JMAPCalendars.setcalendarevents_recurrence fails on 32-bit machines

[jasontibbitts]

So JMAPCalendars.setcalendarevents_recurrence fails on 32-bit machines. I thought I had all of these sorted but then I updated Cassandane and I guess this one was new. A full build log is at https://kojipkgs.fedoraproject.org//work/tasks/2341/20212341/build.log but it's just one test so I'll include all of the relevant output.

1) test_setcalendarevents_recurrence(Cassandane::Cyrus::JMAPCalendars)
 Structures begin differing at:
  $a->{recurrenceRule}{byDay}[0]{nthOfPeriod} = '-1'
  $b->{recurrenceRule}{byDay}[0]{nthOfPeriod} = '-2'
 at Cassandane/Cyrus/JMAPCalendars.pm line 604.

Test was not successful.

[rsto]

Thanks. I'll look into the this, but might have to set up a 32-bit environment to test this.

[jasontibbitts]

I can easily test patches and I'm happy to try something out or get additional debugging info or whatever you might need.

For my 32-bit testing, I just ask mock to build the Fedora package on i686 with the problematic test enabled, and then after it fails I just ask mock to fire up a shell in the chroot that's left. That way all of the cyrus and cassandane sources are there and set up to be run. Probably not the easiest thing for you to replicate unless you have a Fedora machine handy but at least Debian does have mock with the Fedora configs and I could give you some instructions.

[rsto]

I've set up a 32-bit test system using latest Debian, but ended up in CPAN-vs-Debian Perl madness. I haven't got Cassandane running locally.

That being said, could you please re-run the Cassandane test on your setup and send the RRULE line of the generated iCalendar file?

E.g. in my /var/tmp/cass directory where Cassandane keeps the test instance environments, I get

$ grep RRULE 115318A1/data/user/cassandane/#calendars/Default/1.
RRULE:FREQ=MONTHLY;COUNT=1024;INTERVAL=2;BYDAY=-2MO,SA;WKST=SU

[jasontibbitts]

Ah, fortunately Fedora has pretty much everything needed to run Cassandane. The one bit that isn't packaged (the test data out of Net-CalDAVTalk), along with Cassandane itself, is included in the cyrus-imapd source package. So a mock run brings everything in.

Edit: In case it matters, Fedora has libical 2.0.0. It's only lightly patched, but there is one patch which maybe could possibly be related: https://src.fedoraproject.org/cgit/rpms/libical.git/tree/libical-2.0.0-arm.patch
You can see all three patches at https://src.fedoraproject.org/cgit/rpms/libical.git/tree/

There are three RRULE lines in the generated icalendar file. If I start with a clean work directory and do

./testrunner.pl -f pretty JMAPCalendars.setcalendarevents_recurrence; grep -r RRULE work

I get

work/1405221/data/user/cassandane/#calendars/Default/1.:RRULE:FREQ=YEARLY;BYDAY=-1SU;BYMONTH=10
work/1405221/data/user/cassandane/#calendars/Default/1.:RRULE:FREQ=YEARLY;BYDAY=-1SU;BYMONTH=3
work/1405221/data/user/cassandane/#calendars/Default/1.:RRULE:FREQ=MONTHLY;COUNT=1024;INTERVAL=2;BYDAY=-1MO,SA;WKST=SU

I'll just give you the whole thing in case that's unexpected:

@jasontibbitts could you please cherry-pick this commit rsto@096984a and test in your setup?

[jasontibbitts]

Unfortunately that doesn't appear to make any difference at all; the output appears to be pretty much identical except for PIDs and random port numbers and such.

[jasontibbitts]

If you're still having issues getting a 32-bit environment set up but can install the 'mock' package on your distribution, you should be able to do the following:

• Make sure you're in the 'mock' group so that you can actually run mock.
• Make sure you have a pile of space in /var.
• Download https://www.math.uh.edu/~tibbs/cyrus-failures/cyrus-imapd-3.0.2-4.fc27.src.rpm
• Run mock -r fedora-rawhide-i386 --rebuild cyrus-imapd-3.0.2-4.fc27.src.rpm
• Wait.... this will init a chroot containing Fedora rawhide plus everything needed to build cyrus and run cassandane, then do the build and run all of the tests. For me it takes about three minutes, but I have a complete Fedora mirror in the next room.
• The build should error out on the setcalendarevents_recurrenct test and leave the chroot intact.
• Run mock -r fedora-rawhide-i386 --shell. This will drop you into the chroot.
• Run:

su - mockbuild
cd /builddir/build/BUILD/cyrus-imapd-3.0.2/cassandane
export CYRUS_USER=$USER
./testrunner.pl -f pretty JMAPCalendars.setcalendarevents_recurrence

The cyrus sources are one level up in /builddir/build/BUILD/cyrus-imapd-3.0.2, and you can tweak and rebuild as necessary. The only caveat is that if you want to install newly compiled stuff, you should do make install DESTDIR=/builddir/build/BUILDROOT/cyrus-imapd-3.0.2-4.fc27.i386 so that it gets put in the right place.

Oh, and if you need a package installed in the chroot, you can run mock -r fedora-rawhide-i386 -i strace vim or whatever (from outside the chroot).

@jasontibbitts thx, got it running. only thing: I can't seem to find where the syslog output goes. do you know?

[jasontibbitts]

Cool. Sadly syslog is a pain; it just isn't something that can properly work in chroots. I had tried writing an interposer for syslog functions but didn't have much luck. (I'm not very good at C, and I think the glibc syslog functions are macros anyway. But it's in that package as cassandane-redirect-syslog.c if for some reason you wanted to look at it. The specfile doesn't actually build or try to use it, though the gcc line is in there, commented out.)

However, mock can bind-mount things into the chroot. When I need to get output I add this to /etc/mock/site-defaults.cfg (though your distro may have moved it):

config_opts['plugin_conf']['bind_mount_enable'] = True
config_opts['plugin_conf']['bind_mount_opts']['dirs'].append(('/dev','/dev/'))
config_opts['plugin_conf']['bind_mount_opts']['dirs'].append(('/run/systemd/journal','/run/systemd/journal/'))

The third line is only needed if your system uses the systemd journal stuff; otherwise the first two lines should be enough to get your host /dev/log into the chroot so syslog output works. At least I think it should; Fedora uses the journal for everything so I'm basically guessing there.

Mock can also init containers instead of chroots and fire them off with systemd-nspawn but... I don't have a lot of experience with containers and so I've never tried to do any of that.
