[jira] [Commented] (INFRA-12024) Permalink permanence

["Daniel Gruno (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/INFRA-12024?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15311950#comment-15311950 ] 

Daniel Gruno commented on INFRA-12024:
--------------------------------------

The shortlink issue has been addressed upstream.
As for "what happens if/when something new comes along", the document IDs can and would be exported along with the emails, so that should not be an issue.
Upgrading Pony Mail has no effect on older emails unless you re-index with a brand new algorithm (but why would you do that?)
I don't see any issue with "one cannot see which mailing list it is from". You can read the email and see which list it's on.
What we could do is simply have PonEE disable the short link feature if you are that concerned with this. The links would then be a full Message-ID.

> A permalink to a mail message should always be able to find the same mail.
> This is achieved for the existing mail archives by using the message-id.
> However the Pony Mail solution (as installed) uses a shorter hash generated from some of the mail contents.
> As a result, message links in future will be of two forms:
> http://mail-archives.apache.org/mod_mbox/httpd-dev/201606.mbox/%3CCACsi252b-KUB-HtPQTe7Ti%2Bxrek2XK%2B%3DuKvfcO9diCN0Dg1kKQ%40mail.gmail.com%3E
> and
> https://lists.apache.org/thread.html/Zfp0souj6y08k06
> The latter link is obviously much shorter, but has the disadvantage that it cannot be compared with existing links. Also one cannot see which mailing list it is from.
> Futhermore, the hashes are not stored in the mbox file, so it's not possible to search for the message in offline copies of the mail. AFAICT the hash only works with the correct version of the PonyMail software.
> I think the same permalink style must be retained for any mail archive system that is used by the ASF.
> What happens if (when) the mail archive software is changed again?
> Will there be 3 different permalink styles?
> I think this needs to be addressed urgently, before too many new style permalinks are published.
