resolveNodePublicKey() returned std::nullopt in three real cases: a first boot
with no wallet database, a standalone run (its wallet is a private temporary
database), and --newnodeid. Telemetry's resources are built during
ApplicationImp's member-init list and are immutable, so on those runs the node
reported an empty service.instance.id and no xrpl.node.id for the whole run,
while setup() minted a key moments later and patched only the tracer.
Replace it with resolveNodeIdentity(), which always returns a keypair: derived
from a configured seed, else read from an existing wallet database, else
minted. Main.cpp passes that pair to makeApplication(), ApplicationImp stores
it in nodeIdentity_ -- now declared before telemetry_ and no longer an optional,
because it is always set -- and builds the telemetry resource from it.
setup() calls getNodeIdentity(), which now persists rather than mints: it
stores the resolved pair when the wallet holds no identity, adopts the stored
one when it does, and clears first for --newnodeid. The write stays in setup()
because that is where the database exists; a standalone run has no persistent
wallet to write to, which is why the pair has to be decided before
construction rather than read back afterwards. Wallet gains storeNodeIdentity()
for that write, and getNodeIdentity(session) now uses it instead of repeating
the insert.
The three-argument makeApplication() mints a keypair, so jtx::Env and any other
test Application behave as a standalone run always did.
Also fold the three hand-rolled "meter from a NoopMeterProvider" copies into
telemetry::noopMeter(): the base-pointer call and the kMeterVersion argument are
both easy to get wrong alone, and the meter identity has to match the one the
histogram views select on.
The new gtest covers the wallet half: store-then-read, store not replacing an
existing identity, clear-then-store, and that the mint path persists. It adds
the tests.libxrpl > xrpl.rdb levelization edge, regenerated here.
beast::insight instruments are created during ApplicationImp's member-init
list, and opentelemetry-cpp 1.28 never rebinds an already-vended Meter, so an
instrument created before the MeterProvider is published records nothing for
the rest of the process. Observable instruments carry the opposite constraint:
registering one arms the SDK reader thread, and its callbacks run hook handlers
that read services which do not exist that early.
Publish the provider in Telemetry's constructor, ahead of every producer, and
defer only the observables. Collector gains onCollectionReady() and
onCollectionStopping(); OTelCollector arms and disarms its gauges in response.
StatsDCollector starts its polling thread in its own constructor and had the
same hazard, so it uses the pair to gate that thread.
The metrics resource carries service.instance.id and is immutable once built,
so the node public key is resolved in Main.cpp, where a config error can still
be reported, and passed to makeApplication(). getNodeIdentity() remains
authoritative; both paths now share readNodeIdentity(), so telemetry cannot
report a key the node has abandoned.
An explicit ~ApplicationImp stops observing and stops telemetry, covering the
setup() failure paths that never reach run(). Telemetry::stop() is once-only
and no longer clears another instance's global pointer. The histogram view's
meter selector now matches the meter actually in use, so its bucket boundaries
apply for the first time.
This change modularizes the `WalletDB` and `Manifest`. Note that the wallet db has nothing to do with account wallets and it stores node configuration, which is why it depends on the manifest code.
