I'm using symfony 1.4/propel 1.4 for a project, which was made by other developer earlier. On that project, propel connection is taken by using following code
$con = Propel::getConnection(UsersPeer::DATABASE_NAME, Propel::CONNECTION_WRITE);
However it never closes the connection using
Propel::close();
I just searched that there are 1500+ such incidents of opening connection & I guess none of them is closing connection.
I know its always good practice to close connection but in present case, it seems I wont be able to fix them all as fixing all the incidents is definitely going to take lot of time, may be a whole day. So now I'm confused if I should fix that or not. If I let it be like that, will it have any performance impact?
EDIT: Just for reference
Part 2 of this question Use of closing database connection in php
If anything, explicitly closing connections may harm performance. PDO often caches connections from one request to the next, on the reasonable assumption that the next request will use the same credentials.
Edit: reading the docs, it looks to me like PDO::ATTR_PERSISTENT connections are cached regardless of any attempt to close them, so you might as well not bother.
