Phase 2.2 User Management Discovery - Root Cause Analysis

Critical Finding: Synchronous Email Blocking

Location: /projects/Charon/backend/internal/api/handlers/user_handler.go (lines 400-470)
Component: InviteUser HTTP handler
Issue: Request blocks until SMTP email sending completes

Technical Details

Code Path Analysis:

// InviteUser handler - lines 462-469
if h.MailService.IsConfigured() {
    baseURL, ok := utils.GetConfiguredPublicURL(h.DB)
    if ok {
        appName := getAppName(h.DB)
        if err := h.MailService.SendInvite(user.Email, inviteToken, appName, baseURL); err == nil {
            emailSent = true
        }
    }
}
// ❌ BLOCKS HERE until SendInvite() returns
// ❌ No timeout, no goroutine, no async queue

Mail Service Implementation:

• File: /projects/Charon/backend/internal/services/mail_service.go
• Method: SendEmail() at line 255
• Implementation: Blocking SMTP via smtp.SendMail() (line 315)

Impact:

• HTTP request blocks indefinitely
• No timeout protection
• SMTP server slowness (5-30+ seconds) causes HTTP timeout
• Service becomes unavailable during email operations

Root Cause Impact Matrix

Component	Impact	Severity
InviteUser Endpoint	Blocks on SMTP	CRITICAL
User Management Tests	Timeout during invitation	HIGH
E2E Tests	Test failures when SMTP slow	HIGH
User Workflow	Cannot create users when email slow	HIGH

Recommended Solution: Async Email Pattern

Current (Blocking):

tx.Create(&user)      // ✅ <100ms (database write)
SendEmail(...)        // ❌ BLOCKS 5-30+ seconds (no timeout)
return JSON(user)     // Only if email succeeds (~5000ms to 30s+ total)

Proposed (Async):

tx.Create(&user)      // ✅ <100ms (database write)
go SendEmailAsync(...) // 🔄 Background (non-blocking, fire-and-forget)
return JSON(user)     // ✅ Immediate response (~150ms total) 

Implementation Steps:

1. Create SendEmailAsync() method with goroutine
2. Add optional email configuration flag
3. Implement failure logging for failed email sends
4. Add tests for async behavior
5. Update user invitation flow to return immediately

Effort Estimate: 2-3 hours Priority: High (blocks user management operations)
