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

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

Regards - Steve

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

Index: sw/subversion/src/subversion/mod_dav_svn/lock.c

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?
