Waking the device with a book already open now pulls progress, annotations and stats like reopening the book does, instead of requiring a manual sync or book reopen. The pull is delayed 1s so Wi-Fi can come back up after wake (same delay upstream kosync uses on resume), debounced against rapid Suspend/Resume pairs (Android fires them on focus changes), and the pending task is dropped on widget close so it cannot run against a torn-down ReaderUI. Closes #4924 Co-authored-by: Claude Fable 5 <noreply@anthropic.com>
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)

What spec_helper provides
require("lua-ljsqlite3/init")→ returns a SQLite shim wrappinglsqlite3complete. 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/errcallable).require("datastorage")→ fakeDataStorage:getSettingsDir()returning a per-testmktemp -dpath.require("device")→ stubDevice.canUseWAL() == true,Device.screenwithgetWidth/getHeight.G_reader_settings(global) → in-memoryreadSetting/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:luafrom the repo root. - Run
pnpm lint:luato 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.
