Move the per-RPC trace log line up to fire on the terminal (region
drained, range == nil) branch as well as the non-terminal paging path
that was already covered. Add a 'terminal' boolean so offline analysis
can distinguish the two:
- terminal=false → non-terminal paging RPC (region not yet drained).
Same population as the EMA training set below.
Whether each such RPC was capped by rows, time, or
bytes depends on tidb_paging_size_bytes — the log
does not care.
- terminal=true → TiKV's executor drained the region (scenario A
natural tail of a large region; scenario B a small
region scanned in one RPC). Previously not logged
at all, which left a >50%% sample blind spot vs PD's
paging_prediction_residual_bytes histogram.
The terminal signal is purely 'region drained', not 'byte budget hit',
so this fix applies uniformly to all paging modes including
tidb_paging_size_bytes=0 (rows/time-driven paging).
The region/lock retry path is intentionally still NOT logged: predicted
vs actual aren't comparable on a retry, and emitting them would only
muddy residual analysis.
The EMA Observe site stays where it is. Only non-terminal paging RPCs
feed the predictor, since they are the only sample class whose 'next of
the same kind' is well-defined within a (iter, region) sequence.
Including terminal samples in the EMA would pull predictions below the
typical mid-region size, under-charging the next non-terminal RPC at
pre-charge time and weakening tier protection.
Net effect: the log row set becomes a strict superset of the EMA
training set, with the EMA-comparable subset recoverable by filtering
terminal=false. This closes the observability blind spot (R7 follow-up
pingcap#2) where Grafana's PD-side residual histogram saw p50 ~= -14 MiB while
log analysis saw p50 ~= 0, the gap being entirely unlogged terminal
RPCs.

EXPLAIN showed p2023_s0 for a 2024 date range query because PartitionPruning for RANGE+shard tables only did shard-slot pruning (all logical partitions survive) and returned flat index 0 (p2023_s0) when slot 0 matched. Fix: add pruneShardedRangeDynamic (dynamic mode) and processShardedRangePartition (static mode) — both perform two-stage pruning: 1. RANGE pruning on logical partitions via pruneRangePartition + original PI 2. Shard-slot pruning via pruneShardKeyPartition on flat PI 3. Intersect: surviving flat indices = partIdx*shardCnt + slot With this fix, EXPLAIN for `WHERE created_at BETWEEN 2024... AND company_id=42` correctly shows only p2024_s0 (or whichever slot company_id hashes to). Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Fixes for D3Hunter's review on pingcap#68028: [Blocker] Dual-password clauses are parsed but ignored by execution - Add executor stubs that reject RETAIN CURRENT PASSWORD / DISCARD OLD PASSWORD with ER_NOT_SUPPORTED_YET in executeAlterUser and executeSetPwd. Full execution / privilege / storage logic lives in the follow-up PR pingcap#68393. - Expose exeerrors.ErrNotSupportedYet for callers (was previously only available via dbterror.ClassExecutor.NewStd inline). - New TestDualPasswordParserOnlyStub in passwordtest to pin the stub's behavior. [Major pingcap#2] CREATE USER accepted dual-password clauses outside MySQL grammar - Drop the CreateUserSpec/CreateUserSpecList non-terminals and route CREATE USER back through the original UserSpec/UserSpecList chain. CREATE USER + RETAIN/DISCARD is now a parser-level syntax error, matching MySQL. [Major pingcap#3] ALTER USER over-accepted invalid RETAIN combinations - Introduce AuthOptionWithPassword (the BY-form subset of AuthOption) and restructure AlterUserSpec to bind RETAIN only to that subset. Reject at parse time: ALTER USER u IDENTIFIED WITH plugin AS '<hash>' RETAIN ... ALTER USER u IDENTIFIED WITH plugin RETAIN ... ALTER USER u RETAIN CURRENT PASSWORD (no auth) ALTER USER u IDENTIFIED BY '...' DISCARD OLD PASSWORD - DISCARD becomes its own AlterUserSpec variant (no auth-option coexists with it). [Major pingcap#4] Grammar label/documentation contradiction - Drop the misleading 'unsupported dual password option' label on the deleted CreateUserSpec; rewrite UserSpec/AlterUserSpec labels to state the contract accurately. [Major pingcap#5] Generic *PasswordOrLockOption type was overloaded - Introduce dedicated ast.DualPasswordOption and ast.DualPasswordOptionType (with DualPasswordRetainCurrent / DualPasswordDiscardOld). UserSpec.DualPasswordOption now uses the dedicated type. Remove the RetainCurrentPassword and DiscardOldPassword iota entries from PasswordOrLockOption. [Minor pingcap#6] ALTER USER USER() branch - USER() still does not route through AlterUserSpecList; dual-password on USER() is now a parse-time syntax error (covered by negative test). [Minor pingcap#7] Parser tests had no negative coverage - Add explicit ok=false rows for CREATE USER + RETAIN, the AS-hash + RETAIN form, bare RETAIN with no auth, plain BY + DISCARD, bare-plugin + RETAIN, and ALTER USER USER() + RETAIN. [Minor pingcap#8] CREATE/ALTER user-spec grammar duplication - Now naturally eliminated because CREATE USER reuses UserSpec. Behavior PR (pingcap#68393) needs to: - Remove the executor stubs added here. - Adopt the new ast.DualPasswordOption / DualPasswordOptionType symbols (the iota entries it currently consumes are gone). Ref pingcap#60587
