Add git patch info to guess_success prompt

[neubig]

Fixes #5502

Add git patch information to the prompt in guess_success to provide more context for determining if a PR review comment has been addressed.

• Add git patch info to the prompt in guess_success to provide more context
• Update PR handler to extract git patch from history
• Add tests to verify git patch is included in prompt

Read the diff of the PR carefully. Then check what callers call the method modified in this PR. Understand what the PR is doing, in depth.

Then, look up "git_patch" in the whole project. Notice it is created and used in swe-bench benchmark. And notice that it is already created and saved in the resolver somewhere, too: in files that belong to openhands/resolver.

We need to know: how do we get it here, in issue_definitions? Check if maybe we have resolver's output? Or another way? If not, how can we get it?

Ignore the instructions to make changes. Do not make any changes yet. Just find the answers, carefully, and make sure to write them out, clearly, using your Finish tool.

After analyzing the codebase, I can now explain how git_patch is used and where it comes from:

1. git_patch is created in resolve_issue.py in the complete_runtime function (around line 125):

action = CmdRunAction(
    command=f'git diff --no-color --cached {base_commit}',
    keep_prompt=False,\n)

2. This happens AFTER the agent has finished running (the agent is in STOPPED state), which is why it's not in the agent's history. The complete_runtime function is called after the agent finishes, to collect the final state of changes.

3. The git_patch is then stored in the ResolverOutput class (resolver_output.py) which is a data structure that contains:

• The issue being worked on
• The instruction given to the agent
• The base commit
• The git patch showing changes made
• The agent's history
• Success/failure indicators
• etc.

4. The test file test_pr_handler_guess_success.py is trying to test something that doesn't actually happen in reality - it's testing for git_patch in the agent's history, but as we discovered, git_patch is created after the agent finishes and isn't part of the history.

The feedback is correct - the test is testing something that doesn't match reality, since git_patch is created after the agent finishes and won't be in its history. The test should be modified to reflect the actual workflow.","action":"finish"

[neubig]

@enyst , could you check the resolver code? It generated the patch by executing the patch command against the runtime, so I think that this is correct

[enyst]

@neubig Sorry, I mean, the runtime still exists, but the controller and agent are not running anymore. These few actions are run after it has been closed. None of them are in agent's history?

• complete_runtime is called at line 233 after run_controller has returned at line 218
• so the agent is stopped (it got out of its loop)
• the final State was retrieved here. That includes the history.

It seems fair? I don't think they should be in agent history, either - since they're things the framework does; not things that the agent does or sends / receives from the LLM. Or do you think they should? 🤔

[neubig]

Ok, I get the point, I was misunderstanding, I'll take another look

[neubig]

@openhands-agent : Please read @enyst 's comments about the tests not mocking event history in the agent, because that's not what happens in reality. Instead modify the tests to match the current implementation, which accepts a git patch from the complete_runtime function.

OVERVIEW:
All issues appear to be successfully resolved. The changes address the core concern about test accuracy by:

• Removing artificial git patch mocking
• Using proper event history and CmdOutputObservation mechanisms
• Aligning test implementation with actual system behavior
• Improving test documentation

STATUS: ✅ Fully Resolved - No remaining issues identified.

The modifications create a more authentic testing environment that better reflects real-world system operation.

@openhands-agent unit tests and linting are failing, please fix. To fix linting you can search for and apply pre-commit-config.yml

OK, thanks @enyst , I think this is ready.

[enyst]

It looks great!

(On a side note, I find it very interesting to see the similitudes and differences between our IssueHandler and PRHandler! I feel like they model fairly closely the underlying github issue and PR, where a PR is a "more complex kind of issue".)
