Building DPHP: Distributed Locks
Durable PHP is an evolving framework designed for creating complex, scalable code, currently exploring distributed locking mechanisms. It facilitates locking multiple entities in a single operation, which poses significant deadlock risks. By adhering to rules like deterministic lock ordering and mandating lock release on orchestration termination, most deadlocks are preventable. The developer also discusses past…

Specifically, I knew what issues any project would have to deal with, and I wanted to create a framework where none of those issues…

Building DPHP: What is it?
Durable PHP is a framework inspired by Akka, Durable Functions, and Dapr, designed to simplify building complex software and enhance testability. It introduces three main components: Activities, Orchestrations, and Entities. Activities handle side effects and are stateless; Orchestrations manage event-sourced code execution, providing linearity despite non-linear event sequences; Entities maintain core application state and behavior,…
