Left some TODOs in FirebirdInterface.idl and utilities/ntrace/TracePluginImpl.cpp related to trace.
(redo with fix for Windows build, and left another TODO comment in FirebirdInterface.idl)
Errors and warnings are processed in IStatus independently. Completion code
is moved away from IStatus and returned directly by appropriate functions.
Replaced isSuccess() with more generic function getStatus(), which sets
appropriate bits in returned value when errors/warnings are present.
Also use same style when returning bytes' array and it's length in different
interfaces.
Fixed assertion in CCH_exclusive_attachment
Rolled back my changes required to let cancelOperation() enter engine after shutdown
Better locks' history in SyncObject
1. Frontported fix for CORE-3935 and CORE-3993.
2. Added debugging support for mutexes and rwlocks in Vulcan style.
Unfortunately after last 'svn up' build asserts in JrdStatement:71.
2) Reworked the lock manager synchronization: added the RAII mutex holders and avoided dirty reads for the shared memory.
3) Encapsulated lck_length into the Lock class + small related refactoring.
4) Front ported recent fixes from the v2.x branches.
5) Misc cleanup.
Also some cleanups, the most important are:
- meaningful ctor on Jrd::Lock, helping to avoid code dup
- avoid unneeded h-file dependencies, making boot build engine dependent
Refactored the shared counter to support multiple number spaces.
Changed att_id and tra_id to be generated sequentially (without caching), as agreed with Vlad privately.
Fixed CORE-2305: Make mon$statement_id value constant among monitoring snapshots.
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.
