"different contents" error when unembargoing security update or copying packages

[Marc Deslauriers]

When trying to unembargo a lucid security update from the security team PPA to lucid-security, I get the following:

mdeslaur@mdlinux:~$ $UQT/security-tools/unembargo $SRCPKG

AFAICT, the md5sum of gource_0.23.orig.tar.gz in the PPA, and the one in archive.ubuntu.com matches...

The files are the same, so that should be fine and not give an error.

I suspect the code is comparing the objects themselves, rather than doing a more clever comparison which is evidently needed. A workaround would be to upload the security update without the orig tarball, and that should copy fine. In any case, I am working on a fix currently.

Please do a cherrypick for this. We need to push out some urgent lucid-updates SRUs. Thanks!

[Martin Pitt (pitti)]

@SRU team: In case you try to push stuff to -updates, it doesn't work right now due to this.

[Julian Edwards (julian-edwards)]

A fix was cowboyed to cocoplum and Martin verified it works fine there.

The fix to the appservers (for web and API copying checks) will be delayed until we re-roll the mainline out in the next day or so.

[Max Bowsher (maxb)]

Also affects copying packages in PPAs, not unique to unembargoing

[Ursula Junque (ursinha)]

Fixed in db-stable r9334 <http://bazaar.launchpad.net/~launchpad-pqm/launchpad/db-stable/revision/9334>

[Marc Deslauriers (mdeslaur)]

I successfully unembargoed a lucid security update this morning, so this appears to be resolved. Thanks.
