Mon Oct 21 01:32:36 1996 Ulrich Drepper <drepper@cygnus.com> * elf/rtld.c (dl_main): Move initialization of `_dl_starting_up' to beginning of function. So libc functions can use this flag. * sysdeps/generic/_strerror.c: Don't use dgettext for message translation while `_dl_starting_up' is nonzero. * elf/dl-deps.c (_dl_map_object_deps): Add new parameter TRACE_MODE. Pass parameter value to _dl_map_object. * elf/dl-load (_dl_map_object): Add new parameter TRACE_MODE. If TRACE_MODE is nonzero don#t signal error when shared lib is not found. Instead create fake entry for link map. * dl-open.c (dl-open): Pass 0 for new argument to _dl_map_object. * dl-runtime.c (_dl_object_relocation_scope): Pass 0 for new argument to _dl_map_object_deps. * elf/link.h: Add new parameter TRACE_MODE for prototypes of _dl_map_object and _dl_map_object_deps. * elf/rtld.c (dl_main): Pass 0 for new argument to _dl_map_object and _dl_map_object_deps. When mode == trace test for l_opencount == 0 before printing link information since this means the lib is not found. Sun Oct 20 22:19:58 1996 Ulrich Drepper <drepper@cygnus.com> * rpm/template: Add INSTALL to %doc line to follow copyright restrictions which demand the distribution of the copyright messages in INSTALL even for binary distributions. * features.h: Rename to... * features.h.in: ...this. Change value of __GNU_LIBRARY__ to 2 (for major version numberof package) and add __GNU_LIBRARY_MINOR__ and __GNU_LIBRARY_INTERFACE__. * Makefile ($(objpfx)features.h): New rule to generate features.h from template features.h.in. * sysdeps/unix/sysv/linux/getsysstats.c: Include <paths.h>. Sun Oct 20 00:00:13 1996 Richard Henderson <rth@tamu.edu> * locale/programs/linereader.c (lr_open): Cast away const before free. (lr_close): Likewise. * misc/mntent.h: Move _PATH_MNTTAB & _PATH_MOUNTED to paths.h. * misc/paths.h: Move to ... * sysdeps/generic/paths.h: ... here. * paths.h: Remove. * sysdeps/unix/sysv/linux/paths.h: New file. Correct _PATH_STDPATH, _PATH_MAILDIR, _PATH_MOUNTED, _PATH_UNIX to comply with the fsstd. * nss/nss_db/db-netgrp.h: Include <string.h>. * stdio-common/psignal.c: De-ansidecl-ify. Allow NULL entries in _sys_siglist, which result in the "Unknown signal" message. * string/strsignal.c: Likewise. * sysdeps/generic/Makefile [stdio-common]: If $(inhibit-siglist), don't auto-generate siglist.c. * sysdeps/unix/sysv/linux/Makefile [stdio-common]: Set inhibit-siglist. * sysdeps/unix/sysv/linux/siglist.c: New file. Not needing to autogenerate makes bootstrapping and cross-compiling much easier. * sysdeps/unix/sysv/linux/siglist.h: New file. * stdlib/longlong.h: Prototype __udiv_qrnnd. * sysdeps/unix/sysv/linux/alpha/Makefile (sysdep_headers): Remove sys/io.h. It is already added in .../linux/Makefile. * sysdeps/unix/sysv/linux/alpha/sigaction.h: New file. * sysdeps/unix/sysv/linux/alpha/signum.h: New file. * sysdeps/unix/sysv/linux/alpha/statbuf.h: New file. Sun Oct 20 17:17:12 1996 Ulrich Drepper <drepper@cygnus.com> Add implementation of POSIX.1g function getaddrinfo. * posix/Makefile (routines): Add getaddrinfo. * sysdeps/posix/getaddrinfo.c.: New file. Add implementation by Craig Metz. * sysdeps/stub/getaddrinfo.c: New file. Stub implementation. * resolv/netdb.h [__USE_POSIX]: Add getaddrinfo prototypes and related constants and structures. Sun Oct 20 13:02:34 1996 Ulrich Drepper <drepper@cygnus.com> * sysdeps/stub/lockfile.c: Rename functions to __internal_*. Make all old names weak alises so that they can be replaced by libpthread. * stdio-common/vfprintf.c: Only declare __flockfile and __funlockfile for !USE_IN_LIBIO. [USE_IN_LIBIO]: Call _IO_flockfile and _IO_funlockfile instead of __flockfile and __funlockfile. Reported by NIIBE Yutaka. * crypt/md5.c: Change form of copyright message according to GNITS rules. Add warning for requirement on RESBUF parameter for `md5_finish_ctx' and `md5_read_ctx' function. * crypt/md5.h: Likewise. * grp/testgrp.c: Don't use perror for error cases since getgr* and getpw* functions do not return usable error codes. Sun Oct 19 23:05:32 1996 Jim Meyering <meyering@asic.sc.ti.com> * crypt/md5.c (md5_process_bytes): Used casting for pointer arithmetic. Sun Oct 20 03:53:23 1996 Ulrich Drepper <drepper@cygnus.com> * sunrpc/Makefile (others): Remove portmap here, too.
