revlog: remove unnecessary output parameter from node_check() The "nodelen" output parameter is always set to 20 if the function returns successfully. Differential Revision: https://phab.mercurial-scm.org/D4026

narrow: move status-filtering to core and to ctx One of my recent changes from repo.status(ctx1, ctx2) to ctx1.status(ctx2) broke some of our Google-internal tests. The problem turned out to be that the narrow extension was overriding repo.status() to make it filter out paths outside the narrowspec. When I changed to ctx1.status(ctx2), then that filtering obviously got lost. ctx.status() seems like a better method to do the filtering in, so this patch moves the filtering into that method, thereby also moving it out of the extension and into core.

amend: support "history-editing-backup" config option Now, amend is in the list of those history editing commands which support `history-editing-backup` config option. If you don't want to store any backup then just use this config. [ui] hisotry-editing-backup = False Current status of list of history editing commands which support this config: 1. histedit 2. rebase 3. amend Differential Revision: https://phab.mercurial-scm.org/D3968

rebase: move "backup" flag to rebaseruntime It was getting messy to populate "backup" flag to calls of `_finishrebase()` and `_prepareabortorcontinue`, so made some changes to move "backup" flag to rbsrt. Differential Revision: https://phab.mercurial-scm.org/D4055

i18n: format warning of hggettext in standard compiler error style Now, hggettext specific warning messages are formatted in: FILENAME:LINENO:MESSAGE This allows editors to jump into corresponded line easily.

i18n: omit redundant translatable synopsis text to avoid xgettext warning This empty translatable synopsis text causes xgettext warning below: Empty msgid. It is reserved by GNU gettext: gettext("") returns the header entry with meta information, not the empty string. This "synopsis" argument of @command annotation is omitable.

i18n: avoid substitution of PYFILES at runtime for readability of output This substitution decreases readability of "make update-pot" output, because PYFILES consists of many files. This patch makes "make update-pot" show "find mercurial hgext doc -name '*.py'" instead of many *.py files at runtime.

help: add quotes to a few commands we point to I didn't know that 'hg help "revsets.x or y"' was valid syntax, so the quoting is extra useful here to make it clear that that is an actual command. Differential Revision: https://phab.mercurial-scm.org/D4059

exchange: move simple narrow changegroup generation from extension The narrow extension completely replaced the function generating the changegroup part when a narrow changegroup was requested. Previous commits have taught the in-core changegroup code how to filter files based on a matcher. This commit teaches the in-core bundle2 part generation code to construct a matcher based on arguments. It will also emit a bundle2 part describing the narrow spec. I believe the changegroup part generation code in the narrow extension is now limited to ellipsis serving mode. i.e. core is now capable of narrow changegroup generation when ellipsis mode is disabled.
