[3.14] gh-152132: Fix Py_RunMain() to return an exit code (#153446) (#153455)
gh-152132: Fix Py_RunMain() to return an exit code (#153446)
* Fix Py_RunMain() to return an exit code, rather than calling
Py_Exit(), when running a script, a command, or the REPL.
* _PyRun_SimpleFile() now logs errors to stderr, for example if setting
__main__.__file__ fails.
* Add tests on Py_RunMain() exitcode.
* Rename functions:
* _PyRun_SimpleStringFlagsWithName() => _PyRun_SimpleString()
* _PyRun_SimpleFileObject() => _PyRun_SimpleFile()
* _PyRun_AnyFileObject() => _PyRun_AnyFile()
* _PyRun_InteractiveLoopObject() => _PyRun_InteractiveLoop()
* Change _PyRun_SimpleString(), _PyRun_SimpleFile(), _PyRun_AnyFile() and
_PyRun_InteractiveLoop() return type to PyObject*.
* pymain_repl() now displays the error if PySys_Audit() or
import _pyrepl failed.
* PyRun_SimpleFileExFlags() and PyRun_AnyFileExFlags() now log
PyUnicode_DecodeFSDefault() error. So these functions can no longer
return -1 with an exception set.
(cherry picked from commit fac72f1ee9)
(cherry picked from commit 62c34a62c2)
Remove these private functions from the public C API:
* _PyRun_AnyFileObject()
* _PyRun_InteractiveLoopObject()
* _PyRun_SimpleFileObject()
* _Py_SourceAsString()
Move them to the internal C API: add a new pycore_pythonrun.h header
file. No longer export these functions.
