empth_sleep() return whether that happened:
[EMPTH_LWP] (lwpWakeupSleep): New, factored out of lwpSelect().
[EMPTH_LWP] (lwpSelect): Use it.
[EMPTH_LWP] (lwpWakeup): New. Call lwpWakeupFd() if sleeping in
lwpSleepFd(), lwpWakeupSleep() if sleeping in lwpSleepUntil().
[EMPTH_LWP] (lwpTerminate, empth_wakeup): Use it rather than
lwpWakeupFd().
[EMPTH_LWP] (lwpWakeupFd): Internal linkage.
[EMPTH_LWP] (lwpSleepUntil): Reset member runtime, so that lwpWakeup()
can test it reliably. Return how sleep woke up.
[EMPTH_LWP] (empth_sleep): Return value of lwpSleepUntil().
[EMPTH_POSIX] (EMPTH_INTR): New.
[EMPTH_POSIX] (empth_wakeup): Set state to it.
[EMPTH_POSIX] (empth_restorectx): Clear state.
[EMPTH_POSIX] (empth_sleep): Don't re-seleep when state is not clear,
i.e. thread was woken up prematurely. Return how sleep woke up.
[EMPTH_W32] (empth_sleep): Implement by waiting on hThreadEvent with a
timeout rather than a straight Sleep(). Return how sleep woke up.
land_unit as well.
(do_unit_move): Add view option for land units using unit_view().
Combine ship and land viewing using the unit_view().
(shp_view): Remove, not used any more, replaced by unit_view().
(journal_reopen): New.
(main): Use it. Fixes failure to obey !keep_journal.
(journal_open): Internal linkage, changed semantics and return value.
Callers changed.
(journal_close): One caller left, inline and remove.
(shutdown_initiate): New.
(shut): Use it. Shutdown in zero minutes no longer cancels the
shutdown, it just works. Use negative argument to cancel. Logging is
less detailed.
(shutdown_sequence): Internal linkage.
(pr_wall): All callers prefix text it with the same header. Move it
into the function.
(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.
type. Make it abstract because that's possible. Change data layout
so that the slots belonging to a sector are together in memory, it's
nicer to the cache.
(bp): The new type. Users changed.
(get_wp): Update accordingly.
(alloc_bp): New.
(update_main, calc_all): Use it. Before, calc_all() allocated 1/7
more than necessary.
(shiprepair, planerepair, landrepair): Use it. Behavioral change:
ship repairs outside harbors and plane repairs by a carrier can use
fewer materials. Before, such repairs consumed each required
commodity as far as available. Now, they consume the same fraction of
the real cost of each commodity, i.e. commodity use is limited by the
most scarce commodity. Neither old nor new behavior make much sense,
but the new code is simpler.
(opt_AUTO_POWER, update_power): New.
(update_main): Implement AUTO_POWER.
(powe): Disable power new when AUTO_POWER is on.
(powe): New power update.
(gen_power): Compute power into buffer passed by caller, make write to
power file optional.
(emp_obj_chr_name): New. Returns a pointer to the characteristics name
for an empobj.
(unit_map): Simplify unit_map() by using get_empobjp() and
emp_obj_chr_name().
(map, cmd_move_map): Switch to EF_SHIP as unit_map does not default
to EF_SHIP for EF_BAD anymore.
