ea36a453e3d06657679459e1168347648fa7c5c0 [net] Make p2p recv buffer timeout 20 minutes for all peers (John Newbery) Pull request description: The timeout interval for the send and recv buffers was changed from 90 minutes to 20 minutes in commit f1920e86 in 2013, except for peers that did not support the pong message (where the recv buffer timeout remained at 90 minutes). A few observations: - for peers that support BIP 31 (pong messages), this recv buffer timeout is almost redundant with the ping timeout. We send a ping message every two minutes, and set a timeout of twenty minutes to receive the pong response. If the recv buffer was really timing out, then the pong response would also time out. - BIP 31 is supported by all nodes of p2p version 60000 and higher, and has been in widespread use since 2013. I'd be very surprised if there are many nodes on the network that don't support pong messages. - The recv buffer timeout is not specified in any p2p BIP. We're free to set it at any value we want. - A peer that doesn't support BIP 31 and hasn't sent any message to us at all in 90 minutes is unlikely to be useful for us, and is more likely to be evicted AttemptToEvictConnection() since it'll have the worst possible ping time and isn't providing blocks/transactions. Therefore, we remove this check, and set the recv buffer timeout to 20 minutes for all peers. This removes the final p2p version dependent logic from the net layer, so all p2p version data can move into the net_processing layer. Alternative approaches: - Set the recv buffer timeout to 90 minutes for all peers. This almost wouldn't be a behaviour change at all (pre-BIP 31 peers would still have the same recv buffer timeout, and we can't ever reach a recv buffer timeout higher than 21 minutes for post-BIP31 peers, because the pong timeout would be hit first). - Stop supporting peers that don't support BIP 31. BIP 31 has been in use since 2012, and implementing it is trivial.

cd03513dc2fcccaa142e9632a28b38efd0056436 init: Signal-safe instant shutdown (Wladimir J. van der Laan) Pull request description: Replace the 200ms polling loop with a faster and more efficient waiting operation. This should speed up short RPC tests. This change has been tried a few times before, but abandoned every time because solutions used a condition variable which is not safe for use in signals, as they need to be reentrant. On UNIX-ish OSes, use a safe way: a pipe. When shutdown is requested write a dummy byte to the pipe. Waiting for shutdown is a matter of a blocking read from the pipe. On Windows, there are no signals so using a condition variable is safe. This only affects bitcoind. The GUI is unaffected by this change, and keeps polling as before in `BitcoinGUI::detectShutdown()`. It might be possible to listen to a pipe there, too, but I'm not sure, and it's complicated by the GUI-node abstraction.

This is fine when all the tasks eventually pass. Though for failing tasks, a failure should ideally be shown to the author and reviewer as soon as possible. Compute credits can be used to schedule immediately: https://cirrus-ci.org/pricing/#compute-credits. Running all tasks with compute credits will probably be more expensive than our previous CI invoice. However, they are also more flexible.

2020-12-15init: Signal-safe instant shutdownWladimir J. van der Laan
Replace the 200ms polling loop with a faster and more efficient waiting operation. This was tried a few times before, but given up every time because solutions use a condition variable which is not safe for use in signals as they need to be reentrant. On UNIX-ish OSes, use a safe way: a pipe. When shutdown is requested write a dummy byte to the pipe. Waiting for shutdown is a matter of a blocking read from the pipe. On Windows, there are no signals so using a condition variable is safe.

2020-12-14[net] Make p2p recv buffer timeout 20 minutes for all peersJohn Newbery
The timeout interval for the send and recv buffers was changed from 90 minutes to 20 minutes in commit f1920e86 in 2013, except for peers that did not support the pong message (where the recv buffer timeout remained at 90 minutes). A few observations: - for peers that support BIP 31 (pong messages), this recv buffer timeout is almost redundant with the ping timeout. We send a ping message every two minutes, and set a timeout of twenty minutes to receive the pong response. If the recv buffer was really timing out, then the pong response would also time out. - BIP 31 is supported by all nodes of p2p version 60000 and higher, and has been in widespread use since 2013. I'd be very surprised if there are many nodes on the network that don't support pong messages. - The recv buffer timeout is not specified in any p2p BIP. We're free to set it at any value we want. - A peer that doesn't support BIP 31 and hasn't sent any message to us at all in 90 minutes is unlikely to be useful for us, and is more likely to be evicted AttemptToEvictConnection() since it'll have the worst possible ping time and isn't providing blocks/transactions. Therefore, we remove this check, and sent the recv buffer timeout to 20 minutes for all peers. This removes the final p2p version dependent logic from the net layer, so all p2p version data can move into the net_processing layer. Alternative approaches: - Set the recv buffer timeout to 90 minutes for all peers. This almost wouldn't be a behaviour change at all (pre-BIP 31 peers would still have the same recv buffer timeout, and we can't ever reach a recv buffer timeout higher than 21 minutes for post-BIP31 peers, because the pong timeout would be hit first). - Stop supporting peers that don't support BIP 31. BIP 31 has been in use since 2012, and implementing it is trivial.

At that time, there was no function to determine whether the node was still in Initial Block Download, so to prevent syncing nodes from relaying old blocks to their peers, a check was added to never relay a block to a peer where the height was lower than 2000 less than the peer's best block. That check was updated several times in later commits to ensure that we weren't relaying blocks before the latest checkpoint if the peer didn't provide a startingheight. The checkpoint comparison was changed to compare with an estimate of the highest block in commit eae82d8e. In commit 202e0194, all block relay was gated on being out of Initial Block Download. In commit 0278fb5f, the comparison to nBlockEstimate was removed since "we already checked IsIBD()". We can remove the check against nStartingHeight entirely. If the node is out of Initial Block Download, then its tip height must have been within 24 hours of current time, so should not be more than ~144 blocks behind the most work tip. This simplifies moving block inventory state into the `Peer` object (#19829).
