From f2d4bc6bf4c096a7c80e5ed85a94acb1e5864270 Mon Sep 17 00:00:00 2001 From: MPCoreDeveloper Date: Thu, 12 Nov 2026 12:07:34 +0100 Subject: [PATCH 01/13] build: pin the .NET 11 GA SDK and define Runtime Async once for the whole line .NET 11 GA shipped 2026-11-10, so master moves off the RC: global.json (both copies) pins 11.0.100 with rollForward latestPatch and no allowPrerelease, the five net11 workflows install 11.0.x without include-prerelease (ci-net10.yml untouched), and the server Dockerfile comment names the GA images. While doing it, Features=runtime-async=on turned out to be three hand-copied project lines (core, EventSourcing, its tests) while the other 72 projects compiled classic - although docs/net11/UPGRADE.md already described it as a property of the whole line. It is now defined once, in a new Directory.Build.targets, conditioned on net11.0, with false as the per-project opt-out. Why targets and not props: a TFM-conditioned switch in Directory.Build.props is evaluated before the project body, where $(TargetFramework) is still empty, so it silently never applies - measured, not reasoned (163 state machines and 71,4 B/call survived with the block in props; the same block in targets gave 2 and 0). Measured on the GA runtime, 1.000-call loop: an awaited, synchronously-completing async Task allocated 71.424 bytes before and 0 after; SharpCoreDB.dll went from 163 compiler-generated IAsyncStateMachine types to 2 (the async iterators, which runtime async does not cover at GA). Verified: SharpCoreDB.CI.slnf builds with the GA SDK (0 errors); core suite 2124 / 0 / 0 / 0. --- .github/workflows/benchmarks.yml | 7 +++--- .github/workflows/ci.yml | 24 ++++++++----------- .github/workflows/compatibility-smoke.yml | 5 ++-- .github/workflows/dependency-submission.yml | 7 +++--- .github/workflows/publish-manual.yml | 6 ++--- AGENTS.md | 9 ++++--- Directory.Build.targets | 17 +++++++++++++ README.md | 2 +- docs/performance/AUTONOMOUS_AGENT_BRIEF.md | 4 ++-- global.json | 5 ++-- .../SharpCoreDB.EventSourcing.csproj | 3 ++- src/SharpCoreDB.Server/Dockerfile | 3 ++- src/SharpCoreDB/SharpCoreDB.csproj | 5 ++-- src/SharpCoreDB/global.json | 5 ++-- .../SharpCoreDB.EventSourcing.Tests.csproj | 3 ++- 15 files changed, 59 insertions(+), 46 deletions(-) create mode 100644 Directory.Build.targets diff --git a/.github/workflows/benchmarks.yml b/.github/workflows/benchmarks.yml index fe1a8c9c..fd848898 100644 --- a/.github/workflows/benchmarks.yml +++ b/.github/workflows/benchmarks.yml @@ -53,12 +53,11 @@ jobs: with: fetch-depth: 0 - # The branch's global.json pins the .NET 11 RC SDK (net11.0 + C# 15 preview only). - - name: Setup .NET 11 (RC) + # The branch's global.json pins the .NET 11 GA SDK (net11.0 + C# 15 preview only). + - name: Setup .NET 11 (GA) uses: actions/setup-dotnet@v6 with: - dotnet-version: '11.0.100-rc.1.26425.128' - include-prerelease: true + dotnet-version: '11.0.x' - name: Build the comparative benchmark (Release) run: dotnet build "$BENCH_PROJECT" --configuration Release --framework net11.0 diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index c82560ea..69c0656d 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -20,9 +20,10 @@ permissions: contents: read env: - # .NET 11 SDK pin. `include-prerelease` stays until the GA SDK ships (2026-11-10); after that the value - # becomes '11.0.x' and the flag can be dropped.

Nothing is retrofitted: QueryResult, ExecuteResult and every ExecuteSQL signature stay byte-identical, and BuildResult deliberately stays a record hierarchy (a union there would break a shipped type). The union keyword form was chosen over the [Union] class shape in the design doc because the GA compiler generates that shape itself. Two canaries pin facts that would otherwise drift silently: - RuntimeAsyncCodegenTests fails when the runtime-async flag is dropped (-p:UseRuntimeAsync=false: 163 state machines and 71,4 B/call) and passes on the GA build (2 state machines, 0 B/call on an awaited synchronously-completing call). - UnionOutcomeTests carries no discard arm in any switch, so exhaustiveness is enforced by the compiler. Docs: UPGRADE.md gains the GA section and the measured Runtime Async limits (the awaited shape is the win; a blocking GetResult still materialises the task; async iterators keep their compiler state machine), UNION_TYPES_DESIGN.md records that the design shipped, and ROADMAP/INDEX are updated to match.

What the data says instead: inside every run the fastest rep is 50-70% above the median and the fastest rep agrees across runs to ~1%, a ~50 ms GC pause lands in 2 of 54 measured phases, and most slow passes carry one single-stage stall whose stage varies per pass. The mode is a per-rep disturbance, and the median is the wrong statistic for a 22-35 ms window. So the gate now reports and compares capability: - GateRow prints a `best` column (fastest of the reps); the verdict still uses the median. - --write-baseline records medians in raw/default and bests in rawBest/defaultBest. - When a baseline carries the bests, a capability table (best-to-best) decides the verdict and the spread is reported as information; median-only baselines keep the old behaviour exactly. - Recording is no longer gated on the rep spread (it is not a verdict - and on this box that gate made a baseline impossible: every attempt exited 2 with 2,63x-3,29x spreads), and instead refuses to write when any metric's best is more than 25% below the one on disk, which is what "a baseline recorded during a regression silently accepts that regression" is about. - SHARPCOREDB_PHASE_DIAG=1 adds wall vs process CPU vs GC counts/pause per phase. With that instrument the INSERT path got its first measured cut: NormalizeInsertRow allocated a bool[Columns.Count] per row and rebuilt it from the same columnIndexMap every time, but which columns a statement names is a property of the statement. Hoisting it to one mask per batch took the dictionary-free object[] overload from 1.838.776 to 1.787.608 bytes for 2.000 rows - 919 -> 894 B/row (-2,7%) - with identical behaviour, pinned by the new InsertBatchAllocationTests canary at a 900 B/row ceiling. Refuted in the same session and reverted, so nobody re-derives it: the identity-remap fast path (skip the normalized object[] when the column order matches) saves 3 B/row, because an insert never names the hidden AUTO column _rowid and the normalized row is required to carry it. Docs: docs/manual/performance.md documents server GC as the measured host lever (~1,75x INSERT, +20% READ, costs a heap per core) and records that GC frequency and tiering are not levers for this engine. The baseline file is re-recorded on the GA runtime with both statistics; review its diff before landing. Verified: gate PASSED on the capability comparison (raw INSERT 0,98x, default UPDATE 1,03x), suite 2124 / 0 / 0 / 0, canaries 57 / 0 / 0 / 0. --- docs/manual/performance.md | 7 + scripts/quiet-machine.ps1 | 4 + src/SharpCoreDB/DataStructures/Table.CRUD.cs | 23 +- .../Net11/InsertBatchAllocationTests.cs | 99 ++++++ .../Program.cs | 313 ++++++++++++++++-- .../baselines/README.md | 66 +++- .../baselines/dual-mode-baseline.json | 38 ++- 7 files changed, 508 insertions(+), 42 deletions(-) create mode 100644 tests/SharpCoreDB.Tests/Net11/InsertBatchAllocationTests.cs diff --git a/docs/manual/performance.md b/docs/manual/performance.md index d4a27984..dd46a899 100644 --- a/docs/manual/performance.md +++ b/docs/manual/performance.md @@ -362,6 +362,13 @@ parameter tuning (`M`, `efConstruction`, `efSearch`). | `PreparedStatements` (`db.Prepare(sql)` → `ExecutePrepared`/`ExecuteCompiledQuery`) | Compile once, execute many — removes parse + plan costs from the loop | | Collation `BINARY` | The only collation eligible for SIMD byte-compare paths | | Hash index on the lookup key | O(1) point access; enables the Direct/StructRow fast path | +| **.NET GC mode: `DOTNET_gcServer=1`** | On a many-core host the workstation GC leaves most of the write path's allocation on one collector thread.

Until the switch behind the mode is found, read a `REGRESSED` on +`raw UPDATE` / `raw READ` as **"wrong mode"**, not as a regression, and confirm it with a re-run before +acting. + +**What has been ruled out (session 87 of the worklog has the numbers).** Machine load: `INSERT` and `READ` inside those +same reps stayed within 1,07×/1,08×, and the new `SHARPCOREDB_PHASE_DIAG=1` line (wall vs process CPU vs GC counts/pause +per phase) shows the *slow* passes burning **more** CPU than the fast ones — CPU/wall ≥ 1, so the thread is not starved. +Warm-up depth on its own: both modes reproduced at 16 passes. GC frequency and GC mode: a 2 MB gen0 kept the fast mode +reachable, and `DOTNET_gcServer=1` kept the split (at higher absolute numbers). Tiering: `DOTNET_TieredCompilation=0` +reproduced the split too. **Hash-index maintenance:** `SHARPCOREDB_HASH_INDEXES=0` reproduced it as well (2,61×). The +workload data: the statement lists are fixed and prebuilt. The profiler's signature — **exactly one stage blowing up per +slow pass, a different one each time** (engine-write 54,1 ms against 1,9–6,3; row-locate-index 38,4/27,7 against 4–8; +in-place-patch 24,1 against 1,1–5,4) — is recorded there for whoever picks this up. + +## The UPDATE cell's mode is a per-rep disturbance — the same code, read with the wrong statistic (2026-11-12) + +Measured on the GA runtime, same binary, two consecutive gate runs (the new `best` column prints the fastest of +the three reps next to the median the verdict uses): + +| metric | run 1 median | run 1 best | run 2 median | run 2 best | +|---|---|---|---|---| +| raw INSERT | 209.866 | 213.675 | 223.954 | 225.234 | +| **raw UPDATE** | 251.636 | **390.672** | 247.158 | **432.851** | +| default INSERT | 183.422 | 188.285 | 186.334 | 187.020 | +| **default UPDATE** | 180.963 | **301.913** | 201.231 | **304.723** | + +Inside *every* run the fastest rep is **50–70 % above the median** on UPDATE, and `default UPDATE`'s best value +agrees across the two runs to **1 %** (301.913 vs 304.723) where the medians differ by 11 %. The consequence is the +whole finding: the "mode" is **not a different code path that a run selects** — it is a per-rep disturbance landing +in a 22–35 ms window (a ~50 ms GC pause appears in ~4 % of measured phases; most slow passes carry one unexplained +single-stage stall of 20–55 ms whose stage varies).

Two +ordering rules changed with it, each replacing an accidental behaviour with an explicit one: + +- **Recording is no longer blocked by the rep spread.** It used to be, by accident of ordering, which made the cell + unrecordable on any box with a disturbance in the UPDATE window (every attempt exited 2 with 2,63×–3,29× spreads). + A recording is not a verdict. The spread is still printed, loudly. +- **Recording refuses a materially worse capability.** If any metric's best rep comes out more than 25 % below the + best recorded on disk, nothing is written and the gate exits non-zero naming the metric — the protection the old + ordering was standing in for, and a stronger one, because a regression lowers every rep while a disturbance lowers + only one. +- **The spread gate still decides the median verdict**, and for a baseline recorded before this change (medians only) + the median comparison still decides, exactly as before.

PROMOTION_TO_MAIN's GA checklist is closed item by item - SDK pin, CI pins, unions shipped, gate run (INCONCLUSIVE then a documented PASSED, plus the capability statistic that made it certifiable), the baseline recorded by the owner, the image rebuilt on the GA base images - and item 5 is stated as owner-only rather than started, because version metadata, packing and publishing are the rail. docs/net11/GA_RELEASE_NOTES.md is the release note draft plus the checklist: what the repository verified (slnf 0 errors, 2124/0/0/0, canaries 57/0/0/0, gate PASSED, docs 9/9, image reports 11.0.0) and the six owner steps (version bump, tag, merge that packs and publishes, GitHub release, image push, optional quiet-box re-record). docs/performance/NET11_C15_PERFORMANCE_PLAN.md is the standing plan: what is already in place, where the time actually goes per UPDATE stage, the refuted-dial list (including the identity-remap fast path), the UPDATE mode resolved as a statistic, phases P0-P3 and the zero-regression rails. WORKLOG carries session 87 and its eight addenda: the GA upgrade, the runtime-async measurement, the union implementation, the UPDATE mode hunt (seven refutations), the capability gate, the INSERT cut, the refuted identity path, and the "no regression against the previous version" check (gate against the 2026-09-27 baseline: PASSED, worst cell 1,08x, UPDATE faster on both arms). --- docs/CHANGELOG.md | 7 + docs/net11/GA_RELEASE_NOTES.md | 80 +++++++ docs/net11/PROMOTION_TO_MAIN.md | 64 ++++++ .../performance/NET11_C15_PERFORMANCE_PLAN.md | 112 ++++++++++ docs/performance/WORKLOG.md | 207 ++++++++++++++++++ 5 files changed, 470 insertions(+) create mode 100644 docs/net11/GA_RELEASE_NOTES.md create mode 100644 docs/performance/NET11_C15_PERFORMANCE_PLAN.md diff --git a/docs/CHANGELOG.md b/docs/CHANGELOG.md index 71dd839d..92e20a3c 100644 --- a/docs/CHANGELOG.md +++ b/docs/CHANGELOG.md @@ -11,12 +11,19 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0 > bucket had collected since the `v2.1.1` tag — the statement-path literal scanner below — **shipped in > `[2.1.2]`**. New entries start here. +### Added + +- **Opt-in C# 15 union outcomes (`SharpCoreDB.Unions`).** `QueryOutcome` (rows / not found / failure), `ExecuteOutcome` (rows affected / failure) and `TableLookup` (found / missing) ship as `union` declarations with seven `record class` case types (`src/SharpCoreDB/Net11/Unions/UnionOutcomes.cs`), so a `switch` over them is exhaustive at compile time — dropping an arm is a build error. Purely additive: `QueryResult`, `ExecuteResult` and every `ExecuteSQL` signature are byte-identical, and `BuildResult` is deliberately **not** retrofitted (that would break a shipped type; it stays a `record` hierarchy). Unions are structs and case values box into `IUnion.Value`, so both pattern matching and generic inspection work. Tests: `tests/SharpCoreDB.Tests/Net11/UnionOutcomeTests.cs` — 3/3, with no discard arm in any switch, which is what makes exhaustiveness a compiler guarantee rather than a runtime assertion. +- **GA-runtime validation recorded for this line.** The write-path regression gate was run on the GA runtime: the first attempt was `INCONCLUSIVE` (exit 2, worst rep spread 3,20× on `default UPDATE`, rep 1 coldest), and after one `scripts/quiet-machine.ps1` check the single documented re-run came out **`GATE PASSED` (exit 0) with 8/8 metrics `ok`, worst rep spread 2,39×, `raw UPDATE 0,61×` / `default UPDATE 0,75×`** — faster than the recorded baseline, nothing above 1,08× against a 1,50× tolerance. No new baseline was recorded in that pass: the box was `NOISY` (`WSearch`, elevation-only) and recording one requires `QUIET`. It was recorded afterwards from an elevated shell (`quiet-machine.ps1 -Apply -StopServices` stopped `WSearch` and made the Defender probe effective, `2026-11-12T09:23:01Z`, 3 reps) - and that exposed an open measurement defect rather than closing the item: the gate's `raw UPDATE` cell picks a mode of ~215.000 or ~420.000 ops/sec (1,86-1,95x) and holds it, so the fresh reference failed `raw UPDATE 2,05x` minutes later on the same binary and its re-run came out `INCONCLUSIVE` (2,55x). Machine load, warm-up depth and the workload data are ruled out (`INSERT`/`READ` in the same reps stayed within 1,07x/1,08x; 16 warm-up passes produced one fast and one slow run); `baselines/README.md` carries the defect and session 87 of the worklog the profiler signature. The baseline is kept - the owner's decision - until the switch behind the mode is found.The server image rebuilds on the GA base images (`sharpcoredb-server:net11-ga`, 604 MB, reports runtime `11.0.0`). + ### Fixed - **A surplus value in a batched `INSERT … VALUES` is rejected instead of silently dropped — the last copy of the known-issue-7 truncation.** The prepared-insert fast path, the one `ExecuteBatchSQL` uses for bulk inserts, stopped counting a tuple at the table's column count: `INSERT INTO docs VALUES (1, 'a', 0,5, 21)` against a three-column table bound the first three values, discarded the rest and **succeeded**, where the statement path has rejected that shape since `[2.1.2]`. Both paths now throw, and the message names the table, the tuple and both counts; a *short* tuple keeps its documented meaning (the missing columns fall to `NULL`). Found by `tests/SharpCoreDB.Tests/PreparedInsertValuesParsingTests.cs`, which parses every case through **both** prepared parsers and asserts they agree — nothing covered either one before, which is how the two could drift. Verified on this tree: core **2118 / 0 failed**, and the §7 reproduction published in `docs/sharpcoredb-known-issues.md` still prints the fixed output for all five bound-value shapes. ### Changed +- **The line builds on the .NET 11 GA SDK, and Runtime Async now covers every net11.0 project — one awaited, synchronously-completing call allocates nothing at all.** .NET 11 GA shipped 2026-11-10, so `global.json` pins `11.0.100` with `rollForward: latestPatch` and `allowPrerelease` is gone (in both copies; an RC SDK no longer satisfies the pin), and the five workflows that build this line moved from the RC build string to `11.0.x` without `include-prerelease` (`ci-net10.yml`, the parked net10 line, is untouched). Separately, `Features=runtime-async=on` existed as **three hand-copied project lines** — the core engine, `SharpCoreDB.EventSourcing` and its test project — while the other 72 projects compiled classic, although `docs/net11/UPGRADE.md` already described it as a property of the whole line; it is now defined **once** in a new repository-root `Directory.Build.targets`, conditioned on `net11.0`, with `false` as the per-project opt-out. Measured on the GA runtime with a 1.000-call loop: an awaited call to a synchronously-completing `async Task` allocated **71.424 bytes before (71,4 B/call) and 0 bytes after**, and `SharpCoreDB.dll` went from **163 compiler-generated `IAsyncStateMachine` types to 2** — the two async iterators (`ColumnarDataReader.ReadBatchesAsync`, `PageBasedDataWriter`), which runtime async does not cover at GA. Two shapes are documented rather than assumed: a **non-awaited** call (`.GetAwaiter().GetResult()` or a discarded task) still materialises the `Task` at **72,0 B/call**, and an `async IAsyncEnumerable` iterator keeps its compiler state machine. Note the placement trap this closed: a TFM-conditioned switch in `Directory.Build.props` is evaluated before the project body, where `$(TargetFramework)` is still empty, so it silently never applies — `Directory.Build.targets` is imported after it. Canary: `tests/SharpCoreDB.Tests/Net11/RuntimeAsyncCodegenTests.cs`, which fails on both facts with `-p:UseRuntimeAsync=false` (163 state machines; 71,4 B/call) and passes on the GA build. Verified on this tree: `SharpCoreDB.Tests` **2120 / 0 failed / 0 errors / 0 skipped in 90,0 s**, `SharpCoreDB.CI.slnf` builds with the GA SDK (0 errors). +- **Internal: the batch INSERT path no longer allocates a presence mask per row.** `Table.NormalizeInsertRow` built a `bool[Columns.Count]` for every row out of the same `columnIndexMap`; which columns a statement names is a property of the *statement*, so the mask is derived once per batch now. Measured through the new `InsertBatchAllocationTests` canary (2.000 rows, dictionary-free `object[]` + column-order overload): **1.838.776 → 1.787.608 bytes, i.e. 919 → 894 B/row (−25 B/row, −2,7 %)**, behaviour identical — an absent column still takes its default and an explicit `NULL` still stays `NULL`. The session 87 worklog entry carries the per-stage attribution (`validate-only` 384 B/row, `encode` 192, `engine-write` 191, `row-locate` 77, `index-maint` 38) and the gate verdict that followed it. - **Internal: one VALUES splitter and one literal skipper instead of five copies.** `PreparedInsertStatement.ParseValues` and `ParseValuesToArray` carried identical splitting loops; they now share a `ValueRangeEnumerator` `ref struct` (allocation-free, one branch per character, identical behaviour). The two canonical-shape scanners in `Database.Batch.cs` re-implemented the quote machine a third and fourth time and now call `SqlLiteralScanner` through a `TrySkipLiteral` helper, and `PreparedStatement`'s `?`-position extractor — a byte-for-byte copy of `ParameterBinder.ExtractPositionalParameterPositions` — is gone. This is what the CI Sonar gate flagged (duplication above the 3 % ceiling on new lines). ## [2.1.2] - 2026-10-26 diff --git a/docs/net11/GA_RELEASE_NOTES.md b/docs/net11/GA_RELEASE_NOTES.md new file mode 100644 index 00000000..5b4d265f --- /dev/null +++ b/docs/net11/GA_RELEASE_NOTES.md @@ -0,0 +1,80 @@ +# .NET 11 GA release — notes and checklist + +> Status: **prepared, not released.** Everything on the repository side is done and verified; the steps in +> §4 are owner actions by policy (version metadata, tag, merge/publish).

Tests: +`tests/SharpCoreDB.Tests/Net11/UnionOutcomeTests.cs`, **3/3**, whose switches carry no discard arm so +exhaustiveness is a compile-time guarantee rather than a runtime assertion. + +**Item 4 — the gate ran on the GA runtime; the Docker image is rebuilt.** The gate's first run came out +`INCONCLUSIVE` (exit 2) with a worst rep spread of **3,20×** on `default UPDATE` (98.561 / 315.843 / +196.317 ops/sec — rep 1 coldest, i.e. a cold process rather than load). Per the standing protocol that is +a statement about that run, so: one `scripts/quiet-machine.ps1` check, then **one documented re-run → +`GATE PASSED` (exit 0), 8/8 metrics `ok`, worst rep spread 2,39×**, with `raw UPDATE 0,61×`, +`default UPDATE 0,75×`, `raw READ 0,91×` — faster than the recorded baseline — and nothing above 1,08× +against a 1,50× tolerance. Both runs are archived (`artifacts/ga-gate.txt`, +`artifacts/ga-gate-rerun.txt`). + +**The baseline was recorded — by the owner, from an elevated shell, and it exposed a defect.** `quiet-machine.ps1 -Apply -StopServices` stopped `WSearch` and made the Defender probe effective, and the baseline was recorded at **`2026-11-12T09:23:01Z`** (3 reps): raw `I 217.844 / R 139.008 / U 410.145 / D 452.095`, default `I 199.184 / R 150.719 / U 247.619 / D 181.701`. The gate then **failed against it minutes later on the very same binary** — `raw UPDATE 2,05×` (410.145 → 199.953) — and the documented re-run came out `INCONCLUSIVE` (exit 2, worst spread 2,55× on `raw UPDATE`: 462.444 / 484.116 / 189.843). The finding is that the `raw UPDATE` cell **picks a mode of ~215.000 or ~420.000 ops/sec (1,86–1,95×) and holds it**; `raw READ` has a milder version (139.000 vs ~200.000). Ruled out with measurements, not reasoning: machine load (`INSERT`/`READ` in those same reps stayed within 1,07×/1,08×), warm-up depth (8 passes: spreads 2,39/2,55/3,20×; 16 passes: one fast run at 1,08× *and* one slow run at 1,22× — so the deeper warm-up makes the reps agree with each other and still lets the process disagree with the baseline), and the workload data (fixed, prebuilt statement lists). The profiler signature is recorded: the whole batch path scales together (parse 3,9 → 25,9 ms, engine-write 2,0 → 37,8 ms, commit-overwrites 2,2 → 20,5 ms per 10.000 updates) while the one-off `row-snapshot` stage stays flat. **The owner decided to keep the new baseline**; `baselines/README.md` carries the defect for whoever reads the guard, and finding the switch is the first item in the worklog's `NEXT:` line. + +Docker: the daemon was not running at the start of the session; it was started and the image rebuilt on +the GA base images — **`sharpcoredb-server:net11-ga`, 604 MB, id `4fb97e58b276`**, with +`docker run --rm --entrypoint dotnet sharpcoredb-server:net11-ga --list-runtimes` answering `11.0.0` +(runtime present and functional). + +**Item 5 — release metadata: NOT done here, deliberately.** Version fields, ``, +package metadata, packing and publishing are an owner action under the standing rail, so only the +narrative/docs were updated in this session (`docs/CHANGELOG.md`, `docs/net11/UPGRADE.md`, `ROADMAP.md`, +this document).

It is now defined **once**, in a new repository-root `Directory.Build.targets`, TFM-conditioned, with `false` as the per-project opt-out. The placement is the finding: a TFM-conditioned switch in `Directory.Build.props` never applies, because props are evaluated before the project body where `$(TargetFramework)` is still empty — measured, not reasoned (`Features` resolved to `;runtime-async=on` per project yet **163** state machines and **71,4 B/call** survived; moving the same block to targets produced 2 and 0). + +**The Runtime Async numbers, measured on the GA runtime** (1.000-call loop, warm-up 2.000): an **awaited**, synchronously-completing `async Task` allocated **71.424 bytes (71,4 B/call) before → 0 bytes after**; `SharpCoreDB.dll` went `163 → 2` compiler-generated `IAsyncStateMachine` types, and the 2 are the async iterators (`ColumnarDataReader.ReadBatchesAsync`, `PageBasedDataWriter`) that runtime async does not cover at GA.

Warm-up therefore makes the three reps agree with each other and still lets the process disagree with the baseline: it converts an honest `INCONCLUSIVE` into a confident `FAILED`. + + +**Decision — the default stays 8.** The 16 default was reverted after experiment 3: it does not fix the mode, and it moves the failure from exit 2 ("no verdict") to exit 1 ("a confident wrong verdict") on a metric whose mode is unexplained. The three experiments and their numbers now live in `ResolveWarmupReps`'s own XML comment, so the next session starts from them instead of repeating them, and `baselines/README.md` carries the defect for anyone reading the guard: treat `REGRESSED` on `raw UPDATE` / `raw READ` as *"wrong mode"* until the switch is found. Ruled out by measurement, not reasoning: machine load (`INSERT`/`READ` stable inside the same reps), warm-up depth (both modes reproduced at 16), the workload data (fixed, prebuilt statement lists), the harness's own string formatting (outside the timed window since session 46), and the fixed-width layout (`[diag]` printed `IsFixedWidthRecords=False` on every rep seen today). + +**Still open — and this is the head of `NEXT:`.** The switch behind the mode is not identified: 210–220k versus 400–430k on the same 10.000-statement `ExecuteBatchSQL` + `Flush` window, with the batch path uniformly ~2× slower and INSERT/READ untouched, points at something the engine selects per process or per run (a path/layout decision made once, a GC mode, a hash seed, or a background drain landing inside the window). Session 78 already showed `DOTNET_TieredPGO` / `DOTNET_TieredCompilation` do not explain this exe's ramps, so the next experiment should discriminate the engine's own per-process decisions rather than re-time the same shape. + +- Verification: the harness still builds (0 errors) after the comment and the default revert; the engine is untouched in this addendum, so the core suite result from the main entry stands (**2123 / 0 failed / 0 errors / 0 skipped**). Evidence files: `artifacts/ga-gate-after-baseline.txt`, `ga-gate-after-baseline-rerun.txt`, `ga-profile-update.txt`, `ga-gate-warmup16.txt`, `ga-gate-warmup16-a.txt`, `ga-quiet-1..4.txt`. +- Commit: none — nothing committed or pushed. +- NEXT: (1) **OPEN (measurement, top of the queue)** — find the `raw UPDATE` mode switch: ~215k vs ~420k (1,86–1,95×) on an unchanged binary, the batch path uniformly slower, INSERT/READ stable in the same reps, warm-up depth refuted. Until it is found the recorded GA baseline is a coin flip on `raw UPDATE`/`raw READ`, which `baselines/README.md` now states. (2) **owner-only** — the `2.1.x` version/`PackageReleaseNotes`/metadata refresh, the tag, and the merge that publishes. (3) unchanged queue head — session 81's `NEXT:` §5.1 INSERT item (i), the identity-remap fast path for `InsertBatch(table, rows, columns)` when the column order already matches the table order (112 B/row on the array arm). Still carried from session 86: `codecov/project` is never posted for this repository, and the `unittests` flag registry entry survives its removal from `codecov.yml` — both need Codecov dashboard/app actions outside this repository. + + +### 2026-11-12 (session 87, addendum 2) — MAXPERF: one measured .NET 11 GA win (server GC, 1,75× INSERT) and five refutations that leave the UPDATE mode unexplained + +- Session: 87 (addendum — the owner asked for maximum performance from the .NET 11 GA / C# 15 line, so the open `raw UPDATE` mode was attacked with dials instead of inference). +- Command(s): gate ×5 more on the same binary — default, `DOTNET_gcServer=1`, `DOTNET_GCgen0size=0x200000`, `DOTNET_TieredCompilation=0`, and one with the new `SHARPCOREDB_PHASE_DIAG=1`. +- Regime: GA SDK `11.0.100` / runtime `11.0.0`, Release/JIT, `SHARPCOREDB_BENCH_TEMP=D:\scdb-bench-tmp`, `WSearch` stopped, Docker Desktop and build servers down before each run; each dial run names its `DOTNET_*` variable and none was combined with another. `raw` arm = `NoEncryptMode=true`. +- Verdict: **KEPT one lever (server GC), REFUTED five hypotheses, and the UPDATE mode is still unexplained but now has a decisive instrument.** + +**The win — server GC is worth ~1,75× on INSERT on this box.** `DOTNET_gcServer=1`, same binary, same protocol: `raw INSERT` **359.637 / 347.407 / 343.264** ops/s (spread 1,05×) against **~200.000** (192–219k) with the default workstation GC; `raw READ` **247.614 / 217.912 / 221.617** against 190–209k (**+20%**); `default UPDATE` 264.571 / 374.321 / 351.345 against 143–296k. The gate **PASSED** (exit 0) with `default INSERT 0,65×` — i.e. **1,54× faster than the recorded baseline** — and `raw INSERT 1,00×`, `default READ 1,04×`. That is the answer to "the GA line should be faster": on the write path it is, and the remaining headroom is in GC mode, not in a micro-tuned JIT. Cost is memory (a heap per core), so it is a server/benchmark setting, not an embedded default — `SharpCoreDB.Server` already sets `DOTNET_gcServer=1` in its Dockerfile, and the lever is now documented in `docs/manual/performance.md` §7.7 with these numbers. + + +**The five refutations, in the order they were tested.** (1) *Machine load* — INSERT and READ in the same reps stay within 1,03–1,14× while UPDATE swings 2,4–2,6×; load would move all four. (2) *GC frequency* — `DOTNET_GCgen0size=0x200000` (a 2 MB gen0, many more collections inside the window) left the fast mode reachable (`raw U 415.397 / 159.271 / 254.274`, spread 2,61×) and did not depress INSERT (201–208k, spread 1,03×), so the window is not GC-pause-bound. (3) *GC mode* — `DOTNET_gcServer=1` raised every absolute number and **kept the split** (`raw U 524.826 / 483.872 / 217.851`, 2,41×). (4) *Tiering / code quality* — `DOTNET_TieredCompilation=0` reproduced the split too (`raw U 341.660 / 278.298 / 189.449 …`, worst 2,16×), so the mode is not a Tier-0-versus-Tier-1 artefact, which also re-confirms the earlier warm-up result from the other direction. (5) *The data and the harness formatting* — the statement lists are prebuilt, all 10.000 statements are distinct by design, and `[diag] docs layout` printed `IsFixedWidthRecords=False` on every rep. + +**The instrument that should answer it next — new, `SHARPCOREDB_PHASE_DIAG=1`.** Each phase now prints `wall`, process `cpu`, `cpu/wall`, gen0/1/2 counts and GC pause time (`PhaseSnapshot`/`PrintPhaseDiag` in the harness; with the switch off nothing is printed, so every existing artefact stays byte-identical). First reading, 11 passes: the *slow* UPDATE passes burn **more** CPU than the fast ones — 53,8 ms wall / 78,1 ms CPU and 56,8 / 62,5 against 23,1 / 15,6 and 23,4 / 31,2 — so the thread is not being starved (that would be CPU ≪ wall). The same 10.000 updates therefore do 3–5 Windows timer quanta of CPU in the slow mode against 1 in the fast one. Note the caveat this measurement carries: `Process.TotalProcessorTime` is quantised at ~15,6 ms on this box, so treat those figures as ±1 quantum and read the *ratio*, not the millisecond. + +**What that leaves.** The slow mode costs more CPU for the same work while tiering, GC mode, GC frequency, warm-up and load are all excluded — so the difference is in the engine's own per-run state or in which work the batch path delegates to (a cached-versus-recomputed plan, an index/FSM decision, or a relocation-versus-in-place distribution), and the new per-phase CPU split is what will localise it: run it with `SHARPCOREDB_MAIN_PROFILE_UPDATE=1` in the same pass to attribute the extra CPU to a stage, on a process that reports its own per-iteration counters. The one thing that must not happen is a baseline recorded while this is unexplained — this session's earlier addendum is exactly that story. + +- Verification: harness builds 0 errors with the new instrument; the engine is untouched in this addendum (no `src/` change), so the core suite result from the main entry stands (2123 / 0 / 0 / 0) and the durability/format canaries inside it are unaffected. Evidence files: `artifacts/ga-gate-gcserver.txt`, `ga-gate-smallgen0.txt`, `ga-gate-notc.txt`, `ga-phase-diag.txt`. +- Commit: none — nothing committed or pushed. +- NEXT: (1) **OPEN (measurement, top of the queue)** — localise the `raw UPDATE` mode with the new instrument: `SHARPCOREDB_PHASE_DIAG=1` + `SHARPCOREDB_MAIN_PROFILE_UPDATE=1` in one pass, then attribute the extra CPU to a stage; the mode costs 3–5 timer quanta of CPU against 1, with load/GC/tiering/warm-up/data excluded. (2) **landed this session, adopt it** — server GC is the measured write-path lever (`~1,75×` INSERT, `+20%` READ, gate INSERT `0,65×`); it is documented in `docs/manual/performance.md` §7.7 and already set in the server image. (3) **owner-only** — the `2.1.x` version/`PackageReleaseNotes`/metadata refresh, the tag, and the merge that publishes. (4) unchanged queue head — session 81's `NEXT:` §5.1 INSERT item (i), the identity-remap fast path for `InsertBatch(table, rows, columns)` when the column order already matches the table order (112 B/row on the array arm). Still carried from session 86: `codecov/project` and the `unittests` flag registry entry. + + +### 2026-11-12 (session 87, addendum 3) — the plan is written, the UPDATE mode is narrowed to "one stage per pass", and P1's first optimisation is refuted by measurement before a line of it is written + +- Session: 87 (addendum — owner chose the parallel order: P0 mode-hunting and P1 allocation work at once). +- Command(s): `--gate --gate-factor=1.5` with `SHARPCOREDB_HASH_INDEXES=0` + `SHARPCOREDB_PHASE_DIAG=1`; the same gate with `SHARPCOREDB_PHASE_DIAG=1` + `SHARPCOREDB_MAIN_PROFILE_UPDATE=1` + `SHARPCOREDB_WARMUP_REPS=2`; a `Dictionary` capacity probe (200.000 iterations, GA runtime, `--gcServer` irrelevant here); code reads only — `Database.Batch.cs:800-920` (`TryScanCanonicalDml`), `:1088-1160` (`TryParseUpdateForBatch`), `Table.CRUD.cs:4410` (`UnquoteSqlLiteral`), plus the archived `artifacts/s79-parse-probe.txt`. +- Regime: GA SDK `11.0.100` / runtime `11.0.0`, Release/JIT, `WSearch` stopped, Docker Desktop and build servers down. No engine source changed in this addendum. +- Verdict: **P0 narrowed by a sixth refutation and a much sharper signature; P1's first candidate refuted by measurement — so it was NOT implemented, which is the plan's own rule ("the same is not a win").** + +**P0, refutation 6 — hash-index maintenance is not the switch.** `SHARPCOREDB_HASH_INDEXES=0`, same protocol: `raw UPDATE 245.922 / 185.492 / 484.453` (spread **2,61×**) — the mode survives without any hash index to maintain, and INSERT/READ stay put again (INSERT 1,06×, READ 1,23×). The index-update drain (`IndexManager._updateTask`) is therefore not the deferred work the earlier addendum suspected. + +**P0, the signature that replaces the guesses.** With `SHARPCOREDB_MAIN_PROFILE_UPDATE=1` and `SHARPCOREDB_PHASE_DIAG=1` in the same pass, ten profiled UPDATE phases line up as (ops/sec · which stage is abnormal): +`194.011 · parse 20,5 ms` · `145.419 · row-locate-index 38,4` · `304.151 · none` · `178.380 · in-place-patch 24,1` · `442.513 · none` · `212.486 · row-locate-index 27,7` · `293.310 · none` · `130.718 · engine-write 54,1` · `421.956 · none` — against fast-pass baselines of parse 3,8–7,0, engine-write 1,9–2,1, locate 4,0–7,5, patch 1,1–1,3 ms. In a slow pass **exactly one stage blows up, and which one it is changes from pass to pass**, while process CPU rises with it (`cpu/wall` 1,02–1,45 in the slow passes, 0,66–0,69 in the fast ones). A whole-phase code-path change would move every stage; this moves one, arbitrarily — the shape of a **one-off event landing inside whichever stage happens to be running**. That is why every dial tested so far (warm-up, GC, tiering, indexes, load) left it untouched: none of them targets the event. + +**P1 — the candidate is dead, measured before implementation.** `Database.Batch.cs:1112` builds `new Dictionary { [setCol] = … }` per statement, and the archived session-79 probe put that at **240 B / 94,5 ns per statement** — the largest single piece of the 528 B the profiler attributes to `parse`. The obvious fix is a capacity hint; measured (200.000 iterations): default ctor **216,0 B / 97,4 ns**, `new Dictionary(1)` **216,0 B / 89,9 ns**, capacity 2 **216,0 B / 88,4 ns** — **zero bytes saved**, because the first insert allocates the same minimum structure either way. The second candidate, `Table.UnquoteSqlLiteral` (32 B/statement in the same probe), **already returns the caller's instance** since session 79 (`Table.CRUD.cs:4410`). So the remaining per-statement allocation is 5× `ToString` 128 B + `ParseValue` 24 B + the dictionary 216 B + list growth ≈40 B ≈ **410 B**, and cutting it needs a structural change to what the classifier hands the core (P2), not a tweak. + +**And the reason that matters more than the bytes:** the same probe arithmetic puts the whole classification at ~0,3–0,5 µs of the ~2,5 µs a typical UPDATE costs (2,5–3 µs/statement × 10.000 = 25–30 ms). Allocation is therefore ~12 % of the per-statement cost, so **allocation-only work has a single-digit-percent ceiling on UPDATE** — smaller than the measurement's own mode, which is why P1 now moves to the INSERT path (stable, 1,03–1,14×) and the UPDATE allocation cut is reclassified as P2 and gated on a *timing* win. + +- Plan artefact: `docs/performance/NET11_C15_PERFORMANCE_PLAN.md` (phases, rails, the refuted list, the next discriminating experiments). +- Verification: no engine source changed; docs-only. `SharpCoreDB.Tests` documentation-consistency **9/9** after the new document. +- Commit: none — nothing committed or pushed. +- NEXT: (1) **P0, next discriminating experiment** — `SHARPCOREDB_WAL_DURABILITY` (benchmark-only) on the gate; if the one-off event is a WAL/fsync landing in the window, the mode disappears, and if it does not, add a settle step between phases (index drain + flush loop + maintenance timer) and re-measure. Do not re-run the six refuted dials. (2) **P1 on INSERT** — profile `InsertBatch` (`SHARPCOREDB_WRITE_PROFILE`), cut the top allocation, prove it with a red→green allocation canary.

Compaction was the live candidate — `ColumnarAutoCompactionThreshold` defaults to 1000 and fires on the *sum* of UPDATE+DELETE, i.e. ~10× inside a 10.000-update phase — but `SHARPCOREDB_COMPACTION_THRESHOLD=1000000000` (confirmed applied: the `REGIME (overridden)` line carries it) still produced `raw U 393.522 / 191.393 / 203.659` (2,06×). **Refutation 7.** + +**What the phase data had been saying all along.** Across 54 measured UPDATE phases the GC pause is 3–9 ms typically, with **two outliers of ~50 ms** (48,7 and 50,4 ms — 2 of 54, ≈4 %), and the slowest pass in the attribution run was **50,4 ms of pure pause inside a 76,5 ms window**. The other slow passes carry 5–8 ms of pause but one stage stalled 20–55 ms (`engine-write` 54,1, `row-locate-index` 38,4/27,7, `in-place-patch` 24,1 against fast-pass baselines of 1,9–6,3, 4–8 and 1,1–1,3). Against a best-case phase of 22–35 ms, any single one of those events doubles the cell. + +**So the harness now reports the capability, not just the median.** `GateRow` prints a `best` column — the fastest of the three reps, filters negative (`FAILED`) entries, and **the verdict still uses the median**, so no pass/fail changes. Two consecutive runs, same binary: + +| metric | run 1 median | run 1 best | run 2 median | run 2 best | +|---|---|---|---|---| +| raw INSERT | 209.866 | 213.675 | 223.954 | 225.234 | +| **raw UPDATE** | 251.636 | **390.672** | 247.158 | **432.851** | +| default INSERT | 183.422 | 188.285 | 186.334 | 187.020 | +| **default UPDATE** | 180.963 | **301.913** | 201.231 | **304.723** | + +Inside *every* run the fastest rep is **50–70 % above the median** on UPDATE, and `default UPDATE`'s best agrees across the two runs to **1 %** (301.913 vs 304.723) where the medians differ by 11 %. That is the answer to the question six dials could not answer: the code is not selecting a mode — **the median is measuring how often a disturbance lands**, and three reps are too few for that to be stable. INSERT, whose window is 100k rows, shows median ≈ best (209.866 vs 213.675), which is exactly what a metric with enough work per rep looks like. + +**What this changes, and what it does not.** No verdict moved, no engine source changed, and nothing about the six refuted dials was retried. What remains is a decision the rail puts with the owner: **comparing best-of-reps against a median-recorded baseline is apples to oranges** — it reads as `raw UPDATE` 1,63× "REGRESSED" while the bests themselves are stable — so a capability comparison needs the baseline **recorded with the same statistic**. Until that is taken, `baselines/README.md` now says to read the `best` column as capability and the median as instability, and never as "the engine got faster or slower". + +- Verification: harness builds **0 errors** with the additive column and the `BestOf` helper; the gate's output gained one column and two footer lines, nothing else; no `src/` change, so the core suite stands at 2123 / 0 / 0 / 0 and the durability/format canaries are untouched. +- Commit: none — nothing committed or pushed. +- NEXT: (1) **owner decision** — re-record `baselines/dual-mode-baseline.json` with the **best-of-reps** statistic (and keep the median in the file for the disturbance report), so capability can be compared like-for-like; this is the last step P0 needs and the rail makes it yours. (2) **P1 on INSERT** — profile `InsertBatch` (`SHARPCOREDB_WRITE_PROFILE`), cut the top allocation, prove it with a red→green allocation canary; INSERT's median ≈ best (209.866 vs 213.675) means a win there is measurable the day it lands.

No `src/` change. +- Verdict: **P0 complete — the guard now measures capability, records it, protects it, and passes on it; the UPDATE cell is no longer a coin flip.** + +**The first thing the owner's command found: recording was impossible.** `--write-baseline` came back **exit 2 with nothing written** — the record call sat *behind* the rep-spread check, so on a box where a disturbance lands in the 22–35 ms UPDATE window (spread 2,63×–3,29× on every attempt today) a baseline could never be recorded at all. That is why the file still carried the 09:23 timestamp after the owner's run, and it is an accident of ordering rather than a decision: the spread rule exists to stop a *verdict* being drawn from a run whose reps disagree ("cannot support any verdict, however it compares"), and a recording is not a verdict. + +**What changed.** (1) The recording runs before the spread gate, and the spread is printed loudly instead of enforced. (2) The protection that ordering was standing in for is now explicit and stronger: `NewCapabilityWorseThanRecorded` refuses to write when any metric's best-of-reps is **more than 25 % below the best on disk**, naming the metrics — a regression lowers *every* rep, while a disturbance lowers only one, so this catches what "a baseline recorded during a regression silently accepts that regression" warns about without being tripped by noise. (3) `--write-baseline` records **both** statistics: `raw`/`default` = the median of each arm's reps, `rawBest`/`defaultBest` = its fastest. (4) When a baseline carries the bests, the gate prints a **capability table (best-to-best) and that table decides the verdict**; the spread is then reported as the median's instability instead of blocking. (5) Median-only baselines keep the old behaviour exactly, spread gate included, so nothing that already exists changes meaning. + +**The first run under the new protocol.** Baseline recorded `2026-11-12T10:29:34Z`, medians `raw UPDATE 231.167` / `default UPDATE 235.886`, bests `raw UPDATE 477.824` / `default UPDATE 332.458`. The gate on the next run: medians spread **3,25×** → "the medians above support no verdict — but this baseline records the capability statistic, so the capability comparison below decides"; capability **8/8 `ok`**, worst cell `raw UPDATE` **1,19×** (477.824 → 399.960), everything else 0,92×–1,03× → **`GATE PASSED`, exit 0.** For contrast, the same run's median table would have read `default UPDATE 235.886 → 229.542 = 1,03×` while one rep measured 99.958 ops/sec — the disturbance that used to flip the verdict is now visible as a number instead of deciding the outcome. + +- Verification: harness builds **0 errors**; `SharpCoreDB.CI.slnf` **Build succeeded, 0 errors**; documentation-consistency **9/9**; no `src/` change, so the core suite stands at **2123 / 0 / 0 / 0** and the durability/format canaries are untouched.

First run with a deliberately impossible ceiling printed the real figure: **1.838.776 bytes for 2.000 rows = 919 B/row**. The ceiling now sits at 950 B/row, so a change that allocates more turns the test red, and the optimisation is expected to *lower* it. Reading the path for the cut: `Database.InsertBatch` copies at most one array (`rows as object[][] ?? [.. rows]`), and the 919 B lives in `Table.ValidateAndSerializeBatchOutsideLock` — a normalized `object[]` per row (`NormalizeInsertRow`), a `byte[]` per row (`SerializeRowExact`), plus whatever `InsertBatchCriticalSection` adds per row. That is the next measurement, and the canary is what will prove it. + +- Verification: canary **1/1** at the new ceiling; full suite **2124 / 0 failed / 0 errors / 0 skipped in 82,6 s**.

One reading worth recording because the table invites a double count: `validate` (576 B/row) is the *outer* stamp and equals `validate-only` + `encode` (384 + 192 = 576), so the stages are not additive across the nesting — the honest total is ~690 B/row of stamped allocation against 919 measured, the remainder being the unstamped `List` growth and the critical section. + +**The cut.** `NormalizeInsertRow` allocated a `bool[this.Columns.Count]` **per row** and rebuilt it from the same `columnIndexMap` every time — but which columns a statement names is a property of the *statement*, not of the row. The mask is now derived once per batch in `ValidateAndSerializeBatchOutsideLock` and passed in; the per-row loop no longer allocates it and no longer re-marks it. (An obvious alternative — `stackalloc` per row — was rejected in favour of the hoist: it also removes the per-row marking loop, and it keeps the method's signature honest about where the mask comes from.) Behaviour is unchanged by construction: presence only ever decided *absent → default* vs *explicit NULL → NULL*, and that decision cannot vary inside one batch. + +**Measured, red→green both ways.** Before: **1.838.776 B / 2.000 rows = 919 B/row** (printed by the canary with a deliberately impossible ceiling). After: **1.787.608 B = 894 B/row** — a **−25 B/row (−2,7 %)** that the canary now pins with a 900 B/row ceiling, so a change that allocates more turns it red. Then the wider rails a write-path change owes: full suite **2124 / 0 failed / 0 errors / 0 skipped in 82,0 s** (all eight standing canaries inside it) and the gate against the capability baseline — **`GATE PASSED` (exit 0)**, capability `raw INSERT` 0,99×, `default INSERT` 0,99×, `raw UPDATE` 1,12×, `default UPDATE` 1,11×. + +**What this says about the remaining 894 B/row, and it is the honest part.** The measured stages say the rest is *work*, not waste: the serialized record (`encode`, 192 B/row — the payload itself), the engine write (191), the index maintenance the table's auto-created hash indexes require (38), and the normalized row array the critical section consumes. The one structural saving left on this path is the one session 81 put on the queue head: when the caller's column order already matches the table's, the normalized `object[]` can be skipped entirely (the recorded 112 B/row on the array arm), which is P1's next item rather than a parameter tweak. + +- Verification: canary 1/1 at 900 B/row; suite 2124/0/0/0; gate PASSED.

Reading the shape showed the assumption is false for every default table: a `CREATE TABLE` without a PK gets a **hidden AUTO `_rowid` column**, and `PreparedInsertStatement` deliberately excludes internal columns from `columnOrder`. So `columnIndexMap.Length` (5) can never equal `Columns.Count` (6), the identity condition is never satisfied, and — more fundamental than that — the normalized row is **required** precisely to carry the auto-generated `_rowid` value. Aliasing would have dropped a column's value. The measured 3 B is the two inline checks; the `object[]` was never saved. + +**What was verified before reverting, and why the revert is the deliverable.** The mutation question was checked first: `InsertBatchCriticalSection` only *reads* `validatedRows` (`ValidateExistingPrimaryKeys`, `UpdatePrimaryKeyIndex`, `UpdateHashIndexes`, `RowsToDictionaries`); the in-place `row[col] = …` writes live in the dictionary normalization paths, not here. So aliasing would have been safe *from mutation* — it is the hidden AUTO column that makes it wrong, and that is the kind of thing a session can only learn by reading `Table.CRUD.cs`'s own comment about `_rowid` plus the column-count mismatch. Session 81's 112 B/row figure is not wrong; it belongs to a shape without hidden columns, and that distinction is now on the plan's refuted list so the next session does not re-derive it. + +- Verification after the revert (the tree is back to addendum 7's state): canary **1/1** at 900 B/row, full suite **2124 / 0 failed / 0 errors / 0 skipped in 85,7 s**, gate **`GATE PASSED`** (capability `raw INSERT` 0,98×, `default INSERT` 1,02×, `raw UPDATE` 0,96×, `default UPDATE` 1,03×). +- Commit: none — nothing committed or pushed. +- NEXT: (1) **P1 is at its ceiling for per-row scratch** — the remaining 894 B/row is payload (`encode` 192), engine write (191), index maintenance (38) and the normalized row the hidden `_rowid` makes mandatory. The next real lever is **P2**, the deferred-span classification for UPDATE, which is gated on a measured *timing* win against the capability baseline. (2) **P1 alternative worth one probe** — the dictionary-free INSERT path still copies twice at the `Database.InsertBatch` boundary (`rows as object[][] ?? [.. rows]`, `columns as List ??

One is mine and is fixed here: the coverage job runs the suites a second time under `dotnet-coverage collect`, and instrumentation changes what the JIT is allowed to do, so both allocation canaries stopped measuring the engine and started measuring the collector. Evidence from job 131142938452: RuntimeAsyncCodegenTests reported 71.424 bytes over 1.000 awaited calls - exactly the classic (non-runtime-async) figure, i.e. the elision is gone under instrumentation, so asserting 0 was never true there - and InsertBatchAllocationTests read 902 B/row against its 900 ceiling.

The adapter is the SQLite dialect, not the SQLite engine. CreateOptions now pairs SQLiteTools.GetDataProvider with a live SharpCoreDBConnection from SharpCoreDB.Data.Provider - linq2db generates the SQLite SQL, SharpCoreDB executes it, owns the file and applies AES-256-GCM - with bulk copy pinned to MultipleRows, GUIDs written as text instead of a blob literal, and GetUnderlyingConnection returning the SharpCoreDB connection instead of closing it to release a SQLite handle. The string constructor, CreateSharpCoreDBOptions and UseSharpCoreDB all route through that one definition. Making that work exposed seven engine defects, each a SQLite-compatibility gap and each fixed here: (1) INSERT assumed exactly one space after INSERT INTO and read the table name up to the next space, so a pretty-printed statement failed with 'Table notes](...' and INSERT/INTO across a newline threw ArgumentOutOfRangeException - one scanner now reads the token for all four INSERT parsers; (2) a SELECT list was not a projection (SELECT c, b, a returned a, b, c, aliases dropped, cached point lookups skipped it), so every ordinal-mapping consumer read the wrong column; (3) WHERE [t].[col] and WHERE NOT [t].[col] were not truth tests (all rows in directory mode, none in single-file); (4) LIKE ... ESCAPE matched nothing, missing from all five copies of the matcher; (5) SELECT EXISTS (SELECT ...) never reached an executor; (6) byte[]/Guid written as 0x.../X'...' literals failed as base64; (7) the reader threw 'Invalid read position' when a column type was asked for before the first Read(). Also: UPDATE SET [col] no longer drops the assignment silently, and the functional SQL translator now selects the columns its IS SOME/IS NONE post-filter reads. Tests: MultilineStatementTests (6), BlobLiteralTests (3), SelectSemanticsTests (14, both storage modes), StorageTests (password honoured, no SQLite header, reopens through the core provider); the linq2db fixture issues one statement per command and one culture-dependent functional test now formats invariantly. Verified: red before / green after on the parser fix, core 2149, linq2db 25, EF Core 116, Functional 38, Dapper 3, SharpCoreDB.CI.slnf build clean; the SingleFileDirectoryParityTests canary caught a BETWEEN group-numbering regression during the work and is green.

The adapter is the SQLite *dialect*, not the SQLite *engine*: `SharpCoreDBDataConnection.CreateOptions` now pairs `SQLiteTools.GetDataProvider(...)` with a live `SharpCoreDBConnection`, so linq2db generates SQLite SQL and SharpCoreDB executes it, owns the file and applies its AES-256-GCM encryption; bulk copy is set to `MultipleRows` so the provider-specific native path is never taken, the GUID mapping writes text instead of a 16-byte blob literal, and `GetUnderlyingConnection()` returns the SharpCoreDB connection (it used to close it to release a SQLite file handle). `SharpCoreDBProviderExtensions.CreateSharpCoreDBOptions` and `Extensions.UseSharpCoreDB` route through the same definition, so the three entry points cannot drift. Pinned by `tests/SharpCoreDB.Functional.Linq2DB.Tests/StorageTests.cs` (password accepted, `SQLite format 3` header absent, the file reopens through the core provider) and by the 24 existing adapter tests, which previously ran against SQLite while using `.scdb` names. +- **SQL was layout-sensitive in the paths a SQL generator hits: a pretty-printed `INSERT` was rejected, the SELECT list was not applied, and the boolean / LIKE / EXISTS shapes linq2db emits matched nothing.** Making the adapter execute on SharpCoreDB exposed these one by one, and each is a SQLite-compatibility defect in its own right: (1) `ExecuteInsert` assumed exactly one space after `INSERT INTO` and read the table name as "everything up to the next space", so `INSERT INTO notes\n(\n\t[id],\n\t[body]\n)\nVALUES\n(1, 'it''s a probe')` — what linq2db, DbUp, Flyway and most pretty-printers emit — failed with `Table notes]\n(\n\t[id],… does not exist` (the name ran to the first space *inside the string literal*), and `INSERT\nINTO t …` threw `ArgumentOutOfRangeException` from a `-1` slice; the same scan existed in all three INSERT parsers of the batch path, and `WHERE a=1 AND\tn=2` was one unusable token in the JOIN evaluator. One definition now reads the token (`Services/SqlIdentifierScanner.cs`: any whitespace, `[…]`/`"…"`/backtick quoting, `INSERT OR REPLACE INTO`, quoted column lists) and every copy uses it. (2) A SELECT list was ignored — `SELECT c, b, a` returned `a, b, c` from the table scan, `SELECT name` returned `id` too, `AS` aliases were dropped and a cached point-lookup skipped the projection entirely — so an ADO.NET consumer that maps by ordinal read the wrong column (linq2db failed with *"The input string 'Test User' was not in a correct format"* while mapping `name` as an INT). The list is now applied on both the scan and the cached-plan path, with qualified `t.col` resolving to the single-table row's own key. (3) `WHERE [t].[is_active]` (a bare boolean column) returned **every** row in directory mode and **none** in single-file mode, and `WHERE NOT [t].[is_active]` matched none: both are SQLite truth tests and are now evaluated as such in both engines (`Services/SqlBooleanValue.cs`), on the whole condition only, so the `AND` inside `BETWEEN 10 AND 16` keeps its meaning. (4) `LIKE … ESCAPE '~'` — linq2db's rendering of `string.StartsWith` — matched nothing: the clause was not implemented in any of the five copies of the LIKE matcher, which are now one (`Services/SqlLikePattern.cs`). (5) `SELECT EXISTS (SELECT …)` — linq2db's `Any()`/`Exists()` — never reached an executor (the AST parser read `EXISTS(` as a function call and rejected the `*`); the scalar form is answered with `1`/`0`. Pinned by `SelectSemanticsTests` (14 cases, both storage modes), `MultilineStatementTests` (6) and `BlobLiteralTests` (3), and by the adapter suite (25/25) and the core suite (2.133/2.133). +- **A `byte[]` or `Guid` written as SQL could not be stored: only base64 was accepted, and a hex literal failed with *"not a valid Base-64 string"*.** SQL has three textual blob forms and generators pick different ones — SharpCoreDB's own parameter renderer writes base64, SQLite's hex blob literal is `X'0102'`, and linq2db's SQLite dialect writes `0x0102` (and `0x…` for a `Guid`). `DataType.Blob` accepted only base64 and `DataType.Guid` only the textual `Guid.Parse` forms, so an INSERT generated from a bound `byte[]` property failed outright. Both now accept all three forms (`ParseBlobValue` / `ParseGuidValue`), with the 16-byte blob read back in .NET's byte order. Pinned by `BlobLiteralTests`. +- **The ADO.NET reader threw `InvalidOperationException: Invalid read position` when a consumer asked for a column's type before the first `Read()`.** `GetDataTypeName` and `GetFieldType` read the current row's value; linq2db builds its row mapper before reading (that is how `Any()`/`Exists()` failed after the SQL was answered), and any consumer doing the same tripped over it. Both now infer the type from the result set when no row is current, and keep the O(1) current-row answer while one is. +- **Functional SQL's `IS SOME` / `IS NONE` / `MATCH` filters depended on columns the statement never selected.** The translator removes those predicates from the SQL and enforces them in the functional post-filter, which reads the columns from the returned row — so it only worked because the engine ignored SELECT lists and returned every column. With a real projection (`SELECT Id, Name, Email OPTIONALLY FROM Users WHERE Email IS SOME AND ManagerId IS NONE`), `ManagerId` was absent, the "is NONE" test treated a missing column as null and **every** row passed. The translator now appends the filter columns to the projection when they are not selected (a wildcard needs nothing; a `DISTINCT` projection is left alone rather than change its meaning). Caught by `SharpCoreDB.Functional.Tests` (38/38). - **A surplus value in a batched `INSERT … VALUES` is rejected instead of silently dropped — the last copy of the known-issue-7 truncation.** The prepared-insert fast path, the one `ExecuteBatchSQL` uses for bulk inserts, stopped counting a tuple at the table's column count: `INSERT INTO docs VALUES (1, 'a', 0,5, 21)` against a three-column table bound the first three values, discarded the rest and **succeeded**, where the statement path has rejected that shape since `[2.1.2]`. Both paths now throw, and the message names the table, the tuple and both counts; a *short* tuple keeps its documented meaning (the missing columns fall to `NULL`). Found by `tests/SharpCoreDB.Tests/PreparedInsertValuesParsingTests.cs`, which parses every case through **both** prepared parsers and asserts they agree — nothing covered either one before, which is how the two could drift. Verified on this tree: core **2118 / 0 failed**, and the §7 reproduction published in `docs/sharpcoredb-known-issues.md` still prints the fixed output for all five bound-value shapes. ### Changed diff --git a/docs/manual/providers.md b/docs/manual/providers.md index 1230a5b1..1b726e06 100644 --- a/docs/manual/providers.md +++ b/docs/manual/providers.md @@ -47,7 +47,7 @@ Guide: [`docs/graphrag/EF_CORE_COMPLETE_GUIDE.md`](../graphrag/EF_CORE_COMPLETE_ |---------|---------|-----------| | `SharpCoreDB.Functional.Dapper` | Dapper | `Option`, `Fin`, `Seq` results | | `SharpCoreDB.Functional.EntityFrameworkCore` | EF Core | functional composition over `IQueryable` | -| `SharpCoreDB.Functional.Linq2DB` | linq2db | `BulkCopyAsync` batching, full type mapping (ULID/GUID/DateTime), compile-safe LINQ — ideal for high-throughput AI/agentic workloads | +| `SharpCoreDB.Functional.Linq2DB` | linq2db | `BulkCopyAsync` batching, full type mapping (ULID/GUID/DateTime), compile-safe LINQ — ideal for high-throughput AI/agentic workloads. linq2db's SQLite dialect generates the SQL; the connection, the storage and the encryption are SharpCoreDB's | ```csharp // linq2db functional example diff --git a/src/SharpCoreDB.Data.Provider/SharpCoreDBDataReader.cs b/src/SharpCoreDB.Data.Provider/SharpCoreDBDataReader.cs index 8554c150..286f4372 100644 --- a/src/SharpCoreDB.Data.Provider/SharpCoreDBDataReader.cs +++ b/src/SharpCoreDB.Data.Provider/SharpCoreDBDataReader.cs @@ -150,12 +150,13 @@ public override long GetChars(int ordinal, long dataOffset, char[]? buffer, int /// /// Gets the name of the source data type. + /// + /// It must not read the current row: linq2db (and other consumers) ask for the type name while building the + /// row mapper, before the first , and reading a value there threw + /// InvalidOperationException: Invalid read position. + /// /// - public override string GetDataTypeName(int ordinal) - { - var value = GetValue(ordinal); - return value?.GetType().Name ??

Each package's PackageReleaseNotes gains a 2.1.3 summary and keeps the 2.1.2/2.1.1/2.1.0 history after it. Docs: CHANGELOG [Unreleased] closed into [2.1.3] - 2026-11-12 with the four Fixed entries and the Added entries; README current-release banner, release table, install list and a new What's new in v2.1.3 section (2.1.2 demoted to previous, 2.1.0 to earlier); src/SharpCoreDB/NuGet.README.md title, current-version line, footer and a What's New in 2.1.3 section; docs/PROJECT_STATUS.md version, status, current-release paragraph and the GA section (the Aspire 13.6.4 blocker is recorded as closed by the 13.6.5 bump); AGENTS.md line updated; 25 markdown files had their install snippets moved to 2.1.3.

The client resolved two copies inside that range - 10.2.6 through eslint 10 / @typescript-eslint / glob 13, and 9.0.9 through ts-jest -> @jest/transform -> babel-plugin-istanbul -> test-exclude -> glob 10 - and the patched version is 11.0.1. Adds "minimatch": "^11.0.1" to the existing overrides block (the same mechanism already used for protobufjs and esbuild) and regenerates the lockfile with npm install --package-lock-only, which resolves 11.0.8 and removes the nested 9.0.9 plus its nested brace-expansion/balanced-match.

Closes Dependabot alert #249. `deepmerge` (#246, low) has no patched release and stays open. + ### Added - **Opt-in C# 15 union outcomes (`SharpCoreDB.Unions`).** `QueryOutcome` (rows / not found / failure), `ExecuteOutcome` (rows affected / failure) and `TableLookup` (found / missing) ship as `union` declarations with seven `record class` case types (`src/SharpCoreDB/Net11/Unions/UnionOutcomes.cs`), so a `switch` over them is exhaustive at compile time — dropping an arm is a build error. Purely additive: `QueryResult`, `ExecuteResult` and every `ExecuteSQL` signature are byte-identical, and `BuildResult` is deliberately **not** retrofitted (that would break a shipped type; it stays a `record` hierarchy). Unions are structs and case values box into `IUnion.Value`, so both pattern matching and generic inspection work. Tests: `tests/SharpCoreDB.Tests/Net11/UnionOutcomeTests.cs` — 3/3, with no discard arm in any switch, which is what makes exhaustiveness a compiler guarantee rather than a runtime assertion. From 03a18745fd674103a559cd03eeac806fbf303e12 Mon Sep 17 00:00:00 2001 From: MPCoreDeveloper Date: Thu, 12 Nov 2026 22:12:37 +0100 Subject: [PATCH 13/13] test(allocation): give the InsertBatch canary each platform's measured ceiling The canary recorded 894 B/row on win-x64 (GA 11.0.100) and a single 900 B/row ceiling, so the first Linux and macOS runs reported the same code at 903 B/row and failed both jobs: 1.806.872 bytes on linux-x64 and 1.806.856 on osx-arm64 against 1.787.608 on win-x64. The 9 B/row delta is the runtime's accounting for identical code, not a code path. The ceiling is now per platform from its own measurement - 900 on Windows (894 measured), 915 on Unix (903 measured). That is ~1% headroom and still below the pre-hoist 919 B/row (about 928 on Unix), so reintroducing the allocation this canary was written to catch still fails on every platform. Verified on win-x64: the test passes with the new logic; the Unix figures come from the CI TRX of run 43306930953. --- .../Net11/InsertBatchAllocationTests.cs | 21 ++++++++++++------- 1 file changed, 13 insertions(+), 8 deletions(-) diff --git a/tests/SharpCoreDB.Tests/Net11/InsertBatchAllocationTests.cs b/tests/SharpCoreDB.Tests/Net11/InsertBatchAllocationTests.cs index 2cf239c7..8998335b 100644 --- a/tests/SharpCoreDB.Tests/Net11/InsertBatchAllocationTests.cs +++ b/tests/SharpCoreDB.Tests/Net11/InsertBatchAllocationTests.cs @@ -65,12 +65,17 @@ public void Dispose() public void InsertBatch_ArrayRows_AllocatesAtMostPerRow() { const int Rows = 2_000; - // Measured 2026-11-12 (GA runtime): 1.838.776 bytes for 2.000 rows = 919 B/row through the dictionary-free - // object[] + column-order overload.
