[xwiki-devs] [XWiki Day] BFD#144
by Vincent Massol 10 Jun '17

10 Jun '17

Hello devs, Today is BFD#144: http://dev.xwiki.org/xwiki/bin/view/Community/XWikiDays#HBugfixingdays Our current status is: * -49 bugs over 120 days (2 months), i.e. we need to close 49 bugs to have created bugs # = closed bugs # * -5 bugs over 365 days (1 year). * -51 bugs over 500 days (between 1 and 2 years) * +13 bugs over 1600 days (4.3 years) * -633 bugs since the beginning of XWiki See https://jira.xwiki.org/secure/Dashboard.jspa?selectPageId=10352 It would be great if today we could at least fix 5 bugs to be even on the 365 day period. But more generally we’ve accumulating some lag recently with -49 bugs over 120 days. So we need to start catching up a bit. Here's the BFD#143 dashboard to follow the progress during the day: https://jira.xwiki.org/secure/Dashboard.jspa?selectPageId=13896 Happy BugFixing Day, -Vincent

[xwiki-devs] [PROPOSAL] Rename downloadable packages while releasing them
by Thomas Mortagne 09 Jun '17

09 Jun '17

Hi xwikiers, Eduard hard the idea of dynamically rename the files names of the packages we publish on http://www.xwiki.org/xwiki/bin/view/Download/ page and use the refactoring to move XE features to a new platform flavor as a good opportunity for this change. In more details the proposal is the following: * name "xwiki-demo-9.5.zip" or "xwiki-9.5.zip" the standard jetty/hsqldb package (the one which let you choose the flavor you want to install) * name "xwiki-9.5.war" the standard war package * name "xwiki-classic-9.5.xip" the offline package containing XWiki Classic flavor WDYT ? Other ideas ? +1 with a preference for "xwiki-demo-9.5.zip" over "xwiki-9.5.zip" to make it more clear it's not a production oriented package. -- Thomas Mortagne

[xwiki-devs] [Proposal][Glossary Application][Phase-1]
by Sarthak Gupta 06 Jun '17

06 Jun '17

Hi everyone, I would be working on the proposal 'Glossary Application' in the coming days. The details of the proposal can be found on the Design Page <http://design.xwiki.org/xwiki/bin/view/Proposal/GlossaryApplication> . Please tell me if something is not clear. Any suggestions are welcomed. :) I wanted to propose a UI for both the pages ('HomePage' and 'glossary page for each item'). - For the Glossary HomePage: - A search bar will be employed on the top of page, which would search a glossary page(from glossary space) if a user enters the matching words for that glossary items. A search bar will be made using HTML/CSS. - The search results (suggestions) will be displayed on the same page below the search bar along with the location of the glossary item.(considering the fact that two glossary items with the same name may exist). I saw that there is a 'Suggest Widget' for this. Hope I can make it work :P . - On clicking those links, the user will be directed to the matching glossary page. Is this UI ok? - Glossary Page of each glossary item: - It will contain two fields. - First field will be a 'String' which will contain the name of the glossary item. - Second field will be a 'text area' named "Glossary". It will contain the glossary of that item that a user will enter itself on the page, he is on. Is this UI ok? After this I will update my design page and tell you about my next steps.....! Thanks :) Sarthak Gupta [sarthakg]

[xwiki-devs] [Gsoc][Update] Red Pen Integration UI
by deshengchuan 06 Jun '17

06 Jun '17

Dear all, an update with the activities regarding the red pen integration. Red-pen side implementation: As of now I am unable to establish contact with neither the community and redpen, nor with its creator, Mr. Takahito Ito. Their community seems to be quite silent, unlike ours Hence, I will be beginning preliminary design on the UI. As of now I am planning to create the UI something like the FAQ page. Each entry on the page by the user corresponds to a particular Red-Pen Validator setting which for now would be imported into a Redpen server (As of now I will use my localhost terminal to set up the server). I am dealing with the import of the validators from the ui into the server first, before incorporating the ScriptServices that will call the dependent components which will do the proofreading. What do you think? P.S. Sorry for the absence over last week, by some bad coincidences I had 2 48-hour hackathons back to back. -- View this message in context: http://xwiki.475771.n2.nabble.com/Gsoc-Update-Red-Pen-Integration-UI-tp7604… Sent from the XWiki- Dev mailing list archive at Nabble.com.

[xwiki-devs] Status on jenkins work and experimentations
by Vincent Massol 03 Jun '17

03 Jun '17

Hi devs, I wanted to share with you what’s been done and what’s next, related to the CI improvements and especially jenkins pipelines. Done: ===== * A) Share pipeline script is configured on ci.xwiki.org and available at https://github.com/xwiki/xwiki-jenkins-pipeline * B) Contrib projects are using a Jenkinsfile and a Github Organization job is set up on ci.xwiki.org (automatically create and remove jobs based on branches and PRs) * C) The share pipeline script now supports screenshot attachment to the job test report page + avoids false positives emails Ongoing experiment: ================ * D) I started moving the commons/rendering/platform/enterprise jobs to use our pipeline script but this is not possible right now because there’s an important missing feature ATM in pipeline: the ability to have incremental maven builds (ie only rebuild the module touched by the commit and its dependencies). Without this we would rebuild the whole repo which would lead to more load on the agents and slower feedback times. What I’m planning to work on next: =========================== * E) Create a new pipeline script to perform releases of XE (commons + rendering + platform + enterprise). The idea is to move part of our release script into a pipeline that would get executed either at each commit (if we have enough agents) or once per day or more. The idea is that once we’re ready to cut the release we could just promote the pre-built release and win several hours on our release process. This is what’s left to do in order to be able to do this IMO: ** Set the “xwiki.compatibility.previous.version” automatically in the script if not correct (this is step 1 of the release plan) ** Move the translation script into the pipeline script and only apply translations for non bug fix releases. Note that the RM would still need to validate visually that no spam was introduced in translations at release time by reviewing the job logs. ** Create a flickering “database”, either in jira or in xwiki.org (my proposal is to use xwiki.org and have an XObject per flicker), and in the pipeline script verify automatically that any failing test is part of the flicker database or fail the release otherwise. ** Execute the release:prepare and release:perform goals in the pipeline script and release to a staging nexus repo on nexus.xwiki.org. The RM would just need to release from this repo at release time ** Have some nexus scheduled task to remove non-released staging repos, or do this using the nexus REST API inside the pipeline script if need be (or do this manually by the RM initially) * F) Experiment using the docker pipeline feature to run XWiki functional tests inside docker. The goal is to be able to test xwiki in various setups (various DBs, with LibreOffice server, ideally clustering but that’s harder, etc). ** For this I think I’ll need to develop a new docker image that doesn’t include XWiki and map the local directory where the XWiki distribution has been created by the packager plugin into the docker image. If you have any remarks please let me know and if someone is interested in participating let me know too :) Thanks -Vincent

[xwiki-devs] [XWiki Day] Test Day #7
by Thomas Mortagne 01 Jun '17

01 Jun '17

Hi devs, The idea today is to do a Test Day with priority to fixing long standing flickering (integration mostly) tests. You can find known flickering tests on http://jira.xwiki.org/issues/?filter=14240. The goal is to really fix them, not just add some random wait here and there ;) If you are not confident with the area around those specific flickering tests here are some other ideas for today: * obviously add more tests and increase the code coverage * move tests from enterprise to platform. Needed for the platform flavor and removal of XE * update jacoco covering setup (we often forget to increase it when adding more tests) * move more tests from JMock to Mockito * work on new test setups and tools: ** improve docker containers for packaging XWiki (possibly several for multiple DBs and Servlet containers). ** work on spreading Jenkins platform job into one job per maven module so that build can be spread on various agents (groovy scripting) ** Research/Use Jenkins 2 Pipeline plugin with the new DSL and commit the jenkinsfile in SCM ** Test platform to run contrib extension tests on various versions of XWiki automatically * Speedup existing tests (research xwiki startup time, remove unnecessary modules, etc) When what you fix can be linked to a Jira issue (sure you can create a jira issue for adding new tests this time :)), tag it with "testday" (same idea as "bugfixingday" when doing BFD). If not then answer to this mail to explain what you did. Good Test Day !

[xwiki-devs] Using tables and classes
by andreea avram 01 Jun '17

01 Jun '17

Hi, I created a xclass with more attributes which represent the columns of a table. I need to write data in that table and also to get data from the table such that i will can compute an average for example (with that values) and after that i want to put/write the result in the same table. The page I have created using the xclass contains the attributes of the xclass, which I can modify, but I need the table. So, my question is: How can I make the table such that I will can write in it and get data from it? Also, how can I export that table as pdf document?Thank you! | | Virus-free. www.avast.com |

[xwiki-devs] [GSoC] More extension repositories
by Krzysiek Płachno 01 Jun '17

01 Jun '17

GSoC Coding Part Finally starts tomorrow, so the highest time to get down to work. I created modest design page where I put summary of general idea of my project: http://design.xwiki.org/xwiki/bin/view/Proposal/Moreextensionrepositories To start coding I need: 1. A confirmed naming pattern for the extensions that I will develop. My suggestion is "..... Integration" e.g. "Pypi Integration" "Bintray Integration" Imho, the names of possible repositories are popular and verbose enough to impy that the integration is about extension repository. What do you think? 2. Repositories on https://github.com/xwiki-contrib One per each extension (i.e. external) repository: Bintray, Pypi, NPM. Is it enough if I ask for it here or should I create some official request? 3. Some space somewhere in XWiki ecosystem where I would be able to document progress and decisions made - things much more detailed and low-level that are normally presented on design pages or http://extensions.xwiki.org/xwiki/bin/view/Extension/ pages. Best, Krzysztof Płachno

[xwiki-devs] [Brainstorming] Notifications sending email
by Guillaume Delhumeau 01 Jun '17

01 Jun '17

Help me to decide! TL;DR: * I need to know if performing a query on the database for each user who want to receive an email with all the notifications, is a scalability issue (in a job context). * If it's not an issue, I can implement the "naïve" solution which requires less development. Full message: Status: * notifications are displayed on the top menu when you browse the wiki. * notifications are displayed differently for each individual user according to their preferences (filters on event type, on locations, etc...). * similar notifications are grouped together into "composite notifications". * there is only a few notifications displayed (5 by default). Objective: * send an email periodically (every hour, every day, every week) according to the user preferences with ALL events that happened during the last period of time, but still according to the user preferences. Inspiration: * the watchlist gets ALL events that happened during the last period of time * then, for each user, remove the events which the user is not interested in * Benefit: only one query to get the events from the database for all users Problems: * in the notifications, I have introduced a NotificationFilter role the make possible to inject some SQL in the query to get the events according to the user preferences. I call this "pre-filters". ** it means we generate a unique request for each individual user, so if we send a mail to 1000 users, we will have 1000 requests to the database. I wonder if it's a non-problem or a big scability issue. Because even if the whole job that send emails take ~10 minutes, it does not matter. It's not a realtime thing. For the records, NotificationFilter have "post-filters" too, that perform check on the event itself (for example checking the permissions, etc...). Alternatives: * just like the watchlist, perform a very generic query on the database to get all the events that happened during the last period of time * then for each user, use only the "post-filters" to remove events the user don't care of Problem: * it means the pre-filters that make sense in the notification use-case cannot be used for emails. Developers must be aware of this. * it requires some refactoring of the code that group similar notifications. Question: Should I go with the "naive" solution, ie for each user get all notifications and send a mail, or should I go with the "only 1 query to the database for all users" version?
