Description

Technical Field

[0002] In order to solve problems that are difficult to reproduce and track abnormal problems encountered in network requests, the mobile terminal needs to record network interface request logs, key operation logs, and crash logs. Mobile terminals often use Java to implement logging. Frequent I / O operations will affect the performance of the mobile terminal, especially when used on industrial PDAs with relatively poor performance. It often causes user operations to freeze. In severe cases, the phone will display ANR (Application Not Response). In addition, the reasons for mobile terminal freezes may also include: no limit on the cache file size, no compression of recorded logs, slow reading and writing processes, etc. Therefore, how to improve the fluency of mobile terminal logging to avoid the occurrence of the above problems is a technical problem that needs to be solved urgently. Summary of the invention

[0004] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a mobile terminal log data management method, system, device and medium to solve the technical problems in the prior art of mobile terminal freezes caused by the need to record logs and improper control of log cache file size leading to ANR during the use of the mobile terminal.

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. Although certain embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be interpreted as being limited to the embodiments described herein. On the contrary, these embodiments are provided to provide a more thorough and complete understanding of the present invention. It should be understood that the drawings and embodiments of the present invention are only for exemplary purposes and are not intended to limit the scope of protection of the present invention.

[0028] It should be understood that the various steps described in the method embodiments of the present invention may be performed in different orders and / or in parallel. In addition, the method embodiments may include additional steps and / or omit the steps shown. The scope of the present invention is not limited in this respect.

[0029] The term "including" and its variations used in this document are open inclusions, that is, "including but not limited to". The term "based on" means "based at least in part on". The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one other embodiment"; the term "some embodiments" means "at least some embodiments"; the term "optionally" means "optional embodiments". Relevant definitions of other terms will be given in the following description. It should be noted that the concepts of "first", "second", etc. mentioned in the present invention are only used to distinguish different devices, modules or units, and are not used to limit the order or interdependence of the functions performed by these devices, modules or units.

[0030] It should be noted that the modifications of "one" and "plurality" mentioned in the present invention are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise clearly indicated in the context, it should be understood as "one or more".

[0031] like Figure 1 As shown, an embodiment of the present invention provides a mobile terminal log data management method, the steps comprising:

[0032] S1. Dynamically calculate the maximum value R of the available cache space of the log file based on the current available memory of the mobile terminal.

[0033] S2. Create N cache spaces that are consistent with the number of cores on the mobile terminal. The maximum amount of space that can be used by each cache space is R / N.

[0034] S3, write the log into the cache space currently in use and calculate the character size of the cache to be written and the available amount of the cache space; if the character size to be written is larger than the available amount of the cache space, put the cache data in the cache space into the cache management and jump to step S4; if the character size to be written is smaller than the available amount of the cache space, write it directly.

[0035] S4. Check whether the available amount of cache space needs to be released. If it needs to be released, call the entryRemoved method and customize the operation to compress the data in the cache management and then write it to the disk, and clear all cache space in the cache management.

[0036] Specifically, the code is as follows:

[0037]

[0038]

[0039] Of course, if there is no need to release space in step S4, the current cache space is directly stored therein; if it needs to be released, all cache spaces in the cache management, the data currently to be written, and the cache space currently in use are written together into the SD card.

[0040] It should be noted that in step S2, after the space allocation is completed, all cache space is reclaimed. At the same time, the compression strategy used in this scheme first uses phrase compression to remove repeated phrases in the text, and then uses LZ77 to further compress the remaining data to obtain a better compression effect. Then it is written to the disk.

[0041] This technical solution uses mmap to write to disk. Binder only needs one data copy in cross-process communication, which is one less data copy process than traditional cross-process communication methods such as Socket and pipe.

[0042] The present application also provides a mobile terminal log data management system, which includes:

[0043] A calculation unit, used to dynamically calculate the maximum value R of the available cache of the log file according to the current available memory of the mobile terminal;

[0044] The allocation unit is used to create N cache spaces that are consistent with the number of cores on the mobile terminal. The maximum amount of space that can be used by each cache space is R / N.

[0045] The cache unit is used to write the log into the cache space currently in use and calculate the character size of the cache to be written and the available amount of the cache space; if the character size to be written is larger than the available amount of the cache space, the cache data in the cache space is put into the cache management; if the character size to be written is smaller than the available amount of the cache space, it is directly written;

[0046] The release unit is used to detect whether the available amount of the cache space needs to be released. If it needs to be released, the entryRemoved method is called and the custom operation is to compress the data in the cache management and then write it to the disk, and clear all cache space in the cache management.

[0047] In particular, the calculation unit calculates in real time and influences the allocation unit to adjust in real time the maximum value of the space available for each cache space; the allocation unit is also used to reclaim all cache spaces after the space allocation is completed.

[0048] In particular, the system also includes: a compression unit for first removing repeated phrases in the text using phrase compression, and then further compressing the remaining data using LZ77; a writing unit for writing the compressed data processed by the compression unit to the disk through mmap.

[0049] The technical effect that can be achieved by this embodiment is basically the same as the technical effect that can be achieved by the aforementioned comprehensive evaluation method of production activities based on multi-dimensional indicators, and will not be repeated here.
