locate: add pointer to files command in help

tests: fix breakage from locate deprecation

locate: deprecate in favor of files

formatter: add pickle format This gives convenient Python2 output. Python 3 users will need encoding=bytes.

commands: add hidden -T option for files/manifest/status/tags These commands have generic formatting support but no way to enable it yet. When this feature is more fully developed, this flag will be unhidden.

formatter: add json formatter

cmdutil: add json style to log-like commands Sadly, this can't be done with the normal templater like we do with XML due to JSON's inter-record comma rules.

encoding: add json escaping filter This ends up here because it needs to be somewhat encoding aware.

encoding: handle empty string in toutf8

formatter: make debug style match Python syntax

files: add new command unifying locate and manifest functionality

filelog: parsemeta stops returning unused key list Currently, only the returned meta dictionary is used. An upcoming change will use the returned text offset.

filelog: make parsemeta a public module function, to be used by censor module

filelog: make packmeta a public module function, to be used by censor

ui: move samplehgrcs from config config is generic code that doesn't know about Mercurial usage, so this was at the wrong layer

config: normalize style between user/global example configs

commit: correctly check commit mutability during commit --amend The right way to check if a context is mutable is to call .mutable(), not to compare .phase() with public.

histedit: check mutability of contexts correctly The right way to check if a context is mutable is to call .mutable(), not to compare .phase() with public.

manifest: mark addlistdelta and checkforbidden as module-private

convert: enable deterministic conversion progress bar for svn This produces slightly bad results when branches are in play, but overall I think it's probably worthwhile. We might be able to do better with branches somehow, but I haven't given it any thought.

convert: enable deterministic conversion progress bar for git

test-convert-git.t: add a test of convert progress bars for git We're about to enhance this support, so test the existing behavior so the improved behavior is obvious in the next patch.

convert: add support for deterministic progress bar on scanning phase This makes it possible to estimate how long the "scanning source" phase will take, if the specified source repo type supports a quick "how many changes" check.

test-convert-svn-move.t: remove stray '

manifest: move addlistdelta to module-level Again, there's no reason for this to be inside manifest.add, so we'll define it only once.

manifest: move checkforbidden to module-level There's no need for this function to be nested, so let's just define it once instead of every time manifest.add() gets called.

dirstate: add exception when calling setparent without begin/end (API) Adds an exception when calling dirstate.setparent without having first called dirstate.beginparentchange. This will prevent people from writing code that modifies the dirstate parent without considering the transactionality of their change. This will break third party extensions that call setparents.

dirstate: add test for exceptions during updates Adds a test that checks if the working copy parent and the working copy are in a good state if an exception happens between the time the working copy parent is set and the time the actual updates are recorded in the dirstate.
