Instead of using `target_link_modules`, which does magic that we no
longer need, because we only have 1 library we install, and all binaries
we build link statically because they need access to internal symbols.
This mainly saves spam in test logs, but may save some packets here and
there, if nodes are randomly selected twice for GET_NODES and onion
routing packets.
This allows client developers to use the private API without
needing to manually specify the header path in the source
code, which may vary from system to system.
It doesn't work at all, because we're missing something in the net code
to do with endian conversions. I haven't investigated, yet, but at least
now we have a failing test that can be investigated.
Also moved to cmake 3.5 at minimum. CMake will stop supporting lower
versions than that, soon.
Also moved to C11 from C99 to get `static_assert`.
Also made a network ERROR into a WARNING. It triggers on FreeBSD.
This is the "server-side" part of the new friend finding system,
allowing DHT nodes to store small amounts of data and permit searching
for it. A forwarding (proxying) mechanism allows this to be used by TCP
clients, and deals with non-transitivity in the network.
Nothing checks whether these layers are actually observed. The bazel
build does check this, so there's no need to have this documentation in
the cmake build. It'll just go out of date.
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.
This uses mallocfail to further increase coverage using the existing
tests. Also:
* Moved the non-auto "tox_one_test" to gtest. This should be
split into smaller tests later.
* Changed `hole_punching` to `bool`.
tox_unpack is for unpacking Tox types, and bin_unpack is for
unpacking ints and binary data. This prevents us from creating
dependency cycles due to tox_unpack depending on tox.h
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.
