S10, when performing the gradation upgrade, the file format of the binary file is configured as the target format.
The gray scale upgrading is a local upgrading mode, and adverse effects caused by the upgraded program bug can be reduced to the greatest extent.
The traditional binary file does not support the gray scale upgrading, and when the program version is inconsistent with the file version, the situation of disordered analysis or abnormal program occurs.
Therefore, the present embodiment reconfigures the file format of the binary file, and uses the file as a new format of all the binary files after the gray scale upgrade.
Specifically, the file format of the configuration binary file as the target format includes:
configuring a first field for recording a message header size of the binary file;
configuring a second field for recording a line data mode of the binary file;
when the line data mode is a fixed line width mode, configuring a third field for recording the fixed line width of each line of data of the binary file, and adding the first field, the second field and the third field in a message header of the binary file; or
And when the line width mode is a non-fixed line width mode, adding the first field and the second field in a message header of the binary file, respectively configuring each fourth field for recording the line width of each line of data of the binary file, and correspondingly adding each fourth field at the initial position of a message body of each line of data of the binary file.
The fixed line width mode refers to that each line of data of the binary file has the same line width, that is, the length of each line of data is the same.
The non-fixed line width mode means that each line of data of the binary file does not have the same line width, that is, the length of each line of data is the same and also different.
In this embodiment, other fields may also be added to the message header of the binary file according to actual requirements. For example: a field representing a partition number (which can be adjusted according to actual service requirements) can be added, or a field representing a node name can be added, or a field representing signature information can be added, and the like.
Taking the line data mode as the fixed line width mode as an example, a fixed length (53 bytes) field is added as a message header, and then the first 53 bytes of the first message starting from the 54 th byte as the message header may respectively include the following fields:
[0,8) bytes (i.e., the first field): the first 8 bytes are used to define the header size, here 53;
[8,9) bytes (i.e., the second field): 1 byte is used to define a row data pattern;
[9,41) bytes: 32 bytes are used for defining signature information such as node names or file descriptions;
[41,49) bytes (i.e., the third field): 8 bytes are used to define the length of each line of data (from which old version programs can automatically calculate the starting index of the next line of messages);
[49,53) bytes: the last 4 bytes are used to define the total number of data lines of the binary file.
Taking the row data mode as the non-fixed row width mode as an example, the third field may be deleted from the message header in the above example, and a corresponding fourth field may be added at the beginning byte of each row of data in the message body. For example: the fourth field may be 4 bytes, representing the length of each row of data.
The length of each row of data in the binary file is determined by reconfiguring the file format of the binary file, so that the program of any new or old version can analyze the binary file according to the length of each row of data, and the problem of messy message bytes is avoided.
And S11, when detecting that the old version program receives any binary file, determining the any binary file as a target file.
The arbitrary binary file may be a file redefined after the gray scale is upgraded, that is, a file with a newly added field at a suffix of each row of records. For such newly defined files, in the conventional parsing scheme, when the old version program parses the fields built in the program, the newly added field error is parsed into the starting byte of the next record, and actually, the newly added field is the last byte of the current record, which may cause a parsing error.
The arbitrary binary file may also be a file that is not redefined after the grayscale is upgraded, and at this time, the program of any version, whether it is a new version or an old version, may perform normal parsing on the arbitrary binary file.
S12, analyzing the message header of the target file according to the target format to obtain the line data mode of the target file.
In this embodiment, the analyzing the message header of the target file according to the target format to obtain the line data pattern of the target file includes:
reading the second field from the message header of the target file according to the target format;
and determining the line data mode of the target file according to the data content of the second field.
Wherein the second field is defined in a header of the target file for representing a line data pattern of the target file.
Wherein the row data pattern may include, but is not limited to: fixed line width mode, non-fixed line width mode.
And S13, determining the length of each line of data in the target file according to the line data mode.
In this embodiment, the determining the length of each line of data in the target file according to the line data pattern includes:
when the line width mode is the fixed line width mode, reading the third field from the message header of the target file, and determining the length of each line of data in the target file according to the data content of the third field; or
And when the line data mode is the non-fixed line width mode, reading a fourth field of each line of data from the message body of the target file, and determining the length of each line of data in the target file according to the data content of the fourth field of each line of data.
That is, when the line data pattern is the fixed line width pattern, since each line of data has the same line width, the length of each line of data can be obtained by directly obtaining the data content of the corresponding field from the message header.
When the line data mode is the non-fixed line width mode, the length of each line of data may be different, so that the data content of the corresponding field of the message body of each line of data may be read to obtain the length of each line of data respectively.
And S14, determining the initial index of each line of data according to the length of each line of data.
In this embodiment, the determining the start index of each line of data according to the length of each line of data includes:
reading the first field from a message header of the target file;
determining the message header length of the target file according to the data content of the first field;
determining the initial position of the message body of the target file according to the length of the message header as the initial index of the first line data of the target file;
determining the length of the head line data according to the length of each line of data;
calculating the difference value between the length of the head line data and the length of the message header to obtain the length of the message body of the head line data;
determining the length of each line of data as the message body length of each line of data from the second line of data;
and splitting the message body according to the length of the message body of each line of data to obtain the initial index of each line of data.
For example: when the length of the message header is 50 bytes, starting from the 51 th byte of the first line data as the initial index of the first line data of the target file, when the length of the first line data is determined to be 100 bytes, the length of the message body of the first line data is 100-50=50 bytes, at this time, the initial index of the second line of data is 101 th byte, if the length of the second line of data of the message body is determined to be 100, starting from the 101 th and 200 th bytes as the message body of the second line of data, the initial index of the third line of data is 201 th byte, and so on, the initial index of each line of data is obtained.
And S15, analyzing the target file by using the old version program according to the initial index of each line of data.
In this embodiment, the parsing the target file according to the start index of each line of data by using the old version program includes:
acquiring the length of an analyzable field of each line of data of the old version program;
for each line of data, when detecting that the length of the field analyzed by the old version program reaches the length of the corresponding analyzable field, skipping the current line of data, and determining the next line of data of the current line of data according to the initial index of each line of data;
and continuing to analyze the target file from the next line of data.
It will be appreciated that the old version program will configure the parse-able field length for each row of data and parse the binary file according to the parse-able field length for each row of data.
For example: when the resolvable field length of each line of data of the old version program is 100 bytes, in the resolving process, if the current line of data has 200 bytes in total but the resolving field length of the current line of data reaches 100 bytes, the resolving of the current line of data is stopped, and the next line of data is directly jumped to continue resolving, so as to avoid invalid resolving, realize the compatibility of the old version program to the newly defined binary file, and avoid resolving errors.
Moreover, since fields which are not analyzed and skipped in each line of data are newly added fields, the old version program cannot process the fields, so that even if the fields are not analyzed, the execution of the old version program is not influenced, program errors are avoided, and the analysis efficiency is improved.
Moreover, the new version program has adaptability to the binary file newly defined after the gray scale is upgraded, so that the binary file format reconfigured by the embodiment can realize the up-down compatibility of the new version program and the old version program after the gray scale is upgraded, the flexibility and the adaptability of the gray scale upgrade are increased, and the new version program has a higher application prospect in the fields of stock exchange trade systems and the like.
According to the technical scheme, the method can configure the file format of the binary file as the target format to assist in file analysis when gray scale upgrading is executed, determine any binary file as the target file when an old version program is detected to receive any binary file, analyze the message header of the target file according to the target format to obtain the line data mode of the target file, determine the length of each line of data in the target file according to the line data mode so as to pointedly determine the length of each line of data according to different line data modes, determine the initial index of each line of data according to the length of each line of data, analyze the target file according to the initial index of each line of data by using the old version program, and further realize effective analysis of the newly defined binary file after gray scale upgrading by the old version program, the problems that the old version program cannot analyze the binary file and the analysis is wrong after the gray scale is upgraded are solved.
Fig. 2 is a functional block diagram of a binary file parsing apparatus based on gray scale upgrading according to a preferred embodiment of the present invention. The binary file parsing device 11 based on gray scale includes a configuration unit 110, a determination unit 111, and a parsing unit 112. A module/unit as referred to herein is a series of computer program segments stored in a memory that can be executed by a processor and that can perform a fixed function. In the present embodiment, the functions of the modules/units will be described in detail in the following embodiments.
The configuration unit 110 configures a file format of a binary file as a target format when performing a gray scale up.
The gray scale upgrading is a local upgrading mode, and adverse effects caused by upgraded program bug can be reduced to the greatest extent.
The traditional binary file does not support the gray scale upgrading, and when the program version is inconsistent with the file version, the situation of disordered analysis or program abnormity occurs.
Therefore, the present embodiment reconfigures the file format of the binary file, and uses the file as a new format of all the binary files after the gray scale upgrade.
Specifically, the configuring unit 110 configures a file format of the binary file as the target format, including:
configuring a first field for recording a message header size of the binary file;
configuring a second field for recording a line data mode of the binary file;
when the line data mode is a fixed line width mode, configuring a third field for recording the fixed line width of each line of data of the binary file, and adding the first field, the second field and the third field in a message header of the binary file; or
And when the line width mode is a non-fixed line width mode, adding the first field and the second field in a message header of the binary file, respectively configuring each fourth field for recording the line width of each line of data of the binary file, and correspondingly adding each fourth field at the initial position of a message body of each line of data of the binary file.
The fixed line width mode refers to that each line of data of the binary file has the same line width, that is, the length of each line of data is the same.
The non-fixed line width mode means that each line of data of the binary file does not have the same line width, that is, the length of each line of data is the same and also different.
In this embodiment, other fields may also be added to the message header of the binary file according to actual requirements. For example: a field representing a partition number (which may be adjusted according to actual traffic requirements) may be added, or a field representing a node name, or a field of signature information, etc. may be added.
Taking the line data mode as the fixed line width mode as an example, a fixed length (53 bytes) field is added as a message header, and then the first 53 bytes of the first message starting from the 54 th byte as the message header may respectively include the following fields:
[0,8) bytes (i.e., the first field): the first 8 bytes are used to define the header size, here 53;
[8,9) bytes (i.e., the second field): 1 byte is used to define a row data pattern;
[9,41) bytes: 32 bytes are used for defining signature information such as node names or file descriptions;
[41,49) bytes (i.e., the third field): 8 bytes are used to define the length of each line of data (from which old version programs can automatically calculate the starting index of the next line of messages);
[49,53) bytes: the last 4 bytes are used to define the total number of data lines of the binary file.
Taking the row data mode as the non-fixed row width mode as an example, the third field may be deleted from the message header in the above example, and a corresponding fourth field may be added at the beginning byte of each row of data in the message body. For example: the fourth field may be 4 bytes, representing the length of each row of data.
The length of each line of data in the binary file is determined by reconfiguring the file format of the binary file, so that the program of any new or old version can analyze the binary file according to the length of each line of data, and the problem of messy message bytes is avoided.
When detecting that the old version program receives an arbitrary binary file, the determination unit 111 determines the arbitrary binary file as a target file.
The arbitrary binary file may be a file redefined after the gray scale is upgraded, that is, a file with a newly added field at a suffix of each row of records. For such newly defined files, in the conventional parsing scheme, when the old version program parses the fields built in the program, the newly added field error is parsed into the starting byte of the next record, and actually, the newly added field is the last byte of the current record, which may result in a parsing error.
The arbitrary binary file may also be a file that is not redefined after the gray scale is upgraded, and at this time, the program of any new or old version may perform normal analysis on the arbitrary binary file.
The parsing unit 112 parses the message header of the target file according to the target format to obtain the line data pattern of the target file.
In this embodiment, the parsing unit 112 parses the message header of the target file according to the target format, and obtaining the line data pattern of the target file includes:
reading the second field from the message header of the target file according to the target format;
and determining the line data mode of the target file according to the data content of the second field.
Wherein the second field is defined in a header of the target file for representing a line data pattern of the target file.
Wherein the row data pattern may include, but is not limited to: fixed line width mode, non-fixed line width mode.
The determining unit 111 determines the length of each line of data in the target file according to the line data pattern.
In this embodiment, the determining unit 111 determines the length of each line of data in the target file according to the line data pattern, including:
when the line width mode is the fixed line width mode, reading the third field from the message header of the target file, and determining the length of each line of data in the target file according to the data content of the third field; or alternatively
And when the line data mode is the non-fixed line width mode, reading a fourth field of each line of data from the message body of the target file, and determining the length of each line of data in the target file according to the data content of the fourth field of each line of data.
That is, when the line data mode is the fixed line width mode, since each line of data has the same line width, the length of each line of data can be obtained by directly obtaining the data content of the corresponding field from the message header.
When the line data mode is the non-fixed line width mode, the length of each line of data may be different, so that the data content of the corresponding field of the message body of each line of data may be read to obtain the length of each line of data respectively.
The determining unit 111 determines a start index of each line of data according to the length of each line of data.
In this embodiment, the determining unit 111 determines the start index of each line of data according to the length of each line of data includes:
reading the first field from a message header of the target file;
determining the message header length of the target file according to the data content of the first field;
determining the initial position of the message body of the target file according to the length of the message header as the initial index of the first line data of the target file;
determining the length of the head line data according to the length of each line of data;
calculating the difference value between the length of the head line data and the length of the message header to obtain the length of the message body of the head line data;
determining the length of each line of data as the message body length of each line of data from the second line of data;
and splitting the message body according to the length of the message body of each line of data to obtain the initial index of each line of data.
For example: when the length of the message header is 50 bytes, starting from the 51 th byte of the first line data to be the initial index of the first line data of the target file, when the length of the first line data is determined to be 100 bytes, the length of the message body of the first line data is 100-50=50 bytes, at this time, the initial index of the second line data is 101 th byte, if the length of the second line data of the message body is determined to be 100, starting from the 101 st and 200 th bytes to be the message body of the second line data, the initial index of the third line data is 201 th byte, and so on, the initial index of each line of data is obtained.
The parsing unit 112 parses the target file according to the initial index of each line of data by using the old version program.
In this embodiment, the parsing unit 112 parsing the target file according to the start index of each line of data by using the old version program includes:
acquiring the length of an analyzable field of each line of data of the old version program;
for each line of data, when the analyzed field length of the old version program is detected to reach the corresponding analyzable field length, skipping the current line of data, and determining the next line of data of the current line of data according to the initial index of each line of data;
and continuing to analyze the target file from the next line of data.
It will be appreciated that the old version program will configure the parse-able field length for each row of data and parse the binary file according to the parse-able field length for each row of data.
For example: when the resolvable field length of each line of data of the old version program is 100 bytes, in the resolving process, if the current line of data has 200 bytes in total but the resolving field length of the current line of data reaches 100 bytes, the resolving of the current line of data is stopped, and the next line of data is directly jumped to continue resolving, so as to avoid invalid resolving, realize the compatibility of the old version program to the newly defined binary file, and avoid resolving errors.
Moreover, since fields which are not analyzed and skipped in each row of data are newly added fields, the fields cannot be processed by the old version program, so that even if the fields are not analyzed, the execution of the old version program is not affected, program errors are avoided, and the analysis efficiency is improved.
Moreover, the new version program has adaptability to the binary file newly defined after the gray scale is upgraded, so that the binary file format reconfigured by the embodiment can realize the up-down compatibility of the new version program and the old version program after the gray scale is upgraded, the flexibility and the adaptability of the gray scale upgrade are increased, and the new version program has a higher application prospect in the fields of stock exchange trade systems and the like.
It can be seen from the above technical solutions that, in performing gray scale upgrade, the present invention can configure a file format of a binary file as a target format to assist file parsing, when it is detected that an old version program receives any binary file, determine the any binary file as a target file, parse a message header of the target file according to the target format to obtain a line data pattern of the target file, determine a length of each line of data in the target file according to the line data pattern, so as to pointedly determine the length of each line of data according to different line data patterns, determine an initial index of each line of data according to the length of each line of data, parse the target file according to the initial index of each line of data by using the old version program, and further implement effective parsing of the new defined binary file after gray scale upgrade by the old version program, the problems that the old version program cannot analyze the binary file and the analysis is wrong after the gray scale is upgraded are solved.
