0dc0a4b595 Fix locking on big-endian architectures 
4e4d8002e5 extended locks to have 64-bit
keys in most cases, but some were left as 32-bit. However, code using
these 32-bit locks assumed that the significant bytes of the key's long
value started from lck_string[0], which is false on big-endian
architectures.  This commit adds Lock::getKeyString(), which gets a
pointer to the first used byte of lck_string, and should be used in
place of accessing lck_string directly.

99ad42ab82 This should fix the races while accessing the relation statistics inside dbb_stats. Reads/writes/fetches/marks are incremented (CCH) and read (INF) unprotected, as it's crash safe and read skews are acceptable. Other counters (both global and relation wise) are protected with a mutex. They're incremented on demand based on the attachment counters (via diffs). While being there, cleaned up the currently unused performance counters. 2016-01-24 21:14:18 +00:00

0891bc723d Fixed CORE-5041: Database may get corrupted after ALTER DATABASE ENCRYPT/DECRYPT issued multiple times per database open time 2015-12-10 16:58:58 +00:00

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.

a6d615c0cd Fix one of the reason for AV in the engine (see CORE-4680, test by Pavel Zotov at 18 Nov 2015). 
The race when gone attachment released database object while another attachment is initialized and uses same database object.
Could happens with shared cache (former SS) only.
