I have added release URL patterns to all the series for all the projects in https://launchpad.net/sucrose, except the series called master. I think I added them all, I didn't do it in one continuous stretch. However, there is no UI indication that a release file glob has been set.
I checked the following day, and releases were imported for https://launchpad.net/sugar and https://launchpad.net/sugar-toolkit, but not the others in sucrose.
I got impatient with https://launchpad.net/sugar-base and manually added some releases. Did that block the automatic process of adding more? Perhaps I forgot to add the URL on the https://launchpad.net/sugar-base/sugar-0.79 series.
Certainly https://launchpad.net/sugar-artwork, https://launchpad.net/sugar-datastore and https://launchpad.net/sugar-presence-service have had no releases imported, and I cannot tell in the UI whether the URL was set, and what it was set to.
Hmm, I've gone back and checked the series that weren't populated, and I see that I can tell if I entered a URL in the release URL glob if I go to +edit - and the series that didn't have anything imported didn't have URLs.
Perhaps I didn't add the URLs for every series that I thought I had.
Nevertheless it would be great to show something about the URL being present on the series page - "releases automatically imported from $URL"...
