Code consistency checking method

A code consistency checking method, characterized in that, comprising the following steps:

• 1) Conduct code duplication detection to the original codes and store the result into the database.
• 2) Retrieve all file information involving the changed codes according to the code version base before the developer submits the changed codes.
• 3) Obtain the information of all duplicated code segments contained in the files involving the changed codes according to the retrieval of the changed files in the database as described in Step 1).
• 4) Compare the changed codes with the duplicated code segments retrieved in Step 3);
• judge whether the changed codes submitted have changed these duplicated code segments. If the answer is NO, there is no inconsistency problem and the detection passes, if YES, perform the next detection.
• 5) According to the retrieval of the files where the duplicated code segments changed by the changed codes lie in the database as described in Step 1), if the files retrieved are not within the list of files involving the changed codes, it indicates some of the duplicated code segments before change are not changed, namely inconsistency problem exists. Report inconsistent code change in such case, but if the files retrieved are within the list of files involving the changed codes, it indicates inconsistency problem may exist, conduct the next checking in such case.
• 6) Compare the changed code with the duplicated code segments in the files within the list of files involving the changed codes retrieved. If the changes of these duplicated code segments are consistent, there is no inconsistency problem. But if the changes of these code segments are inconsistent, there is inconsistency problem. Report inconsistent code change in such a case.
• 7) Run code duplication detection and update the database after changes are submitted.
