Hi,
i found a segfault within fastbit. It seems to be related to in memory tables.
It appears when you select with a where condition filtering on a text column.
See attached code (data is still the same as in my previous testcase). Be sure
to remove my comment in the code to make it really crash ;)
Kind regards,
Andreas Streichardt
#include <ibis.h>
#include <iostream>
using namespace ibis;
void print_table_info(table *tab)
{
std::cout << "Resultset: " << tab->nColumns() << "x" << tab->nRows() << std::endl;
}
int main()
{
part *partition=0;
table *tab=0;
table *in_memory_select=0;
table *select_on_select=0;
try
{
partition=new part("/tmp/test");
if (!partition)
{
std::cout << "Couldn't create partition" << std::endl;
goto cleanup;
}
tab=table::create(*partition);
if (!tab)
{
std::cout << "Couldn't create tab" << std::endl;
goto cleanup;
}
print_table_info(tab);
in_memory_select=tab->select("uid,m_0000,m_yquit","1=1");
if (!in_memory_select)
{
std::cout << "Couldn't create in memory select" << std::endl;
goto cleanup;
}
print_table_info(in_memory_select);
// crashes
//select_on_select=in_memory_select->select("uid","m_yquit='1'");
// works
select_on_select=in_memory_select->select("uid","m_yquit=1");
if (!select_on_select)
std::cout << "Failure!" << std::endl;
else
print_table_info(select_on_select);
}
catch (const std::exception& e)
{
std::cout << "Got an exception: " << e.what() << std::endl;
}
catch (char *s)
{
std::cout << "Got a string exception: " << s << std::endl;
}
cleanup:
if (select_on_select)
delete select_on_select;
if (in_memory_select)
