I just looked at the C code implementing multiprocessing Semaphore. Removing the negative count restriction there looks straight-forward. I'll include it in the patch or will open a separate tracker item for it. [Charles-François] > POSIX semaphore don't support negative initial value.

The Java API supports negative initial values -- the same Dijkstra's original P() and V(). ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue17374> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
