Subject [PATCH] some notes for STATUS that I don't want to forget
Date Mon, 24 Sep 2001 07:16:34 GMT
Here are some things I've either been meaning to do or thing that I
just don't want to forget about.

+    * Currently it is difficult if not impossible to return a proper
+      status code from a thread using apr_thread_exit(), since the
+      value must be a (apr_status_t*), but the pool where this would
+      normally be allocated is in that same function immediately
+      thereafter destroyed. Simply changing the type of this parameter
+      to (apr_status_t) should solve the problem (along with some
+      internal changes in apr_thread_join() to accomodate).
+        Status: Aaron is working on this.
+
+    * There are some optimizations that can be done to the new
+      apr_proc_*() functions (on UNIX). One that may reduce pointer
+      indirection would be to make the apr_proc_mutex_unix_lock_methods_t
+      first-class members of the apr_proc_mutex_t structure.
+
+    * Condition variables are tricky enough to use, and even trickier
+      to implement properly. We could really use a better test case
+      for those subtle quirks that sometimes creep into CV implementations.
+
+    * Once we are fully satisfied with the new lock API, we can
+      begin to migrate the old API to be implemented on top of the
+      new one, or just decide to get rid of it altogether.
