[Firebird-odbc-devel] Fix for serious memory leak in odbc driver

[<la...@t-...>]

Hello!

I noticed that the odbc driver has a serious memory leak, which happens
everytime a resultset is used. (When my program was accessing a interbase
database using the odbc driver, the memory went up like hell).

The conversions array in the file IscResultSet is never deleted.

Just complete in the destructor:

IscResultSet::~IscResultSet()
{
	close();

	if (metaData)
		delete metaData;

	// T. Lagally: Dont forget to free this!
	if (conversions)
	{
		reset();
		delete[] conversions;
	}
}

I didnt change anything in the cvs, because I am totally new to this list
and odbc driver. Maybe anybody from you can do this. Thanks!

I also have a question: I noticed that the odbc-driver is not threadsafe. It
looks like that even the underlying library from interbase is not
threadsafe? Do anybody has any information concerning that?

Greetings

Thomas Lagally

Hello:

 >> Just complete in the destructor:

I think this is more correct if you put it in the close method, what do 
you think?? :

void IscResultSet::close()
{
	reset();

	if (statement)
		{
		statement->deleteResultSet (this);
		statement->release();
		statement = NULL;
		}
}
