Re: [xwiki-devs] [xwiki-notifications] r10096 - xwiki-platform/core/trunk/xwiki-velocity/src/main/java/org/xwiki/velocity

by Vincent Massol

Hi Sergiu, Thanks for fixing my javadoc :) However our automated refactoring has some shortcomings which I've pointed below. I don't know if we can improve the IDE configuration but it would be nice to try since it generates some code that is less readable than the one we generate by hand.

Also remember that we agreed to use a curly brace on the next line for this case (i.e. when the conditions wraps). In addition I don't like how props.hasMoreElements() is cut. > // Call all components implementing the > VelocityContextInitializer's role. > try { > - for (Object interceptor > - : > this.componentManager.lookupList(VelocityContextInitializer.ROLE)) > - { > + for (Object interceptor : this.componentManager > + .lookupList(VelocityContextInitializer.ROLE)) { > ((VelocityContextInitializer) > interceptor).initialize(context); > } same here for the curly brace. > // Ensure that initialization has been called > if (this.engine == null) { > - throw new XWikiVelocityException("This Velocity Engine > has not yet been initialized.

[xwiki-devs] [proposal] Change the maximum line width in the codestyle to 128 characters

by Sergiu Dumitriu

Hi devs, Vincent said that he wanted to propose increasing the maximum line width for a while, but didn't get to do it yet. And since I want the same thing, I'm writing the proposal. So, the idea is to increase the line width to 128 (or 120? I like 128 better), since: - nice code uses descriptive variable/method names, which tend to be quite long, so many method calls span 2 or more lines - we're past the stage where developers have small displays that can only display 80 (or 100) characters at a time - right now the eclipse settings are at 98 chars, which is quite a silly number, and changing to only 100 is not worth the effort, so while we're increasing it, we can use a larger value Migration plan: - first, change the xwiki-verification-tools (next Tuesday) - we don't want to do a massive update, since it will probably create conflicts with the local changes for each developer, and break existing patches - whenever someone changes a file, he should first do a cleanup and commit the file without code changes, then a second commit with the actual behavior fix - never mix cosmetic changes with actual code affecting the behavior, as it will be hard to review that change - the copyright notice doesn't need to be updated So, everybody agrees? Do we use 120 or 128? -- Sergiu Dumitriu http://purl.org/net/sergiu/

[xwiki-devs] should xwiki revert the attachment name

by Wang Ning

Hi, First, I upload a file named "the open grid service architecture.pdf" to xwiki page. Then I download it from the page. The default target file name change to "theopengridservicearchitecture.pdf" which is not friendly file name. I wonder if we can improve this. Are there big difficulties with attachment store components to do so? Thanks. -- Sincerely, Wang Ning

[xwiki-devs] xwiki dev best practices page problem

by Vincent Massol

Hi all, I see that Ludovic has started this page http://platform.xwiki.org/xwiki/bin/view/DevGuide/Best+Practices+XWiki+Appl… However I think it should be moved to the Draft area. Right now it's very misleading and readers will think that it represents best practices that the xwiki dev team is recommending while it's not. It'll become those when we agree on them and that hasn't been done AFAIK. We could move it to the Draft area or we could start a vote on its content... WDYT? Thanks -Vincent

[xwiki-devs] [Proposal] Introduce new Execution Context module

by Vincent Massol

Hi, I've been thinking a lot about the Container component I introduced and while writing unit tests for some of the new rendering classes I realized there was something not right: it's not normal that the HTML exporter or the rendering module depend on the Container object, and especially on the Request. Thus I'd like to introduce the notion of Execution Context (EC in short). The idea is that the xwiki entry points depend on the environment (Servlet, Portlet, etc) but those entry points create an Execution Context which is then used by the core components, independently of the environment. For example the VelocityContext is now put in the EC and not in the Request object. The Container objects still exist and can be used where required but it's expected that they should not be used since that makes the code dependent on the environment. This solves issue I had with code that don't have a request. I have it done on my machine. WDYT? Ok to commit? Thanks -Vincent PS: BTW this makes it very similar to the current XWikiContext (which is good) with the exception that the Container objects are not located inside the EC but as separate threadsafe variables.

[xwiki-devs] Openoffice sdk client need openoffice runtime to run

by Wang Ning

Hi, I want to develop a component to handle office documents in xwiki. As we discussion before, I want to use openoffice api. I set a openoffice develop environment in my pc running ubuntu 8.04, and learn how to use openoffice api. Yes, The oo sdk is powerful to address office documents, MS doc, MS excel... But there's a problem. AFAIK, openoffice api need a openoffice local runtime or a remote server running openoffice. The whole openoffice runtime is 356M, more or less, so we shouldn't contain it in xwiki release. Hense, I think if we want the office importer run in a computer, the computer should have installed openoffice or configurate a remote openoffice server. WDYT? I need some suggestion. Thanks. -- Sincerely, Wang Ning

Hello devs, XWS 1.1 M2 was originally planned for May 26th. Unfortunately, I have been taken by other projects and could not stick to that date. I give you here a status on what needs to be achieved and new dates proposal. For me, the consequent tasks left to be done for us to be feature closed for M2 are the following: * XWS-7 (Manage groups of administrators & power users). It has been started by Florin. For me it's 80% complete today. Florin will continue to work on it. * XWS-79 (Invitation management). About 50% complete. * XWS-23 Support public registration As for dates, here is my proposal : * 1.1 M2 next Monday (June 9th) * 1.1 RC1 on June 19th * 1.1 RC2 or 1.1 final on June 30th. wdyt ?

[xwiki-devs] XWiki-2006 again (configurable database schema name)

by rssh

Good day community. I want to ask again about XWIKI-2006 issue. http://jira.xwiki.org/jira/browse/XWIKI-2006 Now I find the way to change initialization of hibernate (instead calling of setDatabase in the beginning of each session) for non-virtual mode. [attached as configurated_db_schema_07.patch] Can I ask committers to review one ? (See previous discussion in this mail list http://markmail.org/message/6mtyxwff4ccmn3lk) We have 2 votes for previous patch. We need three [as I remember rules of this game] -- yet one vote, please ;) -- Ruslan Shevchenko GradSoft. http://www.gradsoft.ua
