These were generated by the autotools build. Some clients may depend on
these files instead of the newer split pkg-config files. New clients
should be using the toxcore, toxav, toxencryptsave, and toxdns modules.
We also never really tested this, because we run make distcheck, which
does another configure with default flags instead of the ones we passed.
Fixes#317.
Having -Werror set by default causes users' builds to fail because
toxcore is not warning-free. Failing on errors is appropriate for the
development phase, e.g. when building it in a CI enviroment, but it
doesn't make much sense to fail builds for users and let them figure out
that they need to pass -DWARNINGS=OFF to make the library build.
Compiling as C++ changes nothing semantically, but ensures that we don't
break C++ compatibility while also retaining C compatibility.
C++ compatibility is useful for tooling and additional diagnostics and
analyses.
We use TRACE=ON (cmake flag) to enable LOG_TRACE. This way, a regular
build can enable DEBUG while not paying the price of TRACE. This is
particularly important for FFI bindings (especially Python), where
invoking callbacks can be an expensive operation.
When cross-compiling to <target> from Linux, cmake might find native Linux
libconfig and decide to build tox-bootstrapd. If the target is Windows, this
will fail, as tox-bootstrapd can't be built for Windows in the first place. If
the target is Linux of some other architecture, then using host native
libconfig will fail too. Thus an option is needed to guard against this.
- Moved apidsl headers next to their generated versions. In the future,
perhaps all (or most) headers will be apidsl-generated, so the sources
should stay together.
- Try to find apidsl/apigen binary and astyle binary and use it for the
format test. Don't run the format test if these can't be found.
- Fixed incorrect parameter names (documented name didn't match code
name).
- Removed `@return` from functions that return `void`.
- Make sure every parameter is documented. This required moving the
planes and strides documentation to the function docs.
It is still C code, so still compatible with C compilers as well. This
change lets us see more clearly where implicit conversions occur by
making them explicit.
- All global variables should be static unless they have an explicit
extern declaration in a header file.
- `to_compare` was not used in encryptsave and toxav tests.
- `break` in switch cases is not required directly after `return`,
`goto`, or a noreturn function like `abort`.
Enabling this flag will generate and use an LD version script. It
ensures that the dynamic libraries (libtoxcore.so, libtoxav.so) only
export the symbols that are defined in their public API (tox.h and
toxav.h, respectively).
In the future, all TODOs added either need a bug number (TODO(#NN)) or a
person's github user name. By default, I made irungentoo the owner of
all toxcore TODOs, mannol the owner of toxav TODOs, and myself the owner
of API TODOs.
This test is already performed by `make test` later on. We originally
had it in the Travis script to make it fail fast when the format is
wrong, but there is also some value in running all tests despite format
errors.
Fixes#83. There are no more relevant phases that would benefit from the
padding lines proposed.
It now enforces a bit more formatting. In particular, padding inside
parentheses is removed. I would like it to remove padding after unary
operators, but there seems to be no option for that.
I hadn't done this for the "fun" code, yet. Also, we should include
system headers after our own headers.
"In general, a module should be implemented by one or more .cpp files.
Each of these .cpp files should include the header that defines their
interface first. This ensures that all of the dependences of the module
header have been properly added to the module header itself, and are not
implicit. System headers should be included after user headers for a
translation unit."

- Any non-externally-visible declarations should be `static`.
- Casting away the `const` qualifier from pointers-to-const is
dangerous. All but one instance of this are now correct. The one
instance where we can't keep `const` is one where toxav code actually
writes to a chunk of memory marked as `const`. This code also assumes
4 byte alignment of data packets. I don't know whether that is a valid
assumption, but it's likely unportable, and *not* obviously correct.
- Replaced empty parameter lists with `(void)` to avoid passing
parameters to it. Empty parameter lists are old style declarations for
unknown number and type of arguments.
- Commented out (as `#if DHT_HARDENING` block) the hardening code that
was never executed.
- Minor style fix: don't use `default` in enum-switches unless the number
of enumerators in the default case is very large. In this case, it was
2, so we want to list them both explicitly to be warned about missing
one if we add one in the future.
- Removed the only two function declarations from nTox.h and put them
into nTox.c. They are not used outside and nTox is not a library.
