Drop Ruby 1.9.2 support

Development
1

We currently support Ruby 1.8.7, 1.9.2 and 1.9.3 (soon 2.0.0 too), but
there's a problem showing up with 1.9.2 and Puppet 3.2.0-rc1, released
yesterday.

http://projects.theforeman.org/issues/2413

It's due to monkey patching of Array in Puppet, and it's conflicting
somehow with sass-rails in the full Foreman app (as we load Puppet as a
library). Unfortunately 1.9.2 is not a supported version for running
Puppet.

1.9.2 is only available on Debian Squeeze (of our primary platforms),
and even then, 1.8.7 is the default stack.

Does anybody object if we drop 1.9.2 support from the test matrix?

There was a proposal to drop 1.8 entirely a while back, which means for
Squeeze users we'd have to fix this. If we're keeping 1.8.7 for a decent
time frame, then I have no objection to dropping 1.9.2.

That said, we need strip back how we load the puppet libraries at some
point anyway, right? Should we not fix this and keep our options open? How
many people (at a guess) are affected by this today?

Good point, I think we'll be continuing 1.8 as long as Squeeze is
around. So maybe 1.3 could be the last?

We do, but I'm not sure it's in our priority list for 1.2. Maybe it
should be.

It only affects us at the moment as it's beginning to break tests. When
Foreman 1.2 is released, if we haven't removed Puppet from core, then it
will affect Puppet 3.2 users on Squeeze.

There's no guarantee people will upgrade when Wheezy is released. In $last
job I was supporting Squeeze, Lenny, Etch, and even a handful of Woody
systems. Admittedly asking them to upgrade just the Foreman server isn't
too bad, but still…

I wasn't suggesting that, I'm saying that we will get to it, and right now
no-one is impacted anyway (as far as I'm aware)

Then I propose we drop it from tests. Squeeze can be 1.8.7 as the official
platform, and 1.9.2 becomes a "best_effort" untested release. Replace 1.9.2
with 2.0 once we support it, then we're not increasing the test load.

Don't forget that CentOS (and 'stuff' like it) is also used quite a
lot and I see no support for any updated ruby 1.9.x version there in
the near future.

rhel5.x is 1.8.5. I (and I assume most opensource puppet users as well)
use the ruby 1.8.7 RPMs provided by PL.

el5.x is going to be with us until ~2017 and I suspect I'll be stuck
with it in my production env past that.

That and Ubuntu Lucid Lynx LTS 12.04, which will be a supported OS
until April, 2017, ships with 1.8.x. (Don't know if we can actually
support it that long, but we should try). Also RHEL is still shipping
with 1.8.x.

I didn't forget! Foreman 1.2 packages will probably be using SCL
(Software Collections) to provide a Ruby 1.9 stack on EL5 and EL6, which
Foreman will run under:

That's a good point, though we currently only primarily support the
latest LTS release (having stopped 10.04).

Anyway, I hadn't meant to cast a shadow over 1.8, apologies. I agree
that's the more important platform at the moment. 1.9.2 was the version
I was targeting!

I don't doubt it, been in the same situation myself plenty of times.
I'd always make a distinction though between minimum requirements to
deploy a new version of an application (e.g. Foreman 1.2) and keeping
requirements the same for an existing application (1.1.x). So I'd say
it's reasonable to require a current OS release to deploy a new
application release.

I didn't mean to suggest you did :slight_smile: I was just thinking of timescales,
as 1.2 will be out soon, as will Puppet 3.2, so that's when problems may
begin.

Yep, thanks. It's likely we can add 1.9.2 again if needed later, once
Puppet's removed, though we'll see when it happens.

Yeah, it should solve a few problems, maybe create some too!

Sam, reading Joshua's previous e-mail makes me wonder how we'll handle
Puppet in an SCL build of Foreman, since this is currently required from
Foreman core. Any thoughts, or are we consigned to rebuilding it…?

Yes, right now we are building 3.1 on top of the SCL. Unfortunately there
isn't much of a way around this because Foreman and puppet need to share
the same runtime in order for Foreman to load the required pieces of
Puppet's library.

All I know about SCL is from the slide deck Dominic sent around but…

If the SCL macros are added into the PL puppet/puppet-server RPM specs,
shouldn't it be possible to install an official opensource release into
the foreman SCL stack?
