From a8107652bc4f2a62bccee627c25eb8b5beef5218 Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Fri, 26 Jan 2018 16:34:59 +0100 Subject: [PATCH 01/32] mingw: demonstrate that all file handles are inherited by child processes When spawning child processes, we really should be careful which file handles we let them inherit. This is doubly important on Windows, where we cannot rename, delete, or modify files if there is still a file handle open. Sadly, we have to guard this test inside #ifdef WIN32: we need to use the value of the HANDLE directly, and that concept does not exist on Linux/Unix.

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 `, 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 patch does not fix this problem by any stretch of imagination. However, it fixes *the* Perl invocation that *every single* test script has to run. While at it, it makes the source code also more grep'able, as the code that unsets some, but not all, GIT_* environment variables just became a *lot* more explicit. And all that while still reducing the total number of lines.

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.

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). So let's just detect if there is a colon in $PWD and punt in that case.
