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.
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.
(keep_journal): New econfig key.
(player_main): Log player login and logout.
(recvclient): Log player input.
(ef_open_srv, ef_close_srv): Log startup and shutdown.
(update_main): Log update.
Support the common SIGHUP log rotation idiom:
(empth_wait_for_shutdown, empth_wait_for_signal): Rename.
[EMPTH_LWP, EMPTH_POSIX] (empth_init, empth_wait_for_signal): Wait for
SIGHUP as well.
(main) [SIGHUP]: Reopen journal when empth_wait_for_signal() returns
SIGHUP.
(empth_wait_for_shutdown): New.
(main): Use it to wait for shutdown signal, then shut down. Closes
#770492.
(empth_exit): Remove the weird special case for main thread.
Implement empth_wait_for_shutdown() for EMPTH_LWP:
[EMPTH_LWP] (lwpInitSigWait, lwpSigWait, lwpSigWakeup): New.
Declaration of lwpSigWait was accidentally committed in the previous
revision of lwp.h.
[EMPTH_LWP] (lwpInitSystem): New parameter waitset, pass it on to
lwpInitSigWait().
[EMPTH_LWP] (lwpReschedule): Call lwpSigWakeup().
[EMPTH_LWP] (empth_init): Declare signals needed by
empth_wait_for_shutdown().
(empth_wait_for_shutdown): Implement on top of lwpSigWait().
Implement empth_wait_for_shutdown() for EMPTH_POSIX:
[EMPTH_POSIX] (empth_init): Block signals, so that
empth_wait_for_shutdown() can use sigwait() safely.
(empth_wait_for_shutdown): Implement on top of sigwait().
Implement empth_wait_for_shutdown() for EMPTH_W32:
(empth_wait_for_shutdown): Implement on top of loc_BlockMainThread().
(empth_init_signals): New, factored out of start_server(). Call from
empth_init().
(panic): Move to posix.c, internal linkage.
(empth_obj): Add new posix.o
(empth_start, empth_alarm) [EMPTH_POSIX]: Clean up pointless messing
with signal handlers.
(empth_init, empth_wakeup) [EMPTH_POSIX]: Clean up a bit.
compiler command line. Don't bother to conditionalize code in .c
files that are only compiled when their thread package is used.
(_EMPTH_LWP, EMPTH_LWP, _EMPTH_POSIX, EMPTH_POSIX, _EMPTH_WIN32)
(EMPTH_W32): Identifiers beginning with an underscore and an uppercase
letter are reserved for any use. Rename.
complete declaration to src/lib/lwp/lwpint.h.
(lwpQueue): Move to src/lib/lwp/lwpint.h.
(empth_main, empth_flags): New.
(empth_init): Initialize them.
(empth_create, empth_exit): Use them instead of lwpProc members.
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.
