They should be - configurable and the Irssi SILC client should be able to set them - with for example /set key_exchange_timeout etc. The silc_client_alloc - should take a Params structure or something as argument. - - o silc_client_close_connection leaks memory. Read the XXX from code. - - o Some of the ops->say's should be removed and moved to the application - from the library. Go through these. - - o The client library must manage somehow when receiving client that has - same nickname, same server, same username but different Client ID than - what we have in the cache. It is now assumed that they are different - client but it might not be. It should at least number the clients - using the client->num so that they can be accessed from the user - interface separately or it could just remove the old client unless - it is on some channels. - - o Add client library parameters or options that handle what kind of - messages the library should print out (using `say' client operation, - for example) and what is left for the application to print. The - appliation could for example set that it handles all command printing - but all error printing should be handled by the library, etc... - This is not a showstopper. + o When changing own nickname and there exists a same nickname the library + can give the client now nickname in format nick@host. This is new + behaviour and maybe should be removed. The changer should always + get the one it wants and not have the formatted nickname. TODO/bugs In SILC Server ======================== - o Normal server seemed not to distribute the SERVER_SIGNOFF properly - when its router disconnected. - - o Router seemed not to force the channel mode change if the normal - server announced different modes than what the router had. For example - if router crashed and then reconnected the server had different - modes on the channel. + o If auto-reconnecting to router and EOF is received during the + connecting phase the server will not try to auto-reconnect anymore + after that. Fix to auto-reconnect. - o When server quits and all clients of that server are removed from all - channels the channel keys are re-generated for all clients. This is - a bug and should be done only once per channel after all clients of - the server has been removed. + o Backup router related issues - o Incomplete IPv6 support: + o Channel user mode changes are notified unnecessarely when + switching to backup router on router crash. - o silc_server_get_users_on_channel does not support IPv6 based - Client ID's. - o silc_server_route_get and the route code in general supports - only IPv4. - o silcd/serverid.c and its routines supports only IPv4. - - o DNS/IP lookup blocks the server. This must be fixed. Check the - resolver stuff (resolver(3), resolver(5)). Either we have to do the - own resolver stuff (through scheduler, if possible without writing - too much own stuff) or use threads. - - o The backup router support described in the protocol specification - should be done at some point. + 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 New configuration file format must be added.

Additional specification (or appendix) should + be done to define the payload and the parameters.

The second field is used only + if there is list of errors. If normal status, or normal (single) + error status the second field is set to zero, and must be ignored. + Hence, the status works same way as now except for list of errors. + To be included in protocol version 1.1. + + o Define that WHOIS and IDENTIFY commands must send list of errors + if multiple Client ID (or Channel ID and Server ID for IDENTIFY) was + requested and was not found.
