refactor: Use cmp instead of msgpack-c for events packing.
This library is better in every way.

cleanup: Remove redundant Messenger and DHT tests.
These don't test anything that isn't covered by higher level tox tests.
These are also not unit tests and have never found any bug that wasn't
also caught by other tests. This makes them a pure maintenance burden.

cleanup: Enable most cppcheck warnings as errors.
Cleaned up some of the warnings it gives. Disabled the ones that are
less useful for us at this time.

cleanup: Don't use VLAs for huge allocations.
One of these was creating a single 262144 byte stack frame. We now have
a way to check and limit the allocation size of a VLA. The `Cmp_Data`
ones were also fairly large. Now, no allocation is larger than 2KiB
(though rtp.c allocates close to that much).

cleanup: Add nonnull annotations to function definitions.
These help static analysis and ubsan. We should eventually have all
functions annotated like this with a cimple check to make sure every
pointer has an explicit nullability annotation. The `nullable`
annotation does nothing in GCC, but will be used by cimple to validate
that every parameter has defined nullability.

feat: Add binary packing functions for tox events. 2022-02-07 02:43:24 +00:00

feat: Add async event handling (callbacks) code.
Instead of synchronously handling events as they happen in
`tox_iterate`, this first collects all events in a structure and then
lets the client process them. This allows clients to process events in
parallel, since the data structure returned is mostly immutable.

This also makes toxcore compatible with languages that don't (easily)
support callbacks from C into the non-C language.

If we remove the callbacks, this allows us to add fields to the events
without breaking the API.

cleanup: Ensure we limit the system headers included in .h files.
Most system headers contain functions (e.g. `memcpy` in `string.h`)
which aren't needed in our own header files. For the most part, our own
headers should only include types needed to declare our own types and
functions. We now enforce this so we think twice about which headers we
really need in the .h files.

cleanup: Remove uses of strcpy and sprintf.
Use of `strcpy` in these particular cases was safe, but it's hard to
tell and also useless. `strcpy` would effectively need to do another
`strlen` which we already did.

Also removed sprintf, which was also safe in this case but it's easier to
be "obviously safe", especially for static analysers.

chore: Run static analysers in multiple variants.
Currently: 1) libsodium and 2) nacl.

Note that the "nacl" variant is actually libsodium. We just want to make
sure the static analysers see the `VANILLA_NACL` code paths.

chore: Disable -Wmissing-braces.
This flag isn't helpful for the most common case of aggregate
initialisation, namely `{0}`. We don't want to be writing `{{{0}}}` with
some brittle number of braces.

cleanup: Fix some clang-tidy warnings and make them errors.
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.

cleanup: Ensure that error codes are always initialised.
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.

cleanup: Fix last instance of -Wcast-align and enable the warning.
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.

Add a check that we don't have any unused functions.
This check puts all of our code in a C++ anonymous namespace, which is
effectively making all functions `static`. This allows the compiler to
determine that a function is unused, so we can delete it.

Add tool to find directly recursive calls in toxcore.
We should avoid recursion, as it makes reasoning about stack growth
harder. This tool shows (currently) 4 (non-tail) recursive functions, at
least 2 of which are easy to fix.

Make a separate struct Tox containing the Messenger.
This allows Tox to contain additional data on top of Messenger, making
Messenger not necessarily the most top-level object. E.g. groups are
built on Messenger and currently awkwardly void-pointered into it to
pretend there is no cyclic dependency.
