Bug ID: 29582
Summary: Usability improvement: CTRL+C when debugindod client
is downloading a file
Product: gdb
Version: HEAD
Status: NEW
Severity: normal
Priority: P2
Component: cli
Assignee: unassigned at sourceware dot org
Reporter: mliska at suse dot cz
CC: fchen0000 at gmail dot com, vries at gcc dot gnu.org
Target Milestone: ---
Let's imagine you're debugging a binary with many shared libs and you're in the
middle of downloading debuginfo of the shared libs, you press CTRL+C.
At that point, the running downloading is terminated and gdb continues
downloading the next debug info. I would expect to be asked if I want to
terminate all future downloading or not. Having that one can easily exit a
debugging session instead of waiting for the cancelation of all the downloading
stuff.
Example:

As long as debuginfod remains enabled gdb will query the user every time they
cancel a download. I think it would be preferable for gdb to remember when the
user answered "n" so that individual downloads can be cancelled without having
to answer the query each time.
Maybe we should also add a gdb command such as 'set debuginfod cancel-all
on/off' so that the behavior of ctrl-c during downloads can be set without
having to answer the query every session. 'on' could mean ctrl-c disables
debuginfod while 'off' only cancels the current download.

Good points.
I've come up with "set debuginfod cancel one/all/ask" to address these.

Thanks for the patch, I think this works nicely. I just have a couple
suggestions regarding some of the wording.

Here it could be useful to include instructions for how to re-enable
debuginfod. Something like:
"Debuginfod has been disabled. To re-enable use the 'set debuginfod enabled on'
command."
> + add_setshow_enum_cmd ("cancel", class_run, debuginfod_cancel_enum,

> + _("Show cancellation mode for debuginfod."),
> + _("\
> +When set to one, ^C cancels a single download.\n\
> +When set to all, ^C cancels all further downloads.\n\
> +When set to ask, ^C asks what to do."),
To be extra clear about what the cancellation mode is I'd add the following
line:
The cancellation mode controls the behavior of ^C while a file is downloading
from debuginfod.\n\
When set to one, ^C cancels a single download.\n\
