…the code to follow changes in the dependencies

- Mostly Docker and docker-compose files added to help aid in testing different MySQL database versions
- Significant refactoring of PHPUnit tests, now only using one PDO connection and switching expectation file by MySQL major server version (5 or 8)

…son to be compatible with it. Adding a test-runner and DOCKER.md instructions of how to use it

- Update diff/diff from 2.0.*@dev to ~3.0 for full PHP 7.2-8.4 support
- Resolves all deprecation warnings in PHP 8.3+ environments
- Maintains backward compatibility with older PHP versions
- Tested successfully with PHP 7.4, 8.3, and 8.4 with MySQL 8.0-9.3

This change eliminates the following deprecated warnings:
- Serializable interface deprecation warnings
- ArrayObject method compatibility warnings
- Constructor parameter nullability warnings

The new version provides a clean, warning-free experience across
all supported PHP versions while maintaining full functionality.

…renamed from test-runner and reset)

…used in the Docker container (as seen in your output: PHPUnit 11.5.51). Starting with PHPUnit 10, the --verbose flag was removed in favor of more specific flags or default behavior. I have fixed this by removing the deprecated --verbose flag from both the automated start.sh script and the manual run-comprehensive-tests.sh script.

…th PHPUnit 11's strict instantiation requirements.

Missing Baselines: Identified that the commit requires a --record run first because it only included fixtures and the test logic, not the expected results.

Modern PHP (8.0+) no longer allows calling non-static methods statically. The ParamsFactory::merge() method was defined as a standard protected method but was being called using self::merge(). This worked in older PHP versions but caused a fatal error in your PHP 8.3 environment.

The Fix:
1. Static Method Migration: Updated src/Params/ParamsFactory.php to define merge() as protected static.

2. Output Buffer Reliability: Updated the test runners in DBDiffComprehensiveTest.php and End2EndTest.php to use try...finally blocks. This ensures that even if a test fails or the application hits an error, the output buffers are closed properly, which avoids the "Risky Test" warnings you saw.

I updated src/SQLGen/DiffSorter.php to include secondary (by table), tertiary (by column/key), and quaternary (by primary keys for data) sorting. This ensures that the generated SQL is always in the same order regardless of how the system/database returns the metadata.

…dTest.php, just like the new comprehensive suite has. This makes it easy to update baselines when the SQL generation logic is improved.

Comprehensive Script Update: I updated run-comprehensive-tests.sh to run all tests in the project (both the new 10 comprehensive tests and the legacy end-to-end test).

* docker/docker-entrypoint.sh: Updated to support "keep-alive" commands (like tail -f /dev/null). This allows containers to stay active in --watch mode so you can exec into them.
* src/SQLGen/DiffSorter.php: Implemented Deterministic Sorting. SQL migrations are now sorted by Table Name → Column/Key Name → Data Primary Keys. This ensures the output is identical across any machine/environment.
* tests/End2EndTest.php:
  - Future-Proofing: Removed hard-coded version checks (8.0, 9.3) in favor of dynamic major version detection.
  - PHP 8.3/PHPUnit 11 Support: Moved initialization from __construct to setUp and added output buffer safeguards (try-finally).
  - Record Mode: Added DBDIFF_RECORD_MODE support to allow syncing the legacy baseline with the new deterministic sorting order.
  - Robustness: Added database connection retry logic (3 attempts) to handle Docker startup delays.
  - Documentation: Added extensive code comments explaining the test architecture.

* Fixed fieldsToIgnore for Schema Diffs: The fieldsToIgnore configuration was previously only respected for data comparisons. I have updated src/DB/Schema/TableSchema.php to also filter out ignored columns during schema difference calculations. This ensures that changes to ignored fields won't trigger unwanted ALTER TABLE statements.
* Fixed HTML Escaping in SQL Output: The project uses Laravel's Blade component for templating. In newer versions, the default {{ $var }} syntax automatically escapes HTML entities (turning ' into '). I updated src/Templater.php to use the raw output syntax {!! $var !!} for the default template, ensuring SQL remains clean and valid.
* Refined Test Assertions: In DBDiffComprehensiveTest.php, I replaced the broad contains('UPDATE') check with a more precise regular expression. This prevents false positives when a schema change includes an ON UPDATE clause (common for timestamps).
* Future-Proof Versioning: As previously discussed, the tests now dynamically detect any major MySQL version (8, 9, 10+) and manage baselines accordingly.

1. Non-Deterministic Timestamps: The basic_schema_data fixture was using CURRENT_TIMESTAMP, causing the generated SQL to change every second. I have updated the SQL fixtures to use fixed, hardcoded timestamps (2024-01-01 00:00:00), ensuring the output is always identical.
2. Schema fieldsToIgnore Bug: Previously, ignoring fields only worked for data differences. I updated src/DB/Schema/TableSchema.php to also filter out ignored columns during schema comparisons.
3. Risky Test Warnings: In PHPUnit 11, tests that don't perform assertions (which happens during "Record Mode") are marked as "Risky." I have added manual assertion increments in record mode to satisfy PHPUnit's requirements.

…omprehensive tests was accidentally configured with a pattern that matched and deleted your recorded fixtures every time a test finished. This is why you weren't seeing any new files for Git.

Mounting Logic: My previous assertion that "nothing needs to be restarted" was correct for the code, but the basic_schema_data fixture needs a specific adjustment to ensure MySQL doesn't override our fixed dates with the current time.

…e local machine like a hard-drive and write results back to the main machine

…tests.sh and start.sh so that every test run now prints a human-readable list of each test case and its status (e.g., ✔ Schema only diff).

2. Full Issue Visibility: Enabled flags to surface all PHP warnings, notices, and deprecations directly in the terminal output. No more hidden "Deprecations: 1" messages—you'll see exactly what and where they are.
3. Modernized phpunit.xml: Updated the configuration to the modern PHPUnit 10/11 format, explicitly enabling detailed reporting for errors and deprecations.
4. Fixed Dynamic Property Deprecations: I identified that the src/Diff/ classes were using "Dynamic Properties" (assigning values to undeclared variables), which is deprecated in PHP 8.2+. I've updated all 18 classes in that directory to explicitly declare their properties ($table, $column, etc.), silencing those warnings correctly.

…h-speed restart experience.

⚡ What the --fast mode does:
  - Skip Image Deletion: It no longer deletes the Docker images between runs. Docker will reuse existing layers, cutting build time from minutes to seconds.
  - Skip Pruning: It skips the docker system prune and builder prune commands, preserving your cache for instant subsequent runs.
  - Preserve State: While it still stops and removes the active containers (to ensure code updates are applied), it does so without the heavy overhead of "wiping the slate clean."

Option 1: CLI Flag (Fastest):
  - Run with ./start.sh 8.3 8.0 --watch --fast

Option 2: Interactive Mode
  - Just run ./start.sh and it will now prompt you: Enable fast restart mode (skip heavy cleanup)? (y/N)

…b-agostic deterministic SQL ordering / sorting was implemented

… --parallel, you now get:

* Persistent Logs: Every run (even sequential) now saves its full output to tests/logs/run_ID_mysql_VERSION.log.
* Live Visibility (Sequential): While running sequentially, the output is streamed live to your terminal while being captured to the log file (using the tee command).
* The Summary Table: At the very end of the sequential run, the terminal will clear the scroll-buffer mess and present the 📊 Results Summary Table. You can see at a glance if any of the 9 combinations failed and how long they took.
* Smart Failure Reporting: If any step in the sequence fails, the script will still finish the rest (for "all" mode) but will provide those failure snippets at the very bottom so you don't have to scroll up thousands of lines.

Removed local: Converted all those variables to standard Bash variables (global scope within the script), which is the correct way for the main execution block.
Safety Checks: Added a check for total_combinations -gt 0 to prevent any future division-by-zero errors.
Command Robustness: Added better error handling around grep and file operations to ensure the script doesn't crash if a log file is momentarily missing.
