+
+ On 64-bit hosts (where size_t is 64 bits and int is 32 bits), the
+ old glibc regex code mishandles strings longer than 2**31 bytes.
+ This patch fixes this when the regex code is used in gnulib
+ (i.e., outside glibc).
+
+ This patch should not affect the use of the regex code inside
+ glibc. No doubt this problem also needs to be handled for glibc
+ as well, but the result will be an incompatible change to the
+ glibc ABI, and the old ABI will have to be supported too. That
+ can be the the subject for another patch.
+
+ * regex.h (_REGEX_LARGE_OFFSETS): New feature-test macro,
+ governing whether the rest of this patch is active. By default,
+ the macro is disabled and the patch has no effect.

+ * strftime.c (my_strftime) [! defined _LIBC && ! HAVE_RUN_TZSET_TEST]:
+ Copy the input structure, to work around some of the bug with

+ (ranged_convert, __mktime_internal): When calling a function via a

+ White space changes only.
+ * makepath.c (make_path): Port to hosts where leading "//" is special.
+ * yesno.c: Include getline.h, not ctype.h.
+ (yesno): Don't remove leading white space; POSIX doesn't allow it.
+ Use getline to remove arbitrary restriction on response length.
+

+
+ * getaddrinfo.c: Don't fail when SOCK_STREAM or SOCK_DGRAM are

+ check. ai_protocol is usually set to 0 or depending on
+ ai_family/ai_socktype to IPPROTO_TCP / IPPROTO_UDP. Checking for

+
+2005-05-09 Yoann Vandoorselaere <yoann.v@prelude-ids.com>
+ Bruno Haible <bruno@clisp.org>
+
+ * inet_ntop.h: New file.

+
+2005-05-08 Jim Meyering <jim@meyering.net>
+
+ * classpath.c (PATH_SEPARATOR): Remove insignificant trailing blank.
+
+2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
+
+ Merge from coreutils. Among other things,
+ add bulletproofing for cases where stdin, stdout, or stderr are closed.
+ * fd-safer.c: New file.
+ * fcntl-safer.h, open-safer.c: Remove.
+ * chdir-long.c: Fix comment "fetish" -> "coreutils".
+ * dup-safer.c: Include unistd-safer.h first.
+ Don't include errno.h.
+ (dup_safer) [!defined F_DUPFD]: Let fd_safer do the real work.
+ * file-type.h: Don't assume invoker included sys/stat.h first.
+ * file-type.c: Rely on file-type.h change.
+ * getloadavg.c: Include unistd-safer.h.
+ (getloadavg): Use safer open.
+ * getusershell.c: Include "stdio-safer.h".
+ (getusershell): Use safer fopen.
+ * long-options.c (long_options): Use NULL rather than 0.
+ * modechange.h (mode_free): Remove; all callers changed to invoke
+ 'free'.
+ * modechange.c: Likewise.
+ xstrtol.h, stdbool.h, stddef.h: Don't include; no longer needed.
+ (MODE_DONE): New constant.
+ (struct mode_change): Remove 'next' member.
+ (make_node_op_equals): New function; like the old one of the
+ same name, except it allocates an array.
+ (mode_compile, mode_create_from_ref): Use it.
+ (mode_compile): Allocate result as an array, not a linked list.
+ Parse octal string ourself, so that we catch mistakes like "+0".
+ (mode_adjust): Arg is an array, not a linked list.
+ * modechange.c: Include stat-macros.h, xalloc.h.
+ (S_ISDIR, S_ISUID, S_ISGID, S_ISVTX, S_IRUSR, S_IWUSR, S_IXUSR):
+ (S_IRGRP, S_IWGRP, S_IXGRP, S_IROTH, S_IWOTH, S_IXOTH, S_IRXWU):
+ (S_IRWXG, S_IRWXO, CHMOD_MODE_BITS):
+ Remove. This is now stat-macros.h's job.
+ (talloc): Remove. All callers replaced by xalloc, so that
+ our invokers don't have to worry about reporting memory failures.
+ (make_node_op_equals): Remove.
+ (MODE_ORDINARY_CHAGE, MODE_X_IF_ANY_X, MODE_COPY_EXISTING):
+ New constants.
+ (struct mode_change): Moved here from modechange.h.
+ (mode_append_entry): Remove.
+ (mode_compile): Remove MASKED_OPS arg, since it encouraged
+ apps to have incorrect behavior. Use simpler algorithm for head
+ and tail. Don't futz with umask; that's now the job of mode_adjust.
+ Detect more invalid usages rather than having somewhat-random behavior.
+ Don't insert an "a=" action, as that leads to incorrect behavior.
+ (mode_compile, mode_create_from_ref): Return NULL on error instead
+ of an enum, since now there's only one way to have an error. All
+ callers changed.
+ (mode_adjust): Accept new arg UMASK_VALUE, and interpret it
+ at the correct time. Simplify calculation of "+u" and its ilk.
+ Don't mishandle "+X".
+ (mode_free): Remove "register" and localize decls.
+ * modechange.h (MODE_X_IF_ANY_X, MODE_COPY_EXISTING):
+ (struct mode_change): Move to modechange.c; callers don't
+ need to see this stuff.
+ (MODE_MASK_EQUALS, MODE_MASK_PLUS, MODE_MASK_MINUS, MODE_MASK_ALL):
+ (MODE_INVALID, MODE_MEMORY_EXHAUSTED, MODE_BAD_REFERENCE): Remove.
+ (mode_change, mode_adjust): Reflect the new signatures noted above.
+ * nanosleep.c (rpl_nanosleep): Include "timespec.h" before macros
+ that might redefine system include files.
+ (siginterrupt) [!HAVE_SIGINTERRUPT]: New macro.
+ (my_usleep): Use NULL rather than (void *) 0.
+ (rpl_nanosleep) [!defined SA_NOCLDSTOP]:
+ Use siginterrupt to specify that system calls should be interrupted.
+ (rpl_nanosleep): Move initialization of suspended closer to call of
+ my_usleep.
+ * readutmp.h (read_utmp): New arg OPTIONS. All uses changed.
+ * readutmp.c: Likewise. Include signal.h, stdbool.h.
+ (desirable_utmp_entry): New function.
+ (read_utmp) [defined UTMP_NAME_FUNCTION]: Redo memory allocation
+ using x2nrealloc, to simplify logic.
+ (read_utmp) [!defined UTMP_NAME_FUNCTION]: Check for overflow in
+ size calculation. Do not assume utmp file is a regular file.

+ [!_LIBC] Include "stat-macros.h" instead.
+ * unistd-safer.h (fd_safer): New decl.

+
+2005-04-25 Albert Chin <china@thewrittenword.com>

+
+2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
+
+ * getdate.y (zone): Allow relunit_snumber after tZONE, so
+ that "UTC +1 second" continues to work. Problem reported
+ by Dmitry V. Levin.
+ (relunit_snumber): New rule.
+ (relunit): Use it.
+
+2005-04-12 Paul Eggert <eggert@cs.ucla.edu>
+
+ * getdate.y (universal_time_zone_table): New constant.
+ (time_zone_table): Remove GMT, UT, UTC entries; they're now in
+ universal_time_zone_table.
+ (lookup_zone): Prefer universal_time_zone_table to
+ local_time_zone_table, so that "GMT" time stamps are allowed in
+ London during the summer. Problem reported by Ian Abbott.
+
+2005-04-12 Jim Meyering <jim@meyering.net>
+
+ * human.c (humblock): Set *options even when returning due to
+ xstrtoumax conversion failure. Thanks to a used-uninitialized
+ warning from gcc-4.
+
+2005-04-09 Jim Meyering <jim@meyering.net>
+
+ * posixtm.c (posixtime) [lint]: Avoid spurious warning from gcc-4's
+ -Wuninitialized: initialize tm0.tm_year.
+
+2005-04-04 Paul Eggert <eggert@cs.ucla.edu>
+
+ * getdate.y (parser_control): rels_seen is now a boolean, not a
+ count, since there's no maximum. All uses changed.
+ Add member dsts_seen.
+ (local_zone): Accumulate dsts_seen rather than relying on tm_isdst
+ not being INT_MAX.
+ (get_date): Initialize dsts_seen, and check that it doesn't go over 1.
+ Use pc_rels_seen to decide whther a date is absolute.
+
+ * getdate.y (number): Don't overwrite year.
+ (get_date): Initialize pc.year.digits to 0, not 4, to enable above
+ check.
+
+2005-04-02 Simon Josefsson <jas@extundo.com>
+
+ * getaddrinfo.h: Fix OpenBSD compilation failure, inspired by tiny
+ patch from Yoann Vandoorselaere <yoann@prelude-ids.org>.
+
+2005-03-27 Jim Meyering <jim@meyering.net>
+
+ * argmatch.c: Clarify comment: null-terminated -> NULL-terminated.
+
+2005-03-26 Paul Eggert <eggert@cs.ucla.edu>
+
+ * intprops.h (INT_STRLEN_BOUND, INT_BUFSIZE_BOUND):
+ "one's complement" -> "ones' complement" in comment, as per Knuth.
+ "value of type" -> "type or expression" in comment.
+ * mktime.c, strftime.c: Propagate intprops.h comment nits.
+
+2005-03-26 Jim Meyering <jim@meyering.net>
+
+ Comment nits.
+ * intprops.h: Add the apostrophe in `(one|two)'s complement'.
+ Correct typos: s/or/of/.
+
+2005-03-23 Jim Meyering <jim@meyering.net>
+
+ * canonicalize.c: Remove duplicate `#include "stat-macros.h"'.
+
+2005-03-21 Jim Meyering <jim@meyering.net>
+
+ Changes imported from coreutils.
+
+ * cycle-check.c: Don't include xalloc.h.
+
+ * path-concat.c: Don't include assert.h.
+ (path_concat): Remove assertion that would have triggered
+ for ABASE starting with more than one slash.
+ Reported by Andreas Schwab.
+
+ * path-concat.c (path_concat): Set *BASE_IN_RESULT
+ properly when ABASE is an absolute file name.
+ Correct the description of this function.
+ Include <assert.h>.
+ Add an assertion and a test driver.
+ This fixes a bug introduced on 2004-07-02.
+ Andreas Schwab reported the resulting failure of cp --parents:
+ http://lists.gnu.org/archive/html/bug-coreutils/2005-01/msg00130.html
+
+2005-03-18 Paul Eggert <eggert@cs.ucla.edu>
+
+ * strftime.c (my_strftime): If the underlying strftime returns 0
+ (which shouldn't happen), generate nothing instead of returning 0
+ immediately, so that nstrftime (NULL, ...) doesn't return 0.
+
+2005-03-16 Bruno Haible <bruno@clisp.org>
+
+ * stdint_.h: Use HAVE_LONG_LONG_64BIT instead of HAVE_LONGLONG_64BIT.
+
+2005-03-15 Paul Eggert <eggert@cs.ucla.edu>
+
+ * strftime.c (my_strftime): Prepend space to format so that we can
+ reliably distinguish strftime failure from empty output on POSIX
+ hosts.
+
+2005-03-08 Paul Eggert <eggert@cs.ucla.edu>
+
+ * iconvme.c (SIZE_MAX): New macro, if not already defined.
+ (iconv_string): Don't guess a size-zero buffer, as that might cause
+ buffer overrun. Instead, avoid multiplying by MB_LEN_MAX if the
+ result would be 'too large', where 'too large' is (heuristically)
+ the square root of SIZE_MAX, divided by MB_LEN_MAX to allay
+ overflow concerns. This will prevent some unwanted malloc failures
+ when the inputs are very large.
+
+2005-03-15 Bruno Haible <bruno@clisp.org>
+
+ * regex.c (byte_re_match_2_internal): Rename local variable 'not' to
+ 'negate'.
+
+ * regex.c (byte_re_match_2_internal): Reduce scope of same_str_p
+ variable.
+
+ * regex.c (EXTEND_BUFFER, regcomp): Cast the realloc/malloc results.
+
+2005-03-14 Paul Eggert <eggert@cs.ucla.edu>
+
+ * mktime.c (TYPE_TWOS_COMPLEMENT, TYPE_ONES_COMPLEMENT,
+ TYPE_SIGNED_MAGNITUDE, TYPE_MINIMUM, TYPE_MAXIMUM): Sync from
+ intprops.h.
+ * strtol.c: Likewise.
+
+2005-03-14 Simon Josefsson <jas@extundo.com>
+
+ * timegm.h: Use proper prototype CPP guards, reported by Dave Love
+ <fx@gnu.org>.
+
+2005-03-14 Jim Meyering <jim@meyering.net>
+
+ * strftime.c (my_strftime) [HAVE_STRFTIME && ! (_NL_CURRENT
+ && HAVE_STRUCT_ERA_ENTRY)]: Initialize the first byte of ubuf[]
+ to be nonzero so that we (and caller) can detect the difference
+ between a valid zero-length expansion and an error return, even
+ when the underlying strftime fails before writing anything into
+ that location.
+
+2005-03-10 Jim Meyering <jim@meyering.net>
+
+ * save-cwd.c [!HAVE_FCHDIR]: Define open, fchdir, and chdir_long
+ so that this module works on systems without fchdir.
+
+2005-03-09 Paul Eggert <eggert@cs.ucla.edu>
+
+ Factor int-properties macros into a single file, except for
+ glibc-related files.
+ * intprops.h: New file.
+ * getloadavg.c: Include it instead of limits.h.
+ (INT_STRLEN_BOUND): Remove.
+ * human.c: Include intprops.h.

+ * human.h (LONGEST_HUMAN_READABLE): Use 146/485 rather than 302/1000.
+ * inttostr.h: Include intprops.h instead of limits.h.
+ (INT_STRLEN_BOUND, INT_BUFSIZE_BOUND): Remove.
+ * mktime.c (TYPE_IS_INTEGER, TYPE_TWOS_COMPLEMENT): New macros,
+ for consistency with intprops.h.

+ * sig2str.h: Include <signal.h>, intprops.h.
+ (INT_STRLEN_BOUND): Remove.
+ * strftime.c (TYPE_SIGNED): Remove.
+ (INT_STRLEN_BOUND): Switch to same implementation as intprops.h.
+ * strtol.c: Adjust comments to match intprops.h.
+ * userspec.c: Include intprops.h.
+ (TYPE_SIGNED, TYPE_MINIMUM, TYPE_MAXIMUM): Remove.
+ * utimecmp.c, xnanosleep.c, xstrtol.c: Likewise.
+ * utimecmp.c (utimecmp): Use TYPE_IS_INTEGER, TYPE_TWOS_COMPLEMENT
+ instead of rolling our own expressions.
+ * xstrtol.c: Include xstrtol.h first, to test interface.
+
+ * strftime.c: Include <stdbool.h>. Use bool where appropriate,
+ instead of int.
+ (my_strftime): Do not mishandle years close to INT_MAX, by doing
+ the right thing even if adding 1900 would overflow. Similarly
+ for tm_mon + 1 and tm_yday + 1.
+ Make %Y always equivalent to %C%y, and similarly for %G and %g.
+ (DO_NUMBER, DO_NUMBER_SPACEPAD): Set digits to d, not a conditional.
+ (DO_SIGNED_NUMBER): New macro.
+ (my_strftime) [HAVE_TZNAME]: Don't dump core if tp->tm_dst > 1.
+
+2005-03-07 Bruno Haible <bruno@clisp.org>
+
+ * pagealign_alloc.c (MAP_FILE, MAP_FAILED): Define fallbacks.
+
+2005-03-03 Derek R. Price <derek@ximbiot.com>
+ Bruno Haible <bruno@clisp.org>
+
+ * pagealign_alloc.h: New file.
+ * pagealign_alloc.c: New file.
+
+2005-01-28 Bruno Haible <bruno@clisp.org>
+
+ * stpncpy.h (stpncpy): Define as a macro without arguments, so that
+ stpncpy.c uses it.
+
+2005-03-01 Paul Eggert <eggert@cs.ucla.edu>
+
+ Remove workaround for bug in Linux kernel 2.6.8 or thereabouts.
+ The workaround isn't strictly needed for POSIX conformance, and
+ it's too much of a pain to configure and maintain. We'll ask
+ people to fix their kernels instead.
+ * xnanosleep.c: Don't include gethrxtime.h or xtime.h.
+ (NANOSLEEP_BUG_WORKAROUND): Remove.
+ (xnanosleep): Remove the workaround.
+
+2005-02-12 Bruno Haible <bruno@clisp.org>
+
+ * vasnprintf.c (EOVERFLOW): Define to a fallback if needed.
+
+2005-02-25 Paul Eggert <eggert@cs.ucla.edu>
+
+ * gethrxtime.h, gethrxtime.c, xtime.h: New files.
+ * timespec.h (gettime): Return void, since it always
+ succeeds now. All uses changed.
+ * gettime.c (gettime) Likewise.
+ [HAVE_NANOTIME]: Prefer nanotime.
+ Assume gettimeofday succeeds, as POSIX requires.
