1998-03-13 16:55 Ulrich Drepper <drepper@cygnus.com>
* string/tester.c (test_strpbrk): Add more strpbrk tests.
(test_strsep): Likewise. Correct horrible bugs.
* string/bits/string2.h (strcspn): Optimize also reject string of
length 2 and 3.
(strspn): Likewise.
(strpbrk): Likewise.
(strsep): Likewise. Correct bug with successive separators and
separators at the end of the string.
* sysdeps/generic/strsep.c: Correct bug with successive separators
and separators at the end of the string.
1998-03-13 13:11 Tim Waugh <tim@cyberelk.demon.co.uk>
* posix/wordexp.c (parse_param): Positional parameters ($1, $2
etc) now handled, as well as $$ (pid).
* posix/Makefile (tests): Execute wordexp-test.sh for `make check'.
(distribute): Add wordexp-tst.sh.
* posix/wordexp-tst.sh: New file.
* posix/wordexp.c (parse_param): $# (or ${#}) expands to the
number of positional parameters. Renamed substitute_length to
seen_hash.
Don't free(env) is env is NULL.
1998-03-13 16:50 Ulrich Drepper <drepper@cygnus.com>
* libc.map: Add pthread_attr_init to GLIBC_2.1.
1998-03-13 15:01 Ulrich Drepper <drepper@cygnus.com>
* gmon/gmon.c: Allow GMON_OUT_PREFIX variable to specify filename
for output file replacing gmon.out.
Patch by Dean Gaudet <dgaudet@arctic.org>.
1998-03-12 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
* elf/dl-misc.c (_dl_debug_message): Fix printing of pid. Clean
up namespace. Optimize finding end of line.
1998-03-12 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
* elf/rtld.c (process_envvars): Ignore LD_DEBUG_OUTPUT if running
securely. Optimized.
(process_dl_debug): Add ':' to list of separators. Optimized.
