outage, restored from backup --simon, Thu, 15 Feb 2007 20:53:38 +0000 reply
The server was down for a day due apparently to db corruption. It has been restored from a 2007/02/14 04:13 MST backup; any changes since then will need to be redone. Sorry for the disruption.

The joyful.com/zwiki.org/wiki.zope.org server was down for 19 hours due to some insane apache/zope/qmail/curl deadlock. Service has been restored.

An update on the wiki.zope.org/*.zwiki.org server for 2007/3/7:
Uptime troubles and investigations continue, and there have been significant outages as I haven't always been able to respond quickly. Thanks for your patience; we are making progress.
- Yesterday, an automated zope restart failed because of an error related to the (new) permanent zeo cache. I have gone back to temporary zeo cache.
- Today, zope stopped responding as both threads blocked trying to send mail. (I was able to see this from the traceback in event.log when I killed them.) Some sort of deadlock with qmail. This has been happening before so it's good to pinpoint it. I will switch to MaildropHost asap which may help.
I have been watching the server processes and tuning various things. Sascha Welter implemented http conditional-get handling for zwiki, and also configured httpcaches for several of the (dynamic) front pages. We have reduced cpu load a lot, and made loading of previously-visited pages a lot more snappy!
(Note there is an open issue with conditional-get: Firefox and Mozilla users with default settings will often have to reload after an edit to see the changes. We have some ideas to prevent this, until then I might have to revert this feature.)
Edit operations, especially those touching many pages, can still be rather slow as we are still memory-constrained (~250M quota). The server is currently running two zope threads with cache-size 3000. When it exceeds quota (be it through normal growth or memory leak) it is restarted; this is still happening one or more times per day. Restarting and warming up the caches is quite slow (can be 5-10 minutes if I'm not mistaken).
I have gone from 7-day to 2-day nightly packs to keep zodb size around the 1G mark (and within the 8G disk quota).
Martijn Faassen is pursuing a possible new, beefier hosting situation.
Thanks also to Sascha Welter, Michael Haubenwallner, Christian Theune and anyone else I've forgotten, for dropping by #zwiki on irc.freenode.net and helping to troubleshoot and fix issues.
Cheers! - Simon
PS I seem to have too many places to post such news: - zope-web list/gmane.comp.web.zope.websites newsgroup - http://wiki.zope.org/AboutThisSite - http://wiki.zope.org/zope3/AboutThisSite - http://wiki.zope.org/zope2/AboutThisSite - http://zwiki.org/GeneralDiscussion I will probably pick just the first 2 or 3 henceforth.
new wiki.zope.org server --Simon Michael, Wed, 18 Apr 2007 05:21:57 +0000 reply
Zopistas - I'm pleased to announce that wiki.zope.org has moved to a more
powerful server. You should now or very soon see wiki.zope.org pointing to
194.109.109.175. This is also the machine hosting foundation.zope.org,
kindly provided by amaze.nl.
We are in shake-down mode - all wikis should be working as before, including mail-out and mail-in. There is one open issue - some pages are giving UnicodeDecodeError? (http://zwiki.org/1330 , help welcome) - please report any others.
More details:
ZSyncer worked like a champ here. I used it to transfer all the wikis over in one shot last week, did the testing, and when dns changed today, did one more sync to transfer the recent changes.
old server: 256M, 4-cpu VPS, zope 2.9.4, zeo, cache-size 3000 new server: 768M, 1-cpu VPS, zope 2.10.3, non-zeo for now, cache-size 30000
I haven't measured much speedup of transactions on the new server - a mild slowdown, in fact, for reasons unknown (single vs 4 cpus ?). But zope finally has enough ram to breathe, so I expect things to feel quicker, and much more consistent. Restarts now take 10s instead of 3 minutes, and will hopefully be a rare manual event.
Yay! Thanks to Martijn Faassen, Bas van der Linden, and Andrew Sawyer for their help.
I am available for consulting work! Check out the updated http://joyful.com to find out more.
Best, -Simon
zope2 wiki updates --simon, Wed, 16 May 2007 05:31:28 +0000 reply
I cleaned up the skin template and the front page a little. Also some unicode errors were fixed and page rendering should be a bit faster.
wiki repairs --simon, Thu, 19 Jul 2007 19:27:43 +0000 reply
I have just repaired some deletes and reparents that had disorganized the zope2 wiki. Thanks to Michael Haubenwallner for spam defense over the last few days.
I had to get rid of the hierarchy cache, so most subtopics are now sorted alphabetically.
Products reparented --simon, Fri, 28 Sep 2007 18:52:20 +0000 reply
Let's try Products as a top-level category on the front page.. it's one of the main things here.
cleanup --simon, Thu, 08 May 2008 22:39:43 +0000 reply
Some hierarchy and front page cleanup has begun, sparked by #zope chat. If you wish to help, please join in.
