fix: restore STT CI coverage and fix GTK test race

[Coldaine]

User description

Summary

This PR addresses critical gaps identified during the post-merge review of the CI/CD pipeline and test harness.

Changes

1. CI / STT Coverage:

   • Added a dedicated Run Moonshine E2E Tests step to the hosted CI runner.
   • Explicitly installs required Python dependencies (transformers, torch, librosa, accelerate) which were previously missing, causing tests to be skipped or fail silently.
   • Enables the moonshine feature flag for the test run.
   • Resolves CI: Verify Golden Master tests (Moonshine) run and have dependencies on hosted runners #307.

2. Tests / GTK Harness:

   • Fixed a race condition in gtk_test_app.c where the readiness signal file was created before the main loop started.
   • Moved file creation to a g_idle_add callback, ensuring the app is truly responsive before tests attempt injection.
   • Addresses Tests: make GTK test app readiness signaling robust (avoid stale /tmp false-ready) #302.

Verification

• CI should now run and pass moonshine_e2e tests (verifying model download and inference).
• GTK integration tests should show improved stability (fewer flaky failures due to early injection).

Below is a summary of compliance checks for this PR:

Security Compliance
⚪	Buffer overflow risk Description: The filepath buffer uses snprintf with a fixed 256-byte buffer and unsanitized PID, which could potentially overflow if PID values become extremely large on some systems, though this is unlikely in practice. gtk_test_app.c [25-26] Referred Code char filepath[256]; snprintf(filepath, sizeof(filepath), "/tmp/coldvox_gtk_test_%d.txt", getpid());

PR Compliance Guide 🔍

Below is a summary of compliance checks for this PR:

Security Compliance
⚪	Unpinned pip dependencies Description: CI installs unpinned Python packages (pip install transformers torch librosa accelerate) at runtime, which can introduce supply-chain risk and non-reproducible builds if a compromised or breaking release is pulled. ci.yml [202-210] Referred Code - name: Run Moonshine E2E Tests if: matrix.rust-version == 'stable' run: | echo "=== Running Moonshine E2E Tests ===" # Install Python dependencies for Moonshine pip install transformers torch librosa accelerate export PYTHONPATH=$(python3 -c "import site; print(site.getsitepackages()[0])") # Run the specific E2E test with the moonshine feature enabled cargo test -p coldvox-stt --features moonshine --test moonshine_e2e -- --nocapture
Ticket Compliance
🟡	🎫 #307 🟢 CI workflow explicitly enables the necessary features for Golden Master / Moonshine tests (e.g., --features moonshine or --all-features) so tests are not silently compiled out. CI workflow installs required Python dependencies for Moonshine (e.g., transformers, torch, etc.), ideally via a requirements file (e.g., requirements-stt.txt) or similar mechanism. ⚪ Tests pass on the hosted runner (including model download/inference behavior, CPU-only if intended).
🟡	🎫 #302 🟢 The change remains simple and does not add new heavyweight dependencies. 🔴 Readiness wait cannot be satisfied by a stale /tmp file from a previous run (e.g., due to PID reuse). If the GTK app crashes early, tests fail fast with a clear error (e.g., by polling child.try_wait() while waiting).

🔴	Generic: Robust Error Handling and Edge Case Management Objective: Ensure comprehensive error handling that provides meaningful context and graceful degradation Status: Silent I/O failure: The new create_ready_file callback silently ignores fopen failures (no error propagation or logging), making readiness signaling failures hard to diagnose.

⚪	Generic: Security-First Input Validation and Data Handling Objective: Ensure all data inputs are validated, sanitized, and handled securely to prevent vulnerabilities Status: Insecure temp file: The readiness file is written to a predictable /tmp path using snprintf and fopen without secure temp-file creation (e.g., mkstemp), which may be vulnerable to symlink/hijack risks depending on execution context.

Explore these optional code suggestions:

Category	Suggestion	Impact
General	✅ Add error handling for file creation Suggestion Impact: The commit added error handling that logs failures via perror when creating the ready file fails. It also replaced fopen with a more secure open(O_CREAT|O_EXCL) approach and added additional error handling for writing PID content. code diff: static gboolean create_ready_file(gpointer user_data) { char filepath[256]; snprintf(filepath, sizeof(filepath), "/tmp/coldvox_gtk_test_%d.txt", getpid()); - FILE *f = fopen(filepath, "w"); - if (f != NULL) { - // Write empty content - file existence is the signal - fclose(f); + + // Securely create the file: O_CREAT | O_EXCL prevents clobbering or symlink attacks + int fd = open(filepath, O_WRONLY | O_CREAT | O_EXCL, 0600); + if (fd == -1) { + perror("Failed to create ready file"); + return G_SOURCE_REMOVE; // Do not retry; tests will handle absence } + + // Write the PID to the file so tests can verify content is from the current process + char pidbuf[32]; + int len = snprintf(pidbuf, sizeof(pidbuf), "%d", getpid()); + if (len > 0) { + ssize_t w = write(fd, pidbuf, (size_t)len); + if (w < 0) { + perror("Failed to write PID to ready file"); + } + } + + close(fd); Add error handling to the create_ready_file function by logging a message to stderr if the fopen call fails. crates/coldvox-text-injection/test-apps/gtk_test_app.c [24-33] static gboolean create_ready_file(gpointer user_data) { char filepath[256]; snprintf(filepath, sizeof(filepath), "/tmp/coldvox_gtk_test_%d.txt", getpid()); FILE *f = fopen(filepath, "w"); if (f != NULL) { // Write empty content - file existence is the signal fclose(f); + } else { + perror("Failed to create ready file"); } return G_SOURCE_REMOVE; // Run once } [Suggestion processed] Suggestion importance[1-10]: 7 __ Why: The suggestion correctly identifies a silent failure case if fopen fails and proposes adding error logging, which significantly improves the debuggability of the test application.	Medium
High-level	Consolidate Python dependencies into requirements files To improve maintainability, consolidate the multiple inline pip install commands in the CI workflow into dedicated requirements.txt files for each test suite. Examples: .github/workflows/ci.yml [207] pip install transformers torch librosa accelerate Solution Walkthrough: Before: # .github/workflows/ci.yml - name: Run Golden Master Test run: | pip install faster-whisper cargo test ... - name: Run Moonshine E2E Tests run: | pip install transformers torch librosa accelerate cargo test --features moonshine ... After: # .github/workflows/ci.yml - name: Run Golden Master Test run: | pip install -r requirements-golden-master.txt cargo test ... - name: Run Moonshine E2E Tests run: | pip install -r requirements-stt.txt cargo test --features moonshine ... # requirements-stt.txt would contain: # transformers # torch # librosa # accelerate Suggestion importance[1-10]: 5 __ Why: The suggestion offers a valid best-practice improvement for CI maintainability by proposing requirements.txt files over inline pip install commands, which is relevant to the PR's CI modifications.

[Copilot]

The Python dependencies are installed without version pinning, which can lead to non-reproducible builds and potential security issues if a dependency is compromised. Consider pinning versions (e.g., pip install transformers==4.36.0 torch==2.1.2 librosa==0.10.1 accelerate==0.25.0) or using a requirements file to ensure consistent test environments across runs.

⚠️ WARNING: Missing error handling in create_ready_file function

The create_ready_file function doesn't handle or log failures when fopen() returns NULL, which could cause silent test failures. Consider adding error logging similar to what's done in the on_text_changed function.
