Description

Technical Field

[0001] This invention relates to the field of information technology, and in particular to a file dumping method, apparatus, electronic device, and storage medium. Background Technology

[0002] With the continuous development of embedded platforms, both manufacturers and users are placing higher demands on the system stability of devices. When the operating system crashes or experiences abnormal states, the system needs to save a memory dump file, which is used for subsequent analysis of the operating system. In the event of an abnormal state, the system can use a dump component to dump the complete contents of the dump file to flash memory or hard disk, and then restart the operating system after the dump is complete.

[0003] Current dump file dumping methods typically store dump files in a fixed system partition. Because the system partition's size is inflexible and dump files in dumping scenarios often cannot be dynamically compressed, the system partition may be unable to handle excessive storage requirements when the dump file becomes too large. Furthermore, adjusting a fixed system partition can only be done after a system-wide update, and adjusting partitions through a system update can have complex impacts on internal storage.

[0035] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are merely one embodiment of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0036] The term "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of this application. In the description of the embodiments of this application, it should be understood that the terms "upper," "lower," "left," "right," "top," "bottom," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device / system or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature. Moreover, the terms "first," "second," etc., are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in a sequence other than that illustrated or described herein. Furthermore, the terms “comprising” and “having” / “being” and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system / apparatus, product or device that includes a series of steps or units / modules is not necessarily limited to those steps or units / modules that are explicitly listed, but may include other steps or units / modules that are not explicitly listed or that are inherent to such process, method, product or device.

[0037] The following describes a specific embodiment of a file dumping method provided in this application. Please refer to [link / reference]. Figure 1 , Figure 1 This is a schematic diagram illustrating an application scenario of a file dumping method provided in an embodiment of this application. For example... Figure 1 As shown, it includes server 101 and terminal 102. Optionally, server 101 and terminal 102 can be connected via a wireless link or a wired link, which is not limited in this disclosure.

[0038] Specifically, server 101 can be a standalone physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server providing basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDN (Content Delivery Network), and big data and artificial intelligence platforms. Optionally, the operating system running on server 101 may include, but is not limited to, iOS, Linux, Windows, Unix, Android, etc.

[0039] Specifically, terminal 102 may include, but is not limited to, electronic devices such as smartphones, desktop computers, tablets, laptops, smart speakers, digital assistants, augmented reality (AR) / virtual reality (VR) devices, and smart wearable devices. Optionally, the operating system running on the electronic device may include, but is not limited to, Android, iOS, Linux, and Windows.

[0040] In an optional embodiment, terminal 102 can run a bootloader when the operating system malfunctions. In the event of an abnormality such as a system crash, the operating system can perform a software reset, and the bootloader can dump the data from memory to flash memory. After the dump is complete, the operating system can restart normally. The dumped data can be used for subsequent analysis of the cause of the system abnormality. Optionally, the dumped data can be uploaded to server 101, where server 101 can uniformly analyze all dumped data under the current system version and determine a system upgrade plan based on the analysis. Since the size of the dump file used for dumping may need to be changed, and the memory space of terminal 102 is limited, terminal 102 needs to flexibly configure the space of the dump file. Optionally, terminal 102 can receive a dump file update request corresponding to the target test task and delete the original dump file in the first original dump space. The dump file update request includes the target file size of the target dump file. If the target file size meets a first preset condition, the target dump file is created in the first original dump space. Or, if the target file size meets a second preset condition, the first target dump space is determined from the system storage space based on preset storage conditions. The target dump file is created in the first target dump space. The target file position and target file size of the target dump file are written to the shared storage space by the operating system. The shared storage space can be read by the dump component. In an optional implementation, the dump file update request can be sent by server 101.

[0041] In addition, it should be noted that, Figure 1 The example shown is merely one application environment of the file dumping method provided in this disclosure. In practical applications, other application environments may also be included, but this embodiment does not limit this.

[0042] The following describes an exemplary process of a file dumping method provided in this application. Optionally, the entity executing a file dumping method can be a terminal or a file dumping system. Figure 2This is a first flowchart illustrating a file dumping method provided in an embodiment of this application. This specification provides the method or process steps shown in the embodiments or flowcharts, but based on conventional or non-inventive labor, more or fewer steps may be included. The order of steps listed in the embodiments is merely one of many execution orders and does not represent the only execution order. In actual execution, the method or process can be executed in the order shown in the embodiments or drawings, or in parallel (e.g., in a parallel processor or multi-threaded processing environment). Specifically, as shown... Figure 2 As shown, the method includes:

[0043] S201: Received a dump file update request corresponding to the target test task, and deleted the original dump file in the first original dump space.

[0044] Optionally, the dump file update request may include the target file size of the target dump file.

[0045] In one optional implementation, the terminal can be in the test scenario corresponding to the target test task. During the test phase, the terminal can receive a dump file update request and update the existing dump file according to the dump file update request so that the updated dump file matches the test requirements. The dump file can be exported by the terminal from the dumped location for analysis of the cause of the operating system anomaly.

[0046] In another alternative implementation, the terminal can be in a daily use scenario, and the target test task can correspond to the operating system version. The vendor server can send a dump file update request corresponding to the target test task to the terminal, so that the terminal's dump file is updated according to the vendor server's test requirements, thereby making the dump files subsequently collected by the vendor meet the analysis requirements. Subsequently, the vendor can update the terminal system based on the analysis results.

[0047] Optionally, the original dump file to be deleted can be a dump file used for dumping in system memory before a dump file update request is received. This original dump file can be a dump file created when the operating system first boots, or it can be a dump file that has been updated once or multiple times.

[0048] S202: If the target file size meets the first preset condition, create the target dump file in the first original dump space.

[0049] In one optional implementation, the first preset condition may be: the target file size is less than or equal to the original file size of the original dump file. Step S202 may include: if the target file size is less than or equal to the original file size of the original dump file, creating the target dump file in the first original dump space.

[0050] S203: If the target file size meets the second preset condition, determine the first target dump space from the system storage space based on the preset storage conditions.

[0051] In one optional implementation, the second preset condition may be: the target file size is greater than the original file size. Step S203 may include: if the target file size is greater than the original file size, determining a first target dump space from the system storage space based on preset storage conditions.

[0052] Since the operating systems of embedded platforms on terminals generally support various file systems, a dedicated partition for dumping files is not required; instead, the files can be stored in a writable data storage space that meets the requirements. For example, the / data partition on a mobile phone. In an optional implementation, if there is not enough contiguous space in the system memory, the system memory space can be released through disk cleanup; where system memory can refer to the operating system's running memory. Step S203 may include: if the target file size is larger than the original file size, determining a first remaining contiguous space from the system storage space; if the size of the first remaining contiguous space is greater than or equal to the target file size, determining the first remaining contiguous space as the first target dump space; or; if the size of the first remaining contiguous space is smaller than the target file size, cleaning up the system storage space to obtain an updated system space; the size of the updated system space is greater than or equal to the target file size; determining the first target dump space from the updated system space. Optionally, determining the first target storage space from the updated system space may include: determining a second remaining contiguous space from the updated system space; the size of the second remaining contiguous space is greater than or equal to the target file size; determining the second remaining contiguous space as the first target dump space.

[0053] Optionally, if disk cleanup fails to free up sufficient space in system memory, the first target dump space can be determined from flash memory. The first remaining contiguous space can be determined from flash memory; if the size of the first remaining contiguous space is greater than or equal to the target file size, this first remaining contiguous space is designated as the first target dump space.

[0054] S204: Create a target dump file in the first target dump space.

[0055] Optionally, a target dump file can be created in the first target dump space according to the target file size. The data blocks stored in the target dump file in the first target dump space can be contiguous.

[0056] In one alternative implementation, Figure 2Steps S202-S204 illustrated can also be replaced by the following steps: creating a target dump file in the first original dump space; if creation is successful, proceed to step S205; if creation fails, determine the first target dump space from the system storage space based on preset storage conditions; create a target dump file in the first target dump space. The specific content of creating the target dump file in the first original dump space, determining the first target dump space from the system storage space based on preset storage conditions, and creating the target dump file in the first target dump space in this embodiment can be referred to the above description, and will not be repeated here.

[0057] S205: The target file location and target file size of the target dump file are written to the shared storage space by the operating system.

[0058] Optionally, the shared storage space can be read by the dump component. The dump component may include a bootloader with read permissions for the shared storage space, and the operating system with write and read permissions for the shared storage space; the shared storage space can be in flash memory. After reading the target file location and size in the shared storage space, the dump component can perform a dump operation on the target file based on the read information.

[0059] Optionally, the operating system can write the target file location and target file size of the target dump file to the shared storage space, and replace the original file location and original file size stored in the shared storage space respectively.

[0060] Optionally, the target file location can be written to the first field of the shared storage space as a logical block address; the target file size can be written to the second field of the shared storage space. The first and second fields can be two UINT type fields, shm_dump_lba and shm_dump_size, set on the shared storage space.

[0061] Figure 3 This is a schematic diagram of the second process of a file dumping method provided in an embodiment of this application. The following is based on... Figure 3 This application further illustrates an exemplary flow of a file dumping method that includes steps following step S205. For example... Figure 3 As illustrated, step S205 may further include:

[0062] S301: If the operating system is detected to be in an abnormal state, the target file location and target file size are read from the shared storage space through the dump component.

[0063] Optionally, if an abnormal operating system is detected, or a dump request is detected, the target file location and target file size can be read from the shared storage space through the dump component.

[0064] S302: Read the target dump file based on the target file location and target file size using the dump component.

[0065] Optionally, the target dump file can be read by the dump component based on the target file location and target file size read by the dump component in step S301.

[0066] S303: Use the dump component to save the target dump file to the second target dump space.

[0067] Optionally, the second target dump file can be space in flash memory.

[0068] Optionally, after step 303, the method may further include: restarting the operating system; upon receiving a dump file export request, reading the target dump file of the second target dump space through the operating system.

[0069] Figure 4 This is a schematic diagram of the third process of a file dumping method provided in an embodiment of this application. The following is based on... Figure 4 This paper further illustrates an exemplary flow of a file dumping method according to an embodiment of the present application, which includes steps prior to step S201. For example... Figure 4 As illustrated, step S201 may also include:

[0070] S401: If a dump file creation request is received, determine the first original dump space from the system storage space based on the original file size.

[0071] Optionally, the dump file creation request may include the original file size of the original dump file.

[0072] In one optional implementation, a first remaining contiguous space can be determined from the system storage space; if the size of the first remaining contiguous space is greater than or equal to the original file size, the first remaining contiguous space is determined as the first original dump space; or; if the size of the first remaining contiguous space is less than the original file size, the system storage space is cleaned up to obtain updated system space; the size of the updated system space is greater than or equal to the original file size; the first original dump space is determined from the updated system space. Optionally, determining the first original storage space from the updated system space may include: determining a second remaining contiguous space from the updated system space; the size of the second remaining contiguous space is greater than or equal to the original file size; the second remaining contiguous space is determined as the first original dump space.

[0073] In an alternative implementation, step S401 can be executed when the terminal's operating system is first started.

[0074] S402: Create an original dump file in the first original dump space.

[0075] Optionally, an original dump file can be created in the first original dump space according to the original file size. The data blocks stored in the first original dump space can be contiguous.

[0076] Optionally, after step S402, the method may further include: writing the original file size and original file location of the original dump file into the shared storage space.

[0077] The file dumping method provided in this application allows for flexible adjustment of the dump space. When the dump file size is reduced, the dump space can be reduced to save storage space as much as possible while still meeting functional requirements. When the dump file size is increased, a larger dump space can be determined, satisfying the excessive dump file memory requirements without requiring a system-wide update or compression. Furthermore, the file dumping method provided in this application can update the dump file in a timely manner according to the needs of different testing scenarios, ensuring the collection of appropriate analytical data during test analysis and improving the efficiency of fault analysis.

[0080] The creation module 502 is used to create a target dump file in the first original dump space if the target file size meets the first preset condition; or; if the target file size meets the second preset condition, determine the first target dump space from the system storage space based on the preset storage conditions; and create the target dump file in the first target dump space.

[0081] The write module 503 is used to write the target file location and target file size of the target dump file to the shared storage space via the operating system; the shared storage space is used for reading by the dump component.

[0082] Optionally, the device also includes a dump module, which, after writing the target file location and target file size of the target dump file to the shared storage space through the operating system: if an abnormal state of the operating system is detected, reads the target file location and target file size from the shared storage space through the dump component; reads the target dump file based on the target file location and target file size through the dump component; and stores the target dump file to the second target dump space.

[0086] Optionally, the creation module 502 is also used to: determine a second remaining contiguous space from the updated system space; the size of the second remaining contiguous space is greater than or equal to the size of the target file; and determine the second remaining contiguous space as the first target dump space.

[0087] Optionally, the write module 503 is used to: write the target file location, in the form of a logical block address, into the first field of the shared storage space; and write the target file size into the second field of the shared storage space.
