p5-Devel-RingBuffer

Shared memory ring buffers for Perl scripts diagnosis/debug

Provides shared memory structures (using memory mapped files via IPC::Mmap) to be used by diagnostic and debugger applications for Perl scripts (see Devel::STrace). Using XS/C code to maximize performance, creates a set of ring buffers with a configurable number of slots. Each slot includes a field for a line number, a timestamp, and a fully qualified subroutine name. Each ring buffer also includes additional headers and fields to support diagnostic interfaces, e.g., watched expressions, command/response interfaces to the monitored applications, etc.
