Subject: [PATCH 09/15] refs/packed-backend.c: implement skip lists to avoid excluded pattern(s)
Date: Mon, 8 May 2023 18:00:08 -0400 [thread overview]
Message-ID: <a39d1107c1f3e9fbd859a23aed72e63bbd394fa2.1683581621.git.me@ttaylorr.com> (raw)
In-Reply-To: <cover.1683581621.git.me@ttaylorr.com>
When iterating through the `packed-refs` file in order to answer a query
like:
$ git for-each-ref --exclude=refs/__hidden__
it would be useful to avoid walking over all of the entries in
`refs/__hidden__/*` when possible, since we know that the ref-filter
code is going to throw them away anyways.
In certain circumstances, doing so is possible. The algorithm for doing
so is as follows:
- For each excluded pattern, find the first record that matches it,
and the first pattern that *doesn't* match it (i.e. the location
you'd next want to consider when excluding that pattern).
- Sort the patterns by their starting location within the
`packed-refs` file.
- Construct a skip list of regions by combining adjacent and
overlapping regions from the previous step.
- When iterating through the `packed-refs` file, if `iter->pos` is
ever contained in one of the regions from the previous steps,
advance `iter->pos` past the end of that region, and continue
enumeration.
Note that this optimization is only possible when none of the excluded
pattern(s) have special meta-characters in them. To see why this is the
case, consider the exclusion pattern "refs/foo[a]". In general, in order
to find the location of the first record that matches this pattern, we
could only consider up to the first meta-character, "refs/foo". But this
doesn't work, since the excluded region we'd come up with would include
"refs/foobar", even though it is not excluded.
There are a few other gotchas worth considering. First, note that the
skip list is sorted, so once we skip past a region, we can avoid
considering it (or any regions preceding it) again. The member
`skip_pos` is used to track the first next-possible region to jump
through.
Second, note that the exclusion list is best-effort, since we do not
handle loose references, and because of the meta-character issue above.
In repositories with a large number of hidden references, the speed-up
can be significant. Tests here are done with a copy of linux.git with a
reference "refs/pull/N" pointing at every commit, as in:
$ git rev-list HEAD | awk '{ print "create refs/pull/" NR " " $0 }' |
git update-ref --stdin
$ git pack-refs --all
, it is significantly faster to have `for-each-ref` skip over the
excluded references, as opposed to filtering them out after the fact:
$ hyperfine \
'git for-each-ref --format="%(objectname) %(refname)" | grep -vE "^[0-9a-f]{40} refs/pull/"' \
'git.compile for-each-ref --format="%(objectname) %(refname)" --exclude="refs/pull"'
Benchmark 1: git for-each-ref --format="%(objectname) %(refname)" | grep -vE "^[0-9a-f]{40} refs/pull/"
Time (mean ± σ): 802.7 ms ± 2.1 ms [User: 691.6 ms, System: 147.0 ms]
Range (min … max): 800.0 ms … 807.7 ms 10 runs
Benchmark 2: git.compile for-each-ref --format="%(objectname) %(refname)" --exclude="refs/pull"
Time (mean ± σ): 4.7 ms ± 0.3 ms [User: 0.7 ms, System: 4.0 ms]
Range (min … max): 4.3 ms … 6.7 ms 422 runs
Summary
'git.compile for-each-ref --format="%(objectname) %(refname)" --exclude="refs/pull"' ran
172.03 ± 9.60 times faster than 'git for-each-ref --format="%(objectname) %(refname)" | grep -vE "^[0-9a-f]{40} refs/pull/"'
Using the skip list is fairly straightforward (see the changes to
`refs/packed-backend.c::next_record()`), but constructing the list is
not. To ensure that the construction is correct, add a new suite of
tests in t1419 covering various corner cases (overlapping regions,
partially overlapping regions, adjacent regions, etc.).
