The ci/install-dependencies.sh script used in a very early phase of
our CI jobs downloads Perforce, Git-LFS, and JGit, used for running
the test scripts. The test framework is prepared to properly skip
the tests that depend on these external software, but the CI script
is unnecessarily strict (due to its use of "set -e" in ci/lib.sh)
and fails the entire CI run before even starting to test the rest of
the system.
Notice a failure to download to any of these external software, but
keep going. We need to be careful about cleaning after a failed
wget, as a later part of the script that does:
if type jgit >/dev/null 2>&1
then
echo "$(tput setaf 6)JGit Version$(tput sgr0)"
jgit version
else
echo >&2 "WARNING: JGit wasn't installed, see above for clues why"
fi
will (surprise!) succeed running "type jgit", and then fail with
"jgit version", taking the whole thing down due to "set -e".

When using the launchctl scheduler, the weekly job runs daily, and the
daily job runs on the first six days of each month. This appears to be
due to specifying "Day" in the calendar intervals, which according to
launchd.plist(5) is for specifying days of the month rather than days of
the week. The behaviour of running a job on the 0th day is undocumented,
but in my testing appears to be the same as not specifying "Day" in the
calendar interval, in which case the job will run daily.
Use "Weekday" in the calendar intervals, which is the correct way to
schedule jobs to run on specific days of the week.

The 'hdr-check' target in Meson and makefile is used to check if headers
can be compiled individually. The naming however isn't readable as 'hdr'
is not a common shortforme for 'header', neither is it an abbreviation.
Let's introduce 'check-headers' as an alternative target for 'hdr-check'
and add a `TODO` to deprecate the latter after 2 releases. Since this
is an internal tool, we can use a shorter deprecation cycle.

The Makefile supports a target called 'hdr-check', which checks if
individual header files can be independently compiled. Let's port this
functionality to Meson, our new build system too. The implementation
resembles that of the Makefile and provides the same check.
Since meson builds are out-of-tree, header dependencies are not
automatically met. So unlike the Makefile version, we also need to add
the required dependencies.
Also add the 'xdiff/' dir to the list of 'third_party_sources' as those
headers must be skipped from the checks too. This also skips the folder
from the 'coccinelle' checks, this is okay, since this code is an
external dependency.

The Meson build for coccinelle static analysis lists all headers to
analyse. Due to the way Meson exports variables between subdirs, this
variable is also available in the root Meson build.
An upcoming commit, will add a new check complimenting 'hdr-check' in
the Makefile. This would require the list of headers. So move the
'coccinelle_headers' to the root Meson build and rename it to 'headers',
remove the root path being appended to each header and retain that in
the coccinelle Meson build since it is specific to the coccinelle build.
Also move the 'third_party_sources' variable to the root Meson build
since it is also a dependency for the 'headers' variable. This also
makes it easier to understand as the variable is now propagated from the
top level to the bottom.
While 'headers_to_check' is only computed when we have a repository and
the 'git' executable is present, the variable itself is exposed as an
empty array. This allows dependencies in upcoming commits to simply
check for length of the array and not worry about dependencies required
to actually populate the array.

top level 'meson.build'.
Rename them to be more specific, this ensures that they aren't

The GitHub's CI workflow uses 'actions/checkout@v4' to checkout the
repository. This action defaults to using the GitHub REST API to obtain
the repository if the `git` executable isn't available.
The step to build Git in the GitHub workflow can be summarized as:
...
- uses: actions/checkout@v4 #1
- run: ci/install-dependencies.sh #2
...
- run: sudo --preserve-env --set-home --user=builder ci/run-build-and-tests.sh #3
...
Step #1, clones the repository, since the `git` executable isn't present
at this step, it uses GitHub's REST API to obtain a tar of the
repository.
Step #2, installs all dependencies, which includes the `git` executable.
Step #3, sets up the build, which includes setting up meson in the meson
job. At this point the `git` executable is present.
This means while the `git` executable is present, the repository doesn't
contain the '.git' folder. To keep both the CI's (GitLab and GitHub)
behavior consistent and to ensure that the build is performed on a
real-world scenario, install `git` before the repository is checked out.
This ensures that 'actions/checkout@v4' will clone the repository
instead of using a tarball. We also update the package cache while
installing `git`, this is because some distros will fail to locate the
package without updating the cache.

This perf script creates a midx by running "git multi-pack-index write"
with the "--stdin-packs" option. We feed that stdin by running "find" on
.git/objects/pack, using sed to strip off everything but the basename.
But that sed invocation also does something peculiar: it adds a "+" to
the start of each pack name. This causes the multi-pack-index command to
barf. The modified name does not match any pack it knows about, so it
ends up with an empty list of packs to put in the midx. And thus nothing
matches the --preferred-pack option we pass, which causes it die().
The fix is to remove the extra "+" (which also lets us simplify the sed
invocation a bit, as it is now just stripping the leading directories).
But that leaves the mystery of why it was ever there in the first place.
The answer is that an earlier iteration of the patch series had a
concept of "disjoint" packs in the midx. And one of its patches here:
https://lore.kernel.org/git/c52d7e7b27a9add4f58b8334db4fe4498af1c90f.1701198172.git.me@ttaylorr.com/
taught read_packs_from_stdin() to treat a leading "+" as marking a
disjoint pack. But in the second version of the series, which was
ultimately merged, that disjoint concept went away, and the code to
parse "+" did likewise. The regular regression tests were adjusted to
match, but this case in t/perf was forgotten.

The shell completion scripts in "contrib/completion" are being tested,
but none of our build systems support installing them. This is somewhat
confusing for Meson, where users can explicitly enable building these
scripts via `-Dcontrib=completion`. This option only controlls whether
the completions are built and tested against, where "building" is a bit
of an euphemism for "copying them into the build directory".
Teach both our Makefile and Meson to install our Bash completion script.
For now, this is the only completion script that we're installing given
that Bash completions "just work" with a canonical well-known location
nowadays. Other completion scripts, like for example the one for zsh,
don't have a well-known location and/or require extra steps by the user
to make them available. As such, we skip installing these scripts for

Our tests for git-p4(1) depend on the p4d(1) and p4(1) executables to
exist. As we require specific versions of those binaries which typically

"ci/install-dependencies.sh".
This script will put the binaries into "$CUSTOM_PATH", which gets
defined by "ci/lib.sh" -- if not explicitly overridden, its value will
be set to "$HOME/path". This causes issues though when running our tests
as unprivileged user, as we do both in GitLab CI and GitHub Actions,
because "$HOME" will be different when installing dependencies and when
running the tests. Consequently, the downloaded binaries will not be
found unless "$CUSTOM_PATH" is overridden to a common location.

A common way to run Git's performance benchmarks on repositories other
than Git's own repository (which is not exactly large when compared to
actually large repositories) is to run them like this:
GIT_PERF_LARGE_REPO=/path/to/my/large/repo \
./p1234-*.sh -ivx
Contrary to developers' common expectations, this failed to work when
Git was built with a different `GIT_PERF_LARGE_REPO` value specified at
build time: That build-time option would have been written to the
`GIT-BUILD-OPTIONS` file, which in turn would have been sourced by
`test-lib.sh`, which in turn would have been sourced by `perf-lib.sh`,
which in turn would have been sourced by the perf test script,
_overriding_ the environment variable specified in the way illustrated
above.
Since perf tests are not run as part of the build, this most likely
unintended behavior was not caught and certainly not fixed, as the
`GIT_PERF_*` values would have been empty at build-time.
However, in 4638e8806e3a (Makefile: use common template for
GIT-BUILD-OPTIONS, 2024-12-06), a subtle change of behavior was
introduced: Whereas before, a couple of build-time options (the
`GIT_PERF_*` ones included) were written to `GIT-BUILD-OPTIONS` only
when their values were non-empty. With this commit, they are also
written when they are empty.
The consequence is that above-mentioned way to run the perf tests will
not only fail to pick up the desired `GIT_PERF_*` settings when they
were specified differently while building Git, instead the desired
settings will be only respected when specified _while building_ Git.
Let's work around the original issue, i.e. let `GIT_PERF_*` environment
variables override what is recorded in `GIT-BUILD-OPTIONS`.
Note that this is just the tip of the iceberg, there are a couple of
`GIT_TEST_*` options that may want a similar fix in `test-lib.sh`. Due
to time constraints on my side, this here patch focuses exclusively on
the `GIT_PERF_*` settings.

Commit 05cd988dce ("wrapper: add a helper to generate numbers from a
CSPRNG", 2022-01-17) added a csprng_bytes() function which used one
of several interfaces to provide a source of cryptographically secure
pseudorandom numbers. The CSPRNG_METHOD make variable was provided to
determine the choice of available 'backends' for the source of random
bytes.
Commit 05cd988dce did not set CSPRNG_METHOD in the Linux section of
the config.mak.uname file, so it defaults to using '/dev/urandom' as
the source of random bytes. The 'backend' values which could be used
on Linux are 'arc4random', 'getrandom' or 'getentropy' ('openssl' is
an option, but seems to be discouraged).
The arc4random routines (arc4random_buf() is the one actually used) were
added to glibc in version 2.36, while both getrandom() and getentropy()
were included in 2.25. So, some of the more up-to-date distributions of
Linux (eg Debian 12, Ubuntu 24.04) would be able to use the 'arc4random'
setting. All currently supported distributions have glibc 2.25 or later
(RHEL 8 has v2.28) and, therefore, have support for the 'getrandom' and
'getentropy' settings.
The arc4random routines on the *BSDs (along with cygwin) implement the
ChaCha20 stream cipher algorithm (see RFC8439) in userspace, rather than
as a system call, and are thus somewhat faster (having avoided a context
switch to the kernel). In contrast, on Linux all three functions are
simple wrappers around the same kernel CSPRNG syscall.
If the meson build system is used on a newer platform, then they will be
configured to use 'arc4random', whereas the make build will currently
default to using '/dev/urandom' on Linux. Since there is no advantage,
in terms of performance, to the 'arc4random' setting, the 'getrandom'
setting should be preferred from an availability perspective. (Also, the
current uses of csprng_bytes() are not in any hot path).
In order to set an appropriate default, set the CSPRNG_METHOD build
variable to 'getrandom' in the Linux section of the 'config.mak.uname'
file.

It was reported that "t5620-backfill.sh" fails on s390x and sparc64 in a
test that exercises the "--min-batch-size" command line option. The
symptom was that the option didn't seem to have an effect: we didn't
fetch objects with a batch size of 20, but instead fetched all objects
at once.
As it turns out, the root cause is that `--min-batch-size` uses
`OPT_INTEGER()` to parse the command line option. While this macro
expects the caller to pass a pointer to an integer, we instead pass a
pointer to a `size_t`. This coincidentally works on most platforms, but
it breaks apart on the mentioned platforms because they are big endian.
This issue isn't specific to git-backfill(1): there are a couple of
other places where we have the same type confusion going on. This
indicates that the issue really is the interface that the parse-options
subsystem provides -- it is simply too easy to get this wrong as there
isn't any kind of compiler warning, and things just work on the most
common systems.
Address the systemic issue by introducing two new build asserts
`BARF_UNLESS_SIGNED()` and `BARF_UNLESS_UNSIGNED()`. As the names
already hint at, those macros will cause a compiler error when passed a
value that is not signed or unsigned, respectively.
Adapt `OPT_INTEGER()`, `OPT_UNSIGNED()` as well as `OPT_MAGNITUDE()` to
use those asserts. This uncovers a small set of sites where we indeed
have the same bug as in git-backfill(1). Adapt all of them to use the
correct option.

The `OPTION_INTEGER` option type accepts a signed integer. The type of
the underlying integer is a simple `int`, which restricts the range of
values accepted by such options. But there is a catch: because the
caller provides a pointer to the value via the `.value` field, which is
a simple void pointer. This has two consequences:
- There is no check whether the passed value is sufficiently long to
store the entire range of `int`. This can lead to integer wraparound
in the best case and out-of-bounds writes in the worst case.
- Even when a caller knows that they want to store a value larger than
`INT_MAX` they don't have a way to do so.
In practice this doesn't tend to be a huge issue because users typically
don't end up passing huge values to most commands. But the parsing logic
is demonstrably broken, and it is too easy to get the calling convention
wrong.
Improve the situation by introducing a new `precision` field into the
structure. This field gets assigned automatically by `OPT_INTEGER_F()`
and tracks the size of the passed value. Like this it becomes possible
for the caller to pass arbitrarily-sized integers and the underlying
logic knows to handle it correctly by doing range checks. Furthermore,
convert the code to use `strtoimax()` intstead of `strtol()` so that we
can also parse values larger than `LONG_MAX`.
Note that we do not yet assert signedness of the passed variable, which
is another source of bugs. This will be handled in a subsequent commit.
