Use a default timeout of 30 seconds for all requests, and add a
REQUESTS_TIMEOUT Anymail setting to override.
(I'm making a judgement call that this is not a breaking change in the
real world, and not bumping the major version. Theoretically, it could
affect you if your network somehow takes >30s to connect to your ESP,
but eventually succeeds. If so, set REQUESTS_TIMEOUT to None to restore
the earlier behavior.)
Fixes#80.
Catch and re-raise requests.RequestException in
AnymailRequestsBackend.post_to_esp.
* AnymailRequestsAPIError is needed for proper
fail_silently handling.
* Retain original requests exception type, to avoid
breaking existing code that might look for specific
requests exceptions.
Closes#16
Simplify install to just `pip install django-anymail`.
(Rather than `... django-anymail[mailgun]`
All of the ESPs so far require requests, so just move
that into the base requirements. (Chances are your
Django app already needs requests for some other
reason, anyway.)
Truly unique ESP dependencies (e.g., boto for
AWS-SES) could still use the setup extra features
mechanism.
(Prep for installing backends as package extras)
* Extract AnymailRequestsBackend and RequestsPayload
to base_requests.py
* Don't define/require requests exceptions when requests
not available
