Currently only `crypto_core_mem.c` needs this. We should try not to
depend on configure'd values. Also note: config.h is only created and
used in the autotools build. In CMake, we pass `-D` flags directly.
We now either log errors or properly propagate them. In the case of
ping_send_request we make the function return void because it doesn't
seem to matter whether or not it succeeds.
The assert was removed, because it triggers as soon as the padding bytes
in the struct Saved_Friend are non zero. The Tox specification doesn't
say anything about the value of these bytes, so we should just ignore
them.
In the "no proxy" case, the `IP_Port` in the default "no proxy" default
proxy info is uninitialised. It is never used for any decisions in the
code, but it is copied in memory, making it a potential crash on systems
with trap representations of ints.
The android warnings are disabled now because they suggest using
linux-only extensions of libc. Useful for android indeed, but we're
targeting non-android and non-linux systems as well.
All for-loops must have an init-decl, a condition, and an increment
statement. Any loop that doesn't have one of these should be a while
loop (only 2 of these exist in toxav, none in toxcore).
This makes the code a little more flat and readable. We also change the
logic so that we can kill the necessary number of unused relays immediately
rather than having to collect them and remove them in a separate loop
In this case, there was no way it would not be, but a code change down
the stack could cause a variable to become uninitialised. This avoids a
gcc warning and is more locally-correct.
We used to have lots of these in the code, but now that all the endian
stuff is no longer dependent on host byte order, we can re-enable the
warning flag and catch any future violations.
CRYPTO_SIZE is used in a subtraction as second argument and instead of
subtracting then intended value only '1' is subtracted due to operator
precedence rules and missing braces.
Mono_Time needs to acquire a lock each time one of its functions are
used. This becomes very costly in the DHT code where timeouts for all
connected nodes are recalculated. Improve this by caching the timestamp
at the begin of a do_dht() iteration.
- Properly handle crypto_connection_status() failure
- Remove CONNECTION_UNKNOWN and restructure surrounding logic so that
the API no longer reports erroneous friend connection statuses
The test explicitly wanted a UDP connection when a TCP connection would suffice. This
was a remnant of back when the test was part of a multi-purpose autotest that
didn't attempt to connect to TCP relays and needed a UDP connection specifically.
