Up to now I've been taking advantage of all the interactive goodness that the IDE offers, but of course that will mostly go away once the app is deployed. But it occurred to me that I could use the "screen" program to keep a REPL around for debugging the live app. My question is: is this a wise thing to do? Are there potential unexpected negative consequences of deploying an application this way? Security holes? Possible crashes? Has anyone tried this? This is one set of lessons I'd rather not learn the hard way.
On my blog (uxul.de) I did exactly this, with SBCL. However, I ran into
the problem that if something elementary that Hunchentoot does not catch
goes wrong (OOM, etc.), the REPL of SBCL will drop me into ldb, instead
of just stopping (so I can restart it externally). As I do not know how
to prevent this, I do not use the REPL anymore.
(As a side note, I prefer using tmux instead of screen. It comes from
the OpenBSD world and is _really_ stable.)
