Hello, all
There seems to be bug in Sylpheed's NNTP implementation.
When entering any "empty" newsgroup the following error
occurs:
[21:22:32] NNTP> GROUP fido7.zx.spectrum
[21:22:32] NNTP< 211 0 1240 1239 fido7.zx.spectrum
[21:22:32] invalid article range: 1240 - 1239
This article range is in fact valid and indicates an
empty newsgroup:
,----[ https://tools.ietf.org/html/rfc3977#section-6.1.1 ]
| If the group is empty, one of the following three sit-
| uations will occur. Clients MUST accept all three
| cases; servers MUST NOT represent an empty group in
| any other way.
|
| -- The high water mark will be one less than the low
| water mark, and the estimated article count will
| be zero. Servers SHOULD use this method to show
| an empty group. This is the only time that the
| high water mark can be less than the low water
| mark.
