Correctly update the last block hash on disconnect

When a block is disconnected, the hash of the disconnected block was

no-op because these hashes should be equal. Successive disconnections

Normally, this not a problem because the last block_disconnected should

re-org. However, this assumes the user calls the API correctly and that
no failure occurs that would prevent block_connected from being called

3 years agoProcess monitor update events in block_[dis]connected asynchronously
Matt Corallo [Fri, 26 Feb 2021 17:02:11 +0000 (12:02 -0500)]
Process monitor update events in block_[dis]connected asynchronously

The instructions for `ChannelManagerReadArgs` indicate that you need
to connect blocks on a newly-deserialized `ChannelManager` in a
separate pass from the newly-deserialized `ChannelMontiors` as the
`ChannelManager` assumes the ability to update the monitors during
block [dis]connected events, saying that users need to:
```
4) Reconnect blocks on your ChannelMonitors
5) Move the ChannelMonitors into your local chain::Watch.
6) Disconnect/connect blocks on the ChannelManager.
```

This is fine for `ChannelManager`'s purpose, but is very awkward
for users. Notably, our new `lightning-block-sync` implemented
on-load reconnection in the most obvious (and performant) way -
connecting the blocks all at once, violating the
`ChannelManagerReadArgs` API.

Luckily, the events in question really don't need to be processed
with the same urgency as most channel monitor updates. The only two
monitor updates which can occur in block_[dis]connected is either
a) in block_connected, we identify a now-confirmed commitment
   transaction, closing one of our channels, or
b) in block_disconnected, the funding transaction is reorganized
   out of the chain, making our channel no longer funded.
In the case of (a), sending a monitor update which broadcasts a
conflicting holder commitment transaction is far from
time-critical, though we should still ensure we do it. In the case
of (b), we should try to broadcast our holder commitment transaction
when we can, but within a few minutes is fine on the scale of
block mining anyway.

Note that in both cases cannot simply move the logic to
ChannelMonitor::block[dis]_connected, as this could result in us
broadcasting a commitment transaction from ChannelMonitor, then
revoking the now-broadcasted state, and only then receiving the
block_[dis]connected event in the ChannelManager.

Thus, we move both events into an internal invent queue and process
them in timer_chan_freshness_every_min().
