From cb66eb0deca1d5cd232f97c76a215ecaab958d30 Mon Sep 17 00:00:00 2001 From: Brett Cannon Date: Fri, 11 May 2012 12:58:42 -0400 Subject: Issue #13959: Deprecate imp.get_suffixes() for new attributes on importlib.machinery that provide the suffix details for import. The attributes were not put on imp so as to compartmentalize everything importlib needs for setting up imports in importlib.machinery. This also led to an indirect deprecation of inspect.getmoduleinfo() as it directly returned imp.get_suffix's returned tuple which no longer makes sense. --- Lib/importlib/_bootstrap.py | 24 +++++++++++++++--------- 1 file changed, 15 insertions(+), 9 deletions(-) (limited to 'Lib/importlib/_bootstrap.py') diff --git a/Lib/importlib/_bootstrap.py b/Lib/importlib/_bootstrap.py index 9952b067f1..ce23043665 100644 --- a/Lib/importlib/_bootstrap.py +++ b/Lib/importlib/_bootstrap.py @@ -163,11 +163,14 @@ def new_module(name): _PYCACHE = '__pycache__' -_SOURCE_SUFFIXES = ['.py'] # _setup() adds .pyw as needed. +SOURCE_SUFFIXES = ['.py'] # _setup() adds .pyw as needed. -_DEBUG_BYTECODE_SUFFIX = '.pyc' -_OPT_BYTECODE_SUFFIX = '.pyo' -_BYTECODE_SUFFIX = _DEBUG_BYTECODE_SUFFIX if __debug__ else _OPT_BYTECODE_SUFFIX +DEBUG_BYTECODE_SUFFIXES = ['.pyc'] +OPTIMIZED_BYTECODE_SUFFIXES = ['.pyo'] +if __debug__: + BYTECODE_SUFFIXES = DEBUG_BYTECODE_SUFFIXES +else: + BYTECODE_SUFFIXES = OPTIMIZED_BYTECODE_SUFFIXES def cache_from_source(path, debug_override=None): """Given the path to a .py file, return the path to its .pyc/.pyo file. @@ -181,10 +184,13 @@ def cache_from_source(path, debug_override=None): """ debug = __debug__ if debug_override is None else debug_override - suffix = _DEBUG_BYTECODE_SUFFIX if debug else _OPT_BYTECODE_SUFFIX + if debug: + suffixes = DEBUG_BYTECODE_SUFFIXES + else: + suffixes = OPTIMIZED_BYTECODE_SUFFIXES head, tail = _path_split(path) base_filename, sep, _ = tail.partition('.') - filename = ''.join([base_filename, sep, _TAG, suffix]) + filename = ''.join([base_filename, sep, _TAG, suffixes[0]]) return _path_join(head, _PYCACHE, filename) @@ -1147,15 +1153,15 @@ def _setup(sys_module, _imp_module): setattr(self_module, '_MAGIC_NUMBER', _imp_module.get_magic()) setattr(self_module, '_TAG', _imp.get_tag()) if builtin_os == 'nt': - _SOURCE_SUFFIXES.append('.pyw') + SOURCE_SUFFIXES.append('.pyw') def _install(sys_module, _imp_module): """Install importlib as the implementation of import.""" _setup(sys_module, _imp_module) extensions = ExtensionFileLoader, _imp_module.extension_suffixes(), False - source = SourceFileLoader, _SOURCE_SUFFIXES, True - bytecode = SourcelessFileLoader, [_BYTECODE_SUFFIX], True + source = SourceFileLoader, SOURCE_SUFFIXES, True + bytecode = SourcelessFileLoader, BYTECODE_SUFFIXES, True supported_loaders = [extensions, source, bytecode] sys.path_hooks.extend([FileFinder.path_hook(*supported_loaders)]) sys.meta_path.extend([BuiltinImporter, FrozenImporter, PathFinder]) -- cgit v1.2.1
