This is just for playing around for the moment. It tries to address
the situation that a bif creates a C-level data structure that is then
to be manipulated with further bifs (but not with other script-level
operators). There are two problems with that:
- We don't have a type at the script-level to represent the
created data structure.
- We can't just pass C-level pointers around (say, via "any")
because then garbage collection wouldn't clean up after us.
This patch allows to wrap such a pointer with a record:
type Foo = record {
opaque: any;
};
The bifs simply pass around instances of this record, while internally
storing a C pointer to the data structure instance in its only field.
Internally, "opaque" is an instance of a new Val-derived class
OpaqueVal. It gets cleaned up via ref-counting as usual and deletes
the C data structure automatically when done.

This directory contains some of the suites for testing for Bro's correct operation: istate/ Tests Bro's independent state facilities. These include persistent values and inter-process event/value communication. (Note that the Bro developers maintain a separate test suite for Bro's trace analysis capabilities. This is kept private as it uses sensitive raw traces for input.)
