Generation of subsequent patches about simfix

[xgdsmileboy]

Exactly, multiple places should be repaired for some bugs in Defects4J. However, after test case purification, bugs in different places may have nothing with each other. In such cases, if all places can be correctly repaired separately, the correct patch should be their combination. Please note, if there is at least one place that is not repaired, we think the repair for the bug is incorrect.

Such as the bug of Chart-22, the combination of Change 1 and Change 2 is not the complete repair according to https://github.com/rjust/defects4j/blob/master/framework/projects/Chart/patches/22.src.patch.

Hope it will help.

Alright, thanks for your quick reply.

Sorry to bother you again. As far as I can tell, SimFix does not create a direct patch file, but rather individual changes that are necessary to pass certain purified test cases. So can the whole patch be seen as the application of all these changes?

I'm curious about this, because for example, Chart-22 has two competing changes to the method removeRow(Comparable) (Change 1, Change 2). Is such a patch automatically considered incorrect (Chart-22 was) if it contains competing changes?
