I have refered and did all the things mentioned in ticket:2770. Also verified the repository using the script ticket:2620

its clearly failing at self.pool() in svn_fs.py

any help is appreciated.

Also verified the repository using the script ticket:2620

its clearly failing at self.pool() in svn_fs.py

So the script fails when you try to access rev 1? Can you also provide the stack trace for that error?

I also found a thread on the Subversion list, which suggests a possible cause for your problem: ​SubversionDev:72146.

Please don't forget to provide some feedback here in the case you were able to troubleshoot the issue.

#3586 marked as duplicate.

I'm reopening this, as we don't have yet a satisfactory confirmation that this issue is due to an apr_off_t incompatibility, as suggested in the mailing list thread mentionned above.

Please do report here if you were able to solve the issue by following those advices.

My Subversion and Apache2 had used the different version of apr library. So I recomplied subversion with the save apr, apr-util which Apache2 used, and solved this issue.

[Christian Boos]

Thanks for the feedback. I'll add this information in our TracSubversion page.

I have same problem. The solution is install latest version of subversion.I have install svn-1.4.4 and now its ok.

Using Gentoo, I upgraded Subversion to the latest version available as of time (dev-util/subversion-1.4.4-r4) but that didn't solved the issue.

I had a look at the TracSubversion Troubleshooting section and ran ldd against the binaries, but they all showed the same apr,apr-util version. Finally I recompiled apr apr-util & apache too, and this solved the problem.
