描述

Improvement from the https://github.com/StackStorm/st2-packages/issues/429

Most of the networking-related logic needs retrying mechanism. This is a rule of dumb in any package manager/client since in reality failures occur pretty frequently.

StackStorm shouldn't be an exception in following more reliable strategy.

TODO

  1. Add retry, timeout, delay-on-retry logic to st2client httpclient
  2. st2 pack retry logic for git cloning and any networking-related requests.

研究方向
Examine the HTTP client in st2client/utils/httpclient.py and add retry logic using requests' HTTPAdapter with Retry. Also update pack management functions in contrib/packs/actions/pack mgmt/download.py and st2common/st2common/services/packs.py to apply retries for git cloning and networking. Use the resources provided: requests documentation and adapters. The goal is to implement exponential backoff with configurable retries and timeouts.
