Tue Jun 25 02:59:11 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu>cvs/libc-960625
* malloc/malloc.h: Declare malloc_object_allocated_size, malloc_walk. * malloc/Makefile (dist-routines): Add malloc-size, malloc-walk. * malloc/malloc-size.c: New file. * malloc/malloc-walk.c: New file. * malloc/malloc-find.c (malloc_find_object_address): Return null if PTR is outside the heap. * elf/dl-load.c (_dl_map_object): If the requested name matches the soname of a loaded object, use that object. Mon Jun 24 19:57:01 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu> * Makefile (subdirs): Add nss. * inet/Makefile (routines): Add getrpcent, getrpcbyname, getrpcbynumber, getrpcent_r, getrpcbyname_r, getrpcbynumber_r. * inet/getrpcbynumber_r.c: New file. * inet/getrpcbynumber.c: New file. * inet/getrpcbyname.c: New file. * inet/getrpcbyname_r.c: New file. * inet/getrpcent_r.c: New file. * inet/getrpcent.c: New file. * nss/rpc-lookup.c: New file. * nss/nss_files/files-rpc.c: New file. * nss/Makefile (routines): Add rpc-lookup. (libnss_files-routines): Add files-rpc. * sunrpc/Makefile (routines): Remove getrpcent. * sunrpc/getrpcent.c: File removed. * nss/getXXent_r.c (REENTRANT_GETNAME): Clear NO_MORE when NIP is non-null on entry. * Makeconfig (rpath-link): Add $(nssobjdir). (nssobjdir): New variable. * Makerules: Move shared library building before objects rules, so versions are known before extra-lib.mk gets included. * extra-lib.mk (lib-noranlib): Depend on the shared object too. * pwd/getpwuid.c: Rewritten using nss. * pwd/getpwnam.c: Likewise. * pwd/getpwent.c: Likewise. * grp/getgrnam.c: Likewise. * grp/getgrgid.c: Likewise. * grp/getgrent.c: Likewise. * pwd/Makefile (routines): Add getpwent_r, getpwnam_r, getpwuid_r. * pwd/getpwent_r.c: New file. * pwd/getpwnam_r.c: New file. * pwd/getpwuid_r.c: New file. * grp/Makefile (routines): Add getgrent_r, getgrgid_r, getgrnam_r. * grp/getgrnam_r.c: New file. * grp/getgrgid_r.c: New file. * grp/getgrent_r.c: New file. * grp/Makefile (routines): Remove grpopen, grpread. * pwd/Makefile (routines): Remove pwdopen, pwdread. * grp/grpopen.c, grp/grpread.c, pwd/pwdopen.c, pwd/pwdread.c: Removed. * pwd/fgetpwent.c: Rewritten using files-parse.c. * grp/fgetgrent.c: Likewise. * nss/Makefile (routines): Add grp-lookup and pwd-lookup. * nss/pwd-lookup.c, nss/grp-lookup.c: New files. * nss/nss_files/files-grp.c: New file. * nss/nss_files/files-pwd.c: New file. * nss/Makefile (subdir-dirs): New variable; use it in vpath. * nss/nss_files/files-parse.c: New file. * nss/nss_files/files-XXX.c: New file. * nss/nss_files/files-hosts.c, nss/nss_files/files-proto.c, nss/nss_files/files-service.c, nss/nss_files/files-network.c: Rewritten using them. * nss/Makefile (libnss_files-routines): Remove files-host. Add files-hosts, files-grp, files-pwd. * nss/nss_dns/dns-network.c: Don't include <pthread.h>. Mon Jun 24 22:39:12 1996 Richard Henderson <rth@tamu.edu> * sysdeps/alpha/dl-machine.h (ELF_MACHINE_RUNTIME_TRAMPOLINE): A .plt entry now loads the .rela.plt offset directly rather than making us calculate it. Sun Jun 23 15:24:05 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu> * time/Makefile ($(installed-localtime-file) rule): Do $(make-target-directory) first. * resolv.h: Fix wrapper for resolv/resolv.h. * configure.in (ld --no-whole-archive check): Use AC_TRY_COMMAND. Compile dummy file and pass -nostdlib -nostartfiles so as not to require installed libraries. * shlib-versions (*-*-*): Set libresolv=2, libnss_files=1, libnss_dns=1. Sun Jun 23 19:42:05 1996 Ulrich Drepper <drepper@cygnus.com> * resolv/netdb.h (_PATH_NSSWITCH_CONF): New macro. * inet/herrno.c: New file. * resolv/res_init.c: Remove res_hconf calls. * nss/Makefile, nss/XXX-lookup.c, nss/file-lookup.c, nss/getXXbyYY.c, nss/getXXbyYY_r.c, nss/getXXent.c, nss/getXXent_r.c, nss/host-lookup.c, nss/network-lookup.c, nss/nsswitch.c, nss/nsswitch.h, nss/proto-lookup.c, nss/service-lookup.c: New files. Implementation of name service switch, following the approach in Solaris. Interface specification and general structure inspired by Peter Eriksson <pen@lysator.liu.se>. * nss/nss_files/files-host.c, nss/nss_files/files-network.c, nss/nss_files/files-proto.c, nss/nss_files/files-service.c: Implementation of libnss_files.so module for file based databases in NSS service. * nss/nss_dns/dns-host.c, nss/nss_dns/dns-network.c: Implementation if libnss_dns.so module for DNS name lookup in NSS service. * inet/getproto.c, inet/getprtent.c, inet/getprtname.c, inet/getservent.c, inet/getsrvbynm.c, inet/getsrvbypt.c: Changed to serve as interface to NSS. * inet/gethstbyad.c, inet/gethstbyad_r.c, inet/gethstbynm.c, inet/gethstbynm2.c, inet/gethstbynm2_r.c, inet/gethstbynm_r.c, inet/gethstent.c, inet/gethstent_r.c, inet/getnetbynm.c, inet/getnetbynm_r.c, inet/getnetbypt.c, inet/getnetbypt_r.c, inet/getnetent.c, inet/getnetent_r.c, inet/getproto_r.c, inet/getprtent_r.c, inet/getprtname_r.c, inet/getservent_r.c, inet/getsrvbynm_r.c, inet/getsrvbypt_r.c: New files. Implement interfaces to NSS, including reentrant functions. * resolv/getnetbyaddr.c, resolv/getnetbyname.c, resolv/getnetent.c, resolv/sethostent.c: Removed: Obsoleted by NSS. * resolv/mapv4v6addr.h, resolv/mapv4v6hostent.h: Extracted from gethnamaddr.c. These private functions are now used in more than one file. * resolv/inet_pton.c, resolv/gethnamaddr.c: Updated to bind-4.9.4-T5B. Sat Jun 22 16:49:47 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * rpm/Makefile ($(config)): Make sure the word list in the for loop is syntactically non-empty.
