10.6.2

March 26 2026

Fixed

• Ensure PubNubAsyncioException always carries a valid PNStatus with error data instead of None.
• Handle cases where status or error_data is None instead of raising AttributeError.
• Match PubNubAsyncioException which is what request_future actually returns on failure.
• Handle -1 (unlimited) correctly since attempts > -1 was always true, causing immediate give-up.
• Use delay class defaults instead of config value which could be None causing TypeError on comparison.
• Prevent falling through to start a heartbeat after deciding to give up.
• Set all four timeout fields explicitly instead of a 2-tuple that left write and pool unset.
• On macOS and Linux, time.monotonic() does not advance during system sleep, causing socket and asyncio timeouts (310s subscribe) to stall for hours of wall-clock time. Add time.time()-based deadline checks that detect sleep and cancel stale requests within ~5s of wake.
• Use asyncio.wait() with periodic time.time() checks instead of a single monotonic-based wait_for(), yielding to the event loop between checks.
• Persistent single daemon thread monitors time.time() every 5s and closes the httpx session when the wall-clock deadline passes, interrupting the blocking socket read. Tracks deadlines per calling thread so concurrent requests (e.g., subscribe + publish) don't interfere. Only armed for long-timeout requests (>30s). Session is recreated for subsequent requests.

Modified

• Cover both asyncio and threads paths simulated clock jumps, normal passthrough, clean watchdog shutdown, per-thread deadline isolation, concurrent request independence, cleanup, and exception propagation.
• Ensure pubnub.stop() always runs to prevent non-daemon threads from blocking process exit.
• Enable presence heartbeat and use unique channel names so presence registers on the server.
• Restore cipher_key after use in send_file and pass it explicitly to download_file.
• Avoid collisions with stale data from prior test runs.
