set retention UE

Post by bluecupra »

Today i registered UE. I used NP for quite an long time and the first impressions are very good. It's fast and my system has an much less "stress" then with NP.

I have one question concerning setting the retention. Could anyone explain what all the options are?

default
natural
7 (days)
36 h
10-20
1h - 1h
12h - 3d - 12h
48h-72h
7-
12h-
10 jan
25mar03
1 dec - 15 dec
10 apr04 - 15apr04
12aug-
-14 sep02

What is the difference between 7 and 7-? and what are all the different time settings?

Thanks,

Jeffrey

in ue i made retention hourly but otherwise is close to newspro logic.

7 is the same as 0-7 or ...-7 which means messages not older than 7 days.

7... or 7-... means messages older than 7 days

25mar03 means only headers from this date

since servers don't have effective commands to work with retentions ue or newspro still need to download more headers to find the headers within the retention range, i think there is some info about in UE.txt. still ue is faster when you have most common retention form since it interrupts header connections while determining range and newspro always scans to the end.

natural means all server headers (but see UE.txt since for most newsgroup destination types if you use natural and don't define last headers the newsgroup will grow indefinitely).

default means use the retention settings from the topmost entry.

usually one uses the first form of retention like "14", messages within last x days, the most trivial when most newsgroups have default retention and in the default entry you put x days.

hourly delay is for when you have expensive server and e.g. isp server and the expensive server gets headers earlier you can "delay" downloading headers (still at price of some header bandwidth) so bodies will be always downloaded from the cheap server even if they arrive there later (in theory, just it was asked with newspro so when i reimplemented it in ue i use hourly basis, to rewrite it in newspro would be quite messy).
