ci: add job to check increase in binary size

[snprajwal]

This job checks the difference in binary size across commits in a PR, and fails if the difference is more than a set maximum limit. This allows us to detect early on if there is any possible bloating in the binary due to poorly structured dependencies. The job can be overridden by adding a bloat-ok label to the PR.

fatal: invalid upstream 'main^'

Slightly weird. This works locally, even with the single quotes. I'll debug it on a separate branch.

[snprajwal]

Right, now the workflow can't find the test/check-size.sh file.

[adrianreber]

Looks good. Can you make CI happy using the bloat-ok label?

[snprajwal]

I don't seem to have the rights to add labels to the PR

[adrianreber]

I added the label. It still runs the job. I thought it should ignore it now.

[snprajwal]

I thought the same too 🤔 weird behaviour

[snprajwal]

Nice, the workflow doesn't run since the PR is labeled. Can either of you please remove the label so we can see if it gets triggered. Also, I've added a line to test if the script is found by the CI shell. If that works, I'll remove and force push so that we can merge this

[snprajwal]

Great! The script is present, getting rid of the test and pushing.

[snprajwal]

:thinking: why did it not run now

[snprajwal]

Ah, got it. I overrode the default triggers for PR events.

[snprajwal]

Now we're good to go! :tada:

[snprajwal]

@rst0git can you add the label to make CI happy please?
