Yes but start and stop are pretty useless nowadays because almost no
terminal output is slow enough for them to be viable, it's best to
disable them. Then command line apps can work like (most) GUI ones
with a little .inputrc customization
We have three ways to quit from the utility. Should be enough.
Also can you please share the exact steps? I am pressing `^Q` at the prompt
but I don't see the segfault.
I just start the app with the command line shown in the first example,
then put Cntrl-Q at the first prompt. It's possible that it does this
for me *because* I have Cntrl-Q disabled:
$ stty -a
speed 38400 baud; rows 74; columns 80; line = 0;
intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = <undef>;
eol2 = <undef>; swtch = <undef>; start = <undef>; stop = <undef>; susp = ^Z;

Can you please share the output from from the Exception? |

It's real, so this close is premature. It's almost certainly due to
this stuff from my ~/.inputrc:
# I don't know what magic word to use for sqlite3 so we just correct for the
# other cases.
set keymap vi-insert
Control-q: ".exit\nq(save=\"no\")\n"
set keymap vi-move
Control-q: ".exit\nq(save=\"no\")\n"
# I also don't know what magic word to use for R (the one that seems to be set
# in the source doesn't work). This is what i used to use for R, plus a bit
# that was supposed to make sqlite3 work as well. But unfortunately trying to
# do both makes R seg fault on exit in an annoying way, and I don't use R at
# the moment anyway.
#Control-q: "q(save=\"no\")\n;\n.exit\n"
# The GNU readline docs use a capital B, so we do that too, by godfrey.
$if Bash
set keymap vi-insert
Control-q: "\C-d"
set keymap vi-move
Control-q: "\C-d"
$endif
$if ngspice
set keymap vi-insert
Control-q: "quit\n"
set keymap vi-move
Control-q: "quit\n"
$endif
[More similar program-specific stanzas snipped]
omnicomplete (which maybe is a python module?) shouldn't crash with a
seg fault because that first ".exit\nq(save=\"no\")\n" ends up getting
sent to it, but it does.
The annoying thing about ~/.inputrc is those program names (Bash,
ngspice, etc.) are barely documented so you have to guess or look at
source to figure out what they are, and in some cases (e.g. sqlite3) I
never managed to figure it out. So this would be a useful thing for
omnicomplete to carefully document, if it doesn't already. It's
appropriate to document at this level of detail, because command line
programs like omnicomplete and ddgr are aiming at users who stand a
good chance of caring about this sort of customizability.

My full .innputrc is included below as well. This is probably an

doubt I'm the only one who uses readline and .inputrc a lot and so
other people somewhere are likely hitting the bug, even if

I believe the answer lies in the core dump. Can you share the backtrace from it? |
|
It's bee a while since I used gdb, so I'm not sure I got the
incantation to get a backtrace right.
I did this:
1. Installed python3.4-dbg (debian package)
2. Ran ddgr using it with this command:
python3.4-dbg /home/bkerin/local/bin/ddgr hello world
3. Triggered bug as described previously
4. Launched gdb with this command:
gdb python3.4-dbg core
5. Typed 'bt' to get the backtrace as shown below:

It's the correct procedure. Also, the top 3 frames show that readline is invoked to handle the input and it fails: The 3 params passed over from the python subsystem (stdin, stdout and prompt string) have nothing unusual in them (stdin and stdout are from the env without any modifications and the prompt is a simple string). I believe this has to be looked into by the readline team for further info on what's going wrong. |

What happens if you comment out the import readline block towards the top of the ddgr file? |
|
Then the problem isn't triggerable, I guess because the stuff in
~/.inputrc doesn't apply (or I don't know how to make it apply
anyway).
I tried typing in the stuff that C-q expands to in the inputrc
(.exit\n(save=no)\n) but that doesn't reproduce the problem. Maybe I
didn't type in quite the right expansion though, I'm not sure.

That isolates the problem to the GNU readline library. I believe you can reproduce it easily without ddgr. Write a simple 3-line python3 script, import readline and call |

yep, same behavior. I've only ever seen this behavior with the python
interface (which is not to say it isn't a readline bug). If submitted
it as a bug against python3.4 with a note that it's likely a readline
bug (though I've never triggered it with any other readline-using
app).

when I do ddgr hello world, then type Cntrl-q at the prompt, ddgr dies with a seg fault
It would be sort of nice if Cntrl-q also meant quit. I have a bit of a crazed personal mission of making
Cntrl-q mean "get rid of the current thing" across all my software. Of course it sort of works as it is so maybe I shouldn't be reporting this issue :)
