(1) at the samba software server, analyzing the received read-write request sent by the client to obtain specific information of the read-write request, wherein the specific information of the read-write request comprises a file descriptor of a read-write file;
(2) when the specific information of the read-write request is acquired, a second sub-thread is created;
(3) performing read-write operation on the obtained specific information of the read-write request by using the second sub thread;
the above is a flow of implementing data read/write operations, and is not intended to limit the present invention.
As another embodiment of the present invention, after the step of monitoring the data read-write action when the samba software server receives the read-write request sent by the client; when the execution of the data reading and writing actions is monitored, the method also comprises the following steps before the first sub-thread is created:
(1) at the samba software server, analyzing the received read-write request sent by the client to obtain specific information of the read-write request, wherein the specific information of the read-write request comprises a file descriptor of a read-write file;
(2) performing read-write operation on the obtained specific information of the read-write request by using the first sub thread;
the above is another implementation flow of data read/write operations, and is not intended to limit the present invention.
In the embodiment of the present invention, as shown in fig. 2, when it is monitored that the data read-write action starts to be executed, the step of creating the first sub-thread specifically includes the following steps:
in step S201, creating an EPOLL component in the created first child thread;
in step S202, adding a file descriptor of the read-write file to the created EPOLL component;
in step S203, an EPOLL _ wait function of the EPOLL component is called, and the EPOLL component is controlled to enter a wait feedback state.
In this embodiment, EPOLL is a poll modified by the Linux kernel to handle large-volume file descriptors, and is an enhanced version of the multiplexing IO interface select/poll in Linux, which can significantly improve the system CPU utilization in the case where only a small amount of programs are active in a large number of concurrent connections. Another reason is that when an event is fetched, it does not have to traverse the entire snooped descriptor set, as long as traversing the descriptor sets that were asynchronously awakened by kernel IO events and added to the Ready queue. Besides providing Level trigger (Level trigger) of select/poll IO event, epoll also provides Edge trigger (Edge trigger), which makes it possible for user space program to buffer IO state, reduces epoll _ wait/epoll _ pwait calls, and improves application program efficiency.
