Bug ID: 6121
Summary: Evolve and Topic have a shared global enabled state
Product: Mercurial
Version: unspecified
Hardware: PC
OS: Mac OS
Status: UNCONFIRMED
Severity: feature
Priority: wish
Component: evolution
Assignee: bugzi...@mercurial-scm.org
Reporter: mar...@python-blog.com
CC: mercurial-devel@mercurial-scm.org,

In short, within the same process that handles different repositories enabling
evolve+topic has an influence on other repositories.
Having RepoA (with evolve+topic) and RepoB (without any extensions)
If we first do some operations on RepoA then RepoB operations fails with
exceptions related to missing topic support, e.g.
```

AttributeError: 'lfilesrepo' object has no attribute 'currenttopic'
```
This looks like some sort of global state of those extensions loaded. A simple
config for repoA looks like that:
extensions.evolve=1
extensions.topic=1
While repoB has an empty config. Even setting something like this doesn't fix
the problem.
extensions.evolve=!
extensions.topic=!
This is very important for us since it blocks us from having Evolve+Topic
support in latest RhodeCode releases.
