revset: translate node directly with changelog in 'head'...
revset: translate node directly with changelog in 'head' Using 'repo[X]' is much slower because it creates a 'changectx' object and goes though multiple layers of code to do so. It is also error prone if there is tags, bookmarks, branch or other names that could map to a node hash and take precedence (user are wicked). This provides a significant performance boost on repository with a lot of heads. Benchmark result for a repo with 1181 heads. revset: head() plain min last reverse 0) 0.014853 0.014371 0.014350 0.015161 1) 0.001402 9% 0.000975 6% 0.000874 6% 0.001415 9% revset: head() - public() plain min last reverse 0) 0.015121 0.014420 0.014560 0.015028 1) 0.001674 11% 0.001109 7% 0.000980 6% 0.001693 11% revset: draft() and head() plain min last reverse 0) 0.015976 0.014490 0.014214 0.015892 1) 0.002335 14% 0.001018 7% 0.000887 6% 0.002340 14% The speed up is visible even when other more costly revset are in use revset: head() and author("mpm") plain min last reverse 0) 0.105419 0.090046 0.017169 0.108180 1) 0.090721 86% 0.077602 86% 0.003556 20% 0.093324 86%

setup: install translation files as package data...
 r9999 When Mercurial accepts more than one revision, they may be specified
individually, or provided as a topologically continuous range,
separated by the ":" character.
The syntax of range notation is [BEGIN]:[END], where BEGIN and END are
revision identifiers. Both BEGIN and END are optional. If BEGIN is not
specified, it defaults to revision number 0. If END is not specified,
it defaults to the tip. The range ":" thus means "all revisions".
If BEGIN is greater than END, revisions are treated in reverse order.
A range acts as a closed interval. This means that a range of 3:5
gives 3, 4 and 5. Similarly, a range of 9:6 gives 9, 8, 7, and 6.
