It's not caused by this change, but fixing this issue revealed that
fc-cache doesn't really work here.

Every time the intercept_scripts/update_font_cache executes qemu it gets
"stuck" eating a lot of cpu and memory until it dies. Is anyone alse
seeing this behavior?

There are a couple of bugs in the bugzilla around this. One seemed to be
related to circular symlinks in udev's ptest package which was
supposedly fixed. The other claims to have been resolved by upgrading
fontconfig to a version which doesn't have issues with circular paths.

There is general confusion about how to reproduce the issue and what the
real problem is though.

Does your system have any recursive directory structures?

I'd like to get to the bottom of the issue and fix it once and for all
but we likely need more info.

Cheers,

Richard

I've tried to build a bit smaller image after sending the report and in
that do_rootfs it finished successfully. I'll try to re-execute this to
see if I get consistent results.

The bigger image has only few more packages in it, so if this is the
case and smaller always works while bigger always fails I should be able
to quickly find out which package/file is causing this.

I'll check the circular symlinks, I know there are some ptest packages
in the bigger one.

In my case it's reproducible by adding udev-ptest to image, more specifically
having these 2 directories in rootfs:
usr/lib/udev/ptest/test/sys/devices
usr/lib/udev/ptest/test/sys/bus

deleting them and re-triggering the qemu works.
I can also confirm that it's not just lack of memory on the build machine.
It triggers OOM killer after using 64GB as well as on machine with just 8GB.

fc-bug/rootfs-broken$ time ../../../../sysroots/x86_64-linux/usr/bin/qemu-i386 -r 2.6.32 -L . -E LD_LIBRARY_PATH=usr/lib:lib usr/bin/fc-cache --sysroot=.
... OOM killer in an hour or 2 ... (this time I didn't get a log, because it killed almost everything else except qemu-i386 :)
fc-bug/rootfs-broken$ cd ..
fc-bug$ cp -ra rootfs-broken rootfs-broken-without-udev-ptest-bus-devices
fc-bug$ cd rootfs-broken-without-udev-ptest-bus-devices
fc-bug/rootfs-broken-without-udev-ptest-bus-devices$ rm -rf usr/lib/udev/ptest/test/sys/devices/ usr/lib/udev/ptest/test/sys/bus/
fc-bug/rootfs-broken-without-udev-ptest-bus-devices$ time ../../../../sysroots/x86_64-linux/usr/bin/qemu-i386 -r 2.6.32 -L . -E LD_LIBRARY_PATH=usr/lib:lib usr/bin/fc-cache --sysroot=.

real    0m30.424s
user    0m29.714s
sys     0m0.548s

Comparing strace shows the broken one to cycle a lot in directories like this:
< getdents(51, /* 8 entries */, 32768)    = 248
< openat(AT_FDCWD, "//home/jenkins/anaconda/build-starfish-dizzy/build/BUILD/work/qemux86-starfish-linux/fc-bug/rootfs-broken/./usr/lib/udev/ptest/test/sys/dev/block/8:1/subsystem/loop2/bdi/subsystem/0:16/subsystem/0:16/subsystem/0:16/subsystem/0:16/subsystem/0:16/subsystem/0:16/subsystem/0:16/subsystem/0:16/subsystem/0:16/subsystem/0:16/subsystem/0:16/subsystem/0:16/subsystem/0:16/subsystem/0:16/subsystem/0:16/subsystem/0:16/subsystem/8:16/subsystem/8:0/power", O_RDONLY|O_NONBLOCK|O_DIRECTORY|O_CLOEXEC) = 52

This issue forced me to finally set ulimit in my builds so that I can kill the
right process a bit sooner (instead of waiting for it to eat e.g. 128GB)

I'll try to create smaller reproducer and check newer fontconfig.

oe-core 3f799b should mean that those directories are in a tarball instead
of unpacked on the rootfs.  Do you have that commit?

Oh, thanks for pointer. I was seeing the same issue in dizzy and master
build, but this change can explain why I wasn't able to reproduce it in
master yesterday.

Sounds like we should backport that to dizzy (CCing Armin).

yes, I've verified that I can reproduce this issue in master after
reverting this change and that it resolves the issue in dizzy if I
backport it with one other change (just to apply it cleanly with
additional bugfix), I've referenced the fontcache.bbclass fix, these
3 should go in only together.

My bigger image build is still running, but this fix is definitely
helping.

So I just managed to replicate and root-cause this a bit.   Good news:
found this in qemu's bugzilla.  Bad news: it's been open since 2013.

https://bugs.launchpad.net/qemu/+bug/1245703

The startup code iterates all files in the "sysroot" and cyclic symlinks
cause it to iterate forever.  So for now the official advice is "don't have
cyclic symlinks in your rootfs, or qemu breaks".

I've found the reason why it was failing for me in master even with this
udev fix when building our internal images.

The problem is that we have fontconfig bbappend which sets:
WEBOS_FONTCONFIG_CACHE = "${datadir}/fontconfig/cache"
EXTRA_OECONF_append = " --with-cache-dir=${WEBOS_FONTCONFIG_CACHE}"

and this oe-core commit:
commit 23393c6685860d0b1c459874d35395360d0b6d3c
Author: Jonathan Liu <net147@gmail.com>
Date:   Mon Mar 9 13:28:37 2015 +1100

    postinst-intercepts/update_font_cache: fix ownership of fontconfig cache
 
adds:
chown -R root:root $D${localstatedir}/cache/fontconfig

Which doesn't exist in our builds and chown and whole postinst
interceptor fails.

I'll send patch to make fontconfig cache dir configureable so that we
don't need to overlay fontcache.bbclass as well as
scripts/postinst-intercepts/update_font_cache

So how is fontconfig told to read fonts from this location?

I think it's the same
--with-cache-dir
parameter which says where to generate the cache and then read it in
runtime.

I didn't change it in fontconfig recipe, because the default is already
matching with FONTCONFIG_CACHE_DIR, do you want me to pass
--with-cache-dir parameter? I agree that it could be less surprising for
people who want to change it, but on the other hand if upstream moves
default cache location in some newer fontconfig version, then the person
updating the recipe should check FONTCONFIG_CACHE_DIR value as well.

This looks better but what sets fontconfigcachedir ?

It's passed in intercept call in fontcache.bbclass like other variables
used here.

People who want to change the value should do so from global scope, so
that the same value is used in fontconfig_2.11.1.bb and
fontcache.bbclass.

Once this is merged in master, I would like to see it in dizzy (and
fido) branches together with other fontconfig related fixes.

Thanks

The other fontconfig related fix:
fontcache.bbclass: prepend to PACKAGEFUNCS instead of appending
was merged to dizzy recently, so now dizzy is broken for us, because
this one (and the one fixing permissions) are missing :/.

Do you expect more changes for this patch or was my explanation enough
to get it accepted?

I'm sure there's a good reason why fontconfig caches are going in datadir
but I'm not sure I want to know it :)

They're directory-wide caches, and caches tend to go into /var/cache.

I've replied to Ross off-list because I'm not sure how much details I
should share, but basically we have read-only rootfs which has all the
font packages installed, so cache from do_rootfs should remain valid
forever. And we delete everything in /var during reset to factory
settings (that's why we had to move everything which we want to persist
during factory resets like this cache).

We also have additional fontconfig patch which ignores timestamp
modifications in font directories, so that the cache is considered valid
even after some manual modification in rootfs (e.g. in devel images
which can be switched to read-write mode).

may be copy-binds could be deployed ?

We have that but IIRC copy-binds are mounted after or at the same time
the UI is starting in our upstart scripts (to show UI as soon as possible)
and we don't want to wait for copy-binds to be finished before loading fontconfig cache.
