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.

Also, avoid the need for putting `_XOPEN_SOURCE` in every test file.

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
```

Mostly documentation + comments. Some cases where code was removed
in exchange for more compact/less sprawly for loops. Introduced a
function that removed like 30 lines of repeated code.
|
|
This one has ASAN enabled, unlike Travis.
|
|
The C compiler warns because the value is initialised in a loop and used
outside of it. In this case, it's always initialised, but changing the
value of `NUM_PORTS` can change that.
|
|
Better error messages, better sleep() call placements, etc.
Did not modify large chunk of function because I couldn't explain
it. Maybe I'll come back later once I've regained lost brain cells.
|
|
Tests all ports instead of just one, also adds some comments/changes
error messages to be more descriptive
|
|
The Family stuff in toxcore is a big mess. I'm sure I saw a bunch of bugs
on the way, but I'm not verifying that code now, so the bugs stay.
|
|
|
|
We control the random functions in crypto_core, so we can make them
deterministic more easily. This will help test reproducibility in the
future.
|

|
This changes only code, no string literals or comments.
|
|
Also some missing return value checks for `fopen`.

Tests are not actually ran on appveyor for now, since they all fault for
some reason. For now, we just build them. Also, some tests are disabled
on msvc entirely, because they don't even compile. We'll need to look
into those, later. They are disabled using `MSVC_DONT_BUILD`.
|
|
Also fix a mistake with forgotten braces around parameter
|

socket -> net_socket
htons -> net_htons
htonl -> net_htonl
connect -> net_connect
sendto -> net_sendto_ip4
getaddrinfo -> net_getipport
sa_family_t -> Family

This reverts commit 59e2a844f04a8725e8079f854158aa86ef5988b2, and
defines _DARWIN_C_SOURCE in toxcore/network.c

This reverts commit f3469070fe899e8e4fd88665386a55bad9f77cd8.

- CFLAG gnu99 was changed to c99.
- CXXFLAG c++98 was changed to c++11.
- CFLAG -pedantic-errors was added so that non-ISO C now throws errors.
- _XOPEN_SOURCE feature test macro added and set to 600 to expose SUSv3
and c99 definitions in modules that required them.
- Fixed tests (and bootstrap daemon logging) that were failing due to
the altered build flags.
- Avoid string suffix misinterpretation; explicit narrowing conversion.
- Misc. additions to .gitignore to make sure build artifacts don't wind
up in version control.

`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.

Compiling as C++ changes nothing semantically, but ensures that we don't
break C++ compatibility while also retaining C compatibility.
C++ compatibility is useful for tooling and additional diagnostics and
analyses.
|
|
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.
|
|
- All global variables should be static unless they have an explicit
extern declaration in a header file.
- `to_compare` was not used in encryptsave and toxav tests.
- `break` in switch cases is not required directly after `return`,
`goto`, or a noreturn function like `abort`.
|
|
|
|
We should aim to make as many structures module-private as possible.
|
|
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.
|
|
- 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.
|

- Don't cast between object and function pointers.
- Use standard compliant `__VA_ARGS__` in macros.
- Add explicit `__extension__` on unnamed union in struct (it's a GNU
extension).
- Remove ; after function definitions.
- Replace `const T foo = 3;` for integral types `T` with `enum { foo = 3 };`.
Folding integral constants like that as compile time constants is a GNU
extension. Arrays allocated with `foo` as dimension are VLAs on strictly
compliant C99 compilers.
- Replace empty initialiser list `{}` with zero-initialiser-list `{0}`.
The former is a GNU extension meaning the latter.
- Cast `T*` (where `T != void`) to `void *` in format arguments. While any
object pointer can be implicitly converted to and from `void *`, this
conversion does not happen in variadic function calls.
- Replace arithmetic on `void *` with arithmetic on `char *`. The former
is non-compliant.
- Replace non-`int`-derived types (like `uint16_t`, which is
`short`-derived) in bit fields with `int`-derived types. Using any type
other than `int` or `unsigned int` (or any of their aliases) in bit
fields is a GNU extension.

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.

The expression was fun(foo = bar, foo). The evaluation order is unspecified,
and often this will do the wrong thing. We should forbid side effects in
argument lists and conditionals.

See #27 and #40 for details.

fix: make increment_nonce & increment_nonce_number independent of user-controlled input
fix: make crypto_core more stable agains null ptr dereference
