+2003-10-16 Paul Eggert <eggert@twinsun.com>
+
+ * getgroups.c: Include <errno.h>, <stdlib.h>.
+ (getgroups): First arg is int, not size_t.
+ Don't let 'free' mangle errno.
+
+2003-10-16 Jim Meyering <jim@meyering.net>
+
+ * xmalloc.c: Include <string.h>, for declarations of memset and memcpy.
+
+2003-10-15 Paul Eggert <eggert@twinsun.com>
+
+ * exclude.c: Do not include <inttypes.h> or <stdint.h>.
+ (SIZE_MAX): Remove.
+ (new_exclude, add_exclude_file): Initial size no longer needs to
+ be a power of 2.
+ (add_exclude, add_exclude_file): Use xnrealloc instead of rolling
+ our own address arithmetic overflow checking.
+
+ * fnmatch.c (SIZE_MAX): Define if standard headers don't.
+ (fnmatch): Do not alloca more than 2000 wide characters;
+ instead, use malloc for large buffers.
+ Check for address arithmetic overflow, and return -1
+ with errno set to ENOMEM in that case.
+ * fnmatch_loop.c (ALLOCA_LIMIT): New macro.
+ (NEW_PATTERN): Do not alloca more than 8000 bytes;
+ instead, return -1. Check for address arithmetic overflow.
+
+2003-10-14 Paul Eggert <eggert@twinsun.com>
+
+ Handle invalid suffixes and overflow independently, so that
+ callers can treat them independently as needed. Fix some bugs in
+ suffix handling, e.g., "100k@" was not diagnosed as an invalid
+ suffix for a human-readable blocksize. The major caller-visible
+ change is the addition of a new
+ LONGINT_INVALID_SUFFIX_CHAR_WITH_OVERFLOW enum value, indicating
+ that both overflow and suffix chars were found.
+
+ * human.c (humblock): Don't check separately for invalid suffix
+ char; that is xstrtoumax's job (now that its bug is fixed).
+ * xstrtoimax.c (STRTOL_T_MINIMUM, STRTOL_T_MAXIMUM) [defined
+ INTMAX_MAX]: New macros.
+ * xstrtol.c (STRTOL_T_MINIMUM, STRTOL_T_MAXIMUM, TYPE_MINIMUM,
+ TYPE_MAXIMUM): New macros.
+ (bkm_scale, bkm_scale_by_power): Return strtol_error, not int.
+ (bkm_scale, bkm_scale_by_power, __xstrtol): Return maximal values
+ if overflow occurs, as it's what __strtol does and it's more useful
+ in practice.
+ (__xstrtol): If __strtol reports some error other than ERANGE,
+ reflect it to the caller as LONGINT_INVALID. If it reports
+ ERANGE, continue the rest of parsing, and report LONGINT_OVERFLOW
+ | LONGINT_INVALID_SUFFIX_CHAR if both errors occur.
+ * xstrtol.h (LONGINT_INVALID_SUFFIX_CHAR_WITH_OVERFLOW): New enum
+ value.
+ (_STRTOL_ERROR): Handle it. Abort when given unknown error codes.
+ * xstrtoul.c (STRTOL_T_MINIMUM, STRTOL_T_MAXIMUM): New macros.
+ * xstrtoumax.c (STRTOL_T_MINIMUM, STRTOL_T_MAXIMUM)
+ [defined UINTMAX_MAX]: New macros.
+
+2003-10-14 Bruno Haible <bruno@clisp.org>
+
+ * fatal-signal.h: Improved comments. Suggested by Paul Eggert.
+ * fatal-signal.c: Use sig_atomic_t. Suggested by Paul Eggert.
+ Also use volatile where needed.
+
+2003-10-12 Paul Eggert <eggert@twinsun.com>
+
+ * lib/xalloc.h (xnmalloc, xzalloc, xnrealloc, xclone): New decls.
+ (XMALLOC, XCALLOC, XREALLOC, XFREE, CCLONE, CLONE): Deprecate,
+ and define in terms of the other primitives.
+ * lib/xmalloc.c: Include stdbool.h; do not include exit.h.
+ (SIZE_MAX): Define if not already defined.
+ (array_size_overflow): New function.
+ (xalloc_die): Abort instead of exiting if 'error' returns.
+ (xnmalloc, xnrealloc, xzalloc, xclone): New functions.
+ (xmalloc, xrealloc): Use them.
+ (xcalloc): Check for address arithmetic overflow.
+ * lib/xstrdup.c (xstrdup): Use xclone, since memcpy should be
+ a bit faster than strcpy.
+
+2003-10-08 Paul Eggert <eggert@twinsun.com>
+
+ Merge getpass from libc, plus a few fixes.
+
+ * getpass.c (HAVE_STDIO_EXT) [_LIBC]: Define to 1.
+ Include <stdbool.h>.
+ Include <stdio_ext.h> if HAVE_STDIO_H, otherwise define
+ __fsetlocking to empty.
+ [_LIBC]: Do not include "getline.h" or "unlocked-io.h", but
+ do include <bits/libc-lock.h>.
+ Do not include <fcntl.h>; not needed.
+ [_LIBC]: Include <wchar.h>.
+ (NOTCANCEL_MODE): New macro.
+ (flockfile, funlockfile) [_LIBC]: New macros.
+ (__libc_cleanup_push, __libc_cleanup_pop, __getline, __tcgetattr)
+ [!_LIBC]: New macros.
+ (call_fclose): New function.
+ (getpass): Use it. Save tty stream separately; this simplifies the
+ code and makes it more reliable if stdin happens to equal stdout.
+ Invoke __fsetlocking on tty.
+ Handle thread cancellation if needed.
+ Namespace cleanup (use __tcgetattr, __getline).
+ Use bool for Booleans.
+ [USE_IN_LIBIO]: Handle wide streams.
+ [!_LIBC]: Unconditionally do the fseek, since we don't know what
+ stream might go where.
+
+ * unlocked-io.h: Include <stdio.h>, so that the caller
+ doesn't have to include <stdio.h> before us.
+ (clearerr_unlocked, feof_unlocked, ferror_unlocked,
+ fflush_unlocked, fgets_unlocked, fputc_unlocked, fputs_unlocked,
+ fread_unlocked, fwrite_unlocked, getc_unlocked, getchar_unlocked,
+ putc_unlocked, putchar_unlocked): Define to the unlocked counterpart
+ if not declared, so that we can use getpass.c code from libc without
+ rewriting it.
+ (flockfile, ftrylockfile, funlockfile): New macros.
+
+2003-10-06 Bruno Haible <bruno@clisp.org>
+
+ * version-etc-2.h: Remove file.
+ * version-etc-2.c: Remove file.
+
+2003-09-25 Jim Meyering <jim@meyering.net>
+ Bruno Haible <bruno@clisp.org>
+
+ This lets translators provide better translations for the
+ "Written by ..." part of --version output.
+ * version-etc.h: Include stdarg.h.
+ (version_etc_copyright): Declare as readonly.
+ (version_etc): Make this function variadic with a NULL-terminated list
+ of author name strings.
+ (version_etc_va): New declaration.
+ * version-etc.c: Include stdarg.h, stdlib.h.
+ (version_etc_copyright): Declare as readonly.
+ (version_etc_va): New function. Provide a different translatable string
+ for each possible number of authors < 10. Abbreviate when there are 10
+ authors or more.
+ (version_etc): Make this function variadic. Call version_etc_va.
+ Suggestion from Gary V. Vaughan.
+
+ * long-options.h (parse_long_options): Change prototype: the authors
+ string is moved to the end and becomes variadic.
+ * long-options.c: Include stdarg.h.
+ (parse_long_options): Make this function variadic, too.
+ Call version_etc_va, not version_etc.
+
+2003-10-06 Bruno Haible <bruno@clisp.org>
+
+ * fatal-signal.h: New file, from GNU gettext.
+ * fatal-signal.c: New file, from GNU gettext.

+
+ * argp*: update from libc.
+
+2003-10-01 Larry Jones <lawrence.jones@eds.com>
+
+ * getpass.c (getpass): Use a no-op fseek when switching from input to
+ output mode on the same stream.
+
+2003-09-29 Paul Eggert <eggert@twinsun.com>
+
+ * strftime.c (tm_diff) [! HAVE_TM_GMTOFF]:
+ Fix arg typo in previous patch.
+
+2003-09-28 Jim Meyering <jim@meyering.net>
+
+ * error.c: Correct cpp indentation.
+
+2003-09-27 Paul Eggert <eggert@twinsun.com>
+
+ * minmax.h (MIN, MAX) [__STDC__ && defined __GNUC__ && __GNUC__ >= 2]:
+ Omit the special code that used __typeof__, since we worry that
+ it could be more trouble than it's worth. See:
+ http://mail.gnu.org/archive/html/bug-gnulib/2003-01/msg00090.html
+ http://mail.gnu.org/archive/html/bug-gnulib/2003-01/msg00095.html

+ into inner scope where the local variables are used.
+
+2003-09-26 Bruno Haible <bruno@clisp.org>
+
+ * stpncpy.h (gnu_stpncpy): New declaration.
+ (stpncpy): Define as alias for gnu_stpncpy.
+ * stpncpy.c [!_LIBC]: Define gnu_stpncpy, not stpncpy.
+
+2003-09-26 Paul Eggert <eggert@twinsun.com>
+
+ * error.c (SIZE_MAX) [!defined SIZE_MAX]: Define.
+ (error_tail): Do not loop, reallocating temporary buffer, since
+ the output cannot contain more wide characters than the input
+ contains bytes, the size must be big enough already. This avoids
+ one potential size overflow calculation. Check for size overflow
+ when calculating temporary buffer size. Free temporary buffer
+ when done, if it was allocated with malloc; this plugs a memory
+ leak. Remove casts from void * to pointers, that are no longer
+ needed now that we're assuming C89 or better.
+
+ Merge error changes from glibc.
+
+ * error.c, error.h: Update copyright notice header to match glibc.
+ * error.c [defined _LIBC]: Include <errno.h>, <bits/libc-lock.h>.
+ (error, error_at_line) [defined _LIBC && defined __libc_ptf_call]:
+ Disable cancellation while printing error.
+ * error.h: Prepend __ to parameter names.

+
+2003-09-24 Paul Eggert <eggert@twinsun.com>
+

+ the buffer associated with the argument. Bug reported by
+ Simon Josefsson.
+
+2003-09-19 Karl Berry <karl@gnu.org>
+
+ * argp.h: update from libc.
+
+2003-09-16 Paul Eggert <eggert@twinsun.com>
+
+ * linebuffer.c (readlinebuffer): Return NULL immediately upon
+ input error, instead of returning NULL the next time we are called
+ (and therefore losing track of errno).
+
+2003-09-15 Paul Eggert <eggert@twinsun.com>
+
+ * getndelim2.c (getndelim2): Don't trash errno when a read
+ fails, so that the caller gets the proper errno.
+
+ * readutmp.c (read_utmp): Likewise.
+ Check for fstat error. Close stream and free storage
+ when failing.
+
