Jeff King 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).

Adam Dinwoodie a1e03535db t4129: fix setfacl-related permissions failure
When running this test in Cygwin, it's necessary to remove the inherited
access control lists from the Git working directory in order for later
permissions tests to work as expected.

As such, fix an error in the test script so that the ACLs are set for
the working directory, not a nonexistent subdirectory.

Derrick Stolee 6c62f01552 for-each-repo: do nothing on empty config
'git for-each-repo --config=X' should return success without calling any
subcommands when the config key 'X' has no value. The current
implementation instead segfaults.

A user could run into this issue if they used 'git maintenance start' to
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.

Philippe Blain 80f5a16798 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).

Matheus Tavares ea8bbf2a4e 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.

Taylor Blau cc2d43be2b 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.

The logic added to check for negative pathspec match by c0192df630
(refspec: add support for negative refspecs, 2020-09-30) looks at
refspec->src assuming it is never NULL, however when
remote.origin.push is set to ":", then refspec->src is NULL,
causing a segfault within strcmp.

Tell git to handle matching refspec by adding the needle to the
set of positively matched refspecs, since matching ":" refspecs
match anything as src.

Add test for matching refspec pushes fetch-negative-refspec
both individually and in combination with a negative refspec.

When we insert our "BEGIN" and "END" markers into the cron table, it's

identify this region in the cron table. Let's add a test to make sure
that these markers don't ever change.

Martin Ågren 66dc0a3625 gc: fix handling of crontab magic markers
On `git maintenance start`, we add a few entries to the user's cron
table. We wrap our entries using two magic markers, "# BEGIN GIT
MAINTENANCE SCHEDULE" and "# END GIT MAINTENANCE SCHEDULE". At a later
`git maintenance stop`, we will go through the table and remove these
lines. Or rather, we will remove the "BEGIN" marker, the "END" marker
and everything between them.

Alas, we have a bug in how we detect the "END" marker: we don't. As we
loop through all the lines of the crontab, if we are in the "old
region", i.e., the region we're aiming to remove, we make an early
`continue` and don't get as far as checking for the "END" marker. Thus,
once we've seen our "BEGIN", we remove everything until the end of the
file.

Rewrite the logic for identifying these markers. There are four cases
that are mutually exclusive: The current line starts a region or it ends
it, or it's firmly within the region, or it's outside of it (and should
be printed).

time when `git init` would use that name for the initial branch.

Even if that time has not arrived, we can complete the transition by
making the test script independent of the default branch name. This also
allows us to drop the `PREPARE_FOR_MAIN_BRANCH` prereq from one test
case.

Johannes Schindelin ec9779bcd8 t3200: finish transitioning to the initial branch name main
In 56300ff356 (t3200: prepare for `main` being shorter than `master`,
2020-10-23) and in 66713e84e7 (tests: prepare aligned mentions of the
default branch name, 2020-10-23), we started to prepare t3200 for a new
world where `git init` uses the branch name `main` for the initial
branch.

We do not even have to wait for that new world: we can easily ensure
that that branch name is used, independent of the exact name `git init`
will give the initial branch, so let's do that.

This also lets us remove the `PREPARE_FOR_MAIN_BRANCH` prereq from three
test cases in that script.

Johannes Schindelin 35a16dbe32 t1400: use main as initial branch name
In 3224b0f0bb (t1400: prepare for `main` being default branch name,
2020-10-23), we prepared t1400 for a time when the default initial
branch name would be `main`.

However, there is no need to wait that long: let's adjust the test
script to stop relying on a specific initial branch name by setting it
explicitly. This allows us to drop the `PREPARE_FOR_MAIN_BRANCH` prereq
from two test cases.

Junio C Hamano 50f0439490 diff: correct interaction between --exit-code and -I<pattern>
Just like "git diff -w --exit-code" should exit with 0 when ignoring
whitespace differences results in no changes shown, if ignoring
certain changes with "git diff -I<pattern> --exit-code" result in an
empty patch, we should exit with 0.

The test suite did not cover the interaction between "--exit-code"
and "-w"; add one while adding a new test for "--exit-code" + "-I".

Eric Sunshine f4698738f9 t/perf: fix test_export() failure with BSD sed
test_perf() runs each test in its own subshell which makes it difficult
to persist variables between tests. test_export() addresses this
shortcoming by grabbing the values of specified variables after a test
runs but before the subshell exits, and writes those values to a file
which is loaded into the environment of subsequent tests.

To grab the values to be persisted, test_export() pipes the output of
the shell's builtin `set` command through `sed` which plucks them out
using a regular expression along the lines of `s/^(var1|var2)/.../p`.
Unfortunately, though, this use of alternation is not portable. For
instance, BSD-lineage `sed` (including macOS `sed`) does not support it
in the default "basic regular expression" mode (BRE). It may be possible
to enable "extended regular expression" mode (ERE) in some cases with
`sed -E`, however, `-E` is neither portable nor part of POSIX.

Fortunately, alternation is unnecessary in this case and can easily be
avoided, so replace it with a series of simple expressions such as
`s/^var1/.../p;s/^var2/.../p`.

While at it, tighten the expressions so they match the variable names
exactly rather than matching prefixes (i.e. use `s/^var1=/.../p`).

If the requirements of test_export() become more complex in the future,
then an alternative would be to replace `sed` with `perl` which supports
alternation on all platforms, however, the simple elimination of
alternation via multiple `sed` expressions suffices for the present.

Johannes Schindelin 675704c74d init: provide useful advice about init.defaultBranch
To give ample warning for users wishing to override Git's the fall-back
for an unconfigured `init.defaultBranch` (in case we decide to change it
in a future Git version), let's introduce some advice that is shown upon
`git init` when that value is not set.

Note: two test cases in Git's test suite want to verify that the
`stderr` output of `git init` is empty. It is now necessary to suppress
the advice, we now do that via the `init.defaultBranch` setting. While
not strictly necessary, we also set this to `false` in
`test_create_repo()`.
