#19957 Expose pex's `--check` validation Issue created by huonw Is your feature request related to a problem? Please describe. In 2.1.148 (pex-tool/pex#2247 / pex-tool/pex#2253), PEX adds support for

--check=...

to give build-time warnings/errors about

--layout=zipapp

PEXes that are likely to not be able to be loaded by a Python interpreter, e.g. so many files or large enough to require "ZIP64" extensions, which

zipimport

doesn't handle (python/cpython#77140). This likely affects large PEXes including machine learning packages like PyTorch. Describe the solution you'd like For the

pex_binary

target: • ensure that any warnings are exposed • consider providing a pass-through

check

option somehow Describe alternatives you've considered A general mechanism for showing warnings Additional context N/A pantsbuild/pants
