overview.ctl − configuration file for unified overview
The file <pathetc in inn.conf> is required if the new storage API is used on machines running nnrpd(8). Optional on feed-only machines. If the file does not exist or is empty, no overview information will be written by innd(8).
The traditional overview database was written by an external program overchan(8), but with the unified overview, this is now done by innd(8). This is because the overview offset is written into a token, which is stored as the 3rd field of each history(5) entry. Overchan(5) is still needed to store the overview index and will require an entry in the newsfeeds(5) file. If the overview index is not created, the articles will not be available through nnrpd(8).
Overview entries are now expired with the normal expire(8) program and the overview index is expired with expireindex(8)
The file consists of a series of lines; blank lines and lines beginning with a number sign (’’#’’) are ignored. The order of lines in this file is important.
Each line is formatted as:
index_number:wildmat
The ’’index_number’’ is a number >= 0 and <255 and ’’wildmat’’ refers to a newsgroup pattern that will be parsed with wildmat(3). Matching newsgroup is against newsgroup name in ’’Xref’’ header, not ’’Newsgroups’’ header. ’’!’’ and ’’@’’ are allowed at the start of the wildmat and refer to pattern exclusions. See newsfeeds(5) for a description of their use. The ’’wildmat’’ is matched in order. There is no default ’’wildmat’’ pattern, so specified ’’wildmat’’ is only used for matching.
If a newsgroup matches wildmat pattern, overview data is stored in <pathoverview in inn.conf>/index_number/overview. Note that the file is interpreted in order and first match line is used to store overview data.
If a newsgroup does not match any wildmat pattern in any line, no overview data is stored for it and no articles can be retrieved from it for reading.
If the file is changed, it can be reloaded into INN using ’’ctlinnd reload overview.ctl reason’’ (see ctlinnd(8)).
