hgrc.5: whether bcc is prompted for is up to the extension There is no code in mail.py that forbids an extension to prompt for bcc.

many, many trivial check-code fixups

Introduce check-code.py check-code is a simple regex-based framework for checking our code and tests for common style and portability errors. Currently, it knows a fair amount about our Python and C style, and a little about common shell script portability problems.

tests: Don't use $PWD $PWD doesn't work with solaris sh - use `pwd` instead

mq: Do not translate import message that are appended to commits. We should not translate the "imported patch" message. The translated message confuses the detection whether the user has not updated the commit message yet. We try to avoid to translate generated commit messages.

subrepo: handle svn externals and meta changes (issue1982) - Detect changes to meta on regular and external entries - Do not try to commit external entries

subrepo: svn xml output is much easier to parse That's especially true with status flags: there are different fields and values for regular changes, meta changes, externals changes and externals meta changes.

subrepo: make svn use C locale for portability My reasons to do c2e2a5e6c36b were wrong. We want to have non-localized svn output while preserving current locale for input arguments and svn internals. This is achieved by setting LC_MESSAGE=C.

summary: L10N messages hide clean-ness of workdir from 'hg summary' 'hg summary' recognizes workdir as clean by searching for 'clean' is in own output text. But 'clean' is one of I18N target texts, so 'hg summary --quiet' behaves incorrectly in non-English locale.

copies: speed up copy detection On some large repos, copy detection could spend > 10min using fctx.ancestor() to determine if file revisions were actually related. Because ancestor must traverse history to the root to determine the GCA, it was doing a lot more work than necessary. With this replacement, same status -r a:b takes ~3 seconds.

hgweb: request: strip() form values Entering "<correct_cset_hash> " in the search form was not returning anything. This happens relatively often, due to HTML formatting: when copy/pasting a cset hash from the web, selection might contain surrounding spaces.

templatekw: fix extras, manifest and showlist args (issue1989) Removing the explicit parameters from keywords signature is easier than copying and reproducing the original argument list.
