topics: consistently use empty string instead of None This agrees with repo.currenttopic which uses ''. A subsequent patch is going to provide a context topic method that returns the empty string.

topics: drop debugging print in rebase

topics: allow commits that only change topic (issue4725) This allows amend to change topics. It also matches the behavior of branches.

topics: add listnames hook so completion works

rewrite: use a lock and transaction as spotted by devel warnings

topics: only apply topic to commits of the working copy

rebase: teach rebase how to copy topics

topic: wrap the underlying update function rather than the command This more properly manages the updates done by things like rebase.

commit: add a topic field to the in-editor commit text

topic: only require obsolete support for --change

commit: add a --topic flag

topic: note when switching topics

summary: add topic summary hook

topics: add command summary

docs: fix format of extension docstring

constants: extract key for extra into a constant It might be prudent to prefix it, and regardless it was bugging me to have it repeated everywhere.

topic: add ability to change topic of non-public changes This is a little crude, but it gets the job done. You probably don't want to use this without evolution for now.

revset: add a topic() revset for querying topics

topic: disallow use of topics without obsolete enabled This is a prelude to allowing changing topics. The experience will be disastrous without obsolete markers, so let's just preempt any potential problems.

topic: use repo.set() where we need a changectx anyway I always forget repo.set() exists and use repo.revs(). Sigh.

testlib: enable rebase and obsolete for easier testing

Initial dumb version of topics.

serveronly: deduplicate code with the main evolve extension Now that 'serveonly' is a sub module of evolve. We can access its content in evolve. As a result we stop duplicating code all common parts are defined in the 'serveronly' module and imported by evolve when needed.

serveronly: clean up imports remove unused one and arrange them

compat: just use '_callcompressable' That API is available in all version we supports.

compat: drop bookmark compatibility layer All the version we now supports have the 'new' API.

compat: drop compat for older wireproto implementation We only support Mercurial version with these attributes.

compat: always use the strip revset from core We only support versions that defines it.

compat: drop support for ancestral pushop object Pushoperation object have a 'cgresult' attribute in all the versions we support.

compat: drop compatibility layer around update We now support only versions with the new API.
