If my guess is wrong, we'll need to come up with a + variant of strftime that doesn't need the multibyte modules. + + I discovered this problem when attempting modify Emacs to use the + strftime module. With the previous gnulib, this caused Emacs to + need 31 new files, ranging from lib/config.charset to + m4/wint_t.m4. This was overkill and I expect would be offputting + to the Emacs maintainers. After this change, only 6 new files are + needed, namely strftime.[ch], srtftime.m4, stdbool.in.h, + stdbool.m4, and tm_gmtoff.m4. + + * lib/strftime.c (MULTIBYTE_IS_FORMAT_SAFE): Define to 1 always. + Suggested by Bruno Haible in + . + * m4/strftime.m4 (gl_FUNC_STRFTIME): Do not require AC_TYPE_MBSTATE_T, + and do not check for wchar.h. + * modules/strftime (Files): Remove m4/mbstate_t.m4. + (Depends-on): Remove mbrlen, mbsinit, wchar. + +2011-01-18 Bruno Haible + + Tests for module 'get-rusage-as'. + * modules/get-rusage-as-tests: New file. + * tests/test-get-rusage-as.c: New file. + + New module 'get-rusage-as'. + * modules/get-rusage-as: New file. + * lib/resource-ext.h: New file. + * lib/get-rusage-as.c: New file. + +2011-01-17 Eric Blake + + sigaction: relax license from LGPLv3+ to LGPLv2+ + * modules/sigaction (License): Relax to LGPLv2+. + +2011-01-14 Bruno Haible + + filemode: Make function declarations usable in C++ mode. + * lib/filemode.h: Enclose function declarations in extern "C" block. + Reported by John W. Eaton . + +2011-01-12 Rob Vermaas + + save-cwd: no longer include "xgetcwd.h" + * lib/save-cwd.c: Don't include "xgetcwd.h"; it's no longer used. + This avoids a compilation failure in projects that use save-cwd + without also using the xgetcwd module. + +2011-01-11 Paul Eggert + + ftoastr: split into 3 modules ftoastr, dtoastr, ldtoastr + This is so that a program like Emacs, which needs only dtoastr, + does not have to bother with distributing and compiling ftoastr + and ldtoastr. + * MODULES.html.sh: Document these modules (ftoastr wasn't documented). + * modules/dtoastr, modules/ldtoastr: New files. + * modules/ftoastr: Now works just for 'float'. + (Files): Remove lib/dtoastr.c, lib/ldtoastr.c. + (Makefile.am): Remove ftoastr.h (not needed and no effect), + dtoastr.c, ldtoastr.c. + +2011-01-11 Jim Meyering + + save-cwd: remove #if-!HAVE_FCHDIR'd code; use the fchdir module + There is no need to work around the lack of the fchdir function, + since gnulib can now provide a replacement when required. + * lib/save-cwd.c: Remove #if !HAVE_FCHDIR...#endif code. + * modules/save-cwd (Depends-on): Add fchdir. + +2011-01-11 Paul Eggert + + openat, save-cwd: avoid xmalloc + + This removes a direct (but undocumented) dependency of openat on + xalloc, along with an indirect dependency via save-cwd. It also + removes a dependency of save-cwd on xgetcwd, and thereby + indirectly on xalloc. This change causes the openat substitute + to fall back on save_cwd when memory is tight, and for save_cwd to + fail instead of dying when memory is tight, but that's good enough. + + * lib/openat-proc.c: Include stdlib.h (for malloc), not + xalloc.h (for xmalloc). + (openat_proc_name): Use malloc, not xmalloc. + * lib/save-cwd.c (save_cwd): Use getcwd, not xgetcwd. + * modules/save-cwd (Files): Depend on getcwd, not xgetcwd. + + openat: Increase OPENAT_BUFFER_SIZE from 512 to at least 1024 + This avoids heap allocation for file names whose lengths are in + the range 512..1023, with the upper bound increasing to at most + 4031 depending on the platform's PATH_MAX. (We do not want + pathmax.h here as it might supply a non-constant PATH_MAX.) + * lib/openat-priv.h (SAFER_ALLOCA_MAX, SAFER_ALLOCA): New macros. + Perhaps they should be moved to malloca.h? + (OPENAT_BUFFER_SIZE): Use them. + +2011-01-10 Bruno Haible + + doc: Update users.txt. + * users.txt: Add recutils. + +2011-01-09 Karl Berry + + * doc/posix-functions/gai_strerror.texi: Insert missing @item. + + * doc/configmake.texi: New file. + * doc/gnulib.texi: Include it. + * modules/configmake: Move documentation from here. + 2011-01-09 Bruno Haible Update to Unicode 6.0.0.
