external link posting restricted --simon, Wed, 08 Nov 2006 00:04:09 -0800 reply
We just had our first spam incident on the zope wikis.. an identified user posted a bunch of links on 5 or so of the front pages. I've reduced the allowed number of external links per edit for identified users from unlimited to 10.
Also created this page for announcements/discussion pertaining to all wiki.zope.org wikis. Subscribe here if you'd like to receive these by mail.
disk quota exceeded messages --simon, Tue, 21 Nov 2006 10:55:41 -0800 reply
I apologize for any "Disk quota exceeded" problems you've seen. I have set up a weekly 7-day pack cron job which should help.
cleaned up wiki list --simon, Wed, 20 Dec 2006 13:15:44 -0800 reply
wiki.zope.org cleanup.
reparent now requires identification --simon, Fri, 26 Jan 2007 12:57:37 -0800 reply
Reparenting pages now requires a username in options. This should reduce junk reparent mails from the wikis.
outage, restored from backup --simon, Thu, 15 Feb 2007 20:53:36 +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.
server outage --simon, Sat, 24 Feb 2007 18:14:39 +0000 reply
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.
server news --simon, Wed, 07 Mar 2007 22:14:34 +0000 reply
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 MTA --simon, Wed, 21 Mar 2007 17:18:34 +0000 reply
I am switching mail server, from from qmail to postfix.. any disruptions in mail flow should be resolved soon.
front page cleanup --simon, Fri, 23 Mar 2007 20:00:30 +0000 reply
http://wiki.zope.org/wiki.zope.org has had a little cleanup and now shows the last edit date of each wiki.
outage --simon, Sun, 25 Mar 2007 16:26:01 +0000 reply
All wikis were down for several hours due to some new code I uploaded and thought was sufficiently tested. Sorry about that.
wiki.zope.org news 2007/3/27 --Simon Michael, Tue, 27 Mar 2007 20:17:39 +0000 reply
Hi all,
Fred Drake made a nice, very crisp style for the ZPT wiki, and I've installed it as the default for the zope wikis (the zope3 wiki's style is as before). See what you think.
I simplified and ramcached the index at http://wiki.zope.org and added a last edit date. Aside from the big two (zope2 and zope3) some of the other wikis are receiving some love, such as the ZPT wiki (Fred) and the ZODB wiki (Christian Theune).
I've been making progress on the various server instability issues. There have been more wiki and subscriber mail delivery outages (sorry!) but things feel pretty solid now, the two open problems being general slowness and a 17-minute restart once a day or so. Recent changes include:
- more watchdog scripts to monitor and correct various failure scenarios - replaced qmail with a more straightforward postfix setup - switched to MailDropHost? for zope mail sending - disabled http conditional get handling for now (for firefox users)
Meanwhile, Martijn Faassen and Bas van der Linden at Amaze have today hooked me up with a new server which so far is looking great - many thanks! This should lead to a more community-centric setup. I'll be testing there over the next days.
Best, -Simon
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
new wiki.zope.org server --Simon Michael, Wed, 18 Apr 2007 20:26:19 +0000 reply
I've added a workaround which seems to fix those pages with UnicodeDecodeErrors. There are other places such as the contents and recent changes which still can break. See http://zwiki.org/1330 for current status.
subscriber counts --simon, Wed, 18 Apr 2007 20:51:40 +0000 reply
The list of wikis now shows whole-wiki subscriber counts (page subscribers are ignored for now).
disappearing contents --simon, Wed, 06 Jun 2007 18:04:11 +0000 reply
This server is affected by an annoying bug in recent Zwiki where contents disappear. I've just restarted it as a temporary fix. http://zwiki.org/1335
upgrade --simon, Sat, 14 Jul 2007 16:53:01 +0000 reply
This site has been updated to latest Zwiki-darcs. Deleting a certain page was giving an error, now fixed.
make pages more indexable --simon, Tue, 25 Sep 2007 06:23:58 +0000 reply
I've disabled the 24-hour no-indexing period on the wiki.zope.org wikis, following comments by baijum and mgedmin. New and active pages should appear more quickly in google now. See http://thread.gmane.org/gmane.comp.web.zope.zwiki/13727 for explanation and discussion.
front pages fix --simon, Tue, 25 Sep 2007 22:17:00 +0000 reply
About half the wikis linked at wiki.zope.org were showing the wrong front page when clicked, due to a change several weeks ago. Fixed.
outage --simon, Sun, 14 Oct 2007 20:09:41 +0000 reply
The wikis were inaccessible for some period last night, due to some issue with apache. Bas restarted it.
update --Simon Michael, Tue, 05 Feb 2008 00:15:28 +0000 reply
I did this:
- investigated a little - we are running three zope servers in a xen instance with 512M ram, debian stable, apache 2.2.3-4. The wikis are running zope 2.10.3
- a 14-day pack of wiki.zope.org (3G -> 300M)
- installed a cron task to check wiki.zope.org zope size every minute and restart it if it goes over 350M
- upgraded to Zwiki 0.61
- (tried to) co-subscribe http://wiki.zope.org/WikiZopeOrg and zope-web so I can post updates in one place. I'll stop this if it becomes a problem.
- left the 3 zope threads with cache-size 30000 as-is, for now
