TODO/bugs in Irssi SILC client
==============================
- o Fix the silc_channels_join to parse the command like, with fe.
- silc_parse_command_line, because currently it ignores all options,
- including passphrase which makes autojoin impossible to +a channels.
- Other important options are ignored too.
+ o Does not show ops and normal users on JOIN correctly, perhaps some
+ theme issue (Fix this to 0.8.x).
- o Add local command to switch the channel's private key when channel has
- several private keys. Currently sending channel messages with many
- keys is not possible because changing the key is not possible by the
- user.
-
- o /cumode for unknown nick does not give any error message.
+ o /cumode for unknown nick does not give any error message (Fix this to
+ 1.0).
TODO/bugs In SILC Client Library
o The PRIVATE_MESSAGE_KEY packet is not handled (it is implemented
though). This should be added and perhaps new client operation
should be added to notify application that it was received and
- set the key only if application wishes to set (accept the key) it.
+ set the key only if application wishes to set (accept the key) it
+ (Do this to 1.0).
o Additions to do after protocol version 1.1:
TODO/bugs In SILC Server
========================
- o Configuration file additions:
+ o Configuration file additions (Do this to 0.8.x):
o Add incoming connection frequency, incoming connection frequency
for single IP address, key exchange frequency, key exchange
frequency for single IP. Add also frequency base.
- o Add hashed passwords to config file.
-
- o Add rehashing support.
-
o If server send CUMODE_CHANGE notify (like setting founder) to router
and router does not have founder on channel (founder is left or there's
no founder on channel at all), the router will accept the server's
- founder mode change, even though it perhaps should not do that.
+ founder mode change, even though it perhaps should not do that (Fix
+ this to 0.9).
o The router should check for validity of received notify packets from
- servers (after all buggy servers may send notify that is actually
- something that should have not been sent).
+ routers (fix this to 0.9). Following NOTIFYs needs to be verified:
+
+ o JOIN (check that joining is allowed)
+ o SIGNOFF (maybe should check that notifier owns the client)
+ o KILLED (check that killling is allowed (Protocol TODO #13))
+
+ o Backup router related issues (Fix this to 1.0):
+
+ o Channel user mode changes are notified unnecessarely when
+ switching to backup router on router crash.
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 Channel user mode changes are notified unnecessarely when
- switching to backup router on router crash.
+ to everybody on the channel (Fix this to 1.0).
o Lots of statistics updating is missing around the server.
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.
-
- o Rewrite the lib/silcsim/silcsim.h. The SilcSimContext should be
- private and silc_sim_alloc should take necessary arguments.
-
- o SILC RNG does not implement random seed files, and they should be
- implemented.

-TODO After 1.0
-==============
-
-A rough list of stuff that is going to be done to SILC after 1.0 or at
-least could be done.
-
- o Implement the defined SilcDH API. The definition is in
- lib/silccrypt/silcdh.h.
-
- o X.509 certificate support. SILC protocol supports certificates and
- it would be great to have support for them. This is a big task as
- support has to be made for ASN.1 as well. I've looked into OpenSSL
- package as it has X.509 certificate support (and ASN.1 as well).
- The code does not look very good to my eye but it has some potentials.
- This should be looked at more closely.
-
- Naturally own SILC Certificate API has to be defined regardles what
- the actual X.509 library is (OpenSSL X.509 or something else). Other
- choice is to write own X.509 library but I'm not going to do it -
- I can help to migrate the OpenSSL X.509 into SILC and I can help if
- someone would like to write the X.509 library - but I'm not going
- to start writing one myself. Anyhow, the OpenSSL X.509 lib should
- be checked.
-
- Other package that should be checked is the NSS's X509 library,
- which I like more over OpenSSL package.
-
- o SSH2 public keys support, allowing the use of SSH2 public keys in
- SILC.
-
- o OpenPGP certificate support, allowing the use of PGP public keys
- in SILC.
-
- o Compression routines are missing. The protocol supports packet
- compression thus it must be implemented. SILC Zip API must be
- defined.
-
- o Rewrite the lib/silcutil/silcprotocol.[ch] not to have [un]register
- functions, but to make it context based all the way. The alloc should
- take as argument the protocol type and its callback (not only
- final callback). It is not good that we have now global list of
- registered protocols.
-
- o Optimizations in Libraries
-
- o There is currently three (3) allocations per packet in the
- silc_packet_receive_process, which is used to process and
- dispatch all packets in the packet queue to the parser callback
- function. First allocation is for parse_ctx, second for the
- SilcPacketContext, and third for packet->buffer where the actual
- data is saved.
-
- The parse_ctx allocation can be removed by adding it as a
- structure to the SilcPacketContext. When the SilcPacketContext
- is allocated there is space for the parse context already.
-
- The silc_packet_context_alloc could have a free list of
- packet contexts. If free packet context is found from the list
- it is returned instead of allocating a new one. The library
- could at first allocate them and save them to the free list
- until enough contexts for smooth processing exists in the list.
- This would remove a big allocation since the structure is
- quite big, and even bigger if it would include the parse_ctx.
-
- The packet->buffer can be optimized too if the SilcBuffer
- interface would support free lists as well. Maybe such could
- be done in the same way as for SilcPacketContext. The
- silc_buffer_alloc would check free list before actually
- allocating new memory. Since the packets in the SILC protocol
- usually are about the same size (due to padding) it would be
- easy to find suitable size buffer from the free list very
- quickly.
-
- These naturally cause the overal memory consumption to grow
- but would take away many allocations that can be done several
- times in a second.
-
- o Move the actual file descriptor task callback (the callback that
- handles the incoming data, outgoing data etc, that is implemnted
- in server and client separately (silc_server_packet_process and
- silc_client_packet_proces)) to the low level socket connection
- handling routines, and create an interface where the application
- can register a callbacks for incoming data, outoing data and EOF
- receiving, which the library will call when necessary. This way
- we can move the data handling in one place.
-
- o Add silc_id_str2id to accept the destination buffer as argument
- and thus not require any memory allocation. Same will happen
- with silc_id_payload_* functions.
-
- o Remove the `truelen' field from SilcBuffer as it is entirely
- redundant since we can get the true length of the buffer by
- doing buffer->end - buffer->header. Add SILC_BUFFER_TRUELEN
- macro instead. Consider also removing `len' field too since
- it effectively is buffer->tail - buffer->data, and adding
- SILC_BUFFER_LEN macro can do the same. These would save
- totally 8 bytes of memory per buffer.
-
- Add also perhaps function silc_buffer_alloc_size that would
- effectively do:
-
- return silc_buffer_pull_tail(silc_buffer_alloc(size),
- size);
-
- to not require the user to give the pull_tail anymore.
-
- o Optimizations in Server
-
- o Remove the big switch statement from the function
- silc_server_packet_parse_type and replace it with predefined
- table of function pointers where each of the slot in table
- represents the packet type value.
-
- Same could be done with notify packets which has big switch
- statement too. Same kind of table of notify callbacks could be
- done as well.
-
- o The parser callback in the server will add a timeout task for
- all packets. It will require registering and allocating a
- new task to the SilcSchedule. Maybe, at least, for server
- and router packets the parser would be called immediately
- instead of adding it to the scheduler with 0 timeout. It
- should be analyzed too how slow the task registering process
- actually is, and find out ways to optimize it.
-
- 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 Add SilcAsyncOperation to utility library. Any function that takes
- callback as an argument must return SilcAsyncOperation.
-
- o Add DSS support.
-
- o Cipher optimizations (asm, that this) at least for i386 would be nice.
-
- o Add builtin SOCKS and HTTP Proxy support, well the SOCKS at least.
- SILC currently supports SOCKS4 and SOCKS5 but it needs to be compiled
- in separately.
+ 15. The LEAVE command reply should return the Channel ID of the channel
+ that was parted.
