From 568279624ed087439fe307cbdf6f19d07bd55f7b Mon Sep 17 00:00:00 2001 From: flupkede Date: Tue, 2 Jun 2026 21:55:31 +0200 Subject: [PATCH 1/2] fix: rename_retry helper for Windows flaky tests in repos.rs On Windows, git subprocesses spawned by init_git_remote keep file handles open briefly after the process exits, causing std::fs::rename and std::fs::remove_dir_all to fail with "Access is denied" under parallel test load. Fixes: - Add rename_retry() test helper that retries with exponential back-off (up to 10 attempts, 20-200ms delays) - Replace all 7 std::fs::rename(...).unwrap() calls in the repos test module with rename_retry() - Change remove_dir_all(...).unwrap() in try_relocate_none_when_ambiguous to let _ = ... (the assertion holds either way) Verified stable: 3 consecutive full-suite runs with 432 passed, 0 failed.
