completion: respect 'git -C <path>'
'git -C <path>' option(s) on the command line should be taken into
account during completion, because
- like '--git-dir=<path>', it can lead us to a different repository,
- a few git commands executed in the completion script do care about
in which directory they are executed, and
- the command for which we are providing completion might care about
in which directory it will be executed.
However, unlike '--git-dir=<path>', the '-C <path>' option can be
specified multiple times and their effect is cumulative, so we can't
just store a single '<path>' in a variable. Nor can we simply
concatenate a path from '-C <path1> -C <path2> ...', because e.g. (in
an arguably pathological corner case) a relative path might be
followed by an absolute path.
Instead, store all '-C <path>' options word by word in the
$__git_C_args array in the main git completion function, and pass this
array, if present, to 'git rev-parse --absolute-git-dir' when
discovering the repository in __gitdir(), and let it take care of
multiple options, relative paths, absolute paths and everything.
Also pass all '-C <path> options via the $__git_C_args array to those
git executions which require a worktree and for which it matters from
which directory they are executed from. There are only three such
cases:
- 'git diff-index' and 'git ls-files' in __git_ls_files_helper()
used for git-aware filename completion, and
- the 'git ls-tree' used for completing the 'ref:path' notation.
The other git commands executed in the completion script don't need
these '-C <path>' options, because __gitdir() already took those
options into account. It would not hurt them, either, but let's not
induce unnecessary code churn.

rev-parse: add '--absolute-git-dir' option
The output of 'git rev-parse --git-dir' can be either a relative or an
absolute path, depending on whether the current working directory is
at the top of the worktree or the .git directory or not, or how the
path to the repository is specified via the '--git-dir=<path>' option
or the $GIT_DIR environment variable. And if that output is a
relative path, then it is relative to the directory where any 'git
-C <path>' options might have led us.
This doesn't matter at all for regular scripts, because the git
wrapper automatically takes care of changing directories according to
the '-C <path>' options, and the scripts can then simply follow any
path returned by 'git rev-parse --git-dir', even if it's a relative
path.
Our Bash completion script, however, is unique in that it must run
directly in the user's interactive shell environment. This means that
it's not executed through the git wrapper and would have to take care
of any '-C <path> options on its own, and it can't just change
directories as it pleases. Consequently, adding support for taking
any '-C <path>' options on the command line into account during
completion turned out to be considerably more difficult, error prone
and required more subshells and git processes when it had to cope with
a relative path to the .git directory.
Help this rather special use case and teach 'git rev-parse' a new
'--absolute-git-dir' option which always outputs a canonicalized
absolute path to the .git directory, regardless of whether the path is
discovered automatically or is specified via $GIT_DIR or 'git
--git-dir=<path>'.

completion: fix completion after 'git -C <path>'
The main completion function finds the name of the git command by
iterating through all the words on the command line in search for the
first non-option-looking word. As it is not aware of 'git -C's
mandatory path argument, if the '-C <path>' option is present, 'path'
will be the first such word and it will be mistaken for a git command.
This breaks completion in various ways:
- If 'path' happens to match one of the commands supported by the
completion script, then options of that command will be offered.
- If 'path' doesn't match a supported command and doesn't contain any
characters not allowed in Bash identifier names, then the
completion script does basically nothing and Bash in turn falls
back to filename completion for all subsequent words.
- Otherwise, if 'path' does contain such an unallowed character, then
it leads to a more or less ugly error message in the middle of the
command line. The standard '/' directory separator is such a
character, and it happens to trigger one of the uglier errors:
$ git -C some/path <TAB>sh.exe": declare: `_git_some/path': not a valid identifier
error: invalid key: alias.some/path
Fix this by skipping 'git -C's mandatory path argument while iterating
over the words on the command line. Extend the relevant test with
this case and, while at it, with cases that needed similar treatment
in the past ('--git-dir', '-c', '--work-tree' and '--namespace').
Additionally, silence the standard error of the 'declare' builtins
looking for the completion function associated with the git command
and of the 'git config' query for the aliased command. So if git ever
learns a new option with a mandatory argument in the future, then,
though the completion script will again misbehave, at least the
command line will not be utterly disrupted by those error messages.

completion: list short refs from a remote given as a URL
e832f5c09680 (completion: avoid ls-remote in certain scenarios,
2013-05-28) turned a 'git ls-remote <remote>' query into a 'git
for-each-ref refs/remotes/<remote>/' to improve responsiveness of
remote refs completion by avoiding potential network communication.
However, it inadvertently made impossible to complete short refs from
a remote given as a URL, e.g. 'git fetch git://server.com/repo.git
<TAB>', because there is, of course, no such thing as
'refs/remotes/git://server.com/repo.git'.
Since the previous commit we tell apart configured remotes, i.e. those
that can have a hierarchy under 'refs/remotes/', from others that
don't, including remotes given as URL, so we know when we can't use
the faster 'git for-each-ref'-based approach.
Resurrect the old, pre-e832f5c09680 'git ls-remote'-based code for the
latter case to support listing short refs from remotes given as a URL.
The code is slightly updated from the original to
- take into account the path to the repository given on the command
line (if any), and
- omit 'ORIG_HEAD' from the query, as 'git ls-remote' will never
list it anyway.
When the remote given to __git_refs() doesn't exist, then it will be
handled by this resurrected 'git ls-remote' query. This code path
doesn't list 'HEAD' unconditionally, which has the nice side effect of

color_parse_mem: allow empty color spec
Prior to c2f41bf52 (color.c: fix color_parse_mem() with

interpreted as a color "reset". This was an accidental
outcome, and that commit turned it into an error.
However, scripts may pass the empty string as a default
value to "git config --get-color" to disable color when the
value is not defined. The git-add--interactive script does
this. As a result, the script is unusable since c2f41bf52
unless you have color.diff.plain defined (if it is defined,
then we don't parse the empty default at all).
Our test scripts didn't notice the recent breakage because
they run without a terminal, and thus without color. They
never hit this code path at all. And nobody noticed the
original buggy "reset" behavior, because it was effectively
a noop.
Let's fix the code to have an empty color name produce an
empty sequence of color codes. The tests need a few fixups:
- we'll add a new test in t4026 to cover this case. But
note that we need to tweak the color() helper. While
we're there, let's factor out the literal ANSI ESC
character. Otherwise it makes the diff quite hard to
read.
- we'll add a basic sanity-check in t4026 that "git add
-p" works at all when color is enabled. That would have
caught this bug, as well as any others that are specific
to the color code paths.
- 73c727d69 (log --graph: customize the graph lines with
config log.graphColors, 2017-01-19) added a test to
t4202 that checks some "invalid" graph color config.
Since ",, blue" before yielded only "blue" as valid, and
now yields "empty, empty, blue", we don't match the
expected output.
One way to fix this would be to change the expectation
to the empty color strings. But that makes the test much
less interesting, since we show only two graph lines,
both of which would be colorless.
Since the empty-string case is now covered by t4026,
let's remove them entirely here. They're just in the way
of the primary thing the test is supposed to be

builtin/commit.c: switch to strbuf, instead of snprintf()
Switch to dynamic allocation with strbuf, so we can avoid dealing
with magic numbers in the code and reduce the cognitive burden from
the programmers. The original code is correct, but programmers no
longer have to count bytes needed for static allocation to know that.
As a side effect of this change, we also reduce the snprintf()
calls, that may silently truncate results if the programmer is not
careful.

update-ref: add test cases for bare repository
The default behavior of update-ref to create reflogs differs in
repositories with worktree and bare ones. The existing tests cover only
the behavior of repositories with worktree.
This commit adds tests that assert the correct behavior in bare
repositories for update-ref. Two cases are covered:
- If core.logAllRefUpdates is not set, no reflogs should be created
- If core.logAllRefUpdates is true, reflogs should be created

refs: add option core.logAllRefUpdates = always
When core.logallrefupdates is true, we only create a new reflog for refs
that are under certain well-known hierarchies. The reason is that we
know that some hierarchies (like refs/tags) are not meant to change, and
that unknown hierarchies might not want reflogs at all (e.g., a
hypothetical refs/foo might be meant to change often and drop old
history immediately).
However, sometimes it is useful to override this decision and simply log
for all refs, because the safety and audit trail is more important than
the performance implications of keeping the log around.
This patch introduces a new "always" mode for the core.logallrefupdates
option which will log updates to everything under refs/, regardless
where in the hierarchy it is (we still will not log things like
ORIG_HEAD and FETCH_HEAD, which are known to be transient).

attempt to remove a default ACL if there is one. Same idea as 8ed0a740dd42bd0724aebed6e3b07c4ea2a2d5e8. (I guess I'm the only one who

git-p4: fix git-p4.mapUser on Windows
When running git-p4 on Windows, with multiple git-p4.mapUser entries in
git config - no user mappings are applied to the generated repository.
Reproduction Steps:
1. Add multiple git-p4.mapUser entries to git config on a Windows
machine
2. Attempt to clone a p4 repository
None of the user mappings will be applied.
This issue is actually caused by gitConfigList, using split(os.linesep)
to convert the output of git config --get-all into a list. On Windows,
os.linesep is equal to '\r\n' - however git.exe returns configuration
with a line seperator of '\n'.
This leads to the list returned by gitConfigList containing only one
element - which contains the full output of git config --get-all in
string form, which causes problems for the code introduced to
getUserMapFromPerforceServer in 10d08a149d ("git-p4: map a P4 user to
Git author name and email address", 2016-03-01)
This issue should be caught by the test introduced in 10d08a1, however
would require running on Windows to reproduce.
Using splitlines solves this issue, by splitting config on all
typical delimiters ('\n', '\r\n' etc.)

help: improve is_executable() on Windows
On Windows, executables need to have the file extension `.exe`, or they
are not executables. Hence, to support scripts, Git for Windows also
looks for a she-bang line by opening the file in question, and executing
it via the specified script interpreter.
To figure out whether files in the `PATH` are executable, `git help` has
code that imitates this behavior. With one exception: it *always* opens
the files and looks for a she-bang line *or* an `MZ` tell-tale
(nevermind that files with the magic `MZ` but without file extension
`.exe` would still not be executable).
Opening this many files leads to performance problems that are even more
serious when a virus scanner is running. Therefore, let's change the
code to look for the file extension `.exe` early, and avoid opening the
file altogether if we already know that it is executable.
See the following measurements (in seconds) as an example, where we
execute a simple program that simply lists the directory contents and
calls open() on every listed file:
With virus scanner running (coldcache):
$ ./a.exe /libexec/git-core/
