[ruby-core:88141] [Ruby trunk Bug#14945] [PATCH] thread.c (blocking_region_end): clear ubf before unregister_ubf_list

Issue #14945 has been reported by normalperson (Eric Wong). ---------------------------------------- Bug #14945: [PATCH] thread.c (blocking_region_end): clear ubf before unregister_ubf_list https://bugs.ruby-lang.org/issues/14945 * Author: normalperson (Eric Wong) * Status: Open * Priority: Normal * Assignee: * Target version: * ruby -v: * Backport: 2.3: REQUIRED, 2.4: REQUIRED, 2.5: REQUIRED ---------------------------------------- thread.c (blocking_region_end): clear ubf before unregister_ubf_list If we keep ubf set after unregistering, there is a window for other threads (including timer thread) to put this thread back on the ubf_list right away. Entering ubf_list unexpectedly after GVL acquisition may cause spurious wakeup and trigger unexpected behavior. Finally, clear ubf before acquiring GVL, to since ubf is useless during GVL acquisition anyways and we don't want to waste cycles in other threads calling ubf for useless work. I found this bug while rewriting GVL to handle timer-thread duty and eliminate separate timer thread. ---Files-------------------------------- 0001-thread.c-blocking_region_end-clear-ubf-before-unregi.patch (1.56 KB) -- https://bugs.ruby-lang.org/ Unsubscribe: <mailto:ruby-core-request@ruby-lang.org?subject=unsubscribe> <http://lists.ruby-lang.org/cgi-bin/mailman/options/ruby-core>
