|
| Every NetLink for the db server has a unique ''lock_id'', starting from 0. They are used to identify current connections to MapServer in order to send messages.
| | It is documented on [[Dbserver-to-mapserver]] |
| | |
| === DBCLIENT_INITIAL_CONNECT ===
| |
| | |
| optional packint(1) map_protocol
| |
| | |
| If ''map_protocol'' is not present (the body is empty), it is 0. If ''map_protocol'' is not equal to DBSERVER_PROTOCOL_VERSION (currently 20110503) then dbserver will respond with DBSERVER_CLIENT_CMD_FAILED and close the NetLink.
| |
| | |
| Otherwise, dbserver sends these commands back to the MapServer:
| |
| | |
| DBSERVER_TIMEOFFSET:
| |
| bits(32) seconds_since_2000
| |
| float32 time_zone_delta
| |
| | |
| These values are set based on the system clock. ''time_zone_delta'' is the difference between UTC and local time, in hours.
| |
| | |
| DBSERVER_OVERRIDDEN_AUTHBITS
| |
| bits(128) overridden_auth_bits
| |
| | |
| The value of ''overridden_auth_bits'' is set based on OverrideAuthBit lines in servers.cfg.
| |
| | |
| If any DisabledZoneEvents entries are present in servers.cfg, dbserver sends a DBSERVER_DISABLED_ZONE_EVENTS command:
| |
| repeated string event
| |
| | |
| One entry for each DisabledZoneEvents line in servers.cfg
| |
| | |
| If user reactivation is active, dbserver sends a DBSERVER_NOTIFY_REACTIVATION message, with no body.
| |
| | |
| DBSERVER_UPDATE_LOG_LEVELS:
| |
| repeated LOG_LEVELS times:
| |
| packint(1) log_level
| |
| | |
| These are the log levels, as managed by log.h, for all logging types in order from 0 to LOG_LEVELS. They are set in servers.cfg with SetLogLevel lines.
| |
| | |
| DBSERVER_ACCOUNTSERVER_CATALOG:
| |
| autobits catalog_timestamp
| |
| autobits auth_timeout
| |
| string mtx_environment
| |
| string play_span_domain
| |
| string play_span_url_home
| |
| string play_span_url_categoryview
| |
| string play_span_url_itemview
| |
| string play_span_url_showcart
| |
| string play_span_url_addtocart

| string play_span_url_updatetovip
| |
| string coh_url_newfeatures
| |
| string coh_url_newfeaturesupdate
| |
| autobits play_span_store_flags
| |
| | |
| These appear to be values set in account_server.cfg. Most of them are URLs.
| |
| | |
| === DBCLIENT_READY ===
| |
| | |
| This message is understood by dbserver, but does not appear to be sent by mapserver; it is suspected to be historical debris.
| |
| | |
| === DBCLIENT_REGISTER ===
| |
| | |
| packint(1) map_id
| |
| packint(1) local_ip
| |
| packint(1) remote_ip
| |
| packint(1) udp_port
| |
| packint(1) tcp_port
| |
| packint(1) static_link
| |
| packint(1) cookie
| |
| string patch_version
| |
| optional string map_name
| |
| | |
| A MapServer sends this message when it starts up, immediately after DBCLIENT_INITIAL_CONNECT.
| |
| | |
| static_link is set based on the command line of the MapServer
| |
| | |
| map_id is a signed int, set on the command line of the MapServer. Negative values mean that a map_name field will be sent and edit mode will be used.
| |
| | |
| If map_id is non-negative, then dbserver selects the container for this mapserver based on map_id, and closes the link if the map_id is not known. Otherwise, dbserver selects the container based on map_name, and enables edit mode on this container. If static_link is set, then dbserver searches for a map with this name. If static_link is not set, or no map of this name is found, then a new map container is created and populated with the data in the map_name field.
| |
| | |
| udp_port and tcp_port are the ports on which the MapServer will listen for game clients, and are set on the command line.
| |
| | |
| cookie is set on the command line of the MapServer, and sent as-is. If the cookie is non-zero, then dbserver will validate that it matches the cookie matches the container referenced by map_id, and will close the link if it does not match. This is used to ensure the MapServer is the one this dbserver wanted to spawn, and not from a previous instance of dbserver.
| |
| | |
| local_ip and remote_ip are sent by the mapserver, based on the result of gethostbyname(NULL). They will use the first two results from this function. If one of those results is an rfc1918 address, or 127.0.0.1 (none of the other loopback addresses are recognised as "local"), then it will be local_ip; otherwise local_ip will be the first result from gethostbyname() and remote_ip will be the second.
| |
| | |
| The map container in the dbserver will have its link set to the link which sent this message, and will be marked starting and active. dbserver will respond to the MapServer with DBSERVER_CONTAINERS, sending the container for map_id followed by the containers for all static maps.
| |
| | |
| === DBCLIENT_REGISTER_CONTAINER_SERVER ===
| |
| | |
| packint(1) list_id
| |
| | |
| The client attempts to claim ownership of the DbList identified by list_id. This is used by RaidServer to register itself with dbserver. Only one link may own a DbList at a time. If another link has claimed the DbList, then this one is marked as waiting for it. If the owner of the DbList is disconnected, then a link which is waiting for it will become the owner.
| |
| | |
| When a link becomes the owner of a DbList, then dbserver sends it a DBSERVER_CONTAINER_SERVER_ACK:
| |
| packint(1) list_id
| |
| packint(1) max_session_id
| |
| | |
| Owning a DbList affects the handling of DBCLIENT_CONTAINER_RELAY and DBCLIENT_REGISTER_CONTAINER_SERVER_NOTIFY messages.
| |
| | |
| === DBCLIENT_REGISTER_CONTAINER_SERVER_NOTIFY ===
| |
| packint(1) notify_mask
| |
| | |
| All DbLists owned by this link have their notify mask set to notify_mask.
| |
| | |
| notify_mask is a bitmask, where each bit corresponds to a ContainerType value. For each bit set, when a notification for that DbList is available, a DBSERVER_CONTAINER_SERVER_NOTIFY will be sent:
| |
| packint(1) list_id
| |
| packint(1) container_id
| |
| packint(1) member_id
| |
| bits(1) is_added
| |
| | |
| Notifications are only sent for the addition of Ents (player characters loading onto a map), deletion of containers, and for adding and removing group members. When an Ent is added, an add notification is sent for all groups that Ent is currently a member of.
| |
| | |
| is_added is 1 if a thing is being added, and 0 if a thing is being removed.
| |
| | |
| container_id is the id of the container being updated - either the group where members are being added or removed, or the container being deleted.
| |
| | |
| member_id is 0 if the operation is the removal of a group (supergroup deletion, etc), or the member ID if the operation is adding or removing a member from a group.
| |
| | |
| === DBCLIENT_READY_FOR_PLAYERS ===
| |
| packint(1) map_id
| |
| | |
| This message is sent by MapServer when it has finished settup in the map. It marks the MapCon as not starting. If the MapCon has been marked for shutdown in the dbserver, then the dbserver will respond with an empty DBSERVER_TEAM_LEFT_MISSION message.
| |
| | |
| === DBCLIENT_CONTAINER_INFO ===
| |
| | |
| This message has no body. dbserver will respond with DBSERVER_CONTAINER_INFO:
| |
| packint(1) count
| |
| string dbserver_status
| |
| repeated count-1 times:
| |
| string container_status
| |
| | |
| dbserver_status will be a string like "DbServer started on %s, Up %d hours, %d minutes"
| |
| | |
| container_status will be a string like "0040 Ent (1)", giving the number of allocated containers in the each DbList, and its name and ContainerType value.
| |
| | |
| === DBCLIENT_REQ_CONTAINERS ===
| |
| packint(1) user_data
| |
| packint(1) list_id
| |
| packint(1) cmd
| |
| packint(1) count
| |
| repeated count times:
| |
| packint(1) container_id
| |
| | |
| dbserver will respond to this message with DBSERVER_CONTAINERS, with some containers selected from DbList ''list_id''. ''user_data'' is returned in the DBSERVER_CONTAINERS response.
| |
| | |
| If cmd is CONTAINER_CMD_LOAD_ALL, count is ignored and all containers in the list are selected. Otherwise, container_id values are sent in the message, and those containers are selected.
| |
| | |
| Depending on the command selected, three other operations might be performed on this list:
| |
| * With CONTAINER_CMD_LOCK_AND_LOAD, CONTAINER_CMD_LOAD_ALL, CONTAINER_CMD_TEMPLOAD, or CONTAINER_CMD_TEMPLOAD_OFFLINE the containers will be loaded if necessary. Otherwise, containers that are not loaded will return an error code of CONTAINER_ERR_DOESNT_EXIST for that container.
| |
| * With CONTAINER_CMD_LOCK or CONTAINER_CMD_LOCK_AND_LOAD the containers will be locked to this link. Any container which is already locked by another link will return an error code of CONTAINER_ERR_ALREADY_LOCKED for that container.
| |
| * With CONTAINER_CMD_TEMPLOAD or CONTAINER_CMD_TEMPLOAD_OFFLINE any containers that have to be loaded for this message will be unloaded after it is finished.
| |
| * With CONTAINER_CMD_TEMPLOAD_OFFLINE the special handling for offline players (???) is used.
| |
| | |
| === DBCLIENT_SET_CONTAINERS ===
| |
| | |
| packint(1) list_id
| |
| packint(1) cmd
| |
| packint(1) callback_id
| |
| packint(1) count
| |
| repeated count times:
| |
| packint(1) container_id
| |
| packint(1) notdiff
| |
| packint(1) debugdiff
| |
| string str
| |
| optional string debugdiff_str
| |
| | |
| ''debugdiff_str'' is only sent when debugdiff is not 0, otherwise it is skipped
| |
| | |
| dbserver stores the containers, and responds with DBSERVER_CONTAINER_ACK to most messages:
| |
| packint(1) list_id
| |
| packint(1) callback_id
| |
| packint(1) count
| |
| repeated count times:
| |
| packint(1) ack_id
| |
| | |
| The ''ack_id'' values will be the ''container_id'' values that were updated.
| |
| | |
| One DBSERVER_CONTAINER_ACK response is sent after '''every''' update is applied, containing all acks so far (this appears to be a bug, and not used for anything). Acks are used by MapServer to return the container_id when creating containers, and otherwise ignored.
| |
| | |
| The exception to this are:
| |
| * when list_id is the AutoCommands list, in which case dbserver will instead respond by broadcasting a DBSERVER_CONTAINERS message to all active MapServers with the new container value
| |
| * when the container is a GroupCon type, and ''cmd'' is not CONTAINER_CMD_UNLOCK_NOMODIFY, in which case dbserver will instead respond by broadcasting a DBSERVER_CONTAINERS message to all interested links:
| |
| ** MapServers that are running members of a MapGroup
| |
| ** MapServers that have connected Ents for other groups
| |
| ** the MapServer for a supergroup base
| |
| ** the statserver for a statserver group
| |
| ** the link that sent the DBCLIENT_SET_CONTAINERS message)
| |
| | |
| In these cases, no DBSERVER_CONTAINER_ACK messages are sent.
| |
| | |
| Possible values for ''cmd'' are:
| |
| * CONTAINER_CMD_CREATE, in which case ''id'' must be -1 and the container will be created.
| |
| * CONTAINER_CMD_CREATE_MODIFY, in which case ''id'' may be -1 and the container will be created if no container with this id exists.
| |
| * CONTAINER_CMD_DELETE, which will mark the container for deletion. ''str'' is ignored.
| |
| * CONTAINER_CMD_UNLOCK, which will apply updates and then unlock the container if this link has it locked.
| |
| * CONTAINER_CMD_UNLOCK_NOMODIFY, which will unlocked the container if this link has it locked, and not attempt to update the container. ''str'' is ignored
| |
| * CONTAINER_CMD_TEMPLOAD, which will load the container before updating it, and unload it after updating it, regardless of whether it was already loaded.
| |
| | |
| All other values of ''cmd'' will apply the update to an existing container.
| |
| | |
| If an error occurs, dbserver will abandon processing of the rest of the message, and respond with DBSERVER_CLIENT_CMD_FAILED:
| |
| packint(1) fail_code
| |
| string str
| |
| | |
| This occurs in the following scenarios:
| |
| * ''id'' is -1 for commands other than CREATE and CREATE_MODIFY, or ''id'' being any value other than -1 for CREATE, will return CONTAINER_ERR_DOESNT_EXIST
| |
| * Parse errors for the container in ''str'' will return CONTAINER_ERR_CANT_COMPLETE_SERIOUS
| |
| * An attempt to create an Ent on an account without free character slots will return CONTAINER_ERR_CANT_COMPLETE
| |
| * An attempt to create an Ent where the character name cannot be parsed will return CONTAINER_ERR_CANT_COMPLETE
| |
| * For DbList other than maps, a container that exists must not be locked to a link other than this one, or it will return CONTAINER_ERR_ALREADY_LOCKED
| |
| * For DbList other than maps, and commands other than CREATE_MODIFY, the container must be locked or it will return CONTAINER_ERR_NOT_LOCKED
| |
| * If the container does not exist for whatever reason (after processing creation), it will return CONTAINER_ERR_DOESNT_EXIST
| |
| | |
| ==== Applying container updates ====
| |
| | |
| ''str'' will be treated as a diff if ''notdiff'' is 0, or as a full copy of the container if ''notdiff'' is 1.
| |
| | |
| If the container does not have a template, then the string supplied always treated as a complete replacement, and the content of the container is simply set to this value, then special column processing is run.
| |
| | |
| If the container has a template, and ''notdiff'' is 1, then a diff will be computed from the current value of the template to the string supplied, and then processing will continue as if a diff had been sent.
| |
| | |
| If the container has a template, then the string will be parsed into a line list, and then merged into the current line list. Next, special column processing is run. The computed updates are then added to the queue of sql writes, and if the container has an update callback, it is called (this is probably a bug: it will be called twice).
| |
| | |
| Special columns processing begins by calling the update callback. It then runs through a list of commands, which identify fields in the line list by name. The values of these fields will be written into some address inside the DbContainer struct, as identified by the command. In the particular case of CMD_MEMBER, special tracking is done of memberships, which may result in sending notifications to servers that requested them with DBCLIENT_REGISTER_CONTAINER_SERVER_NOTIFY.
| |
| | |
| ==== Special hackery ====
| |
| | |
| If the command is CREATE and the DbList is Ents (creating a player), then the player name will be uniquified (by appending or incrementing a number).
| |
| | |
| If the DbList is maps, and there is a map name in ''str'', and a container with that name exists, then ''id'' is ignored and the container with that name is updated instead.
| |
| | |
| If the DbList is Ents and the container exists, and ''str'' contains a MapId field, then it must be equal to the map_id in the Ent or the server will assert (!!!).
| |
| | |
| If ''debugdiff'' is set, then the ''debugdiff_str'' field must be precisely equal to the observed diff to the container after the operation, or the server will assert (!!!).
| |
| | |
| If the command is CREATE and the DbList is Teamups, Supergroups, Taskforces, or Leagues, and the DbList is being stored in sql, then an sql barrier will be generated (all workers will synchronise).
| |
| | |
| If the DbList is maps, and the container is not being deleted, then dbserver will ask a launcher to start a MapServer if it does not have a link from a MapServer on this container.
| |
| | |
| === DBCLIENT_CONTAINER_RELAY ===
| |
| | |
| packint(1) cmd
| |
| packint(1) list_id
| |
| packint(1) cid
| |
| packint(1) user_cmd
| |
| packint(1) user_data
| |
| ... more data that dbserver does not parse
| |
| | |
| If ''list_id'' is not recognised, or no server has that DbList locked, then dbserver will respond with DBSERVER_CONTAINER_RECEIPT:
| |
| packint(1) cmd
| |
| packint(1) list_id
| |
| packint(1) cid
| |
| packint(1) user_cmd
| |
| packint(1) user_data
| |
| packint(1) error_code
| |
| string error_msg
| |
| | |
| where ''error_code'' will be CONTAINER_ERR_CANT_COMPLETE.
| |
| | |
| Otherwise, dbserver will forward the message to the server which has locked that DbList, as DBSERVER_CONTAINER_RELAY:
| |
| packint(1) cmd
| |
| packint(1) list_id
| |
| packint(1) cid
| |
| packint(1) user_cmd
| |
| packint(1) user_data
| |
| packint(1) lock_id
| |
| ... everything else from the DBCLIENT_CONTAINER_RELAY is copied here
| |
| | |
| This is used for MapServer to send messages to RaidServer.
| |
| | |
| === DBCLIENT_CONTAINER_RECEIPT ===
| |
| | |
| packint(1) lock_id
| |
| ... more data that dbserver does not parse
| |
| | |
| dbserver finds the MapServer connection corresponding to ''lock_id'' and proxies the message to that MapServer as DBSERVER_CONTAINER_RECEIPT:
| |
| ... all the data from the input message
| |
| | |
| This is used by RaidServer to acknowledge messages from MapServer.
| |
| | |
| === DBCLIENT_CONTAINER_REFLECT ===
| |
| packint(1) list_id
| |
| packint(1) cmd
| |
| packint(1) target_count
| |
| repeated target_count times:
| |
| packint(1) target_list
| |
| packint(1) target_cid
| |
| packint(1) target_dbid
| |
| packint(1) del
| |
| packint(1) count
| |
| repeated count times:
| |
| packint(1) id
| |
| optionally repeated count times:
| |
| string data
| |
| | |
| ''data'' is present only when ''cmd'' is not CONTAINER_CMD_DELETE
| |
| | |
| If ''cmd'' is CONTAINER_CMD_CREATE_MODIFY, then dbserver will update each container ''id'' with the corresponding ''data'', which is a full copy of the new container value. If ''cmd'' is CONTAINER_CMD_DELETE, then dbserver will delete each container ''id''. No locking is checked for these updates.
| |
| | |
| dbserver now assembles a list of MapServers that these containers will be reflected to. The list is composed by going through the target block, and for each one:
| |
| * target_list is a list_id, target_cid is a container ID in that list
| |
| * If this target is a group container, and it is loaded, then the current MapServer for every loaded and connected member of that group is included
| |
| * If this target is an Ent, then its current MapServer is included
| |
| * If target_list is CONTAINER_MAPS and target_cid is -1, every MapServer is included
| |
| * If this target is a map, then its current MapServer is included
| |
| * If target_list is REFLECT_LOCKID then target_cid is a lock_id, not a container id, and the relevant MapServer is included
| |
| | |
| For each identified MapServer, dbserver sends it a DBSERVER_CONTAINER_REFLECT, with the same format as the input packet. The target list is changed to be the actual targets, discarding anything that could not be resolved to a MapServer.
| |
| | |
| === DBCLIENT_REQ_CONTAINER_STATUS ===
| |
| packint(1) user_data
| |
| packint(1) list_id
| |
| packint(1) count
| |
| repeated count times:
| |
| packint(1) id
| |
| | |
| If ''id'' is -1 then it means all '''active''' containers. If it is -2 then it means all containers. The concept of '''active''' means something different for different container types. Notably, the map for a connected MapServer, and an Ent that is connected to a MapServer, will both be '''active'''.
| |
| | |
| dbserver responds with DBSERVER_CONTAINER_STATUS:
| |
| packint(1) user_data
| |
| packint(1) list_id
| |
| packint(1) count
| |
| repeated count times:
| |
| packint(1) exists
| |
| string status
| |
| where ''status'' will be either a DbList-specific status string, or "%3d Active %d locked %d", populated with container id, '''active''' status, and '''locked''' status.
| |
| | |
| === DBCLIENT_REQUEST_MAP_XFER ===
| |
| packint(1) map_id
| |
| string mapinfo
| |
| packint(1) find_best_map
| |
| packint(1) entity_id
| |
| bits(1) have_extra_data
| |
| optional autobits extra_crc
| |
| optional zipped extra_data
| |
| | |
| The ''extra_crc'' and ''extra_data'' fields are present only if ''have_extra_data'' is not 0. If this happens, dbserver will respond with an error. This appears to be a removed feature.
| |
| | |
| If ''mapinfo'' is not empty, then it identifies an instanced map. Otherwise, map_id identifies a specific map.
| |
| | |
| dbserver might override map_id to a different value in some scenarios (relating to Praetorian progression).
| |
| | |
| If ''find_best_map'' is 1, then dbserver will look for a clone of the map and select one based on the number of players currently on it.
| |
| | |
| If the map is instanced or static, a MapServer will be started for it.
| |
| | |
| The entity ''entity_id'' will be added to the list of entities waiting for this map, and when that MapServer is ready (possibly immediately), dbserver will send DBSERVER_MAP_XFER_READY to the MapServer which send the transfer request:
| |
| packint(1) entity_id
| |
| packint(1) new_map_id
| |
| | |
| === DBCLIENT_MAP_XFER ===
| |
| packint(1) map_id
| |
| packint(1) count
| |
| repeated count times:
| |
| packint(1) entity_id
| |
| | |
| Each entity in the list is processed separately.
| |
| | |
| dbserver might override map_id to a different value in some scenarios (relating to Praetorian progression).
| |
| | |
| If the map_id is the one where the entity is currently present, then dbserver responds with DBSERVER_MAP_XFER_FAIL:
| |
| packint(1) entity_id
| |
| string error_message
| |
| | |
| Otherwise, the entity container is unlocked, as the originated MapServer is giving up ownership of this entity, and the map transfer process begins.
| |
| | |
| The entity container is updated with "MapId" set to the map id, and if the map is static, then also "StaticMapId" is set to the map id.
| |
| | |
| The entity is then locked to the MapServer for the new map id, and a DBSERVER_CONTAINERS is sent to that MapServer with the entity container.
| |
| | |
| Notifications are sent for the entity.
| |
| | |
| If the account for this entity has a loyalty status, then DBSERVER_ACCOUNTSERVER_LOYALTY is sent to the new MapServer:
| |
| autobits entity_id
| |
| bits(128) loyalty
| |
| | |
| === DBCLIENT_CONTAINER_ACK ===
| |
| packint(1) list_id
| |
| packint(1) count
| |
| repeated count times:
| |
| packint(1) id
| |
| packint(1) cookie
| |
| | |
| If ''list_id'' is not CONTAINER_ENTS, the dbserver will treat it as an EntCon type anyway and probably crash (!!!).
| |
| | |
| MapServer only sends this message in response to DBSERVER_CONTAINERS for entities.
| |
| | |
| If cookie is 0, the entity will be deleted. If cookie is 1, the entity will be unloaded.
| |
| | |
| If this is part of a map transfer flow, then dbserver will send a DBSERVER_MAP_XFER_OK to the MapServer. If this is part of a login flow, then dbserver will send DBGAMESERVER_MAP_CONNECT to the game client (possibly via QueueServer). Either way, the message will contain:
| |
| packint(1) entity_id
| |
| packint(1) map_id
| |
| packint(1) ip
| |
| packint(1) ip
| |
| packint(1) udp_port
| |
| packint(1) tcp_port
| |
| packint(1) cookie
| |
| | |
| where ''ip'' is the same both times. ''ip'', ''udp_port'', and ''tcp_port'' are the connection information for the game client to connect to the new MapServer. ''cookie'' is copied from the input message.
| |
| | |
| After this, the entity is marked as '''active''', and its '''logging in''' status is cleared.
| |
| | |
| === DBCLIENT_TEST_MAP_XFER ===
| |
| packint(1) list_id // must be CONTAINER_ENTS
| |
| packint(1) map_id
| |
| packint(1) count // not used
| |
| packint(1) entity_id
| |
| | |
| dbserver sends DBSERVER_TEST_MAP_XFER to the MapServer where the entity is currently located, with a body identical to the message received.

| |
| | |
| dbserver finds the map ''map_id'', and marks it as '''running'''.
| |
| | |
| If this map is not static, then dbserver continues as if ''count'' is 0 (no doors are sent), regardless of the data sent.
| |
| | |
| If the map has a base map, then that map is used instead for the remained of this message.
| |
| | |
| If door info was sent, each one is parsed in turn. dbserver scans existing doors to see if any are in approximately the same location. If none are found, then this door is added to the door containers. Any door containers that are not included in this list are deleted.
| |
| | |
| If any changes were made to door containers, then every eligible MapServer will be sent the door list; otherwise, only the MapServer which sent this request will be updated (if eligible). A MapServer is eligible for a door update if its map is static, or a supergroup base. A door list is sent in a DBSERVER_SEND_DOORS message:
| |
| packint(1) count
| |
| zipped data
| |
| where data is a zipped copy of all the door containers in text format.
| |
| | |

| |
| | |
| ==== add mode ====
| |
| | |
| If ''add'' is not 0, then dbserver will attempt to add all members to the group.
| |
| | |
| If the group container is locked by a different link, or if ''autolock'' is set and the container is locked by this link, then dbserver will respond with DBSERVER_CLIENT_CMD_FAILED, error code CONTAINER_ERR_ALREADY_LOCKED.
| |
| | |
| If ''autolock'' is set and ''update'' is not the empty string, dbserver will respond with DBSERVER_CLIENT_CMD_FAILED, error code CONTAINER_ERR_NOT_LOCKED.
| |
| | |
| Otherwise, the change will be applied.
| |
| | |
| When an add operation is applied:
| |
| * If ''update'' is not the empty string, then it is applied to the container. If ''notdiff'' is set then it replaces the container, otherwise it is applied as a diff.
| |
| * All members are added to the container (which must be a group. bug: dbserver will break if it is not).
| |
| * If ''autolock'' is set then the group will be locked
| |
| * If the group is locked then dbserver will respond with DBSERVER_CONTAINERS, containing the new value of the group.
| |
| * If the group is not locked (which means this is adding members without updating the container), then dbserver will instead broadcast the container in the same way as DBCLIENT_SET_CONTAINERS does.
| |
| | |
| ==== remove mode ====
| |
| | |
| If ''add'' is 0, then dbserver will attempt to remove all members from the group.
| |
| | |
| If ''autolock'' is set and the group is not locked, dbserver will respond with DBSERVER_CLIENT_CMD_FAILED, error code CONTAINER_ERR_NOT_LOCKED.
| |
| | |
| If the group is locked by a different link, dbserver will respond with DBSERVER_CLIENT_CMD_FAILED, error code CONTAINER_ERR_ALREADY_LOCKED.
| |
| | |
| Otherwise, the change will be applied.
| |
| | |
| When a remove operation is applied:
| |
| * If ''update'' is not the empty string, then it is applied to the container. If ''notdiff'' is set then it replaces the container, otherwise it is applied as a diff.
| |
| * All members are removed from the container (which must be a group. bug: dbserver will break if it is not).
| |
| * If ''autolock'' is set, then the group is unlocked
| |
| * If the group is locked then dbserver will respond with DBSERVER_CONTAINERS, containing the new value of the group.
| |
| * If the group is not locked (which happens if ''autolock'' is set), then dbserver will instead broadcast the container in the same way as DBCLIENT_SET_CONTAINERS does.

| | |
| If ''logout_login'' is 2 and the queue server is in use, then the entity's account name is added to the auto-login list.
| |
| | |
| If the entity is in the queue, then it is unlocked and dbserver does nothing.
| |
| | |
| If ''logout'' is 0 or ''logout_login'' is 2 then the account will not be logged out.
| |
| | |
| Otherwise:
| |
| * The entity container is backed up.
| |
| * If ''logout'' is not 0 or ''logout_login'' is not 2 then account logout is sent:
| |
| ** dbserver sends ACCOUNT_CLIENT_LOGOUT_ACCOUNT to accountserver
| |
| ** dbserver sends AS_QUIT_GAME to authserver, with reason set to 4
| |
| * The player is unloaded:
| |
| ** dbserver sends DBSERVER_REMOVE_FROM_QUEUE to turnstileserver, with remove_from_group set to 1
| |
| ** If the entity is part of a Teamup, then they are removed from it.
| |
| ** If the entity is part of a League, then they are removed from it, and statserver is sent DBSERVER_SEND_STATSERVER_CMD, with command set to "statserver_league_quit %d 0 0" % entity_id
| |

| |
| | |
| For each ''id'' in ''list_id'', msg is broadcast to that container. If ''id'' is -1, then all containers in that DbList are broadcast to.
| |
| | |
| For each container being broadcast to:
| |
| | |
| If ''list_id'' is a group DbList, then all entities in the group are selected. If it is a Supergroup, and it has a base, then the mapserver for that base is also selected. If it is a statserver group, then statserver is also selected.
| |
| | |
| If ''list_id'' is a MapGroup, all mapservers for that group are selected.
| |
| | |
| DBSERVER_BROADCAST_MSG is sent to all selected links, with the same parameters as the original message. However, instead of the original list of ids, it will be either the member list of the group (if ''list_id'' is a group), or the entity (if ''list_id'' is CONTAINER_ENTS), or empty for all other DbLists.

| |
| | |
| If any of the containers ''id'' in ''list_id'' are not loaded, then an SQL query will be run to get the Name field of every container. Otherwise, the response will be sent from loaded containers. In both cases the response should be the same.
| |
| | |
| dbserver responds with DBSERVER_SEND_GROUP_NAMES:
| |
| packint(1) list_id
| |
| packint(1) count
| |
| repeated count times:

| packint(1) search_offline_ents
| |
| | |
| If ''list_id'' is CONTAINER_MAPS, then ''value'' is interpreted as an integer and the map with this ID is selected.
| |
| | |
| For all other values of ''list_id'', ''element'' is a field name and ''value'' is an exact value to search for. A container with that value will be selected. The value is a string, unless the field is ContainerId, when it will be an integer.
| |
| | |
| If ''online_only'' is set and either:
| |
| * ''element'' is ContainerId
| |
| * ''element'' is Name and the DbList is entities or a group
| |
| then only loaded containers will be searched.
| |
| | |
| If ''element'' is Name, ''list_id'' is CONTAINER_ENTS, and a container has not yet been found, then special handling of offline players is performed (???).
| |
| | |
| dbserver responds with DBSERVER_CONTAINER_ID:
| |
| packint(1) list_id
| |
| packint(1) id
| |
| packint(1) map_id
| |
| where ''id'' will be -1 if no container was found, and ''map_id'' will be -1 unless the container is an active entity, in which case it will be the id of that entity's current map.
| |
| | |
| === DBCLIENT_SHUTDOWN ===
| |
| string msg
| |
| | |
| When this message is received, the dbserver will shutdown.
| |
| | |
| The following steps will occur:
| |
| * All backups are flushed.
| |
| * All mapservers (other than the one used by the client from which this command was sent) are sent DBSERVER_SHUTDOWN and turnstileserver is sent DBSERVER_TS_CRASHEDMAP for each non-static map where mission_info starts with the letter 'E'.
| |
| * dbserver waits for 60 seconds, or until all non-edit-mode mapservers are inactive.
| |
| * The same procedure is run for the mapserver used by the client from which this command was sent.
| |
| * All pending SQL commands are flushed, and dbserver waits for them to finish.
| |
| * dbserver attempts to shut down the logging thread, waiting up to 8 minutes
| |
| * The dbserver process exits
| |
| | |
| The DBSERVER_SHUTDOWN message sent to mapservers will be:
| |
| packint(1) terminal
| |
| string msg
| |
| where ''terminal'' is 1 and ''msg'' is the string passed in the request.
| |
| | |
| === DBCLIENT_WHO ===
| |
| string cmd
| |
| | |
| The rest of the request depends on the value of ''cmd''. In all cases, the response is DBSERVER_WHO:

| where the contents of the message is a string intended for display to a user.
| |
| | |
| ==== serverwho ====
| |
| packint(1) map_id
| |
| | |
| If map_id is negative, dbserver reports on the number of zone (static), edit mode, and mission maps, and sums the rest of the stats for all of them. Otherwise, dbserver reports on the single map selected.
| |
| | |
| dbserver reports on the number of players playing and connecting, the number of entities, and the number of monsters.
| |
| | |
| ==== who ====
| |

dbserver listens on several ports, each one providing a different service. Most services correspond to another server which will connect. All of these services use the common Network protocol, in TCP-only mode.
account
AccountServer connects to this service. It deals primarily with the ShardAccount container, with auth_id being the container ID for this DbList.
It can receive the following commands:
ACCOUNT_SVR_CONNECT
This message has no body. If an AccountServer is already connected, dbserver will respond by closing the link. Otherwise, it will respond with DBSERVER_ACCOUNT_PROTOCOL_VERSION:
autobits protocol_version
string shard_name
autobits count
repeated count times:
autobits auth_id
string auth_name
protocol_version will be DBSERVER_ACCOUNT_PROTOCOL_VERSION, currently 20070925.
dbserver will send the complete list of names and container IDs for all ShardAccount containers.
If IsLoggingMaster is set in server_cfg, dbserver will also send a ACCOUNT_CLIENT_UPDATE_LOG_LEVELS message:
repeated LOG_LEVELS times:
packint(1) log_level
These are the log levels, as managed by log.h, for all logging types in order from 0 to LOG_LEVELS. They are set in servers.cfg with SetLogLevel lines.
ACCOUNT_SVR_RELAY_CMD
autobits message_dbid
optional autobits auth_id
string cmd
auth_id is sent only if message_dbid is 0.
If message_dbid is not 0, then it is the container ID of an Ent, and dbserver will send a DBSERVER_RELAY_CMD to the MapServer where that Ent is connected:
string relay_cmd
where relay_cmd will be:
cmdrelay_dbid %d 0
conprint "%s"
filled in with message_dbid and cmd.
If auth_id is not 0, then it is the auth_id of a player, which will be used to find the link that game client has with the dbserver. If one exists, then dbserver will send it a DBGAMESERVER_ACCOUNTSERVER_UNAVAILABLE:
string cmd
with cmd unchanged.
ACCOUNT_SVR_CHARCOUNT_REQUEST
autobits auth_id
bits(1) vip
The vip flag will be applied to the ShardAccount auth_id, doing an SQL update if necessary.
Some SQL queries will be run to get the current character count, and when they are complete, dbserver will respond with a ACCOUNT_CLIENT_CHARCOUNT_REPLY:
autobits auth_id
autobits unlocked_used_count
autobits total_char_count
autobits bonus_slots
autobits server_max_count
autobits vip_only_server
ACCOUNT_SVR_CHARCOUNT_REPLY
autobits auth_id
autobits shards
repeated shards times:
string shard_name
autobits unlocked_used
autobits total_used
autobits account_extra
autobits server_max
autobits vip_only_server
If shards is 0 then instead the packet will contain:
autobits auth_id
autobits shards
string error_msg
dbserver finds the game client connection corresponding to auth_id and sends it DBGAMESERVER_ACCOUNTSERVER_CHARCOUNT, which is identical to the message received, except the auth_id is not included.
ACCOUNT_SVR_SLOTCOUNT_REQUEST
autobits auth_id
dbserver replies with ACCOUNT_CLIENT_SLOTCOUNT_REPLY:
autobits auth_id
autobits slot_count
Taking slot_count from the ShardAccount container for auth_id
ACCOUNT_SVR_PRODUCT_CATALOG_UPDATE
autobits timestamp
autobits auth_timeout

dbserver will send DBSERVER_ACCOUNTSERVER_CATALOG to every map server, proxying the contents of the packet.
dbserver will send DBGAMESERVER_ACCOUNTSERVER_CATALOG to every connected game client, proxying the contents of the packet.
ACCOUNT_SVR_CLIENTAUTH
autobits auth_id
autobits timestamp
string playspan_digest
dbserver finds the game client connection corresponding to auth_id and proxies this message as DBGAMESERVER_ACCOUNTSERVER_CLIENTAUTH, excluding the auth_id field.
ACCOUNT_SVR_PLAYNC_AUTH_KEY
autobits auth_id
autobits request_key
string plaync_auth_key
dbserver finds the game client link for this auth_id and proxies this message as DBGAMESERVER_ACCOUNTSERVER_PLAYNC_AUTH_KEY, excluding the auth_id.
ACCOUNT_SVR_SHARDXFER
OrderId order_id
autobits step
Depending on the value of step, the layout of the rest of the packet changes. Each of these messages is a step in the process of transferring a player character from one dbserver to another. dbserver will respond with ACCOUNT_CLIENT_SHARDXFER, which begins with the same two fields:
OrderId order_id
autobits step
The rest of the messages are described below, for each possible value of step.
When step is SHARDXFER_VALIDATE_SRC:
autobits ent_id
dbserver responds with:
bits(1) exists
where exists is 1 if the ent_id is a valid Ent and 0 if it does not exist.
When step is SHARDXFER_VALIDATE_DST:
autobits auth_id
bits(1) vip
dbserver responds with:
autobits unlocked_used_count
autobits total_used_count
autobits account_max_slots
autobits server_max_slots
autobits vip_only_server
When step is SHARDXFER_FULFILL_COPY_SRC:
autobits ent_id
autobits type
string visitor_data_packet
then dbserver will send DBSERVER_RELAY_CMD to the MapServer for this Ent (forcibly loading them to a MapServer if the player is offline) with:
cmdrelay_dbid %d
shardxfer_init %s %d %d %s
populated with ent_id, order_id, type, home_shard, visitor_data_packet
where home_shard is the shard_id of this dbserver in turnstile_server.cfg.
If type is XFER_TYPE_VISITOR_OUTBOUND or XFER_TYPE_VISITOR_BACK then visitor_data_packet will be suffixed by a semicolon and the name of this shard from servers.cfg.
If ent_id is not a loaded Ent, and type is XFER_TYPE_PAID, then dbserver runs SQL queries to load the Ent and continues. For all other values of type, it returns an error to AccountServer.
When step is SHARDXFER_FULFILL_COPY_DST:
string container_txt
then dbserver will run an SQL query to check the Ent table for rows where AccSvrLock is order_id (or in development mode, where AccSvrLock is kOrderIdInvalid - this probably breaks things). If that row exists, then the ID of that Ent is returned. Otherwise, a new Ent will be created from container_txt, and the ID of that Ent is returned:
autobits ent_id
dbserver will extract the AuthName from container_txt and validate that this account has free character slots. It will rename the character if there is a collision, and grant a rename token to the character if it does so. The container is then created and added to the SQL queue for writing. The container is immediately backed up into a hogg, and then unloaded.
When step is SHARDXFER_FULFILL_COMMIT_SRC:
autobits dbid
string dst_shard
autobits dst_dbid
autobits type
In this step, visitor transfers (when type is XFER_TYPE_VISITOR_OUTBOUND or XFER_TYPE_VISITOR_BACK) are handled differently: for these, dbserver finds the turnstile server for the destination shard, and sends it DBSERVER_COOKIE_REQUEST:
OrderId order_id
autobits dbid
autobits type
autobits dst_dbid
autobits auth_id
string account_name
bits(1024) auth_data
autobits home_shard_id
autobits dst_shard_id
For non-visitor transfers, dbserver instead sends AUCTION_CLIENT_ACCOUNT_SHARDXFER to AuctionServer, to begin the inventory transfer:
OrderId order_id
autobits dbid
string dst_shard
autobits dst_dbid
In development mode, dbserver skips the AuctionServer interaction and sends back a response to AccountServer with no further fields.
When step is SHARDXFER_FULFILL_COMMIT_DST:
autobits auth_id
autobits ent_id
dbserver sends an SQL update to remove the AccSvrLock field from the Ents table for ent_id, and sends ACCOUNT_CLIENT_MARK_SAVED to AccountServer:
autobits auth_id
autobits count // always 1 in this scenario
repeated count times:
OrderId order_id
then responds with ACCOUNT_CLIENT_SHARDXFER as usual, with no additional fields.
When step is SHARDXFER_FULFILL_COMMIT_RECOVERY:
autobits auth_id
dbserver searches the Ents table for entries with AccSvrLock matching this OrderId, and then runs the COMMIT_DST procedure on those rows. It then responds with:
bits(1) found
where found is 1 if any rows matched this OrderId, and 0 if none did.
When step is SHARDXFER_FULFILL_XFER_JUMP:
autobits dbid
dbserver sends a DBSERVER_RELAY_CMD to the client (forcibly loading offline characters onto a MapServer if necessary), with this command:
cmdrelay_dbid %s
shardxfer_jump
populated with dbid.
For this step, dbserver does not send a ACCOUNT_CLIENT_SHARDXFER response to AccountServer.
ACCOUNT_SVR_RENAME
OrderId order_id
bits(1) fulfill
autobits ent_id
When fulfill is false, dbserver will do some checks and then respond with ACCOUNT_CLIENT_RENAME:
OrderId order_id
bits(1) validating
bits(1) confirm
validating will be 1. confirm will be 1 if:
- The Ent is currently loaded (this may be a bug, it does not check for the renameable flag)
- There is an Ent in the SQL database with this ID, which is not locked, and the DbFlags column for that row has the DBFLAG_RENAMEABLE bit set.
When fulfill is true, the Ent will be loaded if necessary, forcibly loaded onto a MapServer if currently offline, and then sent a DBSERVER_RELAY_CMD with:
cmdrelay_dbid %d
order_rename %s
populated with ent_id and order_id
If the Ent is loaded, no response will be sent (bug), otherwise an ACCOUNT_CLIENT_RENAME will be sent with validating set to 0, and confirm will be set to 1 if the Ent was found and sent the command.
ACCOUNT_SVR_SLOT
OrderId order_id
autobits auth_id
dbserver increments the SlotCount field in the ShardAccount identified by auth_id and saves the container. It responds to AccountServer with ACCOUNT_CLIENT_SLOT:
OrderId order_id
bits(1) confirm
where confirm is 1 if the update was applied, and 0 if no ShardAccount with this ID could be found.
ACCOUNT_SVR_RESPEC
OrderId order_id
bits(1) fulfilling
autobits ent_id
When fulfilling is 0, dbserver checks the Ent identified by ent_id, and responds with ACCOUNT_CLIENT_RESPEC:
OrderId order_id
bits(1) validating
bits(1) confirm
where validating is 1 and confirm is 1 if the Ent exists and is not locked.
When fulfilling is 1, the Ent will be loaded if necessary, forcibly loaded onto a MapServer if currently offline, and then sent a DBSERVER_RELAY_CMD with:
cmdrelay_dbid %d
order_respec %s
The response will have validating set to 0 and confirm set to 1 if the Ent was found and a command sent. The response might not be sent if the container is already loaded (bug).
ACCOUNT_SVR_NOTIFYTRANSACTION
autobits auth_id
autobits2 sku
autobits inv_type
OrderId order_id
autobits granted
autobits claimed
bits(1) success
The game client link for auth_id is found. If dbserver has a direct link to that client, nothing happens. Otherwise, dbsevers send a DBSERVER_ACCOUNTSERVER_NOTIFYTRANSACTION to the player's current MapServer with the same content as this message, except the auth_id is replaced with the entity ID of the player's current character.
ACCOUNT_SVR_NOTIFYREQUEST
autobits auth_id
autobits type
OrderId order_id
bits(1) success
string message
The game client link for auth_id is found. A DBGAMESERVER_ACCOUNTSERVER_NOTIFYREQUEST is sent with the same content as this message, without the auth_id.
ACCOUNT_SVR_NOTIFYSAVED
autobits auth_id
autobits type
OrderId order_id
bits(1) success
string message
The game client link for auth_id is found. If there is a direct connection to the dbserver, nothing happens. Otherwise, a DBSERVER_ACCOUNTSERVER_NOTIFYSAVED is sent to the MapServer where that client is connected, with the same content as this message, with the auth_id replaced by the ent_id of the player's current character.
ACCOUNT_SVR_INVENTORY
autobits auth_id
autobits count
repeated count times:
autobits2 sku
autobits granted_total
autobits claimed_total
autobits expires
packint(1) shard_xfer_free_only
autobits shard_xfer_tokens
bits(128) loyalty_status
autobits loyalty_points_unspent
autobits loyalty_points_earned
autobits virtual_currency_balance
autobits last_email_time
autobits last_num_emails_sent
This data is stored in the ShardAccount container, and then either sent to the game client or MapServer as DBGAMESERVER_ACCOUNTSERVER_INVENTORY or DBSERVER_ACCOUNTSERVER_INVENTORY
ACCOUNT_SVR_CERTIFICATION_GRANT_ACK
ACCOUNT_SVR_CERTIFICATION_CLAIM_ACK
ACCOUNT_SVR_CERTIFICATION_REFUND_ACK
ACCOUNT_SVR_MULTI_GAME_TRANSACTION_ACK
ACCOUNT_SVR_MULTI_GAME_TRANSACTION_COMPLETED
ACCOUNT_SVR_FORCE_LOGOUT
autobits auth_id
The game client connected for auth_id is forcibly disconnected, notifying connected MapServer or QueueServer.
ACCOUNT_SVR_DB_HEARTBEAT
arena
This service supports the same protocol messages as the db service, documented below. It is used for ArenaServer to connect to dbserver, and the remote socket address of the ArenaServer connected on this port is used in processing DBCLIENT_REQ_ARENA_ADDRESS, but this service is not otherwise different.
auction
AuctionServer connects to this service. It can receive the following commands:
AUCTION_SVR_CONNECT (2)
The message has no parameters. dbserver will accept only a single connection, and while it has one, it will respond to all further AUCTION_SVR_CONNECT messages by closing the connection.
dbserver responds with AUCTION_CLIENT_CONNECT (2):
packint(1) protocol_version
string shard_name
bits(1) have_inactive_players
something....
AUCTION_SVR_SEND_INV (3)
autobits entity_id
string inventory
dbserver finds the mapserver for entity_id, and proxies the message there as DBSERVER_AUCTION_SEND_INV
inventory is eventually decoded by AuctionInventory_FromStr in the mapserver, but dbserver proxies it without inspecting its value.
AUCTION_SVR_SEND_HISTORYINFO (4)
autobits entity_id
string identifier
autobits buying_count
autobits selling_count
autobits history_count
repeated history_count times:
autobits date
autobits price
dbserver finds the mapserver for entity_id, and proxies the message there as DBSERVER_AUCTION_SEND_HIST.
AUCTION_SVR_BATCH_SEND_ITEMINFO (5)
autobits entity_id
zipped data
dbserver finds the mapserver for entity_id, and proxies the message there as DBSERVER_AUCTION_BATCH_INFO. The zipped data is not inspected by dbserver.
After this output packet has been queued, dbserver sends AUCTION_CLIENT_DATAOK to the AuctioServer, with no both. This is a primitive form of flow control. It does not wait for the message to be sent to the mapserver before doing this.
AUCTION_SVR_XACT_CMD (7)
autobits entity_id
autobits type
XactCmd cmd
dbserver finds the mapserver for entity_id. If there is one, it proxies the message there as DBSERVER_AUCTION_XACT_CMD. If there is no mapserver, then dbserver responds to AuctionServer with AUCTION_CLIENT_XACT_UPDATE, sending:
autobits xid
autobits subid
autobits result
Where xid and subid are taken from cmd, and the result is set to kXactCmdRes_No.
AUCTION_SVR_RELAY_CMD_BYENT (9)
packint(1) entity_id
packint(1) force
string msg
dbserver finds the mapserver for entity_id. If there is one, it sends DBSERVER_RELAY_CMD there with msg as the body. If there is no mapserver, and force is set to 1, then the message is queued for relaying when the entity is available, and dbserver begins attempting to load the entity into a mapserver.
AUCTION_SVR_THROTTLE_ON (10)
This message has no parameters, and dbserver sends no response. It enables throttling, which prevents some (???) messages from being sent to the AuctionServer.
AUCTION_SVR_THROTTLE_OFF (11)
This message has no parameters, and dbserver sends no response. It disables throttling.
AUCTION_SVR_ACCOUNT_SHARDXFER (12)
OrderId order_id
autobits dbid
dbid is interpreted as an Ent id. dbserver will offline (???) and delete (???) the player, and then send AccountServer an ACCOUNT_CLIENT_SHARDXFER with:
OrderId order_id
autobits SHARDXFER_FULFILL_COMMIT_SRC
beacon
This service is used for the beacon servers and clients to connect to dbserver. It consists of two network ports, one for clients and one for servers.
All messages on the beacon client port are ignored.
Only one message is handled on the beacon server port. It is:
BEACON2DB_BEACONSERVER_STATUS
packint(1) version
packint(1) longest_wait
version is ignored. When dbserver receives this packet, it records longest_wait and the time when this message was received.
This information is not used for any purpose other than relaying to ServerMonitor.
client
This service is used for the game client to communicate with dbserver.
It is documented on Client-to-dbserver
db
This service is used to communicate with MapServer and RaidServer.
It is documented on Dbserver-to-mapserver
launcher
This service is used for launchers to connect to dbserver and receive instructions on what processes to start. It forms a primitive job scheduler, attempting to start processes on launchers which have spare capacity.

queue
This service is used for the QueueServer to connect to dbserver. Only one connection is allowed.
The use of the QueueServer is optional. When it is used, game clients connect to QueueServer instead of dbserver, and QueueServer proxies all the usual Client-to-dbserver messages.
Proxied messages for clients, sent from dbserver to QueueServer, will be prefixed with these fields to identify the client they are for:
string client_name
autobits link_id
Proxies messages from clients, send from QueueServer to dbserver, will be sent in QUEUECLIENT_CLIENTCOMMAND messages.
QUEUESERVER_SVR_CONNECT
QUEUESERVER_SVR_ERROR
QUEUESERVER_SVR_ENQUEUESTATUS
QUEUESERVER_SVR_UPDATE
QUEUESERVER_SVR_REMOVECLIENT

stat
This service is used for StatServer to connect. It is used to identify the StatServer in order to send messages to it. It supports the same messages as the db service, and is not otherwise different.
svrmon
This service is used for ServerMonitor to connect to dbserver. Many ServerMonitors can connect to the service simultaneously.
Unusually, this service reuses command numbers for requests and responses, instead of having two distinct namespaces for messages in each direction.
