We already skip over loose refs under $GIT_DIR/refs if the name
ends with ".lock", so creating a branch named "foo.lock" will not
appear in the output of "git branch", "git for-each-ref", nor will
its commit be considered reachable by "git rev-list --all".
In the latter case this is especially evil, as it may cause
repository corruption when objects reachable only through such a
ref are deleted by "git prune".
It should be reasonably safe to deny use of ".lock" as a ref suffix.
In prior versions of Git such branches would be "phantom branches";
you can create it, but you can't see it in "git branch" output.

MinGW: Quote arguments for subprocesses that contain a single-quote
Before a process can be spawned by mingw_spawnve, arguments must be
surrounded by double-quotes if special characters are present. This is
necessary because the startup code of the spawned process will expand
arguments that look like glob patterns. "Normal" Windows command line
utilities expand only * and ?, but MSYS programs, including bash, are
different: They also expand braces, and this has already been taken care
of by compat/mingw.c:quote_arg().
But MSYS programs also treat single-quotes in a special way: Arguments
between single-quotes are spliced together (with spaces) into a word.
With this patch this treatment is avoided by quoting arguments that contain
single-quotes.
This lets t4252 pass on Windows.

avoid possible overflow in delta size filtering computation
On a 32-bit system, the maximum possible size for an object is less than
4GB, while 64-bit systems may cope with larger objects. Due to this
limitation, variables holding object sizes are using an unsigned long
type (32 bits on 32-bit systems, or 64 bits on 64-bit systems).
When large objects are encountered, and/or people play with large delta
depth values, it is possible for the maximum allowed delta size
computation to overflow, especially on a 32-bit system. When this
occurs, surviving result bits may represent a value much smaller than
what it is supposed to be, or even zero. This prevents some objects
from being deltified although they do get deltified when a smaller depth
limit is used. Fix this by always performing a 64-bit multiplication.

Some people and foreign SCM converter may have named their branches
as frotz@24 and we still want to keep supporting it.
However, "git branch frotz@{24}" is a disaster. It cannot even
checked out because "git checkout frotz@{24}" will interpret it as
"detach the HEAD at twenty-fourth reflog entry of the frotz branch".
(2) a refname that ends with a dot.
We already reject a path component that begins with a dot, primarily
to avoid ambiguous range interpretation. If we allowed ".B" as a
valid ref, it is unclear if "A...B" means "in dot-B but not in A" or
"either in A or B but not in both".
But for this to be complete, we need also to forbid "A." to avoid "in
B but not in A-dot". This was not a problem in the original range
notation, but we should have added this restriction when three-dot
notation was introduced.
Unlike "no dot at the beginning of any path component" rule, this
rule does not have to be "no dot at the end of any path component",
because you cannot abbreviate the tail end away, similar to you can
say "dot-B" to mean "refs/heads/dot-B".
For these reasons, it is not likely people created branches with these
names on purpose, but we have allowed such names to be used for quite some
time, and it is possible that people created such branches by mistake or
by accident.
To help people with branches with such unfortunate names to recover,
we still allow "branch -d 'bad.'" to delete such branches, and also allow
"branch -m bad. good" to rename them.

diff --cached: do not borrow from a work tree when a path is marked as assume-unchanged
When the index says that the file in the work tree that corresponds to the
blob object that is used for comparison is known to be unchanged, "diff"
reads from the file and applies convert_to_git(), instead of inflating the
object, to feed the internal diff engine with, because an earlier
benchnark found that it tends to be faster to use this optimization.
However, the index can lie when the path is marked as assume-unchanged.
Disable the optimization for such paths.

t5503: GIT_DEBUG_SEND_PACK is not supported on MinGW
The test opens fd 3 and instructs git-upload-pack (via GIT_DEBUG_SEND_PACK)
to log information to that channel.
The way in which new processes are spawned by git on MinGW does not inherit
all file descriptors to the child processes, but only 0, 1, and 2.
The tests in t5503 require that file descriptor 3 is inherited from
git-fetch to git-upload-pack.
A complete implementation is non-trivial and not warranted just to satisfy
this test. Note that the incompleteness applies only to the executables
that use compat/mingw.c; bash and perl (the other important executables
used by git) are complete, of course.
t7004: Use prerequisite tags to skip tests that need gpg
The tests are skipped if no gpg was found or if gpg is version 1.0.6.
Previously, the latter condition was checked a bit later in the test file
so that the tag verification tests would be exercised. These are now
skipped as well, but only because we would need a facility to revoke a
test prerequisite, which we do not have.
The test verifies that glob special characters can be escaped with
backslashes. In particular, the string fo\[ou\]bar is given to git.
On Windows, this does not work because backslashes are first of all
directory separators, and first thing git does with a pathspec from the
command line is to convert backslashes to forward slashes.
Since the MSYS bash mangles absolute paths that it passes as command line
arguments to non-MSYS progams (such as git or test-path-utils), we have to
bend over backwards to squeeze some usefulness out of the existing tests.
In particular, a set of path normalization tests is added that test
relative paths. Some paths in the ancestor path tests are adjusted to help
MSYS bash's path mangling heuristics.
Use prerequisite tags to skip tests that depend on symbolic links
Many tests depend on that symbolic links work. This introduces a check
that sets the prerequisite tag SYMLINKS if the file system supports
symbolic links. Since so many tests have to check for this prerequisite,
we do the check in test-lib.sh, so that we don't need to repeat the test
in many scripts.
To check for 'ln -s' failures, you can use a FAT partition on Linux:
- The filesystem supports names with tabs or new-lines.
- Files cannot be removed if their containing directory is read-only.
Previously, whether these preconditions are satisified was tested inside
test_expect_success. We move these tests outside because, strictly
speaking, they are not part of the tests.

pack-objects: don't loosen objects available in alternate or kept packs
If pack-objects is called with the --unpack-unreachable option then it
will unpack (i.e. loosen) all unreferenced objects from local not-kept
packs, including those that also exist in packs residing in an alternate
object database or a locally kept pack. The only user of this option is
git-repack.
In this case, repack will follow the call to pack-objects with a call to
prune-packed, which will delete these newly loosened objects, making the
act of loosening a waste of time. The unnecessary loosening can be
avoided by checking whether an object exists in a non-local pack or a
locally kept pack before loosening it.
This fixes the 'local packed unreachable obs that exist in alternate ODB
are not loosened' test in t7700.

Propagate --exec-path setting to external commands via GIT_EXEC_PATH
Let PATH0=$PATH that was set before the invocation.
Let /foo be a build directory.
Let /pfx be the installation prefix.
Let pfxexecpath=/pfx/libexec/git-core.
The following is going on when 'git --exec-path=/foo gc' is invoked:
1. git sets PATH=/foo:$PATH0 using the path from --exec-path
2. gc execs 'git repack' (note: no dash).
3. Since there is a git in /foo (it's a build directory), /foo/git is
taken.
4. No explicit exec-path is set this time, hence, this secondary git sets
PATH=$pfxexecpath:/foo:$PATH
5. Since 'repack' is not a built-in, execv_dashed_external execs
'git-repack' (note: dash).
6. There is a $pfxexecpath/git-repack, and it is taken.
7. This git-repack runs 'git pack-objects' (note: no dash).
8. There is no git in $pfxexecpath, but there is one in /foo. Hence,
/foo/git is run.
9. pack-objects is a builtin, hence, in effect /foo/git-pack-objects
is run.
As you can see, the way in which we previously set the PATH allowed to
mix gits of different vintage. By setting GIT_EXEC_PATH when --exec-path
was given on the command line, we reduce the confusion.

1) The new --kept-pack-only mechansim of rev-list/pack-objects has
replaced --unpacked=. This new mechansim does not operate solely on
"local" packs now. The result is that objects residing in an alternate
pack which has a .keep file will not be repacked with repack -a.
This flaw is only apparent when a commit object is the one residing in
an alternate kept pack.
2) The 'repack unpacked objects' and 'loosen unpacked objects' mechanisms
of pack-objects, i.e. --keep-unreachable and --unpack-unreachable,
now do not operate solely on local packs. The --keep-unreachable
option no longer has any callers, but --unpack-unreachable is used when
repack is called with '-A -d' and the local repo has existing packs.
In this case, objects residing in alternate, not-kept packs will be
loosened, and then immediately deleted by repack's call to
prune-packed.
The test must manually call pack-objects to avoid the call to
prune-packed that is made by repack when -d is used.

make oneline reflog dates more consistent with multiline format
The multiline reflog format (e.g., as shown by "git log -g")
will show HEAD@{<date>} rather than HEAD@{<count>} in two
situations:
1. If the user gave branch@{<date>} syntax to specify the
reflog
2. If the user gave a --date=<format> specifier
It uses the "normal" date format in case 1, and the
user-specified format in case 2.
The oneline reflog format (e.g., "git reflog show" or "git
log -g --oneline") will show the date in the same two
circumstances. However, it _always_ shows the date as a
relative date, and it always ignores the timezone.
In case 2, it seems ridiculous to trigger the date but use a
format totally different from what the user requested.
For case 1, it is arguable that the user might want to see
the relative date by default; however, the multiline version
shows the normal format.
This patch does three things:
- refactors the "relative_date" parameter to
show_reflog_message to be an actual date_mode enum,
since this is how it is used (it is passed to show_date)
- uses the passed date_mode parameter in the oneline
format (making it consistent with the multiline format)
- does not ignore the timezone parameter in oneline mode
