* [3.10] bpo-44559: [Enum] revert enum module to 3.9 (GH-27010)Ethan Furman2021-07-031-28/+1
| | | * [Enum] revert enum module to 3.9
* bpo-43957: [Enum] Deprecate ``TypeError`` from containment checks. (GH-25670)Ethan Furman2021-04-271-1/+1
| | | | | In 3.12 ``True`` or ``False`` will be returned for all containment checks, with ``True`` being returned if the value is either a member of that enum or one of its members' value.

* bpo-40066: Enum: modify `repr()` and `str()` (GH-22392)Ethan Furman2021-03-301-1/+1
| | | | | | | | | * Enum: streamline repr() and str(); improve docs - repr() is now ``enum_class.member_name`` - stdlib global enums are ``module_name.member_name`` - str() is now ``member_name`` - add HOW-TO section for ``Enum`` - change main documentation to be an API reference
* bpo-43406: Fix test_signal.test_stress_modifying_handlers() (GH-24815)Victor Stinner2021-03-101-3/+13
| | | | | | | Fix a race condition of test_stress_modifying_handlers() of test_signal: only raise signals while we are in the catch_unraisable_exception() context manager. Moreover, don't check if we received at least one signal if at least one signal got ignored.
* bpo-43406: Fix possible race condition where ``PyErr_CheckSignals`` tries to ↵Antoine Pitrou2021-03-051-0/+50
| | | | | | execute a non-Python signal handler (GH-24756) We can receive signals (at the C level, in `trip_signal()` in signalmodule.c) while `signal.signal` is being called to modify the corresponding handler. Later when `PyErr_CheckSignals()` is called to handle the given signal, the handler may be a non-callable object and would raise a cryptic asynchronous exception.

* bpo-38614: Use test.support.SHORT_TIMEOUT constant (GH-17566)Victor Stinner2019-12-111-3/+3
| | | | | | | | | | | | | | | Replace hardcoded timeout constants in tests with SHORT_TIMEOUT of test.support, so it's easier to ajdust this timeout for all tests at once. SHORT_TIMEOUT is 30 seconds by default, but it can be longer depending on --timeout command line option. The change makes almost all timeouts longer, except test_reap_children() of test_support which is made 2x shorter: SHORT_TIMEOUT should be enough. If this test starts to fail, LONG_TIMEOUT should be used instead. Uniformize also "from test import support" import in some test files.
* closes bpo-38712: Add signal.pidfd_send_signal. (GH-17070)Benjamin Peterson2019-11-191-0/+19
| | | | | | | | This exposes a Linux-specific syscall for sending a signal to a process identified by a file descriptor rather than a pid. For simplicity, we don't support the siginfo_t parameter to the syscall. This parameter allows implementing a pidfd version of rt_sigqueueinfo(2), which Python also doesn't support.

* bpo-36013: delete fragile interactive shell SIGINT test (GH-11902)Gregory P. Smith2019-02-161-33/+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-35568: add 'raise_signal' function (GH-11335)Vladimir Matveev2019-01-081-12/+44
| | | | | | As in title, expose C `raise` function as `raise_function` in `signal` module. Also drop existing `raise_signal` in `_testcapi` module and replace all usages with new function. https://bugs.python.org/issue35568
* bpo-35513: Replace time.time() with time.monotonic() in tests (GH-11182)Victor Stinner2018-12-171-5/+5
| | | | | | | Replace time.time() with time.monotonic() in tests to measure time delta. test_zipfile64: display progress every minute (60 secs) rather than every 5 minutes (5*60 seconds).
* bpo-34412: Make signal.strsignal() work on HP-UX (GH-8786)Michael Osipov2018-08-231-0/+1
| | | | | | Introduce a configure check for strsignal(3) which defines HAVE_STRSIGNAL for signalmodule.c. Add some common signals on HP-UX. This change applies for Windows and HP-UX.
* bpo-34130: Fix test_signal.test_warn_on_full_buffer() (GH-8327)Victor Stinner2018-07-181-15/+41
| | | | | | | | | | | | | | | | | On Windows, sometimes test_signal.test_warn_on_full_buffer() fails to fill the socketpair buffer. In that case, the C signal handler succeed to write into the socket, it doesn't log the expected send error, and so the test fail. On Windows, the test now uses a timeout of 50 ms to fill the socketpair buffer to fix this race condition. Other changes: * Begin with large chunk size to fill the buffer to speed up the test. * Add error messages to assertion errors to more easily identify which assertion failed. * Don't set the read end of the socketpair as non-blocking.
* bpo-34130: Fix test_signal.test_socket() (GH-8326)Victor Stinner2018-07-181-1/+0
| | | | | | | | test_signal.test_socket(): On Windows, sometimes even if the C signal handler succeed to write the signal number into the write end of the socketpair, the test fails with a BlockingIOError on the non-blocking read.recv(1) because the read end of the socketpair didn't receive the byte yet. Fix the race condition on Windows by setting the read end as blocking.
* bpo-33441: Make the sigset_t converter available in other modules. (GH-6720)Serhiy Storchaka2018-05-081-0/+4
| | | | | | | | | * Expose the sigset_t converter via private API _Py_Sigset_Converter(). * Use Argument Clinic for parsing sigset_t in signalmodule.c. * Raise ValueError instead OverflowError for integers out of the C long range. Based on patch by Pablo Galindo Salgado.
