Hi Denis,
Thanks for the feedback and testing

Hi Ludovic,
I have made some quick testing of this application in our sandbox, and I
have discovered weird issues in relation with the document history.
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.
I will look into it. I had to add some code specially for handling
attachments. I suspect that is what is creating the problems
- 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 ?
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.
- 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
OR
the status information is not filled in
- 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

Hi,
If you are following the xwiki comments, you might have seen that I've been
working on an SVN application for XWiki.
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/
