Corpus structure
================
ceph.git/ceph-object-corpus is a submodule.::
bin/ # misc scripts
archive/$version/objects/$type/$hash # a sample of encoded objects from a specific version
You can also mark known or deliberate incompatibilities between versions with::
archive/$version/forward_incompat/$type
The presence of a file indicates that new versions of code cannot
decode old objects across that $version (this is normally the case).
How to generate an object corpus
--------------------------------
We can generate an object corpus for a particular version of ceph like so.
#. Checkout a clean repo (best not to do this where you normally work)::
git clone ceph.git
cd ceph
git submodule update --init --recursive
#. Build with flag to dump objects to /tmp/foo::
rm -rf /tmp/foo ; mkdir /tmp/foo
./do_autogen.sh -e /tmp/foo
make
#. Start via vstart::
cd src
MON=3 OSD=3 MDS=3 RGW=1 ./vstart.sh -n -x
#. Use as much functionality of the cluster as you can, to exercise as many object encoder methods as possible::
./rados -p rbd bench 10 write -b 123
./ceph osd out 0
./init-ceph stop osd.1
for f in ../qa/workunits/cls/*.sh ; do PATH=".:$PATH" $f ; done
../qa/workunits/rados/test.sh
./ceph_test_librbd
./ceph_test_libcephfs
./init-ceph restart mds.a
Do some more stuff with rgw if you know how.
#. Stop::
./stop.sh
#. Import the corpus (this will take a few minutes)::
test/encoding/import.sh /tmp/foo `./ceph-dencoder version` ../ceph-object-corpus/archive
test/encoding/import-generated.sh ../ceph-object-corpus/archive
#. Prune it! There will be a bazillion copies of various objects, and we only want a representative sample.::
pushd ../ceph-object-corpus
bin/prune-archive.sh
popd
#. Verify the tests pass::
make check-local
#. Commit it to the corpus repo and push::
pushd ../ceph-object-corpus
git checkout -b wip-new
git add archive/`../src/ceph-dencoder version`
git commit -m `../src/ceph-dencoder version`
git remote add cc ceph.com:/git/ceph-object-corpus.git
git push cc wip-new
popd
#. Go test it out::
cd my/regular/tree
cd ceph-object-corpus
git fetch origin
git checkout wip-new
cd ../src
make check-local
#. If everything looks good, update the submodule master branch, and commit the submodule in ceph.git.
