From b2688f6cdf45c70985754001edcc2b1916f5bcb4 Mon Sep 17 00:00:00 2001 From: danieldg Date: Mon, 2 Mar 2009 23:38:04 +0000 Subject: [PATCH] Revert "Don't apply channel modes received in an non-burst, non-creation FJOIN, because they could be out of date" This keeps the protocol closer to TS6 behavior. The mode sync in the FJOIN is used to resync channel modes after a desync caused by modes crossing on the wire. In the future, an alternate join command will be used to prevent MODExJOIN desync without rejecting modes from an FJOIN. This reverts commit 4820e6bb9578e53ea1553070108599349d0ffbcb. git-svn-id: http://svn.inspircd.org/repository/trunk/inspircd@11163 e03df62e-2008-0410-955e-edbf42e46eb7 --- src/modules/m_spanningtree/fjoin.cpp | 24 +++++------------------- 1 file changed, 5 insertions(+), 19 deletions(-) diff --git a/src/modules/m_spanningtree/fjoin.cpp b/src/modules/m_spanningtree/fjoin.cpp index e7ce0ac54..55c72c474 100644 --- a/src/modules/m_spanningtree/fjoin.cpp +++ b/src/modules/m_spanningtree/fjoin.cpp @@ -58,8 +58,7 @@ bool TreeSocket::ForceJoin(const std::string &source, std::deque &p std::string channel = params[0]; /* Channel name, as a string */ time_t TS = atoi(params[1].c_str()); /* Timestamp given to us for remote side */ irc::tokenstream users((params.size() > 3) ? params[params.size() - 1] : ""); /* users from the user list */ - bool apply_other_sides_umodes = true; /* True if we are accepting the other side's user umodes */ - bool apply_other_sides_cmodes = true; /* True if we are accepting the other side's channel modes */ + bool apply_other_sides_modes = true; /* True if we are accepting the other side's modes */ Channel* chan = this->ServerInstance->FindChan(channel); /* The channel we're sending joins to */ bool created = !chan; /* True if the channel doesnt exist here yet */ std::string item; /* One item in the list of nicks */ @@ -91,8 +90,7 @@ bool TreeSocket::ForceJoin(const std::string &source, std::deque &p if (ourTS < TS) { ServerInstance->SNO->WriteToSnoMask('d', "NOT Applying modes from other side"); - apply_other_sides_umodes = false; - apply_other_sides_cmodes = false; + apply_other_sides_modes = false; } else if (ourTS > TS) { @@ -106,23 +104,11 @@ bool TreeSocket::ForceJoin(const std::string &source, std::deque &p param_list.push_back(channel); this->RemoveStatus(ServerInstance->Config->GetSID(), param_list); } - else - { - /* Timestamp equal.
