The test case added by 9466e3809d ("blame: enable funcname blaming with

f08b6c553d p5303: avoid sed GNU-ism
Using "1~5" isn't portable. Nobody seems to have noticed, since perhaps
people don't tend to run the perf suite on more exotic platforms. Still,
it's better to set a good example.

We can use:

  perl -ne 'print if $. % 5 == 1'

instead. But we can further observe that perl does a good job of the
other parts of this pipeline, and fold the whole thing together.

2b0e14f640 ci: do not cancel all jobs of a matrix if one fails
The CI/PR GitHub Actions workflow uses the 'matrix' strategy for the
"windows-test", "vs-test", "regular" and "dockerized" jobs. The default
behaviour of GitHub Actions is to cancel all in-progress jobs in a
matrix if one of the job of the matrix fails [1].

This is not ideal as a failure early in a job, like during installation of
the build/test dependencies on a specific platform, leads to the
cancellation of all other jobs in the matrix.

Set the 'fail-fast' variable to 'false' for all four matrix jobs in the
workflow.

We run "git pull" against "$cask_repo"; clarify that we are
expecting not to have any of our own modifications and running "git
pull" to merely update, by passing "--ff-only" on the command line.

Also, the "brew cask install" command line triggers an error message
that says:

    Error: Calling brew cask install is disabled! Use brew install
    [--cask] instead.

In addition, "brew install caskroom/cask/perforce" step triggers an
error that says:

Attempt to see if blindly following the suggestion in these error
messages gets us into a better shape.

c9e3a4e76d patch-ids: handle duplicate hashmap entries
This fixes a bug introduced in dfb7a1b4d0 (patch-ids: stop using a
hand-rolled hashmap implementation, 2016-07-29) in which

  git rev-list --cherry-pick A...B

will fail to suppress commits reachable from A even if a commit with
matching patch-id appears in B.

Around the time of that commit, the algorithm for "--cherry-pick" looked
something like this:

  0. Traverse all of the commits, marking them as being on the left or
     right side of the symmetric difference.

  1. Iterate over the left-hand commits, inserting a patch-id struct for
     each into a hashmap, and pointing commit->util to the patch-id
     struct.

  2. Iterate over the right-hand commits, checking which are present in
     the hashmap. If so, we exclude the commit from the output _and_ we
     mark the patch-id as "seen".

  3. Iterate again over the left-hand commits, checking whether
     commit->util->seen is set; if so, exclude them from the output.

At the end, we'll have eliminated commits from both sides that have a
matching patch-id on the other side. But there's a subtle assumption
here: for any given patch-id, we must have exactly one struct
representing it. If two commits from A both have the same patch-id and
we allow duplicates in the hashmap, then we run into a problem:

  a. In step 1, we insert two patch-id structs into the hashmap.

  b. In step 2, our lookups will find only one of these structs, so only
     one "seen" flag is marked.

  c. In step 3, one of the commits in A will have its commit->util->seen
     set, but the other will not. We'll erroneously output the latter.

Prior to dfb7a1b4d0, our hashmap did not allow duplicates. Afterwards,
it used hashmap_add(), which explicitly does allow duplicates.

At that point, the solution would have been easy: when we are about to
add a duplicate, skip doing so and return the existing entry which
matches. But it gets more complicated.

In 683f17ec44 (patch-ids: replace the seen indicator with a commit
pointer, 2016-07-29), our step 3 goes away entirely. Instead, in step 2,
when the right-hand side finds a matching patch_id from the left-hand
side, we can directly mark the left-hand patch_id->commit to be omitted.
Solving that would be easy, too; there's a one-to-many relationship of
patch-ids to commits, so we just need to keep a list.

But there's more. Commit b3dfeebb92 (rebase: avoid computing unnecessary
patch IDs, 2016-07-29) built on that by lazily computing the full
patch-ids. So we don't even know when adding to the hashmap whether two
commits truly have the same id. We'd have to tentatively assign them a
list, and then possibly split them apart (possibly into N new structs)
at the moment we compute the real patch-ids. This could work, but it's
complicated and error-prone.

Instead, let's accept that we may store duplicates, and teach the lookup
side to be more clever. Rather than asking for a single matching
patch-id, it will need to iterate over all matching patch-ids. This does
mean examining every entry in a single hash bucket, but the worst-case
for a hash lookup was already doing that.

We'll keep the hashmap details out of the caller by providing a simple
iteration interface. We can retain the simple has_commit_patch_id()
interface for the other callers, but we'll simplify its return value
into an integer, rather than returning the patch_id struct. That way
they won't be tempted to look at the "commit" field of the return value
without iterating.

9371c0e9dd gettext.c: remove/reword a mostly-useless comment
Mostly remove the comment I added 5e9637c629 (i18n: add

So having more than 1/4 of the file taken up by a digression about a
glibc bug that mostly doesn't happen to anyone anymore is just a
needless distraction. Shorten the comment to make a brief mention of

The table describing the porcelain format in git-status(1) is helpful,

acaabcf391 t5516: loosen "not our ref" error check
Commit 014ade7484 (upload-pack: send ERR packet for non-tip objects,
2019-04-13) added a test that greps the output of a failed fetch to make
sure that upload-pack sent us the ERR packet we expected. But checking
this is racy; despite the argument in that commit, the client may still
be sending a "done" line after the server exits, causing it to die() on
a failed write() and never see the ERR packet at all.

This fails quite rarely on Linux, but more often on macOS. However, it
can be triggered reliably with:

	diff --git a/fetch-pack.c b/fetch-pack.c
	index 876f90c759..cf40de9092 100644
	--- a/fetch-pack.c
	+++ b/fetch-pack.c
	@@ -489,6 +489,7 @@ static int find_common(struct fetch_negotiator *negotiator,
	 done:
	 	trace2_region_leave("fetch-pack", "negotiation_v0_v1", the_repository);
	 	if (!got_ready || !no_done) {
	+		sleep(1);
	 		packet_buf_write(&req_buf, "done\n");
	 		send_request(args, fd[1], &req_buf);
	 	}

This is a real user-visible race that it would be nice to fix, but it's
tricky to do so: the client would have to speculatively try to read an
ERR packet after hitting a write() error. And at least for this error,
it's specific to v0 (since v2 does not enforce reachability at all).

So let's loosen the test to avoid annoying racy failures. If we
eventually do the read-after-failed-write thing, we can tighten it. And
if not, v0 will grow increasingly obsolete as servers support v2, so the
utility of this test will decrease over time anyway.

Note that we can still check stderr to make sure upload-pack bailed for
the reason we expected. It writes a similar message to stderr, and
because the server side is just another process connected by pipes,
we'll reliably see it. This would not be the case for git://, or for
ssh servers that do not relay stderr (e.g., GitHub's custom endpoint
does not).

initialize their cron schedule using 'git for-each-repo
--config=maintenance.repo ...' but then using 'git maintenance
unregister' to remove the config option. (Note: 'git maintenance stop'
would remove the config _and_ remove the cron schedule.)

Add a simple test to ensure this works. Use 'git help --no-such-option'
as the potential subcommand to ensure that we will hit a failure if the
subcommand is ever run.

0454986e78 SubmittingPatches: tighten wording on "sign-off" procedure
The text says "if you can certify DCO then you add a Signed-off-by
trailer".  But it does not say anything about people who cannot or
do not want to certify.  A natural reading may be that if you do not
certify, you must not add the trailer, but it shouldn't hurt to be
overly explicit.

4045f659bd branch: show "HEAD detached" first under reverse sort
Change the output of the likes of "git branch -l --sort=-objectsize"
to show the "(HEAD detached at <hash>)" message at the start of the
output. Before the compare_detached_head() function added in a
preceding commit we'd emit this output as an emergent effect.

It doesn't make any sense to consider the objectsize, type or other
non-attribute of the "(HEAD detached at <hash>)" message for the
purposes of sorting. Let's always emit it at the top instead. The only
reason it was sorted in the first place is because we're injecting it
into the ref-filter machinery so builtin/branch.c doesn't need to do
its own "am I detached?" detection.

2708ce62d2 branch: sort detached HEAD based on a flag
Change the ref-filter sorting of detached HEAD to check the
FILTER_REFS_DETACHED_HEAD flag, instead of relying on the ref
description filled-in by get_head_description() to start with "(",
which in turn we expect to ASCII-sort before any other reference.

For context, we'd like the detached line to appear first at the start
of "git branch -l", e.g.:

    $ git branch -l
    * (HEAD detached at <hash>)
      master

This doesn't change that, but improves on a fix made in
28438e84e0 (ref-filter: sort detached HEAD lines firstly, 2019-06-18)
and gives the Chinese translation the ability to use its preferred
punctuation marks again.

In Chinese the fullwidth versions of punctuation like "()" are
typically written as (U+FF08 fullwidth left parenthesis), (U+FF09
fullwidth right parenthesis) instead[1]. This form is used in both
po/zh_{CN,TW}.po in most cases where "()" is translated in a string.

Aside from that improvement to the Chinese translation, it also just
makes for cleaner code that we mark any special cases in the ref_array
we're sorting with flags and make the sort function aware of them,
instead of piggy-backing on the general-case of strcmp() doing the
right thing.

As seen in the amended tests this made reverse sorting a bit more
consistent. Before this we'd sometimes sort this message in the
middle, now it's consistently at the beginning or end, depending on
whether we're doing a normal or reverse sort. Having it at the end
doesn't make much sense either, but at least it behaves consistently
now. A follow-up commit will make this behavior under reverse sorting
even better.

I'm removing the "TRANSLATORS" comments that were in the old code
while I'm at it. Those were added in d4919bb288 (ref-filter: move
get_head_description() from branch.c, 2017-01-10). I think it's
obvious from context, string and translation memory in typical
translation tools that these are the same or similar string.

7c269a7b16 ref-filter: move ref_sorting flags to a bitfield
Change the reverse/ignore_case/version sort flags in the ref_sorting
struct into a bitfield. Having three of them was already a bit
unwieldy, but it would be even more so if another flag needed a
function like ref_sorting_icase_all() introduced in
76f9e569ad (ref-filter: apply --ignore-case to all sorting keys,
2020-05-03).

A follow-up change will introduce such a flag, so let's move this over
to a bitfield. Instead of using the usual '#define' pattern I'm using
the "enum" pattern from builtin/rebase.c's b4c8eb024a (builtin
rebase: support --quiet, 2018-09-04).

Perhaps there's a more idiomatic way of doing the "for each in list
amend mask" pattern than this "mask/on" variable combo. This function
doesn't allow us to e.g. do any arbitrary changes to the bitfield for
multiple flags, but I think in this case that's fine. The common case
is that we're calling this with a list of one.

d0947483a3 ref-filter: move "cmp_fn" assignment into "else if" arm
Further amend code changed in 7c5045fc18 (ref-filter: apply fallback
refname sort only after all user sorts, 2020-05-03) to move an
assignment only used in the "else if" arm to happen there. Before that
commit the cmp_fn would be used outside of it.

We could also just skip the "cmp_fn" assignment and use
strcasecmp/strcmp directly in a ternary statement here, but this is
probably more readable.
