[Unison-hackers] Problem with error setting a watch

[Marcos Athanasoulis]

Hi,

I am having an issue.  I replicated it with the following basic setup:

Server 1:

/ssd/unitest (directory being synced and watched)

Server 2

/home/unitest (remote directory synced and watched

If I create a new directory (in this example test1) on
server2://home/unitest/test1

The directory is properly synced back to server 1, but an error is
generated when trying to put a watch on the directory:

[2015-01-28 19:16:14,548 pyinotify ERROR] add_watch: cannot watch
/ssd/unitest/.unison.test1.70cf75d5f3a77222c5327ba3780dce0e.unison.tmp
WD=-1 Errno=No such file or directory (ENOENT)

And the directory test1 does exist, but it almost seems like it is
attempting to watch the temporary file unison creates and then renames to
the actual file name.  But when I turn on debug I can see (I think) that at
the point it is setting the watch the file has already been renamed to
test1 from the unison.tmp file, which it seems to be trying to set the
watch on (though it does not exist at that point).

This seems like it would be a common use case and I don't see anyone
posting similar issues.  Any ideas?

Thanks so much.  (And sidenote, extremely impressed and pleased with Unison
it has solved a big problem for me!)

I am on CentOS 6 (up to date) and Unison 2.48.3.

Here is the whole update session with the failure:
