From: Ulrich Drepper Date: Tue, 11 Apr 2000 16:27:38 +0000 (+0000) Subject: Update. X-Git-Tag: upstream/2.30~25875 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e7c036b39ef12abc7ff131982df75e3ec35c0f31;p=external%2Fglibc.git Update. 2000-04-11 Ulrich Drepper * posix/globtest.sh: Fix last change. 2000-04-10 Philip Blundell * sysdeps/unix/sysv/linux/bits/in.h (IPV6_JOIN_GROUP, IPV6_LEAVE_GROUP): New names for IPV6_ADD_MEMBERSHIP, IPV6_DROP_MEMBERSHIP. * sysdeps/generic/bits/in.h (IPV6_JOIN_GROUP, IPV6_LEAVE_GROUP): Likewise. 2000-04-11 Ulrich Drepper * elf/readlib (process_file): Close streams in case of an error. 2000-04-09 Andreas Jaeger * elf/readlib.c (process_file): Check if file is big enough to contain aout and ELF headers. Reported by Reinhard Moosauer . 2000-04-10 Jes Sorensen * elf/dl-fini.c: Include alloca.h to get proper prototype for alloca(). 2000-04-11 Ulrich Drepper * test-skeleton.c (main): If STDOUT_UNBUFFERED is defined, make stdout stream unbuffered. * rt/Makefile (tests): Add tst-clock. Add rules to build tst-clock. * rt/tst-clock.c: New file. * sysdeps/unix/i386/i586/clock_getres.c: Correct expression to decide about initialization of nsec. * sysdeps/unix/i386/i586/clock_gettime.c: Correct expression to decide about initialization of freq. Set retval to zero if successful. * sysdeps/unix/sysv/linux/i386/get_clockfreq.c: Cache result. --- diff --git a/ChangeLog b/ChangeLog index 33b152a..53bcae3 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,42 @@ +2000-04-11 Ulrich Drepper + + * posix/globtest.sh: Fix last change. + +2000-04-10 Philip Blundell + + * sysdeps/unix/sysv/linux/bits/in.h (IPV6_JOIN_GROUP, + IPV6_LEAVE_GROUP): New names for IPV6_ADD_MEMBERSHIP, + IPV6_DROP_MEMBERSHIP. + * sysdeps/generic/bits/in.h (IPV6_JOIN_GROUP, IPV6_LEAVE_GROUP): + Likewise. + +2000-04-11 Ulrich Drepper + + * elf/readlib (process_file): Close streams in case of an error. + +2000-04-09 Andreas Jaeger + + * elf/readlib.c (process_file): Check if file is big enough to + contain aout and ELF headers. + Reported by Reinhard Moosauer . + +2000-04-10 Jes Sorensen + + * elf/dl-fini.c: Include alloca.h to get proper prototype for alloca(). + +2000-04-11 Ulrich Drepper + + * test-skeleton.c (main): If STDOUT_UNBUFFERED is defined, make stdout + stream unbuffered. + * rt/Makefile (tests): Add tst-clock. + Add rules to build tst-clock. + * rt/tst-clock.c: New file. + * sysdeps/unix/i386/i586/clock_getres.c: Correct expression to decide + about initialization of nsec. + * sysdeps/unix/i386/i586/clock_gettime.c: Correct expression to decide + about initialization of freq.
