1# This is a vpython "spec" file. 2# 3# It describes patterns for python wheel dependencies of the python scripts in 4# the chromium repo, particularly for dependencies that have compiled components 5# (since pure-python dependencies can be easily vendored into third_party). 6# 7# When vpython is invoked, it finds this file and builds a python VirtualEnv, 8# containing all of the dependencies described in this file, fetching them from 9# CIPD (the "Chrome Infrastructure Package Deployer" service). Unlike `pip`, 10# this never requires the end-user machine to have a working python extension 11# compilation environment. All of these packages are built using: 12# https://chromium.googlesource.com/infra/infra/+/main/infra/tools/dockerbuild/ 13# 14# All python scripts in the repo share this same spec, to avoid dependency 15# fragmentation. 16# 17# If you have depot_tools installed in your $PATH, you can invoke python scripts 18# in this repo by running them as you normally would run them, except 19# substituting `vpython` instead of `python` on the command line, e.g.: 20# vpython path/to/script.py some --arguments 21# 22# Read more about `vpython` and how to modify this file here: 23# https://chromium.googlesource.com/infra/infra/+/main/doc/users/vpython.md 24 25# This Python file gets its own vpython spec since it doesn't actually need that 26# many dependencies and trying to load all dependencies from the main .vpython3 27# spec on ChromeOS VMs runs into disk space issues. 28 29python_version: "3.8" 30 31# The default set of platforms vpython checks does not yet include mac-arm64. 32# Setting `verify_pep425_tag` to the list of platforms we explicitly must support 33# allows us to ensure that vpython specs stay mac-arm64-friendly 34verify_pep425_tag: [ 35 {python: "cp38", abi: "cp38", platform: "manylinux1_x86_64"}, 36 {python: "cp38", abi: "cp38", platform: "linux_arm64"}, 37 38 {python: "cp38", abi: "cp38", platform: "macosx_10_10_intel"}, 39 {python: "cp38", abi: "cp38", platform: "macosx_11_0_arm64"}, 40 41 {python: "cp38", abi: "cp38", platform: "win32"}, 42 {python: "cp38", abi: "cp38", platform: "win_amd64"} 43] 44 45wheel: < 46 name: "infra/python/wheels/six-py2_py3" 47 version: "version:1.15.0" 48> 49
