Cimple cannot actually find these without also causing false positives,
but I found them with cimple before removing the code causing false
positives again.
These were found by the new stronger type check in cimple. The one
bugfix is in `crypto_sha512_cmp`, which used to think `crypto_verify_32`
returns bool while actually it's -1/0/1.
Use of `strcpy` in these particular cases was safe, but it's hard to
tell and also useless. `strcpy` would effectively need to do another
`strlen` which we already did.
Also removed sprintf, which was also safe in this case but it's easier to
be "obviously safe", especially for static analysers.
These have all dependencies built with asan/tsan, so they can do deeper
sanity checks such as checking what opus is doing with our buffers.
The asan check currently fails for me locally, so these are not yet set
to be required for PRs to be merged.
atoi doesn't check if the conversion from string to int succeeded
which doesn't allow us to do proper error handling.
We also now make sure that the port argument is a valid port
in addition to being properly converted
This seems to be the sweet spot for the current tokstyle implementation.
4 cores gives the same speedup, 5 also, 6 makes it slower, and 2 also
makes it slower.
This aligns the autotools build with the cmake build, which doesn't have
a config.h file. It also removes the ambiguity of config.h and
other/bootstrap_daemon/src/config.h.
This doesn't currently work, because we get a lot of errors during tests.
This should not happen. Either those errors are warnings, or something is
wrong with either the code or the test.
This check puts all of our code in a C++ anonymous namespace, which is
effectively making all functions `static`. This allows the compiler to
determine that a function is unused, so we can delete it.
It is invalid to compile an XPG3, XPG4, XPG4v2, or XPG5 application
using c99. The same is true for POSIX.1-1990, POSIX.2-1992, POSIX.1b,
and POSIX.1c applications. Likewise, it is invalid to compile an XPG6
or a POSIX.1-2001 application with anything other than a c99 or later
compiler. Therefore, Solaris libc forces an error in both cases.
Reduced by, e.g.:
* `file_transfer_test`: 33% of the `clock_gettime` calls.
* `tox_many_test`: 53% of the `clock_gettime` calls.
Other tests will see similar improvements. Real world applications will
be closer to 40-50% improvement, since tox_many_test has 100 nodes, while
file_transfer_test has 2 nodes.
It turns out, `unix_time` is also monotonic, and is used as such, so I've
renamed the new functions to `mono_time_*`.

```
00:01 <@irungentoo> the idea used to be that the unix_time() function
could go backward in time but I think I might have started using it like
if it could not after I changed it so that it would never go back in time
```
Rules:
1. Constants are uppercase names: THE_CONSTANT.
2. SUE[1] types start with an uppercase letter and have at least one
lowercase letter in it: The_Type, THE_Type.
3. Function types end in "_cb": tox_friend_connection_cb.
4. Variable and function names are all lowercase: the_function.
This makes it easier for humans reading the code to determine what an
identifier means. I'm not convinced by the enum type name change, but I
don't know a better rule. Currently, a lot of enum types are spelled like
constants, which is confusing.
[1] struct/union/enum
These display some idea, but the tests are not implemented correctly. We
will need to implement the idea correctly later, but for now we can't use
these.
This change does not include the addition of VP9. We do that in a
separate pull request.
Changes:
* fix the video bug (video frames larger than 65KBytes) by sending full
frame length in alternate header field
* improve video frame reconstruction logic with slots
* configure video encoder and decoder to be multihtreaded
* set error resilience flags on video codec
* change encoder and decoder softdeadline
follow TokTok#731. This commit
completely removed all things in namespace bit_rate, and deprecated
functions are to be added back in another commit. set_xxx() is treadted
as a property of namespace audio&video, same as bit_rate change event.
toxav_basic_test is fixed, either.
Also got rid of two VLAs. They are overused a bit in toxcore. In
irc_syncbot, the array was uninitialised and then filled by a recv system
call. This can cause uninitialised reads if recv doesn't fill the entire
array. It could not cause out of bounds read directly, because a
NUL-terminator was in place, but both cases are undefined behaviour.
This allows us and users to reproducibly build verified versions of the
library with checksums. It will power the toktok-stack continuous build
with checked-in checksums at specific git revisions.
This isn't adding value. We're going to redo the whole rpc test framework
in the future, after a lot of refactoring that the hstox test currently
just stands in the way of.
