The `verbose` and `expire` options of the `git worktree prune`
subcommand have wrong descriptions in that they pretend to relate to

nothing to do with objects but only with worktrees. Fix the description
accordingly.

reset: add an example of how to split a commit into two

It is often useful to break a commit into multiple parts that are more
logical separations. This can be tricky to learn how to do without the
brute-force method if re-writing code or commit messages from scratch.

Add a section to the git-reset documentation which shows an example
process for how to use git add -p and git commit -c HEAD@{1} to
interactively break a commit apart and re-use the original commit
message as a starting point when making the new commit message.

document behavior of empty color name

Commit 55cccf4bb (color_parse_mem: allow empty color spec,
2017-02-01) clearly defined the behavior of an empty color
config variable. Let's document that, and give a hint about
why it might be useful.

It's important not to say that it makes the item uncolored,
because it doesn't. It just sets no attributes, which means
that any previous attributes continue to take effect.

The commands git-branch and git-tag accept the '--create-reflog'
option, and create reflog even when core.logallrefupdates
configuration is explicitly set not to.

On the other hand, the negated form '--no-create-reflog' is accepted
as a valid option but has no effect (other than overriding an
earlier '--create-reflog' on the command line). This silent noop may
puzzle users. To communicate that this is a known limitation, add a

color_parse_mem: allow empty color specJeff King Wed, 1 Feb 2017 00:21:29 +0000 (01:21 +0100)

color_parse_mem: allow empty color spec

Prior to c2f41bf52 (color.c: fix color_parse_mem() with
value_len == 0, 2017-01-19), the empty string was
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
checking.

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 = alwaysCornelius Weig Fri, 27 Jan 2017 10:09:47 +0000 (11:09 +0100)

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).

The "init creates a new deep directory (umask vs. shared)" test expects

fails if a default ACL is inherited from the working tree for git. So
attempt to remove a default ACL if there is one. Same idea as

git-p4: fix git-p4.mapUser on WindowsGeorge Vanburgh Wed, 25 Jan 2017 09:17:29 +0000 (09:17 +0000)

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 WindowsHeiko Voigt Mon, 30 Jan 2017 12:40:58 +0000 (13:40 +0100)

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/

doc: clarify distinction between sign-off and pgp-signing

The documentation for submission discourages pgp-signing, but demands
a proper sign-off by contributors. However, when skimming the headings,
the wording of the section for sign-off could mistakenly be understood
as concerning pgp-signing. Thus, new contributors could oversee the
necessary sign-off.

This commit improves the wording such that the section about sign-off
cannot be misunderstood as pgp-signing. In addition, the paragraph about
pgp-signing is changed such that it avoids the impression that
pgp-signing could be relevant at later stages of the submission.

test-lib: on FreeBSD, look for unzip(1) in /usr/local/bin/

Eric Wong reported that while FreeBSD has a /usr/bin/unzip, it uses
different semantics from those that are needed by Git's tests: When
passing the -a option to Info-Zip, it heeds the text attribute of the
.zip file's central directory, while FreeBSD's unzip ignores that
attribute.

The common work-around is to install Info-Zip on FreeBSD, into
/usr/local/bin/.

t/Makefile: add a rule to re-run previously-failed tests

This patch automates the process of determining which tests failed
previously and re-running them.

While developing patch series, it is a good practice to run the test
suite from time to time, just to make sure that obvious bugs are caught
early. With complex patch series, it is common to run `make -j15 -k
test`, i.e. run the tests in parallel and *not* stop at the first
failing test but continue. This has the advantage of identifying
possibly multiple problems in one big test run.

It is particularly important to reduce the turn-around time thusly on
Windows, where the test suite spends 45 minutes on the computer on which
this patch was developed.

It is the most convenient way to determine which tests failed after
running the entire test suite, in parallel, to look for left-over "trash
directory.t*" subdirectories in the t/ subdirectory. However, those
directories might live outside t/ when overridden using the
--root=<directory> option, to which the Makefile has no access. The next
best method is to grep explicitly for failed tests in the test-results/
directory, which the Makefile *can* access.

Please note that the often-recommended `prove` tool requires Perl, and
that opens a whole new can of worms on Windows. As no native Windows Perl
comes with Subversion bindings, we have to use a Perl in Git for Windows
that uses the POSIX emulation layer named MSYS2 (which is a portable
version of Cygwin). When using this emulation layer under stress, e.g.
when running massively-parallel tests, unexplicable crashes occur quite
frequently, and instead of having a solution to the original problem, the
developer now has an additional, quite huge problem. For that reason, this
developer rejected `prove` as a solution and went with this patch instead.

use absolute_pathdup()

Apply the semantic patch for converting callers that duplicate the
result of absolute_path() to call absolute_pathdup() instead, which
avoids an extra string copy to a static buffer.

status: be prepared for not-yet-started interactive rebase

Some developers might want to call `git status` in a working
directory where they just started an interactive rebase, but the
edit script is still opened in the editor.

Let's show a meaningful message in such cases.
