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.
