It will be appreciated by those skilled in the art that without certain details, the disclosure equally be can be implemented.In some instances, for
Method, means, element and circuit well known to those skilled in the art are not described in detail, in order to highlight the purport of the disclosure.
Embodiment 1
Fig. 1 is a kind of flow chart of resource transfer analysis method shown according to an exemplary embodiment.This method can answer
For in terminal device (such as smart phone) or server.As shown in Figure 1, being analyzed according to the resource transfer of the embodiment of the present disclosure
Method includes:
Step S11 obtains the call operation for being directed to resource；
Step S12 judges whether the call operation meets analysis item in the case where getting the call operation
Part；
Step S13 is analyzed and is recorded and the call operation phase in the case where the call operation meets analysis condition
Corresponding recalls information；
Step S14 exports recorded recalls information in the case where meeting information output condition.
The call operation for resource can be obtained in accordance with an embodiment of the present disclosure, analyze and record and meet analysis condition
The corresponding recalls information of call operation, and recorded recalls information is exported, thus efficiently and accurately analysis system resource
Calling situation.
For example, in the operating system of terminal device, application program App needs calling system resource (example when running
Such as memory headroom), such as application system resource is needed when starting operation, terminate to need free system resources when operation, these mistakes
The application programming interface API in calling system library is needed in journey.It is available for resource in the resource transfer analysis
Call operation, such as in Android system, Android local layer identification code (Android can be kidnapped by way of symbol abduction
Native code) to the library libc provide API call operation, to obtain the call operation.Tool of the disclosure to call operation
Body acquisition modes are with no restrictions.
In one possible implementation, when getting call operation, it is understood that there may be acquired call operation is not
The case where being call operation to be analyzed, for example, self kidnapping for often will appear in symbol abduction mode (has kidnapped symbol misfortune
Hold the resource transfer operation of operation itself), so as to cause the result inaccuracy of resource transfer analysis.Thus, in order to avoid this
Situation occurs, it can be determined that whether acquired call operation meets analysis condition.If being unsatisfactory for analysis condition, do not analyze
The call operation continues to obtain；If meeting analysis condition, the call operation is analyzed, and will be corresponding with the call operation
Recalls information be recorded in the memory headroom of system, such as record in a manner of mapping call stack in recalls information, resource
Descriptor etc..
In one possible implementation, if meeting information output condition, such as reach preset actual conditions
(app end of run etc.) or user have input information output order, then export recorded recalls information.It can be for example from upper
Recorded recalls information is obtained in the system memory space stated, and readable file such as journal file is converted into, for user
It checks and/or is further processed.
Fig. 2 is a kind of flow chart of resource transfer analysis method shown according to an exemplary embodiment.As shown in Fig. 2,
In one possible implementation, step S11 includes:
Step S111 kidnaps the call operation for being directed to application programming interface API.
For example, local layer identification code apply or discharge resource when can calling system library provide API, can using with
Third party's tool valgrind similar mode kidnaps the API that local layer identification code provides system library by way of symbol abduction
Call operation, to obtain the call operation.For example, can establish the independent library so in Android system
Libleaktest.so does not do any change to the source code of tested App.It is preferential to load in app starting to be tested
To memory, the symbol that LD_PRELOAD type can be used kidnaps mode and kidnaps Android local layer identification code in the library libleaktest.so
To the call operation for the API that the library libc provides.Also other kinds of symbol abduction mode can be used and kidnap call operation, this public affairs
It opens to this with no restriction.
In this way, can be in the case where not changing the source code of tested App, the calling kidnapped for API is grasped
Make, improves the acquisition efficiency of call operation.
Fig. 3 is a kind of flow chart of resource transfer analysis method shown according to an exemplary embodiment.As shown in figure 3,
In one possible implementation, the method also includes:
Step 15, corresponding with the call operation obtained thread identification is stored, and in the first memory space with the
Thread identification corresponding with the call operation currently carried out is marked in one label.
For example, the first memory space, first memory space can be created when the library libleaktest.so starts
It can be static bitmap (bitmap), be also possible to the memory space of other storage forms.It, can when obtaining call operation every time
It is stored in first memory space with the thread identification (such as Thread Id) of the corresponding thread of the call operation that will acquire, and
The thread is marked, such as labeled as 1 (the first label).For example, position can be used when first memory space includes bitmap
The value of each in figure indicates whether the corresponding thread of thread identification is doing the operation of corresponding API Calls, and ongoing
The corresponding thread of call operation can be expressed as 1 in bitmap, and the thread for not being called operation currently can be in bitmap
It is expressed as 0 (the second label).Correspondingly, at the end of the call operation currently carried out, can identify respective thread first is marked
Note is changed to the second label, such as becomes 0 by 1.
In this way, the thread for being called operation can be marked, avoid the occurrence of repetition obtain or
Obtain the case where omitting.
Fig. 4 is a kind of flow chart of resource transfer analysis method shown according to an exemplary embodiment.As shown in figure 4,
In one possible implementation, step 12 includes:
Step 121, whether inquire in first memory space has, label corresponding with the call operation currently obtained
For the thread identification of the first label；
Step 122, do not have in first memory space it is corresponding with the call operation currently obtained, labeled as institute
In the case where the thread identification for stating the first label, judge that the call operation meets analysis condition.
For example, when getting call operation, it is understood that there may be acquired call operation is not calling to be analyzed
The case where operation, for example, self kidnapping for often will appear in symbol abduction mode (has kidnapped the money that symbol kidnaps operation itself
Source call operation), so as to cause the result inaccuracy of resource transfer analysis.Therefore, it is possible to judge whether the call operation is full
Sufficient analysis condition.
In order to avoid repeating to obtain (such as self kidnapping), the relevant technologies generally use the call operation addition mark to acquisition
The mode of will is no longer kidnapped if flag bit is true after coming in next time for example, mark is set to true after kidnapping.But the party
Case, which will lead to, misses some calling that should be kidnapped, for example asynchronous the entering of multiple threads is kidnapped, if a thread is mark
Will is set to true, then the calling that should be kidnapped of other threads will not be held as a hostage, and causes to obtain and omit.
In one possible implementation, as previously mentioned, storage can be created when the library libleaktest.so starts
There is the first memory space of thread identification corresponding with the call operation obtained, and to the thread for being called operation
It is marked with the first label (such as 1).When getting call operation and for example kidnapping to correlation API, inquiry the first storage sky
Between in whether have it is corresponding with the call operation currently obtained and labeled as first label thread identification ID, for example, bitmap
In the corresponding position of the thread identification value be 1, if so, then illustrate the call operation currently obtained for repeat obtain, the tune
Leaktest.so itself is come from operation, it should directly be let pass, without analysis；If without the call operation currently obtained
Thread Id corresponding, labeled as the first label, then illustrate the call operation currently obtained from local layer identification code
(native code), meets analysis condition, is analyzed.If should there is no what is currently obtained in the first memory space
The corresponding thread identification ID of call operation, then be considered as and be unsatisfactory for analysis condition, and thread identification ID can be added to first
In memory space and it is labeled as first identifier, the calling in the subsequent library leaktest.so itself is prevented also to be held as a hostage.Meet analysis
When condition, the call operation currently obtained can be analyzed and be recorded, it, can be by the tune after completing analysis and record
The second label is changed to by the first label with corresponding thread identification is operated, such as becomes 0 from 1.
In this way, it can be omitted to avoid repeating to obtain or obtain, improve the accurate of the calling analysis of system resource
Property.
Fig. 5 is a kind of flow chart of the step 13 of resource transfer analysis method shown according to an exemplary embodiment.Such as
Shown in Fig. 5, in one possible implementation, step 13 includes:
Step S131 is stored in the second memory space in the case where the call operation is to apply for the calling of resource
Recalls information corresponding with the call operation；
Step S133, in the case where the call operation is to discharge the calling of resource, from second memory space
Delete recalls information corresponding with the call operation.
For example, when call operation meets analysis condition, it can analyze the type of the call operation and handled.
If the call operation is to apply for the calling (such as malloc, socket in the API of Android system etc.) of the API of resource,
The corresponding recalls information of the call operation can be saved in the second memory space.The recalls information may include the tune
With the corresponding Thread Id of the API of operation, call stack, resource descriptor etc.；Second memory space can be resource descriptor
For keyword (pointer address), call stack is the Hash mapping (map) for being worth (content).
In one possible implementation, if the call operation is API Calls (such as the Android system for discharging resource
API in free, close etc.), then can be searched in the second memory space and delete calling corresponding with call operation
Information, for example, search corresponding with call operation resource descriptor, and by the key-value pair found (keyword and value) from mapping
Middle deletion.
In one possible implementation, it should be noted that above-mentioned analysis record operation can be independent
It is carried out in such as libleaktest.so of library, does not need to do the source code of tested App any change.In such as Android system
In API, obtain (symbol abduction) to call operation relate generally to malloc, calloc, free, fopen, fclose,
The libraries such as socket, eventpoll, close, pthread_create, pthread_detach, pthread_join.
In this way, the calling of application resource can be stored in the second memory space and deletes the tune of release resource
With, efficiently and accurately record system resource calling situation.
Fig. 6 is a kind of flow chart of the step 14 of resource transfer analysis method shown according to an exemplary embodiment.Such as
Shown in Fig. 6, in one possible implementation, step 14 includes:
Step 141, monitor whether that there are recalls information output orders；
Step 142, there are recalls information output order, it is judged as and meets information output condition；
Step 143, it in the case where meeting information output condition, reads and exports from second memory space and deposited
The recalls information of storage.
For example, in the case where having recorded recalls information, recorded recalls information can be exported.But some
In system, recorded recalls information can not be exported in real time in a manner readable, such as in Android system, Android
The API for obtaining call stack, including unwind_backtrace and get_backtrace_ are provided in the library libcorkscrew
symbols.The wherein pointer address of the available current call stack of unwind_bakctrace, get_backtrace_
Symbols passes through the mapping map file of acquisition process and maps pointer address, is converted into readable call stack.
But found during actual use, get_backtrace_symbols executes very slowly, if robbed every time
All call get_backtrace_symbols that can seriously affect the App speed of service after holding.Therefore, it is possible in the second memory space
It is middle to store recalls information corresponding with the call operation, by the way of Delay Mapping (backtrace), that is, needing
Pointer address (such as keyword) is mapped to readable text again when exporting analysis log.
In one possible implementation, can start automatically at load (such as load library libleaktest.so)
Listening thread monitors the order line terminal (such as terminal module of smart phone) of terminal device with the presence or absence of recalls information
Output order, wherein the recalls information output order can be expressed as "/sdcard/LeakTest/dr ".The listening thread can
It whether there is with continuing to monitor such as "/sdcard/LeakTest/dr " file, if there is no this document, then can continue to supervise
It surveys；If there is this document, then may determine that meet information output condition.
It in one possible implementation, can be from second storage in the case where meeting information output condition
It is read in space and exports stored recalls information.It, can be by calling journal output module will such as in Android system
Testing result (recalls information stored) in second memory space (mapping) is output to log logcat, and user can pass through
Filter the testing result that LeakTest keyword captures memory overflow from logcat buffering.It can also be using other modes by the
The recalls information that two memory spaces are stored is read and exports as readable text, and the disclosure is not limited this.
In one possible implementation, when carrying out resource transfer analysis to Android system, since Android is special
Process flowchart mechanism, the analysis of local (Native) global data, which reaches function, when exiting App to be called, this leads to not
Realization exports examining report when App is exited automatically, this is also that current valgrind tool cannot be efficiently applied to Android
The major reason of operation.And the process of memory leak detecting sometimes itself need not and exit app, only detect one or
For multiple scenes either with or without RAM leakage, this requires us can control output test result at any time.Therefore, using the defeated of the disclosure
Mode out, the control that log exports can be converted to user it is right/control of sdcard/LeakTest/dr file, when user runs
Complete test analysis step, as long as by executing touch/sdcard/LeakTest/dr in terminal when wanting to check testing result
The output of result, the control of very convenient user can be realized.
Following present a kind of possible application scenarios of the resource transfer analysis method of the disclosure.For Android local layer
Code (Android native code), can establish the independent library so libleaktest.so.It is treated in Android terminal
App is surveyed to be configured, such as: setprop wrap.packet.name " LD_PRELOAD=/path/to/
leaktest.so".Then, start App to be tested to be tested.It is preferential to load in App to be tested starting
Mode is kidnapped using the symbol of LD_PRELOAD type and kidnaps Android local layer identification code pair to memory in the library libleaktest.so
The call operation for the API that the library libc provides, being stored as resource descriptor is keyword, and call stack is the Hash mapping (map) of value.
When needing to export result, touch/sdcard/LeakTest/dr order is executed in Android terminal.Then, pass through
Logcat obtains log: logcat | grep LeakTest.
In this way, stored recalls information can be exported when meeting information output condition, improve output
Convenience and accuracy.
According to the resource transfer analysis method of the disclosure can the calling situation rapidly and accurately to system resource divide
Analysis, and do not need to do any change to detected source code；Compared with existing memory testing tool, when significantly reducing load
Between, runing time and rate of false alarm；The memory overflow of Android operation system Native code can easily be analyzed, thread is let out
The problems such as dew, has ensured the product quality of android system.
