From 9536158f58144916f539db0d3f3043af841b34b7 Mon Sep 17 00:00:00 2001 From: Connor Johnstone Date: Sat, 30 Aug 2025 20:23:48 -0400 Subject: [PATCH] Clean up debug logs and add comprehensive documentation for this_and_future logic MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit improves code maintainability by: 1. **Removing excessive debug logging**: - Cleaned up verbose datetime parsing and CalDAV operation logs - Kept essential error logging and status messages - Simplified request flow logging for better readability 2. **Adding comprehensive documentation**: - Detailed RFC 5545 compliant series splitting explanation - Clear operation overview with real-world examples - Frontend/backend interaction documentation - CalDAV operation sequencing and race condition prevention - Error handling and parameter validation details The documentation explains how "this and future events" works: - **Backend**: Creates comprehensive function-level docs with examples - **Frontend**: Explains the user interaction flow and technical implementation - **Integration**: Documents the atomic request handling and parameter passing This makes the codebase more maintainable and helps future developers understand the complex recurring event modification logic. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- backend/src/calendar.rs | 41 ++------ backend/src/handlers/series.rs | 137 +++++++++++---------------- frontend/src/components/week_view.rs | 51 ++++++++-- 3 files changed, 106 insertions(+), 123 deletions(-) diff --git a/backend/src/calendar.rs b/backend/src/calendar.rs index f5e9b51..6c6cecc 100644 --- a/backend/src/calendar.rs +++ b/backend/src/calendar.rs @@ -1,7 +1,6 @@ use chrono::{DateTime, Utc};
