When installing p4 as a dependency, we used to pipe output of "p4 -V"
and "p4d -V" to validate the installation and output a condensed version
information. But this would hide potential errors of p4 and would stop
with an empty output. E.g.: p4d version 16.2 running on ubuntu 22.04
causes sigfaults, even before it produces any output.
By removing the pipe after "p4 -V" and "p4d -V", we may get a
verbose output, and stop immediately on errors because we have "set
-e" in "ci/lib.sh". Since we won't look at these trace logs unless
something fails, just including the raw output seems most sensible.

Address the root cause of technical debt we've been carrying since
sha1collisiondetection was made the default in [1]. In a preceding
commit we narrowly fixed a bug where the "DC_SHA1" variable would be
unset (in combination with "NO_APPLE_COMMON_CRYPTO=" on OSX), even
though we had the sha1collisiondetection library enabled.
But the only reason we needed to have such a user-exposed knob went
away with [1], and it's been doing nothing useful since then. We don't
care if you define DC_SHA1=*, we only care that you don't ask for any
other SHA-1 implementation. If it turns out that you didn't, we'll use
sha1collisiondetection, whether you had "DC_SHA1" set or not.
As a result of this being confusing we had e.g. [2] for cmake and the
recent [3] for ci/lib.sh setting "DC_SHA1" explicitly, even though
this was always a NOOP.
A much simpler way to do this is to stop having the Makefile and
CMakeLists.txt set "DC_SHA1" to be picked up by the test-lib.sh, let's
instead add a trivial "test-tool sha1-is-sha1dc". It returns zero if
we're using sha1collisiondetection, non-zero otherwise.

7b8cfe34 (Merge branch 'ed/fsmonitor-on-networked-macos',
2022-10-17) broke the build on macOS with sha1dc by bypassing our
hash abstraction (git_SHA_CTX etc.), but it wasn't caught before the
problematic topic was merged down to the 'master' branch. Nobody
was even compile testing with DC_SHA1 set, although it is the
recommended choice in these days for folks when they use SHA-1.
This was because the default for macOS uses Apple Common Crypto, and
both of the two CI jobs did not override the default. Tweak one of
them to use DC_SHA1 to improve the coverage.
We may want to give similar diversity for Linux jobs so that some of
them build with other implementations of SHA-1; they currently all
build and test with DC_SHA1 as that is the default on everywhere
other than macOS.
But let's start small to fill only the immediate need.

In the previous commit, we ensured that grouping is used for the build

to transmogrify the output.
Note: If `set -o pipefail` was available, we could do this in a little
more elegant way. But since some of the steps are run using `dash`, we
have to do a little `{ ...; echo $? >exit.status; } | ...` dance.

In the preceding commit we moved away from using xgettext(1) to both
generate the po/git.pot, and to merge the incrementally generated
po/git.pot+ file as we sourced translations from C, shell and Perl.
Doing it this way, which dates back to my initial
implementation[1][2][3] was conflating two things: With xgettext(1)
the --from-code both controls what encoding is specified in the
po/git.pot's header, and what encoding we allow in source messages.
We don't ever want to allow non-ASCII in *source messages*, and doing
so has hid e.g. a buggy message introduced in
a6226fd772 (submodule--helper: convert the bulk of cmd_add() to C,
2021-08-10) from us, we'd warn about it before, but only when running
"make pot", but the operation would still succeed. Now we'll error out
on it when running "make pot".
Since the preceding Makefile changes made this easy: let's add a "make
check-pot" target with the same prerequisites as the "po/git.pot"
target, but without changing the file "po/git.pot". Running it as part
of the "static-analysis" CI target will ensure that we catch any such
issues in the future. E.g.:
$ make check-pot

When investigating a test failure, the time that matters most is the
time it takes from getting aware of the failure to displaying the output
of the failing test case.
You currently have to know a lot of implementation details when
investigating test failures in the CI runs. The first step is easy: the
failed job is marked quite clearly, but when opening it, the failed step
is expanded, which in our case is the one running
`ci/run-build-and-tests.sh`. This step, most notably, only offers a
high-level view of what went wrong: it prints the output of `prove`
which merely tells the reader which test script failed.
The actually interesting part is in the detailed log of said failed
test script. But that log is shown in the CI run's step that runs
`ci/print-test-failures.sh`. And that step is _not_ expanded in the web
UI by default. It is even marked as "successful", which makes it very
easy to miss that there is useful information hidden in there.
Let's help the reader by showing the failed tests' detailed logs in the
step that is expanded automatically, i.e. directly after the test suite
failed.
This also helps the situation where the _build_ failed and the
`print-test-failures` step was executed under the assumption that the
_test suite_ failed, and consequently failed to find any failed tests.
An alternative way to implement this patch would be to source
`ci/print-test-failures.sh` in the `handle_test_failures` function to
show these logs. However, over the course of the next few commits, we
want to introduce some grouping which would be harder to achieve that
way (for example, we do want a leaner, and colored, preamble for each
failed test script, and it would be trickier to accommodate the lack of
nested groupings in GitHub workflows' output).

In the web UI of GitHub workflows, failed runs are presented with the
job step that failed auto-expanded. In the current setup, this is not
helpful at all because that shows only the output of `prove`, which says
which test failed, but not in what way.
What would help understand the reader what went wrong is the verbose
test output of the failed test.
The logs of the failed runs do contain that verbose test output, but it
is shown in the _next_ step (which is marked as succeeding, and is
therefore _not_ auto-expanded). Anyone not intimately familiar with this
would completely miss the verbose test output, being left mostly
puzzled with the test failures.
We are about to show the failed test cases' output in the _same_ step,
so that the user has a much easier time to figure out what was going
wrong.
But first, we must partially revert the change that tried to improve the
CI runs by combining the `Makefile` targets to build into a single
`make` invocation. That might have sounded like a good idea at the time,
but it does make it rather impossible for the CI script to determine
whether the _build_ failed, or the _tests_. If the tests were run at
all, that is.
So let's go back to calling `make` for the build, and call `make test`
separately so that we can easily detect that _that_ invocation failed,
and react appropriately.

macOS CI jobs have been occasionally flaky due to tentative version

Since 522354d70f (Add Travis CI support, 2015-11-27) the CI has used

Let's use https instead for good measure. I don't think we need to
worry about the DNS or network between the GitHub CI and perforce.com
being MitM'd, but using https gives us extra validation of the payload
at least, and is one less thing to worry about when checking where
else we rely on non-TLS'd http connections.
Also, use the same download site at perforce.com for Linux and macOS

Perfoce's cask in brew is meant[1] to be used only by humans, so replace
its use from the CI with a scripted binary download which is less likely
to fail, as it is done in Linux.
Kept the logic together so it will be less likely to break when moved
around as on the fly code changes in this area are settled, at which
point it will also feasable to ammend it to avoid some of the hardcoded
values by using similar variables to the ones Linux does.
In that same line, a POSIX sh syntax is used instead of the similar one
used in Linux in preparation for an unrelated future change that might
change the shell currently configured for it.
This change reintroduces the risk that the installed binaries might not
work because of being quarantined that was fixed with 5ed9fc3fc8 (ci:

now was also punted for simplicity and since the affected cloud provider
is scheduled to be retired with an on the fly change, but should be
addressed if that other change is not integrated further.
The discussion on the need to keep 2 radically different versions of
the binaries to be tested with Linux vs macOS or how to upgrade to
newer versions now that brew won't do that automatically for us has
been punted for now as well. On that line the now obsolete comment
about it in lib.sh was originally being updated by this change but
created conflicts as it is moved around by other on the fly changes,
so will be addressed independently as well.

We have a copy of uncompress2() implementation in compat/ so that we
can build with an older version of zlib that lack the function, and
the build procedure selects if it is used via the NO_UNCOMPRESS2
$(MAKE) variable. This is yet another "annoying" knob the porters
need to tweak on platforms that are not common enough to have the
default set in the config.mak.uname file.
Attempt to instead ask the system header <zlib.h> to decide if we
need the compatibility implementation. This is a deviation from the
way we have been handling the "compatiblity" features so far, and if
it can be done cleanly enough, it could work as a model for features
that need compatibility definition we discover in the future. With
that goal in mind, avoid expedient but ugly hacks, like shoving the
code that is conditionally compiled into an unrelated .c file, which
may not work in future cases---instead, take an approach that uses a
file that is independently compiled and stands on its own.
Compile and link compat/zlib-uncompress2.c file unconditionally, but
conditionally hide the implementation behind #if/#endif when zlib
version is 1.2.9 or newer, and unconditionally archive the resulting
object file in the libgit.a to be picked up by the linker.
There are a few things to note in the shape of the code base after
this change:
- We no longer use NO_UNCOMPRESS2 knob; if the system header
<zlib.h> claims a version that is more cent than the library
actually is, this would break, but it is easy to add it back when
we find such a system.
- The object file compat/zlib-uncompress2.o is always compiled and
archived in libgit.a, just like a few other compat/ object files
already are.
- The inclusion of <zlib.h> is done in <git-compat-util.h>; we used
to do so from <cache.h> which includes <git-compat-util.h> as the
first thing it does, so from the *.c codes, there is no practical
change.
- Until objects in libgit.a that is already used gains a reference
to the function, the reftable code will be the only one that
wants it, so libgit.a on the linker command line needs to appear
once more at the end to satisify the mutual dependency.
- Beat found a trick used by OpenSSL to avoid making the
conditionally-compiled object truly empty (apparently because
they had to deal with compilers that do not want to see an
effectively empty input file). Our compat/zlib-uncompress2.c
file borrows the same trick for portabilty.

In 9a5315edfd (Merge branch 'js/patch-mode-in-others-in-c',

interactive mode that could be turned on via the config option
`add.interactive.useBuiltin`.

In 2df2d81ddd (add -i: use the built-in version when

was also enabled via `feature.experimental`. The first version with this

More than a year (and very few bug reports) later, it is time to declare
the built-in implementation mature and to turn it on by default.
We specifically leave the `add.interactive.useBuiltin` configuration in
place, to give users an "escape hatch" in the unexpected case should
they encounter a previously undetected bug in that implementation.

The "linux-clang" and "linux-gcc" jobs both run "make test" twice, but
with different environment variables. Running these in sequence seems
to have been done to work around some constraint on Travis, see
ae59a4e44f (travis: run tests with GIT_TEST_SPLIT_INDEX, 2018-01-07).
By having these run in parallel we'll get jobs that finish much sooner
than they otherwise would have.
We can also simplify the control flow in "ci/run-build-and-tests.sh"
as a result, since we won't run "make test" twice we don't need to run
"make" twice at all, let's default to "make all test" after setting
the variables, and then override it to just "all" for the compile-only
tests.
Add a comment to clarify that new "test" targets should adjust

Change the setup hooks for the CI to use "$runs_on_pool" for the
"$regular" job. Now we won't need as much boilerplate when adding new
jobs to the "regular" matrix, see 956d2e4639 (tests: add a test mode
for SANITIZE=leak, run it in CI, 2021-09-23) for the last such commit.
I.e. now instead of needing to enumerate each jobname when we select
packages we can install things depending on the pool we're running
in.
That we didn't do this dates back to the now gone dependency on Travis
CI, but even if we add a new CI target in the future this'll be easier
to port over, since we can probably treat "ubuntu-latest" as a
stand-in for some recent Linux that can run "apt" commands.

Remove support for running the CI in travis. The last builds in it are
from 5 months ago[1] (as of 2021-11-19), and our documentation has
referred to GitHub CI instead since f003a91f5c (SubmittingPatches:
replace discussion of Travis with GitHub Actions, 2021-07-22).
We'll now run the "t9810 t9816" and tests on OSX. We didn't before, as
we'd carried the Travis exclusion of them forward from
522354d70f (Add Travis CI support, 2015-11-27). Let's hope whatever
issue there was with them was either Travis specific, or fixed since
then (I'm not sure).
The "apt-add-repository" invocation (which we were doing in GitHub CI)
isn't needed, it was another Travis-only case that was carried forward
into more general code. See 0f0c51181d (travis-ci: install packages
in 'ci/install-dependencies.sh', 2018-11-01).
Remove the "linux-gcc-4.8" job added in fb9d7431cf (travis-ci: build

As described in https://trojansource.codes/trojan-source.pdf, it is
possible to abuse directional formatting (a feature of Unicode) to
deceive human readers into interpreting code differently from compilers.
For example, an "if ()" expression could be enclosed in a comment, but
rendered as if it was outside of that comment. In effect, this could
fool a reviewer into misinterpreting the code flow as benign when it is
not.
It is highly unlikely that Git's source code wants to contain such
directional formatting in the first place, so let's just disallow it.

While git can be compiled with SANITIZE=leak, we have not run
regression tests under that mode. Memory leaks have only been fixed as
one-offs without structured regression testing.
This change adds CI testing for it. We'll now build and small set of
whitelisted t00*.sh tests under Linux with a new job called
"linux-leaks".
The CI target uses a new GIT_TEST_PASSING_SANITIZE_LEAK=true test
mode. When running in that mode, we'll assert that we were compiled
with SANITIZE=leak. We'll then skip all tests, except those that we've
opted-in by setting "TEST_PASSES_SANITIZE_LEAK=true".
A test setting "TEST_PASSES_SANITIZE_LEAK=true" setting can in turn
make use of the "SANITIZE_LEAK" prerequisite, should they wish to
selectively skip tests even under
"GIT_TEST_PASSING_SANITIZE_LEAK=true". In the preceding commit we
started doing this in "t0004-unwritable.sh" under SANITIZE=leak, now
it'll combine nicely with "GIT_TEST_PASSING_SANITIZE_LEAK=true".
This is how tests that don't set "TEST_PASSES_SANITIZE_LEAK=true" will
be skipped under GIT_TEST_PASSING_SANITIZE_LEAK=true:
$ GIT_TEST_PASSING_SANITIZE_LEAK=true ./t0001-init.sh
1..0 # SKIP skip all tests in t0001 under SANITIZE=leak, TEST_PASSES_SANITIZE_LEAK not set
The intent is to add more TEST_PASSES_SANITIZE_LEAK=true annotations
as follow-up change, but let's start small to begin with.
In ci/run-build-and-tests.sh we make use of the default "*" case to
run "make test" without any GIT_TEST_* modes. SANITIZE=leak is known
to fail in combination with GIT_TEST_SPLIT_INDEX=true in
t0016-oidmap.sh, and we're likely to have other such failures in
various GIT_TEST_* modes. Let's focus on getting the base tests
passing, we can expand coverage to GIT_TEST_* modes later.
It would also be possible to implement a more lightweight version of
this by only relying on setting "LSAN_OPTIONS". See
<YS9OT/pn5rRK9cGB@coredump.intra.peff.net>[1] and
<YS9ZIDpANfsh7N+S@coredump.intra.peff.net>[2] for a discussion of
that. I've opted for this approach of adding a GIT_TEST_* mode instead
because it's consistent with how we handle other special test modes.
Being able to add a "!SANITIZE_LEAK" prerequisite and calling
"test_done" early if it isn't satisfied also means that we can more
incrementally add regression tests without being forced to fix
widespread and hard-to-fix leaks at the same time.
We have tests that do simple checking of some tool we're interested
in, but later on in the script might be stressing trace2, or common
sources of leaks like "git log" in combination with the tool (e.g. the
commit-graph tests). To be clear having a prerequisite could also be
accomplished by using "LSAN_OPTIONS" directly.
On the topic of "LSAN_OPTIONS": It would be nice to have a mode to
aggregate all failures in our various scripts, see [2] for a start at
doing that which sets "log_path" in "LSAN_OPTIONS". I've punted on
that for now, it can be added later.
As of writing this we've got major regressions between master..seen,
i.e. the t000*.sh tests and more fixed since 31f9acf9ce (Merge branch
'ah/plugleaks', 2021-08-04) have regressed recently.
See the discussion at <87czsv2idy.fsf@evledraar.gmail.com>[3] about
the lack of this sort of test mode, and 0e5bba53af (add UNLEAK
annotation for reducing leak false positives, 2017-09-08) for the
initial addition of SANITIZE=leak.
See also 09595ab381 (Merge branch 'jk/leak-checkers', 2017-09-19),
7782066f67 (Merge branch 'jk/apache-lsan', 2019-05-19) and the recent
936e58851a (Merge branch 'ah/plugleaks', 2021-05-07) for some of the
past history of "one-off" SANITIZE=leak (and more) fixes.
As noted in [5] we can't support this on OSX yet until Clang 14 is
released, at that point we'll probably want to resurrect that
"osx-leaks" job.

"git-svn" tests assumed that "locale -a", which is used to pick an
available UTF-8 locale, is available everywhere. A knob has been
introduced to allow testers to specify a suitable locale to use.
* dd/svn-test-wo-locale-a:
t: use user-specified utf-8 locale for testing svn
In some test-cases, UTF-8 locale is required. To find such locale,
we're using the first available UTF-8 locale that returned by
"locale -a".
However, the locale(1) utility is unavailable on some systems,
e.g. Linux with musl libc.
However, without "locale -a", we can't guess provided UTF-8 locale.
Add a Makefile knob GIT_TEST_UTF8_LOCALE and activate it for
linux-musl in our CI system.
Rename t/lib-git-svn.sh:prepare_a_utf8_locale to prepare_utf8_locale,
since we no longer prepare the variable named "a_utf8_locale",
but set up a fallback value for GIT_TEST_UTF8_LOCALE instead.
The fallback will be LC_ALL, LANG environment variable,
or the first UTF-8 locale from output of "locale -a", in that order.

make_transient_cache_entry(): optionally alloc from mem_pool
We already have tests for the basic parallel-checkout operations. But
this code can also run be executed by other commands, such as
git-read-tree and git-sparse-checkout, which are currently not tested
with multiple workers. To promote a wider test coverage without
duplicating tests:
1. Add the GIT_TEST_CHECKOUT_WORKERS environment variable, to optionally
force parallel-checkout execution during the whole test suite.
2. Set this variable (with a value of 2) in the second test round of our
linux-gcc CI job. This round runs `make test` again with some
optional GIT_TEST_* variables enabled, so there is no additional
overhead in exercising the parallel-checkout code here.
Note that tests checking out less than two parallel-eligible entries
will fall back to the sequential mode. Nevertheless, it's still a good
exercise for the parallel-checkout framework as the fallback codepath
also writes the queued entries using the parallel-checkout functions
(only without spawning any worker).

A subsequent commit will remove GETTEXT_POISON entirely, let's start
by removing the CI jobs that enable the option.
We cannot just remove the job because the CI is implicitly depending
on the "poison" job being a sort of "default" job in the sense that
it's the job that was otherwise run with the default compiler, no
other GIT_TEST_* options etc. So let's keep it under the name
"linux-gcc-default".
This means we can remove the initial "make test" from the "linux-gcc"
job (it does another one after setting a bunch of GIT_TEST_*
variables).
I'm not doing that because it would conflict with the in-flight
334afbc76f (tests: mark tests relying on the current default for
`init.defaultBranch`, 2020-11-18) (currently on the "seen" branch, so
the SHA-1 will almost definitely change). It's going to use that "make
test" again for different reasons, so let's preserve it for now.

In addition to the manual adjustment to let the `linux-gcc` CI job run
the test suite with `master` and then with `main`, this patch makes sure
that GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME is set in all test scripts
that currently rely on the initial branch name being `master by default.
To determine which test scripts to mark up, the first step was to
force-set the default branch name to `master` in
- all test scripts that contain the keyword `master`,
- t4211, which expects `t/t4211/history.export` with a hard-coded ref to
initialize the default branch,
- t5560 because it sources `t/t556x_common` which uses `master`,
- t8002 and t8012 because both source `t/annotate-tests.sh` which also
uses `master`)
This trick was performed by this command:
$ sed -i '/^ *\. \.\/\(test-lib\|lib-\(bash\|cvs\|git-svn\)\|gitweb-lib\)\.sh$/i\
GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=master\
export GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME\
' $(git grep -l master t/t[0-9]*.sh) \
t/t4211*.sh t/t5560*.sh t/t8002*.sh t/t8012*.sh
After that, careful, manual inspection revealed that some of the test
scripts containing the needle `master` do not actually rely on a
specific default branch name: either they mention `master` only in a
comment, or they initialize that branch specificially, or they do not
actually refer to the current default branch. Therefore, the
aforementioned modification was undone in those test scripts thusly:
$ git checkout HEAD -- \
t/t0027-auto-crlf.sh t/t0060-path-utils.sh \
t/t1011-read-tree-sparse-checkout.sh \

We excluded one set of test scripts in these commands, though: the range
of `git p4` tests. The reason? `git p4` stores the (foreign) remote
branch in the branch called `p4/master`, which is obviously not the
default branch. Manual analysis revealed that only five of these tests
actually require a specific default branch name to pass; They were
modified thusly:
$ sed -i '/^ *\. \.\/lib-git-p4\.sh$/i\
GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=master\
export GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME\

When `master` is tagged, and then both `master` and the tag are pushed,
Travis CI will happily build both. That is a waste of energy, which is
why we skip the build for `master` in that case.
Our GitHub workflow is also triggered by tags. However, the run would
fail because the `windows-test` jobs are _not_ skipped on tags, but the
`windows-build` job _is skipped (and therefore fails to upload the
build artifacts needed by the test jobs).
In addition, we just added logic to our GitHub workflow that will skip
runs altogether if there is already a successful run for the same commit
or at least for the same tree.
Let's just change the GitHub workflow to no longer specifically skip
tagged revisions.

Since e4597aae65 (run test suite without dashed git-commands in PATH,
2009-12-02), we stopped running our tests with `git-foo` binaries found
at the top-level directory of a freshly built source tree; instead we
have placed only `git` and selected `git-foo` commands that must be on
`$PATH` in `bin-wrappers/` and prepended that `bin-wrappers/` to the
`PATH` used in the test suite. We did that to catch the tests and
scripted Git commands that still try to use the dashed form.
Since CI jobs will not install the built Git to anywhere, and the
hardlinks we make at the top-level of the source tree for `git-add` and
friends are not even used during tests, they are pure waste of resources
these days.
Thanks to the newly invented `SKIP_DASHED_BUILT_INS` knob, we can now
skip creating these links in the source tree. So let's do that.
Note that this change introduces a subtle change of behavior: when Git's
`cmd_main()` calls `setup_path()`, it inserts the value of
`GIT_EXEC_PATH` (defaulting to `<prefix>/libexec/git-core`) at the
beginning of the environment variable `PATH`. This is necessary to find
e.g. scripted commands that are installed in that location. For the
purposes of Git's test suite, the `bin-wrappers/` scripts override
`GIT_EXEC_PATH` to point to the top-level directory of the source code.
In other words, if a scripted command had used a dashed invocation of a
built-in Git command, it would not have been caught previously, which is
fixed by this change.

Now that we have Git supporting SHA-256, we'd like to make sure that we
don't regress that state. Unfortunately, it's easy to do so, so to
help, let's add code to run one of our CI jobs with SHA-256 as the
default hash. This will help us detect any problems that may occur.
We pick the linux-clang job because it's relatively fast and the
linux-gcc job already runs the testsuite twice. We want our tests to
run as fast as possible, so we wouldn't want to add a third run to the
linux-gcc job. To make sure we properly exercise the code, let's run
the tests in the default mode (SHA-1) first and then run a second time
with SHA-256. We explicitly specify SHA-1 for the first run so that if
we change the default in the future, we make sure to test both cases.

In our test suite, when 'git p4' invokes a Git command as a
subprocesses, then it should run the 'git' binary we are testing.
Unfortunately, this is not the case in the 'linux-clang' and
'linux-gcc' jobs on Travis CI, where 'git p4' runs the system
'/usr/bin/git' instead.
Travis CI's default Linux image includes 'pyenv', and all Python
invocations that involve PATH lookup go through 'pyenv', e.g. our
'PYTHON_PATH=$(which python3)' sets '/opt/pyenv/shims/python3' as
PYTHON_PATH, which in turn will invoke '/usr/bin/python3'. Alas, the
'pyenv' version included in this image is buggy, and prepends the
directory containing the Python binary to PATH even if that is a
system directory already in PATH near the end. Consequently, 'git p4'
in those jobs ends up with its PATH starting with '/usr/bin', and then
runs '/usr/bin/git'.
So use the absolute paths '/usr/bin/python{2,3}' explicitly when
setting PYTHON_PATH in those Linux jobs to avoid the PATH lookup and
thus the bogus 'pyenv' from interfering with our 'git p4' tests.
Don't bother with special-casing Travis CI: while this issue doesn't
affect the corresponding Linux jobs on GitHub Actions, both CI systems
use Ubuntu LTS-based images, so we can safely rely on these Python
paths.

Depending on the workflows of individual developers, it can either be
convenient or annoying that our GitHub Actions CI jobs are run on every
branch. As an example of annoying: if you carry many half-finished
work-in-progress branches and rebase them frequently against master,
you'd get tons of failure reports that aren't interesting (not to
mention the wasted CPU).
This commit adds a new job which checks a special branch within the
repository for CI config, and then runs a shell script it finds there to
decide whether to skip the rest of the tests. The default will continue
to run tests for all refs if that branch or script is missing.
There have been a few alternatives discussed:
One option is to carry information in the commit itself about whether it
should be tested, either in the tree itself (changing the workflow YAML
file) or in the commit message (a "[skip ci]" flag or similar). But
these are frustrating and error-prone to use:
- you have to manually apply them to each branch that you want to mark
- it's easy for them to leak into other workflows, like emailing patches
We could likewise try to get some information from the branch name. But
that leads to debates about whether the default should be "off" or "on",
and overriding still ends up somewhat awkward. If we default to "on",
you have to remember to name your branches appropriately to skip CI. And
if "off", you end up having to contort your branch names or duplicate
your pushes with an extra refspec.
By comparison, this commit's solution lets you specify your config once
and forget about it, and all of the data is off in its own ref, where it
can be changed by individual forks without touching the main tree.
There were a few design decisions that came out of on-list discussion.
I'll summarize here:
- we could use GitHub's API to retrieve the config ref, rather than a
real checkout (and then just operate on it via some javascript). We
still have to spin up a VM and contact GitHub over the network from
it either way, so it ends up not being much faster. I opted to go
with shell to keep things similar to our other tools (and really
could implement allow-refs in any language you want). This also makes
it easy to test your script locally, and to modify it within the
context of a normal git.git tree.
- we could keep the well-known refname out of refs/heads/ to avoid
cluttering the branch namespace. But that makes it awkward to
manipulate. By contrast, you can just "git checkout ci-config" to
make changes.
- we could assume the ci-config ref has nothing in it except config
(i.e., a branch unrelated to the rest of git.git). But dealing with
orphan branches is awkward. Instead, we'll do our best to efficiently
check out only the ci/config directory using a shallow partial clone,
which allows your ci-config branch to be just a normal branch, with
your config changes on top.
- we could provide a simpler interface, like a static list of ref
patterns. But we can't get out of spinning up a whole VM anyway, so
we might as well use that feature to make the config as flexible as
possible. If we add more config, we should be able to reuse our
partial-clone to set more outputs.

This commit adds build steps that are only executed when tests failed,
uploading the relevant information as build artifacts. These artifacts

Once upon a time we ran 'make --jobs=2 ...' to build Git, its
documentation, or to apply Coccinelle semantic patches. Then commit
eaa62291ff (ci: inherit --jobs via MAKEFLAGS in run-build-and-tests,
2019-01-27) came along, and started using the MAKEFLAGS environment
variable to centralize setting the number of parallel jobs in
'ci/libs.sh'. Alas, it forgot to update 'ci/run-linux32-docker.sh' to
make MAKEFLAGS available inside the Docker container running the 32
bit Linux job, and, consequently, since then that job builds Git
sequentially, and it ignores any Makefile knobs that we might set in
MAKEFLAGS (though we don't set any for the 32 bit Linux job at the
moment).
So update the 'docker run' invocation in 'ci/run-linux32-docker.sh' to
make MAKEFLAGS available inside the Docker container as well. Set
CC=gcc for the 32 bit Linux job, because that's the compiler installed
in the 32 bit Linux Docker image that we use (Travis CI nowadays sets
CC=clang by default, but clang is not installed in this image).

ci(osx): update homebrew-cask repository with less noise
Our 'osx-gcc' build job on Travis CI relied on GCC 8 being installed
(but not linked) in the image we use [1]. Alas, since the last update
of this image a few days ago this is not the case anymore, and now it
contains GCC 9 (installed and linked) instead of GCC 8. The results
are failed 'osx-gcc' jobs, because they can't find the 'gcc-8' command
[2].
Let's move on to use GCC 9, with hopefully better error reporting and
improved -Wfoo flags and what not. On Travis CI this has the benefit
that we can spare a few seconds while installing dependencies, because
it already comes pre-installed, at least for now. The Azure Pipelines
OSX image doesn't include GCC, so we have to install it ourselves
anyway, and then we might as well install the newer version.
In a vain attempt I tried to future-proof this a bit:
- Install 'gcc@9' specifically, so we'll still get what we want even
after GCC 10 comes out, and the "plain" 'gcc' package starts to
refer to 'gcc@10'.
- Run both 'brew install gcc@9' and 'brew link gcc@9'. If 'gcc@9'
is already installed and linked, then both commands are noop and
exit with success. But as we saw in the past, sometimes the image
contains the expected GCC package installed but not linked, so
maybe it will happen again in the future as well. In that case
'brew install' is still a noop, and instructs the user to run
'brew link' instead, so that's what we'll do. And if 'gcc@9' is
not installed, then 'brew install' will install it, and the
subsequent 'brew link' becomes a noop.
An additional benefit of this patch is that from now on we won't
unnecessarily install GCC and its dependencies in the 'osx-clang' jobs
on Azure Pipelines.

A few days ago Travis CI updated their existing OSX images, including

then installing dependencies in the 'osx-gcc' job fails when it tries
to link gcc@8:

GCC8 is still installed but not linked to '/usr/local' in the updated
image, as it was before this update, but now we have to link it by
running 'brew link gcc'. So let's do that then, and fall back to
linking gcc@8 if it doesn't, just to be sure.
Our builds on Azure Pipelines are unaffected by this issue. The OSX
image over there doesn't contain the gcc@8 package, so we have to
'brew install' it, which already takes care of linking it to
'/usr/local'. After that the 'brew link gcc' command added by this
patch fails, but the ||-chained fallback 'brew link gcc@8' command

The Azure Pipelines builds are failing for macOS due to a change in the
location of the perforce cask. The command outputs the following error:
+ brew install caskroom/cask/perforce
Error: caskroom/cask was moved. Tap homebrew/cask-cask instead.
So let's try to call `brew cask install perforce` first (which is what
that error message suggests, in a most round-about way).
Prior to 672f51cb we used to install the 'perforce' package with 'brew
install perforce' (note: no 'cask' in there). The justification for
672f51cb was that the command 'brew install perforce' simply stopped
working, after Homebrew folks decided that it's better to move the
'perforce' package to a "cask". Their justification for this move was
that 'brew install perforce' "can fail due to a checksum mismatch ...",
and casks can be installed without checksum verification. And indeed,
both 'brew cask install perforce' and 'brew install
caskroom/cask/perforce' printed something along the lines of:
==> No checksum defined for Cask perforce, skipping verification
It is unclear why 672f51cb used 'brew install caskroom/cask/perforce'
instead of 'brew cask install perforce'. It appears (by running both
commands on old Travis CI macOS images) that both commands worked all
the same already back then.
In any case, as the error message at the top of this commit message
shows, 'brew install caskroom/cask/perforce' has stopped working
recently, but 'brew cask install perforce' still does, so let's use
that.
CI servers are typically fresh virtual machines, but not always. To
accommodate for that, let's try harder if `brew cask install perforce`
fails, by specifically pulling the latest `master` of the
`homebrew-cask` repository.
This will still fail, of course, when `homebrew-cask` falls behind
Perforce's release schedule. But once it is updated, we can now simply
re-run the failed jobs and they will pick up that update.
As for updating `homebrew-cask`: the beginnings of automating this in
https://dev.azure.com/gitgitgadget/git/_build?definitionId=11&_a=summary
will be finished once the next Perforce upgrade comes around.

Travis CI offers shell access to its virtual machine environment
running the build jobs, called "debug mode" [1]. After restarting a
build job in debug mode and logging in, the first thing I usually do
is to install dependencies, i.e. run './ci/install-dependencies.sh'.
This works just fine when I restarted a failed build job in debug
mode. However, after restarting a successful build job in debug mode
our CI scripts get all clever, and exit without doing anything useful,
claiming that "This commit's tree has already been built and tested

building and testing already known good trees in "regular" CI builds.
In debug mode, however, this is a nuisiance, because one has to delete
the cache (or at least the 'good-trees' file in the cache) to proceed.
Let's update our CI scripts, in particular the common 'ci/lib.sh', to
not skip previously successfully built and tested trees in debug mode,
so all those scripts will do what there were supposed to do even when
a successful build job was restarted in debug mode.

Our documentation toolchain has traditionally been built around DocBook
4.5. This version of DocBook is the last DTD-based version of DocBook.
In 2009, DocBook 5 was introduced using namespaces and its syntax is
expressed in RELAX NG, which is more expressive and allows a wider
variety of syntax forms.
Asciidoctor, one of the alternatives for building our documentation,
moved support for DocBook 4.5 out of core in its recent 2.0 release and
now only supports DocBook 5 in the main release. The DocBoook 4.5
converter is still available as a separate component, but this is not
available in most distro packages. This would not be a problem but for
the fact that we use xmlto, which is still stuck in the DocBook 4.5 era.
xmlto performs DTD validation as part of the build process. This is not
problematic for DocBook 4.5, which has a valid DTD, but it clearly
cannot work for DocBook 5, since no DTD can adequately express its full
syntax. In addition, even if xmlto did support RELAX NG validation,
that wouldn't be sufficient because it uses the libxml2-based xmllint to
do so, which has known problems with validating interleaves in RELAX NG.
Fortunately, there's an easy way forward: ask Asciidoctor to use its
DocBook 5 backend and tell xmlto to skip validation. Asciidoctor has
supported DocBook 5 since v0.1.4 in 2013 and xmlto has supported
skipping validation for probably longer than that.
We also need to teach xmlto how to use the namespaced DocBook XSLT
stylesheets instead of the non-namespaced ones it usually uses.
Normally these stylesheets are interchangeable, but the non-namespaced
ones have a bug that causes them not to strip whitespace automatically
from certain elements when namespaces are in use. This results in
additional whitespace at the beginning of list elements, which is
jarring and unsightly.
We can do this by passing a custom stylesheet with the -x option that
simply imports the namespaced stylesheets via a URL. Any system with
support for XML catalogs will automatically look this URL up and
reference a local copy instead without us having to know where this
local copy is located. We know that anyone using xmlto will already
have catalogs set up properly since the DocBook 4.5 DTD used during
validation is also looked up via catalogs. All major Linux
distributions distribute the necessary stylesheets and have built-in
catalog support, and Homebrew does as well, albeit with a requirement to
set an environment variable to enable catalog support.
On the off chance that someone lacks support for catalogs, it is
possible for xmlto (via xmllint) to download the stylesheets from the
URLs in question, although this will likely perform poorly enough to
attract attention. People still have the option of using the prebuilt
documentation that we ship, so happily this should not be an impediment.
Finally, we need to filter out some messages from other stylesheets that
occur when invoking dblatex in the CI job. This tool strips namespaces
much like the unnamespaced DocBook stylesheets and prints similar
messages. If we permit these messages to be printed to standard error,
our documentation CI job will fail because we check standard error for
unexpected output. Due to dblatex's reliance on Python 2, we may need
to revisit its use in the future, in which case this problem may go
away, but this can be delayed until a future patch.
The final message we filter is due to libxslt on modern Debian and
Ubuntu. The patch which they use to implement reproducible ID
generation also prints messages about the ID generation. While this
doesn't affect our current CI images since they use Ubuntu 16.04 which
lacks this patch, if we upgrade to Ubuntu 18.04 or a modern Debian,
these messages will appear and, like the above messages, cause a CI
failure.

Once upon a time GIT_TEST_HTTPD was a tristate variable and we
exported 'GIT_TEST_HTTPD=YesPlease' in our CI scripts to make sure
that we run the httpd tests in the Linux Clang and GCC build jobs, or
error out if they can't be run for any reason [1].

C99 'for' loop initial declaration, i.e. 'for (int i = 0; i < n; i++)',
is not allowed in Git's codebase yet, to maintain compatibility with
some older compilers.
Our Travis CI builds used to catch 'for' loop initial declarations,
because the GETTEXT_POISON job has always built Git with the default
'cc', which in Travis CI's previous default Linux image (based on
Ubuntu 14.04 Trusty) is GCC 4.8, and that GCC version errors out on
this construct (not only with DEVELOPER=1, but with our default CFLAGS
as well). Alas, that's not the case anymore, becase after 14.04's EOL
Travis CI's current default Linux image is based on Ubuntu 16.04
Xenial [1] and its default 'cc' is now GCC 5.4, which, just like all
later GCC and Clang versions, simply accepts this construct, even if
we don't explicitly specify '-std=c99'.
Ideally we would adjust our CFLAGS used with DEVELOPER=1 to catch this
undesired construct already when contributors build Git on their own
machines. Unfortunately, however, there seems to be no compiler
option that would catch only this particular construct without choking
on many other things, e.g. while a later compiler with '-std=c90'
and/or '-ansi' does catch this construct, it can't build Git because
of several screenfulls of other errors.
Add the 'linux-gcc-4.8' job to Travis CI, in order to build Git with
GCC 4.8, and thus to timely catch any 'for' loop initial declarations.
To catch those it's sufficient to only build Git with GCC 4.8, so
don't run the test suite in this job, because 'make test' takes rather
long [2], and it's already run five times in other jobs, so we
wouldn't get our time's worth.
[1] The Azure Pipelines builds have been using Ubuntu 16.04 images
from the start, so I belive they never caught 'for' loop initial
declarations.
[2] On Travis CI 'make test' alone would take about 9 minutes in this
new job (without running httpd, Subversion, and P4 tests). For
comparison, starting the job and building Git with GCC 4.8 takes
only about 2 minutes.

Lately our GCC macOS build job on Travis CI has been erroring out
while installing dependencies with:
+brew link gcc@8
Error: No such keg: /usr/local/Cellar/gcc@8
The command "ci/install-dependencies.sh" failed and exited with 1 during .
Now, while gcc@8 is still pre-installed (but not linked) and would be
perfectly usable in the Travis CI macOS image we use [1], it's at
version 8.2. However, when installing dependencies we first
explicitly run 'brew update', which spends over two minutes to update
itself and information about the available packages, and it learns
about GCC 8.3. After that point gcc@8 exclusively refers to v8.3,
and, unfortunately, 'brew' is just too dumb to be able to do anything
with the still installed 8.2 package, and the subsequent 'brew link
gcc@8' fails. (Even 'brew uninstall gcc@8' fails with the same
error!)
Don't run 'brew update' to keep the already installed GCC 8.2 'brew
link'-able. Note that in addition we have to 'export
HOMEBREW_NO_AUTO_UPDATE=1' first, because 'brew' is so very helpful
that it would implicitly run update for us on the next 'brew install
<pkg>' otherwise.
Disabling 'brew update' has additional benefits:
- It shaves off 2-3mins from the ~4mins currently spent on
installing dependencies, and the macOS build jobs have always been
prone to exceeding the time limit on Travis CI.
- Our builds won't suddenly break because of the occasional Homebrew
breakages [2].
The drawback is that we'll be stuck with slightly older versions of
the packages that we install via Homebrew (Git-LFS 2.5.2 and Perforce
2018.1; they are currently at 2.7.2 and 2019.1, respectively). We
might want to reconsider this decision as time goes on and/or switch

Change the GIT_TEST_GETTEXT_POISON variable from being "non-empty?" to
being a more standard boolean variable.
Since it needed to be checked in both C code and shellscript (via test
-n) it was one of the remaining shellscript-like variables. Now that
we have "env--helper" we can change that.
There's a couple of tricky edge cases that arise because we're using
git_env_bool() early, and the config-reading "env--helper".
If GIT_TEST_GETTEXT_POISON is set to an invalid value die_bad_number()
will die, but to do so it would usually call gettext(). Let's detect
the special case of GIT_TEST_GETTEXT_POISON and always emit that
message in the C locale, lest we infinitely loop.
As seen in the updated tests in t0017-env-helper.sh there's also a
caveat related to "env--helper" needing to read the config for trace2
purposes.
Since the C_LOCALE_OUTPUT prerequisite is lazy and relies on
"env--helper" we could get invalid results if we failed to read the
config (e.g. because we'd loop on includes) when combined with
e.g. "test_i18ngrep" wanting to check with "env--helper" if
GIT_TEST_GETTEXT_POISON was true or not.
I'm crossing my fingers and hoping that a test similar to the one I
removed in the earlier "config tests: simplify include cycle test"
change in this series won't happen again, and testing for this
explicitly in "env--helper"'s own tests.
This change breaks existing uses of
e.g. GIT_TEST_GETTEXT_POISON=YesPlease, which we've documented in
po/README and other places. As noted in [1] we might want to consider
also accepting "YesPlease" in "env--helper" as a special-case.
But as the lack of uproar over 6cdccfce1e ("i18n: make GETTEXT_POISON
a runtime option", 2018-11-08) demonstrates the audience for this
option is a really narrow set of git developers, who shouldn't have
much trouble modifying their test scripts, so I think it's better to
deal with that minor headache now and make all the relevant GIT_TEST_*
variables boolean in the same way than carry the "YesPlease"
special-case forward.

To run tests for Git SVN, our scripts for CI used to install the
git-svn package (in the hope that it would bring in the right
dependencies). This has been updated to install the more direct
dependency, namely, libsvn-perl.
* sg/ci-libsvn-perl:
ci: install 'libsvn-perl' instead of 'git-svn'
Since e7e9f5e7a1 (travis-ci: enable Git SVN tests t91xx on Linux,
2016-05-19) some of our Travis CI build jobs install the 'git-svn'
package, because it was a convenient way to install its dependencies,
which are necessary to run our 'git-svn' tests (we don't actually need
the 'git-svn' package itself). However, from those dependencies,
namely the 'libsvn-perl', 'libyaml-perl', and 'libterm-readkey-perl'
packages, only 'libsvn-perl' is necessary to run those tests, the
others arent, not even to fulfill some prereqs.
So update 'ci/install-dependencies.sh' to install only 'libsvn-perl'
instead of 'git-svn' and its additional dependencies.
Note that this change has more important implications than merely not
installing three unnecessary packages, as it keeps our builds working
with Travis CI's Xenial images. In our '.travis.yml' we never
explicitly specified which Linux image we want to use to run our Linux
build jobs, and so far they have been run on the default Ubuntu 14.04
Trusty image. However, 14.04 just reached its EOL, and Travis CI has
already began the transition to use 16.04 Xenial as the default Linux
build environment [1]. Alas, our Linux Clang and GCC build jobs can't
simply 'apt-get install git-svn' in the current Xenial images [2],
like they did in the Trusty images, and, consequently, fail.
Installing only 'libsvn-perl' avoids this issue, while the 'git svn'
tests are still run as they should.
[1] https://blog.travis-ci.com/2019-04-15-xenial-default-build-environment
[2] 'apt-get install git-svn' in the Xenial image fails with:
The following packages have unmet dependencies:
git-svn : Depends: git (< 1:2.7.4-.)
E: Unable to correct problems, you have held broken packages.
The reason is that both the Trusty and Xenial images contain the
'git' package installed from 'ppa:git-core/ppa', so it's
considerably newer than the 'git' package in the corresponding
standard Ubuntu package repositories. The difference is that the
Trusty image still contains these third-party apt repositories, so
the 'git-svn' package was installed from the same PPA, and its
version matched the version of the already installed 'git'
package. In the Xenial image, however, these third-party
apt-repositories are removed (to reduce the risk of unrelated
interference and faster 'apt-get update') [3], and the version of
the 'git-svn' package coming from the standard Ubuntu package
repositories doesn't match the much more recent version of the
'git' package installed from the PPA, resulting in this dependecy
error.
Adding back the 'ppa:git-core/ppa' package repository would solve
this dependency issue as well, but since the troublesome package
happens to be unnecessary, not installing it in the first place is
better.

In 'ci/test-documentation.sh' we save the standard error of 'make
doc', and, in an attempt to make sure that neither AsciiDoc nor
Asciidoctor printed any warnings, we check the emptiness of the
resulting file with '! test -s stderr.log'. This check has never
actually worked, because in our 'ci/*' build scripts we rely on 'set
-e' aborting the build job when a command exits with error, and,
unfortunately, the combination of the two doesn't work as intended.
According to POSIX [1]:
"The -e setting shall be ignored when executing [...] a pipeline
beginning with the ! reserved word" [2]
Watch and learn:
$ echo unexpected >file
$ ( set -e; ! test -s file ; echo "should not reach this" ) ; echo $?
should not reach this
0
This is why we haven't noticed the warnings from Asciidoctor that were
fixed in the first patches of this patch series, though some of them
were already there in the build of v2.18.0-rc0 [3].
Check the emptiness of that file with 'test ! -s' instead, which works
properly with 'set -e':
$ ( set -e; test ! -s file ; echo "should not reach this" ) ; echo $?
1
Furthermore, dump the contents of that file to the log for our
convenience, so if it were to unexpectedly end up being non-empty,
then we wouldn't have to scroll through all that long build log
looking for warnings, but could see them right away near the end of
the log.
Note that we are only really interested in the standard error of
AsciiDoc and Asciidoctor, but by saving the stderr of 'make doc' we
also save any error output from the make rules. Currently there is
only one such line: we build the docs with Asciidoctor right after a
'make clean', meaning that 'make USE_ASCIIDOCTOR=1 doc' always starts
with running 'GIT-VERSION-GEN', which in turn prints the version to
stderr. A 'sed' command was supposed to remove this version line to
prevent it from triggering that (previously defunct) emptiness check,
but, unfortunately, this command doesn't work as intended, either,
because it leaves the file to be checked intact, but that defunct
emptiness check hid this issue, too... Furthermore, in the near
future there will be an other line on stderr, because commit
9a71722b4d (Doc: auto-detect changed build flags, 2019-03-17) in the
currently cooking branch 'ma/doc-diff-doc-vs-doctor-comparison' will
print "* new asciidoc flags" at the beginning of both 'make doc'
invokations.
Extend that 'sed' command to remove this line, too, wrap it in a
helper function so the output of both 'make doc' is filtered the same
way, and change its invokation to actually write the logfile to be
checked.

[2] POSIX doesn't discuss the meaning of '! cmd' in case of simple

more commands separated by the control operator '|'", so
apparently a simple command is considered as pipeline as well.

Commit 2c8921db2b (travis-ci: build with the right compiler,

to build Git. A bit later, and in a different topic branch commit
eaa62291ff (ci: inherit --jobs via MAKEFLAGS in run-build-and-tests,
2019-01-27) started to use MAKEFLAGS as well. Unfortunately, there is
a semantic conflict between these two commits: both of them set
MAKEFLAGS, and since the line adding CC from 2c8921db2b comes later in
'ci/lib.sh', it overwrites the number of parallel jobs added in
eaa62291ff.
Consequently, since both commits have been merged all our CI jobs have
been building Git, building its documentation, and applying semantic
patches sequentially, making all build jobs a bit slower. Running
the test suite is unaffected, because the number of test jobs comes
from GIT_PROVE_OPTS.
Append to MAKEFLAGS when setting the compiler to use, to ensure that
the number of parallel jobs to use is preserved.

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).

This commit adds an azure-pipelines.yml file which is Azure DevOps'
equivalent to Travis CI's .travis.yml.
The main idea is to replicate the Travis configuration as faithfully as
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.)

Because Azure Pipeline's macOS agents already have git-lfs and gettext

The upcoming patches will allow building git.git via Azure Pipelines
(i.e. Azure DevOps' Continuous Integration), where variable names and
URLs look a bit different than in Travis CI.
Also, the configurations of the available agents are different. For
example, Travis' and Azure Pipelines' macOS agents are set up
differently, so that on Travis, we have to install the git-lfs and
gettext Homebrew packages, and on Azure Pipelines we do not need to.
Likewise, Azure Pipelines' Ubuntu agents already have asciidoctor
installed.
Finally, on Azure Pipelines the natural way is not to base64-encode tar
files of the trash directories of failed tests, but to publish build
artifacts instead. Therefore, that code to log those base64-encoded tar
files is guarded to be Travis-specific.

When building a PR, TRAVIS_BRANCH refers to the *target branch*.
Therefore, if a PR targets `master`, and `master` happened to be tagged,
we skipped the build by mistake.
Fix this by using TRAVIS_PULL_REQUEST_BRANCH (i.e. the *source branch*)
when available, falling back to TRAVIS_BRANCH (i.e. for CI builds, also
known as "push builds").
Let's give it a new variable name, too: CI_BRANCH (as it is different
from TRAVIS_BRANCH). This also prepares for the upcoming patches which
will make our ci/* code a bit more independent from Travis and open it

Our 'Makefile' hardcodes the compiler to build Git as 'CC = cc'. This
CC variable can be overridden from the command line, i.e. 'make
CC=gcc-X.Y' will build with that particular GCC version, but not from
the environment, i.e. 'CC=gcc-X.Y make' will still build with whatever
'cc' happens to be on the platform.
Our build jobs on Travis CI are badly affected by this. In the build
matrix we have dedicated build jobs to build Git with GCC and Clang
both on Linux and macOS from the very beginning (522354d70f (Add
Travis CI support, 2015-11-27)). Alas, this never really worked as
supposed to, because Travis CI specifies the compiler for those build
jobs as 'export CC=gcc' and 'export CC=clang' (which works fine for
projects built with './configure && make'). Consequently, our
'linux-clang' build job has always used GCC, because that's where 'cc'
points at in Travis CI's Linux images, while the 'osx-gcc' build job
has always used Clang. Furthermore, 37fa4b3c78 (travis-ci: run gcc-8
on linux-gcc jobs, 2018-05-19) added an 'export CC=gcc-8' in an
attempt to build with a more modern compiler, but to no avail.
Set MAKEFLAGS with CC based on the $CC environment variable, so 'make'
will run the "right" compiler. The Xcode 10.1 macOS image on Travis
CI already contains the gcc@8 package from Homebrew, but we have to
'brew link' it first to be able to use it.
So with this patch our build jobs will build Git with the following
compiler versions:
linux-clang: clang version 5.0.0 (tags/RELEASE_500/final)
linux-gcc: gcc-8 (Ubuntu 8.1.0-5ubuntu1~14.04) 8.1.0
osx-clang: Apple LLVM version 10.0.0 (clang-1000.11.45.5)

All Travis CI build jobs run the test suite with 'make --quiet test'.
On one hand, being quiet doesn't save us from much clutter in the
output:
$ make test |wc -l
861
$ make --quiet test |wc -l
848
It only spares 13 lines, mostly the output of entering the 't/'
directory and the pre- and post-cleanup commands, which is negligible
compared to the ~700 lines printed while building Git and the ~850
lines of 'prove' output.
On the other hand, it's asking for trouble. In our CI build scripts
we build Git and run the test suite in two separate 'make'
invocations. In a prelimiary version of one of the later patches in
this series, to explicitly specify which compiler to use, I changed
them to basically run:
make CC=$CC
make --quiet test
naively thinking that it should Just Work... but then that 'make
--quiet test' got all clever on me, noticed the changed build flags,
and then proceeded to rebuild everything with the default 'cc'. And
because of that '--quiet' option, it did so, well, quietly, only
saying "* new build flags", and it was by mere luck that I happened to
notice that something is amiss.
Let's just drop that '--quiet' option when running the test suite in
all build scripts.

Our testing framework uses a special i18n "poisoned localization"
feature to find messages that ought to stay constant but are
incorrectly marked to be translated. This feature has been made
into a runtime option (it used to be a compile-time option).
* ab/dynamic-gettext-poison:
Makefile: ease dynamic-gettext-poison transition
i18n: make GETTEXT_POISON a runtime option
The procedure to install dependencies before testing at Travis CI
is getting revamped for both simplicity and flexibility, taking
advantage of the recent move to the vm-based environment.
* sg/travis-install-dependencies:
travis-ci: install packages in 'ci/install-dependencies.sh'
Change the GETTEXT_POISON compile-time + runtime GIT_GETTEXT_POISON
test parameter to only be a GIT_TEST_GETTEXT_POISON=<non-empty?>
runtime parameter, to be consistent with other parameters documented
in "Running tests with special setups" in t/README.
When I added GETTEXT_POISON in bb946bba76 ("i18n: add GETTEXT_POISON
to simulate unfriendly translator", 2011-02-22) I was concerned with
ensuring that the _() function would get constant folded if NO_GETTEXT
was defined, and likewise that GETTEXT_POISON would be compiled out
unless it was defined.
But as the benchmark in my [1] shows doing a one-off runtime
getenv("GIT_TEST_[...]") is trivial, and since GETTEXT_POISON was
originally added the GIT_TEST_* env variables have become the common
idiom for turning on special test setups.
So change GETTEXT_POISON to work the same way. Now the
GETTEXT_POISON=YesPlease compile-time option is gone, and running the
tests with GIT_TEST_GETTEXT_POISON=[YesPlease|] can be toggled on/off
without recompiling.
This allows for conditionally amending tests to test with/without
poison, similar to what 859fdc0c3c ("commit-graph: define
GIT_TEST_COMMIT_GRAPH", 2018-08-29) did for GIT_TEST_COMMIT_GRAPH. Do
some of that, now we e.g. always run the t0205-gettext-poison.sh test.
I did enough there to remove the GETTEXT_POISON prerequisite, but its
inverse C_LOCALE_OUTPUT is still around, and surely some tests using
it can be converted to e.g. always set GIT_TEST_GETTEXT_POISON=.
Notes on the implementation:
* We still compile a dedicated GETTEXT_POISON build in Travis
CI. Perhaps this should be revisited and integrated into the
"linux-gcc" build, see ae59a4e44f ("travis: run tests with
GIT_TEST_SPLIT_INDEX", 2018-01-07) for prior art in that area. Then
again maybe not, see [2].
* We now skip a test in t0000-basic.sh under
GIT_TEST_GETTEXT_POISON=YesPlease that wasn't skipped before. This
test relies on C locale output, but due to an edge case in how the
previous implementation of GETTEXT_POISON worked (reading it from
GIT-BUILD-OPTIONS) wasn't enabling poison correctly. Now it does,
and needs to be skipped.
* The getenv() function is not reentrant, so out of paranoia about
code of the form:
printf(_("%s"), getenv("some-env"));
call use_gettext_poison() in our early setup in git_setup_gettext()
so we populate the "poison_requested" variable in a codepath that's
won't suffer from that race condition.
* We error out in the Makefile if you're still saying
GETTEXT_POISON=YesPlease to prompt users to change their
invocation.
* We should not print out poisoned messages during the test
initialization itself to keep it more readable, so the test library
hides the variable if set in $GIT_TEST_GETTEXT_POISON_ORIG during
setup. See [3].
See also [4] for more on the motivation behind this patch, and the
history of the GETTEXT_POISON facility.

Ever since we started using Travis CI, we specified the list of
packages to install in '.travis.yml' via the APT addon. While running
our builds on Travis CI's container-based infrastructure we didn't
have another choice, because that environment didn't support 'sudo',
and thus we didn't have permission to install packages ourselves. With
the switch to the VM-based infrastructure in the previous patch we do
get a working 'sudo', so we can install packages by running 'sudo
apt-get -y install ...' as well.
Let's make use of this and install necessary packages in
'ci/install-dependencies.sh', so all the dependencies (i.e. both
packages and "non-packages" (P4 and Git-LFS)) are handled in the same
file. Install gcc-8 only in the 'linux-gcc' build job; so far it has
been unnecessarily installed in the 'linux-clang' build job as well.
Print the versions of P4 and Git-LFS conditionally, i.e. only when
they have been installed; with this change even the static analysis
and documentation build jobs start using 'ci/install-dependencies.sh'
to install packages, and neither of these two build jobs depend on and
thus install those.
This change will presumably be beneficial for the upcoming Azure
Pipelines integration [1]: preliminary versions of that patch series
run a couple of 'apt-get' commands to install the necessary packages
before running 'ci/install-dependencies.sh', but with this patch it
will be sufficient to run only 'ci/install-dependencies.sh'.

The commit-graph and multi-pack-index features introduce optional
data structures that are not required for normal Git operations.
It is important to run the normal test suite without them enabled,
but it is helpful to also run the test suite using them.
Our continuous integration scripts include a second test stage that
runs with optional GIT_TEST_* variables enabled. Add the following
two variables to that stage:
GIT_TEST_COMMIT_GRAPH
GIT_TEST_MULTI_PACK_INDEX
This will slow down the operation, as we build a commit-graph file
after every 'git commit' operation and build a multi-pack-index
during every 'git repack' operation. However, it is important that
future changes are compatible with these features.

In a recent update in 2.18 era, "git pack-objects" started
producing a larger than necessary packfiles by missing
opportunities to use large deltas.
* nd/pack-deltify-regression-fix:
pack-objects: fix performance issues on packing large deltas
The Travis CI scripts were taught to ship back the test data from
failed tests.
* sg/travis-retrieve-trash-upon-failure:
travis-ci: include the trash directories of failed tests in the trace log
The trash directory of a failed test might contain invaluable
information about the cause of the failure, but we have no access to
the trash directories of Travis CI build jobs. The only feedback we
get from there is the build job's trace log, so...
Modify 'ci/print-test-failures.sh' to create a tar.gz archive of the
trash directory of each failed test, encode that archive with base64,
and print the resulting block of ASCII text, so it gets embedded in
the trace log. Furthermore, run tests with '--immediate' to
faithfully preserve the failed state.
Extracting the trash directories from the trace log turned out to be a
bit of a hassle, partly because of the size of these logs (usually
resulting in several hundreds or even thousands of lines of
base64-encoded text), and partly because these logs have CRLF, CRCRLF
and occasionally even CRCRCRLF line endings, which cause 'base64 -d'
from coreutils to complain about "invalid input". For convenience add
a small script 'ci/util/extract-trash-dirs.sh', which will extract and
unpack all base64-encoded trash directories embedded in the log fed to
its standard input, and include an example command to be copy-pasted
into a terminal to do it all at the end of the failure report.
A few of our tests create sizeable trash directories, so limit the
size of each included base64-encoded block, let's say, to 1MB. And
just in case something fundamental gets broken and a lot of tests fail
at once, don't include trash directories when the combined size of the
included base64-encoded blocks would exceed 1MB.

Coccinelle's and in turn 'make coccicheck's exit code only indicates
that Coccinelle managed to finish its analysis without any errors
(e.g. no unknown --options, no missing files, no syntax errors in the
semantic patches, etc.), but it doesn't indicate whether it found any
undesired code patterns to transform or not. To find out the latter,
one has to look closer at 'make coccicheck's standard output and look
for lines like:
SPATCH result: contrib/coccinelle/<something>.cocci.patch
And this only indicates that there is something to transform, but to
see what the suggested transformations are one has to actually look
into those '*.cocci.patch' files.
This makes the automated static analysis build job on Travis CI not
particularly useful, because it neither draws our attention to
Coccinelle's findings, nor shows the actual findings. Consequently,
new topics introducing undesired code patterns graduated to master
on several occasions without anyone noticing.
The only way to draw attention in such an automated setting is to fail
the build job. Therefore, modify the 'ci/run-static-analysis.sh'
build script to check all the resulting '*.cocci.patch' files, and
fail the build job if any of them turns out to be not empty. Include
those files' contents, i.e. Coccinelle's suggested transformations, in

Let's start with some background about oe_delta_size() and
oe_set_delta_size(). If you already know, skip the next paragraph.
These two are added in 0aca34e826 (pack-objects: shrink delta_size
field in struct object_entry - 2018-04-14) to help reduce 'struct
object_entry' size. The delta size field in this struct is reduced to
only contain max 1MB. So if any new delta is produced and larger than
1MB, it's dropped because we can't really save such a large size
anywhere. Fallback is provided in case existing packfiles already have
large deltas, then we can retrieve it from the pack.
While this should help small machines repacking large repos without
large deltas (i.e. less memory pressure), dropping large deltas during
the delta selection process could end up with worse pack files. And if
existing packfiles already have >1MB delta and pack-objects is
instructed to not reuse deltas, all of them will be dropped on the
floor, and the resulting pack would be definitely bigger.
There is also a regression in terms of CPU/IO if we have large on-disk
deltas because fallback code needs to parse the pack every time the
delta size is needed and just access to the mmap'd pack data is enough
for extra page faults when memory is under pressure.
Both of these issues were reported on the mailing list. Here's some
numbers for comparison.
Version Pack (MB) MaxRSS(kB) Time (s)
------- --------- ---------- --------
2.17.0 5498 43513628 2494.85
2.18.0 10531 40449596 4168.94
This patch provides a better fallback that is
- cheaper in terms of cpu and io because we won't have to read
existing pack files as much
- better in terms of pack size because the pack heuristics is back to
2.17.0 time, we do not drop large deltas at all
If we encounter any delta (on-disk or created during try_delta phase)
that is larger than the 1MB limit, we stop using delta_size_ field for
this because it can't contain such size anyway. A new array of delta
size is dynamically allocated and can hold all the deltas that 2.17.0
can. This array only contains delta sizes that delta_size_ can't
contain.
With this, we do not have to drop deltas in try_delta() anymore. Of
course the downside is we use slightly more memory, even compared to
2.17.0. But since this is considered an uncommon case, a bit more
memory consumption should not be a problem.
Delta size limit is also raised from 1MB to 16MB to better cover
common case and avoid that extra memory consumption (99.999% deltas in
this reported repo are under 12MB; Jeff noted binary artifacts topped
out at about 3MB in some other private repos). Other fields are
shuffled around to keep this struct packed tight. We don't use more
memory in common case even with this limit update.
A note about thread synchronization. Since this code can be run in
parallel during delta searching phase, we need a mutex. The realloc
part in packlist_alloc() is not protected because it only happens
during the object counting phase, which is always single-threaded.
Access to e->delta_size_ (and by extension
pack->delta_size[e - pack->objects]) is unprotected as before, the
thread scheduler in pack-objects must make sure "e" is never updated
by two different threads.
The area under the new lock is as small as possible, avoiding locking
at all in common case, since lock contention with high thread count
could be expensive (most blobs are small enough that delta compute
time is short and we end up taking the lock very often). The previous
attempt to always hold a lock in oe_delta_size() and
oe_set_delta_size() increases execution time by 33% when repacking
linux.git with with 40 threads.

every time before subsequent executions, or the build script fails.
Make this process more convenient and don't try to create that user if
it already exists and has the right user ID in the container, so
developers don't have to bother with running a 'userdel' each time
before they run the build script.
The build job on Travis CI always starts with a fresh Docker
container, so this change doesn't make a difference there.

Travis CI runs the 32 bit Linux build job in a Docker container, where
all commands are executed as root by default. Therefore, ever since
we added this build job in 88dedd5e7 (Travis: also test on 32-bit
Linux, 2017-03-05), we have a bit of code to create a user in the
container matching the ID of the host user and then to run the test
suite as this user. Matching the host user ID is important, because
otherwise the host user would have no access to any files written by
processes running in the container, notably the logs of failed tests
couldn't be included in the build job's trace log.
Alas, this piece of code never worked, because it sets the variable
holding the user name ($CI_USER) in a subshell, meaning it doesn't
have any effect by the time we get to the point to actually use the
variable to switch users with 'su'. So all this time we were running
the test suite as root.
Reorganize that piece of code in 'ci/run-linux32-build.sh' a bit to
avoid that problematic subshell and to ensure that we switch to the
right user. Furthermore, make the script's optional host user ID
option mandatory, so running the build accidentally as root will
become harder when debugging locally. If someone really wants to run
the test suite as root, whatever the reasons might be, it'll still be
possible to do so by explicitly passing '0' as host user ID.
Finally, one last catch: since commit 7e72cfcee (travis-ci: save prove
state for the 32 bit Linux build, 2017-12-27) the 'prove' test harness
has been writing its state to the Travis CI cache directory from
within the Docker container while running as root. After this patch
'prove' will run as a regular user, so in future build jobs it won't
be able overwrite a previously written, still root-owned state file,
resulting in build job failures. To resolve this we should manually
delete caches containing such root-owned files, but that would be a
hassle. Instead, work this around by changing the owner of the whole
contents of the cache directory to the host user ID.

Some of our 'ci/*' scripts repeat the name or full path of the Travis
CI cache directory, and the following patches will add new places
using that path.
Use a variable to refer to the path of the cache directory instead, so
it's hard-coded only in a single place.
Pay extra attention to the 32 bit Linux build: it runs in a Docker
container, so pass the path of the cache directory from the host to
the container in an environment variable. Note that an environment
variable passed this way is exported inside the container, therefore
its value is directly available in the 'su' snippet even though that
snippet is single quoted. Furthermore, use the variable in the
container only if it's been assigned a non-empty value, to prevent
errors when someone is running or debugging the Docker build locally,
because in that case the variable won't be set as there won't be any
Travis CI cache.

The script 'ci/run-linux32-build.sh' running inside the Docker
container of the 32 bit Linux build job uses an && chain to break the
build if one of the commands fails. This is problematic for two
reasons:
- The && chain is broken, because there is this in the middle:
test -z $HOST_UID || (CI_USER="ci" && useradd -u $HOST_UID $CI_USER) &&
Luckily it is broken in a way that it didn't lead to false
successes. If installing dependencies fails, then the rest of the
first && chain is skipped and execution resumes after the ||
operator. At that point $HOST_UID is still unset, causing
'useradd' to error out with "invalid user ID 'ci'", which in turn
causes the second && chain to abort the script and thus break the
build.
- All other 'ci/*' scripts use 'set -e' to break the build if one of
the commands fails. This inconsistency among these scripts is
asking for trouble: I forgot about the && chain more than once
while working on this patch series.
Enable 'set -e' for the whole script and for the commands executed
under 'su' as well.
While touching every line in the 'su' command block anyway, change
their indentation to use a tab instead of spaces.

Split index mode only has a few dedicated tests, but as the index is
involved in nearly every git operation, this doesn't quite cover all the
ways repositories with split index can break. To use split index mode
throughout the test suite a GIT_TEST_SPLIT_INDEX environment variable
can be set, which makes git split the index at random and thus
excercises the functionality much more thoroughly.
As this is not turned on by default, it is not executed nearly as often
as the test suite is run, so occationally breakages slip through. Try
to counteract that by running the test suite with GIT_TEST_SPLIT_INDEX
mode turned on on travis.
To avoid using too many cycles on travis only run split index mode in
the linux-gcc target only. The Linux build was chosen over the Mac OS
builds because it tends to be much faster to complete.
The linux gcc build was chosen over the linux clang build because the
linux clang build is the fastest build, so it can serve as an early
indicator if something is broken and we want to avoid spending the extra
cycles of running the test suite twice for that.

Ever since we started building and testing Git on Travis CI (522354d70
(Add Travis CI support, 2015-11-27)), we build Git in the
'before_script' phase and run the test suite in the 'script' phase
(except in the later introduced 32 bit Linux and Windows build jobs,
where we build in the 'script' phase').
Contrarily, the Travis CI practice is to build and test in the
'script' phase; indeed Travis CI's default build command for the
'script' phase of C/C++ projects is:
./configure && make && make test
The reason why Travis CI does it this way and why it's a better
approach than ours lies in how unsuccessful build jobs are
categorized. After something went wrong in a build job, its state can
be:
- 'failed', if a command in the 'script' phase returned an error.
This is indicated by a red 'X' on the Travis CI web interface.
- 'errored', if a command in the 'before_install', 'install', or
'before_script' phase returned an error, or the build job exceeded
the time limit. This is shown as a red '!' on the web interface.
This makes it easier, both for humans looking at the Travis CI web
interface and for automated tools querying the Travis CI API, to
decide when an unsuccessful build is our responsibility requiring
human attention, i.e. when a build job 'failed' because of a compiler
error or a test failure, and when it's caused by something beyond our
control and might be fixed by restarting the build job, e.g. when a
build job 'errored' because a dependency couldn't be installed due to
a temporary network error or because the OSX build job exceeded its
time limit.
The drawback of building Git in the 'before_script' phase is that one
has to check the trace log of all 'errored' build jobs, too, to see
what caused the error, as it might have been caused by a compiler
error. This requires additional clicks and page loads on the web
interface and additional complexity and API requests in automated
tools.
Therefore, move building Git from the 'before_script' phase to the
'script' phase, updating the script's name accordingly as well.
'ci/run-builds.sh' now becomes basically empty, remove it. Several of
our build job configurations override our default 'before_script' to
do nothing; with this change our default 'before_script' won't do
anything, either, so remove those overriding directives as well.

untracked. The next commit is about to make sure that there are no
untracked files present after the build, and the downloaded

Travis CI dutifully builds and tests each new branch tip, even if its
tree has previously been successfully built and tested. This happens
often enough in contributors' workflows, when a work-in-progress
branch is rebased changing e.g. only commit messages or the order or
number of commits while leaving the resulting code intact, and is then
pushed to a Travis CI-enabled GitHub fork.
This is wasting Travis CI's resources and is sometimes scary-annoying
when the new tip commit with a tree identical to the previous,
successfully tested one is suddenly reported in red, because one of
the OSX build jobs happened to exceed the time limit yet again.
So extend our Travis CI build scripts to skip building commits whose
trees have previously been successfully built and tested. Use the
Travis CI cache feature to keep a record of the object names of trees
that tested successfully, in a plain and simple flat text file, one
line per tree object name. Append the current tree's object name at
the end of every successful build job to this file, along with a bit
of additional info about the build job (commit object name, Travis CI
job number and id). Limit the size of this file to 1000 records, to
prevent it from growing too large for git/git's forever living
integration branches. Check, using a simple grep invocation, in each
build job whether the current commit's tree is already in there, and
skip the build if it is. Include a message in the skipped build job's
trace log, containing the URL to the build job successfully testing
that tree for the first time and instructions on how to force a
re-build. Catch the case when a build job, which successfully built
and tested a particular tree for the first time, is restarted and omit
the URL of the previous build job's trace log, as in this case it's
the same build job and the trace log has just been overwritten.
Note: this won't kick in if two identical trees are on two different
branches, because Travis CI caches are not shared between build jobs
of different branches.

It seems that Travis CI creates the cache directory for us anyway,
even when a previous cache doesn't exist for the current build job.
Alas, this behavior is not explicitly documented, therefore we don't
rely on it and create the cache directory ourselves in those build
jobs that read/write cached data (currently only the prove state).
In the following commit we'll start to cache additional data in every
build job, and will access the cache much earlier in the build
process.
Therefore move creating the cache directory to 'ci/lib-travisci.sh' to
make sure that it exists at the very beginning of every build job.

- 'ci/run-linux32-build.sh' is executed in a Docker container and
therefore doesn't source 'ci/lib-travisci.sh', which would enable
tracing executed commands. Enable 'set -x' in this script, too.
- 'ci/print-test-failures.sh' iterates over all the files containing
the exit codes of all the executed test scripts. Since there are
over 800 such files, the loop produces way too much noise with
tracing executed commands enabled, so disable 'set -x' for this
script.
- 'ci/run-windows-build.sh' busily waits in a loop for the result of
the Windows build, producing too much noise with tracing executed
commands enabled as well. Disable 'set -x' for the duration of

Commit 657343a60 (travis-ci: move Travis CI code into dedicated
scripts, 2017-09-10) converted '.travis.yml's default 'before_install'
scriptlet to the 'ci/install-dependencies.sh' script, and while doing
so moved setting GIT_TEST_HTTPD=YesPlease for the 64-bit GCC and Clang
Linux build jobs to that script. This is wrong for two reasons:
- The purpose of that script is, as its name suggests, to install
dependencies, not to set any environment variables influencing
which tests should be run (though, arguably, this was already an
issue with the original 'before_install' scriptlet).
- Setting the variable has no effect anymore, because that script is
run in a separate shell process, and the variable won't be visible
in any of the other scripts, notably in 'ci/run-tests.sh'
responsible for, well, running the tests.
Luckily, this didn't have a negative effect on our Travis CI build
jobs, because GIT_TEST_HTTPD is a tri-state variable defaulting to
"auto" and a functioning web server was installed in those Linux build
jobs, so the httpd tests were run anyway.
Apparently the httpd tests run just fine without GIT_TEST_HTTPD being
set, therefore we could simply remove this environment variable.
However, if a bug were to creep in to change the Travis CI build
environment to run the tests as root or to not install Apache, then
the httpd tests would be skipped and the build job would still
succeed. We would only notice if someone actually were to look
through the build job's trace log; but who would look at the trace log
of a successful build job?!
Since httpd tests are important, we do want to run them and we want to
be loudly reminded if they can't be run. Therefore, move setting
GIT_TEST_HTTPD=YesPlease for the 64-bit GCC and Clang Linux build jobs
to 'ci/lib-travisci.sh' to ensure that the build job fails when the
httpd tests can't be run. (We could set it in 'ci/run-tests.sh' just
as well, but it's better to keep all environment variables in one
place in 'ci/lib-travisci.sh'.)

Our '.travis.yml's 'env.global' section sets a bunch of environment
variables for all build jobs, though none of them actually affects all
build jobs. It's convenient for us, and in most cases it works just
fine, because irrelevant environment variables are simply ignored.
However, $GIT_SKIP_TESTS is an exception: it tells the test harness to
skip the two test scripts that are prone to occasional failures on
OSX, but as it's set for all build jobs those tests are not run in any
of the build jobs that are capable to run them reliably, either.
Therefore $GIT_SKIP_TESTS should only be set in the OSX build jobs,
but those build jobs are included in the build matrix implicitly (i.e.
by combining the matrix keys 'os' and 'compiler'), and there is no way
to set an environment variable only for a subset of those implicit
build jobs. (Unless we were to add new scriptlets to '.travis.yml',
which is exactly the opposite direction that we took with commit
657343a60 (travis-ci: move Travis CI code into dedicated scripts,
2017-09-10)).
So move setting $GIT_SKIP_TESTS to 'ci/lib-travisci.sh', where it can
trivially be set only for the OSX build jobs.
Furthermore, move setting all other environment variables from
'.travis.yml' to 'ci/lib-travisci.sh', too, because a couple of
environment variables are already set there, and this way all
environment variables will be set in the same place. All the logic
controlling our builds is already in the 'ci/*' scripts anyway, so
there is really no good reason to keep the environment variables
separately.

A couple of 'ci/*' scripts are shared between different build jobs:
'ci/lib-travisci.sh', being a common library, is sourced from almost
every script, while 'ci/install-dependencies.sh', 'ci/run-build.sh'
and 'ci/run-tests.sh' are shared between the "regular" GCC and Clang
Linux and OSX build jobs, and the latter two scripts are used in the
GETTEXT_POISON Linux build job as well.
Our builds could benefit from these shared scripts being able to
easily tell which build job they are taking part in. Now, it's
already quite easy to tell apart Linux vs OSX and GCC vs Clang build
jobs, but it gets trickier with all the additional Linux-based build
jobs included explicitly in the build matrix.
Unfortunately, Travis CI doesn't provide much help in this regard.
The closest we've got is the $TRAVIS_JOB_NUMBER variable, the value of
which is two dot-separated integers, where the second integer
indicates a particular build job. While it would be possible to use
that second number to identify the build job in our shared scripts, it
doesn't seem like a good idea to rely on that:
- Though the build job numbering sequence seems to be stable so far,
Travis CI's documentation doesn't explicitly states that it is
indeed stable and will remain so in the future. And even if it
were stable,
- if we were to remove or insert a build job in the middle, then the
job numbers of all subsequent build jobs would change accordingly.
So roll our own means of simple build job identification and introduce
the $jobname environment variable in our builds, setting it in the
environments of the explicitly included jobs in '.travis.yml', while
constructing one in 'ci/lib-travisci.sh' as the combination of the OS
and compiler name for the GCC and Clang Linux and OSX build jobs. Use
$jobname instead of $TRAVIS_OS_NAME in scripts taking different
actions based on the OS and build job (when installing P4 and Git LFS
dependencies and including them in $PATH). The following two patches

The reason is that P4 and Git LFS binaries are not installed to a
directory in the default $PATH, but their directories are prepended to
$PATH. This worked just fine before said commit, because $PATH was
set in a scriptlet embedded in our '.travis.yml', thus its new value
was visible during the rest of the build job. However, after these
embedded scriptlets were moved into dedicated scripts executed in
separate shell processes, any variable set in one of those scripts is
only visible in that single script but not in any of the others. In
this case, 'ci/install-dependencies.sh' downloads P4 and Git LFS and
modifies $PATH, but to no effect, because 'ci/run-tests.sh' only sees
Travis CI's default $PATH.
Move adjusting $PATH to 'ci/lib-travisci.sh', which is sourced in all
other 'ci/' scripts, so all those scripts will see the updated $PATH

Most Git developers work on Linux and they have no way to know if their
changes would break the Git for Windows build. Let's fix that by adding
a job to TravisCI that builds and tests Git on Windows. Unfortunately,
TravisCI does not support Windows.
Therefore, we did the following:
* Johannes Schindelin set up a Visual Studio Team Services build
sponsored by Microsoft and made it accessible via an Azure Function
that speaks a super-simple API. We made TravisCI use this API to
trigger a build, wait until its completion, and print the build and
test results.
* A Windows build and test run takes up to 3h and TravisCI has a timeout
after 50min for Open Source projects. Since the TravisCI job does not
use heavy CPU/memory/etc. resources, the friendly TravisCI folks
extended the job timeout for git/git to 3h.
Things, that would need to be done:
* Someone with write access to https://travis-ci.org/git/git would need
to add the secret token as "GFW_CI_TOKEN" variable in the TravisCI
repository setting [1]. Afterwards the build should just work.
Things, that might need to be done:
* The Windows box can only process a single build at a time. A second
Windows build would need to wait until the first finishes. This
waiting time and the build time after the wait could exceed the 3h
threshold. If this is a problem, then it is likely to happen every day
as usually multiple branches are pushed at the same time (pu/next/
master/maint). I cannot test this as my TravisCI account has the 50min
timeout. One solution could be to limit the number of concurrent
TravisCI jobs [2].

When Git v2.9.1 was released, it had a bug that showed only on Windows
and on 32-bit systems: our assumption that `unsigned long` can hold
64-bit values turned out to be wrong.
This could have been caught earlier if we had a Continuous Testing
set up that includes a build and test run on 32-bit Linux.
Let's do this (and take care of the Windows build later). This patch
asks Travis CI to install a Docker image with 32-bit libraries and then
goes on to build and test Git using this 32-bit setup.
