WL#3089: Refactoring for multi-source and info system tables
Affects: Server-7.1 — Status: Assigned — Priority: Medium
DESCRIPTION Take refactoring parts of the WL#1697 Multi-source code (that have already been agreed with/preliminary reviewed by Mats and Guilhem), port it to MySQL version 5.2 and push it. RATIONALE Doing this first step will 1. make the code easier to maintain 2. make multi-source easier to implement, 3. make info system tables be easier to implement.
Since this is only refactoring and it has been discussed/reviewed before, I hope no long descriptions are needed and we can instead study the patches.
