当 tox 安装要求时定义超时

Question

I have a gitlab ci pipeline which basically do some stuff on the enviornment ( install python and other packages) then it simply run tox in order to run some tests.

stages:
  - check



before_script:
    # here you can run any commands before the pipelines start
    - apt-get -qq update && apt-get -qq install -y python3.9
    - apt-get install -y libpq-dev &&  apt-get install -y python3.9-dev
    - apt-get install -y build-essential && apt-get install -y gcc && apt-get install -y postgresql
    - apt-get install -y  postgresql-contrib && apt-get install -y  ffmpeg libsm6 libxext6
    - apt-get install -y git
    - pip install tox



check:
  stage: check
  image: gitlab.*****.com:****/*****
  environment: prod
  services:
    - name: docker:19.03.8-dind #20.10.7
      alias: docker
  only:
    - master
  script:
    - |
      echo "
      machine gitlab.*****.com
      login gitlab-ci-token
      password $CI_JOB_TOKEN
      " > ~/.netrc 
    - tox

This is my tox.ini :

[tox]
envlist =
    {python3.9}


[testenv]
passenv = *
setenv =
    AIRFLOW_HOME = /airflow_home
deps=
    pytest
    -r{toxinidir}/requirements.txt 
commands=
    pytest 

The problem is that when tox is building the env and installing the packages specified in the requirements.txt it returns a ReadTimeOutError .

I've tried to delete tox and simply run a pip install -r requirem.nets --default-timeout=200 and it worked.
So the problem seems to be a timeout. I'd like to define a timeout but i don't want to discard tox.

How can i do it?

Answer 1

tox is using pip under the hood, so you can use the same options, preferable as environment variables.

So, following https://pip.pypa.io/en/stable/topics/configuration/#environment-variables you need to convert --default-timeout into the PIP_DEFAULT_TIMEOUT variable.

You can use this variable either by setting it in CI and then use the passenv directive in your tox.ini , or you can set it directly in tox.ini via the setenv directive.

Relevant documentation for tox:

• https://tox.wiki/en/latest/config.html#pass_env
• https://tox.wiki/en/latest/config.html#set_env

Answer 2

You can change default install_command :

install_command = pip install {opts} --default-timeout=200 {packages}
