LC-IDE (Loosely Coupled Integrated Development Environment) is a distributed program development environment where programmers can connect many editors, compilers, and/or test-applications on different machines over the Internet to build high-quality software. It has the advantage that a single programmer can execute many tests on different machines all at once. When the file-alteration-monitor agent of LC-IDE detects a change in the source file repository, it emits a signal to the test agents, and the agents execute tests on the host where they are running. In our former work, we proposed and gave an implementation of LC-IDE by P2P network. In this paper, we focus on the signaling mechanism of LC-IDE and design a new one-to-many signaling mechanism over HTTP requests where a client periodically sends an HTTP polling request to a "core agent," who manages signals and delivers them to all the interested client agents. Wait-free implementation of the signaling machinery is given by compare-and-store technique.
