Description
Technical Field
The invention relates to the field of computers, in particular to a large file simulation method and device.
Background
As operating systems are applied more and more widely, the requirement on stability of the operating systems is higher and higher. Therefore, in developing the operating system, the stability of the operating system needs to be tested. In the process of testing the stability of the operating system, the operating system to be tested is set in different hardware running states, such as: the Central Processing Unit (abbreviated as CPU) occupancy rate is 100%, the memory occupancy rate is 90%, the hard disk space occupancy rate is 100% or the hard disk space occupancy rate is 90%, and the like, and then the operating system is operated to obtain the faults of the operating system in the operating states, solve the faults and improve the stability of the operating system.
In general, in order to obtain failures of an operating system under different hard disk space occupancy rates, before the operating system performs a stability test, a large file is written into a hard disk space of a computer where the operating system is located, and the hard disk space occupancy rate of the computer reaches a size required by the test in a manner of storing the large file, so as to perform a subsequent stability test on the operating system, wherein the large file refers to a single file with a size of Gigabytes (GB) or more.
When writing a large file into a hard disk space of a computer, even when the large file is written into a solid state disk (the read-write speed is 300 mega/s), if the capacity of the solid state disk is 1 Terabyte (TB), the solid state disk needs to be fully filled, which takes 1 hour to implement, and then the stability test can be performed on an operating system. If the hard disk space of the computer is a solid state disk with a size of several TB, or the hard disk of the computer where the operating system is located is a mechanical hard disk with a capacity of 1 terabyte (the read/write speed is 80 mb/sec), the hard disk will be used for several hours if it is full, which will make the test time very long, resulting in low test efficiency.

Referring to fig. 1, it shows a schematic structural diagram of an implementation environment related to a large file simulation method provided by the embodiment of the present invention, where the system includes: a computer hardware system 10 and an operating system 11 running on the computer hardware system.
The computer hardware system 10 constitutes a hardware test environment for stability testing of the operating system 11.
Example one
Referring to fig. 2, the present embodiment provides a large file simulation method, which includes the following steps:
Step 100, the operating system obtains operating system test parameters, wherein the operating system test parameters comprise a hard disk space target occupancy rate, a hard disk space total capacity and a hard disk space used capacity, and the hard disk space target occupancy rate is a hard disk space occupancy rate required to be achieved when the hard disk space is used for testing the performance of the operating system.
The target occupancy rate of the hard disk space is only one of a plurality of operating system test parameters, and according to the stability test requirement of the operating system, a plurality of operating system test parameters can be provided, such as: target memory space occupancy rate, target CPU utilization rate, etc., which are not described in detail herein.
Step 101, according to the target occupancy rate of the hard disk space and the total capacity of the hard disk space, the operating system calculates the target occupancy capacity of the hard disk space.
The operating system can obtain the size of the target file by reading the file information of the target file.
Step 102, according to the target occupied capacity, the operating system modifies the size of the target file in the hard disk space, so that the occupied capacity of the hard disk space reaches the target occupied capacity, and the target file is any file in the hard disk space.
The size of the large file is determined according to the target occupied capacity of the hard disk space and the used capacity of the hard disk space, and the size is usually above Gigabytes (GB).
through the above description, the target occupation capacity of the hard disk space is calculated through the target occupancy rate of the hard disk space, the total capacity of the hard disk space and the used capacity of the hard disk space included in the test parameters of the operating system, and then the size of the target file in the hard disk space is modified according to the target occupation capacity, so that the occupation capacity of the hard disk space reaches the target occupation capacity, the occupancy rate of the current hard disk space is consistent with the target occupancy rate of the hard disk space in the test parameters of the operating system, the process of modifying the size of the target file only takes tens of milliseconds, and a large file is not required to be written into the hard disk for hours, and the operating system can determine that the size of the current hard disk space reaches the test requirement.
Example two
referring to fig. 3, the present embodiment provides a large file simulation method, which includes the following steps:
step 200, the operating system obtains operating system test parameters, wherein the operating system test parameters comprise a hard disk space target occupancy rate, a hard disk space total capacity and a hard disk space used capacity, and the hard disk space target occupancy rate is a hard disk space occupancy rate required to be achieved when the hard disk space is used for testing the performance of the operating system.
The operating system is any operating system with a Linux kernel, such as: an operating system Mac OS X used on the apple computer, an android system used on the mobile terminal and the like.
the operating system can obtain two parameters of the total capacity of the hard disk space and the used capacity of the hard disk space by reading the system information of the computer. The parameter of the target occupancy rate of the hard disk space is a parameter meeting the stability test requirement of the current operating system, and can be input into the operating system by a tester through input equipment of a computer hardware system; or the test result may be recorded in a hardware requirement table set in a hard disk of the computer hardware system in advance, before the test, a tester may open the hardware requirement table through an input device of the computer hardware system, and select a parameter of the current operating system stability test requirement in the hardware requirement table.
The target occupancy rate of the hard disk space is only one of a plurality of operating system test required parameters recorded in the hardware requirement table, and a plurality of operating system test parameters are also recorded in the hardware requirement table, which is not described in detail herein.
The hardware requirement table can be opened by a tester in the form of a table or a program on the operating system, so that the tester can select the operating system test parameters meeting the stability test requirement of the current operating system from a plurality of operating system test parameters.
the operating system test parameters may include any parameter for operating system stability test, in addition to the target occupancy rate of the hard disk space, the total capacity of the hard disk space, and the used capacity of the hard disk space, which is not described herein any more.
Wherein, the parameter range of the target occupancy rate of the hard disk space is 0% to 100%.
Step 201, according to the target occupancy rate of the hard disk space and the total capacity of the hard disk space, the operating system calculates the target occupancy capacity of the hard disk space.
Specifically, after acquiring two parameters, namely the target occupancy rate of the hard disk space and the total capacity of the hard disk space, the operating system calls a processing process of the CPU to calculate the product of the target occupancy rate of the hard disk space and the total capacity of the hard disk space, and the result obtained by calculation is used as the target occupancy capacity of the hard disk space.
the target occupied capacity of the hard disk space obtained through calculation is the used capacity of the hard disk space meeting the stability test requirement of the current operating system.
Such as: the target occupancy rate of the hard disk space is 92%, the total capacity of the hard disk space is 500GB, and then the target occupancy capacity of the hard disk space obtained through calculation is 460 GB.
Step 202, according to the target occupied capacity, the operating system modifies the size of the target file in the hard disk space, so that the occupied capacity of the hard disk space reaches the target occupied capacity, and the target file is any file in the hard disk space.
Specifically, the flow of step 202 is specifically described by step 2021-step 2022.
Step 2021, according to the target occupied capacity of the hard disk space and the used capacity of the hard disk space, the operating system obtains the variable quantity of the size of the target file.
specifically, the operating system calls a processing process of the CPU to calculate a difference value between the target occupied capacity of the hard disk space and the used capacity of the hard disk space according to the target occupied capacity of the hard disk space and the used capacity of the hard disk space, and uses the calculated difference value as a variable quantity of the size of the target file.
If the variable quantity of the size of the target file is a positive value, the target occupied capacity of the hard disk space is larger than the used capacity of the hard disk space, and the obtained variable quantity of the size of the target file is to increase the used capacity of the hard disk space where the target file is located, so that the requirement of the target occupied capacity of the hard disk is met; if the variable quantity of the target file size is a negative value, the target occupied capacity of the hard disk space is smaller than the used capacity of the hard disk space, and the obtained variable quantity of the target file size is to reduce the used capacity of the hard disk space where the target file is located, so that the requirement of the target occupied capacity of the hard disk is met.
The target file size is a variable amount, which is the target file size to be modified, and is usually a value between several tens of GB and several hundreds of GB.
The size of the target file can be set to be larger, even can exceed the hard disk space by a large amount, but the maximum value of the target occupancy rate of the hard disk space is 100%.
Step 2022, according to the obtained variation of the size of the target file, the operating system modifies the size of the target file.
Specifically, the operating system obtains the size of the target file from the file information of the target file, modifies the size of the target file according to the previously obtained variation of the size of the target file to enable the occupied capacity of the hard disk space to reach the target occupied capacity, and enables the target file to rapidly simulate the large file by modifying the size parameter of the target file.
furthermore, after the size of the target file is modified, when the operating system reads the file information of the target file, the size of the target file recorded in the file information of the target file is the size modified according to the variable quantity of the size of the target file, and then the operating system automatically modifies the used capacity of the hard disk space, so that the occupied capacity of the hard disk space reaches the target occupied capacity.
in the specific implementation process, the size of the target file has no absolute size relationship with the size to be modified.
In some cases, in order to discover the effect of large files formed by different types of target files on the stability of the operating system, the file types of the target files may be modified for related tests.
Further, in the embodiment provided by the present invention, the large file simulation method further includes the following steps:
Step 203, according to the test requirement of the operating system performance, the operating system modifies the file type of the target file.
The file types of the target file include, but are not limited to: audio, video, pictures, documents, etc. The file types of the audio include: WAV, MP3, APE, WMA, etc.; the file types of the video include: wmv, asf, asx, rm, rmvb, mpg, mpeg, mpe, 3gp, mov, mp4, m4v, avi, dat, mkv, flv, vob, etc.; the file types of the pictures include: BMP, PCX, JPEG, GIF, TIFF, etc.; the file types of the document include: pdf, word, ppt, txt, etc.
The size of the file is modified, the type of the file is modified, and the performance of an operating system can be simulated when the occupancy rates of different types of files in a specified hard disk are reduced.
optionally, the large file simulation method further includes the following steps:
And step 204, after the performance of the operating system is tested under the condition of the target occupancy rate of the hard disk space, the operating system recovers the size of the target file or deletes the target file.
in some cases, in order to find out the failure of the operating system under the condition that the hardware environment of the computer is relatively extreme, the stability of the operating system is tested when the hard disk space of the computer where the operating system is located is full, but before the test, the hard disk space needs to be verified.
Further, in the embodiment of the present invention, referring to fig. 4, the method for performing hard disk space full verification includes the following steps:
Step 301, the operating system obtains a file write operation instruction.
Specifically, after the operating system modifies the used capacity of the hard disk space to the capacity of the hard disk space, the operating system obtains a file write operation instruction, where the file write operation instruction is used to write a specified file of any size into the hard disk space.
the file writing operation instruction is an instruction sent to an operating system by a tester through input equipment of a computer.
the specific file is pre-stored in any other storage device in the non-hardware test environment, such as: u disk or mobile hard disk.
Step 302, if the file write operation instruction is not responded within the preset time, the operating system determines that the occupancy rate of the hard disk space is 100%.
specifically, the flow of step 302 is specifically described by step 3021 to step 3023.
step 3021, the operating system determines whether the file write operation command is responded within a preset time.
if the operating system judges that the file writing operation instruction is not responded in the preset time, step 3022 is executed.
If the operating system judges that the file writing operation instruction is responded within the preset time, step 3023 is executed.
Specifically, after the operating system obtains the file write operation instruction, the file write operation instruction is transmitted to a hard disk controller of the computer hardware system, and the hard disk controller writes the specified file into the hard disk space according to the file write operation instruction. If the specified file is not written into the hard disk space within the preset time, judging that the file writing operation instruction is not responded; and if the specified file is successfully written into the hard disk space, judging that the file writing operation instruction is responded.
step 3022, if it is determined that the file writing operation instruction is not responded within the preset time, the hard disk controller of the computer determines that the occupancy rate of the hard disk space is 100%, and the step 303 is returned.
Step 3023, if it is determined that the file write operation instruction is responded within the preset time, determining that the hard disk controller of the computer does not determine that the occupancy rate of the hard disk space is 100%.
If the specified file is written into the hard disk space within the preset time, it indicates that the hard disk space does not meet the hardware test requirement of the stability test, and the file size of a certain file in the hard disk space and the used capacity of the hard disk space need to be continuously modified to enable the occupancy rate of the hard disk space to reach 100%.
The length of the preset time can be set differently according to the stability test condition, and is generally any time length from 0 millisecond to 100 milliseconds.
step 303, the hard disk controller of the computer returns the hint code that the hard disk space is full to the operating system.
specifically, if the specified file is not written into the hard disk space within the preset time, the hard disk controller generates a prompt code indicating that the hard disk space is full, then the prompt code indicating that the hard disk space is full is returned to the operating system, and after the operating system obtains the prompt code indicating that the hard disk space is full, the operating system displays the prompt code indicating that the hard disk space is full on a display of the computer in a form of a message popup window so as to inform a tester that the hard disk space of the computer is full at this time, so that the stability of the operating system can be tested.
Optionally, after obtaining the prompt code indicating that the hard disk space is full, the operating system is not limited to notifying the tester in the form of a message popup window, and may also notify the tester that the hard disk space is full in any other manner, which is not described herein any more.
through the description of steps 301 to 303, before the stability test of the operating system is performed, it is verified whether the current hard disk space is full, and when it is determined that the hard disk space is full, the stability test of the operating system is performed, so that the hardware environment for performing the test can meet the test requirement, and the test accuracy is improved.
the contents of the present embodiment are further described by the following examples.
In any operating system with a Linux kernel, in order to test the stability of the operating system when the hard disk is full, the operating system modifies the size of the target file to make the hard disk space where the operating system is located full.
The process of the operating system for modifying the size of the target file comprises the following steps: presetting a first trigger function for calling file information of an acquired target file and a first callback function corresponding to the first trigger function, wherein the first callback function is set with variable quantity of the size of the target file; when the operation of modifying the size of the target file is carried out, the operating system firstly calls a first trigger function to obtain the size of the target file, and after the size of the target file is obtained, the first callback function is executed to modify the size of the target file, so that the usable space of the hard disk space after the size of the target file is modified is 0.
then, in order to ensure that the hard disk space where the operating system is located is full, it is necessary to verify whether the hard disk space is full.
the process of verifying whether the hard disk space is full is as follows: the method comprises the steps of presetting a second trigger function for triggering a file writing instruction and a second callback function corresponding to the second trigger function, wherein the second callback function is used for returning a prompt code indicating that the hard disk space is full, calling the second trigger function by an operating system to trigger the file writing instruction when the operation of verifying whether the hard disk space is full is carried out, and executing the second callback function to return the prompt code indicating that the hard disk space is full when the file cannot be written into the hard disk space, so as to confirm that the hard disk space is full.
the first trigger function may be a vfs _ gettat function, the first callback function may be a vfs _ gettat _ handler function, the second trigger function may be an rw _ verify _ area function, and the second callback function may be an rw _ verify _ area _ handler function.
based on the above description, the large file simulation method provided in this embodiment calculates the target occupation capacity of the hard disk space through the target occupancy rate of the hard disk space, the total capacity of the hard disk space, and the used capacity of the hard disk space included in the operating system test parameters, and then modifies the size of the target file in the hard disk space according to the target occupation capacity, so that the occupancy rate of the hard disk space reaches the target occupation capacity, and the current occupancy rate of the hard disk space is consistent with the target occupancy rate of the hard disk space in the operating system test parameters, and the process of modifying the size of the target file only takes tens of milliseconds, and does not take several hours to write the large file into the hard disk, so that the operating system can determine that the current occupancy rate of the hard disk space has reached the test requirement, and can immediately perform the test of the stability of the operating system, thereby greatly saving the test time of the stability, the test efficiency of the stability of the operating system is improved.
