---------------------------------------------------------------------- (0006319) geoffclare (manager) - 2023-06-12 08:55 https://austingroupbugs.net/view.php?id=1731#c6319 ---------------------------------------------------------------------- Here's an attempt at wording that uses "any pending unblocked signals" and has no timing issues. I have kept the "<i>set</i> is not a null pointer" condition from the desired action in order to be able to refer to the signal mask change as a timing point. A side-effect of this is that if pthread_sigmask() is used just to obtain the current mask, there is no requirement on delivery of pending unblocked signals. This seems okay to me as an implementation might be able to satisfy an enquiry for the current mask without making a system call. After applying bug 1636, change:<blockquote>If there are any pending unblocked signals after the call to <i>pthread_sigmask</i>(), at least one of those signals shall be delivered before the call to <i>pthread_sigmask</i>() returns.</blockquote>to:<blockquote>If the argument <i>set</i> is not a null pointer, after <i>pthread_sigmask</i>() changes the currently blocked set of signals it shall determine whether there are any pending unblocked signals; if there are any, then at least one of those signals shall be delivered before the call to <i>pthread_sigmask</i>() returns.</blockquote> Issue History Date Modified Username Field Change ====================================================================== 2023-05-23 09:43 geoffclare New Issue 2023-05-23 09:43 geoffclare Name => Geoff Clare 2023-05-23 09:43 geoffclare Organization => The Open Group 2023-05-23 09:43 geoffclare Section => pthread_sigmask() 2023-05-23 09:43 geoffclare Page Number => 1734 2023-05-23 09:43 geoffclare Line Number => 56243 2023-05-23 09:43 geoffclare Interp Status => --- 2023-05-23 21:08 kre Note Added: 0006287 2023-05-25 08:40 geoffclare Note Added: 0006288 2023-05-25 18:26 kre Note Added: 0006292 2023-05-25 18:32 kre Note Edited: 0006292 2023-05-25 18:44 kre Note Added: 0006293 2023-05-30 11:14 geoffclare Note Added: 0006294 2023-05-31 19:50 kre Note Added: 0006296 2023-06-06 15:50 geoffclare Note Added: 0006312 2023-06-06 19:24 kre Note Added: 0006313 2023-06-07 09:44 geoffclare Note Added: 0006314 2023-06-09 11:24 kre Note Added: 0006316 2023-06-12 08:55 geoffclare Note Added: 0006319 ======================================================================
