update: do not use the term 'update' when mentioning reverting one file and give a more precise hint for how to revert such a file I'm using the term 'revision' instead of 'changeset' in this change to be consistent with the REV we use in the synopsis.

cmdserver: fix read-loop string concatenation

dispatch: check for None before closing repo We were trying to call close() if repo == None and req.repo != None. This can happen when running commands that don't take a repo.

revert: mention update in hint of abort when reverting to non-parent and explicitly warn about uncommitted changes Examples: BEFORE: $ hg par -q 7:e81a2efd53d4 $ hg revert -r 2 abort: no files or directories specified (use --all to discard all changes) AFTER: Clean working directory (revert can be easily undone, no edits to be lost): $ hg revert -r 2 abort: no files or directories specified (use --all to revert all files, or 'hg update 2' to update) Uncommitted changes (revert --all *does* discard edits and is pretty hard to undo or even impossible if --no-backup is specified): $ hg revert -r 2 abort: no files or directories specified (uncommitted changes, use --all to discard all changes, or 'hg update 2' to update)

update: clarify that update changes the parent revison

revset: fix aliases with 0 or more than 2 parameters The existing code seemed to have incorrect assumptions about how parameter lists are represented by the parser. Now the match and replace functions have been merged and simplified by using getlist().

match: fix bug caused by refactoring in cfc89398f710

revert: be more helpful on uncommitted merges BEFORE: $ hg revert abort: no files or directories specified (use --all to discard all changes) AFTER: $ hg revert abort: no files or directories specified (uncommitted merge, use --all to discard all changes, or 'hg update -C .' to abort the merge)

opener: add self._audit (issue2862)

cmdserver: write the hello message as one chunk on the 'o' channel This is a guaranteed by the protocol: clients know they need to read one chunk off of the 'o' channel and treat that as the hello message. They should ignore fields they don't recognize so they stay compatible with new versions of the server in case we decide to add something.

fileset: copied takes no arguments

revset and fileset: fix typos in parser error messages

fileset: use ParseError pos field correctly The pos field is intended to describe the position of the error - it should not be used for other potentially interesting information.

revset: fix parameter name in implementation of follow()

revert: be more explicit that changes are lost BEFORE: $ hg revert abort: no files or directories specified (use --all to revert all files) AFTER: $ hg revert abort: no files or directories specified (use --all to discard all changes)

dispatch: do not close the request repo Closing here means we've closed the repo passed to us in the request, which is not our responsibility. This is essential for bundlerepo, and possibly other localrepository subclasses who do something in their close().

hook: write hook output to ui fout descriptor output on stderr will also be written to ui.fout, unless sys.__stdout__ is passed in (see util.system), thus not changing previous behavior. This fixes a bug where hooks run through the command server would mess up with the command protocol, sending non-channeled data to the client.

check-code: don't mark debug messages for translation

i18n: remove translation of debug messages

cmdserver, runcommand: properly handle the client sending no arguments No real reason for a client to do this, but still possible. Previously if the client sent no arguments, a list with an empty string [''] would be used as the arguments to dispatch, which would cause hg to complain about an ambiguous command. Instead, we simply check for no arguments and use an empty list instead (which is equivalent to invoking hg with no args on the command line).

cmdserver: don't raise EOFError when trying to read 0 bytes from the client

i18n: extract docstrings from fileset module

Backed out changeset 1ec8bd909ac3 Debug messages should not be translated.
