[Gbbopen-developer] portable threads on sbcl 64bit linux tests fail with pristine source

[Antony Sequeira]

Hi
I am interested in using the portable threads package.
Downloaded the current tar and tried to run the
source/tools/test/portable-threads-test.lisp

I had to make a few changes before that was successful.

I changed all uses of
most-positive-fixnum
to some large value that fits in 32 bit

The use of most-positive-fixnum to the sleep call returns immediately
so tests  that relied on 'sleep for a loooong time' failed

The use of most-positive-fixnum in
(let ((cv (make-condition-variable)))
			  (with-lock-held (cv)
			     (condition-variable-wait-with-timeout cv most-positive-fixnum)))

causes
The value 1152921504606846975 is not of type (UNSIGNED-BYTE 29).
   [Condition of type TYPE-ERROR]

The second change was to reduce the thread count in
  ;; Do spawn and die timing:
  (let ((iterations
         ;; Spawning in OpenMCL is slow (10K works, but we don't want to wait)
         #+openmcl
         1000
         #-openmcl
         100)
;;         10000)

cause at 10000 my machine froze up.

I guess the most-positive-fixnum has to do with the 64 bit and sleep
and timeouts don't seem to like that.
I am not sure why the spawn and die kills my machine (not sure exactly
what happens, just i loose connection and can't connect back on my
ssh, the machine is headless)

Also some tests that I can  see taking quite a few seconds to
complete, come back reporting 0 (or 0.0) seconds instead.

Thanks for providing this work free.
I hope my report helps in some ways.
I do not have much experience with CL and am glad to find this lib.
