Subject svnmucc --revision 0 no longer works when creating a file
Date Tue, 07 Jul 2020 19:43:45 GMT
When I first started using svnmucc, it used to be the case that
svnmucc 'put' --revision 0 would fail if the target file already
existed. This no longer happens.

The previous behaviour was very useful, so are there any plans to reinstate it?

I don't think there is a straightforward way to guarantee the same
behaviour now.

The closest I could get is:

1) get current parent directory revision
2) check if target file does not exist. This is not as easy as it
sounds, as the target directory may have too many files to list
efficiently, and any other file-based command may fail for a reason
other than a missing file.
3) Put the file using the revision obtained in step 1.
AFAICT this is guaranteed not to replace an existing file.

However it may fail to create the file if the target directory has
been updated in the meantime.

It's only safe to repeat the attempted create if the command failed
due to an out of date revision.
So the failure reason will have to be analysed.
