Detailed Description
In order to make the objects, features and advantages of the present invention more comprehensible, the technical solutions in the embodiments of the present invention are described in detail below with reference to the accompanying drawings, and it is apparent that the embodiments described below are only some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, an embodiment of a method for generating an installation package according to an embodiment of the present invention may include:
and step S101, monitoring whether codes of all functional modules in the target engineering are changed.
The target project is a code project of a specified application program.
The target engineering in the present embodiment is divided by functional modules, for example, may be divided by a communication module, an image processing module, an audio processing module, a camera module, … …, and the like.
In a specific implementation of this embodiment, whether the codes of the functional modules in the target engineering are changed may be monitored through steps shown in fig. 2.
Step S201, reading the first message digest values of the codes of the respective functional modules from a preset database.
The first message digest value is a message digest value obtained by calculating the code of the functional module before the code is changed by using a preset message digest algorithm.
Specifically, the first message digest values of the codes of the respective functional modules may be calculated in advance, respectively, according to the following formulas:
MsgDigVal′ n ＝MsgDigFunc(ModCode′ n )
wherein N is the serial number of the functional modules, N is more than or equal to 1 and less than or equal to N, N is the total number of the functional modules in the target engineering, modCode' n The MsgDigFunc is the message digest algorithm, and MsgDigVal 'is the original code of the nth functional module in the target engineering, namely the code of the functional module before the current monitoring' n A first message digest value that is the code of the nth functional module in the target project.
The message digest algorithm in this embodiment includes, but is not limited to, the MD5 algorithm, the SHA-1 algorithm, and various variations thereof.
After the first message digest value of the code of each functional module is pre-calculated, it may be stored in a database for use in a subsequent comparison.
Step S202, calculating second message digest values of codes of the functional modules respectively.
Specifically, the second message digest values of the codes of the respective functional modules may be calculated according to the following formulas:
MsgDigVal n ＝MsgDigFunc(ModCode n )
wherein N is the serial number of the functional modules, N is more than or equal to 1 and less than or equal to N, N is the total number of the functional modules in the target engineering, modCode n For the code of the nth functional module in the target engineering, msgDigFunc is the message digest algorithm, and MsgDigVal n A second message digest value that is the code of the nth functional module in the target project.
Step S203, determining whether the first message digest value and the second message digest value of the code of the module to be monitored are consistent.
The module to be monitored is any one functional module in the target engineering.
Since the first message digest value is the message digest value of the code of the function module before the current monitoring, and the second message digest value is the message digest value of the code of the function module during the current monitoring, if the code is not changed, the two should be identical, if the code is changed, the two should be different, so that the first message digest value and the second message digest value of the code of the module to be monitored can be compared, if the first message digest value and the second message digest value of the code of the module to be monitored are identical, step S204 is executed, and if the first message digest value and the second message digest value of the code of the module to be monitored are not identical, step S205 is executed.
And step S204, judging that the code of the module to be monitored is not changed.
Step S205, the code of the module to be monitored is judged to be changed.
In a specific implementation of this embodiment, whether the codes of the functional modules in the target engineering are changed may be monitored through the steps shown in fig. 3.
Step 301, a code change record of the module to be monitored is read from a preset code change log.
The module to be monitored is any one functional module in the target engineering.
The code change log is used for recording each modification to the code, and the terminal equipment automatically records each modification as a code change record, wherein the code change log comprises a plurality of code change records. Each code change record may include the following three departments: modification time, modification object (i.e., which functional module is targeted), and specific modification content.
For example, the code change log may be represented in tabular form as follows:
and step S302, judging whether a newly added code change record exists after the reference time according to the code change time in the code change record of the module to be monitored.
And the reference time is the time when the original installation package is generated by packing the target engineering before the code is changed.
If the code change record of the module to be monitored does not have the code change record newly added after the reference time, step S303 is executed, and if the code change record of the module to be monitored has the code change record newly added after the reference time, step S304 is executed.
And step S303, judging that the code of the module to be monitored is not changed.
And step S304, judging that the code of the module to be monitored is changed.
It should be noted that, the method of message digest checking shown in fig. 2 and the method of code change log recording shown in fig. 3 are merely two specific ways of monitoring whether the codes of the functional modules in the target engineering are changed, and in practical application, other monitoring ways may be selected according to practical situations, which is not limited in this embodiment.
Step S102, if the code of any one of the functional modules in the target engineering is changed, the preset influence indexes of the functional modules are obtained.
In this embodiment, the impact index of each functional module is mainly evaluated by the number of abnormal times of each functional module in the actual use process of the application program, that is, if the number of abnormal times of a certain functional module in the actual use process of the application program is greater, the code in the functional module needs to be modified more urgently, and if the number of abnormal times of a certain functional module in the actual use process of the application program is less, the code in the functional module needs to be modified less urgently, and if the number of abnormal times of the certain functional module in the actual use process of the application program is less, the impact index of the functional module is also lower.
Further, the influence of time needs to be considered, since the code is continuously changed, some anomalies are repaired along with the change of the code, the anomalies are no longer generated later, and some anomalies are generated along with the change of the code, so that the longer the time period, the less the influence is on the current, and the closer the time period, the more the influence is on the current.
Specifically, as shown in fig. 4, the preset process of the impact index may include:
step S401, acquiring a history usage record of the application program in a preset statistical period from the database.
The statistical period can be set to 1 month, 2 months, 3 months, half year, one year or other values according to actual conditions, and the data which is too far is not significant in reference to the data, so that the data is generally set within one year.
Step S402, dividing the statistical period into T subperiods.
T is a positive integer, and the value of T can be set according to practical situations, for example, the value of T can be set to be 5, 10, 20 or other values. Note that the larger the value of T is, the larger the calculation amount is, but the higher the calculation accuracy is; the smaller the value of T, the larger the calculation amount, but the lower the calculation accuracy, the two needs to be weighted according to the actual situation.
And step S403, counting the abnormal times of each functional module in each sub-period according to the history use record.
And S404, respectively calculating the influence indexes of the functional modules.
Specifically, the impact index of each functional module may be calculated according to the following equation:
wherein T is the sequence number of the subperiod, T is more than or equal to 1 and less than or equal to T, and AbnNum n,t Impdieg is the number of times an abnormality occurs in the nth functional module within the nth subperiod n Is the impact index of the nth functional module.
And step S103, calculating the code change amount of the target project according to the influence indexes of the functional modules and whether the codes of the functional modules are changed.
Specifically, the code change amount of the target project may be calculated according to the following formula:
wherein StdScore is a preset standard score, modBool n Detecting a Boolean value for an nth functional module, an
ChangeScore is the code change amount of the target project.
And step S104, judging whether the code change amount of the target project is larger than a preset threshold value.
The threshold may be set according to the actual situation, for example, it may be set to 50, 100, 200 or other values.
If the code change amount of the target project is smaller than or equal to the threshold value, the code change amount of the target project is not large enough, and the process returns to the step S101 and the following steps until the code change amount of the target project is larger than the threshold value.
If the code change amount of the target project is greater than the threshold, it is indicated that the code change amount of the target project is already sufficiently large, and step S105 is performed.
And step 105, packaging the target engineering to generate an application program installation package, and replacing the original installation package in the appointed download address.
The original installation package is an application program installation package generated by packaging the target engineering before the code is changed.
The download address may be an address in each application mall for a user to download an installation package of the installation application.
In summary, the embodiment of the invention determines whether the codes of each functional module in the code engineering are changed in an automatic monitoring manner, automatically packages and generates the application program installation package when the changes reach a certain degree, replaces the original installation package in the designated download address, does not need any manual intervention in the whole process, and is realized in an automatic manner, so that the operation efficiency is greatly improved. In addition, the embodiment of the invention introduces the code change amount to measure the change condition of the code engineering, when the code change amount is smaller, the packing operation is not executed, and only when the code change amount is large enough, the packing operation is executed, thereby greatly reducing the update frequency of the application program installation package, reducing the times of downloading and updating by a user and obtaining better user experience.
It should be understood that the sequence number of each step in the foregoing embodiment does not mean that the execution sequence of each process should be determined by the function and the internal logic, and should not limit the implementation process of the embodiment of the present invention.
