ArXiv Paper

AutoCodeRover is a fully automated approach for resolving GitHub issues (bug fixing and feature addition) where LLMs are combined with analysis and debugging capabilities to prioritize patch locations ultimately leading to a patch.

AutoCodeRover resolves ~16% of issues of SWE-bench (total 2294 GitHub issues) and ~22% issues of SWE-bench lite (total 300 GitHub issues), improving over the current state-of-the-art efficacy of AI software engineers.

AutoCodeRover works in two stages:

• 🔎 Context retrieval: The LLM is provided with code search APIs to navigate the codebase and collect relevant context.
• 💊 Patch generation: The LLM tries to write a patch, based on retrieved context.

AutoCodeRover has two unique features:

• Code search APIs are Program Structure Aware. Instead of searching over files by plain string matching, AutoCodeRover searches for relevant code context (methods/classes) in the abstract syntax tree.
• When a test suite is available, AutoCodeRover can take advantage of test cases to achieve an even higher repair rate, by performing statistical fault localization.

As an example, AutoCodeRover successfully fixed issue #32347 of Django. See the demo video for the full process:

AutoCodeRover can resolve even more issues, if test cases are available. See an example in the video:

We recommend running AutoCodeRover in a Docker container.

Set the OPENAI_KEY env var to your OpenAI key:

export OPENAI_KEY=sk-YOUR-OPENAI-API-KEY-HERE

Build and start the docker image:

docker build -f Dockerfile -t acr .
docker run -it -e OPENAI_KEY="${OPENAI_KEY:-OPENAI_API_KEY}" acr

Dockerfile.scratch will build both SWE-bench (from https://github.com/yuntongzhang/SWE-bench.git) and ACR. That supports arm64 (Apple silicon) and ppc in addition to amd64.

docker build -f Dockerfile.scratch -t acr .

There are build args for customizing the build like this:

docker build --build-arg [email protected] --build-arg GIT_NAME=your_id \
       --build-arg SWE_BENCH_REPO=https://github.com/your_id/SWE-bench.git \
       -f Dockerfile.scratch -t acr .

If you want to use AutoCodeRover for new GitHub issues in a project, prepare the following:

• Link to clone the project (used for git clone ...).
• Commit hash of the project version for AutoCodeRover to work on (used for git checkout ...).
• Link to the GitHub issue page.

Then, in the docker container (or your local copy of AutoCodeRover), run the following commands to set up the target project and generate patch:

cd /opt/auto-code-rover
conda activate auto-code-rover
PYTHONPATH=. python app/main.py --mode fresh_issue --output-dir output --setup-dir setup --model gpt-4-0125-preview --model-temperature 0.2 --fresh-task-id <task id> --clone-link <link for cloning the project> --commit-hash <any version that has the issue> --issue-link <link to issue page>

The <task id> can be any string used to identify this issue.

If patch generation is successful, the path to the generated patch will be printed in the end.

Instead of cloning a remote project and run ACR on an online issue, you can also prepare the local repository and issue beforehand, if that suits the use case. For running ACR on a local issue and local codebase, do

PYTHONPATH=. python app/main.py --mode fresh_issue --output-dir output --model gpt-4-0125-preview --model-temperature 0.2 --fresh-task-id <task id> --local-repo <path to the local project repository> --issue-file <path to the file containing issue description>

In the docker container, we need to first set up the tasks to run in SWE-bench (e.g., django__django-11133). The list of all tasks can be found in conf/swe_lite_tasks.txt.

The tasks need to be put in a file, one per line:

cd /opt/SWE-bench
echo django__django-11133 > tasks.txt

Or if running on arm64 (e.g. Apple silicon), try this one which doesn't depend on Python 3.6 (which isn't supported in this env):

echo django__django-16041 > tasks.txt

Then, set up these tasks by running:

cd /opt/SWE-bench
conda activate swe-bench
python harness/run_setup.py --log_dir logs --testbed testbed --result_dir setup_result --subset_file tasks.txt

Once the setup for this task is completed, the following two lines will be printed:

setup_map is saved to setup_result/setup_map.json
tasks_map is saved to setup_result/tasks_map.json

The testbed directory will now contain the cloned source code of the target project. A conda environment will also be created for this task instance.

If you want to set up multiple tasks together, put their ids in tasks.txt and follow the same steps.

Before running the task (django__django-11133 here), make sure it has been set up as mentioned above.

cd /opt/auto-code-rover
conda activate auto-code-rover
PYTHONPATH=. python app/main.py --enable-layered --model gpt-4-0125-preview --setup-map ../SWE-bench/setup_result/setup_map.json --tasks-map ../SWE-bench/setup_result/tasks_map.json --output-dir output --task django__django-11133

The output of the run can then be found in output/. For example, the patch generated for django__django-11133 can be found at a location like this: output/applicable_patch/django__django-11133_yyyy-MM-dd_HH-mm-ss/extracted_patch_1.diff (the date-time field in the directory name will be different depending on when the experiment was run).

First, put the id's of all tasks to run in a file, one per line. Suppose this file is tasks.txt, the tasks can be run with

cd /opt/auto-code-rover
conda activate auto-code-rover
PYTHONPATH=. python app/main.py --enable-layered --model gpt-4-0125-preview --setup-map ../SWE-bench/setup_result/setup_map.json --tasks-map ../SWE-bench/setup_result/tasks_map.json --output-dir output --task-list-file /opt/SWE-bench/tasks.txt

NOTE: make sure that the tasks in tasks.txt have all been set up in SWE-bench. See the steps above.

Alternatively, a config file can be used to specify all parameters and tasks to run. See conf/vanilla-lite.conf for an example. Also see EXPERIMENT.md for the details of the items in a conf file. A config file can be used by:

python scripts/run.py conf/vanilla-lite.conf

Please refer to EXPERIMENT.md for information on experiment replication.
