[xwiki-devs] Jira not showing Git logs anymore?

by Paul Libbrecht

Hello fellow developers, we used to see Git commits linked to jira issues (in the activity I think). I was expecting one here: http://jira.xwiki.org/browse/CURRIKI-6545 e.g that commit: https://github.com/xwiki-contrib/currikiorg/commit/b56edde328aabb19e5874fdc… Was something changed into the jira so that xwiki-contrib is not watched anymore? The feature seems to be still there for xwiki-platform. thanks in advance. paul

[xwiki-devs] Refresh a macro

by firmusoft.xwiki

Hi, I have a macro which displays all the objects of a class in a table. We can add a new object to the class also, using the macro. I want the newly added object listed in the table. Currently this happens only when I reload the page. Can we refresh a macro so that the table gets updated as soon as we add a new object? Please help me on this Thanks, Firmusoft

[xwiki-devs] [Brainstorming] Applications / Skin dependence

by Ecaterina Moraru (Valica)

Hi, With the new Flamingo skin and with the design investigations done on existing Applications, there are more and more questions related to: * how will the applications be displayed on the new skin, while conserving the same look on the old skin; * how much an application should preserve previous functionality and how many efforts are we putting in adapting the functionality for new layouts; * when do we create a new application vs. when do we retire one; * etc. This question applies in general to applications and you can also read some discussions about applications like Panels [1] or ColorThemes [2]. In this thread I want to discuss some variants related to application's presentation: http://design.xwiki.org/xwiki/bin/view/Proposal/ApplicationPresentation#HVa… I am interested in our position regarding this topic and if we have like a 'standard' solution or if the answer depends on the application in cause. Thanks, Caty [1] http://design.xwiki.org/xwiki/bin/view/Proposal/PanelsImprovements [2] http://design.xwiki.org/xwiki/bin/view/Proposal/ColorThemeforFlamingo

[xwiki-devs] Extensions documentation (was:[Proposal] New xwiki-extensions GitHub organization)

by Jeremie BOUSQUET

Hello, Regarding applications best practices, I noticed that in the list of best practices there's nothing related to documenting your extension, apart from the fact that you should publish it on e.x.o. It's better now, but I think it happened frequently to have pages created in extensions repository with only the default information and a download link, it makes difficult understanding and using the extension. For example for xar, it could be helpful to have at least the list of space(s) created by the app (if any), without having to look into the xar, or to install it with EM. Also in EM you see the pages installed, but only in the logs. After it's installed and you come back, you have no way to list the pages that belong to a specific extension. For an app you could have an entry in app panel, but for a macro for example, it makes it difficult to find the macro afterwards. Obviously for anything proposing an API, the API should be described (at least a javadoc link, better some digest in extension page IMHO). The problem with adding the documentation AFTER publishing the extension (for example, you need to deploy it in a rush, so you don't have time to write proper documentation), is that you risk that users come first when extension is published, see nothing, and never come back. So I really think to have this part of the release process of an extension (and not something added after the time). That's also a problem for example with some Maven plugins (even some officially supported), that propose only very minimal information on their site, and count on source code access and forums to provide essential infos to users... WDYT ?

Yes I agree about your points. We need to handle this. Now === The new xwiki-extensions organization strategy will work only if we get more committers. The idea is to get the contributors of those extensions as committers for those extensions and thus be the RM for those extensions. Said differently we need a defined RM per repo. Note that longer release cycles is not an issue if the extensions has not had any code committed for it. What’s important is to be able to get it in the hands of users when there are important bug fixes or new features. It seems logical to me that those who commit these bugs/features release them. It’s obvious that separated extensions would mean a lot more work *if* we wanted to always release them all. But this is not the case. They’ll be released when those working on them want to release them or under user pressure. What we need to decide is how we want to handle Roadmaps and Release notes. I think we should start defining roadmaps per extension on e.x.o (we already support RN on e.x.o using either the jira macro or manually). Generally speaking for each extension that we add to xwiki-extensions we need a person resonsible for it, who’ll be in charge of defining the roadmaps, release notes and do the releases (he/she can delegate but he/she will still be responsible until that responsibility is handed to someone else. I believe this will be one criteria for accepting an extension in xwiki-extensions. Future ====== When we have the notion of Flavors, I believe it will simplify things to organize releases per flavor (XE can be considered a flavor ATM BTW). When this time comes we could decide to have a RM per flavor with a Roadmap/Release notes per flavor. I have no idea how many flavors we would have but I can think of 3: - xwiki.org flavor (FAQ app, JIRA macro, IRCBot app, etc) - knowledge base flavor (…) - collaborative apps flavor (calendar, meeting manager, file manager, etc) > As for moving extensions out of xwiki-contrib to xwiki-extensions, > it's not simple.

They’ll be chosen on a case by case basis with a VOTE for each. The person proposing it will put forward a maintainer for the extensions (who will be responsible of Roadmap/Releases Notes and performing releases). Note that IMO there are some conditions that we could define as base conditions: * Having had several releases already * Obeying the app best practices as defined by http://dev.xwiki.org/xwiki/bin/view/Community/ApplicationDevelopmentBestPra… * Having some tests and for apps, having at least one functional test (this means the functional test fwk is in place and ready to receive more tests) * Code style needs to obey http://dev.xwiki.org/xwiki/bin/view/Community/CodeStyle and generally speaking obey the practices defined on http://dev.xwiki.org > Then what happens if an > extension from xwiki-extensions stops being maintained, do we move it > back to xwiki-contrib? Yes, same as what happens currently in the xwiki organization. > I'm not fully convinced by your proposal. The real goal of this proposal is to start having nice applications that can be a showcase of XWiki. Till now we have the engine and some extensions but none of them are developed as strongly as platform and they fall short. This is an effort to make a usable XWiki *product* vs just an XWiki *platform*. Again, we should take in only extensions that we can maintain, i.e. for which we have a volunteer to maintain them. TBH I don’t know if this will succeed or not but I feel it’s worth trying :) Do you have some better idea?

[xwiki-devs] [Proposal] New xwiki-extensions GitHub organization

by vincent＠massol.net

Hi devs, Right now we have 2 organizations related to the XWiki project on Github: xwiki and xwiki-contribs. The separation is currently the following: * XWiki Committers maintain the code in the “xwiki” organization * non XWiki Committers (aka contributors) maintain the code in the “xwiki-contrib” organization in the way they want (some extensions there are not maintained, others are maintained) After brainstorming with Thomas Mortagne we’d like to propose the following changes: Need ===== * Be able to extract some maintained apps from xwiki-contrib to separate them from less maintained extensions. For example the top apps listed here: http://design.xwiki.org/xwiki/bin/view/Proposal/CollaborativeApplications * Be able to extract some extensions currently located in xwiki-platform but not released with XE so that they can have a different release cycle (examples: FAQ app, IRCBot extension, JIRA macro, etc). Having different release cycle allow to release new versions quicker to our users (bug fixes, new features). Proposal ======= * Introduce a new xwiki-extensions organization in GitHub which would be maintained by the XWiki Dev Team (aka XWiki Committers) * For now, move out of xwiki/xwiki-platform all modules that are not bundled by default in XE. This rule will be reviewed and modified when we introduce the flavors concept in the future. The idea is that xwiki-platform will contain “core extensions” only and as we progress towards extensions, the number of core extensions will get smaller and smaller till possibly only the EM and what it requires. Everything else would be located in the xwiki-extensions organization * Have one repository per extensions in the xwiki-extensions github organization so that each extension can be released independently of each other * In order to make it simple to release, the idea would be to have Roadmaps and aggregated Release Notes per Flavor (this is what we’re doing now with the “XE” flavor BTW). * We will be able to vote in committers for specific repos located in the xwiki-extensions organization without having them voted for the xwiki organization (although, over time, they would be able to become xwiki committers for the xwiki orgnization should they wish and if they’re voted in) * Extensions from xwiki-extensions published on e.x.o would have “XWiki Development Team” as author, which means they will be officially supported by the xwiki committers. WDYT? Thanks -Vincent & Thomas

[xwiki-devs] The danger of API proliferation.

by Caleb James DeLisle

Hi folks, I saw an issue to rename a method ( http://jira.xwiki.org/browse/XWIKI-10311 ) in XWikiContext. I don't want to single out the author, the commit is not an outlier, on the contrary it represents a pattern and this worries me. I've seen this same pattern in Microsoft technology and while each decision in isolation makes sense, the sum of all changes ended up making Windows an unapproachable API garbage heap which may be one reason why everyone left the desktop to develop for the web. Take for example the humble printf() function, standardized in POSIX. At some point a somebody at Microsoft noticed all of the security problems with C programs and decided to make a set of "hardened" functions which would be more secure. Some of them had excellent security features but others did just a little extra checking, each had the suffix "_s" added to the function name. Because it's not feasible to do any other checks, printf_s() just checks if the inputs are NULL and if so, raises an exception. Developers who had been using printf() were told that they were making bad insecure code and had to begin using printf_s(). Windows was being used in many countries with different alphabets and at the time, the only way to represent different languages was using the high 128 characters left undefined by the ASCII standard, but since each language needed a different 128 characters, Windows needed to know what language the string should be interpreted in so somebody invented printf_l() which took an extra parameter which was the *locale*. Of course printf_s_l() because people still need to write secure code! Eventually this silly idea of locales and code pages was replaced with Unicode (specifically UTF-16). Unicode characters being 16 bits wide needed to be handled differently from their 8 bit cousins so a new set of functions was written beginning with w prefix. wprintf() wprintf_s() and to make porting easier for programs which had been written to use "_l" functions, they added wprintf_l() and wprintf_s_l() even though they should not have been strictly necessary. Unfortunately after everyone had rewritten their programs to use the new and improved wchar_t and the w* functions, someone realized that not all computers even support Unicode! So they rushed to implement a new character type called tchar_t which is a wide character if-and-only-if the computer supports it. When tchar was invented, they had 4 printf functions to port and so came tprintf() tprintf_s() tprints_l() and tprintf_s_l(). Then some smart guy at IBM took another look at this Unicode idea and realized that with clever encoding, one could make a character representation which uses 1 byte to represent ASCII letters and more bytes only when it needed to represent different alphabets. Thus UTF-8 was born. The best part was it was fully backward compatible so you could use this with normal printf()! In the Linux world, most of this drama just never occurred, people kept on using printf() as if the rest of the world never existed and when UTF-8 was devised, Linux programs could suddenly speak Chinese. Microsoft, apparently ashamed of their 11 printf functions but still unable to take a lesson, deprecated them all and went on to create .NET which standardized around Console.WriteLine() (for now). While Linux and friends now all transparently support UTF-8 and it's alphabets, Windows is still unable to support Unicode filenames without first converting the string into wide character format and then using the old 'w' prefixed functions. Even then, UTF-8's scaling byte count supports more characters than UTF-16 so Windows *still* has a hard time with some languages! The problem with all this is you lose coherency, the community fragments and if the scary plethora of methods is not enough to scare off new developers, there are the angry old developers standing by to haze them for using insecure/unportable/deprecated functions instead of the shiny new ones. I think we should think a lot harder before either deprecating a method or adding duplicate functionality. Anyway my 2¢ Thanks, Caleb

[xwiki-devs] How many committers are using IntelliJ IDEA and are happy with it?

by vincent＠massol.net

Hi devs, Our intellij IDEA ultimate license has expired. Jetbrains is ok to renew it but they wish that the xwiki project gives something more in return: they mentioned some blog post for example. So first, who’s using IDEA and would like to continue using the Ultimate version (vs the community one which is free)? Any idea of what we could do? Thanks -Vincent
