Created database revision define, this is located in version.h in common #define CURRENT_BINARY_DATABASE_VERSION 9057 - This revision define will need to be incremented each time a database update is made - Along with a revision define increment, you will need to update the db_update manifest located in: - https://raw.githubusercontent.com/EQEmu/Server/master/utils/sql/db_update_manifest.txt - An entry needs to be made at the bottom of the manifest, the entry is quite simple - Example: 9057|2014_11_13_spells_new_updates.sql|SHOW COLUMNS FROM `spells_new` LIKE 'disallow_sit'|empty| - This latest example is checking to see if the spells_new table contains the column 'disallow_sit', if its empty, the update needs to be ran - More examples of match types below: # Example: Version|Filename.sql|Query_to_Check_Condition_For_Needed_Update|match type|text to match # 0 = Database Version # 1 = Filename.sql # 2 = Query_to_Check_Condition_For_Needed_Update # 3 = Match Type - If condition from match type to Value 4 is true, update will flag for needing to be ran # contains = If query results contains text from 4th value # match = If query results matches text from 4th value # missing = If query result is missing text from 4th value # empty = If the query results in no results # not_empty = If the query is not empty # 4 = Text to match - The manifest contains all database updates 'Required' to be made to the schema, and it will contain a working backport all the way back to SVN - currently it is tested and backported through the beginning of our Github repo - On world bootup or standalone run of db_update.pl, users will be prompted with a simple menu that we will expand upon later: ============================================================ EQEmu: Automatic Database Upgrade Check ============================================================ Operating System is: MSWin32 (Windows) MySQL is in system path Path = C:\Program Files\MariaDB 10.0\bin/mysql ============================================================ Binary Database Version: (9057) Local Database Version: (9057) Database up to Date: Continuing World Bootup... ============================================================ Retrieving latest database manifest...
