Usman Akinyemi d9c5cfb18f builtin/ls-files: stop using `the_repository`
Remove the_repository global variable in favor of the repository
argument that gets passed in "builtin/ls-files.c".

When `-h` is passed to the command outside a Git repository, the
`run_builtin()` will call the `cmd_ls_files()` function with `repo` set
to NULL and then early in the function, `show_usage_with_options_if_asked()`
call will give the options help and exit.

Pass the repository available in the calling context to both
`expand_objectsize()` and `show_ru_info()` to remove their
dependency on the global `the_repository` variable.

Usman Akinyemi f29f1990b5 config: teach repo_config to allow `repo` to be NULL
The `repo` value can be NULL if a builtin command is run outside
any repository. The current implementation of `repo_config()` will
fail if `repo` is NULL.

If the `repo` is NULL the `repo_config()` can ignore the repository
configuration but it should read the other configuration sources like
the system-side configuration instead of failing.

Teach the `repo_config()` to allow `repo` to be NULL by calling the
`read_very_early_config()` which read config but only enumerate system
and global settings.

This will be useful in the following commits.

Junio C Hamano c268e3285d BreakingChanges: clarify the procedure
The point behind a compile-time switch is to ensure that we have a
mechanism to hide myriad of backward incompatible changes that may
be prepared and accumulated over time, yet make them available for
testing any time during the development toward the big version
boundary.  Add a few words to stress that point.

Since the document was first written, we have added the CI job that
the document anticipated us to have.  Rephrase to state the current
status.

The discussion in [*1*] made us abandon the "feature.git3" based
runtime switching of behaviour and instead adopt the compile-time
switching mechanism, but a stray sentence about runtime switching
still remained in the final text by mistake.  Remove it.

Patrick Steinhardt 028f618658 path: adjust last remaining users of `the_repository`
With the preceding refactorings we now only have a couple of implicit
users of `the_repository` left in the "path" subsystem, all of which
depend on global state via `calc_shared_perm()`. Make the dependency on
`the_repository` explicit by passing the repo as a parameter instead and
adjust callers accordingly.

Note that this change bubbles up into a couple of subsystems that were
previously declared as free from `the_repository`. Instead of marking
all of them as `the_repository`-dependent again, we instead use the
repository that is available in the calling context. There are three
exceptions though with "copy.c", "pack-write.c" and "tempfile.c".
Adjusting these would require us to adapt callsites all over the place,
so this is left for a future iteration.

Mark "path.c" as free from `the_repository`.

Patrick Steinhardt 6f3fbed8ed environment: move access to "core.hooksPath" into repo settings
The "core.hooksPath" setting is stored in a global variable and
populated via the `git_default_core_config`. This may cause issues in
the case where one is handling multiple different repositories in a
single process with different values for that config key, as we may or
may not see the correct value in that case. Furthermore, global state
blocks our path towards libification.

Refactor the code so that we instead store the value in `struct
repo_settings`. The value is computed as-needed and cached. The result
should be functionally the same as there aren't ever any code paths
where we'd execute hooks outside the context of a repository.

Note that this requires us to change the passed-in repository in the
`repo_git_path()` family of functions to be non-constant, as we call
`adjust_git_path()` there.

Patrick Steinhardt 88dd321cfe path: drop `git_path()` in favor of `repo_git_path()`
Remove `git_path()` in favor of the `repo_git_path()` family of
functions, which makes the implicit dependency on `the_repository` go
away.

Note that `git_path()` returned a string allocated via `get_pathname()`,
which uses a rotating set of statically allocated buffers. Consequently,
callers didn't have to free the returned string. The same isn't true for
`repo_common_path()`, so we also have to add logic to free the returned
strings.

This refactoring also allows us to remove `repo_common_pathv()` as well
as `get_pathname()` from the public interface.

Same as with `get_worktree_git_dir()` a couple of commits ago, the

caller because `git_path()` internally uses `get_pathname()`.

Refactor the function to instead accept a caller-provided buffer that
the path will be written into, passing on ownership to the caller. This
refactoring prepares us for the removal of `git_path()`.

Patrick Steinhardt aea7c185be gitlab-ci: fix "msvc-meson" test job succeeding despite test failures
We have recently noticed that the "msvc-meson" test job in GitLab CI
succeeds even if there are failures. This is somewhat puzzling because
we use exactly the same command as we do on GitHub Actions, and there
the jobs fail as exected.

As it turns out, this is another weirdness of the GitLab CI hosted
runner for Windows [1]: by default, even successful commands will not
make the job fail. Interestingly though, this depends on what exactly
the command is that you're running -- the MinGW-based job for example
works alright and does fail as expected.

The root cause here seems to be specific behaviour of PowerShell. The
invocation of `ForEach-Object` does not bubble up any errors in case the
invocation of `meson test` fails, and thus we don't notice the error.
This is specific to executing the command in a loop: other build steps
where we execute commands directly fail as expected.

This is because the specific version of PowerShell that we use in the
runner does not know about `PSNativeCommandUseErrorActionPreference`
yet, which controls whether native commands like "meson.exe" honor the
`ErrorActionPreference` variable. The preference has been introduced
with PowerShell 7.3 and is default-enabled since PowerShell 7.4, but
GitLab's hosted runners still seem to use PowerShell 5.1. Consequently,
when tests fail, we won't bubble up the error at all from the loop and
thus the job doesn't fail. This isn't an issue in other cases though
where we execute native commands directly, as the GitLab runner knows to
check the last error code after every command.

The same thing doesn't seem to be an issue on GitHub Actions, most
likely because it uses PowerShell 7.4. Curiously, the preference for
`PSNativeCommandUseErrorActionPreference` is disabled there, but the
jobs fail as expected regardless of that. It's puzzling, but I do not
have enough PowerShell expertise to give a definitive answer as to why
it works there.

In any case, Meson 1.8 will likely get support for slicing tests [1], so
we can eventually get rid of the whole PowerShell script. For now, work
around the issue by explicitly exiting out of the loop with a non-zero
error code if we see that Meson has failed.

Patrick Steinhardt 9350423982 gitlab-ci: restrict maximum number of link jobs on Windows
The hosted Windows runners on GitLab.com only have 7.5GB of RAM. Given
that "link.exe" provided by Microsoft Visual Studio is multi-threaded by
itself already and thus quite memory hungry this can quickly lead to
memory starvation, out-of-memory situations and thus failed CI jobs.

Fix the issue by limiting the number of concurrent linker jobs. The same
issue hasn't been observed on GitHub Actions yet, probably because it
got more than twice the amount of RAM with 16GB.

Patrick Steinhardt 2c374ea4bb meson: consistently use custom program paths to resolve programs
The calls to `find_program()` in our documentation don't use our custom
program path. This variable gets populated on Windows with the location
of Git for Windows so that we can use it to provide our build tools.
Consequently, we may not be able to find all necessary binaries on
Windows.

Adapt the calls to use the program path to fix this. While at it, drop
`required: true` arguments, which are the default anyway.

Patrick Steinhardt 3ee3a6eb52 meson: fix overwritten `git` variable
We're assigning the `git` variable in three places:

  - In "meson.build" to store the external Git executable.

  - In "meson.build" to store the compiled Git executable.

  - In "Documentation/meson.build" to store the external Git executable,
    a second time.

The last case is only needed because we overwrite the original variable
with the built version. Rename the variable used for the built Git
executable so that we don't have to resolve the external Git executable
multiple times.

Patrick Steinhardt 16c89dcf80 meson: prevent finding sed(1) in a loop
We're searching for the sed(1) executable in a loop, which will make us
try to find it multiple times. Starting with the preceding commit we
already declare a variable for that program in the top-level build file.
Use it so that we only need to search for the program once.

Patrick Steinhardt 42846efc3b meson: improve handling of `sane_tool_path` option
The `sane_tool_path` option can be used to override the PATH variable
from which the build process, tests and ultimately Git will end up
picking programs from. It is currently lacking though because we only
use it to populate the PATH environment variable for executed scripts
and for the `BROKEN_PATH_FIX` mechanism, but we don't use it to find
programs used in the build process itself.

Fix this issue by treating it similar to the Windows-specific paths,
which will make us use it both to find programs and to populate the PATH
environment variable.

To help with this fix, change the type of the option to be an array of
paths, which makes the handling a bit easier for us. It's also the
correct thing to do as the input indeed is a list of paths.

Furthermore, the option now overrides the default behaviour on Windows,
which si to pick up tools from Git for Windows. This is done so that it
becomes easier to override that default behaviour in case it's not
desired.

Patrick Steinhardt 454d79b61b meson: improve PATH handling
When locating programs required for the build we give some special
treatment to Windows systems so that we know to also look up tools
provided by a Git for Windows installation. This ensures that the build
doesn't have any prerequisites other than Microsoft Visual Studio, Meson
and Git for Windows.

Consequently, some of the programs returned by `find_program()` may not
be found via PATH, but via these extra directories. But while Meson can
use these tools directly without any special treatment, any scripts that
we execute may not be able to find those programs. To help them we thus
prepend the directories of a subset of the found programs to PATH.

This doesn't make much sense though: we don't need to prepend PATH for
any program that was found via PATH, but we really only need to do so
for programs located via the extraneous Windows-specific paths. So
instead of prepending all programs paths, we really only need to prepend
the Windows-specific paths.

Adapt the code accordingly by only prepeding Windows-specific paths to
PATH, which both simplifies the code and clarifies intent.

Patrick Steinhardt eee25bbd84 meson: drop separate version library
When building `libgit.a` we link it against a `libgit_version.a` library
that contains the version information that we inject at build time. The
intent of this is to avoid rebuilding all of `libgit.a` whenever the
version changes. But that wouldn't happen in the first place, as we know
to just rebuild the files that depend on the generated "version-def.h"
file.

This is an artifact of an earlier version of the Meson build infra that
didn't ultimately land. We didn't yet have "version-def.h", and instead
injected the version via preprocessor directives. And here we would have
rebuilt all of `libgit.a` indeed in case the version changes, because
the preprocessor directive applied to all files.

Stop building the separate library and instead add "version-def.h" to
the list of source files directly.
