* bpo-28411: Support other mappings in PyInterpreterState.modules. (#3593)Eric Snow2017-09-151-6/+1
| | | | | 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.
* bpo-31404: Revert "remove modules from Py_InterpreterState (#1638)" (#3565)Eric Snow2017-09-141-1/+4
| | | 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.

* bpo-30860: Consolidate stateful runtime globals. (#3397)Eric Snow2017-09-081-41/+39
| | | | | | | * group the (stateful) runtime globals into various topical structs * consolidate the topical structs under a single top-level _PyRuntimeState struct * add a check-c-globals.py script that helps identify runtime globals Other globals are excluded (see globals.txt and check-c-globals.py).

* Issue #20185: Convert _warnings.warn() to Argument ClinicVictor Stinner2016-12-091-16/+21
| | | | Fix warn_explicit(): interpret source=None as source=NULL.
* 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.
* Issue #28858: Remove _PyObject_CallArg1() macroVictor Stinner2016-12-051-1/+1
| | | | | | | | | | | Replace _PyObject_CallArg1(func, arg) with PyObject_CallFunctionObjArgs(func, arg, NULL) Using the _PyObject_CallArg1() macro increases the usage of the C stack, which was unexpected and unwanted. PyObject_CallFunctionObjArgs() doesn't have this issue.
* 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_CallFunction() with fastcallVictor Stinner2016-12-011-1/+1
| | | | | | | | | | | | | | | | | Replace PyObject_CallFunction(func, "O", arg) and PyObject_CallFunction(func, "O", arg, NULL) with _PyObject_CallArg1(func, arg) Replace PyObject_CallFunction(func, NULL) with _PyObject_CallNoArg(func) _PyObject_CallNoArg() and _PyObject_CallArg1() are simpler and don't allocate memory on the C stack.
* 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.

* | Add _showwarnmsg() and _formatwarnmsg() to warningsVictor Stinner2016-03-181-25/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | Issue #26568: add new _showwarnmsg() and _formatwarnmsg() functions to the warnings module. The C function warn_explicit() now calls warnings._showwarnmsg() with a warnings.WarningMessage as parameter, instead of calling warnings.showwarning() with multiple parameters. _showwarnmsg() calls warnings.showwarning() if warnings.showwarning() was replaced. Same for _formatwarnmsg(): call warnings.formatwarning() if it was replaced.
