Conflicts in src/libxrpl/telemetry/TelemetryConfig.cpp and its test:
phase-5's "require an https endpoint whenever use_tls=1" met phase-7's
version of the same guard, which already covers both the traces and the
metrics endpoint. Kept phase-7's side.
A transaction names one or more accounts: the sender in Account, and by
type a Destination, Owner, Issuer, Holder and so on. tx.process now
carries each top-level account-typed field as its own attribute, keyed
tx_<field> in lower snake case (tx_account, tx_destination, ...), so an
account can be searched for in traces whatever role it played.
Addresses are public ledger identifiers and are emitted raw.
The keys live in TxAccountSpanNames.h in libxrpl, with a field-to-key
table in TxAccountSpanNames.cpp. A library test walks TxFormats and the
SField registry: every account field a transaction can carry has a key,
and no field that only ledger entries carry has one. An empty account
field is skipped rather than rendered as the zero address.
An XRP account address is a public ledger identifier drawn from an
enumerable set. An unsalted hash of it is reversible by lookup, so it
protected nothing and only broke the join against explorers, RPC
responses and logs that show the same address.
- pathfind_source_account and pathfind_dest_account carry the request's
r-address. A value that does not parse as an r-address is not emitted,
so a malformed or mistaken request value never reaches a span. Both
handlers share setAccountAttribute() in PathFindSpanAttributes.h.
- pathfind_dest_currency is to_string(Asset): "XRP", "<issuer>/<CUR>",
or the MPT issuance id.
- The collector's attributes/hash processor is removed. No layer hashes.
- redactAccount() stays available; its header no longer claims to sit in
the emit path.
The Collector interface said instruments are created in the owning class's
constructor, but not why, or what the boundary is. onCollectionReady() runs
once, after every service the hooks read exists; a collector starts polling and
arms its observable instruments at that point. A gauge made after it is never
armed, so it is never exported, and nothing reports that.
Name the boundary on the interface, and the consequence on makeGauge(), the one
instrument where being late fails silently.
Three fixes in the telemetry wiring this branch owns.
An OTel collector records through the global meter provider, which only the
telemetry module installs. With [telemetry] enabled=0 the collector attached to
the SDK's noop provider, dropped every metric, and still logged that it had
started. makeCollectorManager now takes whether telemetry is on and warns; what
gets built is unchanged. telemetry_ is constructed before collectorManager_, so
the value is available.
The default metrics endpoint was spelled three times. Name it once as
kDefaultMetricsEndpoint, beside the export-cadence defaults that already live in
Telemetry.h for the same reason, and read it from the Setup member, the config
parser's default and the collector.
The scheme guard ran only when tls_client_cert was set, so use_tls=1 on an http
endpoint validated the certificate files and then exported in the clear. It now
covers every use_tls=1 node, for both signals. Two cases that pinned the old
behaviour are flipped to _throws, each asserting which endpoint key the message
names, and three more get https endpoints so the scheme guard is not what fires.
MonitoredMode::set calls onModeChange on every round start, so the span was
created whether or not the mode moved. A node with a steady mode therefore
emitted one mode_change per round carrying mode_old == mode_new, which a live
sweep confirmed on every round of both instrumented builds. The round span's
own consensus_mode attribute is still written on every call, since that is
where the round learns the mode it is running in.
accept.apply was a plain SpanGuard, so it never became the ambient span of
doAccept. The spans the function goes on to create inherited the activated
accept span instead and came out as accept.apply's siblings, while running
inside its own time window. Every guard was scoped before the SpanGuard split,
so this restores the hierarchy that design had.
Scoped now, so the hierarchy follows the call flow. Drops the parent-context
fallback arm with it: the accept context is captured only while the accept span
is live, and that span is a child of the round context, so an invalid accept
context implies an invalid round context and both arms returned an empty guard.
Only SpanGuard carried addEvent(name, attrs), so a call site holding a scoped
guard could not record an event attribute. Forwarding overload, with the no-op
twin in the telemetry-disabled stub, so a span can be converted between scoped
and unscoped without dropping the attributes on its events.
The C-string overload of setAttribute handed its pointer straight to
std::string_view, whose pointer constructor reads the pointer to find the
length. A null one is undefined behaviour.
A null pointer carries no text, and an empty value already means something on
this class, so nothing is recorded rather than an empty string.
The overload itself has to stay. Without it a string literal would bind to the
bool overload, because pointer-to-bool is a standard conversion and beats the
string_view one, so every string attribute would silently record true. The
header now records that.
Resolved src/libxrpl/tx/applySteps.cpp. calculateBaseFee now returns
std::expected<XRPAmount, TER>, so invokePreclaim rejects the transaction when
the fee cannot be computed. Kept that inside this branch's preclaimTer wrapper,
so the returned error also reaches the span's ter_result attribute.
