user-agent-index's Introduction

User agent index

Starting from works from Google, Browserscope provides a list of regular expressions to extract some meanings of user agents, one of the headers sent by HTTP clients.

The rules was wrote before the machine learning era, for each user agent lines, you have to iterate over hundreds of regexp, and stop with the first match.

It's cute, deterministic but inneficient.

Lets add some index, and shortcut the path before iterating like a boar.

Test it

The code uses poetry for managing the few python libraries.

tree-sitter is a generic parser tool, using agnostic rules that you can compile for your target language. For python, the tool build a dynamic library, a .so file. build-parser.py compiles the regex grammar.

make

There is some unit tests, useful as code example and for hunting regressions.

The official tests fixtures from main ua-parser project are used, too.

user-agent-index's Issues

Security Policy violation SECURITY.md

This issue was automatically created by Allstar.

Security Policy Violation
Security policy not enabled.
A SECURITY.md file can give users information about what constitutes a vulnerability and how to report one securely so that information about a bug is not publicly visible. Examples of secure reporting methods include using an issue tracker with private issue support, or encrypted email with a published key.

To fix this, add a SECURITY.md file that explains how to handle vulnerabilities found in your repository. Go to https://github.com/athoune/user-agent-index/security/policy to enable.

For more information, see https://docs.github.com/en/code-security/getting-started/adding-a-security-policy-to-your-repository.


This issue will auto resolve when the policy is in compliance.
