In certain circumstances, like when running a private server through
Hamachi, the shard IP will be set to an address the local machine can't
reach itself from, preventing only the local player from getting past
character selection. This workaround detects local connections and
sends a loopback address for the shard instead of the configured one.
This makes those use cases feasible.
Also reorder the rapid fire check in MobManager::pcAttackNpcs(), so the
output packet validation happens immediately before the buffer is
initialized, for clarity.
Recheck the entry at the current index after we remove one. This isn't
strictly necessary, since the next pass will get it anyway.
Using a vector as opposed to our own realloc()'d array means indexing
beyond the size() is undefined behavior, so it's better to be safe.
This is how it should have been handled anyway. This fixes a (benign)
race condition when the server is killed, as well as gprof builds.
Also updated tdata.
* Fixed Nano stamina not being halved on respawn
* Reverted the default argument to terminate() change because MSVC is
undable to disambiguate the function pointer passed to sigaction()
* Fatal errors during init (like in TableData) can just call exit(1)
directly anyway (missing "OpenFusion: terminated." be damned)
* Switched to a slightly more portable syntax for getting the version
in the Makefile
* We shouldn't join the shard thread in the signal handler because the
thread the signal handler ends up running in is undefined behaviour and
we don't strictly need to join it anyway
Many of these issues were discovered on OpenBSD.
* Gave it a default argument, since we never actually care about it, but
it needs to have it to conform to the signal handler prototype
* Constricted the area locked by activeCrit to only the block that deals
with the connections vector, to lower the chance of a future badly
placed call to terminate() deadlocking the server instead
* Extracted PollFD manipulation and nonblocking socket configuration
into helper functions
* Replaced the connections list with an unordered_map
* Dynamically grow the number of PollFD structures with realloc()
With these changes done, the server's CPU usage is completely diminished
from its old average of ~47% to ~0.07%, with occasional spikes up to ~14%.
* Deleted empty Player.cpp
* Moved the helper functions from the obsolete CNStructs.cpp into
main.cpp and deleted it
* Renamed CombatManager to MobManager, as that will likely become it's
main focus soon
Also changed output buffer in pcAttackNpcs() from dynamically to
statically allocated. This in itself is temporary as I have a better
idea as to how we can allocate buffers with a bit less boilerplate.
