hyper_logger 0.3.0

Composable logging for Dart and Flutter with exact secret redaction, scoped context, file rotation, and cloud-ready JSON for GCP, AWS, and Azure.

Unreleased

0.3.0

Added

• Add HyperLogger.shutdown() for graceful teardown that stays disabled until the next explicit init().
• Add null-safe copyWith transformations to LogEntry and LogMessage.
• Add an ordered, fail-closed sanitizers chain that protects printers and crash-reporting delegates after ordinary interceptors.
• Rebuild RedactingInterceptor around exact structured keys and paths, HTTP field names, URI/form parameter names, JSON decoding, RFC 7468 boundaries, bounded traversal, and configured literal secrets. Literal matching uses a bounded linear-time multi-pattern automaton, with fail-closed limits on matcher construction and sanitized output expansion.
• Add explicit environment-secret collection, application-object encoders, exact wildcard paths, and configurable unknown-value handling.
• Add a standards-backed redaction guide covering exact behavior, limits, performance, testing, and limitations; mirror every cited source in the public Dart API documentation.

Changed

• Skip record allocation, conversion, interceptors, and sanitizers when the current mode and routing flags leave no eligible printer or crash delegate.
• Route native calls directly into the sanitized pipeline; package:logging remains an inbound bridge for third-party records and never broadcasts raw HyperLogger payloads to unrelated root-stream subscribers. Code that relied on observing HyperLogger-native calls through Logger.root.onRecord should use a LogPrinter, interceptor, or sanitizer instead.
• Make LogEntry.message and LogEntry.loggerName canonical across built-in printers and synchronize the LogMessage.message compatibility mirror after every interceptor and sanitizer stage.
• Expose LogMessage.reportToCrashReporting as immutable routing metadata so custom printers can honor skipCrashReporting; delegate dispatch still uses the pipeline's internal routing decision.
• Replace the redactor's sensitiveKeyPattern parameter with exact RedactionPolicy sets. Migration: configure sensitiveKeys, sensitiveHeaderNames, and sensitiveQueryParameters, and pass the new required exact environmentKeys list to fromEnvironment.
• Skip stack-trace inspection and chain construction when the effective methodCount is zero; errorMethodCount remains the error-entry override.

Security

• Ensure sanitizer exceptions and null results drop entries before every configured sink instead of restoring an earlier unsanitized value.
• Revalidate changed candidates to a bounded fixed point so replacement composition cannot synthesize an unchecked JSON, HTTP, URI/form, literal, or final structured-path representation.
• Reject duplicate decoded names in selected environment JSON, cycles, unsupported values when UnknownValueHandling.dropEntry is selected, and all configured resource-limit violations.
• Keep constructor and pipeline diagnostics generic so confidential input is not reflected through errors.

0.2.2+2

• Shrink the published archive from 1.1 MB to 168 KB. The README and docs now reference the preview images by absolute GitHub URL, so pub.dev proxies them from the repository and the PNGs no longer ship to every pub get. The images themselves are back to full 2x resolution.

0.2.2+1

• Restore the README preview images on pub.dev. 0.2.2 excluded assets/ from the published archive.

0.2.2

• Compress assets & add .pubignore.
• LogPrinterPresets.automatic, .human, .terminal, and .ci now forward the full ComposablePrinter tuning surface — methodCount, errorMethodCount, excludePaths, showAsyncGaps, and suppressTypeNames. Previously a preset only took output, so tuning stack-trace depth or frame filtering meant abandoning the preset and composing the decorator list by hand. On automatic the parameters reach the ci/human arms only; the cloud arms emit a raw stackTrace.toString() and have nothing to tune.
• ComposablePrinter.defaultMethodCount — the default frame count (10), exposed so wrappers can mirror it instead of copying the literal.

0.2.1

• Shorten the package description to satisfy pub.dev's character guideline.

0.2.0

Breaking

• RotatingFilePrinter rotation API redesigned. The single rotationConfig: FileRotationConfig.… parameter is replaced by:

  • rotations: List<FileRotation> — a list of rotation rules, each a trigger (FileRotation.size / .interval / .daily / .onStart) crossed with a Cadence (continuous, checked on every write, or onStart, checked once when the file opens). Rules compose as a union (the first to fire rotates), so size and time triggers can now be combined. An empty list (the default) appends forever.
  • retention: FileRetention? — shared archive policy (maxFiles, maxAge, compress). maxBytes/interval now live on the rule; retention knobs moved here.
  • FileRotationConfig is removed.

  Migration: FileRotationConfig.size(maxBytes: N, maxFiles: M, compress: c) → rotations: [FileRotation.size(N)], retention: FileRetention(maxFiles: M, compress: c); FileRotationConfig.interval(interval: D) → rotations: [FileRotation.interval(D)].

Added

• FileRotation.onStart({bool discard}) — rotate (archive) or discard the existing log on every process start, e.g. a fresh server.log per run.
• FileRetention.maxAge — delete rotated archives older than a given duration (age parsed from the archive's filename timestamp), pruned on each rotation alongside maxFiles.

0.1.0

• Initial public release.
