From 4cacd5b1ebfb540c373114ab2af6484b1d8a7462 Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Thu, 20 Jul 2017 22:45:01 +0200 Subject: [PATCH 01/21] mingw: explicitly specify with which cmd to prefix the cmdline The main idea of this patch is that even if we have to look up the absolute path of the script, if only the basename was specified as argv[0], then we should use that basename on the command line, too, not the absolute path. This patch will also help with the upcoming patch where we automatically substitute "sh ..." by "busybox sh ..." if "sh" is not in the PATH but "busybox" is: we will do that by substituting the actual executable, but still keep prepending "sh" to the command line.

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.

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.

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.

Our From 151d309269ce6c2102abab8eaba20bb4538872af Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Fri, 7 Jul 2017 10:15:36 +0200 Subject: [PATCH 20/21] t9200: skip tests when $PWD contains a colon On Windows, the current working directory is pretty much guaranteed to contain a colon. 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.

Sadly, Git's test suite still relies on a Perl interpreter even if compiled with NO_PERL=YesPlease. We punt for now, installing a small script into /usr/bin/perl that hands off to an existing Perl of a Git for Windows SDK.
