In some embodiments of the invention, computing device 100 includes one or more processors, and one or more readable storage media storing program instructions. The program instructions, when configured to be executed by one or more processors, cause a computing device to perform a method of processing a message in an embodiment of the invention.
The message processing method of the present invention can be executed in the production side and the consumption side, and the message processing method executed in the production side will be described first.
Fig. 2 shows a flow diagram of a method 200 of processing a message according to one embodiment of the invention. Method 200 may be performed in an operating system of a computing device, such as computing device 100 described above. The operating system may be any operating system, such as: windows, linux, unix, but is not so limited. The computing device executing the method 200 includes a producer side and a consumer side, wherein the producer side may also refer to a producer process, and the consumer side may also refer to a consumer process. Method 200 is suitable for execution in a production side of a computing device, such as computing device 100 described above. As shown in fig. 2, the method 200 begins at step 210.
In step 210, a memory area shared by the producer and the consumer and a semaphore for inter-process communication between the consumer and the producer are initialized.
According to the embodiment of the invention, after the consumption end creates the memory area shared by the consumption end and the production end, the production end and the consumption end initialize the shared memory area. By reading or writing data into the shared memory area, interprocess communication can be realized between the two processes of the consumption end and the production end. By utilizing the memory area, the data (such as messages) is not required to be copied, and only two processes of the consumption end and the production end are required to be mapped into the same physical memory (namely a shared memory area) in the computing equipment, so that the consumption end and the production end can both see the memory area, and when one process of the two processes reads the memory area, the other process can write the memory area.
According to an embodiment of the invention, a semaphore for interprocess communication between a consumer and a producer is initialized. Here, the semaphore for inter-process communication may be used to indicate the number of resources allowed to be accessed, and may be set to 0 when the semaphore for inter-process communication is initialized, indicating that no resources are accessible.
Subsequently, in step 220, the memory cells of the memory region are obtained.
In some embodiments, a start position of the write information of the memory unit in the memory area shared by the producer and the consumer is obtained, so that the message is subsequently written into the memory area from the start position. Optionally, in the memory area, the production end maps the memory area of the target file, so that the production end can directly access the target file corresponding to the address of the memory area of the target file to obtain the message recorded in the target file. Optionally, the production end and the consumption end both perform mapping of the storage area of the target file, so that the production end and the consumption end can directly access the target file, the production end reads the message from the address of the storage area of the target file and writes the message into the memory unit, and then the consumption end acquires the written message from the memory unit and performs corresponding processing on the message.
Subsequently, in step 230, the message is written to the memory unit by multithreading and the semaphore for interprocess communication is updated so that the consuming side processes the message.
In some embodiments, the multithreading writes the message to the memory unit by repeating the obtaining of the current write address of the memory unit from the start position of the write information of the memory unit through an atomic operation. Taking the example of writing multiple messages, when writing the first message, it is written into the initial position, and then the subsequent messages are written into the latest write address currently acquired (when writing the message). Specifically, after reading the message from the target file corresponding to the address of the storage area of the target file, the production end writes the message into the memory unit.
In some embodiments, the semaphore for inter-process communication may be set to 0 during initialization, and then when a message is written to the memory unit, the semaphore for inter-process communication may be updated by increasing the semaphore for inter-process communication by a corresponding amount, for example, by one. When the semaphore of the interprocess communication is a positive value, the resource which is allowed to be accessed exists in the memory area, and the consumption end can determine that the resource which is allowed to be accessed exists in the memory area through the semaphore of the interprocess communication, so that the message can be acquired from the memory area and processed. Specifically, the consuming side may process the message according to the message processing method 300 described later.
Next, a method of processing a message executed in the consumer side will be described.
Fig. 3 shows a flow diagram of a method 300 of processing a message according to another embodiment of the invention. The method 300 may be performed in an operating system of a computing device, such as the computing device 100 described above. The operating system may be any operating system, such as: windows, linux, unix, but is not so limited. The computing device executing the method 300 includes a producer side and a consumer side, wherein the producer side may also be referred to as a producer process and the consumer side may also be referred to as a consumer process. The method 300 is suitable for execution in a consuming side of a computing device, such as the computing device 100 described above. As shown in fig. 3, the method 300 begins at step 310.
In step 310, a memory area shared by the consuming side and the producing side is created, and a semaphore for inter-process communication between the consuming side and the producing side and a semaphore for inter-thread communication between a plurality of message processing threads of the consuming side are initialized.
According to the embodiment of the invention, after the consumption end creates the memory area shared by the consumption end and the production end, the consumption end and the production end initialize the semaphore of interprocess communication together. The semaphore for interprocess communication may be used to indicate the number of resources that are allowed to be accessed, and may be set to 0 when the semaphore for interprocess communication is initialized, indicating that no resources are accessible. In addition, it is also necessary to initialize the semaphore of inter-thread communication between multiple message processing threads of the consuming side, which can be used to control the access of resources, i.e. to control the access of messages in the memory area, and which can indicate the amount of common resources that are not used by the threads. During the initialization of the semaphore for inter-thread communication, the semaphore for inter-thread communication may be set to the amount of resources that are currently available for inter-thread communication, for example: the number of messages currently counted by the thread.
In some embodiments, the size of the largest data structure unit of the computing device is obtained and the size of the memory region is adjusted to be an integer multiple of the size of the largest data structure unit.
Specifically, the communication protocol for interprocess communication between the production side and the consumption side comprises the structural units, and the size of the maximum data structural unit can be obtained by comparing all the structural units involved in the communication protocol. Alternatively, the size of the maximum data structure unit may be the size of a memory page.
In some embodiments, in the memory area, a circular queue structure variable shared by the consumer side and the producer side is created, so as to handle a read-write process of a message through the created circular queue structure variable, for example: the production end is responsible for writing the message into the circular queue structure variable, and the consumption end is responsible for reading the message from the circular queue structure variable. Optionally, in the memory area, the consuming side maps the memory area of the target file, so that the consuming side can directly access the target file corresponding to the address of the memory area of the target file, and record the message through the target file.
In step 320, a plurality of message processing threads are created and initiated by the consumer.
According to the embodiment of the invention, the plurality of message processing threads can comprise a message acquisition thread, a message analysis thread and/or a message cache length listening thread, and a message consumption thread. The message obtaining thread may be configured to obtain a message generated by a production end. The message parsing thread may be configured to parse the message acquired in the message acquisition thread, for example: and splitting the acquired message. The message consumption thread may be used to perform some additional processing on the parsed message, such as: and printing the analyzed message. A message cache length snoop thread may be used to snoop for the presence of messages in the cache.
In step 330, the message written into the memory area by the producer is processed by the plurality of message processing threads according to the incoming parameters, wherein the incoming parameters include the semaphore of the interprocess communication and the semaphore of the inter-thread communication.
The following describes a flow of processing a message by each of a plurality of message processing threads.
FIG. 4 illustrates a flow diagram for a message fetch thread processing a message in accordance with one embodiment of the present invention. As shown in fig. 4, in step 410, the length of the message stored in the memory area is obtained through the message obtaining thread.
Specifically, when a message is sent, the number of messages will be accumulated, and the length of the message will also be accumulated, and when a message is received, the number of messages will be decremented, and the length of the message will also be decremented. Optionally, the length of the message stored in the memory unit of the memory area is obtained.
Subsequently, in step 420, the message stored in the memory area is obtained according to the length of the message.
Specifically, according to the length of the message stored in the acquired memory area, the message of the length in the memory area is acquired, that is, the message stored in the entire memory area is acquired as a whole.
Then, in step 430, the message stored in the memory area is stored in the first cache area shared by the message obtaining thread and the message parsing thread.
In some embodiments, the message obtaining thread also stores the message stored in the memory area into a third cache area shared by the message obtaining thread and the message buffer length listening thread, so that the message buffer length listening thread processes the message stored in the shared third cache area.
Here, the first cache region and the third cache region exist in the computing device and independently exist outside a memory region shared by the production side and the consumption side.
Then, in step 440, the semaphore of the inter-thread communication is updated, so that the message parsing thread splits the message stored in the first buffer according to the updated semaphore of the inter-thread communication.
According to an embodiment of the invention, the semaphore for inter-thread communication is the number of messages currently counted by a thread. And updating the semaphore of the inter-thread communication, namely updating the semaphore of the inter-thread communication to be in a latest state and updating the semaphore of the inter-thread communication to be the number of the messages which are currently counted by the message acquisition thread.
Subsequently, in step 450, when the length of the message stored in the memory area is zero, the memory area is monitored.
According to the embodiment of the invention, when the length of the message stored in the memory area is zero, it can indicate that no message is stored in the memory, and at this time, the memory area is monitored, so that when the message exists in the memory area, the message is continuously processed.
Then, in step 460, in response to the change in the semaphore for interprocess communication, the steps from acquiring the length of the message stored in the memory area are continued.
According to the embodiment of the invention, when the semaphore of the interprocess communication changes, which indicates that the resource in the memory area accessible by the consumer terminal changes, and the accessible message exists in the memory area, the steps in 410-460 are continuously executed.
FIG. 5 illustrates a flow diagram for a message parsing thread to process a message according to one embodiment of the invention. As shown in fig. 5, in step 510, it is determined whether or not the updated semaphore for inter-thread communication is accounted for by the message analysis thread.
Subsequently, in step 520, if the updated semaphore for inter-thread communication accounts for a message, the message stored in the first buffer is split and then stored in a second buffer shared by the message analysis thread and the message consumption thread, the split message stored in the second buffer is counted, and the updated semaphore for inter-thread communication is updated again, so that the message consumption thread performs predetermined processing on the split message stored in the second buffer according to the updated semaphore for inter-thread communication.
The second cache region exists in the computing device and independently exists outside a memory region shared by the production end and the consumption end.
In some embodiments, the message stored in the first cache may be split according to a specific length, for example, the message stored in the first cache may be split into a plurality of messages of specific lengths, so as to split a large message into a plurality of small messages. Of course, the message may be split according to other ways, which is not limited by the present invention.
According to an embodiment of the invention, the semaphore for inter-thread communication is the number of messages that a thread is currently counting. And updating the semaphore of the inter-thread communication, namely updating the semaphore of the inter-thread communication to be in a latest state and updating the semaphore of the inter-thread communication to be the number of the split messages counted by the message analysis thread currently.
If the updated semaphore for inter-thread communication does not account for a message, step 530 is executed to suspend the message resolution thread and release the system resources occupied by the message resolution thread.
FIG. 6 illustrates a flow diagram for a message consuming thread processing a message according to one embodiment of the invention. As shown in fig. 6, in step 610, it is determined whether or not the semaphore for the thread-to-thread communication updated again counts up a message by the message consuming thread.
If the updated semaphore for inter-thread communication counts a message, step 620 is executed to perform predetermined processing on the split message stored in the second buffer.
In some embodiments, performing the predetermined processing on the split messages stored in the second buffer area may be printing the split messages stored in the second buffer area one by one.
If the updated semaphore for inter-thread communication does not account for a message, step 630 is performed, the message consuming thread is suspended, and system resources occupied by the message consuming thread are released.
FIG. 7 illustrates a flow diagram for a message cache length snoop thread processing a message according to one embodiment of the present invention. As shown in fig. 7, in step 710, the length of the message stored in the third buffer is printed by the message buffer length listening thread.
Subsequently, in step 720, the message buffer length listening thread is put to sleep for a predetermined time.
In some embodiments, the predetermined time period may be set as desired, for example: the predetermined time period may be 1 second, but the predetermined time period may be set to other time periods. Here, the purpose of sleeping the message buffer length listening thread for a predetermined time is to facilitate statistics of packet loss that may exist in multi-threaded message passing, and to alleviate the bandwidth problem.
Subsequently, in step 730, after the sleep of the message buffer length monitoring thread is finished, the length of the message stored in the third buffer is monitored.
In some embodiments, the message cache length monitoring thread continuously monitors the messages stored in the third cache region, and when the length of the messages stored in the third cache region changes, the steps 710 to 730 are continuously executed, so as to conveniently count the length of the messages currently stored in the third cache region.
In some embodiments, after step 330 of method 300, multiple message processing threads may also be associated with the consuming side's main thread. Optionally, the aforementioned multiple message processing threads are associated with the main thread of the consuming side in a blocking manner.
Subsequently, in response to the end of the plurality of message processing threads, the mapping of the storage area of the target file can be cancelled, and the storage area shared by the production end and the consumption end can be deleted.
In some embodiments, the number of each thread in the message obtaining thread, the message parsing thread, the message consuming thread, and the message cache length monitoring thread may also be allocated according to a system resource condition of the operating system, so as to increase the processing efficiency of the message and further improve the speed of inter-process communication between the producing end and the consuming end.
The invention also provides a message processing system. Fig. 8 shows a schematic diagram of a system 800 for processing messages according to an embodiment of the invention. As shown in fig. 8, a system 800 for processing messages includes a consumer end 810 and a producer end 820.
Wherein the consuming end 810 is adapted to: creating a memory area shared by a consumption end and a production end, and initializing semaphore for interprocess communication between the consumption end and the production end and semaphore for interprocess communication between a plurality of message processing threads of the consumption end; creating and starting a plurality of message processing threads; and processing the message written into the memory area by the production end through a plurality of message processing threads according to the incoming parameters, wherein the incoming parameters comprise the semaphore of interprocess communication and the semaphore of interprocess communication.
Wherein the production end 820 is adapted to: initializing a memory area shared by a production end and a consumption end and a semaphore for interprocess communication between the consumption end and the production end; acquiring a memory unit of a memory area; messages are written to the memory unit through multithreading and the semaphore for interprocess communication is updated.
It should be noted that, the details of the message processing system 800 provided in this embodiment have been disclosed in detail in the description based on fig. 1 to fig. 7, and are not described herein again.
According to the technical scheme, the memory area shared by the production end and the consumption end is created, so that the production end and the consumption end can access the memory area. The production end writes the message into the memory area, and the consumption end processes the message in the memory area, so that the production end and the consumption end do not need to directly transmit the message, but transmit the message in a mode of accessing the shared memory area, and the inter-process communication speed between the production end and the consumption end is improved. The invention also processes the message through a plurality of message processing threads, thereby improving the processing speed of the message and further improving the interprocess communication speed between the production end and the consumption end.
Furthermore, the invention acquires the message from the memory area through the message acquisition thread, splits the message acquired by the message acquisition thread through the message analysis thread, performs preset processing on the message split by the message analysis thread through the message consumption thread, monitors the length of the message acquired by the message acquisition thread through the message cache length monitoring thread, and completes the processing of the message through the cooperation of the threads, thereby improving the inter-process communication speed between the production end and the consumption end.
In addition, the technical scheme of the invention can be suitable for any operating system and has high flexibility. The number of each thread in a plurality of message processing threads can be allocated, so that the message processing efficiency is improved, and the speed of interprocess communication between the production end and the consumption end is further improved. The invention can realize high-speed communication among processes without complex boundary processing algorithm.
