[xwiki-devs] Some problem while writing tests.
by Sarthak Gupta 30 Oct '17

30 Oct '17

Hello, I have a component implementation GlossaryTransformation.java <https://github.com/xwiki-contrib/application-glossary/blob/master/applicati…>. So it has two methods List<String> getGlossaryEntries() and transform(Block block, TransformationContext context) in it. So, I have a test file https://pastebin.com/NixuBMjD for this component. Here I am trying to mock the behavior of getGlossaryEntries method by putting strings ("glossaryEntry1" and "glossaryEntry2"). And then implementing "when(this.glossaryTransformation.getGlossaryEntries()).thenReturn(mockArrayList);" but this line somehow shows NullPointerException. On searching on StackOverflow, I found that this is happening because the object of "glossaryTransfromation" is not created, but only a reference is created. So, I tried to put glosaaryTransformation = "mock(GlossaryTransformation.class)" in the code. Yes, the above error was resolved, but the line "Parser parser = this.mocker.getInstance(Parser.class, "xwiki/2.1");" gave an error " ComponentLookupException: Can't find descriptor for the component [role = [interface org.xwiki.rendering.parser.Parser] hint = [xwiki/2.1]]" . Is there a better way to achieve this? Or I think a better approach can be to put the Query method (getGlossaryEntries) of GlossarryTranformation.java in a separate class and then create a mock object for that class and then run the test? Thanks -Sarthak Gupta

[xwiki-devs] [Proposal] Replace OpenJS Keyboard JS with Keypress JS for handling keyboard shoirtcuts
by Vincent Massol 29 Oct '17

29 Oct '17

Hi devs, We’re currently using http://www.openjs.com/scripts/events/keyboard_shortcuts/ but it has some limitations. Clement and I tried to find some unused combinations of keys that works on Mac and Unix and we couldn’t find any that worked with it. It also doesn’t support having combinations with several letters for example. For example we could imagine having H+H+H for turning on/off hidden documents (as a developer key sequence since it’s not a user use case). I’d like to propose using https://dmauro.github.io/Keypress/ which is under the Apache 2 license and that seems to work well on Mac and Unix and it’s very powerful. See sequence combos for example. The API look simple and nice and I don’t think it would be hard to continue support our data structure inside the “shortcuts” variable to make it work with it. WDYT? Thanks -Vincent

Hi everyone, We just received a mail from Google confirming us that we have been selected ! So we now (actually as soon as the website will be in sync with the mails :)) have 1 month to create tons of tasks for the students. And if you did not added yourself to http://dev.xwiki.org/xwiki/bin/view/GoogleCodeIn/#HMentors it's not tool later and we would be happy to welcome more mentors :) Have fun ! -- Thomas Mortagne

Here it is the cache object. So, an alternative here can be to use the "query module" everytime for knowing which entries are present in the Glossary Space. And that would slow down the Xwiki to a large extent I guess because for each word a query will be executed. Would using the "Query" be fine or there can be any other better approach? Some ideas: Version 1.0: * When the transformation executes (i.e. when a page is rendered), you do a query to get the glossary entries. Version 1.1: * You make your transformation implement Initializable and in initialize() you go a query to get all existing Glossary entries that you save in a cache component that you write * The cache component internally uses a Cache<> object for storing the Glossary entries * You also implement a component implementing EventListener that gets the cache component injected so that you can update the cache when glossary xobjects are created/modified/deleted. If you feel comfortable you can implement directly version 1.1 but my recommendation would be get a working v1.0 version ASAP and then iterate to improve it. Hope it helps, Thanks -Vincent PS: Please keep the discussion on the list so that anyone can help you and see the answers and chime in or just learn from it! :) > Thanks > > Sarthak Gupta > > > > > > I have a question in my mind. > > > > The "cache" and the "event Listener" are to be implemented as two separate > > components. right? > > Correct. > > > What I think is, that the EventListener component should be filled with > > appropriate methods just like this > > <https://github.com/xwiki/xwiki-platform/blob/master/xwiki-platform-core/xwi…> > > and > > then in these methods, the cache should be updated. > > > > Is this implementation right? > > Correct. > > > And after this, the rendering part will come…. > > Awesome. > > Thanks.

[xwiki-devs] XWiki Security Cache global read/write lock scalability
by ktc 26 Oct '17

26 Oct '17

We ran into an issue recently where users were not able to access the Wiki due to the XWiki security cache holding up access to read requests as we were experiencing heap exhaustion. A thread dump of a host showed that there were 211 security cache read locks and 2 security cache write locks during the event. Read locks are supposedly parallelizable, so we suspect that it was the write locks that blocked the read requests. Looking into the write locks, we found *DefaultSecurityCacheRulesInvalidatorListener* shares a read-write lock (*SecurityCacheRulesInvalidator*) with the security cache loader (*DefaultSecurityCacheLoader*). It appears that these write requests to the security cache were potentially creating a deadlock, blocking any further read requests. Our investigation of this event resulted in the following questions that we are hoping to get answered by reaching out here: 1. What exactly happens in the event of a write failure to the Security Cache? Are we correct in understanding that the write request will continue to hold a lock on the cache, preventing all read requests from proceeding? 2. If so, are there any mitigations around the global read-write lock on the security cache? Or, perhaps, is the best action is to simply move toward a more scalable caching mechanism (i.e. a centralized cache such as Elastic Cache)? 3. It looks as if all threads doing a read/write request to the SecurityCache were all parked waiting for the same thread (3081f946); however, the thread is not showing up in the thread dump so we are not sure what it is stuck on. Does the XWiki team have any suspicions as to what could be hold up the requests to the SecurityCache? Thank you! --- For more information on the event: >From our investigation, we concluded that the outage happened because: 1. Remote events triggered a security cache update and requested a couple of write locks 2. The writes could not execute (perhaps due to the heap exhaustion, although root cause of write failure is unknown) 3. ReentrantReadWriteLock lock followed a fair policy, which releases locks in time order, so read requests were forced to wait for any previous write requests to finish. Because the write requests couldn't finish, the remaining 211 threads were blocked. * Possible remote events that trigger security cache update: changes to an XWiki group such as leaving the admin group, user first time visiting XWiki, etc.. ---- *LDAP Connection Lock example:* Thread t@225108 java.lang.Thread.State: TIMED_WAITING at java.lang.Object.wait(Native Method) - waiting on <7249fc39>

[xwiki-devs] [application-glossary]
by Sarthak Gupta 22 Oct '17

22 Oct '17

Hi, I am trying to build the application-glossary-api module but it is failing and is showing in the stack trace "Caused by: java.lang.ClassNotFoundException: org.xwiki.tool.enforcer.ExternalExtensionCheck". I googled it and found that may be the class is missing from the classpath, so I added : <groupId>org.xwiki.commons</groupId> > <artifactId>xwiki-commons-tool-enforcer-dependencies</artifactId> > <version>${commons.version}</version> as a dependency in the api pom.xml, but that doesn't seem to work. Stack Trace: https://pastebin.com/3rJu1MJv Thanks Sarthak Gupta

[xwiki-devs] [Call to Action] Looking for Google Code-In mentors
by Vincent Massol 22 Oct '17

22 Oct '17

Hi everyone, Thomas and I would like to try the Google Code-In (GCI) programme this year (GCI is for high school students). We’ve been participating to lots of discussions about it at the GSOC summit 2017 and it seems like it could bring some interesting things for the XWiki project. Our goal: * Participate to GCI * Kill 2 birds with one stone and create an onboarding programme for anyone wanting to contribute to XWiki without any knowledge Here’s what we’ve done so far: * We’ve started registering XWiki as an org on https://codein.withgoogle.com/dashboard/ * We’ve also started creating the GCI pages on xwiki.org at http://dev.xwiki.org/xwiki/bin/view/GoogleCodeIn/ * We’ve started creating GCI issues in XWiki (reusing existing JIRAs + creating new ones). The idea is to map our Paper Cuts ideas we had (http://dev.xwiki.org/xwiki/bin/view/Main/PaperCut) with GCI. ** In practice a GCI issue is a “Trivial” issue, labelled with “GCI”. Next immediate steps: * Finish the application process before the 24th of October. We’ll know on the 26th of October if we’re selected or not. * Find at least 10 mentors for the programme. We’re currently 2. A mentor doesn't need to be an expert in XWiki at all since the GCI tasks need to be super simple with very clear success criteria. So we need the maximum of mentors. We need to be prepared to handle 10-50 students at all time participating to XWiki GCI tasks! ** Example of people who could be mentors: committers, contributors, QA/testers, XWiki users, ex-GSOC students * Before the 28th of November have at least 200 tasks defined. IMPORTANT: The mentors are not assigned to any student and we work as a pool of mentors (it’s not like GSOC!). A mentor can handle validating tasks and answering questions from students at the intensity that they want (could be as low as doing that for a few tasks only). Please let us know quickly if you’re willing to be a mentor for GCI! Thanks -Vincent
