On Windows os.open() defaults to text mode, so os.write() of preserved config bytes containing \r\n was translated to \r\r\n, corrupting the staged backup and failing the retry-restore regression test. Add O_BINARY (0 on POSIX) to the staging file open flags. Assisted-by: GitHub Copilot (model: Claude Opus 4.8, autonomous) Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com>

The .extensionignore loader can raise ValidationError (invalid UTF-8) or OSError. Previously it ran after dest_dir was removed, so such a failure left the kept config only in the hidden staging directory rather than its documented location. Load/validate it before the rmtree so every post-deletion failure path restores the config. Adds a regression test.

Bug fix — reinstall-overwrites-kept-config
Proposed fix for issue #3427, applying the remediation from the bug assessment.
Verdict: Valid · Severity: medium
Summary
When
specify extension remove <ext> --keep-configis used, the extension is unregistered but its*-config.ymlfiles survive in the extension directory. A subsequent plainspecify extension add <ext>unconditionally deleted that directory before copying the fresh extension in, silently discarding the preserved config. The fix rescues those stranded config files into memory before thermtreeand writes them back aftercopytree, so user-customized values always win over the packaged defaults.Changes

None. The implementation follows the preferred remediation exactly as described.
Risks & Review Notes
not self.registry.is_installed(manifest.id)guard ensures we only rescue configs when the extension is genuinely unregistered, avoiding picking up stale files from a different install.shutil.copytree, so packaged defaults are always superseded by the user's values — no risk of defaults silently winning.install_from_zip()delegates toinstall_from_directory(), so it is covered without additional changes.install_from_directory().Refs #3427 · cc
