[Christian Boos]

Ok, so I verified that there's nothing special with svn 1.6.15, and on your side it seems that svn alone is able to use that repository. I assume svnlook --version gives you 1.6.15 and that this corresponds to the same libraries also used by Trac via the svn bindings for Python.

Could you please try the script check_svn_repos.py​ from ticket #2620? It exercises the svn API in a minimal way, but also depends on the Trac API for the Pool object… The svn calls should however be able to work without that pool object.

So if the problem can be reproduced with that script, can you then try again with the following change:

check_svn_repos.py

@@ -21 +21 @@
 
     def check(self, rev):
         pool = Pool(self.pool)
-        root = fs.revision_root(self.fs_ptr, rev, pool())
+        root = fs.revision_root(self.fs_ptr, rev)
         editor = repos.RevisionChangeCollector(self.fs_ptr, rev, pool())
         e_ptr, e_baton = delta.make_editor(editor, pool())
         repos.svn_repos_replay(root, e_ptr, e_baton, pool())

[Carsten Klein <carsten.klein@…>]

Trying to analyze this bug but I have stumbled upon the following construct in versioncontrol.api:

841	    def get_oldest_rev(self):
842	        """Return the oldest revision stored in the repository."""
843	        raise NotImplementedError
844	    oldest_rev = property(lambda x: x.get_oldest_rev())
845	
846	    def get_youngest_rev(self):
847	        """Return the youngest revision in the repository."""
848	        raise NotImplementedError
849	    youngest_rev = property(lambda x: x.get_youngest_rev())

Should it not rather be

...
oldest_rev = property(lambda self: self.get_oldest_rev())
...
youngest_rev = property(lambda self: self.get_youngest_rev())

to make it more clear that it accesses self?

[Remy Blank]

Cosmetic, but clearer, yes. Fixed in [10719].

[anonymous]

Hello,

I don't think the issue is fixed by applying the cosmetic changes. I am running Trac 0.12.1 with svn 1.6.17 on a QNAP NAS and I am getting the same error when doing a "trac-admin $ENV repository resync myRepos".

The error occurs in fs.py of libsvn, but in my case in line 729, not line 244 as in the orginal post. I assume that is because I am using trac-admin and not access the repository via web interface.

I manually applied the changed described in [10719] , but this didn't help. You described those changes as being cosmetic anyway. So how can the issue be fixed?

Please let me know which further information you need to better analyze the issue.

Probably an InstallationIssue as it works for everybody else… (perhaps some kind of svn libraries mismatch between the bindings and the installed ones?).

See TracTroubleshooting and TracSubversion#Troubleshooting for hints about how you could dig deeper.

Parking the issue as a 3rd party issue…

Closing since this is pretty old.
