22:08 May 21, 2006 newsd fails with 'unknown command' when doing a search operation [Edit|Find|Search Messages] in Firefox. For instance, searching the Subject for the string "OSX": newsd[25668]: GOT: MODE READER newsd[25668]: GOT: GROUP rush.general newsd[25668]: GOT: XPAT SUBJECT 1- *[Oo][Ss][Xx]* ^^^^ The XPAT function [RFC-2980 2.9.0] needs to be implemeted.

10:36 Mar 29, 2009 STR #24 also covers this; making this the master as it came first: Implement the XPAT NNTP command, eg: XPAT header range|<message-id> pat [pat...] See these relevant sections for implementation: RFC# Section Command Description ---- ------- --------- ------------------------------------ 2980 2.9 XPAT Command newsreaders invoke to search 2980 3.3 WILDMAT Format of XPAT's 'pat' argument 1036 2.[12] (Headers) Format of XPAT's 'header' argument This can probably be implemented into the 1.x stream. At minimum, implement as a global search on the message text, stopping at the end of the headers, or go the extra step of having newsd create a single 'headers' cache file, so that searches on the headers can be done with as low impact on the server's cpu as possible. If the cache file approach is taken, make a simple newsd command line option that makes it easy to regenerate the cache files if corrupted, or when upgrading existing newsgroups. eg: newsd -recache newsgroup|* [newsgroup..] I highly advise making the cache files pure ascii, so that they can be easily inspected for corruption. Design of the file format should probably be optimized for XPAT's specific needs.
