[xwiki-devs] Bug in XObjects, or am I using them incorrectly?
by ktc 14 Apr '17

14 Apr '17

I'm running into what appears to be a bug in how XObjects are removed and added, and wanted to ask if I am perhaps using them incorrectly. Basically I am performing the following sequence of steps: 1. Insert some XObjects to an XWikiDocument using document.newXObject(). Save the document and reload. 2. Delete one of the XObjects in the middle of the list of XObjects, using document.removeXObject(). Save the document and reload. 3. Add another XObject using document.newXObject(). Save. Here is that the document's xObjects data looks like after each step (simplified for demonstration purposes): AFTER STEP 1: index=0 object="<?xml...>...<number>0</number>...</xml>" index=1 object="<?xml...>...<number>1</number>...</xml>" index=2 object="<?xml...>...<number>2</number>...</xml>" AFTER STEP 2 (assume I delete the xObject with index=1): index=0 object="<?xml...>...<number>0</number>...</xml>" index=1 object=null index=2 object="<?xml...>...<number>2</number>...</xml>" AFTER STEP 3: index=0 object="<?xml...>...<number>0</number>...</xml>" index=1 object=null index=2 object="<?xml...>...<number>2</number>...</xml>" index=3 object="<?xml...>...<number>2</number>...</xml>" As you can see there are two related problems here: 1. A null object is being preserved in the list of XObjects, even after being rehydrated from Hibernate following a server restart. 2. The index=3 object has been given a 'number' of '2' -- but that number is already in use by index=2 object. Because of this, saving the document actually fails: I am receiving a NonUniqueObjectException as follows: org.hibernate.NonUniqueObjectException: a different object with the same identifier value was already associated with the session: [com.xpn.xwiki.objects.BaseObject#-1957000305211198111] Looking in the XWiki code it looks like this is essentially happening because the value of 'number' is computed as 'list size - 1'. So that 'null' that gets preserved in the list seems to be throwing off the logic. Am I using newXObject()/removeXObject() improperly? Please advise. Thanks! -- View this message in context: http://xwiki.475771.n2.nabble.com/Bug-in-XObjects-or-am-I-using-them-incorr… Sent from the XWiki- Dev mailing list archive at Nabble.com.

[xwiki-devs] [Brainstorming] Gradle exploration?
by Vincent Massol 12 Apr '17

12 Apr '17

BTW I think we’ll need to think about exploring gradle in not too long. Maven continues to stagnate while gradle is moving fast ahead. One important feature of gradle is performance (see also https://blog.gradle.org/introducing-gradle-build-cache and https://blog.gradle.org/incremental-compiler-avoidance) Apparently it beats maven easily and that coud make things much nicer for us. The worrying point for me is the ability to find existing gradle plugins to replace the maven ones that we use. What we could do is to commit the start of a gradle build in our SCM (starting with xwiki-commons) as a way to explore Gradle and see what’s missing compared to our current maven build. In other words, it would be a way to slowly start to learn Gradle. WDYT? Thanks -Vincent PS1: FTR I did my first gradle build at https://github.com/xwiki-contrib/docker-xwiki/blob/master/build.gradle PS2: I’m worried about the smaller reliance on conventions in gradle than in Maven (as you can see from https://github.com/xwiki-contrib/docker-xwiki/blob/master/build.gradle, it doesn’t use any fixed structure and we’ll need plenty of best practices, it really reminds me of Ant…).

[xwiki-devs] Maven 3.5.0 is out
by Vincent Massol 10 Apr '17

10 Apr '17

Release notes: http://maven.apache.org/docs/3.5.0/release-notes.html Interesting aspects for us: * The new project.directory special property adds support in every calculated URLs (project, SCM, site) for module directory name that does not match artifactId MNG-5878 * In previous Maven versions, there had been a larger problem related to memory usage in case of very large reactors (200-300 modules or more) which caused failures with out of memory exceptions or the need to increase the memory settings. This problem has been fixed with MNG-6030. Fixed bugs that could be interesting for us: * In previous Maven versions, there had been a larger problem related to memory usage in case of very large reactors (200-300 modules or more) which caused failures with out of memory exceptions or the need to increase the memory settings. This problem has been fixed with MNG-6030. Potential issues: * Replaced Eclipse Aether with Maven Resolver MNG-6110, MNG-6140. Thanks -Vincent

[xwiki-devs] [PROPOSAL] What name for the minimum XWiki flavor
by Thomas Mortagne 10 Apr '17

10 Apr '17

Hi devs, Since 8.0 we have in xwiki-platform a flavor simply called "XWiki Flavor" which contains more or less the strict minimum to have something you can call an XWiki instance (Administration, Extension Manager, a home page, etc.). Since we want to promote the new Knowledge Base flavor have a concurrent called "XWiki" is not really making it a favor so we should probably find another name for it. Here are some ideas: 1) "XWiki" Flavor, it's Ok after all 2) "Default" Flavor 3) "Base" Flavor 4) "Lite" Flavor 5) "Mini" Flavor 6) "Minimum" Flavor 7) "Pico" Flavor 8) <another word that means small> Flavor I don't think keeping "XWiki" is such a great idea. Default is even worst. I like "Lite" but might sound too much like "the very limited free version, you are going to have advertisement in a month" theses days. If I had to vote for only one it would be "Mini" but I'm fine with any of the following proposals. Thanks, -- Thomas Mortagne

[xwiki-devs] Should we provide a jetty/hsqldb package of Knowledge Base flavor ?
by Thomas Mortagne 10 Apr '17

10 Apr '17

Hi dev, The title say it all. The whole point of Knowledge Base flavor move is to stop maintaining a set of install packages and only provide the flavor. Now it could be a pain for testers to have to install the flavor every time so we might still release a jetty/hsqldb package but not list it on http://www.xwiki.org/xwiki/bin/view/Main/Download for example. WDYT ? I would prefer to avoid that but I can understand if others think it's required. Thanks, -- Thomas Mortagne

[xwiki-devs] Knowledge Base flavor
by Thomas Mortagne 10 Apr '17

10 Apr '17

Hi devs, We want since a while to get rid of XE and transform this custom distribution into an easier to maintain flavor you install on the default XWiki distribution. We finally allocated time in the roadmap to concentrate on it during 9.3-9.5 timeframe. The goal is to create a new flavor which would contain exactly the same things than XE for now. = The place My main question is: where do we put it ? There is two main possibilities IMO: 1) In platform under some xwiki-platform-flavors top level module which would contain the current base XWiki flavor (which is the strict minimum to have something that just work currently) and the new Knownledge Base flavor 2) In it's own repository 2.a) Synchronized with the platform repository like XE 2.b) With its own versioning I much prefer 1) which is a lot easier to maintain and release since this is going to be the main recommended flavor when you install XWiki. I really don't see the point of 2.a and 2.b does not worth the pain IMO. = The name The current "code name" in the core team is "Knowledge Base" but maybe some of you have better ideas. Here are some ideas: 1) Knowledge Base 2) Enterprise 3) Default My +1 goes to "Knowledge Base" which is more descriptive. Also I never really liked "XWiki Enterprise" naming since "Enterprise" suffix very often means that's the closed/paid version of an Open Source project which is not the case at all here. Thanks, -- Thomas Mortagne

[xwiki-devs] Why using artifactId as directory names was a good choice
by Vincent Massol 08 Apr '17

08 Apr '17

Hi devs, FTR founds this issue fixed in the just released Maven 3.5.0: https://issues.apache.org/jira/browse/MNG-5878 This shows that not using artifactId as project names was leading to some issues till Maven 3.5.0. Mentioning this since there’s been several discussions over the years to remove prefixes and I remember that some devs have done that in some xwiki-contrib repos so maybe there’s an issue there. Thanks -Vincent

[xwiki-devs] Modal Popup Link with API REST
by SebastianM 07 Apr '17

07 Apr '17

Hello everyone, I'm new one on Xwiki and i need your assistance to customise a form. I created a new form page on my xwiki. This page containt a html form that makes a http GET request on a servlet and this one connects to a SQL DB and performs some processing before returning a CSV. This works well but the user has nothing to tell him that his query is being processed. I would like to display a popup to make the user wait until the download window appears and close automatically or display an error message (Your request is too large, Your query does not contain a result, ...) if serveur return an error. Is it possible to do this on xwiki? Someone has already done it and could show me how to do it? Here is my xwiki code right now : {{velocity}} #set ($discard = $xwiki.ssfx.use('uicomponents/widgets/datepicker/calendarDateSelect.css', true)) #set ($discard = $xwiki.jsfx.use('uicomponents/widgets/datepicker/calendarDateSelect.js', true)) ## Used to parse and serialize the selected date using the date format specified in the XClass. #set ($discard = $xwiki.jsfx.use('uicomponents/widgets/datepicker/simpleDateFormat.js', true)) ## A wrapper over the CalendarDateSelect widget that uses the SimpleDateFormat to parse/serialize the dates. #set ($discard = $xwiki.ssfx.use('uicomponents/widgets/datepicker/dateTimePicker.css', true)) #set ($discard = $xwiki.jsfx.use('uicomponents/widgets/datepicker/dateTimePicker.js')) #set($firstName = $xwiki.getDocument($context.user).getObject('XWiki.XWikiUsers').getProperty('first_name').getValue()) #set($lastName = $xwiki.getDocument($context.user).getObject('XWiki.XWikiUsers').getProperty('last_name').getValue()) {{html}} <div> <form role="form" action="http://10.132.121.142:8080/servlet1/data" method="get" id="requete"> <div class="form-group"> <label class="col-md-2 control-label">Libelle</label> <div class="col-md-2"> <input type="text" name="libelle" class="form-control" placeholder="Libelle"/> </div> </div> <div class="form-group"> <label class="col-md-2 control-label">Instant de début</label> <div class="col-md-2"> <input type="text" pattern="^(?:(?:([01]?\d|2[0-3]):)?([0-5]?\d):)?([0-5]?\d)$" name="startinstant" class="form-control" placeholder="00:00:00"/> </div> </div> <div class="form-group"> <label class="col-md-2 control-label">Date de début</label> <div class="col-md-2"> <div> #set ($format = 'dd/MM/yyyy') #set ($value = $datetool.date) <input name="startdate" type="text" value="$!escapetool.xml($datetool.format($format, $value))"class="datetime t$!value.time" title="$!escapetool.xml($format)" /> </div> </div> </div> <div class="form-group"> <label class="col-md-2 control-label">Region</label> <div class="col-md-2"> <select name ="region" class="form-control select"> <option value="ALL">ALL</option> <option value="TEST1">TEST1</option> <option value="TEST2">TEST2</option> </select> </div> </div> <div class="form-group"> <label class="col-md-2 control-label">Instant de fin</label> <div class="col-md-2"> <input type="text" pattern="^(?:(?:([01]?\d|2[0-3]):)?([0-5]?\d):)?([0-5]?\d)$" name="endinstant" class="form-control" placeholder="00:00:00"/> </div> </div> <div class="form-group"> <label class="col-md-2 control-label">Date de fin</label> <div class="col-md-2"> <div> #set ($format = 'dd/MM/yyyy') #set ($value = $datetool.date) <input name="enddate" type="text" value="$!escapetool.xml($datetool.format($format, $value))"class="datetime t$!value.time pull-right" title="$!escapetool.xml($format)" /> </div> </div> </div> <div class="form-group col-md-2"> <div> <input type = "hidden" name = "firstname" value = $firstName /> <input type = "hidden" name = "lastname" value = $lastName /> <button type="submit" class="btn btn-primary dropdown-toggle">//TELECHARGER</button> </div> </div> </form> </div> {{/html}} {{/velocity}} -- View this message in context: http://xwiki.475771.n2.nabble.com/Modal-Popup-Link-with-API-REST-tp7603415.… Sent from the XWiki- Dev mailing list archive at Nabble.com.

[xwiki-devs] XWiki on sonarqube.com
by Vincent Massol 07 Apr '17

07 Apr '17

Hi devs, FYI I’ve created an organization for xwiki on https://sonarqube.com at: https://sonarqube.com/organizations/xwiki/projects This using the default Quality Gate from sonarQube and right now it’s not possible to configure it. However they’re tuning it a lot and they told me that within 2 months there should be a lot less false negatives (there are plenty right now). SonarSource will ping me when it’s done (they’ll use XWiki to tune it). The following step is to be able to define Quality Gates per project on sonarqube.com. They’ll think about it. My idea ATM is: * Once the quality level is good enough, move to sonarqube.com instead of maintaining our own sonar.xwiki.org (ie have sonar.xwiki.org redirect to it). Right now we’re lagging behind a lot and using one of the worst version of sonarqube (but upgrading is difficult and depends on XWiki SAS infra and they have other priorities). * In the future, define some XWiki-specific Quality Gates to fail our CI Sonar jobs. WDYT? Thanks -Vincent

[xwiki-devs] [GSoC] [coding sample Jira issues]
by Krzysiek Płachno 03 Apr '17

03 Apr '17

Hello, I want to do some JIRA task as a part of my application for GSoC. I encountered some doubts. 1. I asked questions in comments in 2 issues. Is it the proper way of discussing them or should I ask about them on mailing list? Links to those issues: https://jira.xwiki.org/browse/XWIKI-13496?filter=10534 https://jira.xwiki.org/browse/XWIKI-12704?filter=10534 2. When I do fixes on my local repository and I want to create Pull Request I need to upload them to one of remote branches - typically branch created specially for my fix, right? It seems that option of creation branches on github is disabled for externals like me. How can I upload my fixes and create PR, then? 3. I've searched dev guides and also names of created branches on github. What's the convention for proper naming of bugfix or feature branches? Examples that I found are following: "feature-XWIKI-12544", "feature-alfresco-link" or simply id of ticket: "XWIKI-7553" I know that I sit down to coding a bit late, but I hope I'll manage do upload at least one Pull Request before deadline. Best, Krzysiek P.S. I haven't encountered any Java project so far in which the code convention was to put opening curl bracket '{' in new line :)

[xwiki-devs] [GSoC] More extension repositories
by Krzysiek Płachno 02 Apr '17

02 Apr '17

Hi, I'm about to prepare a plan and timeline with milestones for the task "More extension repositories ". The page with design details ( http://design.xwiki.org/xwiki/bin/view/Design/ExtensionManagerRepositories) gives 10 examples of repositories to set an integration with, whilst the description of task on XWiki GSoC information sub page refers only to 3: Nexus , Bintray , Pypi ( http://dev.xwiki.org/xwiki/bin/view/GoogleSummerOfCode/Moreextensionreposit…) . So the task for GSoC work includes integration with all those 10, or just those 3? I need to know it to plan well the milestones. Best, Krzysztof

[xwiki-devs] Glossary Application
by Sarthak Gupta 01 Apr '17

01 Apr '17

Hi, On the IRC, I asked about the meaning of the term "Rendering transformation". I went through the Rendering Framework doc and found that 'Rendering' is just a way to convert the DOM (Data Object Model: it connects different programming languages) into a valid output which is shown to the user. Now in the project "Glossary Application" , the idea is to present a list of definitions in the glossary app. I wanted to inquire if the definitions of the 'technical terms'(words which a user while going through the x-wiki page will find difficult to understand) of the x-wiki page is to be listed in the glossary app? And when user clicks on that word then a new page opens listing the definition of that term, feature etc? Thanks :)
