On Windows, there are dramatic problems when a command line grows
beyond PATH_MAX, which is restricted to 8191 characters on XP and
later (according to http://support.microsoft.com/kb/830473).
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.

Commit a31e626 (completion: optimize refs completion) introduced a
regression for ZSH users: ref names were completed with a quoted trailing
space (i.e. "git checkout ma" completes to "git checkout master\ "). The
space is convenient for bash users since we use "-o nospace", but a
quoted space is worse than nothing. The absence of trailing space for ZSH
is a long-standing issue, that this patch is not fixing. We just fix the
regression by not appending a space when the shell is ZSH.

At least for cross-platform projects, it makes sense to hide the
files starting with a dot, as this is the behavior on Unix/MacOSX.
However, at least Eclipse has problems interpreting the hidden flag
correctly, so the default is to hide only the .git/ directory.
The config setting core.hideDotFiles therefore supports not only
'true' and 'false', but also 'dotGitOnly'.
[jes: clarified the commit message, made git init respect the setting
by marking the .git/ directory only after reading the config, and added
documentation, and rebased on top of current junio/next]

This has the effect of increasing the address space from 2GB to 4GB under
64-bit Windows, reducing the likelihood of an "out of memory" error when
e.g. repacking a large repository. The test suite passes with this
patch, with and without the MEM_TOP_DOWN flag added to all VirtualAlloc
calls. While this is no guarantee that there are no issues with large
memory support (it could break Git on other setups than mine, for
example), it at least increases the chance that nothing obvious goes wrong
(such as errors introduced by faulty sign extension, say, with ssize_t).

The dreaded "your vnsprintf is broken (returned -1)" error is back. At

On WinXP, the windows credential helper doesn't work at all (due to missing
Cred[Un]PackAuthenticationBuffer APIs). On Win7, the credential format used
by wincred is incompatible with native Windows tools (such as the control
panel applet or 'cmdkey.exe /generic'). These Windows tools only set the
TargetName, UserName and CredentialBlob members of the CREDENTIAL
structure (where CredentialBlob is the UTF-16-encoded password).
Remove the unnecessary packing / unpacking of the password, along with the
related API definitions, for compatibility with Windows XP.
Don't use CREDENTIAL_ATTRIBUTEs to identify credentials for compatibility
with Windows credential manager tools. Parse the protocol, username, host
and path fields from the credential's target name instead.
Credentials created with an old wincred version will have mangled or empty
passwords after this change.

The previous implementation said that the filesystem information on
Windows is not reliable to determine whether a file is executable.
To find gather this information it was peeking into the first two bytes
of a file to see whether it looks executable.
Apart from the fact that on Windows executables are usually defined as
such by their extension it lead to slow opening of help file in some
situations.
When you have virus scanner running calling open on an executable file
is a potentially expensive operation. See the following measurements (in
seconds) for example.
With virus scanner running (coldcache):
$ ./a.exe /libexec/git-core/

I played around with this quite a bit. After trying some more complex
schemes, I found that what worked best is to just sleep 1 millisecond
between iterations. Though it's a very short time, it still completely
eliminates the busy wait condition, without hurting perf.
There code uses SleepEx(1, TRUE) to sleep. See this page for a good
discussion of why that is better than calling SwitchToThread, which
is what was used previously:
http://stackoverflow.com/questions/1383943/switchtothread-vs-sleep1
Note that calling SleepEx(0, TRUE) does *not* solve the busy wait.
The most striking case was when testing on a UNC share with a large repo,
on a single CPU machine. Without the fix, it took 4 minutes 15 seconds,
and with the fix it took just 1:08! I think it's because git-upload-pack's
busy wait was eating the CPU away from the git process that's doing the
real work. With multi-proc, the timing is not much different, but tons of
CPU time is still wasted, which can be a killer on a server that needs to
do bunch of other things.
I also tested the very fast local case, and didn't see any measurable
difference. On a big repo with 4500 files, the upload-pack took about 2
seconds with and without the fix.
Apparently the signal handling is not quite correct in the fsckobject
handling (most likely we rely on a side effect that lets us still output
some message after receiving a signal 13 but in the BuildHive setup this
fails intermittently).
As a consequence, the push in t5504 does fail as expected, but fails to
output anything (unexpected). Since this is good enough for now, let's
handle an empty output as success, too.
