am: fix incorrect exit status on am fail to abort
t4151: add a few am --abort tests
git-am.txt: clarify --abort behavior
"git update-ref --stdin" failed to flush its output as needed,
which potentially led the conversation to a deadlock.
* ps/update-ref-batch-flush:
t1400: avoid SIGPIPE race condition on fifo
update-ref: fix streaming of status updates
The "mode" word is useless in a call to open(2) that does not
create a new file. Such a call in the files backend of the ref
subsystem has been cleaned up.
* rs/no-mode-to-open-when-appending:
refs/files-backend: remove unused open mode parameter
The run-command API has been updated so that the callers can easily
ask the file descriptors open for packfiles to be closed immediately
before spawning commands that may trigger auto-gc.
* js/run-command-close-packs:
Close object store closer to spawning child processes
run_auto_maintenance(): implicitly close the object store
run-command: offer to close the object store before running

Various mergy operations have been prepared to work efficiently
with the sparse index.

t1092: add cherry-pick, rebase tests
merge-ort: expand only for out-of-cone conflicts
merge: make sparse-aware with ORT
diff: ignore sparse paths in diffstat
In cone mode, the sparse-index code path learned to remove ignored
files (like build artifacts) outside the sparse cone, allowing the
entire directory outside the sparse cone to be removed, which is
especially useful when the sparse patterns change.
* ds/sparse-index-ignored-files:
sparse-checkout: clear tracked sparse dirs
sparse-index: add SPARSE_INDEX_MEMORY_ONLY flag

The order in which various files that make up a single (conceptual)
packfile has been reevaluated and straightened up. This matters in
correctness, as an incomplete set of files must not be shown to a
running Git.
* tb/pack-finalize-ordering:
pack-objects: rename .idx files into place after .bitmap files
pack-write: split up finish_tmp_packfile() function

The code to show progress indicator in a few code paths did not
cover between 0-100%, which has been corrected.
* ab/progress-users-adjust-counters:
entry: show finer-grained counter in "Filtering content" progress line
commit-graph: fix bogus counter in "Scanning merged commits" progress line
"git diff --submodule=diff" showed failure from run_command() when
trying to run diff inside a submodule, when the user manually
removes the submodule directory.

The code to make "git grep" recurse into submodules has been
updated to migrate away from the "add submodule's object store as
an alternate object store" mechanism (which is suboptimal).
* jt/grep-wo-submodule-odb-as-alternate:
t7814: show lack of alternate ODB-adding
submodule-config: pass repo upon blob config read
grep: add repository to OID grep sources
grep: allocate subrepos on heap
grep: read submodule entry with explicit repo
grep: typesafe versions of grep_source_init
grep: use submodule-ODB-as-alternate lazy-addition
submodule: lazily add submodule ODBs as alternates
The reachability bitmap file used to be generated only for a single
pack, but now we've learned to generate bitmaps for history that

Optimize code that handles large number of refs in the "git fetch"
code path.

fetch: avoid second connectivity check if we already have all objects
fetch: merge fetching and consuming refs
fetch: refactor fetch refs to be more extendable
fetch-pack: optimize loading of refs via commit graph
connected: refactor iterator to return next object ID directly
fetch: avoid unpacking headers in object existence check
fetch: speed up lookup of want refs via commit-graph
The code that optionally creates the *.rev reverse index file has
been optimized to avoid needless computation when it is not writing
the file out.
* ab/reverse-midx-optim:
pack-write: skip *.rev work when not writing *.rev
"make INSTALL_STRIP=-s install" allows the installation step to use
"install -s" to strip the binaries as they get installed.
* bs/install-strip:
make: add INSTALL_STRIP option variable
Teach "test_pause" and "debug" helpers to allow using the HOME and
TERM environment variables the user usually uses.

The "git apply -3" code path learned not to bother the lower level
merge machinery when the three-way merge can be trivially resolved
without the content level merge.
* jc/trivial-threeway-binary-merge:
apply: resolve trivial merge without hitting ll-merge with "--3way"
t1400.190 sometimes fails or even hangs because of the way it uses
fifos. Our goal is to interactively read and write lines from
update-ref, so we have two fifos, in and out. We open a descriptor
connected to "in" and redirect output to that, so that update-ref does
not see EOF as it would if we opened and closed it for each "echo" call.
But we don't do the same for the output. This leads to a race where our
"read response <out" has not yet opened the fifo, but update-ref tries
to write to it and gets SIGPIPE. This can result in the test failing, or
worse, hanging as we wait forever for somebody to write to the pipe.
This is the same proble we fixed in 4783e7ea83 (t0008: avoid SIGPIPE
race condition on fifo, 2013-07-12), and we can fix it the same way, by
opening a second long-running descriptor.
Before this patch, running:
./t1400-update-ref.sh --run=1,190 --stress
failed or hung within a few dozen iterations. After it, I ran it for
several hundred without problems.

When the launchctl_boot_plist() function was added in
a16eb6b1ff (maintenance: skip bootout/bootstrap when plist is
registered, 2021-08-24), an unused call to launchctl_get_uid() was
added along with it. That call appears to have been copy/pasted from
launchctl_boot_plist().
Since we can remove that, we can also get rid of the "result"
variable, whose only purpose was allow for the free() between its
assignment and the return. That pattern also appears to have been
copy/pasted from launchctl_boot_plist().
As the patch shows the returned value from launchctl_get_uid() wasn't
used at all in this function. The launchctl_get_uid() function itself
just calls xstrfmt() and getuid(), neither of which have any subtle
global side-effects, so this removal is safe.

In be5d88e112 (test-tool run-command: learn to run (parts of) the
testsuite, 2019-10-04) an init pattern was added that would use
TESTSUITE_INIT, but then promptly memset() everything back to 0. We'd
then set the "dup" on the two string lists.
Our setting of "next" to "-1" thus did nothing, we'd reset it to "0"
before using it. Let's set it to "0" instead, and trust the
"STRING_LIST_INIT_DUP" to set "strdup_strings" appropriately for us.
Note that while we compile this code, there's no in-tree user for the
"testsuite" target being modified here anymore, see the discussion at
and around <nycvar.QRO.7.76.6.2109091323150.59@tvgsbejvaqbjf.bet>[1].

Remove untracked files that are unwanted after they are done being used.
While the set of cases in this patch is certainly far from
comprehensive, it was motivated by some work to see what the fallout
would be if we were to make the removal of untracked files as a side
effect of other commands into an error. Some cases were a bit more
involved than the testcase changes included in this patch, but the ones
included here represent the simple cases. While this patch is not that
important since we are not changing the behavior of those other commands
into an error in the near term, I thought these changes were useful
anyway as an explicit documentation of the intent that these untracked
files are no longer useful.

We converted argv_array (which later became strvec) to use size_t in
819f0e76b1 (argv-array: use size_t for count and alloc, 2020-07-28) in
order to avoid the possibility of integer overflow. But later, commit
d70a9eb611 (strvec: rename struct fields, 2020-07-28) accidentally
converted these back to ints!
Those two commits were part of the same patch series. I'm pretty sure
what happened is that they were originally written in the opposite order
and then cleaned up and re-ordered during an interactive rebase. And
when resolving the inevitable conflict, I mistakenly took the "rename"
patch completely, accidentally dropping the type change.
We can correct it now; better late than never.

Store the object ID of broken pack entries in an oidset instead of
keeping only their hashes in an unsorted array. The resulting code is
shorter and easier to read. It also handles the (hopefully) very rare
case of having a high number of bad objects better.
