more consistent

d5ec668334 Let UPDATE and DELETE statements ignore records already deleted in the same statement (but still visible because of stable cursor). 
It fixed bugs
CORE-5322 : Cascade deletion in self-referencing table could raise "no current record for fetch operation" error), and
CORE-5142 : Error "no current record to fetch" if some record is to be deleted both by the statement itself and by some trigger fired during statement execution

dc7aad88ed 1) Slightly refactored recheduling and checkout logic. 
2) Re-enabled checkouts in PIO routines, this resolves CORE-4179. Windows build may be broken, please validate.
3) Implemented faster reaction on asynchronous cancellation/shutdown requests.
4) Avoided locking dbb_sync in AST. This change also solves races during massive attachment shutdown.

139331c7e3 Enhanced memory leaks search - changed FB_NEW to FB_NEW_POOL, 
plain new to FB_NEW, making allocated with it blocks tagged with file/line.
Make related code slightly better readable.

f7e248ca63 Improvement CORE-4935 : Increase performance of backout of dead record version (or undo of just created primary record version) when backversions chain is too long 
Improvement CORE-4936 : Reduce internal contention in background garbage collector
Other small improvements: 
- garbage collector\sweep now skip record header if transaction is below OIT - it allows to reduce number of page fetches
- missed points to gather RECORD_FRAGMENT_READS and RECORD_BACKVERSION_READS statistics

2e78b5a7e0 Feature CORE-4707 : Implement ability to validate tables and indices online 2015-06-19 12:07:41 +00:00
dimitr
8744b80766 1) Reverted a more complex refetch logic introduced recently to its original state. 
2) Protected against an undo record being used in VIO modify/erase/writelock routines.
3) Avoided false deadlocks in read-committed transactions.
This should cure CORE-4369, CORE-4561 and CORE-4618 at once.
