Conner Fromknecht 3428fde5ab htlcswitch/link_test: batch preimage write test 2019-02-19 17:06:28 -08:00
Conner Fromknecht 76cecb1396 htlcswitch/link: batch write to preimage cache 
This commit makes use of the batched AddWitness
method of the WitnessCache, in order to avoid
performing one write for each accepted preimage.

Additionally, this fixes an existing hole in the
consistency guarantees since the batched writes
are now guaranteed to take place before accepting
the next CommitSig. Previously, these writes were
processed in an unsynchronized go routine that
could be delayed arbitrarily long before being
executed.

With this change, the async_payments_benchmarks
actually shows a slight improvement in
performance, presumably because we no longer do
an individual write per preimage, even though
the execution is now explicitly in the critical
path. There is likely also a marginal performance
improvement from the reduction in goroutine
overhead.

Conner Fromknecht 30f61b7630 multi: make AddPreimage variadic, optimistically compute key 
In this commit, we modify the WitnessCache's
AddPreimage method to accept a variadic number
of preimages. This enables callers to batch
preimage writes in performance critical areas
of the codebase, e.g. the htlcswitch.

Additionally, we lift the computation of the
witnesses' keys outside of the db transaction.
This saves us from having to do hashing inside
and blocking other callers, and limits extraneous
blocking at the call site.

Conner Fromknecht a00fc148c8 watchtower/wtclient/backup_task: make sweep pkscript independent of session 
This commit changes when the sweep pkscript
is assigned in the construction of the justice
transaction. Currently, the sweep pkscript is
assigned when the task is bound to a session.
However, we will moving to an assignment where
a unique sweep pkscript is used per channel to
prevent address inflation. Hence, this commit
makes the sweep pkscript a state dependent
variable, since it can be known at the time the
channel id is assigned.

Conner Fromknecht 2cf220a137 peer: handle message encoding errors on write 
In this commit, we modify the peer's writeMessage
method to properly handle errors returned from
encoding an lnwire message and from setting the
write deadline on the connection. Since an error
would likely result in an empty byte slice, the
worse case seems to be that we may have tried to
send an empty message on the wire.

Lastly, we correct the way we compute bytes sent
on the wire to properly count the number of bytes
*written*, and not just the length of the encoded
message.

This commit modifies the behavior of the

HTLCs.

The prior version returns true whenever
the link is found in the link index,
which may return true for pending
channels that are not actually active.

Conner Fromknecht eb2f5cecf6 multi: remove breach tx arg from NewBreachRetribution args 
This commit removes the breach transaction from the
arguments passed to NewBreachRetribution. We already
keep all prior remote commitments on disk in the
commitment log, and load that transaction from disk
inside the method. In practice, the one loaded from
disk will be the same one that is passed in by the
caller, so there should be no change in behavior
as we've already derived the appropriate state number.

This changes makes integration with the watchtower
client simpler, since we no longer need to acquire
the breaching commitment transaction to be able to
construct the BreachRetribution. This simplifies
not only the logic surrounding transient backsups,
but also on startup (and later, retroactively
backing up historic updates).
