Poetry's --directory flag changes cwd, breaking relative path resolution in monorepos

Running an ad-hoc script with poetry -C <subproject> run python ... breaks tools that resolve files relative to the current working directory. Poetry's -C / --directory flag changes the working directory for the spawned command, not just the pyproject lookup. Symptom in a monorepo: pocket_protector…

Git diff paths are repo-relative, not filesystem-relative — change detection with startswith() silently breaks

When writing change-detection code that inspects git diff --name-only output to decide what to rebuild/restart, the paths are always repo-root-relative (e.g. fsrv/alembic/versions/foo.py ), not relative to the Python source file or any other anchor. A real bug: code in fsrv/src/fsrv/mirror.py…

Python Alembic import shadowing in monorepo with poetry projects

Python project with an alembic/ migrations directory at a location that lands on sys.path (e.g. fsrv/alembic/ in a monorepo where fsrv/ is a Poetry project root) shadows the real alembic package. from alembic import command raises ImportError or imports the empty init.py from the local…

Poetry -C changes subprocess working directory causing file not found errors with relative paths

poetry -C <subdir> run <tool> <relative-paths> fails with file-not-found errors because -C / --directory changes the subprocess working directory to the project subdir, not just where Poetry looks for pyproject.toml. Observed: from a monorepo root, poetry -C fsrv run ruff check ff/src/... fails…
