It's a single line that is used in a single place, and the variable has
the same name as the function.

If fetch_remote is NULL (i.e. the branch remote is invalid), then it
can't possibly be same as remote, which can't be NULL.
The check is redundant, and so is the extra variable.
Also, fix the Yoda condition: we want to check if remote is the same as
the branch remote, not the other way around.

We want all the cases that don't do anything with a branch first, and
then the rest. That way we will be able to get the branch and die if
there's a problem in the parent function, instead of inside the function
of each mode.

Now that the code has been simplified and it's clear what it's
actually doing, update the documentation to reflect that.
Namely; the simple mode only barfs when working on a centralized
workflow, and there's no configured upstream branch with the same name.

There's a safety check to make sure branch->refname isn't different
from branch->merge[0]->src, otherwise we die().
Therefore we always push to branch->refname.

Simply move the code around and remove dead code. In particular the
'!same_remote' conditional is a no-op since that part of the code is the
same_remote leg of the conditional beforehand.

In order to avoid doing unnecessary things and simplify it in further
patches. In particular moving the additional name safety out of
setup_push_upstream() and into setup_push_simple() and thus making both
more straightforward.
The code is copied exactly as-is; no functional changes.

The typical case is what git was designed for: distributed remotes.
It's only the atypical case--fetching and pushing to the same
remote--that we need to keep an eye on.

In 56c6910028a (fsmonitor: change last update timestamp on the
index_state to opaque token, 2020-01-07), we forgot to adjust
`discard_index()` to release the "last-update" token: it is no longer a
64-bit number, but a free-form string that has been allocated.

In 56c6910028a (fsmonitor: change last update timestamp on the
index_state to opaque token, 2020-01-07), we forgot to adjust the part
of `unpack_trees()` that copies the FSMonitor "last-update" information
that we copy from the source index to the result index since 679f2f9fdd2
(unpack-trees: skip stat on fsmonitor-valid files, 2019-11-20).
Since the "last-update" information is no longer a 64-bit number, but a
free-form string that has been allocated, we need to duplicate it rather
than just copying it.
This is important because there _are_ cases when `unpack_trees()` will
perform a oneway merge that implicitly calls `refresh_fsmonitor()`
(which will allocate that "last-update" token). This happens _after_
that token was copied into the result index. However, we _then_ call
`check_updates()` on that index, which will _also_ call
`refresh_fsmonitor()`, accessing the "last-update" string, which by now
would be released already.
In the instance that lead to this patch, this caused a segmentation
fault during a lengthy, complicated rebase involving the todo command
`reset` that (crucially) had to updated many files. Unfortunately, it
seems very hard to trigger that crash, therefore this patch is not
accompanied by a regression test.

This patch fixes a bug where git-bisect doesn't handle receiving
annotated tags as "git bisect good <tag>", etc. It's a regression in
27257bc466 (bisect--helper: reimplement `bisect_state` & `bisect_head`
shell functions in C, 2020-10-15).
The original shell code called:
sha=$(git rev-parse --verify "$rev^{commit}") ||
die "$(eval_gettext "Bad rev input: \$rev")"
which will peel the input to a commit (or complain if that's not
possible). But the C code just calls get_oid(), which will yield the oid
of the tag.
The fix is to peel to a commit. The error message here is a little
non-idiomatic for Git (since it starts with a capital). I've mostly left
it, as it matches the other converted messages (like the "Bad rev input"
we print when get_oid() fails), though I did add an indication that it
was the peeling that was the problem. It might be worth taking a pass
through this converted code to modernize some of the error messages.
Note also that the test does a bare "grep" (not i18ngrep) on the
expected "X is the first bad commit" output message. This matches the
rest of the test script.

4f37d45706 ("clone: respect remote unborn HEAD", 2021-02-05) introduces
a new feature (if the remote has an unborn HEAD, e.g. when the remote
repository is empty, use it as the name of the branch) that only works
in protocol v2, but did not ensure that one of its tests always uses
protocol v2, and thus that test would fail if
GIT_TEST_PROTOCOL_VERSION=0 (or 1) is used. Therefore, add "-c
protocol.version=2" to the appropriate test.
(The rest of the tests from that commit have "-c protocol.version=2"
already added.)

Allow BLOCK_GROWTH_SIZE to be used like an integer literal by removing
the trailing semicolon from its definition. Also wrap the expression in
parentheses, to allow it to be used with operators without leading to
unexpected results. It doesn't matter for the current use site, but
make it follow standard macro rules anyway to avoid future surprises.

23119ffb4e (block-sha1: put expanded macro parameters in parentheses,
2012-07-22) added a trailing semicolon to the definition of SHA_MIX
without explanation. It doesn't matter with the current code, but make
sure to avoid potential surprises by removing it again.
This allows the macro to be used almost like a function: Users can
combine it with operators of their choice, but still must not pass an
expression with side-effects as a parameter, as it would be evaluated
multiple times.

query_result can be be an empty strbuf (STRBUF_INIT) - in that case
trying to read 3 bytes triggers a buffer overflow read (as
query_result.buf = '\0').
Therefore we need to check query_result's length before trying to read 3
bytes.
This overflow was introduced in:
940b94f35c (fsmonitor: log invocation of FSMonitor hook to trace2, 2021-02-03)
It was found when running the test-suite against ASAN, and can be most
easily reproduced with the following command:
make GIT_TEST_OPTS="-v" DEFAULT_TEST_TARGET="t7519-status-fsmonitor.sh" \
