Previously, the `ipv6` variable was initialised to `-1`, but that value
was never read. Either it was set to 0 or 1, or the function would return
before it was read. Thus, I've changed it to uninitialised `bool is_ipv4`
(inverted semantics to avoid negative conditions `if (!is_ipv6)`).
The `pack_ip_port` function is a bit unfortunate, but I'm not rewriting
it until we have a binary writer (I'd be rewriting it twice).
`new_nonce` has been an alias for `random_nonce` for a while now. Having
two names for the same operation is confusing. `random_nonce` better
expresses the intent. The documentation for `new_nonce` talks about
guaranteeing that the nonce is different from previous ones, which is
incorrect, it's just quite likely to be different.
These definitely don't belong in a module called "crypto core". The DHT
module seems like the best place to put them, since they are sent to DHT
nodes.
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.
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 header is a requirement for the public API, therefore is assumed to
exist. It is a C99 standard library header, and _Bool is not intended to
be used directly, except in legacy code that defines bool (and
true/false) itself. We don't use or depend on such code. None of our
client code uses or depends on such code. There is no reason to not use
bool.
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.
- 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.
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.
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.
- 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.
