Sometimes when users customize the URLs for release, they use urls that don't have
the same format the python-build-standalone URLs. Namely, they may not have
the release_id component of the url. This would result in an error parsing such
urls.

To fix, refine the url parsing to check if a component is a valid numeric release id.

Fixes #3285

Summary of Changes

Hello @rickeylev, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request resolves an issue where custom release URLs, particularly those used with python-build-standalone, could lead to parsing errors if they did not conform to the expected format by omitting a numeric release ID. The changes introduce more resilient URL parsing logic, ensuring the system can correctly process a broader spectrum of custom URL structures without encountering failures.

Highlights

  • URL Parsing Robustness: Improved the URL parsing logic within the get_release_info function to gracefully handle custom release URLs that may not contain a numeric release_id component, preventing parsing errors.
  • Flexible Release ID Extraction: Modified the extraction of release_id from URLs to first validate if the relevant URL segment is a digit before attempting conversion to an integer. If a valid numeric ID is not found, a default release_id of 99999999 is assigned, anticipating newer URL formats.

Code Review

This pull request introduces a fix to handle custom release URLs that might not conform to the expected format, specifically by lacking a release_id. The implemented change robustly parses the URL to avoid errors. My review includes a suggestion to improve code clarity and maintainability by refactoring a magic number to a constant and simplifying the conditional logic.
