Item10664: Having trouble getting MongoDB to notice newly created webs - i.e. it seems I have to explicitly load a web before the DB gets created for it

I'd love a less vague description, but I'm assuming that you mean you create a new web via the Func api?

and I'm hoping that your listeners are functioning correctly....

When I use the ManagingWebs UI to create a web, Eg. Sandbox.TestWeb, it times out and fcgid kills the process (returns error 500 to the browser).

Watching top, I can see memory usage grow and grow up to 1GB before the fcgid timeout kills it off.

My LocalSite.cfg contained the following:

$Foswiki::cfg{Store}{Implementation} = 'Foswiki::Store::RcsWrap';
$Foswiki::cfg{Store}{SearchAlgorithm} = 'Foswiki::Store::SearchAlgorithms::Forking';
$Foswiki::cfg{Store}{EgrepCmd} = '/bin/grep -E %CS{|-i}% %DET{|-l}% -H -- %TOKEN|U% %FILES|F%';
$Foswiki::cfg{Store}{FgrepCmd} = '/bin/grep -F %CS{|-i}% %DET{|-l}% -H -- %TOKEN|U% %FILES|F%';
$Foswiki::cfg{Store}{QueryAlgorithm} = 'Foswiki::Store::QueryAlgorithms::BruteForce';
$Foswiki::cfg{Store}{PrefsBackend} = 'Foswiki::Prefs::TopicRAM';
$Foswiki::cfg{Store}{Listeners} = {'Foswiki::Plugins::MongoDBPlugin::Listener' => 1};
$Foswiki::cfg{Plugins}{MongoDBPlugin}{Enabled} = 1;
$Foswiki::cfg{Plugins}{MongoDBPlugin}{Module} = 'Foswiki::Plugins::MongoDBPlugin';
$Foswiki::cfg{MongoDBPlugin}{host} = 'a.wiki.org:27017,b.wiki.org:27017,c.wiki.org:27017';
$Foswiki::cfg{MongoDBPlugin}{auto_reconnect} = 1;
$Foswiki::cfg{MongoDBPlugin}{auto_connect} = 1;
$Foswiki::cfg{MongoDBPlugin}{timeout} = 20000;
$Foswiki::cfg{MongoDBPlugin}{find_master} = 1;
$Foswiki::cfg{MongoDBPlugin}{w} = 1;
$Foswiki::cfg{MongoDBPlugin}{wtimeout} = 1000;
$Foswiki::cfg{MongoDBPlugin}{username} = '';
$Foswiki::cfg{MongoDBPlugin}{password} = '';
$Foswiki::cfg{Plugins}{MongoDBPlugin}{ExperimentalCode} = 1;

Please note the "use of unitialised..." errors in the apache error log.

Hrm. After setting Search & QueryAlgorith to MongODB (rather than Forking/!BruteForce), the create web function now works. The memory usage is still somewhat concerning, but I might also throw in:

• I was hitting 'back' and re-submitting the create new web page, so maybe it was struggling in the code which generates an CSRF validation error?
• What kind of search happens when you create a new web - maybe this occurs on our configuration & webs with Forking/BruteForce because they are too slow?

Anyway, apart from the above glitch, it seems my problem was caused by incorrect listener config. It works now.

so can we close it? wrt csrf, no idea, er, nope, noidea

Let's close it
