             Bug #: 14584
           Summary: Scrolling does not work in TUI mode
           Product: gdb
           Version: 7.4
            Status: NEW
          Severity: normal
          Priority: P2
         Component: tui
        AssignedTo: unassigned@sourceware.org
        ReportedBy: byron@hawkinssoftware.net
    Classification: Unclassified


It is not possible to scroll up in the CMD window in TUI mode. Only the SRC
window will scroll. Setting focus to the CMD window does not change the
problem. All of the following keys are ignored: {PgUp,PgDn,<,>,+,-}, and the up
and down arrows traverse the command history. This makes TUI mode substantially
useless, because it is not possible to see the output of past values. One can
enable logging and tail the log, but the log fails to report the commands from
which the output was generated (and therefore the log is overall quite
useless). 

The debugger is only usable when all past session information can be seen by
scrolling back to it (and he logging output is only usable when it contains
both the commands and the resulting output).

GDB 7.4-2012.04 
Ubuntu 12.04
  kernel version 3.2.0-29-generic
x86 PC

Thanks for your help with this.

set trace-commands on


Otherwise you are right that readline library does not provide any real
terminal, it cares only about the current line.  GDB uses 'set pagination on'
so that no output is accidentally lost but what is scrolled away is really
lost. Maybe you would prefer some other front end besides TUI:

Actually with "set trace-commands on" I can just tail the log. (I searched for
a long time trying to find such a setting and did not come up with anything.)
The graphical interfaces seem to always be missing essential things, like
printing assembly at an arbitrary address, so I will use TUI with logging.

It still seems unfortunate that TUI mode is so convenient, yet destroys the
output. If it would just work the same as GDB without TUI mode, it would be
great.
