Huang Xin ed8956e9ed feat(koplugin): Readest Library view in KOReader (#4056 )

* feat(koplugin/library): data layer + busted harness + design doc

- LibraryStore: per-user SQLite index merging cloud + local books by
  partial-md5 hash. listBooks/listBookshelfBooks/listBookshelfGroups,
  upsertBook with cloud_present/local_present OR-merge + _force/clear
  sentinels, parseSyncRow, getChangedBooks for tombstone push.
- EXTS table mirroring web's document.ts.
- busted harness with KOReader stubs (G_reader_settings, DataStorage,
  lua-ljsqlite3 against :memory:); spec_helper, exts_spec, smoke_spec,
  librarystore_spec covering schema, sort, group nesting, dedupe.
- Library design doc + spec README.
- pnpm test:lua wired through root + app package.json; lint-koplugin
  recurses into library/ + spec/.

* feat(koplugin/library): cloud sync — push, pull, upload, delete, downloads

- Spore methods: pullBooks (incremental /sync), getDownloadUrl,
  getUploadUrl, listFiles, deleteFile.
- syncbooks.lua: pushBook + pushChangedBooks (advances watermark to
  max(updated_at, deleted_at)), syncBooks(opts, mode) for push/pull/both,
  downloadBook + downloadCover (sync socket.http with file sink; cover
  download via fork+poll with single-slot queue + visible-page filter +
  coalesced refresh), uploadBook (presigned-PUT flow + best-effort
  cover), deleteCloudFiles (list-then-delete-each, mirrors
  cloudService.deleteBook).
- SyncAuth.withFreshToken wrapper resolves the ensureClient race; 401/403
  unified across syncconfig + syncannotations.
- Cloud + local book covers shared by partial-md5 hash; cover.png cached
  at <settings>/readest_covers/<hash>.png with sentinel for known 404s.
- syncbooks_spec covers row-to-wire conversion + file_key shape.

* feat(koplugin/library): local discovery — sidecar scanner + cover provider

- localscanner.lightScan iterates ReadHistory entries, reads
  partial_md5_checksum from .sdr sidecars, and upserts local rows.
  Slow filesystem walks deferred to fullSidecarWalk (24h-gated).
- coverprovider wraps BookInfoManager:getBookInfo for local books with
  graceful FakeCover fallback when coverbrowser is absent.
- localscanner_spec + coverprovider_spec.

* feat(koplugin/library): UI — widget, item, view menu, FileManager hooks

- librarywidget: full-screen Menu mixed in with CoverMenu + Mosaic/List
  per zen_ui's group_view pattern. Title-bar tap → view menu, search via
  left icon, drill-in/back for grouping. Async cloud sync deferred via
  scheduleIn so the menu paints before HTTP fires.
- libraryitem: BIM patch for cloud-only (readest-cloud://) and group
  (readest-group://) URIs; group-cover composer (2x2 mosaic for grid,
  same in list) with cache key derived from the actual first-N hashes
  for content-based invalidation; ListMenuItem update + paintTo patches
  for wider list-mode cover strip and cloud-up/down icon overlay.
- libraryviewmenu: ButtonDialog with View/Group by/Sort by/Actions.
  Default Group by = Groups (parity with web), values authors/groups.
- librarypaint: partial-page e-ink repaint shim adapted from zen_ui.
- main.lua: Library menu entry, dispatcher actions (Open Library / Push
  / Pull as general; progress + annotations as reader-only),
  "Add to Readest" button in FileManager's long-press file dialog
  (dedupe by partial_md5; bumps updated_at when present, inserts a
  fresh local-only row otherwise; un-tombstones via _clear_fields).
  Push books on Library open when auto_sync is on, pull-only otherwise.
- Long-press action sheet with Readest BookDetailView parity:
  Remove from Cloud & Device / Cloud Only / Device Only,
  Upload to Cloud, Download Book / Cover / All.
- Cloud-down + cloud-up SVG icons (LiaCloudDownloadAltSolid /
  LiaCloudUploadAltSolid) painted in the right-side wpageinfo slot.
- i18n catalog updated for new strings.

* refactor(koplugin/library): split libraryitem into focused modules

libraryitem.lua had grown to 1018 lines mixing five unrelated
concerns. Split along the natural seams:

  cloud_covers — readest-cloud:// URI scheme, on-disk <hash>.png
                 cache, single-slot async download queue, visible-page
                 filter
  group_covers — readest-group:// URI scheme, 2x2 mosaic composer with
                 content-derived cache key (first-N hashes), cell
                 layout table
  cloud_icons  — bundled cloud-up/cloud-down SVG loader, IconWidget
                 cache, paint-overlay positioning
  list_strip   — list-mode group row builder (4-cover wider strip
                 replacing ListMenu's square cover slot)
  bim_patch    — BookInfoManager:getBookInfo router (cloud / group /
                 local) + ListMenuItem update + paintTo patches; owns
                 the _library_local_paths set and orig BIM reference

libraryitem.lua is now 141 lines: just the entry-table constructors
(entry_from_row, entry_from_group, entry_back) plus thin install /
set_visible_hashes delegates. Each new module is 88-216 lines.

No behavior change — same 113 specs pass.

* chore(koplugin): co-locate dev tooling, ship-zip exclusions, CI job split

- apps/readest.koplugin/scripts/build-koplugin.mjs: local sideloading
  build with the same exclusions the release workflow uses.
- Move lint-koplugin + test-koplugin from apps/readest-app/scripts/ to
  apps/readest.koplugin/scripts/. All koplugin dev tooling now lives
  with the koplugin and is excluded from the published release zip.
- Rename to .mjs so Node treats them as ESM without the reparse warning
  (the i18n CommonJS scripts stay .js).
- Release workflow: zip -r exclusions for scripts/, docs/, spec/,
  .busted so dev artifacts don't ship to end users.
- PR workflow: split build_web_app into build_web_app + test_web_app
  for parallelism. The test job installs luarocks + busted +
  lsqlite3complete and runs pnpm test:lua. test-koplugin.mjs now
  hard-fails (instead of soft-skipping) when CI=true and a tool is
  missing — a broken CI toolchain previously exited 0 silently.

readest.koplugin tests

Unit tests for apps/readest.koplugin/library/ modules. Runs under LuaJIT 2.1 (the runtime KOReader uses) via busted.

Toolchain

One-time per machine:

# macOS
brew install luajit luarocks

# Linux (Debian/Ubuntu)
sudo apt-get install luajit luarocks

# Then, regardless of OS:
luarocks --lua-version=5.1 install busted
luarocks --lua-version=5.1 install lsqlite3complete

The --lua-version=5.1 flag is required: LuaJIT identifies itself as Lua 5.1, and we install rocks against that runtime so production code (which targets LuaJIT) and test code share a Lua interpreter.

Running

From the repo root:

pnpm test:lua

Or from this directory:

eval "$(luarocks --lua-version=5.1 path)"
busted --lua=$(which luajit)

Layout

spec/
├── spec_helper.lua      # KOReader stubs + lua-ljsqlite3 shim (loaded once)
├── library/
│   ├── smoke_spec.lua   # Sanity check that the harness boots
│   └── *_spec.lua       # One per module under library/
└── README.md            # This file

What `spec_helper` provides

require("lua-ljsqlite3/init") → returns a SQLite shim wrapping lsqlite3complete. Exposes the subset of the lua-ljsqlite3 API our library modules use (open, exec, prepare, bind1, step, reset, clearbind, close, etc).
require("logger") → no-op logger (warn/info/dbg/err callable).
require("datastorage") → fake DataStorage:getSettingsDir() returning a per-test mktemp -d path.
require("device") → stub Device.canUseWAL() == true, Device.screen with getWidth/getHeight.
G_reader_settings (global) → in-memory readSetting/saveSetting/flush.

Each spec calls require("spec_helper").reset() in before_each to wipe state.

Adding a new module

Write production code at apps/readest.koplugin/library/foo.lua.
Write apps/readest.koplugin/spec/library/foo_spec.lua.
Run pnpm test:lua from the repo root.
Run pnpm lint:lua to syntax-check (LuaJIT bytecode compile).

Why LuaJIT and not stock Lua?

KOReader runs LuaJIT exclusively. LuaJIT extends Lua 5.1 with FFI and a few syntax tweaks; stock Lua 5.4 has features (integer division //, bit operators ~, <const> annotations) that LuaJIT rejects. Running tests under LuaJIT catches these incompatibilities at test time instead of when KOReader fails to load the plugin.
