This function exists and simplifies some code a little bit. There are
lots of places in DHT.c where we have the exact same code, so there is a
lot of opportunity to factor out common bits. For now, we just make a
minor improvement that's easy to review.
This may fix problems with very large conferences. Sadly, it seems
infeasible to test large conferences on one machine, so this is entirely
theoretical.
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.
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.
- Bump FreeBSD to 12.1.
- Simplify stage1 logic.
- Re-try downloading the image from a different mirror if one fails.
- Use the `expect` utility instead of dealing with screen's log file.
- Re-run failed toxcore test one more time and in sequence.
Put a future message number into the save file.
Peers require the message numbers of messages we send to increase
monotonically. If we save the current message number, then send further
messages, then quit without saving (e.g. due to a crash), and then
resume from the old save data, then monotonicity will fail. This commit
works around this problem by introducing an offset when the current
message number, so that even in the above circumstance, as long as fewer
messages than the offset were sent between saving and reloading, the
sent message numbers will increase monotonically.
The choice of offset is a balance between wanting it to be large enough
that there is room for plenty of messages to be sent in the above
scenario, and wanting to avoid the following potential problem: if we
repeatedly save and reload without sending any further messages, then
the message number may increase so far that peers will interpret an
eventual message as being old. This is not conceivably a practical issue
for the 32bit lossless message numbers, but is a concern for the 16bit
lossy message numbers.
- Moving a pthread_mutex in memory (e.g. via realloc()) is undefined
behavior.
- add a state for allocated but not yet used crypto connections
- change crypto_connection_status signature
