store: stop relying on a `revlog_type` property We want to know if a file is related to a revlog, but the rest is dealt with differently already, so we simplify things further. as a bonus, this cleanup This provides a small but noticeable speedup. The number below use `hg perf::stream-locked-section` to measure the time spend in the locked section of the streaming clone. Number are run on various repository and compare different steps.: 1) the effect of this patchs, 2) the effect of the cleanup series, 2) current state compared to because large refactoring. All benchmarks are run on linux with Python 3.10.7. ### Effect of this patch # mercurial-2018-08-01-zstd-sparse-revlog # benchmark.name = perf-stream-locked-section before: 0.030246 seconds after: 0.029274 seconds (-3.21%) # pypy-2018-08-01-zstd-sparse-revlog before: 0.545012 seconds after: 0.520872 seconds (-4.43%) # netbeans-2018-08-01-zstd-sparse-revlog before: 2.719939 seconds after: 2.626791 seconds (-3.42%) # mozilla-central-2018-08-01-zstd-sparse-revlog before: 6.304179 seconds after: 6.096700 seconds (-3.29%) # mozilla-try-2019-02-18-zstd-sparse-revlog before: 14.142687 seconds after: 13.640779 seconds (-3.55%) ### Effect of this series A small but sizeable speedup # mercurial-2018-08-01-zstd-sparse-revlog before: 0.031122 seconds after: 0.029274 seconds (-5.94%) # pypy-2018-08-01-zstd-sparse-revlog before: 0.589970 seconds after: 0.520872 seconds (-11.71%) # netbeans-2018-08-01-zstd-sparse-revlog before: 2.980300 seconds after: 2.626791 seconds (-11.86%) # mozilla-central-2018-08-01-zstd-sparse-revlog before: 6.863204 seconds after: 6.096700 seconds (-11.17%) # mozilla-try-2019-02-18-zstd-sparse-revlog before: 14.921393 seconds after: 13.640779 seconds (-8.58%) ### Current state compared to the pre-refactoring state The refactoring introduced multiple string manipulation and dictionary creation that seems to induce a signifiant slowdown Slowdown # mercurial-2018-08-01-zstd-sparse-revlog 6.4.3: 0.019459 seconds after: 0.029274 seconds (+50.44%) ## pypy-2018-08-01-zstd-sparse-revlog 6.4.3: 0.290715 seconds after: 0.520872 seconds (+79.17%) # netbeans-2018-08-01-zstd-sparse-revlog 6.4.3: 1.403447 seconds after: 2.626791 seconds (+87.17%) # mozilla-central-2018-08-01-zstd-sparse-revlog 6.4.3: 3.163549 seconds after: 6.096700 seconds (+92.72%) # mozilla-try-2019-02-18-zstd-sparse-revlog 6.4.3: 6.702184 seconds after: 13.640779 seconds (+103.53%)
