Correctly detect when SSL subsystem must be initialized
This patch introduces the new function Conf_SSLInUse() to check when the
current server configuration requires the SSL subsystem to be initialized
and accounts incoming as well as outgoing connections -- so this fixes
commit bb20aeb9 ("Initialize SSL when needed only, and disable SSL on
errors") which only handled the inbound case ...
* bug145-ProvideHelp:
Use "${docdir}/Commands.txt" as help text file
Add a note that "help file" is updated on startup and REHASH only
Add doc/Commands.txt which should document all commands
Implement Help() function parsing and returning the help text
Document "HelpFile" in sample-ngircd.conf and ngircd.conf.5
Implement new configuration option "HelpFile"
IRC_HELP(): Code cleanup
Refactor Read_Motd() into Read_TextFile()
Implement Help() function parsing and returning the help text
This function parses the already read in help text and sends the requested
portions to the user. Parsing is done as following when a user user
issues a "HELP <cmd>" command:
1. Search the file for a line "- <cmd>",
2. Output all subsequent lines that start with a TAB (ASCII 9) character
to the client using NOTICE commands, treat lines containing a single "."
after the TAB as empty lines.
3. Break at the first line not starting with a TAB character.
This format allows to have information to each command stored in this file
which will not be sent to an IRC user requesting help which enables us to
have additional annotations stored here which further describe the origin,
implementation details, or limits of the specific command.
A special "Intro" block is returned to the user when the HELP command is
used without a command name.

Mode setting: only check channel user modes when on channel
Only check the channel user modes of the initiator if he is joined to
this channel and not an IRC operator enforcing modes (which requires

Makefiles: Correctly quote sed expressions
Now the Makefiles support spaces in "$sysconfdir", which isn't uncommon
for Cygwin for example, when $HOME contains whitespaces ("/home/User Name")
and ngIRCd is installed into the user home ("./configure --prefix=$HOME").
Now ngIRCd uses two fields internally, one to store the "real" hostname
and one to save the "cloaked" hostname. And both fields can be set
independently using the "METADATA host" and "METADATA cloakhost" commands.
This allows "foreign servers" (aka "IRC services") to alter the real and
cloaked hostnames of clients without problems, even when the user itself
issues additional "MODE +x" and "MODE -x" commands.

Add new IRC+ server flag "X": "XOP modes supported"
This flag indicates, that the server supports the enhanced "xop channel
user modes", like channel owner, admin, and halfop. This information is
used to make sure that no unsupported CHANINFO commands are sent to
servers not supporting such mode prefixes, for example.
Starting with Anope 1.9.8, the ngIRCd protocol module is included in the
Anope distribution, so there's no longer any need to support our own (but
now heavily outdated!) patches. Therefore remove them.

doc/Services.txt: Update documentation for Anope 1.9.8
Starting with Anope 1.9.8, the ngIRCd protocol module is rewritten from
scratch by "DukePyrolator" and included in the Anope distribution. So no
patching is required any more, yeah!
Drawback: Anope 1.9.8 is in development and not yet released ...
Use "METADATA host" commands to let servers supporting this command
know which (possibly cloaked) hostname is in effect for a specific
client. This prevents "double cloaking" of hostnames and even cloaked
hostnames are in sync on all servers supporting "METADATA" now.
Don't cloak already cloaked hostname when using METADATA
A client for which a METADATA command has been received from one of
its peers got the client flag "M" set. So it's safe to assume that
such a client gets "METADATA host" commands for its cloaked hostname
and the server must not cloak the hostname on its own, even when the
client mode "+x" is set.
Implement METADATA command to update client metadata
The METADATA command can be used by other servers to update "metadata"
of registered clients, like the client info text ("real name"), user
name, and hostname:
:<prefix> METADATA <target> <key> :<value>
It is distributed in the network, unknown <key> names are silently ignored
and passed on, too. This allows for further extensions.

PredefChannelsOnly: Fix message for non pre-defined channels
If PredefChannelsOnly is enabled, and if someone tries to create
a channel which does not exist, then the error message is a 474.
The 474 Error message changed recently and does not match anymore:
'Cannot join channel (+b) -- You are banned'.
Changed the error message to numeric 403 'No such channel'.
Now NICK commands are always generated using the prefix of the target
user, even when the nickname change has been initiated by some other
(pseudo) server or using the SVSNICK command. In this case, the prefix
of the initiator has been used, but this isn't compatible with clients
(at least weechat and irssi don't handle such NICK commands correctly).
Implement SVSNICK command to change remote nicknames
The SVSNICK command allows other servers (and services on
"pseudo-servers") to forcefully change nicknames of remote users.
Syntax: ":<from> SVSNICK <oldnick> <newnick>"
The SVSNICK command itself doesn't change the nickname, but it becomes
forwarded to the server to which the user is connected to. And then this
server initiates the real nickname changing using regular NICK commands.
This allows to still run networks with old servers not supporting the
SVSNICK command, because SVSNICK commands for nicknames on such servers
are silently ignored and don't cause a desync of the network.

Make server reconnect time a little bit more random
Add randomly up to 15 seconds to the reconnect delay for outgoing server
links when the connection has been "short" and therefore the "ConnectRetry"
delay is being enforced.
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.
Alexander Barton [Sun, 28 Oct 2012 18:48:24 +0000 (19:48 +0100)]
Don't accept connections for servers already beeing linked
If two servers try to link each other, there was a time frame that
could result in one connection overwriting the other, e. g. the incoming
connection overwriting the status of the outgoing one. 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.
But this has to be addressed by an other patch ...
