Support for other formats was deemed unnecessary in the code review
and therefore removed. The value for the constant TOX_AVATARFORMAT_PNG
is now set in stone; if the other formats become needed again in the
future, this commit shall be reverted and the enum values reordered to
keep compatibility.
Add a protocol and the APIs to straightforwardly support user avatars
in client applications. The protocol is designed to transfer avatars
in background, between friends only, and minimize network load by
providing a lightweight avatar notification for local cache validation.
Strict safeguards are imposed to avoid damage from non-cooperative or
malicious users and to limit network usage.
The complete documentation is available in docs/Avatars.md and sample
code is available in testing/test_avatars.c.
Code and documentation are released under the GNU GPLv3 or later, as
described in the file COPYING.
tox_shell is a basic secure shell that can be used to control a
computer from any Tox client.
Just run tox_shell and make it add your Tox id.
It's very basic but it works.
#if 0 the content of toxav/msi.c : int stringify_message(MSIMessage
*msg, char *dest)
This function has no effect and does not seem to be used for actively
waiting.
Fix various other style errors, reduce scope when possible, avoid
redundant writes, clarify operator priorities, etc.
Added request_id.
request_id must be obtained with tox_generate_dns3_string, stored,
then passed to tox_decrypt_dns3_TXT when we want to decrypt the
received response.
Moved Bunch of functions from net_crypto to crypto_core.
decrypt_data_fast and decrypt_data_symmetric were the same thing
therefore, removed decrypt_data_fast.
Replaced all the crypto_secretbox_* defines with the equivalent
crypto_box_* one.
New define: crypto_box_KEYBYTES that is equal to
crypto_box_BEFORENMBYTES.
From what I see there is a difference between *BSD and Linux when
linking vs. toxcore which has been bulit vs. the NaCl library:
on Linux it only links if NaCl's object files (i.e. randombytes.o) is
present in the linker options, however on *BSD systems this will cause a
linking error, see:
https://github.com/Tox/toxic/issues/31#issuecomment-38224441
This commit makes sure that we do not add the NaCl object files to our
pkg-config settings on *BSD, but do add them on Linux.
Main changes:
1. Strings no longer need to be NULL terminated.
2. tox_get_friend_id is now named tox_get_friend_number.
3. The friend request callback function is now (Tox *tox, uint8_t *,
uint8_t *, uint16_t, void *), the Tox object pointer has been added to
it.
Crash stuff:
nTox.c:
- do_refresh(): avoid crashes (input a "%" and the client goes "boom!", send someone a string with embedded "%" and see him blow up...)
Other stuff:
toxcore: tox.h (doc.)/network.c (code):
- networking_wait_prepare(): return -1 if lenptr was NULL and therefore not settable
nTox.c:
- fraddr_to_str(): function to convert a TOX_FRIEND_ADDRESS into a segmented (and therefore line-breakable) string
- print_friendlist(): print index of friend on name line, print id on 2nd line
- command /f: skip spaces (and +) inside a friend id
- command /r (new): "/r #" to remove a friend
- main(): reduce cpu consumption if we're not currently sending files
On deleting the last peer, it's just a delete.
On deleting any other peer, the last peer is moved into that space, gaining a different number.
Print that detail where appropriate.
tox.*, Messenger.*, group_chats.*:
- expand interface of callback by peernumber/change
groupchats.c:
- call callback in addpeer/delpeer/setnick with peernumber and flag
nTox.c:
- print_groupchatpeers(): print as many names on a line as possible, not one peer per line
- print_groupnamelistchange(): only print the change, if possible (i.e. "new peer", "peer's new name")
- added command "/p" to print the list of peers
/cf # rsp. /cg # sets, /cr resets target
Also reformatted display of sent group message slightly to look less beta-ish.
Then using "#<num>" for group number vs. "<num>" for friend/peer numbers.
Also changed to a slightly different message on people without name.
group_chats.*:
- group_send_nick() to send own name
- setnick() to store a received name
Messenger.c:
- group_send_nick() before group_sendmessage() (in regular intervals, to inform new peers)
nTox.c:
- print_groupmessage(): on error or on a name of length zero the result of tox_group_peername() isn't null-terminated, catch that
- multiple places: tox_getname() doesn't terminate the string, make sure nTox does
- format_message():
. - renamed to print_formatted_message()
. - changed semantics: does the new_line() itself, saves caller from freeing the buffer (which no caller did)
. - changed signature: now also prints the friend's name when sending
. - intern: date is only printed once, the message line gets only time
- print_message(): enforce null termination
- main():
. - setlocale() to init locale (for date/time printing)
. - own name: ensure null termination
Messenger.c:
- notify of friend name change *before* the old name is overwritten
nTox.c:
- flag[]: additional flag for special wrapping
- help expanded and split (to keep below 256 chars)
- new_lines_mark(): stores flag for special wrapping
- print_friendlist():
. - extracted pattern for output
. - added length of id string allocation
. - replaced '\t' with '+ ', wrappers don't account for '\t'
- line_eval():
. - removed a few do_refresh() directly after a new_lines() (calls do_refresh() at its end)
. - 'h' (help): parsing of an additional character for f(riend) or g(roup)
- wrap():
. - the major bugfix:
. - no more endless looping if the input had a substring with no spaces
. for more than line_width (e.g. ID of 78 and window smaller than 78)
- wrap_bars(): wrap() for "rich" messages, honors embedded '\n', breaks preferable at '|'
- print_help(): listed all options and added explanations
- print_invite(): fixed minuscule typo
- main(): made print_help() reachable again
nTox.h:
- majorly cut down to what is really needed
Additionally (besides cleanups):
network.h/tox.h:
- WIN32: fix a strange sa_family_t definition
- WIN32: define EWOULDBLOCK to WSAEWOULDBLOCK
- WIN32: kill macro for an existing function (IN6_ADDR_EQUAL)
network.c:
- use EWOULDBLOCK instead of EAGAIN (same value, but EWOULDBLOCK is more "popular")
- new_networking(): only try to enable IPv4-in-IPv6 if it's not already enabled per default
- inet_ntop()/inet_pton(): WIN32: remove partial initializers in favor of a simple memset()
- ip_equal(): WIN32: use an existing function
- logging: networking_wait_execute(): only dump result if not timeout
- logging: loglogdata(): kill an unused variable
LAN_discovery.c:
- send_broadcasts(): re-enabled, can only support IPv4 by principle, split into fetch_broadcast_info() (to fetch the addresses once) and send_broadcasts() (actual sending)
DHT.c:
- DHT_load_state_callback(): enclosed a fprintf(stderr, ...) into #ifdef DEBUG
Lossless_UDP.c:
- change_handshake(): harden against strange sa_family_t definitions
Messenger.c:
- logging: fix ID to string conversion
util.c:
- logging: eliminate a signed-warning
Tox sync is a proof of concept bittorrent sync inspired application that
uses tox to sync the contents of two folders.
Currently only works on POSIX compilant operating systems.
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.)
Moves static state out of Messenger.c and into a Messenger struct
Purely stylistic, no functional changes were made.
This commit also changed all the callers of Messenger as they now have
to pass an instance of the Messenger struct to messenger functions.
Also removed some uses of the 'static' keyword at the beginning of
function definitions when the function was already declared static, as
these caused gcc to whine.
