sslutil: remove out of place comment This comment likely got orphaned as a result of refactoring in this file. It isn't providing any useful value. So delete it.

largefiles: remove additional blank line between methods in localstore According to the coding style it should be a single blank line between functions.

revset: make head() honor order of subset The ordering of 'x & head()' was broken in 6a1a4c212d50 (revset: improve head revset performance, 2014-03-13). Presumably due to other optimizations since then, undoing that change to fix the order does not slow down the simple case of "hg log -r 'head()'" mentioned in that commit. I see a small slowdown from ~0.16s to about ~0.19s with 'not 0 & head()', but I'd say it's worth it for the correct output.

revsets: use itervalues() where only values are needed I don't think there will be a noticeable speedup, but it removes an unused variable.

revsets: passing a set to baseset() is not wrong Since 69c6e9623bdc (revset: force ascending order for baseset initialized from a set, 2016-04-04), it is safe to pass a revset to a baseset.

pyflakes: use pycompat.pickles to prevent error The pyflakes in my test box complain about pickle in pycompat. mercurial/pycompat.py:17: 'pickle' imported but unused

rebase: move local variable 'obsoletenotrebased' to the RR class

rebase: move restorestestatus function to be a method of the RR class

rebase: move local variables related to keeping things unchanged to the RR This commit moves the following variables, local to the rebase function to be fields of the rebaseruntime: -keepf -keepbranchesf -keepopen

rebase: move local variables 'date' and 'extrafns' to the RR class This commit moves the following variables, local to the rebase function to be fields of the rebaseruntime: -date -extrafns

rebase: move collapse-related local variables to the RR class This commit moves the following variables local to the 'rebase' function to be fields of the rebaseruntime class: -collapsef -collapsemsg

rebase: pass repo, ui and opts objects to the RR class constructor

check-code: build translation table for repquote in global for efficiency Rebuilding translation table (256 size) at each repquote() invocations is redundant. For example, this patch decreases user time of command invocation below from 18.297s to 13.445s (about -27%) on a Linux box. This command is main part of test-check-code.t. hg locate | xargs python contrib/check-code.py --warnings --per-file=0 This patch adds "_repquote" prefix to functions and variables factored out from repquote() to avoid conflict of name in the future.

check-code: detect "missing _() in ui message" more exactly Before this patch, "missing _() in ui message" rule overlooks translatable message, which starts with other than alphabet. To detect "missing _() in ui message" more exactly, this patch improves the regexp with assumptions below. - sequence consisting of below might precede "translatable message" in same string token - formatting string, which starts with '%' - escaped character, which starts with 'b' (as replacement of '\\'), or - characters other than '%', 'b' and 'x' (as replacement of alphabet) - any string tokens might precede a string token, which contains "translatable message" This patch builds an input file, which is used to examine "missing _() in ui message" detection, before '"$check_code" stringjoin.py' in test-contrib-check-code.t, because this reduces amount of change churn in subsequent patch. This patch also applies "()" instead of "_()" on messages below to hide false-positives: - messages for ui.debug() or debug commands/tools - contrib/debugshell.py - hgext/win32mbcs.py (ui.write() is used, though) - mercurial/commands.py - _debugchangegroup - debugindex - debuglocks - debugrevlog - debugrevspec - debugtemplate - untranslatable messages - doc/gendoc.py (ReST specific text) - hgext/hgk.py (permission string) - hgext/keyword.py (text written into configuration file) - mercurial/cmdutil.py (formatting strings for JSON)

revlog: add a fast path for "ambiguous identifier" Before fd1bb7c, if the C index.partialmatch raises RevlogError, the Python code raises "ambiguous identifier" error immediately, which is efficient. fd1bb7c took hidden revisions into consideration and forced the slow path enumerating the changelog to double-check hidden revisions. But it's not necessary if we know the revlog has no hidden revisions. This patch adds back the fast path for unfiltered revlogs.

import-checker: ensure cffi is always a system module I've had reports that this is not always happening, so whitelist it the way we whitelist other problem cases.
