* 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.
This allows invitations to work in the case that the invitee is already
in the group, which can happen if the group becomes split. Such an
invitation is automatically accepted, leading to the peers becoming
connected in the group and sharing peer lists.
The test's intermittent failure may well be exposing a real bug in the
TCP relay and/or onion systems, but we can't find the bug, and keeping
the test is disrupting our CI.
Also added and used the new crypto_malloc and crypto_free.
The latter also zeroes out the memory safely. The former only exists for
symmetry (static analysis can detect asymmetric usages).
We were mistakenly not making a rejoin attempt on freezing connections
due to all closest connections going down. This fixes that, and tweaks
the test. I've still only done tens rather than hundreds of tests, but
I'm fairly confident that the conference test now consistently passes.
* add freezing and unfreezing of peers
* add rejoin packet
* revise handling of temporary invited connections
* rename "peer kill" packet to "peer leave" packet
* test rejoining in conference test
* use custom clock in conference test
This forces all the loop bodies to be executed at least once, which is
harmless since it just means one more tox event loop iteration. This
reduces the jitter we see in coverage measurements, which is partially
caused by loops sometimes being entered and sometimes not (because their
condition happens to randomly already be true).
* specify correct source files
* add save_compatibility_test (commented out for now)
* reformat TESTS to one line per test, and set check_PROGRAMS := TESTS
* add run_auto_test.h to EXTRA_DIST
* Fix `AUTO_TEST_CFLAGS` -> `AUTOTEST_CFLAGS`.
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.
* test names in conference_test
* raise error on attempt to invite friend to group before we are connected
* revise handling of temporary invited connections
We are now careful not to prematurely delete a connection to a peer
established during the invitation process; namely, before we have sufficient
other connections and have confirmed that we have an alternative route to the
peer.
* process out-of-order messages from a peer
* don't reset names when handling a Peer Response
Renamed a poorly named test, fixed up a few printf statements,
substituted some unsigned integers with fixed size counterparts,
and implemmented the auto_run_test.h fixture for the lossy and
lossless packet tests.
The file_saving_test.c was not included in the cmake list
and thus was ignored by travis and "make check". I found this
out while introducing ck_assert_msg into the integration test.
Furthermore, removed some variable width integers from encryptsave_test.c,
and the SRunner utilization. Implemmented ck_assert_msg, reorganized some
loops, and removed some longs in file_transfer_test.c.
Did my best to surmise the size requirements of
these integers, will do the rest of the tests soon. Also added a todo
and made an obsessive change to a for loop.
* Moved PAIR to toxav, where it's used (but really this should die).
* Replace most MIN calls with typed `min_*` calls. Didn't replace the
ones where the desired semantics are unclear. Moved the MIN macro to
the one place where it's still used.
* Avoid assignments in `while` loops. Instead, factored out the loop body
into a separate `bool`-returning function.
* Use named types for callbacks (`_cb` types).
* Avoid assignments in `if` conditions.
* Removed `MAKE_REALLOC` and expanded its two calls. We can't have
templates in C, and this fake templating is ugly and hard to analyse
and debug (it expands on a single line).
* Moved epoll system include to the .c file, out of the .h file.
* Avoid assignments in expressions (`a = b = c;`).
* Avoid multiple declarators per struct member declaration.
* Fix naming inconsistencies.
* Replace `net_to_host` macro with function.
* Removed `ARRAY_SIZE` and use NULL markers for end of array, instead.
The alternative is + size, but for these arrays, NULL markers made
sense, since they are arrays of non-null pointers.
* Made `INDEX_OF_PK` a self-contained macro, not dependent upon the
naming inside its call site. This is a minor change but makes the code
more local and reviews easier.
* No nested structs.
* Use only named function types ending in `_cb` for callbacks.
* Replaced two macros with functions.
* `++i` instead of `i++`.
* struct member names start with lowercase letters.
* It takes a bit of work to support `/**/` comments in preprocessor
macros, so I've decided not to support these. If a macro is complex
enough to need comments inside it, it's too complex. `//` comments are
allowed at the end of macro definitions.
* Callback typedefs must name their parameters.
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
```
Also, renamed simple_conference_test to conference_simple_test so it's
sorted together with the other conference tests.
Next step is to use run_auto_test.h for the conference test.
Removed a pointless declaration of a function in lan_discovery_test
and cleaned up the one error message there. Did an entire restructuring
of the version_test using macros that resulted in fewer lines of code but more
thorough testing.
Formatting of version_test.c
back to old way, save comments and one change
Missing space
My greatest enemy
Add `#include <cstdio>` for `std::printf`.
Make tox.c unambiguously parseable.
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.

Use run_auto_test.h test fixture for some auto-tests.
Most of the auto-tests should use this fixture, but I've only done a few
to set an example.

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.
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.
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.
This triggers a code path in Persistent Group Chats that causes a memory
leak. I'm adding this test now, so that we don't merge PGC without fixing
the memory leak first.
This is needed for libvpx to work on android.
This also means that we can upload our test binaries to an android device
and actually run them, now that libcheck is no longer a blocker.
Also, add an auto-test for bootstrap and for LAN discovery.
Bootstrap is never tested otherwise, and LAN discovery is a prerequisite
for everything else. Having these two tests lets us rule out or identify
LAN discovery as a possible cause for test failures.
Also reduce number of people in conference to 5, because on Circle CI the
test times out trying to connect more than 6 or 7 people. The persistent
conferences PR will improve this so we can set it much higher then.
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.
Fixes#572.
As discussed in the issue, there's a risk that toxcore may not hold the
maximum bitrates libvpx supports, if toxcore insists on using integer
type. I initially proposed to have another flag in set(), so that we can
use unsigned type instead. iphydf came up with a better solution, that is
splitting the original functions, one for audio, one for video. Now, we
could safely replace int32_t with uint32_t.
Also: clean video_bit_rate_invalid()
Though this is not a part of issue #572, as it's used in the
toxav_bit_rate_set(), i cleaned the code. As mannol said, there should be
a check. Uint32_t is large enough to hold the maximum bitrates libvpx
supports, but user may pass a value larger than uint while smaller than
uint32_t. Thanks to the reminding from nurupo, it's no longer a stub
function.
Bitrate error enums are shared for both audio and video
https://github.com/TokTok/c-toxcore/pull/578#issuecomment-360095609, just
as iphydf said.
This way, developers compile toxcore, toxav, and toxencryptsave as C++ at
least once at home, reducing the likelyhood of running into travis
failures where we compile as C++ in the windows build.
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.
