Timeout connections to unreachable hosts

[stchris]

I have a project which has, amongst others, a dependency on python-protobuf. This package in turn depends on python-dateutil which is hosted on readthedocs.org. Unfortunately pip install -r requirements.txt will try to reach dateutil.readthedocs.org, which is currently not reachable for me and this breaks the build.

I'd have expected the --timeout and/or --retries flags of pip to work on this as well, but it seems like they don't.

I've also tried --no-allow-external python-dateutil, but that didn't seem to work either.

Looking at https://github.com/pypa/pip/blob/develop/pip/index.py#L575 it might be that the latter doesn't work because there's a GET request going out before the check for allow_external is made. With some guidance I might help out with a Pull Request here.

What version of pip, and can you post the requirements.txt file?

Closing as unclear

seeing this bug, even with the most recent pip i ran into that issue when running pip install via ansible on a system that does not allow outbound http connections, pip would hang until some tcp timeout, retry n times and it would take up to 20 minutes before the failure would come back from ansible

Thanks for the clarification :)

I am having the same exact problem, despite upgrading pip to the latest version (pip 7.1.2)

Closing this, PyPI no longer allows linking to any external sites, --no-allow-external is gone, and the only way you'd contact RTD is by manually specifying it.
