Dependent Performance Schema tasks are public
There are several tasks that depend on WL#2360 Performance Schema. They’re all public now, so you can find the description of the whole set on forge.mysql.com.
WL#2333 SHOW ENGINE … LOCK STATUS
WL#2360 Performance Schema
WL#2515 Performance statements
WL#3249 SHOW PROCESSLIST should show memory
WL#4674 PERFORMANCE_SCHEMA Setup For Actors
WL#4678 PERFORMANCE_SCHEMA Instrumenting File IO
WL#4689 Deadlock Monitor
WL#4813 PERFORMANCE_SCHEMA Instrumenting Stages
WL#4816 PERFORMANCE_SCHEMA Summaries
WL#4878 PERFORMANCE_SCHEMA Trace
WL#4895 PERFORMANCE_SCHEMA Instrumenting Table IO
WL#4896 PERFORMANCE_SCHEMA Instrumenting Net IO
Which one has priority for this quarter? We don’t know. We have to decide by the end of this month.
There are also three tasks that WL#2360 depends on:
WL#2373 Use cycle counter for timing
WL#4601 remove fastmutex from the server sources
WL#4876 Parse options before initializing mysys
In at least one person’s opinion those three tasks are already taken care of, or can be resolved without affecting our schedule greatly. There has been a complaint that the timing code from WL#2373 is not “optimal” (true); however, let’s hope that people’s concern at this phase will merely be whether it is “fast” and “safe”.
The main task, WL#2360, is still in code review. It is now clear that code review and Quality Assurance
will not finish in the next week or two. So the plan now is that, when we release the source code for public viewing on April 20 2009, it will be part of a separate launchpad tree.
