It should be noted that, in the method for storing log information provided in the embodiment of the present invention, the execution main body may be a terminal device, or a Central Processing Unit (CPU) of the terminal device, or a control module in the terminal device for executing the method for storing log information. In the embodiment of the present invention, a method for executing log information storage by a terminal device is taken as an example, and the method for storing log information provided in the embodiment of the present invention is described.
The terminal device in the embodiment of the present invention may be a terminal device having an operating system. The operating system may be an Android (Android) operating system, an ios operating system, or other possible operating systems, and embodiments of the present invention are not limited in particular.
The following describes a software environment applied to the method for storing log information according to the embodiment of the present invention, by taking an android operating system as an example.
Fig. 1 is a schematic diagram of an architecture of a possible android operating system according to an embodiment of the present invention. In fig. 1, the architecture of the android operating system includes 4 layers, which are respectively: an application layer, an application framework layer, a system runtime layer, and a kernel layer (specifically, a Linux kernel layer).
The application program layer comprises various application programs (including system application programs and third-party application programs) in an android operating system.
The application framework layer is a framework of the application, and a developer can develop some applications based on the application framework layer under the condition of complying with the development principle of the framework of the application. For example, applications such as a system setup application, a system chat application, and a system camera application. And the third-party setting application, the third-party camera application, the third-party chatting application and other application programs.
The system runtime layer includes libraries (also called system libraries) and android operating system runtime environments. The library mainly provides various resources required by the android operating system. The android operating system running environment is used for providing a software environment for the android operating system.
The kernel layer is an operating system layer of an android operating system and belongs to the bottommost layer of an android operating system software layer. The kernel layer provides kernel system services and hardware-related drivers for the android operating system based on the Linux kernel.
Taking an android operating system as an example, in the embodiment of the present invention, a developer may develop a software program for implementing the method for storing log information provided in the embodiment of the present invention based on the system architecture of the android operating system shown in fig. 1, so that the method for storing log information may run based on the android operating system shown in fig. 1. Namely, the processor or the terminal device can implement the method for storing log information provided by the embodiment of the invention by running the software program in the android operating system.
The method for storing log information provided by the embodiment of the present invention is described in detail below with reference to the flowchart of the method for storing log information shown in fig. 2. Wherein, although a logical order of methods of storing log information provided by embodiments of the present invention is illustrated in a method flow diagram, in some cases, the steps illustrated or described may be performed in an order different than here. For example, the method of storing log information shown in fig. 2 may include S201, S202, and S203:
s201, the terminal device obtains first log information generated in the operation process of the terminal device.
It is understood that the terminal device may generate log information (such as the first log information) for recording the operation process of the terminal device during the operation process, wherein the log information may be referred to as log. In this way, the log information generated during the operation of the terminal device within a period of time may be information for reflecting the operation process of the terminal device within the period of time. For example, in the case where an abnormality occurs in a terminal device, the log information generated by the terminal device may be information for reflecting the abnormality, that is, information related to the abnormality. The first log information may include one or more log information.
Specifically, different types of log information can be generated in the operation process of the terminal device provided by the embodiment of the invention, for example, different types of log information can be generated in the operation process of a mobile phone adopting an Android operating system. The log information (e.g., the first log information) generated by the terminal device may be an Application Processor (AP) log or a Modem (Modem) log. Specifically, the AP log is used for analyzing and processing an application program exception on the terminal device, and the Modem log is used for analyzing and processing a communication protocol related function exception on the terminal device.
The AP log may be log information corresponding to an Application subsystem (APSS) of the terminal device, and the APSS is also referred to as an APSS module. The Modem log may be log information corresponding to a Modem application subsystem (MPSS), which is also referred to as an MPSS module.
For example, the application program exception of the terminal device may be that an application program (e.g., a system application program) in the terminal device cannot be started or is flashed back. For example, the "address book application" in the terminal device cannot be started.
For example, the communication protocol related function on the terminal device is abnormal, and an abnormality may occur to the call service executed by the terminal device, for example, the terminal device has no sound when executing the call service.
S202, the terminal device stores the first log information into a first storage space, wherein the first storage space is a storage space in a RAM in the terminal device.
Optionally, the first storage space provided in the embodiment of the present invention may be a part of a storage space in a RAM applied for by the terminal device, rather than a whole storage space in the RAM.
Specifically, the method for storing log information provided in the embodiment of the present invention may further include, before the step S201, step S200:
s200, the terminal equipment applies for a storage space with the capacity of preset capacity in the RAM from the terminal equipment, and the storage space with the capacity of preset capacity is used as a first storage space.
In the embodiment of the present invention, the capacity of the storage space in the RAM applied by the terminal device is usually smaller, that is, the preset capacity is smaller, for example, the preset capacity is 15 Megabytes (MB). I.e. the capacity of the first storage space is typically small, e.g. 15 MB.
Specifically, when the terminal device applies for a storage space in the RAM, a storage space with a preset capacity may be allocated from a free storage space of the current RAM as the first storage space.
Optionally, the first storage space in the terminal device may be a storage space with continuous physical addresses in the RAM, or a storage space with discontinuous physical addresses, which is not limited in this embodiment of the present invention.
Optionally, a function control (denoted as a first control) or an instruction input interface (a first interface) for triggering the terminal device to apply for a storage space in the RAM may be provided in the system setting or the application program of the terminal device. Specifically, after the terminal device receives an input of the first control from the user, or receives a specific code input in the first interface from the user, S200 may be executed. In addition, the terminal device may also automatically execute the above S200 when the terminal device is powered on.
Illustratively, the terminal device may be configured with a High-level Operating System (HLOS). The terminal device can apply for the first memory space in the RAM by its HLOS. Specifically, the input of the user to the first control or the input of the user to the first interface may be used to trigger the terminal device to call its HLOS to apply for the first storage space in the RAM.
It can be understood that after the terminal device applies for obtaining the first storage space, the terminal device starts to store the log information in the first storage space until the terminal device generates and obtains the first piece of log information. For example, the first log information provided by the embodiment of the present invention is the first log information stored after the terminal device applies for obtaining the first storage space.
In addition, the terminal device may sequentially store the generated log information in the first storage space in a queue form in order of the generation time of the log information from early to late. The log information with the earlier generation time of the terminal equipment can be stored in the front storage position in the first storage space; conversely, the log information generated later by the terminal device may be stored in a later storage location in the first storage space.
Specifically, when the terminal device generates the first log information, if the first storage space of the terminal device is full, the terminal device may delete some log information stored in the first storage space at the earliest generation time (that is, at the earliest storage location), and store the first log information in a later storage location in the first storage space. That is, the terminal device may delete one or more pieces of log information in the first storage space, so that there is enough capacity in the first storage space to store the first log information (i.e., the log information that is newly generated by the terminal device). The process of storing the log information into the first storage space by the terminal device may be recorded as a loop coverage storage process.
And S203, when the terminal equipment is abnormal, the terminal equipment stores the first log information into a second storage space, wherein the second storage space is a storage space in a ROM in the terminal equipment.
It is understood that, in the process of storing the first log information in the second storage space by the terminal device, the terminal device may store all the log information in the current first storage space in the second storage space. At this time, all log information in the first storage space includes the first log information, or the all log information is the first log information itself.
The ROM of the terminal device may be a Flash Memory (Flash Memory) or a Secure Digital Card (SD Card) in the terminal device.
It can be understood that, in the embodiment of the present invention, after S202 and before S203, the terminal device may determine that an abnormality occurs in the terminal device.
The terminal equipment can autonomously judge whether the terminal equipment is abnormal or not so as to determine that the terminal equipment is abnormal. Or, the user may determine whether the terminal device is abnormal or not according to experience, and indicate the terminal device that the terminal device is abnormal. Specifically, after the terminal device determines that the terminal device is abnormal, the above S203 may be executed.
Specifically, the terminal device provided in the embodiment of the present invention may include an abnormality identification module, where the abnormality identification module is configured to detect whether the mobile terminal is abnormal.
Optionally, a function control (denoted as a second control) or an instruction input interface (denoted as a second interface) for triggering the terminal device to store the log information in the first storage space into the second storage space may be provided in the system setting or the application program of the terminal device. Specifically, the terminal device may execute S203 after receiving an input of the second control from the user or receiving a specific code input in the second interface by the user.
It can be understood that the terminal device that may be provided in the embodiment of the present invention may include a user interface (DCI) for changing an operation mode of the Diag _ mdlog process. The second control may be a control corresponding to the DCI interface, or the second interface may be an interface of a client including the DCI interface.
In addition, in the embodiment of the present invention, the capacity of the second storage space may be greater than or equal to the capacity of the first storage space.
Optionally, in this embodiment of the present invention, the second storage space in the ROM of the terminal device may be preset by the terminal, or the terminal device applies for the ROM of the terminal device. The terminal device may use a storage space with a capacity greater than or equal to the preset capacity in the ROM as the second storage space.
Optionally, when the terminal device is abnormal, the terminal device may store the log information in the first storage space to the second storage area within a preset time. The terminal device can sequentially store the log information of the storage positions from front to back in the first storage space to the storage positions from front to back in the second storage space.
It can be understood that a duration for the terminal device to store all log information in the first storage area, the data amount of which is equal to the preset capacity, into the second storage space can be recorded as a first duration (e.g., 3 seconds).
Specifically, in order to ensure that the terminal device can store all log information in the first storage space into the second storage space, the preset duration may be greater than or equal to the first duration. For example, the preset time period is any one of 3 seconds to 6 seconds.
Illustratively, when the terminal device starts to store the log information in the first storage space into the second storage space, the log information in the first storage space may be recorded as a first set of log information, and the first set of log information includes the first log information.
It is understood that, when the terminal device starts to store the log information in the first storage space to the second storage space, the terminal device may also continue to generate log information (e.g., second log information) during the operation. At this time, the terminal device may store the second log information in the first storage space in a covering manner, and after the terminal device stores the first set of log information in the second storage space within a preset time period, the terminal device may store the second log information in the second storage space.
It is understood that the terminal device stores the log information into the second storage space continuously, that is, the log information stored into the second storage space may not be deleted by being overwritten.
It should be noted that the method for storing log information provided by the embodiment of the present invention is applied to a terminal device, and can obtain first log information generated in an operation process of the terminal device; storing the first log information into a first storage space, wherein the first storage space is a storage space in a RAM in the terminal equipment; in the case where an abnormality occurs in the terminal device, the first log information is stored in a second storage space, which is a storage space in a ROM in the terminal device. Based on the scheme, the terminal device can store the log information (such as the first log information) generated by the terminal in the storage space of the RAM in real time in the running process, so that the situation that the terminal device cannot acquire the log information generated under the condition that the terminal device is abnormal can be avoided. In addition, because only the log information generated when the terminal device is abnormal can be stored in the storage space of the ROM of the terminal device, and the log information generated by the terminal device does not need to be stored in real time for a long time, the storage space in the ROM of the terminal device can be occupied less, and the problem that the power consumption of the terminal device is large because the log information is stored in the ROM for a long time in real time is avoided. The method and the device can store the log information generated by the terminal equipment in real time under the condition that the power consumption of the terminal equipment is not increased and the storage space of a ROM of the terminal equipment is not excessively occupied, so that the log information related to the abnormity can be obtained under the condition that the terminal equipment is abnormal.
In a possible implementation manner, the method for storing log information provided in the embodiment of the present invention further includes S204 after S203. Illustratively, as shown in fig. 3, the method for storing log information according to an embodiment of the present invention further includes, after S203 shown in fig. 2, S204:
s204, the terminal equipment releases the first storage space.
It will be appreciated that the available free memory space of the RAM of the terminal device increases after the terminal device has released the first memory space. Therefore, the storage resource of the terminal equipment is saved, namely the storage resource in the process of storing the log information by the terminal equipment is saved.
In a possible implementation manner, the method for storing log information provided in the embodiment of the present invention further includes S205 before S201 provided in the above embodiment.
S205, the terminal device creates an obtaining process, and the obtaining process is used for obtaining log information generated in the running process of the terminal device.
Optionally, a system setting or an application of the terminal device may provide a function control (denoted as a third control) for capturing log information. Specifically, the terminal device may input the third control element to trigger the terminal device to create an obtaining process, so as to capture log information generated by the terminal device in real time.
It is to be understood that S200 in the above embodiment may be performed before S205 described above.
For example, the acquiring process that can be performed in the terminal device according to the embodiment of the present invention may be a diag _ mdlog process.
It should be noted that, in the embodiment of the present invention, the working modes adopted by the terminal device to run the acquisition process may include a loop mode and a stream mode. The terminal device works in a loop mode through the acquisition process, which refers to a process that the terminal device stores generated log information into a first storage space in the RAM in a loop mode. The terminal device works in a stream mode through the acquisition process, which refers to a process that the terminal device stores the log information in the first storage space into a second storage space in the ROM.
Illustratively, as shown in fig. 4, S201 shown in fig. 3 further includes S205, and S201 in the above embodiment may be implemented by S201 a:
s201a, the terminal device acquires the first log information through the acquisition process.
Illustratively, the terminal device may execute command line Sa: diag _ mdlog-t2-p2-f/sdcard/diag.cfg, to cause the terminal device to acquire log information, such as the first log information described above.
Wherein, the t parameter represents the running mode when the diag _ mdlog process is created, and 2 in t2 represents the loop mode; the p parameter represents log information of which modules are collected by the diag _ mdlog process, and 2 in p2 represents an MPSS module; the f parameter represents the log mask used by the diag _ mdlog process, which defines the information of the module that needs to be collected. The module that the terminal device defined by the log mask needs to acquire may be a sub-module in the MPSS module, for example, the MPSS module includes a module indicating a Global System for Mobile (GSM).
For example, the terminal device in the embodiment of the present invention may include an obtaining module, where the obtaining module may run the above-mentioned diag _ mdlog process.
It is understood that the terminal device executes the command line Sa, i.e., may acquire the first log information through the acquisition process. Accordingly, after the terminal device acquires the first log information, the first log information can be stored in the first storage space by the acquiring process in a loop mode. At this time, the terminal device executes the command line Sa, and S201 and S202 in the above embodiment may be executed corresponding to the terminal device.
Further, the terminal device may execute command line Sb: diag _ dci _ client-i < the _ input _ file >/contents: 4b, 12, c, 8, 0, 1, 0.
The diag _ DCI _ client is a DCI interface client, the client may call the DCI interface to change the operation mode of the diag _ mdlog, and the command line Sb may change the operation mode of the diag _ mdlog into the streaming mode.
It is understood that when the terminal device executes the command line Sb, the terminal device may store the log information in the first storage space into the second storage space, that is, the terminal device may execute S203.
Specifically, as shown in fig. 4, S202 in the above embodiment may be implemented by S202a, and S203 may be implemented by S203 a:
s202a, the terminal device stores the first log information in the first storage space in a round-robin manner through the acquisition process.
S203a, under the condition that the terminal device is abnormal, the terminal device stores the log information in the first storage space to the second storage space by adopting a stream mode through the acquisition process.
In addition, as shown in fig. 4, S204 in the above embodiment may be implemented by S204 a:
s204a, the terminal device terminates the acquiring process and releases the first storage space.
For example, in the embodiment of the present invention, the terminal device may execute command line Sc: diag _ mdlog-p 2-k-c.
The p parameter is already described in the command line Sa, and is not described herein again. The k parameter represents closing the diag _ mdlog process; the c parameter represents the log mask described by the purge command line Sa (e.g., log information included in the MPSS module indicating that the GSM module corresponds to).
It is understood that the terminal device may start executing the command lines Sa and Sb under automatic triggering or under user triggering. Subsequently, in the event of an abnormality of the terminal device, the terminal device triggers automatically, or under the trigger of the user, execution of the command line Sc may be started.
It should be noted that, in the method for storing log information provided in the embodiment of the present invention, the terminal device does not need to store the log information, and the terminal device may not store the log information in the RAM; also, in the case where no abnormality occurs in the terminal device, the terminal device may not store the log information in the ROM.
