The fall-back rules used when compilers don't support the -MMD switch
to generate makefile rules based on #includes have been out of date
since v1.7.12.1~22^2~8 (move git_version_string into version.c,
2012-06-02).
Checked with 'make CHECK_HEADER_DEPENDENCIES=yes'.

MSys works very hard to convert Unix-style paths into DOS-style ones.
*Very* hard.
So hard, indeed, that
git blame -L/hello/,/green/
is translated into something like
git blame -LC:/msysgit/hello/,C:/msysgit/green/
As seen in msys_p2w in src\msys\msys\rt\src\winsup\cygwin\path.cc, line
3204ff:
case '-':
//
// here we check for POSIX paths as attributes to a POSIX switch.
//
...
seemingly absolute POSIX paths in single-letter options get expanded by
msys.dll unless they contain '=' or ';'.
So a quick and very dirty fix is to use '-L/;*evil/'. (Using an equal sign
works only when it is before a comma, so in the above example, /=*green/
would still be converted to a DOS-style path.)
The -L mangling can be done by the script, just before the parameter is
passed to the executable. This version does not modify the body of the
tests and is active on MinGW only.

The path in a .git platform independent link file needs to be absolute
and under mingw we need it to be a windows type path, not a unix style
path so it should start with a drive letter and not a /.

On Windows, all native APIs are Unicode-based. It is impossible to pass
legacy encoded byte arrays to a process via command line or environment
variables. Disable the tests that try to do so.
In t3901, most tests still work if we don't mess up the repository encoding
in setup, so don't switch to ISO-8859-1 on MinGW.
Note that i18n tests that do their encoding tricks via encoded files (such
as t3900) are not affected by this.

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.

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.

ALLOC_GROW in mingw_putenv to reduce reallocations. Allocate a
sufficiently sized environment array in make_environment_block to prevent
reallocations.

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.

The environment on Windows is case-insensitive. Some environment functions
(such as unsetenv and make_augmented_environ) have always used case-
sensitive comparisons instead, while others (getenv, putenv, sorting in
spawn*) were case-insensitive.
Prevent potential inconsistencies by using case-insensitive comparison in
lookup_env (used by putenv, unsetenv and make_augmented_environ).

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
Note: This patch depends on taking control of char **environ and having
our own mingw_putenv (both introduced in "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.

This reverts commit df599e9612788b728ce43a03159b85f1fe624d6a.
As of 5e9637c6 "i18n: add infrastructure for translating Git with gettext",
eval_gettext uses MinGW envsubst.exe instead of git-sh-i18n--envsubst.exe
for variable substitution. This breaks git-submodule.sh messages and tests,
as envsubst.exe doesn't support case-sensitive environment lookup (the same
is true for almost everything on Windows, including MSys and Cygwin tools).

the conflicting variable in git-submodule.sh, so that it works on Windows
(i.e. with case-insensitive environment, regardless of the toolset).
Revert to the documented behaviour of case-insensitive environment on
Windows.

git commit -m with some iso8859-1 encoded stuff is doomed to fail in MinGW,
because Windows don't let you pass encoded bytes to a process (CreateProcessW
always takes a UTF-16LE encoded string).
It is safe to pass the iso8859-1 message using a file or a pipe.

Once upon a time, git-log was just "rev-list | diff-tree",
and we did not bother to test it separately. These days git-log
is implemented internally, but we want to make sure that the
rev-list to diff-tree pipeline continues to function. Let's
add a basic sanity test.

We generally want to avoid lookup_unknown_object, because it
results in allocating more memory for the object than may be
strictly necessary.
In this case, it is used to check whether we have an
already-parsed object before calling parse_object, to save
us from reading the object from disk. Using lookup_object
would be fine for that purpose, but we can take it a step
further. Since this code was written, parse_object already
learned the "check lookup_object" optimization, so we can
simply call parse_object directly.

The point of the "index" field of struct commit is that
every allocated commit would have one. It is supposed to be
an invariant that whenever object->type is set to
OBJ_COMMIT, we have a unique index.
Commit 969eba6 (commit: push commit_index update into
alloc_commit_node, 2014-06-10) covered this case for
newly-allocated commits. However, we may also allocate an
"unknown" object via lookup_unknown_object, and only later
convert it to a commit. We must make sure that we set the
commit index when we switch the type field.

We keep a static counter to set the commit index on newly
allocated objects. However, since we also need to set the
index on any_objects which are converted to commits, let's
make the counter available as a public function.
While we're moving it, let's make sure the counter is
allocated as an unsigned integer to match the index field in
"struct commit".

When we call lookup_commit, lookup_tree, etc, the logic goes
something like:
1. Look for an existing object struct. If we don't have
one, allocate and return a new one.
2. Double check that any object we have is the expected
type (and complain and return NULL otherwise).
3. Convert an object with type OBJ_NONE (from a prior
call to lookup_unknown_object) to the expected type.
We can encapsulate steps 2 and 3 in a helper function which
checks whether we have the expected object type, converts
OBJ_NONE as appropriate, and returns the object.
Not only does this shorten the code, but it also provides
one central location for converting OBJ_NONE objects into
objects of other types. Future patches will use that to
enforce type-specific invariants.
Since this is a refactoring, we would want it to behave
exactly as the current code. It takes a little reasoning to
see that this is the case:
- for lookup_{commit,tree,etc} functions, we are just
pulling steps 2 and 3 into a function that does the same
thing.
- for the call in peel_object, we currently only do step 3
(but we want to consolidate it with the others, as
mentioned above). However, step 2 is a noop here, as the
surrounding conditional makes sure we have OBJ_NONE
(which we want to keep to avoid an extraneous call to
sha1_object_info).
- for the call in lookup_commit_reference_gently, we are
currently doing step 2 but not step 3. However, step 3
is a noop here. The object we got will have just come
from deref_tag, which must have figured out the type for
each object in order to know when to stop peeling.
Therefore the type will never be OBJ_NONE.
