## Design Decisions
### 1. **Selective Calendar Import**
The application allows users to select specific Zoho calendars to import from, consolidating all events into a single Nextcloud calendar. This design choice:
The application allows users to select specific calendars to import from, consolidating all events into a single data structure. This design choice:
- **Reduces complexity** compared to bidirectional sync
- **Provides clear data flow** (Zoho → Nextcloud)
- **Provides clear data flow** (CalDAV server → Application)
- **Minimizes sync conflicts**
- **Matches user requirements** exactly
### 2. **Timezone Handling**
All events are converted to UTC internally for consistency, while preserving original timezone information:
### 2. **Multi-Approach CalDAV Strategy**
The application implements 9 different CalDAV approaches to ensure compatibility with various server implementations:
- **Standard CalDAV Methods**: REPORT, PROPFIND, GET
- **Zoho-Specific Methods**: Custom endpoints for Zoho Calendar
- **Fallback Mechanisms**: Multiple approaches ensure at least one works
- **Debugging Support**: Individual approach testing with `--approach` parameter
### 3. **CalendarEvent Structure**
The application uses a timezone-aware event structure that includes comprehensive metadata:
```rust
pub struct Event {
pub struct CalendarEvent {
pub id: String,
pub summary: String,
pub description: Option<String>,
pub start: DateTime<Utc>,
pub end: DateTime<Utc>,
pub original_timezone: Option<String>,
pub source_calendar: String,
pub location: Option<String>,
pub status: Option<String>,
pub etag: Option<String>,
// Enhanced timezone information (recently added)
pub start_tzid: Option<String>, // Timezone ID for start time
pub end_tzid: Option<String>, // Timezone ID for end time
pub original_start: Option<String>, // Original datetime string from iCalendar
pub original_end: Option<String>, // Original datetime string from iCalendar
// Additional metadata
pub href: String,
pub created: Option<DateTime<Utc>>,
pub last_modified: Option<DateTime<Utc>>,
pub sequence: i32,
pub transparency: Option<String>,
pub uid: Option<String>,
pub recurrence_id: Option<DateTime<Utc>>,
}
```
### 3. **Configuration Hierarchy**
### 4. **Configuration Hierarchy**
Configuration is loaded in priority order:
1. **Command line arguments** (highest priority)
2. **User config file** (`config/config.toml`)
3. **Default config file** (`config/default.toml`)
4. **Environment variables**
5. **Hardcoded defaults** (lowest priority)

2. Parse iCalendar data into Event objects
3. Convert timestamps to UTC with timezone preservation
4. Apply event filters (duration, status, patterns)
5. Connect to Nextcloud CalDAV server
6. Create target calendar if needed
7. Upload events to Nextcloud calendar
8. Report sync statistics
1. Connect to CalDAV server and authenticate
2. Discover calendar collections using PROPFIND

- Fall back to PROPFIND with href discovery
- Fetch individual .ics files for event details
5. Parse iCalendar data into CalendarEvent objects
6. Convert timestamps to UTC with timezone preservation
7. Apply event filters (duration, status, patterns)
8. Report sync statistics and event summary
```
## Key Algorithms
### 1. **Calendar Filtering**
### 1. **Multi-Approach CalDAV Strategy**
The application implements a robust fallback system with 9 different approaches:
```rust
impl CalendarFilter {
pub fn should_import_calendar(&self, calendar_name: &str) -> bool {
// Check exact matches
if self.selected_names.contains(&calendar_name.to_string()) {
return true;
impl RealCalDavClient {
pub async fn get_events_with_approach(&self, approach: &str) -> CalDavResult<Vec<CalendarEvent>> {
match approach {
"report-simple" => self.report_simple().await,
"report-filter" => self.report_with_filter().await,
"propfind-depth" => self.propfind_with_depth().await,
"simple-propfind" => self.simple_propfind().await,
"multiget" => self.multiget_events().await,
"ical-export" => self.ical_export().await,
"zoho-export" => self.zoho_export().await,
"zoho-events-list" => self.zoho_events_list().await,
"zoho-events-direct" => self.zoho_events_direct().await,
_ => Err(CalDavError::InvalidApproach(approach.to_string())),
}
// Check regex patterns
for pattern in &self.regex_patterns {
if pattern.is_match(calendar_name) {
return true;
}
}
false
}
}
```
### 2. **Timezone Conversion**
### 2. **Individual Event Fetching**
For servers that don't support REPORT queries, the application fetches individual .ics files:
```rust
impl TimezoneHandler {
pub fn convert_to_utc(&self, dt: DateTime<FixedOffset>, timezone: &str) -> CalDavResult<DateTime<Utc>> {
let tz = self.get_timezone(timezone)?;
let local_dt = dt.with_timezone(&tz);
Ok(local_dt.with_timezone(&Utc))
}
async fn fetch_single_event(&self, event_url: &str, calendar_href: &str) -> Result<Option<CalendarEvent>> {
let response = self.client
.get(event_url)
.header("User-Agent", "caldav-sync/0.1.0")
.header("Accept", "text/calendar")
.send()
.await?;
// Parse iCalendar data and return CalendarEvent
}
```
### 3. **Event Processing**
### 3. **Multi-Status Response Parsing**
```rust
impl SyncEngine {
pub async fn sync_calendar(&mut self, calendar: &CalendarInfo) -> CalDavResult<SyncResult> {
// 1. Fetch events from Zoho
let zoho_events = self.fetch_zoho_events(calendar).await?;
async fn parse_multistatus_response(&self, xml: &str, calendar_href: &str) -> Result<Vec<CalendarEvent>> {
let mut events = Vec::new();
// 2. Filter and process events
let processed_events = self.process_events(zoho_events)?;
// 3. Upload to Nextcloud
let upload_results = self.upload_to_nextcloud(processed_events).await?;
// 4. Return sync statistics
Ok(SyncResult::from_upload_results(upload_results))
// Parse multi-status response
let mut start_pos = 0;
while let Some(response_start) = xml[start_pos..].find("<D:response>") {
// Extract href and fetch individual events
// ... parsing logic
}
Ok(events)
}
```

### 📈 **Nextcloud Event Import Development Plan**
The architecture is ready for the next major feature: **Unidirectional Event Import** from source CalDAV server (e.g., Zoho) to target server (e.g., Nextcloud).
#### **Import Architecture Overview**
```
Source Server (Zoho) ──→ Target Server (Nextcloud)
↑ ↓
Source of Truth Import Destination
```
#### **Implementation Plan (3 Phases)**
**Phase 1: Core Infrastructure (2-3 days)**
1. **Configuration Restructuring**
```rust
pub struct Config {
pub source: ServerConfig, // Source server (Zoho)
pub target: ServerConfig, // Target server (Nextcloud)
pub source_calendar: CalendarConfig,
pub target_calendar: CalendarConfig,
pub import: ImportConfig, // Import-specific settings
}
```
2. **Dual Client Support**
```rust
pub struct SyncEngine {
pub source_client: RealCalDavClient, // Source server
pub target_client: RealCalDavClient, // Target server
import_state: ImportState, // Track imported events
}
```
3. **Import State Tracking**
```rust
pub struct ImportState {
pub last_import: Option<DateTime<Utc>>,
pub imported_events: HashMap<String, String>, // source_uid → target_href
pub deleted_events: HashSet<String>, // Deleted source events
}
```
**Phase 2: Import Logic (2-3 days)**
1. **Import Pipeline Algorithm**
```rust
async fn import_events(&mut self) -> Result<ImportResult> {
// 1. Fetch source events
let source_events = self.source_client.get_events(...).await?;
// 2. Fetch target events
let target_events = self.target_client.get_events(...).await?;
// 3. Process each source event (source wins)
for source_event in source_events {
if let Some(target_href) = self.import_state.imported_events.get(&source_event.uid) {
// UPDATE: Overwrite target with source data
self.update_target_event(source_event, target_href).await?;
} else {
// CREATE: New event in target
self.create_target_event(source_event).await?;
}
}
// 4. DELETE: Remove orphaned target events
self.delete_orphaned_events(source_events, target_events).await?;
}
```
2. **Target Calendar Management**
- Validate target calendar exists before import
- Set calendar properties (color, name, timezone)
- Fail fast if target calendar is not found
- Auto-creation as future enhancement (nice-to-have)
3. **Event Transformation**
- Convert between iCalendar formats if needed
- Preserve timezone information
- Handle UID mapping for future updates
**Phase 3: CLI & User Experience (1-2 days)**
1. **Import Commands**
```bash
# Import events (dry run by default)
cargo run -- --import-events --dry-run
# Execute actual import
cargo run -- --import-events --target-calendar "Imported-Zoho-Events"
# List import status
cargo run -- --import-status
```
2. **Progress Reporting**
- Real-time import progress
- Summary statistics (created/updated/deleted)
- Error reporting and recovery
3. **Configuration Examples**
```toml
[source]
server_url = "https://caldav.zoho.com/caldav"
username = "user@zoho.com"
password = "zoho-app-password"
[target]
server_url = "https://nextcloud.example.com"
username = "nextcloud-user"
password = "nextcloud-app-password"
[source_calendar]
name = "Work Calendar"
[target_calendar]
name = "Imported-Work-Events"
create_if_missing = true
color = "#3174ad"
[import]
overwrite_existing = true # Source always wins
delete_missing = true # Remove events not in source
dry_run = false
batch_size = 50
```
#### **Key Implementation Principles**
1. **Source is Always Truth**: Source server data overwrites target
2. **Unidirectional Flow**: No bidirectional sync complexity
3. **Robust Error Handling**: Continue import even if some events fail
4. **Progress Visibility**: Clear reporting of import operations
5. **Configuration Flexibility**: Support for any CalDAV source/target
#### **Estimated Timeline**
- **Phase 1**: 2-3 days (Core infrastructure)
- **Phase 2**: 2-3 days (Import logic)
- **Phase 3**: 1-2 days (CLI & UX)
- **Total**: 5-8 days for complete implementation
#### **Success Criteria**
- Successfully import events from Zoho to Nextcloud
- Handle timezone preservation during import
- Provide clear progress reporting
- Support dry-run mode for preview
- Handle large calendars (1000+ events) efficiently
This plan provides a clear roadmap for implementing the unidirectional event import feature while maintaining the simplicity and reliability of the current codebase.

## TODO List and Status Tracking
### 🎯 Current Development Status
The CalDAV Calendar Synchronizer is **PRODUCTION READY** with recent enhancements to the `fetch_single_event` functionality and timezone handling.
### ✅ Recently Completed Tasks (Latest Development Cycle)
#### 1. **fetch_single_event Debugging and Enhancement**
- **✅ Located and analyzed the function** in `src/minicaldav_client.rs` (lines 584-645)
- **✅ Fixed critical bug**: Missing approach name for approach 5 causing potential runtime issues
- **✅ Enhanced datetime parsing**: Added support for multiple iCalendar formats:
- UTC times with 'Z' suffix (YYYYMMDDTHHMMSSZ)
- Local times without timezone (YYYYMMDDTHHMMSS)
- Date-only values (YYYYMMDD)
- **✅ Added debug logging**: Enhanced error reporting for failed datetime parsing
- **✅ Implemented iCalendar line unfolding**: Proper handling of folded long lines in iCalendar files
#### 2. **Zoho Compatibility Improvements**
- **✅ Made Zoho-compatible approach default**: Reordered approaches so Zoho-specific headers are tried first
- **✅ Enhanced HTTP headers**: Uses `Accept: text/calendar` and `User-Agent: curl/8.16.0` for optimal Zoho compatibility
#### 3. **Timezone Information Preservation**
- **✅ Enhanced CalendarEvent struct** with new timezone-aware fields:
- `start_tzid: Option<String>` - Timezone ID for start time
- `end_tzid: Option<String>` - Timezone ID for end time
- `original_start: Option<String>` - Original datetime string from iCalendar
- `original_end: Option<String>` - Original datetime string from iCalendar
- **✅ Added TZID parameter parsing**: Handles properties like `DTSTART;TZID=America/New_York:20240315T100000`
- **✅ Updated all mock event creation** to include timezone information
#### 4. **Code Quality and Testing**
- **✅ Verified compilation**: All changes compile successfully with only minor warnings
- **✅ Updated all struct implementations**: All CalendarEvent creation points updated with new fields
- **✅ Maintained backward compatibility**: Existing functionality remains intact
#### 5. **--list-events Debugging and Enhancement (Latest Development Cycle)**
- **✅ Time-range format investigation**: Analyzed and resolved the `T000000Z` vs. full time format issue in CalDAV queries
- **✅ Simplified CalDAV approaches**: Removed all 8 alternative approaches, keeping only the standard `calendar-query` method for cleaner debugging
- **✅ Removed debug event limits**: Eliminated the 3-item limitation in `parse_propfind_response()` to allow processing of all events
- **✅ Enhanced timezone display**: Added timezone information to `--list-events` output for easier debugging:
- Updated `SyncEvent` struct with `start_tzid` and `end_tzid` fields
- Modified event display in `main.rs` to show timezone IDs
- Output format: `Event Name (2024-01-15 14:00 America/New_York to 2024-01-15 15:00 America/New_York)`
- **✅ Reverted time-range format**: Changed from date-only (`%Y%m%d`) back to midnight format (`%Y%m%dT000000Z`) per user request
- **✅ Verified complete event retrieval**: Now processes and displays all events returned by the CalDAV server without artificial limitations

# Nextcloud CalDAV Import Implementation Plan
## 🚨 IMMEDIATE BUGS TO FIX
### Bug #1: Orphaned Event Deletion Not Working
**Status**: ❌ **CRITICAL** - Orphaned events are not being deleted from target calendar
**Location**: Likely in `src/nextcloud_import.rs` - `ImportEngine` cleanup logic
**Symptoms**:
- Events deleted from source calendar remain in Nextcloud target
- `strict_with_cleanup` behavior not functioning correctly
- Target calendar accumulates stale events over time
**Root Cause Analysis Needed**:
```rust
// Check these areas in the import logic:
// 1. Event comparison logic - are UIDs matching correctly?
// 2. Delete operation implementation - is HTTP DELETE being sent?
// 3. Calendar discovery - are we looking at the right target calendar?
// 4. Error handling - are delete failures being silently ignored?
```
**Investigation Steps**:
1. Add detailed logging for orphaned event detection
2. Verify event UID matching between source and target
3. Test DELETE operation directly on Nextcloud CalDAV endpoint
4. Check if ETag handling is interfering with deletions
**Expected Fix Location**: `src/nextcloud_import.rs` - `ImportEngine::import_events()` method
**🔍 Bug #1 - ACTUAL ROOT CAUSE DISCOVERED**:
- **Issue**: CalDAV query to Nextcloud target calendar is only returning 1 event when there should be 2+ events
- **Evidence**: Enhanced debugging shows `🎯 TARGET EVENTS FETCHED: 1 total events`
- **Missing Event**: "caldav test" event (Oct 31) not being detected by CalDAV query
- **Location**: `src/minicaldav_client.rs` - `get_events()` method or CalDAV query parameters
- **Next Investigation**: Add raw CalDAV response logging to see what Nextcloud is actually returning
**🔧 Bug #1 - ENHANCED DEBUGGING ADDED**:
- ✅ Added comprehensive logging for target event detection
- ✅ Added date range validation debugging
- ✅ Added special detection for "caldav test" event
- ✅ Added detailed source vs target UID comparison
- ✅ Enhanced deletion analysis with step-by-step visibility
**🎯 Bug #1 - STATUS**: Partially Fixed - Infrastructure in place, need to investigate CalDAV query issue
**🔧 ADDITIONAL FIXES COMPLETED**:
- ✅ **FIXED**: Principal URL construction error - now correctly extracts username from base URL
- ✅ **FIXED**: `--list-events --import-info` no longer shows 404 errors during calendar discovery
- ✅ **FIXED**: Warning and error handling for non-multistatus responses
- ✅ **FIXED**: Removed unused imports and cleaned up compilation warnings
- ✅ **FIXED**: Bug #1 - Multiple event parsing - Modified XML parsing loop to process ALL calendar-data elements instead of breaking after first one
- ✅ **COMPLETED**: Bug #1 - Orphaned Event Deletion - CalDAV query issue resolved, enhanced debugging added, infrastructure working correctly
---
### Bug #2: Recurring Event Import Issue
**Status**: ✅ **COMPLETED** - RRULE parser implemented and issue resolved
**Root Cause**: The `--list-events` command was not showing expanded individual occurrences of recurring events
**Location**: `src/main.rs` - event listing logic, `src/minicaldav_client.rs` - iCalendar parsing
**Resolution**: The issue was already resolved by the expansion logic in the sync process. Recurring events are properly expanded during sync and displayed with 🔄 markers.
**Key Findings**:
- Recurring events are already being expanded during the sync process in `parse_icalendar_data()`
- Individual occurrences have their recurrence cleared (as expected) but are marked with unique IDs containing "-occurrence-"
- The `--list-events` command correctly shows all expanded events with 🔄 markers for recurring instances
- Users can see multiple instances of recurring events (e.g., "Tether Sync" appearing at different dates)
**CalDAV/iCalendar Recurring Event Properties**:
According to RFC 5545, recurring events use these properties:
- **RRULE**: Defines recurrence pattern (e.g., `FREQ=WEEKLY;COUNT=10`)
- **EXDATE**: Exception dates for recurring events
- **RDATE**: Additional dates for recurrence
- **RECURRENCE-ID**: Identifies specific instances of recurring events
**Current Problem Analysis**:
```rust
// Current approach in build_calendar_event():
let event = CalendarEvent {
// ... basic properties
// ❌ MISSING: RRULE parsing and expansion
// ❌ MISSING: EXDATE handling
// ❌ MISSING: Individual occurrence generation
};
// The parser extracts RRULE but doesn't expand it:
if line.contains(':') {
let parts: Vec<&str> = line.splitn(2, ':').collect();
current_event.insert(parts[0].to_string(), parts[1].to_string()); // RRULE stored but not processed
}
```
**Correct Solution Approach**:
```rust
// Two-phase approach needed:
// Phase 1: Detect recurring events during parsing
if let Some(rrule) = properties.get("RRULE") {
// This is a recurring event
debug!("Found recurring event with RRULE: {}", rrule);
return self.expand_recurring_event(properties, calendar_href, start_date, end_date).await;
}
// Phase 2: Expand recurring events into individual occurrences
async fn expand_recurring_event(&self, properties: &HashMap<String, String>,
calendar_href: &str, start_range: DateTime<Utc>,
end_range: DateTime<Utc>) -> Result<Vec<CalendarEvent>> {
let mut occurrences = Vec::new();
let base_event = self.build_base_event(properties, calendar_href)?;
// Parse RRULE to generate occurrences within date range
if let Some(rrule) = properties.get("RRULE") {
let generated_dates = self.parse_rrule_and_generate_dates(rrule, base_event.start, base_event.end, start_range, end_range)?;
for (occurrence_start, occurrence_end) in generated_dates {
let mut occurrence = base_event.clone();
occurrence.start = occurrence_start;
occurrence.end = occurrence_end;
occurrence.recurrence_id = Some(occurrence_start);
occurrence.id = format!("{}-{}", base_event.id, occurrence_start.timestamp());
occurrence.href = format!("{}/{}-{}.ics", calendar_href, base_event.id, occurrence_start.timestamp());
occurrences.push(occurrence);
}
}
Ok(occurrences)
}
```
**Alternative Title-Based Detection**:
When RRULE parsing fails, use title duplication as fallback:
```rust
// Group events by title to detect likely recurring events
fn group_by_title(events: &[CalendarEvent]) -> HashMap<String, Vec<CalendarEvent>> {
let mut grouped: HashMap<String, Vec<CalendarEvent>> = HashMap::new();
for event in events {
let title = event.summary.to_lowercase();
grouped.entry(title).or_insert_with(Vec::new).push(event.clone());
}
// Filter for titles with multiple occurrences (likely recurring)
grouped.into_iter()
.filter(|(_, events)| events.len() > 1)
.collect()
}
```
**🎯 BUG #2 - RECURRENCE SOLUTION APPROACH CONFIRMED**:
Based on testing Zoho's CalDAV implementation, the server correctly returns RRULE strings but does **NOT** provide pre-expanded individual instances. This confirms we need to implement client-side expansion.
**Option 1: Time-Bounded Recurrence Expansion (SELECTED)**
- Parse RRULE strings from Zoho
- Expand ONLY occurrences within the sync timeframe
- Import individual instances to Nextcloud
- Preserves recurrence pattern while respecting sync boundaries
**Implementation Strategy**:
```rust
// Parse RRULE and generate occurrences within date range
async fn expand_recurring_event_timeframe(&self, properties: &HashMap<String, String>,
calendar_href: &str,
sync_start: DateTime<Utc>,
sync_end: DateTime<Utc>) -> Result<Vec<CalendarEvent>> {
let base_event = self.build_base_event(properties, calendar_href)?;
let mut occurrences = Vec::new();
if let Some(rrule) = properties.get("RRULE") {
// Parse RRULE (e.g., "FREQ=WEEKLY;BYDAY=MO;COUNT=10")
let recurrence = self.parse_rrule(rrule)?;
// Generate ONLY occurrences within sync timeframe
let generated_dates = self.expand_recurrence_within_range(
&recurrence,
base_event.start,
base_event.end,
sync_start,
sync_end
)?;
info!("🔄 Expanding recurring event: {} -> {} occurrences within timeframe",
base_event.summary, generated_dates.len());
for (occurrence_start, occurrence_end) in generated_dates {
let mut occurrence = base_event.clone();
occurrence.start = occurrence_start;
occurrence.end = occurrence_end;
occurrence.recurrence_id = Some(occurrence_start);
occurrence.id = format!("{}-{}", base_event.id, occurrence_start.timestamp());
occurrence.href = format!("{}/{}-{}.ics", calendar_href, base_event.id, occurrence_start.timestamp());
occurrences.push(occurrence);
}
}
Ok(occurrences)
}
```
**Key Benefits of Time-Bounded Approach**:
- ✅ **Efficient**: Only generates needed occurrences (no infinite expansion)
- ✅ **Sync-friendly**: Respects sync date ranges (default: past 30 days to future 30 days)
- ✅ **Complete**: All occurrences in timeframe become individual events in Nextcloud
- ✅ **Zoho Compatible**: Works with Zoho's RRULE-only approach
- ✅ **Standard**: Follows RFC 5545 recurrence rules
**Example Sync Behavior**:
```
Source (Zoho): Weekly meeting "Team Standup" (RRULE:FREQ=WEEKLY;BYDAY=MO)
Sync timeframe: Oct 10 - Dec 9, 2025
Generated occurrences to import:
- Team Standup (Oct 13, 2025)
- Team Standup (Oct 20, 2025)
- Team Standup (Oct 27, 2025)
- Team Standup (Nov 3, 2025)
- Team Standup (Nov 10, 2025)
- Team Standup (Nov 17, 2025)
- Team Standup (Nov 24, 2025)
- Team Standup (Dec 1, 2025)
- Team Standup (Dec 8, 2025)
Result: 9 individual events imported to Nextcloud
```
**Fix Implementation Steps**:
1. **Add RRULE parsing** to CalendarEvent struct in `src/minicaldav_client.rs`
2. **Implement recurrence expansion** with time-bounded generation
3. **Integrate with parsing pipeline** to detect and expand recurring events
4. **Update import logic** to handle all generated occurrences
5. **Add exception handling** for EXDATE and modified instances
**Expected Fix Location**:
- `src/minicaldav_client.rs` - enhance `parse_icalendar_data()`, add `expand_recurring_event_timeframe()`
- `src/event.rs` - add `recurrence` field to CalendarEvent struct
- `src/main.rs` - update event conversion to preserve recurrence information
**Implementation Phases**:
**Phase 1: RRULE Parsing Infrastructure**
```rust
// Add to CalendarEvent struct
pub struct CalendarEvent {
pub id: String,
pub href: String,
pub summary: String,
pub description: Option<String>,
pub start: DateTime<Utc>,
pub end: DateTime<Utc>,
pub location: Option<String>,
pub status: Option<String>,
pub recurrence: Option<RecurrenceRule>, // NEW: RRULE support
pub recurrence_id: Option<DateTime<Utc>>, // NEW: For individual instances
// ... existing fields
}
// Add RRULE parsing method
impl MiniCalDavClient {
fn parse_rrule(&self, rrule_str: &str) -> Result<RecurrenceRule, CalDavError> {
// Parse RRULE components like "FREQ=WEEKLY;BYDAY=MO;COUNT=10"
// Return structured RecurrenceRule
}
fn expand_recurrence_within_range(&self,
recurrence: &RecurrenceRule,
base_start: DateTime<Utc>,
base_end: DateTime<Utc>,
range_start: DateTime<Utc>,
range_end: DateTime<Utc>) -> Result<Vec<(DateTime<Utc>, DateTime<Utc>)>, CalDavError> {
// Generate occurrences only within the specified date range
// Handle different frequencies (DAILY, WEEKLY, MONTHLY, YEARLY)
// Apply BYDAY, BYMONTH, COUNT, UNTIL constraints
}
}
```
**Phase 2: Integration with Event Parsing**
```rust
// Modify parse_icalendar_data() to detect and expand recurring events
impl MiniCalDavClient {
pub async fn parse_icalendar_data(&self,
ical_data: &str,
calendar_href: &str,
sync_start: DateTime<Utc>,
sync_end: DateTime<Utc>) -> Result<Vec<CalendarEvent>, CalDavError> {
let mut events = Vec::new();
// Parse each VEVENT in the iCalendar data
for event_data in self.extract_vevents(ical_data) {
let properties = self.parse_event_properties(&event_data);
// Check if this is a recurring event
if properties.contains_key("RRULE") {
info!("🔄 Found recurring event: {}", properties.get("SUMMARY").unwrap_or(&"Unnamed".to_string()));
// Expand within sync timeframe
let expanded_events = self.expand_recurring_event_timeframe(
&properties, calendar_href, sync_start, sync_end
).await?;
events.extend(expanded_events);
} else {
// Regular (non-recurring) event
let event = self.build_calendar_event(&properties, calendar_href)?;
events.push(event);
}
}
Ok(events)
}
}
```
**Phase 3: Enhanced Event Conversion**
```rust
// Update main.rs to handle expanded recurring events
impl From<CalendarEvent> for Event {
fn from(calendar_event: CalendarEvent) -> Self {
Event {
id: calendar_event.id,
uid: calendar_event.id,
title: calendar_event.summary,
description: calendar_event.description,
start: calendar_event.start,
end: calendar_event.end,
location: calendar_event.location,
timezone: Some("UTC".to_string()),
recurrence: calendar_event.recurrence, // FIXED: Now preserves recurrence info
status: calendar_event.status,
created_at: Utc::now(),
updated_at: Utc::now(),
}
}
}
```
**RRULE Format Support**:
```
Supported RRULE components:
- FREQ: DAILY, WEEKLY, MONTHLY, YEARLY
- INTERVAL: N (every N days/weeks/months/years)
- COUNT: N (maximum N occurrences)
- UNTIL: date (last occurrence date)
- BYDAY: MO,TU,WE,TH,FR,SA,SU (for WEEKLY)
- BYMONTHDAY: 1-31 (for MONTHLY)
- BYMONTH: 1-12 (for YEARLY)
Example RRULEs:
- "FREQ=DAILY;COUNT=10" - Daily for 10 occurrences
- "FREQ=WEEKLY;BYDAY=MO,WE,FR" - Mon/Wed/Fri weekly
- "FREQ=MONTHLY;BYDAY=2TU" - Second Tuesday of each month
- "FREQ=YEARLY;BYMONTH=12;BYDAY=1MO" - First Monday in December
```

## 🚀 **BUG #1: ORPHANED EVENT DELETION - IN PROGRESS**
### **Status**: 🔧 **WORKING** - Enhanced debugging added, analysis in progress
### **Root Cause Analysis**:
The orphaned event deletion logic exists but has insufficient visibility into what's happening during the UID matching and deletion process.
### **Enhanced Debugging Added**:
**1. Detailed Deletion Analysis Logging** (`src/nextcloud_import.rs:743-790`):
```rust
info!("🔍 DELETION ANALYSIS:");
info!(" Target UID: '{}'", target_uid);
info!(" Target Summary: '{}'", target_event.summary);
info!(" Source UIDs count: {}", source_uids.len());
info!(" UID in source: {}", source_uids.contains(target_uid.as_str()));
info!(" Is orphaned: {}", is_orphaned);
```
**2. Comprehensive DELETE Operation Logging** (`src/minicaldav_client.rs:1364-1440`):
```rust
info!("🗑️ Attempting to delete event: {}", event_url);
info!(" Calendar URL: {}", calendar_url);
info!(" Event UID: '{}'", event_uid);
info!(" ETag: {:?}", etag);
info!("📊 DELETE response status: {} ({})", status, status_code);
```
**3. Enhanced Event Existence Checking** (`src/minicaldav_client.rs:1340-1385`):
```rust
info!("🔍 Checking if event exists: {}", event_url);
info!("📋 Event ETag: {:?}", etag);
info!("📋 Content-Type: {:?}", content_type);
```
### **Debugging Workflow**:
**Step 1: Run with enhanced logging**:
```bash
# Test with dry run to see what would be deleted
./target/release/caldav-sync --debug --import-nextcloud --dry-run --import-behavior strict_with_cleanup
# Test actual deletion (will show detailed step-by-step process)
./target/release/caldav-sync --debug --import-nextcloud --import-behavior strict_with_cleanup
```
**Step 2: Look for these key indicators in the logs**:
**🔍 DELETION ANALYSIS:**
- Shows UID matching between source and target
- Reveals if events are correctly identified as orphaned
- Lists all source UIDs for comparison
**🗑️ DELETION EXECUTION:**
- Shows the exact event URL being deleted
- Displays ETag handling
- Shows HTTP response status codes
**📊 HTTP RESPONSE ANALYSIS:**
- Detailed error categorization (401, 403, 404, 409, 412)
- Clear success/failure indicators
### **Common Issues to Look For**:
1. **UID Mismatch**: Events that should match but don't due to formatting differences
2. **ETag Conflicts**: 412 responses indicating concurrent modifications
3. **Permission Issues**: 403 responses indicating insufficient deletion rights
4. **URL Construction**: Incorrect event URLs preventing proper deletion
### **Next Debugging Steps**:
1. **Run the enhanced logging** to capture detailed deletion process
2. **Analyze the UID matching** to identify orphaned detection issues
3. **Check HTTP response codes** to pinpoint deletion failures
4. **Verify calendar permissions** if 403 errors occur
This enhanced debugging will provide complete visibility into the orphaned event deletion process and help identify the exact root cause.
---
### Debugging Commands for Investigation
```bash
# 1. List source events to see what we're working with
./target/release/caldav-sync --debug --list-events
# 2. List target events to see what's already there
./target/release/caldav-sync --debug --list-import-events
# 3. Run import with dry run to see what would be processed
./target/release/caldav-sync --debug --import-nextcloud --dry-run
# 4. Test recurring events specifically - compare list vs import
./target/release/caldav-sync --debug --list-events | grep -i "recurring\|daily\|weekly"
./target/release/caldav-sync --debug --import-nextcloud --dry-run | grep -i "recurring\|daily\|weekly"
# 5. Run with different CalDAV approaches to isolate source issues
./target/release/caldav-sync --debug --approach zoho-events-list --list-events
./target/release/caldav-sync --debug --approach zoho-export --list-events
# 6. Check calendar discovery
./target/release/caldav-sync --debug --list-calendars --import-info
# 7. Count events to identify missing ones
echo "Source events:" && ./target/release/caldav-sync --list-events | wc -l
echo "Target events:" && ./target/release/caldav-sync --list-import-events | wc -l
```
### Success Criteria for These Fixes
- [ ] **Orphaned Deletion**: Events deleted from source are properly removed from Nextcloud
- [ ] **Complete Import**: All valid source events are successfully imported
- [ ] **Clear Logging**: Detailed logs show which events are processed/skipped/failed
- [ ] **Consistent Behavior**: Same results on multiple runs with identical data
---
## Current State Analysis
### Current Code Overview
The caldavpuller project is a Rust-based CalDAV synchronization tool that currently:
- **Reads events from Zoho calendars** using multiple approaches (zoho-export, zoho-events-list, zoho-events-direct)
- **Supports basic CalDAV operations** like listing calendars and events
- **Has a solid event model** in `src/event.rs` with support for datetime, timezone, title, and other properties
- **Implements CalDAV client functionality** in `src/caldav_client.rs` and related files
- **Can already generate iCalendar format** using the `to_ical()` method
### Current Capabilities
- ✅ **Event listing**: Can read and display events from external sources
- ✅ **iCalendar generation**: Has basic iCalendar export functionality
- ✅ **CalDAV client**: Basic WebDAV operations implemented
- ✅ **Configuration**: Flexible configuration system for different CalDAV servers
### Missing Functionality for Nextcloud Import
- ❌ **PUT/POST operations**: No ability to write events to CalDAV servers
- ❌ **Calendar creation**: Cannot create new calendars on Nextcloud
- ❌ **Nextcloud-specific optimizations**: No handling for Nextcloud's CalDAV implementation specifics
- ❌ **Import workflow**: No dedicated import command or process
## Nextcloud CalDAV Architecture
Based on research of Nextcloud's CalDAV implementation (built on SabreDAV):
### Key Requirements
1. **Standard CalDAV Compliance**: Nextcloud follows RFC 4791 CalDAV specification
2. **iCalendar Format**: Requires RFC 5545 compliant iCalendar data
3. **Authentication**: Basic auth or app password authentication
4. **URL Structure**: Typically `/remote.php/dav/calendars/{user}/{calendar-name}/`
### Nextcloud-Specific Features
- **SabreDAV Backend**: Nextcloud uses SabreDAV as its CalDAV server
- **WebDAV Extensions**: Supports standard WebDAV sync operations
- **Calendar Discovery**: Can auto-discover user calendars via PROPFIND
- **ETag Support**: Proper ETag handling for synchronization
- **Multi-Get Operations**: Supports calendar-multiget for efficiency
## Implementation Plan
### Phase 1: Core CalDAV Write Operations
#### 1.1 Extend CalDAV Client for Write Operations
**File**: `src/caldav_client.rs`
**Required Methods**:
```rust
// Create or update an event
pub async fn put_event(&self, calendar_url: &str, event_path: &str, ical_data: &str) -> CalDavResult<()>
// Create a new calendar
pub async fn create_calendar(&self, calendar_name: &str, display_name: Option<&str>) -> CalDavResult<String>
// Upload multiple events efficiently
pub async fn import_events_batch(&self, calendar_url: &str, events: &[Event]) -> CalDavResult<Vec<CalDavResult<()>>>
```
**Implementation Details**:
- Use HTTP PUT method for individual events
- Handle ETag conflicts with If-Match headers
- Use proper content-type: `text/calendar; charset=utf-8`
- Support both creating new events and updating existing ones
#### 1.2 Enhanced Event to iCalendar Conversion
**File**: `src/event.rs`
**Current Issues**:
- Timezone handling is incomplete
- Missing proper DTSTAMP and LAST-MODIFIED
- Limited property support
**Required Enhancements**:
```rust
impl Event {
pub fn to_ical_for_nextcloud(&self) -> CalDavResult<String> {
// Enhanced iCalendar generation with:
// - Proper timezone handling
// - Nextcloud-specific properties
// - Better datetime formatting
// - Required properties for Nextcloud compatibility
}
pub fn generate_unique_path(&self) -> String {
// Generate filename/path for CalDAV storage
format!("{}.ics", self.uid)
}
}
```
### Phase 2: Nextcloud Integration
#### 2.1 Nextcloud Client Extension
**New File**: `src/nextcloud_client.rs`
```rust
pub struct NextcloudClient {
client: CalDavClient,
base_url: String,
username: String,
}
impl NextcloudClient {
pub fn new(config: NextcloudConfig) -> CalDavResult<Self>
// Auto-discover calendars
pub async fn discover_calendars(&self) -> CalDavResult<Vec<CalendarInfo>>
// Create calendar if it doesn't exist
pub async fn ensure_calendar_exists(&self, name: &str, display_name: Option<&str>) -> CalDavResult<String>
// Import events with conflict resolution
pub async fn import_events(&self, calendar_name: &str, events: Vec<Event>) -> CalDavResult<ImportResult>
// Check if event already exists
pub async fn event_exists(&self, calendar_name: &str, event_uid: &str) -> CalDavResult<bool>
// Get existing event ETag
pub async fn get_event_etag(&self, calendar_name: &str, event_uid: &str) -> CalDavResult<Option<String>>
}
```
#### 2.2 Nextcloud Configuration
**File**: `src/config.rs`
Add Nextcloud-specific configuration:
```toml
[nextcloud]
# Nextcloud server URL (e.g., https://cloud.example.com)
server_url = "https://cloud.example.com"
# Username
username = "your_username"
# App password (recommended) or regular password
password = "your_app_password"
# Default calendar for imports
default_calendar = "imported-events"
# Import behavior
import_behavior = "skip_duplicates" # or "overwrite" or "merge"
# Conflict resolution
conflict_resolution = "keep_existing" # or "overwrite_remote" or "merge"
```
### Phase 3: Import Workflow Implementation
#### 3.1 Import Command Line Interface
**File**: `src/main.rs`
Add new CLI options:
```rust
/// Import events into Nextcloud calendar
#[arg(long)]
import_nextcloud: bool,
/// Target calendar name for Nextcloud import
#[arg(long)]
nextcloud_calendar: Option<String>,
/// Import behavior (skip_duplicates, overwrite, merge)
#[arg(long, default_value = "skip_duplicates")]
import_behavior: String,
/// Dry run - show what would be imported without actually doing it
#[arg(long)]
dry_run: bool,
```
#### 3.2 Import Engine
**New File**: `src/nextcloud_import.rs`
```rust
pub struct ImportEngine {
nextcloud_client: NextcloudClient,
config: ImportConfig,
}
pub struct ImportResult {
pub total_events: usize,
pub imported: usize,
pub skipped: usize,
pub errors: Vec<ImportError>,
pub conflicts: Vec<ConflictInfo>,
}
impl ImportEngine {
pub async fn import_events(&self, events: Vec<Event>) -> CalDavResult<ImportResult> {
// 1. Validate events
// 2. Check for existing events
// 3. Resolve conflicts based on configuration
// 4. Batch upload events
// 5. Report results
}
fn validate_event(&self, event: &Event) -> CalDavResult<()> {
// Ensure required fields are present
// Validate datetime and timezone
// Check for Nextcloud compatibility
}
async fn check_existing_event(&self, event: &Event) -> CalDavResult<Option<String>> {
// Return ETag if event exists, None otherwise
}
async fn resolve_conflict(&self, existing_event: &str, new_event: &Event) -> CalDavResult<ConflictResolution> {
// Based on configuration: skip, overwrite, or merge
}
}
```
### Phase 4: Error Handling and Validation
#### 4.1 Enhanced Error Types
**File**: `src/error.rs`
```rust
#[derive(Debug, thiserror::Error)]
pub enum ImportError {
#[error("Event validation failed: {message}")]
ValidationFailed { message: String },
#[error("Event already exists: {uid}")]
EventExists { uid: String },
#[error("Calendar creation failed: {message}")]
CalendarCreationFailed { message: String },
#[error("Import conflict: {event_uid} - {message}")]
ImportConflict { event_uid: String, message: String },
#[error("Nextcloud API error: {status} - {message}")]
NextcloudError { status: u16, message: String },
}
```
#### 4.2 Event Validation
```rust
impl Event {
pub fn validate_for_nextcloud(&self) -> CalDavResult<()> {
// Check required fields
if self.summary.trim().is_empty() {
return Err(CalDavError::EventProcessing("Event summary cannot be empty".to_string()));
}
// Validate timezone
if let Some(ref tz) = self.timezone {
if !is_valid_timezone(tz) {
return Err(CalDavError::EventProcessing(format!("Invalid timezone: {}", tz)));
}
}
// Check date ranges
if self.start > self.end {
return Err(CalDavError::EventProcessing("Event start must be before end".to_string()));
}
Ok(())
}
}
```
### Phase 5: Testing and Integration
#### 5.1 Unit Tests
**File**: `tests/nextcloud_import_tests.rs`
```rust
#[cfg(test)]
mod tests {
use super::*;
#[tokio::test]
async fn test_event_validation() {
// Test valid and invalid events
}
#[tokio::test]
async fn test_ical_generation() {
// Test iCalendar output format

#### 5.2 Integration Tests
**File**: `tests/nextcloud_integration_tests.rs`
```rust
// These tests require a real Nextcloud instance
// Use environment variables for test credentials
#[tokio::test]
#[ignore] // Run manually with real instance
async fn test_full_import_workflow() {
// Test complete import process
}
#[tokio::test]
#[ignore]
async fn test_duplicate_handling() {
// Test duplicate event handling
}
```
## Implementation Priorities
### Priority 1: Core Import Functionality
1. **Enhanced CalDAV client with PUT support** - Essential for writing events
2. **Basic Nextcloud client** - Discovery and calendar operations
3. **Import command** - CLI interface for importing events
4. **Event validation** - Ensure data quality
### Priority 2: Advanced Features
1. **Conflict resolution** - Handle existing events gracefully
2. **Batch operations** - Improve performance for many events
3. **Error handling** - Comprehensive error management
4. **Testing suite** - Ensure reliability
### Priority 3: Optimization and Polish
1. **Progress reporting** - User feedback during import
2. **Dry run mode** - Preview imports before execution
3. **Configuration validation** - Better error messages
4. **Documentation** - User guides and API docs
## Technical Considerations
### Nextcloud URL Structure
```
Base URL: https://cloud.example.com
Principal: /remote.php/dav/principals/users/{username}/
Calendar Home: /remote.php/dav/calendars/{username}/
Calendar URL: /remote.php/dav/calendars/{username}/{calendar-name}/
Event URL: /remote.php/dav/calendars/{username}/{calendar-name}/{event-uid}.ics
```
### Authentication
- **App Passwords**: Recommended over regular passwords
- **Basic Auth**: Standard HTTP Basic authentication
- **Two-Factor**: Must use app passwords if 2FA enabled
### iCalendar Compliance
- **RFC 5545**: Strict compliance required
- **Required Properties**: UID, DTSTAMP, SUMMARY, DTSTART, DTEND
- **Timezone Support**: Proper TZID usage
- **Line Folding**: Handle long lines properly
### Performance Considerations
- **Batch Operations**: Use calendar-multiget where possible
- **Concurrency**: Import multiple events in parallel
- **Memory Management**: Process large event lists in chunks
- **Network Efficiency**: Minimize HTTP requests
## Success Criteria
### Minimum Viable Product
1. ✅ Can import events with title, datetime, and timezone into Nextcloud
2. ✅ Handles duplicate events gracefully
3. ✅ Provides clear error messages and progress feedback
4. ✅ Works with common Nextcloud configurations
### Complete Implementation
1. ✅ Full conflict resolution strategies
2. ✅ Batch import with performance optimization
3. ✅ Comprehensive error handling and recovery
4. ✅ Test suite with >90% coverage
5. ✅ Documentation and examples
## Next Steps
1. **Week 1**: Implement CalDAV PUT operations and basic Nextcloud client
2. **Week 2**: Add import command and basic workflow
3. **Week 3**: Implement validation and error handling
4. **Week 4**: Add conflict resolution and batch operations
5. **Week 5**: Testing, optimization, and documentation
This plan provides a structured approach to implementing robust Nextcloud CalDAV import functionality while maintaining compatibility with the existing codebase architecture.

# TODO - CalDAV Sync Tool
## 🐛 Known Issues
### Bug #3: Recurring Event End Detection
**Status**: Identified
**Priority**: Medium
**Description**: System not properly handling when recurring events have ended, causing duplicates in target calendar
**Issue**: When recurring events have ended (passed their UNTIL date or COUNT limit), the system may still be creating occurrences or not properly cleaning up old occurrences, leading to duplicate events in the target calendar.
**Files to investigate**:
- `src/event.rs` - `expand_occurrences()` method
- `src/nextcloud_import.rs` - import and cleanup logic
- Date range calculations for event fetching
## ✅ Completed
- [x] Fix timezone preservation in expanded recurring events
- [x] Fix timezone-aware iCal generation for import module
- [x] Fix timezone comparison in `needs_update()` method
- [x] Fix RRULE BYDAY filtering for daily frequency events
## 🔧 Future Tasks
- [ ] Investigate other timezone issues if they exist
- [ ] Cleanup debug logging
- [ ] Add comprehensive tests for timezone handling
- [ ] Consider adding timezone conversion utilities
