Bug Description

The hyperlinks to this project don't work, and the bzr download URL does not work with 6 different versions of bzr that I've tried from Windows and Mac.

bzr: ERROR: CHKInventoryRepository('')
is not compatible with
different rich-root support

Hi David,

Which hyperlink are you referring to?

I will look into the bzr error.

Well, I presume the hyperlinks he's talking about are those from <> such as <>.

The basic cause of the failure here is that the trunk has been upgraded and this branch hasn't been, and they're in an inconsistent state.

One solution is for ~pierre-php to click the 'upgrade' on that page.

Probably Launchpad should bulk-upgrade them; I'll see what we can do about that.

oh, and another solution is for a losa to upgrade this particular branch; I'll see if we can do that.

I think it's a bug in Launchpad that branches get in this state (or an operational issue, call it what you will).

It's not at all obvious to the affected user what they ought to do to get out of it. If they are supposed to ask the branch owner to upgrade the branch first then there is potentially several days delay while they wait and then a bit more delay if they ask a losa to do it instead. This also keeps generating user support questions.

I'm not going to work on this right now, but I think what we ought to do is find all branches in this state and upgrade them. bzr formats that can't understand 2a are quite obsolete at this point. We can possibly make a copy of them in their current semi-broken state just in case that is wanted.

Doing a bzr check on the branch results in the following:

We've tried clicking the upgrade button, as well as doing it manually.
When we go to browsse the branch we see:
"Something broke while generating the page. Please try again in a few minutes, and if the problem persists file a bug at and quote OOPS-ID OOPS-2056CBA418" from codebrowse.

We have a tarball of the original branch saved.

We have filed RT #47986 to upgrade all branches to 2a format. When that is complete, there will be no cross-format stacked branches, so this bug can be closed.
