narrow: when writing treemanifests, skip inspecting directories outside narrow This provides significant speed benefits when narrow and treemanifests are in use, see the timing numbers below. Note that like previously, differences of <5% are considered noise. The below timing numbers are in the same style as previously (example: ee7ee0c516ca). 'before' is 9db85644, and does not include that example commit's improvements. diff --git: repo | N | T | before (mean +- stdev) | after (mean +- stdev) | % of before ------+---+---+------------------------+-----------------------+------------ m-u | | | 1.327 s +- 0.051 s | 1.296 s +- 0.009 s | 97.7% m-u | | x | 1.310 s +- 0.020 s | 1.295 s +- 0.015 s | 98.9% m-u | x | | 1.295 s +- 0.018 s | 1.296 s +- 0.007 s | 100.1% m-u | x | x | 83.5 ms +- 0.8 ms | 84.1 ms +- 0.8 ms | 100.7% l-d-r | | | 205.1 ms +- 3.5 ms | 205.0 ms +- 3.8 ms | 100.0% l-d-r | | x | 194.2 ms +- 5.6 ms | 192.3 ms +- 4.3 ms | 99.0% l-d-r | x | | 99.1 ms +- 2.2 ms | 97.8 ms +- 0.9 ms | 98.7% l-d-r | x | x | 66.2 ms +- 1.0 ms | 67.2 ms +- 2.7 ms | 101.5% diff -c . --git: repo | N | T | before (mean +- stdev) | after (mean +- stdev) | % of before ------+---+---+------------------------+-----------------------+------------ m-u | | | 233.9 ms +- 1.9 ms | 235.6 ms +- 5.1 ms | 100.7% m-u | | x | 151.4 ms +- 1.2 ms | 152.2 ms +- 2.0 ms | 100.5% m-u | x | | 234.8 ms +- 2.7 ms | 235.0 ms +- 2.7 ms | 100.1% m-u | x | x | 127.8 ms +- 2.1 ms | 126.0 ms +- 1.1 ms | 98.6% l-d-r | | | 82.5 ms +- 1.6 ms | 82.3 ms +- 2.0 ms | 99.8% l-d-r | | x | 3.742 s +- 0.017 s | 3.819 s +- 0.208 s | 102.1% l-d-r | x | | 84.4 ms +- 1.5 ms | 83.2 ms +- 1.0 ms | 98.6% l-d-r | x | x | 751.2 ms +- 5.0 ms | 755.8 ms +- 12.9 ms | 100.6% rebase -r . --keep -d .^^: repo | N | T | before (mean +- stdev) | after (mean +- stdev) | % of before ------+---+---+------------------------+-----------------------+------------ m-u | | | 5.519 s +- 0.038 s | 5.526 s +- 0.057 s | 100.1% m-u | | x | 5.588 s +- 0.048 s | 5.607 s +- 0.061 s | 100.3% m-u | x | | 5.520 s +- 0.044 s | 5.546 s +- 0.059 s | 100.5% m-u | x | x | 586.6 ms +- 12.8 ms | 554.9 ms +- 21.2 ms | 94.6% <-- l-d-r | | | 629.8 ms +- 5.5 ms | 627.4 ms +- 6.6 ms | 99.6% l-d-r | | x | 6.165 s +- 0.058 s | 6.255 s +- 0.303 s | 101.5% l-d-r | x | | 270.2 ms +- 2.3 ms | 271.4 ms +- 2.7 ms | 100.4% l-d-r | x | x | 4.700 s +- 0.025 s | 1.651 s +- 0.016 s | 35.1% <-- status --change . --copies: repo | N | T | before (mean +- stdev) | after (mean +- stdev) | % of before ------+---+---+------------------------+-----------------------+------------ m-u | | | 215.4 ms +- 2.3 ms | 216.5 ms +- 4.2 ms | 100.5% m-u | | x | 132.9 ms +- 1.2 ms | 132.0 ms +- 1.4 ms | 99.3% m-u | x | | 217.0 ms +- 1.9 ms | 215.4 ms +- 1.9 ms | 99.3% m-u | x | x | 108.6 ms +- 1.0 ms | 108.2 ms +- 1.5 ms | 99.6% l-d-r | | | 80.0 ms +- 1.3 ms | 80.5 ms +- 1.1 ms | 100.6% l-d-r | | x | 3.916 s +- 0.187 s | 3.966 s +- 0.236 s | 101.3% l-d-r | x | | 84.4 ms +- 3.1 ms | 83.9 ms +- 1.1 ms | 99.4% l-d-r | x | x | 758.0 ms +- 8.2 ms | 753.5 ms +- 5.0 ms | 99.4% status --copies: repo | N | T | before (mean +- stdev) | after (mean +- stdev) | % of before ------+---+---+------------------------+-----------------------+------------ m-u | | | 1.905 s +- 0.025 s | 1.910 s +- 0.044 s | 100.3% m-u | | x | 1.892 s +- 0.009 s | 1.895 s +- 0.012 s | 100.2% m-u | x | | 1.891 s +- 0.012 s | 1.902 s +- 0.018 s | 100.6% m-u | x | x | 93.3 ms +- 0.9 ms | 93.4 ms +- 0.8 ms | 100.1% l-d-r | | | 570.7 ms +- 7.8 ms | 571.9 ms +- 18.5 ms | 100.2% l-d-r | | x | 561.5 ms +- 5.2 ms | 562.9 ms +- 6.1 ms | 100.2% l-d-r | x | | 171.7 ms +- 2.6 ms | 171.9 ms +- 1.2 ms | 100.1% l-d-r | x | x | 142.7 ms +- 2.0 ms | 140.3 ms +- 1.0 ms | 98.3% update $rev^; ~/src/hg/hg{hg}/hg update $rev: repo | N | T | before (mean +- stdev) | after (mean +- stdev) | % of before ------+---+---+------------------------+-----------------------+------------ m-u | | | 3.126 s +- 0.016 s | 3.128 s +- 0.015 s | 100.1% m-u | | x | 3.014 s +- 0.068 s | 3.008 s +- 0.031 s | 99.8% m-u | x | | 3.143 s +- 0.037 s | 3.184 s +- 0.086 s | 101.3% m-u | x | x | 308.0 ms +- 1.8 ms | 308.1 ms +- 5.7 ms | 100.0% l-d-r | | | 430.8 ms +- 4.5 ms | 436.4 ms +- 8.7 ms | 101.3% l-d-r | | x | 9.676 s +- 0.127 s | 9.945 s +- 0.272 s | 102.8% l-d-r | x | | 254.2 ms +- 3.3 ms | 255.7 ms +- 3.1 ms | 100.6% l-d-r | x | x | 1.571 s +- 0.030 s | 1.555 s +- 0.014 s | 99.0% Differential Revision: https://phab.mercurial-scm.org/D4606
