woikos	9da1784b1b	Add Blossom bandwidth limiting and tune rate limiters (v0.49.0) - Add token-bucket bandwidth rate limiting for Blossom uploads - ORLY_BLOSSOM_RATE_LIMIT enables limiting (default: false) - ORLY_BLOSSOM_DAILY_LIMIT_MB sets daily limit (default: 10MB) - ORLY_BLOSSOM_BURST_LIMIT_MB sets burst cap (default: 50MB) - Followed users, admins, owners are exempt (unlimited) - Change emergency mode throttling from exponential to linear scaling - Old: 16x multiplier at emergency threshold entry - New: 1x at threshold, +1x per 20% excess pressure - Reduce follows ACL throttle increment from 200ms to 25ms per event - Update dependencies Files modified: - app/blossom.go: Pass rate limit config to blossom server - app/config/config.go: Add Blossom rate limit config options - pkg/blossom/ratelimit.go: New bandwidth limiter implementation - pkg/blossom/server.go: Add rate limiter integration - pkg/blossom/handlers.go: Check rate limits on upload/mirror/media - pkg/ratelimit/limiter.go: Linear emergency throttling - pkg/acl/follows.go: Reduce default throttle increment Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>	4 months ago
mleku	f16ab3077f	Interim release: documentation updates and rate limiting improvements - Add applesauce library reference documentation - Add rate limiting test report for Badger - Add memory monitoring for rate limiter (platform-specific implementations) - Enhance PID-controlled adaptive rate limiting - Update Neo4j and Badger monitors with improved load metrics - Add docker-compose configuration - Update README and configuration options 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>	5 months ago
mleku	28b41847a6	Generalize PID controller as reusable library with abstract interfaces - Create pkg/interfaces/pid for generic PID controller interfaces: - ProcessVariable: abstract input (value + timestamp) - Source: provides process variable samples - Output: controller output with P/I/D components and clamping info - Controller: generic PID interface with setpoint/gains - Tuning: configuration struct for all PID parameters - Create pkg/pid as standalone PID controller implementation: - Thread-safe with mutex protection - Low-pass filtered derivative to suppress high-frequency noise - Anti-windup on integral term - Configurable output clamping - Presets for common use cases: rate limiting, PoW difficulty, temperature control, motor speed - Update pkg/ratelimit to use generic pkg/pid.Controller: - Limiter now uses pidif.Controller interface - Type assertions for monitoring/debugging state access - Maintains backward compatibility with existing API The generic PID package can now be used for any dynamic adjustment scenario beyond rate limiting, such as blockchain PoW difficulty adjustment, temperature regulation, or motor speed control. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>	5 months ago
mleku	88b0509ad8	Implement PID-controlled adaptive rate limiting for database operations - Add LoadMonitor interface in pkg/interfaces/loadmonitor/ for database load metrics - Implement PIDController with filtered derivative to suppress high-frequency noise - Proportional (P): immediate response to current error - Integral (I): eliminates steady-state offset with anti-windup clamping - Derivative (D): rate-of-change prediction with low-pass filtering - Create BadgerLoadMonitor tracking L0 tables, compaction score, and cache hit ratio - Create Neo4jLoadMonitor tracking query semaphore usage and latencies - Add AdaptiveRateLimiter combining PID controllers for reads and writes - Configure via environment variables: - ORLY_RATE_LIMIT_ENABLED: enable/disable rate limiting - ORLY_RATE_LIMIT_TARGET_MB: target memory limit (default 1500MB) - ORLY_RATE_LIMIT__K[PID]: PID gains for reads/writes - ORLY_RATE_LIMIT_MAX__MS: maximum delays - ORLY_RATE_LIMIT_*_TARGET: setpoints for reads/writes - Integrate rate limiter into Server struct and lifecycle management - Add comprehensive unit tests for PID controller behavior Files modified: - app/config/config.go: Add rate limiting configuration options - app/main.go: Initialize and start/stop rate limiter - app/server.go: Add rateLimiter field to Server struct - main.go: Create rate limiter with appropriate monitor - pkg/run/run.go: Pass disabled limiter for test instances - pkg/interfaces/loadmonitor/: New LoadMonitor interface - pkg/ratelimit/: New PID controller and limiter implementation 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>	5 months ago
