Hi all, We do have a "usage race" in SVN that I will commit a fix to in a few minutes. This is mainly to document the problem and maybe get feedback in case I over- looked something.
Situation: * We track merges in properties at the top-level dir (usually the branch / trunk root). To commit a merge, the user must update to HEAD and then commit. TXNs based on older revs will be rejected by lib_repos/commit.c: change_dir_prop(). * Transmitting the merge result may take minutes in the case of a large merge (many files, large artwork etc.). * The commit will still fail if there has been another commit on the merge target while merge commit was transmitted. Problem: As a result, the average time between commits to the target branch limits the size of data you may merge (and successfully commit). Solution: We can't do much about the first and second points in the list above but wc updates after small commits should be much faster. i.e. much less of a limitation. The conflict handling in our commit code will be extended such that simple bubble-up directory changes merge cleanly with property changes on that directory. We verify that the entries in the target directory are still the same as in the txn base modulo some version bumps. That way, the working copy will look like the directory being up-to-date and some of the sub-dirs being updated to an older revision. -- Stefan^2.
