Description

Technical Field

[0001] This disclosure relates to the field of data processing technology, and in particular to methods, apparatus, electronic devices, and storage media for copying folders. Background Technology

[0002] With the development of cloud storage technology, cloud space provides users with cloud storage services with ultra-large storage space. Therefore, when users copy folders in cloud space, it usually involves millions of full files, which makes the whole operation take a long time and has a high latency. During the folder copying process, in order for the copying task to proceed smoothly, the files in the target folder are usually locked, meaning that these files cannot be operated on. As a result, the files are occupied for a long time, making it impossible for users to use the files. Summary of the Invention

[0003] This disclosure provides a method, apparatus, electronic device, and storage medium for copying folders to solve at least one of the above-mentioned technical problems.

[0005] In response to a folder copy request, create a folder copy task;

[0006] Create a target folder corresponding to the source folder at the target location that matches the folder copy request, and create a pointer relationship on the target folder pointing to the source folder. The pointer relationship is used to direct the user's operation on the target folder to the source folder.

[0007] Execute the folder copy task to copy the files in the source folder to the target folder, and cancel the pointing relationship after the copy is completed.

[0008] According to another aspect of this disclosure, a folder copying apparatus is provided, the apparatus comprising:

[0009] The task creation module is used to create folder copy tasks in response to folder copy requests;

[0010] The pointer relationship creation module is used to create a target folder corresponding to the source folder at a target location that matches the folder copy request, and to create a pointer relationship on the target folder pointing to the source folder. The pointer relationship is used to direct the user's operation on the target folder to the source folder.

[0011] The task execution module is used to execute the folder copying task, copy the files in the source folder to the target folder, and cancel the pointing relationship after the copying is completed.

[0012] According to another aspect of this disclosure, an electronic device is provided, comprising:

[0013] At least one processor; and

[0014] A memory communicatively connected to the at least one processor; wherein,

[0015] The memory stores instructions that can be executed by the at least one processor to enable the at least one processor to perform the folder copying method described above.

[0030] The method for copying the vehicle security asset folder according to this disclosure can be executed by an electronic device such as a terminal device or a server. The terminal device can be an in-vehicle device, user equipment (UE), mobile device, user terminal, terminal, cellular phone, cordless phone, personal digital assistant (PDA), handheld device, computing device, in-vehicle device, wearable device, etc. The method can be implemented by a processor calling computer-readable program instructions stored in memory. Alternatively, the in-vehicle voice interaction method provided in this disclosure can be executed by a server.

[0031] It should be noted that the folder copying method provided in this disclosure can be executed on a storage server (e.g., in the cloud) or on a local storage device, and is not limited to either.

[0032] In the first disclosed embodiment, see Figure 1 , Figure 1 A flowchart illustrating a folder copying method according to a first embodiment of this disclosure is shown. The method includes:

[0033] S101. In response to the folder copy request, create a folder copy task.

[0034] The folder copy request must contain at least task information, which includes at least: the source folder (the folder to be copied), the target folder (the folder into which the files are copied), and may also include task identification (UserIdentification, UID), task type (e.g., folder copy type), etc.

[0035] Furthermore, to obtain information related to task execution, preset parameters can be added to the task information. These preset parameters include, for example, operation time (the time elapsed during task execution) and task status. A task identifier (TaskID) is then assigned to the folder copy task, and the operation time and task status are added to the task information. A relationship is established between the task identifier and the task information, and the task identifier, task information, and their relationship are recorded in a preset task database table. This allows for subsequent retrieval of the folder copy task's execution information from the task database table.

[0036] The task identifier for the folder copy task is a globally unique identifier. Throughout the copying process, the folder copy task has only one task identifier. By binding the task information with the task identifier and storing it in the task database table, the required task information can be retrieved through the task identifier.

[0037] S102. Create a target folder corresponding to the source folder at the target location that matches the folder copy request, and create a pointer relationship between the target folder and the source folder on the target folder.

[0038] This method describes the copying process of copying files from the source folder to the target folder. The target location in S102 is the location selected by the user to store the newly copied folder (target folder).

[0039] The pointing relationship is used to direct user operations on the target folder to the source folder.

[0040] Furthermore, in some examples, the pointing relationship is represented as a symbolic link. Specifically, creating a pointing relationship from the target folder to the source folder on the target folder in S102 includes:

[0041] Create a symbolic link on the target folder that points to the source folder.

[0042] A soft link is a symbolic link that contains path information to the object it points to (the source folder). Deleting a soft link does not affect the folder it points to.

[0043] In this way, at the beginning of the folder copying task, a target folder corresponding to the copied state is created at the target location, and the target folder is linked to the source folder. Thus, during the execution of the folder copying task, if the user wants to view the copied files in the target folder, in other words, if the user performs file operations on the target folder, the file operation can be directed to the source file, and the source file can call the target file corresponding to the file operation for the user to view.

[0044] S103. Execute the folder copy task, copy the files in the source folder to the target folder, and remove the pointer relationship after the copy is completed.

[0045] This approach creates a target folder that points to the source folder, allowing users to navigate to the source folder and view the files to be copied during the copying process. This ensures file availability and prevents the copying process from consuming files.

[0046] In the disclosed second embodiment, see Figure 2 , Figure 2 A flowchart illustrating a folder copying method according to a second embodiment of this disclosure is shown. The method includes:

[0047] S201. In response to the folder copy request, generate a folder copy task based on the task information contained in the folder copy request.

[0048] The task information includes at least the source folder and the target folder, and may also include information such as the task identifier and task type. The task identifier is the UID corresponding to the folder copy operation included in the folder copy request; the task type is, for example, "folder copy"; the source file is the folder to be copied; and the target folder is the folder into which the file will be copied in this task.

[0049] S202. Assign a task identifier to the folder copying task, add the operation time and task status to the task information, and establish the association between the task identifier and the task information.

[0050] The task status is one of the following: initial task status (i.e., the state when the folder copying task has just been generated and has not yet been executed), task in execution status, task execution failed status, or task execution completed status (all tasks have been completed).

[0051] S203. Record the task identifier, task information, and their relationship into the preset task database table.

[0052] To obtain information about task execution, preset parameters can be added to the task information. These preset parameters may include, for example, operation time (the time elapsed during task execution) and task status. Then, a task identifier is assigned to the folder copy task, and the operation time and task status are added to the task information. The task identifier and task information are then linked; in other words, a relationship is established between the task identifier and task information. The task identifier, task information, and the relationship between them are recorded in a preset task database table, allowing for subsequent retrieval of folder copy task execution information from the task database table.

[0053] The task identifier for the folder copy task is a globally unique identifier. Throughout the copying process, the folder copy task has only one task identifier. By binding the task information with the task identifier and storing it in the task database table, the required task information can be retrieved through the task identifier.

[0054] S201-S203 are one implementation of S101. S101 can also be implemented in other ways, which are not limited here.

[0055] S204. Create a target folder corresponding to the source folder at the target location that matches the folder copy request, and create a pointer relationship from the target folder to the source folder on the target folder.

[0056] The pointing relationship is used to direct user operations on the target folder to the source folder.

[0057] Furthermore, in some examples, the pointing relationship is represented as a symbolic link. Specifically, creating a pointing relationship from the target folder to the source folder on the target folder in S102 includes:

[0058] Create a symbolic link on the target folder that points to the source folder.

[0059] A soft link is a symbolic link that contains path information to the object it points to (the source folder). Deleting a soft link does not affect the folder it points to.

[0060] In this way, at the beginning of the folder copying task, a target folder corresponding to the copied state is created at the target location, and the target folder is linked to the source folder. Thus, during the execution of the folder copying task, if the user wants to view the copied files in the target folder, in other words, if the user performs file operations on the target folder, the file operation can be directed to the source file, and the source file can call the target file corresponding to the file operation for the user to view.

[0061] S205. Set the target folder's folder status to "copy incomplete".

[0062] The folder status can be either "copy incomplete" or "copy complete". After creating the folder copy task, the target folder's status is initially set to "copy incomplete". During task execution, the task status is periodically checked according to a preset cycle. When a "task completion" status (all tasks are complete) is detected, the target folder's status is changed to "copy complete".

[0063] The duration of the preset period can be set arbitrarily according to the specific implementation method, for example, it can be set to 10ms.

[0064] In some examples, following S205, the folder copying method provided in this disclosure also includes:

[0065] Step 1: In response to file viewing operations on the target folder and any item in any file within the target folder, determine the folder status of the target folder.

[0066] Step 2: If the folder status is confirmed to be incomplete copying, point the file viewing operation to the source folder according to the pointing relationship, and identify the target file in the source folder that corresponds to the file viewing operation.

[0067] Step 3: Perform file viewing operations on the target file.

[0068] In an embodiment where the folder status of the target folder is set, if a user sends a file viewing operation targeting the target folder or any file within the target folder, i.e., the copying task has been completed based on the folder status or whether the current folder copying task has been completed, if the copying task has not been completed (i.e., the folder status is "copying incomplete"), the system jumps to the source folder via a pointer relationship to determine the target file in the source folder corresponding to the file viewing operation, and then performs the file viewing operation on the target file. If the copying task has been completed (i.e., the folder status is "copying complete"), the system directly views the file corresponding to the file viewing operation in the target folder. In this way, the completion status of the folder copying task can be determined directly through the folder status without querying the task database table, thereby reducing the amount of data processing.

[0069] It should be noted that steps one through three can be executed at any time after S204, and there is no restriction on the execution order.

[0070] S206. Divide the multiple sub-file objects contained in the source folder into multiple object groups.

[0071] S207. Generate multiple asynchronous folder copying subtasks for multiple object groups respectively.

[0072] When the source folder contains a large number of subfile objects (which can be at least one of subfolders or files), such as millions of subfile objects, multiple subfile objects can be divided into multiple object groups, and an asynchronous folder copying subtask can be generated for each object group.

[0073] S208. Execute multiple asynchronous folder copying subtasks sequentially, and update the task status of the folder copying task in the task database table according to the execution progress.

[0074] An execution queue is generated based on multiple asynchronous folder copying subtasks. The multiple asynchronous folder copying subtasks are executed sequentially according to the order of the execution queue and in an asynchronous manner. By copying in batches, task blocking can be reduced and the reliability of task execution can be improved.

[0075] Furthermore, during the execution of multiple asynchronous folder copying subtasks, the task status of the folder copying task in the task database table is updated according to the execution progress. Specifically, S208 includes any of the following execution methods:

[0076] Method 1: Execute multiple asynchronous folder copying subtasks sequentially and change the task status to "task in progress".

[0077] Method 2: If multiple asynchronous folder copy subtasks have completed execution, change the task status to "all tasks completed".

[0078] Method 3: If any asynchronous folder copy subtask fails to execute, change the task status to "Task Execution Failed".

[0079] If any asynchronous folder copying subtask fails during execution, the task status in the task database table will be changed to "task execution failed" before the task exits. Furthermore, the task database table will record the target asynchronous folder copying subtask corresponding to the task interruption point in the task information based on the execution queue. This allows the failed target asynchronous folder copying subtask to be restarted using the task execution failure status and the task interruption point. In this way, the success rate of task execution is improved, and data consistency is ensured after file copying failures.

[0080] S209. After detecting that the task status of the folder copying task is "all tasks completed", cancel the pointing relationship.

[0081] The task database table is called periodically to check the task status of the current folder copying task. Once the task status is confirmed as "all tasks completed," the copying is deemed complete, and the pointer relationship to the target folder can be cancelled. This allows subsequent operations on the target folder to be performed normally. This step ensures that the pointer relationship becomes invalid after the task is completed. In embodiments where the pointer relationship is a symbolic link, cancelling the pointer relationship specifically involves deleting the symbolic link.

[0082] The duration of the preset period can be set arbitrarily according to the specific implementation method, for example, it can be set to 20ms.

[0083] Specifically, S206-S209 is one implementation of S102. S102 also has other implementations, which are not limited here. Furthermore, when the source folder contains a large number of sub-file objects, it can be executed according to S206-S209. When the source folder contains a small number of sub-file objects, S206-S209 can be omitted, and all sub-file objects to be copied can be packaged into a single task for execution.

[0084] S210. Delete the task identifier, task information, and association relationships of the folder copy task from the task database table.

[0085] Once the task execution is confirmed to be complete—in other words, once the task status of the folder copy task is detected as "all tasks completed"—the task identifier, task information, and associations of the folder copy task are deleted from the task database table. This reduces redundant information in the task database table and prevents completed folder copy tasks from being accidentally triggered.

[0086] S211. Set the folder status of the target folder to copy complete.

[0087] Once the task execution is confirmed to be complete, in other words, after the task status of the folder copying task is detected to be "all tasks completed", the folder status of the target folder is set to "copy completed". Thus, when the task execution is complete (i.e. the folder status is "copy completed"), operations on the target folder are directly performed on the target folder, and changes can be made to both the target folder and the source folder.

[0088] It should be noted that the execution order of S210 and S211 can be interchanged, and no restriction is made here.

[0089] Based on the above, this disclosure also establishes an exception handling mechanism for task abnormalities during the execution of a folder copying task. Specifically, based on the above-mentioned method three, S208, it also includes:

[0090] Step 1: Check the task status according to the preset cycle.

[0091] The duration of the preset period can be set arbitrarily according to the specific implementation method, for example, 15ms. The purpose of step one is to set a periodic anomaly detection cycle to check the task status and detect task anomalies in a timely manner.

[0092] Step 2: Based on the task status detection, perform the corresponding task processing operations for the folder copying task.

[0093] Multiple sets of matching relationships between detection conditions and task processing operations can be preset. The detection conditions include one of the following: the task status is detected as a task execution failure state, or the operation time of any asynchronous folder copying subtask exceeds a preset threshold. The task processing operations include one of the following: the task interruption point is determined and the target asynchronous folder copying subtask is restarted, or the asynchronous folder copying subtask whose operation time exceeds the preset threshold is restarted.

[0094] Specifically, in some examples, step two includes the following sub-steps:

[0095] Sub-step A: If the task status is detected as a task execution failure, determine the task interruption point.

[0096] Sub-step 2A: Determine the target asynchronous folder corresponding to the task interruption point, copy the sub-task, and restart the target asynchronous folder copy sub-task.

[0097] According to method three in S208, if any asynchronous folder copying subtask fails during execution, the task status of the folder copying task in the task database table will be changed to a task execution failure status before the task exits. Furthermore, the task database table will record the target asynchronous folder copying subtask corresponding to the task interruption point in the task information of the folder copying task according to the execution queue. Thus, in sub-steps A and B, if a task status of task execution failure is detected, the task interruption point can be determined through the task database table, and the failed folder copying subtask can be identified as the target asynchronous folder copying subtask through the task endpoint. Then, the failed target asynchronous folder copying subtask will be restarted.

[0098] Alternatively, step two may include the following sub-steps:

[0099] Sub-step B: If the operation time of any asynchronous folder copying subtask exceeds a preset threshold, interrupt the asynchronous folder copying subtask whose operation time exceeds the preset threshold.

[0100] Sub-step 2B: Restart the asynchronous folder copying subtask whose operation time exceeds the preset threshold.

[0101] The preset threshold is a reference time for determining when a task is stuck. It can be set according to specific implementation requirements, for example, it can be set to 1 minute.

[0102] In some cases, asynchronous folder copying subtasks may exit abnormally without changing the task status to "task execution failed." In such cases, the task status remains "task execution in progress," causing the exception to go undetected. Therefore, a preset threshold for the exception period can be set. By checking the operation time of the current task in the task data table, if the operation time exceeds the preset threshold, it can be determined that the task has encountered an exception. This triggers an interruption operation on the current asynchronous folder copying subtask, changing the task status to "task execution failed," thereby triggering a restart mechanism to restart asynchronous folder copying subtasks whose operation time exceeds the preset threshold.

[0103] By using the above methods, task anomalies can be detected and intervened in a timely manner, ensuring the success rate of replication tasks and data consistency.

[0104] It should be noted that steps one and two can be executed at any time during the entire process after S207 and before S209 (specifically, they can be executed periodically according to a preset cycle), and there are no restrictions here.

[0105] Based on the above, this disclosure also establishes a mechanism to protect the file integrity of the source and target folders during the execution of a folder copying task. Specifically, see [link to documentation]. Figure 3 , Figure 3 This flowchart illustrates the steps for protecting copied files in the folder copying method provided in this disclosure. Based on the folder state setting embodiment in S205 above, the folder copying method provided in this disclosure further includes:

[0106] S201' In response to a file change operation on any of the following: source folder, any file in the source folder, target folder, or any file in the target folder, determine the folder status of the target folder.

[0107] S202' Determine the execution method for file change operations based on the folder status.

[0108] To protect the integrity of the source folder and its files, as well as the target folder and its files, the status of the target folder can be used to determine whether the copying task has been completed. If the copying task is not completed, operations that would damage the integrity of the source folder and its files (i.e., file modification operations) will not be performed on the source folder and its files, or the target folder and its files. Only viewing operations are allowed. This method protects the integrity of the files, prevents files from being accidentally deleted before the copying task is completed, and improves the reliability of the folder copying method provided in this embodiment.

[0109] Specifically, S202' includes the following situations:

[0110] (1) If the folder status is confirmed to be copied, perform the file change operation.

[0111] If the folder status is detected as "copy complete", the copy task can be considered complete. In this case, the folder is no longer locked, and file modification operations can be performed normally.

[0112] (2) If the folder status is determined to be in an incomplete copying state, determine the execution method of the file change operation according to any of the following.

[0113] Method 1: Disable file modification operations.

[0114] Method 2: Generate an asynchronous file change task based on the file change operation; execute the asynchronous file change task when the folder status is detected as "copy complete".

[0115] If the folder status is detected as "not copied incomplete," meaning the copying task has not been completed, the integrity of the files needs to be protected. This can be achieved by directly prohibiting the operation, or by generating an asynchronous file change task. After generating the asynchronous file change task, its related information can be stored in the aforementioned task database table and queued. When the folder status is detected as "copy completed," the asynchronous file change task is executed according to the queue order, and its related information is deleted from the task database table after execution.

[0116] File modification operations include at least one of the following: deletion operation, transfer operation, etc.

[0117] It should be noted that S201' and S202' can be executed at any time during the file copying process, and there are no restrictions here.

[0118] In the third disclosed embodiment, based on and Figure 1 The same principle, Figure 4 This invention discloses a folder copying apparatus 40 according to a third embodiment of the present invention, the apparatus comprising:

[0119] Task creation module 401 is used to create a folder copy task in response to a folder copy request.

[0120] The pointer relationship creation module 402 is used to create a target folder corresponding to the source folder at the target location that matches the folder copy request, and to create a pointer relationship on the target folder pointing to the source folder. The pointer relationship is used to direct the user's operation on the target folder to the source folder.

[0121] Task execution module 403 is used to perform folder copying tasks, copying files from the source folder to the target folder, and canceling the pointer relationship after the copying is completed.

[0122] The pointer relationship is represented as a symbolic link; the pointer relationship creation module is specifically used for:

[0143] If a task is detected to be in a failed execution state, determine the task interruption point.

[0144] Identify the target asynchronous folder copy subtask corresponding to the task interruption point, and restart the target asynchronous folder copy subtask;

[0145] or,

[0146] If the operation time of any asynchronous folder copying subtask exceeds a preset threshold, the asynchronous folder copying subtask whose operation time exceeds the preset threshold will be interrupted.

[0147] Restart asynchronous folder copying subtasks whose operation time exceeds a preset threshold.

[0152] In some examples, the device also includes:

[0153] The folder status determination module is used to determine the folder status of the target folder in response to any file change operation on the source folder, any file in the source folder, the target folder, or any file in the target folder.

[0154] The execution method determination module is used to determine the execution method for file change operations based on the folder status.

[0155] In some examples, the execution method determination module is used for:

[0156] Once the folder status is confirmed to be "copy complete", perform the file modification operation;

[0157] Alternatively, if the folder status is determined to be incomplete copying, determine the execution method for the file change operation according to any of the following:

[0158] Do not perform file modification operations;

[0159] or,

[0160] Generate asynchronous file change tasks based on file change operations;
