Distributed testing rsync does not maintain file mode
For distributed testing when using the rsync dirs it does not maintain the mode of the files that are being rsynced.
So if my original file has -r-xr-xr-x it ends up -rw-r--r--
On the remote host it is then unable to execute a file as a subprocess:
E OSError: [Errno 13] Permission denied
I suspect that it should likely use something equivalent to rsync -av --delete /my/local remotehost:/my/remote
That way it should be an exact image of what is on the localhost where py.test runs.
