With this topic branch, the PERL5LIB variable is unset to avoid external
settings from interfering with Git's own Perl interpreter.
This branch also cleans up some of our Windows-only config setting code
(and this will need to be rearranged in the next merging rebase so that
the cleanup comes first, and fscache and longPaths support build on
top).

Git for Windows ships with its own Perl interpreter, and insists on
using it, so it will most likely wreak havoc if PERL5LIB is set before
launching Git.
Let's just unset that environment variables when spawning processes.
To make this feature extensible (and overrideable), there is a new
config setting `core.unsetenvvars` that allows specifying a
comma-separated list of names to unset before spawning processes.

In the Git for Windows project, we have ample precendent for config
settings that apply to Windows, and to Windows only.
Let's formalize this concept by introducing a platform_core_config()
function that can be #define'd in a platform-specific manner.
This will allow us to contain platform-specific code better, as the
corresponding variables no longer need to be exported so that they can
be defined in environment.c and be set in config.c

This topic branch brings support for choosing cURL's SSL backend at
runtime via http.sslBackend, based on patches already submitted to the
cURL project and backported to cURL 7.54.1 as used in Git for Windows'
SDK.

The Pull Request at https://github.com/curl/curl/pull/1601 adds support
for choosing the SSL backend at runtime to cURL, and will hopefully be
merged before version 7.56.0 comes out.
Git for Windows will ship with those patches backported to 7.54.1 (and
come August 9th, 2017, 7.55.0 and later).
This patch adds the Git side of that feature: by setting http.sslBackend
to "openssl" or "schannel", Git for Windows can now choose the SSL
backend at runtime.
This comes in handy because Secure Channel ("schannel") is the native
Windows solution, accessing the Windows Credential Store, thereby
allowing for enterprise-wide management of certificates. For historical
reasons, Git for Windows needs to support OpenSSL still, as it has
previously been the only supported SSL backend in Git for Windows for
almost a decade.

We run an early part of "git gc" that deals with refs before
daemonising (and not under lock) even when running a background
auto-gc, which caused multiple gc processes attempting to run the
early part at the same time. This is now prevented by running the
early part also under the GC lock.

The progress meter did not give a useful output when we haven't had
0.5 seconds to measure the throughput during the interval. Instead
show the overall throughput rate at the end, which is a much more

On Cygwin, similar to Windows, "git push //server/share/repository"
ought to mean a repository on a network share that can be accessed
locally, but this did not work correctly due to stripping the double
slashes at the beginning.
This may need to be heavily tested before it gets unleashed to the
wild, as the change is at a fairly low-level code and would affect
not just the code to decide if the push destination is local. There
may be unexpected fallouts in the path normalization.
* tb/push-to-cygwin-unc-path:

Code cleanup.

It gets a bit silly to add the commands to the name of the test script,

This topic branch addresses a problem identified in
https://github.com/git-for-windows/git/issues/439: while
cloning/fetching/pushing from "POSIX-ified UNC paths" (i.e. UNC paths
whose backslashes have been converted to forward slashes) works for some
time now, true UNC paths (with backslashes left intact) were handled
incorrectly. Example:
git clone //myserver/folder/repo.git
works, but
git clone \\myserver\folder\repo.git
(in CMD; in Git Bash, the backslashes would need to be doubled) used to
fail. The reason was an unexpected difference in command-line handling
between Win32 executables and MSYS2 ones (such as the shell that is used
by git-clone.exe to spawn git-upload-pack.exe).
This topic branch features a workaround *just* for the case where Git
passes stuff through sh.exe (which covers quite a few use cases,
though).
Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
The MSYS2 runtime does its best to emulate the command-line expansion
and de-quoting which would otherwise be performed by the calling shell.
However, in Git we pass arguments to subprocesses that we do *not* want
to be handled that way, 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. But sometimes we do call
MSYS2 executables, 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" 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.

Due to a quirk in Git's method to spawn git-upload-pack, there is a
problem when passing paths with backslashes in them: Git will force the
command-line through the shell, which has different quoting semantics in
Git for Windows (being an MSYS2 program) than regular Win32 executables
such as git.exe itself.
The symptom is that the first of the two backslashes in UNC paths of the
form \\myserver\folder\repository.git is *stripped off*.
Document this bug by introducing a test case.
Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
The use of a trailing backslash in an argument to the `tr` command is not
portable. While this test case is very specific to Windows, anyway, we
still should avoid that warning.
