-Why that is a problem: -- `jq` expects JSON. Raw HTML is not JSON, so `jq` will fail with a parse error. -- `file_get_contents()` over `https://...local` can fail with SSL verification (self-signed certs) or network resolution in the container/PHP environment. -- HTML contains quotes/newlines/binary bytes, which can break shell quoting or JSON encoding if not handled. -- WP-CLI `wp eval` prints whatever your PHP echoes; there’s no automatic JSON wrapping. - -Safe alternatives (copyable): - -1) Return JSON-encoded HTML so `jq` can parse it: -```sh -local-wp "$1" wp eval "echo json_encode(file_get_contents('https://$1.local'));" | jq -r . -``` - -2) Use base64 to avoid encoding/UTF-8 issues, then decode locally: -```sh -local-wp "$1" wp eval "echo base64_encode(file_get_contents('https://$1.local'));" | base64 --decode > page.html -``` - -3) Use `curl` from the host (or from within the container) instead of `file_get_contents`: -```sh -# From host (if DNS resolves to local dev) -curl -sS https://example.local -k > page.html # -k if cert is self-signed - -# Or via WP container (if local-wp exposes a shell) -local-wp "$1" wp ssh "curl -sS https://$1.local -k" -``` - -4) Use WordPress HTTP API inside `wp eval` for more control: -```sh -local-wp "$1" wp eval "echo json_encode(wp_remote_retrieve_body(wp_safe_remote_get('https://$1.local')));" | jq -r . -``` - -Recommendations: -- If you want the assistant to “see” raw HTML reliably, prefer base64 (safe transport) or `json_encode` (if you want JSON). Base64 avoids encoding/character issues. -- If SSL/self-signed certs are a problem, use curl with `-k` or configure the PHP stream context / WP_HTTP to ignore verification (only for dev). -- Validate that `local-wp` runs in an environment that can resolve `*.local` and reach the site. - -Want me to add a small helper script (`local-browser`) implementing the base64-safe version and test it in the repo? \ No newline at end of file diff --git a/PROJECT/1-INBOX/FIX-CICD.md b/PROJECT/1-INBOX/FIX-CICD.md deleted file mode 100644 index 0fdf521..0000000 --- a/PROJECT/1-INBOX/FIX-CICD.md +++ /dev/null @@ -1,89 +0,0 @@ -# FIX-CICD: CI fixture tests failing on Ubuntu (jq missing) - -**Created:** 2026-01-09 -**Status:** Not Started -**Priority:** High - -## Problem/Request -GitHub Actions CI was failing (9/10 fixture tests failing on Ubuntu) while passing locally on macOS. - -## Root Cause (confirmed) -The fixture test runner [dist/tests/run-fixture-tests.sh](../../dist/tests/run-fixture-tests.sh) parses scanner output as JSON using `jq`. - -- In GitHub Actions Ubuntu runners, `jq` is not guaranteed to be present. -- When `jq` is missing, the script’s JSON-parse branch fails and it falls back to *text* parsing. -- Because [dist/bin/check-performance.sh](../../dist/bin/check-performance.sh) defaults to JSON output (`OUTPUT_FORMAT="json"`), the text parsing fallback fails too. - -## Code Review Findings - -### ✅ What’s good -- **Correct fix direction:** Installing `jq` in CI aligns with a JSON-first architecture and also supports Slack/report tooling in [ .github/workflows/ci.yml](../../.github/workflows/ci.yml). -- **Avoids weakening tests:** Not forcing `--format text` keeps parsing stable and avoids brittle greps for human output. -- **Script already has some resilience:** The fixture runner strips ANSI codes and captures output to temp files, which helps keep parsing deterministic. - -### ⚠️ Correctness / Robustness gaps -1. **`jq` absence triggers the wrong fallback path** - - In [dist/tests/run-fixture-tests.sh](../../dist/tests/run-fixture-tests.sh), the decision boundary is “can I run `jq empty`?” rather than “is the output JSON?”. - - Result: if output *is* JSON but `jq` is missing, the script attempts text parsing, which is structurally incapable of working. - -2. **Implicit reliance on default output format** - - `run_test()` calls `check-performance.sh` without `--format json`, relying on its default. - - That’s currently stable (default is documented as JSON), but making it explicit would strengthen the contract between the test runner and the scanner. - -3. **CHANGELOG inconsistency / mixed narrative** - - In [CHANGELOG.md](../../CHANGELOG.md) under **Unreleased → Fixed → Test Suite**, it claims: - - “Fixed JSON parsing in test script to use grep-based parsing (no jq dependency)” - - But the current script is `jq`-primary and CI explicitly installs `jq`. - - The entry also says both “All 10 fixture tests now pass” and later “(9/10 tests passing)”, which reads as contradictory. - -4. **Duplication in CI dependency installation** - - [ .github/workflows/ci.yml](../../.github/workflows/ci.yml) installs `jq` in both jobs separately. - - This is fine, but it’s repeated maintenance surface. - -## Recommendations (no code changes requested) - -### 1) Make jq a declared prerequisite *or* make JSON parsing dependency-free -Pick one and make it consistent across CI + docs: - -- **Option A (declare jq required):** - - Treat `jq` as a hard dependency of the fixture runner. - - In CI, keep installing it. - - In local/dev, add a clear early check like `command -v jq` and fail with an actionable error message. - -- **Option B (remove jq dependency):** - - Replace the `jq` parsing path in `run_test()` with a dependency-free JSON extraction (e.g., minimal grep extraction, or `python3 -c` JSON parsing). - - This matches the existing “no jq dependency” statements in the changelog. - -### 2) Don’t use “text parsing” as a fallback for “jq missing” -If you keep a fallback: -- First detect whether output is JSON (e.g., begins with `{` after stripping ANSI). -- If output is JSON but `jq` is missing, either: - - fail with a clear message, or - - use a dependency-free JSON parser fallback. - -### 3) Make format explicit in tests -Even if the scanner default remains JSON: -- Have the fixture tests call `check-performance.sh --format json` consistently. -- This prevents future surprises if the scanner’s default changes. - -### 4) Clarify and reconcile CHANGELOG statements -Update the Unreleased entry so it matches reality: -- If CI installs `jq` and tests rely on it, remove/adjust the “no jq dependency” claim. -- Fix the “All 10 pass” vs “9/10 pass” inconsistency. - -### 5) CI hardening (optional) -- Print `jq --version` after install for easier diagnosis. -- Consider using `sudo apt-get install -y jq` (with update) as you already do; it’s fine. -- If apt install is a concern, failing the job is acceptable because tests can’t run correctly without `jq` under the current design. - -## Edge Cases / Risks to watch -- **Runner image changes:** `ubuntu-latest` can change; explicit installation avoids surprises. -- **JSON schema changes:** Tests assume `.summary.total_errors` and `.summary.total_warnings` exist. - - If the JSON schema changes, the tests should fail loudly (ideally with a clear schema mismatch message). -- **Non-JSON noise:** Any stderr logging mixed into JSON output will break parsing. - - Scanner already has safeguards to avoid corrupting JSON;

AST Parser Timeline -**Question:** Should we invest in AST now or wait until Phase 1-2 results? - -**Recommendation:** Wait. Regex improvements will get us to 90% accuracy. AST is a 3-month project for the last 10%. - -### 2. Performance vs Accuracy Trade-off -**Question:** Is it acceptable to scan 10 lines of context (slower) for better accuracy? - -**Recommendation:** Yes. Context window of 10-20 lines is negligible performance impact. - -### 3. Backward Compatibility -**Question:** Should we maintain old behavior with a flag? - -**Recommendation:** Yes. Add `--legacy-mode` flag to disable context awareness. - -### 4. Severity Levels -**Question:** Should we add `INFO` severity for "technically correct but could be better"? - -**Recommendation:** Yes.

These are practical as "early warning" grep rules, but should be marked as **contextual** (review-required) to avoid false positives. -- **Best candidates**: 1, 2, 6, 7 (clear anti-pattern intent, low ambiguity in SBI context). -- **Higher risk of false positives**: 3, 4, 5 (common strings in unrelated files or legitimate uses). -- **Recommendation**: Keep them as "warning" severity, add scope hints (PHP/JS files) and regex anchoring where possible. - ---- - -## 1) Multiple Refresh Endpoints / Overlapping Actions -**Problem**: Different AJAX actions for the same behavior increase brittleness and inconsistency. - -**GREP Patterns** -- `sbi_refresh_repository` -- `sbi_refresh_status` - -**Generic Pattern (`wp-check`):** -```json -{ - "id": "overlapping-actions", - "severity": "warning", - "description": "Detects likely overlapping refresh-related AJAX actions", - "grep": "\\b([a-z0-9_]+_)?refresh_(repository|status|data|cache)\\b" -} -``` - -**Interpretation** -- If both appear in active code paths, you likely have redundant refresh flows. -- **Viability**: High.
