[Qt-creator] More issues with QtCreator using dockers

[Marcus Tillmanns]

Hi Jochen,


1. You can select different docker devices for build and run. But the debugger is always taken from the build docker. One cannot even select
a debugger from the run device manually. This is a blocker as the build device cannot run the application (that's the reason why you have a
separate run device and docker image).

We currently (and historically) assume that:
* For docker: You can run and build on the same device
* For ssh run device: You cannot debug directly on the run device, but need the debugger to come from the build device

There is no provision for “dual docker device” setups at the moment.


2. The default name of the kit is %{Device:Name}. The Device:Name is taken from the Run device which surprises me because the build device
is surely more important, isn't it?

This is historical, since in the beginning there was only the Run device, while building would happen locally. It might make sense to put both information into the default name these days.


3. Qt Version, Compilers and Debuggers are all named after the docker image name, tag, id and some extra text. At least in my case the
docker image names are build from the docker registry (some artifactory name), some folders to structure the dockers and the tag (which is
pretty long as it lists several component versions used in the image). At the end the strings are something like 160 characters long which
is an issue in the UI.

Maybe open a ticket with some screenshots of the particular issues.

4. Detected debuggers are never removed automatically and cannot be removed manually. While Qt versions and compilers are removed
automatically when the device is deleted, the detected debuggers stay and the list grows longer and longer over time.

This should be fixed in Qt Creator 18.0.

All in all there are far too many steps needed to get a clean device and kit set up to build and run and application using docker. The new
concept with the json description in QtC 18 seems like a good way to go. Does this solve some of the issues (like the naming or selection of
the debugger)?

No, this does not change the way debuggers are chosen.

Please feel free to open Tickets for the issues plaguing you. You could also try the Qt Creator 18 rc1 snapshots (https://download.qt.io/snapshots/qtcreator/18.0/18.0.0-rc1/)

Cheers,
Marcus
