demandimport: avoid infinite recursion at actual module importing (issue5304) Before this patch, importing C module on Windows environment causes infinite recursion call, if py2exe is used with -b2 option. At importing C module "a.b", extra hooking by zipextimporter of py2exe causes: 0. assumption before accessing "b" of "a": - built-in module object is created for "a", (= "a" is actually imported) - _demandmod is created for "a.b" as a proxy object, and (= "a.b" is not yet imported) - an attribute "b" of "a" is initialized by the latter 1. invocation of __import__ via _hgextimport() in _demandmod._load() for "a.b" implies _demandimport() for "a.b" This is unintentional, because _demandmod might be returned by _hgextimport() instead of built-in module object. 2. _demandimport() at (1) is invoked with not context of "a", but context of zipextimporter Just after invocation of _hgextimport() in _demandimport(), an attribute "b" of the built-in module object for "a" is still bound to the proxy object for "a.b", because context of "a" isn't updated by actual importing "a.b". even though the built-in module object for "a.b" already appears in sys.modules. Therefore, chainmodules() returns _demandmod for "a.b", which is gotten from the attribute "b" of "a". 3. processfromitem() on "a.b" causes _demandmod._load() for "a.b" again _demandimport() takes context of "a" in this case. Therefore, attributes below are bound to built-in module object for "a.b", as expected: - "b" of built-in module object for "a" - _module of _demandmod for "a.b" 4. but _demandimport() invoked at (1) returns _demandmod object because _demandimport() just returns the object returned by chainmodules() at (3) above. 5. then, _demandmod._load() causes infinite recursion call _demandimport() returns _demandmod for "a.b", and it is "self" at _demandmod._load(). To avoid infinite recursion at actual module importing, this patch uses self._module, if _hgextimport() returns _demandmod itself. If _demandmod._module isn't yet bound at this point, execution should be aborted, because actual importing failed. In this patch, _demandmod._module is examined not on _demandimport() side, but on _demandmod._load() side, because: - the former has some exit points - only the latter uses _hgextimport(), except for _demandimport() BTW, this issue occurs only in the code path for non .py/.pyc files in zipextimporter (strictly speaking, in _memimporter) of py2exe. Even if zipextimporter is enabled, .py/.pyc files are handled by zipimporter, and it doesn't imply unintentional _demandimport() at invocation of __import__ via _hgextimport().
