- 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
* unset global status callback in kill_groupchats
* avoid dangling friend connections
* fix num_introducer_connections leak
* stop trying to keep connection alive on freeze
* avoid relaying lossless messages back to sender where possible
* avoid sending gratuitous online packets
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.
