Absorb a Windows Closed Pipe and Remove Read-Only Staged Objects in local_review - #2521
Merged
Merged
Conversation
…ocal_review On Windows a write to a pipe whose reader has exited raises OSError EINVAL rather than BrokenPipeError, so emit and main missed it and the interpreter's shutdown flush exited 120. closed_reader now recognizes both forms. worktree_states removed its throwaway object directory with ignore_errors, and Windows refuses to unlink git's read-only loose objects, so the directory and the staged content of every untracked file outlived the read. An rmtree handler now clears the read-only bit and retries. The tests give the coderabbit stand-in a batch wrapper on Windows, since Windows runs no shebang and resolves only a PATHEXT name. They make git's read-only loose object writable before deleting it, and run the piped case under the suite's own interpreter. Part of #2488. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

- Around line 1244-1251: Update the Windows wrapper construction in the test
setup to escape percent signs in the interpolated sys.executable path as batch
`%%`, and derive the Python script path from the wrapper’s own location using
`%~dpn0.py` instead of interpolating `script`.

…est Assertions (#2523) ## Summary Clears the rest of #2488, the 9 Windows failures left once #2521 cleared the `test_local_review` cluster. With both changes, `python3 -m unittest discover -s tests` passes on the Windows host from Git Bash. - **`spec/validate.py` writes UTF-8.** On Windows a piped stdout uses the ANSI code page, so the validator crashed reporting a registry name that code page cannot encode, a zero-width space for one, and wrote others, such as `ß`, in a form the suite's UTF-8 decode rejected. It now reconfigures both streams to UTF-8 at the top of `main`, through the same `utf8_console` helper `scripts/pr_review.py` already carries. On Linux the streams were already UTF-8, so CI output is unchanged. - **`test_release_guards` runs its guard script from a file.** The handoff read this failure as jq 1.8.2 rejecting `\S`, and that diagnosis is wrong: winget's jq 1.8.2 compiles the filter and gives every expected verdict when it receives it intact. The script went through `bash -c`, and Git Bash's own parse of the Windows command line collapses each doubled backslash inside a quoted argument, so the filter arrived holding an invalid escape and every value was refused. The test now writes the script to a temporary file and runs that, and `host_capability.bash_path`'s docstring records the trap for the next test. - **`test_host_gate`** asserted POSIX forms where Windows prints a backslash path, the PowerShell call operator, and `-Repo`. Each assertion now takes the host's form, and on Linux each expected string is still byte-identical to the literal it replaces. - **`test_docker_lint`** expected a forward-slash mount source from a native Windows `Path`. The expectation takes the separator from the host, and the doubled-quote escaping it pins is unchanged. Part of #2488, which the promotion pull request closes. ## Verification - On the Windows host from Git Bash, `test_spec_validate`, `test_host_gate`, `test_docker_lint`, and `test_release_guards` each pass, and the python-versions guard case runs rather than skips. - The full suite on this branch failed only in `test_local_review`, which #2521 fixes and which has since merged into `develop`. - `ruff format --check`, `ruff check`, and `mypy` pass. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>

## Summary Promotes three changes from `develop`, which together make `python3 -m unittest discover -s tests` pass on a Windows host from Git Bash. - #2521: two Windows defects in `scripts/local_review.py`, and the tests that exercise them. - A write to a closed pipe raises `OSError` with `EINVAL` on Windows rather than `BrokenPipeError`, so `status | head -0` exited 120 outside the 0/1/2 contract. `closed_reader` now recognizes both forms. - `worktree_states` left its throwaway object directory behind on Windows, holding the staged content of every untracked file, because `rmtree(ignore_errors=True)` could not unlink git's read-only loose objects. An `onexc` handler now clears the read-only bit and retries. - #2523: `spec/validate.py` writes its output as UTF-8 on every host, and a cp1252 regression case pins that on Linux CI too. Four Windows-shaped test assertions take the host's path, quoting, and flag forms. `test_release_guards` runs its guard script from a file, since Git Bash's parse of a Windows command line halves each doubled backslash inside a quoted `-c` argument, and `host_capability.bash_path` records that. - #2524: the jq carriage-return test's fixture now says `cataloged`, so the test fails when its stub is not reached. Closes #2488. Closes #2513. ## Verification - On the Windows host from Git Bash, `python3 -m unittest discover -s tests` at `develop`'s head ran 2245 tests and reported `OK`, where the round started from 15 failures and 10 errors. - Each change took a recorded local strict-review pass and a Copilot round on its first head. #2523's fix push is covered by an attested local pass. 🤖 Generated with [Claude Code](https://claude.com/claude-code)

A newclosed_readerrecognizes both forms, andmain's backstop now catchesOSError, sending any other one to the same boundary report as before through a smallcrashedhelper.worktree_statesremoved its throwaway object directory withignore_errors=True. Windows refuses to unlink git's read-only loose objects, so the directory, holding the staged content of every untracked file, outlived each read inside the git directory.
