Use a ref_sorting_release() in branch.c to free the memory from the
ref_sorting_options(). This plugs the final in-tree memory leak of
that API.
In the preceding commit the "sorting" variable was left in the
cmd_branch() scope, even though that wasn't needed anymore. Move it to
the "else if (list)" scope instead. We can also move the "struct
string_list" only used for that branch to be declared in that block
That "struct ref_sorting" does not need to be "static" (and isn't
re-used). The "ref_sorting_options()" will return a valid one, we
don't need to make it "static" to have it zero'd out. That it was
static was another artifact of the pre-image of the preceding commit.

When a transport helper pushes via send-pack, it passes --helper-status
to get a machine-readable status back for each ref. The previous commit
taught the send-pack code to hand back "error expecting report" if the
server did not send us the proper ref-status. And that's enough to cause
us to recognize that an error occurred for the ref and print something
sensible in our final status table.
But we do interpret these messages on the remote-helper side to turn
them back into REF_STATUS_* enum values. Recognizing this token to turn
it back into REF_STATUS_EXPECTING_REPORT has two advantages:
1. We now print exactly the same message in the human-readable (and
machine-readable --porcelain) output for this situation whether the
transport went through a helper (e.g., http) or not (e.g., ssh).
2. If any code in the helper really cares about distinguishing
EXPECT_REPORT from more generic error conditions, it could now do
so. I didn't find any, so this is mostly future-proofing.
So this is mostly cosmetic for now, but it seems like the
least-surprising thing for the transport-helper code to be doing.

When pushing to a server which erroneously omits the final ref-status
report, the client side should complain about the refs for which we
didn't receive the status (because we can't just assume they were
updated). This works over most transports like ssh, but for http we'll
print a very misleading "Everything up-to-date".
It works for ssh because send-pack internally sets the status of each
ref to REF_STATUS_EXPECTING_REPORT, and then if the server doesn't tell
us about a particular ref, it will stay at that value. When we print the
final status table, we'll see that we're still on EXPECTING_REPORT and
complain then.
But for http, we go through remote-curl, which invokes send-pack with
"--stateless-rpc --helper-status". The latter option causes send-pack to
return a machine-readable list of ref statuses to the remote helper. But
ever since its inception in de1a2fdd38 (Smart push over HTTP: client
side, 2009-10-30), the send-pack code has simply omitted mention of any
ref which ended up in EXPECTING_REPORT.
In the remote helper, we then take the absence of any status report
from send-pack to mean that the ref was not even something we tried to
send, and thus it prints "Everything up-to-date". Fortunately it does
detect the eventual non-zero exit from send-pack, and propagates that in
its own non-zero exit code. So at least a careful script invoking "git
push" would notice the failure. But sending the misleading message on
stderr is certainly confusing for humans (not to mention the
machine-readable "push --porcelain" output, though again, any careful
script should be checking the exit code from push, too).
Nobody seems to have noticed because the server in this instance has to
be misbehaving: it has promised to support the ref-status capability
(otherwise the client will not set EXPECTING_REPORT at all), but didn't
send us any. If the connection were simply cut, then send-pack would
complain about getting EOF while trying to read the status. But if the
server actually sends a flush packet (i.e., saying "now you have all of
the ref statuses" without actually sending any), then the client ends up
in this confused situation.
The fix is simple: we should return an error message from "send-pack
--helper-status", just like we would for any other error per-ref error
condition (in the test I included, the server simply omits all ref
status responses, but a more insidious version of this would skip only
some of them).

builtin/gc.c has two ways of checking if multi-pack-index is enabled:
- git_config_get_bool() in incremental_repack_auto_condition()
- the_repository->settings.core_multi_pack_index in
maintenance_task_incremental_repack()
The two implementations have existed since the incremental-repack task
was introduced in e841a79a13 (maintenance: add incremental-repack auto
condition, 2020-09-25). These two values can diverge because
prepare_repo_settings() enables the feature in the_repository->settings
by default.
In the case where core.multiPackIndex is not set in the config, the auto
condition would fail, causing the incremental-repack task to not be
run. Because we always want to consider the default values, we should
always use the_repository->settings.

Apply similar treatment as in the last commit to the MIDX `repack`
operation.
Signed-off-by: Taylor Blau <me@ttaylorr.com>
Signed-off-by: Junio C Hamano <gitster@pobox.com>
Before a new MIDX can be written, expire_midx_packs() first loads the
existing MIDX, figures out which packs can be expired, and then writes a
new MIDX based on that information.
In order to load the existing MIDX, it uses load_multi_pack_index(),
which mmaps the multi-pack-index file, but does not store the resulting
`struct multi_pack_index *` in the object store.
write_midx_internal() also needs to open the existing MIDX, and it does
so by iterating the results of get_multi_pack_index(), so that it reuses
the same pointer held by the object store. But before it can move the
new MIDX into place, it close_object_store() to munmap() the
multi-pack-index file to accommodate platforms like Windows which don't
allow overwriting files which are memory mapped.
That's where things get weird. Since expire_midx_packs has its own
*separate* memory mapped copy of the MIDX, the MIDX file is still memory
mapped! Interestingly, this doesn't seem to cause a problem in our
tests. (I believe that this has much more to do with my own lack of
familiarity with Windows than it does a lack of coverage in our tests).
In any case, we can side-step the whole issue by teaching
expire_midx_packs() to use the `struct multi_pack_index` pointer it
found via the object store instead of maintain its own copy. That way,
when write_midx_internal() calls `close_object_store()`, we know that
there are no memory mapped copies of the MIDX laying around.
A couple of other small notes about this patch:
- As far as I can tell, passing `local == 1` to the call to
load_multi_pack_index() was an error, since object_dir could be an
alternate. But it doesn't matter, since even though we write
`m->local = 1`, we never read that field back later on.
- Setting `m = NULL` after write_midx_internal() was likely to prevent
a double-free back from when that function took a `struct
multi_pack_index *` that it called close_midx() on itself. We can
rely on write_midx_internal() to call that for us now.
Finally, this enforces the same "the value of --object-dir must be the
local object store, or an alternate" rule from f57a739691 (midx: avoid
opening multiple MIDXs when writing, 2021-09-01) to the `expire`
sub-command, too.

Follow-up the change in 459b8d22e5 (tests: do not borrow from COPYING
and README from the real source, 2015-02-15) by not shipping a full
copy of older versions of the top-level "COPYING" and "README" files.
The tests that use them just need the small blurb at the top of
"COPYING" as test data, or mock data that's dissimilar. Let's provide
that with a "COPYING_test_data" function instead.
We're not replacing this with some other generic test
data (e.g. "lorum ipsum") because these tests require test file header
to be the old "COPYING" file. See e.g. "t4003-diff-rename-1.sh" which
changes the file, and then does full "test_cmp" comparisons on the
resulting "git diff" output.
This change only changes tests that used the "lib-diff.sh" library,
but splits up what they need into a new "lib-diff-data.sh". A
subsequent commit will change related tests that were missed in
459b8d22e5.
For the test in "t4008-diff-break-rewrite.sh" the "README" file can go
away in favor of echoing the line "some dissimilar content" to a file
in the one test that needed it.
The point of that test is to start with files "A" and "B", and then
have A be more similar to the state of "B" than to its old version (by
copying over the content from the "COPYING" file). Just comparing the
pre-image of "some dissimilar content" and later a munged version of
the "COPYING" output serves that purpose.
While we're at it get rid of a stray "echo $tree" debugging line added
in 15d061b435 ([PATCH] Fix the way diffcore-rename records unremoved
source., 2005-05-27), and stop calling "hash-object" to get the hash
of an object we've just added to the index. We can instead extract
that information from the index itself with "rev-parse".

Extend the code added in d6538246d3 (commit-graph: not compatible
with replace objects, 2018-08-20) which ignored replace objects in the
"write" command to ignore it in the "verify" command too.
We can just move this assignment to the cmd_commit_graph(), it
dispatches to "write" and "verify", and we're unlikely to ever get a
sub-command that would like to consider replace refs.
This will make tests added in eddc1f556c (mktag tests: test
update-ref and reachable fsck, 2021-06-17) pass in combination with
the "GIT_TEST_COMMIT_GRAPH" mode added in 859fdc0c3c (commit-graph:
define GIT_TEST_COMMIT_GRAPH, 2018-08-29), except that mode is
currently broken (but is being fixed concurrently). See the discussion
starting at [1].

In 135a712375 (commit-graph: add --split option to builtin,
2019-06-18) this function was copy/pasted to the split commit-graph
tests, as in the preceding commit we need to fix this to use
&&-chaining, so it won't be hiding errors.
Unlike its sister function in "t5318-commit-graph.sh", which we got
lucky with, this one was hiding a real test failure. A tests added in
c523035cbd (commit-graph: allow cross-alternate chains, 2019-06-18)
has never worked as intended. Unlike most other graph_git_behavior
uses in this file it clones the repository into a sub-directory, so
we'll need to refer to "commits/6" as "origin/commits/6".
It's not easy to simply move the "graph_git_behavior" to the test
above it, since it itself spawns a "test_expect_success". Let's
instead add support to "graph_git_behavior()" and
"graph_git_two_modes()" to pass a "-C" argument to git.
We also need to add a "test -d fork" here, because otherwise we'll
fail on e.g.:
GIT_SKIP_TESTS=t5324.13 ./t5324-split-commit-graph.sh

The graph_git_two_modes() helper added in 177722b344 (commit:
integrate commit graph with commit parsing, 2018-04-10) didn't
&&-chain its "git commit-graph" invocations, which as can be seen with
SANITIZE=leak will happily mark tests as passing if both of these
commands die, since test_cmp() will be comparing two empty files.

Try to re-chmod the trash directory on startup if we fail to "rm -rf"
it. This fixes problems where the test leaves the trash directory
behind in a bad permission state for whatever reason.
This fixes an interaction between [1] where t0004-unwritable.sh was
made to use "test_when_finished" for cleanup, and [2] which added the
"--immediate" mode. If a test in this file failed when running with
"--immediate" we wouldn't run the "test_when_finished" block, which
re-chmods the ".git/objects" directory (see [1]).
This can be demonstrated as e.g. (output snipped for less verbosity):
$ ./t0004-unwritable.sh --run=3 --immediate
ok 1 # skip setup (--run)
ok 2 # skip write-tree should notice unwritable repository (--run)
not ok 3 - commit should notice unwritable repository
[...]
$ ./t0004-unwritable.sh --run=3 --immediate
rm: cannot remove '[...]/trash directory.t0004-unwritable/.git/objects/info': Permission denied
FATAL: Cannot prepare test area
[...]
Instead of some version of reverting [1] let's make the test-lib.sh
resilient to this edge-case, it will happen due to [1], but also
e.g. if the relevant "test-lib.sh" process is kill -9'd during the
test run. We should try harder to recover in this case. If we fail to
remove the test directory let's retry after (re-)chmod-ing it.
This doesn't need to be guarded by something that's equivalent to
"POSIXPERM" since if we don't support "chmod" we were about to fail
anyway.
Let's also discard any error output from (a possibly nonexisting)
"chmod", we'll fail on the subsequent "rm -rf" anyway, likewise for
the first "rm -rf" invocation, we don't want to get the "cannot
remove" output if we can get around it with the "chmod", but we do
want any error output from the second "rm -rf", in case that doesn't
fix the issue.
The lack of &&-chaining between the "chmod" and "rm -rf" is
intentional, if we fail the first "rm -rf", can't chmod, but then
succeed the second time around that's what we were hoping for. We just
want to nuke the directory, not carry forward every possible error
code or error message.

Improve the "GIT_TEST_PASSING_SANITIZE_LEAK=true" test mode added in
956d2e4639 (tests: add a test mode for SANITIZE=leak, run it in CI,
2021-09-23) to use a TAP "Bail out!" message when exiting. This will
cause the test run to exit immediately under a TAP consumer like
"prove(1)".
See 614fe01521 (test-lib: bail out when "-v" used under "prove",
2016-10-22) for the initial introduction of "Bail out!" to the
--verbose being amended here.
Before this compiling with "SANITIZE=" and running the tests with
"prove(1)" would cause all the tests to be run to the end (output
trimmed for fewer columns):
$ GIT_TEST_PASSING_SANITIZE_LEAK=true make
rm -f -r 'test-results'
*** prove ***
t0000-basic.sh ......... Dubious, test returned 1 (wstat 256, 0x100)
No subtests run
t0001-init.sh .......... Dubious, test returned 1 (wstat 256, 0x100)
No subtests run
[...output where we list every single t[0-9]*.sh file as failing snipped]
Whereas now we'll fail early, like this ("->" line wrapping added):
$ GIT_TEST_PASSING_SANITIZE_LEAK=true make
[...]
t0000-basic.sh ..................................... Bailout called. Further testing stopped:
-> GIT_TEST_PASSING_SANITIZE_LEAK=true has no effect except when compiled with SANITIZE=leak
FAILED--Further testing stopped: GIT_TEST_PASSING_SANITIZE_LEAK=true has no effect except
-> when compiled with SANITIZE=leak
make: *** [Makefile:53: prove] Error 1
This change also adds a red color to the "Bailout called" line, as
we're now using "say_color error". That improves existing output in
the case of e.g.:
$ prove -j8 t[0-9]*.sh :: -v
Bailout called. Further testing stopped: verbose mode forbidden under TAP harness; try --verbose-log
FAILED--Further testing stopped: verbose mode forbidden under TAP harness; try --verbose-log
We don't need to have a "Bail out! " prefix when we're not running
under a TAP consumer (i.e. if test -n "$HARNESS_ACTIVE"), but let's
not make the output conditional on that. Showing it under e.g.:
$ GIT_TEST_PASSING_SANITIZE_LEAK=true ./t0095-bloom.sh
Bail out! GIT_TEST_PASSING_SANITIZE_LEAK=true has no effect except when compiled with SANITIZE=leak
Doesn't harm anything, and I don't think the (small) complexity of
only adding this if we're under "$HARNESS_ACTIVE" is worth it.
