Oren Milman 6db7033192 bpo-31492: Fix assertion failures in case of a module with a bad __name__ attribute. (#3620) 2017-09-19 14:23:01 +03:00
Serhiy Storchaka 4ab46d7949 bpo-31497: Add private helper _PyType_Name(). (#3630)
This function returns the last component of tp_name after a dot.
Returns tp_name itself if it doesn't contain a dot.

Eric Snow 3f9eee6eb4 bpo-28411: Support other mappings in PyInterpreterState.modules. (#3593)
The concrete PyDict_* API is used to interact with PyInterpreterState.modules in a number of places. This isn't compatible with all dict subclasses, nor with other Mapping implementations. This patch switches the concrete API usage to the corresponding abstract API calls.

We also add a PyImport_GetModule() function (and some other helpers) to reduce a bunch of code duplication.

Barry Warsaw b2e5794870 bpo-31338 (#3374)
* Add Py_UNREACHABLE() as an alias to abort().
* Use Py_UNREACHABLE() instead of assert(0)
* Convert more unreachable code to use Py_UNREACHABLE()
* Document Py_UNREACHABLE() and a few other macros.

Eric Snow d393c1b227 bpo-28411: Isolate PyInterpreterState.modules (#3575)
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.

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.

parts. We want to continue to allow IEEE 754 doubles larger than FLT_MAX to be
rounded into finite floats. Tests were added to very this behavior.

INADA Naoki aa289a59ff bpo-29548: Recommend PyObject_Call APIs over PyEval_Call APIs. (GH-75)
PyEval_Call* APIs are not documented and they doesn't respect PY_SSIZE_T_CLEAN.
So add comment block which recommends PyObject_Call* APIs to ceval.h.

This commit also changes PyEval_CallMethod and PyEval_CallFunction
implementation same to PyObject_CallMethod and PyObject_CallFunction
to reduce future maintenance cost.  Optimization to avoid temporary
tuple are copied too.

PyEval_CallFunction(callable, "i", (int)i) now calls callable(i) instead of
raising TypeError.  But accepting this edge case is backward compatible.
