Description
Technical Field
The invention relates to the field of computer operating systems, in particular to a method for generating a smart television log.
Background
In the android intelligent television, software comprises a C layer (C \ C + +) and a Java layer, and the C layer software outputs logs in two ways:
firstly, outputting log information to standard output equipment (such as tty terminal) directly by adopting C standard information output (printf or cout);
and secondly, outputting the log information to a log information file (log.txt) of an android standard by adopting an android log system, and displaying the log information on a standard output device (tty terminal) through a logcat command.
Aiming at the first mode, in order to check the log, standard output equipment (development tools, such as a serial port) needs to be connected, and smart television software is operated at the same time; therefore, for the android smart television, the log information can be acquired only by connecting a debugging tool when the smart television software runs in the mode; aiming at the second mode, an android log system needs to be opened, and a log.txt log file is generated by the android log system; and a serial port debugging tool can be connected when the intelligent television software runs, and the corresponding file can be realized and output on the output equipment through the logcat command. Based on the difference between the two modes, for convenience, the second mode is usually adopted in the android smart television to perform log management and control.
The android smart television as an embedded system is restricted by various factors, the hardware configuration is limited, in order to improve the operation efficiency and speed of the system and improve the user experience, a strategy of closing logs (logs) is adopted in mass production products, if the log information management and control of the C-layer software adopts a second mode, the log information of the C-layer software in a release (mass production) product is closed at the same time, that is, there is no log information in the layer C software, if the problem caused by the layer C software occurs in such a release product, there is no log file, which causes inconvenience to the problem analysis and solution, in order to acquire the log file, the log system needs to be manually opened and the problem is reproduced, which wastes a lot of time, reduces the problem analysis and solving efficiency, particularly, for some accidental problems, the problems may not be reproduced, so that the problems cannot be solved; similarly, if the first mode is adopted to manage and control the C-layer software log, since the release product is basically used by the user, it cannot be guaranteed that standard output equipment outputs log files, and inconvenience is also caused to problem analysis and solution.
Therefore, the C-layer software of the smart tv release (mass production) in the conventional technology cannot automatically generate logs, and the problem analysis and solution are inconvenient when the problem caused by the C-layer software occurs.
Disclosure of Invention
The technical problem to be solved by the invention is as follows: the method for generating the intelligent television logs solves the problems that logs cannot be automatically generated by C-layer software of an intelligent television release version and are inconvenient to analyze and solve when problems caused by the C-layer software occur in the traditional technology.
The technical scheme adopted by the invention for solving the technical problems is as follows:
the intelligent television log generation method comprises the following steps:
a. adding a version attribute in an android system attribute of the smart television for distinguishing a system development version and a release version software;
b. classifying the C-layer software logs of the android system according to the log information categories, defining different log grades for log information of different categories, and simultaneously setting and storing the grades of the output logs of the C-layer software;
c. in the system development version, log management and control are carried out on C-layer software in a mode of directly outputting log information to standard output equipment or outputting the log information to a log information file of an android standard by using an android log system;
d. in the system release version, the C-level software outputs the log information of the specified level to a specified log file by using a C standard function snprint and an android file management technology.
As a further optimization, in step d, the outputting the log information of the designated level to the designated log file by using the C standard function snprint and the android file management technology specifically includes:
and converting the log information which accords with the preset output level into character strings by utilizing the snprint, writing the corresponding character strings into the tail of a specified log file in an additional mode, and outputting the log information in a file form.
In the scheme, in the system release version, the log information meeting the preset log output level is output in a file form, so that the log file of the C-layer software can be output as required, software developers can analyze and position related software problems in mass production products, the time for problem recurrence is saved, and the efficiency for solving the problems of mass production products is improved.
As a further optimization, step d further includes managing the log file: and deleting the log file when a certain condition threshold value is met.
In the scheme, in order to reduce the influence on the operating efficiency of the whole machine, when a certain condition threshold value is met, the log file is deleted.
As a further optimization, the certain threshold condition is:
when the intelligent television is started, if the time of detecting the log file exceeds the set time or the size of the log file exceeds the set byte, deleting the log file.
According to the scheme, the storage time of the log file and the size of the log file are used as judgment conditions for log file deletion management, and the log file can be deleted when the storage time exceeds the set time or the size of the log file exceeds the set byte, so that the operation efficiency of the whole machine is improved.
As a further optimization, the certain threshold condition is:
after the log file is automatically extracted, the log file is deleted.
According to the scheme, the extraction state of the log file is used as a judgment condition for log file deletion management, once the log file is extracted, the log file is indicated to be used for problem analysis, and the log file is deleted, so that the running efficiency of the whole machine is improved.
The invention has the beneficial effects that:
different processing is performed on the C-layer software on log management and control according to versions, namely different log output modes are adopted on development versions and release versions (mass production versions), so that log files can be automatically output in a file form on the release versions according to requirements, a log system does not need to be manually opened, and standard output equipment does not need to be connected; therefore, software developers can conveniently acquire log files of relevant information on the release version, problem analysis and positioning are carried out according to the log files, time for simulating and reproducing problems for many times due to the fact that the release version has no log files is shortened, and therefore efficiency of solving problems found in mass production versions is improved.

2) classifying the C-layer software logs according to log information categories (including error \ debugging \ common information and the like), defining different log levels for different types of log information, simultaneously setting the level of the C-layer output logs and storing the levels, and processing according to the set output level when the log information is output, namely filtering the log information, and outputting only the log information which accords with the set output level, thereby reducing the occupation of the storage resources of the system;
3) in the system development version, log management and control are carried out on C-layer software in a mode of directly outputting log information to standard output equipment or outputting the log information to a log information file of an android standard by using an android log system;
4) in a system release version, outputting specified-level log information to a specified file by using a C standard function snprint and an android file management technology for C-layer software, namely converting the log information into a character string by using the snprint and writing the corresponding character string into a specified log file tail in an additional mode to realize the output of the log information in a file form;
in addition, in order to reduce the influence on the running efficiency of the whole machine, the log file of the software of the C layer of the release version is deleted and managed according to specific conditions, and the specific management mode is that when the existing time of the log file exceeds the set time or the size of the log file exceeds the set size, the log file is deleted when the machine is started; or after automatically extracting the log file, deleting the log file.

3. if the current system version is the release version, outputting the log information meeting the conditions to a specified log file according to the flow in the figure 3;
4. the system also manages the existing log files correspondingly:
when the existing time of the log file exceeds the set time or the size of the log file exceeds the set size, deleting the log file when starting the computer; or after automatically extracting the log file, deleting the log file.
As shown in fig. 3, the log output flow for the release version of the C-layer software includes:
firstly, judging whether the log information to be output meets the output condition, namely whether the log grade meets the preset output grade requirement, opening a log file in a mode of adding information to the tail of the file for the log information meeting the set output grade, then converting the log information into a character string according to a specified format by using a snprint, writing the character string into the tail of the log file by using a write operation function, and finally closing the log file, thereby finishing the output of the log information of the specified grade.
