Project Description

urlparse4 is a performance-focused replacement for Python’s urlparse module, using C++ code from Chromium’s own URL parser.

It is not production-ready yet.

Many credits go to gurl-cython for inspiration.

Differences with Python’s urlparse

urlparse4 should be a transparent, drop-in replacement in almost all cases. Still, there are a few differences to be aware of:

  • urlparse4 is 2-7x faster for most operations (see benchmarks below)
  • urlparse4 currently doesn’t pass CPython’s test_urlparse.py suite due to edge cases that Chromium’s parser manages differently (usually in accordance to the RFCs, which urlparse doesn’t follow entirely).
  • urlparse4 only supports Python 2.7 for now

How to test

You must have Docker installed and running. You can run CPython’s test suite for urlparse like this:

make docker_build
make docker_test

Benchmarks

We are testing the following librairies on a sample of 100k URLs from Blink and DMOZ:

Each of them is being tested on a few different types of operations (basic urlsplit, relative link resolution, hostname extraction)

Here is how to launch the tests:

make docker_build
make docker_benchmark

Current results on a 2.2GHz Intel Core i7 MBP (in seconds):

Benchmark results on 104300 URLs x 10 times, in seconds:
