Devel::RingBuffer is a Perl module with shared memory ring buffers for Perl scripts diagnosis/debug. SYNOPSIS # # create ringbuffer # use Devel::RingBuffer; use Devel::RingBuffer::TieInt; my $ringbuf = Devel::RingBuffer->new( File => somefile.trace, Rings => 20, Slots => 20, SlotSize => 300, MessageSize => 256, GlobalSize => 24 * 1024, StopOnCreate => 0, TraceOnCreate => 1) || die "Cant create a ring buffer."; my $ring = $ringbuf->allocate(); 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 ringbuffers with a configurable number of slots. Each slot includes a field for a linenumber, 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/reponse interfaces to the monitored applications, etc..
