Runtime virtualization method and apparatus, and runtime virtual machine system

A runtime virtual machine system, comprising:

• an asynchronous input and output (AIO) and timer thread to run in a runtime virtualization environment, wherein the runtime virtualization environment is generated by loading a dynamic runtime library, the dynamic runtime library is constructed based on a native runtime library of an application program, and the dynamic runtime library to simulates a thread implemented in the native runtime library in a co-routine manner;
• a co-routine scheduling thread to schedule at least one co-routine, so that the at least one co-routine completes a task request of the application program;
• a main thread created when the application program is started;
• and
• an event-driven (EPOLL) thread to maintain a state of a file handle and wake up a corresponding co-routine of the at least one co-routine when a read or write cache is ready and a read or write task blocked on the file handle exists;
• and
• the AIO and timer thread to acquires an asynchronous input and output task result and wakes up a co-routine of the at least one co-routine in an input and output (IO) wait;
• when the runtime virtual machine system calls timeout return, a timeout task is popped out and woken up;
• when the runtime virtual machine system calls an asynchronous IO task result, the co-routine in the IO wait is woken up.

An electronic device, comprising:

• one or more processors;
• and
• a storage device, on which one or more programs are stored,
• the one or more programs, when executed by the one or more processors, cause the one or more processors to perform:
• constructing a dynamic runtime library based on a native runtime library of an application program, the dynamic runtime library simulating a thread implemented in the native runtime library in a co-routine manner;
• loading the dynamic runtime library when starting the application program, and generating a runtime virtualization environment and a co-routine scheduling thread running in the runtime virtualization environment, the co-routine scheduling thread being used to schedule at least one co-routine, and the runtime virtualization environment being an environment after a runtime environment generated by the native runtime library is replaced;
• receiving a task request of the application program in the runtime virtualization environment;
• and
• scheduling the at least one co-routine using the co-routine scheduling thread based on the task request and the dynamic runtime library, so that the at least one co-routine completes a task corresponding to the task request.
