Extension talk:EzMwLucene

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)

Search does not return all results
Search for "Android" you expect to see all Android.*. But it only returns Android.NPE.

Search for "javadoc" you expect to see "javadoc.url". But it doesn't get any result. If search for the whole word of "javadoc.url", it can get the result expected.

It seems that partial word search for any word with dot is not working well.

Is it a known bug, or a configuration I can change?

Problem with Searching Japanese Characters
If I search Japanese characters, I always get "No page text matches" even though the pages exist.

If one of the Search results (by searching English words) contains Japanese characters, they all show as question marks (?????????).

Is this a bug, or a problem of my configuration? Any idea would be greatly appreciated.

Searching for an empty string

workaround

This can be overcome by adding the following code to extensions/EzMwLucene/EzMwLuceneSearchEngine, just inside the searchText method (before any other code). I am not good with diff, if someone can make a real patch to illustrate this, it may be helpful. if (empty($term)){ wfDebugLog('EzMwLucene', "SearchEngine::searchText: term is empty, returning a blank result set"); return new EzMwLuceneSearchResultSet(false); }

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


 * Thanks! This method also fixes my warning messages below on the Special:Search page.

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)

Special:Upload broken on new install


This can be fixed by applying the following patch:

--- EzMwLuceneIndexer.php.old  2009-05-08 16:26:28.000000000 -0500 +++ EzMwLuceneIndexer.php      2009-05-08 16:26:00.000000000 -0500 @@ -38,7 +38,7 @@              $xml .= " <![CDATA[{$revision->getRawText}]]> "; /* If the article is in the Image namespace, add the file url */ if ($article->getTitle->getNamespace==6) { -                      $file =  wfFindFile($article->getTitle); +                      $file = wfFindFile($article->getTitle,false,0,true); $xml .= " <![CDATA[{$file->getFullUrl}]]> "; }              $xml .= ' ';


 * Indead of applying the "patch" with some command like "$ patchphp EzMwLuceneIndexer.php < the_code_above.php", I just simply edited the EzMwLuceneIndexer.php file, and replace the single line of "-" with the line of "+".
 * It works!

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/ and paste the following code (I hope this is correct, since I'm not a Debian guru):
