Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present disclosure.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. The terms "comprises," "comprising," and the like, as used herein, specify the presence of stated features, steps, operations, and/or components, but do not preclude the presence or addition of one or more other features, steps, operations, or components.
All terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art unless otherwise defined. It is noted that the terms used herein should be interpreted as having a meaning that is consistent with the context of this specification and should not be interpreted in an idealized or overly formal sense.
In those instances where a convention analogous to "at least one of A, B, and C, etc." is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., "a system having at least one of A, B, and C" would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.).
In an application scene of video stream data transmission, a data acquisition end establishes long connection with a server. When an application program of a server is upgraded, a traditional method is that after the application program of the server is upgraded, a new main process closes a port of an atomic process, and a new sub-process is created to execute tasks related to a service request.
The inventor finds that: in this conventional manner, since the atomic process has already processed the task related to the service request through the access port before the application program of the server is upgraded, and the access port of the sub-process is closed after the application program is upgraded, the task related to the service request processed by the atomic process may have an abnormal termination problem.
In view of this, embodiments of the present disclosure provide a process creation method. The method comprises the technical means that state information of a first sub-process created by a first main process before application program upgrading is inquired, then identification information of a first port and task information to be executed of the first sub-process are obtained from a target database through a second main process according to the state information of the first sub-process, and then the second main process creates a second sub-process according to the identification information of the first port and the task information to be executed of the first sub-process. After the application program is upgraded, the second main process is the second sub process established according to the port of the first sub process and the task information to be executed of the first sub process, so that the second sub process can continue to execute the task to be executed of the first sub process by accessing the first port, the technical problem that the service request before the application program is upgraded is abnormally terminated and abnormally terminated is at least partially solved, and the technical effect that the second sub process established after the application program is upgraded can continue to execute the task to be executed by accessing the first port before the application program is upgraded is achieved.

Fig. 2 schematically shows a flow chart of a process creation method according to an embodiment of the present disclosure.
As shown in fig. 2, the method includes operations S210 to S240.
In operation S210, a second host process for processing a service request associated with an application program is created in response to an upgrade operation of the application program.
According to an embodiment of the present disclosure, the application program may include a streaming media application program, such as: various types of video and audio playback applications, video interaction applications, and the like. The service request associated with the application may include a service request related to a streaming media service, such as: video screenshots, and the like.
In operation S220, state information of a first sub-process is queried by a second host process, wherein the first sub-process is created by the first host process before the application upgrade, and the state information of the first sub-process characterizes a state of a task performed by the first sub-process by accessing the first port before the application upgrade.
According to the embodiment of the disclosure, taking a video screenshot service request as an example, before an application program is upgraded, a server keeps a long connection with an acquisition end, and a first main process creates a first sub-process and executes a task of video screenshot by accessing a first port. The second main process may acquire the state information of the first sub-process by querying the monitoring information of the first main process. The first sub-process's body information may also be stored in a shared memory or a target database.
In operation S230, when the state information of the first sub-process satisfies the preset condition, the second main process obtains, according to the state information of the first sub-process, the identification information of the first port and the to-be-executed task information of the first sub-process from the target database.
According to an embodiment of the present disclosure, the preset condition may be that the state information of the first sub-process is "unprocessed" or "in processing", which means that the state of the task executed by the first sub-process by accessing the first port before the application program is upgraded is "unprocessed" or "in processing". For example: port a is the port where the server establishes a long connection with the client. The task executed by the first sub-process through the access port a may be a video capture task, and when the application program is upgraded, the video stream data received by the first sub-process from the client through the access port a may be only a part of the video stream data, that is, the video stream data is not downloaded to the whole video stream data.
According to the embodiment of the disclosure, the port identification information, the to-be-executed task information of the first sub-process, and the identification information of the first sub-process may be stored in the target database. The information of the task to be executed of the first sub-process may be marked with a file identifier in the target database. For example: the second main process may obtain, from the target database, the identification information of the port a and the information of the video screenshot task to be executed by the first sub-process, according to the identification information of the first sub-process, when the state information of the first sub-process satisfies the preset condition.
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.
According to an embodiment of the present disclosure, for example: and creating a second subprocess through the second main process according to the identification information of the port A and the information of the video screenshot task to be executed of the first subprocess. Because the second sub-process multiplexes the port A, the information of the video screenshot task to be executed of the first sub-process can be continuously executed through the access port A, that is, another part of video stream data is continuously downloaded through the access port A, and the video screenshot task is completed.
According to the embodiment of the disclosure, a technical means is adopted for creating the state information of the first sub-process by querying the first main process before the application program is upgraded, then obtaining the identification information of the first port and the task information to be executed of the first sub-process from the target database through the second main process according to the state information of the first sub-process, and then creating the second sub-process through the second main process according to the identification information of the first port and the task information to be executed of the first sub-process. After the application program is upgraded, the second main process is the second sub process established according to the port of the first sub process and the information of the task to be executed of the first sub process, so that the second sub process can continue to execute the task to be executed of the first sub process by accessing the first port, the technical problem that the service request before the application program is upgraded is abnormally terminated is at least partially solved, and the technical effect that the second sub process established after the application program is upgraded can continue to execute the task to be executed by accessing the first port before the application program is upgraded is achieved.
According to an embodiment of the present disclosure, the process creating method further includes:
responding to a service request initiated by a client after the application program is upgraded, and determining a second port through a second main process according to port occupation state information of each port in a target database;
and creating a third sub-process according to the second port and the service request through the second main process, wherein the third sub-process is used for executing the task responding to the service request.
According to an embodiment of the present disclosure, the occupancy state information of each port may be stored in the target database. And determining the second port by the second main process according to the port occupation state information of each port in the target database. For example: the target database comprises a port A, a port B and a port C. The port occupation state of the port A is an occupation state, the port occupation state of the port B is an occupation state, and the port occupation state of the port C is an idle state. The second port determined by the port with the idle state can be directly determined, that is, the port C is determined as the second port.
According to an embodiment of the present disclosure, for example: the service request initiated by the client after the application upgrade may be a video stream download task. The second main process may use a port in the idle state occupied by the port 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 a task of downloading the video stream through the access port C.
According to the embodiment of the disclosure, for the service request initiated by the client after the application program is upgraded, the port in the idle state can be used as an access port for processing the task associated with the service request by inquiring the port occupation state in the target database, so that the problem of abnormal termination of the service request caused by port conflict caused by the application program upgrading can be effectively avoided.
According to an embodiment of the present disclosure, determining, by a second host process, a second port according to port occupation state information of each port in a target database in response to a service request initiated by a client after an application program is upgraded, includes:
in response to a service request initiated by a client after application program upgrading, inquiring port occupation state information of each port from a target database through a second main process;
and determining the port with the idle state information as the second port.
According to an embodiment of the present disclosure, for example: the service request initiated by the client after the application program is upgraded may be a video stream downloading task, and the port occupation state information queried from the target database by the second host process may be: the port occupation state information of the port A is an occupation state, the port occupation state information of the port B is an idle state, and the port occupation state information of the port C is an occupation state.
According to the embodiment of the present disclosure, the port B whose port occupation state information is the idle state may be taken as the second port.
According to the embodiment of the disclosure, for the service request initiated by the client after the application program is upgraded, the port in the idle state can be used as an access port for processing the task associated with the service request by inquiring the port occupation state in the target database, so that the problem that the task processed by the atomic process is forced to be interrupted because the ports of the subprocess before the application program is upgraded are all closed in the traditional mode is solved, and the problem of port conflict caused by the application program upgrading is also solved.
According to an embodiment of the present disclosure, the process creation method further includes:
determining the port with the port occupation state information as an occupation state as a third port;
and changing the port occupation state information of the third port according to the occupied duration of the third port.
According to the embodiment of the disclosure, when the port is abnormally closed, the second host process or the first host process cannot update the port occupation state information in the target database in time, which may cause the port occupation state information of the abnormally closed port to be in an occupation state for a long time, so that the port cannot be normally multiplexed. Therefore, the occupied time of the port can be inquired, and the occupied state information of the port can be changed in time.
According to the embodiment of the disclosure, the second master process may query the occupied duration of the port in the occupied state from the target database by executing the timing task. For example, the occupied duration of a port in an occupied state may be queried every 10 s. A maximum threshold for the occupied duration may be set as the port maximum lifetime duration, for example: the occupied time of the port A is 10min, the occupied time of the port B is 45min, and the maximum survival time of the port is 15min. The occupied duration of the port B is longer than the maximum survival duration of the port, the port B can be determined to be an abnormal closed port, and the port occupied state of the port B is changed into an idle state, so that the second main process can multiplex the port B to create a new sub-process.
According to the embodiment of the disclosure, the occupied duration of the port in the occupied state is inquired, the occupied state information of the port is changed in time, and the problem that the port is blocked from being reused due to the fact that the port is abnormally closed and the occupied state of the port cannot be updated in time can be solved.
According to the embodiment of the present disclosure, changing the port occupation state information of the third port according to the occupied duration of the third port includes:
acquiring the time information of two adjacent occupied times of the third port from a target database;
calculating the occupied time length of the third port according to the information of the time when the third port is occupied twice;
and under the condition that the occupied duration of the third port exceeds a preset threshold value, changing the port occupation state information of the third port into an idle state.
According to an embodiment of the present disclosure, the second main advanceThe program or first host process may record in the target database the start and end timestamps for which the port is occupied when the port is occupied. The time information of the third port which is occupied twice can be the start time timestamp information of the third port which is occupied for the nth time, the start time timestamp information of the third port which is occupied for the (n-1) th time, the end time timestamp information of the third port which is occupied for the nth time and the end time timestamp information of the third port which is occupied for the (n-1) th time. For example: the time stamp information of the start time of the nth occupied port A is t1The time stamp information of the n-1 th occupied starting time is t2The time information of two adjacent occupied times of the third port can be t1、t2. The time stamp information of the termination time of the n-th occupied port A is t3The time stamp information of the n-1 th occupied termination time is t4The time information of two adjacent occupied times of the third port can be t3、t4。
According to the embodiment of the disclosure, according to the information of the time when the third port is occupied twice, calculating the occupied time length of the third port can be the difference t between the timestamps of the starting time when the third port is occupied twice1-t2The time stamp difference t may be the time stamp difference between the end times of two adjacent occupied third ports3-t4。
According to an embodiment of the present disclosure, the preset threshold may be a preset port maximum survival time Δ tmaxWhen t is1-t2Or t3-t4Greater than Δ tmaxIn this case, it may be determined that the port is abnormally closed, and the port occupation state information of the port may be changed to an idle state, so as to be used by other subprocesses.
According to the embodiment of the disclosure, the occupied time length of the port is determined according to the time information of two adjacent occupied times of the port, the occupied state information of the port is changed into the idle state under the condition that the occupied time length of the port exceeds the preset threshold value, so that other subprocesses can use the occupied state information, and the idle port is released in time to be used by other subprocesses under the condition that the port resources are limited, so that the purpose of fully utilizing the limited port resources on the premise of avoiding port conflicts is achieved.

In operation S301, in response to a service request initiated by a client after an application program is upgraded, port occupation state information of each port is queried from a target database through a second host process;
in operation S302, determining whether a port occupation state of a port is an idle state, and if so, performing operation S303; if not, operation S305 is performed.
In operation S303, determining the port whose port occupation state information is an idle state as a second port;
in operation S304, creating, by the second main process, a third sub-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;
in operation S305, determining the port of which the port occupation state information is an occupation state as a third port;
in operation S306, time information of two adjacent times of the third port being occupied is obtained from the target database;
in operation S307, an occupied duration of the third port is calculated according to information of two adjacent occupied times of the third port;
in operation S308, it is determined whether the occupied duration of the third port is greater than a preset threshold, if so, operation S309 is performed, and if not, operation S310 is performed.
In operation S309, the port occupation state information of the third port is changed to an idle state for use by other child processes.
In operation S310, no processing is performed.
According to an embodiment of the present disclosure, the process creating method further includes:
under the condition that the state information of the first sub-process does not meet the preset condition, closing the first sub-process through the second main process;
according to the port identification information of the first port, inquiring the port occupation state information of the first port from the target database;
and changing the port occupation state information of the first port into an idle state.
According to an embodiment of the present disclosure, the preset condition may be that the state information of the first sub-process is "unprocessed" or "in-process", which means that the state of executing the task by accessing the first port by the first sub-process before the application program is upgraded is "unprocessed" or "in-process". The state information of the first sub-process does not meet the preset condition, and the state of the first sub-process executing the task by accessing the first port can be 'finished'. For example: port a is the port where the server establishes a long connection with the client. The task executed by the first sub-process through the access port a can be a video screenshot task, and when the application program is upgraded, the first sub-process receives all video stream data from the client through the port a and completes the video screenshot task.
According to the embodiment of the disclosure, the first sub-process can be closed through the second main process, the identification information of the first port can be inquired from the target database, and the port occupation state information of the first port is changed into the idle state for other sub-processes to use. For example: the state information of the first sub-process is "completed", and the processing task executed by the port a during the first sub-process is accessed, the identification information of the port a can be inquired from the target database, and the port occupation state information of the port a is changed from the occupation state to the idle state.
According to the embodiment of the disclosure, the access port of the subprocess which has completed the processing task is closed in time for use by other subprocesses by querying the state information of the first subprocess, and the idle port is released in time for use by other subprocesses under the condition of limited port resources, so that the limited port resources are fully utilized on the premise of avoiding port conflict.
Fig. 4 schematically illustrates a storage format of port occupation state information in a target database according to an embodiment of the present disclosure.
As shown in fig. 4, a plurality of storage formats may be set in the target database, and the first addresses for storing the plurality of storage formats are mapped to the elements of the storage format pointer array. Each storage format is provided with an index, which may be 0,1, 2, 3.. N, respectively, each index may represent a relative value of a port identification, for example: the starting port may be 9000, and if the subscript of the storage format is 3, it may indicate that the storage format stores the port occupation state information of the port identified as 9003.
