Subject: johnny: how to handle sessions?

I tried to understand how I see work with sessions in Johnny. And I
see problems.

For new attacks I think to use just names. These names would refer to
sessions in some dir in home. I guess this dir is ~/.john .

I'd use dir because gui is not intended to have current dir unlike
john that is called from command line standing in some defined and
reasonable place - johnny is somewhere, not in particular dir unless
we support cwd changes, for instance we could follow passwd file: user
opens passwd file and johnny cd'es into dir of this file.

To restore user opens .rec file in johnny. Johnny reads it and opens
respective passwd file. (Also johnny could set settings like they were
before session creation so user see what the session is.) But it needs
to read and parse session file that is considered bad.

I could imaging other approaches that connect file with its sessions
(by sha1 I guess). But using them Johnny would not support sessions
created from command line.

Will we document session file format? Unlike MJohn that creates its
own sessions always Johnny would support seamless migration between
gui and cli. I guess it is a good feature. OTOH johnny could be viewed
as a viewer for progress that is able to start john but do not connect
this starts with files viewed.

How do you see sessions in johnny?

What should I do before summer end? What will we do later?
