crdt 4.0.1

Dart implementation of Conflict-free Replicated Data Types (CRDTs).

4.0.1

• Fix edge case when merging remote records

4.0.0

• Migrate to Dart null safety

3.0.0

• Use milliseconds instead of microseconds for HLCs
• Allow using non-string node ids
• Allow watching for changes
• Add modified field to Record
• Add optional parameter modifiedSince to 'recordMap' to generate delta sets
• Make basic tests available to subclasses
• Move HiveCrdt project to its own repo: https://github.com/cachapa/hive_crdt

2.2.2

• Hlc: Add convenience fromDate constructor
• HiveCrdt: Fix NPE when getting a non-existing record

2.2.1

• Crdt: Fix encoder return type

2.2.0

• Crdt: Pass keys to map encoder and decoder, useful to disambiguate when parsing

2.1.1

• Crdt: Fix HLC timestamp generation for dart-web

2.1.0

• Hlc: Add const keywords to constructors wherever possible
• Crdt: Expose canonical time
• Crdt: Add convenience methods (isEmpty. length, etc.)
• Crdt: Add encoders and decoders to serialization helpers
• Crdt: Remove delta subsets using the record's HLC since it can lead to incomplete merges
• Crdt: Fix issue where canonical time wasn't being incremented on merge
• Crdt: Fix NPE when getting non-existent value
• HiveCrdt: Store record modified time
• HiveCrdt: Retrieve delta changesets based on modified times
• HiveCrdt: between() returns values instead of records
• HiveCrdt: watch() returns MapEntry instead of BoxEvent
• HiveCrdt: Fix DateTime key serialization

2.0.0

• Remove CrdtStore.
• Make Crdt abstract.
• Remove watches (they can be added in subclasses - see HiveCrdt).
• Add MapCrdt, a CRDT backed by a standard Map useful for testing or for volatile datasets.
• Add HiveCrdt as a submodule, A CRDT backed by a Hive store.

1.2.2

• Fix incrementing the HLC when merging newer records.
• Fix counter not being able to reach maximum (0xFFFF)

1.2.1

• Remove unnecessary Future in Crdt.values getter.

1.2.0

• Breaking: Crdt.get() now returns the value (or null) rather than the record. Use Crdt.getRecord() for the previous behaviour.
• API Change: Getter methods on both Crdt and Store are now synchronous.
• API Change: Crdt.Clear() now accepts purgeRecords to determine if records should be purged or marked as deleted.
• Add Crdt.watch() and Store.watch() to monitor the CRDT for changes.
• Add Crdt.isDeleted() to check if a record has been deleted.

1.1.1

• Add values getter which retrieves all values as list, excluding deleted records

1.1.0

• HLCs implement Comparable
• Support typed key and values
• Refactor CRDT and Store to replace index operators with getters and setters
• Add clear() method
• Add JSON de/serialisation helper methods

1.0.0

• Initial version
