Sun Jul 14 01:51:39 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu>cvs/libc-960714
* manual/Makefile (glibc-targets): Variable and targets removed. Sat Jul 13 23:50:17 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu> * manual/Makefile (lib): New phony target. Depend on stamp files. ($(objpfx)stamp%-$(subdir)): New rule to create them when necessary. 1996-07-13 Paul Eggert <eggert@twinsun.com> * time/strftime.c (strftime): Use space padding for %e, %k, %l, to match Emacs format-time-string specification. (DO_NUMBER_SPACEPAD): Renamed from DO_NUMBER_NOPAD. Sat Jul 13 20:17:38 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu> * elf/dl-deps.c (_dl_map_object_deps): Take new args PRELOADS and NPRELOADS, vector of `struct link_map *'s; add them to the searchlist between MAP and its deps. * elf/link.h: Fix decl. * elf/rtld.c (dl_main): If not secure, parse LD_PRELOAD for colon-separated list of names, map those and pass vector of ptrs as PRELOADS list to _dl_map_object_deps. * elf/dl-runtime.c (_dl_object_relocation_scope): Pass new args to _dl_map_object_deps with empty preload list. * elf/dl-open.c (_dl_open): Likewise. * sysdeps/mach/hurd/dl-sysdep.c (_dl_sysdep_open_zero_fill): Function removed. (__mmap): Pass MACH_PORT_NULL for memobj port when (flags & MAP_ANON). * sysdeps/generic/dl-sysdep.c (_dl_sysdep_open_zero_fill): Conditionalize defn on [! MAP_ANON]. * elf/dl-minimal.c (malloc): Conditionalize use of _dl_zerofd on [! MAP_ANON]. * elf/rtld.c (dl_main): Likewise. * elf/dl-load.c (_dl_zerofd): Conditionalize defn on [! MAP_ANON]. (_dl_map_object_from_fd): Conditionalize initialization of _dl_zerofd. * elf/dl-fini.c (_dl_fini): Skip finalizer for executable itself. Sat Jul 13 02:47:53 1996 David Mosberger-Tang <davidm@azstarnet.com> * stdlib/random.c (__random): Declare as int32_t to be in sync with declaration. * socket/Makefile (headers): Add socketbits.h. * misc/mntent.c (endmntent): Allow for NULL stream. SunOS does it that way. * grp/initgroups.c (initgroups): Add groups that user is a member of, not the ones he is _not_ a member of. * nss/nsswitch.c (known_compare): Make known_compare() a static instead of a local function. The latter are difficult to debug and slow to execute on certain platforms. * sysdeps/posix/ttyname_r.c (ttyname_r): Use sizeof (dev) - 1 in place of sizeof (dev). The size of a literal string includes the NUL byte. * sysdeps/unix/getlogin.c (getlogin): Initialize ut_fd with -1. Thu Jul 11 16:59:10 1996 David Mosberger-Tang <davidm@azstarnet.com> * misc/mntent.c (addmntent): Seek to end of file before writing entry. Return 1 on error, not -1. Tue Jul 9 19:08:05 1996 David Mosberger-Tang <davidm@azstarnet.com> * sysdeps/unix/sysv/linux/syscalls.list: Mark bdflush as EXTRA syscall. Fri Jul 5 18:44:55 1996 David Mosberger-Tang <davidm@azstarnet.com> * sysdeps/unix/sysv/linux/alpha/ioperm.c (port_to_cpu_addr): Size shift amount for Jensen must be 5 not 4. Sat Jul 13 20:04:28 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu> * socket/sys/socket.h (struct osockaddr): New type. Sat Jul 13 03:50:53 1996 Ulrich Drepper <drepper@cygnus.com> * misc/Makefile (routines): Add qefgcvt and qefgcvt_r. * misc/efgcvt.c, misc/efgcvt_r.c: Change code so that the `double' and `long double' versions can be generated. * misc/qefgcvt.c, misc/qefgcvt_r.c: New files. Define macros so that included efgcvt{,_r}.c file generate `long double' versions. * stdlib/stdlib.h: Add prototypes for q[efg]cvt() and q[ef]cvt_r() functions. * manual/startup.texi: Document new getsubopt function. * manual/examples/subopt.c: New example program for documenting getsubopt function. Fri Jul 12 23:58:37 1996 Ulrich Drepper <drepper@cygnus.com> * stdlib/Makefile (routines): Add getsubopt. * stdlib/stdlib.h: Add prototype for getsubopt. * stdlib/getsubopt.c: New file. Implement getsubopt function to handle suboption parsing.
