This + is needed for pipes that terminate abnormally or return failed + termination. Pipe and stdio streams have an extra description field + so they are printed in a readable way. + + * lib.c (process_error): New global defined. + (obj_init): New symbol interned. + (lazy_stream_func): Pass t to close_stream, so exception + is thrown if the close fails. + (lazy_stream_cons): Ditto. + + * lib.h (process_error): Declared. + + * match.c (complex_snarf): Pass new desr argument to make_stdio_stream + and make_pipe_stream. + + * stream.c (strm_ops): New argument on close function pointer. + (common_destroy): Close without throwing exception. For objects + being finalized, we don't care if the close works or not; the + program has shown that it doesn't care about the stream by + letting it become unreachable, so we don't bother the program + by throwing an exception. + (stdio_handle): New struct. + (stdio_stream_print, stdio_stream_destroy, stdio_stream_mark, + stdio_maybe_read_error, stdio_maybe_write_error): New functions. + (stdio_put_string, stdio_put_char, stdio_get_line, + stdio_get_char, stdio_vcformat, stdio_close): Updated to new + handle format, and throw errors now. + (stdio_ops, pipe_ops): Redirected to new functions stdio_stream_print, + stdio_stream_destroy and stdio_stream_mark. + (pipe_close): Updated to new handle format. Parses status from + pclose and throws exceptions appropriate to the situation. + (dir_close): Takes extra argument. + (make_stdio_stream, make_pipe_stream): New argument added. + (make_string_output_stream): Some casts added. + (close_stream): Pass new argument down to virtual function. + (stream_init): Pass new argument to make_stdio_stream + when creating streams for stdin, stdout and stderr. + + * stream.h (make_stdio_stream, make_pipe_stream, close_stream): + Declarations updated. + + * txr.c (txr_main): Pass new argument to make_stdio_stream. + + * unwind.c (uw_init): Register process_error. + 2009-11-01 Kaz Kylheku <kkylheku@gmail.com> Version 020 |
