DETAILED DESCRIPTION

[0011] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0012] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0013] The program update method, electronic device, storage medium and program product provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0014] Figure 1 A program update method provided by an embodiment of the present application is shown, and the method can be executed by an electronic device. In other words, the method can be executed by software or hardware installed in the electronic device, and the method includes the following steps: Step 102: when a first code of a program under development is updated to a second code, a difference segment between the first code and the second code is obtained.

[0015] In the embodiment of the present application, the program under development may be a medium-sized program or a small program, and the program under development is not specifically limited here. Specifically, when updating the program under development, that is, when the first code of the program under development is updated to the second code, it is necessary to obtain the difference fragment between the first code and the second code.

[0016] In one implementation, obtaining the difference segment between the first code and the second code includes: incrementally compiling the second code to find a target file with changes; and finding the difference segment between the first code and the second code from the target file.

[0017] Specifically, when updating the program under development in the development tool, the second code of the program under development can be incrementally compiled when it is running. The development tool can find the target files that have changed in the program and create a list of all the files that have changed to obtain a list of files that have changed. For each target file that has changed, the Histogram algorithm is used to compare the difference fragments between the first code and the second code at the same position before and after the change when the program is running, so as to obtain all the difference fragments in each file, that is, the difference fragments between the first code and the second code.

[0018] Step 104: construct an information matrix according to the operation information corresponding to the difference fragments.

[0019] Specifically, the operation information indicates the operation direction of updating the first code to the second code. After obtaining the difference fragments, an information matrix can be constructed according to the operation information corresponding to the difference fragments.

[0020] In one implementation, before constructing the information matrix according to the operation information corresponding to the difference fragment, it also includes: creating a pattern string corresponding to the difference fragment in the first code; creating a target string corresponding to the difference fragment in the second code; and initializing the information matrix according to the target string and the pattern string.

[0021] In an embodiment of the present application, for a difference segment with a difference, two strings and an information matrix corresponding to each difference segment are initialized. Specifically, there can be multiple difference segments, and the number of difference segments is not limited here. First, create a target string T corresponding to the second code of the difference segment after the program is updated when the program is running, and the other is a pattern string P corresponding to the first code of the difference segment before the program is updated when the program is running. Initialize an information matrix D, the number of rows of which is the length of the pattern string P plus 1, and the number of columns is the length of the target string T plus 1. Set the first column of the information matrix D (i.e., D[0][j], where j is from 0 to the target string length) to consecutive integers, starting from 0. Initialize a variable x to indicate the current matching position, with an initial value of 0. At each position (i, j) of the information matrix D, in addition to recording the minimum edit distance, an additional value is also recorded to indicate from which direction the current position is reached, which can be represented by the following symbols: D[i][j]: edit distance of the current position. INSERT: indicates reaching the current position from the top, indicating an insert operation. DELETE: indicates reaching the current position from the left, indicating a delete operation. MATCH: indicates reaching the current position from the upper left, indicating a match operation. REPLACE: indicates reaching the current position from the upper left and upper right, indicating a replace operation.

[0022] In one implementation, constructing an information matrix based on the operation information corresponding to the difference fragment includes: comparing the first character at the jth position of the target string with the second character at the ith position of the pattern string; when the first character is equal to the second character, filling the value of the element in the i+1th row and j+1th column of the information matrix as the operation information; when the first character is not equal to the second character, filling the minimum value of the value of the element in the i+1th row and j+1th column, the value of the element in the i+1th row and j+1th column, and the value of the element in the i+1th row and j+1th column in the information matrix plus 1 as the operation information into the element in the i+1th row and j+1th column of the information matrix, until the entire information matrix is ​​filled, wherein i and j are integers greater than or equal to 0.

[0023] Specifically, using the above-mentioned initialized target string, mode string, etc., the same positions in the two strings corresponding to the difference fragments before and after the mini program is updated are compared one by one, so as to fill the operation information obtained by comparison into the information matrix.

[0024] Specifically, the first character at the jth position of the target string and the second character at the ith position of the pattern string can be compared; when the first character is equal to the second character, the value of the element at the ith row and jth column in the information matrix is ​​used as the operation information to fill in the element at the i+1th row and j+1th column in the information matrix; when the first character is not equal to the second character, the minimum value of the value of the element at the ith row and jth column, the value of the element at the i+1th row and j+1th column, and the value of the element at the ith row and j+1th column in the information matrix plus 1 is used as the operation information to fill in the element at the i+1th row and j+1th column in the information matrix until the entire information matrix is ​​filled. For example, the following takes the filling of difference segment 1 into information matrix D1 as an example for description, starting from the first character of pattern string P corresponding to difference segment 1, each character of pattern string P is traversed. Correspondingly, starting from the first character of target string T corresponding to difference segment 1, each character of target string T is traversed.

[0025] Compare the target string character T[j] corresponding to the difference segment 1 with the corresponding pattern string character P[i] according to the following rules, and calculate the value of D[i+1][j+1], where i and j are integers greater than or equal to 0: If T[j] is equal to P[i], then D[i+1][j+1] is equal to D[i][j].

[0026] Otherwise, D[i+1][j+1] is equal to the minimum of the following three values ​​plus 1: D[i][j] (the value of the upper left corner of D[i+1][j+1]); D[i+1][j] (the value to the left of D[i+1][j+1]); D[i][j+1] (the value above D[i+1][j+1]).

[0027] Using the above rules, continue to fill the entire information matrix until all positions in the difference segment 1 are calculated, and obtain the information matrix D1 corresponding to the difference segment 1. Then perform the above steps for other difference segments, that is, fill in the information matrices corresponding to other difference segments, until all difference segments (for example, there are N difference segments) are compared, thereby obtaining the corresponding information matrices D1, D2, D3, ..., DN.

[0028] For the difference segments with differences, two strings and information matrices corresponding to each difference segment are initialized. By comparing the characters in the same position in the two strings, the operation information obtained by the comparison is filled into the information matrix to obtain a complete editing operation sequence. This technology has high accuracy because it accurately captures the differences between the difference segments and can also avoid unnecessary updates, thus saving time and resources. In addition, the maintainability of the information matrix is ​​provided because the operation information is structured and recorded in the information matrix, which is convenient for tracking and debugging.

[0029] Step 106: Determine the editing operation sequence corresponding to the difference segment according to the information matrix.

[0030] Specifically, after obtaining the information matrix, the editing operation sequence corresponding to the difference segment can be determined.

[0031] In one implementation, determining the editing operation sequence corresponding to the difference segment according to the information matrix includes: backtracking the information matrix; in the process of backtracking the information matrix, recording each editing operation according to the direction information to obtain the editing operation sequence.

[0032] Specifically, after filling all information matrices, backtracking can be used to obtain the editing operation sequence corresponding to each information matrix, so that N information matrices obtain their corresponding N editing operation sequences.

[0033] In one implementation, the backtracking of the information matrix includes: starting from the lower right corner of the information matrix and recording the direction information and backtracking toward the upper left corner according to the operation information corresponding to each value in the information matrix.

[0034] Specifically, starting from the lower right corner of the information matrix, the direction information can be recorded and traced back to the upper left corner according to the operation information corresponding to each value in the information matrix defined by the initialization above. During the backtracking process, the editing operation is determined according to the direction information. By recording each editing operation according to the direction information during the backtracking process, a complete editing operation sequence can be obtained, which includes insert, delete, match and replace operations. The embodiment of the present application provides a faster method to obtain the editing operation sequence, thereby accelerating the process of updating and previewing the mini program, reducing the need to recompile the entire mini program, and improving development efficiency.

[0035] Step 108: According to the editing operation sequence, the preview program corresponding to the developing program in the terminal is updated.

[0036] Specifically, after obtaining the editing operation sequence, the editing operation sequence may be sent to a terminal for previewing the program, thereby updating the preview program corresponding to the program under development in the terminal.

[0037] The program update method provided by the embodiment of the present application obtains the difference fragment between the first code and the second code when the first code of the program under development is updated to the second code; constructs an information matrix according to the operation information corresponding to the difference fragment, and the operation information indicates the operation direction of updating the first code to the second code; determines the editing operation sequence corresponding to the difference fragment according to the information matrix; and updates the preview program corresponding to the program under development in the terminal according to the editing operation sequence, so as to improve the development efficiency of the program. By filling the difference fragments that have changed after compilation into the setting information matrix, the information matrix records the direction information of the editing operation, and finally the complete editing operation sequence can be obtained by backtracking according to the direction information to execute the instruction to update the specified file, thereby completing the program update operation. The time and workload of program update are significantly reduced. In addition, since only the difference fragments that have changed need to be updated, it reduces the cost of the overall update operation. This is beneficial to both developers and end users because they can get the latest version of the program faster.

[0038] In one implementation, updating the preview program corresponding to the program under development in the terminal according to the editing operation sequence includes: converting the editing operation sequence into a target editing operation sequence of the JSON protocol; and sending the target editing operation sequence to the terminal so that the terminal updates the preview program according to the target editing operation sequence.

[0039] In an embodiment of the present application, a series of command protocols based on the JSON encoding format can be defined, including replacing files, incrementally updating a file, restarting a mini-program, establishing a connection, disconnecting a connection, etc.

[0040] JSON is a lightweight data exchange format that is easy for people to read and write, can exchange data between multiple languages, and is also easy for machines to parse and generate. The commands required in the embodiments of the present application are all defined based on the JSON encoding format to define some JSON format protocol fields. For example, after the obtained editing operation sequence is converted into a command protocol in JSON format, the update operation can be completed by incrementally updating the specified file that has been compiled according to the JSON format editing operation sequence.

[0041] You can establish a WebSocket server and forward the defined JSON command protocol to the WebSocket server to manage the WebSocket connection of the development tool and mobile preview. WebSocket is an extension based on the HTTP protocol. It provides a persistent, two-way communication channel, allowing the server to push data to the client in real time. The WebSocket handshake process generally includes the following steps: 1. The client sends a WebSocket handshake request; 2. The server responds to the handshake request; 3. The client verifies the handshake response; 4. Confirm that the handshake is successful and establish a WebSocket connection.

[0042] In the embodiment of the present application, a WebSocket server is established, and the defined JSON command protocol is forwarded to the WebSocket server for use by the WebSocket server. In addition, a WebSocket connection is established between the mobile terminal and the server through the WebSocket server.

[0043] After compiling the mini program for the first time in the development tool, you can inject a WebSocket client instance into the main process of the mini program base library to send and receive the JSON command protocol in step 1. After compiling the mini program that needs to be previewed on the mobile terminal for the first time in the development tool, establish a WebSocket connection between the development tool and the server through the WebSocket server, so that the compiled JSON command protocol can be received. After compiling the mini program that needs to be previewed on the mobile terminal for the first time in the development tool, establish a WebSocket connection between the development tool and the server through the WebSocket server, so that the compiled JSON command protocol can be sent.

[0044] By using development tools, according to the editing operation sequence corresponding to the information matrix, it is possible to sort out which files need to be modified and where (including insertion, deletion, matching and replacement operations), and convert these operation instructions into a command protocol in JSON format.

[0045] Specifically, the editing operation sequence can be converted into a target editing operation sequence of the JSON protocol, and the converted target editing operation sequence of the JSON protocol can be sent to the mobile terminal by using the established WebSocket connection, and the program can be updated by using the compiled incremental update specified file according to the target editing operation sequence in JSON format to complete the hot update operation of the program. The editing operation sequence is used to update the file through the JSON protocol, which means that the editing operation information is transmitted in a structured format. The JSON protocol is a universal data exchange format that is easy to parse and process. It provides an extensible way to transmit the editing operation sequence, making the process of updating files more flexible and maintainable. This method also facilitates integration with other systems or tools and improves interoperability.
