The "python" command (and the Python implementation of the gdb "source" command) does not handle Python exceptions in the same way as other gdb-facing Python code. In particular, exceptions are turned into a generic error rather than being routed through gdbpy_handle_exception, which takes care of converting to 'quit' as appropriate. I think this was done this way because PyRun_SimpleFile and friends do not propagate the Python exception -- they simply indicate that one occurred. This patch reimplements these functions to respect the general gdb convention here. As a bonus, some Windows-specific code can be removed, as can the _execute_file function. The bulk of this change is tweaking the test suite to match the new way that exceptions are displayed. These changes are largely uninteresting. However, it's worth pointing out the py-error.exp change. Here, the failure changes because the test changes the host charset to something that isn't supported by Python. This then results in a weird error in the new setup. Bug: https://sourceware.org/bugzilla/show_bug.cgi?id=31354 Acked-By: Tom de Vries <tdevries@suse.de> Reviewed-By: Eli Zaretskii <eliz@gnu.org>
