* [3.5] Backport bpo-30876 (GH-2639), bpo-18018 and bpo-26367. (#2677)Serhiy Storchaka2017-07-231-5/+3
| | | | | | | | | | | | | | | | * bpo-30876: Relative import from unloaded package now reimports the package instead of failing with SystemError. Relative import from non-package now fails with ImportError rather than SystemError. (cherry picked from commit 8a9cd20edca7d01b68292036029ae3735ce65edd) * bpo-18018: Import raises ImportError instead of SystemError if a relative import is attempted without a known parent package. * bpo-26367: importlib.__init__() raises ImportError like builtins.__import__() when ``level`` is specified but without an accompanying package specified.
* [3.5] bpo-30626: Fix error handling in PyImport_Import(). (GH-2103) (#2222)Serhiy Storchaka2017-06-151-2/+6
| | | | | In rare circumstances PyImport_Import() could return NULL without raising an error. (cherry picked from commit 145541c)
* [3.5] bpo-29537: Tolerate legacy invalid bytecode (#169)Nick Coghlan2017-03-081-1/+9
| | | | | | | | | | | | | | | | | | bpo-27286 fixed a problem where BUILD_MAP_UNPACK_WITH_CALL could be emitted with an incorrect oparg value, causing the eval loop to access the wrong stack entry when attempting to read the function name. The associated magic number change caused significant problems when attempting to upgrade to 3.5.3 for anyone that relies on pre-cached bytecode remaining valid across maintenance releases. This patch restores the ability to import legacy bytecode generated by 3.5.0, 3.5.1 or 3.5.2, and modifies the eval loop to avoid any harmful consequences from the potentially malformed legacy bytecode. Original import patch by Petr Viktorin, eval loop patch by Serhiy Storchaka, and tests and integration by Nick Coghlan.

* | PEP 489: Multi-phase extension module initializationNick Coghlan2015-05-231-66/+123
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | Issue #20530: Argument Clinic's signature format has been revised again.Larry Hastings2014-02-091-24/+48
| | | | | | | | | | | | | | The new syntax is highly human readable while still preventing false positives. The syntax also extends Python syntax to denote "self" and positional-only parameters, allowing inspect.Signature objects to be totally accurate for all supported builtins in Python 3.4.

"self" parameters are also explicitly marked, allowing inspect.Signature() to authoritatively detect (and skip) said parameters.
