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.

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:
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).

its own "am I detached?" detection.

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 28438e84e04 (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 d4919bb288e (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.
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 76f9e569adb (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 b4c8eb024af (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.

git_connect_git(): forbid newlines in host and path
When we connect to a git:// server, we send an initial request that
looks something like:
002dgit-upload-pack repo.git\0host=example.com
If the repo path contains a newline, then it's included literally, and
we get:
002egit-upload-pack repo
.git\0host=example.com
This works fine if you really do have a newline in your repository name;
the server side uses the pktline framing to parse the string, not
newlines. However, there are many _other_ protocols in the wild that do
parse on newlines, such as HTTP. So a carefully constructed git:// URL
can actually turn into a valid HTTP request. For example:
0050git-upload-pack /
GET / HTTP/1.1
Host:localhost
host=localhost:1234
on the wire. Again, this isn't a problem for a real Git server, but it
does mean that feeding a malicious URL to Git (e.g., through a
submodule) can cause it to make unexpected cross-protocol requests.
Since repository names with newlines are presumably quite rare (and
indeed, we already disallow them in git-over-http), let's just disallow
them over this protocol.
Hostnames could likewise inject a newline, but this is unlikely a
problem in practice; we'd try resolving the hostname with a newline in
it, which wouldn't work. Still, it doesn't hurt to err on the side of
caution there, since we would not expect them to work in the first
place.
The ssh and local code paths are unaffected by this patch. In both cases
we're trying to run upload-pack via a shell, and will quote the newline
so that it makes it intact. An attacker can point an ssh url at an
arbitrary port, of course, but unless there's an actual ssh server
there, we'd never get as far as sending our shell command anyway. We
_could_ similarly restrict newlines in those protocols out of caution,
but there seems little benefit to doing so.
The new test here is run alongside the git-daemon tests, which cover the
same protocol, but it shouldn't actually contact the daemon at all. In
theory we could make the test more robust by setting up an actual
repository with a newline in it (so that our clone would succeed if our
new check didn't kick in). But a repo directory with newline in it is
likely not portable across all filesystems. Likewise, we could check
git-daemon's log that it was not contacted at all, but we do not
currently record the log (and anyway, it would make the test racy with
the daemon's log write). We'll just check the client-side stderr to make
sure we hit the expected code path.

mergetool--lib: fix '--tool-help' to correctly show available tools
Commit 83bbf9b92e (mergetool--lib: improve support for vimdiff-style tool
variants, 2020-07-29) introduced a regression in the output of `git mergetool
--tool-help` and `git difftool --tool-help` [1].
In function 'show_tool_names' in git-mergetool--lib.sh, we loop over the
supported mergetools and their variants and accumulate them in the variable
'variants', separating them with a literal '\n'.
The code then uses 'echo $variants' to turn these '\n' into newlines, but this
behaviour is not portable, it just happens to work in some shells, like
dash(1)'s 'echo' builtin.
For shells in which 'echo' does not turn '\n' into newlines, the end
result is that the only tools that are shown are the existing variants
(except the last variant alphabetically), since the variants are
separated by actual newlines in '$variants' because of the several
'echo' calls in mergetools/{bc,vimdiff}::list_tool_variants.
Fix this bug by embedding an actual line feed into `variants` in
show_tool_names(). While at it, replace `sort | uniq` by `sort -u`.
To prevent future regressions, add a simple test that checks that a few
known tools are correctly shown (let's avoid counting the total number
of tools to lessen the maintenance burden when new tools are added or if
'--tool-help' learns additional logic, like hiding tools depending on
the current platform).

t4129: don't fail if setgid is set in the test directory
The last test of t4129 creates a directory and expects its setgid bit
(g+s) to be off. But this makes the test fail when the parent directory
has the bit set, as setgid's state is inherited by newly created
subdirectories.
One way to solve this problem is to allow the presence of this bit when
comparing the return of `test_modebits` with the expected value. But
then we may have the same problem in the future when other tests start
using `test_modebits` on directories (currently t4129 is the only one)
and forget about setgid. Instead, let's make the helper function more
robust with respect to the state of the setgid bit in the test directory
by removing this bit from the returning value. There should be no
problem with existing callers as no one currently expects this bit to be
on.
Note that the sticky bit (+t) and the setuid bit (u+s) are not
inherited, so we don't have to worry about those.

Note that `do_write_index()` takes a tempfile and that when we call it,

p7519: allow running without watchman prereq
p7519 measures the performance of the fsmonitor code. To do this, it
uses the installed copy of Watchman. If Watchman isn't installed, a noop
integration script is installed in its place.
When in the latter mode, it is expected that the script should not write
a "last update token": in fact, it doesn't write anything at all since
the script is blank.
Commit 33226af42b (t/perf/fsmonitor: improve error message if typoing
hook name, 2020-10-26) made sure that running 'git update-index
--fsmonitor' did not write anything to stderr, but this is not the case
when using the empty Watchman script, since Git will complain that:
$ which watchman
watchman not found
$ cat .git/hooks/fsmonitor-empty
$ git -c core.fsmonitor=.git/hooks/fsmonitor-empty update-index --fsmonitor
warning: Empty last update token.
Prior to 33226af42b, the output wasn't checked at all, which allowed
this noop mode to work. But, 33226af42b breaks p7519 when running it
without a 'watchman(1)' on your system.
Handle this by only checking that the stderr is empty only when running
with a real watchman executable. Otherwise, assert that the error
message is the expected one when running in the noop mode.

t6016: move to lib-log-graph.sh framework
t6016 manually reconstructs git log --graph output by using the reported
commit hashes from `git rev-parse`. Each tag is converted into an

file, which is in turn compared to the actual output.
The expected output is difficult to read and write, because, e.g.,
each line of output must be prefaced with echo, quoted, and properly
escaped. Additionally, the test is sensitive to trailing whitespace,
which may potentially be removed from graph log output in the future.
In order to reduce duplication, ease troubleshooting of failed tests by
improving readability, and ease the addition of more tests to this file,
port the operations to `lib-log-graph.sh`, which is already used in
several other tests, e.g., t4215. Give all merges a simple commit
message, and use a common `check_graph` macro taking a heredoc of the
