# Session 07: Protocol Parser
|
||
|
||
## Summary
|
||
|
||
The NATS protocol parser — parses raw bytes from client connections into protocol operations (PUB, SUB, UNSUB, CONNECT, etc.). Extremely performance-critical.
|
||
|
||
## Scope
|
||
|
||
| Go File | Features | Feature IDs | Go LOC |
|
||
|---------|----------|-------------|--------|
|
||
| server/parser.go | 5 | 2588–2592 | 1,165 |
|
||
| **Total** | **5** | | **1,165** |
|
||
|
||
## .NET Classes
|
||
|
||
- `ProtocolParser` — state-machine parser for NATS wire protocol
|
||
- `ClientConnection` (partial — parser-related methods only)
|
||
|
||
## Test Files
|
||
|
||
| Test File | Tests | Test IDs |
|
||
|-----------|-------|----------|
|
||
| server/parser_test.go | 17 | 2598–2614 |
|
||
| **Total** | **17** | |
|
||
|
||
## Dependencies
|
||
|
||
- Session 01 (Foundation Types — protocol constants, errors)
|
||
|
||
## .NET Target Location
|
||
|
||
- `dotnet/src/ZB.MOM.NatsNet.Server/Protocol/`
|
||
|
||
## Notes
|
||
|
||
- Only 5 features but 1,165 LOC — these are large state-machine functions
|
||
- Must use `ReadOnlySpan<byte>` and avoid allocations in the parse loop
|
||
- The parser is called for every byte received — benchmark after porting
|
||
- Consider using `System.IO.Pipelines` for buffer management
