Ah, you were faster than I could write. Sorry for me being so persistent. Unfortunately I am unable to post a file in the bug tracker now that the issue is resolved, therefore I write you here.

 

The good thing is, 1.4.3 improved the situation. One cyclic reference has gone away but there’s still one cyclic reference left to be broken. The attached objgraph shows that the one left might be the callback function which is stored in the EventBlock upon creation. You could break that by cleaning up the callback attribute on close(). Doing that should resolve this issue for good.

Awesome! Thanks for the fast responses, you’re doing a good job. J If you feel like sending me a patch that I can apply before you push 1.4.3 out of the door, I’ll gladly run my test scripts on a patched 1.4.2.

 

Cheers

Hi,

> great to hear that you have got this release out of the door so quickly. However, I’m afraid that http://tracker.firebirdsql.org/browse/PYFB-43 is not yet resolved. As posted in the issue I was just now able to reproduce the memory leak with 1.4.2. Thus, people, beware from invoking event_conduit() in a loop!
