Hi Sergiu, [snip] The tests below should be split into several testXXX() methods for better maintainability (it's also a junit best practice). > > + > + public void testSectionSplit() throws XWikiException > + { > + List<DocumentSection> sections; > + // Simple test > + document.setContent("1 Section 1\n" + "Content of first > section\n" + "1.1 Subsection 2\n" > + + "Content of second section\n" + "1 Section 3\n" + > "Content of section 3"); > + sections = document.getSplitSectionsAccordingToTitle(); > + assertEquals(3, sections.size()); > + assertEquals("Section 1", sections.get(0).getSectionTitle()); > + assertEquals("1.1", sections.get(1).getSectionLevel()); > + assertEquals(3, sections.get(2).getSectionNumber()); > + assertEquals(80, sections.get(2).getSectionIndex()); another test here: testSectionSplitWhenCommentedOutSection() > > + // Test comments don't break the section editing > + document.setContent("1 Section 1\n" + "Content of first > section\n" > + + "## 1.1 Subsection 2\n" + "Content of second section > \n" + "1 Section 3\n" > + + "Content of section 3"); > + sections = document.getSplitSectionsAccordingToTitle(); > + assertEquals(2, sections.size()); > + assertEquals("Section 1", sections.get(0).getSectionTitle()); > + assertEquals("1", sections.get(1).getSectionLevel()); > + assertEquals(2, sections.get(1).getSectionNumber()); > + assertEquals(83, sections.get(1).getSectionIndex()); another one here > > + // Test spaces are ignored > + document.setContent("1 Section 1\n" + "Content of first > section\n" > + + " 1.1 Subsection 2 \n" + "Content of second > section\n" + "1 Section 3\n" > + + "Content of section 3"); > + sections = document.getSplitSectionsAccordingToTitle(); > + assertEquals(3, sections.size()); > + assertEquals("Subsection 2 ", > sections.get(1).getSectionTitle()); > + assertEquals("1.1", sections.get(1).getSectionLevel()); another one > > + // Test lower headings are ignored > + document.setContent("1 Section 1\n" + "Content of first > section\n" > + + "1.1.1 Lower subsection\n" + "This content is not > important\n" > + + " 1.1 Subsection 2 \n" + "Content of second > section\n" + "1 Section 3\n" > + + "Content of section 3"); > + sections = document.getSplitSectionsAccordingToTitle(); > + assertEquals(3, sections.size()); > + assertEquals("Section 1", sections.get(0).getSectionTitle()); > + assertEquals("Subsection 2 ", > sections.get(1).getSectionTitle()); > + assertEquals("1.1", sections.get(1).getSectionLevel()); another one > > + // Test blank lines are preserved > + document.setContent("\n\n1 Section 1\n\n\n" + "Content of > first section\n\n\n" > + + " 1.1 Subsection 2 \n\n" + "Content of second > section\n" + "1 Section 3\n" > + + "Content of section 3"); > + sections = document.getSplitSectionsAccordingToTitle(); > + assertEquals(3, sections.size()); > + assertEquals(2, sections.get(0).getSectionIndex()); > + assertEquals("Subsection 2 ", > sections.get(1).getSectionTitle()); > + assertEquals(43, sections.get(1).getSectionIndex()); > + } > } thanks -Vincent PS: cool for the tests :)

Re: [xwiki-devs] XWiki Error

by Kamna Jain

Nevermind. I figured that the error was showing up because I was logged in as normal user. I logged in as a superadmina nd it worked! I have one Question though, once I configure my wiki to authenticate against LDAP, should it still allow the "Admin" username (Pwd: admin) to log in. Because that does nto happen in my case. Thanks

[xwiki-devs] XWiki Error

by Kamna Jain

"You are not allowed to view this document or perform this action." I get this error when I try to create a new Class in my standalone installation of XWiki. I have another memeber in the team accessing this installation on my system. Is that a problem? Also, we were able to create a class before I made a small change to the core (just added a print statement to a the UploadAction.java) and rebuilt the core and copied the new jar to my WEB-INF/lib folder. Was I supposed to build the Enterprise also? Please advise. Thanks

[xwiki-devs] XWiki syntax, skins, standards compliance, future concerns

by Sergiu Dumitriu

Hi devs, Since I started working on XWiki, I tried as much as possible to make it as standards-compliant as possible, but I didn't see the same tendency from the rest of the team. The question is, do we want XWiki to be an "almost web 2.0 wannabe" project, or "the most 2.0" web application ever? At the dawn of the web, people cared only about the end result, how the page looked viewed in Netscape or Internet Explorer (sometimes "and" instead of "or"). But as the web gathered more attention, and people started to see it as the next big thing, a platform with a lot of potential, other concerns were raised, such as how the inner and generated code looks, how efficient is the page, how "zen" is the interface and the code... All these are part of Web 2.0. Most people tend to think of it as "the social web", but others also think of it as "the semantic web" and "the web of trust", and even as "the web of accessibility" (ubiquitous web). This, however, comes at a price, that of "high quality". Like there are software design patterns, that make the difference between ugly code and good code, the are also Web design patterns, and Web bad practices. While most of the sites are still ugly, although they provide ultra-cool features and are very popular (like myspace), there is an increasing number of sites that are very appreciated by the developers, like CSSZenGarden. I never use a poorly written site, no matter how "cool" it is, unless I have to. Sites like AListApart, PPK, WASP and others keep propagating good practices that each site should use, like separating the content from style and behavior, using semantic markup for the content, and not meaningless divs and spans (or worse, tables), dropping deprecated JS practices like browser detection, document.all, document.write, trying to keep css hacks to a minimum, having a site that looks good and works well without CSS or javascript, and many others. The final goal is to have sites that are efficient, clean, accessible, browser-independent, but in a full-featured browsing mode they provide the same (or better) browsing experience as with any "only looks matter" page. I can give many examples of sites which are so bad that I get angry whenever I have to use them (most of them are sites which people must use, like SNCF, online banking, e-government). They are all colorful and flashy and shiny and rounded, and I guess mediocre IE users are really happy with them, but if I don't use IE and I keep my hand on the keyboard rather than on the mouse, they stop working as expected. The web is a large platform, with different browsers (agents, to be more generic) and different users, and each combination is different. This is why a site must work in any environment, and it must not make assumptions about the user ("the user is doing what I am doing, so if it works for me, it works for anybody"). Doing otherwise is a discrimination, as such a site denies access to many categories of users. In platform/XE we're following some of these guidelines, but that's not the case with other products. Goals: an XWiki product should do its best to ensure that: - works without javascript - works without css - works without images - works with any input method (I don't usually click the submit button, but press enter, so doing something only on "onclick" is bad) - changing the text size doesn't mess the layout - a crawler does not change the content (GET does not alter the database, except maybe statistics) - works from a text browser (links) - looks good enough when read by a voice browser or displayed with braille - looks good on different displays, ranging from old 600x480 desktops to large 4000x3000 displays, 600x800 handhelds and smaller phone displays, 1024x1280 portrait displays, and also when printed An old and false assumption is that a site that respects these goals looks like a plain HTML file good enough to display some text, without any interactivity and no images... No, the idea is to ensure that the site looks good enough without any browser feature, but when such a feature is available (like support for javascript or images) these features enhance the content already available with a new look, or a new behavior. Of course, it is impossible to ensure that everything that is available with javascript/flash is also available without it, but this is limited to very graphical/interactive features, like drawing, games, or animated content, which is usually done using flash. BAD practices: each developer should try to avoid doing any of these: - using style attributes - putting CSS code inside a page - putting javascript inside a page (both in a <script> tag and in onclick attributes) - putting a lot of divs and spans just for formatting - using meaningless classnames or ids on HTML elements - using invalid markup or css - copy/pasting some snippet from a web page without checking/cleaning the code; most of these snippets were made in the previous millennium, and use really bad and deprecated practices, and they don't work (good enough) with modern browsers or when combined with other snippets and new frameworks - writing convoluted css selectors While it is acceptable to do something like this locally, in the first phase of writing a feature, it is just for the PoC, and the code should be cleaned before committing. GOOD practices: we should try to have this kind of code in the future: - putting the behavior in an external javascript, and attaching it to the target elements on onload or using XBL - using "alt" for images - keeping the content markup simple and enhancing the content with needed divs/spans from javascript or using XBL So, what does this have to do with the title of this message? Well, I already started simplifying the generated HTML syntax generated by wiki markup, as proposed in another mail. I don't like any of the current skins, as they were all done quickly, on top of the previous one, either preserving the flaws or covering them by adding more rules and making the skin heavier. Unfortunately, the last one, Toucan, although it looks very nice and classy, is a nightmare to modify (and sometimes even to view, in Firefox for Ubuntu users, for instance, where it freezes the browser). I think everybody would be happier with a cleaner skin, not a more convoluted one. The way it is now it is very fragile, lots of bugs discovered since the first version, most of them because of some improper CSS rules. Fixing something sometimes breaks something else, like it happens in the current WYSIWYG editor, and we all agree that the editor is bad. And instead of reducing the size of the stylesheets, so that it would be easier for other people to change the skin, we now have a huge file where users easily get lost. Also, we had to disable the CSS validation because of some invalid CSS rules that cannot be removed because they are at the core of the skin IE compatibility. That could have been ensured in a different way, as albatross shows. Relying on browser hacks is very bad. So, what can I say about XE: - The markup is mostly OK, with some minor problems - The JS needs to be cleaned, as we're using some old snippets that are very poorly written; all the code should be upgraded to use prototype - The CSS used to be of medium quality in Albatross, but now is of poor quality in Toucan - It works pretty good without javascript, css or images (some problems with white text on white background without images) and works good from a text browser I know that it is time consuming to ensure the quality of the features, and clients need features more than quality. Still, are we willing to have products of poor quality? Vincent has been trying to improve the quality of the java code, and it annoys him when people are not doing anything to improve this quality by not committing tests, or breaking the checkstyle, or introducing regressions. Well, I feel the same when people commit invalid markup, forms with "onclick" submission, invalid CSS, deprecated javascript... Unfortunately we don't have a checkstyle tool for the interface, that would automatically break the build when people do bad commits. We have the validation checks (and one had to be disabled), and that's the best we can do for the moment. Maybe later we'll be able to write a test that checks if there is any inline javascript or css, or the complexity of the HTML markup (like a maximum depth and forbidding too many imbricated divs). I'm sorry if this message hurts somebody, I'm not trying to blame people, just pulling the alarm signal because we're going in the wrong direction, and we're going deeper and deeper. We should hire people to work on the QA for the web part, but this kind of skills are hard to find, and there is enough manpower needed for the core or for adding new features, we might not have resources to invest in Web QA. It is hard to introduce this quality requirement in the existing large projects, but it would be better to start new projects with a clean web part in mind. So, what else can we do to improve the quality of the web part? Any ideas? -- Sergiu Dumitriu http://purl.org/net/sergiu/

[xwiki-devs] Date row is sorted incorrectly in search result

by Wang Ning

Hi, I have a question about sorting search result. I think XWiki uses XWiki.Results to display search result. Furthermore XWiki.Results use javascript /xwiki/skins/albatross/scripts/table/tablefilterNsort.js to sort and filter the rows. However, the date row in the search result may be sorted incorrectly. As defined is the XWiki.Results, the Date row format is "yyyy MMM dd at HH:mm". Thus the the date will show like "2008 Mar 23 at 22:25" or "2008 Apr 09 at 16:21". If I sort the date row in the search result in decreasing order, and I expect the result like this: 2008 Apr 09 at 16:21 2008 Mar 23 at 22:25 as Apr > Mar. Nevertheless, the actual result is opposite. After checking the code of tablefilterNsort.js, I found there is no special sort functions in the script. Thus, the date "yyyy MMM dd at HH:mm" is treated as a normal string. I think there are two way to solve this problem. 1. change the date format. don't use Apr. use 04 instead. To to this, you only need to change a word in XWiki.Results. change $xwiki.formatDate($bentrydoc.date,"yyyy MMM dd") at $xwiki.formatDate($bentrydoc.date,"HH:mm") to $xwiki.formatDate($bentrydoc.date,"yyyy MM dd") at $xwiki.formatDate($bentrydoc.date,"HH:mm") 2. Change script tablefilterNsort.js. Add a special sort function for the "yyyy MMM dd at HH:mm" format. I think that's a very small problem. However, I think I should tell you. WDYT Sincerely, Wang Ning

[xwiki-devs] Import / Export Options - Problems with rights

by Glenn Everitt

I think somehow my Group and User rights for Spaces are corrupted. Is there some way to verify a problem in the hibernate tables? I was running Xwiki on a Oracle 9 database which I didn't realize was not supported until reading through the Xwiki Dev maillist. I had many exceptions about clob mapping in the xwiki log even after upgrading to Oracle 10 jdbc driver which should have fixed it. I tried to delete and re-add the Groups but when I re-added the Groups they seemed to already have the rights to the Spaces they had before I deleted them. It seems like the delete Group failed. I want to export xwiki data from Oracle 9 and import it into a new Oracle 10 database. The import would allow me to select specific items to import. So, I tried to use the export Admin function which can successfully export everything but then the import function cannot read anything very large. Even if you increase the maximum upload size , and increase heap size you will still run out of memory on import (my export data was about 45MB). I found jira bugs and mail posts related to this problem. I also encountered: XWIKI-1809 during import. I can use Oracle tools to extract and reload the data but it will reload the same corrupt data that I was trying to fix. I found the xwiki-packager-plugin but it seems to have the same issues as import / export Admin function and seems to be limited to hypersonic db. At least there is a method called shutdownHSQLDB and a comment about needing to figure something out for other databases. Is there some way to validate and fix Xwiki Group / User rights before I extract using oracle? Is there some way to extract a portion of the data stored in the hibernate managed tables? I would like to extract data for each space without any users and groups. I could help on the import / export if it can be fixed but I'm not sure requiring all xwiki data in memory at once can be fixed. Has another approach been discussed? Any suggestions on any of the above issues are welcome. I'd really like to use Xwiki!

[xwiki-devs] XE 1.3.8295 -> Watchlist menu

by [Ricardo Rodriguez] Your EPEC Network ICT Team

Hi, I was wondering why my top menu has not a Watch menu and found this annotation in menuview.vm: ## We're disabling the Watchlist menu for now since the Watchlist doesn't work yet in multiwiki ## mode. Remove when http://jira.xwiki.org/jira/browse/XPWATCHLIST-4 is fixed. As far as I can see in Jira (http://jira.xwiki.org/jira/browse/XPWATCHLIST-4), this issue was fixed by Jean-Vicent in r7914. Please, is there any reason to keep the entry filtered when working in virtual mode or could it be already unfiltered? Thanks! -- Ricardo Rodríguez Your EPEC Network ICT Team

[xwiki-devs] [Important] More stability needed - To all committers

by Vincent Massol

Hi everyone, I don't know if you're like me but I have the strong feeling we should be better at not introducing regressions. One of the goal of XE 1.3 and now again XE 1.4 was more stability and more automated tests. Several potential problems are occurring now: 1) People using XWiki are expecting more stability when they upgrade. This is due to the fact that XWiki is improving in general and more people use it. It's expected that it'll just work and that's a reasonable expectations 2) We've introduced several important regressions for the past *4* releases (login/logout/RMUI/Escapes and more). We're following a bas trend. 3) We've recently introduced several storage changes (Sergiu and Artem) and I haven't seen tests that would prove what was working before is still working. I'm not saying it isn't but last time we made a change to the storage area it took us several months to stabilize it and we cannot do that again. 4) We're committing more code than tests meaning the overall quality of XWiki is degrading :( Thus I'd like to propose that: A) We become very very careful when committing things and we only commit when we can *guarantee* that what we've done is working (with a given level of confidence of course). This can only be achieved through tests being committed at the same time as the code is committed B) We stop putting stuff that are NOT critical in point releases. For example dangerous changes were done in the WYSIWYG editor for 1.3.1 and I'm not confident this was a good thing, and certainly not with so little tests and verifications since we know that whenever we touch that editor we introduce problems elsewhere. C) In general we reduce the number of changes that we commit and instead we focus on tests and stability. This is indeed one of the general goals for 1.4. WDYT? Thanks -Vincent

[xwiki-devs] Script that is run when users want to attach files to an XWiki page ?

by Kamna Jain

Hello, I have been looking out for the code /script that handles the UI and the functionality of the UI for attachments section of an Xwiki page. These are the places I have looked at: 1) com.xpn.xwiki.web.AttachAction.java 2) com.xpn.xwiki.web.UploadAction.java 3) Fileupload plugin 4) XWiki Enterprise\webapps\xwiki\wiki_editor\plugins\attachments.js 5) HTML source code of any XWiki page ! the reason I am looking for it, is to try to see how I can modify the code to allow *selection of multiple files for upload at one time* ! In our application, users ight be required to upload more than 10 files at a time and we do not want them to browse to the file system for every file! If someone can point out anything that might help, it would be great. Thanks
