Embodiment, belong to the scope of the present invention.
In order that those skilled in the art more fully understand the present invention program, with reference to the accompanying drawings and detailed description
The present invention is described in further detail.
Next, a kind of method for embedded system log recording that the embodiment of the present invention is provided is discussed in detail.Fig. 1 is
A kind of flow chart of the method for embedded system log recording provided in an embodiment of the present invention, this method include：
S10：Receive the total number of files value of user's setting and the higher limit of file size；
In embodiments of the present invention, can determine to need to draw internal memory according to the memory size for distributing to daily record (log)
It is divided into how many individual files and carrys out log.
Firstly the need of the size (being assumed to be S) for the internal memory for confirming to distribute to log, according to the size of storage allocation come the determination date
Will rolls the strategy of record, and after log memory size is distributed in confirmation, by internal memory N deciles, N is the total value set.N
Specific value value can be considered according to the internal memory for distributing to log.
In embodiments of the present invention, the storage location of log information can be pre-set, for example, can pre-set
, then can be by log information recording to this document when there is new log information generation for storing the filename of log information
In file corresponding to name.Introduced conveniently to be follow-up, can will be referred to as target text for storing the journal file of current log information
Part.
Higher limit can be the maximum of file destination memory size.Using the size of log internal memory as S, by internal memory N deciles
Exemplified by, according to principle of equipartition, accordingly, each file size for being used to store log information is S/N.To avoid the occurrence of target text
The remaining memory space of part can not store log information to be stored completely, therefore, can be by the upper limit when setting higher limit
The slightly smaller than S/N that value is set.
S11：When needing log information, file destination is judged whether.
When system needs the log information into log, if first record log information, then perform
S16 creates file destination (log files), due to being to create file destination for the first time, so the text in the absence of log information
Part number, which transfinites, exceedes total value, or current file destination size transfinites the problem of exceeding higher limit, therefore
After creating file destination, log information can be write into the file destination to perform S17；If not first record daily record
Information, then file destination existed, therefore, to file destination write log information before, it is necessary to first to current target
The problem of whether file size transfinites is judged to perform S12.
S12：Judge whether the size of the file destination exceedes the higher limit.
When the memory size of file destination is more than the higher limit, then memory headroom workable for illustrating the file destination is
Through very little, be not suitable for storing new log information again, can now perform S13；When file destination memory size not less than
During the higher limit, then illustrate that the file destination can still continue to store new log information and perform S17.
S13：The number of all journal files for log information created is counted, judges whether the number is big
In equal to the total value.
When the size of file destination exceedes higher limit, continue the new caused log information of storage for the ease of follow-up,
In the embodiment of the present invention, the file destination renaming that will can transfinite, a mesh named with old file name is then re-established
File is marked, for storing log information.
For example, the file destination created is log files, the entitled runtime.log of its file, when the size of the file destination
When reaching higher limit, by log file RNTO * .1, the i.e. runtime.log.1, then using original name
Runtime.log re-creates log files, to the file destination newly created in continue to write to log information.
But because the memory size for distributing to log information is limited, accordingly, the number of the journal file of foundation
A total value corresponding to having, after the number of all journal files of establishment reaches total value, because memory size is limited, then
File destination can not newly be created.Therefore, when the size of file destination exceedes higher limit, then need first to judge all days created
Whether the number of will file exceedes the total value of setting.
When the number of journal file is more than or equal to the total value of setting, the journal file for illustrating to create has reached
Limit value, file destination can not be newly created again, can now perform S14；When the number of journal file is less than the total value of setting,
Illustrate can also continue to newly to create file destination, then perform S15.
S14：A journal file for not meeting preparatory condition is deleted, will be remaining according to the naming rule pre-set
Each journal file and the file destination renaming, and perform S16.
In embodiments of the present invention, a minimum journal file of reference value can be deleted.Specifically, can foundation
The time length of log information in journal file, ascending order arrangement is carried out to the journal file, after ascending order is arranged most
The latter journal file is deleted；Also will the journal file deletion of time at most.
In embodiments of the present invention, can using numeral as filename suffix, specifically, can be according to file name suffix
Increase 1 mode, renaming is carried out for remaining each journal file and the file destination.
So that total value is N as an example, when log files (runtime.log) size of establishment reaches higher limit, and bear the same name
When journal file has * .N-1 (runtime.log.N-1), * .N-1 (runtime.log.N-1) journal file is deleted,
Then by * .N-2 (runtime.log.N-2) file RNTO * .N-1 (runtime.log.N-1) of renaming before, according to
It is secondary to analogize, by * .1 (runtime.log.1) file RNTO * .2 (runtime.log.2) of renaming before, will before
Log files (runtime.log) the RNTO * .1 (runtime.log.1) newly created, it is newly-built log texts then to perform S16
Part (runtime.log) continues to write log information inside.
S15：According to the naming rule that pre-sets, by each journal file and the file destination renaming,
And perform S16.
The mode of file renaming is similar with the mode of file renaming in S14 in S15, will not be repeated here.
S16：Create file destination.
S17：The log information is write to the file destination, and returns to the S12.
Judged to return, it is necessary to whether transfinite to the size of file destination after log information writes file destination
S12.Aforesaid operations step is performed by circulating, log information can be recorded in a rolling manner.
The total number of files value of user's setting and the higher limit of file size are received it can be seen from above-mentioned technical proposal；Will
Caused log information storage, if the file destination is not present, needs first to establish the file destination into file destination；Its
In, the file destination has its corresponding filename, when the memory size of file destination exceedes higher limit, then by the file destination
Renaming, a file destination named with file name is then re-established, it is new that newly-built file destination can be used for record
Caused log information.Until the number of all journal files (including the file destination of foundation) of foundation exceedes total value
When, then a journal file for not meeting preparatory condition is deleted, will be remaining each described according to the naming rule pre-set
Journal file and the file destination renaming, and re-create file destination.The log by way of rolling, that is, work as
When log recording is reached for the internal memory higher limit of daily record distribution, the daily record of new record can cover oldest daily record, be carried so as to reach
High memory usage, extend the purpose of log recording time.
With reference to it is above-mentioned using numeral as the suffix of filename exemplified by, when system receive user input extraction instruct after,
The daily record that all journal files and the file destination record can then be believed in the way of file name suffix descending
Breath is merged into a file, so as to form complete log information；And the complete log information is uploaded to what is specified
Storage location.
Exemplified by using runtime.log as the filename of file destination, when needing to extract log, it is only necessary to according to
Order (the runtime.log.N-1 of Rename file suffix descending<<runtime.log.N-2…<<Runtime.log) will
Then log Piece file mergences upload to the storage location that user specifies into a file.
