"""Tests for the --data-dir / --cache-dir override mechanism in d360.
|
|
|
|
D360 has 5 entry scripts (``fetch_dc.py``, ``assemble_dc.py``, ``render_dc.py``,
|
|
``resolve_session.py``, ``discover_sessions.py``) — each invokes the shared
|
|
``_shared.cli_override.apply_overrides()`` helper. Three things must be true
|
|
after ``--data-dir <path>`` is parsed:
|
|
|
|
1. ``paths.DATA_ROOT`` points at the override.
|
|
2. ``config.DATA_ROOT`` points at the override (re-export).
|
|
3. The entry script's local ``DATA_ROOT`` (captured via
|
|
``from config import DATA_ROOT``) points at the override.
|
|
|
|
Without all three, callers reading ``DATA_ROOT`` from the entry script see
|
|
stale defaults.
