Lock files are not created or removed

[TonioF]

I tried to run zappend (v 0.4.0) from the command line with

zappend -t out/output.zarr in/*.zarr

Computation failed with message:

Error: [Errno 2] No such file or directory: '.../out/output.zarr.lock'

After I created the .lock file myself, computation worked. After it finished successfully, I had to remove the file which was still there. My processing system is CentOS.

As I write this down, I notice that the lock file stated above is not correct, as it should be within the zarr folder, which it isn't.

One more comment: The file name of my target zarr contained a .

Maybe that has something to do with it.

@TonioF thanks, this is really strange, never seen this problem so far.
Could you please try the same using the Python zappend() function, so we get a traceback.
Btw, a traceback also when using the CLI would be good to have.

The issue was a misleading error message. The root cause is that the target parent directory must exist, out in your case obviously did not.
