Phase-10 brought in the upstream nodestore/peerfinder/consensus reorganisation
along with its own write-path telemetry, which collided with the sync-diagnostic
signals on this branch. Twelve files conflicted; every resolution keeps both
intents rather than picking a side.
The nodestore write timing was implemented twice, independently. Both sides
added getStoreDurationUs()/getFetchDurationUs() to Database and both timed the
backend call in each concrete store(). Keeping both would have added twice to
storeDurationUs_ per store while storeStats() still counted one, so the mean
write latency would have read double on every dashboard -- silently, since no
test on either side asserts an exact microsecond figure. Resolved to one
accumulator API: recordStoreDuration(), which takes a duration, clamps a
sub-microsecond sample to zero and uses a relaxed atomic add. Phase-10's
storeDurationStats() is gone and its two call sites now use the survivor, so
all three store paths -- both store() overrides and importInternal() -- add
exactly once.
SlotCensus and its pure virtual moved from src/xrpld/peerfinder/ to
include/xrpl/peerfinder/PeerfinderManager.h, following the Manager interface
upstream relocated. The xrpld header is now phase-10's makeConfig shim, and
Overlay.h, MetricMacros.cpp and the getSlotCensus() override chain point at the
new location. ConsensusSpanNames.h and peerfinder Slot.h/Config.h include paths
followed their headers into libxrpl the same way.
InboundLedger gained phase-10's AcquireStats counters next to this branch's
span activations in both the destructor abort path and done(); neither
displaces the other. nodestore_state keeps the constant-based name this branch
requires of it and phase-10's fuller description.
Upstream #7292 deleted src/test/nodestore/Database_test.cpp, which held this
branch's testDurationAccessors. Phase-10 restored the per-store half of that
coverage in DatabaseConfig_test, but nothing covered importInternal -- it writes
through storeBatch() and never through store(), so it is a third store path that
has to time itself. That half is ported to a GTest in
src/tests/libxrpl/nodestore/Database.cpp, keeping the exact zero-before and
accumulate-after assertions and the per-instance negative check.

Two suspects from the 3.3.0 slowdown investigation had no signal. Both were
already computing the numbers and throwing them away, so this exposes them
rather than adding measurement.
Per-sweep heap trim. The trim runs after every cache sweep, and its cost
scales with resident heap, so it is the leading explanation for a node with
a populated database syncing slower than a fresh one. The report already
carried duration, fault deltas and reclaimed pages, but the whole
measurement sat behind a debug-journal check, so an ordinary node measured
nothing, and the call site discarded the result. The measurement now always
runs and only the log line stays gated. Records trim duration, minor faults
and reclaimed kilobytes. Measured cost of the always-on path is about six
microseconds per sweep against a trim costing milliseconds, at a cadence of
ten to a hundred and twenty seconds.
Honest limit, stated in the runbook: the fault delta spans only the trim
call, so it shows the trim itself faulting but not the faults that follow as
caches refill. The duration is the signal to correlate against sweep-job
queueing.
Rotation writes. Rotation copies archive-served reads forward and re-stores
nodes missing from both backends, both of which compete with sync I/O and
only happen on a populated online_delete database. The copy-forward count
existed but was reset by the rotation's own log line, so a metric reading it
would drop to zero on every swap; a never-reset total sits beside it now.
The re-store count was not measured at all. Rotation duration is
deliberately not recorded: the health throttle sleeps at eight points inside
the sequence and dominates exactly when the node is unhealthy, so the number
would conflate work with waiting.
Nothing added for the other two suspects. Get-object serving is already
covered by the handler label, the lookup histogram and the deferred and
saturation gauges; peer churn by the disconnect-reason counter.
Also replaces nine per-file cspell ignores with one ignoreRegExpList entry
for the telemetry macro names, and picks up the levelization baseline for the
consensus span-name test.

This change renames all occurrences of `namespace ripple` and `ripple::` to `namespace xrpl` and `xrpl::`, respectively, as well as the names of test suites. It also provides a script to allow developers to replicate the changes in their local branch or fork to avoid conflicts.
Per XLS-0095, we are taking steps to rename ripple(d) to xrpl(d).
This change specifically removes all copyright notices referencing Ripple, XRPLF, and certain affiliated contributors upon mutual agreement, so the notice in the LICENSE.md file applies throughout. Copyright notices referencing external contributions remain as-is. Duplicate verbiage is also removed.
Per XLS-0095, we are taking steps to rename ripple(d) to xrpl(d).
C++ include guards are used to prevent the contents of a header file from being included multiple times in a single compilation unit. This change renames all `RIPPLE_` and `RIPPLED_` definitions, primarily include guards, to `XRPL_`. It also provides a script to allow developers to replicate the changes in their local branch or fork to avoid conflicts.
