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.
CORE-2780: Include client library version and protocol version in mon$attachments
CORE-2187: Return the Hostname in mon$attachments
CORE-3779: Report OS user name in MON$ATTACHMENTS
+ some cleanup.
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
- moved relation's counters into RuntimeStatistics.h
- renamed RuntimeStatistics::bumpValue to RuntimeStatistics::bumpRelValue and thread_db::bumpStats to thread_db::bumpRelStats to make things more clear
- removed not obvious cast in VIO_bump_count
- removed dependency of RuntimeStatistics.h from ntrace.h
- 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.
2. Avoid massive segfaults when closing heavily loaded server.
3. Restored logic in YValve required for correct shutdown.
4. Do not change externally visible request body when preparing it.
It's better to have one standard than two, and "ddl" was broken from API POV.
So make the IAttachment always the caller, explicit or implicit (via IStatement or IRequest), and pass the ITransaction as parameter.
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.
