Thu Nov 14 02:00:33 1996 Ulrich Drepper <drepper@cygnus.com> * inet/Makefile (headers): Add aliases.h. (routines): Add getaliasent_r, getaliasent, getaliasname, and getaliasname_r. * aliases.h: New file. * inet/aliases.h: New file. * inet/getaliasent.c: New file. * inet/getaliasent_r.c: New file. * inet/getaliasname.c: New file. * inet/getaliasname_r.c: New file. * nss/Makefile (databases): Add alias. * nss/alias-lookup.c: New file. * nss/databases.def: Add aliases and publickey. * nss/nss_db/db-alias.c: New file. * nss/nss_files/files-alias.c: New file. * inet/getnetgrent_r.c (__internal_getnetgrent): Buffer length argument to lookup function is of type size_t. (innetgr): Likewise. * nss/getXXbyYY_r.c: Likewise. * nss/getXXent_r.c: Likewise. * nss/nss_db/db-XXX.c: Likewise. * nss/getXXbyYY.c: Don't provide static buffer. Resize if call failed because buffer was too small. * nss/getXXent.c: Likewise. * nss/nss_files/files-XXX.c: Correct handling of shared file. The getXXent_r function now uses f[gs]etpos to get to the correct position. * nss/nss_files/files-parse.c: Indent lines for better readability. * malloc/obstack.c: Add new variable obstack_alloc_failed_handler and new function print_and_abort. Remove all references to alloc_failed field. Add new function _obstack_memory_used. * malloc/obstack.h (struct obstack): Remove field alloc_field. Remove all references to alloc_failed field. Add prototype for _obstack_memory_used. * posix/unistd.h: Correct typo. Wed Nov 13 03:09:16 1996 Ulrich Drepper <drepper@cygnus.com> * configure.in: Require at least autoconf-2.10.2. Tue Nov 12 03:35:01 1996 Christian von Roques <roques@pond.sub.org> * malloc/obstack.h: Add new macro `obstack_make_room'. * malloc/obstack.c: Add function implementation for `obstack_make_room'. Mon Nov 11 13:54:04 1996 Ulrich Drepper <drepper@cygnus.com> Update to BIND-4.9.5-REL. * resolv/Banner: Set to 4.9.5-REL. * resolv/inet_net_pton.c: Was doing bad things to subnets and b'casts. * resolv/res_debug.c (__fp_nquery): Could read past end of buffer. (fix from BIND 8.1) * config.make.in: Add definition for top_absdir. * Makerules (make-link): Fix path to rellns-sh script. Sat Nov 9 02:15:24 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * posix/unistd.h: Fix comment. * manual/arith.texi: Fix misspellings. Use `zero', not `null', when talking about numbers. * manual/users.texi: Likewise. * manual/creature.texi: Likewise. Use @defvarx for a secondary description header. Sat Nov 9 19:25:11 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * sysdeps/posix/Makefile ($(common-objpfx)mk-stdiolim): Depend on the real posix1_lim.h file so that it works in all subdirs, not only in posix. Sat Nov 9 02:08:34 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * Makefile ($(includedir)/gnu/lib-names.h): Quote arguments of tr. Sat Nov 9 02:06:17 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * sysdeps/unix/Makefile ($(common-objpfx)s-proto.d): Don't depend on $(before-compile) which hasn't been properly setup yet at this point. Sat Nov 9 02:02:48 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * sysdeps/generic/sigset.h: Don't use implicit int which will probably require a diagnostic in the next revision of the C standard. * sysdeps/stub/lockfile.c: Likewise. Sat Nov 9 01:57:17 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * sysdeps/unix/sysv/linux/m68k/syscall.S: Correct last change. * sysdeps/unix/sysv/linux/m68k/sysdep.h: Likewise. Mon Nov 11 02:53:14 1996 Ulrich Drepper <drepper@cygnus.com> * time/strftime.c: Update copyright. Small cosmetic changes. char *' and `int'. PROJ_ID are used.
