*nrepl-server* buffer disappears after cider-restart

[cch1]

The nrepl buffer disappears after a cider-restart or even a cider-quit followed by a cider-jack-in. Very annoying, and the only solution (that I can discern) is to quit emacs and restart.

This problem has been happening for a while, and is definitely still happening with 0.8.2-SNAPSHOT.

Issue #818 details another problem with the nrepl buffer not scrolling -a desireable enhancement.

I'll have a look at this, although I can't imagine what might go wrong there - after all the restart simply stops everything and starts it again. Btw, this buffer is present only for local connections created with cider-jack-in as it's the buffer of the lein repl process (not the actual nREPL connection).

Not going to happen. As I've said several times - the appearance of the output there is a bug and we should solve it instead.

I noticed cider-restart misbehaved if invoked outside the directory of the project, but other than that - restarts seem to work fine for me.

I think this can be safely marked as duplicate of #732.

nrepl-server is associated with connection, so when connection is closed it's natural to close the nrepl-server buffer.

The real question is if it would be meaningfull to reuse the nrepl-server on restart. I think it is. It is also meaningful to reuse the current REPL buffer. I would even like to have REPL buffer preserved on cider-quit, so I can start a new connection within that buffer.

I'd accept a PR implementing this, but there should also be an option to close the REPL buffer on quit.

This fits into my plans of refactoring Ciders's connection and REPL management as a whole. We have discussed this on multiple ocassions so far. I am waiting for you to pull #903 and for 0.8.2 to be released before I start with it. The changes will touch quite a bit of code, and I don't want to pile commits and then fix conflicts after each minor change to the mainstream. Any ideas of when 0.8.2 could be out?

0.8.2 is stuck on a single issue #885. Hopefully I'll be able to debug and fix it this week, but I won't mind it if someone beats me to it.
