[xwiki-devs] [GSOC] Distributed Search status and problem committing the source code
by saikrishna venkata pendyala 10 Jul '08

10 Jul '08

Hi David and Ludovic, I have finished implementing distributed search for XWiki using the existing plugin "lucene". In short what the new code does. (on each individual installation) 1. As soon is XWiki is started, lucene plugin is initiated, during the process of initialization, the machine makes is index remote available. 2. A Parallel searcher is created over all the remotely available indexes, during the initialization of lucene plugin. These 2 steps will achieve a simple distributed search. But Index updates would not be reflected. 3. As and when there is an index update, index reader which was made remotely available earlier in step 1 is re-opened and is made remotely available. With this Index updates on remote machines are reflected in search process. But what if one the machines go down during the process ?? 4. When ever there is an error while performing distributed search, the parallel searcher in step 2 is redefined, i.e instead of searching 'n' machines (earlier) it will search only 'n-m' machines. At some point the machines went down will be started again. How to search on these machines again? 5. A thread keeps on checking if searcher is set to search over all the slaves defined in xwiki.cfg or not . If it is not searching on all the slaves, It will try to redefine the searcher in step 2 as did in step 4. 6. I have modified existing XWiki.Results to make compatible to both distributed/normal search. 7. Modified xwiki.cfg.vm, to have fews options for distributed search. I have tested this on a cluster of 5 machines and it is working fine. In addition to distributed search I have also attempted to fix 2 bugs/issues in earlier implementation of lucene. a. Fix Lucene plugin scoring algorithm -- *XPLUCENE-8<http://jira.xwiki.org/jira/browse/XPLUCENE-8> *b. Remove duplicates from Lucene search results -- *XPLUCENE-5<http://jira.xwiki.org/jira/browse/XPLUCENE-5> *All these changes exist in the modified version of lucene plugin. *Cannot commit the source code : *I was trying to commit the source code to https://svn.xwiki.org/svnroot/sandbox/plugins/lucene, but I couldn't This is what I did, 1. svn co https://[email protected]/svnroot/sandbox/plugins/~/xwiki-sandbox-… 2. svn export lucene ~/xwiki-sandbox-plugins 3. cd ~/xwiki-sandbox-plugins 4. svn add lucene 5. svn commit --username pvsaikrishna -m 'distributed search using lucene' *I got the following error* svn: Commit failed (details follow): svn: MKACTIVITY of '/svnroot/sandbox/!svn/act/e5cbc51c-1643-4805-9019-0ce92d036d2b': 500 Internal Server Error (https://svn.xwiki.org) --Sai Krishna

LANG property in startup script in standalone version
by Vincent Massol 10 Jul '08

10 Jul '08

Hi, Does anyone know why we have the following LANG property defined in our startup scripts: #!/bin/sh export LANG=fr_FR.ISO8859-1 JETTY_HOME=. JETTY_PORT=8080 JAVA_OPTS=-Xmx300m java $JAVA_OPTS -Dfile.encoding=iso-8859-1 -Djetty.port=$JETTY_PORT - Djetty.home=$JETTY_HOME -jar $JETTY_HOME/start.jar I think this is bad as it's french and I don't think we should set it for the user. That said, if it's there its probably because it was required in the past, hence my question here. To summarize: anyone sees any issue if I remove that "export LANG" line? Thanks -Vincent

[xwiki-devs] [VOTE] Bring forward XE 1.5 final + create 1.5 branch
by Jean-Vincent Drean 09 Jul '08

09 Jul '08

I'd like to bring forward the release dates for XE 1.5 final, as follows: * 1.5RC1 - 07/07 * 1.5Final - 15/07 I'd also like to create a branch for 1.5 since it's now in RC stage and trunk will become 1.6-SNAPSHOT so that committers eager to work on 1.6 can start doing so and so that we're not tempted to push non bug changes in 1.5. Reasons: * Some of us would like to work on 1.6 (like Jerome who'd like to fix our captcha mechanisms) * There's an ongoing vote to drop the 1.3 branch, as usual we'd have 2 branches with 1.4 and 1.5 (our standard rule is to support 2 versions). Here's my +1 to both the new dates and the branch creation. Thanks, JV.

[xwiki-devs] Parser Issuer
by malaka ekanayake 09 Jul '08

09 Jul '08

Hi vincent Now I'm working on the costume implementation of the IDocument Partitioner which uses the XDOM parser. But in order to to register partitions with the IDocument,requires the offset and the length of each token returned by the parser. But the current implementation of the parser don't have that information.Do I need to look at that issuer as well or what? I have very little understanding of the implementation of the parser and I will be difficult for me to implement that functionality. Vincent can you help me on this issuer. -- Malaka Ekanayake CSE UOM

[xwiki-devs] Unicode font problem
by Sergiu Dumitriu 08 Jul '08

08 Jul '08

Hi devs, I almost finished implementing http://jira.xwiki.org/jira/browse/XWIKI-1609 What remains to be done, is to find a good font to embed in XWiki. The best candidate would be the one from the StixFonts project, but that one is not yet released (delayed several years, now apparently is in the packaging stage; the expected date is August, but given the history of their release dates, it's more likely sometime in the winter or even next year). The next best candidate is FreeFont (http://savannah.gnu.org/projects/freefont/) but that one is GPL, and doesn't have complete support for asian characters. The third best candidate is an extended version of Computer Modern (http://canopus.iacp.dvo.ru/~panov/cm-unicode/) which is distributed under the X11 license, but it is less complete than FreeFont. For the moment, I'd be in favor of including the FreeFont, but we need to see if a GPL font can be redistributed or not, and maybe ask for permission to include it. WDYT? -- Sergiu Dumitriu http://purl.org/net/sergiu/

[xwiki-devs] [GSoC]Try the Office Importer Plugin
by Wang Ning 08 Jul '08

08 Jul '08

Hi Vincent & all, I finish the clean of the plugin code and write a simple user manual. You can see it in http://dev.xwiki.org/xwiki/bin/view/Design/OfficeImporter#HQuickStart. All files needed for this plugin can be found in that page http://dev.xwiki.org/xwiki/bin/view/Design/OfficeImporter, except the openoffice install . Please give some feedback after try the plugin. Any feedback will be very appreciated. This plugin is very initial. It only put out the html code , not xwiki syntax, because the html code to xwiki syntax conversion should be done by XHTMLParser which is not ready yet. Open question: Now the plugin can handle the file which is uploaded to xwiki as a attachment. Do you think it's necessary that the office importer would have the upload feature itself or should provide a XWikiAction something like "bin/importer/Main/page"? Now the plugin can work. However it's a little complicate. If you want to convert a office document 1. you first upload the document 2. copy the attachment name(because the name of document change after upload) 3. edit the page and add the velocity code to use the importer plugin 4. save and view. I think it should be more simple. WDYT -- Sincerely, Wang Ning
