test(tls): add TLS SNI hostname normalization and redirect hop limit specs - #2589
Conversation
WalkthroughAdded HTTPX tests for TLS SNI normalization and redirect hop-limit enforcement. The tests cover normalized host input and redirect behavior below and at the 10-hop limit. ChangesHTTPX behavior tests
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to This change is intended to protect TLS SNI normalization and redirect-loop limits, but the new tests only validate local test helpers. It should not merge as coverage for those behaviors until the assertions exercise HTTPX behavior. Poem

isAllowedHop, and update the tests to invoke the corresponding production
behavior or public HTTPX redirect flow. Ensure assertions cover actual SNI
normalization and redirect-loop guarding, including a whitespace input case if
trimming is expected.

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift
Test the production behavior instead of local copies.
normalizeSNI and isAllowedHop are implemented inside the tests. The assertions therefore pass even if the production SNI normalization or redirect loop guard is broken. Call the production code, or exercise the public HTTPX behavior with a real redirect chain and TLS test setup. Add a whitespace case if trimming is part of the stated coverage.
