Message120158
Following the first example of the documentation:
import nntplib
s = nntplib.NNTP('news.trigofacile.com')
resp, count, first, last, name = s.group('fr.comp.lang.python')
print('Group', name, 'has', count, 'articles, range', first, 'to', last)
resp, overviews = s.over((last - 9, last))
for id, over in overviews:
print(id, nntplib.decode_header(over['subject']))
s.quit()
An exception is raised:
"OVER/XOVER response doesn't include names of additional headers"
I believe the issue comes from the fact that the source code does not
handle the case described in Section 8.3.2 of RFC 3977:
For all fields, the value is processed by first removing all CRLF
pairs (that is, undoing any folding and removing the terminating
CRLF) and then replacing each TAB with a single space. If there is
no such header in the article, no such metadata item, or no header or
item stored in the database for that article, the corresponding field
MUST be empty.
Example of a successful retrieval of overview information for a range
of articles:
[C] GROUP misc.test
[S] 211 1234 3000234 3002322 misc.test
[C] OVER 3000234-3000240
[S] 224 Overview information follows
[S] 3000234|I am just a test article|"Demo User"
<nobody@example.com>|6 Oct 1998 04:38:40 -0500|
<45223423@example.com>|<45454@example.net>|1234|

Note the missing "References" and Xref headers in the second line,
the missing trailing fields in the first and last lines, and that
there are only results for those articles that still exist.
Also please note that nntplib should also work in case the database is not consistent. Some news servers might be broken and do not follow the MUST NOT...
The LIST OVERVIEW.FMT command SHOULD list all the fields for which
the database is consistent at that moment. It MAY omit such fields
(for example, if it is not known whether the database is consistent
or inconsistent). It MUST NOT include fields for which the database
is inconsistent or that are not stored in the database. Therefore,
if a header appears in the LIST OVERVIEW.FMT output but not in the
OVER output for a given article, that header does not appear in the
article (similarly for metadata items). |
