[xwiki-devs] New cache component

by Thomas Mortagne

Hi devs, I'm working on a new cache component (http://jira.xwiki.org/jira/browse/XWIKI-2359) to replace the current cache service. For this I'm refactoring a little the API to improve extensibility. I will explain what I modified and I would like to have your point of views, suggestions and corrections on all this. First of all, how the current service works : You ask for cache service (which is more a factory than a service in fact) containing two major type of factory methods : - get a cache : create and return a new local or distributed (depends of the implementation) cache where you can put and retrieve object to cache with eventually a refresh period - get a local cache : force to get a cache store in the local computer All these methods return the same XWikiOSCache interface. I did not made lots of big modifications (as I want to be sure to correctly support all current service support), the main difference with the cache service (except the fact it now a factory component) is that I separate "normal" cache factory and "local" cache factory in two separate plexus roles. That way it could have different implementations configured in the xwiki.cfg like xwiki.cache.cachefactory.hint=memcache xwiki.cache.localcachefactory.hint=oscache And XWiki now contains getCacheFactory and getLocalCacheFactory methods in place of getCacheService. As a first example I moved the oscache cache service implementation as component : I attached a patch for it in http://jira.xwiki.org/jira/browse/XWIKI-2359 Thanks, -- Thomas Mortagne

Thus I'm not sure why you're testing for null? Am I missing something? In addition I think that if we really wanted to test for null then we should also have an else and display a warning if a notification cannot be sent. However I don't think it's normal that such a component cannot be lookup and we can safely assume it is found. The test should probably be modified to use AbstractXWikiComponentTestCase. WDYT?

[xwiki-devs] XE 1.4RC1 release and outstanding issues

by Vincent Massol

Hi devs, Since JV and I are at Javaone, Thomas Mortagne has kindly accepted to become the release manager for XE 1.4RC1. I've quickly reviewed the jira list of outstanding issues and I think the following should be fixed before the RC1 release: http://jira.xwiki.org/jira/browse/XWIKI-2274 http://jira.xwiki.org/jira/browse/XWIKI-1809 Also we need to verify that the Lucene plugin works fine and doesn't throw any error when we start XE and leave it running for a few minutes as it used to do (I think Sergiu fixed this). Anyone knows of any crucial outstanding issue for 1.4RC1? Note that RC1 means that it's a release candidate for being promoted to 1.4 final in a few days if its stable enough. The release was planned for last Friday so we need to set a new release date (tomorrow would be great). I'll let Thomas propose a date. Thanks -Vincent

[xwiki-devs] Deprecating all the APIs in favor of a Velocity uberspecting chain

by Sergiu Dumitriu

Hi devs, As suggested by Vincent, it would be cool not to have a distinct API for usage from velocity scripts, but pseudo-wrap the Java classes into a scriptable API using some uberspectors/introspectors. I like this idea a lot, as it is a bit hard to maintain two APIs (as the internal core is an API, just that it isn't directly scriptable), and with the new component architecture, the scriptable API would be completely unneeded. To remind, introspectors are used for finding the right methods to be called, given the target object, the method name, and the parameters; uberspectors must use introspector's results to construct velocity-specific objects for direct method calls ($something.methodCall()), getters (#set something = $object.getter), setters (#set $object.setter = something) and iterators (#foreach $iterator in something). During the last few days I wrote a chaining uberspector, that allows chaining several uberspectors, and a introspector chaining uberspector, that allows chaining several introspectors (not committed yet). The idea would be to have something like: [(introspector <- ... <- introspector)>- IntrospectorChainingUberspector <- Uberspector <- ... <- uberspector]>- ChainingUberspector Introspectors are chained in order to find or to filter out requested methods, then uberspectors use these methods to further enhance or restrict the method retrieving & calling process. So, a possible chain would be: BaseIntropector - finds methods using reflection. SecureIntrospector - filters out restricted objects/methods, like reflection, classloaders, threads/synchronization and the System class. ScriptableCheckIntrospector - blocks all direct calls to methods in the org.xwiki package that don't have an @Scriptable annotation. Note that it is possible to have calls to non-scriptable methods inside scriptable methods, as that is java code already, outside scripting. RightsCheckingIntrospector - uses the @Authorisation("accessright") annotations placed on our methods to perform rights checking. ProgrammingWrapIntrospector - not sure about this one, as I don't know how it could be implemented, but it would be nice to mimic all *WithProgrammingRights methods (like saveWithProgrammingRights), instead of literally having them in the java classes. ContextInjectionIntrospector - if no method was found, tries to find a method with an extra XWikiContext parameter. I must find a way to pass the request-specific XWikiContext (Vincent, any ideas?). This one is needed because all current API methods hide a non-scriptable method with almost the same signature, just an extra XWikiContext parameter at the end. This might not be needed if we completely get rid of the XWikiContext from the code before starting to use this chain. DeprecatedCheckIntrospector - logs deprecated method calls. IntrospectorChainingUberspector - calls the introspector chain and wraps the resulting methods into velocity objects (VelMethod, VelPropertyGet, VelPropertySet). ExceptionCatchingUberspector - catches all exceptions and puts them in the context (and logs them, too). ChainingUberspector - just allows having the uberspectors chain. I'm not sure if all those should be introspectors, or would be better as uberspectors instead. I didn't include the SecureUberspector in the chain, as besides the filtering done by the SecureIntrospector, it only checks if the returned iterator is restricted or not, and I don't think the iterators should ever be restricted. I don't know if the rights check should be left only to the introspector or not. Currently, this check is done mostly in the API classes only, suggesting that anything that happens in the java world is safe to execute, regardless of the access rights. Groovy doesn't need access rights check, as it requires programming rights from the start. XmlRpc should be a little more secure, but right now it doesn't use rights checks from the core classes anyway. So, any method we would like to be callable from Velocity should have an @Scriptable annotation. Rights checking could be performed entirely from an introspector. Any thoughts on this? -- Sergiu Dumitriu http://purl.org/net/sergiu/

[xwiki-devs] CalendarEvent - Failed to create diff

I attempted to edit the CalendarEvent Class by changing the Start Date and End Date format from: dd/MM/yyyy to: MM/dd/yyyy when I clicked Save & View I got this exception - I get the same exception if I attempt to rollback to a previous version?

[xwiki-devs] Adnotatio

Hi everyone, With Mikhail we created this generic GWT annotation tool that we may consider integrating into XWiki since it's bringing handy annotation features. The tool works fine only on static documents though for now. Annotation on evolving documents will require additional work.
