This commit modifies the client's filtering when selecting from existing
sessions. The new logic compares the configured TxPolicy with the
TxPolicy of the candidate sessions, which has the effect of ignoring
operational parameters such as MaxUpdates. Prior, changing MaxUpdates
would cause the client to request a new session even if it had perfectly
good slots available in a policy with an equal TxPolicy.
This commit splits out the parameters that shape the justice transaction
into their own struct, which then embedded within the overarching
wtpolicy.Policy which may have additional parameters describing
operation of the session.
This is done as a preliminary step to support comparison of sessions
based on matching TxPolicy configurations. This prevents otherwise
identical Policies from being counted as different if operational
parameters like MaxUpdates differ, even if it has no material difference
to the justice transaction.
This commit fixes a bug that would cause us to request more sessions
that needed from the session negotiator. With the current stat ticker,
we'd ask the negotiator for a new session every 30s if session
session negotiation did not return before printing the stats. Now we'll
avoid requesting to sessions by jumping back into the select loop.
This commit moves the newSweepPkScript function
previously in the nursery to be a helper function
within the server. Additionally, the function now
returns a closure that satisfies the configuration
interfaces of several other subsystems.
As a result, the configuration sites contain much
less boilerplate, as it's now encapsulated in
the newSweepPkScriptGen helper.
In this commit, we patch a small bug in the newly added raw tx hex field
for ListTransactions. We now ensure that we also set the raw tx hex
field for unconfirmed transactions.
Since nilling the pubkey curve will lead to a nil-pointer exception if
the key is later used for signature verification, we make sure to make a
copy before nilling and spewing.
