Inline comments:
In `@scripts/ci/sandboxed_web_e2e.py`:
- Around line 132-139: Update the readiness-check flow around
socket.gethostbyname() to calculate the startup deadline before DNS resolution
and enforce an explicit timeout on the resolver. Ensure delayed DNS lookup
cannot block beyond startup-timeout, and preserve the existing private/loopback
validation and gaierror handling.
- Around line 132-140: Replace the hostname check around parsed.hostname with a
helper that resolves all IPv4 and IPv6 stream addresses via socket.getaddrinfo
using AF_UNSPEC, rejects DNS resolution errors and any private or loopback
result, and documents this behavior with a docstring. Ensure opener.open
connects using the validated address rather than re-resolving the original
hostname, while preserving the intended test-only exception if required. Add
full-coverage tests for IPv4, IPv6, multiple records, DNS failures, and
rebinding.
