Thank you very much for reporting this! However, I can reproduce this neither the latest release 20.2.1 nor the current master ee4371c. Furthermore, there seems to be a typo in version you listed, 5a61475 is part of GH-6236 which was merged on 2019-02-05 and was released as pip 19.0.2. The traceback you provided from forcing reinstalling setuptools and pip suggests that the implementation of the wheel over HTTP range requests thing got some segment merging done wrong, but it would be difficult to debug without failure occurring. It would be really nice if you can additionally see if the crash is reproducible on pip 20.2.0 and 20.2.1. |

Thank you @akaihola, this is really helpful, I'll investigate this ASAP. Until then, I want to note that the |

The problem seem to be with incorrect (?) caching of range responses (please have my apologies, @akaihola, for putting you through creating a container for this—I have diff --git a/src/pip/_internal/network/lazy_wheel.py b/src/pip/_internal/network/lazy_wheel.py

Environment
Description
Force-reinstalling a cached package causes pip to fail if
use-feature = 2020-resolver fast-depsboth are enabled.I saw this behavior with Black, pip itself, wheel and setuptools. The example below is for Black.
If only either
2020-resolverorfast-depsis enabled, everything works correctly.Expected behavior
The package should be reinstalled successfully.
How to Reproduce
pip config set --site global.use-feature "2020-resolver fast-deps"--force-reinstalloptionOutput
The final error for the other packages I tried was:
