Fixed, thanks! > I'm excited to see the official wiki has been moved to the new darcs backend > now. Indeed, we've reached a point where there's no turning back. The convenience of being able to edit the wiki from darcs darcs get http://darcs.net/darcs-wiki is such that we would find it painful to go back to Moin. Not to mention (fingers crossed) the spammers we've avoided (perhaps by the user account textcha of "what revision control system is this wiki about?") Wiki not there? --------------- That said, we're still having some performance problems (viewing pages is fine, and editing can be a bit slow) and some memory consumption issues (we've had to restart darcsit at least twice in the past couple of weeks; if you notice the wiki being down, do let us know). If I understand Gwern correctly, this is hard to pin down to any one cause. Factors which may be involved: * "darcs changes foo" performs poorly on a large history (3k revisions). Hopefully, Benedikt's filecache work will improve matters. [I'm guessing that "darcs show contents --match 'hash foo'", which I think filestore uses is another variant of this http://bugs.darcs.net/issue1477] * darcsit/filestore potentially calling darcs too much (or calling unnecessarily expensive parts of darcs) * GHC's internal memory allocator never releases memory back to the OS - http://hackage.haskell.org/trac/ghc/ticket/698 - http://groups.google.com/group/gitit-discuss/browse_thread/thread/a50cb997d42bdf5e How can we fix this? -------------------- I think we need to get that filecache stuff in as soon as sanely possible, and also find a kind GHC hacker to take on GHC bug #698. For the latter, I notice it's been marked of "Moderate (1 day)" difficulty, and it would benefit people with long running programs like darcsit (and perhaps any of the other happstack stuff?). So if you're up for a little GHC hacking, Darcs needs you! -- Eric Kow <http://www.nltg.brighton.ac.uk/home/Eric.Kow> PGP Key ID: 08AC04F9
