-----------------------------------------
Summary: Memory leak during compile of insert statements
Key: TRAFODION-2252
URL: https://issues.apache.org/jira/browse/TRAFODION-2252
Project: Apache Trafodion
Issue Type: Bug
Components: connectivity-mxosrvr, sql-cmp
Affects Versions: any
Reporter: Suresh Subbiah
Assignee: Suresh Subbiah
Fix For: 2.1-incubating
In a loading application that uses rowsets and parameters in an UPSERT USING
LOAD statement to add rows to a table (without an index), the attached memory
was seen using gperftools heap profiler.
Leaks were identified in
(a) HvRoles_vec is an NAArray, but is alloocated in System heap and not
destroyed
(b) HQCParseKey has a NAList data member ( HQCDynParamMap_) that is allocated
on system heap and not destroyed
(c) in mxosrvr the method rePrepare2 allocates a char array that is not deleted.
This can be seen from attached svg files. Please download both files to a
directory and use any browser to open the .svg file
Items (a) & (b) will be addressed in a PR and item (c) in a subsequent PR.
