Note that, the method for copying the folder provided in the present disclosure may be executed in a storage server (e.g., cloud), or may be executed in a local storage unit, which is not limited herein.

In disclosing a first embodiment, referring to fig. 1, fig. 1 shows a flowchart of a folder copying method provided in the first embodiment of the present disclosure. The method comprises the following steps:

s101, responding to a folder copying request, and creating a folder copying task.

The folder replication request at least comprises task information, and the task information in the folder replication request at least comprises: the source folder, i.e. the folder to be copied, the target folder (targetfolder), i.e. the target folder into which the file is copied, may also include information such as a task identity (UserIdentification, UID), a task type (e.g. folder copy type), etc.

In addition, in order to obtain the information related to the task execution, a preset parameter item may be added to the task information, where the preset parameter item includes, for example: operation time (time elapsed to execute a task) and task status. And then, task identification (task ID) is distributed to the folder replication task, operation time and task state are added in task information, an association relation between the task identification and the task information is established, and the task identification, the task information and the association relation between the task identification and the task information are recorded into a preset task database table so as to facilitate subsequent inquiry of execution related information of the folder replication task from the task database table.

The task identification of the folder replication task is globally unique identification, and in the whole replication process, the folder replication task only has one task identification, and the task information and the task identification are bound and stored in a task database table, so that the required task information can be called through the task identification.

S102, creating a target folder corresponding to the source folder at a target position matched with the folder replication request, and creating a pointing relation pointed to the source folder by the target folder on the target folder.

The present method describes a copying process of copying a file in a source folder to a target folder, and the target location in S102 is a location selected by the user as a location where a newly copied folder (target folder) is stored.

Wherein the pointing relationship is used to point a user's operation with respect to the target folder to the source folder.

Further, in some examples, the pointing relationship is represented as a soft link. Creating a pointing relationship on the target folder, pointed to by the target folder as the source folder in S102, specifically includes:

a soft link is created on the target folder from the target folder to the source folder.

Wherein the soft link is a symbol link (symbol link), the soft link contains path information to the pointed object (source folder), and deleting the soft link does not affect the pointed folder.

In this way, when the folder replication task is initiated, a target folder corresponding to the replication completion state is created at a target position, and the target folder is linked into the source folder, so that in the process of executing the folder replication task, if a user wants to view a file in replication in the target folder, in other words, the user performs a file operation on the target folder, the user can point the file operation to the source file, call the target file corresponding to the file operation through the source file, and provide the file operation for the user to view.

S103, executing a folder copying task, copying files in the source folder into the target folder, and canceling the pointing relation after copying is completed.

By creating the target folder with the pointing relation pointing to the source folder in this way, the user can jump to the source folder to check the files to be copied through the target folder in the process of executing the folder copying task, thereby ensuring the usability of the files and avoiding the occupation of the files in the copying process.

In disclosing the second embodiment, referring to fig. 2, fig. 2 shows a flowchart of a folder copying method provided by the second embodiment of the present disclosure. The method comprises the following steps:

S201, responding to the folder copying request, and generating a folder copying task according to task information contained in the folder copying request.

Wherein, the task information at least comprises: the source folder and the target folder can also comprise information such as task identity marks, task types and the like. The task identity is a UID corresponding to a folder copying operation included in the folder copying request, the task type is, for example, a folder copying type, the source file is a folder to be copied, and the target folder is a target folder in which the file is copied in the task.

S202, task identification is allocated to the folder copying task, operation time and task state are added to the task information, and an association relation between the task identification and the task information is established.

The task state is one of a task initial state (i.e., a state when the file folder is just generated to copy the task and is not yet executed), a task in-process state, a task execution failure state, and a task execution completion state (all task execution completion states).

S203, recording the task identification, the task information and the association relation of the task identification and the task information into a preset task database table.

In order to obtain the information related to the task execution, a preset parameter item may be added to the task information, where the preset parameter item includes, for example: operation time (time elapsed to execute a task) and task status. And then, task identification is distributed to the folder replication task, operation time and task state are added in the task information, and the task identification and the task information are bound, in other words, an association relation between the task identification and the task information is established, and the task identification, the task information and the association relation between the task identification and the task information are recorded in a preset task database table so as to facilitate subsequent inquiry of the execution related information of the folder replication task from the task database table.

S201-S203 are one implementation of S101, specifically, S101 has other implementations, which are not limited herein.

S204, creating a target folder corresponding to the source folder at a target position matched with the folder replication request, and creating a pointing relation pointed to the source folder by the target folder on the target folder.

S205, the folder state of the target folder is set to the copy incomplete state.

Wherein the folder state is one of a copy incomplete state and a copy complete state. After creating the folder replication task, the folder state of the target folder is expressed as a replication incomplete state, the task state of the folder replication task is regularly detected according to a preset period in the task execution process, and the folder state of the target folder is modified into a replication complete state when the task execution complete state (all task execution complete states) is detected.

The duration of the preset period may be arbitrarily set according to a specific implementation manner, for example, set to 10ms.

In some examples, after S205, the method for copying folders provided by the present disclosure further includes:

step one: in response to a file view operation for any of the target folder, any of the files in the target folder, a folder state of the target folder is determined.

Step two: and under the condition that the folder state is determined to be in a copying incomplete state, pointing the file viewing operation to the source folder according to the pointing relation, and determining a target file corresponding to the file viewing operation in the source folder.

Step three: and executing file viewing operation on the target file.

In the embodiment of setting the folder state of the target folder, if a file checking operation that an execution object is the target folder or any file in the target folder and is sent by a user is received, namely, if the copying task of the current folder is completed through the folder state or not, and if the copying task is not completed (namely, the folder state is a copying incompletion state), the folder is jumped through the pointing relation, the target file matched in the folder by the file checking operation is determined, and the file checking operation is executed for the target file; and under the condition that the execution of the copying task is completed (namely, the folder state is the copying completion state), directly checking the file corresponding to the file checking operation through the target folder. In this way, the completion condition of the folder copying task can be determined directly through the folder state without calling a task database table to query the task state, so that the data processing amount can be reduced.

It should be noted that, the first step-the third step may be performed at any period after S204, and the execution order is not limited herein.

S206, dividing the plurality of sub-file objects contained in the source folder into a plurality of object groups.

S207, generating a plurality of asynchronous folder replication subtasks for a plurality of object groups respectively.

In the case where the number of subfile objects (which may be at least one of subfolders, files) included in the source folder is large (e.g., millions), the multiple subfile objects may be divided into multiple object groups, with one asynchronous folder replication sub-task being generated for each object group.

S208, sequentially executing a plurality of asynchronous folder replication subtasks, and updating task states of the folder replication tasks in the task database table according to the execution progress.

And generating an execution queue according to the plurality of asynchronous folder replication sub-tasks, sequentially executing the plurality of asynchronous folder replication sub-tasks according to the order of the execution queue and the mode of asynchronous tasks, and reducing the occurrence of task blocking and improving the reliability of task execution by a mode of batch replication.

And, in the process of executing the plurality of asynchronous folder replication subtasks, updating the task state of the folder replication tasks in the task database table according to the execution progress, specifically, S208 includes executing in any one of the following manners:

Mode one: and sequentially executing a plurality of asynchronous folder replication subtasks, and changing the task state into a state in task execution.

Mode two: in the case that the execution of the plurality of asynchronous folder replication sub-tasks is completed, the task state is changed to all task execution completion state.

Mode three: and under the condition that any asynchronous folder replication subtask fails to execute, changing the task state into a task execution failure state.

If any asynchronous folder replication subtask transmits an execution failure condition in execution, before the task exits, the task state of the folder replication task in the task database table is changed into a task execution failure state, and the task database table records a target asynchronous folder replication subtask corresponding to a breakpoint of the task according to an execution queue in the task information of the folder replication task, so that the target asynchronous folder replication subtask which fails to be executed can be restarted through the task execution failure state and the task breakpoint in the follow-up, and by the mode, the success rate of task execution is improved, and the problem of data consistency after the file replication failure is guaranteed.

S209, canceling the pointing relation after detecting that the task state of the folder copying task is the completion state of all task execution.

The method comprises the steps of calling a task database table according to a preset period, detecting the task state of a current folder replication task, determining that replication is completed after detecting that the task state of the folder replication task is the completion state of all task execution, and canceling the pointing relation of a target folder so that the subsequent operation on the target folder can be normally executed on the target folder. In the embodiment where the pointing relationship is a soft link, canceling the pointing relationship is specifically: the soft link is deleted.

The duration of the preset period may be set arbitrarily according to a specific implementation manner, for example, set to 20ms.

Specifically, S206-S209 are one implementation of S102, and specifically, S102 has other implementations, which are not limited herein. And, in the case that the number of subfile objects included in the source folder is large, the method may be executed in the manner of S206-S209, and in the case that the number of subfile objects included in the source folder is small, S206-S209 may be omitted, and all the subfile objects to be copied may be directly packaged into a single task for execution.

S210, deleting task identification, task information and association relation of the folder replication task in the task database table.

After the task execution is determined to be completed, in other words, after the task state of the folder replication task is detected to be all the task execution completion state, the task identification, the task information and the association relation of the folder replication task are deleted from the task database table, so that the redundant information of the task database table can be reduced, and the completed folder replication task can be prevented from being triggered by mistake.

S211, setting the folder state of the target folder to be a copy completion state.

After determining that the task execution is completed, in other words, after detecting that the task state of the folder replication task is all the task execution completion state, the folder state of the target folder is set to the replication completion state, so that when the task execution is completed (i.e., the folder state is the replication completion state), the operation for the target folder is directly performed on the target folder, and the change operation can be performed on the target folder and the source folder.

The execution order of S210 and S211 may be changed, and is not limited herein.

Based on the above, the present disclosure further provides an exception handling mechanism for task exceptions in executing a folder replication task. Specifically, based on the third mode S208, S208 further includes:

Step one: and detecting the task state according to a preset period.

The duration of the preset period may be set arbitrarily according to a specific implementation manner, for example, set to 15ms. The first step is to set a periodic abnormality detection period to detect task states and discover task abnormalities in time.

Step two: and carrying out corresponding task processing operation on the folder copying task according to the task state detection condition.

The matching relationship between multiple groups of detection cases and task processing operations can be preset, wherein the detection cases comprise one of the following: the task state is a task execution failure state, and the operation time of copying the subtask of any asynchronous folder exceeds a preset threshold; the task processing operations include one of: and determining a task break point, restarting the target asynchronous folder replication subtask, and restarting the asynchronous folder replication subtask with the operation time exceeding a preset threshold value.

Specifically, in some examples, step two includes the sub-steps of:

and step one, determining a task break point under the condition that the task state is detected to be the task execution failure state.

And step two, determining a target asynchronous folder replication subtask corresponding to the task break point, and restarting the target asynchronous folder replication subtask.

According to the third mode of S208, if any one of the asynchronous folder replication sub-tasks fails to be executed, before the task exits, the task state of the folder replication task in the task database table is changed to a task execution failure state, and the task database table records the target asynchronous folder replication sub-task corresponding to the task interrupt point in the task information of the folder replication task according to the execution queue, so that in the first and second sub-steps a, if the task state is detected to be the task execution failure state, the task interrupt point can be determined through the task database table, and the step folder replication sub-task with the execution failure can be determined to be the target asynchronous folder replication sub-task through the task endpoint, and then the target asynchronous folder replication sub-task with the execution failure is restarted.

Alternatively, step two comprises the sub-steps of:

and B, interrupting the asynchronous folder copying sub-task with the operation time exceeding the preset threshold value under the condition that the operation time of any asynchronous folder copying sub-task is detected to exceed the preset threshold value.

And step B, restarting the asynchronous folder copying subtask with the operation time exceeding a preset threshold value.

The preset threshold is a reference time for judging task jam, and may be set according to specific implementation requirements, for example, may be set to 1 minute.

In some cases, the asynchronous folder replication subtask may exit abnormally, and the task state is not changed to be the task execution failure state, in this case, the task state is kept to be the task execution state, so that the abnormality is not found, therefore, a preset threshold of an abnormal period can be set, after the operation time of the current task in the task data table is determined to exceed the preset threshold, the occurrence of the abnormality of the task can be determined, namely, the interrupt operation is performed on the current asynchronous folder replication subtask, the task state is changed to be the task execution failure state, and a restarting mechanism is triggered, and the asynchronous folder replication subtask with the operation time exceeding the preset threshold is restarted.

By the method, the task abnormality can be found in time and the abnormality interference can be carried out, so that the success rate of task copying and the consistency of data are ensured.

It should be noted that, the first step and the second step may be performed at any period of time (specifically, periodically performed according to a preset period) in the whole process after S207 and before S209, which is not limited herein.

Based on the foregoing, the present disclosure also provides a mechanism for protecting the file integrity of the source folder and the target folder during the execution of the folder replication task. Specifically, referring to fig. 3, fig. 3 is a flowchart illustrating a step of protecting a copy file in a method for copying a folder provided in the present disclosure. Based on the above embodiment in which the folder status is set in S205, the method for copying a folder provided in the present disclosure further includes:

s201', determining a folder state of the target folder in response to a file change operation for any one of the source folder, the target folder and any one of the target folder.

S202', determining the execution mode of the file change operation according to the state of the folder.

In order to protect the integrity of the source folder and the files therein, the target folder and the files therein, whether the copying task is completed or not can be known through the folder state of the target folder, and in the case that the copying task is not completed, the operation (namely, the file changing operation) which can damage the integrity of the source folder and the files therein is not performed, and only the checking operation is allowed to be performed, so that the integrity of the files is protected, the files are prevented from being deleted by mistake before the copying task is not completed, and the reliability of the copying method of the folders provided by the embodiment of the disclosure is improved.

Specifically, S202' includes the following cases:

(1) And executing file changing operation under the condition that the folder state is determined to be the copy completion state.

If the folder state is detected to be the copy completion state, the completion of the execution of the copy task can be determined, and in this case, the folder is not locked any more, so that the file change operation can be normally executed.

(2) In the case where it is determined that the folder state is the copy incomplete state, the execution mode of the file change operation is determined according to any one of the following.

Mode one: and prohibiting the execution of the file change operation.

Mode two: generating an asynchronous file change task according to the file change operation; and executing the asynchronous file change task under the condition that the folder state is detected to be the copy completion state.

If the folder state is detected to be in a non-copy completion state, namely the copy task is not executed and completed, at the moment, the integrity of the file needs to be protected, the execution operation can be directly forbidden, or an asynchronous file change task is generated for the change operation, after the asynchronous file change task is generated, the related information of the asynchronous file change task can be stored in the task database table for queuing, and when the folder state is detected to be in the copy completion state, the asynchronous file change task is executed according to the queuing sequence, and the related information of the asynchronous file change task is deleted from the task database table after the execution is completed.

The file change operation at least comprises the following steps: any one of the operations of a delete operation, a transfer operation, and the like.

It should be noted that S201 'and S202' may be performed at any period during the document copying process, and are not limited herein.
