Documented Logxide's feature coverage against Python's standard logging module to help users determine compatibility for their use cases.

Analysis Scope

Compared Logxide implementation against all Python logging components:

  • Core logging functions (basicConfig, getLogger, debug/info/error, etc.)
  • Logger methods and attributes (setLevel, addHandler, propagate, etc.)
  • All 15 handler classes from logging/logging.handlers
  • Formatter styles and methods
  • Filter mechanism
  • LogRecord attributes
  • Advanced features (hierarchy, inheritance, thread safety, etc.)

Key Findings

Core Features: ~78-83% coverage

  • ✅ 100% support: Core API, Logger methods, Formatters, Filters, LogRecord, hierarchy, thread safety
  • ⚠️ Partial: basicConfig options (77%), advanced features (70%)
  • ❌ Missing: 9/15 handlers (TimedRotating, Socket, Datagram, SysLog, SMTP, NTEventLog, Buffering, Queue, WatchedFile)

Logxide-exclusive features: OTLPHandler, 2.7x faster I/O, Sentry integration

Documentation Added

  • PYTHON_LOGGING_FEATURE_COMPARISON.md - Detailed feature matrix with support status
  • FEATURE_ANALYSIS_SUMMARY.md / FEATURE_ANALYSIS_SUMMARY_KR.md - Usage recommendations
  • Updated README.md with documentation links

Usage Guidance

Use Logxide when: High performance needed, basic file/console/HTTP logging, modern stack (OTLP, Sentry)

Use stdlib logging when: Network handlers required (SysLog, Socket, SMTP), time-based rotation, QueueHandler for multiprocessing, LoggerAdapter

Original prompt

Logxide 레포가 python std logging 이 제공하는 기능을 모두 제공하는지 확인해줘
Drop in replacement인지를 물어보는것 아님

## Benchmark Results

Comprehensive file I/O performance comparison on Python 3.12.12:

- **LogXide**: 428,221 ops/sec (FASTEST)
- **Picologging**: 363,422 ops/sec (-15%)
- **Python logging**: 155,366 ops/sec (-64%)
- **Structlog**: 174,164 ops/sec (-59%)

### Key Findings

- **17.8% faster** than Picologging (C-based)
- **2.76x faster** than standard Python logging
- **2.46x faster** than Structlog

### Changes

- Add BENCHMARK_SUMMARY.md with complete comparison
- Update README.md with Python 3.12 benchmark table
- Enhance benchmark/compare_loggers.py with stdlib support
- Add subprocess-based testing for Python logging
- Include comprehensive docstrings and comments
- Archive old benchmark files
- Update .gitignore for benchmark data management

### Migration Benefits

Applications using standard library logging can achieve **2.7x performance
improvement** by changing one import line:

```python
# Before
import logging

# After
from logxide import logging
```

Zero code changes required - drop-in replacement with massive performance gains.

Test configuration:
- Platform: macOS ARM64
- Python: 3.12.12
- Iterations: 100,000 per test
- Real file I/O with FileHandler
- Remove unused dependencies and imports (tokio, crossbeam, tracing,
  lazy_static)
- Remove unused static variables and clean up 25+ compiler warnings
- Remove async/Tokio runtime architecture; switch to direct handler
  calls for performance
- FileHandler now flushes after each write for reliable logging
- Fix unused variable and mut warnings in handler registration
- Add `python-handlers` feature flag; PythonHandler disabled by default
- Update README and documentation to clarify handler support and
  architecture
- Update benchmarks and compatibility tests to reflect Rust-native
  handler usage
- Remove deprecated/unsupported handler tests and files
- Bump version to 0.1.3 in all metadata files
- Fix all ruff lint errors (import sorting, unused variables, bare except, etc.)
- Apply ruff formatting to 12 files
- Add --locked flag to cargo-audit installation to fix version compatibility
- Fix StreamHandler self-reference in module_system.py by using alias
- Fix _effective_level type annotation in fast_logger_wrapper.py
  (initialize as int=0 instead of None to avoid type narrowing issues)
- Apply cargo fmt to fix Rust code formatting
- Add #[allow(deprecated)] to PythonHandler impl blocks to suppress
  deprecated warnings in clippy with -D warnings
- Add wrapped_setLevel to sync level changes from std logger to Rust PyLogger
- Add Filter class, captureWarnings, makeLogRecord and other missing compat functions
- Add module-level logging functions (info, debug, warning, etc.)
- Clean up ~250 lines of dead code in module_system.py
- Remove debug prints from Rust code
- Add BufferedHTTPHandler test with authentication headers
- Transform Callback: Python callable for custom JSON transformation
- Global Context: Auto-inject metadata (app_name, env) to all records
- Extra Fields: Support complex types (int, dict, list) via serde_json::Value
- Manual Flush: Explicit buffer flush and graceful shutdown
- Dynamic Context Provider: Callable executed per batch for dynamic fields
- Error Callback: Custom handling for HTTP failures
- Add PercentStyle, StrFormatStyle, StringTemplateStyle classes (pytest requires these)
- Fix StreamHandler.emit() to actually write to stream (was no-op)
- Make LogRecord/Handler subclassable via pure Python wrappers
- Add LOGXIDE_DISABLE_AUTO_INSTALL env var to opt-out of auto-patching
- Add _STYLES dict and BASIC_FORMAT constant for full logging compat
LogRecord stays as Rust type (not subclassable) - performance over compatibility.
Auto-patching is intended behavior, no opt-out needed.
- Update README to clearly state performance over compatibility
- Add compatibility table for supported/unsupported features
- Add third-party library compatibility matrix
- Document that LogRecord/Logger are not subclassable (Rust types)
…ndler to HTTPHandler

- Rename BufferedHTTPHandler to HTTPHandler for consistency with other handlers
- Add OTLPHandler implementing OpenTelemetry Protocol (OTLP) v1 for logs
- Add prost and opentelemetry-proto dependencies for protobuf serialization
- Update documentation and tests to reflect naming changes
…s, and CI environment

- Switch opentelemetry-proto to 'tonic' feature to use pre-generated code and avoid protoc dependency
- Fix clippy warnings in OTLPHandler (use std::mem::take instead of drain/collect)
- Update CI configuration to include PYO3_USE_ABI3_FORWARD_COMPATIBILITY=1 for Python 3.14
- Fix compatibility issues with Sentry SDK by adding level argument to Handler.__init__ and callHandlers to PyLogger
- Restore _auto_configure_sentry in module_system.py for test compatibility
…ibility

- Implement callback logic in emit_record to call Python handlers
- Allow registration of non-Rust handlers to keep compatibility with pytest's caplog and Sentry
- Ensure zero performance impact when no Python handlers are registered (cheap empty check)
… mechanism

- Fix LogRecord creation for Python compatibility
- Enable local and global Python handler support in PyLogger
- Verified end-to-end integration with standard Python logging handlers
… log capture in tests

- Implement MemoryHandler in Rust to avoid GIL bottlenecks during tests
- Expose MemoryHandler to Python for easy integration with pytest
- Achieved performance of over 170k logs/sec during capture
