agribusiness. That was done when the occupier abandons the old-owners
capital or it revolts, to prevent players from sacking the same
capital many timers. The server has a much better way to prevent that
since 4.2.7, so this weird hack is no longer useful. Thanks to Pat
Loney for pointing this out.
have SOMAXCONN, but has LISTENMAXCONN. In fact, it has SOMAXCONN, and
LISTENMAXCONN doesn't exist anywhere in /usr/include or the Internet.
Remove the special case.
(empth_t, empth_sem_t): Define as incomplete types in empthread.h,
complete in pthread.c, to avoid exposing implementation details.
(EMPTH_KILLED): Move from empthread.h to pthread.c.
which are obsolete since at least 1997.
(empth_terminate, empth_wakeup) [__ppc__]: Ancient versions of OS X
lacked pthread_kill(). As a work-around, its use was disabled here
for all versions of OS X. The work-around could lead to hangs.
Remove it and drop support for ancient versions of OS X.
(empth_create) [__linux__]: Linux has supported thread attribute
stacksize for ages. Remove the special case.
(_MIT_POSIX_THREADS): Unused, remove.
Add html links for info references. Remove inconsistent periods.
Add missing closing brackets. Change info to information to improve
readability. Improve the readability for range/lrange sentence.
units do not react to a mountain.
(stre): Add an empth_yield() per sector to make the server responsive
to other players as this command is CPU intensive.
SO_REUSEADDR socket option as it is not required for WIN32.
In WIN32, there is no waiting time when a port is closed before
it can be reused so SO_REUSEADDR is not required for WIN32.
Leave the option has a undesirable effect of allowing a second
server instance to start without an error and leaving both
instances running. ALPHA and LINUX do support SO_REUSEADDR.
after every command, other players gets a chance to execute a command.
This prevents denial of service attack that monopolizing the active server
thread by continuing feeding data to the server from a client.
is unsafe! By the time the blocked thread wakes up, that player may
be gone, along with its struct iop *, and io_write() follows a
dangling pointer. Moreover, at most one thread may use empth_select()
on the same file descriptor. Violations of that restriction cause
threads to hang under Windows since ntthread.c rev. 1.15. Make all
output to another player non-blocking for now. Historically, player
threads sent output only to their socket, though their own iop. This
was broken by flash and asynchronous telegram notification a long time
ago.
