"""
Test transitional symbol migration functionality for all Kconfig types.
This tests that:
- OLD_* options in existing .config cause NEW_* options to be set
- OLD_* options are not written to the new .config file
- NEW_* options appear in the new .config file with correct values
- NEW_* options with defaults from transitional symbols are not prompted
- All Kconfig types work correctly: bool, tristate, string, hex, int
- User-set NEW values take precedence over conflicting OLD transitional values
"""
def test(conf):
# Run olddefconfig to process the migration with the initial config
assert conf.olddefconfig(dot_config='initial_config') == 0
# Check that the configuration matches expected output
assert conf.config_contains('expected_config')
# Test oldconfig to ensure symbols with transitional defaults are not prompted
assert conf.oldconfig(dot_config='initial_config', in_keys='n\n') == 0
# Except for when conditional default evaluates to 'no'
assert conf.stdout_contains('expected_stdout')
Annotation
- Atlas domain: Support Tooling And Documentation / scripts.
- Implementation status: atlas-only.
Implementation Notes
- This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
- Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
- Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
