Re: [Crash-utility] "gdb" by itself ought to put crash into a "gdb" mode

Well, ok, I kept stumble fingering the gdb commands, so here's a working patch.
Under the covers, the "cmd_gdb" peeks into the command when it sees it is a
"set" command. It already does this. But if it is a "set gdb"
command, then
it just redirects to the internal "cmd_set" function. I also jiggered the
arguments to accommodate the fact that the first argument is no longer "gdb".
And I fixed the prompt to be "gdb> " to distinguish from both
"crash> " and
"(gdb) ". I also really hate procedures that go beyond 100 lines or so,
so I did not add to the cmd_set length.
Hi Bruce,
I just ran a quick test of your patch, and one thing I noted
immediately is when running "set variable" with no argument,
which should just show the current setting:
crash> help set
...
This command may also be used to set internal crash variables. If no value
argument is entered, the current value of the crash variable is shown. These
are the crash variables, acceptable arguments, and purpose:
...
But with your patch,
crash> set scroll
scroll: on (/usr/bin/less)
crash> set debug
debug: 0
crash> set silent
silent: off
crash> set gdb
Segmentation fault
$
I'm not exactly sure why it works OK for the other variables,
but not for "gdb". Anyway, I'll get back to it on Monday...
Thanks,
Dave
