This implements the new behavior from live's September 16, 2020
(test server's September 8, 2020) patch
Expeditions can be created even when the client's group or raid
exceeds the expedition's max player requirement. Members are added
until the max player count is reached and the rest are ignored.
Raid members are added ordered by their raid group number with
ungrouped members having the lowest priority
Rename expedition request method ValidateMembers to CanMembersJoin
Change some expedition messages to System color (live changes)
Increases default from 15 minutes to 25 minutes
This compensates for current default graveyard timer code. Otherwise
instances may shutdown before graveyards can process any corpses.
A better fix needs implemented later to deal with corpses inside
expired dynamic zone/instances. Zones without graveyards should move
corpses to the non-instance version and zones with graveyards should
somehow still be processed (maybe offloaded to world?)
This was loading the dz from database to get safe return data every time
a client's dz removal timer triggered
Add the Zone::GetDynamicZone() method so zones that are dz instances can
find the data from the cache of any dz systems
On live, new expedition leaders are only notified if made leader from
the /dzmakeleader command (or from ui). This rule makes it so the new
leader is always messaged on a leader change for cases where previous
leader goes offline or quits
This prevents toggling to offline state before setting to and from
linkdead status. Without this change, a new expedition leader will be
chosen as soon as the current leader goes linkdead. On live an
expedition leader retains leadership while linkdead
Only choose an online member as new leader on leader changes
Keep leader online status updated in zone expedition caches
Currently this will also trigger a leader change if the leader goes
linkdead. On live the character retains leadership while linkdead
and a new one is only chosen once kicked offline
Set expedition's instance id NULL instead of deleting it from the
database when instances are deleted. Only expedition functions
should delete expeditions
This fixes a regression caused by removing foreign key constraints
The expedition_details row was being deleted and not the corresponding
expedition_members and expedition_lockouts rows. Any characters inside
the members table could no longer join expeditions
Remove logging unsanitized input
Make unsigned comparison not compare < 0
Cleanup some FormatName and string usage. Some of these strings could
probably be moved instead
Remove unnecessary expedition lookup in a world message handler
Add static expedition methods to add or remove character lockouts
Add CreateLockout static helper to ExpeditionLockoutTimer
Refactor existing character lockout removal to allow removal of lockouts
for offline characters (was only used by #dz lockouts remove command)
Fix #dz list member count
Remove extra cross zone message server opcode and struct. Existing
function already exists for normal messages
Group CZClientMessageString struct with other CZ structs
Some live expeditions update a lockout's duration during progression
The current AddLockout method replaces lockout timers. This updates the
expiration of an existing lockout by modifying the original duration
Only members are updated and not the internal expedition timer by
default. This is so new members receive the original duration like live
Add SetLootEventByNPCTypeID and SetLootEventBySpawnID quest apis
These associate events with npcs or entities inside the dz to prevent
them from being looted by characters that didn't receive the event
lockout from the current expedition.
This fixes an exploit that allowed a player that already had a lockout
from another expedition being added to loot after the event is complete
Instead of allowing all previous members to bypass a replay timer
conflict, only allow if expedition uuid of the lockout matches
This fixes an exploit for expeditions that add delayed replay timers.
Members could be part of an expedition on creation and then quit to form
another expedition. They could then always be re-invited to the original
expedition even with a conflicting replay timer lockout.
Breaking change to the current API
has_replay_timer column removed from expedition_details table
This argument is unnecessary and just creates confusion. Expedition
replay timers use a hardcoded name precisely for this purpose and
those lockouts are already being checked on creation requests.
Ignore expired state of replay timers when assigning to new members
This fixes a regression from a previous change that stopped assigning
expired lockouts to new members. Only expired event timers should be
ignored for new members. Replay Timers should always be added with a
a fresh lockout
Live requires characters that quit an expedition to zone out before
being re-added. This is probably to avoid exploiting max player
requirements by constantly swapping players in and out
Delete pending lockouts of members on expedition creation
Delete pending lockouts when all members removed from expedition
This fixes an edge case where members could incorrectly be assigned
pending lockouts that were never cleared from the database (from a
server crash or other situation) after entering another dz.
Small cleanup of logic and unused variables
Rename LoadValidationData to LoadMembersForCreateRequest
Remove unnecessary early string building for members query
Remove unnecessary lockout expired check for leader messages
This optimizes character status requests by only sending a single
bulk request to world for characters in all expeditions instead of
sending a separate request for each expedition on zone startup
This optimizes caching all expeditions by loading dynamic zone data and
expedition members in bulk instead of for each expedition separately.
This reduces the number of queries from 1+2n to 3 total.
Expedition members are now joined in the initial query since empty
expeditions aren't cached anyway. Optional internal lockouts for all
cached expeditions are loaded in a single bulk query afterwards.
Dynamic Zone data is also loaded as a single bulk query afterwards to
simplify processing and keep dz database logic separated. It might be
worth investigating if joining dz data in the initial expeditions load
query is worth refactoring for.
This fixes an edge case with client invites sometimes failing because
an expired lockout hasn't been removed from client yet
Clients no longer receive expired lockouts from expeditions when joining
Make quest compass a vec3 to remove include dependency
Quest compass location doesn't require a zone id since it can only be
set in the zone that it's drawn in. Drop the DynamicZoneLocation member
and forward declare to remove the dependency on header.
Move ExpeditionInvite struct to zone common header
Including expedition.h in client.h just to use the ExpeditionInvite struct
is an unnecessary header dependency that increases incremental build time.
This allows expedition classes to be forward declared in client header.
Since world now tracks empty expeditions it can determine when to
shutdown dynamic zone instances when the rule is enabled rather than
letting zones do it.
Zones are no longer able to delete expeditions. World now tracks empty
expeditions in cache and only deletes them when it detects an
expedition's dynamic zone instance has no more clients inside.
This fixes an exploit where lockouts couldn't be applied to expeditions
after all members were removed because zones were deleting the expedition
immediately. Clients still inside the dz were able to complete events
before being kicked from the instance while not having an expedition.
Expeditions are no longer purged from database in the world purge
instance timer to avoid a possible race with this new system
This implements a small cache in world to track expedition states.
This fixes expired expeditions being left in zone caches unless the
expedition's dz instance was running to detect it (or unless an
expedition was deleted via a client using /kickplayers). This was also
leaving clients in a ghost expedition that no longer actually existed
Not all expeditions with a replay timer lockout add it to newly
added members automatically
This adds the Expedition::SetReplayLockoutOnMemberJoin(bool) method
to the quest api so it can be disabled
