[PATCH 1/2] poky.conf: allow changes to DISTRO_VERSION, SDK_VERSION and MAINTAINER

[Mikko Rapeli]

For users who build their own variants of poky, they want to stay close
to poky.conf and thus use it, but would still like to change the
version details and maintainers to their own. With this change
these variables can be changed in local.conf, for example.

[PATCH 2/2] git-describe.bbclass: add new class for "git describe --tags --allways --dirty"

[Mikko Rapeli]

Output from git_describe() function can then be used in various places
and from various git trees to create a user friend(lier) name to builds.
Examples where this could be used is BUILD_ID, SDK_VERSION and
IMAGE_VERSION_SUFFIX.

This is for poky list, not core.

If you want to name your distro, make your own distro.conf.

You can trivially just include poky.conf as the first thing it does, but I do recommend that everyone using Yocto in production create their own distro and not piggyback on Poky.  Poky can, and does, change over time as it’s a test distro for QA purposes, and you may not want what we add.

I do think this should be part of lib/oe/buildcfg.py.

poky-tiny and poky-altcfg do this.

Just to be clear, you can create a distro.conf file even in a local
build directory where local.conf is.

We've kind of left the = assignments in poky.conf to nudge people in
this direction as creating a custom distro in local.conf isn't really
what we want to encourage.

It would be nice to somehow consolidate this new bbclass with
https://git.openembedded.org/meta-openembedded/tree/meta-oe/classes/gitpkgv.bbclass
https://git.openembedded.org/meta-openembedded/tree/meta-oe/classes/gitver.bbclass

and at least move the various git "wrapper" functions to lib/oe for better
reuse.

Re: [OE-core] [PATCH 1/2] poky.conf: allow changes to DISTRO_VERSION, SDK_VERSION and MAINTAINER

[Mikko Rapeli]

Hi,

Thanks for the feedback. My product isn't a real one, it's actually
some meta layers to be used
by others to create real products.

The reason for using poky.conf distro is to stay as close to it as
possible. But I still need to know
what is the output of my builds vs. something else from poky.

If chaning these veriables from local.conf is bad practice, then I
need to find other possibilities, like
the custom distro config (maybe move away from kas). But the aim is to
do as few changes to
poky as possible.

Cheers,

-Mikko

If all you want is for your values from your local.conf to be used, 
then you can use an override when setting the variables. In this 
case, since you want to override the values from the poky distro, 
why not use it as the override, e.g.:

DISTRO_VERSION:poky = "my-version"
