RE: NOT RESOLVED: SVN copy that worked in 1.8.0 now fails with (424 FailedDependency)

Sorry to dredge up an old thread, but this issue is NOT really resolved properly. (Also, I noticed a post that said that this would be treated more seriously if it was brought up again without the "RESOLVED" tag.)

There's a known issue with the Apache server software (https://issues.apache.org/bugzilla/show_bug.cgi?id=55306) whereby if the directory tree being copied has a lock anywhere in it, the DAV component will send a 424 error. Why a copy should need to be concerned about a lock is a mystery.

The so-called "Resolution" listed in the mailing lists here was simply to break or release the locks. It's not really a fix, just a workaround.

The most recent release of Apache is 2.4.6 from July, but the last activity in the bug report is from October. Any idea when the next release is due? The Apache release policy (http://www.apache.org/dev/release.html) doesn't seem to tell me anything significant about that. (I do realise it's an open source project and therefore dependant on people volunteering their time.)

In the meantime, we will all have to continue trying to remember to unlock files before attempting a branch, tag, or other copy. Either that, or revert to an earlier version of Apache.

The error message was reasonably specific, but it actually points at another bug.

ANY lock seems to work. I was able to reproduce the issue by locking the files myself (and to "correct" it by unlocking the files.

We, too, have unmergeable binaries, so we use autoprops - including "needs lock" properties as appropriate. This applies for even one-person teams (our current default).
