We have a more portable wrapper that is now also thread-safe. Also
stopped using sprintf in the one place we used it. This doesn't really
help much, but it allows us to forbid sprintf globally.
Also added a valgrind build to run it on every pull request. I've had to
disable a few tests because valgrind makes those run infinitely slowly,
consistently timing them out.
Tokstyle no longer allows:
* Includes inside an `extern "C"`
* Comments on function definition and declaration to be different.
* Doxygen comments commenting on other doxygen comments.
* `crypto_memcmp` was replaced by more specific functions. We never want
to compare arbitrary amounts of data this way. We use these functions
to compare key material.
* apidsl has been bothering people, so now we un-bother them. You're
welcome.
* Added the memlock/unlock functions from the New Group Chats branch.
* Remove some system dependencies in crypto_core_mem.c.
* Renamed UPPERCASE_NAMES to Snake_Camel_Case names.
Currently only `crypto_core_mem.c` needs this. We should try not to
depend on configure'd values. Also note: config.h is only created and
used in the autotools build. In CMake, we pass `-D` flags directly.
The android warnings are disabled now because they suggest using
linux-only extensions of libc. Useful for android indeed, but we're
targeting non-android and non-linux systems as well.
All for-loops must have an init-decl, a condition, and an increment
statement. Any loop that doesn't have one of these should be a while
loop (only 2 of these exist in toxav, none in toxcore).
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.
