Hi, your TBar tool is very useful and can fix a lot of bugs. But I found that there could be some implementation missing in the included fix patterns, e.g., LiteralExpressionMutator. I would assume this mutator can mutate string to another string (e.g., "") and mutate numbers to some other numbers (default ones like 0, 1 etc. or negated ones), but it seems the implementation is missing, according to your TODOs:

Dear Sir,
Sorry for disturbing you with this issue.

When I am reading the Tbar code, it seems that TBar does not have a time limit for the whole repair process. The only timeout that can be seen in Tbar seems to be the shell_time_out.

So my question is that how Tbar controls the time budget (i.e., 3 hours mentioned in the paper)?

Thanks!
Dale

Hi,

The README.md file mentions that TBar requires Java-7, would it incorrect/wrong to run it under Java-8?

Chart_14.log
Patch_39_1.txt
Patch_502_130.txt
Patch_504_132.txt
Patch_505_133.txt
The first file is the log for trying to fix Chart_14 by TBar, and the following four are patches generated by the tool.
It seems that all patches cannot make all test cases running successfully.

Thanks for your attention.

Hi,
How can I generate BugPositions.txt for a bug from Defects4J?

Thanks for your attention.

Hello, I find that ExpressionReplacer defined in ConditionalExpressionMutator class is not used anywhere.
And I noticed this block of code:

It seems that line 50 should be ExpressionReplacer, not ExpressionRemover again.
Is this a bug?

Math_98.log
This is my log for running TBar to fix Math_98.
It seems that the tool cannot fix "v.length" because the type of the field "length" can not be parsed.

Hi,

It seems TBar is very dependent on D4J, would it be possible to run TBar on any other bug? If so, how?

Thanks in advance.
