* [3.7] Fix misleading mentions of tp_size in comments. (GH-9136)Benjamin Peterson2018-09-101-2/+2
| | | | | | | Many type object initializations labeled a field "tp_size" in the comment, but the name of that field is tp_basicsize.. (cherry picked from commit 0e0bc4e221f592f305d335faf5f8046484eb9238) Co-authored-by: Peter Eisentraut <peter@eisentraut.org>
* bpo-32374: m_traverse may be called with m_state=NULL (GH-5140)Miss Islington (bot)2018-03-161-0/+21
| | | | | | | | Multi-phase initialized modules allow m_traverse to be called while the module is still being initialized, so module authors may need to account for that. (cherry picked from commit c2b0b12d1a137ada1023ab7c10b8d9a0249d95f9) Co-authored-by: Marcel Plch <gmarcel.plch@gmail.com>

* bpo-28411: Isolate PyInterpreterState.modules (#3575)Eric Snow2017-09-141-3/+9
| | | | | A bunch of code currently uses PyInterpreterState.modules directly instead of PyImport_GetModuleDict(). This complicates efforts to make changes relative to sys.modules. This patch switches to using PyImport_GetModuleDict() uniformly. Also, a number of related uses of sys.modules are updated for uniformity for the same reason. Note that this code was already reviewed and merged as part of #1638. I reverted that and am now splitting it up into more focused parts.
* bpo-31404: Revert "remove modules from Py_InterpreterState (#1638)" (#3565)Eric Snow2017-09-131-9/+3
| | | PR #1638, for bpo-28411, causes problems in some (very) edge cases. Until that gets sorted out, we're reverting the merge. PR #3506, a fix on top of #1638, is also getting reverted.

* PEP 489: Multi-phase extension module initializationNick Coghlan2015-05-231-52/+283
| | | | | | | | | | | | | | | | | | | | | | | 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.

|/ | | | | | | | | | | | | | | | | attributes to None. The long-term goal is for people to be able to rely on these attributes existing and checking for None to see if they have been set. Since import itself sets these attributes when a loader does not the only instances when the attributes are None are from someone overloading __import__() and not using a loader or someone creating a module from scratch. This patch also unifies module initialization. Before you could have different attributes with default values depending on how the module object was created. Now the only way to not get the same default set of attributes is to circumvent initialization by calling ModuleType.__new__() directly.
