feat: add Dockerfile and docker-compose.yml indexing

[marxo126]

Summary

• New pipeline phase (Phase 2.1) that parses Docker infrastructure files into Service and Image graph nodes
• Two new node types: Service (name, image, ports, buildContext, environmentKeys) and Image (name, tag)
• Three new edge types: USES_IMAGE (Service→Image), DEPENDS_ON (Service→Service), BUILDS_FROM (Service→File)
• Line-by-line parsers with dynamic indentation detection — no external YAML dependency
• Full LadybugDB schema registration: NODE_TABLES, CSV generator, COPY queries, RELATION_SCHEMA FROM/TO pairs

Detection

Dockerfile: Parses FROM (image:tag, multi-stage, registry prefixes), EXPOSE (single/multi-port)

docker-compose.yml: Parses services (name, build context/dockerfile, image, ports, depends_on, environment keys). Handles 2-space, 4-space, and any consistent indentation. Strips trailing YAML comments.

File patterns: Dockerfile, Dockerfile.*, *.dockerfile, docker-compose*.yml, compose*.yml

Example queries

-- Find all services and their images
MATCH (s:Service) RETURN s.name, s.image, s.ports

-- Find service dependencies
MATCH (s:Service)-[:CodeRelation {type: 'DEPENDS_ON'}]->(d:Service) RETURN s.name, d.name

-- Find which Dockerfile builds a service
MATCH (s:Service)-[:CodeRelation {type: 'BUILDS_FROM'}]->(f:File) RETURN s.name, f.filePath

Test plan

• 13 unit tests for Dockerfile parser (multi-stage, registry prefix, multi-port) and docker-compose parser (services, build, image, ports, depends_on, environment)
• 8 integration tests running full pipeline on fixture with Dockerfile + docker-compose.yml (verifies all node types and edge types)
• Validated against real project with multiple compose files (correctly detected 5 services, dependency graph, 6 images)

Hey @marxo126 ,

You have been contributing to our GitNexus OSS and making it better day by day. I would like to ask if you know that we have a Discord community where we talk about all the issues and future plans of GitNexus OSS. It would be greate if you could join. :)

[marxo126]

Hey @magyargergo, thanks for the invite! I didn't know about the Discord — I've been too focused on making GitNexus production-ready for our projects and for everyone else to use. Just joined! 🙌

⚠️ Verdict: NOT ready to merge — several issues need to be addressed

---

🚨 Critical: PR Title & Description Don't Match the Code

This PR is titled "feat: add Dockerfile and docker-compose.yml indexing" with a description about Service/Image nodes and Docker parsing — but the actual commits implement BullMQ + Temporal async queue detection (ENQUEUES/PROCESSES edges). There is zero Docker-related code in this diff.

The PR title, description, and example queries must be updated to reflect what the code actually does before merging. This isn't cosmetic — reviewers and future contributors will be confused about what changed and why.

---

🔴 Issue 1: Dangerous Code Duplication

The queue detection regex logic is copy-pasted in two places:

• parse-worker.ts:382–391 — extractQueuePatterns() with module-level const regexes
• pipeline.ts:814–833 — the same logic inlined verbatim

The fix commit explains this was done to avoid importing worker-thread code, which is a real constraint. But the correct fix is to extract the regex logic into a shared utility file (e.g., gitnexus/src/core/ingestion/utils/queue-detection.ts) that contains no worker-thread imports — both parse-worker.ts and pipeline.ts can safely import a plain utility. Leaving two diverging copies of detection logic is a maintenance trap.

Fix this →

---

🔴 Issue 2: Missing Null Guard in parsing-processor.ts

The ormQueries field already has a defensive guard, but queuePatterns doesn't:

// parsing-processor.ts ~line 110
if (result.ormQueries) allORMQueries.push(...result.ormQueries);  // ✅ guarded
allQueuePatterns.push(...result.queuePatterns);                    // ❌ no guard — crashes if undefined

If any worker result is missing queuePatterns (e.g., from a stale build artifact or an older code path), this will throw at runtime. Apply the same pattern: if (result.queuePatterns) allQueuePatterns.push(...result.queuePatterns);

Fix this →

---

🟡 Issue 3: High False-Positive Risk from Heuristic Pre-Filters

// parse-worker.ts
const hasBullMQ = content.includes('new Queue') || content.includes('new Worker');
const hasTemporal = content.includes('activities.') || content.includes('client.workflow.');

• new Worker matches Node.js worker_threads.Worker and browser Worker — both unrelated to BullMQ. Any file using worker threads will be incorrectly flagged.
• new Queue matches any custom Queue class, PriorityQueue, etc.
• activities. is an extremely broad string — any object named activities in unrelated code (e.g., a fitness app, a CRM) will trigger false positives.

A more precise pre-filter for BullMQ should check for from 'bullmq' or require('bullmq'), and for Temporal: from '@temporalio/ or require('@temporalio/.

---

🟡 Issue 4: Phase Comment Is Out of Order

In pipeline.ts, the new phase comment reads:

// Phase 3.8: Queue/Pipeline Detection (BullMQ + Temporal)

But it's placed before the existing // ── Phase 3.7: ORM Dataflow Detection. The ordering in the comment doesn't match execution order. Either renumber or reorder.

---

🟡 Issue 5: Code Formatting in Inline Block

The inlined logic in pipeline.ts (lines 815–833) uses single-line statement crams and cryptic variable names (qvMap, aRe, wRe, actRe, wfRe). This is unusually hard to read for a production codebase. Even if this block is temporary until duplication is resolved, it should be formatted consistently with the surrounding code.

---

🟡 Issue 6: Weak Test Coverage

The 3 integration tests in queue-detection.test.ts use toBeGreaterThanOrEqual(1) — effectively just checking that something was detected. There are no unit tests for extractQueuePatterns, and no tests for edge cases:

• Multi-queue files
• Files that use new Worker from worker_threads (false-positive regression test)
• Temporal workflows without a variable named activities
• Files where queue variable is passed as an argument

The PR description claims "13 unit tests for Dockerfile parser" — these don't exist. The actual test count is 3 weak smoke tests.

---

✅ What Looks Good

• Schema registration (schema.ts, types.ts) is correct — ENQUEUES and PROCESSES are properly added to REL_TYPES and RelationshipType.
• CI passes: all 4333 tests pass, TypeScript compiles clean.
• Pipeline integration follows the existing ORM detection pattern (processQueuePatterns modeled after processORMQueries).
• Fixture files are minimal and clearly demonstrate the intended use cases.
• Edge directionality (File → QueueNode) is consistent with ORM detection.

---

Summary

Issue	Severity	Required for merge?
PR title/description mismatch	🚨 Critical	Yes
Logic duplicated in pipeline.ts + parse-worker.ts	🔴 High	Yes
Missing null guard in parsing-processor.ts	🔴 High	Yes
False-positive heuristics (new Worker, activities.)	🟡 Medium	Recommended
Phase comment ordering	🟡 Medium	No
Code formatting in inline block	🟡 Medium	Recommended
Weak test coverage	🟡 Medium	Recommended

The core idea is sound and the schema/pipeline integration is well-structured, but the duplication issue and null guard are functional bugs that should be resolved before merging.

⚠️ Upcoming Prettier formatting — rebase instructions

PR #563 adds Prettier as the code formatter for the repo. When it merges, the bulk format commit will touch ~350 files (style-only: whitespace, quotes, trailing commas). Your branch will likely conflict.

After #563 merges, rebase your branch:

git fetch origin
git checkout <your-branch>
git rebase origin/main

# Conflicts will be formatting-only — accept your version:
git checkout --theirs .
git add .
git rebase --continue

# Then re-format your branch to match the new style:
npx prettier --write .
git add -A
git commit -m "style: apply prettier formatting"
git push --force-with-lease

New setup step: Run npm install at the repo root (not just in gitnexus/) to get prettier + activate the pre-commit hook. The hook auto-formats staged files on every commit going forward.
