[xwiki-devs] How list objects?
by Julio Brum 11 Jul '16

11 Jul '16

Hi, I need to list events that were inserted through the MoccaCalendar application. I need to get the title, the way, the start date and the end date of the event. I need to get only the future events (> = today) and a maximum of 10 events. Unfortunately I could not do, so I ask your help. I could only do just that: #set($results = $xwiki.search("select doc.title, doc.web, doc.fullName from XWikiDocument doc where doc.space = 'MoccaCalendar. Mycalendar' and doc.fullName != 'MoccaCalendar. Mycalendar.WebHome' ")) #foreach ($item in $results) [[$item.get(0)>>doc:$item.get(2)]] #end Thank you in advance, Best Regards, Julio

[xwiki-devs] [NOTICE] Tomcat versions that are not working anymore with XWiki
by Vincent Massol 11 Jul '16

11 Jul '16

Hi everyone, The Tomcat project has brought a change in the way they handle RequestDispatcher (see https://bz.apache.org/bugzilla/show_bug.cgi?id=59317) which is causing regressions. Thus for the moment you should **not** use the following Tomcat versions: • 9.0.x for 9.0.0.M5 onwards • 8.5.x for 8.5.1 onwards • 8.0.x for 8.0.34 onwards • 7.0.x for 7.0.70 onwards (See also http://jira.xwiki.org/browse/XWIKI-13556 for more details) I’ve also added a warning on: http://platform.xwiki.org/xwiki/bin/view/AdminGuide/InstallationTomcat Thanks -Vincent

[xwiki-devs] [Brainstorming] Alternative to Rendering Transformations
by Vincent Massol 07 Jul '16

07 Jul '16

Hi devs, Rendering Tx are great to modify an XDOM into another XDOM. However they have a limitation: they’re slow (since you have to traverse the whole AST). So if you have 10 Tx, you traverse the AST 10 times… I’d like to brainstorm about an alternative: the ability to register some Listener that will get executed at render time and that will transform the events. Use cases ======== Here are some example of Tx that would benefit being rewritten using this mechanism: * Icon Tx * Auto linking of JIRA id to jira issues * WikiWord Tx Implementation ============= It could be something like: * Introduce a ConfigurableBlockRenderer interface with a addListener() method * Modify AbstractBlockRenderer to execute those Listeners before it calls its PrintRenderer. This can be achieved with a composite listener that wraps the listeners added and the PrintRenderer. * Have a way to register some Listeners in the configuration, that should be executed when a page is rendered * Modify XWikiDocument so that those configured listeners are executed when rendering a page Differences between Tx and Listeners ============================== * Tx are slow but easy to write since you have access to the whole AST * Listeners are harder to write since you need to store the events if you need to remember them (but we have developed some tools already over the years such as the LookaheadListener) * Listeners depend on their order and they should be written carefully to minimize their interdependencies * Listener will get executed only at render time so you need to render to get the modifications to the tree, while Tx are independent of rendering. WDYT? Do you see a better way to achieve the same goal (ie removing the Tx performance limitation)? Thanks -Vincent

[xwiki-devs] [Brainstorming] Changing the Mail configuration algorithm?
by Vincent Massol 06 Jul '16

06 Jul '16

Hi devs, I’m working on http://jira.xwiki.org/browse/XWIKI-13546 ("Error in the log when sending a mail through the Mail API”). One way to fix it would to always look for the Mail.Config page in the main wiki instead of in the current wiki. Actually the current algorithm is the following when looking up a mail configuration property: * <ul> * <li>Look in Mail.MailConfig in the current wiki</li> * <li>[Backward compatibility] Look in (current space).XWikiPreferences in the current wiki</li> * <li>[Backward compatibility] Look in XWiki.XWikiPreferences in the current wiki</li> * <li>Look in the xwiki properties file</li> * </ul> We also need to implement http://jira.xwiki.org/browse/XWIKI-12435 (“Use the Main Wiki Mail Configuration if not overridden at the subwiki level”): “ Right now when sending a mail in a subwiki, the configuration is taken from that subwiki's Mail.MailConfig document. In a non-farm use case, it's a pain to have to configure SMTP settings for each subwiki. It would be better to look into the main wiki's mail configuration when there's no overridden config at the subwiki's level. " So I can see 2 options. Option 1: Drop support for looking for configuration in subwikis ======== * Rationale: there are few use cases that require overriding the mail config in a subwiki * Potential issue: if we stop looking for *.XWikiPreferences or for <current wiki>:Mail.Config then we won’t migrate configurations but always use the config from the main wiki. So backward compat is theoretically broken. * But it’s likely that the config in subwikis is the same as the config from the main wiki anyway. It’s also likely that if a subwikis smtp server is configured, then the main wiki is also configured. So it could be acceptable with a message in the Release Notes. Option 2: Continue supporting overriding in subwikis ======== * Stop bundling Mail.Config for subwikis and modify the config algorithm to be: * <ul> * <li>Look in Mail.MailConfig in the current wiki</li> * <li>[Backward compatibility] Look in (current space).XWikiPreferences in the current wiki</li> * <li>[Backward compatibility] Look in XWiki.XWikiPreferences in the current wiki</li> * <li>Look in Mail.MailConfig in the main wiki</li> * <li>Look in the xwiki properties file</li> * </ul> I’ve discussed it quickly with Denis who prefers option 1 since he even sees the ability to configure the smtp server at the wiki level a potential issue (bypassing the farm admin). Personally I’m hesitating and I’d hate to remove the local override and then find some use cases where we need it. WDYT? Thanks -Vincent

[xwiki-devs] [Proposal] Make it simpler for users to install extensions offline
by Vincent Massol 04 Jul '16

04 Jul '16

Hi, I’d like to propose that we add a new extension repo location by default in xwiki.properties that points to a predefined location in the permanent directory. For example: PERMDIR/extension/custom or PERMDIR/repository We’d have a README file in there that could explain what this directory is for with a small command line example: mvn org.apache.maven.plugins:maven-dependency-plugin:2.1:get \ -DrepoUrl=url \ -Dartifact=groupId:artifactId:version \ -Dmaven.repo.local=/location/to/custom/repo This new repo would be the last one in the list of repos in xwiki.properties. WDYT? Thanks -Vincent
