Re: [dpdk-dev] [PATCH v7 0/4] devtools: abi breakage checks

["Kinsella, Ray" <mdr@ashroe.eu>]

Hi David,

Came across an issue with this.

Essentially what is happening is that an ABI dump file generated with a newer versions of libabigail
is not guaranteed to be 100% compatible with a older versions.

That then adds a wrinkle that we need may need to look at maintaining abi dump archives per distro release,
or libabigail version depending on how you look at it. 

An alter approach suggested by Dodi would be to just archive the binaries somewhere instead, 
and regenerate the dumps at build time. That _may_ be feasible, 
but you lose some of the benefit (build time saving) compared to archiving the abi dumps. 

The most sensible approach to archiving the binaries.
is to use DPDK release os packaging for this, installed to a fs sandbox. 

So the next steps are figuring out, which is the better option between 
maintaining multiple abi dump archives, one per supported os distro. 
or looking at what needs to happen with DPDK os packaging. 

So some work still to do here. 

Thanks,

Ray K
