Hi Allin,
Thanks for all the great work that you’ve been doing.
There seems to be a bug when there are multiple instance of gretl
working at the same time.
Here is a description of the problem that I’m facing:
Whenever I have more than one instance of gretl open, and if I
closed one of them, then I’m not able to save the .gretl season
file that I have created before. The pattern of the error message
is like: “.myfile/session.xml: No such file or directory”.
Ah, I know why that is. On exit, gretl cleans up the contents of the
user's "dot-directory", where session-files in progress are stored.
So when gretl-2 exits it's going to trash gretl-1's session
directory.
The workaround is, if you're running more than one gretl instance,
don't close a given instance if you've got an active session in
another instance.
We can try revising gretl's clean-up behavior at exit, though that
won't be particularly easy to get right in the multi-instance case.
