[3.15] gh-152132: Fix Py_RunMain() to return an exit code (GH-153446)#153454
Merged
Conversation
…3446) * 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 fac72f1) Co-authored-by: Victor Stinner <vstinner@python.org>

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:
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.
