Mercurial 1.1 does not work with Trac 0.11.2

[maxim.vuets@…]

The following error happens on the /browser and /changeset pages (also maybe some else, but I don't know it yet).

This is because of ​hg:9fe97eea5510. I'll take this opportunity to switch to the filectx API, as this should ensure compatibility with former versions (probably not below 1.0, but at this stage I think we can forget about those versions).

[Christian Boos]

Should be fixed with r7742 and r7743 (for Trac trunk and MultipleRepositorySupport branch). I also tested these versions with Mercurial 1.0, and it seems to work fine as well.

I didn't see any other problems so far, but don't hesitate to reopen this ticket if other compatibility issues arise.

Also, I don't plan to support the 0.10 version of the plugin, but if someone contributes a patch, I could apply it if the patch takes care of compatibility with older (pre-1.0) Hg versions.

Replying to cboos:

Should be fixed with r7742 and r7743 (for Trac trunk and MultipleRepositorySupport branch). I also tested these versions with Mercurial 1.0, and it seems to work fine as well.

I tried r7742 for 0.11.2 and did not face with any problems. It is just very slow, so I'm waiting for applying patches from #7746 (;
