Re: [Linaro-uefi] [RFC] Use commit id as default FIRMWARE_VER

I have got the similar lines in my CI system. It is quite useful.

I like the feature from the Linux script where it will use an (annotated) tag if one exists. I thought that would be useful for releases. But that's relies on the tags being annotated, which we rarely do.

When the engineer build the firmware on his/her machine I leave the version empty.

With our new Platforms releases, the users are all building from source now, so that's my main use case - to make sure they're building from the correct source ;-)

I'm also thinking about a similar patch for ARM-TF.

But your ‘-dirty’ addition is also useful.

Yes, it should help me identify sneaky users!!

Hello UEFI builders!

I'd like your feedback on this patch.

I often look at boot logs from LAVA and other people and don't quite know where the UEFI binary came from. With ones that I've provided, I can often recognise the build date stamp. But at other times, I'm simply trying to work out if someone is building the code they say they are, or some other code.

As the commit message says, rather than leaving the version string blank, my patch will append the git commit id of the current commit, with "dirty" appended if the user is building with uncommited mods.

I considered including the code from linux scripts/setlocalversion, but apart from giving me a "-" at the front, I thought it was overkill.

Comments?

Cheers,

Ryan.

If a FIRMWARE_VER setting is not provided and we are building from a GIT repo, provide a default value based on the SHA ID of the commit where we built from.

If the repo has local uncommited changes, then we mark the version string with "-dirty".

This is based loosely on the same idea from the linux kernel in: scripts/setlocalversion
