+2005-10-03 Paul Eggert <eggert@cs.ucla.edu>
+
+ * getdelim.c: Include getdelim.h first. Include <limits.h>.
+ (SSIZE_MAX): New macro, if not already defined.
+ (getdelim): Fix buffer overrun on 64-bit hosts with lines longer
+ than 2 GiB.
+
+2005-10-02 Paul Eggert <eggert@cs.ucla.edu>
+
+ * exclude.c: Include verify.h.
+ (verify): Remove. All callers changed to use verify.h's version.
+ * strtoimax.c: Likewise.
+ * utimecmp.c: Likewis.e
+
+ Sync from coreutils.
+ * .cppi-disable: Add getaddrinfo.h, getdelim.h, getline.h, getpass.c
+ mbchar.h, mbuiter.h, strcase.h, strnlen.h, strnlen1.h.
+ * .cvsignore: Add fts.h, search.h, t-fpending.
+ * settime.c (settime): Fix { typo in previous patch. Also, don't
+ bother returning ENOSYS if settimeofday or stime fails; just let
+ them return whatever errno they want to return.
+ * utimens.c: Include unistd.h, for dup2.
+ (futimens): Fix typo: HAVE_FUTIMESAT was misspelled in an #if.
+ (futimens) [! HAVE_FUTIMESAT]: If !file, set errno before returning -1.
+
+2005-10-02 Jim Meyering <jim@meyering.net>
+
+ Sync from coreutils.
+ * fts-cycle.c [HAVE_CONFIG_H]: Include <config.h>.
+ * openat-die.c: Use `#ifdef HAVE_CONFIG_H', not `#if HAVE_CONFIG_H'.
+ * openat.c (fdopendir): Do not define if HAVE_FDOPENDIR.
+ Remove AT_FDCWD test.
+ Do not consume the fd unless successful.
+ * openat.h (fdopendir): Do not define if HAVE_FDOPENDIR.
+ * settime.c (settime): Move the HAVE_STIME block `up' into an #elif
+ block, so that we don't even try to compile it if settimeofday is
+ available. This works around a compilation failure on OSF1 V5.1,
+ due to stime requiring a `long int*' while tv_sec is `int'.
+
+2005-09-30 Eric Blake <ebb9@byu.net> (tiny change)
+
+ * getdelim.c (getdelim): Remove unused variables.
+
+2005-10-01 Simon Josefsson <jas@extundo.com>
+
+ * getaddrinfo.h: Protect #include's of sys/socket.h and netdb.h.
+ Only define struct addrinfo if !HAVE_STRUCT_ADDRINFO. Protect
+ AI_* and EAI_* definitions. Protect function declarations.
+
+2005-09-29 Paul Eggert <eggert@cs.ucla.edu>
+
+ * xtime.h (XTIME_PRECISION): Now of type int, not long long int,
+ so that the code works even with ancient cpp. Portability problem
+ with GCC 2.7.2.1 reported by Thomas M.Ott.
+
+2005-09-27 Jim Meyering <jim@meyering.net>
+
+ * getcwd.c: Change #ifdef<TAB>HAVE_CONFIG_H to #ifdef HAVE_CONFIG_H.

+
+2005-09-26 Paul Eggert <eggert@cs.ucla.edu>
+
+ * verify.h (verify_expr): Remove, replacing with:
+ (verify_true): New macro that returns true instead of void.
+ (verify_type__): Remove.
+ (verify): Use verify_true rather than verify_type__.
+
+2005-09-24 Paul Eggert <eggert@cs.ucla.edu>
+
+ * utimens.c (ENOSYS): Define if not already defined.
+ (futimens): Support having a null PATH if the file descriptor
+ is nonnegative.
+
+ * regex_internal.h (__GNUC_PREREQ, always_inline, inline, pure):
+ Remove.
+ (__attribute): Define to empty unless GCC 3.1 or later.
+ This works around a core dump on OpenBSD 3.4, which has GCC
+ 2.95.3, which dumps core when given __attribute__(()). It also
+ simplifies other tests, since we really don't want to bother with
+ worrying about which ancient version of GCC supported what.
+ Original problem reported by Yoann Vandoorselaere, with part of
+ the fix suggested by Derek Price.
+
+2005-09-24 Jim Meyering <jim@meyering.net>
+
+ * verify.h (verify_type__): Use `unsigned int' as the bitfield type
+ so we can once again use a positive bitfield width of 1 -- now we
+ don't have to explain why we were using a bitfield width of 2.
+
+2005-09-23 Paul Eggert <eggert@cs.ucla.edu>
+
+ * getaddrinfo.c [HAVE_NETINET_IN_H]: Include <netinet/in.h>.
+ Problem reported by Eric Blake.
+ (getaddrinfo): Initialize se so that it's not garbage.
+ Redo internal storage allocation so that it doesn't make unportable
+ assumptions about alignment.
+ Fix a memory leak.
+
+ * utimens.c (futimens): Use futimesat if available.
+ Prefer it to futimes since it doesn't have the futimes bug.
+
+ * verify.h (GL_CONCAT0, GL_CONCAT): Remove.
+ (verify): Don't use the __LINE__ trick, as it doesn't work in general.
+ Instead, declare a function that returns a pointer to an array,
+ and use verify_type__ to declare the size of the array.
+ Problem and germ of a solution reported by Bruno Haible.
+ (verify_type__): Use 2, not 1, for bitfield size, to avoid
+ a warning with Irix 6.5 cc. Problem reported by Bruno Haible.

+
+ * .cppi-disable: Add regcomp.c, regex_internal.c, regex_internal.h,
+ stat-time.h.
+ * argmatch.h: Include verify.h
+ (ARGMATCH_VERIFY): Use verify rather than rolling our own.
+ (ARGMATCH_ASSERT): Remove; unused.
+ * canonicalize.c: Assume STDC_HEADERS.
+ * exclude.c: Include "strcase.h".
+ * regex_internal.h [!defined _LIBC]: Likewise.
+ * getusershell.c: Include stdio--.h rather than stdio.h
+ and stdio-safer.h.
+ (getusershell): Call fopen, not fopen_safer.
+ * save-cwd.c: Include fcntl--.h rather than fcntl.h.
+ Do not include unistd-safer.h.
+ (save_cwd): Don't call fd_safer; no longer needed
+ now that we include fcntl--.h.
+
+ * getdate.y (relative_time): New type.
+ (RELATIVE_TIME_0): New constant.
+ (parser_control): Use relative_time instead of doing it ourselves.
+ (%union): Add new relative_time rel member.
+ (tYEAR_UNIT, tMONTH_UNIT, tHOUR_UNIT, tMINUTE_UNIT, tSEC_UNIT):
+ Now typeless.
+ (relunit, relunit_snumber): Now of type rel.
+ (zone, rel, relunit, get_date): Adjust to above changes.
+
+ * getloadavg.c: Include fcntl--.h rather than fcntl.h.
+ Do not include unistd-safer.h.
+ (getloadavg): Don't call fd_safer; no longer needed
+ now that we include fcntl--.h.
+
+ * mkdir-p.c (ENOSYS): Define to EEXIST if not defined.
+ (make_dir_parents): Treat ENOSYS like EEXIST.
+
+ Improve quality of diagnostics on restore_cwd failure.
+ * mkdir-p.h (make_dir): Remove. All uses replaced by mkdir.
+ (make_dir_parents): Last arg is now int * (for errno), not bool *.
+ * mkdir-p.c (make_dir, make_dir_parents): Likewise.
+ Rewrite "mkdir -p" algorithm to avoid the need for "stat"
+ each time through the loop. Do not diagnose restore_cwd failure;
+ that is the caller's job (and perhaps the caller does not care).
+
+ * mkdir-p.c (CLEANUP_CWD, CLEANUP): Remove.
+ (make_dir_parents): Revamp to avoid need for CLEANUP_CWD, CLEANUP.
+ If the file already exists but is not a directory, don't bother
+ to try to make its parents.
+ Close potential file descriptor leak if we can't chdir("/") (!).
+ Don't always return true if chdir($PWD) fails; return true only
+ if the requested action was done successfully (except for the
+ chdir($PWD)).
+ Don't log final directory unless we actually made it.
+ Refactor to avoid duplicate code to fix up permissions.
+ Don't attempt to fix up parent permissions if chdir($PWD) fails.
+
+ * strftime.c (my_strftime): Rewrite the previous change slightly,
+ to make it a bit faster and (I hope) clearer.
+ * strftime.c (my_strftime): Add support for %:z, %::z, %:::z.
+ Fix bug in formats like %2N.
+
+ * verify.h: New file.
+
+2005-09-22 Jim Meyering <jim@meyering.net>
+
+ Sync from coreutils.
+
+ * backupfile.c: Use ARGMATCH_VERIFY, just in case.
+
+ * posixtm.c (posixtime) [lint]: Initialize *all* of tm0, not just
+ the .tm_year member, since otherwise gcc-4.0 would now warn about
+ tm_zone, tm_gmtoff, tm_isdst, tm_yday, tm_wday.
+
+ * quotearg.c (quotearg_n_options): Change code to be suboptimal, in
+ order to avoid an unsuppressible warning from gcc on 64-bit systems.
+
+ * getdate.y (get_date): Undo part of the 2005-04-04 change, so that
+ the command "date -d'2005-03-27 +1 day'" succeeds once again, even
+ when run in a time zone for which daylight savings time is in effect
+ for the starting date.
+
+ * mkdir-p.c (make_dir_parents): Don't let a failed chdir($PWD)
+ stop us from restricting permissions of just-created absolute-named
+ directories.
+ * mkdir-p.c (CLEANUP_CWD): Return *true*, not false when failing
+ to restore initial working directory.
+ * mkdir-p.c (make_dir_parents): New parameter: different_working_dir,
+ to tell caller if/when we change the working directory and are
+ unable to return to the initial one.
+ * mkdir-p.h (make_dir_parents): Update prototype.
+ * mkdir-p.c (CLEANUP_CWD): Change one more `return 1' to
+ `return false'. This fixes a bug introduced on 2004-07-30.
+
+ * openat.c (fdopendir): Be sure to close the supplied
+ file descriptor before returning. This makes our replacement
+ implementation a little closer to Solaris's, where fdopendir
+ ties the file descriptor to the returned DIR* pointer.
+ * openat.c (unlinkat): New function.
+ * openat.h (unlinkat): Add prototype.
+ * openat-die.c (openat_save_fail): Rename from openat_save_die.
+ (openat_restore_fail): Rename from openat_restore_die.
+ * openat.c, openat.h: Reflect s/_die/_fail/ renaming.
+
+ Provide an alternative to exiting immediately upon save_cwd or
+ restore_cwd failure. Now, an application can arrange e.g.,
+ to perform a longjump in that case.
+ * openat.c: Include dirname.h.
+ Use IS_ABSOLUTE_FILE_NAME rather than testing for leading slash.
+ (rpl_openat, fdopendir, fstatat): Call openat_save_die
+ and openat_restore_die rather than calling error directly.
+ Don't include "error.h" or "exitfail.h"; they're no longer needed.
+
+ * openat-die.c (openat_save_die, openat_restore_die): New file.
+ * openat.h (openat_save_die, openat_restore_die): Declare and define.
+
+ * strftime.c [FPRINTFTIME] (fprintftime): Provide a new interface:
+ size_t fprintftime (FILE *fp, char const *fmt, struct tm const *tm,
+ int utc, int nanoseconds);
+ Background:
+ date should not have to allocate a megabyte of virtual memory to
+ handle a format argument like +%1048575T. When implemented with
+ strftime, it must allocate such a buffer, use strftime to fill it
+ in, print it, then free it.
+ With fprintftime, it simply prints everything and exits.
+ With no need for memory allocation, that's one fewer way to fail.
+ * strftime.c (my_strftime): Parse the colons of %:::z *after* the
+ optional field width, not before, so we accept %9:z, not %:9z.
+ (my_strftime): Be sure to use L_('x') for literals.

+
+ 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.
+ (regoff_t) [defined _REGEX_LARGE_OFFSETS]: Define to off_t, not int.
+ (__re_idx_t, __re_size_t, __re_long_size_t): New types.

+
+2005-08-21 Bruno Haible <bruno@clisp.org>
+
+ * lock.h: Add multiple inclusion guard.
+ * tls.h: Add multiple inclusion guard.
+
+2005-08-23 Paul Eggert <eggert@cs.ucla.edu>
+
+ * regex.h (REG_NOSYS)
+ [!defined _XOPEN_SOURCE && 200112L <= _POSIX_C_SOURCE]:
+ Define, since POSIX requires it as of 2001.
+ (_REG_ENOSYS) [! (defined _XOPEN_SOURCE || 200112L <= _POSIX_C_SOURCE)]:
+ New private symbol, used to keep the enum signed in all cases.
+ * regex.h (RE_NO_EMPTY_RANGES): Fix doc bug reported by James Youngman
+ in <http://lists.gnu.org/archive/html/bug-gnulib/2005-07/msg00132.html>.
+

+
+ Fix problems reported by Sam Steingold in
+ <http://lists.gnu.org/archive/html/bug-gnulib/2005-08/msg00007.html>.
+ * regexec.c (sift_states_bkref): Fix portability bug: the code
+ assumed that reg_errcode_t is a signed type, which is not
+ necessarily true if _XOPEN_SOURCE is not defined.
+ * regex_internal.c (calc_state_hash): Put 'inline' before type, since
+ some compilers warn about it otherwise.
+
+2005-08-20 Jim Meyering <jim@meyering.net>
+
+ * regexec.c (regexec, re_search_stub) [!_LIBC]: Omit declaration

+
+2005-08-19 Paul Eggert <eggert@cs.ucla.edu>
+
+ * regex_internal.c (re_acquire_state, re_acquire_state_context)
+ [defined lint]: Suppress bogus uninitialized-variable warnings.
+
+ * regcomp.c (duplicate_node): Return new index, not an error code,
+ and let the caller return REG_ESPACE if out of space. This
+ removes an uninitialied-variable warning with GCC 4.0.1, and also
+ avoids taking the address of a local variable. All callers
+ changed.
+
+2005-08-19 Jim Meyering <jim@meyering.net>

+ * strstr.c (strstr): Fix return value in multibyte case.
+ * strcasestr.c (strcasestr): Likewise.
+
+2005-08-17 Jim Meyering <jim@meyering.net>
+
+ Make the %s format (seconds since the epoch) work for a negative
+ number and when used with a zero-padded field width, e.g. %015s.
+
+ * strftime.c (my_strftime): Move the `do_number_sign_and_padding'
+ label so that it precedes the code to set `digits'. Otherwise,
+ %0Ns wouldn't work. Before this change, `date -d @-22 +%05s' would
+ print `00-22'. Now, it prints `-0022', as it should.
+
+2005-08-17 Paul Eggert <eggert@cs.ucla.edu>

+ (mbi_avail, mbi_advance): Let the iteration end before the terminating
+ NUL byte, not after it.
+
+2005-08-16 Bruno Haible <bruno@clisp.org>
+
+ * mbchar.h (mb_cmp, mb_casecmp): Order the invalid characters after
+ the valid ones. Makes the comparison operations transitive:
+ cmp (a, b) < 0 && cmp (b, c) < 0 ==> cmp (a, c) < 0.
+ * strcasecmp.c (strcasecmp): Use mb_casecmp.
+
+2005-08-16 Bruno Haible <bruno@clisp.org>
+
+ * strcase.h (strcasecmp): Add note in comments.
+ * strncasecmp.c: Use code from strcasecmp.c.
+ * strcasecmp.c: Use mbchar module. Define private mbiter variant.
+ (strcasecmp): Work correctly in multibyte locales.
