1 SILC Runtime Toolkit 1.2 and beyond
2 ===================================
4 NOTE: Any item that doesn't have (***DONE) in it, isn't done yet. The
5 (***TESTING NEEDED) means that the item has been done but not yet properly
8 NOTE: A TODO entry does not mean that it is ever going to be done. Some
9 of the entries may be just ideas, good, bad or ugly. If you want to work
10 on some of the TODO entries simply let us know about it by dropping a note
11 to silc-devel mailing list or appear on 'silc' channel on SILCNet.
17 o Create apps/tutorial containing various Toolkit API tutorials.
19 o The Toolkit split. The Toolkit is to be splitted in parts. How many
20 parts and what the parts are isn't decided yet. Each part is a separate
21 software package. Current thinking is of the following:
23 SILC Toolkit SILC protocol, client and server library
24 SILC Runtime Toolkit runtime library
25 SILC Crypto Toolkit crypto, asn1, math, skr, pgp, etc.
27 The rationale for this is of course that other than SILC projects
28 might like to use the various libraries SILC Toolkit provides, but
29 naturally they don't want the bloat of SILC protocol related stuff.
31 The Runtime library in SILC Toolkit is a general purpose runtime library,
32 like Glib and APR are. The runtime library is to be developed further
33 to provide alternative to Glib and APR.
35 The Crypto library in SILC Toolkit is a general purpose crypto library
36 providing pretty nice APIs compared to many other crypto libraries,
37 especially OpenSSL. The Crypto library is to be developed further
38 to include support for OpenPGP, X.509 and SSH2.
41 Runtime library, lib/silcutil/
42 ==============================
44 o Unix socket support to Socket Stream API (local socket stream).
46 o Simple SILC Rand API for pseudo-random numbers. (***DONE)
48 o file removing, chmod, rmmod, etc. chdir, rmdir, stat, etc. to
49 lib/silcutil/silcfileutil.h.
55 o Implement silc_get_num_cpu.
57 o silc_file_readfile and silc_file_writefile should perhaps do the thing
58 with mmap, as it's probably a bit faster.
60 o silc_malloc et. al. to respect --with-alignment.
62 o Fix universal time decoding (doesn't accept all formats) in silctime.c.
64 o Additional scheduler changes: optimize silc_schedule_wakeup. Wakeup
65 only if the scheduler is actually waiting something. If it is
66 delivering tasks wakeup is not needed.
68 o silc_stringprep to non-allocating version.
70 o Add builtin SOCKS and HTTP Proxy support, well the SOCKS at least.
71 SILC currently supports SOCKS4 and SOCKS5 but it needs to be compiled
74 o Add directory opening/traversing functions (***DONE, TODO Windows & Symbian)
76 o regex from /lib/contrib to lib/silcutil, define SILC Regex API. (***DONE)
78 o Add functions to manipulate environment variables. (***DONE)
80 o Add functions to loading shared/dynamic object symbols (replaces the
81 SIM library (lib/silcsim) and introduces generic library). Add this
82 to lib/silcutil/silcdll.[ch]. (***TESTING NEEDED WIN32, TODO Symbian)
84 o silc_getopt routines (***DONE)
86 o The SILC Event signals. Asynchronous events that can be created,
87 connected to and signalled. Either own event routines or glued into
88 SilcSchedule. (***DONE)
90 o If the event signals are added, the SILC_PARAM_* stuff needs to be
91 moved from silcbuffmt.h to silctypes.h or something similar. (***DONE)
93 o In case the SILC Events are done we shall create a new concept of
94 parent and child SilcSchedule's. When new SilcSchedule is created a
95 parent can be associated to it. This association could be done either
96 directly by the parent or by any other children. This way the signals
97 would in effect be global and would reach all children schedulers.
99 This relationship would be associative only. The schedulers are still
100 independent and run independently from each other. All schedulers
101 would be linked and could be accessed from any of the schedulers.
102 It should be possible to retrieve the parent and enumerate all children
103 from any of the schedulers.
106 o Base64 to an own API (***DONE)
108 o Timer API (***DONE)
110 o silc_hash_table_replace -> silc_hash_table_set. Retain support for
111 silc_hash_table_replace as macro. (***DONE)
113 o SilcStack aware SilcHashTable. (***DONE)
115 o SilcStack aware SilcDList. (***DONE)
117 o Thread pool API. Add this to lib/silcutil/silcthread.[ch]. (***DONE)
119 o Add new functions to SilcStack API in lib/silcutil/silcstack.[ch]. Add
120 silc_stack_[set|get]_alignment. It defines the default alignment used
121 when allocating memory from stack. It can be used to specify special
122 alignments too when needed (such as for hardware devices like crypto
123 accelerators). Move also the low level silc_stack_malloc and
124 silc_stack_realloc from silcstack_i.h to silcstack.h. Remove the
125 _ua unaligned memory allocation routines. Remove unaligned memory
126 allocation possibility. (***DONE)
128 o silc_stack_alloc shouldn't require multiple by 8 size argument, it
129 should figure it out itself. (***DONE)
131 o Add '%@' format to silc_snprintf functions.
134 o SILC Tls (Thread-local storage) API to lib/silcutil/silcthread.[ch].
137 o Change silc_gettimeofday on Unix to use clock_gettime with REALTIME
138 clock if it is available, otherwise use gettimeofday(). (***DONE)
140 o Generic SilcResult that includes all possible status and
141 error conditions and generic errno API. (***DONE)
143 (o Structured log messages to Log API. Allows machine readable log
144 messages. Would allow sending of any kind of data in a log message.) maybe
146 (o Change some stream routines (like socket stream API) to accept ANY
147 stream and use silc_stream_get_root to get the socket stream from the
148 given stream. This will make various stream APIs more easier to use
149 when user doesn't have to dig up the correct stream.
151 Add silc_stream_get_root and add get_root stream operation. It
152 returns the root of the stream or NULL if stream doesn't have root.) maybe
154 (o Compression routines are missing. The protocol supports packet
155 compression thus it must be implemented. SILC Zip API must be
158 (o SilcIpAddr abstraction. Ipv4 and Ipv6 support to the abstaction.)
161 (o SILC specific socket creation/closing routines to silcnet.h, wrappers
162 to all send(), recv(), sendto() etc. Bad thing is that we'd have to
163 define all socket options, sockaddrs, etc.) maybe
165 (o Fast mutex implementation. Fast rwlock implementation. Mutex and
166 rwlock implementation using atomic operations.) not for now.
176 o Something needs to be thought to the logging globals as well,
177 like silc_debug etc. They won't work on EPOC. Perhaps logging
178 and debugging is to be disabled on EPOC. The logging currently works
179 by it cannot be controlled, same with debugging. SILC Global API
180 MUST be used with all globals on Symbian.
182 o gethostname() returns "Function not implemented". Others may return
183 the same. We should fix that probably to use RHostResolver and
186 o silc_thread_exit should call User::Exit().
