= Alterego's bugs = These are the bugs I've found with this extension using Kubuntu Jaunty Jackal and MediaWiki 1.16alpha (r50407) --Alterego 00:31, 10 May 2009 (UTC)

Loading Special:Search
The following error is repeated 25 times after first loading Special:Search (searches do work, however)



This can be supressed by setting

error_reporting = E_COMPILE_ERROR|E_ERROR|E_CORE_ERROR

in php.ini

Distribution does not include README/INSTALL files
The documentation for this distribution should be included in the package itself, not just on SourceForge which is extremely inconvenient. http://sourceforge.net/docman/display_doc.php?docid=179038&group_id=254413


 * It also be acceptable to put the documentation on this wiki page, and have the README link here. It would be really nice to have everything hosted in wikimedia's svn. --Ryan lane 14:43, 11 May 2009 (UTC)

This can be fixed by applying the following patch:

Extension is mispackaged
The correct way to pack a tarball is such that when you unpack it, it contains the following directory structure: EzMwLucene_1.0/ client/ server/ It is rude to put client and server at the top level of the package.

service.sh always fails (with FAIL)
Running $RUN_CMD from the command-line directly, and then backgrounding it and disowning it, works just fine. That bash script you borrowed from another software package simply does not work on my OS, however. The shell script looks portable and expertly written; nontheless it depends on subtle run conditions that are not easy to debug and do not appear to be useful. Modern linux operating systems do not need a shell script to start/stop/restart processes - that is a job for the system to handle. I start the process in the following way. Note that after the long java command comes  This tells bash to background the process and disown it. You should put that in a file in /etc/init.d so that it gets started with your system.

 * service.sh really should report success or failure in its output. It does put error messages into the error log though. I got this working by doing the following:
 * Made a lucene user/group for the system, with the lucene user having a shell of /bin/bash and a home directory of /apps/lucene/home/lucene (ownership lucene:lucene 600)
 * I put the server directory at: /apps/lucene/server (ownership of files/directories is root:root, except for ezmwlucene.properties which is root:lucene; everything is world readable except for ezmwlucene.properties, which is 640)
 * I set the following variables in service.sh:
 * EZMWLUCENE_HOME="/apps/lucene/server"
 * EZMWLUCENE_LOG="/apps/lucene/home/lucene/ezmwlucene.log"
 * EZMWLUCENE_USER="lucene"
 * I installed java 1.6 instead of 1.5
 * I created /data/lucene (ownership lucene:lucene 600)
 * In ezmwlucene.properties, I set the following (notice I didn't specify a port for the database url, this tells it to use a socket):
 * lucene.index = /data/lucene/index
 * server.port = 8080
 * mediawiki.name = 
 * mediawiki.databaseUrl = jdbc:mysql://localhost/
 * mediawiki.databaseUser =
 * mediawiki.databasePassword =
 * mediawiki.imagesUrl = https://fully.qualified.servername/wiki/images/
 * mediawiki.localImagesUrl = file:///data/wiki/images/
 * I ensured that the lucene user could read /data/wiki/images and all images below (my permissions are fairly strict)
 * setfacl -R -d -m user:lucene:rX /data/wiki/images
 * setfacl -R -m user:lucene:rX /data/wiki/images
 * I ensured that I could pull images from https://fully.qualified.servername/wiki/images/:
 * curl -k "https://fully.qualified.servername/wiki/images/5/58/Test.pdf"
 * I put the following into LocalSettings.php:
 * $wgEzMwLuceneQueryUrl = 'http://localhost:8080/query';
 * $wgEzMwLuceneIndexUrl = 'http://localhost:8080/index';
 * $wgSearchType = 'EzMwLuceneSearchEngine';
 * require_once("extensions/EzMwLucene/EzMwLucene.php");
 * $wgDebugLogGroups["EzMwLucene"] = "/tmp/ezmwlucene.log";
 * I applied the patch to EzMwLuceneIndexer.php, as listed in one of the comments above


 * After doing the above, I started service.sh (check /apps/lucene/home/lucene/ezmwlucene.log for errors to ensure it started properly, and check netstat to ensure it is actually running). Then I started uploading pdfs and docs and such to test with. Check /tmp/ezmwlucene.log, /apps/lucene/home/lucene/ezmwlucene.log, and your web server logs to ensure that updates are being sent to the daemon, the daemon can pull URLs from the web server, and that the daemon is successfully accessing the files.

Uploading a new pdf does not cause it to get indexed
When I ran loader.sh there was a pdf on the wiki with the title: "Family history of heart attack as an independent predictor of death due to cardiovascular disease". Searching for this title returned the pdf. I then proceeded to delete the pdf, which deleted it from the index. I then re-uploaded it again which did not cause it to show up again in the index.


 * This worked for me, but it wasn't exactly easy to get it working. Check your logs througoughly. --Ryan lane 14:44, 11 May 2009 (UTC)

files are not searched by default
It appears that every single user will have to set their preferences to search the file namespace. $wgNamespacesToBeSearchedDefault = array(   NS_MAIN => true,    NS_FILE => true, ); This is from the MW FAQ but it doesn't actually work.. This did work for all users however:

UPDATE user SET user_options = REPLACE(user_options, 'searchNs14=0', 'searchNs14=1');

Unfortunately, while this changes the preference it does not cause the File namespace to be actually searched

Here's an IRC log on this issue which suggests upgrading past 48811 might help:

this seems to have no effect whatsoever on my wiki! http://www.mediawiki.org/wiki/Manual:$wgNamespacesToBeSearchedDefault i even set NS_MAIN => false it still searches main! what version? 48811 search preferences don't seem to matter either long story huh, i just tested that it works on Wikipedia. wtf but the short answer is that changes to preference defaults will only apply to existing users after r48811 I fixed the bug myself lol ok, i guess i'll upgrade a revision? i try to stay in sync w/ WP you'll need to upgrade a few revisions
 * Rdsmith4 has quit (".")

Indeed - upgrading to MediaWiki trunk in addition to using $wgNamespacesToBeSearchedDefault works.

PDF logo is pointless!

 * When combined with the PDF handler, is it possible that this is less pointless? --Ryan lane 13:37, 11 May 2009 (UTC)
