[xwiki-devs] [VOTE] Creation of xwiki-platform-uiextension module

by Vincent Massol

Hi devs, I'm implementing the LinkChecker UI and I want to be able to add a Tab in AllDocs. Right now I've coded it with a hardcoded #if but I really hate this. So here's my proposal: * Create the following modules: xwiki-platform-uiextension/ |_ xwiki-platform-uiextension-ui/ |_ xwiki-platform-uiextension-api/ where: * xwiki-platform-uiextension-ui/: contains XWiki.UIExtensionClass page * xwiki-platform-uiextension-api/: contains a ScriptService to get UIExtension data + contains an EventListener that refreshes the UI Extension Cache when an UIExtensionClass object is modified (this is for performance reasons) To start with I'm proposing to have the following fields for UIExtensionClass: * type: String, represents the type of the extension (for example for the AllDocs needs, I'll use a "IndexTab" type (or "AllDocsTab" type) * id: String, the technical name of the extension, which can be used for example as suffix for HTML class or ids. * name: String, the name of the extension, which can be used for displaying. For example for the AllDocs needs, it would be used as the name of the Tab * content: Textarea: the content of the extension. For example for the AllDocs needs, it would be used as the content to display when clicking on a tab I'd like to implement this ASAP and thus stop hardcoding UI Extensions from now on. Here's my +1 Thanks -Vincent PS: If you find a better than "uiextension" I'm all ears. A name without "extension" would be great to not confuse it with our Extensions (and with xwiki-platform-extension).

[xwiki-devs] monitoring the cache: how to get the eviction rate?

by Paul Libbrecht

Hello developers, I have been doing a nifty little cache monitor on www.curriki.org which is still running xwiki 1.5.4. It can show the entries and capacity of the two xwiki caches, pageExistCache and the document cache which sound pretty central. Not surprisingly, they're both full on our production server. name entries capacity pageExistCache 10000 10000 cache 3000 3000 The caches are using OSCache (through "OSCacheCache"). I've been trying to get a real statistical count but there I kind of failed thus far. I can use the StatisticListenerImpl which gives fairly high numbers: > StatisticListenerImpl: Hit = 9583563 / 1320251374, stale hit = 0 / 538, miss = 8541 / 17175236, flush = 27348, entries (added, removed, updates) = 25457741, 0, 7678101 these numbers are integers, and might actually be too small for the 2billions limit of an int, they are static (so count "all the OSCache instances"). What I would like to get is the "eviction rate" but I do not know how to compute it. That is, I wish to read the number of cache-entries which are thrown away because the cache is full and others come in. Once I can have it, I can start tuning (cache size, less greedy algorithms, ...) and measure the effect of such tuning. We have plenty of RAM space to accommodate the cache but we should use this well. The big annoyance with this process is that it can only run on our production server. So thus far I did not dare register a CacheListener in groovy fearing it would suddenly be slow. Has anyone used a different strategy or tool? I'm happy to post my little monitor script. thanks in advance. paul

[xwiki-devs] [VOTE] Naming rules for translation resource properties + deprecated properties

by Vincent Massol

Hi devs, I see that in ApplicationResources.properties we now have some wrongly named properties. For example for the scheduler I find properties of the type xe.scheduler.* but the scheduler is now in the platform. There are also resources named core.* Thus I'd like to propose a simple rule: <short top level projet name>.<short module name>.<propertyName> where: <short top level projet name> = top level projet name without the "xwiki-" prefix, for example: commons, rendering, platform, enterprise, manager, etc <short module name> = the name of the maven module without the <short top level project name> prefix, for example: oldcore, scheduler, activitystream, etc <propertyName> = the name of the property using camel case, ex: updateJobClassCommitComment For example the property core.importer.package.version would be renamed in platform.web.packageVersion The only issue is when we rename modules we need to rename the properties for that module but I don't see any way out of this if we want to have expressive property names. But at least it's an easy and mechanic change I also propose to introduce a different resource property file that will hold deprecated properties and that we can put in the xwiki-platform-legacy module. We could call it DeprecatedApplicationResources*.properties Of course in the future each module should be able to contribute both resource properties (but they would use the same naming scheme!). Even though this is not the topic of this mail this is how I'd implement this in the future: * Implement a TranslationPropertiesConfigurationSource that is initialized by reading all property files found in the classloader under META-INF/translations.properties and META-INF/translations-deprecated.properties. This component would listen to observation events so that when a new jar is installed by the extension manager it can check if it provides some translations and add them. * Have a Translation Manager component which is the main API to be used by other modules wishing to get translations. This manager would use the TranslationPropertiesConfigurationSource component. Here's my +1 Thanks -Vincent

[xwiki-devs] [VOTE] New {{display}} macro and changes to the {{include}} macro

by Vincent Massol

Hi devs, As you know in XE 3.0 we've changed the behavior for resolving local links/attachments when they're included using the {{include}} macro (they're now resolved against the included document instead of the including document). Now there might be some use cases (pretty rare IMO but they exist) where you'd want the links to be resolved against the including document. Here's a use case: you have a sheet document that references an image called image.png and you want that the including document provides it (like an Abstract in Java! ;)). So we've brainstormed with Thomas and here's our proposal: * Introduce a new {{display reference="…"/}} macro. This macro will *execute* the passed reference in its own context (it'll do what {{include context="new"…}} was doing before). It'll be located in the new display module. * Deprecate the "context" parameter of the {{include}} macro. The reason is that calling with context=new is not an include, it's a display. * Add a new "resolve" parameter for the {{include}} macro with possible values = "current" | "source", with a default value of "source". resolve=source means that the links/attachments are resolved against the source (ie the document being included). Using resolve=current means that you want the links/attachments resolved against the including document. Pros: * Clearly separate the 2 use cases: display and include * Make the include macro simple (a single "resolve" parameter) * Use the new display module as it should be and start the direction of having displayer macros for displaying all types of entities Note: In the future we'll also want to deprecate the "document" parameter of the include macro in favor of a more generic "reference" parameter, which will allow the macro to include other types of entities (such as an object property for ex). WDYT? Here's my +1 Thanks -Vincent

[xwiki-devs] [VOTE] Release XWiki Syntax 2.1 as official in Rendering 3.4

by Vincent Massol

Hi devs, I'd like to propose releasing XWiki Syntax 2.1 as official (it's currently experimental) for XWiki Rendering 3.4. Rationale ======== * It has useful expanded support for links and images compared to 2.0 * It's been "experimental" for a long time and people are already using it * It would be nice to release it in the 3.x cycle since it was started in that cycle * That would allow us to start XWiki Syntax 2.2 for the 4.x cycle (see outstanding items at http://tinyurl.com/6pdt5oa ) Migration aspects ============== * I don't think we need to mandate moving to 2.1 for users. They can keep using 2.0 if they want * We should make it the default wiki syntax starting in XE 3.4, leaving 2.0 available by default * I believe there's no conversion issue between 2.0 and 2.1 so it shouldn't be an issue for users wanting to switch. * We could provide a migration script on extensions.xwiki.org for users wanting to convert all their 2.0 pages into 2.1 pages Here's my +1 Thanks -Vincent

[xwiki-devs] [VOTE] Improve the database migration implementation on 3.4

by Denis Gervalle

Hi Devs, In order to change the way we compute document ID to reduce the likelihood of a collision, I need to improve and secure our current data migration system. I have started this works late during 3.2, but it since this is an important refactoring, and after discussion on IRC, it have been decide to wait for 3.4 to commit it, so we have a full cycle to have it carefully test. So I would like your approval now to commit this work. The advantages of these changes are: - Ensure that the hibernate store could not be access without having it migrated in the appropriate version for the running platform - Ensure that the hibernate store is left untouched if the migration have not been allowed - Easy addition of migrations, since migrator are now components - Schema and datamigration are done only once and together - One more step in the isolation of the store from XWiki - Secure enough to allow converting document IDs The impact on API and users are: - deprecate xwiki.store.hibernate.updateschema which is enable by default - xwiki.store.migration.databases=all by default (in place of xwiki) since this is the general UC - XWikiMigrationInterface and XWikiMigratorInterface are removed and new component roles DataMigrationManager and DataMigration should be used instead These improvements consist in: - Replace Migrators by DataMigration components - Replace the MigrationManager by a DataMigrationManager component - Put a "hibernate" hint on hibernate stores (in place of default) to allow the hibernate migrator to access a correctly typed store - inject and call the HibernateDataMigrationManager from the stores (and not from XWiki) - Convert data migration like action done during schema update (yes we have some sql updates during schema update) into a LegacyDataMigration producing data version 1 from data version 0 - Join together schema update and data migration on a unique place (schema update were currently done in several places in XWiki and the store) - XWIKI-1859: Do not start migrations on a clean installation of XWiki - XWIKI-2075: Move all databases upgrades and schema updates to XWiki's initialization instead of doing it lazily (partial fix, since it is still hard to have the store initialized has needed) - data migration is moved to the first access to a store (which is still during first request, but the matter is no more here) - XWIKI-2066: Migrator fails to upgrade sub wiki databases, now properly fixed (previous fix was a hack that do not) - no more excessive synchronization required for schema update, but there is still some mandatory document added lazily - clear reporting of access error when migration does not succeed For more, read http://markmail.org/thread/l3dzx7pj32n5qlqd Here is my +1 -- Denis Gervalle SOFTEC sa - CEO eGuilde sarl - CTO

[xwiki-devs] First alpha version of the GitHub App

by Ludovic Dubost

Hi devs, As we have moved to GitHub, I've started coding an equivalent of the SVNApp (http://extensions.xwiki.org/xwiki/bin/view/Extension/SVN+Application) for GitHub, which should ease up commiting pages from XWiki to GitHub, and because the GitHub SVN bridge is unfortunately not compatible with SVNKit. The bad news is that it's not a GitApp which seems very difficult to do as it relies on a local clone of the repository which is quite overkill when in an XWiki. The good news is that thanks to the GitHub API and a java wrapper from Eclipse, it seems fully possible to have the same functionnality as the SVNApp. I've made some good progress, as I've been able to check a repository against the Wiki AND I've been able to commit non existant files in an existing repository. The life proof is the commit of the GitHubApp itself which was done with GitHubApp: https://github.com/ldubost/application-githubapp/tree/master/src/main/resou… It's still a prototype as there is a lot of work left. For now every file is commited separately and I've not yet tested updating and other complexities, especially as the GitHub api is not that easy to work with (many times I had no errors but my updates were not showing up.

[xwiki-devs] [Proposal] Move Selenium2 platform PageObjects to platform

by Vincent Massol

Hi devs, I'd like to move Selenium2 PO classes for platform in xwiki-platform. The rationale is that: 1) it belongs to platform 2) it allows us to write functional tests in platform More precisely here's what I propose: * Move current unit test fwk currently in xwiki-platform-test to xwiki-platform-test-unit * Add a new xwiki-platform-test-functional module and move the PO objects + functional test classes in it FTM (in some future we'll move POs for a given module in that module but we're not quite there yet) I'm starting to work on this in few minutes so please let me know ASAP what you think. Thanks -Vincent
