Mock hangs - why?
by Al Pacifico 26 Oct '06

26 Oct '06

I have fifteen CPAN packages that I'm packaging as RPMs for FC5, and one (and only one) of them seems to hang mock. Is this an appropriate place to ask for advice? Thanks. -al __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com

Mock going forward
by Clark Williams 07 Sep '06

07 Sep '06

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Ok, last unsolicited mock email of the day. Really! I promise... We're currently shipping mock from the mock-0.6 branch of the mock CVS repository. The HEAD (0.7) is the branch that contains the re-architected launcher and the elevate/drop privilege logic. I'm wondering when/how we push the new version of mock out to the world? My preference would be to wait for FC6 to go gold, then switch over to HEAD and deal with mock breakage at that point. Of course, the complete lack of complaints from all you dedicated fedora buildsys readers probably means that mock-0.7 is perfect in every way, so we probably don't have to worry about that, eh? :) Anyway, I'd be interested to hear what everyone thinks and I'd like to learn what the mechanism is for implementing it. Is implementation merely telling Jeremy or Jesse what branch to pull from? Or do we have to do more?

sparc weirdness
by Dennis Gilmore 19 Aug '06

19 Aug '06

Hey all, I have a odd situtation that im trying to work out the best way to handle. gcc on sparc needs glibc for sparc and sparc64 but it gets built as sparc. somehow i need to have sparc64 glibc in the buildroot only for gcc. even though the target is sparc. Dennis

Mock hangs - why

Sorry to post twice, but I need to correct what I just wrote, as the problem **HAS** changed following the kernel upgrade from kernel-smp.i686 2.6.17-1.2157_FC5 to kernel-smp.i686 2.6.17-1.2174_FC5: --- Al Pacifico <adpacifico(a)yahoo.com> wrote: > Date: Thu, 17 Aug 2006 16:59:09 -0700 (PDT) <snip> > > Dan- > I don't think that is the problem.

Repeated, with --debug, it seems to hang at the same place: DEBUG: Executing /usr/sbin/mock-helper chroot /var/lib/mock/fedora-5-i386-core/root /sbin/runuser - root -c "cd /;/sbin/runuser -c 'rpmbuild --rebuild --target i386 --nodeps /builddir/build/SRPMS/perl-DBIx-Migration-0.05-1.fc5.src.rpm' mockbuild" ...and after seeing that, I prematurely posted that the problem was uncorrected with a kernel update.

Thanks to Dan for sharing his experience and insights! With 'mock shell', however, the previously-described behavior persists despite the kernel upgrade. -al __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

mock SELinux policy as RPM package
by Hans Ulrich Niedermann 18 Aug '06

18 Aug '06

Hi, the question of a package of the mock SELinux policy from http://fedoraproject.org/wiki/Extras/MockTricks has come up a few times in the past, and I have made an RPM package for my own use some time ago: http://n-dimensional.de/software/mock-selinux-policy/ It doesn't have all the bells and whistles Paul Howarth has mentioned in http://fedoraproject.org/wiki/PackagingDrafts/SELinux/PolicyModules yet (my package predates that document by several weeks), but should be too difficult to adapt if someone is interested. (This is my second try to post here as my last message seems to have been eaten by the moderation system.) Gruß, Uli

Mock hangs - why
by Al Pacifico 17 Aug '06

17 Aug '06

I have fifteen CPAN packages that I'm packaging as RPMs for FC5, and one (and just one) of them seems to hang mock (mock-0.6-4.fc5). All of them check out with rpmlint and all build using rpmbuild. All SRPMs except 'perl-DBIx-Migration-0.05-1.fc5.src.rpm' build flawlessly with mock. But 'mock perl-DBIx-Migration-0.05-1.fc5.src.rpm' seems to hang. Adding the --debug option, the screen output (and root log) of 'mock perl-DBIx-Migration-0.05-1.fc5.src.rpm' ends with: Executing /usr/sbin/mock-helper chroot /var/lib/mock/fedora-5-i386-core/root /sbin/runuser - root -c "cd /;/sbin/runuser -c 'rpmbuild --rebuild --target i386 --nodeps /builddir/build/SRPMS/perl-DBIx-Migration-0.05-1.fc5.src.rpm' mockbuild" Then, the command prompt never comes back and when I interrupt mock with ctrl-C (I've left my machine running mock with this SRPM for over a day, so I don't think it's an impatience thing), keystrokes are retyped at the console after a long delay and many keystrokes, if at all. With my other 14 packages, if using the --debug option, this command is followed by the usual rpmbuild output at this point, the usual mock 'Results and/or logs in: /var/lib/mock/fedora-5-i386-core/result' message, and then the command prompt. I solicited advice from Jesse Keating who suggested trying the mock shell, and what I learned is that 'su - mockbuild' prompts for a password even though I'm in the chroot'ed shell as 'root'. What is puzzling is that this is before trying to rebuild the SRPM, so it's not that this package alters the behavior of mock (as I had previously thought). So, I tried the following (on Jesse's advice): [build@powell SRPMS]$ mock init init clean prep This may take a while ending done Finished initializing root [build@powell SRPMS]$ mock shell init mock-chroot> id uid=0(root) gid=501 groups=101,501 context=user_u:system_r:unconfined_t:s0 mock-chroot> su - mockbuild Password: su: incorrect password This leads me to believe that when I try to rebuild this SRPM using 'mock perl-DBIx-Migration-0.05-1.fc5.src.rpm', mock is prompting me for a password for user 'mockbuild' and therefore appears to hang. I have no idea why this does not happen with the other fourteen SRPM's and just with this one or when using 'mock shell'. Google offered a tantalizing clue on the fedora-selinux list (last post in the thread is at URL: http://listman.redhat.com/archives/fedora-selinux-list/2006-August/msg00073…) which described mock hanging at the same place on older versions of Fedora Core, related to older versions of selinux. Output of rpm -V mock is: [build@powell SRPMS]$ rpm -V mock S.5....T. c /etc/mock/fedora-5-i386-core.cfg [build@powell SRPMS]$ which is exactly what I'd expect, and other packages build fine under mock: [build@powell SRPMS]$ mock perl-Tie-RegexpHash-0.15-1.src.rpm init clean prep This may take a while setup build ending done Results and/or logs in: /var/lib/mock/fedora-5-i386-core/result ... so mock is not goofed up. My /etc/mock/default.cfg points to a slightly tweaked configuration script, which basically just changes the repositories to local mirrors. I've attached it to this message. Couple of questions: 1. Can someone check on his/her box that 'su mockbuild' from the chroot'ed shell has the same behavior and post back? 2. Would a mock guru out there have any suggestions? -al __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

Disttags in mock?

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Do we need to add a disttag to the mock specfile? My initial thought was no, since it's a noarch and pretty much should run on any python >= 2.2.
