While we support initializing records via coercion from an expression
list, e.g.,
local x: X = [$x1=1, $x2=2];
this can sometimes obscure the code to readers, e.g., when assigning to
value declared and typed elsewhere. The language runtime has a similar
overhead since instead of just constructing a known type it needs to
check at runtime that the coercion from the expression list is valid;
this can be slower than just writing the readible code in the first
place, see #4559.
With this patch we use explicit construction, e.g.,
local x = X($x1=1, $x2=2);
- On-demand access to sumstats results through "return from"
functions named SumStats::request and Sumstats::request_key.
Both functions are tested in standalone and clustered modes.
- $name field has returned to SumStats which simplifies cluster
code and makes the on-demand access stuff possible.
- Clustered results can only be collected for 1 minute from their
time of creation now instead of time of last read.
- Thresholds use doubles instead of counts everywhere now.
- Calculation dependency resolution occurs at start up time now
instead of doing it at observation time which provide a minor
cpu performance improvement. A new plugin registration mechanism
was created to support this change.
- AppStats now has a minimal doc string and is broken into hook-based
plugins.
- AppStats and traceroute detection added to local.bro
- New, expanded API.
- Calculations moved into plugins.
- Scripts using measurement framework ported.
- Updated the script-land queue implementation to make it more generic.
-
- The feature was primarily added to allow the value to be
modified for cluster based intermediate threshold checks
without requiring the user to write the metrics filter
differently for cluster consideration. It's also a nice
way to calculate some related information to the metric
without accidently applying thresholds to that value.
- Fixed a few small bugs in ftp detect-bruteforcing script
and adapted it to the new threshold value selection feature.
- 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.
