Updates to meson-based build procedure.
* rj/build-tweaks-part2:
configure.ac: upgrade to a compilation check for sysinfo
meson.build: correct setting of GIT_EXEC_PATH
meson: correct path to system config/attribute files
meson: correct install location of YAML.pm
meson.build: quote the GITWEBDIR build configuration
For the non-'runtime prefix' case, the meson build sets the GIT_EXEC_PATH
build variable to an absolute path equivalent to <prefix>/libexec/git-core.
In comparison, the default make build sets it to a relative path equivalent
to 'libexec/git-core'. Indeed, the make build requires the use of some
means outside of the Makefile (eg. config.mak[.*] or the command-line)
to set GIT_EXEC_PATH to anything other than 'libexec/git-core'.
For example, the make invocation:
$ make gitexecdir=/some/other/bin all install
will build git with GIT_EXEC_PATH set to '/some/other/bin' and install
the 'library' executables to that location. However, without setting the
'gitexecdir' make variable, irrespective of the 'runtime prefix' setting,
the GIT_EXEC_PATH is always set to 'libexec/git-core'.
The meson built-in 'libexecdir' option can be used to provide a similar
configurability. The default value for the option is 'libexec'. Attempting
to set the option to '' on the command-line, will reset it to the '.'
string, presumably to ensure a relative path value.
This commit allows the meson build, similar to the above, to configure the
project like:
$ meson setup --buildtype=debugoptimized -Dprefix=$HOME -Dpcre2=disabled \
-Dlibexecdir=/some/other/bin build
so that the GIT_EXEC_PATH is set to '/some/other/bin'. Absent the
-Dlibexecdir argument, the GIT_EXEC_PATH is set to 'libexec/git-core'.
In order to correct the value of GIT_EXEC_PATH, default the value to the
static string value 'libexec/git-core', and only override if the value
of the 'libexecdir' option has a value different to 'libexec' or '.'.
Also, like the Makefile, add a check for an absolute path when the
runtime prefix option is true (and if so, error out).

The path to the system-wide config and attributes files are not being
set correctly in the meson build. Unless explicitly overridden on the
command line during setup, the 'gitconfig' and 'gitattributes' options
are defaulting to absolute paths in the '/etc' system directory. This
is only appropriate if the <prefix> is set specifically to '/usr'.
The directory in which these files are placed is generally referred to
as the 'system configuration directory' or 'sysconfdir' for short. When
the prefix is '/usr' then the sysconfdir is usually set to '/etc', but
any other value for prefix results in the relative directory value 'etc'
instead. (eg if prefix is '/usr/local', then the 'etc' relative value
results in a system configuration directory of '/usr/local/etc'). When
setting the 'sysconfdir' builtin option value, the meson system uses
exactly this algorithm, so we can use get_option('sysconfdir') directly
when setting the (non-overridden) build variables.
In order to allow for overriding from the command line, remove the
default values specified for the 'gitconfig' and 'gitattributes' options
in the 'meson_options.txt' file. This allows the user to specify any
pathname for those options, while being able to test for the unset
(empty) value. An absolute pathname will be used unchanged and a relative
pathname will be appended to '<prefix>/'. These values are then used to
set the 'ETC_GITCONFIG' and 'ETC_GITATTRIBUTES' build variables which are,
in turn, passed to the compiler as '-D' arguments.
When the 'gitconfig' or 'gitattributes' options are not used, then use
the built-in 'sysconfdir' and set the ETC_GITCONFIG build variable to
the string "<sysconfdir>/gitconfig". Similarly, set ETC_ATTRIBUTES to
"<sysconfdir>/gitattributes".

Since 13cb20fc46 ("meson: fix compilation with Visual Studio",
2025-01-22) it has not been possible to list build options via `meson
configure`. This is due to Meson's static analysis of build options
failing to handle constant folding, and thinking we set a totally
invalid default `-std=`.
This is reported upstream but we anyways need to work with existing
versions. It turns out there is a simple solution: turn the entire
default option into a conditional branch, which means Meson sees either
nothing, or everything.
As a result, Git users can once again see pretty-printed options before
building.

Wire up a couple of benchmarking options that we end up writing into our
"GIT-BUILD-OPTIONS" file. These options allow users to control how
exactly benchmarks are executed.
Note that neither `GIT_PERF_MAKE_COMMAND` nor `GIT_PERF_MAKE_OPTS` are
exposed as a build option. Those options are used by "t/perf/run", which
is not used by Meson.

Wire up benchmarks in Meson. The setup is mostly the same as how we wire
up our tests. The only difference is that benchmarks get wired up via
the `benchmark()` option instead of via `test()`, which gives them a bit
of special treatment:
- Benchmarks never run in parallel.
- Benchmarks aren't run by default when tests are executed.
- Meson does not inject the `MALLOC_PERTURB` environment variable.
Using benchmarks is quite simple:
```
$ meson setup build
# Run all benchmarks.
$ meson test -C build --benchmark
# Run a specific benchmark.
$ meson test -C build --benchmark p0000-*
```
Other than that the usual command line arguments accepted when running
tests are also accepted when running benchmarks.
Note that the benchmarking target is somewhat limited because it will
only run benchmarks for the current build. Other use cases, like running
benchmarks against multiple different versions of Git, are not currently
supported. Users should continue to use "t/perf/run" for those use
cases. The script should get extended at one point in time to support
Meson, but this is outside of the scope of this series.

Meson detects the path of the target shell via `find_program("sh")`,
which essentially does a lookup via `PATH`. This may easily lead to a
subtly-broken Git distribution when the build host has its shell in a
location that the target host doesn't know about.
Fix the issue by appending "/bin" to the custom program path, which
causes us to prefer "/bin/sh" over a `PATH`-based lookup. While
"/bin/sh" isn't standardized, this path tends to work alright on Linux
and BSD distributions. Furthermore, "/bin/sh" is also the path we pick
in our Makefile by default, which further demonstrates that this shell
fulfills our needs.
Note that we intentionally append, not prepend, to the custom program
path. This is because the program path can be configured by the user via
the `-Dsane_tool_path=` build option, which should take precedence over
any defaults we pick for the user.

Git needs to know about a couple of executable paths to pick at runtime.
This includes the system shell, but may also optionally include the Perl
and Python interpreters. Meson detects the location of these paths
automatically via `find_program()`, which does a lookup via the `PATH`
environment variable. As such, it may not be immediately obvious to the
developer which paths have been autodetected.
Improve this by exposing runtime executable paths at setup time.

These are added in the Makefile, but not in meson. They probably won't
work well on systems without them.
CMake adds them, but only on non-Windows. Actually, it only performs
compiler checks for hstrerror, but excludes that check on Windows with
the note that it is "incompatible with the Windows build". This seems to
be misleading -- it is not incompatible, it simply doesn't exist. Still,
the compat version should not be used.
I interpret this cmake logic to mean we shouldn't even be checking for
symbol availability on Windows. In addition to making it simple to add
compat definitions, this also probably shaves off a second or two of
configure time on Windows as no compiler check needs to be performed.

On Solaris, sys/sysinfo.h is a completely different file and doesn't
resemble the linux file at all. There is also a sysinfo() function, but
it takes a totally different call signature, which asks for:
- the field you wish to receive
- a `char *buf` to copy the data to
and is very useful IFF you want to know, say, the hardware provider. Or,
get *specific* fields from uname(2).
https://docs.oracle.com/cd/E86824_01/html/E54765/sysinfo-2.html
It is surely possible to do this manually via `sysconf(3)` without the
nice API. I can't find anything more direct. Either way, I'm not very
attached to Solaris, so someone who cares can add it. Either way, it's
wrong to assume that sysinfo.h contains what we are looking for.
Check that sysinfo.h defines the struct we actually utilize in
builtins/gc.c, which will correctly fail on systems that don't have it.

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.

The "cmd-list.perl" script is used to extract the list of commands part
of a specific category and extracts the description of each command from
its respective manpage. The generated output is then included in git(1)
to list all Git commands.
The script is written in Perl. Refactor it to use shell scripting
exclusively so that we can get rid of the mandatory dependency on Perl
to build our documentation.
The converted script is slower compared to its Perl implementation. But
by being careful and not spawning external commands in `format_one ()`
we can mitigate the performance hit to a reasonable level:
Benchmark 1: Perl
Time (mean ± σ): 10.3 ms ± 0.2 ms [User: 7.0 ms, System: 3.3 ms]
Range (min … max): 10.0 ms … 11.1 ms 200 runs

Range (min … max): 73.1 ms … 75.5 ms 200 runs
Summary
Perl ran
7.23 ± 0.13 times faster than Shell

As a wise man once told me, "Deleted code is debugged code!" So, move
the functions that are shared between merge-recursive and merge-ort from
the former to the latter, and then debug the remainder of
merge-recursive.[ch].
Joking aside, merge-ort was always intended to replace merge-recursive.
It has numerous advantages over merge-recursive (operates much faster,
can operate without a worktree or index, and fixes a number of known
bugs and suboptimal merges). Since we have now replaced all callers of
merge-recursive with equivalent functions from merge-ort, move the
shared functions from the former to the latter, and delete the remainder
of merge-recursive.[ch].

The `struct reftable_reader` subsystem encapsulates a table that has
been read from the disk. As such, the current name of that structure is
somewhat hard to understand as it only talks about the fact that we read
something from disk, without really giving an indicator _what_ that is.
Furthermore, this naming schema doesn't really fit well into how the
other structures are named: `reftable_merged_table`, `reftable_stack`,
`reftable_block` and `reftable_record` are all named after what they
encapsulate.
Rename the subsystem to `reftable_table`, which directly gives a hint
that the data structure is about handling the individual tables part of
the stack.
While this change results in a lot of churn, it prepares for us exposing
the APIs to third-party callers now that the reftable library is a
standalone library that can be linked against by other projects.

The Perl interpreter used to be a strict dependency for running our test
suite. This requirement is explicit in the Meson build system, where we
require Perl to be present unless tests have been disabled.
With the preceding commits we have loosened this restriction so that it
is now possible to run tests when Perl is unavailable. Loosen the above
requirement accordingly.

Almost all of the tools we discover during the build process need to be
native programs. There are only a handful of exceptions, which typically
are programs whose paths we need to embed into the resulting executable
so that they can be found on the target system when Git executes. While
this distinction typically doesn't matter, it does start to matter when
considering cross-compilation where the build and target machines are
different.
Meson supports cross-compilation via so-called machine files. These
machine files allow the user to override parameters for the build
machine, but also for the target machine when cross-compiling. Part of
the machine file is a section that allows the user to override the
location where binaries are to be found in the target system. The
following machine file would for example override the path of the POSIX
shell:
[binaries]
sh = '/usr/xpg4/bin/sh'
It can be handed over to Meson via `meson setup --cross-file`.
We do not handle this correctly right now though because we don't know
to distinguish binaries for the build and target hosts at all. Address
this by explicitly passing the `native:` parameter to `find_program()`:
- When set to `true`, we get binaries discovered on the build host.
- When set to `false`, we get either the path specified in the
machine file. Or, if no machine file exists or it doesn't specify
the binary path, then we fall back to the binary discovered on the
build host.
As mentioned, only a handful of binaries are not native: only the system
shell, Python and Perl need to be treated specially here.

The "curl" option controls whether or not a couple of features that
depend on curl shall be included. Most importantly, these features
include the HTTP remote helpers, which are rather quintessential for a
well-functioning Git installation. So while the dependency can in theory
be dropped, most users wouldn't consider the resulting installation to
be fully functional.
The "curl" option is defined as a feature, which means that it can be
"enabled", "disabled" or "auto", which has the effect that the feature
will be enabled if the dependency itself has been found. While most of
the other features have "auto" as default value, the "curl" option is
set to "enabled" by default due to it being so important. Consequently,
autoconfiguration of Git will fail by default if the library cannot be
found.
There is a bug though with how we handle the option in case the user
overrides the feature with `meson setup -Dcurl=auto`: while we will try
to find the library in that case, we won't ever use it because we later
on check for `get_option('curl').enabled()` when deciding whether or not
we want to build dependent sources. But `enabled()` only returns true if
the option has the value "enabled", for "auto" it will return false.
Fix the issue by instead checking for `curl.found()`, which is only true
if the library has been found. And as we only try to find the library
when `get_option('curl')` returns "true" or "auto" this is exactly what
we want.
