Compilation mode will tell you a compilation is still running and
ask if
you want it killed. This is not a serious problem for compilation,
although it is an inconvenience. It's worse for something like
psvn,
which relies on being able to know that the svn process has
finished.
In Tramp 2.1.16-pre this was fixed some weeks ago. Do you see a
chance
to test it, using Tramp's CVS repository? This code is not merged yet
with GNU Emacs.
Looks like it works, thanks!
Hmm, I take it back, maybe. It could also be a psvn.el bug, or maybe
it's a bug in emacs' whole system for handling asynchronous processes;
I'm not sure.
See
http://svn.collab.net/viewvc/svn/trunk/contrib/client-side/emacs/psvn.el?revision=37144&view=markup#l1282
This code essentially launches a process and then sets the process
sentinel. What's happening is that -- sometimes only, maybe when the
process output is large enough -- the process sentinel never gets
called. The Emacs documentation isn't very clear on what is supposed
to happen in that case. Is there a race condition between the process
finishing and the setting of the sentinel? If the process finishes
first, is the sentinel still supposed to be called? It seems like the
answer /ought/ to be yes, since otherwise there is a race condition,
and Emacs doesn't seem to give you anyway to set up the sentinel at
the same time as (or before) launching the process.
