Also started teaching it about toxcore's alloc/dealloc functions in
hopes of it catching some errors (it doesn't seem to be very good at
this, but maybe better than nothing?).
We now depend on libsodium unconditionally. Future work will require
functions from libsodium, and nobody we're aware of uses the nacl build
for anything other than making sure it still works on CI.
It doesn't work, because esp32 has too little RAM (320KB). DHT is a
240KB struct, so even just allocating that immediately fails. We'll need
to think carefully about trimming that if we ever want this to work on
embedded devices.
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.
cmake treats the provided path differently depending on whether it
contains a CMakeCache.txt or not. If it doesn't contain it -- it's
treated as a path to the source tree, if it does -- as a path to the
build tree. We want it to be treated as a source tree path, but if a
user has CMakeCache.txt in that directory, e.g. from a previous in-tree
build the user has done, cmake will treat it as a build tree instead,
which might lead to unexpected results (improperly configured build) or
an error, with the latter being more likely considering we are building
inside a container and the host paths specified in the user-generated
CMakeCache.txt likely don't exist in there.
Disabled a whole bunch of rules from the MISRA-C set. Some of them
should be fixed, but most of the ones we violate have good reasons. This
PR documents those reasons.
Needed for the build afterwards.
Also added the cflite Dockerfile to automatic CI builds so changes to it
are checked in pull requests.
Also fixed the tokstyle docker image. It needs clang instead of gcc now.
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`.
