State loading/saving: Instead of a blob, segment into sections marked with tags.
|
|
|
|
Messenger.c:
- additional size checks
- removed one pointless copying of data, instead using it directly
util.c:
- lost a newline vs. master

Fix in ip_equal, plus testing code which led to that fix...
|
|
network.c:
- use the correct macro for IPv4-in-IPv6 test
network_test.c:
- bunch of tests for addr_resolve() and ip_equal()

struct in6_addr member names can differ per platform.
|
|
|
|
network.c:
- ip_equal(): on IPv4 vs. IPv6, check if the IPv6 is an embedded IPv4 and if true, compare that
|
|
network.c:
- addr_resolve(): save AF_UNSPEC ip4 address into ip4, not into to->ip4
|
|
Also fixed the "[i] could not send message" bug in nTox.

- get_close_nodes(): refactored the inner loop out into get_close_nodes_inner()
|
|
- addr_resolve(): for() instead of while(), flip conditions for a much neater function (suggested by Andreas Schneider)
- ip_ntoa(): enforced termination: terminate at the maximum position, that's the one snprintf() may forget
- networking_poll(): forgot tabs2spaces
|
|
- LAN_ip(): use standard macro from IPv4-in-IPv6 test
|
|
- get_close_nodes()/sendnodes()/sendnodes_ipv6(): when selecting for SEND_NODES/SEND_NODES_IPV6, treat embedded IPv4-in-IPv6 addresses as being IPv4
Messenger.c:
- added a named constant for sixty seconds friend/client dump
- fix logging to convert client_id to printable before printing

65536) friends...

Primary rationale: The part that DHT saves changes if IP is expanded to IPv6. To let people keep their friends/name, change the datafile format now, while everybody is still on the same page.
Loading/Saving rewritten to allow a part of the file to be incomprehensible to the loading routine.
Added a magic cookie at the beginning to mark the file as tox's.
Changes in some part of the datafile can be skipped and the remaining parts still be consumed.
Allows a wide margin of forward compatibility (like the IP to IPv6 transition, but also e.g. a change in the key format).
As long as the file is not completely garbled, the routine will read as much as possible. Only the KEY section is considered mandatory: a malformed key section leads to a negative result.
util.*:
- holds the driving function which jumps from section to section and calls back with section length and tag (type)
Messenger.c,DHT.*:
- new loading functions call the util-function with a callback, which subsequently consumes the sections
- old routines are kept to fall back onto if the magic cookie at the beginning isn't present
- saving is still done in one local routine

Nonces don't need to be random, only different.
also random_int now gives same quality random numbers for both NaCl and
libsodium.

messages.

Group chats are not complete, they seem to work very well though.
This means that the functions will change.
|
|
|
|
Please wait until the tox.h API is updated before integrating it into
your clients.
nTox:
/g
creates a new group chat
/i friendnum groupnum
invite friendnum to groupnum
/z groupnum message
send message to groupnum
NOTE: group chats currenly might not handle packet loss well if there are less than 6 participants.

This patch inserts LAN discovery in DHT_bootstrap, allowing it to find clients even if it's run parameterless (and clients don't connect to it directly, e.g. because the port is already bound to a different client).
- moves the #define of LAN_DISCOVERY_INTERVAL from Messenger.c to LAN_discovery.h
- includes LAN_discovery.h into DHT_bootstrap.c
- DHT_bootstrap.c sends and accepts LAN_discovery packets
|
|
- addr_resolv(_or_parse_ip)(): added an optional parameter to return both an IPv6 and an IPv4 address if requested address family was AF_UNSPEC
- logging of unhandled packets
DHT.c:
- bootstrap_from_address(): use the additional return from addr_resolv_or_parse_ip() to bootstrap in both network types at once
Lossless_UDP_testclient.c:
- main(): adapt to signature change of addr_resolve()
Messenger.c. LAN_discovery.h:
- lost a htons(), readded
- moved LAN_DISCOVERY_INTERVAL #define into LAN_discovery.h
LAN_discovery.c:
- added IPv4-in-IPv6 local address test
|
|
- remove local PORT definition in favor of TOX_PORT_DEFAULT
|
|
- #define'd tox's network port (as range)
- finally killed tox_new_ex() in favor of changing tox_new()'s signature
- renamed tox_bootstrap() to tox_bootstrap_from_ip()
network.h:
- #define'd tox's network port (as range)
- renamed SEND_NODES_EX to SEND_NODES_IPV6
- bind() loop uses #define'd port range
DHT.c:
- renamed SEND_NODES_EX to SEND_NODES_IPV6
- sending ipv6 node addresses even if can't use them ourselves
nTox.c:
- adapted to changed tox_new()
|
|
|
|
|
|
- removed almost unused variable without further use
|
|
- unbroke Messenger_load(): lost a length adjustment
- addeditional check for enough data available
|
|
- tox_bootstrap_ex(), DHT_bootstrap_ex() renamed to tox_bootstrap_from_address(), DHT_bootstrap_from_address()
- (handle_)sendnodes_ex() renamed to (handle_)sendnodes_ipv6()
- only sending sendnodes_ipv6() if we're actually IPv6 enabled
- changed comments to conform better
nTox.c, Messenger_text.c, DHT_test.c, DHT_bootstrap.c:
- fallout from *_ex() to *_from_address()
DHT_bootstrap.c:
- corrected a potentially wrong info message
util.c:
- fixed logfile name: now (funcptr) => now() (number)
network.c:
- addead comment about the necessity of bind() to succeed
auto_test/messenger_test.c:
- defaulting ipv6enabled to TOX_ENABLE_IPV6_DEFAULT
LAN_discovery.c:
- slight cleanup and comments for clarity
