mercurial: Changelog

help: mention '-T list' in templater topic

help: drop reference to glog in templates topic

templates: re-add template listing support We used to have --style nosuch to list templates, but --style is now merged with --template/-T where random strings are acceptable templates. So we reserve 'list' to allow listing templates.

help: use --template to specify existing style --style is deprecated since 3a35ba2681ec and 870d60294b04.

test-status: add test for removed-and-untracked state (BC) In Mercurial 3.0, "hg status" can list the same file twice if it was removed but still exists in working directory, i.e. removed by "hg forget": $ hg status --rev 0 removed R removed ? removed But since 65cdc6bab91e, untracked state, "?", is no longer displayed in this example. I think the new behavior is correct since a file should have single state, but if it is a bug, this patch should be dropped.

bundle2: only use callable return as reply handler When a bundle2 parts generator returns a non callable value, it should not be used as a reply handler. The changegroup part generator is already having this case of behavior when there is no changegroup to push. This changeset prevent a crash for user of the experimentable bundle2 feature.

resolve: report no argument warning using a hint With this change resolve and revert produce consistent output when run with no arguments: $ hg resolve abort: no files or directories specified (use --all to remerge all files) $ hg revert abort: no files or directories specified (use --all to revert all files)

revset: optimize baseset.__sub__ (issue4313) dd716807fd23 regressed performance of baseset.__sub__ by introducing a lazyset. This patch restores that lost performance by eagerly evaluating baseset.__sub__ if the other set is a baseset. revsetbenchmark.py results impacted by this change: revset #6: roots(0::tip) 0) wall 2.923473 comb 2.920000 user 2.920000 sys 0.000000 (best of 4) 1) wall 0.077614 comb 0.080000 user 0.080000 sys 0.000000 (best of 100) revset #23: roots((0:tip)::) 0) wall 2.875178 comb 2.880000 user 2.880000 sys 0.000000 (best of 4) 1) wall 0.154519 comb 0.150000 user 0.150000 sys 0.000000 (best of 61) On the author's machine, this slowdown manifested during evaluation of 'roots(%ln::)' in phases.retractboundary after unbundling the Firefox repository. Using `time hg unbundle firefox.hg` as a benchmark: Before: 8:00 After: 4:28 Delta: -3:32 For reference, the subset and cs baseset instances impacted by this change were of lengths 193634 and 193627, respectively. Explicit test coverage of roots(%ln::), while similar to the existing roots(0::tip) benchmark, has been added.
