2.2.2: Fix: Filesystem Cleanup

Fix

• Filesystem cleanup check results in a warning (not an error anymore) if leftover files were discovered and cleaned up.

Improvement

• README

2.2.1: Fix

Improvements

• Fix missing drupal/drupal require from composer.json
• Development environment improvement

Add Filesystem cleanup checker

New features

• Add Public filesystem Cleanup checker. Clean up leftover files by 'Create a file in public filesystem checker'. Sometimes when a (network-based) filesystem crashes or has other problems, temporary test files start to accumulate. This checker cleans them up, and reports errors.
• Add Psalm code scanner to keep the pinger in good shape.

Refactor, tests

Improvements

• Add PhpUnit tests with max coverage.
• Apply code scanners: PHP syntax checking, phpcs (standards, PHP compatibility), phpstan
• Refactor Lando testing env
• More sophisticated debug code generation
• Strict type checking
• Turn code into classes for better testing and architecture
• Fix handful of small bugs (revealed by tests)
• Commandline php _ping.php defaults to debug mode, and reveals the debug token.
• No functional changes.

Refactor, debugging, elasticsearch

Breaking changes

• composer.json needs a different syntax - see README.

New features

• Debugging option - allows seeing time profile and statuses of individual checks
• Service exposure protection
• Time profiling
• Improved logging, Lando is supported now
• Logs slow checks
• Memcache cluster support, connection check by low-level PHP functions (faster)
• Elasticsearch support, by curl(), cluster support, advanced configurability
• Filesystem check is now split in two: create and delete
• Individual check status tracking
• For _ping.php developers there is now Lando testing env. See README.

All ping log entries are prefixed by ping:.

There are 3 types of records:
