a6d15bc335 Do not use date.c:tm_to_time_t() from compat/mingw.c
To implement gettimeofday(), a broken-down UTC time was requested from the
system using GetSystemTime(), then tm_to_time_t() was used to convert it
to a time_t because it does not look at the current timezone, which
mktime() would do.

Use GetSystemTimeAsFileTime() and a different conversion path to avoid this
back-reference from the compatibility layer to the generic code.

44626dc7d5 MSVC: Windows-native implementation for subset of Pthreads API
This patch implements native to Windows subset of pthreads API used by Git.
It allows to remove Pthreads for Win32 dependency for MSVC, msysgit and
Cygwin.

[J6t: If the MinGW build was built as part of the msysgit build
environment, then threading was already enabled because the
pthreads-win32 package is available in msysgit. With this patch, we can now
enable threaded code unconditionally.]

b6f714f89a MSVC: Fix an "incompatible pointer types" compiler warning
In particular, the following warning is issued while compiling
compat/msvc.c:

    ...mingw.c(223) : warning C4133: 'function' : incompatible \
types - from '_stati64 *' to '_stat64 *'

which relates to a call of _fstati64() in the mingw_fstat()
function definition.

This is caused by various layers of macro magic and attempts to
avoid macro redefinition compiler warnings. For example, the call
to _fstati64() mentioned above is actually a call to _fstat64(),
and expects a pointer to a struct _stat64 rather than the struct
_stati64 which is passed to mingw_fstat().

The definition of struct _stati64 given in compat/msvc.h had the
same "shape" as the definition of struct _stat64, so the call to
_fstat64() does not actually cause any runtime errors, but the
structure types are indeed incompatible.

In order to avoid the compiler warning, we add declarations for the
mingw_lstat() and mingw_fstat() functions and supporting macros to
msvc.h, suppressing the corresponding declarations in mingw.h, so
that we can use the appropriate structure type (and function) names
from the msvc headers.

75301f9015 Windows: avoid the "dup dance" when spawning a child process
When stdin, stdout, or stderr must be redirected for a child process that
on Windows is spawned using one of the spawn() functions of Microsoft's
C runtime, then there is no choice other than to

1. make a backup copy of fd 0,1,2 with dup
2. dup2 the redirection source fd into 0,1,2
3. spawn
4. dup2 the backup back into 0,1,2
5. close the backup copy and the redirection source

We used this idiom as well -- but we are not using the spawn() functions
anymore!

Instead, we have our own implementation. We had hardcoded that stdin,
stdout, and stderr of the child process were inherited from the parent's
fds 0, 1, and 2. But we can actually specify any fd.

With this patch, the fds to inherit are passed from start_command()'s
WIN32 section to our spawn implementation. This way, we can avoid the
backup copies of the fds.

The backup copies were a bug waiting to surface: The OS handles underlying
the dup()ed fds were inherited by the child process (but were not
associated with a file descriptor in the child). Consequently, the file or
pipe represented by the OS handle remained open even after the backup copy
was closed in the parent process until the child exited.

Since our implementation of pipe() creates non-inheritable OS handles, we
still dup() file descriptors in start_command() because dup() happens to
create inheritable duplicates. (A nice side effect is that the fd cleanup
in start_command is the same for Windows and Unix and remains unchanged.)

3e34d66577 Windows: simplify the pipe(2) implementation
Our implementation of pipe() must create non-inheritable handles for the
reason that when a child process is started, there is no opportunity to
close the unneeded pipe ends in the child (on POSIX this is done between
fork() and exec()).

Previously, we used the _pipe() function provided by Microsoft's C runtime
(which creates inheritable handles) and then turned the handles into
non-inheritable handles using the DuplicateHandle() API.

Simplify the procedure by using the CreatePipe() API, which can create
non-inheritable handles right from the beginning.

928500e00e Windows: boost startup by avoiding a static dependency on shell32.dll
This DLL is only needed to invoke the browser in a "git help" call. By
looking up the only function that we need at runtime, we can avoid the
startup costs of this DLL.

DLL usage can be profiled with Microsoft's Dependency Walker. For example,
a call to "git diff-files" loaded

before:  19 DLLs
after:    9 DLLs

As a result, the runtime of 'make -j2 test' went down from 16:00min

ee6fc514f2 Show submodules as modified when they contain a dirty work tree
Until now a submodule only then showed up as modified in the supermodule
when the last commit in the submodule differed from the one in the index
or the diffed against commit of the superproject. A dirty work tree
containing new untracked or modified files in a submodule was
undetectable when looking at it from the superproject.

Now git status and git diff (against the work tree) in the superproject
will also display submodules as modified when they contain untracked or
modified files, even if the compared ref matches the HEAD of the
submodule.

e8189ee90e Test t5560: Fix test when run with dash
A command invocation preceded by variable assignments, i.e.

	VAR1=VAL1 VAR2=VAL2 ... command args

are implemented by dash and ksh in such a way not to export these
variables, and keep the values after the command finishes, when the
command is a shell function.  POSIX.1 "2.9.5 Function Definition Command"
specifies this behaviour.

Many shells however treat this construct the same way as they are calling
external commands.  They export the variables during the duration of
command, and resets their values after command returns.

The test relied on the behaviour of the latter kind.

There are a few cases of user identity information that we consider
interesting:

  (1) When the author and committer identities do not match.

In these cases, we already show the information in the commit

because they might use "-m" or "-F". With this patch, we show these
interesting cases after the commit, along with the subject and
change summary. The new output looks like:

0a0416a34a strbuf_expand: convert "%%" to "%"
The only way to safely quote arbitrary text in a pretty-print user
format is to replace instances of "%" with "%x25". This is slightly
unreadable, and many users would expect "%%" to produce a single
"%", as that is what printf format specifiers do.

This patch converts "%%" to "%" for all users of strbuf_expand():

 (1) git-daemon interpolated paths

 (2) pretty-print user formats

 (3) merge driver command lines

Case (1) was already doing the conversion itself outside of
strbuf_expand(). Case (2) is the intended beneficiary of this patch.
Case (3) users probably won't notice, but as this is user-facing
behavior, consistently providing the quoting mechanism makes sense.

ee0a4afbe2 rebase -i: Extract a function "commit_message"
...instead of repeating the same short but slightly obscure blob of
code in several places.

f99e269c44 rebase -i: Simplify commit counting for generated commit messages
Read the old count from the first line of the old commit message
rather than counting the number of commit message blocks in the file.
This is simpler, faster, and more robust (e.g., it cannot be confused
by strange commit message contents).

5065ed296a rebase -i: Improve consistency of commit count in generated commit messages
Use the numeral "2" instead of the word "two" when two commits are
being interactively squashed.  This makes the treatment consistent
with that for higher numbers of commits.

959c0d06ea t3404: Test the commit count in commit messages generated by "rebase -i"
The first line of commit messages generated for "rebase -i"
squash/fixup commits includes a count of the number of commits that
are being combined.  Add machinery to check that this count is
correct, and add such a check to some test cases.
