From 7fddf2f0fcd077c809bdb67eca63dfea811121a9 Mon Sep 17 00:00:00 2001 From: Yury Pikhtarev Date: Wed, 18 Jun 2025 01:43:12 +0400 Subject: [PATCH] refactor(censor): migrate Censor class to singleton pattern - Convert TorrentPier\Censor to singleton pattern following Config class design - Add global censor() helper function for consistent API access - Replace all global $wordCensor declarations and usage across 12 files - Implement automatic reload functionality in admin panel - Add enhanced methods: isEnabled(), addWord(), getWordsCount(), reload() Files updated: - src/Legacy/Atom.php, src/Legacy/Post.php - viewforum.php, posting.php, search.php, index.php, viewtopic.php, privmsg.php - library/ajax/posts.php, library/includes/bbcode.php, library/includes/ucp/topic_watch.php - admin/admin_words.php, library/includes/init_bb.php - common.php (added global helper) - UPGRADE_GUIDE.md (documentation) Benefits: - Single instance shared across application for better performance - Memory efficient word loading only when censoring enabled - Consistent API pattern matching config() singleton - Automatic word reloading when admin updates censored words - Enhanced developer experience with new utility methods BREAKING CHANGE: None - full backward compatibility maintained. The global $wordCensor variable continues to work as before. New censor() function is the recommended approach going forward. --- UPGRADE_GUIDE.md | 104 +++++++++++++++++++++++++++ admin/admin_words.php | 2 + common.php | 13 +++- index.php | 4 +- library/ajax/posts.php | 4 +- library/includes/bbcode.php | 4 +- library/includes/init_bb.php | 4 +- library/includes/ucp/topic_watch.php | 2 +- posting.php | 4 +- privmsg.php | 10 +-- search.php | 6 +- src/Ajax.php | 4 +- src/Censor.php | 89 ++++++++++++++++++++++- src/Legacy/Atom.php | 4 +- src/Legacy/Post.php | 4 +- viewforum.php | 2 +- viewtopic.php | 10 +-- 17 files changed, 237 insertions(+), 33 deletions(-) diff --git a/UPGRADE_GUIDE.md b/UPGRADE_GUIDE.md index 98bf8ca1c..78277f13e 100644 --- a/UPGRADE_GUIDE.md +++ b/UPGRADE_GUIDE.md @@ -5,6 +5,7 @@ This guide helps you upgrade your TorrentPier installation to the latest version ## 📖 Table of Contents - [Configuration System Migration](#configuration-system-migration) +- [Censor System Migration](#censor-system-migration) - [Breaking Changes](#breaking-changes) - [Best Practices](#best-practices) @@ -85,6 +86,80 @@ if (isset(config()->bt_announce_url)) { } ``` +## 🛡️ Censor System Migration + +The word censoring system has been refactored to use a singleton pattern, similar to the Configuration system, providing better performance and consistency. + +### Quick Migration Overview + +```php +// ❌ Old way (still works, but not recommended) +global $wordCensor; +$censored = $wordCensor->censorString($text); + +// ✅ New way (recommended) +$censored = censor()->censorString($text); +``` + +### Key Censor Changes + +#### Basic Usage +```php +// Censor a string +$text = "This contains badword content"; +$censored = censor()->censorString($text); + +// Check if censoring is enabled +if (censor()->isEnabled()) { + $censored = censor()->censorString($text); +} else { + $censored = $text; +} + +// Get count of loaded censored words +$wordCount = censor()->getWordsCount(); +``` + +#### Advanced Usage +```php +// Add runtime censored words (temporary, not saved to database) +censor()->addWord('badword', '***'); +censor()->addWord('anotherbad*', 'replaced'); // Wildcards supported + +// Reload censored words from database (useful after admin updates) +censor()->reload(); + +// Check if censoring is enabled +$isEnabled = censor()->isEnabled(); +``` + +### Backward Compatibility + +The global `$wordCensor` variable is still available and works exactly as before: + +```php +// This still works - backward compatibility maintained +global $wordCensor; +$censored = $wordCensor->censorString($text); + +// But this is now preferred +$censored = censor()->censorString($text); +``` + +### Performance Benefits + +- **Single Instance**: Only one censor instance loads words from database +- **Automatic Reloading**: Words are automatically reloaded when updated in admin panel +- **Memory Efficient**: Shared instance across entire application +- **Lazy Loading**: Words only loaded when censoring is enabled + +### Admin Panel Updates + +When you update censored words in the admin panel, the system now automatically: +1.
