session = Session() # reuse tcp connection
session.mount("http://", HTTPAdapter(max_retries=retries))

set -e, -u, -o, -x pipefail explanation

set -e, -u, -o, -x pipefail

The set lines

  • These lines deliberately cause your script to fail. Wait, what? Believe me, this is a good thing.
  • With these settings, certain common errors will cause the script to immediately fail, explicitly and loudly. Otherwise, you can get hidden bugs that are discovered only when they blow up in production.
  • set -euxo pipefail is short for:
set -e
set -u

Makefile template, usage: `make all_src_files[ debug=mode]`. From https://tech.davis-hansson.com/p/make/
# use bash as the default shell
SHELL := bash
# ensures each Make recipe is ran as one single shell session, rather than one new shell per line
.ONESHELL:
# use bash strict mode. http://redsymbol.net/articles/unofficial-bash-strict-mode/
.SHELLFLAGS := -eu -o pipefail -c
# remove target files when Make file failed
.DELETE_ON_ERROR:
# warning when referring the undefined variables
MAKEFLAGS += --warn-undefined-variables
