# ShopDB - Claude Code Instructions

## Project Overview

ShopDB is a Classic ASP/VBScript web application for managing manufacturing shop floor infrastructure at GE Aerospace. It tracks machines, PCs, printers, and network devices.

## Technology Stack

- **Backend:** Classic ASP (VBScript)
- **Database:** MySQL 5.6
- **Frontend:** Bootstrap 4.6, jQuery, DataTables
- **Server:** IIS on Windows VM (192.168.122.151:8080)
- **Version Control:** Gitea (localhost:3000)

## Environment Access

**Claude can access (dev environment):**
- Dev MySQL database via Docker (localhost:3306)
- Dev IIS via Windows VM (192.168.122.151:8080)
- Local files and Gitea

**Claude CANNOT access (production):**
- Production IIS server
- Production IIS logs
- Production MySQL database
- Zabbix server (zabbix.compute.geaerospace.net)
- Employee database (wjf_employees) - used by displayprofile.asp (can update code, cannot test)

For production tasks, user must:
- Relay production data/logs to Claude
- Deploy files to production IIS
- Execute database changes on production

## Key Architecture

### Database Schema (Phase 2 - Current)

```
machines table (unified)
├── Equipment (machinetypeid 1-15 and 21-25, pctypeid IS NULL)
├── PCs (machinetypeid 33+, pctypeid IS NOT NULL)
└── Network Devices (machinetypeid 16-20)

printers table (separate)
communications table (all network interfaces)
machinerelationships table (PC↔equipment links)
```

### Key Queries

```sql
-- All PCs
SELECT * FROM machines WHERE pctypeid IS NOT NULL;

-- All Equipment (excludes network devices and PCs)
SELECT * FROM machines WHERE pctypeid IS NULL
  AND machinetypeid NOT IN (16,17,18,19,20) AND machinetypeid < 33;

-- Network devices
SELECT * FROM machines WHERE machinetypeid IN (16,17,18,19,20);
```

## File Structure

```
/home/camp/projects/windows/shopdb/
├── *.asp              # Main ASP pages
├── api.asp            # REST API for PowerShell
├── includes/          # Shared includes (header, footer, sql)
├── js/                # JavaScript files
├── css/               # Stylesheets
├── images/            # Images and icons
├── docs/              # Documentation
├── sql/               # SQL scripts
│   ├── migration_phase1/
│   ├── migration_phase2/
│   └── migration_phase3/
└── logs/              # Application logs
```

## Log Locations

**IIS Logs (Windows VM):** `/home/camp/projects/windows/logs/shopdb/`
- Format: `ex[YYMMDD].log` (e.g., `ex251201.log` for Dec 1, 2025)
- These are synced from the Windows VM via Samba share
- Contains HTTP request logs with status codes and error messages

**API Logs:** Check `logs/` folder in shopdb directory on IIS

## Coding Standards

### ASP/VBScript

1. **Always use parameterized queries** - Never concatenate user input into SQL
2. **Use HTMLEncode for output** - Prevent XSS attacks
3. **Convert text fields to strings** - Use `& ""` to avoid type mismatch errors
4. **Use Option Explicit** - Declare all variables

### Example Safe Query

```vbscript
Dim cmd, rs
Set cmd = Server.CreateObject("ADODB.Command")
cmd.ActiveConnection = objConn
cmd.CommandText = "SELECT * FROM machines WHERE machineid = ?"
cmd.Parameters.Append cmd.CreateParameter("@id", 3, 1, , machineId)
Set rs = cmd.Execute()
```

### Example Safe Output

```vbscript
' Always convert to string and encode
Dim hostname
hostname = ""
If NOT IsNull(rs("hostname")) Then hostname = rs("hostname") & ""
Response.Write(Server.HTMLEncode(hostname))
```

## Common Tasks

### Reading Files
- Main pages are in project root (*.asp)
- Includes are in /includes/
- Check docs/ for documentation

### Making Changes
1. Read the file first
2. Use parameterized queries for any SQL
3. Test on dev server (192.168.122.151:8080)
4. Check IIS logs for errors

### Database Access
```bash
docker exec -it dev-mysql mysql -u root -prootpassword shopdb
```

## Important Notes

### VBScript Limitations
- No `IIf()` function - use If-Then-Else instead
- No Try-Catch - use On Error Resume Next carefully
- Strings are 1-indexed, not 0-indexed

### Column Name Gotchas
- `address` not `ipaddress` in communications table (but printers uses `ipaddress`)
- `defaultgateway` not `gateway` in communications table
- `machinenotes` not `notes` in machines table
- `machineid` not `pcid` for PCs in machines table
- `commconfig` and `dncconfig` tables (not pc_comm_config, pc_dnc_config)

### PC Identification
PCs are in the machines table, identified by:
- `pctypeid IS NOT NULL`
- `machinetypeid IN (33, 34, 35)`

### IIS 401 Error on New ASP Files

**Problem:** When creating new ASP files from scratch, they may return HTTP 200 on the first request but HTTP 401 Unauthorized on all subsequent requests.

**Symptoms:**
- First curl/browser request to new .asp file returns 200
- All following requests return 401 Unauthorized
- Existing files (like printerqrbatch.asp) work fine with consistent 200 responses
- Adding `<%@ Language=VBScript %>` directive alone does NOT fix it

**Solution:** Instead of creating new ASP files from scratch, **copy an existing working ASP file** to the new filename, then modify its contents:

```bash
# DON'T do this (creates file from scratch - will get 401 errors):
# Write tool to create newfile.asp

# DO this instead (copy existing working file):
cp printerqrbatch.asp newfile.asp
# Then use Edit tool to replace the content
```

**Why this works:** The exact root cause is unclear, but appears related to how IIS handles file metadata/permissions for newly created files vs. copied files. Copying preserves whatever attributes IIS needs to serve the file correctly.

**Verified fix:** Files created by copying printerqrbatch.asp consistently return 200 on multiple sequential requests.

## API Endpoints

**Base URL:** `http://192.168.122.151:8080/api.asp`

| Action | Method | Description |
|--------|--------|-------------|
| updateCompleteAsset | POST | PC data collection |
| getDashboardData | GET | Health check |
| updatePrinterMapping | POST | Printer assignments |

## External Integrations

| Page | Purpose |
|------|---------|
| `printerlookup.asp?ip=x.x.x.x` | Zabbix printer lookup by IP/FQDN |

### Zabbix API

- **Config File:** `includes/zabbix.asp`
- **Used For:** Printer supply levels, host monitoring
- **Credentials:** See `secrets.md`

### Gitea (Version Control)

- **URL:** `http://localhost:3000`
- **Repo:** `cproudlock/shopdb`
- **Credentials:** See `secrets.md`

## Testing

### Run Form Tests
After making changes to ASP pages, run the test suite to verify all forms work:
```bash
./tests/test_forms.sh
```

**Tests 41 endpoints:** page loads, add forms, create operations (notifications, equipment, printers, subnets, applications, KB articles, vendors, models, network devices), and API endpoints.

**Cleanup test data:**
```bash
docker exec dev-mysql mysql -u root -prootpassword shopdb -e "DELETE FROM notifications WHERE notification LIKE 'AUTOTEST_%';"
# (similar for other tables - see tests/cleanup_test_data.sql)
```
