From 109717457edbf49421af3848ea26e26fff567289 Mon Sep 17 00:00:00 2001 From: Jim Mussared Date: Fri, 2 Jun 2023 15:23:23 +1000 Subject: [PATCH] tests/run-multitests.py: Don't allow imports from the cwd. Make tests run in an isolated environment (i.e. `import io` would otherwise get the `tests/io` directory). This work was funded through GitHub Sponsors.
