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.

Above the declaration of git_work_tree_cfg, we have:
/* This is set by setup_git_dir_gently() and/or git_default_config() */
char *git_work_tree_cfg;
It can be verified that there is no function called
'setup_git_dir_gently' by running grep on the codebase:
$ grep -R setup_git_dir_gently .
./environment.c:/* This is set by setup_git_dir_gently() and/or git_default_config() */
The comment, introduced in e90fdc39b6 (Clean up work-tree handling), is
the only occurrence of the name 'setup_git_dir_gently'.
It probably meant 'setup_git_directory_gently' as that is a name of a
real function in setup.c. Correct it.

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.

With the preceding commit, `OPT_INTEGER()` has learned to support unit
factors. Consequently, the major differencen between `OPT_INTEGER()` and
`OPT_MAGNITUDE()` isn't the support of unit factors anymore, as both of
them do support them now. Instead, the difference is that one handles
signed and the other handles unsigned integers.
Adapt the name of `OPT_MAGNITUDE()` accordingly by renaming it to
`OPT_UNSIGNED()`.

There are two main differences between `OPT_INTEGER()` and
`OPT_MAGNITUDE()`:
- The former parses signed integers whereas the latter parses unsigned
integers.
- The latter parses unit factors like 'k', 'm' or 'g'.
While the first difference makes obvious sense, there isn't really a
good reason why signed integers shouldn't support unit factors, too.
This inconsistency will also become a bit of a problem with subsequent
commits, where we will fix a couple of callsites that pass an unsigned
integer to `OPT_INTEGER()`. There are three options:
- We could adapt those users to instead pass a signed integer, but
this would needlessly extend the range of accepted integer values.
- We could convert them to use `OPT_MAGNITUDE()`, as it only accepts
unsigned integers. But now we have the inconsistency that we also
start to accept unit factors.
- We could introduce `OPT_UNSIGNED()` as equivalent to `OPT_INTEGER()`
so that it knows to only accept unsigned integers without unit
suffix.
Introducing a whole new option type feels a bit excessive. There also
isn't really a good reason why `OPT_INTEGER()` cannot be extended to
also accept unit factors: all valid values passed to such options cannot
have a unit factors right now, so there wouldn't be any ambiguity.
Refactor `OPT_INTEGER()` to use `git_parse_int()`, which knows to
interpret unit factors. This removes the inconsistency between the
signed and unsigned options so that we can easily fix up callsites that
pass the wrong integer type right now.

While we expose macros for most of our different option types understood
by the "parse-options" subsystem, not every combination of fields that
has one as that would otherwise quickly lead to an explosion of macros.
Instead, we just initialize structures manually for those variants of
fields that don't have a macro.
Callsites that open-code these structure initialization don't use
designated initializers though and instead just provide values for each
of the fields that they want to initialize. This has three significant
downsides:
- Callsites need to specify all values up to the last field that they
care about. This often includes fields that should simply be left at
their default zero-initialized state, which adds distraction.
- Any reader not deeply familiar with the layout of the structure
has a hard time figuring out what the respective initializers mean.
- Reordering or introducing new fields in the middle of the structure
is impossible without adapting all callsites.
Convert all sites to instead use designated initializers, which we have
started using in our codebase quite a while ago. This allows us to skip
any default-initialized fields, gives the reader context by specifying
the field names and allows us to reorder or introduce new fields where
we want to.

We accept a maximum value in `git_parse_signed()` that restricts the
range of accepted integers. As the intent is to pass `INT*_MAX` values
here, this maximum doesn't only act as the upper bound, but also as the
implicit lower bound of the accepted range.
This lower bound is calculated by negating the maximum. But given that
the maximum value of a signed integer with N bits is `2^(N-1)-1` whereas
the minimum value is `-2^(N-1)` we have an off-by-one error in the lower
bound.
Fix this off-by-one error by using `-max - 1` as lower bound instead.

Although sysinfo() is a 'Linux only' function, cygwin provides an
implementation which appears to be functional. The assumption that
this function is Linux only is reflected in the way the HAVE_SYSINFO
build variable is handled by the Makefile and config.mak.uname.
Rework the setting of HAVE_SYSINFO in the Linux section of the system
specific config file, along with the corresponding setting of the
BASIC_CFLAGS in the Makefile. Add the setting of HAVE_SYSINFO to the
cygwin section of 'config.mak.uname'. While here, add a test for the
sysinfo() function to the autoconf build system.

The man page for sysinfo(2) on Linux states that (from v2.3.48) the
sizes of the memory and swap fields, of the returned structure, are
given as multiples of 'mem_unit' bytes. In earlier versions (prior to
v2.3.23 on i386 in particular), the 'mem_unit' field was not part of
the structure, and all sizes were measured in bytes. The man page does
not discuss the motivation for this change, but it is possible that the
change was intended for the, relatively rare, 32-bit platform with more
than 4GB of memory.
The total_ram() function makes the assumption that the 'totalram' field
of the 'struct sysinfo' is measured in bytes, or alternatively that the
'mem_unit' field is always equal to one. Having writen a program to call
the sysinfo() function and print the structure fields, it seems that, on
Linux x84_64 and i686 anyway, the 'mem_unit' field is indeed set to one
(note that the 32-bit system had only 2GB ram). However, cygwin also has
an sysinfo() implementation, which gives the following values:
$ ./sysinfo
uptime: 21381
loads: 0, 0, 0
total ram: 2074637
free ram: 843237
shared ram: 0
buffer ram: 0
total swap: 327680
free swap: 306932
procs: 15
total high: 0
free high: 0
mem_unit: 4096
total ram: 8497713152
$
[This laptop has 8GB ram, so a little bit seems to be missing. ;) ]
Modify the total_ram() function to allow for the possibility that the
memory size is not specified in bytes (ie 'mem_unit' is greater than
one).

Commit 92f63d2b05 ("Cygwin 1.7 needs compat/regex", 2013-07-19) set
the NO_REGEX build variable because the platform regex library failed
some of the tests (t4018 and t4034), which passed just fine with the
compat library.
After some time (maybe a year or two), the platform library had been
updated (with an import from FreeBSD, I believe) and now passed the full
test-suite. This would be about the time of the v1.7 -> v2.0 transition
in 2015. I had a patch ready to send, but just didn't get around to
submitting it to the list. At some point in the interim, the official
cygwin git package used the autoconf build system, which sets the
NO_REGEX variable to use the platform regex library functions. The new
meson build system does likewise.
The cygwin platform regex library, in addition to now passing the tests
which formerly failed, now passes an 'test_expect_failure' test in the
t7815-grep-binary test file. In particular, test #12 'git grep .fi a'
which determines that the regex pattern '.' matches a NUL character.
The commit f96e56733a ("grep: use REG_STARTEND for all matching if
available", 2010-05-22) added the test in question, but it does not
give any indication as to why the test was framed as an expected fail,
rather than a 'positive' test that the 'git grep' command fails to
match a NUL. Note that the previous test #11 was also originally
marked in that commit as a 'test_expect_failure', but was flipped to
an 'success' test in commit 7e36de5859 ("t/t7008-grep-binary.sh: un-TODO
a test that needs REG_STARTEND", 2010-08-17).
In order to produce the same NO_REGEX configuration from autoconf, meson
and make, modify config.mak.uname to only set NO_REGEX for cygwin v1.7.
In addition, skip test t7815.12 on cygwin, by adding the !CYGWIN pre-
requisite to the test header, which (among other things) removes an
'...; please update test(s)' comment.

Commit 817151e61a ("Rename safe_strncpy() to strlcpy().", 2006-06-24)
added the NO_STRLCPY make variable to allow the conditional use of
the gitstrlcpy() compat function on those platforms which didn't
provide the 'standard' strlcpy() function.
Recently, in the summer of 2023, the strlcpy() and strlcat() functions
were added to the glibc library (v2.38), so some of the more up-to-date
Linux distributions no longer need to set NO_STRLCPY. For example, both
Ubuntu 24.04 LTS and RHEL 10 beta have glibc v2.39. However, several
distributions, which are still within their support window, have an
earlier version and must still use the 'compat' version of strlcpy().
If the meson or autoconf build systems are used on newer platforms, then
they will be configured to to use strlcpy() from glibc, whereas the make
build will always choose the 'compat' function instead. Add a note to
the config.mak.uname file, in the Linux section, to prompt make users to
override NO_STRLCPY in the config.mak file, if appropriate.

Commit d19e3a5b21 ("Makefile: add NEEDS_LIBRT to optionally link with

disassociate the HAVE_CLOCK_GETTIME variable with the unconditional
linking of the librt library. At one time, the clock_gettime() function
was not available as part of the libc library and (on some unix systems)
required linking with librt.
Commit 52fcec75ce ("config.mak.uname: define NEEDS_LIBRT under Linux, for

the config.mak.uname file, since Debian 7 (wheezy) was one of the few
remaining distributions, with glibc 2.13, that required linking with
librt for clock_gettime(). Note that from glibc version 2.17, this is no
longer necessary.
Note that Debian 7.0 was released on May 4th, 2013 and benefited from
long term support until May 2018 when it went end-of-life. Since that
time, Linux distributions use a more up-to-date library, for example:
Distribution version end of support
Debian 8 2.19 30th June 2020
RHEL 8 2.28 31st May 2024 *
Ubuntu 16.04 2.23 30th Apr 2021
* paid 'Maintenance support' ends 31st May 2029

The build variable DEFAULT_HELP_FORMAT has an appropriate default
('man') set in the code, so there is no need to pass the -Define on
the compiler command-line, unless the build requires a non-standard
value.
In addition, on windows the make build overrides the default help
format to 'html', rather than 'man', in the 'config.mak.uname' file.
In order to suppress the -Define on the C compiler command-line, only
add the -Define to the 'libgit_c_args' variable when the requested
value is not the standard 'man'. In order to override the default value
on windows, add a 'platform' value to the 'default_help_format' combo
option and set it as the default choice. When this option is set to
'platform', use the 'host_machine.system()' method call to determine the
appropriate default value for the host system.

Also, the 'git-var' documentation contains some conditional text which
documents the chosen compiled in value, which would not read well for

build does not provide any sparse targets, so there is no need to use
the CURL_DISABLE_TYPECHECK preprocessor flag with the c compiler.
In order to re-enable the curl 'type checking' in the meson build, remove
the assignment of -DCURL_DISABLE_TYPECHECK to libgit_c_args.
