# Phase 10 Plan 01: Proxy Pool Core Summary
|
||||
|
||||
**Proxy pool infrastructure with YAML configuration, round-robin rotation, and backward compatible environment variable fallback**
|
||||
|
||||
## Performance
|
||||
|
||||
- **Duration:** 3 min
|
||||
- **Started:** 2026-03-18T08:37:15Z
|
||||
- **Completed:** 2026-03-18T08:40:28Z
|
||||
- **Tasks:** 2
|
||||
- **Files modified:** 2
|
||||
|
||||
## Accomplishments
|
||||
- ProxyPool class manages multiple proxies with round-robin rotation
|
||||
- ProxyEntry tracks proxy state including failures and availability
|
||||
- YAML configuration loading from ~/.kb_proxies.yaml
|
||||
- Backward compatible HTTPS_PROXY/HTTP_PROXY environment variable loading
|
||||
- Lazy cooldown recovery check without background threads
|
||||
|
||||
## Task Commits
|
||||
|
||||
Each task was committed atomically:
|
||||
|
||||
1. **Task 0: 创建测试脚手架** - `bcf1a88` (test)
|
||||
2. **Task 1: 实现 ProxyEntry + ProxyPool 核心类** - `c58a7d0` (feat)
|
||||
|
||||
_Note: TDD tasks have multiple commits (test → feat)_
|
||||
|
||||
## Files Created/Modified
|
||||
- `kb_workflow/crawler/proxy_pool.py` - ProxyPool, ProxyEntry, ProxyPoolConfig classes
|
||||
- `tests/test_crawler/test_proxy_pool.py` - 11 unit tests for proxy pool functionality
|
||||
|
||||
## Decisions Made
|
||||
- Use index pointer (`_current_index`) for round-robin instead of `itertools.cycle` for better testability and predictable behavior
|
||||
- Lazy cooldown check in `get_next_proxy()` instead of background timer to avoid threading complexity
|
||||
- When all proxies are unavailable, fallback to first proxy instead of returning None
|
||||
|
||||
## Deviations from Plan
|
||||
|
||||
None - plan executed exactly as written.
|
||||
|
||||
## Issues Encountered
|
||||
None - implementation followed RESEARCH.md pattern examples directly.
|
||||
|
||||
## User Setup Required
|
||||
|
||||
None - no external service configuration required.
|
||||
|
||||
## Next Phase Readiness
|
||||
- Proxy pool core functionality complete
|
||||
- Ready for Plan 02 (health check and failure recovery)
|
||||
- Integration with ZhihuCrawler pending
