Detailed Description
Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings, in which various details of the embodiments of the present invention are included to facilitate understanding, and are to be considered merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
The embodiment of the invention provides a method for generating a unique value, which can be applied to an application scene of performance test, wherein in the scene, when script codes of the performance test are called each time, the unique value called each time is generated to serve as the entry of the performance test codes.
As shown in fig. 1, the method for generating the unique value includes: step S101 and step S102. In step S101, a unique value prefix is obtained from the server IP and the subnet mask of the test executor of the test program, and the process number and the thread number of the test program.
Server IP and subnet masks may be used to distinguish between different test executors, i.e., servers, process numbers and thread numbers may be used to distinguish between different process numbers and thread numbers on a test executor. Thus, the unique value prefix is unique to a test program executing on a thread within a process on a server.
Further, in step S102, the number of times of execution of the test program is accumulated as a unique value suffix during the execution of the test program, and a unique value for the current test program execution is generated from the unique value suffix and the unique value prefix of the current test program execution.
After the operating system starts the process, a thread local variable is initialized for the thread for counting the number of calls, the value being initialized to 0. When the thread calls the test program (script code of performance test), the call number variable in the thread is accumulated by 1, then the performance test code is called, and the above process is repeated until the performance test is finished.
For a test program executed on a thread in a process on a server, the position value suffix of each execution is unique, so that the unique value is obtained through the combination of the unique value prefix and the suffix, and the test program is unique for any test program when executing each time.
In one embodiment of the invention, the unique value prefix includes: server prefix number, process prefix number, and thread prefix number.
In step S101, the process of obtaining the unique value prefix according to the server IP and the subnet mask of the test executor of the test program, and the process number and the thread number of the test program is specifically:
when the process of the test program is started, the server IP and the subnet mask of the test execution machine of the test program are obtained, the number of the server prefixes is generated, the process number of the test program is obtained, and the number of the process prefixes is generated.
The process of generating the server prefix number specifically includes: first, each of the numbers of the server IP and the subnet mask is converted into a binary number of a set number of bits, which is 8 bits or more. Then, each binary number of the server IP is subjected to OR operation with the corresponding binary number of the subnet mask to obtain an OR operation result, and each binary number of the OR operation result is subjected to XOR operation with the corresponding binary number of the subnet mask to obtain an XOR operation result.
And converting the exclusive-or operation result into decimal numbers, and summing all the numbers to obtain the server prefix number.
When the performance test is executed, different performance test executors are allocated to perform concurrent performance tests. At the start of the performance test procedure, the IP of its server and the subnet mask, e.g., IP address 192.168.0.100, are first obtained, the subnet mask being 255.255.255.0. Both are converted into binary numbers, 8 bits per group, with the insufficient positions preceded by 0.
The IP address is: 11000000.10101000,00000000.01100100;
the subnet mask is: 11111111.11111111.11111111.00000000;
the two are bit or operated, and the result is 11111111.11111111,11111111.01100100;
and performing exclusive OR operation on the result and the subnet mask again to obtain:
00000000.00000000.00000000.01100100；
finally, the binary system is converted into a 10-system number which is 0.0.0.100, and each group of numbers is added, namely 0+0+0+100 is 100, and the sum result is taken as the server prefix number of the unique value, and the value is used for distinguishing the unique value generated by different servers and is put into a global variable.
After the thread of the test program is started, the thread number of the test program is obtained, and the thread prefix number is generated.
The present invention is directed to processing an IP and a subnet mask of a server, and has a main object to shorten an address as much as possible while maintaining the uniqueness of the IP and the subnet mask of the server.
After the operating system starts the process, at least one main thread is provided, and a multithreading is started during performance test to achieve the aim of better concurrency, and the real performance calling environment can be simulated truly.
The thread will then initialize a thread local variable for the call count, which is initialized to 0.
In one embodiment of the present invention, the process of generating the unique value executed by the present test program according to the unique value suffix and the unique value prefix executed by the present test program specifically includes: and forming a character string from the number of server prefixes, the number of process prefixes, the number of thread prefixes and the execution times of the test program executed at the present time to generate a numerical unique value, wherein an interval number is arranged between every two numbers in the character string to distinguish the number of server prefixes, the number of process prefixes, the number of thread prefixes and the execution times in the character string.
For example, the string is a server prefix value+0+process number prefix value+0+thread number prefix value+0+number of calls, and the middle 0 value is an interval number, which is used to distinguish different data items, so as to avoid the situation that the result is not unique after the data of different data items are combined, for example, the process number is 101, the thread number is 11, and the process number is 1011, and the thread number is 1, if the data items are not distinguished, the result is 10111, and for related variables in the scheme, no number of 0 head exists, so that the number 0 is adopted as the interval number of the data items, and the characteristic that the whole is unique data is not affected.
The method for generating the unique value provided by the invention has the advantages that the accumulation process is carried out in each thread, the accumulation locking is not needed, the time loss of remote equation process call is avoided, the application program interface of the calling operation system is carried out once when the process and the thread are initialized, the performance test is not influenced, and the execution time of the performance test script is not needed to be considered. Because the unique value does not adopt a time sequence value, the final unique value has smaller length and can be suitable for more scenes.
For non-numeric unique value generation, the present scheme may also compress the decimal digital conversion. The compression method is as follows: converting the generated unique value into a set binary number, setting the binary number to be larger than decimal, and replacing each digit of the set binary number with a non-numeric character according to the numeric value of each digit of the set binary number to obtain a non-numeric unique value.
And giving different characters according to the set number size of each digit of the set system according to the conversion rule of the compression dictionary to obtain a result character string, namely the unique value code after compression.
The compression process is executed before the performance test script is called, remote procedure call is not needed, the running time of performance test is not affected, and as the whole compressed character string is shortened, a part of network bandwidth can be saved, and especially when the generated unique value does not generate unique data in the performance test script, the requirement of limiting the length of the unique value of some service data can be met.
The embodiment of the present invention further provides an apparatus for generating a unique value, as shown in fig. 2, the apparatus 200 includes: a prefix acquisition module 201 and a unique value generation module 202.
The prefix acquisition module 201 is configured to obtain a unique value prefix according to a server IP and a subnet mask of a test executor of the test program, and a process number and a thread number of the test program.
The unique value generating module 202 is configured to accumulate the execution times of the test program as a unique value suffix during the execution of the test program, and generate the unique value executed by the current test program according to the unique value suffix and the unique value prefix executed by the current test program.
In the present invention, the unique value prefix includes: server prefix number, process prefix number, and thread prefix number.
The prefix acquisition module is further used for acquiring the server IP and the subnet mask of the test execution machine of the test program when the process of the test program is started, generating the server prefix number, acquiring the process number of the test program and generating the process prefix number.
After the thread of the test program is started, the thread number of the test program is obtained, and the thread prefix number is generated.
In the present invention, the unique value generation module is further configured to convert each of the numbers of the server IP and the subnet mask into a binary number of a set number of bits, the set number of bits being 8 bits or more.
And performing OR operation on each binary number of the server IP and the corresponding binary number of the subnet mask to obtain an OR operation result, and performing exclusive OR operation on each binary number of the OR operation result and the corresponding binary number of the subnet mask to obtain an exclusive OR operation result.
And converting the exclusive-or operation result into decimal numbers, and summing all the numbers to obtain the server prefix number.
In the invention, the unique value generating module is further used for forming a character string from the number of server prefixes, the number of process prefixes, the number of thread prefixes and the execution times of the test program executed at the present time to generate a numerical unique value, and interval numbers are arranged between every two numbers in the character string to distinguish the number of server prefixes, the number of process prefixes, the number of thread prefixes and the execution times in the character string.
In the invention, the unique value generation module is further used for converting the numerical unique value into a set system number, wherein the set system is larger than decimal.
And replacing each digit of the set digit with a non-numeric character according to the numerical value of each digit of the set digit to obtain a non-numeric unique value.
