Ioto 1.3.0 Update
I’m happy to announce the release of Ioto 1.3.0.
This release provides a good collection of bug fixes and usability improvements for Ioto and the Ioto APIs.
All users of previous Ioto versions 1.X are encouraged to update to the new version.
The major changes include:
- Improved the web server route definition and processing to specify route handlers, methods and URL prefixes.
- Improved web server request tracing.
- Enhanced support for the legacy protocol HTTP/1.0 and improved HTTP method coverage.
- Improved API usability.
- A set of bug fixes.
Unit Tests
Ioto relies on several sub-modules that provide functionality and communication protocols. These include:
- R — the safe portable runtime
- DB — the local embedded database
- JSON — JSON parser and query engine
- MQTT — MQTT protocol
- OSDEP — O/S dependency abstraction layer
- UCTX — Fiber coroutine support
- URL — HTTP client library
- WEB — HTTP web server library
Each of these modules has their own extensive unit and service test suites. Most of these modules leverage code written for the GoAhead and Appweb web servers that has been battle-hardened over many years in a diverse set of deployments. In this release, we’ve “mined” the GoAhead and Appweb unit test libraries for a large pool of unit tests and have migrated these to Ioto. These tests are run using CI/CD on every code commit.
Ioto itself also has an extensive suite of integration and service tests that are run on a variety of platforms and operating environments.
