Alexander Barton : Make server reconnect time a little bit more random

This should make it even more unlikely that two servers deadlock each other when both are trying to connect to the other one at the same time, for example in test environments. --- src/ngircd/conf.c | 8 ++++++-- 1 file changed, 6 insertions(+), 2 deletions(-) diff --git a/src/ngircd/conf.c b/src/ngircd/conf.c index 6a7f633..8152512 100644 --- a/src/ngircd/conf.c +++ b/src/ngircd/conf.c @@ -481,8 +481,12 @@ Conf_UnsetServer( CONN_ID Idx ) * require the next attempt to be delayed. */ Conf_Server[i].lasttry = t - Conf_ConnectRetry + RECONNECT_DELAY; - } else - Conf_Server[i].lasttry = t; + } else { + /* "Short" connection, enforce "ConnectRetry" + * but randomize it a little bit: 15 seconds. */ + Conf_Server[i].lasttry = + t + rand() / (RAND_MAX / 15); + } } } }

Alexander Barton : Don' t accept connections for servers already beeing linked

And this could lead to all kind of weirdness (even crashes!) later on. So now such incoming connections are dropped. But this most probably prevents the two servers from linking until timing changes somehow (network latency?) because each server drops the incoming connection of the other one, so no connection survives in the end.

Module: ngircd.git Branch: master Commit: 58abd0777b0924e5cb8fa6c01b56305d9b175608 URL: http://ngircd.barton.de/cgi-bin/gitweb.cgi?p=ngircd.git&a=commit;h=58abd077… Author: DNS <dns(a)rbose.org> Date: Thu Oct 11 01:53:20 2012 +0200 Increased maximum number of possible user and channel modes Currntly ngIRCd supports 13 user and 15 channel modes, because there have been quite a few additions since our last release. But our data structures can only hold 15 user and -- even worse! -- only 9 channel modes! So enlarge the buffers to 20 bytes (actually 21 including NULL) to allow storing of all mode characters and to have some space left for more modes to come ...
