Ensuring thread affinity for interprocess communication in a managed code environment

摘要

A remote procedure call channel for interprocess communication in a managed code environment ensures thread-affinity on both sides of an interprocess communication. Using the channel, calls from a first process to a second process are guaranteed to run on a same thread in a target process. Furthermore, calls from the second process back to the first process will also always execute on the same thread. An interprocess communication manager that allows thread affinity and reentrancy is able to correctly keep track of the logical thread of execution so calls are not blocked in unmanaged hosts. Furthermore, both unmanaged and managed hosts are able to make use of transparent remote call functionality provided by an interprocess communication manager for the managed code environment.

1. A computer-implemented method for enabling interprocess communications and thread affinity, the computer-implemented method comprising:
receiving by a first object executing on a first process in a managed code computing environment, via an interprocess communication mechanism executing on a thread of the first process, an interprocess message from a second object executing on a second process external to a process boundary of said first process, wherein the first process is associated with a channel and the second process is associated with the channel, wherein the channel enables thread reentrancy; and executing said interprocess message on said thread of said first process, whereby cross-process thread affinity with respect to the interprocess message is achieved.
