Hi all,
I've had this unbelievable problem for some time now but I'm sick and
tired of ignoring it! It is literally driving nuts...Due to the nature
of the problem my terminal hangs and Eclipse crashes altogether
(potentially losing work)!
So what is the problem...Well I really don't have a clue! it is pretty
obvious that my code is waiting on something but it only happens when
I've got a dependency on a namespace of mine which uses seesaw. It is
basically my gui...the bad behaviour is exhibited every time I try to
reload my namespace after having opened a JFrame regardless of having
done anything on the frame! I mean the same happens if I open it and
close it straight after!
anyway, I managed to mock the behaviour with a minimal example:
-------------------------------------------------------------------------------------------------------------

---------------------------------------------------------------------------------------------------------------------------
any thoughts / feedback are greatly welcome. I cannot see why such a
standard setup would hang after trying to reload the dummy namespace.
everything reloads just fine as long as i don't show anything on
screen...scary stuff!
thanks in advance...

Just a wild guess, but if something's shown on the screen,
#'draw-tiles will probably get invoked to paint the canvas and it
might end up blocking on the #'curr-game promise.

Hello,
As of the freeze of Eclipse: you're probably using 0.10.1. A problem
of hangs in relation with the way Counterclockwise was talking to the
repl has been fixed in the beta. You could either switch right now to
the beta "channel" ( http://ccw.crand.net/updatesite-betas/ ) either
wait until Thursday, I'll deliver what is currently in beta into a new
stable release (0.10.2)
Sent from a smartphone, please excuse the brevity/typos.

even though I'm not entirely sure what you mean, I can confirm that the
promise is not to blame...I replaced it with an atom and the same thing
happened...Delivering the promise is the very 1st thing happening so I
can't see how it might be blocking...also, the canvas does not react
unless the promise has been realized. After closing the gui I can't do
anything on the dummy namespace...it hangs indefinately...
any other thoughts? I am quite desperate here...
Jim
ps: thanks Laurent, I'll check out the stable release on Thursday. The
problem is that I'm not getting any exceptions so I'm not sure to much
extent the eclipse debugger can help me.

is pretty obvious from the output though that everything is waiting! No
clue what though...

Could you create a small lein2 project on github with what you
previously pasted in this thread correctly spread over files, etc., so
that it's really quick to reproduce the error?
Thanks,
Laurent

The original project is already on github...I just committed the dummy
namespace as well so you can have a look...
so, do:
git clone https://github.com/jimpil/Clondie24.git
cd Clondie24
lein2 repl
(load-file "Clondie24.games.dummy.clj")
(ns Clondie24.games.dummy)
(-main)
then close the frame without doing anything and try evaluating anything
(e.g "(:name details)").
it goes without saying that the same thing happens in all other proper
games as well...
thanks a million for looking into this :-)

Hi Jim, isn't that just due to the fact that closing the Swing frame
kills the nrepl server JVM, but not the REPL client?
Also discussed here:
https://groups.google.com/forum/?fromgroups=#!topic/leiningen/QLcZIK2e5C0
I agree, it's annoying, but not sure how to workaround it? Maybe with
a heartbeat between nrepl client/server with the client closing the
repl session if the heartbeat been missing for x seconds...
Hth! K.

Wow! Unbelievable !
So there is nothing wrong with my code?
After reading this thread, it seems like a serious issue...the entire
repl becomes unusable which greatly limits the interactive experience.
But then,
what happens in Eclipse? the same principle applies? From my experience
with Java I know that eclipse spawns a new VM every time you run a
project....what's happening there? why does eclipse crash completely?
btw, thanks for spotting this :-) ...at least now i can stop fiddling
with my code and start looking for a workaround towards the right
direction. Hiding the frame temporarily, would allow me to at least work
easier. I'll try tomorrow...

Oops! I can use :dispose instead of :exit. If it does what it implies,
it should do the job...

Hello,
As I said, the last version of Counterclockwise, now released as stable 0.10.2, does not suffer from this problem anymore : Eclipse does not hang.
The server, however, does not respond (and that's to be expected), with the "exit on close" version.
I urge you to upgrade your Counterclockwise, if not already done ;-)
Cheers,
