Description
The following example will cause corruption due to the extra NULs at the end of the first string:
#include <libmcsapi/mcsapi.h>
|
#include <iostream>
|
|
|
int main(void) |
{
|
mcsapi::ColumnStoreDriver* driver = nullptr;
|
mcsapi::ColumnStoreBulkInsert* bulk = nullptr;
|
try { |
driver = new mcsapi::ColumnStoreDriver(); |
bulk = driver->createBulkInsert("test", "t1", 0, 0); |
bulk->setColumn(0, 1);
|
std::string str("hello world1"); |
str.resize(14);
|
bulk->setColumn(1, str);
|
bulk->writeRow();
|
bulk->setColumn(0, 2);
|
bulk->setColumn(1, "hello world4"); |
bulk->writeRow();
|
bulk->setColumn(0, 3);
|
bulk->setColumn(1, "hello world9"); |
bulk->writeRow();
|
bulk->setColumn(0, 4);
|
bulk->setColumn(1, "hello world16"); |
bulk->writeRow();
|
bulk->commit();
|
} catch (mcsapi::ColumnStoreError &e) { |
std::cout << "Error caught: " << e.what() << std::endl; |
}
|
delete bulk; |
delete driver; |
}

Can't reproduce the bug on Ubuntu 16.04 and CentOS 7.
Locally copied test/mcol-1154.cpp and test/CMakeLists.txt from branch MCOL-1154 to branches master and develop-1.1.
Compiled and installed branch master with flag TEST_RUNNER=ON and ran make check. All 16 tests including mcol-1154 passed.
Compiled and installed branch develop-1.1 with flag TEST_RUNNER=ON and ran make check. All 16 tests including mcol-1154 passed.
Compiled and installed branch MCOL-1154 with flag TEST_RUNNER=ON and ran make check. All 16 tests including mcol-1154 passed.
More information about failing OS or bug needed. Maybe test case needs to be adapted to show the actual bug.
Fixed the test, only worked if table was already created and had been queried due to caches.
Root cause is completely wrong, abandoning this one and opening a new bug.
Patch trims off trailing NULs from VARCHAR/CHAR/TEXT data.
For QA: test mcol1154 included in regression suite
