Fast-deps: bad interaction with Artifactory leading to zipfile.BadZipFile

See original GitHub issue

What did you want to do? Trying to install Cython using the experimental features.

Command line:

virtualenv -p python3.7 env
source env/bin/activate
pip install -U pip
pip install --use-feature=2020-resolver --use-feature=fast-deps -v cython

This works correctly on my home linux computer, but fails at work where we have the following /etc/pip.conf:

[global]
cert = /etc/pki/tls/cert.pem
no-cache-dir = false
index-url = https://artifactory.our-organization.com/artifactory/api/pypi/python-virtual-repo/simple
index = https://artifactory.our-organization.com/artifactory/api/pypi/python-virtual-repo/simple

It also works in both places when I keep 2020-resolver but omit fast-deps.

The same problem is present on master

Output This is the relevant part of the output from pip -v, with pip f17c1d6d3bf4b4ee8b7b0e669c449b9cd86e94f6 installed:

Additional information

Happy to try versions from pull requests if that’s helpful. I might also be smart enough to set up a mitmproxy to record the HTTP interaction, but I’m not completely sure.

Howdy, looks like a bug was filed against warehouse (PyPI) regarding this.

I wanted to drop in to note that the CDN for PyPI files (files.pythonhosted.org) has continuously supported Range requests since its inception.

The confusion seems to be around some copy pasta curl commands being used to test the functionality.

Our CDN does not respond perfectly to Range requests when they come in as a HEAD request, but does for valid GET requests with a Range header.

Note that many of the examples in this thread include the -I parameter to curl leading to a HEAD request.

Because our CDN fetches the full file to cache at edge before responding to Range GET requests, the HEAD is the response for the full object, always.

I would certainly hope removing old resolver would be pushed out into horizon until one or more of these speedups is in place in both Warehouse and downstream mirrors. That may take years for server features.
