See + <http://lists.gnu.org/archive/html/bug-gnulib/2011-01/msg00554.html>. + + 2011-01-29 Paul Eggert <[email protected]> + + TYPE_MAXIMUM: avoid theoretically undefined behavior + * intprops.h (TYPE_MINIMUM, TYPE_MAXIMUM): Do not shift a + negative number, which the C Standard says has undefined behavior. + In practice this is not a problem, but might as well do it by the book. + Reported by Rich Felker and Eric Blake; see + <http://lists.gnu.org/archive/html/bug-gnulib/2011-01/msg00493.html>. + * mktime.c (TYPE_MAXIMUM): Redo slightly to match the others. + + mktime: #undef mktime before #defining it + * mktime.c (mktime) [DEBUG]: #undef mktime before #defining it. + + mktime: systematically normalize tm_isdst comparisons + * mktime.c (isdst_differ): New function. + (__mktime_internal): Use it systematically for all isdst comparisons. + This completes the fix for libc BZ #6723, and removes the need for + normalizing tm_isdst. See + <http://sourceware.org/bugzilla/show_bug.cgi?id=6723> + (not_equal_tm) [DEBUG]: Use isdst_differ here, too. + + mktime: fix some integer overflow issues and sidestep the rest + + This was prompted by a bug report by Benjamin Lindner for MinGW + <http://lists.gnu.org/archive/html/bug-gnulib/2011-01/msg00472.html>. + His bug is due to signed integer overflow (0 - INT_MIN), and I + I scanned through mktime.c looking for other integer overflow + problems, fixing all the bugs I found. + + Although the C Standard says the resulting code is still not safe + in the presence of integer overflow, in practice it should be good + enough for all real-world two's-complement implementations, except + for debugging environments that deliberately trap on integer + overflow (e.g., gcc -ftrapv). + + * mktime.c (WRAPV): New macro. + (SHR): Also check that long_int and time_t shift right in the + usual way, before using the fast-but-unportable method. + (TYPE_ONES_COMPLEMENT, TYPE_SIGNED_MAGNITUDE): Remove, no longer + used. The code already assumed two's complement, so there's + no need to test for alternatives. All uses removed. + (TYPE_MAXIMUM): Don't rely here on overflow behavior not defined by + the C standard. Problem reported by Rich Felker in + <http://lists.gnu.org/archive/html/bug-gnulib/2011-01/msg00488.html>. + (twos_complement_arithmetic): Also check long_int and time_t. + (time_t_avg, time_t_add_ok, time_t_int_add_ok): New functions. + (guess_time_tm, ranged_convert, __mktime_internal): Use them. + (__mktime_internal): Avoid integer overflow with unary subtraction + in two instances where -1 - X is an adequate replacement for -X, + since the calculations are approximate. + + 2011-01-28 Paul Eggert <[email protected]> + + mktime: avoid problems on NetBSD 5 / i386 + * mktime.c (long_int): New type. This works around a problem + on NetBSD 5 / i386, where 'long int' and 'int' are both 32 bits + but time_t is 64 bits, and where I expect the existing code is + wrong in some cases. + (leapyear, ydhms_diff, guess_time_tm, __mktime_internal): Use it. + (ydhms_diff): Bring back the compile-time check for wide-enough + year and yday. + + mktime: fix misspelling in comment + * mktime.c (__mktime_internal): Fix misspelling in comment. + This merges all recent glibc changes of importance. + +2011-01-29 Eli Zaretskii <[email protected]> + + * makefile.w32-in: + * getopt_.h: New files. + +2011-01-27 Paul Eggert <[email protected]> + + fix two m4/gnulib-*.m4 file names that clashed under MS-DOS + * Makefile.in: Regenerate. + +2011-01-24 Paul Eggert <[email protected]> + + Remove HAVE_RAW_DECL_CHOWN etc. from config.h + * Makefile.in: Regenerate. + +2011-01-17 Paul Eggert <[email protected]> + + Makefile.in: tidy up the building of lib + * Makefile.in: Regenerate. + * COPYING: New file, a copy of COPYING. + + Regenerate. + * getopt.c, getopt.in.h, getopt1.c, getopt_int.h: + * gettext.h, unistd.in.h: + New files, copied from gnulib by gnulib-tool. + * Makefile.in: + Regenerate. + + Regenerate. + * mktime-internal.h, mktime.c: + * stddef.in.h, time.h, time.in.h, time_r.c: + New files, copied from gnulib by gnulib-tool. + * Makefile.in, gnulib.mk: + Regenerate. + + Regenerate. + * dtoastr.c, ftoastr.c, ftoastr.h, intprops.h: + * ldtoastr.c: + New files, copied from gnulib by gnulib-tool. + * dummy.c: Remove. + * Makefile.in, gnulib.mk: + Regenerate. + + Regenerate. + * Makefile.in, dummy.c, gnulib.mk: + New files, generated automatically, with 'make sync-from-gnulib' + followed by 'make'. + + Automate syncing from gnulib. + * Makefile.am: New file. |
