klarna/erlavro

This system is an Erlang library for handling Apache Avro data serialization and schema management. It provides core capabilities for encoding and decoding data in both binary and JSON formats, alongside parsing Avro IDL files and managing schema definitions. The project includes tooling for code coverage analysis and comprehensive test fixtures to ensure interoperability and correctness.

This change introduces the foundational build and configuration files for the Erlang Avro library. It adds a Makefile to standardize build tasks (compile, test, dialyzer) using rebar3, configures the project with rebar.config (including the snappyer dependency and jsone for testing), and sets up code style enforcement via elvis.config. Additionally, it establishes the CI pipeline with .travis.yml, defines the Apache 2.0 license in LICENSE, and configures version control with .gitignore.

(repo-wide) · high confidence

The library is now available in the src directory, providing core Avro schema handling, binary and JSON encoding/decoding, and support for complex types including records, arrays, maps, enums, fixed, and unions. It includes an Avro IDL parser for converting .avdl files to schemas, a schema store for managing type definitions, and utilities for CRC64 fingerprinting and schema compatibility checks.

src · high confidence

The library now exposes a new \include/avro\_internal.hrl\ header alongside \erlavro.hrl\ to centralize Avro schema definitions. This change introduces specific record types for all Avro data structures (primitives, records, arrays, maps, enums, unions, and fixed types) and provides macros to validate these types. It also defines the \avro\_value\ record used to wrap encoded data (distinguishing between JSON and binary serialization) and introduces a \decoder\_hook\_fun\ type, allowing users to implement custom decoding logic for specific types.

include · high confidence

Added a new \cover-print-not-covered-lines.escript\ tool that analyzes Erlang cover data files to report specific line numbers that were not executed during testing. This script helps developers identify gaps in test coverage by importing cover data, filtering out suite modules, and printing the source lines for any uncovered code.

scripts · high confidence

Added Avro test data fixtures and generation scripts; Expanded test coverage for Avro schema types and encoders.
