How to add a distro feature from an image recipe?

How to add a distro feature from an image recipe?

Hi,

Is there a specific mechanism to add a distro feature from an image recipe?
DISTRO_FEATURES_append does not seem to work from an image-*.bb or from a packagegroup-*.bb.

Or, if not, what would be the best way to achieve this?
The need is that I have a number of images and only want to add a certain distro feature (ptest) to just one or two of them (some test images).

Thanks,

Gabriel

Couldn't that be achieved by just adding "ptest-pkgs" to IMAGE_FEATURES in the
image recipe? or "ptest-pkgs" to EXTRA_IMAGE_FEATURES in your local.conf?

No, unfortunately not; ptest-pkgs are not sufficient for control of this 
feature. If you have ptest in DISTRO_FEATURES, the ptests are still 
being built for your image.

It would be possible to disable the feature from local.conf though, but 
I would have liked to avoid particularizing this file per image.

Thanks,

Gabriel

You can't do this I'm afraid. DISTRO_FEATURES influences how components are 
built, and aside from via dependencies and placing files in the sysroot, one 
recipe cannot influence how another is built. If you think about how the system 
produces package feeds and how these would be expected to be able to be 
installed from a running target system, if it were possible to set these kinds 
of options from the image you would have situations where you would build one 
image and then build another and packages would change, possibly in ways that 
would not be compatible with the first image - so that wouldn't be practical.

You can have ptest enabled in the distro but ptest packages installed only in 
certain images. That is the only way this kind of thing can work. If enabling 
the ptest in DISTRO_FEATURES is causing changes in an image where ptest is not 
installed, that should be considered a bug.

Hi Paul,

Yes, I was afraid it’s this way :)
Alright, I can settle for just not having them installed.

But what I’m witnessing now is that having:
"ptest" in my DISTRO_FEATURES, and
no "ptest-pkgs" in IMAGE_FEATURES
results in the image having ptests installed.

And thanks to your explanation, I understand better I’m likely looking 
at a bug.
I will investigate closer.

Thanks,

Gabriel

Is that bug 5702, or something else?

Possibly more. Right now I only see:
./dbus-ptest/ptest
./perl/ptest

in a custom image I have, but I will also try with a bigger image to 
check if I get more.

So the dbus-ptest one we're aware of (and the fix is on the mailing list) but 
it would be interesting to know how the perl-ptest one got there.

Right, I will investigate.
