# 06 — Parsers

## Framework

### Registration

Each vendor parser registers itself via Go's `init()` side-effect import pattern.

All registrations are collected in `internal/parser/vendors/vendors.go`:
```go
import (
    _ "git.mchus.pro/mchus/logpile/internal/parser/vendors/inspur"
    _ "git.mchus.pro/mchus/logpile/internal/parser/vendors/dell"
    // etc.
)
```

### VendorParser interface

```go
type VendorParser interface {
    Name() string                                // human-readable name
    Vendor() string                              // vendor identifier string
    Version() string                             // parser version (increment on logic changes)
    Detect(files []ExtractedFile) int            // confidence 0–100
    Parse(files []ExtractedFile) (*models.AnalysisResult, error)
}
```

### Selection logic

All registered parsers run `Detect()` against the uploaded archive's file list.
The parser with the **highest confidence score** is selected.
Multiple parsers may return >0; only the top scorer is used.

### Adding a new vendor parser

1. `mkdir -p internal/parser/vendors/VENDORNAME`
2. Copy `internal/parser/vendors/template/parser.go.template` as starting point.
3. Implement `Detect()` and `Parse()`.
4. Add blank import to `vendors/vendors.go`.

`Detect()` tips:
- Look for unique filenames or directory names.
- Check file content for vendor-specific markers.
- Return 70+ only when confident; return 0 if clearly not a match.

### Parser versioning

Each parser file contains a `parserVersion` constant.
Increment the version whenever parsing logic changes — this helps trace which
version produced a given result.

## Parser data quality rules

### FirmwareInfo — system-level only

`Hardware.Firmware` must contain **only system-level firmware**: BIOS, BMC/iDRAC,
Lifecycle Controller, CPLD, storage controllers, BOSS adapters.

**Device-bound firmware** (NIC, GPU, PSU, disk, backplane) **must NOT be added to
`Hardware.Firmware`**. It belongs to the device's own `Firmware` field and is already
present there. Duplicating it in `Hardware.Firmware` causes double entries in Reanimator.

The Reanimator exporter filters by `FirmwareInfo.DeviceName` prefix and by
`FirmwareInfo.Description` (FQDD prefix). Parsers must cooperate:

- Store the device's FQDD (or equivalent slot identifier) in `FirmwareInfo.Description`
  for all firmware entries that come from a per-device inventory source (e.g. Dell
  `DCIM_SoftwareIdentity`).
- FQDD prefixes that are device-bound: `NIC.`, `PSU.`, `Disk.`, `RAID.Backplane.`, `GPU.`

### NIC/device model names — strip embedded MAC addresses

Some vendors (confirmed: Dell TSR) embed the MAC address in the device model name field,
e.g. `ProductName = "NVIDIA ConnectX-6 Lx 2x 25G SFP28 OCP3.0 SFF - C4:70:BD:DB:56:08"`.

**Rule:** Strip any ` - XX:XX:XX:XX:XX:XX` suffix from model/name strings before storing
them in `FirmwareInfo.DeviceName`, `NetworkAdapter.Model`, or any other model field.

Use `nicMACInModelRE` (defined in the Dell parser) or an equivalent regex:
```
\s+-\s+([0-9A-Fa-f]{2}:){5}[0-9A-Fa-f]{2}$
```

This applies to **all** string fields used as device names or model identifiers.

### PCI device name enrichment via pci.ids

If a PCIe device, GPU, NIC, or any hardware component has a `vendor_id` + `device_id`
but its model/name field is **empty or generic** (e.g. blank, equals the description,
or is just a raw hex ID), the parser **must** attempt to resolve the human-readable
model name from the embedded `pci.ids` database before storing the result.

**Rule:** When `Model` (or equivalent name field) is empty and both `VendorID` and
`DeviceID` are non-zero, call the pciids lookup and use the result as the model name.

```go
// Example pattern — use in any parser that handles PCIe/GPU/NIC devices:
if strings.TrimSpace(device.Model) == "" && device.VendorID != 0 && device.DeviceID != 0 {
    if name := pciids.Lookup(device.VendorID, device.DeviceID); name != "" {
        device.Model = name
    }
}
```

This rule applies to all vendor parsers. The pciids package is available at
`internal/parser/vendors/pciids`. See ADL-005 for the rationale.

**Do not hardcode model name strings.** If a device is unknown today, it will be
resolved automatically once `pci.ids` is updated.

## Vendor parsers

### Inspur / Kaytus (`inspur`)

**Status:** Ready. Tested on KR4268X2 (onekeylog format).

**Archive format:** `.tar.gz` onekeylog

**Primary source files:**

| File | Content |
|------|---------|

- NIC: firmware, serial, part number (when text logs leave fields empty)

**Module structure:**
```
inspur/
  parser.go   — main parser + registration
  sdr.go      — sensor/SDR parsing
  fru.go      — FRU serial parsing

### Generic text fallback (`generic`)

**Status:** Ready (v1.0.0).

**Confidence:** 15 (lowest — only matches if no other parser scores higher)

**Purpose:** Fallback for any text file or single `.gz` file not matching a specific vendor.

**Behavior:**
- If filename matches `nvidia-bug-report-*.log.gz`: extracts driver version and GPU list.
- Otherwise: confirms file is text (not binary) and records a basic "Text File" event.
