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 |
