Implementation also includes changes in GPRE, but this utility is not complete - only commands, used in ISQL,
are working in code generator for new API.
New interface IUtl is added - it performs tasks, related with database objects (attachment, transaction, etc.),
but not requiring routing in YValve, i.e. client only tasks.
That packet may contain database name, command line for service and/or some other important and critical information.
To avoid such attack wire encryption is started before attaching database or service manager, right after connect.
Also should fix a number of issues found in Alpha1 regarding services attach.
- ability to wait with finite timeout
- separate counts of waiting readers and writers
- two interlocked operations are needed when lock granted to a waiting readers (despite of its amount)
2. Implemented prototype of TLS-based debugging helper holding information about 'What does firebird do now?"
Currently it's more or less ready for use with JAttachment::release().
This struct lost its main value (group various blr-related properties in a single parameter).
And since openCursor/fetch already split the message/buffer, it does not make sense anymore to have it.
1. Never allocate empty statement - always use att->prepare() to create statement interface
2. Separated IStatement into 2 parts - statement itself and resultset.
3. Added stmt->openCursor() (and att->openCursor() for unprepared statements) to create IResultSet.
4. Always use IMessageMetadata (former IParametersMetadata) to pass message fromat info from client,
therefore avoiding need in BLR generation in client applications.
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.
