From 60fce589e8c4b177ee5025269987476826ab6b0f Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Mon, 6 Dec 2004 22:29:01 +0000 Subject: [PATCH] * sysdeps/unix/clock_nanosleep.c (clock_nanosleep): Diagnose EINVAL for CLOCK_THREAD_CPUTIME_ID, not ENOTSUP. Use SYSDEP_NANOSLEEP handler before validating CLOCK_ID value. * rt/tst-timer4.c (TEST_CLOCK, TEST_CLOCK_NANOSLEEP): New macros. Use them throughout in place of CLOCK_REALTIME and nanosleep. (do_test) [TEST_CLOCK_MISSING]: Call this macro and if it returns non-null, punt the test with a message using the string returned. * rt/tst-timer5.c: New file. * rt/Makefile (tests): Add it. --- ChangeLog | 13 +++++++++++++ sysdeps/unix/clock_nanosleep.c | 13 ++++++++----- 2 files changed, 21 insertions(+), 5 deletions(-) diff --git a/ChangeLog b/ChangeLog index 9903bc9..1708f2d 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,16 @@ +2004-12-06 Roland McGrath + + * sysdeps/unix/clock_nanosleep.c (clock_nanosleep): Diagnose EINVAL + for CLOCK_THREAD_CPUTIME_ID, not ENOTSUP. + Use SYSDEP_NANOSLEEP handler before validating CLOCK_ID value. + + * rt/tst-timer4.c (TEST_CLOCK, TEST_CLOCK_NANOSLEEP): New macros. + Use them throughout in place of CLOCK_REALTIME and nanosleep. + (do_test) [TEST_CLOCK_MISSING]: Call this macro and if it returns + non-null, punt the test with a message using the string returned. + * rt/tst-timer5.c: New file. + * rt/Makefile (tests): Add it. + 2004-12-01 Paolo Bonzini * posix/regcomp.c (free_dfa_content, init_dfa): Remove diff --git a/sysdeps/unix/clock_nanosleep.c b/sysdeps/unix/clock_nanosleep.c index 6b170fd..248bfe1 100644 --- a/sysdeps/unix/clock_nanosleep.c +++ b/sysdeps/unix/clock_nanosleep.c @@ -1,5 +1,5 @@ /* High-resolution sleep with the specified clock. - Copyright (C) 2000, 2001, 2003 Free Software Foundation, Inc. + Copyright (C) 2000, 2001, 2003, 2004 Free Software Foundation, Inc.
