Thu Jun 6 07:32:14 1996 Miles Bader <miles@gnu.ai.mit.edu> * resolv/gethnamaddr.c (struct hstorage): Make NAME field a pointer. (_gethtbyname2): Remove ALIAS variable. Initialize NAME field of SELF and TARGET to 0. Add SELF_NAME_SIZE static variable. Add loop to call gethostname until the space we allocated is enough. Use malloced strings instead of fixed size buffers. <stdlib.h>, <unistd.h>: New includes. * sysdeps/generic/sys/socket.h (PF_INET6, AF_INET6): New macros. * sysdeps/mach/hurd/errlist.c (_sys_errlist): Add EILSEQ. (_sys_nerr): Initialize to 107. Update _HURD_ERRNOS consistency check. * stdlib/canonicalize.c (canonicalize): Use pathconf for PATH_MAX, not sysconf. * login/login.c [!PATH_MAX] (PATH_MAX): Define to be 1024 if not already defined. * sysdeps/mach/hurd/setitimer.c (timer_thread): Supply SIGCODE argument to __msg_sig_post_request. * hurd/hurdmalloc.c: Changes to bring in line with the hurd libthreads/malloc.c: (more_memory): Use assert_perror instead of MACH_CALL. "cthread_internals.h": Include removed. (realloc): Use LOG2_MIN_SIZE. (LOG2_MIN_SIZE): New macro. (realloc): Don't bother allocating a new block if the new size request fits in the old one and doesn't waste any space. Only free the old block if we successfully got a new one. [MCHECK] (struct header): New type. (union header): Only define if !MCHECK. (HEADER_SIZE, HEADER_NEXT, HEADER_FREE, HEADER_CHECK): New macros. [MCHECK] (MIN_SIZE): Add correct definition for this case. (more_memory, malloc, free, realloc): Use above macros, and add appropiate checks & frobs in MCHECK case.
