Introduce startPdfParseOperation to encapsulate worker operation creation, job rate tracking, and parse state initialization for PDFs. Replace scattered operation setup logic in register-upload, docx-to-pdf upload, and parse-state-backfill with this unified helper. Update job enqueuing to propagate initial opId/jobId/status for accurate state tracking.
Change getParsedPdfDocument to throw on non-ready states and remove polling logic from usePdfDocument, shifting readiness detection to event streams. Switch API responses for non-ready parses from 202 to 409 to clarify client expectations and simplify error handling.
Add targeted tests to verify legacy backfill behavior and ensure no worker operation is created for pure data fetches of pending legacy PDFs.
BREAKING CHANGE: API now returns 409 Conflict for non-ready parsed PDFs instead of 202, and clients must subscribe to event streams for parse progress.
Transition document upload flow to use presigned token-based temporary uploads. Add finalize endpoint to register uploaded documents after blob transfer, decoupling document ID assignment from upload initiation. Update client and server logic to operate on tokens, improve security, and enable canonical ID reuse for identical uploads. Update tests to verify deduplication behavior.
Eliminate all code, tests, and utilities related to the legacy 'unclaimed' user
scope. All API endpoints, document and audiobook storage, and access logic now
require a valid authenticated userId and only operate on resources owned by that
user. Remove related helper functions, test cases, and conditional flows for
anonymous/unclaimed data. Update types, client APIs, and UI logic to reflect
that only 'user' scope is supported. This simplifies ownership checks and
removes ambiguity around document and audiobook access.
Integrate opId handling throughout PDF layout parsing by updating client hooks, API routes, and event streams to support operation ID propagation. Add server utility for worker operation creation to centralize opId management. Enhance polling and SSE subscription utilities to accept and return opId, improving traceability and coordination of parse operations across the client and server.
Introduce detailed progress reporting for PDF layout parsing, exposing phase and page-level updates to clients. Replace legacy parseStatus with a structured parseState field in the database schema, updating all relevant backend and API logic. Add SSE endpoint for real-time parse progress updates. Update client hooks and UI to reflect granular progress and improve user feedback during document parsing. Includes migration scripts and new parse-state utility module.
Eliminate the "none" compute mode and all related code paths, including the NoneComputeBackend, "unsupported" parse status, and PDF margin settings. Parsing is now always available if the app starts successfully, and configuration is limited to "local" or "worker" compute modes. Update types, API routes, client adapters, and documentation to reflect this simplification.
BREAKING CHANGE: "none" is no longer a valid COMPUTE_MODE; only "local" and "worker" are supported. "unsupported" parse status and PDF margin settings are removed.
Replace the previous whisper.cpp-based word alignment with a fully ONNX-based
implementation using onnxruntime-node and @huggingface/tokenizers. Add new
Whisper ONNX model management, alignment mapping, and spectral analysis modules.
Remove all code and documentation referencing whisper.cpp, update environment
variables, Dockerfile, and docs to reflect ONNX-only alignment. Add unit tests
for alignment and ONNX model logic.
Migrate PDF parsing to use ONNX Docling layout model for structured block extraction, enabling improved TTS segmentation and chaptering. Add compute backend abstraction for heavy tasks (alignment, layout parsing) with configuration via `OPENREADER_COMPUTE_MODE`. Integrate block-level locators and document settings for per-document PDF parsing options. Update S3 storage for parsed PDF JSON, add migration and schema changes, and extend client and server APIs for parsed data and settings. Remove legacy word highlight flag in favor of compute capability detection.
- Add ONNX model download, local/none compute modes, and `onnxruntime-node` dependency
- Update PDF viewer and TTS pipeline to use parsed blocks and block-level locators
- Add document settings storage and APIs for per-document PDF options
- Update S3 storage layout for parsed PDF JSON
- Add admin/config/docs updates for new compute and parsing features
- Remove obsolete word highlight runtime flag and UI
BREAKING CHANGE: PDF parsing and word highlighting now require `OPENREADER_COMPUTE_MODE=local` and ONNX model; document settings and S3 layout updated; legacy word highlight flag removed.
Integrate changelog version check on settings open, triggering the changelog
panel when a new app version is detected. Refactor user preferences storage to
support metadata via payload utilities, enabling version tracking and future
extensibility. Add API endpoint for changelog version check and related tests
for changelog and preferences payload logic.
Eliminate the deprecated `/api/tts` route and its client usage, consolidating TTS generation logic under chapter and segment endpoints. Update client API utilities to remove direct TTS buffer fetching and improve error propagation for chapter generation failures. Extend TTS segment error metadata to include upstream rate limit and retry details, and standardize error typing in shared types. Adjust tests and helpers to reflect the new TTS mocking approach and endpoint structure. This streamlines TTS API surface and enhances error reporting consistency.
Introduce configurable segment preloading depth, sentence lookahead, and TTS segment max block length for both PDF and EPUB readers. Add new settings to user preferences, config context, and document settings UI. Refactor TTS segment splitting logic to support per-user max block length and propagate these options through PDF/EPUB adapters and TTS segment generation. Update API, manifest pagination, and segment deduplication for improved performance and correctness. Add tests for new NLP options and manifest logic.
BREAKING CHANGE: TTS segment splitting and manifest APIs now require max block length and preloading parameters; user config schema updated.
Remove legacy TTS segment manifest and audio endpoints in favor of new presigned and fallback audio URL approach. Update segment manifest structure to include `audioPresignUrl` and `audioFallbackUrl` fields, deprecating the previous `audioUrl`. Refactor segment ensure logic and TTS context to utilize the new playback source model. Add server utilities for generating presigned S3 URLs and introduce new API routes for presign and fallback audio retrieval. Clean up obsolete client API functions and types to reflect the new manifest format.
Introduce TTS segment support with new database tables and migrations for both Postgres and SQLite. Implement segment ensure, audio, and manifest API endpoints, segment storage in S3, and segment authorization logic. Update TTS context and client API to use segment-based synthesis and retrieval. Add server-side helpers for segment ID, settings hash, locator normalization, and audio probing. Extend user data cleanup and teardown logic to remove TTS segment objects. Add unit tests for segment helpers.
BREAKING CHANGE: TTS synthesis now uses segment-based storage and APIs; database migrations required.
- Removed unused imports and types from TTS route.
- Consolidated TTS buffer generation logic into a new module.
- Implemented caching for TTS audio buffers using LRU cache.
- Updated TTS request handling to support instructions for specific models.
- Refactored audiobook chapter creation to use new TTS generation logic.
- Simplified error handling and response management in TTS API.
- Enhanced client-side logic to manage TTS requests and retries.
- Updated types to reflect changes in TTS request payload structure.
