I did so with patchy, my package for patching the source code of functions at runtime. I came up with a solution to change requests to use a default timeout. New third party and first party code “slipped through the net” and was deployed without a timeout. This caused other important background work to be delayed, with knock-on effects.Īuditing the codebase to add missing timeout parameters only got so far. Remote server outages caused background tasks to take 45 minutes instead of 4.5 seconds, waiting for responses that wouldn’t come. This “missing default” has caused several production incidents at my client ev.energy.

httpx learned a lesson from this and it has default timeout of five seconds. Issue #3070 tracks the discussion on adding such a default timeout, but it has been open several years. This means that requests can hang forever if the remote server doesn’t respond, unless the author remembered to add a timeout. timeout only effects the connection process itself, not the downloading of the response body. One wrinkle in requests’ design is that it has no default timeout. session requests.Session () > adapter TimeoutHTTPAdapter (timeout (3, 60), maxretriesRetry (total5, backofffactor1.5, allowedmethodsFalse, statusforcelist 429, 500, 502, 503, 504)) > session.mount (' adapter) > session.mount (' adapter) > starttime time.monotonic () > try. Even if you don’t use it directly, it’s highly likely one of your dependencies does.
