* bpo-39999: Improve compatibility of the ast module. (GH-19056)Serhiy Storchaka2020-03-221-6/+8
| | | | | | | * Re-add removed classes Suite, slice, Param, AugLoad and AugStore. * Add docstrings for dummy classes. * Add docstrings for attribute aliases. * Set __module__ to "ast" instead of "_ast".
* bpo-40024: Add PyModule_AddType() helper function (GH-19088)Dong-hee Na2020-03-222-1/+14

* bpo-39652: Truncate the column name after '[' only if PARSE_COLNAMES is set. ↵Serhiy Storchaka2020-03-211-3/+4
| | | | (GH-18942)
* bpo-39946: Remove _PyThreadState_GetFrame (GH-19094)Victor Stinner2020-03-201-0/+4
| | | | | Remove _PyRuntime.getframe hook and remove _PyThreadState_GetFrame macro which was an alias to _PyRuntime.getframe. They were only exposed by the internal C API. Remove also PyThreadFrameGetter type.
* bpo-39947: Add PyThreadState_GetFrame() function (GH-19092)Victor Stinner2020-03-203-4/+21
| | | | Add PyThreadState_GetFrame() function: get the current frame of a Python thread state.
* bpo-40010: COMPUTE_EVAL_BREAKER() checks for subinterpreter (GH-19087)Victor Stinner2020-03-201-5/+7
| | | | | | | | | COMPUTE_EVAL_BREAKER() now also checks if the Python thread state belongs to the main interpreter. Don't break the evaluation loop if there are pending signals but the Python thread state it belongs to a subinterpeter. * Add _Py_IsMainThread() function. * Add _Py_ThreadCanHandleSignals() function.
* bpo-39797 Changes to socketserver.BaseServer's shutdown() method. (GH-18929)amaajemyfren2020-03-201-0/+2

* Fix "versionchanged" for pow named arguments (GH-19042)Mark Dickinson2020-03-191-1/+1
| | | The ability to use named arguments in "pow" was introduced in Python 3.8, not Python 3.9. See https://bugs.python.org/issue38237
* bpo-40010: Optimize signal handling in multithreaded applications (GH-19067)Victor Stinner2020-03-191-0/+10
| | | | | | | | | | | | | | | If a thread different than the main thread gets a signal, the bytecode evaluation loop is no longer interrupted at each bytecode instruction to check for pending signals which cannot be handled. Only the main thread of the main interpreter can handle signals. Previously, the bytecode evaluation loop was interrupted at each instruction until the main thread handles signals. Changes: * COMPUTE_EVAL_BREAKER() and SIGNAL_PENDING_SIGNALS() no longer set eval_breaker to 1 if the current thread cannot handle signals. * take_gil() now always recomputes eval_breaker.
* bpo-39984: Move pending calls to PyInterpreterState (GH-19066)Victor Stinner2020-03-192-0/+16
| | | | | | | | | | | | | | | | | If Py_AddPendingCall() is called in a subinterpreter, the function is now scheduled to be called from the subinterpreter, rather than being called from the main interpreter. Each subinterpreter now has its own list of scheduled calls. * Move pending and eval_breaker fields from _PyRuntimeState.ceval to PyInterpreterState.ceval. * new_interpreter() now calls _PyEval_InitThreads() to create pending calls lock. * Fix Py_AddPendingCall() for subinterpreters. It now calls _PyThreadState_GET() which works in a subinterpreter if the caller holds the GIL, and only falls back on PyGILState_GetThisThreadState() if _PyThreadState_GET() returns NULL.
* bpo-39988: Remove ast.AugLoad and ast.AugStore node classes. (GH-19038)Serhiy Storchaka2020-03-171-3/+4
|
* bpo-39824: module_traverse() don't call m_traverse if md_state=NULL (GH-18738)Victor Stinner2020-03-172-10/+45
| | | | | | | | | | | | | Extension modules: m_traverse, m_clear and m_free functions of PyModuleDef are no longer called if the module state was requested but is not allocated yet. This is the case immediately after the module is created and before the module is executed (Py_mod_exec function). More precisely, these functions are not called if m_size is greater than 0 and the module state (as returned by PyModule_GetState()) is NULL. Extension modules without module state (m_size <= 0) are not affected. Co-Authored-By: Petr Viktorin <encukou@gmail.com>
* bpo-39973: Fix the docs for PyObject_GenericSetDict() (GH-19026)Zackery Spytz2020-03-172-2/+3
| | | | PyObject_GenericSetDict() takes three arguments, not two.

* bpo-39509: Update HTTP status code to follow IANA (GH-18294)Dong-hee Na2020-03-142-0/+11
| | | Add status codes 103 EARLY_HINTS and 425 TOO_EARLY.
* bpo-39937: Improve suggestions for removal of getchildren and getiterator in ↵Rahul Kumaresan2020-03-141-4/+7

* bpo-39947: Add PyThreadState_GetInterpreter() (GH-18981)Victor Stinner2020-03-132-6/+16
| | | | Add PyThreadState_GetInterpreter(tstate): get the interpreter of a Python thread state.
* bpo-39947: Add PyInterpreterState_Get() function (GH-18979)Victor Stinner2020-03-132-0/+14
| | | | | | * Rename _PyInterpreterState_Get() to PyInterpreterState_Get() and move it the limited C API. * Add _PyInterpreterState_Get() alias to PyInterpreterState_Get() for backward compatibility with Python 3.8.
* bpo-36144: OrderedDict Union (PEP 584) (#18967)Brandt Bucher2020-03-131-0/+4

* bpo-35370: Add _PyEval_SetTrace() function (GH-18975)Victor Stinner2020-03-131-0/+5
| | | | | | | | | * sys.settrace(), sys.setprofile() and _lsprof.Profiler.enable() now properly report PySys_Audit() error if "sys.setprofile" or "sys.settrace" audit event is denied. * Add _PyEval_SetProfile() and _PyEval_SetTrace() function: similar to PyEval_SetProfile() and PyEval_SetTrace() but take a tstate parameter and return -1 on error. * Add _PyObject_FastCallTstate() function.
* bpo-38500: Add _PyInterpreterState_SetEvalFrameFunc() (GH-17340)Victor Stinner2020-03-122-0/+30
| | | | | | | | | | | | PyInterpreterState.eval_frame function now requires a tstate (Python thread state) parameter. Add private functions to the C API to get and set the frame evaluation function: * Add tstate parameter to _PyFrameEvalFunction function type. * Add _PyInterpreterState_GetEvalFrameFunc() and _PyInterpreterState_SetEvalFrameFunc() functions. * Add tstate parameter to _PyEval_EvalFrameDefault().

* tracemalloc: 'pretty top' example no longer changes the filename (GH-18903)Adam Johnson2020-03-101-3/+1
| | | | | I've used this recipe a couple times and the filename editing has always been less than useful and something I've removed. This is because many modules end up losing which package they are located in, e.g. `util/date.py`.
* bpo-34822: Simplify AST for subscription. (GH-9605)Serhiy Storchaka2020-03-103-37/+46
| | | | | | | | | * Remove the slice type. * Make Slice a kind of the expr type instead of the slice type. * Replace ExtSlice(slices) with Tuple(slices, Load()). * Replace Index(value) with a value itself. All non-terminal nodes in AST for expressions are now of the expr type.
* bpo-39869: Fix typo in 'Instance objects' section. (GH-18889)Antoine2020-03-101-1/+1

* bpo-1294959: Add sys.platlibdir attribute (GH-18381)Victor Stinner2020-03-102-0/+37
| | | | | | | | | | | | | Add --with-platlibdir option to the configure script: name of the platform-specific library directory, stored in the new sys.platlitdir attribute. It is used to build the path of platform-specific dynamic libraries and the path of the standard library. It is equal to "lib" on most platforms. On Fedora and SuSE, it is equal to "lib64" on 64-bit systems.

* bpo-39877: Deprecate PyEval_InitThreads() (GH-18892)Victor Stinner2020-03-102-5/+15
| | | | Deprecated PyEval_InitThreads() and PyEval_ThreadsInitialized(). Calling PyEval_InitThreads() now does nothing.
* bpo-28577: Special case added to IP v4 and v6 hosts for /32 and /128 ↵Pete Wicken2020-03-091-1/+6
| | | | | | networks (GH-18757) The `.hosts()` method now returns the single address present in a /32 or /128 network.
* bpo-36287: Make ast.dump() not output optional fields and attributes with ↵Serhiy Storchaka2020-03-091-99/+75
| | | | | | | default values. (GH-18843) The default values for optional fields and attributes of AST nodes are now set as class attributes (e.g. Constant.kind is set to None).

* bpo-38691: importlib ignores PYTHONCASEOK if -E is used (GH-18627)idomic2020-03-092-0/+6
| | | | | The importlib module now ignores the PYTHONCASEOK environment variable when the -E or -I command line options are being used.
* bpo-39852: IDLE 'Go to line' deletes selection, updates status (GH-18801)Terry Jan Reedy2020-03-081-1/+3
| | | | | | It appears standard that moving the text insert cursor away from a selection clears the selection. Clearing prevents accidental deletion of a possibly off-screen bit of text. The update is for Ln and Col on the status bar.
* fix typo: add space (GH-18853)Julin S2020-03-081-2/+2
| | | | Fix typo in cmdline.rst Add space between the `-m` option and the module name (`timeit`).

* bpo-36144: Update MappingProxyType with PEP 584's operators (#18814)Brandt Bucher2020-03-071-0/+5
| | | We make `|=` raise TypeError, since it would be surprising if `C.__dict__ |= {'x': 0}` silently did nothing, while `C.__dict__.update({'x': 0})` is an error.
* bpo-39702: Update the Language Reference (PEP 614) (GH-18802)Brandt Bucher2020-03-072-1/+15

* bpo-39882: Py_FatalError() logs the function name (GH-18819)Victor Stinner2020-03-061-0/+7
| | | | | | | | | | | | The Py_FatalError() function is replaced with a macro which logs automatically the name of the current function, unless the Py_LIMITED_API macro is defined. Changes: * Add _Py_FatalErrorFunc() function. * Remove the function name from the message of Py_FatalError() calls which included the function name. * Update tests.
* bpo-17422: slightly more precise language (GH-18682)Caleb Donovick2020-03-061-1/+1
