From 45106a68ad1e09859be8c5bdd8c8d14440aae38a Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Tue, 10 Jan 2017 23:30:13 +0100 Subject: [PATCH 01/99] 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. But I changed lookup_prog to use _waccess directly so that we only convert the path to UTF-16 once.

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.

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.

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 --- 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 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 $status + fi + junit_insert="" junit_insert="$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" " $junit_insert" fi @@ -787,6 +815,10 @@ test_start_ () { if test -n "$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 Date: Fri, 31 Aug 2018 16:26:32 +0200 Subject: [PATCH 43/99] 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.

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'.

Only one of the results is added to the cache, all others are leaked. This wastes performance and memory. 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. When the first thread has loaded the directory, it replaces the future object with the result and notifies waiting threads.

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).
