* gh-124083: Skip test_signal.test_strsignal() on NetBSD (#124084)Furkan Onder2024-09-181-0/+2
| | | Skip test_strsignal() on NetBSD due to TypeError.
* gh-116622: Switch test_stress_delivery_simultaneous from SIGUSR1 to SIGUSR2 ↵Malcolm Smith2024-09-121-3/+6
| | | | | (#123981) Use SIGUSR1 instead of SIGUSR2 to improve reliability of signal stress test on Android.
* gh-121065: Temporarily skip flaky test on free-threaded build (#121100)Sam Gross2024-06-271-0/+1
|
* gh-120039: Reduce expected timeout in test_siginterrupt_off (#120047)Sam Gross2024-06-041-3/+3
| | | | | The process is expected to time out. In the refleak builds, `support.SHORT_TIMEOUT` is often five minutes and we run the tests six times, so test_signal was taking >30 minutes.
* gh-114099: Add test exclusions to support running the test suite on iOS ↵Russell Keith-Magee2024-02-051-4/+5
| | | | | | | | | | | | | (#114889) Add test annotations required to run the test suite on iOS (PEP 730). The majority of the change involve annotating tests that use subprocess, but are skipped on Emscripten/WASI for other reasons, and including iOS/tvOS/watchOS under the same umbrella as macOS/darwin checks. `is_apple` and `is_apple_mobile` test helpers have been added to identify *any* Apple platform, and "any Apple platform except macOS", respectively.
* gh-112559: Avoid unnecessary conversion attempts to enum_klass in signal.py ↵Yilei Yang2023-12-241-0/+26
| | | | (#113040)
* gh-110017: Disable test_signal.test_stress_modifying_handlers on macOS (#112834)Ronald Oussoren2023-12-071-0/+1
| | | | | Test test_stress_modifying_handlers in test_signal can crash the interpreter due to a bug in macOS. Filed as FB13453490 with Apple.
* gh-110647: Fix signal test_stress_modifying_handlers() (#110650)Victor Stinner2023-10-101-2/+2
| | | | * cycle_handlers() now waits until at least one signal is received. * num_received_signals can be equal to num_sent_signals.
* gh-108416: Mark slow but not CPU bound test methods with ↵Serhiy Storchaka2023-09-051-0/+1

* GH-102397: Fix segfault from race condition in signal handling (#102399)Kumar Aditya2023-03-081-0/+15
| | | Co-authored-by: Gregory P. Smith <greg@krypto.org>
* Call busy_retry() and sleeping_retry() with error=True (#93871)Victor Stinner2022-06-161-11/+3
| | | | Tests no longer call busy_retry() and sleeping_retry() with error=False: raise an exception if the loop times out.
* Tests call sleeping_retry() with SHORT_TIMEOUT (#93870)Victor Stinner2022-06-151-2/+2
| | | | | | | Tests now call busy_retry() and sleeping_retry() with SHORT_TIMEOUT or LONG_TIMEOUT (of test.support), rather than hardcoded constants. Add also WAIT_ACTIVE_CHILDREN_TIMEOUT constant to _test_multiprocessing.
* Add test.support.busy_retry() (#93770)Victor Stinner2022-06-151-12/+13
| | | Add busy_retry() and sleeping_retry() functions to test.support.
* gh-90473: Decrease recursion limit and skip tests on WASI (GH-92803)Christian Heimes2022-05-191-0/+6
|
* gh-90473: WASI: Mark tests that require os.pipe() (GH-92837)Christian Heimes2022-05-161-0/+4

* gh-64783: Don't check value of SIG_DFL and SIG_IGN (#92350)Christian Heimes2022-05-051-0/+3
|
* gh-64783: Fix signal.NSIG value on FreeBSD (#91929)Victor Stinner2022-04-251-0/+10
| | | | | | | | | Fix signal.NSIG value on FreeBSD to accept signal numbers greater than 32, like signal.SIGRTMIN and signal.SIGRTMAX. * Add Py_NSIG constant. * Add pycore_signal.h internal header file. * _Py_Sigset_Converter() now includes the range of valid signals in the error message.
* bpo-40280: Detect missing threading on WASM platforms (GH-32352)Christian Heimes2022-04-071-0/+6

* Revert "bpo-40066: [Enum] update str() and format() output (GH-30582)" ↵Victor Stinner2022-01-171-1/+1
| | | | | (GH-30632) This reverts commit acf7403f9baea3ae1119fc6b4a3298522188bf96.
* bpo-40066: [Enum] update str() and format() output (GH-30582)Ethan Furman2022-01-161-1/+1
| | | | | | | | | | | | | | | Undo rejected PEP-663 changes: - restore `repr()` to its 3.10 status - restore `str()` to its 3.10 status New changes: - `IntEnum` and `IntFlag` now leave `__str__` as the original `int.__str__` so that str() and format() return the same result - zero-valued flags without a name have a slightly changed repr(), e.g. `repr(Color(0)) == '<Color: 0>'` - update `dir()` for mixed-in types to return all the methods and attributes of the mixed-in type - added `_numeric_repr_` to `Flag` to control display of unnamed values - enums without doc strings have a more comprehensive doc string added - `ReprEnum` added -- inheriting from this makes it so only `__repr__` is replaced, not `__str__` nor `__format__`; `IntEnum`, `IntFlag`, and `StrEnum` all inherit from `ReprEnum`
* bpo-27718: Fix help for the signal module (GH-30063)Serhiy Storchaka2021-12-131-0/+9
| | | | | | | Functions signal(), getsignal(), pthread_sigmask(), sigpending(), sigwait() and valid_signals() were omitted. If __all__ is not defined all non-builtin functions should have correct __module__.
* 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-38659: [Enum] add _simple_enum decorator (GH-25497)Ethan Furman2021-04-211-0/+27

* bpo-40066: Enum: modify `repr()` and `str()` (GH-22392)Ethan Furman2021-03-311-1/+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-42413: socket.timeout is now an alias of TimeoutError (GH-23413)Christian Heimes2020-11-201-1/+1

* bpo-39157: Skip test_pidfd_send_signal if the system does not have enough ↵Pablo Galindo2019-12-291-0/+2
| | | | privileges to use pidfd (GH-17740)
* 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 Peterson2019-11-201-0/+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.
* Remove unused imports in tests (GH-14518)Victor Stinner2019-07-011-1/+0

* 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-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.
* bpo-33332: Add signal.valid_signals() (GH-6581)Antoine Pitrou2018-05-041-0/+30
