One of the methods for Ace thread synchronization is to use conditional variables. I didn't really understand them, mainly because Windows There is no corresponding kernel object in the operating system, and the condition variable must be used together with mutex, This is confusing. After repeated tests, we checked the source code of ACE, I finally understand why conditional variables are always used tog

The ACE Framework is designed to be three components, like other IO components or IPC components, based on shared-memory interprocess communication capabilities. The flow action component Ace_mem_stream, the connector component Ace_mem_connector, and the Receive connection component Ace_mem_accpter. The ACE Framework provides two data transfer (distribution deliver) policies for inter-process communication

Browsing the web, suddenly prompting the page to crash (as shown in figure), what's going on? Do you want to turn off all the browsers? It's not that bad, it's because the 2345 ace browsers that use the new architecture have multiple processes, So of course sometimes it happens that the page you're browsing has an exception that is causing the page to crash. Figure I Do not worry about this situation, 2345

Ace tips: create a custom service processor in the ace_acceptor framework Stone Jiang The ace_acceptor framework makes listening for new connections easy, and also makes it easy to create and activate the derived class of ace_svc_handler for new connections. We have learned about the role of the ace_svc_handle: open () Hook Function and the service processor during initialization. In this article, we take a few steps back to understand how the service

pre-allocated connection pool, it should also implement its own resource processing in handle_close; A crash bug occurs during windows debugging: The program crashes when remove_handler is used to analyze the reactor; View the stack and find the reactor. run_reactor_event_loop will call the EchoEventHandler that has already been parsed. This is strange. It is clear that handler has been removed and parsed, why does the reactor still have this pointer (of course it is invalid ). Later I read t
