Ideally, it should also include the problem statement, but that's not in their JSON file and can't arsed to continue working on it – it's just a quick script I cooked up.
I find it very hard to judge the quality of most of these patches because I'm not familiar with these projects.
However, looking at the SWE-bench dataset I don't think it's representative of real-world issues, so "22% of real-world GitHub issues" is not really accurate regardless.
SWE-bench Lite is a subset of extremely simple issues from a cherry-picked subset (SWE-bench) of a handful of large (presumably well-run) Python-only projects.
Here are some rules they used to trim down the SWE-bench Lite problems:
* We remove instances with images, external hyperlinks, references to specific commit shas and references to other pull requests or issues.
* We remove instances that have fewer than 40 words in the problem statement.
* We remove instances that edit more than 1 file.
* We remove instances where the gold patch has more than 3 edit hunks (see patch).
You can't demonstrate whether a dataset is representative or not by "an example or two". You need to look at all the data.
And all of this is fine. It's just a benchmark suit and doesn't need to be fully representative. The dataset itself doesn't even claim to be that as far as I can find. All I'm saying that the title wasn't really accurate.
The ArXiv paper mentions the human developer must supply a unit test (which can conceivably be coded with at least the assistance of an AI agent if not autonomously coded, but their experiment relies upon the former kind of unit test) that issues a pass-fail signal. So the 78% of failures are clearly identified, at the cost of implementing TDD for the Issue. The side effects story is punted upon, but I’d still take this over the nothing we have today.
Of course, over a relatively short amount of time using this, I’d expect to experience the 22% (or whatever the real rate is) success rate to drop asymptotically towards zero as the low hanging fruit of the approach are mined out and it becomes kind of like another linter in our CICD pipelines.
The impact of this tooling upon staff skills development will be interesting to say the least.
AutoCodeRover does not require or assume a unit test to generate patches. The results discussed in Section 6.1 of the ArXiv paper are generated without any unit test. The unit tests are used by SWE-bench, when evaluating the correctness of AutoCodeRover-generated patches.
That being said, when some unit tests are available (either written by developers or with assistance from other tools), AutoCodeRover can make use of them to perform some analysis like Spectrum-based Fault Localization (SBFL). This kind of analysis output can help the agent in pinpointing locations to fix. (Please see Section 6.2 for the analysis on SBFL.)
> AutoCodeRover does not require or assume a unit test to generate patches.
You have this backwards : it's traditional (at least in the past 15 years or so) to have a test to go along with every code change. The idea is that the test proves a) the bug existed prior to the fix and b) the bug is not there after the fix is applied. Commenters here are noting that ACR generates fixes but not tests.
The previous comment was to describe the experiment settings.
AutoCodeRover currently generates patches. Auto-generating high quality tests can be a parallel effort and another direction to explore. These efforts can eventually be used together.
The short answer is that unit tests are not needed in AutoCodeRover.
The technique proceeds by a sophisticated code search starting from the Github issue. tests are not needed. The code search helps in setting the context for LLM agents - which can help in the patch construction.
If tests are available, they can give additional help in setting code context. But tests are not needed, and most of Github issues are solved without tests.
All experimental numbers appear in the arxiv paper. Please let us know if you have more questions.
Yes, and to be clear, the benchmark used here is merely the 300 simplest problems in the larger benchmark suite, which itself is only a tiny subset of issues from a dozen large (and presumably well-curated) Python projects.
Not to mention that making the code fix is only a tiny part of resolving an issue. There should also be explanations and added test cases. In other words, I doubt the 22% of “fixes” would pass review by the project owner if a human submitted them.
The point is that the success rate is progressing, paper after paper
> The baseline results of Magis (10%), Devin (14%) are evaluated in another subset of SWE-bench, which we cannot directly compare with, so we take the results from their technical reports as a reference.
There's actual SWE jobs where humans sift through this kind of noise. Someone told me they worked such a job recently.
It's a good tool to add pressure and raise expectations.
Maybe this is the future..
They only know the 22% number because unit tests to check for a fix are included in the benchmark. In other words, in a real world situation, the human would still need to double check. The patches this tool generates do not include appropriate tests or explanations and would never pass code review by a qualified human.
