From 8542a872c67652a4b68419fa11d2d7656ed3dc5f Mon Sep 17 00:00:00 2001 From: Ammar Date: Thu, 6 Nov 2025 15:27:32 +0000 Subject: [PATCH 1/5] =?UTF-8?q?=F0=9F=A4=96=20fix:=20build=20dist/=20befor?= =?UTF-8?q?e=20running=20terminal-bench?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit PR #507 added `dist/` to the terminal-bench archive include paths to fix worker crashes. However, the workflow wasn't building `dist/` before running the benchmark, causing all tasks to fail immediately with: ``` Error running agent for task : Required file /home/runner/work/cmux/cmux/dist missing ``` Now runs `make build` before `make benchmark-terminal` to ensure dist/ exists and contains the compiled worker files. Verified with workflow run #19140594821 which successfully completed the modernize-fortran-build task. --- .github/workflows/terminal-bench.yml | 42 +++++++++++++++------------- 1 file changed, 23 insertions(+), 19 deletions(-) diff --git a/.github/workflows/terminal-bench.yml b/.github/workflows/terminal-bench.yml index 0c75a4c3d..e573f6781 100644 --- a/.github/workflows/terminal-bench.yml +++ b/.github/workflows/terminal-bench.yml @@ -4,34 +4,34 @@ on: workflow_call: inputs: model_name: - description: "Model to use (e.g., anthropic:claude-sonnet-4-5)" + description: 'Model to use (e.g., anthropic:claude-sonnet-4-5)' required: false type: string thinking_level: - description: "Thinking level (off, low, medium, high)" + description: 'Thinking level (off, low, medium, high)' required: false type: string dataset: - description: "Terminal-Bench dataset to use" + description: 'Terminal-Bench dataset to use' required: false type: string - default: "terminal-bench-core==0.1.1" + default: 'terminal-bench-core==0.1.1' concurrency: - description: "Number of concurrent tasks (--n-concurrent)" + description: 'Number of concurrent tasks (--n-concurrent)' required: false type: string - default: "4" + default: '4' livestream: - description: "Enable livestream mode" + description: 'Enable livestream mode' required: false type: boolean default: true sample_size: - description: "Number of random tasks to run (empty = all tasks)" + description: 'Number of random tasks to run (empty = all tasks)' required: false type: string extra_args: - description: "Additional arguments to pass to terminal-bench" + description: 'Additional arguments to pass to terminal-bench' required: false type: string secrets: @@ -42,34 +42,34 @@ on: workflow_dispatch: inputs: dataset: - description: "Terminal-Bench dataset to use" + description: 'Terminal-Bench dataset to use' required: false - default: "terminal-bench-core==0.1.1" + default: 'terminal-bench-core==0.1.1' type: string concurrency: - description: "Number of concurrent tasks (--n-concurrent)" + description: 'Number of concurrent tasks (--n-concurrent)' required: false - default: "4" + default: '4' type: string livestream: - description: "Enable livestream mode" + description: 'Enable livestream mode' required: false default: true type: boolean sample_size: - description: "Number of random tasks to run (empty = all tasks)" + description: 'Number of random tasks to run (empty = all tasks)' required: false type: string model_name: - description: "Model to use (e.g., anthropic:claude-sonnet-4-5, openai:gpt-5-codex)" + description: 'Model to use (e.g., anthropic:claude-sonnet-4-5, openai:gpt-5-codex)' required: false type: string thinking_level: - description: "Thinking level (off, low, medium, high)" + description: 'Thinking level (off, low, medium, high)' required: false type: string extra_args: - description: "Additional arguments to pass to terminal-bench" + description: 'Additional arguments to pass to terminal-bench' required: false type: string @@ -97,6 +97,9 @@ jobs: - name: Generate version file run: ./scripts/generate-version.sh + - name: Build dist/ + run: make build + - name: Run Terminal-Bench run: make benchmark-terminal env: @@ -120,7 +123,7 @@ jobs: cat "$RESULTS_FILE" | jq '.' || cat "$RESULTS_FILE" echo "" echo "Per-task summary:" - cat "$RESULTS_FILE" | jq -r '.trials[] | "\(.task_id): \(if .is_resolved then "✓ PASS" else "✗ FAIL" end)"' 2>/dev/null || echo "Failed to parse task details" + cat "$RESULTS_FILE" | jq -r '.trials[] | "\(.task_id): \(if .resolved then "✓ PASS" else "✗ FAIL" end)"' 2>/dev/null || echo "Failed to parse task details" else echo "No results.json found in runs/" ls -la runs/ @@ -148,3 +151,4 @@ jobs: runs/ if-no-files-found: warn retention-days: 30 + From aedcbc7a6bf8e3a3e94f59ed6d73dad4a009ebc9 Mon Sep 17 00:00:00 2001 From: Ammar Date: Thu, 6 Nov 2025 15:33:00 +0000 Subject: [PATCH 2/5] =?UTF-8?q?=F0=9F=A4=96=20fix:=20build=20only=20main+p?= =?UTF-8?q?reload=20(skip=20icons)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Icons aren't needed for terminal-bench, and building them requires ImageMagick.

The agentSessionCli reads the user message from stdin, then waits for stream completion. However, once stdin reaches EOF and is consumed, Bun may exit if it detects no other active handles keeping the event loop alive. Add an explicit keepalive interval that ensures the process stays alive until main() completes. This interval runs far into the future but gets cleared in the finally block once the agent session finishes. This fixes the nightly terminal-bench failures where all 80 tasks were failing with agent_timeout and 0 tokens. --- src/debug/agentSessionCli.ts | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) diff --git a/src/debug/agentSessionCli.ts b/src/debug/agentSessionCli.ts index 0b0c0f429..add1a5a56 100644 --- a/src/debug/agentSessionCli.ts +++ b/src/debug/agentSessionCli.ts @@ -488,7 +488,10 @@ async function main(): Promise { } } -void (async () => { +// Keep process alive explicitly - Bun may exit when stdin closes even if async work is pending +const keepAliveInterval = setInterval(() => {}, 1000000); + +(async () => { try { await main(); } catch (error) { @@ -507,5 +510,7 @@ void (async () => { process.stderr.write(`Error: ${message}\n`); } process.exitCode = 1; + } finally { + clearInterval(keepAliveInterval); } })();
