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.
(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.
(schedulefil): New.
(set_dirs, set_paths): Rename. Initialize schedulfil.
(read_schedule): New. Can read several updates, which will be used in
later changesets.
(update_time): Change to array. Will be used in later changesets.
(update_schedule_anchor): New.
(update_init): Initialize it.
(update_get_schedule): New.
(update_init): Call it to initialize update_time[].
(update_sched): Rewrite.
(update_forced, update_wanted): Replace.
(update_reschedule): New.
(main): Call it on SIGHUP to reload the schedule.
(update_trigger, update_force, force, player_coms): Drop force's
capability to schedule updates in the future, because it's not worth
the trouble to implement again. Deities can simply edit the schedule
file to schedule updates. Remove update_force() and
update_trigger()'s parameter.
(upda): Update for new scheduler. Take care to keep output the same
as far as possible, even though it's ugly, to avoid breaking clients.
(update_policy, adj_update, update_times, hourslop, blitz_time):
econfig keys removed.
(update_demand, UPD_DEMAND_NONE, UPD_DEMAND_SCHED, UPD_DEMAND_ASYNC)
(update_demandpolicy, UDP_NORMAL, UDP_TIMES, UDP_NORMAL, UDP_BLITZ)
(UDP_MAX, UDP_DEFAULT, UDDEM_TMCHECK, UDDEM_COMSET, UDDEM_DISABLE)
(UDDEM_MAX, UDDEM_DEFAULT): econfig key and values replaced. Users
changed. wantupd.h is now empty, remove.
(demand_check): External linkage.
(update_policy_check): Now pointless, remove.
(is_daytime_near, min_to_next_daytime, regular_update_time)
(scheduled_update_time, next_scheduled_time, updatetime)
(next_update_time, next_update_check_time): Unused, Remove.
(demand_check, demandupdatecheck): Move call of demand_update_time()
from demand_check(), which controls all demand updates, to
demandupdatecheck(), which controls only unscheduled ones. Fixes
update command not to lie about the next scheduled demand update.
(demandupdatecheck): Check updates_disabled() so that zdone no longer
claims to trigger an update when it can't.
(update_init, update_sched, update_run, update_wait): Don't create a
separate UpdateSched thread, run update_sched() in the Update thread.
Run the update by calling update_run() instead of by signalling its
thread. update_run() replaces update_wait(); it just runs the update
and returns instead of waiting for the signal to update in a loop.
Move initialization of the Update thread's *player to its new thread
entry point.
(update_sem, update_init): Remove update_sem.
(update_thread): New.
(update_init): Initialize it.
(update_forced): New.
(update_trigger, update_force): Wake up update_thread with
update_force set.
(update_sched): Reset it before sleep, test it after sleep so that
schedule checking is only done for scheduled updates, not forced
updates.
(update_sched, update_init): Move sanity test of s_p_etu to
update_init().
(update_trigger): New.
(force, zdon): Use it.
(update_sem, update_force): Internal linkage.
(update_trigger, update_force): Passing a pointer to static storage as
thread argument is racy. Use dynamic allocation.
(update_main): No longer a thread entry point. Remove the parameter.
Remove *player setup. Don't terminate the thread when done.
(update_pending): Move to src/server/update.c.
(update_wait): Call update_main() instead of running it in its own
thread. Set up *player for it.
(update_init): Create the fused update thread instead of the update
wait thread.
resolving #1458175 and #1504036):
(update_lock): New.
(update_shed): Initialize it.
(update_wait, dispatch): Take exclusive update_lock around the update,
shared update_lock around commands. This makes the update block until
all aborted commands terminated and gave up their lock. Remove the
cheesy and unsafe two second wait for commands to finish. It also
makes player threads block before executing commands while the update
is pending, removing the need to fail commands then. So don't.
other. Ensure headers in include/ can be included in any order
(except for econfig-spec.h, which is special). New header types.h to
help avoid inclusion cycles. Sort include directives. Remove some
superflous includes.
Move assignment of hostaddr and hostname from player_new() to
player_accept(). This solves the necessary of adding the socket include
file to prototypes.h for player_new(). The socket include file creates
a namespace conflict for WIN32.
is somewhat stricter.
(is_wday_allowed, is_daytime_allowed, is_daytime_nar,
min_to_next_daytime): New.
(demand_update_time, scheduled_update_time, next_scheduled_time,
update_time, gamehours): Use them to replace kw_parse().
(kw_parse): No longer used, remove.
them. From Marc Olzheim.
Type modifier 'l' was missing in many places, probably rendering the
server useless on 64-bit hosts.
(ef_flush, ef_write, ef_extend, lwpCreate, lwpDestroy): Use conversion
specifier 'p' to print pointers.
(check_market): Fix display of loan amount.
(doland): Fix unescaped '%' (undefined behavior).
(ldump, ndump, pdump, sdump): Don't use flag '0' with conversion
specifier 's' (undefined behavior).
(dump, ldump, lost, ndump, pdump, sdump, empth_create, update_sched):
Cast time_t and pthread_t to long for printing.
(lwpStackCheck, lwpStackCheckUsed, finish_sects): Insert cast to fix
argument type on all platforms.
(prod): Remove extra argument.
(perform_mission, airdamage, retreat_land1, lwpReschedule): Format
string missed arguments.
instead of declaring them all over the place. This uncovered type
errors:
(s_p_etu, adj_update): Defined long, sometimes declared int. Kills
big endian machines where sizeof(long) != sizeof(int). Change to
int.
(set_option, delete_option, optstrset, intset, floatset, doubleset,
longset, optionset, optiondel, worldxset): Change linkage to static.
thread entrypoints:
(lwpSelect, shutdown_sequence): Parameters didn't match thread entry
point prototype.
(lwpEntryPoint): Arguments didn't match thread entry point prototype.
Change linkage of functions without prototype declaration to static
where possible.
Remove some superflous declarations, replace others by suitable
includes.
