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.
Two conflicts, both resolved by composing the sides rather than taking one.
cfg/xrpld-example.cfg: this branch had moved the batch-processor keys under
their own heading while upstream edited them in place, so a merge-both would
have documented them twice. Upstream's range sentences are applied to the
relocated block and the head-sampling note keeps its position.
02-design-decisions.md: the summary table changed on both sides for different
reasons. Upstream renamed ledger_index to current_ledger_seq and ledger_seq;
this branch had corrected the PathFinding row to the keys it actually emits.
Both are kept.
childSpan() takes the span name verbatim, so a bare op:: suffix names the span
"process" rather than "rpc.process". The same defect was corrected in the
SpanGuard and Telemetry examples; this is the last copy.
Span kind was derived from TraceCategory alone, so every Rpc-category span was
kServer. A category cannot tell an inbound handler from the internal work under
it, and trace backends pair kServer with kClient, so internal spans left as
kServer become unpaired edges in a service graph and read as extra inbound
requests.
SpanRole is a new xrpl-owned enum, orthogonal to TraceCategory: the category
names the subsystem and gates the span on config, the role says whether the span
handles a remote call. It is a defaulted fourth parameter on span(), freshRoot()
and the ScopedSpanGuard equivalents, defaulting to SpanRole::FromCategory, so no
existing call site changes. resolveSpanKind() applies an explicit role and falls
back to the category map, which keeps its single responsibility. The
telemetry-disabled stubs mirror all four signatures.
No call site passes a role yet. The two that need it are on a later branch.
Also fixes a ScopedSpanGuard example that passed a bare op:: suffix to
childSpan(), which takes the name verbatim. Naming the child rpc.command made it
a child of rpc.command.<cmd>, inverting the hierarchy, so the example's parent is
now rpc.process and the command attribute moved onto the command span.
Review feedback on the RPC integration PR.
The childSpan examples could not work as written. childSpan() takes its parent
from the ambient context and uses impl_ only as a liveness gate, so an unscoped
SpanGuard parent produced two siblings rather than a parent and child. The parent
is now a ScopedSpanGuard, the child no longer reuses the parent's name, and the
examples pass a full dotted constant because childSpan() takes the name verbatim.
Five of the ten Rule D tests could not fail. Four passed an empty L1 key set,
which makes the rule skip validation altogether; the fifth asserted an empty
result against an escaped-quote selector that extracted no labels at all. Each
now passes a nonempty L1 set and carries a known-bad label in the same
expression, so it asserts both that the intended labels are accepted and that
Rule D ran. Verified by disabling the rule: the old tests stay green, the new
ones all fail.
Span kind is not fixed here. categoryToSpanKind and the span factories belong to
the telemetry library, so the role parameter is routed to that branch, and the
two call sites here follow once it exists.
[telemetry] endpoint carried one OTLP signal while its name implied it
covered every signal. That asymmetry is what let the metrics URL be
guessed later by rewriting this one's path suffix, so anything not
ending /v1/traces silently posted metrics to the traces path.
Renames the key to traces_endpoint and Setup::exporterEndpoint to
tracesEndpoint. The default value is unchanged and the URL is still used
verbatim, with no path derived from it. The startup log line and the
compose-file example name the new key, the latter being where an
operator copies it from.
No metrics_endpoint is added here: this branch has no metrics pipeline,
so the key would parse into a member nothing reads.
getInstance(), getTracer(), both startSpan() overloads and networkTypeFromId()
return values that a caller must use. A discarded startSpan() result destroys
the returned span immediately, so the span opens and closes with no content.
Six methods in Telemetry.h already carried the attribute, on the base and on
every override. The new attributes follow that: the overrides in Telemetry.cpp
and NullTelemetry.cpp get it too, because [[nodiscard]] is not inherited and a
call bound to the derived type would otherwise be unchecked.
No caller anywhere in the chain discards any of these results.
The default setServiceInstanceId() body ignores its argument. Use the
attribute rather than a (void) cast: the codebase already uses it 104 times
and the build is C++23.
