'size' is a requested size for the test (in arbitrary, test-interpreted units.) 'memuse' is the number of bytes per unit for the test, or a good estimate of it. For example, a test that needs two byte buffers, of 4 GiB each, could be decorated with @bigmemtest(size=_4G, memuse=2). The 'size' argument is normally passed to the decorated test method as an extra argument. If 'dry_run' is true, the value passed to the test method may be less than the requested value. If 'dry_run' is false, it means the test doesn't support dummy runs when -M is not specified. c s fdd_ _S )Nc s j }j}ts d}n|}ts s"t|| k r"td|| d tr=tr=t tdj|| d d t }| nd }z | |W |rL| S S |rT| w w )Ni 'not enough memory: %.1fG minimum needed @z* ... expected peak memory use: {peak:.1f}G)peak) r memuser rf ry r r r r r r )r[ r r maxsizewatchdog)dry_runrc r rP rQ r a s6 z.bigmemtest.<locals>.decorator.<locals>.wrapper)r r rb r r r rc r rQ r ` s z bigmemtest.<locals>.decoratorrP )r r r r rP r rQ r S s !r c r )z0Decorator for tests that fill the address space.c s< t tk rtdkrt dkrtdtdtd | S )Nl l z-not enough memory: try a 32-bit build insteadr r )r r rf ry r^ rb rP rQ r s z!bigaddrspacetest.<locals>.wrapperrP r rP rb rQ r s r c @ s e Zd Zdd ZdS )r c C s t }|| |S rU )rf TestResult)r[ r r rP rP rQ run zBasicTestRunner.runN)rL rM rN r rP rP rP rQ r s r c C ra rU rP )rz rP rP rQ _id r c C s6 | dkr t s tt jS t| rtS td| S )Nr z resource {0!r} is not enabled)r rf r r r r r r rP rP rQ requires_resource s r c C s t dd| S )z9 Decorator for tests only applicable on CPython.

The module's public names (its API) are detected automatically based on whether they match the public name convention and were defined in 'module'. The 'name_of_module' argument can specify (as a string or tuple thereof) what module(s) an API could be defined in in order to be detected as a public API. One case for this is when 'module' imports part of its public API from other modules, possibly a C backend (like 'csv' and its '_csv'). The 'extra' argument can be a set of names that wouldn't otherwise be automatically detected as "public", like objects without a proper '__module__' attribute. If provided, it will be added to the automatically detected ones. The 'not_exported' argument can be a set of names that must not be treated as part of the public API even though their names indicate otherwise. Usage: import bar import foo import unittest from test import support class MiscTestCase(unittest.TestCase): def test__all__(self): support.check__all__(self, foo) class OtherTestCase(unittest.TestCase): def test__all__(self): extra = {'BAR_CONST', 'FOO_CONST'} not_exported = {'baz'} # Undocumented name. # bar imports part of its API from _bar. support.check__all__(self, bar, ('bar', '_bar'), extra=extra, not_exported=not_exported) Nr rM ) rL r r r r r rw r types ModuleTypeaddassertCountEqual__all__) test_caser0 name_of_moduleextra not_exportedexpectedr{ rz rP rP rQ r( s" ) r( c C s zdd l }W n ty Y d S w ||j|jB |jB |jB t|drG|j|j |j fD ]}| r@| ||j | ||j q-| |d q-d S d S )Nr CrtSetReportMode)msvcrtr SetErrorModeSEM_FAILCRITICALERRORSSEM_NOALIGNMENTFAULTEXCEPTSEM_NOGPFAULTERRORBOXSEM_NOOPENFILEERRORBOXr CRT_WARN CRT_ERROR CRT_ASSERTr CRTDBG_MODE_FILECrtSetReportFileCRTDBG_FILE_STDERR)r r r rP rP rQ suppress_msvcrt_asserts s( r c @ s( e Zd ZdZdZdZdd Zdd ZdS )r: zTry to prevent a crash report from popping up.

Storing the exception value (cm.unraisable.exc_value) creates a reference cycle. The reference cycle is broken explicitly when the context manager exits.
