Error for `uv pip compile scripts/requirements/jupyter.in` without internet: **Before** ``` error: error sending request for url (https://pypi.org/simple/jupyter/): error trying to connect: dns error: failed to lookup address information: No such host is known. (os error 11001) Caused by: error trying to connect: dns error: failed to lookup address information: No such host is known. (os error 11001) Caused by: dns error: failed to lookup address information: No such host is known. (os error 11001) Caused by: failed to lookup address information: No such host is known. (os error 11001) ``` **After** ``` error: Could not connect, are you offline? Caused by: error sending request for url (https://pypi.org/simple/django/): error trying to connect: dns error: failed to lookup address information: Temporary failure in name resolution Caused by: error trying to connect: dns error: failed to lookup address information: Temporary failure in name resolution Caused by: dns error: failed to lookup address information: Temporary failure in name resolution Caused by: failed to lookup address information: Temporary failure in name resolution ``` On linux, it would be "Temporary failure in name resolution" instead of "No such host is known. (os error 11001)". The implementation checks for "dne error" stringly as hyper errors are opaque. The danger is that this breaks with a hyper update. We still get the complete error trace since reqwest eagerly inlines errors (https://github.com/seanmonstar/reqwest/issues/2147). No test since i wouldn't know how to simulate this in cargo test. Fixes #1971 |
