With this, you are stuck with employing a context manager model only. You loose the flexibility to do explicit acquire_read() or acquire_write(). My latest patch has methods shared_lock(), exclusive_lock() that return proxy lock objects that can be used like context managers like you describe, but you still have the flexibility of using the lock manually.
As for the bikeshedding, let's look at the list of concrete implementations out there: Windows: SRW locks (slim reader writer) http://msdn.microsoft.com/en-us/library/windows/desktop/aa904937(v=vs.85).aspx Pthreads: rwlock_t (reader/writer) http://publib.boulder.ibm.com/iseries/v5r2/ic2924/index.htm?info/apis/users_86.htm Java: ReadWriteLock, http://docs.oracle.com/javase/1.5.0/docs/api/java/util/concurrent/locks/ReadWriteLock.html Am I missing anything? Don't see why we need to adopt a completly different name or idiom to what people are used to. Also, note that the java version is quite similar to Richard's proposal. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue8800> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
