Date: 2025-10-27 Status: Build #14 Submitting (Pre-built Codi2 Binary Workaround) Context: 42 new @theia packages added, 5 failed builds (#10-#13), workaround implemented

🎯 Quick Handoff (Next Session Start Here)​

Current State: Build #14 FAILED - Build #15 ready to submit with npm --force fix

Build #14 Result (33551863-728f-4052-9e1c-3945a472cefe):

  • ✅ Stages 1-5: All SUCCESS (theia built in 121s!)
  • ❌ Stage 6: npm install -g failed (yarn already exists in node:20-slim)
  • Fix Applied: Added --force flag to npm install (dockerfile.combined-fixed:215)

Immediate Next Steps (15 min):

  1. Submit Build #15: gcloud builds submit --config cloudbuild-combined.yaml . --project=serene-voltage-464305-n2
  2. Monitor: tail -f /tmp/cloud-build-15.log or check console
  3. If SUCCESS → Deploy to GKE (see Deploy section below)

Key Files Modified:

  • dockerfile.combined-fixed:126-143 - Pre-built codi2 binary workaround
  • archive/coditect-v4/codi2/prebuilt/codi2-prebuilt - 16MB pre-built binary
  • theia-app/package.json - 66 @theia packages (42 new)

✅ COMPLETED Work​

Phase 1: Package Updates (Completed)​

Goal: Add 42 missing @theia AI packages to match theia-ide repository

Changes:

  • File: theia-app/package.json
  • Added: 42 new @theia packages (AI, chat, code completion, etc.)
  • Total packages: 66 @theia packages
  • Automation: Created scripts/sync-theia-packages.sh for future updates

Verification:

# Package count verification
grep '@theia' theia-app/package.json | wc -l
# Output: 66

Phase 2: Local theia Build (Completed)​

Goal: Verify theia builds successfully with 66 packages locally

Issue: Initial build ran out of memory (4GB heap default) Solution: Increased Node heap to 8GB

export NODE_OPTIONS="--max-old-space-size=8192"
npm run build

Results:

  • Build time: ~8 minutes (357s + 136s + 130s = 623s)
  • Bundle size: 68.5 MiB (bundle.js)
  • Warnings: 4 webpack warnings (acceptable)
  • Location: Log file /tmp/theia-build-8gb.log

Committed:

  • Dockerfile updated with NODE_OPTIONS=--max-old-space-size=8192 at dockerfile.combined-fixed:91

Phase 3: Cloud Build Attempts #10-#13 (Completed - All Failed)​

Build #10 - FAILED​

Issue: base64ct edition2024 + missing FDB headers in codi2 Root Cause: Dependency version mismatch + FoundationDB not installed in codi2-builder

Build #11 - FAILED​

Issue: Missing libclang in codi2-builder Root Cause: bindgen crate requires libclang for Rust FFI bindings Location: Stage 4 (codi2-builder)

Build #12 - FAILED​

Issue: Missing libclang in v5-backend-builder Root Cause: Same issue, different stage Fix Applied: Added clang + libclang-dev to Stage 3 Commit: 10b8fe7 - "fix: Add clang/libclang-dev to v5-backend-builder stage" File: dockerfile.combined-fixed:105-111

# Stage 3: Build V5 Backend API Server (Rust)
FROM rust:1.82-slim AS v5-backend-builder

# Install build dependencies + FoundationDB client + clang for bindgen
RUN apt-get update && apt-get install -y \
    build-essential \
    libssl-dev \
    pkg-config \
    wget \
    clang \              # ADDED
    libclang-dev \       # ADDED

Build #13 (d0e501ee-95fd-48fb-9506-47bc4204c0e6) - FAILED​

Issue: 30 Rust compilation errors in codi2 Root Cause: Missing tokio-tungstenite dependency in V4 archive code Duration: Build time unknown (failed during codi2 compilation)

Error Categories:

  • E0433/E0432 (4 errors) - Unresolved imports (tokio_tungstenite)
  • E0107 (2 errors) - Wrong number of generic arguments
  • E0223 (13 errors) - Ambiguous associated types in mcp/handlers.rs
  • E0277 (4 errors) - Trait bounds not satisfied (Handler, thread safety)
  • E0505/E0515 (3 errors) - Borrow checker violations
  • E0282/E0308/E0382/E034 (4 errors) - Type inference, moves, scope

Key Affected Files:

  • archive/coditect-v4/codi2/src/websocket/client.rs:5 - Missing import
  • archive/coditect-v4/codi2/src/mcp/client.rs:7 - Missing import
  • archive/coditect-v4/codi2/src/mcp/handlers.rs:154-166 - 13 ambiguous types
  • archive/coditect-v4/codi2/src/websocket/server.rs - Borrow checker errors

Positive: file-monitor (Stage 5) compiled successfully in 26.5s with only 12 warnings

Phase 4: Pre-Built Binary Workaround (Completed)​

Goal: Bypass codi2 compilation errors using pre-built binary

Actions Taken:

  1. Downloaded pre-built codi2 binary v0.2.0 (15.7 MB → 16 MB on disk)
  2. Saved to: archive/coditect-v4/codi2/prebuilt/codi2-prebuilt
  3. Modified Dockerfile Stage 4 to use pre-built binary instead of compiling

Dockerfile Changes (dockerfile.combined-fixed:126-143):

# ============================================================================
# Stage 4: Use Pre-Built Codi2 Monitoring System (WORKAROUND)
# ============================================================================
# NOTE: Using pre-built binary instead of compiling to bypass 30 Rust errors
# Pre-built binary from: gs://serene-voltage-464305-n2-builds/codi2/codi2-*
FROM debian:bookworm-slim AS codi2-builder

WORKDIR /build

# Copy pre-built codi2 binary
COPY archive/coditect-v4/codi2/prebuilt/codi2-prebuilt /build/codi2-binary

# Create expected directory structure for runtime COPY command
RUN mkdir -p /build/codi2/target/release && \
    cp /build/codi2-binary /build/codi2/target/release/codi2 && \
    chmod +x /build/codi2/target/release/codi2

# Binary output: /build/codi2/target/release/codi2 (pre-built, not compiled)

Verification:

ls -lh archive/coditect-v4/codi2/prebuilt/codi2-prebuilt
# Output: -rwxr-xr-x 1 hal hal 16M Oct 27 04:00 codi2-prebuilt

Phase 5: Build #14 Submission (COMPLETED - FAILED)​

Status: FAILED at Stage 6 (npm install -g) Build ID: 33551863-728f-4052-9e1c-3945a472cefe Duration: ~28 minutes (upload 2 min + stages 26 min) Log File: /tmp/cloud-build-14.log

Results by Stage:

  • ✅ Stage 1 (frontend-builder): SUCCESS
  • ✅ Stage 2 (theia-builder): SUCCESS (121s with 66 packages!)
  • ✅ Stage 3 (v5-backend-builder): SUCCESS (with clang fix)
  • ✅ Stage 4 (codi2-builder): SUCCESS (pre-built binary)
  • ✅ Stage 5 (monitor-builder): SUCCESS
  • ❌ Stage 6 (runtime): FAILED at npm install -g

Error Details:

npm error code EEXIST
npm error path /usr/local/bin/yarn
npm error EEXIST: file already exists
npm error File exists: /usr/local/bin/yarn

Root Cause: yarn is pre-installed in node:20-slim base image; npm install -g yarn without --force fails

Fix Applied: Added --force flag to npm install command (dockerfile.combined-fixed:215)

Phase 6: Build #15 Preparation (READY TO SUBMIT)​

Status: Fix applied, ready for submission Change: Added --force to npm install -g command Expected: Should succeed - all previous stages passed

🔜 REMAINING Work​

Immediate: Monitor Build #14 (5-10 min)​

Check build creation:

# Wait for upload to complete, then get build ID
tail -50 /tmp/cloud-build-14.log

# Or check latest build
gcloud builds list --project=serene-voltage-464305-n2 --limit=1

Monitor build progress:

# Replace BUILD_ID with actual ID from logs
gcloud builds log <BUILD_ID> --project=serene-voltage-464305-n2 --stream

Success Criteria:

  • Stage 1 (frontend-builder): ✅ Completes in ~3 min
  • Stage 2 (theia-builder): ✅ Completes in ~8 min (8GB heap)
  • Stage 3 (v5-backend-builder): ✅ Completes in ~2 min (with clang)
  • Stage 4 (codi2-builder): ✅ Completes in ~10 sec (pre-built binary copy)
  • Stage 5 (monitor-builder): ✅ Completes in ~26 sec
  • Stage 6 (runtime): ✅ Completes in ~1 min
  • Overall: SUCCESS in 10-15 minutes

Deploy to GKE (If Build #14 Succeeds) (10 min)​

🧠 Mental Model​

Build Flow (6 Stages)​

Stage 1: frontend-builder (node:20-slim)
  ├─ Install npm dependencies
  ├─ Build Vite frontend
  └─ Output: dist/

Stage 2: theia-builder (node:20-slim)
  ├─ Install theia dependencies (66 packages)
  ├─ Build theia with 8GB heap
  └─ Output: theia-app/lib/, src-gen/, gen-webpack.config.js

Stage 3: v5-backend-builder (rust:1.82-slim)
  ├─ Install FDB + clang + libclang-dev
  ├─ Build Rust backend
  └─ Output: backend/target/release/api-server

Stage 4: codi2-builder (debian:bookworm-slim)
  ├─ SKIP COMPILATION (pre-built binary workaround)
  ├─ Copy pre-built binary
  └─ Output: codi2/target/release/codi2

Stage 5: monitor-builder (rust:1.82-slim)
  ├─ Build file-monitor
  └─ Output: file-monitor/target/release/examples/monitor

Stage 6: runtime (node:20-slim)
  ├─ Install NGINX + dev tools
  ├─ Copy all build artifacts
  ├─ Install global npm packages
  └─ Output: Final Docker image

Why Pre-Built Binary Works​

  • Problem: codi2 V4 source has 30 compilation errors
  • Root Cause: Outdated dependencies, missing tokio-tungstenite
  • Fix Time: 2-4 hours to update cargo.toml, fix trait bounds, borrow checker
  • Workaround: Use pre-built v0.2.0 binary (compiles in 10 sec vs failed compilation)
  • Trade-off: Version locked at v0.2.0, can't rebuild from source (acceptable for MVP)

file-monitor vs codi2​

  • file-monitor (Stage 5): ✅ Compiles successfully from source in 26.5 sec
  • codi2 (Stage 4): ❌ Fails with 30 errors → Pre-built binary workaround
  • Why difference: file-monitor is actively maintained, codi2 is V4 archive code

⚠️ Gotchas & Learnings​

1. Docker Build Cache​

Issue: ENV changes and file deletions don't invalidate Docker cache Example: Adding ENV VITE_API_URL=/api/v5 didn't force rebuild of Vite stage Solution: Modify source files to force cache invalidation

2. Node Memory for theia​

Limit: Default 4GB heap insufficient for 66 @theia packages Solution: NODE_OPTIONS=--max-old-space-size=8192 (8GB) Location: dockerfile.combined-fixed:91 Trade-off: Longer build time (~8 min) but reliable builds

3. libclang for Rust FFI​

Requirement: bindgen crate needs libclang for C bindings (used by foundationdb-sys) Stages Affected:

  • Stage 3 (v5-backend-builder) - ✅ FIXED in Build #12
  • Stage 4 (codi2-builder) - N/A (using pre-built binary) Install: apt-get install clang libclang-dev

4. V4 Archive Code Maintenance​

Status: V4 archive code (archive/coditect-v4/) is NOT actively maintained Implication: Expect compilation issues with Rust crate updates Strategy: Use pre-built binaries or vendor dependencies (Cargo.lock)

5. Cloud Build Upload Time​

Size: 33,074 files, ~2.1 GiB → takes 2-3 minutes to upload Optimization: Consider .gcloudignore to reduce upload (already exists) Impact: Total build time = upload (2-3 min) + build (10-15 min) = 12-18 min
