* Add _PyCoreConfig_ReadFromArgv() function which parses command line
options: move code from main.c to coreconfig.c.
* Add _PyCoreConfig_Write() to write the new configuration: coerce
the LC_CTYPE locale, set Py_xxx global configuration variables,
etc.
* _PyCoreConfig_ReadFromArgv() now only changes the LC_CTYPE locale
temporarily. _PyCoreConfig_Write() becomes responsible to set the
LC_CTYPE locale.
* Add _Py_SetArgcArgv() and _Py_ClearArgcArgv() functions
* Rename many "pymain_xxx()" functions
* Add "const" to some function parameters
* Reorganize main.c to declare functions in the order in which they
are called.
* Move fields from _PyMain to _PyCoreConfig:
* skip_first_line
* run_command
* run_module
* run_filename
* Replace _PyMain.stdin_is_interactive with a new
stdin_is_interactive(config) function
* Rename _PyMain to _PyArgv. Add "const _PyArgv *args" field
to _PyCmdline.
Add a new _Py_INIT_EXIT() macro to be able to exit Python with an
exitcode using _PyInitError API. Rewrite function calls by
pymain_main() to use _PyInitError.
Changes:
* Remove _PyMain.err and _PyMain.status field
* Add _Py_INIT_EXIT() macro and _PyInitError.exitcode field.
* Rename _Py_FatalInitError() to _Py_ExitInitError().
The whole coreconfig.h header is now excluded from Py_LIMITED_API.
Move functions definitions into a new internal pycore_coreconfig.h
header.
* Move Include/coreconfig.h to Include/cpython/coreconfig.h
* coreconfig.h header is now excluded from Py_LIMITED_API
* Move functions to pycore_coreconfig.h
Ensure that the main interpreter is active (in the main thread) for signal-handling operations. This is increasingly relevant as people use subinterpreters more.
https://bugs.python.org/issue35724
Trying to assign a value to __debug__ using the assignment operator is supposed to fail, but
a missing check for forbidden names when setting the context in the ast was preventing this behaviour.
Explicitly reinitialize this every eval *just in case* someone is
calling into an embedded Python where they don't care about an uncaught
KeyboardInterrupt exception (why didn't they leave
`config.install_signal_handlers` set to `0`?!?) but then later call
`Py_Main()` itself (which *checks* this flag and dies with a signal after
its interpreter exits). We don't want a previous embedded interpreter's
uncaught exception to trigger an unexplained signal exit from a future
`Py_Main()` based one.
* 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.
