deleteDirectObject method - deleteDirectManyObjects method - storeDirectMany method - Generic receiver/emitter utils (to be removed to external repo in future) - Receiver/emitter driver modes configuration * Improvements to recompute functionality:q - Do not crash on invalid object ids - Refactor to use internal emitter/receiver utils - Process 10 objects at once - Multi process recomputation - Imply external object ids resolution and getData method * Introduce lazy stamps calculations with asonchronicity support, on computed properties updates * Emit update and delete events on direct changes * Fix collection change event 'batch' type handling * Fix keyPath validation in searchDirect * Fix queueing in store methods * Ensure expected resultion of get* operations (take into account uncertain states) * Change return value of __getDirectAllObjectIds, so it returns hash of events instead of array of ids * In getDirectAllObjectIds do not return ids for not initialized objects * Introduce new name convention for driver specific methods (\_method\_) * Improve tests organisation * Unify internal conventions v0.0.12 -- 2015.12.01 * Fix `record` events dispatch v0.0.11 -- 2015.12.01 * Introduce `recompute` utilities to recalculate computed data in outer process * Introduce - getDirectAllObjectIds - getDirectObjectKeyPath - searchDirect - recalculateAllSizes * Replace recalculateDiretSize and recalculateComputedSize with recalculateSize * Rename getReducedNs to getReducedObject * Allow early return in search* methods, and make breaking record a resolution value (they work similarily to `find` now) * Unify events names and structure * Do not emit 'size' events ('reduced' events should be observed instead) * Emit 'record' events (allows registration for specific ownerId + keyPath) * Ensure all registered listeners are unbound on close * Improve handling of bogus storages in TextFile driver * Reorganise and cleanup internals v0.0.10 -- 2015.11.18 * Significant reorganisation and improvements to internal logic * Removed various race condition vulnerabilities * Implement internally write lock functionality * Rename all driver methods so they start with `__` prefixes * Make one central method for writes: `__storeRaw` * Improve methods (both public and private) naming * `indexCollection` method * `clear` method * `trackColletionSize` method * `trackMultipleSize` method * Introduce `onWriteDrain` `onWriteLockDrain` (on demand promises) * Suppport observation of object creation * Fix emit of progress events * Fix keyPaths filter handling * Bring back support for function filters * Emit size change events * Introduce error codes * Do not memoize indexes, instead crash on duplicate names * Rename 'custom' namespace to 'reduced' * Rename 'index' namespace to 'computed' * Update TextFile storage to use three different (direct, computed, reduced) buckets of data instead of one v0.0.9 -- 2015.10.25 * Automatically resolve stamps when handling custom records * Ensure updates come with new data objects * No longer rely on index map being held in memory * Introduce public getIndexedValue method * Emit old value with events * Reorganize direct events store handling, and emit events on that as well * Introduce onDrain promise * Automatic size tracker for both direct and index records * Remove `name` support from indexKeyPath (one storage should be after one object type after all) * Fixes to default driver * Fix return value type in _close * Ensure database folder is created before any operations v0.0.8 -- 2015.10.22 * Fix isObjectId resolution * Improve debug logging v0.0.7 -- 2015.10.17 * Support any observable set for indexing * Improve internal organisation * Improve events handling v0.0.6 -- 2015.10.15 * Improve operations queue handling * Improval internal methods names v0.0.5 -- 2015.10.15 * Improve tests * Reconfigure handling of computed results * Make 'close' operation safe v0.0.4 -- 2015.10.13 * Fix computed properties handling * Generalize tests v0.0.3 -- 2015.10.12 * `is` and `ensure` utils * Export raw data functionality * Fix custom keys handling * Fix storage of undefined values in TextFile driver * Fix emit of progress events on loadAll v0.0.2 -- 2015.10.02 * Update dependencies v0.0.1 -- 2015.10.02 * Initial
