This should eliminate race conditions caused by zones trying to set
a leader when members in different zones quit at the same time
Zone still detects when leader goes offline to trigger a change
since it's easier than having world process expedition member status
updates and perform expedition lookups
It isn't necessary to send this packet to current members when a new
expedition member is added. The member list packet changes the current
player count on the window
This fixes unnecessary packets and compass updates being sent for
invited members and better matches live's packet update pattern
This also fixes duplicate updates being sent to the added member
Live only sends a MemberListName update for members added through a
swap (player count doesn't change). For members added through an
invite it sends expedition info and a full member list update
A full member list update is sent for both cases in this patch. This
is because MemberListName currently always adds members with status
"unknown". This is either due to unknown packet fields or a change
in future clients
This exposes dynamic zone ids for any future changes and will make it
easier to preserve historic dz and expedition data. This also cleans up
some dynamic zone creation for expedition requests
When purging instances the expedition table is no longer updated
since dynamic zone ids are not re-used like instance ids are
Update #dz list commands to show dz id
Add GetDynamicZoneID and get_expedition_by_dz_id quest apis
All expedition members are notified not just those in dz
This will only work if the dz is running. It might make more sense to
move this to client or world processing so members are notified even if
the zone instance isn't running
This is a breaking api change
eq.get_expedition_by_instance_id(instance_id) is replaced with
eq.get_expedition_by_zone_instance(zone_id, instance_id)
This replaces the FindCachedExpeditionByInstanceID method of
obtaining expeditions via instance id with a new method that
requires the dz zone id as well
Also supports reducing lockout duration
Add Expedition::AddLockoutDuration
Add Client::AddExpeditionLockoutDuration
Some expeditions require adding to existing lockout durations
during progression. These add the specified seconds to individual
member lockout timers instead of setting a static duration based on
internal expedition lockout like UpdateLockoutDuration.
Add Group and Raid method DoesAnyMemberHaveExpeditionLockout
This is required by some expeditions that perform a manual check for
custom dialogue (Ikkinz group expeditions)
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)
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
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
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.
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
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.
