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.
According to sonOfRa sodium_init() has some timing issues on Android.
libsodium people said randombytes_stir() can be used instead:
https://github.com/jedisct1/libsodium/issues/121
sodium_init() stays the default, randombytes_stir() can be enabled by
passing --enable-randombytes-stir to the configure script.
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
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
network.*:
- sendpacket(): checks result and on EAGAIN, stores time of this event
- networking_wait_prepare(): uses the time if set to check up to 500ms later for the socket to be writeable again
- networking_wait_cleanup(): clears the time if the socket was writeable
- fixed some accidental tabs
Messenger.*, tox.*:
- pass-through functions to reach networking_wait_cleanup()
- fixed some accidental tabs
To allow the actual waiting to run without any locking, split it into preparing the data it uses and the execution of the wait.
The caller must provide with the buffer to store whatever data it requires to wait.
Completely eliminates any reliance on the existence of anything but that data in the actual wait routine.
Also fixed a few argument type warnings inside LOGGING.
Lossless_UDP.*:
- sendqueue_total() sums sendqueue() across all connections
network.*, Messenger.c:
- sendqueue_total() is collected and then used in deciding if we select() on write-readiness
tox.*, Messenger.*, network.*;
- new function tox_wait() => waitMessenger() => networking_wait():
- waits for a given amount of time for any sort of socket activity
- mustn't change anything inside, mustn't poll or do other stuff
- the point is to be able to call this asynchronously from a second thread
- the outside shall follow up with an immediate tox_do() when there's socket activity
tox.*:
- allow inclusion of tox.h into tox.c, ensuring that the outside interface and the internal always match
util.c:
- squished a few warnings about questionable format strings
util.c:
- handle loglog() before loginit() by storing the lines into an expanding buffer
- when loginit() is called, write out and kill the buffer
network.c:
- push loginit() to the point where we know the actually used port
