Here is what I have noticed so far: I've seen indeed some issue with the history. I thought it was limited to having to resave the document to fix it. Resaving may be not possible due to the exception you may get when you save.

I will look into it. I had to add some code specially for handling attachments. I suspect that is what is creating the problems No attachment in my test, just a very small page. The issue is in the way you manage archives.

- Checking out new document from the repository, the document does not have an history at all, and the creator of the document is not set - Checking out a existing document from the repository (reverting a change), cause the history of the document to be somewhat inverted, the current document being 1.1 version and the history containing later versions... (except when only 1.1 version were existing). The document also cause an exception when you try to save some modification to it: Detailed information: Error number 3201 in 3: Exception while saving document Main.TestPage2 Wrapped Exception: Failed to commit or rollback transaction. Root cause [] com.xpn.xwiki.XWikiException: Error number 3201 in 3: Exception while saving document Main.TestPage2 Wrapped Exception: Failed to commit or rollback transaction. Root cause [] at com.xpn.xwiki.store.XWikiHibernateStore.saveXWikiDoc(XWikiHibernateStore.java:638) ... Wrapped Exception: org.hibernate.StaleStateException: Batch update returned unexpected row count from update [1]; actual row count: 0; expected: 1 The change is then recorded in the archive and not in the document, creating the same "inverted" history situation. I suspect it happen due to a discrepancy between the cache and the database, since after a restart, the 1.1 (current) version is no more in the history. - After a restart, I also got some "C" status, which are not documented, and I imagine, means conflict. But since this is just a restart that cause them, this not expected. Looking at the details, this append on groups, because of object GUID changes without any other changes, and it may be unrelated to your application in particular. Interesting. How come would GUID change in groups ? I do not investigate, just noticed that after a tomcat restart, one GUID has changed on all groups.

Indeed this does not seem related to the SVN app. Either this is normal and then we could change the comparaison to ignore such GUID changes. However the GUID is important data. Probably it is not related and would not do that. - At an initial attempt to go back to the list after committing and then updating a new page, it has shown a status of '?' in place of 'M', but I have not reproduced that later :( The only reason to show ? is that either there is a change both in SVN and in the Wiki Does this means C and not "?" ?

OR the status information is not filled in Agree, and I have get that while the status is available, but I was unable to reproduce :( - SVN operations also cause the recycle bin to contains deleted document, is it intended ? This is possible.. I have to check I also have a question regarding the usage of the status field. Why it is required to keep this status ? if needed, why coding it in place of keeping it with each document (in an xobject) ? I thought about that but did not want the SVN application to have any impact on the wiki you want to commit to SVN Well, it would be nice, but it has more than you expect, and the way you get rid of the Tag object could also be an issue, due to the bad way object are deleted currently in documents. Do you really need that status information ?

I've published this application here: http://code.xwiki.org/xwiki/bin/view/Applications/SVNApplication The objective of this application is to bring to XWiki Applications more professional development practices. One of them is the ability to do version management of XWiki applications. Of course XWiki contains versioning but this versioning does not apply accross wikis and makes it difficult to contribute code back to the community. With the SVN application you can now directly contribute code and code updates to the XWiki SVN contrib repository or to any other SVN repository. You can even commit in multiple SVN repositories in the same Wiki. The SVN Application supports: 1/ Compare the Wiki (limited to a list of spaces) with the SVN repository listing - added pages in the wiki - modified pages in the wiki - new pages in SVN - modified pages in SVN - conflicting pages modified in both SVN and the Wiki 2/ Commit in the SVN Repository 3/ Update from the SVN Repostory 4/ Show differences between SVN and the Wiki (in XML) The SVN Application does not provide merging and conflict resolution. The SVN Application normalizes XWiki XML allowing the cleanup the XML to not have the user, the dates, comments. This is necessary to provide concurrent development on multiple XWiki server without telling you that the pages have changed all the time. The source code is of course in SVN at http://svn.xwiki.org/svnroot/xwiki/contrib/sandbox/xwiki-svn/ Ludovic -- Ludovic Dubost Blog: http://blog.ludovic.org/ XWiki: http://www.xwiki.com Skype: ldubost GTalk: ldubost _______________________________________________ devs mailing list devs(a)xwiki.org <mailto:devs@xwiki.org> http://lists.xwiki.org/mailman/listinfo/devs -- Ludovic Dubost Blog: http://blog.ludovic.org/ XWiki: http://www.xwiki.com Skype: ldubost GTalk: ldubost -- Denis Gervalle SOFTEC sa - CEO eGuilde sarl - CTO
