* bpo-35992: Use PySequence_GetItem only if sq_item is not NULL (GH-11857)Ivan Levkivskyi2019-02-171-1/+8
| | | | Not using `__class_getitem__()` fallback if there is a non-subcriptable metaclass was caused by a certain asymmetry between how `PySequenceMethods` and `PyMappingMethods` are used in `PyObject_GetItem`. This PR removes this asymmetry. No tests failed, so I assume it was not intentional.
* bpo-36013: delete fragile interactive shell SIGINT test (GH-11902)Gregory P. Smith2019-02-171-33/+7
| | | | | It makes the existing smaller test more readable and robust at the same time. The execution of a shell in interactive mode from CI and buildbot test automation wasn't working out. What would work locally in our terminals would only work within a fraction of automation systems. The integration test was a nice to have. painful. deleting. :)

* bpo-1054041: Exit properly after an uncaught ^C. (#11862)Gregory P. Smith2019-02-161-4/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * bpo-1054041: Exit properly by a signal after a ^C. An uncaught KeyboardInterrupt exception means the user pressed ^C and our code did not handle it. Programs that install SIGINT handlers are supposed to reraise the SIGINT signal to the SIG_DFL handler in order to exit in a manner that their calling process can detect that they died due to a Ctrl-C. https://www.cons.org/cracauer/sigint.html After this change on POSIX systems while true; do python -c 'import time; time.sleep(23)'; done can be stopped via a simple Ctrl-C instead of the shell infinitely restarting a new python process. What to do on Windows, or if anything needs to be done there has not yet been determined. That belongs in its own PR. TODO(gpshead): A unittest for this behavior is still needed. * Do the unhandled ^C check after pymain_free. * Return STATUS_CONTROL_C_EXIT on Windows. * Fix ifdef around unistd.h include. * 📜🤖 Added by blurb_it. * Add STATUS_CTRL_C_EXIT to the os module on Windows * Add unittests. * Don't send CTRL_C_EVENT in the Windows test. It was causing CI systems to bail out of the entire test suite. See https://dev.azure.com/Python/cpython/_build/results?buildId=37980 for example. * Correct posix test (fail on macOS?) check. * STATUS_CONTROL_C_EXIT must be unsigned. * Improve the error message. * test typo :) * Skip if the bash version is too old. ...and rename the windows test to reflect what it does. * min bash version is 4.4, detect no bash. * restore a blank line i didn't mean to delete. * PyErr_Occurred() before the Py_DECREF(co); * Don't add os.STATUS_CONTROL_C_EXIT as a constant. * Update the Windows test comment. * Refactor common logic into a run_eval_code_obj fn.

* bpo-35931: Gracefully handle SyntaxError in pdb debug command (GH-11782)Daniel Hahler2019-02-152-1/+15
| | | | | | | | Previously, `debug print(` would cause the interpreter to exit on a SyntaxError whereas `print(` would properly display the error and return to the pdb prompt. This patch fixes this by pre-compiling the code before passing it to `Pdb.run`. https://bugs.python.org/issue35931

Not only a blocking IO error needs to be ignored - permission errors also need to be ignored. p.s. - iirc as a "test" only correction a NEWS item is not required. If this is not correct - just mention, and I'll add a NEWS blurb. https://bugs.python.org/issue35633

* bpo-35378: Fix multiprocessing.Pool references (GH-11627)Pablo Galindo2019-02-112-39/+74
| | | | | | | | | Changes in this commit: 1. Use a _strong_ reference between the Pool and associated iterators 2. Rework PR #8450 to eliminate a cycle in the Pool. There is no test in this commit because any test that automatically tests this behaviour needs to eliminate the pool before joining the pool to check that the pool object is garbaged collected/does not hang. But doing this will potentially leak threads and processes (see https://bugs.python.org/issue35413).

| | | | | (GH-11801) Keeping references to processes and managers between tests makes them count as dangling processes.

| | | | | | | | | | | | | | | | | | | | | | | | | | * Make timedelta return subclass types Previously timedelta would always return the `date` and `datetime` types, regardless of what it is added to. This makes it return an object of the type it was added to. * Add tests for timedelta arithmetic on subclasses * Make pure python timedelta return subclass types * Add test for fromtimestamp with tz argument * Add tests for subclass behavior in now * Add news entry.
