Add file-backed persistence to the internal logWriter so runtime logs
survive service restarts. When internal logging is enabled (CD mode,
no explicit log_path), writes are teed to both the existing in-memory
ring buffer and a rotated file on disk (ctrld.log in the home directory).
File rotation: 5MB max with 1 backup (ctrld.log.1), so max ~10MB on disk.
Log view/send now reads from the persisted files (including backup) to
provide complete history across restarts. Live tail continues to use
the in-memory subscriber mechanism unchanged.
Activation: same conditions as existing internal logging — CD mode only,
no log_path configured. No new config options or dependencies.
- Add newLogReader function with optional ANSI color code stripping
- Implement logReaderNoColor() and logReaderRaw() methods for different use cases
- Add comprehensive documentation for logReader struct and all related methods
- Add extensive test coverage with 16+ test cases covering edge cases
The new functionality allows consumers to choose between raw log data
(with ANSI color codes) or stripped content (without color codes),
making logs more suitable for different processing pipelines and
display environments.
- Add NoticeLevel constant using zapcore.WarnLevel value (1)
- Implement custom level encoders (noticeLevelEncoder, noticeColorLevelEncoder)
- Update Notice() method to use custom level
- Add "notice" case to log level parsing in main.go
- Update encoder configurations to handle NOTICE level properly
- Add comprehensive test (TestNoticeLevel) to verify behavior
The NOTICE level provides visual distinction from INFO and ERROR levels,
with cyan color in development and proper level filtering. When log level
is set to NOTICE, it shows NOTICE and above (WARN, ERROR) while filtering
out DEBUG and INFO messages.
Note: NOTICE and WARN share the same numeric value (1) due to zap's
integer-based level system, so both display as "NOTICE" in logs for
visual consistency.
Usage:
- logger.Notice().Msg("message")
- log_level = "notice" in config
- Supports structured logging with fields
For partial init log data (does not end with a newline), the log writer
discard data after the last newline to make the log prettier, then write
the init end marker. This causes the marker could be written more than
once, since the second overflows will preserve the data which does
include the marker from the first write.
To fix this, ensure that the init end marker is only written once, and
the second overflows will preserve data until the marker instead of the
fixed initial size like the first one.
