-General
-=======
-
- o Create apps/tutorial containing various Toolkit API tutorials.
-
- o The Toolkit split. The Toolkit is to be splitted in parts. How many
- parts and what the parts are isn't decided yet. Each part is a separate
- software package. Current thinking is of the following:
-
- SILC Toolkit SILC protocol, client and server library
- SILC Runtime Toolkit runtime library
- SILC Crypto Toolkit crypto, asn1, math, skr, pgp, etc.
-
- The rationale for this is of course that other than SILC projects
- might like to use the various libraries SILC Toolkit provides, but
- naturally they don't want the bloat of SILC protocol related stuff.
-
- The Runtime library in SILC Toolkit is a general purpose runtime library,
- like Glib and APR are. The runtime library is to be developed further
- to provide alternative to Glib and APR.
-
- The Crypto library in SILC Toolkit is a general purpose crypto library
- providing pretty nice APIs compared to many other crypto libraries,
- especially OpenSSL. The Crypto library is to be developed further
- to include support for OpenPGP, X.509 and SSH2.
-
-
-lib/silccore
-============
-
- 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.
-
- o All payload test routines into lib/silccore/tests/.
-
-
-lib/silcclient, The Client Library
-==================================
-
- 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 Message ACKing 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".
-
-
-Runtime library, lib/silcutil/
-==============================
-
- o Fix universal time decoding (doesn't accept all formats) in silctime.c.
-
- o Add functions to manipulate environment variables.
-
- SilcBool silc_setenv(const char *variable, const char *value);
- const char *silc_getenv(const char *variable);
- SilcBool silc_clearenv(const char *variable);
-
- o Add functions to loading shared/dynamic object symbols (replaces the
- SIM library (lib/silcsim) and introduces generic library). Add this
- to lib/silcutil/silcdll.[ch].
-
- SilcDll silc_dll_load(const char *object_path, SilcDllFlags flags);
- void silc_dll_close(SilcDll dll);
- void *silc_dll_getsym(SilcDll dll, const char *symbol);
- const char *silc_dll_error(SilcDll dll);
-
- o Add directory opening/traversing functions
-
- o silc_getopt routines
-
- o silc_hash_table_replace -> silc_hash_table_set. Retain support for
- silc_hash_table_replace as macro.
-
- o The SILC Event signals. Asynchronous events that can be created,
- connected to and signalled. Either own event routines or glued into
- SilcSchedule:
-
- SilcTask silc_schedule_task_add_event(SilcSchedule schedule,
- const char *event, ...);
- SilcBool silc_schedule_event_connect(SilcSchedule schedule,
- const char *event,
- SilcTaskCallback event_callback,
- void *context);
- SilcBool silc_schedule_event_signal(SilcSchedule schedule,
- const char *event, ...);
-
- Example:
- silc_schedule_task_add_event(schedule, "connected",
- SILC_PARAM_UI32_INT,
- SILC_PARAM_BUFFER,
- SILC_PARAM_END);
- silc_schedule_event_connect(schedule, "connected", connected_cb, ctx);
- silc_schedule_event_signal(schedule, "connected", integer, buf,
- SILC_PARAM_END);
- SILC_TASK_CALLBACK(connected_cb)
- {
- FooCtx ctx = context;
- va_list args;
- SilcUInt32 integer;
- SilcBuffer buf;
-
- va_start(args, context);
- integer = va_arg(args, SilcUInt32);
- buf = va_arg(args, SilcBuffer);
- va_end(args);
- ...
- }
-
- Problems: Events would be SilcSchedule specific, and would not work on
- multi-thread/multi-scheduler system. The events should be copyable
- between schedulers.
-
- o If the event signals are added, the SILC_PARAM_* stuff needs to be
- moved from silcbuffmt.h to silctypes.h or something similar.
-
- o In case the SILC Events are done we shall create a new concept of
- parent and child SilcSchedule's. When new SilcSchedule is created a
- parent can be associated to it. This association could be done either
- directly by the parent or by any other children. This way the signals
- would in effect be global and would reach all children schedulers.
-
- This relationship would be associative only. The schedulers are still
- independent and run independently from each other. All schedulers
- would be linked and could be accessed from any of the schedulers.
- It should be possible to retrieve the parent and enumate all children
- from any of the schedulers.
-
- SilcSchedule silc_schedule_init(int max_tasks, void *app_context,
- SilcSchedule parent);
- SilcSchedule silc_schedule_get_parent(SilcSchedule schedule);
-
- o Structured log messages to Log API. Allows machine readable log
- messages. Would allow sending of any kind of data in a log message.
-
- o Base64 to an own API
-
- o Timer API
-
- 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.
-
- o silc_stringprep to non-allocating version.
-
- o SilcStack aware SilcHashTable.
-
- o SilcStack aware SilcDList.
-
- o Thread pool API. Add this to lib/silcutil/silcthread.[ch].
-
- typedef void (*SilcThreadPoolFunc)(SilcSchedule schedule,
- void *context);
-
- /* Allocate thread pool with at least `min_threads' and at most
- `max_threads' many threads. If `stack' is non-NULL all memory
- is allocated from the `stack'. If `start_min_threads' is TRUE
- this will start `min_threads' many threads immediately. */
- SilcThreadPool silc_thread_pool_alloc(SilcStack stack,
- SilcUInt32 min_threads,
- SilcUInt32 max_threads,
- SilcBool start_min_threads);
-

- and waits that all remaining active threads finish before freeing
- the pool. */
- void silc_thread_pool_free(SilcThreadPool tp, SilcBool wait_unfinished);
-
- /* Run `run' function with `run_context' in one of the threads in the
- thread pool. Returns FALSE if the thread pool is being freed. If
- there are no free threads left in the pool this will queue the
- the `run' and will call it once a thread becomes free.
-
- If `completion' is non-NULL it will be called to indicate completion
- of the `run' function. If `schedule' is non-NULL the `completion'
- will be called through the scheduler in the main thread. If it is
- NULL the `completion' is called directly from the thread after the
- `run' has returned. */

-
- /* Modify the amount of maximum threads of the pool. */
- void silc_thread_pool_set_max_threads(SilcThreadPool tp,
- SilcUInt32 max_threads);
-
- /* Returns the amount of maximum size the pool can grow. */
- SilcUInt32 silc_thread_pool_num_max_threads(SilcThreadPool tp);

- void silc_thread_pool_purge(SilcThreadPool tp);
-
- o Fast mutex implementation. Fast rwlock implementation. Mutex and
- rwlock implementation using atomic operations.
-
- o Compression routines are missing. The protocol supports packet
- compression thus it must be implemented. SILC Zip API must be
- defined.
-
- (o Generic SilcStatus or SilcResult that includes all possible status and
- error conditions, including those of SILC protocol. Though, the SILC
- protocol related status (currently in silcstatus.h) cannot be in
- runtime library) maybe
-
- (o SILC specific socket creation/closing routines to silcnet.h, wrappers
- to all send(), recv(), sendto() etc. Bad thing is that we'd have to
- define all socket options, sockaddrs, etc.) maybe
-
- (o mmap) maybe
-
-
-lib/silcutil/symbian/
-=====================
-
- o Something needs to be thought to the logging globals as well,
- like silc_debug etc. They won't work on EPOC. Perhaps logging
- and debugging is to be disabled on EPOC. The logging currently works
- by it cannot be controlled, same with debugging.
-
-
-SFTP Library, lib/silcsftp/
-===========================
-
- o Read prefetch (read-ahead, reading ahead of time). Maybe if this can
- be done easily.
