git-submodule.sh: shorten submodule SHA-1s using rev-parse
Until now, `git submodule summary` was always emitting 7-character
SHA-1s that have a higher chance of being ambiguous for larger
repositories. Use `git rev-parse --short` instead, which will
determine suitable short SHA-1 lengths.
When a submodule hasn't been initialized with "submodule init" or
not cloned, `git rev-parse` would not work in it yet; as a fallback,
use the original method of cutting at 7 hexdigits.

Users who want UTF-16 files in the working tree set the .gitattributes
like this:
test.txt working-tree-encoding=UTF-16
The unicode standard itself defines 3 allowed ways how to encode UTF-16.
The following 3 versions convert all back to 'g' 'i' 't' in UTF-8:
a) UTF-16, without BOM, big endian:
$ printf "\000g\000i\000t" | iconv -f UTF-16 -t UTF-8 | od -c 0000000 g i t
b) UTF-16, with BOM, little endian:
$ printf "\377\376g\000i\000t\000" | iconv -f UTF-16 -t UTF-8 | od -c 0000000 g i t
c) UTF-16, with BOM, big endian:
$ printf "\376\377\000g\000i\000t" | iconv -f UTF-16 -t UTF-8 | od -c 0000000 g i t
Git uses libiconv to convert from UTF-8 in the index into ITF-16 in the
working tree.
After a checkout, the resulting file has a BOM and is encoded in "UTF-16",
in the version (c) above.
This is what iconv generates, more details follow below.
iconv (and libiconv) can generate UTF-16, UTF-16LE or UTF-16BE:
d) UTF-16
$ printf 'git' | iconv -f UTF-8 -t UTF-16 | od -c 0000000 376 377 \0 g \0 i \0 t
e) UTF-16LE
$ printf 'git' | iconv -f UTF-8 -t UTF-16LE | od -c 0000000 g \0 i \0 t \0
f) UTF-16BE
$ printf 'git' | iconv -f UTF-8 -t UTF-16BE | od -c 0000000 \0 g \0 i \0 t
There is no way to generate version (b) from above in a Git working tree,
but that is what some applications need.
(All fully unicode aware applications should be able to read all 3 variants,
but in practise we are not there yet).
When producing UTF-16 as an output, iconv generates the big endian version
with a BOM. (big endian is probably chosen for historical reasons).
iconv can produce UTF-16 files with little endianess by using "UTF-16LE"
as encoding, and that file does not have a BOM.
Not all users (especially under Windows) are happy with this.
Some tools are not fully unicode aware and can only handle version (b).
Today there is no way to produce version (b) with iconv (or libiconv).
Looking into the history of iconv, it seems as if version (c) will
be used in all future iconv versions (for compatibility reasons).
Solve this dilemma and introduce a Git-specific "UTF-16LE-BOM".
libiconv can not handle the encoding, so Git pick it up, handles the BOM
and uses libiconv to convert the rest of the stream.
(UTF-16BE-BOM is added for consistency)

If the user gives an empty argument to --exec then git creates a todo
list that it cannot parse. The rebase starts to run before erroring out
with
error: missing arguments for exec
error: invalid line 2: exec
You can fix this with 'git rebase --edit-todo' and then run 'git rebase --continue'.
Or you can abort the rebase with 'git rebase --abort'.
Instead check for empty commands before starting the rebase.
Also check that the command does not contain any newlines as the
todo-list format is unable to cope with multiline commands. Note that
this changes the behavior, before this change one could do
git rebase --exec='echo one
exec echo two'
and it would insert two exec lines in the todo list, now it will error
out.

The fact that Git's test suite is implemented in Unix shell script that
is as portable as we can muster, combined with the fact that Unix shell
scripting is foreign to Windows (and therefore has to be emulated),
results in pretty abysmal speed of the test suite on that platform, for
pretty much no other reason than that language choice.
For comparison: while the Linux build & test is typically done within
about 8 minutes, the Windows build & test typically lasts about 80
minutes in Azure Pipelines.
To help with that, let's use the Azure Pipeline feature where you can
parallelize jobs, make jobs depend on each other, and pass artifacts
between them.
The tests are distributed using the following heuristic: listing all
test scripts ordered by size in descending order (as a cheap way to
estimate the overall run time), every Nth script is run (where N is the
total number of parallel jobs), starting at the index corresponding to
the parallel job. This slicing is performed by a new function that is
added to the `test-tool`.
To optimize the overall runtime of the entire Pipeline, we need to move
the Windows jobs to the beginning (otherwise there would be a very
decent chance for the Pipeline to be run only the Windows build, while
all the parallel Windows test jobs wait for this single one).
We use Azure Pipelines Artifacts for both the minimal Git for Windows
SDK as well as the built executables, as deduplication and caching close
to the agents makes that really fast. For comparison: while downloading
and unpacking the minimal Git for Windows SDK via PowerShell takes only
one minute (down from anywhere between 2.5 to 7 when using a shallow
clone), uploading it as Pipeline Artifact takes less than 30s and
downloading and unpacking less than 20s (sometimes even as little as
only twelve seconds).

t0061: workaround issues with --with-dashes and RUNTIME_PREFIX
When building Git with RUNTIME_PREFIX and starting a test helper from
t/helper/, it fails to detect a system prefix. The reason is that the
RUNTIME_PREFIX feature wants to use the location of the Git executable
to determine where the support files can be found, e.g. system-wide Git
config or the translations. This does not make any sense for the test
helpers, though, as they are distinctly not in a directory structure
resembling the final installation location of Git.
That is the reason why the test helpers rely on environment variables to
indicate the location of the needed support files, e.g.
GIT_TEXTDOMAINDIR. If this information is missing, the output will
contain warnings like this one:
RUNTIME_PREFIX requested, but prefix computation failed. [...]
In t0061, we did not expect that to happen, and it actually does not
happen in the regular case, because bin-wrappers/test-tool specifically
sets GIT_TEXTDOMAINDIR (and as a consequence, nothing in test-tool needs
to know anything about any runtime prefix).
However, with --with-dashes, bin-wrappers/test-tool is no longer called,
but t/helper/test-tool is called directly instead.
So let's just ignore the RUNTIME_PREFIX warning.

tests: include detailed trace logs with --write-junit-xml upon failure
The JUnit XML format lends itself to be presented in a powerful UI,
where you can drill down to the information you are interested in very
quickly.
For test failures, this usually means that you want to see the detailed
trace of the failing tests.
With Travis CI, we passed the `--verbose-log` option to get those
traces. However, that seems excessive, as we do not need/use the logs in
almost all of those cases: only when a test fails do we have a way to
include the trace.
So let's do something different when using Azure DevOps: let's run all
the tests with `--quiet` first, and only if a failure is encountered,
try to trace the commands as they are executed.
Of course, we cannot turn on `--verbose-log` after the fact. So let's
just re-run the test with all the same options, adding `--verbose-log`.
And then munging the output file into the JUnit XML on the fly.
Note: there is an off chance that re-running the test in verbose mode
"fixes" the failures (and this does happen from time to time!). That is
a possibility we should be able to live with. Ideally, we would label
this as "Passed upon rerun", and Azure Pipelines even know about that
outcome, but it is not available when using the JUnit XML format for
now:

mingw: be more generous when wrapping up the setitimer() emulation
Every once in a while, the Azure Pipeline fails with some semi-random
error: timer thread did not terminate timely
This error message means that the thread that is used to emulate the
setitimer() function did not terminate within 1,000 milliseconds.
The most likely explanation (and therefore the one we should assume to
be true, according to Occam's Razor) is that the timeout of one second
is simply not enough because we try to run so many tasks in parallel.

Instead of a shallow fetch followed by a sparse checkout, we are
better off by using a separate, dedicated Pipeline that bundles
the SDK as a build artifact, and then consuming that build artifact
here.
In fact, since this artifact will be used a lot, we spent substantial
time on figuring out a minimal subset of the Git for Windows SDK, just
enough to build and test Git. The result is a size reduction from around
1GB (compressed) to around 55MB (compressed). This also comes with the
change where we now call `usr\bin\bash.exe` directly, as `git-cmd.exe`
is not included in the minimal SDK.
That reduces the time to initialize Git for Windows' SDK from anywhere
between 2m30s-7m to a little over 1m.
Note: in theory, we could also use the DownloadBuildArtifacts@0 task
here. However, restricted permissions that are in effect when building
from forks would let this fail for PR builds, defeating the whole
purpose of the Azure Pipelines support for git.git.

ci: add a Windows job to the Azure Pipelines definition
Previously, we did not have robust support for Windows in our CI
definition, simply because Travis cannot accommodate our needs (even
after Travis added experimental Windows support very recently, it takes
longer than Travis' 50 minute timeout to build Git and run the test
suite on Windows). Instead, we used a hack that started a dedicated
Azure Pipeline from Travis and waited for the output, often timing out
(which is quite fragile, as we found out).
With this commit, we finally have first-class support for Windows in our
CI definition (in the Azure Pipelines one, that is).
Due to our reliance on Unix shell scripting in the test suite, combined
with the challenges on executing such scripts on Windows, the Windows
job currently takes a whopping ~1h20m to complete. Which is *far* longer
than the next-longest job takes (linux-gcc, ~35m).
Now, Azure Pipelines's free tier for open source projects (such as Git)
offers up to 10 concurrent jobs for free, meaning that the overall run
time will be dominated by the slowest job(s).
Therefore, it makes sense to start the Windows job first, to minimize
the time the entire build takes from start to end (which is now pretty
safely the run time of the Windows job).

possible, to make it easy to compare the Azure Pipeline builds to the
Travis ones (spoiler: some parts, especially the macOS jobs, are way
faster in Azure Pileines). Meaning: the number and the order of the jobs
added in this commit faithfully replicates what we have in .travis.yml.
Note: Our .travis.yml configuration has a Windows part that is *not*
replicated in the Azure Pipelines definition. The reason is easy to see:
As Travis cannot support our Windws needs (even with the preliminary
Windows support that was recently added to Travis after waiting for
*years* for that feature, our test suite would simply hit Travis'
timeout every single time).
To make things a bit easier to understand, we refrain from using the
`matrix` feature here because (while it is powerful) it can be a bit
confusing to users who are not familiar with CI setups. Therefore, we
use a separate phase even for similar configurations (such as GCC vs
Clang on Linux, GCC vs Clang on macOS).
Also, we make use of the shiny new feature we just introduced where the
test suite can output JUnit-style .xml files. This information is made
available in a nice UI that allows the viewer to filter by phase and/or
test number, and to see trends such as: number of (failing) tests, time
spent running the test suite, etc. (While this seemingly contradicts the
intention to replicate the Travis configuration as faithfully as
possible, it is just too nice to show off that capability here already.)

This patch introduces a conditional arm that defines some environment
variables and a function that displays the URL given the job id (to
identify previous runs for known-good trees).
Because Azure Pipeline's macOS agents already have git-lfs and gettext
installed, we can leave `BREW_INSTALL_PACKAGES` empty (unlike in
Travis' case).
Note: this patch does not introduce an Azure Pipelines definition yet;
That is left for the next patch.

tests: optionally write results as JUnit-style .xml
This will come in handy when publishing the results of Git's test suite
during an automated Azure DevOps run.
Note: we need to make extra sure that invalid UTF-8 encoding is turned
into valid UTF-8 (using the Replacement Character, \uFFFD) because
t9902's trace contains such invalid byte sequences, and the task in the
Azure Pipeline that uploads the test results would refuse to do anything
if it was asked to parse an .xml file with invalid UTF-8 in it.

The word "property" is vague here. Let's spell out that we mean the path
must be marked with the text attribute.
While we're here, let's make the paragraph a little easier to read by
de-emphasizing the "when core.autocrlf is false" bit. Putting it in the
first sentence obscures the main content, and many readers won't care
about autocrlf (i.e., anyone who is just following the gitattributes(7)
advice, which mainly discusses "text" and "core.eol").

We only override core.eol with core.autocrlf when the latter is set to
something besides "false". Let's make this more clear, and point the
reader to the git-config definitions, which discuss this in more detail.

test-lint: only use only sed [-n] [-e command] [-f command_file]
From `man sed` (on a Mac OS X box):
The -E, -a and -i options are non-standard FreeBSD extensions and may not be available
on other operating systems.
From `man sed` on a Linux box:
REGULAR EXPRESSIONS
POSIX.2 BREs should be supported, but they aren't completely because of
performance problems. The \n sequence in a regular expression matches the newline
character, and similarly for \a, \t, and other sequences.
The -E option switches to using extended regular expressions instead; the -E option
has been supported for years by GNU sed, and is now included in POSIX.
Well, there are still a lot of systems out there, which don't support it.
Beside that, IEEE Std 1003.1TM-2017, see
http://pubs.opengroup.org/onlinepubs/9699919799/
does not mention -E either.
To be on the safe side, don't allow -E (or -r, which is GNU).
Change check-non-portable-shell.pl to only accept the portable options:
sed [-n] [-e command] [-f command_file]

pack-objects: merge read_lock and lock in packing_data struct
Rename the packing_data lock to obd_lock and upgrade it to a recursive
mutex to make it suitable for current read_lock usages. Additionally
remove the superfluous #ifndef NO_PTHREADS guard around mutex
initialization in prepare_packing_data as the mutex functions
themselves are already protected.

pack-objects: move read mutex to packing_data struct
ac77d0c37 ("pack-objects: shrink size field in struct object_entry",
2018-04-14) added an extra usage of read_lock/read_unlock in the newly
introduced oe_get_size_slow for thread safety in parallel calls to
try_delta(). Unfortunately oe_get_size_slow is also used in serial
code, some of which is called before the first invocation of
ll_find_deltas. As such the read mutex is not guaranteed to be
initialized.
Resolve this by moving the read mutex to packing_data and initializing
it in prepare_packing_data which is initialized in cmd_pack_objects.

git-instaweb: add Python builtin http.server support
With this patch it is possible to launch git-instaweb by using
Python http.server CGI handler via `-d python` option.
git-instaweb generates a small wrapper around the http.server
(in GIT_DIR/gitweb/) that address a limitation of the CGI handler
where CGI scripts have to be in a cgi-bin subdirectory and
directory index can't be easily changed. To keep the implementation
small, gitweb is running on url `/cgi-bin/gitweb.cgi` and an automatic
redirection is done when opening `/`.
The generated wrapper is compatible with both Python 2 and 3.
Python is by default installed on most modern Linux distributions
which enables running `git instaweb -d python` without needing
anything else.
