package tracing

Release v0.16.0

• Added 64-bit integer and pointer event arguments.

• Added buffer type (src/buffer.mli) that consumes a real-time stream of tracing data and only stores the last N bytes, while preserving global state (e.g. interned strings).

• Changed standard file extension from ".ftf" to ".fxt".

• Moved Tracing_tool_output into its own library.

• Updated trace parser:

  • Support parsing an event stream split over multiple data buffers.

  • Detect, report, and potentially resume incomplete event records.

• Updated trace writer:

  • Removed wrote_bytes from the destination API: writers are now required to update lo when writing to buffers returned by next_buf.

  • Added unix file descriptor destination.

  • Added various utility functions to Writer.Expert.

  • Reserved 17 'dynamic' string interning slots, separate from temp string slots. This region is intended to be used via a ppx frontend.

  • Clarified documentation.
