channeldb: add optional migration to prune revocation logs

2022-08-04 17:15:08 -07:00

Release Notes

Protocol Extensions

Add payment_addr flag to buildroute so that the mpp record of the route can be set correctly.
Hop hints are now opt in when using lncli addholdinvoice. Users now need to explicitly specify the --private flag.
Add chan_point flag to updatechanstatus and abandonchannel to offer a convenient way to specify the channel to be updated.
Add ignore_pair flag to queryroutes to allow a user to request that specific directional node pairs be ignored during the route search.

Delete failed payment attempts once payments are settled, unless specified with keep-failed-payment-attempts flag.
A new db configuration flag db.prune-revocation is introduced to take the advantage enabled by a recent space optimization. Users can set this flag to true to run an optional db migration during lnd's startup. This flag will prune the old revocation logs and save them using the new format that can save large amount of disk space. For a busy channel with millions of updates, this migration can take quite some time. The benchmark shows it takes roughly 70 seconds to finish a migration with 1 million logs. Of course the actual time taken can vary from machine to machine. Users can run the following benchmark test to get an accurate time it'll take for a channel with 1 millions updates to plan ahead,
```
cd ./channeldb/migration30
go test -bench=. -run=TestMigrateRevocationLogMemCap -benchtime=1000000x -timeout=10m -benchmem
```

Add previous_outpoints to GetTransactions RPC.
Fix P2TR support in ComputeInputScript.
Add wallet reserve RPC & field in wallet balance.
The RPC middleware interceptor now also allows requests to be replaced instead of just responses. In addition to that, errors returned from lnd can now also be intercepted and changed by the middleware.
The signrpc.SignMessage and signrpc.VerifyMessage now supports Schnorr signatures.
A new flag skip_temp_err is added to SendToRoute. Set it to true so the payment won't be failed unless a terminal error has occurred, which is useful for constructing MPP.
Add a message to the RPC MW registration flow so that the server can indicate to the client that it has completed the RPC MW registration.

An .editorconfig file was added to autoconfigure most text editors to respect the 80 character line length and to use 8 spaces as the tab size. Rules for Visual Studio Code were also added. And finally, the code formatting rules were extracted into their own document.
