Hello,

 

Back in March, I’ve posted a patch at http://bugs.python.org/issue26526 -- “In parsermodule.c, replace over 2KLOC of hand-crafted validation code, with a DFA”.

 

The motivation for this patch was to enable a memory footprint optimization, discussed at http://bugs.python.org/issue26415

My proposed optimization reduces the memory footprint by up to 30% on the standard benchmarks, and by 200% on a degenerate case which sparked the discussion.

The run time stays unaffected by this optimization.

 

Python Developer’s Guide says: “If you don’t get a response within a few days after pinging the issue, then you can try emailing python-dev@python.org asking for someone to review your patch.”

 

So, here I am.
