d5651a48f5 Work around the command line limit on Windows
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.

c5198f87f2 Add a few more values for receive.denyCurrentBranch
For a long time, this developer thought that Git's insistence that
pushing into the current branch is evil was completely merited.

Just for fun, the original patch tried to show people that Git is right
there, and that it causes more trouble than it does good when Git allows
you to try to update the working tree for fast-forwards, or to detach the
HEAD, depending on some config settings.

Surprisingly, the opposite was shown.

So here is the support for two new options you can give the config
variable receive.denyCurrentBranch:

'updateInstead':
	Try to merge the working tree with the new tip of the branch
	(which can lead to really horrible merge conflicts).

'detachInstead':
	Detach the HEAD, thereby avoiding a disagreement between the
	HEAD and the index (as well as the working tree), possibly
	leaving the local user wondering how on earth her HEAD became
	so detached.

f9d69648b8 core.hidedotfiles: hide '.git' dir by default
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]

8b6a3a55b7 Win32: fix broken pipe detection
As of "Win32: Thread-safe windows console output", git-log no longer
terminates when the pager process dies. This is due to disabling buffering
for the replaced stdout / stderr streams. Git-log will periodically fflush
stdout (see write_or_die.c/mayble_flush_or_die()), but with no buffering,
this is a NOP that always succeeds (so we never detect the EPIPE error).

Exchange the original console handles with our console thread pipe handles
by accessing the internal MSVCRT data structures directly (which are
exposed via __pioinfo for some reason).

Implement this with minimal assumptions about the actual data structure to
make it work with different (hopefully even future) MSVCRT versions.

While messing with internal data structures is ugly, this patch solves the
problem at the source instead of adding more workarounds. We no longer need
the special winansi_isatty override, and the limitations documented in
"Win32: Thread-safe windows console output" are gone (i.e. fdopen(1/2)
returns unbuffered streams now, and isatty() for duped console file
descriptors works as expected).

33a45f8a89 Win32: fix detection of empty directories in is_dir_empty
On Windows XP (not Win7), directories cannot be deleted while a find handle
is open, causing "Deletion of directory '...' failed. Should I try again?"
prompts.

Prior to 19d1e75d "Win32: Unicode file name support (except dirent)",
these failures were silently ignored due to strbuf_free in is_dir_empty
resetting GetLastError to ERROR_SUCCESS.

Close the find handle in is_dir_empty so that git doesn't block deletion
of the directory even after all other applications have released it.

cde73ee852 Win32: keep the environment sorted
The Windows environment is sorted, keep it that way for O(log n)
environment access.

Change compareenv to compare only the keys, so that it can be used to
find an entry irrespective of the value.

Change lookupenv to binary seach for an entry. Return one's complement of
the insert position if not found (libc's bsearch returns NULL).

Replace MSVCRT's getenv with a minimal do_getenv based on the binary search
function.

Change do_putenv to insert new entries at the correct position. Simplify
the function by swapping if conditions and using memmove instead of for
loops.

Move qsort from make_environment_block to mingw_startup. We still need to
sort on startup to make sure that the environment is sorted according to
our compareenv function (while Win32 / CreateProcess requires the
environment block to be sorted case-insensitively, CreateProcess currently
doesn't enforce this, and some applications such as bash just don't care).

Note that environment functions are _not_ thread-safe and are not required
to be so by POSIX, the application is responsible for synchronizing access
to the environment. MSVCRT's getenv and our new getenv implementation are
better than that in that they are thread-safe with respect to other getenv
calls as long as the environment is not modified. Git's indiscriminate use
of getenv in background threads currently requires this property.

abe2460f6f Win32: use low-level memory allocation during initialization
As of d41489a6 "Add more large blob test cases", git's high-level memory
allocation functions (xmalloc, xmemdupz etc.) access the environment to
simulate limited memory in tests (see 'getenv("GIT_ALLOC_LIMIT")' in
memory_limit_check()). These functions should not be used before the
environment is fully initialized (particularly not to initialize the
environment itself).

The current solution ('environ = NULL; ALLOC_GROW(environ...)') only works
because MSVCRT's getenv() reinitializes environ when it is NULL (i.e. it
leaves us with two sets of unusabe (non-UTF-8) and unfreeable (CRT-
allocated) environments).

Add our own set of malloc-or-die functions to be used in startup code.

Also check the result of __wgetmainargs, which may fail if there's not
enough memory for wide-char arguments and environment.

This patch is in preparation of the sorted environment feature, which
completely replaces MSVCRT's getenv() implementation.

86cc334913 Win32: don't copy the environment twice when spawning child processes
When spawning child processes via start_command(), the environment and all
environment entries are copied twice. First by make_augmented_environ /
copy_environ to merge with child_process.env. Then a second time by
make_environment_block to create a sorted environment block string as
required by CreateProcess.

Move the merge logic to make_environment_block so that we only need to copy
the environment once. This changes semantics of the env parameter: it now
expects a delta (such as child_process.env) rather than a full environment.
This is not a problem as the parameter is only used by start_command()
(all other callers previously passed char **environ, and now pass NULL).

The merge logic no longer xstrdup()s the environment strings, so do_putenv
must not free them. Add a parameter to distinguish this from normal putenv.

Remove the now unused make_augmented_environ / free_environ API.

b4e54c8362 Win32: fix environment memory leaks
All functions that modify the environment have memory leaks.

Disable gitunsetenv in the Makefile and use env_setenv (via mingw_putenv)
instead (this frees removed environment entries).

Move xstrdup from env_setenv to make_augmented_environ, so that
mingw_putenv no longer copies the environment entries (according to POSIX
[1], "the string [...] shall become part of the environment"). This also
fixes the memory leak in gitsetenv, which expects a POSIX compliant putenv.

[1] http://pubs.opengroup.org/onlinepubs/009695399/functions/putenv.html

86de5015d6 Win32: Unicode environment (incoming)
Convert environment from UTF-16 to UTF-8 on startup.

No changes to getenv() are necessary, as the MSVCRT version is implemented
on top of char **environ.

However, putenv / _wputenv from MSVCRT no longer work, for two reasons:
1. they try to keep environ, _wenviron and the Win32 process environment
in sync, using the default system encoding instead of UTF-8 to convert
between charsets
2. msysgit and MSVCRT use different allocators, memory allocated in git
cannot be freed by the CRT and vice versa

Implement mingw_putenv using the env_setenv helper function from the
environment merge code.

Note that in case of memory allocation failure, putenv now dies with error
message (due to xrealloc) instead of failing with ENOMEM. As git assumes
setenv / putenv to always succeed, this prevents it from continuing with
incorrect settings.
