Mongoose 7.1

Overview

This is a bugfix and cleanup release after the major version 7.0 release. A significant number of small issues were fixed, and some new examples added.

• Continuous integration test switched from CircleCI to Github Actions
• Added socks5 example
• Added esp32 example
• Added esp8266 example
• Added mingw test
• Added mbedtls test
• Added openssl test
• Added reverse proxy example
• Added proxy client example

• Fixed DNS resolution timeout
• Added SSI to mg_http_serve_dir()
• Fixed file descriptor leak for local cache codepath

Mongoose 7.0

Overview

This is a major release, aimed primarily at refactoring and cleanup of the codebase. The main focus is made on the embedded usage.
The documentation has been fully revamped, and published at https://cesanta.com/docs. Porting from the 6.x version is not straightforward, despite all concepts stayed intact. The major changes include:

• CGI support has been removed

• WebDAV support has been removed

• Socks5 support has been factored to the example

• Digest auth support has been removed. The anticipated usage is Basic + TLS

• Mongoose documentation

Non-amalgamated sources

The non-amalgamated sources are kept in src/, and amalgamation is performed by Makefile. Set -DMG_ENABLE_LINES compiler option to enable non-amalgamated diagnostics.

CI tests and coverage

A Circle CI tests are established, to test on the common platforms and compilers, for both ISO C and ISO C++ mode. Also, an automatic test coverage tracking is performed.

• Mongoose CI tests
• Mongoose test coverage

The plan for the next releases is to add platform-specific examples (like for ESP32, STM32, etc) and integrate them into CI, to ensure they do not break as development continues.

Continuous fuzzing test

Mongoose is integrated into Google's https://oss-fuzz.com/ service, to enable continuous fuzzing code tests. This helps to find security issues early on.
