-# Admin Authentication Implementation
-
-## Overview
-This document describes the implementation of cookie-based authentication for the admin panel.
-
-## Features Implemented
-
-### 1. Cookie Support in HTTP Layer
-- Added `cookies` field to `http_request_t` structure
-- Added `set_cookie` field to `http_response_t` structure
-- Cookie parsing in HTTP request handler
-- Set-Cookie header support in HTTP response
-
-### 2. Database Schema
-Added two new tables:
-- `admin_users`: Stores admin user credentials (username, password)
-- `admin_sessions`: Stores active sessions with expiration
-
-Default admin user created on first run:
-- Username: `admin`
-- Password: `admin`
-
-### 3. Authentication Functions
-- `is_authenticated()`: Checks if request has valid session cookie
-- `get_cookie_value()`: Extracts cookie value by name
-- `generate_session_token()`: Creates random 64-character token
-- `create_session()`: Creates new session in database
-- `destroy_session()`: Removes session from database
-
-### 4. Login Handler (`/admin/login`)
-**GET**: Displays login form with styled HTML
-- Redirects to dashboard if already authenticated
-- Shows username and password input fields
-- Includes CSS styling for better UX
-
-**POST**: Processes login credentials
-- Validates username and password against database
-- Creates session on successful authentication
-- Sets `admin_session` cookie with 7-day expiration
-- Redirects to admin dashboard
-- Shows error message on invalid credentials
-
-### 5. Logout Handler (`/admin/logout`)
-**GET**: Logs out the user
-- Destroys session in database
-- Clears cookie by setting Max-Age=0
-- Shows confirmation page with links
-
-### 6. Dashboard Protection
-Admin dashboard now checks authentication:
-- Returns 403 Forbidden if not authenticated
-- Shows login link for unauthenticated users
-- Displays dashboard with logout link for authenticated users
-
-## Security Features
-- Session tokens are 64 characters long and randomly generated
-- Sessions expire after 7 days
-- Cookies are HttpOnly to prevent XSS attacks
-- Sessions stored in database for server-side validation
-
-## Cookie Details
-- **Name**: `admin_session`
-- **Path**: `/`
-- **Max-Age**: 604800 seconds (7 days)
-- **Flags**: HttpOnly
-
-## Testing
-1. Access `/admin` - should show access denied
-2. Access `/admin/login` - should show login form
-3. Login with `admin` / `admin` - should redirect to dashboard
-4. Access `/admin` - should show dashboard with stats
-5. Click "Logout" - should clear session and show logout page
-6. Try to access `/admin` again - should show access denied
-
-## Code Changes
-- `src/http.h`: Added cookies and set_cookie fields
-- `src/http.c`: Cookie parsing and Set-Cookie header support
-- `src/db.c`: Added admin_users and admin_sessions tables
-- `src/admin.c`: Complete authentication implementation
-
-## Future Improvements
-- Password hashing (currently plain text)
-- CSRF protection
-- Session cleanup for expired sessions
-- Multiple admin users support
-- Password reset functionality

-# Cosmopolitan Compatibility Documentation
-
-This document details the Cosmopolitan Libc compatibility measures implemented in this project to ensure the application is 100% compatible with Cosmopolitan and can be built as an Actually Portable Executable (APE).
-
-## Overview
-
-This project is built with [Cosmopolitan Libc](https://github.com/jart/cosmopolitan), which enables creating Actually Portable Executables (APEs) - single binaries that run natively on multiple operating systems without modification or recompilation.
-
-## Compatibility Guarantees
-
-### ✅ 100% Cosmopolitan Compatible
-
-All code in this project:
-- Uses only standard C11 features
-- Relies exclusively on POSIX-compatible APIs
-- Avoids platform-specific system calls
-- Uses Cosmopolitan's polyfills for cross-platform compatibility
-- Has been tested with Cosmopolitan's compiler toolchain
-
-## Compatible Operating Systems
-
-When compiled with Cosmopolitan, the resulting APE binary runs on:
-
-- **Linux** (x86_64, aarch64)
-- **Windows** (x64)
-- **macOS** (x86_64, Apple Silicon via Rosetta)
-- **FreeBSD** (x86_64)
-- **OpenBSD** (x86_64)
-- **NetBSD** (x86_64)
-
-## Code Standards
-
-### Headers Used
-
-All headers used are standard C11 or POSIX headers that Cosmopolitan fully supports:
-
-```c
-#include // Standard I/O
-#include // Memory allocation, process control
-#include // String operations
-#include // Fixed-width integer types
-#include // size_t, NULL, etc.
-#include // Signal handling
-#include // POSIX API
-#include // Time functions
-#include // Error numbers
-#include // File control
-#include // File status
-```
-
-### Functions Used
-
-All functions are from the standard C library or POSIX APIs that Cosmopolitan implements:
-
-**Memory Management:**
-- `malloc()`, `free()`, `realloc()`, `calloc()`
-- `memcpy()`, `memset()`, `memmove()`
-
-**String Operations:**
-- `strlen()`, `strcpy()`, `strncpy()`, `strcmp()`, `strncmp()`
-- `strcat()`, `strncat()`, `strstr()`, `strchr()`, `strrchr()`
-- `sprintf()`, `snprintf()`
-
-**File I/O:**
-- `fopen()`, `fclose()`, `fread()`, `fwrite()`, `fgets()`, `fputs()`
-- `open()`, `close()`, `read()`, `write()`
-- `unlink()`, `stat()`
-
-**Process Control:**
-- `exit()`, `signal()`, `raise()`
-- `getenv()`
-
-**Time Functions:**
-- `time()`, `gmtime()`, `localtime()`, `strftime()`
-
-## Avoided Features
-
-To maintain 100% Cosmopolitan compatibility, we explicitly avoid:
-
-❌ **Linux-specific system calls** (epoll, inotify, etc.)
-❌ **Windows-specific APIs** (Win32 API)
-❌ **macOS-specific frameworks** (Cocoa, Foundation)
-❌ **GNU extensions** (unless portably implemented)
-❌ **Assembly language** (platform-specific)
-❌ **Inline assembly** (architecture-specific)
-❌ **Platform-specific `#ifdef` blocks** (for core functionality)
-
-## SQLite Integration
-
-SQLite3 is integrated as a portable database solution:
-
-- SQLite is compiled with Cosmopolitan
-- Uses SQLite's amalgamation (single-file distribution)
-- Configured with portable options:
- - `SQLITE_THREADSAFE=0` (single-threaded mode)
- - `SQLITE_OMIT_LOAD_EXTENSION` (no dynamic loading)
-
-## Testing Strategy
-
-### Test Suites
-
-We have four comprehensive test suites to verify Cosmopolitan compatibility:
-
-#### 1. `test_sqlite3.c` - SQLite Core Tests
-- Tests SQLite3 library integration
-- 7 test cases covering database operations
-- Verifies SQLite works with Cosmopolitan
-
-#### 2. `test_db.c` - Database Wrapper Tests
-- Tests our database abstraction layer
-- 6 test cases for wrapper functions
-- Validates migration system
-
-#### 3. `test_cosmopolitan_compat.c` - Libc Compatibility Tests
-- Tests standard C library functions
-- 14 test cases covering:
- - Memory management
- - String operations
- - File I/O
- - Signal handling
- - Time functions
- - Platform detection
-
-#### 4. `test_modules_compat.c` - Module Integration Tests
-- Tests all application modules
-- 12 test cases covering:
- - HTTP module
- - Router module
- - Database module
- - Render module
- - Full stack integration
-
-#### 5. `test_ape_features.c` - APE Feature Tests
-- Tests Actually Portable Executable features
-- 10 test cases covering:
- - Runtime detection
- - Path handling
- - File operations
- - Cross-platform constants
- - Type portability
-
-### Running Tests
-
-```bash
-# Run all tests with Cosmopolitan
-make test
-
-# Run tests in development mode (GCC)
-BUILD_MODE=gcc make test
-
-# Run individual test
-./obj/test_cosmopolitan_compat
-./obj/test_modules_compat
-./obj/test_ape_features
-```
-
-## Build Configuration
-
-### Cosmopolitan Build
-
-```bash
-make # Build with Cosmopolitan (default)
-```
-
-**Compiler:** `cosmocc` (Cosmopolitan C compiler)
-**Flags:** `-O2 -Wall -Wextra -std=c11`
-**Linker:** Static linking (`-static`)
-**Output:** `app.com` (Actually Portable Executable)
-
-### Development Build
-
-```bash
-make dev # Build with GCC
-BUILD_MODE=gcc make # Alternative syntax
-```
-
-**Compiler:** `gcc`
-**Flags:** `-O2 -Wall -Wextra -std=c11`
-**Linker:** Dynamic linking (`-lpthread -ldl -lm`)
-**Output:** `app` (Linux executable)
-
-## Portability Patterns
-
-### Pattern 1: Use Standard Types
-
-```c
-// ✅ Good - portable
-#include
-uint16_t port = 8080;
-size_t length = strlen(str);
-
-// ❌ Bad - not portable
-unsigned short port = 8080; // Size may vary
-int length = strlen(str); // Wrong type
-```
-
-### Pattern 2: Use Standard File I/O
-
-```c
-// ✅ Good - portable
-FILE *fp = fopen("file.txt", "r");
-if (fp) {
- fclose(fp);
-}
-
-// ❌ Bad - Linux-specific
-int fd = open("file.txt", O_RDONLY | O_CLOEXEC);
-```
-
-### Pattern 3: Signal Handling
-
-```c
-// ✅ Good - portable
-#include
-signal(SIGINT, handler);
-signal(SIGTERM, handler);
-
-// ❌ Bad - platform-specific
-#ifdef __linux__
-signal(SIGRT1, handler); // Linux-specific signal
-#endif
-```
-
-### Pattern 4: Memory Allocation
-
-```c
-// ✅ Good - portable
-void *ptr = malloc(size);
-if (ptr) {
- memset(ptr, 0, size);
- free(ptr);
-}
-
-// ❌ Bad - GNU-specific
-void *ptr = malloc(size);
-memset(ptr, 0, malloc_usable_size(ptr)); // GNU extension
-```
-
-## Module-Specific Compatibility
-
-### HTTP Module (`http.c/h`)
-- Uses standard memory allocation
-- Portable integer types (uint16_t for ports)
-- No platform-specific networking (yet - stub implementation)
-
-### Router Module (`router.c/h`)
-- Pure C implementation
-- No external dependencies
-- Uses standard string comparison
-
-### Database Module (`db.c/h`)
-- SQLite compiled with Cosmopolitan
-- Standard SQLite API
-- No OS-specific features
-
-### Render Module (`render.c/h`)
-- Pure string manipulation
-- Standard memory management
-- No platform dependencies
-
-### Main Application (`main.c`)
-- Portable signal handling (SIGINT, SIGTERM)
-- Standard I/O for logging
-- Clean initialization/shutdown
-
-## Verification Checklist
-

- - Check `src/router.c` to understand routing
- - Look at module files to see the structure
-
-3. **Start Developing**:
- - Replace stub implementations with real functionality
- - Add new routes and handlers
- - Implement database schema and queries
- - Create HTML templates
-
-4. **Test Your Changes**:
- ```bash
- make clean

- ```
-
-## Troubleshooting
-
-### Build Fails
-
-**Error**: `cosmocc: command not found`
-
-**Solution**: Either install Cosmopolitan (see [INSTALL.md](INSTALL.md)) or use development mode:
-```bash
-make dev
-```
-
-### Permission Denied
-
-**Error**: `./app: Permission denied`
-
-**Solution**: Make the binary executable:
-```bash
-chmod +x app
-./app
-```
-
-### Port Already in Use
-
-**Error**: `Failed to initialize HTTP server`
-
-**Solution**: The current stub doesn't actually bind to a port, but when implementing the full server, either change the port in `src/main.c` or kill the conflicting process.

-# Quote Reply Feature Implementation
-
-## Overview
-Implemented a quote reply feature for the message board that allows users to reply to specific posts, with visual indicators and the ability to expand/collapse quoted post content.
-
-## Changes Made
-
-### 1. Database Schema (src/db.c)
-- Added `reply_to` column to the `posts` table
-- Type: INTEGER (nullable)
-- Foreign key reference to `posts(id)`
-- Allows tracking which post is being replied to
-
-### 2. Thread View HTML/CSS/JavaScript (src/board.c)
-
-#### CSS Styling
-- `.post`: Post container with border
-- `.post-header`: Flexbox layout for header (name/id on left, reply button on right)
-- `.reply-btn`: Green button styled for reply action
-- `.quote-ref`: Blue clickable reference to quoted post (e.g., ">>123")
-- `.quoted-post`: Hidden by default, gray background with blue left border
-- `.quoted-post.expanded`: Visible state when toggled
-
-#### JavaScript Functions
-- `replyToPost(postId)`: Sets the reply_to hidden field and scrolls to reply form
-- `toggleQuote(postId)`: Toggles visibility of quoted post content
-
-#### HTML Structure
-Each post now displays:
-- Post header with author name and post ID (#123)
-- If replying to another post: clickable reference (>>123)
-- Reply button on the right side
-- Quoted post content (hidden by default, can be toggled)
-- Post content
-
-### 3. Post Display Logic (src/board.c - thread_view_handler)
-- Updated SQL query to LEFT JOIN with posts table to fetch reply_to data
-- Query now fetches: post data + referenced post data (id, author, content)
-- Displays quote reference link when post has reply_to
-- Shows collapsible quoted post content
-
-### 4. Reply Form (src/board.c - thread_view_handler)
-- Added hidden `reply_to` field with id="reply_to"
-- Added id="content" to textarea for JavaScript focus
-- Added id="reply-form" to form for scrolling
-
-### 5. Post Creation Handler (src/board.c - post_create_handler)
-- Parse `reply_to` parameter from POST body
-- Store reply_to value in database (or NULL if not replying)
-- Updated INSERT statement to include reply_to column
-
-### 6. Thread Creation Handler (src/board.c - thread_create_handler)
-- Updated initial post creation to include reply_to field (always NULL for OP)
-
-## User Interaction Flow
-
-1. User views a thread with multiple posts
-2. Each post has a "Reply" button on the right side
-3. User clicks "Reply" on a specific post
-4. Browser scrolls to reply form
-5. Hidden reply_to field is populated with the post ID
-6. User writes their reply and submits
-7. New post is created with reference to original post
-8. Post displays with ">>123" reference link
-9. Clicking ">>123" expands/collapses the quoted post content
-
-## Features
-
-✅ Reply buttons on all posts (right-aligned)
-✅ Quote references displayed as clickable links (>>PostID)
-✅ Expand/collapse functionality for quoted posts
-✅ Smooth scrolling to reply form
-✅ Auto-focus on content textarea
-✅ Visual styling with colors and borders
-✅ Database foreign key relationships
-✅ NULL handling for non-reply posts
-
-## Testing
-
-Run `./test_reply_feature.sh` to verify:
-- Database schema includes reply_to column
-- Posts can be created with reply_to references
-- HTML includes all necessary elements (buttons, scripts, styles)
-- Quote references are displayed correctly
-
-## Browser Compatibility
-
-Uses standard JavaScript and CSS features:
-- classList.toggle() for show/hide
-- scrollIntoView() with smooth behavior
-- Flexbox for layout
-- Works in all modern browsers

-# Security Updates
-
-This document describes the security enhancements implemented in the codebase.
-
-## Changes Summary
-
-### 1. Restricted Board Creation to Admin Only
-
-**Files Modified:** `src/board.c`
-
-- Added authentication check to `board_create_handler()` to ensure only authenticated administrators can create new boards
-- Modified `board_list_handler()` to only display the "Create New Board" form to authenticated administrators
-- Returns HTTP 403 Forbidden when non-admin users attempt to access board creation
-
-**Implementation Details:**
-- Uses `admin_is_authenticated(req)` function to verify admin session
-- Form is conditionally rendered based on authentication status
-- Explicit error message shown when unauthorized users try to create boards
-
-### 2. Admin Password Change Feature
-
-**Files Modified:** `src/admin.c`, `src/admin.h`
-
-Added new functionality allowing administrators to change their password:
-- New route: `/admin/change-password` (GET and POST)
-- New handler: `admin_change_password_handler()`
-- Link added to admin dashboard for easy access
-
-**Features:**
-- Requires current password verification
-- New password confirmation to prevent typos
-- Password validation before update
-- Secure session-based authentication required
-- Clear success/error messages
-
-**Helper Function Added:**
-- `get_current_user_id()` - Retrieves user ID from session token
-
-### 3. XSS Attack Prevention
-
-**Files Modified:** `src/render.c`, `src/render.h`, `src/board.c`
-
-Implemented comprehensive XSS (Cross-Site Scripting) protection:
-
-#### New Escaping Functions:
-1. **`render_escape_html()`** - Escapes HTML special characters
- - Converts: `&`, `<`, `>`, `"`, `'` to HTML entities
- - Used for all user-generated content displayed in HTML context
-
-2. **`render_escape_js()`** - Escapes JavaScript special characters
- - Escapes: `\`, `'`, `"`, newlines, carriage returns, tabs
- - Used for content embedded in JavaScript contexts (e.g., onclick attributes)
-
-#### Content Escaping Applied To:
-- Board names, titles, and descriptions
-- Thread subjects
-- Post content
-- Author names
-- Kaomoji category titles
-- Kaomoji items (both in HTML display and JavaScript onclick handlers)
-- Quoted post content
-
-**XSS Protection Strategy:**
-- All user-generated content is escaped before rendering
-- Separate escaping for HTML and JavaScript contexts
-- Memory properly managed (allocated escaped strings are freed)
-- Fallback to original content if escaping fails
-
-### 4. Authentication Function Made Public
-
-**Files Modified:** `src/admin.c`, `src/admin.h`
-
-- Renamed `is_authenticated()` to `admin_is_authenticated()`
-- Made function public (exported in header file)
-- Allows other modules (like board.c) to check admin authentication status
-
-## Security Benefits
-
-1. **Authorization Control**: Prevents unauthorized users from creating boards, ensuring only admins can manage board structure
-
-2. **Password Security**: Allows admins to change compromised passwords, requires verification of current password
-
-3. **XSS Prevention**: Protects against malicious JavaScript injection through user input, preventing:
- - Cookie theft
- - Session hijacking
- - Defacement
- - Phishing attacks
- - Malicious redirects
-
-## Testing Recommendations
-
-1. **Board Creation Authorization:**
- - Verify non-logged-in users cannot see or access board creation form
- - Verify logged-in admin can create boards
- - Test direct POST to `/board/create` without auth returns 403
-
-2. **Password Change:**
- - Test with incorrect current password
- - Test with mismatched new passwords
- - Test successful password change
- - Verify new password works for login
-
-3. **XSS Prevention:**
- - Try injecting `` in various fields
- - Test special characters in board names, titles, descriptions
- - Test HTML tags in post content and author names
- - Verify kaomoji with special characters display correctly
-
-## Migration Notes
-
-- No database schema changes required
-- Existing data remains compatible
-- No breaking changes to existing functionality
-- All changes are additive security enhancements

-# SQLite3 Integration Guide
-
-This document describes the SQLite3 integration in the Cosmopolitan Web Application.
-
-## Overview
-
-SQLite3 has been integrated as an embedded database, compiled statically into the application binary. This provides a zero-configuration, serverless database solution that works across all supported platforms.
-
-## Components
-
-### 1. SQLite3 Source Code
-
-Located in `third_party/sqlite3/`:
-- **sqlite3.c** - Complete SQLite3 implementation (amalgamation)
-- **sqlite3.h** - Public API header
-- **sqlite3ext.h** - Extension API header
-- **Version**: 3.46.1 (August 2024)
-
-### 2. Database Wrapper Layer
-
-Located in `src/`:
-- **db.h** - Database API interface
-- **db.c** - Wrapper implementation
-
-The wrapper provides simplified functions:
-- `db_init(path)` - Initialize database connection
-- `db_close()` - Close database connection
-- `db_exec(sql)` - Execute SQL statement
-- `db_prepare(sql)` - Prepare SQL statement
-- `db_step(stmt)` - Execute prepared statement
-- `db_finalize(stmt)` - Finalize prepared statement
-- `db_migrate()` - Run database migrations
-
-### 3. Test Suite
-
-Located in `tests/`:
-- **test_sqlite3.c** - Direct SQLite3 API tests (7 test cases)
-- **test_db.c** - Database wrapper tests (6 test cases)
-
-## Build System Integration
-
-### Makefile
-
-The Makefile has been updated to:
-- Include SQLite3 header path: `-Ithird_party/sqlite3`
-- Compile SQLite3 amalgamation with optimizations
-- Link SQLite3 into the main application
-- Support test compilation and execution
-
-Build flags for SQLite3:
-```makefile
--DSQLITE_THREADSAFE=0 # Single-threaded mode
--DSQLITE_OMIT_LOAD_EXTENSION # Disable dynamic loading
-```
-
-### Build Script
-
-The `build.sh` script has been updated to include SQLite3 compilation.
-
-## Database Schema
-
-The application includes a migration system that creates the following tables:
-
-### boards
-- `id` INTEGER PRIMARY KEY AUTOINCREMENT
-- `name` TEXT NOT NULL UNIQUE
-- `title` TEXT NOT NULL
-- `description` TEXT
-- `created_at` DATETIME DEFAULT CURRENT_TIMESTAMP
-
-### threads
-- `id` INTEGER PRIMARY KEY AUTOINCREMENT
-- `board_id` INTEGER NOT NULL (FK → boards.id)
-- `subject` TEXT NOT NULL
-- `created_at` DATETIME DEFAULT CURRENT_TIMESTAMP
-
-### posts
-- `id` INTEGER PRIMARY KEY AUTOINCREMENT
-- `thread_id` INTEGER NOT NULL (FK → threads.id)
-- `author` TEXT
-- `content` TEXT NOT NULL
-- `created_at` DATETIME DEFAULT CURRENT_TIMESTAMP
-
-## Usage Examples
-
-### Initialize Database
-```c
-#include "db.h"
-
-int main(void) {
- if (db_init("app.db") != 0) {
- fprintf(stderr, "Failed to initialize database\n");
- return 1;
- }
-
- // Run migrations
- if (db_migrate() != 0) {
- fprintf(stderr, "Failed to run migrations\n");
- db_close();
- return 1;
- }
-
- // Your application code here
-
- db_close();
- return 0;
-}
-```
-
-### Execute SQL
-```c
-int rc = db_exec("INSERT INTO boards (name, title) VALUES ('tech', 'Technology');");
-if (rc != 0) {
- fprintf(stderr, "Insert failed\n");
-}
-```
-
-### Query Data
-```c
-sqlite3_stmt *stmt = db_prepare("SELECT id, name FROM boards;");
-if (stmt != NULL) {
- while (db_step(stmt) == SQLITE_ROW) {
- int id = sqlite3_column_int(stmt, 0);
- const char *name = (const char *)sqlite3_column_text(stmt, 1);
- printf("Board %d: %s\n", id, name);
- }
- db_finalize(stmt);
-}
-```
-
-### Prepared Statements with Parameters
-```c
-sqlite3_stmt *stmt = db_prepare(
- "INSERT INTO posts (thread_id, author, content) VALUES (?, ?, ?);"
-);
-if (stmt != NULL) {
- sqlite3_bind_int(stmt, 1, thread_id);
- sqlite3_bind_text(stmt, 2, author, -1, SQLITE_STATIC);
- sqlite3_bind_text(stmt, 3, content, -1, SQLITE_STATIC);
-
- if (db_step(stmt) == SQLITE_DONE) {
- printf("Post created successfully\n");
- }
- db_finalize(stmt);
-}
-```
-
-## Testing

-- Linux (x86_64, ARM64)
-- Windows (x86_64)
-- macOS (x86_64, ARM64)
-- FreeBSD, OpenBSD, NetBSD
-
-## Performance Considerations
-
-1. **Single-threaded mode** (`SQLITE_THREADSAFE=0`) provides better performance
-2. **Static linking** eliminates runtime dependencies
-3. **Embedded database** means no network latency
-4. **In-process** execution for maximum efficiency
-
-## Security
-
-1. **Extension loading disabled** - Prevents dynamic code loading
-2. **Prepared statements** - Protects against SQL injection
-3. **No external dependencies** - Reduces attack surface
-4. **Static compilation** - Tamper-resistant binary
-
-## Debugging
-
-### Enable SQLite3 Debug Output
-Modify compile flags in Makefile:
-```makefile
--DSQLITE_DEBUG
-```
-
-### View SQL Execution
-The wrapper functions print SQL statements and errors to stderr.
-
-### Inspect Database
-```bash
-# Using SQLite3 CLI (if installed)
-sqlite3 app.db
-
-# List tables
-.tables
-
-# View schema
-.schema
-
-# Query data
-SELECT * FROM boards;
-```
-
-## Troubleshooting
-
-### Build Errors
-
-**Problem**: `sqlite3.h: No such file or directory`
-**Solution**: Ensure `third_party/sqlite3/` directory exists with SQLite3 files
-
-**Problem**: Linker errors with SQLite3 symbols
-**Solution**: Verify `$(SQLITE3_OBJ)` is included in link command
-
-### Runtime Errors
-
-**Problem**: `Database not initialized`
-**Solution**: Call `db_init()` before using database functions
-
-**Problem**: SQL syntax errors
-**Solution**: Check SQL syntax, use prepared statements for dynamic queries
-
-## Future Enhancements
-
-Potential improvements:
-- Connection pooling (if multi-threading is enabled)
-- Query result caching
-- Database backup/restore functionality
-- Migration version tracking
-- Performance monitoring
-- Full-text search integration

-
-## Overview
-
-The application started with stub implementations that returned simple HTML messages. This guide shows the step-by-step process of implementing real functionality.
-
-### Technologies Used
-- **C11** - Programming language
-- **SQLite3** - Embedded database
-- **Prepared Statements** - SQL injection prevention
-- **HTML Forms** - User interaction
-
-## Step 1: Board Module
-
-### 1.1 Database Query Functions
-
-First, we implemented the database query functions to retrieve data:
-
-**`board_get_by_id()`**
-```c
-board_t *board_get_by_id(int64_t id) {
- sqlite3_stmt *stmt = db_prepare("SELECT id, name, description FROM boards WHERE id = ?");
- if (!stmt) return NULL;
-
- sqlite3_bind_int64(stmt, 1, id);
-
- board_t *board = NULL;
- if (db_step(stmt) == SQLITE_ROW) {
- board = malloc(sizeof(board_t));
- if (board) {
- board->id = sqlite3_column_int64(stmt, 0);
- board->name = strdup((const char *)sqlite3_column_text(stmt, 1));
- board->description = strdup((const char *)sqlite3_column_text(stmt, 2));
- }
- }
-
- db_finalize(stmt);
- return board;
-}
-```
-
-**Key Points:**
-- Uses prepared statements for security
-- Checks for NULL return values
-- Properly allocates memory for strings with `strdup()`
-- Cleans up statement with `db_finalize()`
-
-### 1.2 List Handler
-
-**`board_list_handler()`** - Shows all boards
-
-```c
-http_response_t *board_list_handler(http_request_t *req) {
- char *html = malloc(8192);
- // Build HTML with board list
- sqlite3_stmt *stmt = db_prepare("SELECT id, name, title, description FROM boards");
- while (db_step(stmt) == SQLITE_ROW) {
- // Append each board to HTML
- }
- db_finalize(stmt);
- return http_response_create(200, "text/html", html, len);
-}
-```
-
-**Implementation Steps:**
-1. Allocate buffer for HTML response
-2. Write HTML header and opening tags
-3. Query database for all boards
-4. Loop through results and append to HTML
-5. Add form for creating new boards
-6. Return HTTP response
-
-### 1.3 Board View Handler
-
-**`board_view_handler()`** - Shows threads in a board
-
-```c
-http_response_t *board_view_handler(http_request_t *req) {
- // Parse board ID from query string
- int64_t board_id = 1;
- if (req->query_string) {
- sscanf(req->query_string, "id=%lld", &board_id);
- }
-
- // Get board info
- board_t *board = board_get_by_id(board_id);
- if (!board) {
- return http_response_create(404, "text/html", error_html, strlen(error_html));
- }
-
- // Query threads with post count
- sqlite3_stmt *stmt = db_prepare(
- "SELECT t.id, t.subject, COUNT(p.id) "
- "FROM threads t LEFT JOIN posts p ON t.id = p.thread_id "
- "WHERE t.board_id = ? GROUP BY t.id"
- );
- // ... build HTML
-}
-```
-
-**Implementation Steps:**
-1. Parse `board_id` from query string
-2. Fetch board details
-3. Return 404 if board not found
-4. Query threads with LEFT JOIN to count posts
-5. Display threads with post counts
-6. Include form to create new thread
-
-### 1.4 Thread View Handler
-
-**`thread_view_handler()`** - Shows posts in a thread
-
-```c
-http_response_t *thread_view_handler(http_request_t *req) {
- // Parse thread ID
- int64_t thread_id = 1;
- sscanf(req->query_string, "id=%lld", &thread_id);
-
- // Get thread with first post
- thread_t *thread = thread_get_by_id(thread_id);
-
- // Query all replies
- sqlite3_stmt *stmt = db_prepare(
- "SELECT id, author, content FROM posts WHERE thread_id = ?"
- );
- // ... build HTML
-}
-```
-
-### 1.5 Create Handlers
-
-**`thread_create_handler()`** - Creates new thread
-
-```c
-http_response_t *thread_create_handler(http_request_t *req) {
- // Parse form data from POST body
- char *body_copy = strdup(req->body);
- char *token = strtok(body_copy, "&");
- while (token) {
- char *eq = strchr(token, '=');
- // Parse key=value pairs
- }
-
- // Insert thread
- sqlite3_stmt *stmt = db_prepare("INSERT INTO threads (board_id, subject) VALUES (?, ?)");
- sqlite3_bind_int64(stmt, 1, board_id);
- sqlite3_bind_text(stmt, 2, subject, -1, SQLITE_TRANSIENT);
- db_step(stmt);
- int64_t thread_id = sqlite3_last_insert_rowid(db_get_connection());
-
- // Insert first post
- // ... return success message
-}
-```
-
-**Form Parsing Strategy:**
-1. Duplicate request body (strtok modifies string)
-2. Split on '&' to get key=value pairs
-3. Split each pair on '=' to get key and value
-4. Store values in local variables
-5. Free duplicated string
-
-**Database Insertion:**
-1. Prepare INSERT statement
-2. Bind parameters
-3. Execute with `db_step()`
-4. Get inserted ID with `sqlite3_last_insert_rowid()`
-5. Finalize statement
-
-### 1.6 Sample Data Initialization
-
-**`board_init()`** - Create sample boards on first run
-
-```c
-void board_init(void) {
- sqlite3_stmt *stmt = db_prepare("SELECT COUNT(*) FROM boards");
- if (stmt && db_step(stmt) == SQLITE_ROW) {
- int count = sqlite3_column_int(stmt, 0);
- if (count == 0) {
- db_exec("INSERT INTO boards (name, title, description) VALUES "
- "('general', 'General Discussion', 'General topics'), "
- "('tech', 'Technology', 'Tech discussions'), "
- "('random', 'Random', 'Off-topic')");
- }
- }
-}
-```
-
-## Step 2: Admin Module
-
-### 2.1 Dashboard with Statistics
-
-**`admin_dashboard_handler()`** - Shows statistics
-
-```c
-http_response_t *admin_dashboard_handler(http_request_t *req) {
- // Count boards
- sqlite3_stmt *stmt = db_prepare("SELECT COUNT(*) FROM boards");
- db_step(stmt);
- int board_count = sqlite3_column_int(stmt, 0);
- db_finalize(stmt);
-
- // Count threads
- // Count posts
- // Query recent threads
-
- // Build HTML with statistics
-}
-```
-
-**Implementation Steps:**
-1. Query count for each table (boards, threads, posts)
-2. Query recent activity (latest 10 threads)
-3. Display statistics in organized format
-4. Link to threads for quick access
-
-## Step 3: Upload Module
-
-### 3.1 Upload Handler
-
-**`upload_handler()`** - Handle file uploads
-
-```c
-http_response_t *upload_handler(http_request_t *req) {
- if (strcmp(req->method, "GET") == 0) {
- // Show upload form
- return http_response_create(200, "text/html", form_html, strlen(form_html));
- }
-
- // Parse uploaded file
- upload_file_t *file = upload_parse_multipart(req);
-
- // Save to disk
- char save_path[512];
- snprintf(save_path, sizeof(save_path), "%s/%s", upload_directory, file->filename);
- int result = upload_save_file(file, save_path);
-
- // Return success/error
-}
-```
-
-### 3.2 File Parsing
-
-**`upload_parse_multipart()`** - Parse file from request
-
-```c
-upload_file_t *upload_parse_multipart(http_request_t *req) {
- upload_file_t *file = malloc(sizeof(upload_file_t));
- file->filename = strdup("uploaded_file.dat");
- file->content_type = strdup("application/octet-stream");
- file->size = req->body_len;
- file->data = malloc(file->size);
- memcpy(file->data, req->body, file->size);
- return file;
-}
-```
-
-### 3.3 File Saving
-
-**`upload_save_file()`** - Write file to disk
-
-```c
-int upload_save_file(upload_file_t *file, const char *save_path) {
- FILE *fp = fopen(save_path, "wb");
- if (!fp) return -1;
-
- size_t written = fwrite(file->data, 1, file->size, fp);
- fclose(fp);
-
- return (written == file->size) ? 0 : -1;
-}
-```
-
-## Testing

-## Usage Examples
-
-### Creating a Thread Programmatically
-
-```bash
-# Insert thread
-sqlite3 app.db "INSERT INTO threads (board_id, subject) VALUES (1, 'Hello World');"
-
-# Insert first post
-sqlite3 app.db "INSERT INTO posts (thread_id, author, content) VALUES (1, 'User', 'First post');"
-
-# Verify
-sqlite3 app.db "SELECT t.subject, p.author, p.content FROM threads t JOIN posts p ON t.id = p.thread_id;"
-```
-
-### Query Examples
-
-```bash
-# List all boards
-sqlite3 app.db "SELECT name, title FROM boards;"
-
-# Count threads per board
-sqlite3 app.db "SELECT b.name, COUNT(t.id) FROM boards b LEFT JOIN threads t ON b.id = t.board_id GROUP BY b.id;"
-
-# Get thread with posts
-sqlite3 app.db "SELECT t.subject, p.author, p.content FROM threads t JOIN posts p ON t.id = p.thread_id WHERE t.id = 1;"
-```
-
-## Code Patterns Used
-
-### 1. Memory Management
-```c
-char *buffer = malloc(size);
-if (!buffer) {
- // Handle error
-}
-// Use buffer
-free(buffer);
-```
-
-### 2. Prepared Statements
-```c
-sqlite3_stmt *stmt = db_prepare("SELECT * FROM table WHERE id = ?");
-sqlite3_bind_int64(stmt, 1, id);
-while (db_step(stmt) == SQLITE_ROW) {
- // Process row
-}
-db_finalize(stmt);
-```
-
-### 3. String Building
-```c
-int len = snprintf(html, size, "...");
-len += snprintf(html + len, size - len, "more...");
-```
-
-### 4. Error Handling
-```c
-if (!resource) {
- const char *err = "Error";
- return http_response_create(500, "text/html", err, strlen(err));
-}
-```
-
-## Summary
-
-The implementation followed these principles:
-
-1. **Security First**: Always use prepared statements
-2. **Memory Safety**: Check all allocations, free all resources
-3. **Error Handling**: Return appropriate HTTP status codes
-4. **User Feedback**: Provide clear success/error messages
-5. **Data Validation**: Check inputs before database operations
-
-All core functionality is now working:
-- ✅ Board listing and viewing
-- ✅ Thread creation and viewing
-- ✅ Post replies
-- ✅ Admin statistics
-- ✅ File uploads
-- ✅ Sample data initialization

-## 🔧 Technical Details
-
-### SQLite Configuration
-- **WAL Mode**: Better concurrency, allows readers during writes
-- **Synchronous NORMAL**: Balance between safety and performance
-- **mmap_size=0**: Prevents segfaults if database file is deleted/moved
-- **busy_timeout=5000**: 5-second wait for locked database
-
-### Security Considerations
-- Directory permissions: 0755 (rwxr-xr-x)
-- Database file auto-created with SQLite defaults
-- Upload directory isolated from application code
-
-## 📊 Impact
-
-### Reliability
-- ✅ No more ENOENT-related crashes
-- ✅ Graceful handling of missing directories
-- ✅ Better error messages for debugging
-
-### Performance
-- ✅ WAL mode improves read/write concurrency
-- ✅ NORMAL synchronous reduces I/O overhead
-- ⚠️ Disabling mmap may slightly reduce read performance (acceptable trade-off for stability)
-
-### DevOps
-- ✅ Automated release process
-- ✅ No manual binary building required
-- ✅ Consistent versioning with Git tags
-
