Hi, I'd like to release XEclipse 1.0M1. Release notes: ** New Feature * [XECLIPSE-1] - Navigate the Documents tree and viewing XWiki pages. * [XECLIPSE-2] - Delete existing pages/spaces * [XECLIPSE-3] - Login to xwiki from Eclipse and import spaces selectively * [XECLIPSE-9] - Edit and Save pages * [XECLIPSE-10] - Add new pages/spaces ** Task * [XECLIPSE-11] - Clean up source code and apply XWiki development practices * [XECLIPSE-12] - Create Maven2 build for the Eclipse integration * [XECLIPSE-20] - Write a quick installation and using page for XEclipse * [XECLIPSE-25] - Move XEclipse to xwiki-extensions/ and out of the Sandbox Here's my +1 The list being down I'll take the risk of releasing it without more votes... I think we have already all agreed we wanted that release to happen ASAP. In addition, I've pinged on IRC and I got 3 +1: - Sergiu - Catalin - Stephane Thanks -Vincent

[Proposal] Document comments should not create new versions

by Sergiu Dumitriu

Hi, This is more a matter of opinions. Should a comment increase the version of a document? I'd say yes, but the view of simple users is that a comment should not affect the document, as it is something describing the document, not belonging to the document. So we should have a parameter that configures this. WDYT? Sergiu -- http://purl.org/net/sergiu

Use Swizzle directly or use a facade (was Re: XEclipse 1.0M1 will only work for xwiki-core-1.1M4 (but not for xwiki-core-1.2-SNAPSHOT))

You didn't spend even 1% of the time it took to create Swizzle as it is today and if you think about how swizzle will evolve in the future that percentage drops down to 0.01%. This is why I thought this should be stressed out :) [snip] >> * If swizzle goes away or is abandonned then it'll be bad for >> xwiki and we'd >> need to support it/reintegrate it. >> > First, swizzle is open source so can't "go away", we can always > continue to maintain it. That's harder than you think. Radeox went away and are we maintaining it? Nope. Of course we can always say that it's because its architecture was too limited, etc but had it been maintained its architecture could have evolved too. The same would happen with swizzle if it goes away IMO. But it's not only an issue of Swizzle going away because it's abandoned. Imagine a competitor project appears and it's better than swizzle for XWiki. How do we tell all our users that they have to redo all their client code. We won't and thus we probably won't move to this better project because we have standardized on Swizzle. It's about having a stable client-side interface. I much prefer the approach where we define our model objects (we need them anyway on the server so it may even be possible to share some of them on the client - Not sure about this but it's a thought) and our interfaces and we keep the implementation separate. I'm 100% for implementing those interfaces with Swizzle. In addition we need to offer a XWiki-specific API so instead of offering several remoting APIs I propose we offer only one. Then it's up to the implementations to implement them. The confluence implementation (using Swizzle) could throw NotImplementedException for stuff it doesn't implement so that client code using it will be 100% confluence-compatible if that's the user's desire. And we would be able to have a single unified API that has all the XWiki-specific stuff. > And if it ever goes abandoned how would this > be any worse than what we have now?

However, why can't we provide interfaces as part of the > swizzle project ? Why can't we make swizzle more component-friendly by > just changing it? Why would we need another XWiki-specific wrapper > layer? Swizzle is not our project. We could become committers to it of course but I assure you it's still going to be 100 times more difficult to evolve Swizzle than to evolve XWiki code. For 2 reasons: * We "own" XWiki. All committers on XWiki are interested by XWiki only. * Swizzle has to stay generic and making a generic change is always more difficult than making a specific change. The same applies to the fact that Swizzle if confluence-specific. Regarding the confluence-specific, it bothers me that the only remoting interface we're providing is confluence-specific and has confluence written all over. I think we should offer a XWiki-specific API and let the user choose the implementation he wants transparently (confluence or not). > One advantage I see of improving swizzle rather than hiding it away is > that this way we are guaranteed(!) to stay compatible with confluence > on the common features.

XEclipse 1.0M1 will only work for xwiki-core-1.1M4 (but not for xwiki-core-1.2-SNAPSHOT)

by Catalin Hritcu

Hello, Until now I have refrained from making API breaking changes in XML-RPC in order to keep compatibility with XEclipse. However, these changes are necessary and cannot be delayed forever, so after the release of XEclipse 1.0M1 (scheduled for today) XEclipse 1.0-SNAPSHOT will need to be moved to swizzle-confluence. I volunteer to make this change happen in the XEclipse trunk once XEclipse 1.0M1 is released. To sum things up: - XEclipse 1.0M1 will only work for xwiki-core-1.1M4 (and all the remaining releases on the 1.1 branch) - XEclipse 1.0M2 will only work for xwiki-core-1.2M1 or later WDYT ? Catalin

[VOTE] Commit Eclipse integration source code and give Commit rights to it to Tharindu and Asiri

by Vincent Massol

Hi, I'd like to commit the eclipse integration source code in a xwiki- extensions/xwiki-eclipse directory. Of course Tharindu/Asiri shoud clean up their code and align it with XWiki's coding conventions first and I won't commit anything until they do so. I'd also like to give them commit access to that section of our SVN (and NOT as general committers). Here's my +1 to both topics. Please cast your votes. Thanks -Vincent

Creating a SVN externals for Curriki

by Vincent Massol

Hi, I've had a request to create a svn external for curriki since they want to use the 1.1 branches from now on. I'm going to create it in [root]/externals/curriki-devs Would be nice to move our trunks-users and trunks-devs there too but I fear this may cause issues so I'll leave them where they are for now unless someone has a better idea. Thanks -Vincent

Strategy for FAQ handling

by Vincent Massol

Hi, Just wanted to explain my current strategy for FAQs on xwiki.org. Whenever I review FAQ pages I do the following: 1) Check if there's a page in the wiki that discusses the question mentioned in the FAQ page 2) If there is, remove the FAQ content and instead link to that page. If there were more information in the FAQ entry, move that information to the page proper 3) if there isn't, then create a new page, in the user guide, dev guide or admin guide and then go to step 2. IMO this is the best strategy for the best of both world: 1) Have a comprehensive documentation 2) Prevent duplication 3) Still keep the FAQ entries so that people can find them easily using google or the wiki search and then get directed to the relevant documentation page. All help is welcome! Thanks -Vincent
