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.
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.
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.
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`
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__.
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.
add:
* `_simple_enum` decorator to transform a normal class into an enum
* `_test_simple_enum` function to compare
* `_old_convert_` to enable checking `_convert_` generated enums
`_simple_enum` takes a normal class and converts it into an enum:
@simple_enum(Enum)
class Color:
RED = 1
GREEN = 2
BLUE = 3
`_old_convert_` works much like` _convert_` does, using the original logic:
# in a test file
import socket, enum
CheckedAddressFamily = enum._old_convert_(
enum.IntEnum, 'AddressFamily', 'socket',
lambda C: C.isupper() and C.startswith('AF_'),
source=_socket,
)
`_test_simple_enum` takes a traditional enum and a simple enum and
compares the two:
# in the REPL or the same module as Color
class CheckedColor(Enum):
RED = 1
GREEN = 2
BLUE = 3
_test_simple_enum(CheckedColor, Color)
_test_simple_enum(CheckedAddressFamily, socket.AddressFamily)
Any important differences will raise a TypeError

* 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
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.
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.
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.
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.
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 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.
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.

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).
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.
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.
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.
* 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.
