A gpointer is a void *, so - it's certainly guaranteed to be at least as large as any other - pointer. And a jobject is implicitly an opaque pointer (in Jikes RVM, we - use small integers, but we coerce them into the representation of a - pointer). - - The int <==> Thread mapping addresses a different issue. I realize that I - did not document this properly (two and a half lines in thread_create), - and the point is subtle (at least to me; took me a while to figure out). - - The int => Thread mapping always returns jobjects that are local - references, not global ones. This is because Thread objects need to be - able to go away and be garbage collected after the thread they refer to - has died. - - If we keep a global object reference to a thread, then when do we delete - that global object reference? We have an answer in the case of GThread - objects that were explicitly created with the joinable attribute. It is - safe for us to maintain a global reference to any joinable thread, since - the joinable thread must linger (even if only in a zombie state) - until it's explicitly joined via a g_thread_join() call. The global ref - could be cleaned up at that point too. - - However, in the case of GThreads that were created non-joinable by - g_thread_create(), and in the case of Java threads that were created - within pure Java code (not via g_thread_create()), we don't want them to - linger forever, and there is no way to tell when the last reference - to such threads needs to expire. In the case of this application -- AWT - with GTK peers -- it would probably be safe anyway, since there are not - very many threads we create, but I was going for correctness even in the - case of long-running programs that might set up and tear down AWT - interfaces many times. - - So, I duplicated the POSIX thread-ID semantics. The thread ID of a - non-joinable thread remains valid as long as that thread is still alive. - Once that thread dies, the old thread ID may be reused at any moment. And - that's why the array indexed by thread ID numbers is an array of weak - references. - - That's also why the int => Thread jobject mapping function always returns - local references, since global references would lock the Thread in memory - forever. - - I would dearly love there to be a cleaner solution.
