* numeric session ids now restored; LoginActor knows about connection address; corpses are barren unless searched
* session and login id/counter moved under server; function literal definition changed
* corpse channel
* trying to fix docker as per set-env requirement changes; I don't know what I'm doing
The game uses a UDP-based protocol. Unlike TCP, UDP does not guarantee that
packets arrive, or that they arrive in the correct order. For this reason,
the game protocol implements those features using the following:
* All packets have a sequence number that is utilized for reordering
* Important packets are wrapped in a SlottedMetaPacket with a subslot number
* RelatedA packets ae used to request lost packets using the subslot number
* RelatedB packets are used to confirm received SlottedMetaPackets
All of these go both ways, server <-> client. We used to only partially
implement these features: Outgoing packet bundles used SMPs and could be
resent, but not all packets were bundled and there was no logic for requesting
lost packets from the client and there was no packet reordering, which resulted
in dire consequences in the case of packet loss (zoning failures, crashes and many
other odd bugs). This patch addresses all of these issues.
* Packet bundling: Packets are now automatically bundled and sent as
SlottedMetaPackets using a recurring timer. All manual bundling functionality
was removed.
* Packet reordering: Incoming packets, if received out of order, are stashed and
reordered. The maximum wait time for reordering is 20ms.
* Packet requesting: Missing SlottedMetaPackets are requested from the client.
* PacketCoding refactor: Dropped confusing packet container types. Fixes#5.
* Crypto rewrite: PSCrypto is based on a ancient buggy version of cryptopp.
Updating to a current version was not possible because it removed the
MD5-MAC algorithm. For more details, see Md5Mac.scala.
This patch replaces PSCrypto with native Scala code.
* Added two new actors:
* SocketActor: A simple typed UDP socket actor
* MiddlewareActor: The old session pipeline greatly simplified into a
typed actor that does most of the things mentioned above.
* Begun work on a headless client
* Fixed anniversary gun breaking stamina regen
* Resolved a few sentry errors
* object registration adjustments for players and avatars and lockers (especially lockers)
* refactored locker container
* modifications to fields and method names for guid-related files; SpecificNumberSource created
* locker item display; proper item insertion into locker-space and searchability of that locker-space
* proper item removal from locker-space, including swap-items on other insertion tasks
* comments and tests; adjusted avatar/player registrations; allowed for restriction in the SpecificNumberSource; renamed CataloguedInventory to LocallyRegisteredInventory, and made internal object registration work
* accommodations for RequestDestroy, to allow the locker's Clear button to work; modification of expectation for resolving projectiles through ValidObject
