Tests failure on Debian stable on ARM

Here's the full list, will dive into them as we go along.

This first one is because:

      res = lzma_easy_encoder (&self->lstream, 8, LZMA_CHECK_CRC64);

fails with LZMA_MEM_ERROR, and the LZMA compressor fails to send the send back an error, sends 0 instead.

OSTree:ERROR:tests/test-lzma.c:50:helper_test_compress_decompress: assertion failed (n_bytes_written > 0): (0 > 0)

MALLOC_CHECK_=2 MALLOC_PERTURB_=48 ./tests/test-lzma

To reproduce on an affected system.

gcc version 4.9.2 (Debian 4.9.2-10)
model name : ARMv7 Processor rev 2 (v7l)

1. Only fails deep within liblzma with MALLOC_CHECK_=2 MALLOC_PERTURB_=48 set, so I'll chalk this off as a failure in that code, though limiting the amount of maximum RAM used by that code throws up an actual failure on x86-64.
2. Fails because the $PATH is incorrect to locate ostree:

VERBOSE=1 make check-TESTS TESTS=tests/test-basic.sh
<snip>
++ test -n ''
++ test -z ''
++ CMD_PREFIX='env LD_PRELOAD=/home/chip/ostree-2016.6/tests/libreaddir-rand.so'
+ setup_test_repository bare
+ mode=bare
+ shift
++ pwd
+ oldpwd=/var/tmp/tap-test.HwxkgF
+ cd /var/tmp/tap-test.HwxkgF
+ mkdir repo
+ cd repo
++ pwd
+ ot_repo=--repo=/var/tmp/tap-test.HwxkgF/repo
+ export 'OSTREE=env LD_PRELOAD=/home/chip/ostree-2016.6/tests/libreaddir-rand.so ostree --repo=/var/tmp/tap-test.HwxkgF/repo'
+ OSTREE='env LD_PRELOAD=/home/chip/ostree-2016.6/tests/libreaddir-rand.so ostree --repo=/var/tmp/tap-test.HwxkgF/repo'
+ test -n bare
+ env LD_PRELOAD=/home/chip/ostree-2016.6/tests/libreaddir-rand.so ostree --repo=/var/tmp/tap-test.HwxkgF/repo init --mode=bare
env: ostree: No such file or directory

The fix looks to be:

-       PATH=$$(cd $(top_builddir)/tests && pwd):$${PATH} \
+       PATH=$$(cd $(top_builddir) && pwd):$${PATH} \

(Which might mean that it's the OS-installed ostree that might have been tested up until now)

1. I can't reproduce the bug stand-alone yet.
2. is the same as 1, OOMs

And I'm going to say that guess that most of the other failures are due to the 512 megs of RAM on my test system.

Fails because the $PATH is incorrect to locate ostree

I'm fairly sure I fixed that in ca899cc and 0ed9f52? The build system is meant to put a symlink ostree → ../.libs/lt-ostree (or whatever the real binary is) in the tests/ directory.

[smcv]

I'm hoping to get an official Debian backport of OSTree and Flatpak going at some point, but there are still several yaks to be shaved between here and there: by policy, official backports come from testing, and OSTree can't migrate from unstable to testing until it builds successfully on all architectures where it has previously built, including mipsel where ostree pull sporadically fails with a bus error and no useful backtrace.

When that exists, you'll be able to install ostree_2016.6-42~bpo8+1 (or whatever version it is) from the jessie-backports suite, instead of having to compile your own on an underpowered board.

FYI, that's the test system, if someone wants to get it into their CI ;)

Ignore my comment about 2., not sure what I was doing then.

It looks like the LZMA thing is an independent bug, I'll split that out. But where are we on the rest of this?

It looks like the LZMA thing is an independent bug, I'll split that out.

I couldn't find a bug for this one, so I filed:
#440

But where are we on the rest of this?

With libsoup and ostree master, I still get hangs and crashes as mentioned in:
#381
which should probably be reopened, and/or requirements updated to match.

With libsoup, ostree and flatpak master, it hangs trying to install the fd.o runtime:
