There are some commands permit the user whether to provide options
first before args, or the reverse order. For example:
git push --dry-run <remote> <ref>
And:
git push <remote> <ref> --dry-run
Both of them is supported, but some commands do not, for instance:
git ls-remote --heads <remote>
And:
git ls-remote <remote> --heads
If <remote> only has one ref and it's name is "refs/heads/--heads", you
will get the same result, otherwise will not.This is because the former
in the second example will parse "--heads" as an "option" which means
to limit to only "refs/heads" when listing the remote references, the
latter treat "--heads" as an argument which means to filter the result
list with the given pattern.
Therefore, we want to specify a bit more in "gitcli.txt" about the way
we recommend and help to resolve the ambiguity around some git command
usage. The related disscussions locate at [1].
By the way, there are some issues with lowercase letters in the document,
which have been modified together.

"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.

Fix a logic error in refs_resolve_ref_unsafe() introduced in a recent
series of mine to abstract the refs API away from errno. See
96f6623ada (Merge branch 'ab/refs-errno-cleanup', 2021-11-29)for that
series.
In that series introduction of "failure_errno" to
refs_resolve_ref_unsafe came in ef18119dec (refs API: add a version
of refs_resolve_ref_unsafe() with "errno", 2021-10-16). There we'd set
"errno = 0" immediately before refs_read_raw_ref(), and then set
"failure_errno" to "errno" if errno was non-zero afterwards.
Then in the next commit 8b72fea7e9 (refs API: make
refs_read_raw_ref() not set errno, 2021-10-16) we started expecting
"refs_read_raw_ref()" to set "failure_errno". It would do that if
refs_read_raw_ref() failed, but it wouldn't be the same errno.
So we might set the "errno" here to any arbitrary bad value, and end
up e.g. returning NULL when we meant to return the refname from
refs_resolve_ref_unsafe(), or the other way around. Instrumenting this
code will reveal cases where refs_read_raw_ref() will fail, and
"errno" and "failure_errno" will be set to different values.
In practice I haven't found a case where this scary bug changed
anything in practice. The reason for that is that we'll not care about
the actual value of "errno" here per-se, but only whether:
1. We have an errno
2. If it's one of ENOENT, EISDIR or ENOTDIR. See the adjacent code
added in a1c1d8170d (refs_resolve_ref_unsafe: handle d/f
conflicts for writes, 2017-10-06)
I.e. if we clobber "failure_errno" with "errno", but it happened to be
one of those three, and we'll clobber it with another one of the three
we were OK.
Perhaps there are cases where the difference ended up mattering, but I
haven't found them. Instrumenting the test suite to fail if "errno"
and "failure_errno" are different shows a lot of failures, checking if
they're different *and* one is but not the other is outside that list
of three "errno" values yields no failures.
But let's fix the obvious bug. We should just stop paying attention to
"errno" in refs_resolve_ref_unsafe(). In addition let's change the
partial resetting of "errno" in files_read_raw_ref() to happen just
before the "return", to ensure that any such bug will be more easily
spotted in the future.

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.

The documentation for the eol attribute states that it is "effectively
setting the text attribute". However, this implies that it forces the
text attribute to always be set, which has not been the case since
6523728499 ("convert: unify the "auto" handling of CRLF", 2016-06-28).
Let's avoid confusing users (and the present author when trying to
describe Git's behavior to others) by clearly documenting in which
cases the "eol" attribute has effect.
Specifically, the attribute always has an effect unless the file is
explicitly set as -text, or the file is set as text=auto and the file is
detected as binary.

Right now, it isn't clear what the behavior is when the eol attribute is
set in .gitattributes but the text attribute is not. Let's add some
tests to document this behavior in our code, which happens to be that
the behavior is as if we set the text attribute implicitly. This will
make sure we don't accidentally change the behavior, which somebody is
probably relying on, and serve as documentation to developers.

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.
