In c7c4bdeccf (run-command API: remove "env" member, always use
"env_array", 2021-11-25), there was a push to replace
cld.env = env->v;
with
strvec_pushv(&cld.env_array, env->v);
The conversion in c7c4bdeccf was mostly plug-and-play, with the snag
that some instances of strvec_pushv() became guarded with a NULL check
to ensure that the second argument was non-NULL.
This conversion was slightly over-eager to add a conditional in
builtin/receive-pack.c::unpack(), since we know at the point that we
add the result of `tmp_objdir_env()` into the child process's
environment, that `tmp_objdir` is non-NULL.
This follows from the conditional just before our strvec_pushv() call
(which returns from the function if `tmp_objdir` was NULL), as well as
the call to tmp_objdir_add_as_alternate() just below, which relies on
its argument (`tmp_objdir`) being non-NULL.
In the meantime, this extra conditional isn't hurting anything. But it
is redundant and thus unnecessarily confusing. So let's remove it.

When 7dce19d3 (fetch/pull: Add the --recurse-submodules option,
2010-11-12) introduced the "--recurse-submodule" option, the
approach taken was to perform fetches in submodules only once, after
all the main fetching (it may usually be a fetch from a single
remote, but it could be fetching from a group of remotes using
fetch_multiple()) succeeded. Later we added "--all" to fetch from
all defined remotes, which complicated things even more.
If your project has a submodule, and you try to run "git fetch
--recurse-submodule --all", you'd see a fetch for the top-level,
which invokes another fetch for the submodule, followed by another
fetch for the same submodule. All but the last fetch for the
submodule come from a "git fetch --recurse-submodules" subprocess
that is spawned via the fetch_multiple() interface for the remotes,
and the last fetch comes from the code at the end.
Because recursive fetching from submodules is done in each fetch for
the top-level in fetch_multiple(), the last fetch in the submodule
is redundant. It only matters when fetch_one() interacts with a
single remote at the top-level.
While we are at it, there is one optimization that exists in dealing
with a group of remote, but is missing when "--all" is used. In the
former, when the group turns out to be a group of one, instead of
spawning "git fetch" as a subprocess via the fetch_multiple()
interface, we use the normal fetch_one() code path. Do the same
when handing "--all", if it turns out that we have only one remote
defined.

This switch statement was recently added to make it clear that
unpack_loose_header() returns an enum value, not an int. This adds
complications for future developers if that enum gains new values, since
that developer would need to add a case statement to this switch for
little real value.
Instead, we can revert back to an 'if' statement, but make the enum
explicit by using "!= ULHR_OK" instead of assuming it has the numerical
value zero.

Let's likewise change code in various other places that was hardcoding
checks for "'/' || '\\'" with the new is_xplatform_dir_sep(). As can

Libcurl has a CURLOPT_RESOLVE easy option that allows
the result of hostname resolution in the following
format to be passed:
[+]HOST:PORT:ADDRESS[,ADDRESS]
This way, redirects and everything operating against the
HOST+PORT will use the provided ADDRESS(s).
The following format is also allowed to stop using
hostname resolutions that have already been passed:
-HOST:PORT
See https://curl.se/libcurl/c/CURLOPT_RESOLVE.html for
more details.
Let's add a corresponding "http.curloptResolve" config
option that takes advantage of CURLOPT_RESOLVE.
Each value configured for the "http.curloptResolve" key
is passed "as is" to libcurl through CURLOPT_RESOLVE, so
it should be in one of the above 2 formats. This keeps
the implementation simple and makes us consistent with
libcurl's CURLOPT_RESOLVE, and with curl's corresponding
`--resolve` command line option.
The implementation uses CURLOPT_RESOLVE only in

When a Git server responds to a fetch request, it may send optional
sections before the packfile section. To handle this, the Git client
calls packet_reader_peek() (see process_section_header()) in order to
see what's next without consuming the line.
However, as implemented, Git errors out whenever what's peeked is not an
ordinary line. This is not only unexpected (here, we only need to know
whether the upcoming line is the section header we want) but causes
errors to include the name of a section header that is irrelevant to the
cause of the error. For example, at $DAYJOB, we have seen "fatal: error
reading section header 'shallow-info'" error messages when none of the
repositories involved are shallow.
Therefore, fix this so that the peek returns 1 if the upcoming line is
the wanted section header and nothing else. Because of this change,
reader->line may now be NULL later in the function, so update the error
message printing code accordingly.

bdc77d1d68 (Add a function to determine whether a path is owned by the
current user, 2022-03-02) checks for the effective uid of the running
process using geteuid() but didn't account for cases where that user was
root (because git was invoked through sudo or a compatible tool) and the
original uid that repository trusted for its config was no longer known,
therefore failing the following otherwise safe call:
guy@renard ~/Software/uncrustify $ sudo git describe --always --dirty
[sudo] password for guy:
fatal: unsafe repository ('/home/guy/Software/uncrustify' is owned by someone else)
Attempt to detect those cases by using the environment variables that
those tools create to keep track of the original user id, and do the
ownership check using that instead.
This assumes the environment the user is running on after going
privileged can't be tampered with, and also adds code to restrict that
the new behavior only applies if running as root, therefore keeping the
most common case, which runs unprivileged, from changing, but because of
that, it will miss cases where sudo (or an equivalent) was used to change
to another unprivileged user or where the equivalent tool used to raise
privileges didn't track the original id in a sudo compatible way.
Because of compatibility with sudo, the code assumes that uid_t is an
unsigned integer type (which is not required by the standard) but is used
that way in their codebase to generate SUDO_UID. In systems where uid_t
is signed, sudo might be also patched to NOT be unsigned and that might
be able to trigger an edge case and a bug (as described in the code), but
it is considered unlikely to happen and even if it does, the code would
just mostly fail safely, so there was no attempt either to detect it or
prevent it by the code, which is something that might change in the future,
based on expected user feedback.

Originally reported after release of v2.35.2 (and other maint branches)
for CVE-2022-24765 and blocking otherwise harmless commands that were
done using sudo in a repository that was owned by the user.
Add a new test script with very basic support to allow running git
commands through sudo, so a reproduction could be implemented and that
uses only `git status` as a proxy of the issue reported.
Note that because of the way sudo interacts with the system, a much
more complete integration with the test framework will require a lot
more work and that was therefore intentionally punted for now.
The current implementation requires the execution of a special cleanup
function which should always be kept as the last "test" or otherwise
the standard cleanup functions will fail because they can't remove
the root owned directories that are used. This also means that if
failures are found while running, the specifics of the failure might
not be kept for further debugging and if the test was interrupted, it
will be necessary to clean the working directory manually before
restarting by running:
$ sudo rm -rf trash\ directory.t0034-root-safe-directory/
The test file also uses at least one initial "setup" test that creates
a parallel execution directory under the "root" sub directory, which
should be used as top level directory for all repositories that are
used in this test file. Unlike all other tests the repository provided
by the test framework should go unused.
Special care should be taken when invoking commands through sudo, since
the environment is otherwise independent from what the test framework
setup and might have changed the values for HOME, SHELL and dropped
several relevant environment variables for your test. Indeed `git status`
was used as a proxy because it doesn't even require commits in the
repository to work and usually doesn't require much from the environment
to run, but a future patch will add calls to `git init` and that will
fail to honor the default branch name, unless that setting is NOT
provided through an environment variable (which means even a CI run
could fail that test if enabled incorrectly).
A new SUDO prerequisite is provided that does some sanity checking
to make sure the sudo command that will be used allows for passwordless
execution as root without restrictions and doesn't mess with git's
execution path. This matches what is provided by the macOS agents that
are used as part of GitHub actions and probably nowhere else.
Most of those characteristics make this test mostly only suitable for
CI, but it might be executed locally if special care is taken to provide
for all of them in the local configuration and maybe making use of the
sudo credential cache by first invoking sudo, entering your password if
needed, and then invoking the test with:
$ GIT_TEST_ALLOW_SUDO=YES ./t0034-root-safe-directory.sh
If it fails to run, then it means your local setup wouldn't work for the
test because of the configuration sudo has or other system settings, and
things that might help are to comment out sudo's secure_path config, and
make sure that the account you are using has no restrictions on the
commands it can run through sudo, just like is provided for the user in
the CI.
For example (assuming a username of marta for you) something probably
similar to the following entry in your /etc/sudoers (or equivalent) file:
marta ALL=(ALL:ALL) NOPASSWD: ALL

Since 4c28e4ada0 (commit: die before asking to edit the log
message, 2010-12-20), we have been "leaking" the "author_ident" when
prepare_to_commit() fails. Instead of returning from right there,
introduce an exit status variable and jump to the clean-up label
at the end.
Instead of explicitly releasing the resource with strbuf_release(),
mark the variable with UNLEAK() at the end, together with two other
variables that are already marked as such. If this were in a
utility function that is called number of times, but these are
different, we should explicitly release resources that grow
proportionally to the size of the problem being solved, but
cmd_commit() is like main() and there is no point in spending extra
cycles to release individual pieces of resource at the end, just
before process exit will clean everything for us for free anyway.
This fixes a leak demonstrated by e.g. "t3505-cherry-pick-empty.sh",
but unfortunately we cannot mark it or other affected tests as passing
now with "TEST_PASSES_SANITIZE_LEAK=true" as we'll need to fix many
other memory leaks before doing so.
Incidentally there are two tests that always passes the leak checker
with or without this change. Mark them as such.

This would happen as we stat'd the non-existing
".git/objects/info/commit-graph" file. Let's fix mark_commit_graphs()
to check the stat()'s return value, and while we're at it fix another
case added in the same commit to do the same.
The caller in expire_commit_graphs() would have been less likely to
run into this, as it's operating on files it just got from readdir(),
but it could still happen due to a race with e.g. a concurrent "rm
-rf" of the commit-graph files.

Fix a regression in my 3b6a8db3b0 (object-file.c: use "enum" return
type for unpack_loose_header(), 2021-10-01) revealed both by running
the test suite with --valgrind, and with the amended "git fsck" test.
In practice this regression in v2.34.0 caused us to claim that we
couldn't parse the header, as opposed to not being able to unpack
it. Before the change in the C code the test_cmp added here would emit:
-error: unable to unpack header of ./objects/e6/9de29bb2d1d6434b8b29ae775ad8c2e48c5391
+error: unable to parse header of ./objects/e6/9de29bb2d1d6434b8b29ae775ad8c2e48c5391
I.e. we'd proceed to call parse_loose_header() on the uninitialized
"hdr" value, and it would have been very unlikely for that
uninitialized memory to be a valid git object.
The other callers of unpack_loose_header() were already checking the
enum values exhaustively. See 3b6a8db3b0 and
5848fb11ac (object-file.c: return ULHR_TOO_LONG on "header too long",
2021-10-01).

Fix a regression in b7d11a0f5d (tests: exercise the RUNTIME_PREFIX
feature, 2021-07-24) where tests that want to set up and test a "git"
wrapper in $PATH conflicted with the t/bin/valgrind wrapper(s) doing
the same.

When the "--add-file" option is used to add the contents from an
untracked file to the archive, the permission mode bits for these
files are sent to the archive-backend specific "write_entry()"
method as-is. We normalize the mode bits for tracked files way
before we pass them to the write_entry() method; we should do the
same here.
This is not strictly needed for "tar" archive-backend, as it has its
own code to further clean them up, but "zip" archive-backend is not
so well prepared.

Fix a bug in "git pull" where `submodule.recurse` is preferred over
`fetch.recurseSubmodules` when performing a fetch
(Documentation/config/fetch.txt says that `fetch.recurseSubmodules`
should be preferred.). Do this by passing the value of the
"--recurse-submodules" CLI option to the underlying fetch, instead of
passing a value that combines the CLI option and config variables.
In other words, this bug occurred because builtin/pull.c is conflating
two similar-sounding, but different concepts:
- Whether "git pull" itself should care about submodules e.g. whether it
should update the submodule worktrees after performing a merge.
- The value of "--recurse-submodules" to pass to the underlying "git
fetch".
Thus, when `submodule.recurse` is set, the underlying "git fetch" gets
invoked with "--recurse-submodules[=value]", overriding the value of
`fetch.recurseSubmodules`.
An alternative (and more obvious) approach to fix the bug would be to
teach "git pull" to understand `fetch.recurseSubmodules`, but the
proposed solution works better because:
- We don't maintain two identical config-parsing implementions in "git
pull" and "git fetch".
- It works better with other commands invoked by "git pull" e.g. "git
merge" won't accidentally respect `fetch.recurseSubmodules`.
