[xwiki-devs] [VOTE] Use discourse for the "dev" mailing list

by Guillaume Delhumeau

Hi devs, I think we are now satisfied with our experimentation with the "users" mailing list on discourse. I propose you to move the "dev" ML too. My main point is that it allows advanced formatting (which is good when you have complex proposals), meanwhile the formatting is lost with our archiving tool like markmail (it's plain text). Here is my +1. Thanks, -- Guillaume Delhumeau (guillaume.delhumeau(a)xwiki.com) Research & Development Engineer at XWiki SAS Committer on the XWiki.org project

[xwiki-devs] [proposal] Process to handle Pull Requests

by Ludovic Dubost

Hi devs, I don't think there is currently a process that is in place to handle pull requests and I have the feeling that the way there are handled today is a bit random. There are usually comments sent out on each pull request but sometimes it seems that some pull requests are going in sleep mode and it's not clear who is in charge. I would like to suggest that a process is put in place where it's clear who is responsible for a pull request and a status is given to the contributors that propose that pull request. Something like: Assigned developer: XXXX Status: New -> new pull request, not yet assigned Assigned -> assigned to a developer, he is in charge of reviewing the pull request and ask for modifications or accept it. The developer can auto assign it to himself. If nobody does, we need to decide how they will be taken into account. ModificationsRequired -> for now rejected with comments. Contributor needs to apply comments and then change back to Assigned for further evaluation VoteRequired -> there are no more comments, but a vote is required as the changes to XWiki core are important WaitingFinalAuthorization -> optional step for complex patches where a additional authorization would be required (need to define who would be the persons that give the authorization) WaitingApplication -> there are no more comments and no changes or vote required. The pull request can be applied and is waiting for a developer to apply it Abandoned -> contributors is abandoning the pull request (cannot do the changes, no more time, etc..) Rejected -> pull request is rejected (quality not enough, etc..) Applied -> pull request is applied What do you think ?

[xwiki-devs] [VOTE] Drop support for IE11

by Ecaterina Moraru (Valica)

IE is the last browser we are supporting at a particular version, see http://dev.xwiki.org/xwiki/bin/view/Community/BrowserSupportStrategy . For all the other browsers, we are supporting just the latest release. We are supporting the latest version of Microsoft Edge since XWiki 9.9, starting from 24/Oct/17. Microsoft Edge replaced Internet Explorer as the default web browser since the release of Windows 10 (launched Jul 2015). Internet Explorer 11 is maintained on Windows 10 for compatibility purposes, but is deprecated in favor of Edge and is no longer actively developed. We discussed dropping IE11 in the past Oct 6, 2017 (see https://xwiki.markmail.org/thread/qsrkka6zfrmyxv3d), but the vote failed. Some updated statistics: -------------------------------------------------- XWiki.org's 1 year traffic (between Sep 30, 2016 - Sep 30, 2017) compared to Oct 1, 2017 - May 31, 2018: - Internet Explorer dropped from (5.84%) to (4.65%) -- from this percentage, IE 11 usage has increased from (88.43%) to (88.76%) - Edge increased from (1.56%) to (1.84%). In terms of Worldwide market share for Desktops, for the past 12 months (according to http://gs.statcounter.com/browser-market-share/desktop/ ), we have Sep, 2016 - Sep, 2017 compared to May 2017 - May 2018: - Internet Explorer dropped from 8.21% to 6.97% - Edge dropped from 4.3% to 4.15% In May 2018, Global Market Share Worldwide for All Platforms contains: - Chrome 58.09% - Safari 13.78% - UC Browser 8.16% - Firefox 5.27% - Opera 3.68% - Internet Explorer combined is at 3.08% (with IE 11 having 2.65%. IE11 in August 2017 had 3.04%) - Edge combined having 1.91% (Edge combined in August 2017 had 1.8%) - etc. -------------------------------------------------- In terms of statistics, IE11 is more used than Microsoft Edge. The only argument of dropping IE11 is that it's a browser that is deprecated for about 3 years, and it's limiting the usage of newer specifications (like CSS Flex, Grid, etc.) I'm curios about how this period of supporting both IE11 and Edge went, and if you have other examples of things you wanted to use and are not supported by IE11. Thanks, Caty

[xwiki-devs] [Proposal] Get rid of sonar.xwiki.org?

by Vincent Massol

Hi devs, Context: * I lost the config on ci.xwiki.org to push maven results to sonar.xwiki.org. I can find them back for sure but will take me a bit of time. * We don’t use sonar.xwiki.org that much * We now have https://sonarcloud.io/organizations/xwiki/projects to which we can push results from our builds * https://sonarcloud.io/organizations/xwiki/projects is always up to date in term of sonar version and we don’t need to maintain it So my proposal is to decommission sonar.xwiki.org and to configure https://sonarcloud.io/organizations/xwiki/projects the way we want (I already did that a bit but we can tune it more) and modify our maven build to push to it. WDYT? Thanks -Vincent

[xwiki-devs] [Discussion] Coding practice for location of internal package name

by Vincent Massol

Hi devs, On Matrix/IRC, I’ve posted the following: " * Guillaume Delhumeau: BTW your naming is strange for the internal package * for ex: package org.xwiki.notifications.preferences.internal.email; * normally we put internal just after the main package part * ie. * org.xwiki.notifications.internal.* * and org.xwiki.notifications.* for public classes * see http://dev.xwiki.org/xwiki/bin/view/Community/CodeStyle/JavaCodeStyle/#HPac… * General rule is org.xwiki.(module name).internal. * I see thomas has done the same “error" for org.xwiki.job.handler.internal and org.xwiki.job.handler.internal.question . So maybe there's something to discuss/change * I guess we have a mix of both now so we should discuss it and adjust our rules if need be “ So I think we don’t have all the same rules/understanding of the definition at http://dev.xwiki.org/xwiki/bin/view/Community/CodeStyle/JavaCodeStyle/#HPac… I’d like to discuss with you to see what you prefer and adjust our rules so that it matches what we do in practice. Any take in this? Thanks -Vincent

[xwiki-devs] [Brainstorming] Finish refactoring for xwiki configuration directories

by Vincent Massol

Hi devs, Context ====== Clemens fixed a bug at https://jira.xwiki.org/browse/XWIKI-15163 and while doing so inroduced a new system property to override the location of the xwiki.properties file. I commented at https://jira.xwiki.org/browse/XWIKI-15163?focusedCommentId=98075&page=com.a… Even though it’s not necessary to introduce a new system property just for the need of this test (it’s easy to refactor the code to not need this IMO), it raises the question of what we want to do to make the configuration simpler in XWiki (simpler config, simpler upgrades, etc). History ====== We discussed this a few times in the past: * March 2010: http://markmail.org/message/6cvm5hocvtbqtgp6 * June 2012: https://markmail.org/message/3aq2bjrb6a2ip2ri Note that the June 2012 proposal was agreed. Globally this is what we implemented since the June 2012 proposal: * XCOMMONS-187: The Permanent Data directory resolver should support System Property "xwiki.data.dir". More specifically the code is here: https://github.com/xwiki/xwiki-commons/blob/55569d3466dc0ea36f6964474973f7a… * XWIKI-13867: Search xwiki.cfg in /etc/xwiki/ first. Code is here: https://github.com/xwiki/xwiki-platform/blob/973d4e9c6ad02dbb31d94fe96df9c1… * XWIKI-13868: Search xwiki.properties in /etc/xwiki/ first. Code is here: https://github.com/xwiki/xwiki-platform/blob/93f02215783ac0f4030fe3062cac4d… I’d like to note that I don’t remember discussions/proposals for XWIKI-13867/XWIKI-13868 and I commented on http://jira.xwiki.org/browse/XWIKI-13867 and didn’t get any response from my various comments. Current behavior ============= So right now the behavior is the following on config files (I’m excluding the recent change of Clements, see below in actions): * If xwiki.cfg exists under the. "java:comp/env” JNDI key, then it’s used * If not found, then search for it in /etc/xwiki/xwiki.cfg * If not found, then default to WEB-INF/xwiki.cfg * If /etc/xwiki.xwiki.properties exist then it’s used * if not found, search in WEB-INF/xwiki.properties (as a ServletContext resource) * If not found, then default to an empty configuration Discussion/Proposal ================ * I think we should ask Clemens to rollback the introduction of the xwiki.properties.default.dir system property and to just make the test work without introducing any system property. I can help Clemens do that. * I propose that instead we continue implementing the June 2012 proposal defined at https://markmail.org/message/3aq2bjrb6a2ip2ri and introduce the xwiki.config.dir system property. * Right now I don’t like the solution introduced by /etc/xwiki/* because they don’t allow supporting several instances of XWiki on the same machine. However, the introduction of xwiki.config.dir system property would fix it. * We could also introduce the user home dir location as a location where xwiki config files would be looked for. * We also need to generalize the config files to hibernate.cfg.xml and clustering config files (jgroup files), and logback. See https://www.xwiki.org/xwiki/bin/view/Documentation/AdminGuide/Backup#HConfi… WDYT? Thanks -Vincent PS: Sorry for the long mail, I had to do a lot of archeology to research this… Took me a while ;)

[xwiki-devs] State of Velocity 2.0 upgrade

by Thomas Mortagne

Hi devs, Some of you may know that I started working on upgrading our scripting engine to Velocity 2.0. The corresponding Jira issue is https://jira.xwiki.org/browse/XCOMMONS-1296. Those of you who want to take a look at breakages with standard Velocity 2.0 upgrade (if you directly use Velocity API) can take a look at http://velocity.apache.org/engine/2.0/upgrading.html. The following details are about XWiki Velocity "engine": = The code You can see the current state of the upgrade on the following branches: * https://github.com/xwiki/xwiki-commons/tree/feature-velocity2 * https://github.com/xwiki/xwiki-rendering/tree/feature-velocity2 * https://github.com/xwiki/xwiki-platform/tree/feature-velocity2 = Bad news == Definitive (probably) breakages * it was not easy in Velocity 1.7 but it's now impossible in Velocity 2.0 to use the hack we currently use to make macro "return" something. I mitigated this a bit by working on a #setVariable directive (the name of the helper we currently have in macros.vm) but it's not yet working in all situations and any code that was not going trough #setVariable will be broken anyway * the hypen ( - ) cannot be used in variable names anymore Those changes make impossible to upgrade to Velocity 2.0 in 10.x branch IMO, to big to be done in the middle of a cycle. == Temporary (hopefully) breakages * impossible to have $ or # at the end of a " based string literal (we have that a lot in various regex for example). This looks like an unplanned regression (since it's not documented) so I'm waiting for some kind reaction in the issues I reported (https://issues.apache.org/jira/browse/VELOCITY-897 and https://issues.apache.org/jira/browse/VELOCITY-896) == Not too impacting (hopefully) breakages The Velocity API changed quite a lot, fortunately not in classes we expose publicly (basically all we expose is VelocityContext). Also reminder: directly manipulating even XWiki Velocity API is considered legacy things (better use templates or wiki content and ScriptContext). = Good news == Macros handling The way to manage namespaces and macros has been completely changed (it does mean that lots of API has been broken in the process but we don't expose this API) and the good news is the new design will allow us to (finally) do proper caching of velocity scripts. I also removed a few hacks we had to do to not end up with endless memory leaks and milti-thread issues caused by the old namespace handling system. == Less stuff on our side I was able to move the following to legacy: * an equivalent of our chainable uberspector system has been implemented in Velocity standard * a DeprecatedCheckUberspector has been implemented in Velocity standard == Retro compatibility I was able to add * XWiki will keep supporting $velocityCount and $velocityHasNext (with a warning). It imply using XWikiVelocityContext instead of VelocityContext if you create it directly (which is a very bad idea) but you don't need to worry about that if you get your context from VelocityManager * a new #setVariable directive help supporting a few use case of macro "return" but unfortunately not all yet (Velocity AST is not super obvious to navigate...) == Performances Other than the caching on our side I already mentioned (huge boost planned when implemented) there is some memory and performance improvements claims in Velocity 2.0 release note (but I did not had time to do any testing myself yet). = TODO a) waiting for answer about the regressions I reported b) try find a way to make #setVariable directive works in a macro which is itself called in another macro (but it may not be possible) c) send a mail to discuss when to merge the Velocity 2 branch when at least a) is resolved Thanks, -- Thomas Mortagne

[xwiki-devs] [Proposal] XS 10.7 roadmap on BFD+Test

by Vincent Massol

Hi devs, We’re having a tough time maintaining the quality of XWiki Standard these days (not enough people). We used to be able to contain bugs and have as many bugs closed than created over 1600 days. We’ve now slipped back to 330+ bugs that have been opened vs created over 1600 days. +116 over 500 days. +96 over 365 days. And +49 over 120 days. BFD days have little impact with that many bugs (since there are about 1-2 devs participating to XS’s BFDs). In addition I’ve measure our Test Coverage since end of 2017 and we’ve lost coverage compared to before which is really bad (see my other emails). In short this means that we’re hurrying to finish work from the roadmaps without taking enough time to write the proper tests. This will have an important impact in the future if we don’t react. Thus I’d like to propose that we spend the XS 10.7 roadmap (1 month in August) on bug fixing and writing more tests. It’ll probably not be enough but it’ll help a lot. Let me know if someone has a counter-proposal or an issue with this proposal. Thanks -Vincent

[xwiki-devs] [Contrib] New repo and JIRA for an OpenStreetMap macro

by Stéphane Laurière

Hi devs, We have a MapMacro already [1], for displaying Google Maps. I'd like to create a distinct one for creating maps based on OpenStreetMap. Another option would be to enhance the existing MapMacro for supporting the display of OSM maps in addition, but this would make the code more complex, and in general an administrator willing to use maps in his wiki is likely to opt for one map type, probably not both, what do you think? If you agree, the proposed repo name and JIRA would be: - Repo: macro-openstreetmap - JIRA project: OSM [1] https://extensions.xwiki.org/xwiki/bin/view/Extension/Map%20Macro Thank you, Stéphane -- Stéphane Laurière XWiki www.xwiki.com @slauriere

[xwiki-devs] First batch of the new experimental Page oriented APIs

by Thomas Mortagne

Hi xwikiers, Some of us discussed that for a while and created/improved http://design.xwiki.org/xwiki/bin/view/Proposal/DeprecatingSpaceAndSpaceRef… and I finally started working on it. So here is what I pushed on master already: = PAGE EntityType and Page*Reference classes First thing first we now have a few new type in EntityType and the corresponding typed Page*Reference helpers. One for each of the element you can have in a page: * PAGE * PAGE_ATTACHMENT * PAGE_OBJECT * PAGE_OBJECT_PROPERTY * PAGE_CLASS_PROPERTY = Corresponding resolvers/serializer/providers Each of the already existing DOCUMENT oriented resolvers and serializers have their PAGE oriented implementation. = Conversion from DOCUMENT to PAGE world The entity resolvers automatically convert from/to DOCUMENT from/to PAGE world references. Do yes using a resolver is the official way to do that conversion. = Model script service The $services.model API also got his own new helpers to manipulate pages = New syntax Last but not least: pages reference have a very different syntax. To summarize it's a filesystem path syntax with support for parameters. Here is are a few examples: wiki:page1/page2;param1=value1;param2=value2;en_US wiki:page1/page2/attachment ../siblingpage * separator: "/" between all elements except WIKI which is still ":" * escaping: still "\" * current, parent support: like in a filesystem you can refer to the current page or parent page/wiki using "." and ".." * parameters: we now have syntax to express the parameters of an EntityReference. Each parameter is separated by a ";" at the end of the entity name * default parameter: the syntax have the concept of default parameter which mean a parameter for which you don't need to indicate the name. For example PAGE reference default parameter is "locale" = TODO The next elements on the short term TODO list are: * support for page references in XWiki#getDocument (which essentially means add a fallback) * support for page references in various macros (generally means adding a "page" parameter as alternative to the existing "reference" or "document" parameter) Thanks, -- Thomas Mortagne
