Diadlo ffcee69db9 Extract 'update_client_with_reset' function to reduce code duplication 2017-06-05 02:02:33 +03:00
Diadlo 0eaa44650f Extract 'update_client' function

Diadlo 69c71ddd23 Change return type to be the same as return value type
Return value of 'addto_list' function is 'used' counter, which is uint32_t.
It will be better to use the same return type.

iphydf 1e8fa85aad Add a monolith_test that includes all toxcore sources.
This requires that every symbol, even if static (file-scope), is unique.
The idea is that we can easily run "whole" program static analysis on
programs that include monolith.h ("whole" is in quotes, as we don't
include dependencies like libsodium in this static analysis).

iphydf 8f96ca6d86 Update license headers and remove redundant file name comment.
"All rights reserved" was incorrect. The project was licensed under GPL3,
which means a lot of rights are licensed to everybody in the world, i.e.
not reserved to the "Tox Project".

iphydf 8b4eae4038 Remove TOX_DEBUG and have asserts always enabled.
These are cheap asserts. I've also replaced the fprintf's with
`LOGGER_ERROR` calls.

endoffile78 e667ec23b9 Replace make_quick_sort with qsort 2017-01-07 11:47:30 -06:00
iphydf e4d81e1520 Eliminate dead return statement.
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).

endoffile78 8899b69b40 Add DHT_create_packet 2016-11-11 15:53:04 -06:00
iphydf aed24408db Remove new_nonce function in favour of random_nonce.
`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.

iphydf 64870b6fd2 Move packing and unpacking DHT request packets to DHT module.
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.

iphydf 1977d56caa Remove return after no-return situation (and other cleanups).
Cleanups:
- Fix header guards to not use reserved names.
- Avoid name shadowing.
- Removed an unused variable found by avoiding name shadowing.

iphydf 15cb426166 Make toxcore code C++ compatible.
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.

iphydf 1494e474dd Ensure that all TODOs have an owner.
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.

iphydf 45d28904b9 Use <stdbool.h> and replace _Bool with bool.
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.

iphydf a8823830d3 Add some astyle options to make it do more.
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.

iphydf 0aa2840164 Group #include directives in 3-4 groups.
1. Current module (if C file).
2. Headers from current library.
3. Headers from other library (e.g. toxcore includes in toxav).
4. System headers.

iphydf ad26560516 Improve static and const correctness.
- 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.

Gregory Mullen (grayhatter) aad1e0ad3f Make friend requests stateless
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.

iphydf 13ae9e9a93 Move logging to a callback.
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.

iphydf db22522741 Add missing DHT_bootstrap to CMakeLists.txt.
- 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.
