Sebb commented on COMDEV-161:
-----------------------------
Furthermore, the RE matches anywhere in the string, not just at the start of a
line.
> mailglomper.py may count a message multiple times

> The mailglomper.py script counts messages by matching /Date: (.*)/.
> It is looking to match header lines of the form:
> Date: Thu, 01 May 2008 05:06:51 +0000
> However such lines are not guaranteed to be unique within a message.
> In particular SVN commit messages have a "Date:" line which matches, and the
> parsed timestamp will be much the same as the header date. For example:
> Author: cml
> Date: Wed Sep 16 19:06:03 2015
> New Revision: 1703436
> The mailbox format currently used by the ASF guarantees that each message is
> prefixed with a line in the format:
> From u...@example.com Thu May 01 05:10:32 2008
> [Lines in the message body starting "From " are prefixed as ">From "; the
> prefix is removed when messages are extracted]
> Only lines starting "From " are guaranteed not to occur in message bodies.
> The problem is trivial to fix, but it will change the generated statistics,
> particularly for mailboxes that receive SVN commit messages (Git commits use
> a different prefix for the timestamp). SVN mails will generally be counted
> twice.
