From: Florian Westphal Date: Mon, 11 Feb 2008 11:06:31 +0000 (+0000) Subject: Make IRC_WHO also search username/servername/hostname. X-Git-Tag: rel-0-12-0-pre1~40 X-Git-Url: https://arthur.barton.de/cgi-bin/gitweb.cgi?p=ngircd-alex.git;a=commitdiff_plain;h=4d152b771e17c23823af995f86912d1550f4c244;hp=c634303765c20083c8f554f4d4084526d3e58fef Make IRC_WHO also search username/servername/hostname. Dana Dahlstrom reported that IRC_WHO did not follow RFC 2812, Section 3.6.1. Specifically: - IRC_WHO did not send "G" flag instead if "H" if client was away - did not search username/servername/hostname etc. if argument was not a channel. Fix all of the above and tidy things up a bit. Also add IRC_WHO test script contributed by Dana. --- diff --git a/ChangeLog b/ChangeLog index c18df41d..af9d14ca 100644 --- a/ChangeLog +++ b/ChangeLog @@ -11,7 +11,10 @@ ngIRCd HEAD - + - IRC_WHO now supports search patterns and will test this + against user nickname/servername/hostname, etc. as required by + RFC 2812, Section 3.6.1.
