[0044] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. It is to be understood, however, that the description is merely exemplary of the present disclosure, and is not intended to limit the scope of the present disclosure. In the following detailed description of the embodiments of the present disclosure, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure. However, it would be apparent to one skilled in the art that the present disclosure can be practiced without these specific details. In other instances, well-known structures and functions have not been described in detail in order to avoid obscuring aspects of the present disclosure.

[0045] The terms used herein are merely used to describe specific embodiments, and are not intended to limit the present disclosure. The terms "include" and "have" and the like used herein indicate the presence of the described features, steps, operations, and / or components, but do not preclude the presence or addition of one or more other features, steps, operations, or components.

[0046] All terms used herein, including technical and scientific terms, have the same meanings as those generally understood by those skilled in the art unless otherwise defined. It should be noted that the terms used herein should be interpreted as having meanings consistent with the context of the present specification, and should not be interpreted in an idealized or excessively formal manner.

[0047] In the event that a phrase such as "at least one of A, B, and C, etc." is used herein, it is intended that the phrase be interpreted to mean that an "A" alone is possible, a "B" alone is possible, a "C" alone is possible, "A" and "B" in combination are possible, "A" and "C" in combination are possible, "B" and "C" in combination are possible, or "A," "B," and "C" in combination are possible, etc.

[0048] In the application scenario of video stream data transmission, the data collection end establishes a long connection with the server. When the application program of the server is upgraded, the traditional way is that after the application program of the server is upgraded, the new master process closes the port of the atomic process, and creates a new child process to execute the task related to the service request.

[0049] The inventors have found that in this traditional way, because before the application program of the server is upgraded, the atomic process has handled the task related to the service request by accessing the port, after the application program is upgraded, the access port of the child process is closed, and the task related to the service request handled by the atomic process will be abnormally terminated.

[0050] Therefore, the embodiments of the present disclosure provide a process creation method. The method comprises querying state information of a first child process created by a first master process before an application program is upgraded, then acquiring identification information of a first port and to-be-executed task information of the first child process from a target database according to the state information of the first child process by a second master process, and creating a second child process according to the identification information of the first port and the to-be-executed task information of the first child process by the second master process. Because after the application program is upgraded, the second child process is created by the second master process according to the port of the first child process and the to-be-executed task information of the first child process, the second child process can continue to execute the to-be-executed task of the first child process by accessing the first port, so that at least part of the technical problems of abnormal termination of service request before the application program is upgraded are overcome, and the technical effect that the second child process created after the application program is upgraded can continue to execute the to-be-executed task by accessing the first port before the application program is upgraded is achieved.

[0051] Figure 1 An exemplary system architecture 100 to which the process creation method according to the embodiments of the present disclosure can be applied is schematically shown. It should be noted that, Figure 1 The shown is only an example of the system architecture to which the embodiments of the present disclosure can be applied, to help those skilled in the art understand the technical content of the present disclosure, but does not mean that the embodiments of the present disclosure cannot be used in other devices, systems, environments or scenarios.

[0052] As Figure 1As shown, the system architecture 100 according to this embodiment can include terminal devices 101, 102, 103, a network 104, and a server 105. The network 104 is a medium for providing communication links between the terminal devices 101, 102, 103 and the server 105. The network 104 can include various connection types, such as wired and / or wireless communication links, and the like.

[0053] A user can use the terminal devices 101, 102, 103 to interact with the server 105 through the network 104 to receive or send messages, and the like. Various communication client applications can be installed on the terminal devices 101, 102, 103, such as shopping applications, web browser applications, search applications, instant messaging tools, email clients, and / or social platform software, and the like (only as examples).

[0054] The terminal devices 101, 102, 103 can be various electronic devices with display screens and supporting web browsing, including but not limited to smart phones, tablet computers, laptop computers, desktop computers, and the like.

[0055] The server 105 can be a server providing various services, such as a background management server providing support for websites browsed by users using the terminal devices 101, 102, 103 (only as an example). The background management server can analyze and process received user requests and the like, and feed back the processing results (such as web pages, information, or data, and the like obtained or generated according to user requests) to the terminal devices.

[0056] It should be noted that the process creation method provided by the embodiments of the present disclosure can generally be executed by the server 105. Accordingly, the process creation system provided by the embodiments of the present disclosure can generally be arranged in the server 105. The process creation method provided by the embodiments of the present disclosure can also be executed by a server or a server cluster different from the server 105 and capable of communicating with the terminal devices 101, 102, 103 and / or the server 105. Accordingly, the process creation system provided by the embodiments of the present disclosure can also be arranged in a server or a server cluster different from the server 105 and capable of communicating with the terminal devices 101, 102, 103 and / or the server 105.

[0057] It should be understood that Figure 1 The number of terminal devices, networks, and servers in the system architecture 100 is only illustrative. According to the needs of implementation, there can be any number of terminal devices, networks, and servers.

[0058] Figure 2 A flowchart of a process creation method according to an embodiment of the present disclosure is schematically shown.

[0059] As Figure 2As shown, the method includes operations S210-S240.

[0060] In operation S210, in response to an upgrade operation of an application, a second master process for processing a service request associated with the application is created.

[0061] According to an embodiment of the present disclosure, the application can include a streaming media application, such as various types of audio and video playing applications, video interactive applications, and the like. The service request associated with the application can include a service request related to a streaming media service, such as a video screenshot, and the like.

[0062] In operation S220, the second master process queries state information of the first sub-process, wherein the first sub-process is created by the first master process before the application is upgraded, and the state information of the first sub-process represents a state of performing a task by the first sub-process through accessing the first port before the application is upgraded.

[0063] According to an embodiment of the present disclosure, taking a video screenshot service request as an example, before the application is upgraded, the server maintains a high-concurrency long connection with a collection end, and the first master process creates the first sub-process to perform a video screenshot task by accessing the first port. The second master process can obtain the state information of the first sub-process by querying the listening information of the first master process. The state information of the first sub-process can also be stored in a shared memory or a target database.

[0064] In operation S230, in a case where the state information of the first sub-process satisfies a preset condition, the second master process obtains identification information of the first port and to-be-executed task information of the first sub-process from the target database according to the state information of the first sub-process.

[0065] According to an embodiment of the present disclosure, the preset condition can be that the state information of the first sub-process is “unprocessed” or “processing”, indicating that the state of performing a task by the first sub-process through accessing the first port before the application is upgraded is “unprocessed” or “processing”. For example, port A is a port through which the server establishes a long connection with a client. The task performed by the first sub-process through accessing port A can be a video screenshot task, and when the application is upgraded, the video stream data received by the first sub-process from the client through port A can be only a part of the video stream data, i.e., not all of the video stream data is downloaded.

[0066] According to an embodiment of the present disclosure, the target database can store port identification information, to-be-executed task information of the first sub-process, and identification information of the first sub-process. The to-be-executed task information of the first sub-process can be marked with a file identifier in the target database. For example, the second main process can obtain, from the target database, identification information of the port A and video screenshot task information to be executed by the first sub-process according to the identification information of the first sub-process in a case where the state information of the first sub-process satisfies the preset condition.

[0067] In operation S240, a second sub-process is created by the second main process according to the identification information of the first port and the to-be-executed task information of the first sub-process, so that the second sub-process continues to execute the to-be-executed task of the first sub-process by accessing the first port.

[0068] According to an embodiment of the present disclosure, for example, the second sub-process can be created by the second main process according to the identification information of the port A and the video screenshot task information to be executed by the first sub-process. Since the second sub-process reuses the port A, the second sub-process can continue to execute the video screenshot task information to be executed by the first sub-process by accessing the port A, that is, continue to download another part of the video stream data by accessing the port A and complete the video screenshot task.

[0069] According to an embodiment of the present disclosure, because the technical means of querying the state information of the first sub-process created by the first main process before the application program is upgraded, then obtaining the identification information of the first port and the to-be-executed task information of the first sub-process from the target database by the second main process according to the state information of the first sub-process, and then creating the second sub-process by the second main process according to the identification information of the first port and the to-be-executed task information of the first sub-process is adopted. Since the second sub-process is created by the second main process according to the port of the first sub-process and the to-be-executed task information of the first sub-process after the application program is upgraded, the second sub-process can continue to execute the to-be-executed task of the first sub-process by accessing the first port, so that the technical problem of abnormal termination of the service request before the application program is upgraded is at least partially overcome, and the technical effect that the second sub-process created after the application program is upgraded can continue to execute the to-be-executed task by accessing the first port before the application program is upgraded is achieved.

[0070] According to an embodiment of the present disclosure, the process creation method further includes:

[0071] In response to a service request initiated by a client after the application program is upgraded, a second port is determined by the second main process according to the port occupation state information of each port in the target database.

[0072] A third sub-process is created by the second main process according to the second port and the service request, wherein the third sub-process is used to execute a task in response to the service request.

[0073] According to an embodiment of the present disclosure, the target database can store the occupation state information of each port. The second port can be determined by the second master process according to the port occupation state information of each port in the target database. For example, the target database includes port A, port B, and port C. The port occupation state of port A is occupied, the port occupation state of port B is occupied, and the port occupation state of port C is idle. The second port can be determined directly from the port with an idle state, that is, port C is determined as the second port.

[0074] According to an embodiment of the present disclosure, for example, the service request initiated by the client after the application upgrade can be a video stream download task. The second master process can take the port with an idle state in the target database as the second port, and then create a third sub-process according to the service request, so that the third sub-process executes the video stream download task by accessing port C.

[0075] According to an embodiment of the present disclosure, for the service request initiated by the client after the application upgrade, the port with an idle state can be taken as an access port for processing a task associated with the service request by querying the port occupation state in the target database, which can effectively avoid the problem of abnormal termination of the service request caused by the port conflict during the application upgrade.

[0076] According to an embodiment of the present disclosure, in response to the service request initiated by the client after the application upgrade, the second port is determined by the second master process according to the port occupation state information of each port in the target database, comprising:

[0077] In response to the service request initiated by the client after the application upgrade, the second master process queries the port occupation state information of each port from the target database;

[0078] The port with an idle state in the port occupation state information is determined as the second port.

[0079] According to an embodiment of the present disclosure, for example, the service request initiated by the client after the application upgrade can be a video stream download task, and the port occupation state information queried by the second master process from the target database can be: the port occupation state information of port A is occupied, the port occupation state information of port B is idle, and the port occupation state information of port C is occupied.

[0080] According to an embodiment of the present disclosure, the port B with an idle state in the port occupation state information can be taken as the second port.

[0081] According to the embodiment of the present disclosure, for the service request initiated by the client after the application upgrade, the idle port can be taken as the access port for processing the task associated with the service request by querying the port occupation state in the target database, which not only solves the problem that the tasks processed by the atomic process are forced to be interrupted due to the closing of all the ports of the sub-process before the application upgrade in the traditional way, but also solves the problem of port conflict caused by the application upgrade.

[0082] According to the embodiment of the present disclosure, the process creation method further includes:

[0083] The port with the port occupation state information in the occupied state is determined as a third port;

[0084] The port occupation state information of the third port is changed according to the occupied duration of the third port.

[0085] According to the embodiment of the present disclosure, since the second master process or the first master process cannot update the port occupation state information in the target database in time when the port is abnormally closed, the port occupation state information of the abnormally closed port may be in the occupied state for a long time, so that the port cannot be normally reused. Therefore, the occupied duration of the port can be queried to change the occupation state information of the port in time.

[0086] According to the embodiment of the present disclosure, the second master process can query the occupied duration of the port in the occupied state from the target database by executing a timing task. For example, the occupied duration of the port in the occupied state can be queried every 10s. A maximum threshold of the occupied duration can be set as a maximum survival duration of the port, for example, the occupied duration of port A is 10min, the occupied duration of port B is 45min, and the maximum survival duration of the port is 15min. Since the occupied duration of port B is greater than the maximum survival duration of the port, port B can be determined as an abnormally closed port, and the port occupation state of port B is changed to the idle state, so that the second master process can reuse port B to create a new sub-process.

[0087] According to the embodiment of the present disclosure, by querying the occupied duration of the port in the occupied state and changing the occupation state information of the port in time, the problem that the port reuse is hindered due to the failure of updating the port occupation state in time caused by the abnormal closing of the port can be solved.

[0088] According to the embodiment of the present disclosure, the port occupation state information of the third port is changed according to the occupied duration of the third port, including:

[0089] The time information of the adjacent two occupations of the third port is obtained from the target database;

[0090] According to the time information of the third port being occupied for two adjacent times, the occupied time length of the third port is calculated;

[0091] In the case where the occupied time length of the third port exceeds the preset threshold, the port occupation state information of the third port is changed to the idle state.

[0092] According to an embodiment of the present disclosure, the second main process or the first main process can record the start timestamp and the end timestamp of the port being occupied in the target database when the port is occupied. The time information of the third port being occupied for two adjacent times can be the start time stamp information of the third port being occupied for the nth time and the start time stamp information of the third port being occupied for the n-1th time, or the end time stamp information of the third port being occupied for the nth time and the end time stamp information of the third port being occupied for the n-1th time. For example, the start time stamp information of the third port being occupied for the nth time is t1, the start time stamp information of the third port being occupied for the n-1th time is t2, and the time information of the third port being occupied for two adjacent times can be t1 and t2. The end time stamp information of the third port being occupied for the nth time is t3, the end time stamp information of the third port being occupied for the n-1th time is t4, and the time information of the third port being occupied for two adjacent times can be t3 and t4.

[0093] According to an embodiment of the present disclosure, according to the time information of the third port being occupied for two adjacent times, the occupied time length of the third port can be the difference t1-t2 between the start time stamps of the third port being occupied for two adjacent times, or the difference t3-t4 between the end time stamps of the third port being occupied for two adjacent times.

[0094] According to an embodiment of the present disclosure, the preset threshold can be a preset maximum survival time length Δt of the port max When t1-t2 or t3-t4 is greater than Δt max , it can be determined that the port has an abnormal closing condition, and the port occupation state information of the port can be changed to the idle state to facilitate the use of other child processes.

[0095] According to an embodiment of the present disclosure, according to the time information of the port being occupied for two adjacent times, the occupied time length of the port is determined, in the case where the occupied time length of the port exceeds the preset threshold, the port occupation state information of the port is changed to the idle state to facilitate the use of other child processes, in the case where the port resources are limited, the idle port is released in time for the use of other child processes, so as to achieve the purpose of fully utilizing the limited port resources on the premise of avoiding port conflicts.

[0106] In operation S309, changing the port occupancy state information of the third port to the idle state, so as to be used by other sub-processes.

[0107] In operation S310, no processing is performed.

[0108] According to embodiments of the present disclosure, the process creation method further includes:

[0109] In a case where the state information of the first sub-process does not satisfy a preset condition, closing, by the second master process, the first sub-process;

[0110] Querying, from the target database, port occupancy state information of the first port according to port identification information of the first port;

[0111] Changing the port occupancy state information of the first port to the idle state.

[0112] According to an embodiment of the present disclosure, the preset condition can be that the state information of the first sub-process is "unprocessed" or "processing", indicating that the state of the first sub-process performing a task by accessing the first port before the application program is upgraded is "unprocessed" or "processing". When the state information of the first sub-process does not satisfy the preset condition, the state of the first sub-process performing a task by accessing the first port can be "completed". For example, port A is a port for the server to establish a long connection with the client. The task performed by the first sub-process by accessing port A can be a video screenshot task. When the application program is upgraded, the first sub-process receives all video stream data from the client through port A and completes the video screenshot task.

[0113] According to an embodiment of the present disclosure, the first sub-process can be closed by the second main process. The identification information of the first port can be queried from the target database, and the port occupation state information of the first port can be changed to an idle state for use by other sub-processes. For example, when the state information of the first sub-process is "completed", the first sub-process performs a processing task by accessing port A, and the identification information of port A can be queried from the target database. The port occupation state information of port A is changed from an occupied state to an idle state.

[0114] According to an embodiment of the present disclosure, by querying the state information of the first sub-process, the access port of the sub-process that has completed the processing task is closed in time for use by other sub-processes. In the case of limited port resources, idle ports are released in time for use by other sub-processes, so as to fully utilize the limited port resources under the premise of avoiding port conflicts.

[0115] Figure 4 The storage format of the port occupation state information in the target database according to an embodiment of the present disclosure is schematically shown.

[0116] As shown in Figure 4 , a plurality of storage formats can be set in the target database, and the first addresses of the plurality of storage formats are mapped to each element of the storage format pointer array. Each storage format is provided with an index, and the indexes can be 0, 1, 2, 3...N respectively. Each index can represent a relative value of a port identification. For example, the starting port can be 9000. If the index of the storage format is 3, it can be indicated that the storage format stores the port occupation state information of the port with the port identification of 9003.
