As noted by Junio:
Back when "git am" was written, it was not considered a bug that the
"git am --resolved" option did not offer the user a chance to update
the log message to match the adjustment of the code the user made,
but honestly, I'd have to say that it is a bug in "git am" in that
over time it wasn't adjusted to the new world order where we
encourage users to describe what they did when the automation
hiccuped by opening an editor. These days, even when automation
worked well (e.g. a clean auto-merge with "git merge"), we open an
editor. The world has changed, and so should the expectations.
Junio also suggested providing a workaround such as allowing --no-edit
together with git rebase --continue, but that should probably be done in
a patch after the git-2.26.0 release. For now, just document the known
difference in the Behavioral Differences section.

In commit e98c4269c8 ("rebase (interactive-backend): fix handling of
commits that become empty", 2020-02-15), the merge backend was changed
to drop commits that did not start empty but became so after being
applied (because their changes were a subset of what was already
upstream). This new code path did not need to go through the process of
creating a commit, since we were dropping the commit instead.
Unfortunately, this also means we bypassed the clearing of the
CHERRY_PICK_HEAD and MERGE_MSG files, which if there were no further
commits to cherry-pick would mean that the rebase would end but assume
there was still an operation in progress. Ensure that we clear such
state files when we decide to drop the commit.

Both "git ls-remote -h" and "git grep -h" give short usage help,
like any other Git subcommand, but it is not unreasonable to expect
that the former would behave the same as "git ls-remote --head"
(there is no other sensible behaviour for the latter). The
documentation has been updated in an attempt to clarify this.

Often novice Git users forget to say "pull --rebase" and end up with an
unnecessary merge from upstream. What they usually want is either "pull
--rebase" in the simpler cases, or "pull --ff-only" to update the copy
of main integration branches, and rebase their work separately. The
pull.rebase configuration variable exists to help them in the simpler
cases, but there is no mechanism to make these users aware of it.
Issue a warning message when no --[no-]rebase option from the command
line and no pull.rebase configuration variable is given. This will
inconvenience those who never want to "pull --rebase", who haven't had
to do anything special, but the cost of the inconvenience is paid only
once per user, which should be a reasonable cost to help a number of new
users.

Ever since 862e730ec1 (commit-slab: introduce slabname##_peek()
function, 2015-05-14) the slabname##_peek() function is documented as:
This function is similar to indegree_at(), but it will return NULL
until a call to indegree_at() was made for the commit.
This, however, is usually not the case. If indegree_at() allocates
memory, then it will do so not only for the single commit it got as
parameter, but it will allocate a whole new, ~512kB slab. Later on,
if any other commit's 'index' field happens to point into an already
allocated slab, then indegree_peek() for such a commit will return a
valid non-NULL pointer, pointing to a zero-initialized location in the
slab, even if no indegree_at() call has been made for that commit yet.
Update slabname##_peek()'s documentation to clarify this.

Returning a shared buffer invites very subtle bugs due to reentrancy or
multi-threading, as demonstrated by the previous patch.
There was an unfinished effort to abolish this [1].
Let's finally rid of `real_path()`, using `strbuf_realpath()` instead.
This patch uses a local `strbuf` for most places where `real_path()` was
previously called.
However, two places return the value of `real_path()` to the caller. For
them, a `static` local `strbuf` was added, effectively pushing the
problem one level higher:
read_gitfile_gently()
get_superproject_working_tree()

Python2 reached end of life, and we have been preparing our Python
scripts to work with Python3. 'git p4', the main in-tree user of
Python, has just received a number of compatibility updates. Our
other notable Python script 'contrib/svn-fe/svnrdump_sim.py' is only
used in 't9020-remote-svn.sh', and is apparently already compatible
with both Python2 and 3.
Our CI jobs currently only use Python2. We want to make sure that
these Python scripts do indeed work with Python3, and we also want to
make sure that these scripts keep working with Python2 as well, for
the sake of some older LTS/Enterprise setups.
Therefore, pick two jobs and use Python3 there, while leaving other
jobs to still stick to Python2 for now.

Recently we inadvertently added a few instances of using 0-width

the warning in our developer builds, but not for general public.
The new instances have been corrected, and the warning has been

"git am --short-current-patch" is a way to show the piece of e-mail

We grep for "File exists" in stderr of the failing `git sparse-checkout`
to make sure that it failed for the right reason. We expect the string
to show up there since we call `strerror(errno)` in
`unable_to_lock_message()` in lockfile.c.
On the NonStop platform, this fails because the error string is "File
already exists", which doesn't match our grepping.
See 9042140097 ("test-dir-iterator: do not assume errno values",
2019-07-30) for a somewhat similar fix. There, we patched a test helper,
which meant we had access to `errno` and could investigate it better in
the test helper instead of just outputting the numerical value and
evaluating it in the test script. The current situation is different,
since (short of modifying the lockfile machinery, e.g., to be more
verbose) we don't have more than the output from `strerror()` available.
Except we do: We prefix `strerror(errno)` with `_("Unable to create
'%s.lock': ")`. Let's grep for that part instead. It verifies that we
were indeed unable to create the lock file. (If that fails for some
other reason than the file existing, we really really should expect
other tests to fail as well.)
An alternative fix would be to loosen the expression a bit and grep for
"File.* exists" instead. There would be no guarantee that some other
implementation couldn't come up with another error string, That is, that
could be the first move in an endless game of whack-a-mole. Of course,
it could also take us from "99" to "100" percent of the platforms and
we'd never have this problem again. But since we have another way of
addressing this, let's not even try the "loosen it up a bit" strategy.

`real_path()` returns result from a shared buffer, inviting subtle
reentrance bugs. One of these bugs occur when invoked this way:
set_git_dir(real_path(git_dir))
In this case, `real_path()` has reentrance:
real_path
read_gitfile_gently
repo_set_gitdir
setup_git_env
set_git_dir_1
set_git_dir
Later, `set_git_dir()` uses its now-dead parameter:
!is_absolute_path(path)
Fix this by using a dedicated `strbuf` to hold `strbuf_realpath()`.

Remove the stash.useBuiltin setting which was added as an escape hatch
to disable the builtin version of stash first released with Git 2.22.
Carrying the legacy version is a maintenance burden, and has in fact
become out of date failing a test since the 2.23 release, without
anyone noticing until now. So users would be getting a hint to fall
back to a potentially buggy version of the tool.
We used to shell out to git config to get the useBuiltin configuration
to avoid changing any global state before spawning legacy-stash.
However that is no longer necessary, so just use the 'git_config'
function to get the setting instead.
Similar to what we've done in d03ebd411c ("rebase: remove the
rebase.useBuiltin setting", 2019-03-18), where we remove the
corresponding setting for rebase, we leave the documentation in place,
so people can refer back to it when searching for it online, and so we
can refer to it in the commit message.

Git supports performing connections to HTTPS proxies, but we don't
support doing mutual authentication with them (through TLS).
Add the necessary options to be able to send a client certificate to
the HTTPS proxy.
A client certificate can provide an alternative way of authentication
instead of using 'ProxyAuthorization' or other more common methods of
authentication. Libcurl supports this functionality already, so changes
are somewhat minimal. The feature is guarded by the first available
libcurl version that supports these options.
4 configuration options are added and documented, cert, key, cert
password protected and CA info. The CA info should be used to specify a
different CA path to validate the HTTPS proxy cert.
