-TODO for Irssi SILC Client 1.0
-==============================
+TODO for 1.2 And Beyond
+=======================
- o Support to set arbitrary pulic key in CMODE.
+NOTE: Any item that doesn't have (***DONE) in it, isn't done yet. The
+(***TESTING NEEDED) means that the item has been done but not yet properly
+tested.
- o INVITE/BAN by public key file.
+NOTE: A TODO entry does not mean that it is ever going to be done. Some
+of the entries may be just ideas, good, bad or ugly. If you want to work
+on some of the TODO entries simply let us know about it by dropping a note
+to silc-devel mailing list or appear on 'silc' channel on SILCNet.
- o Signed message payload handling on UI
- o bugs parsing nicknames with @ in NICK_CHANGE
+lib/silccore
+============
- o Testing - See test plan:
- http://silcnet.org/docs/silc-client-1.0-test.pdf
- http://silcnet.org/docs/silc-client-1.0-test.ps
+ o SILC_PACKET_FLAG_ACK support. Implement ACK packet and packet payload
+ to silcpacket.c.
+ o All payload encoding routines should take SilcStack as argument.
-TODO for SILC Server 1.0
-========================
+ o Remove SilcCommandCb from silccommand.h. (***DONE)
+
+ o All payload test routines into lib/silccore/tests/.
+
+
+lib/silcclient, The Client Library
+==================================
+
+ o LIST command should take server name as argument, a server name whose
+ channels to list. This way it is possible to list channels from
+ any server in internet, eg. /LIST example.com.
+
+ o UDP SILC connection support to SILC server
+
+ o Giving WHOIS for nick that doesn't exist should remove any same
+ named entries from the client cache.
+
+ o peer-to-peer private messages
+
+ o Private message key request notification to application. See XXX in
+ client_prvmsg.c.
+
+ o in JOIN notify handle resolving that timedout. Currently the user is
+ never joined the channel if this happens. What to do if message is
+ received from user that hasn't been resolved/joined?
+
+ o Connection option that attemps to connect to remot host with various
+ different mechanisms: UDP 706, TCP 706, TCP 80, TCP 443, UDP 7706 and
+ TCP 7706. This is the so called hole punching mechanism.
+
+ o Message ACKing support.
- o 1.2 backup router support
+ o in /cmode and /cumode with +r, maybe the public key and private key
+ could be just some "string", which would then match to "string.pub" and
+ "string.prv".
- o Testing
+ o If the SILC Events (see below) are implemented, perhaps client library
+ should provide events so that application developer has a choice of
+ developing the SILC app with callbacks or with events.
+ o Ability to recover from rekey errors, at least try to.
-TODO/bugs In SILC Libraries
+ o Add the SilcStream (socket stream) from the SilcPacketStream and
+ SilcSocket from the socket stream to SilcClientConnection for easier
+ access to them for programmers. Currently these have to be digged up
+ from the packet stream. (***DONE)
+
+
+SFTP Library, lib/silcsftp/
===========================
- o WIN32 silc_net_create_connection_async does not work the same way
- than on Unix. Do it with threads on WIN32. The function works but
- is not actually async currently (Fix this to 0.9.x).
+ o Read prefetch (read-ahead, reading ahead of time). Maybe if this can
+ be done easily.
+
+
+lib/silcske/silcske.[ch]
+========================
+
+ o Ratelimit to UDP/IP transport for incoming packets.
+
+
+apps/silcd
+==========
+
+ o Deprecate the old server. Write interface for the new lib/silcserver
+ server library. The interface should work on Unix/Linux systems.
+
+ o Consider deprecating also the old config file format and use XML
+ istead. This should require SILC XML API implementation first.
+
+ o The configuration must support dynamic router and server connections.
+ The silcd must work without specifying any servers or routers to
+ connect to.
+
+ o The configuration must support specifying whether the server is
+ SILC Server or SILC Router. This should not be deduced from the
+ configuration as it was in < 1.2.
+
+ o The configuration must support specifying the ciphers and hmacs and
+ their order so that user can specify which algorithms take preference.
+
+
+lib/silcserver
+==============
+
+ o Rewrite the entire server. Deprecate apps/silcd as the main server
+ implementation and create lib/silcserver/. It is a platform
+ independent server library. The apps/silcd will merely provide a
+ a simple interface for the library.
+
+ o Write the SILC Server library extensively using SILC FSM.
+
+ o Server library must support multiple networks. This means that one
+ server must be able to create multiple connections that each reach
+ different SILC network. This means also that all cache's etc. must
+ be either connection-specific or network-specific.
+
+ o Library must support dynamic router and server connections. This means
+ that connections are create only when they are needed, like when someone
+ says JOIN foo@foo.bar.com or WHOIS foobar@silcnet.org.
+
+ o Library must support server-to-server connections even though protocol
+ prohibits that. The responder of the connection should automatically
+ act as a router. The two servers create an own, isolated, SILC network.
+ To be used specifically with dynamic connections.
+
+ o Library must support multiple threads and must be entirely thread safe.
+
+ o Library must have support for SERVICE command.
+
+ o Both UDP and TCP support for incoming connecetions. Maintaining long
+ term UDP sessions.
+
+ o The server must be able to run behind NAT device. This means that
+ Server ID must be based on public IP instead of private IP (See
+ also NAT detection protocol in SILC protocol specification).
+
+ o The following data must be in per-connection context: client id cache,
+ server id cache, channel id cache, all statistics must be
+ per-connection.
+
+ o The following data must be in per-thread context: command context
+ freelist/pool, pending commands, random number generator.
+
+ o Do inccoming packet processing in an own FSM thread in the
+ server-threads FSM. Same as in client library.
+
+ o Binding to other ports than 706 too. To allow easier traversing
+ through NATs and firewalls server should also bind to 80, 443 and 7706
+ by default (at least try to bind). Connections must work normally
+ even if they were established to some other port other than 706.
+
+ Connection option that attemps to connect to remot server with various
+ different mechanisms: UDP 706, TCP 706, TCP 80, TCP 443, UDP 7706 and
+ TCP 7706. This is the so called hole punching mechanism.
+
+ o Ability to recover from rekey errors, at least try to.
+
+ o Reference count all Silc*Entry structures.
+
+ o All channel names in any command (where appropriate) must be allowed to
+ be in format channel@server so that the server can be connected to do
+ the command for the channel. Change protocol if it doesn't allow it.
+
+ o All nicknames in any command (where appropriate) must be allowed to be
+ in format nick@server so that the server can be connected to do the
+ command for the nickname. Change protocol if it doesn't allow it.
+ Some issues that must be kept in mind from 1.0 and 1.1 silcd's:
-TODO in Toolkit Documentation
-=============================
+ o The server and router software MUST work out of the box. After
+ installation the server must not require any configuration to run the
+ most basic working configuration. No defining IP addresses, etc.
+ The server must work just by running it.
-Stuff that needs to be done in order to complete the Tooolkit Reference
-Manual (Do these to 0.9.x).
+ o The SERVER_SIGNOFF notify handing is not optimal, because it'll
+ cause sending of multiple SIGNOFF notify's instead of the one
+ SERVER_SIGNOFF notify that the server received. This should be
+ optimized so that the only SERVER_SIGNOFF is sent and not
+ SIGNOFF of notify at all (using SIGNOFF takes the idea about
+ SERVER_SIGNOFF away entirely).
- o Document the "notify" and "command_reply" client operations variable
- argument lists for all possible notify types and command replys.
+ o Another SERVER_SIGNOFF opt/bugfix: Currently the signoff is
+ sent to a client if it is on same channel as the client that
+ signoffed. However, the entire SERVER_SIGNOFF list is sent to
+ the client, ie. it may receive clients that was not on the
+ same channel. This is actually against the specs. It must be
+ done per channel. It shouldn't receive the whole list just
+ because one client happened to be on same channel.
- o Write "Programming with Toolkit" document, describing how to build
- Toolkit, how the build system works, where is everything, how
- new (external) projects can be glued into Toolkit (use irssi as an
- example), and how external projects can use Toolkit without gluing into
- it (how to link etc), debugging, architecture, types, etc.
+ o If client's public key is saved in the server (and doing public key
+ authentication) then the hostname and the username information could
+ be taken from the public key. Should be a configuration option!
- o Write "Platform Implementations" document to describe what platforms
- Toolkit support, what has been implemented, what has not been, what
- works differently etc.
+ o Add a timeout to handling incoming JOIN commands. It should be
+ enforced that JOIN command is executed only once in a second or two
+ seconds. Now it is possible to accept n incoming JOIN commands
+ and process them without any timeouts. THis must be employed because
+ each JOIN command will create and distribute the new channel key
+ to everybody on the channel.
- o Searching of predefined keywords, exact and partial matches (would be
- nice).
+ o Related to above. If multiple JOINs are received in sequence perhaps
+ new key should be created only once, if the JOINs are handeled at the same
+ time. Now we create multiple keys and never end up using them because
+ many JOINs are processed at the same time in sequence. Only the last
+ key ends up being used.
