SQL Memory allocation tracing and overflow detection

1) Added code to record stack info when given size of memory blocks are

allocated and dump these info out to a file or terminal if the

deallocation is not made at the time the heap is distructed. This works

for heaps constructed from NAMemory.

2) Fixed the memory debug code to detected memory overflow at the

de-allocation time.

These two features are enabled through environment variables in objects

compiled in debug mode. See sql/common/NAMemory.cpp for details.

3) Fixes for memory usage issues found when testing above code.

Fix of bug #1328730:

JDBC T4 getTables methods only returns leading 100 rows,

if the total results is larger than 100. The second fetch

of JDBC Driver gets nothing. MXOSRVR actually fetch all rows

in statments data buffer, but in the second fetch, server

sends the buffer starts at the same address as last fetch, in

which the leading bytes of previous fetch are all already set

to '0'.

To fix this, uses a offset in statment to mark the start address

for next fetch of the buffer.

This passes dev unit tests for this specific problem, and QA

regression tests.

==================================================================

OCT 29th:

Add initialization for SRVR_STMT_HDL.outputDataValue.pad_to_offset_8_

to 0, remove NULL(zero) validation for pSrvrStmt->outputDataValue._length

and pSrvrStmt->outputDataValue._buffer, for performance consideration.

Fix for LP bug 1376306

- With this fix bulk loading salted tables and indexes now generates parallel

plans. Both salted base tables and salted indexes were tested

- if attemp_esp_parallelism cqd is set to off an error is returned

- also removed unneeded variables from sqenvcom.sh

Merge "Add transaction id to tracing during transactional aggregation execution"

Two minor bug fixes.

Sourcing in sqenv.sh a second time takes a couple of seconds.

The fix makes this much faster.

The topMatch method of a rule needs to call Rule::topMatch first

before doing anything else, like casting the RelExpr passed in

to a specific node.

Use new HFIle location for HBase 0.98

The code to lookup the HFiles for a given table was changed

to accommodate their new location within the HDFS file system.

The location seems to have changed at some point between 0.94

and 0.98, although I could find no documentation of the change,

nor any HBase property that could be used to identify the

path to the filesystem node under which HFiles for tables

are stored. This change affects lookup of HFiles for the purpose

of estimating the number of rows in a table.

Interim DBSecurity deliver for December

1) Implement REVOKE ROLE RESTRICT. Previously dependent objects were

not detected. Launchpad bug #1370739.

2) REVOKE ROLE with a list of grantees would fail for all grantees after

the first. Now works for the entire list. Launchpad bug #1375494.

3) SHOWDDL ROLE now shows the GRANTED BY clause if the grantor is not

DB__ROOT. Launchpad bug #1374586.

4) Component privilege names can now be reserved names. Launchpad bug

5) Added tests to catman1/test135 for privileges and RI constraints.

6) Added support for REVOKE RESTRICT for RI constraints.

7) Added support for USAGE privilege for sequence generator.

This code has been reviewed by the database security team but additional

input is encouraged and welcomed.

Fix for bug 1378926 - error 8448 with java.lang.OutOfMemoryError

Trafodion SQL processes dump java heap at $MY_SQROOT/logs in the

format java_pid<pid>.hprof when java.lang.OutOfMemoryError exception is

raised.

There were local references/global references that were not being deleted

in the trafodion code and that was causing leak in Java objects.

HTableClient_JNI objects are now cleaned up from the Java side if the

corresponding java objects are left in in-use pool at the time of ODBC/JDBC

disconnect. This takes care of memory leak on the C++ heap and java object

heap for such cases.
