[Beepcore-java-users] deadlocks?

[William J. M. <wm...@ol...>]

Heya, debugging something in beepcore-java and find that
the current ti[ pf the tree will deadlock on the Echo profile
if the payload is larger than one frame, since the receiveMSG 
method wait()'s on the message to complete, but it has grabbed 
the thread so no more data is read in core.

Has this been seen before?

I thought the socket IO had it's own thread rather than running
in the main app thread for Beepd?

Bill,

Sorry, my mistake. I checked in the wrong version of the Echo profile (the
one in cvs is for the new threading model). Try the new version I just
checked in.

The current version in cvs has an thread for each socket but the problem is
that the profile callbacks happen on that thread too so the profile can
stall the library. In the new threading model this is fixed. I haven't
checked the new threading code it yet because I haven't had time to do the
final cleanup, if you would like a copy I can send you the code (as I recall
only Channel.java changed).

Was there a label set prior to the start of the threading changes?

Is there going to be one?
