Fast Transport fix

fix for LP#1444575.

This checkin addresses an issue with size of the buffer where

we get the row before conveting to delimited format. The

buffer in this case is a single row buffer.

Fixes in T2 driver to enable OE performance run

Following errors are ignored at the T2 jdbc driver to conform

to JDBC/ODBC Standard.

ERROR[8605] Committing a transaction which has not started.

ERROR[8609] Waited rollback performed without starting a transaction.

Memory corruption causing java core in T2 OE run.

Row count is treated as 32 bit integer while SQL expects 64 bit

numeric value to be passed to SQL_EXEC_GetDiagnosticsStmtInfo2.

This was causing the corruption.

There was a possibility that the row count buffer was used

after de-allocation. Fixed this code in Type2 JDBC driver

LP 1444044, dup col definitions are not detected

During a create table or create view, duplicate col

names are not being detected and an error is not being

returned. This results in an incorect table or view

being created. An error may or may not be returned

later depending on how that object is being used.

That has been fixed to detect dup cols and return an

error message during create time.

Fixing it now so users dont create incorrect objects

by mistake.

Fix for bug 1442932 and bug 1442966, encoding for varchar

Submitting this before finishing regressions on workstation, in the

interest of time.

Key encodings for VARCHAR values used to put a varchar length indicator

in front of the encoded value. The value was the max. length of the

varchar and the indicator was 2 or 4 bytes long, depending on the

length of the indicator in the source field. That length used to

depend only on the max number of bytes in the field, for >32767

bytes we would use a 4 byte VC length indicator.

Now, with the introduction of long rows, the varchar indicator length

for varchars in aligned rows is always 4 bytes, regardless of the

character length. This causes a problem for the key encoding.

We could have computed the encoded VC indicator length from the field

length. Anoop suggested a better solution, not to include the VC

indicator at all, since that is unnecessary. Note that for HBase row

keys stored on disk, we already remove the VC indicator by converting

such keys from varchar to fixed char. Therefore, the issue happens

only for encoding needed in a query, for example when sorting or in a

merge join or union.

Description of the fix:

1. Change CompEncode::synthType not to include the VC length

indicator in the encoded buffer. This change also includes

some minor code clean-up.

2. Change the assert in CompEncode::codeGen not to include the

VC indicator length anymore.

3. Changes in ex_function_encode::encodeKeyValue():

a) Read 2 and 4 byte VC length indicators for VARCHAR/NVARCHAR.

b) Small code cleanup, don't copy buffer for case-insensitive

encode, since that is not necessary.

c) Don't write max length as VC length indicator into target

and adjust target offsets accordingly (for VARCHAR/NVARCHAR).

4. Other changes in sql/exp/exp_function.cpp:

d) Handle 2 and 4 byte VC len indicators in hash function

and Hive hash function (problems unrelated to LP bugs fixed).

e) Add some asserts for cases where we assume VC length indicator

is a 2 byte integer.

CompDecode is not yet changed. Filed bug 1444134 to do that for

the next release, since that change is less urgent.

Patch set 2: Copyright notice changes only.

Patch set 3: Updated expected regression test file that

prints out encoded key in hex.

Temporary fix for LP bug 1438372

Hold and set CQD optimization_level to 3 during DDL query compilation

when hash joins and merge joins are turned off. This is to prevent the

optimization level set by user to other than 3 (maximum) to affect

meta-data queries. In the future, any secondary compiler won't get any

user CQDs, thus this is temporary fix as work-around.

LP Bug 1442949

-- alter add col was not running under an internal Xn.

that caused rollback to not work.

-- change to allow internal cleanup command to proceed if

running under a transaction. This is needed for internal

cleanups after error.

-- better error msg if index population fails.
