These contains various fixes, fixes that have history worked one in past
more then once as person as group, aswell @Wishmaster117. But due
various reasons we had to drop them due priority or simply timewise.
These fixes have recollected again by @Regrad based on his crash logs.
Most crash logs we have, i am talking 30+ of them, to many to post here.
@Regrad running a larger server 100+ real players with bots, which means
he will walk into issues that most of us wont or are extremely difficult
to reproduce.
@Regrad used LLM to solve them based on crash log and mentioned his
server crashes almost disappeared, instead of redoing every single PR
and pull them apart. I tried to keep his bunch of changes together as
whole, reviewed them, some redone, verified again etc etc. This is not
how would normally do this. But since i want @Regrad being able to
confirm, we need this in a package as a whole. Pulling them apart in the
current situation is simply to much, to complicated in the verification
process.
So this PR is open and in my opinion has priority above others, but
@Regrad is only person who can give the green light for the
mod-playerbot changes for now.
I, we spend huge amount of time into these issues over last couple of
months. I will put other PR's on hold for abit.

Fixes crashes and race conditions when bots perform group/guild/arena
operations by moving thread-unsafe code to world thread.
Potentially fixes#1124
## Changes
- Added operation queue system that runs in world thread
- Group operations (invite, remove, convert to raid, set leader) now
queued
- Arena formation refactored to use queue
- Guild operations changed to use packet queueing
## Testing
Set `MapUpdate.Threads` > 1 in worldserver.conf to enable multiple map
threads, then test:
- Group formation and disbanding
- Arena team formation
- Guild operations (invite, promote, demote, remove)
- Run with TSAN
cmake ../ \
-DCMAKE_CXX_FLAGS="-fsanitize=thread -g -O1" \
-DCMAKE_C_FLAGS="-fsanitize=thread -g -O1" \
-DCMAKE_EXE_LINKER_FLAGS="-fsanitize=thread" \
-DCMAKE_INSTALL_PREFIX=/path/to/install \
-DCMAKE_BUILD_TYPE=RelWithDebInfo
build
export
TSAN_OPTIONS="log_path=tsan_report:halt_on_error=0:second_deadlock_stack=1"
./worldserver
The crashes/race conditions should no longer occur with concurrent map
threads.
## New Files
- `PlayerbotOperation.h` - Base class defining the operation interface
(Execute, IsValid, GetPriority)
- `PlayerbotOperations.h` - Concrete implementations:
GroupInviteOperation, GroupRemoveMemberOperation,
GroupConvertToRaidOperation, GroupSetLeaderOperation,
ArenaGroupFormationOperation
- `PlayerbotWorldThreadProcessor.h/cpp` - Singleton processor with
mutex-protected queue, processes operations in WorldScript::OnUpdate
hook, handles batch processing and validation
