👺 Havoc: Remove unsafe env mutations#602
Conversation
Replaces `unsafe { std::env::set_var(...) }` calls with `temp_env::with_vars` or
`temp_env::async_with_vars` to prevent data races during concurrent test runs.

Code Review
This pull request replaces unsafe environment variable mutations in tests with the temp-env crate across multiple files, including src/run/mini.rs, src/run/redact_audit.rs, src/stream/sweep_webhook.rs, and src/telemetry/mod.rs. It also simplifies a socket-reading loop in src/run/swebench.rs and improves error reporting in webhook tests. Feedback is provided to remove the temporary Python scripts and the plan.md file that were committed to the repository to keep the codebase clean.
Important
The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.

| 1. **Remove `unsafe` environment variable mutations in `src/run/mini.rs`**. | ||
| - I will replace `unsafe { std::env::set_var(...) }` and `unsafe { std::env::remove_var(...) }` in `mini_manifest_does_not_contain_env_secrets` with `temp_env::async_with_vars`. | ||
|
|
||
| 2. **Remove `unsafe` environment variable mutations in `src/stream/sweep_webhook.rs`**. | ||
| - I will replace `unsafe { std::env::set_var(...) }` and `unsafe { std::env::remove_var(...) }` in `redactor_strips_sensitive_env_var_from_instance_id` with `temp_env::async_with_vars`. | ||
|
|
||
| 3. **Remove `unsafe` environment variable mutations in `src/run/redact_audit.rs`**. | ||
| - I will replace `unsafe { std::env::set_var(...) }` and `unsafe { std::env::remove_var(...) }` in `oracle_catches_ambient_env_value` with `temp_env::with_vars`. | ||
|
|
||
| 4. **Remove `unsafe` environment variable mutations in `src/telemetry/mod.rs`**. | ||
| - I will use a Python script with bash heredoc to replace all `unsafe { std::env::set_var(...) }` usages across several tests in `src/telemetry/mod.rs` with `temp_env::with_vars`. I will also remove `ENV_LOCK`. | ||
|
|
||
| 5. **Run tests** | ||
| - Run `cargo test --lib -- run::mini run::redact_audit stream::sweep_webhook telemetry`. | ||
|
|
||
| 6. Complete pre-commit steps to ensure proper testing, verification, review, and reflection are done. | ||
|
|
||
| 7. Submit the PR. | ||
| - Title: '👺 Havoc: Remove unsafe env mutations' | ||
| - Description: | ||
| * 🧨 **The Trigger:** Test environment mutation via `unsafe { std::env::set_var(...) }` caused data races and panics during concurrent `cargo test` runs on Rust 1.80+. | ||
| * 📉 **The Stack Trace:** (Omitted - data race) | ||
| * 🧪 **Reproduction:** Run `cargo test` concurrently on Rust 1.80+. | ||
| * 😈 **Comment:** You assumed `std::env::set_var` was safe in a single-threaded test. You were wrong. Other concurrent tests will still panic. |

It looks like several temporary Python scripts (replace_*.py, fix_*.py) and the plan.md file itself were committed to the repository. While these scripts are highly useful for automating the refactoring process, they are not part of the application or the test suite. To keep the repository clean and avoid cluttering the codebase with temporary automation artifacts, please delete these files before merging this pull request.
