TraceLog v5.0.0 Release Notes

Release Date: 2019-12-10 // over 4 years ago

  • ➕ Added

    • ➕ Added OutputStreamFormatter protocol to define formatters for use with byte output stream type Writers.
    • ➕ Added TextFormat, an implementation of a OutputStreamFormatter that formats its output based on a supplied template (this is the default formatter for Console and File output).
    • ➕ Added JSONFormat, an implementation of a OutputStreamFormatter that formats its output in standard JSON format.
    • ➕ Added OutputStreamWriter protocol to define types that write byte streams to their output and accept OutputStreamFormatter types to format the output.
    • ➕ Added LogEntry tuple type to Writer defining the formal types that a Writer writes.
    • ➕ Added .buffer option for .async concurrency modes to allow for buffering when the writer is not available to write to its endpoint.
    • ➕ Added protected data monitoring for FileWriter.Strategy.fixed on iOS for use with AsyncConcurrencyModeOption.buffer(writeInterval:strategy:). This allows TraceLog to be started up before protected data is available on iOS.

    Upated

    • Requires Swift 5 for compilation.
    • 🔄 Changed parameters to .async to include options for configuration of the mode (.async(options: Set<AsyncConcurrencyModeOption>) and .async(Writer, options: Set<AsyncConcurrencyModeOption>)).
    • 🔄 Changed Writer protocol log() method to write(_ entry: Writer.LogEntry) to make it easier to process messages by writers and formatters.
    • 🔄 Changed Writer return to Swift.Result<Int, FailedReason> to return instructions for TraceLog for buffering and error recovery.
    • 🔄 Changed ConsoleWriter to accept new OutputStreamFormatter instances allowing you to customize the output log format (default is TextFormat.)
    • 🔄 Changed FileWriter public interface
      • FileWriter now requires the log directory be passed in, removing default value of ./.
      • Removed the fileConfiguration parameter replacing with new strategy enum.
      • It now accepts the new OutputStreamFormatter instances allowing you to customize the output log format (default is TextFormat.)
    • 🔄 Changed FileWriter archive file name date format to "yyyyMMdd-HHmm-ss-SSS" (This was done for maximum compatibility between platforms and can be overridden in the FileConfiguration object passed at init.)
    • TextFormat to add var encoding: String.Encoding { get } requirement.
    • JSONFormat to add var encoding: String.Encoding { get } requirement.
    • 📇 Renamed AsyncOption to AsyncConcurrencyModeOption.
    • 🔄 Changed OutputStreamFormatter, it now requires var encoding: String.Encoding { get }.
    • 📇 Renamed FileWriter.FileStrategy to FileWriter.Strategy.
    • 📇 Renamed FileWriter.Strategy.RotateOption to FileWriter.Strategy.RotationOption.

    ✂ Removed

    • ✂ Removed TraceLogTestHarness module.

    🛠 Fixed

    • 🛠 Fixed logTrace when no trace level is passed. It's now the correct default value of 1 instead of 4 (issue #58).
