This keeps the port +boundary clean while the public API remains ergonomic. + +For `Uint8Array` and `string` inputs, the size and mime metadata can still be +inferred synchronously before streaming. For true streaming inputs, callers +should provide `size` in the metadata options if they know it. + +### D3 — `InMemoryBlobStorageAdapter` + +A new infrastructure adapter implementing `BlobStoragePort` with `Map`-based +storage. No CDC chunking — it stores and retrieves content directly. Its purpose +is port conformance, not chunking behavior. + +This adapter is used by: + +- `InMemoryGraphAdapter`-based graphs (browser, tests) +- Any context where `@git-stunts/plumbing` is not available + +### D4 — Auto-construction of blob storage + +When `WarpRuntime.open()` receives a `persistence` adapter that has `plumbing` +(i.e., a `GitGraphAdapter`), it auto-constructs a `CasBlobAdapter` internally +if no explicit `blobStorage` was provided. This makes CAS the default without +requiring callers to manually wire it. + +When `persistence` does not have `plumbing` (i.e., `InMemoryGraphAdapter`), and +no `blobStorage` was provided, it auto-constructs an +`InMemoryBlobStorageAdapter`. + +The `blobStorage` parameter remains available for callers who want explicit +control (e.g., to provide an encryption key). + +### D5 — Public surface placement + +Content stream methods land on both `WarpApp` and `WarpCore`: + +- `getContentStream(nodeId)` → `AsyncIterable | null` +- `getEdgeContentStream(from, to, label)` → `AsyncIterable | null` + +These delegate to `WarpRuntime`, which delegates to `query.methods.js`. + +`getContent()` / `getEdgeContent()` also get exposed on `WarpApp` and +`WarpCore` (currently missing — a pre-existing gap). + +### D6 — Content metadata on streams + +`getContentMeta(nodeId)` returns `{ oid, mime, size }` without reading the +blob. Callers who want to decide between buffered and streaming reads based on +size can check metadata first: + +```javascript +const meta = await app.getContentMeta(nodeId); +if (meta && meta.size > THRESHOLD) { + for await (const chunk of app.getContentStream(nodeId)) { /* ... */ } +} else { + const buf = await app.getContent(nodeId); +} +``` + +This pattern is already supported — `getContentMeta()` exists on `WarpRuntime`. +It just needs to be surfaced on `WarpApp` / `WarpCore`. + +## Checkpoint Gates + +### Checkpoint 1 — Doctrine + +- [ ] This design doc reviewed and accepted +- [ ] OG-014 backlog item updated and marked ACTIVE +- [ ] No conflicts with OG-013 (out-of-core) or existing CAS work (B158–B164) + +### Checkpoint 2 — Spec + +- [ ] `BlobStoragePort` streaming contract tests written (red) +- [ ] `InMemoryBlobStorageAdapter` contract tests written (red) +- [ ] `CasBlobAdapter` streaming tests written (red) +- [ ] `attachContent()` streaming input tests written (red) +- [ ] `getContentStream()` / `getEdgeContentStream()` tests written (red) +- [ ] Auto-construction tests written (red) +- [ ] Legacy raw blob backward-compat tests written (red) + +### Checkpoint 3 — Semantic + +- [ ] `BlobStoragePort` updated with `storeStream()` / `retrieveStream()` +- [ ] `CasBlobAdapter` implements streaming via `git-cas` +- [ ] `InMemoryBlobStorageAdapter` created and wired +- [ ] `PatchBuilderV2` accepts streaming input +- [ ] `query.methods.js` implements `getContentStream()` / + `getEdgeContentStream()` +- [ ] `WarpRuntime.open()` auto-constructs blob storage +- [ ] Raw `writeBlob()` fallback removed from content write path +- [ ] All spec tests green +- [ ] Full test suite green (4000+ tests) +- [ ] `WarpGraph.noCoordination.test.js` passes + +### Checkpoint 4 — Surface + +- [ ] `WarpApp` and `WarpCore` expose content methods +- [ ] `index.d.ts` updated with streaming types +- [ ] `index.js` exports `InMemoryBlobStorageAdapter` +- [ ] CHANGELOG updated +- [ ] ROADMAP reconciled +- [ ] README updated if content examples exist + +## Affected Files + +### Ports + +- `src/ports/BlobStoragePort.js` — add `storeStream()`, `retrieveStream()` + +### Infrastructure + +- `src/infrastructure/adapters/CasBlobAdapter.js` — implement streaming methods +- `src/infrastructure/adapters/InMemoryBlobStorageAdapter.js` — new adapter +- `src/infrastructure/adapters/lazyCasInit.js` — no change expected + +### Domain + +- `src/domain/services/PatchBuilderV2.js` — streaming write input, + `normalizeToAsyncIterable()` call +- `src/domain/warp/query.methods.js` — `getContentStream()`, + `getEdgeContentStream()` +- `src/domain/warp/patch.methods.js` — forward blob storage (already done) +- `src/domain/WarpRuntime.js` — auto-construct blob storage in `open()` +- `src/domain/WarpApp.js` — expose content methods +- `src/domain/WarpCore.js` — expose content methods +- `src/domain/utils/streamUtils.js` — new: `normalizeToAsyncIterable()`, + `collectAsyncIterable()` + +### Tests + +- `test/unit/ports/BlobStoragePort.test.js` — streaming contract tests +- `test/unit/infrastructure/adapters/CasBlobAdapter.test.js` — streaming tests +- `test/unit/infrastructure/adapters/InMemoryBlobStorageAdapter.test.js` — new +- `test/unit/domain/services/PatchBuilderV2.content.test.js` — streaming input +- `test/unit/domain/WarpGraph.content.test.js` — streaming read tests +- `test/integration/api/content-attachment.test.js` — streaming round-trips + +### Public Surface + +- `index.js` — export `InMemoryBlobStorageAdapter` +- `index.d.ts` — streaming type declarations From 5dba666306eb4c6cc2e803082671aa8bea40ffef Mon Sep 17 00:00:00 2001 From: James Ross Date: Sat, 28 Mar 2026 22:11:27 -0700 Subject: [PATCH 02/16] test: add red-phase spec tests for OG-014 streaming CAS blob storage MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Checkpoint 2 (spec) for the streaming CAS blob storage design.

Updated all tests that constructed builders without blobStorage to inject createMockBlobStorage(). Also fixed a bug where setProperty for _content.size and _content.mime used raw metadata instead of normalizedMeta for non-streaming inputs, causing size to be null when not explicitly provided. Fixed pre-existing lint errors in defaultBlobStorage.js (require-await), streamUtils.js (require-await), CasBlobAdapter.js (return-await), and WarpRuntime.js (bare wildcard JSDoc type). --- README.md | 3 +- src/domain/WarpRuntime.js | 22 ++- src/domain/errors/WriterError.js | 1 + src/domain/services/PatchBuilderV2.js | 74 +++++++--- src/domain/utils/defaultBlobStorage.js | 139 ++++++++++++++++++ src/domain/utils/streamUtils.js | 128 ++++++++++++++++ src/domain/warp/query.methods.js | 76 ++++++++++ src/infrastructure/adapters/CasBlobAdapter.js | 124 +++++++++++++++- src/ports/BlobStoragePort.js | 23 +++ .../services/PatchBuilderV2.content.test.js | 125 ++++++++++------ .../InMemoryBlobStorageAdapter.test.js | 3 +- 11 files changed, 649 insertions(+), 69 deletions(-) create mode 100644 src/domain/utils/defaultBlobStorage.js create mode 100644 src/domain/utils/streamUtils.js diff --git a/README.md b/README.md index e6a8cce0..739da047 100644 --- a/README.md +++ b/README.md @@ -2,10 +2,9 @@ git-warp logo

charset=UTF-8 Content-Transfer-Encoding: 8bit Checkpoint 3 (semantic) for the streaming CAS blob storage design. BREAKING CHANGES: - attachContent() and attachEdgeContent() now require blob storage. Calling without blobStorage throws E_NO_BLOB_STORAGE instead of falling back to raw persistence.writeBlob(). - WarpRuntime.open() auto-constructs blob storage when none is provided: CasBlobAdapter for Git-backed persistence (has plumbing), InMemoryBlobStorageAdapter for in-memory/browser paths. - Content blob tree entries now use 040000 tree mode (CAS trees) instead of 100644 blob mode (raw Git blobs). Implementation: - BlobStoragePort: added storeStream() and retrieveStream() abstract methods for streaming I/O - InMemoryBlobStorageAdapter: new domain-local adapter (defaultBlobStorage.js) with content-addressed Map storage, streaming round-trip support - CasBlobAdapter: added storeStream() piping through git-cas store(), retrieveStream() using git-cas restoreStream() with legacy blob fallback, Buffer→Uint8Array normalization on retrieve() - PatchBuilderV2: accepts AsyncIterable/ReadableStream content input, routes streaming input to storeStream(), removes raw writeBlob fallback - query.methods.js: added getContentStream() and getEdgeContentStream() returning AsyncIterable for incremental consumption - streamUtils.js: normalizeToAsyncIterable() and isStreamingInput() domain utilities for input normalization - WarpRuntime: auto-constructs blob storage in open(), new streaming read methods auto-wired via wireWarpMethods All 5203 tests pass across 322 files. --- src/domain/WarpRuntime.js | 23 +++++++----- src/domain/services/CheckpointService.js | 2 +- src/domain/services/PatchBuilderV2.js | 5 ++- src/infrastructure/adapters/CasBlobAdapter.js | 5 ++- test/integration/api/helpers/setup.js | 4 +++ test/unit/domain/WarpGraph.content.test.js | 35 +++++++++++++++---- .../WarpRuntime.apiSurface.test.js.snap | 14 +++++++- .../domain/services/CheckpointService.test.js | 8 ++--- .../services/PatchBuilderV2.content.test.js | 8 ++--- .../TreeConstruction.determinism.test.js | 2 ++ 10 files changed, 78 insertions(+), 28 deletions(-) diff --git a/src/domain/WarpRuntime.js b/src/domain/WarpRuntime.js index cd9a3a3a..5a5fff85 100644 --- a/src/domain/WarpRuntime.js +++ b/src/domain/WarpRuntime.js @@ -42,17 +42,22 @@ const DEFAULT_ADJACENCY_CACHE_SIZE = 3; /** * Auto-constructs a BlobStoragePort when none is explicitly provided. - * Uses InMemoryBlobStorageAdapter as the domain-local default — this - * ensures content always flows through a blob storage port rather than - * falling back to raw persistence.writeBlob(). * - * For Git-backed graphs that want CDC chunking, callers should inject - * CasBlobAdapter explicitly via the blobStorage option. + * When persistence has `plumbing` (Git-backed), constructs a CasBlobAdapter + * for CDC chunking and Git-native GC reachability.

The raw `persistence.writeBlob()` fallback has been removed. `WarpRuntime.open()` auto-constructs `CasBlobAdapter` for Git-backed persistence (when `plumbing` is available) or `InMemoryBlobStorageAdapter` otherwise. +- **Content blob tree entries use tree mode** — patch commit trees and checkpoint trees now reference content blobs as `040000 tree` entries (matching CAS tree OIDs) instead of `100644 blob` entries. + ## [15.0.0] — 2026-03-28 ## [15.0.1] — 2026-03-28 diff --git a/docs/ROADMAP.md b/docs/ROADMAP.md index 8f885391..d9e4f359 100644 --- a/docs/ROADMAP.md +++ b/docs/ROADMAP.md @@ -1,8 +1,8 @@ # ROADMAP — @git-stunts/git-warp -> **Current release on `main`:** v15.0.0 -> **Next intended release:** v15.0.1 -> **Last reconciled:** 2026-03-28 (after publishing `v15.0.0` and then cleaning the npm/JSR artifact surface, packaged README links, and repo topology on `main`. `OG-010` is complete; `v15.0.1` is the release-correction patch.) +> **Current release on `main`:** v15.0.1 +> **Next intended release:** v16.0.0 +> **Last reconciled:** 2026-03-29 (OG-014 streaming CAS blob storage landed on `main`.

This was a deliberate +architectural decision: the adapter has zero infrastructure dependencies +(only `Map`, `TextEncoder`, `crypto.subtle`), so placing it in domain +follows the `defaultCodec.js` / `defaultClock.js` pattern and avoids a +domain→infrastructure import in `WarpRuntime.js`. + +### D4 — Auto-construction of blob storage +**Partially aligned.** Design said auto-construct based on +`persistence.plumbing`. Implementation does this, but uses a dynamic +`import()` for `CasBlobAdapter` — the only domain→infrastructure bridge +in the codebase. Accepted as a pragmatic trade-off: the alternative +(requiring all callers to wire CAS explicitly) contradicts the "every blob +gets chunked" invariant. + +### D5 — Public surface placement +**Aligned.** Content methods on both `WarpApp` and `WarpCore`. All 8 +content read methods (buffered + streaming, node + edge, for content, +OID, and metadata) exposed. + +### D6 — Content metadata on streams +**Aligned.** `getContentMeta()` / `getEdgeContentMeta()` now exposed on +`WarpApp` and `WarpCore` (previously only on `WarpRuntime`). Callers can +check size before deciding buffered vs streaming. + +## Observed Drift + +### 1. InMemoryBlobStorageAdapter placement +**Design:** `src/infrastructure/adapters/InMemoryBlobStorageAdapter.js` +**Actual:** `src/domain/utils/defaultBlobStorage.js` +**Reason:** Deliberate architectural decision — zero infrastructure deps. +**Resolution:** Accepted. The file name and module path differ from the +design doc but the behavior is identical. + +### 2. Content anchor tree mode +**Design:** Not explicitly addressed — design focused on I/O streaming. +**Actual:** Changed `100644 blob` → `040000 tree` in both +`PatchBuilderV2.commit()` and `CheckpointService.createV5()`. +**Reason:** CAS stores content as tree objects, not blobs. Git `mktree` +rejects blob-mode entries pointing at tree OIDs. +**Resolution:** Accepted as a necessary breaking change. Follow-on: legacy +graphs with raw blob content may need a migration helper if they create +new checkpoints after upgrading. Add to ROADMAP if reports surface. + +### 3. `retrieve()` not implemented as sugar over `retrieveStream()` +**Design:** D1 said "retrieve() becomes sugar: collect retrieveStream() +into a single buffer." +**Actual:** `retrieve()` remains independent — both `CasBlobAdapter` and +`InMemoryBlobStorageAdapter` implement it directly. +**Reason:** Implementation shortcut — the independent path is simpler and +avoids an extra async iteration overhead for the common buffered case. +**Resolution:** Accepted. No functional difference for callers. + +### 4. Dynamic import for CasBlobAdapter auto-construction +**Design:** D4 said "auto-constructs CasBlobAdapter internally when +persistence has plumbing." +**Actual:** Uses `await import('../infrastructure/adapters/CasBlobAdapter.js')` +inside an async function — the only domain→infrastructure dynamic import. +**Reason:** No way to statically import from infrastructure in domain +without violating hexagonal architecture. Dynamic import in an async +factory is the least-bad option. +**Resolution:** Accepted. The bridge is isolated in one function +(`autoConstructBlobStorage`), documented, and only fires for Git-backed +persistence. + +## What Went Well + +- The dev loop (doctrine → spec → semantic → surface) worked cleanly. + Red-phase tests caught real bugs during implementation (size/mime + propagation was broken for non-streaming inputs). +- The design doc's 6 decisions mapped directly to implementation steps. +- 5203 tests passing throughout — no regressions. +- The `InMemoryBlobStorageAdapter` placement decision avoided a hexagonal + architecture violation that would have been the first in the codebase. + +## What Could Improve + +- The content anchor tree mode change (`100644 blob` → `040000 tree`) was + not anticipated in the design doc.

They always route through +`BlobStoragePort`. Without blob storage, they throw `NO_BLOB_STORAGE`. + +**Who is affected:** Only consumers who construct `PatchBuilderV2` directly +(bypassing `WarpRuntime.open()`) without passing `blobStorage`. If you use +`WarpApp.open()`, `WarpCore.open()`, or `WarpRuntime.open()`, blob storage +is auto-constructed — no code changes needed. + +**How to migrate:** + +```javascript +import InMemoryBlobStorageAdapter from '@git-stunts/git-warp/defaultBlobStorage'; + +// If you construct PatchBuilderV2 directly, add blobStorage: +const builder = new PatchBuilderV2({ + persistence, + writerId: 'alice', + blobStorage: new InMemoryBlobStorageAdapter(), // or CasBlobAdapter for Git + // ...other options +}); +``` + +## Streaming content I/O + +**What changed:** `attachContent()` and `attachEdgeContent()` now accept +streaming input (`AsyncIterable`, `ReadableStream`) +in addition to `Uint8Array` and `string`. New `getContentStream()` and +`getEdgeContentStream()` methods return `AsyncIterable`. + +**Who is affected:** No one — this is additive. Existing code continues to +work. New streaming APIs are opt-in. + +**How to use:** + +```javascript +// Streaming write — pipe a file directly +import { createReadStream } from 'node:fs'; +const patch = await app.createPatch(); +patch.addNode('doc:1'); +await patch.attachContent('doc:1', createReadStream('large-file.bin'), { + size: fileStat.size, + mime: 'application/octet-stream', +}); +await patch.commit(); + +// Streaming read — consume incrementally +const stream = await app.getContentStream('doc:1'); +if (stream) { + for await (const chunk of stream) { + process.stdout.write(chunk); + } +} + +// Buffered read — unchanged +const buf = await app.getContent('doc:1'); +``` + +## Content blob tree entries use tree mode + +**What changed:** Patch commit trees and checkpoint trees now reference +content blobs as `040000 tree` entries (CAS tree OIDs) instead of +`100644 blob` entries. + +**Who is affected:** Consumers who parse raw Git commit trees and expect +content anchor entries to use blob mode. This does not affect any public +API — it is an internal storage format change. + +**How to migrate:** If you parse `_content_` entries from commit trees, +update your parser to accept `040000 tree` mode. + +## `TraversalService` removed + +**What changed:** The `TraversalService` export was a deprecated alias for +`CommitDagTraversalService`. It has been removed. + +**How to migrate:** + +```javascript +// Before +import { TraversalService } from '@git-stunts/git-warp'; + +// After +import { CommitDagTraversalService } from '@git-stunts/git-warp'; +``` + +## `createWriter()` removed + +**What changed:** The `createWriter()` method on `WarpApp` was deprecated in +v15 and has been removed.
