A C++ Workbench with Accurate Non-Blocking Garbage Collector for Server Side Internet Applications

摘要

At the Institute of Computer Science Warsaw University of Technology a workbench for building server-side, dependable, Internet applications was designed and implemented. This workbench is a collection of C++ classes. The design and implementation of these classes are briefly described. The most important part of the workbench is the web server, implemented as a C++ class that can be used in a standalone application. To implement the web server a precise, concurrent garbage collector was designed. Our garbage collector is based on the concurrent mark-and-sweep algorithm and smart pointer pattern. It makes the risk of memory access faults or memory leaks much lower than in standard C/C++ applications. The advantages of our workbench are shown in some experiments. We have measured the overhead of our garbage collector and the performance of the workbench. A comparison with other systems is also given.
