OSTree Support

Irrelevant gibberish. See helpful comments by ipanova below.

Jeremy, This issue was submitted and fixed against master branch. You rolled back the platform to 2.7dev but your ostree plugin still points to master. you need to checkout the branch to 1.0dev

[ipanova@ina pulp_ostree]$ git checkout master 
Switched to branch 'master'
Your branch is up-to-date with 'upstream/master'.
[ipanova@ina pulp_ostree]$ git grep SharedContentUnit
plugins/pulp_ostree/plugins/db/model.py:from pulp.server.db.model import SharedContentUnit

plugins/test/unit/plugins/db/test_model.py:        with patch('pulp.server.db.model.SharedContentUnit.pre_save_signal') as base:
[ipanova@ina pulp_ostree]$ git checkout 1.0-dev

Also check explicitly here what version of pulp-ostree plugin pulp2.7 uses https://repos.fedorapeople.org/repos/pulp/pulp/testing/automation/2.7/dev/fedora-23/x86_64/ ( which was build from 1.0dev branch )
And here the pulp2.8 uses pulp-ostree-plugins-1.1.0-0.5.beta.git.1.44a7bbe.fc23.noarch.rpm which points currently to master https://repos.fedorapeople.org/repos/pulp/pulp/testing/automation/2.8/dev/fedora-23/x86_64/

OK. I'll check out the 1.0dev branch as part of the rollback process.

Also check explicitly here what version of pulp-ostree plugin pulp2.7 uses [...]

I see that all three of the ostree packages (python-pulp-ostree-common, pulp-ostree-admin-extensions and pulp-ostree-plugins) have an identical version number. Is this always the case, or might they ever differ? Assuming they may differ, should I always refer to the pulp-ostree-plugins package when determining the canonical version of ostree present in a Pulp release?

Should have same version number.

Should have same version number.

OK. Thank you.

Thanks for this advice. It's allowed me to more intelligently install the appropriate plugin versions:
