RE: Possible bug in SVN 1.8.3 and 1.8.4 - file locking

Ah - with a bit of digging around the binary libraries, I can see that it looks like subversion was still built using vc6, and apache using a mix of 2008 and/or 2010.

This being the case, I'd say that this is a prime candidate for what's causing the problem (based upon the comments in the second link)...

So it's not a problem with Redmine or with apache - but it >is< a problem when the binaries used aren't built using the same version of compiler (this is all theory at the moment of course)

All of the Apache and Subversion binaries came from the Bitnami download. I could ask their support people exactly what compiler was used if you think that would help? Anything else I should be asking them at the same time?

Thanks for your time on this

I can generate this error with the 1.8 client by patching mod_dav_svn to return 400:

A trunk client gives a better error:

   svn: warning: W160040: No lock on path 'f' (400 Bad Request)

The question remains why are you getting a 400 Bad Request from the server. As far as I am aware this has only ever been observed by people using Windows and I think it could be an incompatibility between the way Apache and Subversion are built. In this discussion:

http://subversion.tigris.org/ds/viewMessage.do?dsForumId=1065&dsMessageId=894838

a patch/rebuild is reported to fix the problem but the person producing the patch realises that the patch does nothing. Therefore what solved the problem was the rebuild, not the patch. In the same discussion:

http://subversion.tigris.org/ds/viewMessage.do?dsForumId=1065&dsMessageId=905320

somebody else reports a similar incompatibility which was solved by using different binaries.

Do you know how your Apache and Subversion binaries were produced?
