sector and realm timestamps to current time. It's not useful, and it
facilitates attacks against the PRNG. This backs out fairland.c
rev. 1.27 and files.c rev. 1.31 and partly backs out files.c
rev. 1.38.
(isok, ef_init, bmaps_intersect, bp_init, player_accept)
(finish_sects, main): Use it.
(bp_neighbors, bp_lbcost, pathcost): Use XYOFFSET(). No
functional change.
xdump:
(gamestr): New member game_upd_disable.
(game_ca): Update accordingly.
(game_ctrl_update): New.
(disa, enab): Use it.
(updates_disabled): Rewrite and move to game.c
(disablefil): Remove.
(fmttime2822) [_WIN32]: %T is not support option for strftime in WIN32
replaced with %H:%M:%S. Replaced %z in with +/-???? format for WIN32
as the default for WIN32 is the text description for timezone.
flawed. Firstly, when player_kill_idle() ran before the player thread
could react to being aborted by update or shutdown, player_kill_idle()
incorrectly diagnosed it as hung. Secondly, terminating hung threads
leaks resources and can leave a stale play_lock behind. It could
perhaps even corrupt game state. It might salvage some scenarios, but
makes others worse. Not worth it.
supports priorities. Update synchronization used to rely on them,
which naturally worked only with LWP (#1504036). With that fixed, no
uses of priorities remained, but a minor bug did: players could starve
out threads with priorities below PP_PLAYER, i.e. delete_lostitems()
and player_kill_idle(). Closes#1458175:
(empth_create): Remove parameter prio. Callers changed. Also gets
rid of misleading comments in pthread.c and ntthread.c.
(PP_MAIN, PP_UPDATE, PP_SHUTDOWN, PP_SCHED, PP_TIMESTAMP, PP_PLAYER)
(PP_ACCEPT, PP_KILLIDLE): Remove.
(empth_init, empth_create) [EMPTH_LWP]: Pass priority 1.
sure the command is reliably aborted on update and shutdown. Before,
redirection output could block while player->command was still null,
letting players delay the update or shutdown indefinitely.
wanted. Unfair to writers, but possible. This lets commands run with
!player->aborted, which can then block on input and thus let players
delay the update or shutdown indefinitely. Avoid by spinning until
the update is done.
threads were runnable. This let players with a sufficiently fast
connection starve out system threads, including the update. Fix:
[EMPTH_LWP] (lwpWakeupSleep): External linkage.
[EMPTH_LWP] (lwpReschedule): Call it.
(update_run): Set it.
Replace incorrect uses of update_pending by update_running, fixing
buggy behavior while the update was trying to gain control:
(sct_do_upd_mob, shp_do_upd_mob, lnd_do_upd_mob, pln_do_upd_mob):
MOB_ACCESS mobility update was skipped.
(telegram_is_new): Fix recognition of new telegrams by timestamp.
(wu): Bulletins got misfiled as production reports.
(shp_nav): Sail path got ignored.
(setrel): Declaration of war failed silently with SLOW_WAR enabled.
Messages got suppressed.
(PR, mpr): Messages got misdirected to bulletins.
(show): New sub-command.
(player_coms): Update its c_form.
(show_updates, fmttime2822): New.
(vers): Show game_days and game_hours.
(upda): Mark obsolete and point to show updates.
(vers): Point to show rather than update.
Rewrite much of info zdone.
