[Fedora-electronic-lab-list] Retire Alliance RPMS on non ILP32 platforms

[Mukund Sivaraman]

Hi Chitlesh

I advise you to retire Alliance RPMS from non ILP32 distributions such
as x86_64. Alliance code has behavioural problems which manifest
themselves on such platforms. There are no compile-time warnings for
some of these issues, and tools can behave in a non-deterministic
manner.

We are fixing these problems as we find them in Herb, but it will still
be a while before Herb releases are made.

Hi Mukund,

Could you please test real examples on both i386 and x86_64 and show where the 
results diverge ?
Having these concrete results, we'll discuss it with upstream and see how we 
can fix it for alliance.

Regards,
Thibault

Hello Mukund,

I would recommend you to give us some details about those behavioural
problems. A fedora contributor gladly offered me  access to his x86_64
machine via ssh. Based on your details, I could carry out the testing
and report back to you.

Since currently Alliance can be easily deployed and herb is not, i
think for you it would be better to use alliance as a testbed and port
eventual back to herb. FEL users can also report back or confirm
eventual issues since they can easily install it. In the long run, it
will help you optimize herb's state. At the same time, the sooner we
will have a herb release.

Kind regards,
Chitlesh
