[OpenGuides-Dev] OG performance
by Paul Makepeace 20 Jun '07

20 Jun '07

Hi, I don't follow OG development but as host operator a few things are coming up. The machine's load is gradually climbing over time and some of that is OG. Despite a relatively low hit rate on OG it is consuming quite a bit of resource. If OG started taking off it would take the machine down. First up: index.cgi requires 0.35s to perform a `perl -c` syntax check. Any thoughts on putting OG on a mod_perl server? I have mod_perl running here of course and we'd need to coordinate some apache.conf stuff. Second: the supersearch.cgi gulps down CPU, often for seconds at a time. It is a frequent resident of `top` output. This isn't really acceptable. I'm going to request this feature be turned off unless an effective optimisation plan or some other way to reduce its impact here is constructed pretty soon. Sorry about this but it's encroaching on others. Third: I wonder if there's some way to instruct robots not to spider parts of your wiki. This ought to speak for itself: $ grep crawl /var/log/apache/london.openguides.org-access.log | grep 'action=edit' | wc -l 8242 $ Finally: I posted about a DoS and was wondering what the status of a solution was. http://openguides.org/mail/openguides-dev/2004-October/000542.html Cheers, Paul (any overbearing tone unintentional ;-) -- Paul Makepeace .............................. http://paulm.com/inchoate/ "If my elbow was straight, then I'll show oyu mine!" -- http://paulm.com/toys/surrealism/

Saint Paul patches
by Chris Prather 24 Dec '06

24 Dec '06

Hi, I'd done some patching to St. Paul and wanted to feed hte changes back. Tickets #154 and #155 in the Trac (http://dev.openguides.org) are both from work I'd done previously with St. Paul's guide. #154 provides basic JSON support for nodes and indexes. The Wiki::Toolkit::Plugin::JSON uses either JSON.pm or JSON::Syck to produce the output. #155 provides a 404 script for when things go away. St. Paul had some problems with incosistant URLs in the past and I noticed that 404s were very large because of this, so I wrote a little CGI to try to help you can see it in action by going to http://saintpaul.openguides.org/Pino's_Pizza ... it will suggest the right URL for the guide, or possibly a Search. I've cleaned up the script so that it does everything in a generic fashion and should integreate cleaner with other people's templates etc. (Originally I was just dumping HTML but I went and made a template now.) I hope people find these useful. :) -Chris

Guide Map prototype, if your interested
by Rich 30 Nov '06

30 Nov '06

Hello! For my university (manchester, UK) I started a map / wiki interface for students to make a geographical guide for other students to POI's like bars, shops, etc. The code started as GMaps code, and at the moment I'm transferring it over to OpenLayers and eventually OSM support. You can see it at [1] See [2] for a brief description of the functionality and various views you can do. (don't miss the Edit pane accessed from the top left). The map there is a bit buggy, i've improved it since, but not updated the live version. Everything's fairly object orientated, so maintaining/extending/adapting it should be easy. Very brief features: *In the split screen view clicking on a marker shows you the relevent page in the wiki panel of the page. *Users can add, edit, move, delete markers. *Map view can be filtered using collapsable checkbox tree to show/hide catagories. *Catagories can be edited by users. *There is a change list of all changes made by users (see Recent Changes link on Edit view) *If users are logged into the adjoining Wiki, any edits by them on the map are recorded as by them (and if you want to restrict edit access to only logged in/certain users, you can do that) This isn't the best solution possible, and depending on how much OG will interact with OSM, it will need to be adapted heavily. I don't know what the OSM guys have thought of along these lines, but just telling you in case your interested! I'm going to try and come to the OSM/OG meetup in Oxford (Starting a new job the weekend before though). A few licensing issues for it; The checkbox code is from blueshoes.org, and free licensed for non-commercial use, but not distribution [3]. I couldn't find any F/OSS checkbox tree code, it looks like Dojo might have a f/oss solution [4] now though with an extension to their tree widget. (I'll code this in if you guys are interested). I got a few tips from various gmaps tutorial websites, I'll need to go back and check their licenses (may of been cc-by-sa). I could code it all again myself now (and will if i need to), having learnt the facts from them. I'm note sure of the legal situation.

Wiki thing *like* an OpenGuide
by Daniel MacKay 28 Nov '06

Hi! I'm the promoter for an Oddmuse wiki which is used very similarly to OpenGuide; is there any way to get listed with your system? My wiki is a guide to gay and lesbian culture in Halifax, Nova Scotia, Canada, http://gay.hfxns.org/ -- Daniel MacKay Halifax, Nova Scotia, Canada

[bug] last_modified not containing epoch
by Paul Makepeace 23 Nov '06

23 Nov '06

Here's the output of a ./Build test after various fixes. There is some warning about a string comparison happening where it's expecting an integer. My guess is some back-end store is returning a formatted date rather than an epoch time. http://scsys.co.uk:8001/4743 Argument "\x{32}\x{30}..." isn't numeric in numeric lt (<) at /home/www/paulm/openguides-trunk/blib/lib/OpenGuides/Feed.pm line 169. Argument "2006-10-28 19:02:59" isn't numeric in numeric lt (<) at /home/www/paulm/openguides-trunk/blib/lib/OpenGuides/Feed.pm line 169. ("\x{32}\x{30}..." is "20...") This IMO really should be a failure via an assertion further back up the stack. Looking at the Wiki::Toolkit pages the closest the format of last_modified gets to being specified is as a "timestamp". (So the bug is that it's not really nailed down.) There's a bunch of XML issues in the paste someone might have thoughts on too. Paul

force_wgs84, Helmert & deps
by Paul Makepeace 23 Nov '06

23 Nov '06

I currently have t/53 failing due to WGS84 coords not being calculated. I traced this back to Geo::HelmertTransform failing due to it not being installed. I was going to patch this but wanted to check first. My initial thought was if the force_wgs84 param is set to 0 (no) during perl Build.PL then the Geo::HelmertTransform requirement should be added to the build requires section. Something ditto for Geography::NationalGrid::(IE|GB). What say ye? Also, I'd like to see $@ tested after the transformation; I have that as a die in my local source right now. It's at the least irritating having silent failures requiring source spelunking. As an aside it made me wonder whether force_wgs84 = 1 is a more appropriate default given that it doesn't seem to matter much, and it's an optimisation away from performing the transform. I really havent looked at the code all that much though so this might not be a sensible comment. I have a few other random patches against trunk sitting here; who'd like 'em? Paul

Website now under version control
by Earle Martin 23 Nov '06

23 Nov '06

The openguides.org website is now running out of the OpenGuides svn repository, so anybody with a commit bit can update it. Hopefully the structure should be easy enough to understand. The only thing that you need to do after committing a change is to poke me, as I'll have to do an "svn up" on my webserver. This is exponentially easier than getting changes done was before ;) Hope this is useful, Earle. -- Earle Martin http://downlode.org/ http://purl.org/net/earlemartin/

Wiki::Toolkit::Plugin::Summariser
by Chris Prather 12 Nov '06

12 Nov '06

Boston's dropdown lists in edit_form.tt generated all the excitement in Hex on IRC. I've updated the plugin so that it works with Wiki::Toolkit (really not very hard). Hex has a patch he's sending to Dom to make all of this obsolete, but I figured I'd post this for posterity at the least, and incase it's useful in general. -Chris
