Report tests that fail or error during initial enumeration

[kgilpin]

When the solver encounters a test case that fails or errors during initial test selection, report the test path and the error.

This can be used to identify problems with the test harness that result in missed / failed solutions.

An example:

Title: Report Test Path and Error for Failing or Erroneous Tests in Initial Enumeration

Problem: When executing the initial test selection phase, some test cases fail or encounter errors, as observed in the provided error log. During this process, the specific path of the test and the corresponding error should be reported to aid in diagnosing and resolving issues within the test harness. These failures or errors may lead to undetected or failed solutions, making it imperative to report the issues promptly.

Analysis: In the example provided, a UnicodeEncodeError occurs during database setup, revealing a problem in encoding certain Unicode characters. Errors like these during the initial test enumeration can halt the process, leading to missed solutions or incorrect assumptions about test success. To effectively diagnose these issues, the system should report the specific test path that caused the error and the associated error message. This information can inform debugging efforts and allow for quick resolution of underlying issues in the test harness or the test environment configuration.

Proposed Changes:

1. solver/solve_instance.py:

   • Enhance error handling to capture and log the test path and error message when a test case fails or errors during initial test selection. This should be done by modifying the report_error function to include additional information about the test path along with the error details.

2. solver/workflow/summarize_test_errors.py:

   • Integrate a mechanism to capture the specific test path related to the encountered error when summarizing test errors. Update the summarize_test_errors function to extract and return the test path alongside the error messages.

3. swebench/harness/grading.py:

   • Update the evaluation-related functions to ensure they can accommodate additional reporting of test paths and errors. Specifically, modify functions such as get_eval_report or utility functions to return more detailed error information when failures occur.

4. swebench/harness/run_evaluation.py:

   • Adjust the error handling process within the test execution to ensure that when an error such as UnicodeEncodeError occurs, the system reports the full details, including the test path and error, to the calling functions.

@dividedmind this test fails without any modification by us; any thoughts on why it's blowing up on this encoding issue?

[kgilpin]

Tests can fail because of things like specific environment setup that's needed; we do need to filter these out, as we do, but I don't think we should spend time to track down each one.

why it's blowing up on this encoding issue?

My guess is that it's due to the container environment being incomplete and not setting locale correctly. Setting PYTHONIOENCODING=utf-8 in the environment might help.
