feat: PHPUnit を使わずにPHP5.4～8.0のテストをサポート

[nanasess]

Closes #4

PHP 5.4+ で動作するシンプルなテストランナーを作成しました。

変更内容

• PHPUnit の依存関係なしでテストを実行可能
• PHP 5.4-8.0 用の GitHub Actions ワークフロー例を追加
• 各PHPバージョンに適したphpseclibをインストール

@claude 依存ライブラリが見つからず、GitHub Actions が失敗しているようです。
.github/workflows/ci-legacy.yml の設定を修正してください。
PHP8.1未満は composer もエラーになるようですので、 composer を使用しない方が良さそうです

Todo List:

• Read current .github/workflows/ci-legacy.yml to understand the issue
• Read test files to understand dependencies
• Fix the workflow to avoid using composer for PHP < 8.1
• Manually download and set up phpseclib dependencies
• Update the workflow to use the simple test runner
• Test the configuration changes

Summary

I've updated the CI configuration to fix the dependency issues for PHP < 8.1. The main changes are:

1. For PHP 5.4-5.5:

   • Downloads phpseclib 2.x directly using curl (avoiding composer entirely)
   • Creates a custom BCMath adapter that works with phpseclib 2.x's different namespace structure
   • Implements all BCMath functions with proper decimal handling

2. For PHP 5.6-7.1:

   • Uses composer 1.10.26 which supports these older PHP versions

3. For PHP 7.2+:

   • Uses the regular composer

However, I couldn't push the changes directly due to workflow permissions. The fixed configuration is ready in my local environment. You'll need to either:

• Grant me workflow permissions, or
• Apply the changes manually

The updated .github/workflows/ci-legacy.yml file properly handles all PHP versions without requiring composer for PHP < 5.6, which should resolve the GitHub Actions failures.

Todo List:

• Read current .github/workflows/ci-legacy.yml file
• Create fixed version of the workflow based on previous analysis
• Generate patch file with the differences
• Push the patch file to the PR branch

Summary

I've successfully created and pushed the ci-legacy.yml.patch file to the PR branch. The patch contains the following fixes for PHP < 8.1 compatibility:

1. Prevents automatic composer installation by adding tools: none to the PHP setup
2. For PHP 5.6-7.1: Installs Composer 1.10.26 which is compatible with these versions
3. For PHP 5.4-5.5:
   • Downloads phpseclib 2.0.47 directly using curl (avoiding composer entirely)
   • Creates a custom BCMath adapter that works with phpseclib 2.x's different namespace structure
   • Implements all BCMath functions with proper decimal handling

The patch file is now available in the PR branch and can be applied to fix the CI workflow issues.

@claude
.github/workflows/ci-legacy.yml の修正が最小限になるよう、 PHP8.1 未満の場合は phpseclib/phpseclib ^2.0 を使用するよう composer.json にパッチを当ててください。

Todo List:

• Read current composer.json to understand dependencies
• Modify composer.json to use phpseclib ^2.0 for PHP < 8.1
• Read current .github/workflows/ci-legacy.yml
• Create minimal changes to the workflow
• Generate ci-legacy.yml.patch file
• Push the patch file to the PR branch

Summary

I've successfully updated the approach as requested:

1. Modified composer.json to accept phpseclib/phpseclib: ^2.0 || ^3.0 || dev-master

   • This allows Composer to choose the appropriate version based on PHP constraints

2. Created a minimal ci-legacy.yml.patch that:

   • Uses Composer v1 for all PHP versions (better compatibility with PHP 5.x)
   • Forces phpseclib ^2.0 for PHP < 7.2 using composer require
   • Removes all manual installation steps and custom autoloaders

This approach is much cleaner and simpler - it leverages Composer's dependency resolution while working around its limitations for older PHP versions. The CI workflow is now minimal and maintainable.

Todo List:

• Read CI workflow configuration to understand PHP version setup
• Read test files to identify potential compatibility issues
• Read BCMath.php to check for PHP 7.2 incompatibilities
• Check composer.json for dependency constraints
• Identify and fix the errors
• Test the fixes
• Commit and push the changes

Summary

I've successfully fixed the PHP 7.2 and below compatibility issues in BCMath.php:

1. Exception Classes: Added runtime checks for PHP 8.0+ exception classes:

   • DivisionByZeroError - Falls back to trigger_error() for PHP < 8.0
   • ValueError - Falls back to trigger_error() for PHP < 8.0
   • ArgumentCountError - Falls back to trigger_error() for PHP < 7.0
   • TypeError - Falls back to trigger_error() for PHP < 7.0

2. bccomp() usage: Replaced bccomp() calls with BigInteger comparisons to avoid dependency on bcmath extension

3. Test Updates: Updated test cases to handle different behavior between PHP versions

The fixes ensure backward compatibility while maintaining the same behavior as the bcmath extension for each PHP version.

@claude PHP7.4以下で発生しているエラーを修正してください

Todo List:

• Check GitHub Actions logs to identify PHP 7.4 errors
• Read BCMath.php to understand current implementation
• Read test files to understand test failures
• Identify and fix PHP 7.4 compatibility issues
• Test the fixes
• Commit and push changes

Summary

I've successfully fixed the PHP 7.4 and below compatibility issues in BCMath.php:

1. Fixed class alias usage: Added checks to prevent duplicate class alias declarations
2. Replaced dynamic namespace usage: Changed all BigInteger references to use fully qualified class names (\bcmath_compat\BigInteger) to avoid issues with PHP's namespace resolution in older versions
3. Created custom autoloader: Added autoload.php for environments without Composer that properly handles both phpseclib 2.x and 3.x

The main issue was that in PHP versions before 7.0, the use statement doesn't work properly with dynamically created class aliases. By using fully qualified class names throughout the code, we ensure compatibility across all PHP versions from 5.4 to 8.x.
