feat: Add StillHammer TopicTree for O(k) topic routing
Replace O(n×m) regex-based pattern matching with O(k) hierarchical hash map lookup in IntraIOManager. ## Changes **New: StillHammer/topictree library** - Header-only C++17 template library - Zero-copy topic parsing with string_view - Wildcards: `*` (single-level), `.*` (multi-level) - Thread-safe with mutex protection - Comprehensive test suite (10 scenarios) **Modified: IntraIOManager** - Replace RouteEntry vector + regex with TopicTree - Batched logging (every 100 messages) to reduce spam - O(k) lookup where k = topic depth (~3 segments) ## Performance - Before: O(n patterns × m regex ops) per message - After: O(k topic depth) per message - Typical gain: ~33x faster for 100 patterns, depth 3 ## Tests ✅ test_11 (scenarios 1-3): Basic routing, pattern matching, multi-module ✅ test_12: DataNode integration (all 6 tests pass) ⚠️ test_11 (scenario 4+): Batching feature not implemented (out of scope) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

# TopicTree
|
||||
|
||||
**Ultra-fast hierarchical topic matching for pub/sub systems**
|
||||
|
||||
A header-only C++17 library providing O(k) topic matching using hierarchical hash maps, replacing traditional O(n×m) regex-based pattern matching.
|
||||
|
||||
## Features
|
||||
|
||||
- **Blazing Fast**: O(k) lookup where k = topic depth (typically 2-4 segments)
|
||||
- **Zero-copy parsing**: Uses `string_view` for efficient string operations
|
||||
- **Wildcard support**:
|
||||
- Single-level: `player:*:position` matches `player:123:position`
|
||||
- Multi-level: `player:.*` matches all player topics
|
||||
- **Header-only**: No compilation required, just include and use
|
||||
- **Thread-safe**: Mutex-protected operations
|
||||
- **Template-based**: Generic subscriber type support
|
||||
|
||||
## Performance
|
||||
|
||||
Replaces regex-based matching:
|
||||
- **Before**: O(n patterns × m regex operations) - Test ALL patterns for EACH message
|
||||
- **After**: O(k topic depth) - Walk hash tree by segments
|
||||
|
||||
For a typical system with 100 patterns and topics of depth 3:
|
||||
- Regex: ~100 pattern tests per message
|
||||
- TopicTree: ~3 hash lookups per message
|
||||
|
||||
## Usage
|
||||
|
||||
```cpp
|
||||
#include <topictree/TopicTree.h>
|
||||
|
||||
// Create tree with string subscriber IDs
|
||||
topictree::TopicTree<std::string> tree;
|
||||
|
||||
// Register patterns
|
||||
tree.registerSubscriber("player:*:position", "subscriber1");
|
||||
tree.registerSubscriber("player:.*", "subscriber2");
|
||||
tree.registerSubscriber("enemy:001:health", "subscriber3");
|
||||
|
||||
// Find matching subscribers
|
||||
auto matches = tree.findSubscribers("player:123:position");
|
||||
// Returns: ["subscriber1", "subscriber2"]
|
||||
|
||||
// Unregister
|
||||
tree.unregisterSubscriber("player:*:position", "subscriber1");
|
||||
```
|
||||
|
||||
## Pattern Syntax
|
||||
|
||||
- **Separator**: `:` (colon)
|
||||
- **Single wildcard**: `*` - Matches one segment
|
||||
- `player:*:health` matches `player:001:health`, `player:002:health`
|
||||
- Does NOT match `player:001:stats:health` (wrong depth)
|
||||
- **Multi-level wildcard**: `.*` - Matches remaining segments
|
||||
- `player:.*` matches `player:001`, `player:001:health`, `player:001:stats:armor`
|
||||
- Equivalent to "match everything after this point"
|
||||
|
||||
## Integration
|
||||
|
||||
### CMake (via add_subdirectory)
|
||||
|
||||
```cmake
|
||||
add_subdirectory(external/StillHammer/topictree)
|
||||
target_link_libraries(your_target PRIVATE topictree::topictree)
|
||||
```
|
||||
|
||||
### Manual include
|
||||
|
||||
```cmake
|
||||
target_include_directories(your_target PRIVATE
|
||||
external/StillHammer/topictree/include
|
||||
)
|
||||
```
|
||||
|
||||
## Requirements
|
||||
|
||||
- C++17 or later
|
||||
- Standard library only (no external dependencies)
|
||||
|
||||
## Architecture
|
||||
|
||||
```
|
||||
Topic: "player:123:position"
|
||||
Split: ["player", "123", "position"]
|
||||
|
||||
Tree structure:
|
||||
{
|
||||
"player": {
|
||||
"123": {
|
||||
"position": [subscribers],
|
||||
"*": [wildcard_subscribers]
|
||||
},
|
||||
"*": { "position": [wildcard_subscribers] },
|
||||
".*": [multi_level_subscribers]
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Lookup walks the tree level by level, collecting subscribers from:
|
||||
1. Exact matches at each level
|
||||
2. Single wildcards (`*`) at each level
|
||||
3. Multi-level wildcards (`.*`) that match everything below

|
||||
|
||||
## Overview
|
||||
Complete integration test suite for TopicTree ultra-fast topic matching library.
|
||||
|
||||
**Goal**: Validate all features with 10 comprehensive test scenarios covering functionality, performance, thread-safety, and edge cases.
|
||||
|
||||
---
|
||||
|
||||
## Test Scenarios
|
||||
|
||||
### **Scenario 1: Basic Exact Matching**

|
||||
2. Publish `"player:001:position"` → expect `[subscriber1]`
|
||||
3. Publish `"player:002:position"` → expect `[]` (no match)
|
||||
4. Publish `"player:001:health"` → expect `[]` (different topic)
|
||||
|
||||
**Expected**: Only exact matches are returned
|
||||
|
||||
---
|
||||
|
||||
### **Scenario 2: Single Wildcard at Different Positions**

|
||||
---
|
||||
|
||||
### **Scenario 6: Unregister All Patterns for Subscriber**

|
||||
|
||||
**Expected**: Deep hierarchies work correctly with wildcards at multiple levels
|
||||
|
||||
---
|
||||
|
||||
### **Scenario 8: High Volume Performance Test**
|
||||
**Objective**: Validate O(k) performance with large datasets
|
||||
|
||||
**Test Configuration**:
|
||||
- 1000 unique patterns with various wildcard combinations
|
||||
- 10,000 published messages
|
||||
- Measure: avg lookup time, memory usage, correctness
|
||||
|
||||
**Success Criteria**:
|
||||
- Average `findSubscribers()` < 1ms
|
||||
- No memory leaks detected
|
||||
- 100% match accuracy for sampled messages
|
||||
- Performance remains stable (no degradation over time)
|
||||
|
||||
**Benchmark against**: Naive regex O(n×m) implementation
|
||||
|
||||
---
|
||||
|
||||
### **Scenario 9: Thread-Safety - Concurrent Access**
|
||||
**Objective**: Verify thread-safe operations under concurrent load
|
||||
|
||||
**Test Configuration**:
|
||||
- Thread 1: Continuously register new patterns (100/sec)
|
||||
- Thread 2: Continuously unregister patterns (50/sec)
|
||||
- Threads 3-10: Publish messages and verify matches (1000/sec each)
|
||||
- Duration: 10 seconds
|
||||
- Total operations: ~85,000
|
||||
|
||||
**Success Criteria**:
|
||||
- No crashes or deadlocks
|
||||
- No data races (run with ThreadSanitizer)
|
||||
- Results remain consistent and correct
|
||||
- All mutex operations complete successfully
|
||||
|
||||
---
|
||||
|
||||
### **Scenario 10: Edge Cases & Stress Test**
|
||||
**Objective**: Handle unusual inputs and extreme conditions
|
||||
|
||||
**Test Cases**:
|
||||
1. **Empty/Invalid Topics**:
|
||||
- Empty string `""`
|
||||
- Single segment `"player"`
|
||||
- Multiple separators `"a:::b"` (empty segments)
|
||||
|
||||
2. **Minimal Patterns**:
|
||||
- Pattern `"*"` alone
|
||||
- Pattern `".*"` alone
|
||||
- Pattern `"*:*:*"`
|
||||
|
||||
3. **High Subscriber Density**:
|
||||
- 100 different subscribers on same pattern
|
||||
- 1 subscriber on 100 different patterns
|
||||
|
||||
4. **Lifecycle**:
|
||||
- Clear() followed by immediate reuse
|
||||
- Register → Unregister → Re-register same pattern
|
||||
|
||||
5. **Extreme Depth**:
|
||||
- Topics with 20+ segment levels
|
||||
- Patterns with mixed `*` and `.*` at deep levels
|
||||
|
||||
**Expected**: Graceful handling, no crashes, defined behavior for edge cases
|
||||
|
||||

* Example:
