c4530625d9 Undo log shouldn't depend on the outer transaction. 2008-10-16 05:36:36 +00:00
dimitr
e0db5f3ecd Splitted the undo log into two parts: in-memory one for initial undo items (but they're much more dense now) and on-disk (cached up to TempSpaceLimit) one for full record versions (used in update-in-place). 
This dramatically reduces the memory usage for bulk updates, thus solving CORE-1575 (serious memory bug on multiple update a table in a single transaction) and CORE-1477 (Avoiding excessive memory consumption by undo-log after series of updates) and predicting out-of-memory conditions that could often lead to record-level corruptions.

5d9c430674 Implemented improvement CORE-1928 : Allow EXECUTE STATEMENT to inherit access privileges of caller stored procedure or trigger. 
Allow to specify EXECUTE STATEMENToptional clauses in any (not fixed) order.
Use INTERNAL_PROVIDER for access to the current database by another user too.

0a9e8c8382 Implemented CORE-1751. The changes include: 
1) Make memory counters aggregated.
2) Add attachment pool and allocate appropriate resources out of this pool.
3) Always release attachments explicitly (via destructor).
4) Always delete user requests prior to attachment deletion.
5) Introduce memory usage counters per every monitoring object.
6) Misc refactoring.
Some pieces are still incomplete (although everything basically works), but I'd like to get feedback and testing sooner rather than later.

31ba754981 After talking to Ann, decided to disable several items: 
- obsolete items like WAL and JOURNAL (cleaned in the past)
- crud from attempts never finished like the shared cache manager for Classic
- DSQL nodes that aren't used. This allowed freeing some keywords.
The functionality was disabled by commenting the code. No code has been deleted.

a19dadb269 1.- Try to fix the mess caused by different data types used to represent bifields of SCL_ constants defined in scl.h, second round. 
2.- Prevent users from deleting system generators and modifying any entry in rdb$generators. VIO passes the task to DFW, the only problem being that the user gets the error when a commit is done, not before.

f4e7ebdd3b Implement rudimentary framework to track lifetimes of active BLOBs. 
This solves the following issues:
1) Outrageous memory consumption when blobs are converted from strings during request processing
2) Materialization doesn't cause invalidation of BLOB IDs too early.
Original behaviour caused errors with updatable views or procedures receiving BLOB arguments.
