f0112290c6 Disallowed deletions from RDB$DATABASE. This fixes the only problematic part of CORE-3735: Unprivileged user can delete from RDB$DATABASE, RDB$COLLATIONS, RDB$CHARACTER_SETS. The implemented solution could be used to protect other system tables from direct modifications. 2012-01-20 10:23:31 +00:00

c44c548f8c Corrections and cleanup. 2012-01-09 00:08:33 +00:00
dimitr
e956e2e6c0 1) Restricted ALTER/DROP permissions to the object owners only. Now this applies to domains, charsets, collations, generators and exceptions. This fixes CORE-304: Metadata security hole - any user can alter/drop generators and exceptions. 
2) Opened the gates to implement the standard USAGE privilege (CORE-2884). SQL support and validation logic are still to be developed.
3) Added the grant option to the owner permissions for packages, procedures and functions.
4) Misc cleanup and refactoring.

ca1a67992c Return explicit sign of active transaction from VIO_get_current() - it makes logic more clear in check_duplicates() and allows to clear transient lock error from status vector and not propagate up to the callers. 
Cleanup : removed my old disabled code (checking for old and new values) and restored original code in check_duplicates().

809fba5ec9 Reworked the garbage collector thread: 
- a single try-catch block looks better
- cross-helping between GC and CW/CR threads is agreed to be a bad idea
- replaced ATT_disable_gc_notify with a check inside notify_garbage_collector()
- made the logic more straightforward
Careful review would be appreciated.

88b8a40a04 1. Cleaned up most of SUPERSERVER usage. 
SUPERSERVER has 4 different meanings in our code:
- this is milticlient server (replaced with Config::getMultiClientServer())
- use shared data cache (replaced with Config::getSharedCache())
- use shared metadata cache (replaced with macro SHARED_METADATA_CACHE)
- database are NOT shared between processes (replaced with getSharedDatabase())

2. Use fb_smp_server as both superclassic and classic binary on posix
(xinetd autodecection is done).

3. Small posix build cleanup.

11495a55fb Refactored the whole RSB stuff into classes. They're inside the /recsrc sub-directory now. 
Fixed the layering for WITH LOCK and (partially) ANY/ALL predicates.
Cleaned up the outdated code that never worked (mapping DISTINCT to an index, some VMS remainings).
Wiped out a lot of the pre-ODS11 optimizer logic. Some minor adjustments there.
Re-implemented the full outer join from scratch. This resolves CORE-2678 (full outer join cannot use available indices).
Resolved CORE-2796: DB_KEY is always zero for external tables.
Implemented the core part of the scrollable PSQL cursors. Implementation is still incomplete, but ready for testing.
Some other changes I don't recall at the moment ;-)

WARNING! The engine may be unstable. Please email me about any issues found.

ed0e0daeb3 - External Engines implementation. 
- Plugins API.

- Feature CORE-2700 - UDR (User Defined Routines) Engine - C++ API supporting functions, triggers and stored procedures.
- Feature CORE-2470 - Support for alternate format of strings literals.
- Feature CORE-2310 - DDL triggers.
- Feature CORE-2312 - PSQL Packages.
- Feature CORE-1209 - CONTINUE statement.
- Feature CORE-1180 - DDL syntax to change (not) nullable state of columns.
- Feature CORE-2090 - Support OVER () clause with current aggregate functions.

- Fixed CORE-2699 - Common table expression context could be used with parameters.

- Introduce ODS 12.0.

- Work in progress in type-safe parser.
- Refactor some DDL commands (procedures and triggers) from DYN to DdlNodes.
- Refactor virtual tables to use a class hierarchy instead of namespaces. This is basic thing, not based on the changes done in Vulcan. Window functions is based on this work.
- Refactor COMMENT ON and DROP FUNCTION from DYN to DdlNodes. COMMENT ON do not use GDML anymore, it uses DSQL with PreparedStatement class.
- Refactor EXECUTE BLOCK to StmtNodes.
- Refactor the IUDF to SysFunctions. That eliminates RDB$GET_CONTEXT and RDB$SET_CONTEXT from RDB$FUNCTIONS.

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.

e79f55708d 1. Cleanup - use Firebird::Semaphore instead of local events, removed code 
related with local events from isc_sync.cpp.

2. Cleanup - removed unused parameter 'number of events' from ISC_event_wait()
and two unused parameters from ISC_event_init().

3. Added SYSV-semaphore based implementation of IPC to isc_sync.cpp.
This should fix CORE-2102: Firebird 2.5 does not build on MacOS (Darwin).

4. Fixed use of posic CS without (x)inetd (i.e. fb_inet_server -s).

5. Fixed (to be reviewed by Dmitry) recovery after some process death in lock manager.

dimitr
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.

e913a10676 Normally, deleted records are represented by a stub which has no 
data so should not be used for VIO_data calls when building the
version chain.  Under some circumstances, however, the deleted
flag is set on a complete record version with a delta back version.
When that happens, the record should be retrieved
