41460d041a did away with memoization for rle_ (cost of mutex was too high). pthread_[get|set]specific does not provide enough keys to make sense as an alternative 2008-11-27 00:08:59 +00:00

ff0887624c Simplified the page locking conventions. 
Added paranoid calls to assertlock() to page.c

Fixed race in abort():

 - pick CLR LSN

 - release page lock

 - someone else updates page

 - lock page

 - apply undo

6d17442380 Major refactoring: 
- Changed operations to take only two arguments
     - No more hacks regarding log argument sizes

     - Set pageid = INVALID_PAGE if you want a logical operation

  - Ported operation implementations to new api; exposed + fixed a number of concurrency bugs

  - More fixes to prepare

  - Fixed to nested top actions

  - More coherent operations api / recovery implmentation

  - TnaiveHash* and Tinstant* are (and were already) broken, and are set for removal

  - Removed some instances of fail_unless

  - Fixed design flaws in blob implementation.

  - New naming convention for operation callback functions.
