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.

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.

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.

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.

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.

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.

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.

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.

We set up libcurl via the `libgit_dependencies` variable, which gets
propagated into every user of the `libgit` dependency. This is not
necessary though, as most of our executables aren't even supposed to
link against libcurl.
Fix this by only propagating include directories as a libgit dependency
and propagating the full curl dependency via `libgit_curl`.

We've got a set of common source files that we use for those executables
that link against libcurl. The setup is somewhat repetitive though.
Simplify it by declaring a `libgit_curl` dependency that bundles all of
it together.
Note that we don't include curl itself as a dependency. This is because
we already pull it in transitively via the libgit dependency, which is
unfortunate because libgit itself shouldn't actually link against curl
in the first place. This will get fixed in the next commit.

The "common-main.c" file is used by multiple executables. In order to
make it easy to set it up we have created a separate library that these
executables can link against. All of these executables also want to link
against `libgit.a` though, which makes it necessary to specify both of
these as dependencies for every executable.
Simplify this a bit by declaring the library as a source dependency:
instead of creating a static library, we now instead compile the common
set of files into each executable separately.

When setting up `libgit.a` we first create the static library itself,
and then declare it as part of a dependency such that compile arguments,
include directories and transitive dependencies get propagated to the
users of that library. As such, the static library isn't expected to be
used by anything but the declared dependency.
Inline the static library so that we don't even use a separate variable
for it. This avoids any kind of confusion that may arise and clarifies
how the library is supposed to be used.

When OpenSSL isn't provided by the system we know to fall back to the
subproject wrapper. This is especially helpful on Windows systems, where
you typically don't have OpenSSL available, in order to reduce the
number of required dependencies.
The fallback is broken though when the OpenSSL backend is set to 'auto'
as we end up calling `dependency('openssl', required: false)` in that
case, which implicitly disables falling back to the wrapper.
Fix the issue by re-allowing the fallback in case either OpenSSL is
required or in case the backend is set to 'auto'. While at it, fix
reporting of the backend in case the user asked us to pick no HTTPS
backend at all.

When the runtime prefix option is enabled, Git is built such that it
knows to locate its binaries relative to the directory a binary is being
executed from. This requires us to figure out relative paths, which is
handled in `system_prefix()` by trying to strip a couple of well-known
paths.
One of these paths, GIT_EXEC_PATH, is expected to be absolute when
runtime prefixes are enabled, but relative otherwise. And while our
Makefile gets this correctly, in Meson we always wire up the absolute
path, which may result in us not being able to find binaries.
Fix this by conditionally injecting the paths depending on whether or
not the `runtime_prefix` option is enabled.

Submodule merges are, in general, similar to other merges based on oid
three-way-merge. When a conflict happens, however, Git has two special
cases (introduced in 68d03e4a6e44) on handling the conflict before
yielding it to the user. From the merge-ort and merge-recursive sources:
- "Case #1: a is contained in b or vice versa": both strategies try to
perform a fast-forward in the submodules if the commit referred by the
conflicted submodule is descendant of another;
- "Case #2: There are one or more merges that contain a and b in the
submodule. If there is only one, then present it as a suggestion to the
user, but leave it marked unmerged so the user needs to confirm the
resolution."
Add a small paragraph on merge-strategies.adoc describing this behavior.

For an extended period of time, we've enabled libcurl's netrc
functionality, which will read credentials from the netrc file if none
are provided. Unfortunately, we have also not documented this fact or
written any tests for it, but people have come to rely on it.
In 610cbc1dfb ("http: allow authenticating proactively", 2024-07-10), we
accidentally broke the ability of users to use the netrc file for the
WebDAV-based HTTP protocol. Notably, it works on the initial request
but does not work on subsequent requests, which causes failures because
that version of the protocol will necessarily make multiple requests.
This happens because curl_empty_auth_enabled never returns -1, only 0 or
1, and so if http.proactiveAuth is not enabled, the username and
password are always set to empty credentials, which prevents libcurl's
fallback to netrc from working. However, in other cases, the server
continues to get a 401 response and the credential helper is invoked,
which is the normal behavior, so this was not noticed earlier.
To fix this, change the condition to check for enabling empty auth and
also not having proactive auth enabled, which should result in the
username and password not being set to a single colon in the typical
case, and thus the netrc file being used.
