The default stack size for musl-libc is 128kb. Therefore we should try to keep stack
allocations well below this limit in order to avoid stack overflows.
* Use-after-free because we free network before dht in one case.
* Various unchecked allocs in tests (not so important).
* We used to not check whether ping arrays were actually allocated in DHT.
* `ping_kill` and `ping_array_kill` used to crash when passing NULL.
Also:
* Added an assert in all public API functions to ensure tox isn't NULL.
The error message you get from that is a bit nicer than "Segmentation
fault" when clients (or our tests) do things wrong.
* Decreased the sleep time in iterate_all_wait from 20ms to 5ms.
Everything seems to still work with 5ms, and this greatly decreases
the amount of time spent per test run, making oomer run much faster.
We put some tokstyle exemptions into the source files themselves,
instead. This way we can check some of the code in those files, and more
in the future when tokstyle supports more constructs (like apidsl).
Also: hacked ping_array.api.h to not emit `_array` as parameter names.
We'll need to fix apidsl to do this better. This works for now.
https://github.com/TokTok/hs-tokstyle/pull/43 implements a validation for
this. We should avoid locally declaring functions from another
translation unit, and instead use header files to export/import them.
* make static functions return bool rather than int to indicate success
* add peer_in_list() to factor out uniformity over peer and frozen lists
* reduce repetition in send_lossy_all_close
* rename 'close' to 'connections'
* use uint32_t for peernumber (in accord with tox.c)
* explain persistence in tox_conference_get_chatlist documentation
* clarify "connectedness" in group API documentation
* clarify that tox_conference_peer_count counts only online peers
* refactor variously
In windows network code, we implement inet_pton and inet_ntop, which take
void pointers. We can do slightly better because we already know the type
when we call these functions, so we can avoid casting between void
pointer and the addr struct types.
Tokstyle (check-cimple) will start enforcing comment formats at some
point. It will not support arbitrary stuff in comments, and will parse
them. The result can then be semantically analysed.
* Use Camel_Snake_Case for type names.
* Use at least 4 characters for constant names. I.e. `END` is a type
name, but `RETURN` is a constant name. This is because `DHT` is a type
name (yay consistency).
* Using `min_*` functions instead of MIN, we can avoid a cast.
* Use `for`-loops for for-each-frame semantics instead of `while`.
* Don't use assignments as expressions.
* `++i` instead of `i++`.
* Function pointers are dereferenced automatically, so no need to
manually do so.
* Avoid void pointers that lie about not being spaghetti code. Toxcore
and toxav are both spaghetti and shouldn't pretend anything else.
* Don't use empty statements (e.g. no `;;` anywhere in the code).
