This lookahead expression prevents the use of more modern and efficient regexp
engine. This slows down "hg status" and other operations.
Since the exception are only about vendored content whose addition is managed by
a script (`match vendor`), that script can deal with this exception by itself,
and it does since the last changeset..
So we drop the exception to unlock various performance improvements for status.
### Why does this improves things?
There improvement can come from different sources:
* Using the "re2" regexp engine to match ignored files and directories provide
a performance boost for vanillia mercurial installation and fs-monitor one in
various cases. To benefit from it, just install the "google-re2" packages and
mercurial will automatically uses it.
* Installing a Mercurial compiled with the Rust extensions unlock the use of a
more efficient code path for status that performs the necessary action in a
smarter and parallel ways, providing a significant boost. These extensions
are available on Linux and MacOs and some distribution have started to enable
them by default.
* Moving to a more modern "dirstate" format. The dirstate tracks the state of
the working copy. For a couple of years, Mercurial has a new format for this
information that is more efficient to read and update and tracks finer
grained information. This allow substantial improvement in the way we run
status. The Rust extensions are required to efficiently using this format.
* Using a pure-rust executable. Mercurial has a pure rust version (called
"rhg") that can handled a limited set of commands. It run without the
overhead of starting and initializing Python providing another very
significant boost to performance… but obviously requiring the Rust code path
to be usable.
### Quick Conclusion of the Benchmarks
(Putting that first for people who just want a quick read.)
* fsmonitor struggle on working copy with many modication,
* Using the "re2" binding from "google-re2" helps, especially for these cases
* On typical mozilla developer machine, the Rust variants match the fsmonitor
performance at worse and exceed it in multiple cases. Especially it does not
stuggle with the "many modification" case.
* On smaller machine, the Rust variants still provide a solid and reliable
performance win accross all operation. That make them preferable to fsmonitor.
* The rust variants matches "git status" performance on equivalement workload.
The pure Rust version significantly outperforms it.
### Benchmarks descriptions
Machines
--------
We ran benchmark on two different machines:
* A i7-7700K 4 physical / 4 logical cores released in Jan 2017
To see performance in "low" parallelism case.
* A i9-9900K 8 physical / 16 logical cores released in October 2019
To see performance in a "high" parallism case.
In both cases the repositories lived in a btrfs file system backed by solid
state disks (ssd or nvme) and the machines had enough ram to keep caches in
memory.
I also ran benchmarks on a more modern i7-1370P release on Jan 2023, and the
results were consistent with the i9-9900K ones.
Variants
--------
Benchmarks were run with multiple variants of Mercurial:
* python-re:
* no Rust extensions used,
* regex engine is the std-lib "re" module.
* fsmonitor is disabled
* using the dirstate-v1 format
* python-re2:
* no Rust extensions used,
* regex engine is the std-lib "re" module.
* fsmonitor is disabled
* using the dirstate-v1 format
* fsmonitor-re:
* no Rust extensions used,
* regex engine is the std-lib "re" module.
* fsmonitor is enabled and working at its best
* using the dirstate-v1 format
* fsmonitor-re2:
* no Rust extensions used,
* regex engine is the std-lib "re" module.
* fsmonitor is enabled and working at its best
* using the dirstate-v1 format
* rust-ds1:
* Rust extensions are used,
* regex engine from the Rust "regexp" crate.
* fsmonitor is disabled
* using the dirstate-v1 format
* rust-ds2:
* Rust extensions are used,
* regex engine from the Rust "regexp" crate.
* fsmonitor is disabled
* using the dirstate-v2 format
* rgh-ds1:
* Pure rust executable is used,
* regex engine from the Rust "regexp" crate.
* fsmonitor is disabled
* using the dirstate-v1 format
* rgh-ds2:
* Pure rust executable is used,
* regex engine from the Rust "regexp" crate.
* fsmonitor is disabled
* using the dirstate-v2 format
Commands
--------
We ran two kind of operations:
* `hg status` with the default output.
This command need to search for ignored and unknown files.
In this case improving the regex engine usually provides significant performance gain.
* `hg status --modified --added --removed --deleted`.
This command only need to check the state of tracked files.
In this case, improving the regex engine does not have much effect, but it
is interesting to compare the performance of the various implementation.

### Results Analysis
(full, raw number after this section)
About fsmonitor
---------------
Before diving into the improvements related to regex engine, we can note that
the benchmark show that fsmonitor provides a good boost in the pristine/clean cases, and
a noticeable but disappointing improvement in the very dirty case.
python-re fsmonitor-re
pristine-928b0540e421: 1.884 → 0.293 (-85%)
dirty-8f96f8c756ae: 2.157 → 1.440 (-33%)
Surprisingly when only listing tracked file (during commit for example), fsmonitor actually
get counter productive in the very dirty case
pristine-928b0540e421: 1.313 → 0.297 (-77%)
dirty-8f96f8c756ae: 0.993 → 1.272 (+28%)
In addition to being disappointing in the the very dirty case. The performance
with fsmonitor collapses when fsmonitor cannot use its cache. I observed 4
seconds execution time while setting up the brenchmark..
Improvement without involving Rust:
-----------------------------------
Using the re2 binding from the google-re2 package provides a small improvement
to plain python execution (about 15%). This case is relevant because this is
the one that will be used when fsmonitor cannot help or start.
python-re python-re2
pristine-928b0540e421: 1.884 → 1.650 (-15%)
dirty-8f96f8c756ae: 2.157 → 1.718 (-20%)
It does not make a difference when only listing tracked files as the hgignore is not involved.
python-re python-re2
pristine-928b0540e421: 1.313 → 1.332
dirty-8f96f8c756ae: 0.993 → 0.998
However, surprisingly, it helps fsmonitor quite a lot in in the dirty case
(dirty-8f96f8c756ae). Bringing fsmonitor performance in line with the plain
python one.
fsmonitor-re fsmonitor-re2
list-unknown 1.440 → 1.012 (-30%)
tracked only 1.272 → 0.840 (-34%)
So to conclude being able to use the "re2" regex engine save up to ⅓ of the
runtime of some operation and never slow things down. So that's a good win.
Improvement involving Rust variants:
------------------------------------
For the pristine-928b0540e421 case (all tracked files clean, no ignored files),
Rust provides speed boost "equivalent" (or better) to the one from fsmonitor.
The precise comparison depends of the parallelism level.
With the 4 physical / 4 logical core machine. The Python+Rust version is slower
than fsmonitor, using dirstate-v2 helping to close some of the gap with
fsmonitor. Using dirstate-v2 also allow the "rhg" version to become twice
faster than the fsmonitor version. Also keep in mind that even when a bit
slower, the performance of the rust version will be much more stable than
fsmonitor.
python-re2: 1.650
fsmonitor-re2: 0.296 (-82%)
rust-ds1: 0.542 (-67%)
rust-ds2: 0.368 (-77%)
rhg-ds1: 0.401 (-75%)
rhg-ds2: 0.132 (-92%)
With the 8 physical / 16 physical code machine, the Rust catch up with
fsmonitor performance much quicker. The dirstate-v1 is a little slower, but the
dirstate-v2 version is already faster. The pure rust is always faster.
python-re2: 1.430
fsmonitor-re2: 0.278 (-80%)
rust-ds1: 0.359 (-74%)
rust-ds2: 0.259 (-81%)
rhg-ds1: 0.235 (-83%)
rhg-ds2: 0.052 (-96%)
Talking about parallism. We see that the code scale well, doubling the
number of core bring about twice the performance which is great.
pristine-928b0540e421 4/4 8/16
rhg-ds1: 0.401 → 0.235 (× 1.70)
rhg-ds2: 0.132 → 0.052 (× 2.54)
clean-8f96f8c756ae
rhg-ds1: 0.286 → 0.169 (× 1.70)
rhg-ds2: 0.101 → 0.040 (× 2.52)
dirty-8f96f8c756ae
rhg-ds1: 0.380 → 0.234 (x 1.62)
rhg-ds2: 0.232 → 0.124 (x 1.87)
Comparing with git performance on the pristine-928b0540e421 case also yield
great results. Surprisingly, the variant with a Python overhead still beat (or
match) git performance in this case. The pure Rust executable is always
significantly faster. Below is a comparison grouped by comparable formats.
git status -s: 0.554 (without untracked cache)
rust-ds1: 0.359 (- 35%)
rhg-ds1: 0.235 (- 57%)
git status -s: 0.232 (with untracked cache)
rust-ds2: 0.259 (+ 11%)
rhg-ds2: 0.052 (- 77%)
The clean-8f96f8c756ae case (all tracked clean, many ignored files) show result
result similar to pristine-928b0540e421. "Low" parallism give good gains
without fully matching the fs monitor performance. The High parallism provide
similar performance. In both case we gain the benefit of more stable
performances.
(cores) 4/4 8/16
python-re2: 1.282 | 1.119
fsmonitor-re2: 0.243 (-81%) | 0.225 (-80%)
rust-ds1: 0.416 (-68%) | 0.282 (-75%)
rust-ds2: 0.303 (-76%) | 0.222 (-80%)
rhg-ds1: 0.286 (-78%) | 0.169 (-85%)
rhg-ds2: 0.101 (-92%) | 0.040 (-96%)
Things change quite a lot in the dirty-8f96f8c756ae case, where fsmonitor
struggled. The Rust variants still provides great speedup, significantly
beating the fsmonitor variants for both machines. (comparing to fsmonitor-re
this time)
(cores) 4/4 8/16
fsmonitor-re: 1.440 | 1.501
fsmonitor-re2: 1.012 (-30%) | 1.051 (-30%)

rust-ds2: 0.553 (-62%) | 0.483 (-68%)
rhg-ds1: 0.380 (-73%) | 0.234 (-84%)
rhg-ds2: 0.232 (-83%) | 0.124 (-91%)
Things is confirmed in the "listing tracked only" version of dirty-8f96f8c756ae
case were fs monitor was not really improving the situation compared to Python.

### Benchmark numbers for `hg status --modified --added --removed --deleted`
With this invocation, status no longer need to list directory content (or use
cache to skip that step). Status just need to check the known list of tracked
files.
