getenv() on Windows looks up environment variables in a case-insensitive
manner. Even though all documentations claim that the environment is
case-insensitive, it is possible for applications to pass an environment
to child processes that has variables that differ only in case. Bash on
Windows does this, for example, and sh-i18n--envsubst depends on this
behavior.
With this patch environment variables are first looked up in a
case-sensitive manner; only if this finds nothing, the system's getenv() is
used as a fallback.

We want to use static lookup_env() in a subsequent change.
At first sight, this change looks innocent. But it is not due to the
#undef getenv. There is one caller of getenv between the old location and
the new location whose behavior could change. But as can be seen from the
defintion of mingw_getenv, the behavior for this caller does not change
substantially.
To ensure consistent behavior in the future, change all getenv callers
in mingw.c to use mingw_getenv.
With this patch, this is not a big deal, yet, but with the subsequent
change, where we teach getenv to do a case-sensitive lookup, the behavior
of all call sites is changed.

Somebody tried to compile fnmatch.c compatibility file on Interix and got
an error because no header included in the file on that platform defined
NULL. It usually comes from stddef.h and indirectly from other headers
like string.h, unistd.h, stdio.h, stdlib.h, etc., but with the way we
compile this file from our Makefile, inclusion of the header files that
are expected to define NULL in fnmatch.c do not happen because they are
protected with "#ifdef STDC_HEADERS", etc. which we do not pass.
As the least-impact workaround, give a fall-back definition when none of
the headers define NULL.

On Windows in case a program is accessing a file unlink or
move operations may fail. To give the user a chance to correct
this we simply wait until the user asks us to retry or fail.
This is useful because of the following use case which seem
to happen rarely but when it does it is a mess:
After making some changes the user realizes that he was on the
incorrect branch. When trying to change the branch some file
is still in use by some other process and git stops in the
middle of changing branches. Now the user has lots of files
with changes mixed with his own. This is especially confusing
on repositories that contain lots of files.
Although the recent implementation of automatic retry makes
this scenario much more unlikely lets provide a fallback as
a last resort.
Thanks to Albert Dvornik for disabling the question if users can't see it.
If the stdout of the command is connected to a terminal but the stderr
has been redirected, the odds are good that the user can't see any
question we print out to stderr. This will result in a "mysterious
hang" while the app is waiting for user input.
It seems better to be conservative, and avoid asking for input
whenever the stderr is not a terminal, just like we do for stdin.

Change the code to use the real PID, and use OpenProcess to get a

Since commit 0fcabdeb52, compat/bswap.h
redefined htonl and ntohl to bswap32 not only if bswap32 has been
defined earlier in compat/bswap.h (which is done only on selected
platforms), but also if bswap32 has been defined anywhere else. This
broke Git at least for NetBSD systems running on big-endian machines
(where ntohl and htonl should, of course, be NOOPs), since NetBSD
defines a bswap32 macro in the system headers.
So, we now undefine any previously defined bswap32 in compat/bswap.h
before defining our own.

Starting with 5256b00 (Use git_mkstemp_mode instead of plain mkstemp to

This is not allowed on Windows and results in many warnings of the form

Having recently added support for building git-imap-send on
Windows, we now link against OpenSSL libraries, and the linker
issues the following warning:
warning LNK4044: unrecognized option '/lssl'; ignored
In order to suppress the warning, we change the msvc linker
script to translate an '-lssl' parameter to the ssleay32.lib
library.
Note that the linker script was already including ssleay32.lib
(along with libeay32.lib) as part of the translation of the
'-lcrypto' library parameter. However, libeay32.dll does not
depend on ssleay32.dll and can be used stand-alone, so we remove
ssleay32.lib from the '-lcrypto' translation.
The dependence of ssleay32.dll on libeay32.dll is represented in
the Makefile by the NEEDS_CRYPTO_WITH_SSL build variable.
Also, add the corresponding change to the buildsystem generator.

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.

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.]

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.

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.)

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.
