running from, so that the subprocess could protect it. However...
When run from a non-main worktree, setup_git_directory() will note
that the discovered git directory
(/PATH/TO/.git/worktree/non-main-worktree) does not match
DEFAULT_GIT_DIR_ENVIRONMENT (see setup_discovered_git_dir()), and
decide to set GIT_DIR in the environment. This matters because...
Whenever git is run with the GIT_DIR environment variable set, and
GIT_WORK_TREE not set, it presumes that '.' is the working tree. So...
This combination results in the subcommand being very confused about
the working tree. Fix it by also setting the GIT_WORK_TREE environment
variable along with setting cmd.dir.
A possibly more involved fix we could consider for later would be to
make setup.c set GIT_WORK_TREE whenever (a) it discovers both the git
directory and the working tree and (b) it decides to set GIT_DIR in the
environment. I did not attempt that here as such would be too big of a
change for a 2.35.1 release.

When cloning a branchless and tagless but not refless remote using
protocol v0 or v1, Git calls transport_fetch_refs() with an empty ref
list. This makes the clone fail with the message "remote transport
reported error".
Git should have refrained from calling transport_fetch_refs(), just like
it does in the case that the remote is refless. Therefore, teach Git to
do this.
In protocol v2, this does not happen because the client passes
ref-prefix arguments that filter out non-branches and non-tags in the
ref advertisement, making the remote appear empty.
Note that this bug concerns logic in builtin/clone.c and only affects
cloning, not fetching.

We are about to introduce such additional checks, and indeed, t1091

When 9081a421 (checkout: fix "branch info" memory leaks, 2021-11-16)
cleaned up existing memory leaks, we added an unrelated sanity check
to ensure that a local branch is truly local and not a symref to
elsewhere that dies with BUG() otherwise. This was misguided in two
ways. First of all, such a tightening did not belong to a leak-fix
patch. And the condition it detected was *not* a bug in our program
but a problem in user data, where warning() or die() would have been
more appropriate.
As the condition is not fatal (the result of computing the local
branch name in the code that is involved in the faulty check is only
used as a textual label for the commit), let's revert the code to
the original state, i.e. strip "refs/heads/" to compute the local
branch name if possible, and otherwise leave it NULL. The consumer
of the information in merge_working_tree() is prepared to see NULL
in there and act accordingly.

When creating the sparse-checkout file, Git does not create the leading
directory, "$GIT_DIR/info", if it does not exist. This causes problems
if the repository does not have that directory. Therefore, ensure that
the leading directory is created.
This is the only "open" in builtin/sparse-checkout.c that does not have
a leading directory check. (The other one in write_patterns_and_update()
does.)
Note that the test needs to explicitly specify a template when running
"git init" because the default template used in the tests has the
"info/" directory included.

The trace2 subsystem can inherit certain information from parent
processes via environment variables; e.g., the parent command name and
session ID. This allows trace2 to note when a command is the child
process of another Git process, and to adjust various pieces of output
accordingly.
This behavior breaks certain tests that examine trace2 output when the
tests run as a child of another git process, such as in `git rebase -x
"make test"`.
While we could fix this by unsetting the relevant variables in the
affected tests (currently t0210, t0211, t0212, and t6421), this would
leave other tests vulnerable to similar breakage if new test cases are
added which inspect trace2 output. So fix this in general by unsetting
GIT_TRACE2_PARENT_NAME and GIT_TRACE2_PARENT_SID in test-lib.sh.

`git fetch --negotiate-only` is an implementation detail of push
negotiation and, unlike most `git fetch` invocations, does not actually
update the main repository. Thus it should not update submodules even
if submodule recursion is enabled.
This is not just slow, it is wrong e.g. push negotiation with
"submodule.recurse=true" will cause submodules to be updated because it
invokes `git fetch --negotiate-only`.
Fix this by disabling submodule recursion if --negotiate-only was given.
Since this makes --negotiate-only and --recurse-submodules incompatible,
check for this invalid combination and die.
This does not use the "goto cleanup" introduced in the previous commit
because we want to recurse through submodules whenever a ref is fetched,
and this can happen without introducing new objects.

This is a feature that supports config file inclusion conditional on
whether the repo has a remote with a URL that matches a glob.
Similar to my previous work on remote-suggested hooks [1], the main
motivation is to allow remote repo administrators to provide recommended
configs in a way that can be consumed more easily (e.g. through a
package installable by a package manager - it could, for example,
contain a file to be included conditionally and a post-install script
that adds the include directive to the system-wide config file).
In order to do this, Git reruns the config parsing mechanism upon
noticing the first URL-conditional include in order to find all remote
URLs, and these remote URLs are then used to determine if that first and
all subsequent includes are executed. Remote URLs are not allowed to be
configued in any URL-conditionally-included file.

In commit 8b09a900a1 ("merge-ort: restart merge with cached renames to
reduce process entry cost", 2021-07-16), we noted that in the merge-ort
steps of
collect_merge_info()
detect_and_process_renames()
process_entries()
that process_entries() was expensive, and we could often make it cheaper
by changing this to
collect_merge_info()
detect_and_process_renames()
<cache all the renames, and restart>
collect_merge_info()
detect_and_process_renames()
process_entries()
because the second collect_merge_info() would be cheaper (we could avoid
traversing into some directories), the second
detect_and_process_renames() would be free since we had already detected
all renames, and then process_entries() has far fewer entries to handle.
However, this was built on the assumption that the first
detect_and_process_renames() actually detected all potential renames.
If someone has merge.renameLimit set to some small value, that
assumption is violated which manifests later with the following message:
$ git -c merge.renameLimit=1 rebase upstream
...
git: merge-ort.c:546: clear_or_reinit_internal_opts: Assertion
`renames->cached_pairs_valid_side == 0' failed.
Turn off this cache-renames-and-restart whenever we cannot detect all
renames, and add a testcase that would have caught this problem.

"pull --rebase" internally uses the merge machinery when the other
history is a descendant of ours (i.e. perform fast-forward). This
came from [1], where the discussion was started from a feature
request to do so. It is a bit hard to read the rationale behind it
in the discussion, but it seems that it was an established fact for
everybody involved that does not even need to be mentioned that
fast-forwarding done with "rebase" was much undesirable than done
with "merge", and more importantly, the result left by "merge" is as
good as (or better than) that by "rebase".
Except for one thing. Because "git merge" does not (and should not)
honor rebase.autostash, "git pull" needs to read it and forward it
when we use "git merge" as a (hopefully better) substitute for "git
rebase" during the fast-forwarding. But we forgot to do so (we only
add "--[no-]autostash" to the "git merge" command when "git pull" itself
was invoked with "--[no-]autostash" command line option.
Make sure "git merge" is run with "--autostash" when
rebase.autostash is set and used to fast-forward the history on
behalf of "git rebase". Incidentally this change also takes care of
the case where
- "git pull --rebase" (without other command line options) is run
- "rebase.autostash" is not set
- The history fast-forwards
In such a case, "git merge" is run with an explicit "--no-autostash"
to prevent it from honoring merge.autostash configuration, which is
what we want. After all, we want the "git merge" to pretend as if
it is "git rebase" while being used for this purpose.

The C reimplementation of "add -p" fails to split the last hunk in a
file if hunk ends with an addition or deletion without any post context
line unless it is the last file to be processed.
To determine whether a hunk can be split a counter is incremented each
time a context line follows an insertion or deletion. If at the end of
the hunk the value of this counter is greater than one then the hunk
can be split into that number of smaller hunks. If the last hunk in a
file ends with an insertion or deletion then there is no following
context line and the counter will not be incremented. This case is
already handled at the end of the loop where counter is incremented if
the last hunk ended with an insertion or deletion. Unfortunately there
is no similar check between files (likely because the perl version
only ever parses one diff at a time). Fix this by checking if the last
hunk ended with an insertion or deletion when we see the diff header
of a new file and extend the existing regression test.

When merging a signed tag, fmt_merge_msg_sigs() is responsible for
populating the body of the merge message with the names of the signed
tags, their signatures, and the validity of those signatures.
In 02769437e1 (ssh signing: use sigc struct to pass payload,
2021-12-09), check_signature() was taught to pass the object payload via
the sigc struct instead of passing the payload buffer separately.
In effect, 02769437e1 causes buf, and sigc.payload to point at the same
region in memory. This causes a problem for fmt_tag_signature(), which
wants to read from this location, since it is freed beforehand by
signature_check_clear() (which frees it via sigc's `payload` member).
That makes the subsequent use in fmt_tag_signature() a use-after-free.
As a result, merge messages did not contain the body of any signed tags.
Luckily, they tend not to contain garbage, either, since the result of
strstr()-ing the object buffer in fmt_tag_signature() is guarded:
const char *tag_body = strstr(buf, "\n\n");
if (tag_body) {
tag_body += 2;
strbuf_add(tagbuf, tag_body, buf + len - tag_body);
}
Unfortunately, the tests in t6200 did not catch this at the time because
they do not search for the body of signed tags in fmt-merge-msg's
output.
Resolve this by waiting to call signature_check_clear() until after its
contents can be safely discarded. Harden ourselves against any future
regressions in this area by making sure we can find signed tag messages
in the output of fmt-merge-msg, too.
