Task Timeline

1. Initial Diagnosis - Subfolder Path 404 Issue

Time: ~11:25 PM
Request: "i get a 404 when trying to access a subfolder path"
Actions:

• Investigated routing implementation in src/server/mod.rs
• Verified wiki file structure
• Tested server endpoints with curl
• Root Cause: Axum routing pattern /wiki/:path only captured single path segments, not nested paths like examples/getting-started

Solution: Changed routing from /wiki/:path to /wiki/*path and updated handlers to strip leading slash

---

2. Markdown Link Processing Fix

Time: ~11:40 PM
Request: "now when generating the html, make sure to strip the .md from any internal links"

---

3. Search Results URL Encoding Fix

Time: ~11:50 PM
Request: "when clicking the search results, the /'s are replaced by %2F"
Actions:

• Identified issue in static/js/script.js using encodeURIComponent() on entire path

  # Recreate admin user
  sqlite3 obswiki.db < create_admin.sql
  

• Result: Enhanced logging and manual admin user creation for debugging

---

15. Verify Password Hashing Logic

Time: ~1:35 AM
Request: "are you hashing the inputted password during login request"
Actions:

• Reviewed authentication code in src/auth/mod.rs
• Confirmed proper bcrypt verification flow:
  • Plain text password from user input
  • bcrypt hash stored in database
  • bcrypt::verify(password, &password_hash) for comparison
• Authentication Flow is CORRECT:
  • No double-hashing

---

16. Fix SQLite Boolean Query Issue

Time: ~1:40 AM
Request: User reported query returns 1 row but authentication still fails
Actions:

• Identified SQLite boolean type issue in authentication query
• Problem: WHERE is_active = true doesn't work with SQLite (uses integers 0/1)
• Solution: Changed to WHERE is_active = 1 for proper SQLite compatibility
• Updated authentication query in src/auth/mod.rs
• Root Cause: SQLite stores booleans as integers, not boolean literals
• Result: Authentication query now properly matches active users

---

17. Deep Debug of Login Authentication

Time: ~1:45 AM
Request: "this login straight up does not work lol"
Actions:

• Created Python bcrypt test script to verify hash compatibility
• Tested existing hash $2b$12$LQv3c1yqBWVHxkd0LHAkCOYz6TtxMQJqhN8/Xh4XoKjKS6J8G7/gS
• Generated fresh bcrypt hash for 'admin123' password
• Discovery: Need to verify if stored hash actually matches expected password
• Next Steps: Replace database hash with freshly generated one
• Files Created:
  • test_hash.py - bcrypt verification testing
  • fix_admin.sql - admin user recreation script
• Result: Systematic hash verification and fresh credential generation

---

18. Generate Fresh Admin Hash

• ⚠️ SECURITY WARNING: This is temporary for debugging only
• Credentials:
  • Username: admin
  • Password: admin123 (plaintext stored)
• Result: Simplified authentication to eliminate bcrypt-related issues

---

20. Fix UUID Column Decode Error

Time: ~2:00 AM
Request: User getting panic: "ColumnDecode { index: "id", source: Error(ByteLength { len: 36 })"
Actions:

• Root Cause: SQLite stores UUID as TEXT, but code expects binary UUID format
• Problem: row.get::<Uuid, _>("id") fails on 36-character string UUID
• Solution: Parse UUID string manually with Uuid::parse_str(&row.get::<String, _>("id"))
• Added fallback to generate new UUID if parsing fails
• Result: Fixed UUID column decoding issue that was causing login panic

---

21. Improve Backlinks Layout

Time: ~2:05 AM
Request: "when authenticated, the backlinks box is too large. let's put it at the bottom of the article"
Actions:

• Added border-top separator between content and backlinks
• CSS Changes:
  • Removed aside styling and grid layout
  • Added .backlinks section with horizontal flex layout
  • Backlinks now display as styled buttons with hover effects
• Result: Cleaner single-column layout with backlinks neatly at bottom

---

• Updated h1 title padding to match content width (4rem horizontal)
• Updated backlinks padding to align with content width
• Added responsive padding adjustments for mobile devices
• Result: Articles now use much more screen width for better readability

---

19. Temporary Plaintext Authentication Fix

Time: ~1:55 AM
Request: "just use plaintext for now ... no hasing"
Actions:

• Modified src/auth/mod.rs to use plaintext comparison instead of bcrypt
• Changed verify(password, &password_hash)? to password == password_hash
• Updated admin user password_hash to plaintext 'admin123' in database
• ⚠️ SECURITY WARNING: This is temporary for debugging only
• Credentials:
  • Username: admin
  • Password: admin123 (plaintext stored)
• Result: Simplified authentication to eliminate bcrypt-related issues

• Removed Tailwind CSS CDN and configuration from all HTML templates
• Removed all CSS classes from HTML templates (main wiki, welcome, login, not found pages)
• Removed inline <style> blocks from src/wiki/mod.rs (contained max-width: 800px constraint)
• Removed CSS class assignments from JavaScript file (search-results, tree-node, etc.)
• Removed all dynamic style injection from JavaScript
• Result: Completely unstyled HTML using default browser rendering and full screen width

---

24. Fix JWT Authentication After Style Removal

Time: ~2:25 AM
Request: "ok, now the login doesnt work. can you use some type of session token?"
Initial Approach: Started implementing session cookies but user changed mind Final Request: "actually i changed my mind. i did some research and JWT might be better for this" Actions:

• Reverted back to JWT token approach instead of session cookies
• Fixed login form JavaScript to properly store JWT tokens in localStorage
• Updated token storage to use consistent key: obswiki_token instead of token
• Implemented hybrid authentication checking:
  • Server checks both Authorization: Bearer <token> headers AND auth_token cookies
  • Login form stores token in both localStorage and document.cookie
• Authentication Flow:
  1. Login form sends credentials → server returns JWT
  2. Client stores in localStorage.obswiki_token + document.cookie.auth_token
  3. Browser navigation uses cookie automatically
  4. JavaScript API calls use Authorization header via authenticatedFetch()
• Result: Working JWT authentication with unstyled HTML forms, supporting both browser navigation and API calls

---

25. Implement Wiki Page Editing Functionality

Time: August 15, 2025
Request: "Let's add an editing functionality. Make a new branch for this or a small batch of kittens will die!"

  • Automatically stages and commits edited files if git repository exists
  • Includes commit message with editor username: "Update {path}\n\nEdited by: {username}"
  • Fails silently if no git repository present (as requested)
• 6. Helper Functions:
  • Added get_user_from_headers() to extract user from JWT tokens
  • Made WikiService.can_edit_page() method public for permission checking
• Technical Implementation:
  • Uses existing authentication system (JWT tokens)
  • Respects user role permissions (Admin/Editor can edit, Viewer cannot)
