I have an SVN repository (hosted on Dreamhost) with needs-lock set on binary files. It sometimes happen that, while committing files locked and modified by me, the commit fails
Found this: https://groups.google.com/forum/#!topic/subversion_users/wZikmNEubz4 It seems this problem manifests when using an svn 1.8 client and a server prior to 1.6.17: when updating the root folder of a working copy, my locks get broken (regardless of the needs-lock flag).
I downgraded to a 1.7.14 client and the problem does not occur.
