I added gitdm stats awhile back although the mappings could certainly do with some clean-up. For the last year of activity the stats are:

Sorry, what project is this? GCC?

[–] [email protected] 1 points 10 months ago (1 children)

Sorry yes this was GCC, I can do the same for the rust repo if you want.

[–] BatmanAoD 1 points 10 months ago (1 children)

That would be helpful! Thank you.

It looks like a lot of mappings need adding as most people come up as unknown:

EDIT updated with newer mappings.

I didn't know about gitdm; that's a handy tool! Looks like those are just based on the domain of the email addresses used for commits, so it doesn't necessarily indicate whether the company employees people specifically to work on GCC. But I think you're right, that does indicate quite a lot of corporate support for the project.

[–] [email protected] 1 points 10 months ago

The gitdm scripts come from LWN who do a regular "who writes the kernel" report but can work on any git repo.

You can be fairly certain that patches coming from a corporate domain are paid for their time. You can add extra metadata to track people who use personal or org addresses if they confirm it's a paid gig. The project I work on most is about 75% paid contributors with hobbyists and academics making up the rest. The good unpaid contributors can often get hired if they want to be.
