Bug ID: 6059
Summary: `hg files` regression on c2aea007
Product: Mercurial
Version: 4.9rc0
Hardware: PC
OS: Linux
Status: UNCONFIRMED
Severity: bug
Priority: wish
Component: Mercurial
Assignee: bugzi...@mercurial-scm.org
Reporter: lothiral...@gmail.com
CC: mercurial-devel@mercurial-scm.org
Our performance test suite identified an `hg files` regression on c2aea007
Here are the numbers:
Benchmarks that have got worse:
before after ratio
[197f092b] [593718ff]
+ 739±4ms 871±5ms 1.18
time_files('mozilla-central-2018-08-01')
+ 748±7ms 872±5ms 1.17
time_files('mozilla-central-2018-08-01-sparse-revlog')
+ 353±2ms 399±2ms 1.13 time_files('netbeans-2018-08-01')
+ 352±2ms 397±2ms 1.13
time_files('netbeans-2018-08-01-sparse-revlog')
I took a quick look at the commit but I don't know if that's an overhead from
the `_isbuffered` call, the additional `ifs` or another part of the change.
This regression is likely to impact others commands but with much less impact
than `hg files`.
