revision: set rev_input_given in handle_revision_arg()
Commit
7ba826290a (revision: add rev_input_given flag, 2017-08-02) added
a flag to rev_info to tell whether we got any revision arguments. As
explained there, this is necessary because some revision arguments may
not produce any pending traversal objects, but should still inhibit
default behaviors (e.g., a glob that matches nothing).
However, it only set the flag in the globbing code, but not for
revisions we get on the command-line or via stdin. This leads to two
problems:
- the command-line code keeps its own separate got_rev_arg flag; this
isn't wrong, but it's confusing and an extra maintenance burden
- even specifically-named rev arguments might end up not adding any
pending objects: if --ignore-missing is set, then specifying a
missing object is a noop rather than an error.
And that leads to some user-visible bugs:
- when deciding whether a default rev like "HEAD" should kick in, we
check both got_rev_arg and rev_input_given. That means that
"--ignore-missing $ZERO_OID" works on the command-line (where we set
got_rev_arg) but not on --stdin (where we don't)
- when rev-list decides whether it should complain that it wasn't
given a starting point, it relies on rev_input_given. So it can't
even get the command-line "--ignore-missing $ZERO_OID" right
Let's consistently set the flag if we got any revision argument. That
lets us clean up the redundant got_rev_arg, and fixes both of those bugs
(but note there are three new tests: we'll confirm the already working
git-log command-line case).
A few implementation notes:
- conceptually we want to set the flag whenever handle_revision_arg()
finds an actual revision arg ("handles" it, you might say). But it
covers a ton of cases with early returns. Rather than annotating
each one, we just wrap it and use its success exit-code to set the
flag in one spot.
- the new rev-list test is in t6018, which is titled to cover globs.
This isn't exactly a glob, but it made sense to stick it with the
other tests that handle the "even though we got a rev, we have no
pending objects" case, which are globs.
- the tests check for the oid of a missing object, which it's pretty
clear --ignore-missing should ignore. You can see the same behavior
with "--ignore-missing a-ref-that-does-not-exist", because
--ignore-missing treats them both the same. That's perhaps less
clearly correct, and we may want to change that in the future. But
the way the code and tests here are written, we'd continue to do the
right thing even if it does.

refs: remove lookup cache for reference-transaction hook
When adding the reference-transaction hook, there were concerns about
the performance impact it may have on setups which do not make use of
the new hook at all. After all, it gets executed every time a reftx is
prepared, committed or aborted, which linearly scales with the number of
reference-transactions created per session. And as there are code paths
like `git push` which create a new transaction for each reference to be
updated, this may translate to calling `find_hook()` quite a lot.
To address this concern, a cache was added with the intention to not
repeatedly do negative hook lookups. Turns out this cache caused a
regression, which was fixed via
e5256c82e5 (refs: fix interleaving hook
calls with reference-transaction hook, 2020-08-07). In the process of
discussing the fix, we realized that the cache doesn't really help even
in the negative-lookup case. While performance tests added to benchmark
this did show a slight improvement in the 1% range, this really doesn't
warrent having a cache. Furthermore, it's quite flaky, too. E.g. running
it twice in succession produces the following results:
Test master pks-reftx-hook-remove-cache
--------------------------------------------------------------------------
1400.2: update-ref 2.79(2.16+0.74) 2.73(2.12+0.71) -2.2%
1400.3: update-ref --stdin 0.22(0.08+0.14) 0.21(0.08+0.12) -4.5%
Test master pks-reftx-hook-remove-cache
--------------------------------------------------------------------------
1400.2: update-ref 2.70(2.09+0.72) 2.74(2.13+0.71) +1.5%
1400.3: update-ref --stdin 0.21(0.10+0.10) 0.21(0.08+0.13) +0.0%
One case notably absent from those benchmarks is a single executable
searching for the hook hundreds of times, which is exactly the case for
which the negative cache was added. p1400.2 will spawn a new update-ref
for each transaction and p1400.3 only has a single reference-transaction
for all reference updates. So this commit adds a third benchmark, which
performs an non-atomic push of a thousand references. This will create a
new reference transaction per reference. But even for this case, the
negative cache doesn't consistently improve performance:
Test master pks-reftx-hook-remove-cache
--------------------------------------------------------------------------
1400.4: nonatomic push 6.63(6.50+0.13) 6.81(6.67+0.14) +2.7%
1400.4: nonatomic push 6.35(6.21+0.14) 6.39(6.23+0.16) +0.6%
1400.4: nonatomic push 6.43(6.31+0.13) 6.42(6.28+0.15) -0.2%
So let's just remove the cache altogether to simplify the code.

checkout, restore: make pathspec recursive
The pathspec given to git checkout and git restore is used with both
tree_entry_interesting (via read_tree_recursive) and match_pathspec
(via ce_path_match). The latter effectively only supports recursive
matching regardless of the value of the pathspec flag "recursive",
which is unset here.
That causes different match results for pathspecs with wildcards, and
can lead checkout and restore in no-overlay mode to remove entries
instead of modifying them. Enable recursive matching for both checkout
and restore to make matching consistent.
Setting the flag in checkout_main() technically also affects git switch,

diff: index-line: respect --abbrev in object's name
A handful of Git's commands respect `--abbrev' for customizing length
of abbreviation of object names.
For diff-family, Git supports 2 different options for 2 different
purposes, `--full-index' for showing diff-patch object's name in full,
and `--abbrev' to customize the length of object names in diff-raw and
diff-tree header lines, without any options to customise the length of
object names in diff-patch format. When working with diff-patch format,
we only have two options, either full index, or default abbrev length.
Although, that behaviour is documented, it doesn't stop users from
trying to use `--abbrev' with the hope of customising diff-patch's
objects' name's abbreviation.
Let's allow the blob object names shown on the "index" line to be
abbreviated to arbitrary length given via the "--abbrev" option.
To preserve backward compatibility with old script that specify both

5302.3: index-pack 0 threads 256.28(253.41+2.79)
5302.4: index-pack 1 threads 257.03(254.03+2.91)
5302.5: index-pack 2 threads 149.39(268.34+3.06)
5302.6: index-pack 4 threads 94.96(294.10+3.23)
5302.7: index-pack 8 threads 68.12(339.26+3.89)
5302.8: index-pack 16 threads 70.90(655.03+7.21)
5302.9: index-pack default number of threads 116.91(290.05+3.21)
You can see that wall-clock times continue to improve dramatically up to
the number of cores, but bumping beyond that (into hyperthreading
territory) does not help (and in fact hurts a little).
Here's the same experiment on a machine with dual Xeon 6230's, totaling
40 cores (80 with hyperthreading):
5302.3: index-pack 0 threads 310.04(302.73+6.90)
5302.4: index-pack 1 threads 310.55(302.68+7.40)
5302.5: index-pack 2 threads 178.17(304.89+8.20)
5302.6: index-pack 5 threads 99.53(315.54+9.56)
5302.7: index-pack 10 threads 72.80(327.37+12.79)
5302.8: index-pack 20 threads 60.68(357.74+21.66)
5302.9: index-pack 40 threads 58.07(454.44+67.96)
5302.10: index-pack 80 threads 59.81(720.45+334.52)
5302.11: index-pack default number of threads 134.18(309.32+7.98)
The results are similar; things stop improving at 40 threads. Curiously,
going from 20 to 40 really doesn't help much, either (and increases CPU
time considerably). So that may represent an actual barrier to
parallelism, where we lose out due to context-switching and loss of
cache locality, but don't reap the wall-clock benefits due to contention
of our coarse-grained locks.
So what's a good default value? It's clear that the current cap of 3 is
too low; our default values are 42% and 57% slower than the best times
on each machine. The results on the 40-core machine imply that 20
threads is an actual barrier regardless of the number of cores, so we'll
take that as a maximum. We get the best results on these machines at
half of the online-cpus value. That's presumably a result of the
hyperthreading. That's common on multi-core Intel processors, but not
necessarily elsewhere. But if we take it as an assumption, we can
perform optimally on hyperthreaded machines and still do much better
than the status quo on other machines, as long as we never half below
the current value of 3.
So that's what this patch does.

p5302: count up to online-cpus for thread tests
When PERF_EXTRA is enabled, p5302 checks the performance of index-pack
with various numbers of threads. This can be useful for deciding what
the default should be (which is currently capped at 3 threads based on
the results of this script).
However, we only go up to 8 threads, and modern machines may have more.
Let's get the number of CPUs from test-tool, and test various numbers of
threads between one and that maximum.
Note that the current tests aren't all identical, as we have to set
GIT_FORCE_THREADS for the --threads=1 test (which measures the overhead
of starting a single worker thread versus the "0" case of using the main
thread). To keep the loop simple, we'll keep the "0" case out of it, and
set GIT_FORCE_THREADS=1 for all of the other cases (it's a noop for all
but the "1" case, since numbers higher than 1 would always need
threads).
Note also that we could skip running "test-tool" if PERF_EXTRA isn't
set. However, there's some small value in knowing the number of threads,
so that we can mark each test as skipped in the output.

p5302: disable thread-count parameter tests by default
The primary function of the perf suite is to detect regressions (or
improvements) between versions of Git. The only numbers we show a direct
comparison for are timings between the same test run on two different
versions.
However, it can sometimes be used to collect other information. For
instance, p5302 runs the same index-pack operation with different thread
counts. The output doesn't directly compare these, but anybody
interested in working on index-pack can manually compare the results.
For a normal regression run of the full perf-suite, though, this incurs
a significant cost to generate numbers nobody will actually look at;
about 25% of the total time of the test suite is spent in p5302. And the
low-thread-count runs are the most expensive part of it, since they're
(unsurprisingly) not using as many threads.
Let's skip these tests by default, but make it possible for people
working on index-pack to still run them by setting an environment
variable. Rather than make this specific to p5302, let's introduce a
generic mechanism. This makes it possible to run the full suite with
every possible test if somebody really wants to burn some CPU.

fetch-pack: in partial clone, pass --promisor
When fetching a pack from a promisor remote, the corresponding .promisor
file needs to be created. "fetch-pack" originally did this by passing
"--promisor" to "index-pack", but in
5374a290aa ("fetch-pack: write
fetched refs to .promisor", 2019-10-16), "fetch-pack" was taught to do
this itself instead, because it needed to store ref information in the
.promisor file.
This causes a problem with superprojects when transfer.fsckobjects is
set, because in the current implementation, it is "index-pack" that
calls fsck_finish() to check the objects; before
5374a290aa,
fsck_finish() would see that .gitmodules is a promisor object and
tolerate it being missing, but after, there is no .promisor file (at the
time of the invocation of fsck_finish() by "index-pack") to tell it that
.gitmodules is a promisor object, so it returns an error.
Therefore, teach "fetch-pack" to pass "--promisor" to index pack once
again. "fetch-pack" will subsequently overwrite this file with the ref
information.
An alternative is to instead move object checking to "fetch-pack", and
let "index-pack" only index the files. However, since "index-pack" has
to inflate objects in order to index them, it seems reasonable to also
let it check the objects (which also require inflated files).

dir: fix problematic API to avoid memory leaks
The dir structure seemed to have a number of leaks and problems around
it. First I noticed that parent_hashmap and recursive_hashmap were
being leaked (though Peff noticed and submitted fixes before me). Then
I noticed in the previous commit that clear_directory() was only taking
responsibility for a subset of fields within dir_struct, despite the
fact that entries[] and ignored[] we allocated internally to dir.c.
That, of course, resulted in many callers either leaking or haphazardly
trying to free these arrays and their contents.
Digging further, I found that despite the pretty clear documentation
near the top of dir.h that folks were supposed to call clear_directory()
when the user no longer needed the dir_struct, there were four callers
that didn't bother doing that at all. However, two of them clearly
thought about leaks since they had an UNLEAK(dir) directive, which to me
suggests that the method to free the data was too unclear. I suspect
the non-obviousness of the API and its holes led folks to avoid it,
which then snowballed into further problems with the entries[],
ignored[], parent_hashmap, and recursive_hashmap problems.
Rename clear_directory() to dir_clear() to be more in line with other
data structures in git, and introduce a dir_init() to handle the
suggested memsetting of dir_struct to all zeroes. I hope that a name
like "dir_clear()" is more clear, and that the presence of dir_init()
will provide a hint to those looking at the code that they need to look
for either a dir_clear() or a dir_free() and lead them to find
dir_clear().

this was an oversight, but a number of callers noticed memory leaks and
started free'ing these. Unfortunately, they did so somewhat haphazardly

diff reports that fact in a separate line containing "\ No newline at

written. mem_pool_init() does essentially the following (simplified
for purposes of explanation here):
void mem_pool_init(struct mem_pool **pool...)
{
*pool = xcalloc(1, sizeof(*pool));
It seems weird to require that mem_pools can only be accessed through a
pointer. It also seems slightly dangerous: unlike strbuf_release() or
strbuf_reset() or string_list_clear(), all of which put the data
structure into a state where it can be re-used after the call,
mem_pool_discard(pool) will leave pool pointing at free'd memory.
read-cache (and split-index) are the only current users of mem_pools,
and they haven't fallen into a use-after-free mistake here, but it seems
likely to be problematic for future users especially since several of
the current callers of mem_pool_init() will only call it when the
mem_pool* is not already allocated (i.e. is NULL).
This type of mechanism also prevents finding synchronization
points where one can free existing memory and then resume more
operations. It would be natural at such points to run something like
mem_pool_discard(pool...);
and, if necessary,
mem_pool_init(&pool...);
and then carry on continuing to use the pool. However, this fails badly
if several objects had a copy of the value of pool from before these
commands; in such a case, those objects won't get the updated value of
pool that mem_pool_init() overwrites pool with and they'll all instead
be reading and writing from free'd memory.
Modify mem_pool_init()/mem_pool_discard() to behave more like
strbuf_init()/strbuf_release()
or
string_list_init()/string_list_clear()
In particular: (1) make mem_pool_init() just take a mem_pool* and have
it only worry about allocating struct mp_blocks, not the struct mem_pool
itself, (2) make mem_pool_discard() free the memory that the pool was
responsible for, but leave it in a state where it can be used to
allocate more memory afterward (without the need to call mem_pool_init()
again).

mem-pool: add convenience functions for strdup and strndup
fast-import had a special mem_pool_strdup() convenience function that I

Merge branch 'so/log-diff-merges-opt'
Earlier, to countermand the implicit "-m" option when the
