- policy/ renamed to scripts/ - By default BROPATH now contains: - scripts/ - scripts/policy - scripts/site - *Nearly* all tests pass. - All of scripts/base/ is loaded by main.cc - Can be disabled by setting $BRO_NO_BASE_SCRIPTS - Scripts in scripts/base/ don't use relative path loading to ease use of BRO_NO_BASE_SCRIPTS (to copy and paste that script). - The scripts in scripts/base/protocols/ only (or soon will only) do logging and state building. - The scripts in scripts/base/frameworks/ add functionality without causing any additional overhead. - All "detection" activity happens through scripts in scripts/policy/. - Communications framework modified temporarily to need an environment variable to actually enable (ENABLE_COMMUNICATION=1) - This is so the communications framework can be loaded as part of the base without causing trouble when it's not needed. - This will be removed once a resolution to ticket #540 is reached.
