State Mutation Pattern + +The codebase uses a specific pattern for state management: + +```typescript +// packages/runner/src/storage/transaction.ts:64-69 +class StorageTransaction { + static mutate(transaction: StorageTransaction, state: State) { + transaction.#state = state; + } + static use(transaction: StorageTransaction): State { + return transaction.#state; + } +} +``` + +This pattern ensures controlled state access and makes state transitions +explicit. + +### 2. Writer Isolation Enforcement + +The writer isolation is enforced at two levels: + +**Transaction Level** (`packages/runner/src/storage/transaction.ts:163-206`): + +- Caches a single writer reference in `EditableState.writer` +- Returns cached writer for same space +- Fails with `WriteIsolationError` for different space + +**Journal Level** +(`packages/runner/src/storage/transaction/journal.ts:209-232`): + +- Maintains `writers` Map but effectively allows only one +- First writer creation succeeds, stored in map +- Subsequent requests for same space return cached instance + +### 3.

Key change: StorageTransactionInconsistent errors now only occur when the underlying state has changed, maintaining the invariant that retrying after this error will see different data. This is the key indicator for when to retry a transaction. - Introduce TypeMismatchError for accessing properties on non-objects (e.g., reading string.property or null.field) - Return NotFoundError when documents or paths don't exist, instead of inconsistency errors - Fix bug where writes to nested paths of documents created in the same transaction would incorrectly fail with NotFoundError - Update all tests to expect appropriate error types - Update documentation to explain error type distinctions 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- packages/runner/src/storage/interface.ts | 42 ++-- .../src/storage/transaction-explainer.md | 15 +- .../transaction-implementation-guide.md | 51 ++++- .../src/storage/transaction/attestation.ts | 143 ++++++------ .../src/storage/transaction/chronicle.ts | 72 ++++++- packages/runner/test/attestation.test.ts | 101 ++++----- packages/runner/test/chronicle.test.ts | 22 +- packages/runner/test/journal.test.ts | 4 +- .../runner/test/transaction-notfound.test.ts | 204 ++++++++++++++++++ packages/runner/test/transaction.test.ts | 20 +- 10 files changed, 493 insertions(+), 181 deletions(-) create mode 100644 packages/runner/test/transaction-notfound.test.ts diff --git a/packages/runner/src/storage/interface.ts b/packages/runner/src/storage/interface.ts index 31a1242e4..68ff92f4a 100644 --- a/packages/runner/src/storage/interface.ts +++ b/packages/runner/src/storage/interface.ts @@ -657,6 +657,7 @@ export type CommitError = export interface INotFoundError extends Error { name: "NotFoundError"; path?: MemoryAddressPathComponent[]; + from(space: MemorySpace): INotFoundError; } /** @@ -682,13 +683,15 @@ export type ReadError = | INotFoundError | InactiveTransactionError | IInvalidDataURIError - | IUnsupportedMediaTypeError; + | IUnsupportedMediaTypeError + | ITypeMismatchError; export type WriteError = | INotFoundError | IUnsupportedMediaTypeError | InactiveTransactionError - | IReadOnlyAddressError; + | IReadOnlyAddressError + | ITypeMismatchError; export type ReaderError = InactiveTransactionError; @@ -700,19 +703,6 @@ export type WriterError = export interface IStorageTransactionComplete extends Error { name: "StorageTransactionCompleteError"; } -export interface INotFoundError extends Error { - name: "NotFoundError"; - - /** - * Source in which address could not be resolved. - */ - source: IAttestation; - - /** - * Address that we could not resolve. - */ - address: IMemoryAddress; -} /** * Represents adddress within the memory space which is like pointer inside the @@ -859,6 +849,28 @@ export interface IReadOnlyAddressError extends Error { from(space: MemorySpace): IReadOnlyAddressError; } +/** + * Error returned when attempting to access a property on a non-object value. + * This is different from NotFound (document doesn't exist) and Inconsistency + * (state changed).

charset=UTF-8 Content-Transfer-Encoding: 8bit The transaction shim's readOrThrow and writeOrThrow methods now treat TypeMismatchError like NotFoundError, returning undefined instead of throwing. This maintains backwards compatibility while leveraging the new distinct error types. Key changes: - validateParentPath now returns TypeMismatchError for type mismatches - readOrThrow returns undefined for both NotFoundError and TypeMismatchError - writeOrThrow handles both error types when creating parent entries - Updated tests to expect the correct error types 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- .../runner/src/storage/transaction-shim.ts | 66 +++++++++++++++---- .../test/storage-transaction-shim.test.ts | 12 ++-- 2 files changed, 61 insertions(+), 17 deletions(-) diff --git a/packages/runner/src/storage/transaction-shim.ts b/packages/runner/src/storage/transaction-shim.ts index 9f8680d9c..f02ebbf08 100644 --- a/packages/runner/src/storage/transaction-shim.ts +++ b/packages/runner/src/storage/transaction-shim.ts @@ -18,6 +18,7 @@ import type { ITransactionJournal, ITransactionReader, ITransactionWriter, + ITypeMismatchError, IUnsupportedMediaTypeError, JSONValue, MemoryAddressPathComponent, @@ -57,7 +58,7 @@ export function uriToEntityId(uri: string): EntityId { function validateParentPath( value: any, path: readonly MemoryAddressPathComponent[], -): INotFoundError | null { +): INotFoundError | ITypeMismatchError | null { const pathLength = path.length; if (pathLength === 0) { @@ -66,13 +67,22 @@ function validateParentPath( // Check if the document itself exists and is an object for first-level writes if (pathLength === 1) { - if (value === undefined || !isRecord(value)) { + if (value === undefined) { const pathError: INotFoundError = new Error( - `Cannot access path [${String(path[0])}] - document is not a record`, + `Cannot access path [${String(path[0])}] - document does not exist`, ) as INotFoundError; pathError.name = "NotFoundError"; return pathError; } + if (!isRecord(value)) { + const typeError: ITypeMismatchError = new Error( + `Cannot access path [${String(path[0])}] - document is not a record`, + ) as ITypeMismatchError; + typeError.name = "TypeMismatchError"; + typeError.address = { id: "of:unknown", type: "application/json", path }; // Address will be filled in by caller + typeError.actualType = typeof value; + return typeError; + } return null; } @@ -83,19 +93,25 @@ function validateParentPath( let parentIndex = 0; for (parentIndex = 0; parentIndex < lastIndex; parentIndex++) { if (!isRecord(parentValue)) { - parentValue = undefined; - break; + // Found a non-record in the path + const typeError: ITypeMismatchError = new Error( + `Cannot access path [${path.join(", ")}] - [${ + path.slice(0, parentIndex + 1).join(", ") + }] is not a record`, + ) as ITypeMismatchError; + typeError.name = "TypeMismatchError"; + typeError.address = { id: "of:unknown", type: "application/json", path: path.slice(0, parentIndex + 1) }; + typeError.actualType = parentValue === null ?
