[0042] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0043] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0044] Figure 1 This is a flow chart of a control method for a log output target proposed in the present application. The control method for the log output target can be executed by a control device for the log output target. The control device for the log output target can be implemented in the form of software and / or hardware and integrated into an electronic device, for example, can be specifically integrated into a vehicle controller.

[0045] like Figure 1 As shown, the control method of the log output target includes the following steps:

[0046] S110: Receive a request to change a log output target.

[0047] The log output target refers to the log output location, such as the console, remote server, or local file. For example, during the system debugging phase, in order to clearly and intuitively observe the real-time operating status of the system, you can choose to output the log to the console so that technicians can promptly discover and solve potential problems. During the normal operation of the system, in order to save storage space and improve system performance, you can choose to output the log to a local file or remote server. Therefore, it is of great significance to be able to flexibly adjust the log output target.

[0048] The change request of the log output target can be triggered by the host computer. Specifically, the technician can trigger the change request of the log output target according to the system operation status. For example, in the system debugging stage, in order to clearly and intuitively observe the real-time operation status of the system, the log can be output to the console so that the technician can find and solve potential problems in time. In the normal operation stage of the system, in order to save storage space and improve system performance, the log can be output to a local file or a remote server.

[0049] Alternatively, the change request of the log output target may be automatically triggered by automation means, for example, when a specific flag is detected, a change request of a matching log output target is triggered.

[0050] The change request of the log output target may specifically include an indicated target, that is, the log is expected to be output to a certain location, and the location is the indicated target. For example, the change request of the log output target is specifically "please output the log to a remote server", where "remote server" is the indicated target. This means that after this change, the log output target includes the remote server, that is, the log must be output to at least the remote server.

[0051] The change request of the log output target may also include a target to be changed, i.e., a target to be changed. For example, the change request of the log output target is specifically "please change the log output from the console to the remote server", wherein "console" is the target to be changed and "remote server" is the indicated target. This means that before this change, the log is output to the console, and after this change, the log is no longer output to the console, but to the remote server.

[0052] Furthermore, the request to change the log output target may include multiple indicated targets and multiple targets to be changed, so as to achieve flexible output of logs and multi-target output.

[0053] S120: modify the log output target list according to the modification request to obtain a modified log output target list.

[0054] In some embodiments, the log output target list is changed according to the change request to obtain the changed log output target list, including: parsing the change request to determine the target to be changed and the indicated target; deleting the target to be changed from the log output target list, and adding the indicated target to the log output target list. For example, the change request is "Please change the log output from the console to the remote server". By parsing the change request, it is identified that the "console" is the target to be changed and the "remote server" is the indicated target. Then, the log write path corresponding to the "console" recorded in the log output target list is deleted, and the log write path corresponding to the "remote server" is added to the log output target list to obtain the changed log output target list.

[0055] Exemplarily, adding the indicated target to the output target list and deleting the target to be changed from the output target list can be achieved through a custom function.

[0056] In other embodiments, the log output target list is changed according to the change request to obtain the changed log output target list, including: parsing the change request to determine the indicated target; adding the indicated target to the log output target list to obtain the changed log output target list. This embodiment corresponds to the scenario of adding a log output target, for example, the change request of the log output target is specifically "please output the log to a remote server", wherein "remote server" is the indicated target. This means that after this change, the log output target includes the remote server.

[0057] S130. Control log output according to the modified log output target list.

[0058] In some implementations, controlling log output according to the modified log output target list includes:

[0059] In response to receiving a log output request, the log is controlled to be output to each target recorded in the changed log output target list. Alternatively, one or more targets matching the log output request are determined from the changed log output target list; and the log is controlled to be output to the one or more targets. Thus, the purpose of dynamically changing the log output target is achieved.

[0060] The control method of the log output target disclosed in the embodiment of the present application maintains a log output target list and then controls the log output according to the log output target list, thereby achieving the purpose of dynamically controlling the log output target during system operation without the need for system restart, which is beneficial to improving system performance and efficiency.

[0061] On the basis of the above embodiment, this embodiment provides another method for controlling log output targets, specifically, optimizing the design of step S120 in the above embodiment, "changing the log output target list according to the change request to obtain the changed log output target list", with the purpose of ensuring the orderliness of changing the log output target list in a multi-threaded scenario, and avoiding multiple threads changing the log output target list at the same time, thereby causing a change conflict. In other words, the optimization design of this embodiment can improve the stability and reliability of the change of the log output target list, thereby improving the controllability and flexibility of the log output.

[0062] like Figure 2 As shown, the control method of the log output target includes the following steps:

[0063] S210: Receive a request to change a log output target.

[0064] S220: When the lock state of the log output target list is unlocked, modify the log output target list according to the modification request to obtain a modified log output target list.

[0065] Wherein, under the multithreading scene, in order to avoid having multiple threads to change the log output target list at the same time, thereby causing a conflict, before a thread changes the log output target list, the locking state of the log output target list is determined, if the locking state of the log output target list is in the case of being unlocked, the log output target list is changed according to the change request, and the changed log output target list is obtained. If the locking state of the log output target list is in the case of being locked (indicating that other threads are changing the log output target list at the current moment), the current thread then enters a dormant state, and waits to be awakened when the locking state of the log output target list jumps to an unlocked state.

[0066] Specifically, when a thread obtains the control authority of the log output target list (i.e., determines that the lock state of the log output target list is unlocked), when changing the log output target list, the lock state of the log output target list is set to "locked" to inform other threads that want to change the log output target list, so that other threads that want to change the log output target list enter a dormant state, so as to avoid multiple threads changing the log output target list at the same time, thereby causing a conflict. When the lock state of the log output target list jumps to "unlocked", the dormant thread is awakened so that it continues to operate on the log output target list. In this way, the orderliness of the changes to the log output target list is guaranteed in the multi-threaded scenario, and multiple threads are prevented from changing the log output target list at the same time, thereby causing a change conflict.

[0067] Wherein, the locking state of the log output target list can be realized by a condition variable or a mutex lock. Wherein, the mutex lock is used to ensure that the thread will not be interrupted by other threads when modifying shared data (i.e., the log output target list). The condition variable is used to wake up the thread when a certain condition is met. For example, a thread wants to change the log output target list. First, it obtains the mutex lock to ensure exclusive access to the log output target list, and sets the value of the condition variable "is_switching" to true to notify other threads that the log output target list is being occupied. When the log output target list is changed, the mutex lock is released, and the value of the condition variable "is_switching" is set to false to wake up other threads that are dormant because the value of the condition variable is true.

[0068] In summary, the log output target list is changed according to the change request to obtain the changed log output target list, including: when the value of the condition variable is a first preset value (indicating that the lock state of the log output target list is unlocked), acquiring a mutex lock, and setting the value of the condition variable to a second preset value (i.e., setting the lock state of the log output target list to be locked), and changing the log output target list according to the change request to obtain the changed log output target list. After the log output target list is changed according to the change request, the mutex lock is released, and the value of the condition variable is set to the first preset value, i.e., setting the lock state of the log output target list to be unlocked, so that other threads can continue to operate on the log output target list.

[0069] In some embodiments, the log output target list is changed according to the change request to obtain the changed log output target list, including: setting the lock state of the log output target list to locked, parsing the change request, determining the target to be changed and the indicated target; deleting the target to be changed from the log output target list, and adding the indicated target to the log output target list; setting the lock state of the log output target list to unlocked.

[0070] Alternatively, the log output target list is changed according to the change request to obtain the changed log output target list, including: setting the lock state of the log output target list to locked, parsing the change request to determine the indicated target; adding the indicated target to the log output target list to obtain the changed log output target list; setting the lock state of the log output target list to unlocked.

[0071] S230: When the lock state of the log output target list is locked, enter a dormant state, and wait to be awakened when the lock state of the log output target list changes to an unlocked state.

[0072] S240. Control log output according to the changed log output target list.

[0073] The control method of log output target provided in this embodiment optimizes the design of step S120 "changing the log output target list according to the change request to obtain the changed log output target list" in the above embodiment, specifically, when the lock state of the log output target list is unlocked, the log output target list is changed according to the change request to obtain the changed log output target list, and before changing the log output target list according to the change request, the lock state of the log output target list is set to be locked; after changing the log output target list according to the change request, the lock state of the log output target list is set to be unlocked. When the lock state of the log output target list is locked, enter the dormant state and wait to be awakened when the lock state of the log output target list jumps to the unlocked state. In a multi-threaded scenario, the orderliness of the change of the log output target list is guaranteed, and multiple threads are prevented from changing the log output target list at the same time, thereby causing a change conflict. The optimized design of this embodiment can improve the change stability and reliability of the log output target list, thereby improving the controllability and flexibility of log output.

[0074] On the basis of the above embodiment, this embodiment provides another method for controlling log output targets, specifically, optimizing the design of step S130 "controlling log output according to the modified log output target list" in the above embodiment, with the purpose of ensuring the orderliness of log output in a multi-threaded scenario, avoiding conflicts caused by multiple threads outputting logs at the same time, and causing inconsistent and confusing log information. In other words, the optimization design of this embodiment can improve the stability and reliability of log output, thereby improving the controllability and flexibility of log output.

[0075] like Figure 3 As shown, the control method of the log output target includes the following steps:

[0076] S310: Receive a request to change a log output target.

[0077] S320: Change the log output target list according to the change request to obtain a changed log output target list.

[0078] S330. In response to receiving a log output request, when the lock state of the log output target list is unlocked, control the log to be output to each target recorded in the changed log output target list; or, determine one or more targets that match the log output request from the changed log output target list.

[0079] That is, when a thread outputs logs, it is also necessary to determine the lock status of the log output target list at the current moment, that is, to determine whether there are other threads outputting logs at the current moment. If there are no other threads outputting logs, the current thread can output logs. If there are other threads outputting logs, the current thread cannot output logs. The current thread goes into sleep mode and waits to be awakened before executing the log output operation, thereby ensuring the orderliness, uniqueness and reliability of log output in multi-threaded scenarios.

[0080] Specifically, if there are no other threads that are outputting logs, the current thread can output logs, the current thread acquires a mutex lock, and sets the value of the condition variable to the second preset value (i.e., setting the lock state of the log output target list to be locked), the current thread starts to output logs, and after the output is completed, the mutex lock is released, and the value of the condition variable is set to the first preset value (i.e., setting the lock state of the log output target list to be unlocked), so as to wake up other threads that are dormant and enable other threads to continue to output logs. In a multi-threaded scenario, the orderliness of log output is guaranteed, and multiple threads are prevented from outputting logs at the same time, thereby causing conflicts and causing inconsistent and chaotic log information. In other words, the stability and reliability of log output can be improved through the optimized design of this embodiment, thereby improving the controllability and flexibility of log output.

[0081] On the basis of the above-mentioned embodiments, a control system for log output targets is provided, aiming to solve the problem that log output targets cannot be switched dynamically. The control system for log output targets provided by the present application allows the user to dynamically switch or recombine the output targets of the log according to different environmental conditions (such as system load, operating environment, user input, etc.) when the system is running, thereby improving the flexibility of the log system. The core of the present application is to create and manage different log output targets (sinks), which include different types of targets such as consoles, files, and remote servers. Specifically, according to the request of the dynamic control module (host computer), the switching of log output targets is controlled, and flexible combinations of multiple output targets such as consoles, files, and remote servers are supported, while ensuring that the logging operations being performed are not affected during the switching process. In addition, the present application also supports multi-threaded environments, which can avoid the loss of log data due to competition between threads. For example Figure 4As shown, the control system of the log output target provided by the present application includes the following four modules: a log management module 410 , a dynamic control module 420 , a configuration module 430 and a multi-threading module 440 .

[0082] The log management module 410 is mainly responsible for the following two points: when the system starts, it receives the initialization configuration of the APExe application process and specifies the default log output target, refresh frequency and other parameters. When the system is running, it receives the dynamic change request of the dynamic control module 420 (host computer), creates a new log output target in real time according to the dynamic change request, and adds it to the output target list, or removes the existing log output target from the output target list. At the same time, a safety mechanism is introduced to ensure that the log recording operation being executed will not be affected during the switching process, and the addition, deletion or recombination of the log output target is realized to achieve the purpose of dynamic control. Specifically, the log management module 410 can be further subdivided into the APExe application process and the manager. When the system starts, the APExe application process is responsible for loading the corresponding log configuration file, initializing the log output configuration, and receiving the change request of the log output target sent by the dynamic control module 420 when the system is running, parsing the request content, calling the specific output target change interface, and ensuring that the system's log output can be flexibly switched according to demand. The manager is implemented through a singleton, creates and manages different log output targets, performs operations such as adding, removing, and recombination of log output targets, and also realizes the initialization configuration of the log. Furthermore, the log output target list includes multiple log output targets.

[0083] The dynamic control module 420 is mainly connected to the system on chip SOC (System Of Chip) through the host computer. The client Client located in the host computer first initiates a connection request to connect to the server Server on the SOC. After the connection is completed, when the system is running, it can send a change request for the log output target according to the debugging requirements and the specific conditions of the system operation. For example, during the debugging stage, in order to be able to clearly and intuitively observe the real-time operating status of the system, it is necessary to output the log to the console so that technicians can discover and solve potential problems in a timely manner. When the system is running normally, in order to save storage space and improve system performance, the log is output to a file or a remote server.

[0084] The configuration module 430 can generate a corresponding log configuration according to the log configuration file log.conf. The log management module 410 creates a corresponding log output target according to the configuration module 430. When the system starts, the configuration file is loaded, and the initial configuration of the log is generated according to the content in the configuration file, and the default output target of the log is clearly specified, or the default output target is not set.

[0085] The multithreading module 440 implements a thread-safe dynamic switching mechanism for log output targets through conditional variables and mutexes. Log output operations and output target change operations are synchronized by mutexes and conditional variables to prevent multiple threads from accessing or modifying the output target at the same time. When a thread outputs a log, it first acquires a mutex. If other threads are modifying the output target, the current thread goes dormant and enters a waiting state. Waiting for wakeup can be achieved by conditional variables. This mechanism can ensure the correctness and data consistency of log output target switching in multithreaded scenarios, avoid multiple threads from outputting logs or modifying output targets at the same time, thereby causing conflicts, resulting in inconsistent and confusing log information, and can improve system stability and log management flexibility.

[0086] In some embodiments, reference is made to Figure 5 The flowchart of a control method for a log output target shown in FIG. 1 specifically includes the following steps:

[0087] S510: Request to change the log output target.

[0088] S520, check whether the log is being output or the log output target is being changed, if so, enter sleep mode and wait for wake-up, otherwise, acquire a mutex lock.

[0089] S530, entering sleep mode and waiting to be awakened.

[0090] S540: Acquire the mutex lock and set the condition variable to true.

[0091] S550: Change the log output destination.

[0092] S560. Release the mutex lock and set the condition variable to false.

[0093] In summary, the whole process is: system initialization, default loading of predefined log output target, and receiving log output target change request. When each thread performs log output operation, it first obtains the mutex lock to ensure exclusive access to the log output target. Only after obtaining the mutex lock can the thread perform log output operation. If the thread finds that the current log output target is being changed by other threads (it can be determined by detecting the condition variable is_switching whether the current log output target is being changed by other threads), the current thread enters the waiting state through the condition variable is_switching until it is awakened. Similarly, when a thread needs to change the log output target, it first obtains the mutex lock and sets the condition variable is_switching to true to notify other threads that there is currently a thread changing the output target. When the change is completed, the condition variable is_switching is set to false, and all waiting threads are awakened through this condition variable. After being awakened, the waiting thread rechecks the log output target and outputs the log to the new output target.

[0094] The present application scheme can realize dynamic control of log output targets, and it has the characteristics of flexibility, scalability, isolation, controllability, and real-time performance. Flexibility is reflected in the real-time change of output targets according to user needs. Scalability refers to the ability to flexibly add new output targets. Isolation means that each output target is independent and can be operated separately without affecting each other. Real-time performance means that the output target can be changed during system operation without restarting the application. The purpose and significance of realizing multiple output targets of logs include: meeting different needs at different stages, such as wanting to view logs on the console during the development stage, and wanting to write logs to files or send them to remote servers during the production stage; reliability, when an output target has a problem, the log can be saved through other output targets; easy to analyze, different output targets are suitable for different analysis methods, such as logs output to files are more suitable for offline analysis, and logs output to remote servers are convenient for real-time analysis and monitoring.
