Modernize network dialing to use Go's context-aware patterns for better
cancellation support and connection reliability.
Changes:
- Update Go version from 1.24 to 1.25 in go.mod
- Replace ssh.Dial with net.Dialer.DialContext + ssh.NewClientConn
for SSH client connections in serverconnection.go
- Add TCP KeepAlive (30s) for SSH connection health monitoring
- Implement context-aware dialing for SSH agent connections in ssh.go
- Improve error messages to distinguish dial vs SSH handshake failures
- Update AGENTS.md with integration test requirements
Benefits:
- Context cancellation now properly affects connection establishment
- TCP KeepAlive prevents silent connection failures
- Better integration with Go's cancellation patterns
- Improved reliability for distributed systems
All integration tests pass with race detection enabled.

- Add SafeAggregateSet wrapper with mutex protection for concurrent access
- Implement TurboAggregate for direct line processing without channels
- Fix race conditions in turbo mode MapReduce aggregation
- Add proper synchronization for batch processing completion
- Update shutdown sequence to ensure all data is serialized
- Add integration test configuration for high-concurrency scenarios
The turbo mode now correctly handles MapReduce queries with significant
performance improvements while maintaining data integrity and preventing
race conditions during concurrent aggregation.

- Added detailed README.md for internal/profiling package documenting:
- Architecture and core components
- Usage instructions for command-line and programmatic access
- Profile output formats and analysis techniques
- Best practices and troubleshooting guides
- Integration with CI/CD pipelines
- Removed dprofile binary (obsolete, replaced by built-in profiling)
- Cleaned up go.mod to remove unused pprof dependency
The profiling package is now fully documented to help developers
understand and utilize DTail's performance analysis capabilities.

Created a comprehensive profiling framework for dtail commands (dcat, dgrep, dmap)
to analyze CPU usage and memory allocations. The framework now prints all executed
commands to stdout for full transparency.
Key features:
- Integrated Go profiling (CPU, memory, allocations) into all three commands
- Created profile.sh bash script for analyzing pprof profiles
- Added multiple Makefile targets for different profiling scenarios
- Automated profiling scripts with command echoing
- Support for different data sizes (quick, normal, full)
- Special handling for dmap MapReduce format
All profiling commands are now echoed to stdout before execution, making it
easy to understand what the framework is doing and reproduce commands manually.

useful for log file monitorig for example. breaking protocol change which allows to mapreduce aggreate messages containing the default field separator |. add of more unit tests. add logformat mapreduce query keyword. add set mapreduce clause support and support to evaluate built-in functions such as md5sum() and maskdigits().
