* ds/bitmap-lookup-remove-tracing:
pack-bitmap: remove trace2 region from hot path
|
|
The trace2 region around the call to lazy_bitmap_for_commit() in
bitmap_for_commit() was added in 28cd730680d (pack-bitmap: prepare to
read lookup table extension, 2022-08-14). While adding trace2 regions is
typically helpful for tracking performance, this method is called
possibly thousands of times as a commit walk explores commit history
looking for a matching bitmap. When trace2 output is enabled, this
region is emitted many times and performance is throttled by that
output.
For now, remove these regions entirely.
This is a critical path, and it would be valuable to measure that the
time spent in bitmap_for_commit() does not increase when using the
commit lookup table. The best way to do that would be to use a mechanism
that sums the time spent in a region and reports a single value at the
end of the process. This technique was introduced but not merged by [1]
so maybe this example presents some justification to revisit that
approach.
[1] https://lore.kernel.org/git/pull.1099.v2.git.1640720202.gitgitgadget@gmail.com/
To help with the 'git blame' output in this region, add a comment that
warns against adding a trace2 region. Delete a test from t5310 that used
that trace output to check that this lookup optimization was activated.
To create this kind of test again in the future, the stopwatch traces
mentioned earlier could be used as a signal that we activated this code
path.

Fix manpage generation.
* ma/scalar-to-main-fix:
cmd-list.perl: fix identifying man sections
|
|
We attribute each documentation text file to a man section by finding a
line in the file that looks like "gitfoo(<digit>)". Commit cc75e556a9
("scalar: add to 'git help -a' command list", 2022-09-02) updated this
logic to look not only for "gitfoo" but also "scalarfoo". In doing so,
it forgot to account for the fact that after the updated regex has found
a match, the man section is no longer to be found in `$1` but now lives
in `$2`.
This makes our git(1) manpage look as follows:
Main porcelain commands
git-add(git)
Add file contents to the index.
[...]
gitk(git)
The Git repository browser.
scalar(scalar)
A tool for managing large Git repositories.
Restore the man sections by not capturing the (git|scalar) part of the
match into `$1`.
As noted by Ævar [1], we could even match any "foo" rather than just
"gitfoo" and "scalarfoo", but that's a larger change. For now, just fix
the regression in cc75e556a9.

Fix uninitialized memory access in a recent fix-up that is already
in -rc1.
* jk/list-objects-filter-cleanup:
list-objects-filter: initialize sub-filter structs
|
|
Since commit c54980ab83 (list-objects-filter: convert filter_spec to a
strbuf, 2022-09-11), building with SANITIZE=undefined triggers an error
in t5616.
The problem is that we end up with a strbuf that has been
zero-initialized instead of via STRBUF_INIT. Feeding that strbuf to
strbuf_addbuf() in list_objects_filter_copy() means we will call memcpy
like:
memcpy(some_actual_buffer, NULL, 0);
This works on most systems because we're copying zero bytes, but it is
technically undefined behavior to ever pass NULL to memcpy.
Even though c54980ab83 is where the bug manifests, that is only because
we switched away from a string_list, which is OK with being
zero-initialized (though it may cause other problems by not duplicating
the strings, it happened to be OK in this instance).
The actual bug is caused by the commit before that, 2a01bdedf8
(list-objects-filter: add and use initializers, 2022-09-11). There we
consistently initialize the top-level filter structs, but we forgot the
dynamically allocated ones we stick in filter_options->sub when creating
combined filters.
Note that we need to fix two spots here: where we parse a "combine:"
filter, but also where we transform from a single-filter into a combined
one after seeing multiple "--filter" options. In the second spot, we'll
do some minor refactoring to avoid repeating our very-long array index.

The 't/test-results' directory and its contents are by-products of the
test process, so 'make clean' should remove them, but, alas, this has
been broken since fee65b194d (t/Makefile: don't remove test-results in
"clean-except-prove-cache", 2022-07-28).
The 'clean' target in 't/Makefile' was not directly responsible for
removing the 'test-results' directory, but relied on its dependency
'clean-except-prove-cache' to do that [1]. ee65b194d broke this,
because it only removed the 'rm -r test-results' command from the
'clean-except-prove-cache' target instead of moving it to the 'clean'
target, resulting in stray 't/test-results' directories.
Add that missing cleanup command to 't/Makefile', and to all
sub-Makefiles touched by that commit as well.

Like most builtins, 'version' is documented in a corresponding
'Documentation/git-version.txt' and can be invoked with 'git version'.
However, the 'check-docs' Makefile target showed that it was "removed but
documented: git-version." This was cause by the fact that it is not built as
a standalone 'git-version' executable, therefore appearing "removed" to
'check-docs'.
Without a precedent for documented builtins that aren't built into an
executable *or* any clear reason why a standalone 'git-version' shouldn't
exist, the 'check-docs' error appears to correctly identify an issue. To
correct that mismatch, add 'git-version' to the 'BUILT_INS' list in the root
Makefile (indicating that the 'cmd_version()' function appears in a file
that is *not* 'builtin/version.c'). Additionally, to avoid the "no link"
message in 'check-docs', list 'git-version' as an "ancilliaryinterrogator"
(like 'git help') in 'command-list.txt'.

Refactor usage of the 'd_type' property of 'struct dirent' in 'diagnose.c'
to instead utilize the compatibility macro 'DTYPE()'. On systems where
'd_type' is not present in 'struct dirent', this macro will always return
'DT_UNKNOWN'. In that case, instead fall back on using the 'stat.st_mode' to
determine whether the dirent points to a dir, file, or link.
Additionally, add a test to 't0092-diagnose.sh' to verify that files (e.g.,
loose objects) are counted properly.
Note that the new function 'get_dtype()' is based on 'resolve_dtype()' in
'dir.c' (which itself was refactored from a prior 'get_dtype()' in
ad6f2157f9 (dir: restructure in a way to avoid passing around a struct
dirent, 2020-01-16)), but differs in that it is meant for use on arbitrary
files, such as those inside the '.git' dir. Because of this, it does not
search the index for a matching entry to derive the 'd_type'.

The speed of the merged_iter_pqueue_add() can be improved by using a
pointer to the pq_entry struct, which is 96 bytes. Since the pq_entry
param is worked directly on the stack and does not currently have a
pointer to it, the merged_iter_pqueue_add() function is slightly
slower.
References to pq_entry in reftable have typically included pointers,
such as both of the params for pq_less().
Since we are working with pointers in the pq_entry param, as keenly
pointed out, the pq_entry param has also been made into a const since
the contents of the pq_entry param are copied and not manipulated.

On Cygwin, when failing to spawn a process using start_command, Git
outputs the same error as on Linux systems, rather than using the
GIT_WINDOWS_NATIVE-specific error output. The WINDOWS test prerequisite
is set in both Cygwin and native Windows environments, which means it's
not appropriate to use to anticipate the error output from
start_command. Instead, use the MINGW test prerequisite, which is only
set for Git in native Windows environments, and not for Cygwin.
