It will be understood by those skilled in the art that the present disclosure may be practiced without some of these specific details. In some instances, methods, means, elements and circuits that are well known to those skilled in the art have not been described in detail so as not to obscure the present disclosure.

Example 1

Fig. 1 is a flowchart illustrating a method for determining a running time of a function itself according to an embodiment of the present disclosure, which may be applied to a terminal device and a server. As shown in fig. 1, the method may include:

step 101, creating an index file according to a log file of a program, wherein the index file comprises record position identifiers recorded correspondingly to each function in the log file of the program and call relations among the functions, and the records are used for recording information for executing function call of the program.

For example, the index file may be a file generated according to an entry and exit sequence of records corresponding to each function in a log file corresponding to a program, where record types in the log file may include an entry record and an exit record, the entry record may be used to record information that the program executes an entry function call, the exit record may be used to record information that the program executes an exit function call, the entry record may be used to record a time (also referred to as an entry call time) of the entry function call, and the exit record may be used to record a time (also referred to as an exit call time) of the exit function call.

For example, a log file of a program may be obtained, and an index file may be generated according to a recording position recorded by each function in the log file, where the index file may include a recording position identifier recorded by each function in the log file of the program and a call relationship between each function, and the recording position identifier may be used to identify a recording position recorded by the function in the log file. For example, the record position of the record (in-record and out-record) corresponding to each function in the log file may be identified by a position sequence number, or the record position of the record corresponding to each function in the log file may be identified by a byte number. The record position identifier in the embodiment of the present disclosure is not specifically limited, and may be identification information that can be used to identify the record position of the record (entry record and exit record) corresponding to each function in the log file.

For example: taking the example of identifying the recording position of the record (entry record and exit record) corresponding to each function in the log file by the position sequence number, assuming that the function a calls the function b and the function b calls the function c, the position sequence number corresponding to the entry record and the exit record of each function in the log file may be: entry for function a: 1. entry of function b: 2. logging of function c: 3. output record of function c: 4. output of function b records: 5. output record of function a: 6. the index file can record a function a: (corresponding record position identification (entry record: 1, exit record: 6), call relation: function b), function b: (corresponding record location identification (entry record: 2, exit record: 5), call relation: function c), function c: (corresponding record position identification (record in: 3, record out: 4) and call relation: none).

102, determining a first function and a recording position identifier of a corresponding record of a sub-function of the first function in the log file from the index file according to the recording position identifier and the calling relation;

for example, the record location identification of the first function and the sub-function called by the first function in the log file may be determined from the index file, such as: the method includes the steps of obtaining a first recording position identification corresponding to a first recording position of a first record of a first function in a log file from an index file, obtaining a calling relation of the first function from the index file, determining a second recording position identification corresponding to a second recording position of a second record of a sub-function called by the first function in the log file when the sub-function called by the first function exists, and determining that the second recording position identification of the sub-function called by the first function is empty when the sub-function called by the first function does not exist.

The first record may be a corresponding record of the first function in a log file corresponding to the program, and may include an entry record and an exit record of the first function, and the record location identifier corresponding to a record location (i.e., a first record location) of the first record of the first function in the log file corresponding to the program may be acquired from the index file, and the record location identifier may include a record location identifier corresponding to the entry record in the log file and a record location identifier corresponding to the exit record in the log file. Similarly, the second record is a corresponding record of the sub-function called by the first function in the log file corresponding to the program, and includes an entry record and an exit record of the sub-function called by the first function.

Step 103, acquiring the first function and the corresponding record of the sub-function of the first function from the log file according to the record position identifier of the corresponding record of the first function and the sub-function of the first function in the log file.

For example, after obtaining a first record position identifier of a first record of the first function and a second record position identifier of a second record of the sub-function of the first function, the first record of the first function may be obtained from a first record position identified by the first record position identifier in a log file corresponding to the program, and the second record of the sub-function of the first function may be obtained from a second record position identified by the second record position identifier in the log file corresponding to the program. For example: and acquiring the entry record of the first function from the log file according to the position sequence number corresponding to the entry record of the first function, and acquiring the exit record of the first function from the log file according to the position sequence number corresponding to the exit record of the first function.

And 104, determining the self running time of the first function according to the corresponding records of the first function and the subfunction of the first function.

For example, the running time of the first function may be determined according to the time information recorded in the first record of the first function, and for example, the running time of the first function may be determined according to the time information recorded in the outgoing record and the time information recorded in the incoming record of the first function. For example: the difference between the time information recorded in the outgoing record and the time information recorded in the incoming record of the first function may be determined as the running time of the first function. Similarly, the run time of the sub-function of the first function may be determined from the time information recorded in the second record of the sub-function of the first function.

The self-running time of the first function can be determined according to the running time of the first function and the running time of the second function. For example: determining the self running time of the first function as the difference value of the running time of the first function and the running time of the called sub-function. When the first function does not call any function, the running time of the first function is the self running time of the first function.

In this way, the index file created according to the log file includes the record position identifiers of the records corresponding to the functions in the log file of the program and the call relations among the functions, so that the record position identifiers of the first function and the sub-functions of the first function, which are recorded in the log file, can be obtained from the index file, the corresponding records of the first function and the sub-functions of the first function are obtained from the log file according to the record position identifiers, and the self-running time of the first function is determined according to the time information recorded in the corresponding records of the first function and the sub-functions of the first function. Therefore, according to the method for determining the self-running time of the function provided by the embodiment of the disclosure, compared with the method for obtaining and recording each record of each function by traversing a complete log file in the related art, the method can quickly locate the record positions of the first function and the corresponding record of the sub-function of the first function in the log file according to the record position identification, and further directly obtain the corresponding record of the first function and the sub-function of the first function from the log file, so that the time overhead and the memory overhead can be reduced, and the efficiency for determining the self-running time of the function can be improved.

FIG. 2 illustrates a flow diagram of a method of determining the runtime of a function itself, according to one embodiment of the present disclosure.

In a possible implementation manner, in step 102, determining, from the index file, a record location identifier of a corresponding record of the first function and the sub-function of the first function in the log file according to the record location identifier and the call relationship may include:

step 1021, determining a first record position identifier of a first record of a first function in the log file;

and 1022, determining a second record position identifier of a second record of a second function in the log file according to the call relation, wherein the second function is a sub-call of the first function.

For example, a first record location identification corresponding to a first record location of a first record of a first function in a log file may be determined from an index file, such as: and determining a recording position identifier corresponding to the recording position of the input record of the first function in the log file from the index file, and determining a recording position identifier corresponding to the recording position of the output record of the first function in the log file.

The call relation of a first function may be determined from the index file, where the first function calls a second function (for example, the entry and record location identifier of the first function in the index file corresponds to the entry and record location identifier of the first function, and the entry and record location identifier of the second function may correspond to the entry and record location identifier of the first function). The second record is a related record of the second function in a log file corresponding to the program, and may include an entry record and an exit record of the second function. A second record position identifier corresponding to a second record position of a second record of the second function in the log file corresponding to the program may be obtained from the index file), and the record position identifier may include a record position identifier corresponding to an incoming record of the second function and a record position identifier corresponding to an outgoing record of the second function.

In a possible implementation manner, the determining, in step 104, the self-running time of the first function according to the corresponding records of the first function and the sub-function of the first function may include:

the first record of the first function is a record corresponding to the first record position in the log file, and the second record of the second function is a record corresponding to the second record position in the log file.

For example, after determining a first record position identifier of a first record of a first function and a second record position identifier of a second record of a second function, a first record of the first function may be obtained from a first record position corresponding to the first record position identifier in a log file corresponding to the program, and a second record of the second function may be obtained from a second record position corresponding to the second record position identifier in the log file. For example: the method comprises the steps of obtaining an entry record of a first function from a log file according to a record position identification corresponding to the entry record of the first function, obtaining an exit record of the first function from the log file according to a record position identification corresponding to the exit record of the first function, obtaining an entry record of a second function from the log file according to a record position identification corresponding to the entry record of the second function, and obtaining an exit record of the second function from the log file according to a record position identification corresponding to the exit record of the second function.

For example, the running time of the second function may be determined according to the time information recorded in the outgoing record and the time information recorded in the incoming record of the second function. For example: the difference between the time information recorded in the outgoing record and the time information recorded in the incoming record of the second function may be determined as the running time of the second function.

After determining the runtime of the second function, since the second function is a sub-call of the first function, the self runtime of the first function may be a difference between the runtime of the first function and the runtime of the second function.

For example, the running time of the first function may be determined according to the time information recorded in the outgoing record and the time information recorded in the incoming record of the first function. For example: the difference between the time information recorded in the outgoing record and the time information recorded in the incoming record of the first function may be determined as the running time of the first function. The difference between the running time of the first function and the running time of the second function can be determined as the self running time of the first function.

When the first function does not call the second function, that is, the second function is empty, the running time of the second function may be determined to be 0, that is, the running time of the first function itself may be determined to be the running time of the first function.

For example, the record type in the log file may include an entry record and an exit record, the entry record may be used to record information that the program executes the entry function call, the exit record may be used to record information that the program executes the exit function call, and the position sequence numbers of the records in the log file may sequentially change according to the sequence of the generation of the records (for example, the position sequence numbers of the records in the log file sequentially increase or decrease according to the sequence of the generation of the records). The location of the record in the log file may be identified based on the location number of the record.

The index file can be generated according to the log file, in the index file, the position serial number of each record can correspond to one index number, the index number corresponding to the position serial number of the incoming record corresponds to the position serial number of the outgoing record of the incoming record, that is, the index number corresponding to the position serial number of each incoming record can be the same as the position serial number of the outgoing record corresponding to the incoming record; the index number corresponding to the position sequence number of the outgoing record corresponds to the position sequence number of the incoming record where the parent call of the function in the outgoing record is located, that is, the index number corresponding to the position sequence number of each outgoing record can be the same as the position sequence number of the incoming record where the parent call of the function in the outgoing record is located. For example, if a program includes a function a, a function b, and a function c, and the function a call calls the function b call and the function c call, respectively, then the log file of the program may be, for example, as shown in table 1:

TABLE 1

Position number	Record categories	Recorded content
			0	Go to record	Program execution enter function a call
1	Enter record	Program execution enter function b call
			2	Go out of record	Program execution exit function b call
3	Go to record	Program execution enter function c call
			4	Go out of record	Program execution exit function c call
5	Go out of record	Program execution exit function a call

The index file of the log file of the program may be, for example, as shown in table 2:

TABLE 2

Position number	Index number
		0	5
1	2
		2	0
3	4
		4	0
5	-1

The index number of a function without a parent call can be set to a special character, for example: in table 2, since the function a call has no parent call, the index number corresponding to the position sequence number of the record where the function a call is located may be set to "-1" to indicate that the function a call has no parent call.

FIG. 3 illustrates a flow diagram of a method of determining the runtime of a function itself, according to one embodiment of the present disclosure.

In a possible implementation manner, referring to fig. 3, in the step 102, determining, from the index file, the record location identifier of the corresponding record of the first function and the sub-function of the first function in the log file according to the record location identifier and the call relationship, may include:

and 1023, determining the position sequence number corresponding to the entry record of the first function in the index file as the first entry record position sequence number of the entry record of the first function in the log file.

Step 1024, determining an index number corresponding to the position sequence number corresponding to the entry record of the first function in the index file, and determining the index number as the first exit record position sequence number of the exit record of the first function in the log file.

Still taking the above example as an example, assuming that the first function is function a, and the location sequence number corresponding to the incoming record of function a is 0, it may be determined that the first incoming record location sequence number corresponding to the incoming record of function a in the log file is 0. If the index number corresponding to the position sequence number 0 is 5, the first record output position sequence number corresponding to the record output of the function a in the log file is 5.

And 1025, when an index number consistent with the first recording position sequence number exists, determining that the position sequence number corresponding to the index number is a second recording position sequence number of the second function recorded in the log file, wherein the second function is a sub-call of the first function.

And step 1026, determining a position sequence number corresponding to the index number in the index file, which is consistent with the second recording position sequence number, as a second recording position sequence number of the recording of the second function in the log file.

For example, the index number corresponding to the position sequence number of the outgoing record in the index file is the same as the position sequence number of the incoming record where the parent call of the function call in the outgoing record is located. That is, when there is an index number that is consistent with the location sequence number of the entry of the first function, it may be determined that the first function calls as a parent of another function, that is, there is a second function that calls with the first function as a parent.

When it is determined that there is an index number that is consistent with the location number of the entry record of the first function, since the index number corresponding to the location number of the exit record in the index file is the same as the location number of the entry record where the parent call of the function call in the exit record is located, it can be determined that the location number corresponding to the index number is the second exit record location number of the exit record of the second function that calls the first function as the parent, and thus the location number corresponding to the index number that is consistent with the second exit record location number is the second entry record location number of the entry record of the second function.

Still taking the above example as an example, if the position sequence number corresponding to the entry of the function a is 0, and there is a position sequence number corresponding to the index number 0 (the first entry position sequence number of the entry of the function a), and the position sequence numbers are 2 and 4, then it can be determined that there is a sub-call with the function a: and the position serial number 2 is a second recording position serial number of the recording of the second function (function b), and the position serial number 1 corresponding to the index number consistent with the position serial number 2 is a second recording position serial number of the second function (function b). The position number 4 is a second out-recording position number of the out-recording of the second function (function c), and the position number 3 corresponding to the index number that is consistent with the position number 4 is a second in-recording position number of the second function (function c).

In a possible implementation manner, the determining, in step 104, the self-running time of the first function according to the first function and the record of the sub-function of the first function in the log file may include:

For example, a difference between a first outgoing call time recorded in an outgoing record of a first function and a first incoming call time recorded in an incoming record of the first function may be determined as a running time corresponding to the first function, and since there is a second function called by taking the first function as a parent, the running time corresponding to the first function includes a running time of the first function itself and a running time of the second function.

After determining a second exit record position sequence number corresponding to an exit record corresponding to the second function and a second entry record position sequence number corresponding to an entry record corresponding to the second function, the exit record and the entry record of the second function may be obtained from the log file according to the second exit record position sequence number and the second entry record position sequence number, and a difference between a second exit call time recorded in the exit record of the second function and a second entry call time recorded in the entry record of the second function is determined as an operation time of the second function.

The difference between the running time of the first function and the running time of the second function can be determined as the self running time of the first function.

when no index number consistent with the position sequence number corresponding to the entry record of the first function exists in the index file, determining that the first function does not call any function;

and determining the running time corresponding to the first function as the self running time of the first function.

For example, the index number corresponding to the position sequence number of the outgoing record in the index file is the same as the position sequence number of the incoming record where the parent call of the function call in the outgoing record is located. That is, when there is no index number that is consistent with the location sequence number of the entry record of the first function, it may be determined that the first function is not called as a parent of another function, that is, the first function does not call any function.

Still taking the above example as an example, assuming that the first function is the function b, and the location number corresponding to the entry record of the function b is 1, it may be determined that the first entry record location number of the entry record of the function b in the log file is 1. If the index number corresponding to the position sequence number 1 is 2, it can be determined that the first record output position sequence number corresponding to the record output of the function b is 2. If there is no position sequence number corresponding to the index number 1 (the first entry position sequence number of the entry record of the function b) in the index file, the function b does not call any function.

For example, when the first function does not call any function, the runtime of the first function is the runtime of the first function itself. The entry record of the first function can be obtained from the log file according to the first entry position sequence number of the first function, the exit record of the first function can be obtained from the log file according to the first exit position sequence number of the first function, the difference value between the first exit call time recorded in the record and the first entry call time recorded in the entry record is determined, the difference value is the running time of the first function, and the running time of the first function is determined to be the running time of the first function.
