From a86c329f99bf9cccb98a80f6d01316fb5305a169 Mon Sep 17 00:00:00 2001 From: Bruce Momjian Date: Mon, 5 Apr 2004 14:12:32 +0000 Subject: [PATCH] Change getpid() while loop to use sched_yield(), greatly speeds up test. sched_yield is a requirement for the test but not for our PostgreSQL code, so if it causes a portability problem, we will remove it. --- src/tools/thread/thread_test.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) diff --git a/src/tools/thread/thread_test.c b/src/tools/thread/thread_test.c index d7ea309d24..903462755f 100644 --- a/src/tools/thread/thread_test.c +++ b/src/tools/thread/thread_test.c @@ -6,7 +6,7 @@ * Portions Copyright (c) 1996-2003, PostgreSQL Global Development Group * Portions Copyright (c) 1994, Regents of the University of California * - * $PostgreSQL: pgsql/src/tools/thread/thread_test.c,v 1.13 2004/04/05 05:43:06 momjian Exp $ + * $PostgreSQL: pgsql/src/tools/thread/thread_test.c,v 1.14 2004/04/05 14:12:32 momjian Exp $ * * This program tests to see if your standard libc functions use * pthread_setspecific()/pthread_getspecific() to be thread-safe. @@ -83,7 +83,7 @@ defines to your template/$port file before compiling this program.\n\n" pthread_create(&thread2, NULL, (void * (*)(void *)) func_call_2, NULL); while (thread1_done == 0 || thread2_done == 0) - getpid(); /* force system call */ + sched_yield(); /* force system call */ printf("Add this to your template/$port file:\n\n"); @@ -129,7 +129,7 @@ void func_call_1(void) { */ errno1_set = 1; while (errno2_set == 0) - getpid(); /* force system call */ + sched_yield(); /* force system call */ if (errno != EEXIST) { fprintf(stderr, "errno not thread-safe; exiting\n"); @@ -184,7 +184,7 @@ void func_call_2(void) { */ errno2_set = 1; while (errno1_set == 0) - getpid(); /* force system call */ + sched_yield(); /* force system call */ if (errno != ENOENT) { fprintf(stderr, "errno not thread-safe; exiting\n"); -- 2.40.0
