In t0000, we run several fake "sub-test" suites to verify the behavior
of the test suite. But because we don't clear the parent environment
completely, the sub-tests can be fooled by variables meant for the
parent. For example:
GIT_SKIP_TESTS=t1234 ./t0000-basic.sh
fails when a sub-test expects its fake t1234 to actually run. This
particular pattern is unlikely in practice; we're running a single
script, and there is no t1234 in the real test suite anyway (not yet, at
least). A more real-world example is:
GIT_SKIP_TESTS=t[^0]* make test
to run only the t0* tests.
The fix is conceptually simple: we should clear the GIT_SKIP_TESTS
variable when running the sub-tests, because its contents (if any) will
be meant for the main test suite. This is easy to do centrally in our
sub-test helper.
But there's a catch: some of our tests do set GIT_SKIP_TESTS
intentionally to test the feature. We need to allow them to continue to
set it, but clear it for all the other tests. And the sub-test helper
can't tell if the GIT_SKIP_TESTS it sees is from a test or not. We can
handle this by adding a new option to the helper to let callers specify
the skip list.
I considered adding a more general "--eval" option to let callers set up
the env for the sub-test however they like. That would cover this case
and possible future ones. But the quoting gets awkward for the callers
(since we're now 2 layers deep in evals!), so I went with the simpler
more specific solution.

The shell+perl "[de]packetize()" helper functions were added in
4414a150025 (t/lib-git-daemon: add network-protocol helpers,
2018-01-24), and around the same time we added the "pkt-line" helper
in 74e70029615 (test-pkt-line: introduce a packet-line test helper,
2018-03-14).
For some reason it seems we've mostly used the shell+perl version
instead of the helper since then. There were discussions around
88124ab2636 (test-lib-functions: make packetize() more efficient,
2020-03-27) and cacae4329fa (test-lib-functions: simplify packetize()
stdin code, 2020-03-29) to improve them and make them more efficient.
There was one good reason to do so, we needed an equivalent of
"test-tool pkt-line pack", but that command wasn't capable of handling
input with "\n" (a feature) or "\0" (just because it happens to be
printf-based under the hood).
Let's add a "pkt-line-raw" helper for that, and expose is at a
packetize_raw() to go with the existing packetize() on the shell
level, this gives us the smallest amount of change to the tests
themselves.

The default reason stored in the lock file, "added with --lock",
is unlikely to be what the user would have given in a separate
`git worktree lock` command. Allowing `--reason` to be specified
along with `--lock` when adding a working tree gives the user control
over the reason for locking without needing a second command.

Commit 88473c8bae ("load_ref_decorations(): avoid parsing non-tag
objects", 2021-06-22) introduced a shortcut to `add_ref_decoration()`:
Rather than calling `parse_object()`, we go for `oid_object_info()` and
then `lookup_object_by_type()` using the type just discovered. As
detailed in the commit message, this provides a significant time saving.
Unfortunately, it also changes the behavior: We lose all annotated tags
from the decoration.
The reason this happens is in the loop where we try to peel the tags, we
won't necessarily have parsed that first object. If we haven't, its
`tagged` field will be NULL, so we won't actually add a decoration for
the pointed-to object.
Make sure to parse the tag object at the top of the peeling loop. This
effectively restores the pre-88473c8bae parsing -- but only of tags,
allowing us to keep most of the possible speedup from 88473c8bae.
On my big ~220k ref test case (where it's mostly non-tags), the
timings [using "git log -1 --decorate"] are:
- before either patch: 2.945s
- with my broken patch: 0.707s
- with [this patch]: 0.788s
The simplest way to do this is to just conditionally parse before the
loop:
if (obj->type == OBJ_TAG)
parse_object(&obj->oid);
But we can observe that our tag-peeling loop needs to peel already, to
examine recursive tags-of-tags. So instead of introducing a new call to
parse_object(), we can simply move the parsing higher in the loop:
instead of parsing the new object before we loop, parse each tag object
before we look at its "tagged" field.
This has another beneficial side effect: if a tag points at a commit (or
other non-tag type), we do not bother to parse the commit at all now.
And we know it is a commit without calling oid_object_info(), because
parsing the surrounding tag object will have created the correct in-core
object based on the "type" field of the tag.
Our test coverage for --decorate was obviously not good, since we missed
this quite-basic regression. The new tests covers an annotated tag
(showing the fix), but also that we correctly show annotations for
lightweight tags and double-annotated tag-of-tags.

In general, we encourage users to use plumbing commands, like git
rev-list, over porcelain commands, like git log, when scripting.
However, git rev-list has one glaring problem that prevents it from
being used in certain cases: when --pretty is used with a custom format,
it always prints out a line containing "commit" and the object ID. This
makes it unsuitable for many scripting needs, and forces users to use
git log instead.
While we can't change this behavior for backwards compatibility, we can
add an option to suppress this behavior, so let's do so, and call it
"--no-commit-header". Additionally, add the corresponding positive
option to switch it back on.
Note that this option doesn't affect the built-in formats, only custom
formats. This is exactly the same behavior as users already have from
git log and is what most users will be used to.

This saves 8K per `struct object_directory', meaning it saves
around 800MB in my case involving 100K alternates (half or more
of those alternates are unlikely to hold loose objects).
This is implemented in two parts: a generic, allocation-free
`cbtree' and the `oidtree' wrapper on top of it. The latter
provides allocation using alloc_state as a memory pool to
improve locality and reduce free(3) overhead.
Unlike oid-array, the crit-bit tree does not require sorting.
Performance is bound by the key length, for oidtree that is
fixed at sizeof(struct object_id). There's no need to have
256 oidtrees to mitigate the O(n log n) overhead like we did
with oid-array.
Being a prefix trie, it is natively suited for expanding short
object IDs via prefix-limited iteration in
`find_short_object_filename'.
On my busy workstation, p4205 performance seems to be roughly
unchanged (+/-8%). Startup with 100K total alternates with no
loose objects seems around 10-20% faster on a hot cache.
(800MB in memory savings means more memory for the kernel FS
cache).
The generic cbtree implementation does impose some extra
overhead for oidtree in that it uses memcmp(3) on
"struct object_id" so it wastes cycles comparing 12 extra bytes
on SHA-1 repositories. I've not yet explored reducing this
overhead, but I expect there are many places in our code base
where we'd want to investigate this.
