revamp error handling
In "error" and similar functions that ultimately call it, simply throw
an exception that contains information about the error (message, id,
stack info) instead of printing an error message immediately and then
throwing an exception. The new approach is more flexible and sllows
for some simplification of the error message routines as they no
longer need feedback from the interpreter to know when to display or
buffer messages. It is now the responsibility of any code that
catches an execution exception to determine whether and when to
display error messages.
* quit.h, quit.cc (class frame_info): New class.
(execution_exception::m_err_type, execution_exception::m_id,
execution_exception::m_message, execution_exception::m_stack_info):
New data members.
(class execution_exception): Store error type, message, id, and stack
info. Provide methods setting and accessing data as needed and for
generating stack trace message from stack info.
(execution_exception::m_stack_trace): Delete data member.
execution_exception::set_stack_trace): Delete method.
(execution_exception::set_err_type, execution_exception::err_type,
execution_exception::stack_trace, execution_exception::set_identifier,
execution_exception::identifier, execution_exception::message,
execution_exception::set_stack_info, execution_exception::display):
New methods.
* call-stack.cc, call-stack.h (call_stack::backtrace_info):
New functions.
* oct-parse.yy (maybe_print_last_error_message): Delete function and
all uses.
* pt-eval.h, pt-eval.cc (tree_evaluator::backtrace_info,
tree_evaluator::backtrace_message): New functions.
(tree_evaluator::backtrace): Now const.
(tree_evaluator::visit_unwind_protect_command,
tree_evaluator::do_unwind_protect_cleanup_code,
tree_evaluator::visit_try_catch_command, tree_evaluator::evalin,
tree_evaluator::eval, tree_evaluator::repl, debugger::repl): Save
current exception info.
* interpreter.h, interpreter.cc (interpreter::handle_exception):
New function. Use it in place of direct calls to
error_system::save_exception, error_system::display_exception (or
execution_exception::display) and interpreter::recover_from_exception,
so that we have uniform behavior when responding to an execution
exception.
* error.h, error.cc (error_system::m_buffer_error_messages,
error_system::m_discard_error_messages, error_system::m_in_try_catch):
Delete data members and associated functions. Remove all uses.
Because the error system no longer displays messages immediately,
it does not need to track whether to discard or buffer error messages
or know whether error and warning functions are invoked inside of
try-catch blocks. Everywhere that catches execution_exceptions must
now handle saving the exception state (for lasterror) and displaying
the error message and traceback as needed.
(): Delete functions and all uses.
(error_stack_frame): Delete struct definition.
(verror, vpr_where, pr_where_internal, pr_where, maybe_enter_debugger,
make_execution_exception, vmessage_with_id, message_with_id,
error_system::maybe_enter_debugger, reset_error_handler,
error_system::reset): Delete functions and all uses.
(error_system::try_option): Delete enum and all uses.
(vusage, error_1, error_system::vwarning,
error_system::rethrow_error, error_system::interpreter_try):
Simplify.
(format_message, make_stack_map, error_system::throw_error,
error_system::save_exception, error_system::display_exception):
New functions.
(Ferror): Update for error_system changes.
