* bpo-30876: Relative import from unloaded package now reimports the package ↵Serhiy Storchaka2017-07-121-7/+0
| | | | | | | | | (#2639) instead of failing with SystemError. Relative import from non-package now fails with ImportError rather than SystemError.
* bpo-30891: Fix importlib _find_and_load() race condition (#2646)Victor Stinner2017-07-101-4/+0
| | | | | | * Rewrite importlib _get_module_lock(): it is now responsible to hold the imp lock directly. * _find_and_load() now holds the module lock to check if name is in sys.modules to prevent a race condition
* bpo-30814: Fixed a race condition when import a submodule from a package. ↵Serhiy Storchaka2017-07-061-16/+1

* bpo-30626: Fix error handling in PyImport_Import(). (#2103)Serhiy Storchaka2017-06-151-2/+6
| | | | In rare circumstances PyImport_Import() could return NULL without raising an error.

* bpo-6532: Make the thread id an unsigned integer. (#781)Serhiy Storchaka2017-03-231-10/+11
| | | | | | | | | | | * bpo-6532: Make the thread id an unsigned integer. From C API side the type of results of PyThread_start_new_thread() and PyThread_get_thread_ident(), the id parameter of PyThreadState_SetAsyncExc(), and the thread_id field of PyThreadState changed from "long" to "unsigned long". * Restore a check in thread_get_ident().

* Use _PyObject_CallMethodIdObjArgs()Victor Stinner2016-12-091-1/+1
| | | | | | | | | Issue #28915: Replace _PyObject_CallMethodId() with _PyObject_CallMethodIdObjArgs() in various modules when the format string was only made of "O" formats, PyObject* arguments. _PyObject_CallMethodIdObjArgs() avoids the creation of a temporary tuple and doesn't have to parse a format string.
* Backed out changeset b9c9691c72c5Victor Stinner2016-12-041-1/+1
| | | | | | Issue #28858: The change b9c9691c72c5 introduced a regression. It seems like _PyObject_CallArg1() uses more stack memory than PyObject_CallFunctionObjArgs().
* Replace PyObject_CallFunctionObjArgs() with fastcallVictor Stinner2016-12-011-1/+1
| | | | | | | | | | | | | | * PyObject_CallFunctionObjArgs(func, NULL) => _PyObject_CallNoArg(func) * PyObject_CallFunctionObjArgs(func, arg, NULL) => _PyObject_CallArg1(func, arg) PyObject_CallFunctionObjArgs() allocates 40 bytes on the C stack and requires extra work to "parse" C arguments to build a C array of PyObject*. _PyObject_CallNoArg() and _PyObject_CallArg1() are simpler and don't allocate memory on the C stack. This change is part of the fastcall project. The change on listsort() is related to the issue #23507.

* | Issue #25791: Warn when __package__ != __spec__.parent.Brett Cannon2016-01-221-39/+58
| | | | | | | | | | | | | | | | | | In a previous change, __spec__.parent was prioritized over __package__. That is a backwards-compatibility break, but we do eventually want __spec__ to be the ground truth for module details. So this change reverts the change in semantics and instead raises an ImportWarning when __package__ != __spec__.parent to give people time to adjust to using spec objects.

| | | | | | | | | | | | | | | | not defined for a relative import. This is the start of work to try and clean up import semantics to rely more on a module's spec than on the myriad attributes that get set on a module. Thanks to Rose Ames for the patch.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Known limitations of the current implementation: - documentation changes are incomplete - there's a reference leak I haven't tracked down yet The leak is most visible by running: ./python -m test -R3:3 test_importlib However, you can also see it by running: ./python -X showrefcount Importing the array or _testmultiphase modules, and then deleting them from both sys.modules and the local namespace shows significant increases in the total number of active references each cycle. By contrast, with _testcapi (which continues to use single-phase initialisation) the global refcounts stabilise after a couple of cycles.
