1997-10-31 23:16 Ulrich Drepper <drepper@cygnus.com> * posix/glob.c (glob): If calling glob_in_dir for a list which was generated by a glob call disable GLOB_ERR since there might be non-directories in the list (PR203). * posix/glob.h (GLOB_ONLYDIR): New flag. (__GLOB_FLAGS): Add GLOB_ONLYDIR. * posix/glob.c: Define HAVE_D_TYPE if _DIRENT_HAVE_D_TYPE is defined. (glob): Add GLOB_ONLYDIR to recursive call to match dirname. (glob_in_dir) [HAVE_D_TYPE]: While reading directory entries test whether they are directories if GLOB_ONLYDIR flag is given. * manual/pattern.texi: Document GLOB_ONLYDIR. * misc/Makefile (tests): Add tst-fdset. * sysdeps/i386/bits/select.h: Rewrite asm macros to be cleaner. * sysdeps/unix/sysv/linux/Dist: Add xstatconv.c. * sysdeps/unix/sysv/linux/alpha/Dist: Likewise. * time/strptime.c (strptime_internal): In %y format, regard years >= 69 as of twentieth century, all other as of twenty-first. * time/tzset.c: Correct typo and little optimization. 1997-10-31 16:01 Ulrich Drepper <drepper@cygnus.com> * inet/getnetgrent.c: Allocate buffer dynamically if needed. Suggested by Joe Keane <jgk@jgk.org>. 1997-10-31 Andreas Jaeger <aj@arthur.rhein-neckar.de> * io/ftw.h: Declare __ftw64_func_t and __nftw64_func_t only when __USE_FILE_OFFSET64 || __USE_LARGEFILE64 is true. 1997-10-30 05:47 Ulrich Drepper <drepper@cygnus.com> * misc/mntent.c: Don't use statically allocated buffer. Allocate it dynamically if necessary. * misc/efgcvt.c: Likewise. Patch by Joe Keane <jgk@jgk.org>. * misc/mntent.c: Allow freeing of allocated buffer in __libc_subfreeres. * misc/efgcvt.c: Likewise. * misc/efgcvt.c: Call correct reentrant functions. Use better values for MAXDIG. * misc/qefgcvt.c: Use better values for MAXDIG. 1997-10-29 18:48 Richard Henderson <rth@cygnus.com> * sysdeps/unix/sysv/linux/Makefile [io]: Add xstatconv. * sysdeps/unix/sysv/linux/alpha/xstatconv.c: New file. Convert between kernel_stat and the userland version indicated. * sysdeps/unix/sysv/linux/xstatconv.c: Likewise. * sysdeps/unix/sysv/linux/bits/stat.h: Define _STAT_VER_KERNEL. * sysdeps/unix/sysv/linux/fxstat.c: Defer to __xstat_conv. Alias to __*xstat64 if requested. * sysdeps/unix/sysv/linux/lxstat.c: Likewise. * sysdeps/unix/sysv/linux/xstat.c: Likewise. * sysdeps/unix/sysv/linux/alpha/bits/stat.h: Add struct stat64. Increment _STAT_VER, and make struct stat the same. * sysdeps/unix/sysv/linux/alpha/bits/types.h: Add __ino64_t, and __off64_t. Reorganize. * sysdeps/unix/sysv/linux/alpha/kernel_stat.h: Add struct glibc2_stat for backward compatibility. Define XSTAT_IS_XSTAT64. * sysdeps/unix/sysv/linux/alpha/fxstat64.c: Empty file. * sysdeps/unix/sysv/linux/alpha/lxstat64.c: Likewise. * sysdeps/unix/sysv/linux/alpha/xstat64.c: Likewise. * sysdeps/unix/sysv/linux/alpha/bits/dirent.h (struct dirent): For consistency, force d_ino to use ino_t and supply padding. 1997-10-29 18:47 Richard Henderson <rth@cygnus.com> * libio/iofopen.c: Correct weak_alias.
