Commit 01aff0a (apply: correctly reverse patch's pre- and post-image
mode bits, 2023-12-26) revised reverse_patches() to maintain the desired
property that when only one of patch::old_mode and patch::new_mode is
set, the mode will be carried in old_mode. That property is generally
correct, with one notable exception: when creating a file, only new_mode
will be set. Since reversing a deletion results in a creation, new_mode
must be set in that case.
Omitting handling for this case means that reversing a patch that
removes an executable file will not result in the executable permission
being set on the re-created file. Existing test coverage for file modes
focuses only on mode changes of existing files.
Swap old_mode and new_mode in reverse_patches() for what's represented
in the patch as a file deletion, as it is transformed into a file
creation under reversal. This causes git apply --reverse to set the
executable permission properly when re-creating a deleted executable
file.
Add tests ensuring that git apply sets file modes correctly on file
creation, both in the forward and reverse directions.

There is no test covering what commit 01aff0a (apply: correctly reverse
patch's pre- and post-image mode bits, 2023-12-26) addressed. Prior to
that commit, git apply was erroneously unaware of a file's expected mode
while reverse-patching a file whose mode was not changing.
Add the missing test coverage to assure that git apply is aware of the
expected mode of a file being patched when the patch does not indicate
that the file's mode is changing. This is achieved by arranging a file
mode so that it doesn't agree with patch being applied, and checking git
apply's output for the warning it's supposed to raise in this situation.
Test in both reverse and normal (forward) directions.

Clarify what happens when an object exists in more than one pack, but
not in the preferred pack. "git multi-pack-index repack" relies on ties
for objects that are not in the preferred pack being resolved in favor
of the newest pack that contains a copy of the object. If ties were
resolved in favor of the oldest pack as the current documentation
suggests the multi-pack index would not reference any of the objects in
the pack created by "git multi-pack-index repack".

nth_midxed_pack_int_id() returns the index of the pack file in the multi
pack index's list of packfiles that the specified object. The index is
returned as a uint32_t. Storing this in an int will make the index
negative if the most significant bit is set. Fix this by using uint32_t
as the rest of the code does. This is unlikely to be a practical problem
as it requires the multipack index to reference 2^31 packfiles.

On a 64 bit system the calculation
p->pack_size * pack_info[i].referenced_objects
could overflow. If a pack file contains 2^28 objects with an average
compressed size of 1KB then the pack size will be 2^38B. If all of the
objects are referenced by the multi-pack index the sum above will
overflow. Avoid this by using shifted integer arithmetic and changing
the order of the calculation so that the pack size is divided by the
total number of objects in the pack before multiplying by the number of
objects referenced by the multi-pack index. Using a shift of 14 bits
should give reasonable accuracy while avoiding overflow for pack sizes
less that 1PB.

On a 32 bit system "git multi-pack-index --repack --batch-size=120M"
failed with
fatal: size_t overflow: 6038786 * 1289
The calculation to estimated size of the objects in the pack referenced
by the multi-pack-index uses st_mult() to multiply the pack size by the
number of referenced objects before dividing by the total number of
objects in the pack. As size_t is 32 bits on 32 bit systems this
calculation easily overflows. Fix this by using 64bit arithmetic instead.
Also fix a potential overflow when caluculating the total size of the
objects referenced by the multipack index with a batch size larger
than SIZE_MAX / 2. In that case
total_size += estimated_size
can overflow as both total_size and estimated_size can be greater that
SIZE_MAX / 2. This is addressed by using saturating arithmetic for the
addition. Although estimated_size is of type uint64_t by the time we
reach this sum it is bounded by the batch size which is of type size_t
and so casting estimated_size to size_t does not truncate the value.

During git-receive-pack(1), connectivity of the object graph is
validated to ensure that the received packfile does not leave the
repository in a broken state. This is done via git-rev-list(1) and
walking the objects, which can be expensive for large repositories.
Generally, this check is critical to avoid an incomplete received
packfile from corrupting a repository. Server operators may have
additional knowledge though around exactly how Git is being used on the
server-side which can be used to facilitate more efficient connectivity
computation of incoming objects.
For example, if it can be ensured that all objects in a repository are
connected and do not depend on any missing objects, the connectivity of
newly written objects can be checked by walking the object graph
containing only the new objects from the updated tips and identifying
the missing objects which represent the boundary between the new objects
and the repository. These boundary objects can be checked in the
canonical repository to ensure the new objects connect as expected and
thus avoid walking the rest of the object graph.
Git itself cannot make the guarantees required for such an optimization
as it is possible for a repository to contain an unreachable object that
references a missing object without the repository being considered
corrupt.
Introduce the --skip-connectivity-check option for git-receive-pack(1)
which bypasses this connectivity check to give more control to the
server-side. Note that without proper server-side validation of newly
received objects handled outside of Git, usage of this option risks
corrupting a repository.

Commit f5e3c6c57d ("meson: do a full usage-based compile check for
sysinfo", 2025-04-25) updated the 'sysinfo()' check, as part of the
meson build, due to the failure of the check on Solaris. Prior to
that commit, the meson build only checked the availability of the
'<sys/sysinfo.h>' header file. On Solaris, both the header and the
'sysinfo()' function exist, but are completely unrelated to the same
function on Linux (and cygwin).
Commit 50dec7c566 ("config.mak.uname: add sysinfo() configuration for
cygwin", 2025-04-17) added a similar 'sysinfo()' check to the autoconf
build. This check looked for the 'sysinfo()' function itself, rather
than just the header, but it will fail (incorrectly set HAVE_SYSINFO)
for the same reason.
In order to correctly identify the 'sysinfo()' function we require as
part of 'git-gc' (used in the 'total_ram() function), we also upgrade
to a compilation check, in a similar way to the meson commit. Note that
since commit c9a51775a3 ("builtin/gc.c: correct RAM calculation when
using sysinfo", 2025-04-17) both the 'totalram' and 'mem_unit' fields
of the 'struct sysinfo' are used, so the new check includes both of
those fields in the compile check.

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".
