/git-for-windows/build-extra/releases/latest). +When complete, you can run the Git SDK, which creates a new Git Bash terminal window with +the additional development commands, such as `make`. + + As of time of writing, the SDK uses a different credential manager, so you may still want to use normal Git + Bash for interacting with your remotes. Alternatively, use SSH rather than HTTPS and + avoid credential manager problems. + +You should now be ready to type `make` from the root of your `git` source directory. +Here are some helpful variations: + +* `make -j[N] DEVELOPER=1`: Compile new sources using up to N concurrent processes. + The `DEVELOPER` flag turns on all warnings; code failing these warnings will not be + accepted upstream ("upstream" = "the core Git project"). +* `make clean`: Delete all compiled files. + +When running `make`, you can use `-j$(nproc)` to automatically use the number of processors +on your machine as the number of concurrent build processes. + +You can go deeper on the Windows-specific build process by reading the +[technical overview](https://github.com/git-for-windows/git/wiki/Technical-overview) or the +[guide to compiling Git with Visual Studio](https://github.com/git-for-windows/git/wiki/Compiling-Git-with-Visual-Studio). + +## Building `git` on Windows with Visual Studio + +The typical approach to building `git` is to use the standard `Makefile` with GCC, as +above. Developers working in a Windows environment may want to instead build with the +[Microsoft Visual C++ compiler and libraries toolset (MSVC)](https://blogs.msdn.microsoft.com/vcblog/2017/03/07/msvc-the-best-choice-for-windows/). +There are a few benefits to using MSVC over GCC during your development, including creating +symbols for debugging and [performance tracing](https://github.com/Microsoft/perfview#perfview-overview). + +There are two ways to build Git for Windows using MSVC. Each have their own merits. + +### Using SDK Command Line + +Use one of the following commands from the SDK Bash window to build Git for Windows: + +``` + make MSVC=1 -j12 + make MSVC=1 DEBUG=1 -j12 +``` + +The first form produces release-mode binaries; the second produces debug-mode binaries. +Both forms produce PDB files and can be debugged. However, the first is best for perf +tracing and the second is best for single-stepping. + +You can then open Visual Studio and select File -> Open -> Project/Solution and select +the compiled `git.exe` file. This creates a basic solution and you can use the debugging +and performance tracing tools in Visual Studio to monitor a Git process. Use the Debug +Properties page to set the working directory and command line arguments. + +Be sure to clean up before switching back to GCC (or to switch between debug and +release MSVC builds): + +``` + make MSVC=1 -j12 clean + make MSVC=1 DEBUG=1 -j12 clean +``` + +### Using `vs/master` Solution + +If you prefer working in Visual Studio with a solution full of projects, then there is a +branch in Git for Windows called [`vs/master`](https://github.com/git-for-windows/git/branches). +This branch is kept up-to-date with the `master` branch, except it has one more commit that +contains the solution and project files. Read [the wiki page on this approach](https://github.com/git-for-windows/git/wiki/Compiling-Git-with-Visual-Studio) for more information. + +I want to make a small warning before you start working on the `vs/master` branch. If you +create a new topic branch based on `vs/master`, you will need to rebase onto `master` before +you can submit a pull request. The commit at the tip of `vs/master` is not intended to ever +become part of the `master` branch. If you created a branch, `myTopic` based on `vs/master`, +then use the following rebase command to move it onto the `master` branch: + +``` +git rebase --onto master vs/master myTopic +``` + +What to Change? +--------------- + +Many new contributors ask: What should I start working on? + +One way to win big with the open-source community is to look at the +[issues page](https://github.com/git-for-windows/git/issues) and see if there are any issues that +you can fix quickly, or if anything catches your eye. + +You can also look at [the unofficial Chromium issues page](https://crbug.com/git) for +multi-platform issues. You can look at recent user questions on +[the Git mailing list](https://public-inbox.org/git). + +Or you can "scratch your own itch", i.e. address an issue you have with Git. The team at Microsoft where the Git for Windows maintainer works, for example, is focused almost entirely on [improving performance](https://blogs.msdn.microsoft.com/devops/2018/01/11/microsofts-performance-contributions-to-git-in-2017/). +We approach our work by finding something that is slow and try to speed it up. We start our +investigation by reliably reproducing the slow behavior, then running that example using +the MSVC build and tracing the results in PerfView. + +You could also think of something you wish Git could do, and make it do that thing! The +only concern I would have with this approach is whether or not that feature is something +the community also wants. If this excites you though, go for it! Don't be afraid to +[get involved in the mailing list](http://vger.kernel.org/vger-lists.html#git) early for +feedback on the idea. + +Test Your Changes +----------------- + +After you make your changes, it is important that you test your changes. Manual testing is +important, but checking and extending the existing test suite is even more important. You +want to run the functional tests to see if you broke something else during your change, and +you want to extend the functional tests to be sure no one breaks your feature in the future. + +### Functional Tests + +Navigate to the `t/` directory and type `make` to run all tests or use `prove` as +[described in the Git for Windows wiki](https://github.com/git-for-windows/git/wiki/Building-Git): + +``` +prove -j12 --state=failed,save ./t[0-9]*.sh +``` + +You can also run each test directly by running the corresponding shell script with a name +like `tNNNN-descriptor.sh`. + +If you are adding new functionality, you may need to create unit tests by creating +helper commands that test a very limited action. These commands are stored in `t/helpers`. +When adding a helper, be sure to add a line to `t/Makefile` and to the `.gitignore` for the +binary file you add. The Git community prefers functional tests using the full `git` +executable, so try to exercise your new code using `git` commands before creating a test +helper. + +To find out why a test failed, repeat the test with the `-x -v -d -i` options and then +navigate to the appropriate "trash" directory to see the data shape that was used for the +test failed step. + +Read [`t/README`](t/README) for more details. + +### Performance Tests + +If you are working on improving performance, you will need to be acquainted with the +performance tests in `t/perf`. There are not too many performance tests yet, but adding one +as your first commit in a patch series helps to communicate the boost your change provides. + +To check the change in performance across multiple versions of `git`, you can use the +`t/perf/run` script. For example, to compare the performance of `git rev-list` across the +`core/master` and `core/next` branches compared to a `topic` branch, you can run + +``` +cd t/perf +./run core/master core/next topic -- p0001-rev-list.sh +``` + +You can also set certain environment variables to help test the performance on different +repositories or with more repetitions. The full list is available in +[the `t/perf/README` file](t/perf/README), +but here are a few important ones: + +``` +GIT_PERF_REPO=/path/to/repo +GIT_PERF_LARGE_REPO=/path/to/large/repo +GIT_PERF_REPEAT_COUNT=10 +``` + +When running the performance tests on Linux, you may see a message "Can't locate JSON.pm in +@INC" and that means you need to run `sudo cpanm install JSON` to get the JSON perl package. + +For running performance tests, it can be helpful to set up a few repositories with strange +data shapes, such as: + +**Many objects:** Clone repos such as [Kotlin](https://github.com/jetbrains/kotlin), [Linux](https://github.com/torvalds/linux), or [Android](https://source.android.com/setup/downloading). + +**Many pack-files:** You can split a fresh clone into multiple pack-files of size at most +16MB by running `git repack -adfF --max-pack-size=16m`. See the +[`git repack` documentation](https://git-scm.com/docs/git-repack) for more information. +You can count the number of pack-files using `ls .git/objects/pack/*.pack | wc -l`. + +**Many loose objects:** If you already split your repository into multiple pack-files, then +you can pick one to split into loose objects using `cat .git/objects/pack/[id].pack | git unpack-objects`; +delete the `[id].pack` and `[id].idx` files after this. You can count the number of loose +bjects using `ls .git/objects/??/* | wc -l`. + +**Deep history:** Usually large repositories also have deep histories, but you can use the +[test-many-commits-1m repo](https://github.com/cirosantilli/test-many-commits-1m/) to +target deep histories without the overhead of many objects. One issue with this repository: +there are no merge commits, so you will need to use a different repository to test a "wide" +commit history. + +**Large Index:** You can generate a large index and repo by using the scripts in +`t/perf/repos`. There are two scripts. `many-files.sh` which will generate a repo with +same tree and blobs but different paths. Using `many-files.sh -d 5 -w 10 -f 9` will create +a repo with ~1 million entries in the index. `inflate-repo.sh` will use an existing repo +and copy the current work tree until it is a specified size. + +Test Your Changes on Linux +-------------------------- + +It can be important to work directly on the [core Git codebase](https://github.com/git/git), +such as a recent commit into the `master` or `next` branch that has not been incorporated +into Git for Windows. Also, it can help to run functional and performance tests on your +code in Linux before submitting patches to the mailing list, which focuses on many platforms. +The differences between Windows and Linux are usually enough to catch most cross-platform +issues. + +### Using the Windows Subsystem for Linux + +The [Windows Subsystem for Linux (WSL)](https://docs.microsoft.com/en-us/windows/wsl/install-win10) +allows you to [install Ubuntu Linux as an app](https://www.microsoft.com/en-us/store/p/ubuntu/9nblggh4msv6) +that can run Linux executables on top of the Windows kernel. Internally, +Linux syscalls are interpreted by the WSL, everything else is plain Ubuntu. + +First, open WSL (either type "Bash" in Cortana, or execute "bash.exe" in a CMD window). +Then install the prerequisites, and `git` for the initial clone: + +``` +sudo apt-get update +sudo apt-get install git gcc make libssl-dev libcurl4-openssl-dev \ + libexpat-dev tcl tk gettext git-email zlib1g-dev +``` + +Then, clone and build: + +``` +git clone https://github.com/git-for-windows/git +cd git +git remote add -f upstream https://github.com/git/git +make +``` + +Be sure to clone into `/home/[user]/` and not into any folder under `/mnt/?/` or your build +will fail due to colons in file names. + +### Using a Linux Virtual Machine with Hyper-V + +If you prefer, you can use a virtual machine (VM) to run Linux and test your changes in the +full environment. The test suite runs a lot faster on Linux than on Windows or with the WSL. +You can connect to the VM using an SSH terminal like +[PuTTY](https://www.chiark.greenend.org.uk/~sgtatham/putty/). + +The following instructions are for using Hyper-V, which is available in some versions of Windows. +There are many virtual machine alternatives available, if you do not have such a version installed. + +* [Download an Ubuntu Server ISO](https://www.ubuntu.com/download/server). +* Open [Hyper-V Manager](https://docs.microsoft.com/en-us/virtualization/hyper-v-on-windows/quick-start/enable-hyper-v). +* [Set up a virtual switch](https://docs.microsoft.com/en-us/virtualization/hyper-v-on-windows/quick-start/connect-to-network) + so your VM can reach the network. +* Select "Quick Create", name your machine, select the ISO as installation source, and un-check + "This virtual machine will run Windows." +* Go through the Ubuntu install process, being sure to select to install OpenSSH Server. +* When install is complete, log in and check the SSH server status with `sudo service ssh status`. + * If the service is not found, install with `sudo apt-get install openssh-server`. + * If the service is not running, then use `sudo service ssh start`. +* Use `shutdown -h now` to shutdown the VM, go to the Hyper-V settings for the VM, expand Network Adapter + to select "Advanced Features", and set the MAC address to be static (this can save your VM from losing + network if shut down incorrectly). +* Provide as many cores to your VM as you can (for parallel builds). +* Restart your VM, but do not connect. +* Use `ssh` in Git Bash, download [PuTTY](http://www.putty.org/), or use your favorite SSH client to connect to the VM through SSH. + +In order to build and use `git`, you will need the following libraries via `apt-get`: + +``` +sudo apt-get update +sudo apt-get install git gcc make libssl-dev libcurl4-openssl-dev \ + libexpat-dev tcl tk gettext git-email zlib1g-dev +``` + +To get your code from your Windows machine to the Linux VM, it is easiest to push the branch to your fork of Git and clone your fork in the Linux VM. + +Don't forget to set your `git` config with your preferred name, email, and editor. + +Polish Your Commits +------------------- + +Before submitting your patch, be sure to read the [coding guidelines](https://github.com/git/git/blob/master/Documentation/CodingGuidelines) +and check your code to match as best you can. This can be a lot of effort, but it saves +time during review to avoid style issues. + +The other possibly major difference between the mailing list submissions and GitHub PR workflows +is that each commit will be reviewed independently. Even if you are submitting a +patch series with multiple commits, each commit must stand on it's own and be reviewable +by itself. Make sure the commit message clearly explain the why of the commit not the how. +Describe what is wrong with the current code and how your changes have made the code better. + +When preparing your patch, it is important to put yourself in the shoes of the Git community. +Accepting a patch requires more justification than approving a pull request from someone on +your team. The community has a stable product and is responsible for keeping it stable. If +you introduce a bug, then they cannot count on you being around to fix it. When you decided +to start work on a new feature, they were not part of the design discussion and may not +even believe the feature is worth introducing. + +Questions to answer in your patch message (and commit messages) may include: +* Why is this patch necessary? +* How does the current behavior cause pain for users? +* What kinds of repositories are necessary for noticing a difference? +* What design options did you consider before writing this version? Do you have links to + code for those alternate designs? +* Is this a performance fix? Provide clear performance numbers for various well-known repos. + +Here are some other tips that we use when cleaning up our commits: + +* Commit messages should be wrapped at 76 columns per line (or less; 72 is also a + common choice). +* Make sure the commits are signed off using `git commit (-s|--signoff)`. See + [SubmittingPatches](https://github.com/git/git/blob/v2.8.1/Documentation/SubmittingPatches#L234-L286) + for more details about what this sign-off means. +* Check for whitespace errors using `git diff --check [base]...HEAD` or `git log --check`. +* Run `git rebase --whitespace=fix` to correct upstream issues with whitespace. +* Become familiar with interactive rebase (`git rebase -i`) because you will be reordering, + squashing, and editing commits as your patch or series of patches is reviewed. +* Make sure any shell scripts that you add have the executable bit set on them. This is + usually for test files that you add in the `/t` directory. You can use + `git add --chmod=+x [file]` to update it. You can test whether a file is marked as executable + using `git ls-files --stage \*.sh`; the first number is 100755 for executable files. +* Your commit titles should match the "area: change description" format. Rules of thumb: + * Choose "<area>: " prefix appropriately. + * Keep the description short and to the point. + * The word that follows the "<area>: " prefix is not capitalized. + * Do not include a full-stop at the end of the title. + * Read a few commit messages -- using `git log origin/master`, for instance -- to + become acquainted with the preferred commit message style. +* Build source using `make DEVELOPER=1` for extra-strict compiler warnings. + +Submit Your Patch +----------------- + +Git for Windows [accepts pull requests on GitHub](https://github.com/git-for-windows/git/pulls), but +these are reserved for Windows-specific improvements. For core Git, submissions are accepted on +[the Git mailing list](https://public-inbox.org/git). + +### Configure Git to Send Emails + +There are a bunch of options for configuring the `git send-email` command.

There are three important options: + +* `--cover-letter`: If specified, create a `[v#-]0000-cover-letter.patch` file that can be + edited to describe the patch as a whole. If you previously added a branch description using + `git branch --edit-description`, you will end up with a 0/N mail with that description and + a nice overall diffstat. +* `--in-reply-to=[Message-ID]`: This will mark your cover letter as replying to the given + message (which should correspond to your previous iteration). To determine the correct Message-ID, + find the message you are replying to on [public-inbox.org/git](https://public-inbox.org/git) and take + the ID from between the angle brackets. + +* `--subject-prefix=[prefix]`: This defaults to [PATCH]. For subsequent iterations, you will want to + override it like `--subject-prefix="[PATCH v2]"`. You can also use the `-v` option to have it + automatically generate the version number in the patches. + +If you have multiple commits and use the `--cover-letter` option be sure to open the +`0000-cover-letter.patch` file to update the subject and add some details about the overall purpose +of the patch series. + +### Examples + +To generate a single commit patch file: +``` +git format-patch -s -o [dir] -1 +``` +To generate four patch files from the last three commits with a cover letter: +``` +git format-patch --cover-letter -s -o [dir] HEAD~4 +``` +To generate version 3 with four patch files from the last four commits with a cover letter: +``` +git format-patch --cover-letter -s -o [dir] -v 3 HEAD~4 +``` + +### Submit the Patch + +Run [`git send-email`](https://git-scm.com/docs/git-send-email), starting with a test email: + +``` +git send-email --to=yourself@address.com [dir with patches]/*.patch +``` + +After checking the receipt of your test email, you can send to the list and to any +potentially interested reviewers. + +``` +git send-email --to=git@vger.kernel.org --cc=<email1> --cc=<email2> [dir with patches]/*.patch +``` + +To submit a nth version patch (say version 3): + +``` +git send-email --to=git@vger.kernel.org --cc=<email1> --cc=<email2> \ + --in-reply-to=<the message id of cover letter of patch v2> [dir with patches]/*.patch +``` From aa22454da26b0ce4f1fe20ccd3c069d2111ed24a Mon Sep 17 00:00:00 2001 From: Johannes Schindelin <johannes.schindelin@gmx.de> Date: Fri, 10 Jan 2014 16:16:03 -0600 Subject: [PATCH 763/812] README.md: Add a Windows-specific preamble Includes touch-ups by Philip Oakley.

Converting all at once proved hard to review, so starting with just apply lets conversion get started without the other commands being finished. The helper is being implemented as a drop in replacement for stash so that when it is complete it can simply be renamed and the shell script deleted. Delete the contents of the apply_stash shell function and replace it with a call to stash--helper apply until pop is also converted.

In order to do that, `create` and `push` were adapted to work without `stash.sh`. For example, before this commit, `git stash create` called `git stash--helper create --message "$*"`. If it called `git stash--helper create "$@"`, then some of these changes wouldn't have been necessary. This commit also removes the word `helper` since now stash is called directly and not by a shell script.

For example, `git stash push -u` would call at some points the following functions: * `check_changes()` (inside `do_push_stash()`) * `do_create_stash()`, which calls: `check_changes()` and `get_untracked_files()` Note that `check_changes()` also calls `get_untracked_files()`. So, `check_changes()` is called 2 times and `get_untracked_files()` 3 times. The old function `check_changes()` now consists of two functions: `get_untracked_files()` and `check_changes_tracked_files()`. These are the call chains for `push` and `create`: * `push_stash()` -> `do_push_stash()` -> `do_create_stash()` * `create_stash()` -> `do_create_stash()` To prevent calling the same functions over and over again, `check_changes()` inside `do_create_stash()` is now placed in the caller functions (`create_stash()` and `do_push_stash()`). This way `check_changes()` and `get_untracked files()` are called only one time. https://public-inbox.org/git/20180818223329.GJ11326@hank.intra.tgummerer.com/ Signed-off-by: Paul-Sebastian Ungureanu <ungureanupaulsebastian@gmail.com> --- builtin/stash.c | 52 ++++++++++++++++++++++++++++--------------------- 1 file changed, 30 insertions(+), 22 deletions(-) diff --git a/builtin/stash.c b/builtin/stash.c index 9bef5ddc4b..79275b995d 100644 --- a/builtin/stash.c +++ b/builtin/stash.c @@ -879,18 +879,18 @@ static int get_untracked_files(struct pathspec ps, int include_untracked, } /* - * The return value of `check_changes()` can be: + * The return value of `check_changes_tracked_files()` can be: * * < 0 if there was an error * = 0 if there are no changes. * > 0 if there are changes. */ -static int check_changes(struct pathspec ps, int include_untracked) + +static int check_changes_tracked_files(struct pathspec ps) { int result; struct rev_info rev; struct object_id dummy; - struct strbuf out = STRBUF_INIT; /* No initial commit. */ if (get_oid("HEAD", &dummy)) @@ -918,16 +918,28 @@ static int check_changes(struct pathspec ps, int include_untracked) if (diff_result_code(&rev.diffopt, result)) return 1; - if (include_untracked && get_untracked_files(ps, include_untracked, - &out)) { - strbuf_release(&out); - return 1; - } - - strbuf_release(&out); return 0; } +/* + * The function will fill `untracked_files` with the names of untracked files + * It will return 1 if there were any changes and 0 if there were not. + */ + +static int check_changes(struct pathspec ps, int include_untracked, + struct strbuf *untracked_files) +{ + int ret = 0; + if (check_changes_tracked_files(ps)) + ret = 1; + + if (include_untracked && get_untracked_files(ps, include_untracked, + untracked_files)) + ret = 1; + + return ret; +} + static int save_untracked_files(struct stash_info *info, struct strbuf *msg, struct strbuf files) { @@ -1134,7 +1146,7 @@ static int do_create_stash(struct pathspec ps, struct strbuf *stash_msg_buf, head_commit = lookup_commit(the_repository, &info->b_commit); } - if (!check_changes(ps, include_untracked)) { + if (!check_changes(ps, include_untracked, &untracked_files)) { ret = 1; goto done; } @@ -1159,8 +1171,7 @@ static int do_create_stash(struct pathspec ps, struct strbuf *stash_msg_buf, goto done; } - if (include_untracked && get_untracked_files(ps, include_untracked, - &untracked_files)) { + if (include_untracked) { if (save_untracked_files(info, &msg, untracked_files)) { if (!quiet) fprintf_ln(stderr, _("Cannot save " @@ -1241,18 +1252,14 @@ static int create_stash(int argc, const char **argv, const char *prefix) strbuf_join_argv(&stash_msg_buf, argc - 1, ++argv, ' '); memset(&ps, 0, sizeof(ps)); - ret = do_create_stash(ps, &stash_msg_buf, 0, 0, &info, NULL, 0); + if (!check_changes_tracked_files(ps)) + return 0; - if (!ret) + if (!(ret = do_create_stash(ps, &stash_msg_buf, 0, 0, &info, NULL, 0))) printf_ln("%s", oid_to_hex(&info.w_commit)); strbuf_release(&stash_msg_buf); - - /* - * ret can be 1 if there were no changes.

Just like we have `rebase.useBuiltin` to fall back to the scripted rebase, to give end users a way out when they discover a bug in the builtin command, this commit adds support for `stash.useBuiltin`. This is necessary because Git for Windows wants to ship the builtin stash earlier than core Git: Git for Windows v2.19.0 will come with the option of a drastically faster (if a lot less battle-tested) `git stash`. As the file name `git-stash` is already in use, let's rename the scripted backend to `git-legacy-stash`. To make the test suite pass with `stash.useBuiltin=false`, this commit also backports rudimentary support for `-q` (but only *just* enough to appease the test suite), and adds a super-ugly hack to force exit code 129 for `git stash -h`.

The former has a safety valve allowing to fall back to the scripted `rebase`, just in case that there is a bug in the builtin `rebase`: setting the config variable `rebase.useBuiltin` to `false` will fall back to using the scripted version. The latter did not have such a safety hatch. Let's reinstate the scripted interactive rebase backend so that `rebase.useBuiltin=false` will not use the builtin interactive rebase, just in case that an end user runs into a bug with the builtin version and needs to get out of the fix really quickly. This is necessary because Git for Windows wants to ship the builtin rebase/interactive rebase earlier than core Git: Git for Windows v2.19.0 will come with the option of a drastically faster (if a lot less battle-tested) `git rebase`/`git rebase -i`. As the file name `git-rebase--interactive` is already in use, let's rename the scripted backend to `git-legacy-rebase--interactive`. A couple of additional touch-ups are needed (such as teaching the builtin `rebase--interactive`, which assumed the role of the `rebase--helper`, to perform the two tricks to skip the unnecessary picks and to generate a new todo list) to make things work again.

This puts requirements on it to be thread safe so that callers like preload-index can call it from multiple threads. This was implemented with a single mutex and completion events which introduces contention between the calling threads. Simplify the threading model by making fscache thread specific. This allows us to remove the global mutex and synchronization events entirely and instead associate a fscache with every thread that requests one. This works well with the current multi-threading which divides the cache entries into blocks with a separate thread processing each block. At the end of each worker thread, if there is a fscache on the primary thread, merge the cached results from the worker into the primary thread cache. This enables us to reuse the cache later especially when scanning for untracked files. In testing, this reduced the time spent in preload_index() by about 25% and also reduced the CPU utilization significantly. On a repo with ~200K files, it reduced overall status times by ~12%.

To help debugging such things, we introduce the `open_in_gdb()` function which can be called at a code location where the segfault happens (or as close as one can get); This will open a new MinTTY window with a GDB that already attached to the current process.

Update fscache to call the underlying kernel API NtQueryDirectoryFile so that we can do the buffer management ourselves. That allows us to allocate a single buffer for the lifetime of the cache and reuse it for each directory. This change improves performance of 'git status' by 18% in a repo with ~200K files and 30k folders. Documentation for NtQueryDirectoryFile can be found at: https://docs.microsoft.com/en-us/windows-hardware/drivers/ddi/content/ntifs/nf-ntifs-ntquerydirectoryfile https://docs.microsoft.com/en-us/windows/desktop/FileIO/file-attribute-constants https://docs.microsoft.com/en-us/windows/desktop/fileio/reparse-point-tags To determine if the specified directory is a symbolic link, inspect the FileAttributes member to see if the FILE_ATTRIBUTE_REPARSE_POINT flag is set. If so, EaSize will contain the reparse tag (this is a so far undocumented feature, but confirmed by the NTFS developers). To determine if the reparse point is a symbolic link (and not some other form of reparse point), test whether the tag value equals the value IO_REPARSE_TAG_SYMLINK.
