Compilerflag: CLIENT_ONETOONE_IP (to define in DHT.h, default unset i.e. NEW case: two addresses)
Every function in DHT{_test}.c working on Client_data has been rewritten to store IPv4 addresses in assoc4, IPv6 addresses in assoc6.
Loading/Storing of states defined with other compiler switch is transparently adjusting to the differences.
DHT.h, DHT.c:
- introduction and handling of the structure changes
DHT_test.c, Messenger.c:
- logging adapted to new structures
util.h:
- LOGGING isn't undefined per default anymore
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.
- 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
- #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()
- correct a message who claims we're going to exit when we actually aren't
- don't treat a failed close on reading the data file as failure of the reading
- don't claim "Added friend" per default, check for returned ID first
- on '/q' SAVE... else everything but the keys is lost on each restart
- for that, split load_key() into load_data() and save_data()
- announce own nickname on startup
- 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
- return to the caller if the string could be resolved into an IP
other/DHT_bootstrap.c, testing/*_test.c, testing/nTox.c:
- parse cmdline for --ipv4/--ipv6 switch to allow user a choice
util.h:
- proper old-style C-comment
- initialisation: argument added to enable/disable ipv6 as socket
Messenger_test.c:
- initialisation: ipv4 hardcoded for now
- delegating IP resolution to DHT_bootstrap_ex()
By default libsodium is used. Only if --enable-nacl is specified, then
nacl will be used instead of libsodium.
Pass locations of nacl headers and libraries by using the following
options:
--with-nacl-headers=/home/me/somewhere/nacl-20110221/build/469/include/amd64/
--with-nacl-libs=/home/me/somewhere/nacl-20110221/build/469/lib/amd64/
This update makes sure that the build still works with automake prior to
1.12 and at the same time does not give any warnings or errors with
automake 1.14
supported options:
--with-dependency-search=DIR will tell configure to look for various
dependencies in DIR/include and DIR/lib
Alternatively you can also specify libsodium header and libs location
with --with-libsodium-headers and --with-libsodium-libs if it is
installed elsewhere.
Ncurses and libconfig are handled via the default pkg-config way, see
./configure --help=short for detailed information.
The tox library is compiled as libtoxcore in shared and static variants,
public headers are installed to ${prefix}/include/tox
A pkg-config libtoxcore.pc configuration file is provided.
Use ./configure --help for a full list of configure options or
./configure --help=short for the options that I added.
To generate the configure script after pulling from git use:
autoreconf -i
To generate a release tarball use:
make dist
Unit tests are handled by the libcheck library integration that is provided
by autotools, use:
make check
to compile and run the tests.
Unit tests are currently optional, i.e. - if the check library is not
found on the system, then tests will be disabled. Same goes for nTox and
DHT bootstrap daemon - they will be enabled or disabled depending on the
availability of ncurses (for nTox) or libconfig (for DHT bootstrap
daemon).
The above can be also tuned by:
--enable-tests / --disable-tests
--enable-ntox / --disable-ntox
--enable-dht-bootstrap-daemon / --disable-dht-bootstrap-daemon
While doing the checks configure might generate "core" files and will
then try to remove them. Having a "core" directory generates an error
while runing the configure script.
There's no workaround but to rename the core directory.
Set current locale, use of get_wch instead of getch for reading, use
wctomb and friends to convert back from wchar_t, link with
cursesw. Unicode support is only added to chat windows.
Crypto requests packets are packets that can be routed by nodes in the
DHT. In this pull request I have merged both Natping requests and friend
requests into one common packet (Crypto request packets). Both these
packets should now only be distinguishable by the size of the data in
them to an outside observer for an example on how to send and recieve
data with these packets see: friend_requests.c
Note that these packets are prefixed with id 32 (friend request packets)
which means this change is compatible with the currently running DHT
bootstrap servers.
Also changed small thing in DHT_test.c
The friend address is what the byte string that you give away for people
to add you will be called.
1. Every friend address now contains a number set by the friend. This is
to prevent someone from randomly spamming people in the DHT with friend
requests and makes it so you need the person to actually give you the
address in some way to send the friend request. This number is expected
to be encrypted with the friend request. All requests that do not
contain this number will be rejected. This means the spammer can no
longer use the DHT to collect lists of valid addresses to spam. It also
enables users to quickly change the number in case a spammer gets hold
of the address and starts spamming it.
2. A 2 byte checksum will be added (not implemented yet) to prevent
people from accidentally adding random strings as friends. (NOTE that
this has nothing to do with the spam problem I just decided to add a
placeholder for it now.)
