- Add generic HandleMySQLErrno() method.
- Add the ability to re-execute a certain statement if errorhandler resolved the situation succesfuly.
- Add support for MySQL errno´s 2006, 2013, 2048, 2055 - fixes automatic reconnection behaviour.
- Cleanup in affected code
NOTE: You should still be smart enough to configure your worldserver and authserver´s MaxPingTime to be lower than your MySQL´s wait_time.

branch : trunk
- Make the mysql connectionpool shared for async and syncrhonous connections.
- Allow configurable amount of connections for the pool
- Allow configurable amount of delaythreads
Note that delaythreads now only represent in-core threads. Whenever they execute a task they will pick a free connection from the pool instead of using their previously unique assigned connection.
The purpose of this design change is better distribution of SQL requests (no bottlenecks paired with idling) among available resources.
This also prevents a ¨memory waste¨ of preparing async prepared statements on synchronous connections (that were never called) - and vice versa. Now, connections aren´t explicitly async or synchronous, they serve both purposes.
Use at own risk, might cause instabilities.
Don´t forget to update your config files and clear your cmake cache.

branch : trunk
- DB Threading model update
* Get rid of ThreadBundleMask and bundled connection
* Implement configurable amount of Synch threads for databasepools
* Use modulus based algorithm to check for free synchronous connections instead of previous ¨get connection by thread key or bundlemask¨ feature
* Locks on mysql context objects are now managed outside the mysql query methods
Fixes issue #4058
Fixes issue #4059
Introduces a ton of more issues. Use at own risk. You were warned. Really.
Don´t forget to update your worldserver.conf
--HG--
branch : trunk
- Rewrite Field class to be able to store both binary prepared statement data and data from adhoc query resultsets
- Buffer the data of prepared statements using ResultSet and Field classes and let go of mysql c api structures after PreparedResultSet constructor. Fixes a race condition and thus a possible crash/data corruption (issue pointed out to Derex, basic suggestion by raczman)
- Conform PreparedResultSet and ResultSet to the same design standards, and using Field class as data buffer class for both
* NOTE: This means the fetching methods are uniform again, using ¨Field* fields = result->Fetch();¨ and access to elements trough fields[x].
* NOTE: for access to the correct row in prepared statements, ¨Field* fields = result->Fetch();¨ must ALWAYS be called inside the do { }while(result->NextRow()) loop.
* NOTE: This means that Field::GetString() returns std::string object and Field::GetCString() returns const char* pointer.
Still experimental and all that jazz, not recommended for production servers until feedback is given.
--HG--
branch : trunk
- Declare the datatypes used to determine transaction element data (prepared statement/adhoc query string) on a generic level in SQLOperation.h
- Implement variable SQL element data for SQLQueryHolder class so it can execute both prepared statements and adhoc queries
- Make MySQLConnection::Query for adhoc queries return pointer to type instead of an autopointer, the autopointer is now applied on higher level code just like the function for querying prepared statements
--HG--
branch : trunk
* Rename QueryResult class to ResultSet
* Rename QueryResult_AutoPtr to QueryResult
* Declare ACE refcounted auto pointer for PreparedResultSet class
--HG--
branch : trunk
- A few prepared statement implementations in authsocket as example.
- Add an ASSERT in MySQLConnection::Execute(PreparedStatement*) to catch faulty created statements
--HG--
branch : trunk
- Add basic prepared statement interface (without implementation and thus without testing, without resultset support).
- Based on raczman/Albator´s work on TrinityCore3
Build:
- Add sLog define ¨hack¨ in DatbaseWorkerPool.h to fix some more sLog errors temporarily
FYI: Builds on windows
--HG--
branch : trunk
- Implement sLog.outSQLDriver that will log SQL driver related events (non-content related).
- Queries will now be logged into this file as well instead of normal log file (requires debug build).
- Don´t forget to update your authserver.conf and worldserver.conf
Core/build:
- Fix non-PCH build
--HG--
branch : trunk
+ add support for compiling under MacOSX (thanks to elegos for the research)
NOTE: G3D requires a redefinition-hack under OSX, please see wiki for this info (dep-sources will not be changed)
--HG--
branch : trunk
- All "'xxx' will be initialized after 'yyy' when initialized here"
- Some "unused variable"
- Some "enumeration value 'xxx' not handled in switch"
--HG--
branch : trunk
Database Layer:
- Implement connection pooling: Instead of 1 delay thread per database, you can configure between 1 and 32 worker threads that have a seperate thread in the core and have a seperate connection to the MySQL server (based on raczman/Albator´s database layer for Trinitycore3)
- Implement a configurable thread bundle for synchroneous requests from seperate core threads (see worldserver.conf.dist for more info)
- Every mapupdate thread now has its seperate MySQL connection to the world and characters database
- Drop inconsistent PExecuteLog function - query logging will be implemented CONSISTENTLY later
- Drop current prepared statement interface - this will be done *properly* later
- You´ll need to update your worldserver.conf and authserver.conf
- You´re recommended to make a backup of your databases before using this.
* HIGHLY EXPERIMENTAL - USE AT OWN RISK *
* HIGHLY EXPERIMENTAL - USE AT OWN RISK *
etc.
