Support Dropbox-backed update sites better

At the moment, Dropbox does not support HTTP HEAD requests. As a consequence, our updater fails to obtain a timestamp and will never notify the user about updates on Dropbox-backed update sites.

What we need to do is detect that the HEAD request failed because it is unsupported and either write a TIMESTAMP file to the same update site or download the db.xml.gz file and inspect its contents to find the newest timestamp it contains (although the latter is fragile, e.g. when a file has been made obsolete).

  • Status changed from new to closed
  • Resolution set to fixed

DropBox made it harder for us by leaking information about the implementation details through the URLs. So while we added workarounds (d7d1629afd89aba53a74bdf72bcb8db5b16acf47 and later commits), using DropBox for update sites is seriously discouraged.

We have personal update sites at now.
