I've seen this issue reported in various mailing lists without solutions (including the 2006 archives of this list!). Recently I found an answer and wanted to add it to the mailing list archives:
Problem: > % svn commit -m '' > > I get the following error: > > > svn: '/d0/home/tlm/path_to_some_dir/Project' has no > ancestry information Resolution - From http://victorhurdugaci.com/svn-no-ancestry-information/: It seems that the SVN commit is forbidden if you try to commit a file that is a folders structure, and one of the nodes in it (not the top most parent) is missing the .svn folder. - folder1 [with .svn] - folder2 [without .svn] - folder3 [with .svn] Committing “folder3″ will bring that error message. In my case, there was a stray .svn in folder1 after I rearranged my workspace. Removing it solved the issue. (SVN client 1.6.6) neil.
