As per
https://github.com/git-for-windows/git/issues/4350#issuecomment-1485041503,
the major block for upgrading Git for Windows' OpenSSL from v1.1 to v3
is the tricky part where such an upgrade would break `git fetch`/`git
clone` and `git push` because the libcurl depends on the OpenSSL DLL,
and the major version bump will _change_ the file name of said DLL.
To overcome that, the plan is to build libcurl flavors for each
supported SSL/TLS backend, aligning with the way MSYS2 builds libcurl,
then switch Git for Windows' SDK to the Secure Channel-flavored libcurl,
and teach Git to look for the specific flavor of libcurl corresponding
to the `http.sslBackend` setting (if that was configured).
Here is the PR to teach Git that trick.
This implements the Windows-specific support code, because everything is
slightly different on Windows, even loading shared libraries.
Note: I specifically do _not_ use the code from
`compat/win32/lazyload.h` here because that code is optimized for
loading individual functions from various system DLLs, while we
specifically want to load _many_ functions from _one_ DLL here, and
distinctly not a system DLL (we expect libcurl to be located outside
`C:\Windows\system32`, something `INIT_PROC_ADDR` refuses to work with).
Also, the `curl_easy_getinfo()`/`curl_easy_setopt()` functions are
declared as vararg functions, which `lazyload.h` cannot handle. Finally,
we are about to optionally override the exact file name that is to be
loaded, which is a goal contrary to `lazyload.h`'s design.

This compile-time option allows to ask Git to load libcurl dynamically
at runtime.
Together with a follow-up patch that optionally overrides the file name
depending on the `http.sslBackend` setting, this kicks open the door for
installing multiple libcurl flavors side by side, and load the one
corresponding to the (runtime-)configured SSL/TLS backend.

In subsequent patches we'll be turning `struct odb_source_loose` into a

struct out of "object-file.c" and into "odb/source-loose.c".
This detaches the implementation of the loose object source from the
generic object file code, following the same convention already used by
the "files" and "in-memory" sources.
No functional changes are intended.

Next to our typical object database sources, each object database also
has an implicit source of "cached" objects. These cached objects only
exist in memory and some use cases:
- They contain evergreen objects that we expect to always exist, like
for example the empty tree.
- They can be used to store temporary objects that we don't want to
persist to disk, which is used by git-blame(1) to create a fake
worktree commit.
Overall, their use is somewhat restricted though. For example, we don't
provide the ability to use it as a temporary object database source that
allows the user to write objects, but discard them after Git exists. So
while these cached objects behave almost like a source, they aren't used
as one.
This is about to change over the following commits, where we will turn
cached objects into a new "in-memory" source. This will allow us to use
it exactly the same as any other source by providing the same common
interface as the "files" source.
For now, the in-memory source only hosts the cached objects and doesn't
provide any logic yet. This will change with subsequent commits, where
we move respective functionality into the source.

Introduce a new builtin for pretty formatting one revision expression
per line or commit object names found in running text.
Sometimes you want to format commits. Most of the time you’re
walking the graph, e.g. getting a range of commits like
`master..topic`. That’s a job for git-log(1).
But there are times when you want to format commits that you encounter
on demand:
• Full hashes in running text that you might want to pretty-print
• git-last-modified(1) outputs full hashes that you can do the same
with
• git-cherry(1) has `-v` for commit subject, but maybe you want
something else?
But now you can’t use git-log(1), git-show(1), or git-rev-list(1):
• You can’t feed commits piecemeal to these commands, one input
for one output; they block until standard in is closed
• You can’t feed a list of possibly duplicate commits, like the output
of git-last-modified(1); they effectively deduplicate the output
Beyond these two points there’s also the input massage problem: you
cannot feed mixed input (revisions mixed with arbitrary text).
One might hope that git-cat-file(1) can save us. But it doesn’t
support pretty formats.
But there is one command that already both handles revisions as
arguments, revisions on standard input, and even revisions mixed in
with arbitrary text. Namely git-name-rev(1): the command for outputting
symbolic names for commits.
We made some room in `builtin/name-rev.c` two commits ago. Let’s
now add this new git-format-rev(1) command. Taking inspiration from
git-name-rev(1), there are two modes:
• revs: like git-name-rev(1) in argv mode, but one revision per line
on standard in
• text: like git-name-rev(1) with `--annotate-stdin`
***
We need to add this command to the exception list in
`t/t1517-outside-repo.sh` because it uses “EXPERIMENTAL!”
in the usage line.

To test Git's behavior with very large pack files, we need a way to
generate such files quickly.
A naive approach using only readily-available Git commands would take
over 10 hours for a 4GB pack file, which is prohibitive.
Side-stepping Git's machinery and actual zlib compression by writing
uncompressed content with the appropriate zlib header makes things
much faster. The fastest method using this approach generates many
small, unreachable blob objects and takes about 1.5 minutes for 4GB.
However, this cannot be used because we need to test git clone, which
requires a reachable commit history.
Generating many reachable commits with small, uncompressed blobs takes
about 4 minutes for 4GB. But this approach 1) does not reproduce the
issues we want to fix (which require individual objects larger than
4GB) and 2) is comparatively slow because of the many SHA-1
calculations.
The approach taken here generates a single large blob (filled with NUL
bytes), along with the trees and commits needed to make it reachable.
This takes about 2.5 minutes for 4.5GB, which is the fastest option
that produces a valid, clonable repository with an object large enough
to trigger the bugs we want to test.

Git commands can accept a rather wide variety of URLs syntaxes.
The range of accepted inputs might expand even more in the future.
This makes the parsing of URL components difficult since standard URL
parsers cannot be used. Extracting the components of a git URL would
require implementing all the schemes that git itself supports, not to
mention tracking its development continuously in case new URL schemes
are added.
The url-parse builtin command is designed to solve this problem
by exposing git's native URL parsing facilities as a plumbing command.
Other programs can then call upon git itself to parse the git URLs
and extract their components. This should be quite useful for scripts.

Our breaking changes document says that we'll enable Rust by default in

NO_RUST to enable it by default and update the help text accordingly.
Similarly, for Meson, enable the option by default and do not
automatically disable it if Cargo is missing, since the goal is to help
users find where they are likely to have problems in the future.
Update our CI tests to swap out the single Linux job with Rust to a
single job without, both for Makefile and Meson. Similarly, update the
Windows Makefile job to not use Rust, while the Meson job (which does

Teach "git hook run" and "git hook list" to reject hook event names
that are not recognized by Git. This helps catch typos such as
"prereceive" when "pre-receive" was intended, since in 99% of the
cases users want known (already-existing) hook names.
The list of known hooks is derived from the generated hook-list.h
(built from Documentation/githooks.adoc). This is why the Makefile
is updated, so builtin/hook.c depends on hook-list.h. In meson the
header is already a dependency for all builtins, no change required.
The "--allow-unknown-hook-name" flag can be used to bypass this check.

According to its readme, the "contrib/" directory's main intent is to
collect stuff that is not an official part of Git, either because it is
too specialized or because it is still considered experimental. The
reality tells a bit of a different story though: while it _does_ contain
such things, it also contains other things:
- Our credential helpers, which are being distributed by many
packagers nowadays and which can be considered "stable".
- A bunch of tooling that relates to our build and test
infrastructure.
Especially the second category is somewhat of a sore spot. You really
wouldn't expect build-related tooling to be considered an optional part
of Git. Quite the opposite.
Create a new top-level "tools/" directory to fix this discrepancy. This
directory will contain all kind of tools that are related to our build
infrastructure and that Git developers are likely to use day to day.
For now, this directory doesn't contain anything yet except for a
readme and a Meson skeleton. This will change in subsequent commits.

The past few commits fixed some cases where we leak memory allocated by
mmap(). Building with SANITIZE=leak doesn't detect these because it
covers only heap buffers allocated by malloc().
But if we build with NO_MMAP, our compat mmap() implementation will
allocate a heap buffer and pread() into it. And thus Lsan will detect
these leaks for free.
Using NO_MMAP is less performant, of course, since we have to use extra
memory and read in the whole file, rather than faulting in pages from
disk. But LSan builds are already slow, and this doesn't make them
measurably worse. Getting extra coverage for our leak-checking is worth
it.

The Meson-based build doesn't know when to rebuild config-list.h, so the
header is sometimes stale.
For example, an old build directory might have config-list.h from before
4173df5187 (submodule: introduce extensions.submodulePathConfig,
2026-01-12), which added submodule.<name>.gitdir to the list. Without
it, t9902-completion.sh fails. Regenerating the config-list.h artifact
from sources fixes the artifact and the test.
Since Meson does not have (or want) builtin support for globbing like
Make, teach generate-configlist.sh to also generate a list of
Documentation files its output depends on, and incorporate that into the
Meson build. We honor the undocumented GCC/Clang contract of outputting
empty targets for all the dependencies (like they do with -MP). That is,
generate lines like
build/config-list.h: $SOURCE_DIR/Documentation/config.adoc
$SOURCE_DIR/Documentation/config.adoc:
We assume that if a user adds a new file under
Documentation/config then they will also edit one of the existing files
to include that new file, and that will trigger a rebuild. Also mark the
generator script as a dependency.
While we're at it, teach the Makefile to use the same "the script knows
it's dependencies" logic.
For Meson, combining the following commands helps debug dependencies:
ninja -C <builddir> -t deps config-list.h
ninja -C <builddir> -t browse config-list.h
The former lists all the dependencies discovered from our output ".d"
file (the config documentation) and the latter shows the dependency on
the script itself, among other useful edges in the dependency graph.

The fix for git-credential-osxkeychain in 4580bcd235 (osxkeychain: avoid
incorrectly skipping store operation, 2025-11-14) introduced linkage
with libgit.a, and its Makefile was adjusted accordingly. However, the
build fails as of 864f55e190 because several macOS-specific refinements
were applied to the top-level Makefile and config.mak.uname, such as:
- 363837afe7 (macOS: make Homebrew use configurable, 2025-12-24)
- cee341e9dd (macOS: use iconv from Homebrew if needed and present,

- d281241518 (utf8.c: enable workaround for iconv under macOS 14/15,

Since libgit.a and its corresponding header files depend on many flags
defined in the top-level Makefile, these flags must be consistently
defined when building git-credential-osxkeychain. Continuing to manually
adjust the git-credential-osxkeychain Makefile is cumbersome and
fragile.
Define the build targets for git-credential-osxkeychain in the top-level
Makefile and modify its local Makefile to simply rely on those targets.

In a following commit, we are going to allow passing "auto" as a
<filterspec> to the `--filter=<filterspec>` option, but only for some
commands. Other commands that support the `--filter=<filterspec>`
option should still die() when 'auto' is passed.
Let's set up the "list-objects-filter-options.{c,h}" infrastructure to
support that:
- Add a new `unsigned int allow_auto_filter : 1;` flag to
`struct list_objects_filter_options` which specifies if "auto" is
accepted or not by the current command.
- Change gently_parse_list_objects_filter() to parse "auto" if it's
accepted.
- Make sure we die() if "auto" is combined with another filter.
- Update list_objects_filter_release() to preserve the
allow_auto_filter flag, as this function is often called (via
opt_parse_list_objects_filter) to reset the struct before parsing a
new value.
Let's also update `list-objects-filter.c` to recognize the new
`LOFC_AUTO` choice. Since "auto" must be resolved to a concrete filter
before filtering actually begins, initializing a filter with
`LOFC_AUTO` is invalid and will trigger a BUG().
Note that ideally combining "auto" with "auto" could be allowed, but in
practice, it's probably not worth the added code complexity. And if we
really want it, nothing prevents us to allow it in future work.
If we ever want to give a meaning to combining "auto" with a different
filter too, nothing prevents us to do that in future work either.
Also note that the new `allow_auto_filter` flag depends on the command,
not user choices, so it should be reset to the command default when
`struct list_objects_filter_options` instances are reset.
While at it, let's add a new "u-list-objects-filter-options.c" file for
`struct list_objects_filter_options` related unit tests. For now it
only tests gently_parse_list_objects_filter() though.

Test contrib/ things in CI to catch breakages before they enter the
"next" branch.
* jc/ci-test-contrib-too:
: Some of our downstream folks run more tests than we do and catch
: breakages in them, namely, where contrib/*/Makefile has "test" target.
: Let's make sure we fail upon accepting a new topic that break them in
: 'seen'.
ci: ubuntu: use GNU coreutils for dirname
test: optionally test contrib in CI
