[xwiki-devs] Using an image in a skin in a [[link]]
by Nigel Smith 10 Nov '11

10 Nov '11

Hi guys, I'm trying to write some groovy that uses an image thats in the current skin in a link. In this case its a delete page image, that links to a delete page URL: [[image:${xwiki.getSkinFile('icons/silk/page_delete.gif')}>>${doc.getExternalURL('delete')}]] The issue is that the getSkinFile call returns a relative URL, which ends up getting rendered in the final HTML as <img alt="/xwiki/resources/icons/silk/page_delete.gif" class="wikimodel-freestanding" src="/xwiki/bin/download/Storyboard/fcg9aYKeaI6AVIjxpocO/%2Fxwiki%2Fresources%2Ficons%2Fsilk%2Fpage_delete.gif"></img> Do you have any suggestions for how I can get access to one of the icons for use as an image for a URL? Thanks, Nigel

[xwiki-devs] [VOTE] Upgrade xwiki.org
by Thomas Mortagne 08 Nov '11

08 Nov '11

Hi guys, In order to finish convert extensions.xwiki.org into a valid XWiki Repository server (supported by Extension Manager) I need to put a upgrade xwiki.org and add a jar file (mostly about REST interface). Thing is I need to put the latest 3.3 snapshot version of this REST module so I can see two solutions: * upgrade to 3.2 and patch it with several new API needed by the module * upgrade to latest 3.3 SNAPSHOT pros 3.3 * more simple for me * we can probably quickly come back to the current 3.1.1 if a blocking issue is found until it's fixed * I'm going to quickly update xwiki.org any time we find and fix a blocker issue cons 3.3 * snapshot version on production There is some things I'm not 100% sure: * is there any modification of to the DB introduced in 3.3 not compatible with 3.1.1 and not introduced in 3.2 ? I know id change has not been committed yet +1 for 3.3 SNAPSHOT (ok the pros/cons is a bit oriented ;)) if there is not incompatible DB change -- Thomas Mortagne

[xwiki-devs] Issue modularising groovy code into different pages for different classes
by Nigel Smith 07 Nov '11

07 Nov '11

Hi there I've got two different groovy classes in two different pages (lets say Widget and WidgetFactory), and in a third page I'm trying to call an instance of the WidgetFactory, getting it to create a Widget. I've included the groovy code for both classes in the third page using the "wiki.parseGroovyFromPage(…" call, which works as I can successfully call methods on the widget factory. However, calling the createWidget method on the factory produces an error, in that the WidgetFactory code doesn't know anything about Widgets (i.e. it doesn't know about the Widget class). Am I doing something wrong? I would like to be able to modularise the code in some way. It doesn't matter if there are many different classes declared in the one page, or just one; as long as I can instantiate them, and they know about each other. This would be great as it will mean I can reuse these classes around a few different pages. I've tried including the code using the include macro (outside the groovy block) , and using the xwiki.includeForm call (inside the groovy block), with no success. Thanks, Nigel

[xwiki-devs] Cleaning XWiki XML files for commit
by Ludovic Dubost 07 Nov '11

07 Nov '11

Hi devs, Is there a documentation and a tool to clean XWiki XML files for commit. I used to use the SVN Application to clean the XML and commit in the sandbox for the contributed apps. But the SVN app does not work with git (even with the SVN bridge as it seems svnkit is not compatible), so I'm left to export to commit. How do developers usually do that ?

[xwiki-devs] [proposal] Add TransactionProvider to xwiki-store so FS attachment store can synchronize with main-store without caring what the main store is.
by Caleb James DeLisle 05 Nov '11

05 Nov '11

We need a way for subservient stores such as FS attachments to get transactions from the main store so that it can know to rollback if there is an error in the main store. In order to Cloud/DataNucleus store plug in seamlessly and function with FS attachments, FS attachments needs to be able to get transactions from the main store without knowing or caring what that main store is. I propose this: Add a new storage submodule: xwiki-platform-store-transactionprovider which provides this interface which extends javax.inject.Provider: @ComponentRole public interface XWikiTransactionProvider extends Provider<StartableTransactionRunnable<? extends XWikiTransaction>> { // No additional functions, just the get() from Provider. } The default implementation for now will be a wrapper which picks out the real TransactionProvider based on what the main store is, as defined in xwiki.cfg. This will allow code to get a transaction from the main store then get TransactionRunnables from the main store and use them with this transaction and be assured that you won't be using a Hibernate TransactionRunnable with a Cassandra Transaction. WDYT? Caleb

[xwiki-devs] New indexes in 3.2 created automatically by XWiki
by Ludovic Dubost 05 Nov '11

05 Nov '11

Hi devs, I'm looking at the new indexes created automatically by XWiki now, and they are different than the ones created using the CheckIndexes tool in Admin Tools. First this can make people create doubled indexes which can slow down (a little) writing but what I'm more concerned about is wether the new indexes are good enough. Looking at activitystream_events we have this mysql> show indexes from activitystream_events; +-----------------------+------------+-----------------+--------------+-----------------+-----------+-------------+----------+--------+------+------------+---------+ | Table | Non_unique | Key_name | Seq_in_index | Column_name | Collation | Cardinality | Sub_part | Packed | Null | Index_type | Comment | +-----------------------+------------+-----------------+--------------+-----------------+-----------+-------------+----------+--------+------+------------+---------+ New one | activitystream_events | 0 | PRIMARY | 1 | ase_eventid | A | 2753 | NULL | NULL | | BTREE | | | activitystream_events | 1 | EVENT_TYPE | 1 | ase_type | A | 6 | NULL | NULL | YES | BTREE | | | activitystream_events | 1 | EVENT_PRIORITY | 1 | ase_priority | A | 2 | NULL | NULL | YES | BTREE | | | activitystream_events | 1 | EVENT_WIKI | 1 | ase_wiki | A | 8 | NULL | NULL | YES | BTREE | | | activitystream_events | 1 | EVENT_DATE | 1 | ase_date | A | 2753 | NULL | NULL | YES | BTREE | | | activitystream_events | 1 | EVENT_PAGE | 1 | ase_page | A | 1376 | NULL | NULL | YES | BTREE | | | activitystream_events | 1 | EVENT_USER | 1 | ase_user | A | 8 | NULL | NULL | YES | BTREE | | | activitystream_events | 1 | EVENT_SPACE | 1 | ase_space | A | 29 | NULL | NULL | YES | BTREE | | | activitystream_events | 1 | EVENT_STREAM | 1 | ase_stream | A | 33 | NULL | NULL | YES | BTREE | | | activitystream_events | 1 | EVENT_APP | 1 | ase_application | A | 2 | NULL | NULL | YES | BTREE | | Old ones | activitystream_events | 1 | ase_requestid | 1 | ase_requestid | A | 1376 | 200 | NULL | YES | BTREE | | | activitystream_events | 1 | ase_stream | 1 | ase_stream | A | 35 | NULL | NULL | YES | BTREE | | | activitystream_events | 1 | ase_priority | 1 | ase_priority | A | 2 | NULL | NULL | YES | BTREE | | | activitystream_events | 1 | ase_type | 1 | ase_type | A | 6 | NULL | NULL | YES | BTREE | | | activitystream_events | 1 | ase_application | 1 | ase_application | A | 2 | NULL | NULL | YES | BTREE | | | activitystream_events | 1 | ase_user | 1 | ase_user | A | 8 | NULL | NULL | YES | BTREE | | | activitystream_events | 1 | ase_wiki | 1 | ase_wiki | A | 8 | NULL | NULL | YES | BTREE | | | activitystream_events | 1 | ase_space | 1 | ase_space | A | 29 | NULL | NULL | YES | BTREE | | | activitystream_events | 1 | ase_page | 1 | ase_page | A | 917 | NULL | NULL | YES | BTREE | | | activitystream_events | 1 | ase_param1 | 1 | ase_param1 | A | 1376 | 200 | NULL | YES | BTREE | | | activitystream_events | 1 | ase_param2 | 1 | ase_param2 | A | 44 | 200 | NULL | YES | BTREE | | | activitystream_events | 1 | ase_param3 | 1 | ase_param3 | A | 2 | 200 | NULL | YES | BTREE | | | activitystream_events | 1 | ase_param4 | 1 | ase_param4 | A | 2 | 200 | NULL | YES | BTREE | | | activitystream_events | 1 | ase_param5 | 1 | ase_param5 | A | 2 | 200 | NULL | YES | BTREE | | +-----------------------+------------+-----------------+--------------+-----------------+-----------+-------------+----------+--------+------+------------+---------+ 24 rows in set (0.01 sec) The xwikiattrecyclebin has no new indexes, and I have had a case of performance issue with the recyclebin because of indexes. Who have worked on this and how has it been reviewed wether or not this was enough ?

[xwiki-devs] [Proposal] Standardize on Commons Lang3 HashCodeBuilder and EqualsBuilder for hashcode/equals implementation
by Vincent Massol 05 Nov '11

05 Nov '11

Hi devs, WDYT about standardizing on Commons Lang3 HashCodeBuilder and EqualsBuilder for hashcode/equals implementation? http://commons.apache.org/lang/api/org/apache/commons/lang3/builder/HashCod… http://commons.apache.org/lang/api/org/apache/commons/lang3/builder/EqualsB… So far I've used manual code from http://www.technofundo.com/tech/java/equalhash.html but I think standardizing on Commons Lang is better for the following reasons: * a lot of less code to write * less prone to exploding cyclomatic complexity and thus checkstyle erros There might be some extreme cases where we don't want to add a new dependency (like for some libraries potentially) but these should be exceptions. If we agree I'll document it on dev.xwiki.org in the best practice section. Thanks -Vincent

[xwiki-devs] [VOTE] Add new LinkChecker modules in xwiki-platform
by Vincent Massol 03 Nov '11

03 Nov '11

Hi devs, I'd like to create the following modules in xwiki-platform to add a UI for the linkchecker feature: xwiki-platform-linkchecker/ |_ xwiki-platform-linkchecker-ui/ |_ xwiki-platform-linkchecker-refresher/ where: * xwiki-platform-linkchecker-ui/ will add a Tab in Main.AllDocs to list broken external links. It'll contain the livetable that you can see on http://www.xwiki.org/xwiki/bin/view/Admin/ExternalLinkStatus * xwiki-platform-linkchecker-refresher/ will contain an EventListener listening to DocumentUpdatingEvent and remove all link states from the link state cache for the modified pages received as Events. This module will depend on the LinkChecker Transformation module located in xwiki-rendering. Here's my +1 Thanks -Vincent

[xwiki-devs] About the AdminTools extension
by Maxime Sinclair 02 Nov '11

02 Nov '11

Hello Devs, As a XWiki admin, I installed the AdminTools extension (http://extensions.xwiki.org/xwiki/bin/view/Extension/AdminTools) The configuration check pages are very useful to verify a fresh install, the export pages are priceless (especially the Admin.Export one)... Of course, these pages are not very polished but they do the job. Fortunately, this extension is maintained as a contribution in Github. In the extension wiki, it would be fine to clearly mention that "Import Export Application", "Monitoring Application", "XAR Diff Application" are now included in the AdminTools (as it is for the "Check Config And Indexes Application"). Maybe I miss one or two. If you agree, I can do it. By the way, I submitted a few days ago a pull request to add a new ShrinkTrashBin page in AdminTools. Don't forget it. Maxime
