using pbuilder (instead of cowbuilder)

[lurdan]

Please provide options to switch between builders.

Though tt seems that j-d-g assumes build tool is cowbuilder only, I want to use pbuilder on slave kfreebsd node... (cowbuilder doesn't support that architecture)

[mika]

Can you please provide details about your setup, like:

• How does your pbuilder configuration (pbuilderrc) look like?
• How do you invoke pbuilder (manually)?

[lurdan]

Master node: amd64 box, build-and-provide-package successfully builds amd64/i386 using cowbuilder. /etc/pbuliderrc only sets MIRRORSITE.

Slave node: kfreebsd-amd64 box, set up as faq/#foreign_arch_builds. Combination settings calls this node for kfreebsd arch, and build-and-provide-package fails (because of lacking cowbuilder on kfreebsd). /etc/pbuilderrc sets MIRRORSITE and USEDEVFS=yes (which is requirement for kfreebsd arch.) Also, I can execute pbuilder manually and it successfully builds packages on kfreebsd node.

[mika]

Ok, I see. Could you please be so kind and share the command lines you used to set up the initial pbuilder environment on the kfreebsd-amd64 box (pbuilder --create ...) and which cmdline(s) you're using for building (pbuilder --build ...)? If I can reproduce your environment I might be able to provide the according pbuilder integration in j-d-g.

Because I've used long living old image for manual pdebuild, so I've tried some test.

On the kfreebsd-amd64 box (sid):

$ sudo pbuilder --create --basetgz base-sid-kfreebsd-amd64.tgz
$ sudo pbuilder --create --architecture kfreebsd-i386 --basetgz base-sid-kfreebsd-i386.tgz 

will make the base taballs. It requires USEDEVFS=no in pbuilderrc. Without it, --create fails its last stage mounting /dev.

When building packages with images created above,

$ sudo pbuilder --build --basetgz base-sid-kfreebsd-amd64.tgz package.dsc
$ sudo pbuilder --build --basetgz base-sid-kfreebsd-i386.tgz  package.dsc

will work fine. But this time it requires USEDEVFS=yes in pbuilderrc. Without it, build fails because it can't mount /dev.

I don't know in details, though its odd behavior seems to be related to this bts... http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=630813

I see, thanks for providing the instructions, I'll see whether I can locate time to implement pbuilder support for it.

Hi, I'd lke to use dpkg-buildpackage as builder for deb, when use docker as jenkins slaves.

As far as I know, multiple instance of pbuilder running at the same time could lead some problems. I think I could avoid it with dpkg-buildpackage and docker.

[mika]

Multiple instances of cowbuilder at the same time aren't a problem, there's just one problem with multiple instances running the "--update" option at the same time, I tried to address that in branch mika/flock (ping @zeha) though I haven't had the time to verify that yet.

JFTR: I welcome any patches adding support for further build tools.

I also would like pbuilder support, since I want to mount a tmpfs at /var/cache/pbuilder/build. Cowbuilder tries to use hardlinks, which won't work across filesystems.

[mika]

@heftig what you can do though is using whole /var/cache/pbuilder/ in a tmpfs (which I'm doing, and by using an rsync script to disk running between reboots it's getting persistent)
