Re: [xwiki-users] Bug with file storage ?
Hi,
Thank you for the help.
I checked the xwiki.cfg (release 4.0): the property xwiki.work.dir is not
commented as deprecated.

Hi,
Because of memory problems with our (small) server, I've decided to
switch from hibernate storage to file storage for attachments.
When I launch the filesystemAttachmentPorterScript-2.0.xwiki20 groovy
script, the script prints :
This is your storage directory, when filesystem attachments are enabled
you have to back this up as part of your data backup routine.
/usr/apache-tomcat-5.5.25/logs/data/storage
The value is the result of
Utils.getComponent(FilesystemStoreTools.class).storageDir.getAbsolutePa
th() command (tomcat was started from logs directory).
The xwiki doc says :
The directory in which the attachments are stored in the filesystem is
defined with the parameter xwiki.work.dir in the xwiki.cfg file.
But the value in my xwiki.cfg is :
xwiki.work.dir=/usr/apache-tomcat-5.5.25/webapps/xem/work
If I try the command below in a groovy script, the value is what I want,
but not the value
Utils.getComponent(FilesystemStoreTools.class).storageDir.getAbsolutePa
th() prints :
xwiki.getXWiki().getConfig().getProperty('xwiki.work.dir') =
/usr/apache-tomcat-5.5.25/webapps/xem/work
It seems to me that the value of xwiki.work.dir is not used, only the
default value.
That's a bug ?
Not really. xwiki.work.dir is deprecated, and the configuration since
XWiki 3.5 is taken from the environment.permanentDirectory setting in
xwiki.properties. I updated
http://platform.xwiki.org/xwiki/bin/view/AdminGuide/Attachments with the
new way to configure this.

[xwiki-users] Fetch application fields from other applications
Hi, I have created two applications, let's say one for managing clients and one for managing projects. How can I fetch the clients name and use it in my list of projects? To speak in database terms I want my project's table to have a foreign key which refers to the client primary key so that I can access all client's attributes.

The main advantage of multi-tenancy is performance optimization. Problem: The main wiki has a relative good level of performance - with a response time around 2.5 second to browse a page So we are in the xwiki database But when we are in a virtual wiki (another schema ) - the performance are very poor. The average response time is around 5 seconds per page !!! So at list 2 times slower. We are using MySQL and glassfish 3.1 - and we have done tuning on the MySQL database and glassfish. We have used a profiling tool and see that the request send to the virtual environment are raising a big amount of exception ... The problem is not on the database part (even if they are many SQL calls to visualize only one page) The problem seems really to be on the virtual environment configuration OR in a file corruption ... I have attached the exception list . (exception_list.xls) From this is it possible to know if we have an installation issue ?? Does someone have experience of very good performance with xwiki ? ( response time #1second per page) In that case I can tell you fore sure that there's no performance issue with multiwikis. Each wiki has its own DBs so it's really fast. Maybe you don't have indexes set on the subwikis?

Each application has a class that describes the type of data managed
by the application (the client class and the project class in your
case). By default a live table can display information taken from the
instances of a single class. If you want a live table that aggregates
('join' in database language) data from instances of multiple classes
then you have to write a custom live table results page. Live tables
are fed with JSON generated by a wiki page. By default this page is
XWiki.LiveTableResults but you can create your own results page. It's
not trivial though..

thanks in advance,

Well, it seems that the space index macro has a hard-coded ordering on
the creation date. You can change that in the source code of the macro:
- edit Main.SpaceIndex in the object editor
/xwiki/bin/edit/Main/SpaceIndex?editor=objectclassname=XWiki.WikiMacroClass
- in the Macro code field of the XWiki.WikiMacroClass object, find the
line:
#set ($docNames = $xwiki.searchDocuments('where doc.space=? order by
doc.creationDate desc', $limit, 0, [${spaceParam}]))
and replace it with:
#set ($docNames = $xwiki.searchDocuments('where doc.space=? order by
doc.name', $limit, 0, [${spaceParam}]))
- save, and it should order by name now.

True, the two settings (in xwiki.cfg and in xwiki.properties) co-existed
for some time, and different modules were gradually updated to use the
new setting instead of the old one. I just looked at all the code and it
seems that the old setting is still used by the Lucene plugin. After
fixing that one, it would be possible to fully deprecate the old setting.
