We can't ask them to rebuild their entire toolchain each night! No OpenJDK either (can probably be fixed, but zero is sloow). Additionally, with only, say, 256 or 768 MiB physmem, running additional software on the buildds is something you do not want, considering how much RAM building some stuff takes (I had to use about 5 GiB of swap to link Webkit, and imagine just how much paging that involves, also in terms of time). Building GCC isn’t exactly resource-saving. (Even running apt/dpkg isn’t due to the sheer size of the archive, though Guillem kindly reduced memory usage in the upcoming dpkg upload.) I think with my “better SCC proposal” we could have a sliding scale for this, but I’d oppose using something OpenJDK-based for that (think of mipsel, too). Especially as simple mksh scripts would take care of the job too (including CGI for web export ;). bye, //mirabilos -- Solange man keine schmutzigen Tricks macht, und ich meine *wirklich* schmutzige Tricks, wie bei einer doppelt verketteten Liste beide Pointer XORen und in nur einem Word speichern, funktioniert Boehm ganz hervorragend. -- Andreas Bogk über boehm-gc in d.a.s.r -- To UNSUBSCRIBE, email to debian-sparc-requ...@lists.debian.org with a subject of "unsubscribe".

This is a more serious problem than resources needed by Jenkins. We can't ask them to rebuild their entire toolchain each night! For the goal of software freedom, it shouldn't be too difficult for anyone to do that, though. We should be trying to make it easier. Maybe it would be permissible for the toolchain test suite to run on a faster platform, and cross-compile, or use any sort of emulation available in Debian free packages. If it were technically feasible for each Debian port to rebuild its toolchain and some essential packages, at least once per week, I think that would be an accomplishment. And the smaller the initial set of packages required to boostrap the process, the better. Regards, -- Steven Chamberlain ste...@pyro.eu.org signature.asc Description: OpenPGP digital signature

I haven't recently seen a slave jenkins java process more than one or two hundred mb. This is (of course) absolutely insane, as is the 4-6GB jenkins master process. However, dollars per GB of memory is suitably low that it's not worth me fixing it, instead it just sits there annoying me as it could undoubtedly be better -- Stewart Smith pgpBBYdyNkP40.pgp Description: PGP signature

That may be useful to set up on some arches, for things where Jenkins needs direct control over CPU-intensive tasks. Building and testing d-i, for example. But for this, I would imagine only the test suite needs to run over SSH, and the master Jenkins instance just has to process the output? For the proposed test suite to be as accessible as possible to a new/upcoming port, the barrier to using it ought to be very low. A working JVM is quite a lot to ask, the current openjdk-7 is not even built for mipsel in more. mipsel buildds and porterboxes had only 1GB RAM maximum until now, and that is heavily used already for their current tasks.

Small is 64m ram not 256m. I just woke up and was catching up on things. My
apologies.

Re: Bits from the Release Team (Jessie freeze info)
I run Jenkins at my job. Small is around 256mb. Plus the Jenkins server can
sit on a high-memory machine and the agent just sit on a 68k box doing
builds. Small is like 64M ram. You Amiga/Atari guys seem to have oodles of
ram to work with Lol.
