* bpo-34602: Avoid failures setting macOS stack resource limit (GH-13011)Ned Deily2019-04-293-12/+3
| | | | | | | | | | | | Under some conditions the earlier fix for bpo-18075, "Infinite recursion tests triggering a segfault on Mac OS X", now causes failures on macOS when attempting to change stack limit with resource.setrlimit resource.RLIMIT_STACK, like regrtest does when running the test suite. The reverted change had specified a non-default stack size when linking the python executable on macOS. As of macOS 10.14.4, the previous code causes a hard failure when running tests, although similar failures had been seen under some conditions under some earlier systems. For now, revert the original change and resume using the default stack size when linking the interpreter.

* bpo-36025: Fix PyDate_FromTimestamp API (GH-11922)Paul Ganssle2019-04-274-2/+126
| | | | | | | | | | | | | In the process of converting the date.fromtimestamp function to use argument clinic in GH-8535, the C API for PyDate_FromTimestamp was inadvertently changed to expect a timestamp object rather than an argument tuple. This PR fixes this backwards-incompatible change by adding a new wrapper function for the C API function that unwraps the argument tuple and passes it to the underlying function. This PR also adds tests for both PyDate_FromTimestamp and PyDateTime_FromTimestamp to prevent any further regressions.
* bpo-36722: Style and grammar edits for ABI news entries (GH-12979)Paul Ganssle2019-04-274-22/+24

* Syntax highlight IDLE html doc code example. (GH-12981)Terry Jan Reedy2019-04-272-29/+25
| | | The new markup is currently ignored by IDLE's tk doc display.
* bpo-36722: Don't define ALT_SOABI for Py_TRACE_REFS build (GH-12973)Victor Stinner2019-04-263-6/+14
| | | | Py_TRACE_REFS ABI is incompatible with release and debug (Py_DEBUG) ABI.
* bpo-36722: Add What's New entry for debug ABI (GH-12957)Victor Stinner2019-04-261-0/+24

* bpo-21536: Revert Makefile change on python-config (GH-12971)Victor Stinner2019-04-261-1/+3
| | | | Misc/python-config.sh lives in the build directory, not in the source directory.

|
* bpo-36733: Fix PYTHONPATH for make regen-add (GH-12969)Victor Stinner2019-04-261-2/+2
| | | | Add PYTHONPATH=$(srcdir) to run $(PYTHON_FOR_REGEN) -m Parser.pgen, so it's possible to build Python from a different directory.
* bpo-36356: pymain_exit_error() only call pymain_free() for exit (GH-12968)Victor Stinner2019-04-263-3/+10
| | | Add _Py_INIT_HAS_EXITCODE() macro.
* bpo-36719: regrtest closes explicitly WindowsLoadTracker (GH-12965)Victor Stinner2019-04-262-14/+29
| | | | Regrtest.finalize() now closes explicitly the WindowsLoadTracker instance.
* bpo-36719: Fix regrtest re-run (GH-12964)Victor Stinner2019-04-263-14/+35
| | | | | Properly handle a test which fail but then pass. Add test_rerun_success() unit test.
* bpo-36719: regrtest always detect uncollectable objects (GH-12951)Victor Stinner2019-04-265-69/+66
| | | | | | | regrtest now always detects uncollectable objects. Previously, the check was only enabled by --findleaks. The check now also works with -jN/--multiprocess N. --findleaks becomes a deprecated alias to --fail-env-changed.

* bpo-36725: Refactor regrtest multiprocessing code (GH-12961)Victor Stinner2019-04-265-152/+205
| | | | | | | | | | | | | | | | Rewrite run_tests_multiprocess() function as a new MultiprocessRunner class with multiple methods to better report errors and stop immediately when needed. Changes: * Worker processes are now killed immediately if tests are interrupted or if a test does crash (CHILD_ERROR): worker processes are killed. * Rewrite how errors in a worker thread are reported to the main thread. No longer ignore BaseException or parsing errors silently. * Remove 'finished' variable: use worker.is_alive() instead * Always compute omitted tests. Add Regrtest.get_executed() method.
* bpo-36724: Add _PyWarnings_Fini() (#12963)Victor Stinner2019-04-263-17/+35
| | | | | | | | | | Py_FinalizeEx() now clears _PyRuntime.warnings variables and _PyRuntime.exitfuncs. Changes: * Add _PyWarnings_Fini(): called by Py_FinalizeEx() * call_ll_exitfuncs() now clears _PyRuntime.exitfuncs while iterating on it (on backward order).
* bpo-36710: Fix compiler warning on PyThreadState_Delete() (GH-12962)Victor Stinner2019-04-261-1/+1
| | | _PyThreadState_Delete() has no return value.
* bpo-36725: regrtest: add TestResult type (GH-12960)Victor Stinner2019-04-268-208/+286
| | | | | | | | | | | | | | | * Add TestResult and MultiprocessResult types to ensure that results always have the same fields. * runtest() now handles KeyboardInterrupt * accumulate_result() and format_test_result() now takes a TestResult * cleanup_test_droppings() is now called by runtest() and mark the test as ENV_CHANGED if the test leaks support.TESTFN file. * runtest() now includes code "around" the test in the test timing * Add print_warning() in test.libregrtest.utils to standardize how libregrtest logs warnings to ease parsing the test output. * support.unload() is now called with abstest rather than test_name * Rename 'test' variable/parameter to 'test_name' * dash_R(): remove unused the_module parameter * Remove unused imports
* bpo-36710: Add runtime parameter in gcmodule.c (GH-12958)Victor Stinner2019-04-263-141/+165
| | | | Add 'state' or 'runtime' parameter to functions in gcmodule.c to avoid to rely directly on the global variable _PyRuntime.
* bpo-36710: Add runtime variable in pystate.c (GH-12956)Victor Stinner2019-04-251-142/+219
| | | | Add 'gilstate', 'runtime' or 'xidregistry' parameter to many functions on pystate.c to avoid lying on _PyRuntime global.
* bpo-36722: Debug build loads libraries built in release mode (GH-12952)Victor Stinner2019-04-255-2/+29
| | | | In debug build, import now also looks for C extensions compiled in release mode and for C extensions compiled in the stable ABI.
* bpo-35920: Windows 10 ARM32 platform support (GH-11774)Paul Monson2019-04-2517-15/+134

* bpo-21536: C extensions are no longer linked to libpython (GH-12946)Victor Stinner2019-04-257-26/+28
| | | | | | | | | | | | | | On Unix, C extensions are no longer linked to libpython. It is now possible to load a C extension built using a shared library Python with a statically linked Python. When Python is embedded, libpython must not be loaded with RTLD_LOCAL, but RTLD_GLOBAL instead. Previously, using RTLD_LOCAL, it was already not possible to load C extensions which were not linked to libpython, like C extensions of the standard library built by the "*shared*" section of Modules/Setup. distutils, python-config and python-config.py have been modified.
* bpo-35537: Document posix_spawn() change in subprocess (GH-11668)Victor Stinner2019-04-252-0/+13
| | | | | Document that subprocess.Popen no longer raise an exception on error like missing program on very specific platforms when using os.posix_spawn() is used.
* bpo-28552: Fix distutils.sysconfig for empty sys.executable (GH-12875)Victor Stinner2019-04-253-2/+11
| | | | | | | bpo-28552, bpo-7774: Fix distutils.sysconfig if sys.executable is None or an empty string: use os.getcwd() to initialize project_base. Fix also the distutils build command: don't use sys.executable if it's evaluated as false (None or empty string).
* bpo-36465: Fix test_regrtest on Windows (GH-12945)Victor Stinner2019-04-242-5/+10
| | | | | | Fix Py_DEBUG constant: check for sys.gettotalrefcount attribute rather than sys.getobjects. Update also SpecialBuilds.txt documentation.
* bpo-36465: Make release and debug ABI compatible (GH-12615)Victor Stinner2019-04-247-14/+57
| | | | | | | | | | | | | | Release build and debug build are now ABI compatible: the Py_DEBUG define no longer implies Py_TRACE_REFS define which introduces the only ABI incompatibility. A new "./configure --with-trace-refs" build option is now required to get Py_TRACE_REFS define which adds sys.getobjects() function and PYTHONDUMPREFS environment variable. Changes: * Add ./configure --with-trace-refs * Py_DEBUG no longer implies Py_TRACE_REFS
* Add @pablogsal to code owners file for Parser/pgen (GH-12944)Pablo Galindo2019-04-241-0/+3
| | | | | Add myself to the codeowners file as I would like to be automatically added as a reviewer for PRs that touch that component.
* bpo-36668: FIX reuse semaphore tracker for child processes (#5172)Thomas Moreau2019-04-243-10/+55
| | | Fix the multiprocessing.semaphore_tracker so it is reused by child processes.
* Issue 35224: Add PEP 572 (assignment expressions) to What's New (#12941)Guido van Rossum2019-04-241-0/+16
| | | This is meant as a stub, during the PyCon sprints we can iterate.
* bpo-36710: Add runtime variable to Py_InitializeEx() (GH-12939)Victor Stinner2019-04-246-71/+104
| | | | | | | | Py_InitializeEx() now uses a runtime variable passed to subfunctions, rather than working directly on the global variable _PyRuntime. Add 'runtime' parameter to _PyCoreConfig_Write(), _PySys_Create(), _PySys_InitMain(), _PyGILState_Init(), emit_stderr_warning_for_legacy_locale() and other subfunctions.
* bpo-36710: Add runtime variable to Py_FinalizeEx() (GH-12937)Victor Stinner2019-04-244-24/+29
| | | | | | * Add a 'runtime' variable to Py_FinalizeEx() rather than working directly on the global variable _PyRuntime * Add a 'runtime' parameter to _PyGC_Fini(), _PyGILState_Fini() and call_ll_exitfuncs()
* bpo-30840: Document relative imports (#12831)Joannah Nanjekye2019-04-243-1/+43
