--gen-swversions with "installed-directly = true"

[Chris]

I have a sw-description with 2 images that are both "installed-directly = true".  When I try to use --gen-swversions with this .swu, I notice that the swversions file is created at the end of a successful install, but it is empty.  I've check the $? return from swupdate and it's 0 (no errors) and it's definitely not a filesystem/sync/permission issue.  Any help in this matter would be helpful.

Hi Chris,

I think this is linked to the current implementation of the --gen-swversions option.
This issue has already been discovered here [0] and is linked to the fact the versions are not updated when the artifact is marked to be streamed.
A patch fixing this issue has been posted in the mentioned thread.

Have a great day,

Hi Clement,

Sorry, I should have mentioned I tried this patch (I'm running 2024.12.1) and it didn't work (I still get an empty file).  So I thought maybe that patch was not useful since it never got accepted.  Has anyone else tested this patch?

Thanks,

Chris

Hey Chris,

I don't know why the patch wasn't accepted -- I had just assumed that Stefano missed it.  I'll check what version of swupdate I am using, but I can tell you that the patch does work for me. I use it almost daily.

There is not patch...

Patch is not in patchwork, it was not submitted to this ML for review,
and it is must be formally correct (with Signed-off-by, etc.). I go
through patchwork to check if there is something left and open, and if
it is not there, it won't be applied.

Best regards,
Stefano

Right, I mentioned that I could formally submit it if you felt that it was a good thing to submit.  I can try to do it formally when I have time.

Hey Chris,

I am using v2024.05.2 on this particular device.

Hi Mark,

(Hopefully not double posting, I thought I sent this but maybe didn't go through).

I took some time to look at the code (including the patch) and I realized I was misunderstanding what to expect from the --gen-swversions command.  I was expecting the top level "version" attribute in the swdescription to show up in this file.  However, the feature only lists the versions (if specified) for images files.  Since I didn't have any "version" attributes in my two images sections, I was ending up with an empty swversion file.

For anyone in the future reading this that was confused like I was, you need to make sure the sw-description has a "name" and "version" attribute defined in each of the images files you want to see in swversions file.

I'm not sure if having the top-level version makes sense in the swversions as part of this feature.  I will leave that up to the developers to ponder this.

Thanks,
Chris
