The state of described lock has two kinds usually: locking and release, and when locking, the state of lock is locking, during release, the state of lock is release.
In the present embodiment, use the account of the history of lock chronological file record lock, therefore can preset the lock file, will lock chronological file and be placed in one.Analyze the situation of lock for ease of the staff, will lock tab file and also place in the same lock trace file folder.
Among some embodiment, do not adopt the lock chronological file, and use the lock tab file that the situation of lock is analyzed separately, at this moment, when start-up routine, can be according to default scheme, generate a lock trace file folder according to specified path, will lock tab file and be created in this document folder.
During the S103 release, according to the ID of the lock of release, the corresponding lock of deletion tab file, and in the lock chronological file, write the relevant content of information of this release,, and store.The information of this release comprises ID, release time, code file name, the code of release and the state of lock of lock.
Locking or release information related content can directly be lock ID, lock/the release time, the code file name, lock/code of release and the state of lock.Also can be the content of above-mentioned information after according to certain rule transformation, in a word, as long as can make the analyst according to the related content solution read lock ID, lock/the release time, the code file name, lock/code of release and the state of lock.
The lock chronological file also can place in other the path of setting with the lock tab file.For example in the root directory under certain drive.Analyze and search if program has the lock trace file folder of its correspondence can be convenient to the analyst, for example we can be in the operation catalogue of program, and perhaps other position generates a lock trace file folder.
As lock_trace,
There are two types of files the file the inside, overall chronological file and the tab file of single lock.
The lock chronological file: there is the day-to-day account of all locks the inside.
Content as:
0x3f7789 (locking ID at random), xxyyzz.c (code file name), capable number of 555(), 2013-03-03 15:01:02.005 (time), Lock (locking)
0x3f7789 (locking ID at random), xxyyzz.c (code file name), capable number of 577(), 2013-03-03 15:01:07.005 (time), Lock (release)
In locking or release each time, all can increase the similar content of delegation.
The effect of this file is, record locking and release each time after system's operation, can be utilized the situation that takies of this each lock of file analysis.
The lock tab file: can generate a file under the lock_trace file when locking each time, filename is the ID at random of lock.In release, this file can be deleted
The purpose of design tab file is, program occur deadlock possible in, onlinely at once check the lock_trace file, if there is the tab file of discovery to exist, then the explanation locking is also removed, and directly opens tab file, checks the position of lock.
The content of lock tab file is as follows substantially
Xxyyzz.c (code file name), capable number of 577(), 2013-03-03 15:01:07.005 (time)
Design the locking and unlocking function of all shared locks, complete design is as Lock and Unlock
The requirement of Lock function is to carry out following task:
1) generating the ID that locks, can be to generate random number according to the time;
2) record current code filename and row number;
3) time of record locking;
4) lock.
The performed task of Unlock function is:
1) file of deletion Lock function generation;
2) release.
In different embodiment, the lock chronological file can be distinguished use separately with the lock tab file.But the two is combined, more easily the unusual situation of lock in the analysis judgment system.System occurs directly opening the lock_trace catalogue under the possible situation of deadlock, can observe deadlock position by naked eyes.Can also analyze simultaneously the details of lock according to chronological file.
As shown in Figure 2, present embodiment provides a kind of unusual device 20 of lock that detects, and this device can be PC, server or other electronic equipments, comprises with lower module:
