Description

This PR improves resource management in file handle and HTTP response handling:

  1. setup.py: Replaced bare \open(...).read()\ with a \with\ statement to ensure the file handle is always closed, including on exceptions.
  2. src/utils/common.py: \create_github_issue()\ now stores the \urlopen\ response object, reads its content, and explicitly closes it after use. The \content\ variable is preserved for callers.

Type of change

  • Bug fix
  • New feature
  • Breaking change
  • Documentation update

Testing

Tested with Python 3.11 on Windows 11:

  • Verified \setup.py\ can read README.md correctly
  • Verified HTTP response is properly closed after reading
  • No \ResourceWarning\ messages during execution

Impact

  • \setup.py: Context manager (\with\ statement, PEP 343) ensures proper cleanup of README file handle.
  • \src/utils/common.py: HTTP response is explicitly closed after reading (not via context manager, since \urlopen\ returns a single response and we explicitly close it after extracting the bytes).

These are resource management improvements — the previous code was generally cleaned up by Python's garbage collector, but explicit cleanup is more robust and avoids relying on GC timing.

Hi @lxcxjxhx and thanks for the contribution!

I'll review the changes in more detail over the next few days and, if everything looks good, I'll proceed with the merge.

One minor note regarding the PR description: I think "resource management improvements" would be a more accurate description than "resource leak fixes", since the previous implementation was generally cleaned up by Python as well.

Also, the PEP 343 reference only applies to the setup.py change, as the HTTP response is explicitly closed rather than managed via a context manager.

Thanks for the review, @stasinopoulos!

Good point on the wording — I'll update the PR description to use
esource management improvements\ instead of
esource leak fixes, since the original code was indeed cleaned up by Python in many cases. This is a more accurate framing of the change.

Re: the PEP 343 reference — noted, I'll narrow the description to only mention context managers for the \setup.py\ change and call out the explicit close for the HTTP response separately.

I'll push the wording update shortly.
