2016-09-06Improve static and const correctness.iphydf
- 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.
2016-09-06Make friend requests statelessGregory Mullen (grayhatter)
Messenger is slightly twisty when it comes to sending connection status callbacks It will very likely need at the very least a partial refactor to clean it up a bit. Toxcore shouldn't need void *userdata as deep as is currently does. (amend 1) Because of the nature of toxcore connection callbacks, I decided to change this commit from statelessness for connections changes to statelessness for friend requests. It's simpler this was and doesn't include doing anything foolish in the time between commits. group fixup because grayhatter doesn't want to do it "arguably correct" is not how you write security sensitive code Clear a compiler warning about types within a function.

We'll revert this once we move to clang-format.
2016-08-31Add braces to all if statements.iphydf
2016-08-27Move logging to a callback.iphydf
This removes the global logger (which by the way was deleted when the first tox was killed, so other toxes would then stop logging). Various bits of the code now carry a logger or pass it around. It's a bit less transparent now, but now there is no need to have a global logger, and clients can decide what to log and where.

2016-08-17Add missing DHT_bootstrap to CMakeLists.txt.iphydf
- This PR also adds a DEBUG cmake option that enables -DTOX_DEBUG. - We also remove `-Wall`, because there are too many warnings, and nobody really looks at them at the moment. We'll see about fixing them soon. We'll also want to enable `-Werror` at some point. - Finally, this PR enables `-O3` to make sure toxcore still works correctly under heavy compiler optimisations.
2016-08-17Make self_connection_status callback stateless.iphydf
**What are we doing?** We are moving towards stateless callbacks. This means that when registering a callback, you no longer pass a user data pointer. Instead, you pass a user data pointer to tox_iterate. This pointer is threaded through the code, passed to each callback. The callback can modify the data pointed at. An extra indirection will be needed if the pointer itself can change. **Why?** Currently, callbacks are registered with a user data pointer. This means the library has N pointers for N different callbacks. These pointers need to be managed by the client code. Managing the lifetime of the pointee can be difficult. In C++, it takes special effort to ensure that the lifetime of user data extends at least beyond the lifetime of the Tox instance. For other languages, the situation is much worse. Java and other garbage collected languages may move objects in memory, so the pointers are not stable. Tox4j goes through a lot of effort to make the Java/Scala user experience a pleasant one by keeping a global array of Tox+userdata on the C++ side, and communicating via protobufs. A Haskell FFI would have to do similarly complex tricks. Stateless callbacks ensure that a user data pointer only needs to live during a single function call. This means that the user code (or language runtime) can move the data around at will, as long as it sets the new location in the callback. **How?** We are doing this change one callback at a time. After each callback, we ensure that everything still works as expected. This means the toxcore change will require 15 Pull Requests.
