-------------------------------------
Summary: MailImpl derivation truncation might make diagnostic
harder
Key: JAMES-4028
URL: https://issues.apache.org/jira/browse/JAMES-4028
Project: James Server
Issue Type: Improvement
Reporter: Benoit Tellier
I was investigating a forward loop ( :-( ) and to my unplaisure, because mail
names are limited to 86 characters,
This caused the lopped email name not to be prefixed by the name of the
original name:
{code:java}
Mail1713173708159-16b6f285-e237-405f-800f-6a54926825e6-!5984740
713173708159-16b6f285-e237-405f-800f-6a54926825e6-!5984740-!9588184-!2870433
285-e237-405f-800f-6a54926825e6-!5984740-!9588184-!2870433-!9660160-!4179738
-6a54926825e6-!5984740-!9588184-!2870433-!9660160-!4179738-!0418990-!8605805
{code}
Current rule:
- 4 char for 'Mail' prefix
- 15 char for current unix timestamp
- 1 char separator
- 38 char uuid
- up to 7 x 9 derivative suffix
Which means that truncation happens after 4 derivates.
By twikking slightly generation mechanisms we can get a more compact name that
wouldn't get truncated to fir the 86 char rule.
- 4 char for 'Mail' prefix
- 15 char for current unix timestamp - to be kept as some people might use it
as diagnostic information?
- 1 separator
- Generate a 20 char random alphanumeric name. Entropy should be similar with
the uuid
- Rework each derivative suffix to be 5 char - use `!` as a demiiter and not
`-!` and rely on alpha numeric for a more compact representation
That way truncation never happens, and I could filter easily by base email name
onto my favorite mailing system to see the whole history without headache.
