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 It'll just go out of date.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.
* `crypto_memcmp` was replaced by more specific functions. We never want
to compare arbitrary amounts of data this way. We use these functions
to compare key material.
* apidsl has been bothering people, so now we un-bother them. You're
welcome.
* Added the memlock/unlock functions from the New Group Chats branch.
* Remove some system dependencies in crypto_core_mem.c.
* Renamed UPPERCASE_NAMES to Snake_Camel_Case names.
- more inteligent secret key generation
- use OpenMP for multithreading
- leave old cracker, because it's simple
- update old cracker to new coding style
Apidsl is not powerful enough to express all the things we need and
doesn't know how `#include` works. The generated headers are more complex
than they should be.
* Don't overwrite the CMAKE_MODULE_PATH
* Allow linking libsodium statically with MSVC
* Allow finding libsodium the normal way on MSVC
* Allow using pthreads4w for pthreads on MSVC
* Fall back to find_package if pkg_find_module fails
* Don't pass incompatible compile flags to MSVC
* Also try to find Opus and libvpx using their canonical names
* Support building using conan
* Allow pkg_use_module to take a list of libraries to look for
* Build for Windows on Appveyor using conan
This allows invitations to work in the case that the invitee is already
in the group, which can happen if the group becomes split. Such an
invitation is automatically accepted, leading to the peers becoming
connected in the group and sharing peer lists.
