"""Basic test of the frozen module (source is in Python/frozen.c)."""
|
||
|
|
|
||
|
|
# The Python/frozen.c source code contains a marshalled Python module
|
||
|
|
# and therefore depends on the marshal format as well as the bytecode
|
||
|
|
# format. If those formats have been changed then frozen.c needs to be
|
||
|
|
# updated.
|
||
|
|
#
|
||
|
|
# The test_importlib also tests this module but because those tests
|
||
|
|
# are much more complicated, it might be unclear why they are failing.
|
||
|
|
# Invalid marshalled data in frozen.c could case the interpreter to
|
||
|
|
# crash when __hello__ is imported.
