🛡️ Sentinel: [CRITICAL] Fix Process pipe deadlocks - #146
Conversation
Severity: CRITICAL Vulnerability: `Foundation.Process` pipe handling caused deadlocks. Impact: Denial of Service. The application would hang indefinitely if child process output exceeded the ~64KB OS pipe buffer because `waitUntilExit()` was called before draining the pipe. Fix: Refactored synchronous `Process` executions to read from pipes (`readDataToEndOfFile()`) *before* calling `waitUntilExit()`. Also assigned unused streams to `FileHandle.nullDevice` instead of instantiating unread `Pipe()`s. Verification: Statically validated Swift syntax.

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job! For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with New to Jules? Learn more at jules.google/docs. For security, I will only act on instructions from the user who triggered this task. |

Wait for the free limit to reset to keep reviewing this public repository. How can I continue?After more reviews become available, a review can be triggered using the To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits within each organization. For paid Pro and Pro+ reviews, CodeRabbit uses a developer's included PR review attempts over the past 7 days to set the current hourly allowance. At typical activity levels, the full plan allowance applies. Higher sustained activity can lower the allowance until earlier attempts leave the 7-day window. Please refer docs for additional details.

Severity: CRITICAL Vulnerability: `Foundation.Process` pipe handling caused deadlocks and uncatchable exceptions on failed launches. Impact: Denial of Service. The application would hang indefinitely if child process output exceeded the ~64KB OS pipe buffer because `waitUntilExit()` was called before draining the pipe. Additionally, test suites would crash due to uncatchable exceptions if `run()` failed and was swallowed by `try?`. Fix: Refactored synchronous `Process` executions to read from pipes (`readDataToEndOfFile()`) *before* calling `waitUntilExit()`. Assigned unused streams to `FileHandle.nullDevice` instead of instantiating unread `Pipe()`s. Wrapped `run()` calls in proper `do/catch` blocks in tests to prevent crashes on unlaunched processes. Fixed across `AutomationExecutor.swift`, `UniversalControlMouseRelay.swift`, and `OBSWebSocketLiveIntegrationTests.swift`. Verification: Statically validated Swift syntax since tests cannot run in sandbox. Co-authored-by: NSEvent <44446865+NSEvent@users.noreply.github.com>
