Do all putenv calls before Emacs creates any threads.
Use a safer way to modify the TZ environment variable in the
presence of multiple threads. For further thread-safety,
prefer localtime_r and gmtime_r to localtime and gmtime,
and prefer struct tm's tm_gmtoff (if available) to calling
both localtime_r and gmtime_r.
* configure.ac (LOCALTIME_CACHE): Remove.
We needn't worry about SunOS 4 any more; Sun dropped support in 2003.
All uses of LOCALTIME_CACHE removed. This simplifies the fix.
(tzalloc): Add check for this function.
* admin/merge-gnulib (GNULIB_MODULES): Add time_r, since Emacs now
calls localtime_r and gmtime_r directly.
* src/dbusbind.c (Fdbus__init_bus): Move xputenv call from here ...
(init_dbusbind): ... to this new function.
* src/emacs.c (main) [HAVE_DBUS]: Call it before creating threads.
* src/xterm.c (x_term_init): Move xputenv call from here ...
(init_xterm): ... to this new function.
* src/emacs.c (main) [USE_GTK]: Call it before creating threads.
* src/editfns.c (HAVE_TM_GMTOFF): Default to false.
(dump_tz_string): New constant.
(init_editfns): Use it. This centralizes the dump_tz stuff.
Call set_time_zone_rule here, so that its xputenv is done
before Emacs goes multithreaded.
(mktime_z) [!HAVE_TZALLOC]: New function, which is typically
thread-safe enough for Emacs.
(format_time_string, Fdecode_time, Fcurrent_time_string)
(Fcurrent_time_zone):
Prefer localtime_r and gmtime_r, which are more thread-safe, to
localtime and gmtime. Remove now-unnecessary calls to block_input.
(tm_gmtoff): New static function.
(Fdecode_time, Fcurrent_time_zone): Use it.
(Fencode_time): Use mktime_z, for better thread-safety.
(set_time_zone_rule): Now static. Rewrite to be mostly thread-safe,
i.e., not quite thread-safe but good enough for Emacs typical usage.
Do not reclaim storage that is in the environment; let it leak.
Always call tzset, since localtime_r does not.
* src/emacs.c (dump_tz, Fdump_emacs) [HAVE_TZSET]: Remove dump_tz stuff.
This is now done in init_editfns.
* src/systime.h (mktime_z, timezone_t, tzalloc, tzfree) [!HAVE_TZALLOC]:
New macros and declarations, for platforms lacking tzalloc & friends.
Fixes: debbugs:8705
* doc/lispref/streams.texi (Output Functions): Document new argument ENSURE to
terpri.
* doc/misc/cl.texi (Porting Common Lisp): Remove parse-integer.
* lisp/emacs-lisp/cl-extra.el (cl-fresh-line): New function.
* src/keymap.c (describe_vector_princ):
* src/keyboard.c (Fcommand_error_default_function): Adapt to change to
Fterpri.
* src/print.c (printchar_stdout_last): Declare.
(printchar): Record the last char written to stdout.
(Fterpri): Add optional argument ENSURE.
* test/automated/print-tests.el: New file.
(terpri): Tests for terpri. (Bug#18652)
src/w32inevt.c (maybe_generate_resize_event): Pass non-zero as the
DELAY argument to change_frame_size, so that the frame size
changes, if any are needed, are delayed until the next redisplay.
This is to avoid a too early QUIT inside change_frame_size, when
it calls Lisp in frame_windows_min_size, in case one of the events
we've read sets the quit-flag.
(all): Use unifiles rather than charprop.el.
(FORCE): New variable and phony rule.
(${unidir}/charprop.el): Respect FORCE.
(unifiles): New rule.
* src/Makefile.in ($(srcdir)/macuvs.h)
($(lispsource)/international/charprop.el): Add explicit FORCE.
Fixes: debbugs:18489
src/decompress.c (init_zlib_functions): Move the message about zlib
being unavailable from here...
(Fzlib_decompress_region): ...to here.
lisp/url/url-http.el (url-http-create-request): Recheck zlib availability
on windows-nt each time it might be required.
These were already defined in buffer.c, and the duplicate
definitions cause problems on platforms like 'gcc -fno-common'.
Reported by Peter Dyballa in: http://bugs.gnu.org/9927#137
* macfont.m: Fix indentation and import changes from macport
24.3.94.
(macfont_closest_traits_index): New function.
(macfont_closest_traits_index_p): Renamed from
macfont_closest_traits_index.
(macfont_list): Use macfont_closest_traits_index_p.
