Subject [jira] [Resolved] (INFRA-12020) Re-index lists.apache.org database to fix hashing bug
Date Fri, 03 Jun 2016 06:35:59 GMT

]

Daniel Gruno resolved INFRA-12020.
----------------------------------
    Resolution: Not A Problem
      Assignee: Daniel Gruno

shortlinks have been disabled, so this shouldn't be an issue.
a re-index would require 2-3 days of downtime, and we're not likely to ask for that, given
the current impact (or lack thereof) of this issue :)

> The original Pony Mail code had a bug which means that distinct mails can get the same
short hash if they have the same content, even if they are sent at different times to different
lists.
> This has the affect that the Permalink for message A can point to message B which may
be a message sent to a completely different list.
> According to the bug report I filed, to fix this requires a re-index [1]
> I have no idea how many mail messages this affects. I found the example by accident,
and have not tried to find more.
