[gentoo-dev] Suggestion: support the Dev team with system resources

[Denis M.]

[-- Attachment #1: Type: text/plain, Size: 3021 bytes --]

Hello gentoo-dev@,

Starting with a little intro, I'm currently providing a Gentoo VM to a
gentoo dev (Agostino Sarubbo (ago)) for the purpose of
testing/stabilizing/keywording packages, which is part of his task as a
developer and being part of the AT team. I've been running the VM for
him for a couple of months now and AFAIK he's been giving it a great use
;-).

The main idea here is to allow Gentoo contributors and members (not
necessary) of the Gentoo community, to be able to support the developer
team providing their spare system resources, by, for example, running a
Virtual Machine (or any sort of xen, kvm, virtualbox, vmware,
whatever...) instance where the devs can run tasks they'd normally
wouldn't be able to run with their systems, because:

* They're doing some other tests at the moment
* They're on ~arch and need stable
* They're not on the architecture needed for that testing
* Their system is not 'powerful' enough
* etc...


The purpose of doing this is that the developers that have the time and
dedication would be able to run a couple of different tests
concurrently, on different 'instances' provided by the community. That
will greatly, IMHO, improve the team's performance and not only in the
AT field.

The instances provided wouldn't forcefully need to meet any specific
minimum requirements (this would be decided once (and if) this gets
accepted), but a dual core system with 512MB ram would be somewhat an
acceptable instance for the bigger arches (x86 & amd64), and maybe lower
specs for the other arches[1]. As an example here, I'm giving Ago a
VirtualBox VM with 2GB ram and 4 virtual CPUs.

Also, for the contributors there shouldn't be any minimum uptime to
meet, they'll run the instances the time they use their systems, and if
they leave them idle all day/night that would just be better, although
they should be able to specify to the team normally the hours their
systems would be usable by the devs.

There should be a list of users that are able to share their resources
and each dev(s) would be given a certain number of instances depending
on their needs and such.

I know that you might think that doing this will lower the contributor's
desktop experience (as VMs tend to be somewhat heavy while compiling).
The usage of the AUTOGROUP kernel scheduler and cgroups tends to make
the desktop very much usable under high CPU pressure.

Please review this, and if you agree that it'd be a good idea come with
any suggestions to make it happen as well as with any other
thoughts/sys-specs/instances we should be looking for. If you don't
think this is a good idea or that it won't profit the Gentoo dev team,
please tell me why.

on the other arches and the resources they need.

I appreciate the idea, but security-wise it's pretty dangerous - given that 
you as a Gentoo dev are doing sensitive work that may affect many people on a 
machine not controlled by you yourself nor Gentoo Infra.

Call me paranoid, but please no. And in absolutely no case one should commit 
to the tree from such a machine, even with stuff like agent forwarding.

I completely agree with this, but it's not entirely true. Why? I'll give
the example of the AT team:

1. You sync the tree before you start your work (that way you verify the
tree is clean).
2. Then you start testing the packages or bugs you're after, which in
matter of security is meaningless because testing packages is usually
just compiling and running to see if it works as expected.
2.1. Apply random patches to fix if there's an issue.
2.2. goto 2.
3. etc...

I see no issue in this in matter of security.

Another example would be devs testing packages under development
(internal usage in gentoo), for example how new versions of
openrc/systemd/glibc/whatever can affect X.

I do understand your concern, although I wouldn't call you paranoid as
it's just normal to not trust a system that's not completely under your
control, but as I said, you don't really... 'care' about it/that.

Of course! Commiting or any other form of direct communication with the
gentoo infra. (either commit to tree or `git push`-ing to any of the
other gentoo repos) would be highly discouraged, and I didn't, in any
moment, think someone would think of doing that :P.

The idea behind this is using the provided instance only and exclusively
for testing something you'd normally can't do on your system.

Thanks for the offering. Though not a member, AT teams might benefit
from such a build farm.

What are you suggesting practically, making a policy for everyone to
donate VM to Gentoo, or developing a midware to do so?

Almost every Gentoo dev that does software testings of some sorts could
benefit from these "build farms" (although I'd refrain from using that
term ;) ..).

My initial idea was to suggest this here (in the gentoo-dev@ ML) first
and see what you guys think about the idea. If it gets accepted by
majority, then a policy, rules, etc... should be gathered through your
comments here. After that we could make a wiki page (as Ago suggested
while we were talking about this in IRC) and spam the gentoo-user ML and
see how many good people are there :-).

Don't let me put a damper on your plans as-is, but I'd be interested
if developers who frequently perform these kinds of tasks post about
what they're actually doing.

Rather than just asking people to give random others ssh access to
random boxes, it might make sense to streamline certain tasks.
Imagine a tool that takes in a list of atoms and dumps a tarball of
build logs in some standard layout.  That could be easily distributed
(assuming packages were reasonably independent), and tools like tatt
might even be adapted.

Not a reason to delay what you propose, just another opportunity.

I guess nobody wants to try and setup a VM-image-based heterogeneous

Rackspace (where I work) currently has a developer discount program.  I
think we also host some open source stuff for various projects.  Right
now you can try to use http://developer.rackspace.com/ but if we want to
make this more official I can ask around.  Let me know if we want this
as a more official thing (rackspace donating compute resources), no
guarantees though :D.

To be honest, I would like Gentoo infra to come up with a solution
sometime... Last time (a year ago) i asked them about this, they said
they have a cluster/big box for this purpose but they just didn't have
the time to deploy it properly or something.

iirc, we give $200 if infra for developer accounts for a couple of
months.  If a deal is struck it would likely be more and forever or
something.

Can't argue with that.  :)

Seriously, though, I'd love to see these needs better supported.  I
think we need to start by defining what the needs actually are (less
redundancy, more consistency, etc).  Then we figure out how to best
address them.  It could be individuals donating VMs, or it might be
Gentoo buying resources from any number of vendors, or it could be
Gentoo going out and looking for donors.  I suspect that if we went
out with something specific in mind we might be able to find a sponsor
- but it is always best to have some idea just what we're going to be
using any donations for (this will be our stage3 builder which cranks
out a new stage3 every 20 minutes and reports build failures to double
as a tinderbox, etc).

Currently Diego's tinderbox does something like that AFAIK. Compiles
things and (almost?) automatically submits bugs against the packages
with the relevant logs, etc...

The initial idea behind my suggestion was that the devs would have the
enough system resources to address these bugs (and the ones reported
from the users, of course).

An example here could be the following: finding/confirming a compilation
bug for a package with ~10 USE flags could take tatt quite some
compilations depending on the USE flag's combinations (this is actually
what arch testers do in order to stabilize/keyword a package). Another
example would be, as I mentioned in my previous mails to this thread - a
new glibc version comes out and (as you know) quite some packages fail
to compile against it. Having the resources, it would be possible to
track these packages faster instead of relying on random users/testers
to report them to bugs.g.o. And a last one would be testing new
KDE/GNOME/whatever-meta-with-huge-number-of-packages.

As an AT member myself I could only give examples on how using such
system of donating/providing instances would be a benefit. For a
comprehensive list of the tasks (for consistency as you said), I'd wait
for actual devs to enumerate their needs.

I doubt this will go as further as Gentoo actually *buying* resources.
The reason is obvious - "things have been going fine till now, why throw
monnies for something as 'unnecessary'" (which is why I haven't received
a penny for it, hehehe), that's why I came with the
donorship-of-instances version. I believe the 'going out looking for
donors' part you said is basically what I'm suggesting here, although I
believe you meant donors = huge companies providing clusters, and I
doubt that'll happen.

From my observation, you can get a lot of work done on a simple
2GB-ram-4-cores VirtualBox VM. Not to talk that lots of people nowadays
have these resources to spare. That's why getting actual people (and not
companies or whatever) to donate their system resources is easier to
get/reach.

I agree with that. It's easier to decide what to do if we know what we
need. A solution built by the infra team would be the best solution
for the same reasons why it's better to put stuff on the devspace
instead of private servers (availabilty; who can fix stuff, logins, etc).

But if someone need resources and a box to play with I would happily
provide an Xen instance. Just wondering: How is the AT for $minorarch
done? Is it possible to run, say, mips on xen/whatever through some
emulation layer or is real hardware a requirement for this archs?


For the security concerns: I think these boxes should be used for
testing only and not for development - every commit must be done from
a box fully under the dev's control.

Yes, via qemu. But very slow, nearly unusable even on a powerful
mainstream amd64 server.

Usually it is done via qemu, but as was said - it is damn slow. I use
qemu for emulating ARM device for compilation, cause it's faster than
compile on device(Raspberry Pi) itself mostly because of I/O.
