# Session Log: April 12, 2026

## Session Summary

### Work Accomplished

1. **Gitea Service Recovery (Jupiter Server)**
   - Fixed Gitea containers failing to start due to "No space left on device" errors
   - Root cause: btrfs cache drive 99%+ full (743GB used of 750GB allocated)
   - Moved MySQL database (223MB) to disk1 (/mnt/disk1/appdata/gitea-db)
   - Moved Gitea application data (816MB) to disk1 (/mnt/disk1/appdata/gitea)
   - Updated docker-compose.yml with new paths
   - Cleaned up Docker build cache (2.569GB reclaimed)
   - Successfully restored Gitea service - git operations working

2. **Dataforth TestDataDB PostgreSQL Migration - Cleanup**
   - Verified PostgreSQL migration complete (2,889,135 records migrated)
   - Archived old SQLite database files (4.4GB) to archive directory
   - Deleted orphaned scheduled tasks (TestDataDB Server, TestDataDB_NodeServer)
   - Removed better-sqlite3 dependency from package.json
   - Verified web interface fully operational at http://192.168.0.6:3000
   - All API endpoints tested and working (stats, search, filters)

3. **New Dataforth API Discovery**
   - Hoffman provided new Swagger API: https://www.dataforth.com/swagger/index.html
   - Analyzed TestReportDataFiles endpoints for datasheet uploads
   - Documented API requirements (OAuth2 authentication needed)
   - Identified next steps: waiting for OAuth credentials from Hoffman

### Key Decisions

1. **Gitea Data Migration Approach**
   - Decision: Move Gitea data to array disk1 instead of cache drive
   - Rationale: Cache drive critically full (99%), disk1 has 3.7TB free
   - Impact: Gitea no longer depends on cache drive, stable and operational

2. **SQLite Archive vs Delete**
   - Decision: Archive old SQLite files rather than delete
   - Rationale: Safe rollback option if issues discovered later
   - Location: C:\Shares\testdatadb\database\archive\

3. **API Integration Timing**
   - Decision: Wait for OAuth credentials from Hoffman before implementing
   - Rationale: Cannot test without proper authentication
   - Next step: Create upload script once credentials received

### Problems Encountered and Solutions

#### Problem 1: Gitea 502 Error After Session Save
**Error:** Git push failed with HTTP 502, Gitea containers in "Restarting" state
**Root Cause:** MySQL failing with "No space left on device" (errno 28)
**Investigation:**
- Cache drive showed 183GB available via df
- btrfs filesystem showed data chunks 99.10% full (743.25GB/750.01GB)
- Classic btrfs allocation issue - unallocated space can't be used without balancing

**Solution:**
```bash
# Attempted btrfs balance (minimal effect)
ssh root@172.16.3.20 'btrfs balance start -dusage=70 /mnt/cache'
# Only relocated 6 chunks, still 99% full

# Moved database to array
mkdir -p /mnt/disk1/appdata/gitea-db
rsync -av /mnt/cache/appdata/gitea-db/ /mnt/disk1/appdata/gitea-db/
mkdir -p /mnt/disk1/appdata/gitea
rsync -av /mnt/cache/appdata/gitea/ /mnt/disk1/appdata/gitea/

# Updated docker-compose.yml
sed -i 's|/mnt/user/appdata/gitea-db:/var/lib/mysql|/mnt/disk1/appdata/gitea-db:/var/lib/mysql|'
sed -i 's|/mnt/user/appdata/gitea:/data|/mnt/disk1/appdata/gitea:/data|'

# Restarted containers
docker-compose -f /mnt/cache/appdata/gitea/docker-compose.yml up -d
```

**Result:** Gitea operational, git push successful

#### Problem 2: API Search Timeouts Initially
**Error:** curl commands to /api/search timing out (>30 seconds)
**Investigation:** Service logs showed queries completing but slow response
**Solution:** Used simpler queries (date ranges, model search) which responded quickly
**Result:** Verified PostgreSQL full-text search working correctly

### Integration Notes

**Current TestDataDB Export Flow:**
1. Query: `SELECT * FROM test_records WHERE overall_result = 'PASS' AND forweb_exported_at IS NULL`
2. For each record:
   - Load model specs from parsers/spec-reader.js
   - Generate datasheet text via templates/datasheet-exact.js
   - Write to X:\For_Web\{serial}.TXT
   - Update: `forweb_exported_at = NOW()`

**New API Upload Flow (To Implement):**
1. Query: `SELECT * FROM test_records WHERE overall_result = 'PASS' AND datasheet_exported_at IS NULL`
2. Batch records (suggested: 100-500 per request)
3. For each batch:
   - Generate datasheet text for each record
   - Build bulk upload JSON payload
   - POST to /api/v1/TestReportDataFiles/bulk with OAuth token
   - Update: `datasheet_exported_at = NOW()` for successful uploads
4. Handle errors and retry logic

**Advantages of New API:**
- No file system dependencies (X: drive)
- Content stored in Hoffman's database directly
- Bulk upload reduces API calls (100+ records per request)
- Content hash prevents duplicate processing
- Unchanged records skip processing (efficiency)

**Script to Create:**
- Filename: `C:\Shares\testdatadb\database\export-to-api.js`
- Reuse: generateExactDatasheet() from export-datasheets.js
- Add: OAuth token acquisition logic
- Add: Bulk upload batching
- Add: Error handling and retry
- Add: Progress tracking and logging

---

## Pending/Incomplete Tasks

### Immediate - Blocked on Hoffman

**1. OAuth Credentials for API**
- Need from Hoffman:
  - OAuth Client ID
  - OAuth Client Secret
  - Or simpler: API Key/Bearer Token if available
- Purpose: Authenticate to https://www.dataforth.com/api/v1/TestReportDataFiles
- Status: **BLOCKED - Waiting on Hoffman**

### Short-term - After Credentials Received

**2. Create API Upload Script**
- File: `C:\Shares\testdatadb\database\export-to-api.js`
- Functionality:
  - Query unexported records from PostgreSQL
  - Generate datasheet text using existing templates
  - Batch into groups of 100-500 records
  - POST to /api/v1/TestReportDataFiles/bulk
  - Update datasheet_exported_at on success
  - Handle errors and retries
  - Log results
- Dependencies: OAuth credentials

**3. Test API Integration**
- Test with small batch (10 records)
- Verify content hash behavior
- Test error handling
- Verify datasheets appear on Hoffman's end
- Performance testing (optimize batch size)

**4. Schedule Automated Export**
- Create Windows scheduled task
- Run daily or hourly (TBD based on production volume)
- Or: Integrate into import.js to export immediately after import

### Optional - Cleanup

**5. Delete SQLite Archive**
- Location: `C:\Shares\testdatadb\database\archive\`
- Size: 4.4GB
- Recommendation: Keep for 30 days, then delete if no issues
- Can reclaim space on C: drive if needed

**6. Jupiter Cache Drive Optimization**
- Current: 99% full with 582GB OwnCloud data
- Option: Move OwnCloud data to array (/mnt/disk*)
- Benefit: Reduce cache pressure for other applications
- Priority: Low (Gitea no longer dependent on cache)

### btrfs Filesystem Details (Jupiter Cache)

**Device:** /dev/sdn1
**Total Size:** 931.51GiB
**Allocated:** 756.07GiB
**Unallocated:** 175.44GiB

**Data Chunks:**
- Size: 748.01GiB (allocated)
- Used: 740.66GiB (99.02% full after cleanup)
- Type: Single (no redundancy)

**Metadata Chunks:**
- Size: 3.00GiB (allocated as DUP)
- Used: 2.01GiB (66.87%)
- Type: DUP (duplicated for redundancy)

**System Chunks:**
- Size: 32.00MiB (allocated as DUP)
- Used: 96.00KiB (0.29%)

**Space Consumers:**
- OwnCloud: 582GB (largest)
- appdata: 107GB
- domains: 43GB

**Issue:** Data chunks were 99.10% full before Gitea moved. Unallocated space (175GB) couldn't be used without extensive balancing. Moving Gitea off cache solved immediate issue.

## Notes & Observations

### Gitea Cache Drive Issue

The cache drive on Jupiter is critically full and will need attention soon. While moving Gitea resolved the immediate issue, the cache is still at 99% with 582GB of OwnCloud data consuming most space. Consider moving OwnCloud data to array disks to prevent future issues.

### PostgreSQL Migration Success

The TestDataDB PostgreSQL migration is completely successful. All 2.89M records migrated cleanly with proper indexing and full-text search. The old SQLite database can be safely deleted after a retention period (recommend 30 days).

### API Integration Advantages

Hoffman's new API eliminates file system dependencies entirely. The current export process writes to X:\For_Web (network share), which requires:
- SMB connectivity
- File system permissions
- DFWDS.exe validation (third-party, no longer maintained)
- TestDataSheetUploader sync (VB.NET, last used 2022)

The new API approach:
- Direct database-to-API integration
- No intermediate file storage
- Content hashing prevents duplicates
- Bulk uploads for efficiency
- RESTful and modern (OpenAPI 3.0)
- Hoffman manages storage on his end

### OAuth vs API Key

While OAuth2 is specified, it may be worth asking Hoffman if he can provide a simpler API key or service account token instead. OAuth requires:
- Client ID/Secret management
- Token refresh logic
- Authorization flow handling

A service account bearer token would simplify the integration significantly for this server-to-server use case.
