In the TUI mode, we call wrefresh after outputting every single character. This results in the I/O becoming very slow. Fix this by delaying refreshing the console window until an explicit flush of gdb_stdout is requested, or a write to any other (unbuffered) file is done. 2015-02-04 Doug Evans <dje@google.com> Pedro Alves <palves@redhat.com> Eli Zaretskii <eliz@gnu.org> PR tui/17810 * tui/tui-command.c (tui_refresh_cmd_win): New function. * tui/tui-command.c (tui_refresh_cmd_win): Declare. * tui/tui-file.c: #include tui/tui-command.h. (tui_file_fputs): Refresh command window if stream is not gdb_stdout. (tui_file_flush): Refresh command window if stream is gdb_stdout. * tui/tui-io.c (tui_puts): Remove calls to wrefresh, fflush.
