Not all supported platforms provide a recent enough cppzmq version,
add a fallback as submodule. cppzmq is a header-only library, so there's
no build step involved.
Also, run the ZAM-bif-tracking test in non-ZAM environments so
failures are caught immediately. There's nothing overly ZAM specific about
running this test.
I'm not sure I like the fact that any new contributor adding a BiF
will need to dig into this... it might be a bit intimidating.
* topic/christian/disconnect-slow-peers:
Bump cluster testsuite to pull in Broker backpressure tests
Expand documentation of Broker events.
Add sleep() BiF.
Add backpressure disconnect notification to cluster.log and via telemetry
Remove unneeded @loads from base/misc/version.zeek
Add Cluster::nodeid_to_node() helper function
Support re-peering with Broker peers that fall behind
Add Zeek-level configurability of Broker slow-peer disconnects
Bump Broker to pull in disconnect feature and infinite-loop fix
No need to namespace Cluster:: functions in their own namespace
* origin/topic/awelzel/license-header-cleanup:
Add missing copyright line to headers and cc files
pre-commit: Add license-header check inspired by Spicy
Add missing "COPYING" in file comments
* origin/topic/vern/CPP-streamlining:
BTest baseline updates for compile-to-C++
mark ZAM regression BTests as not suitable for compile-to-C++
fix for -O gen-C++ maintenance helper to skip BTest intermediary files
introduced simplified initialization for non-standalone -O gen-C++ code tied -O gen-standalone-C++ to use of --optimize-files
streamline generated -O C++ code by relying on per-function profiles rather than aggregate profile
when reporting available/unavailble C++ script bodies, flag those that are skipped
modified AST profiling to mark (and fully skip) non-optimizable functions
modified merge_types() to skip work if given identical types, which also preserves type names (useful for -O gen-C++)
Using network_time to calculate packet lag will produce wrong results
when there is no packet available but network time does not (yet) fall
back to wall clock.
This now picks up additional typical misspellings, but also triggers on
more identifiers we use. I opted for fixing the obvious misspellings and
updated the allowlist for anything else.
* origin/topic/vern/script-opt-uncompilable-AST:
ScriptOpt: Fail compilation if known exprs/stmts is outdated
skip optimization of functions with AST nodes unknown to script optimization
Yes, really. :-) We've hit the need for this on occasion in very specific
settings and always worked around it via ugly nested loops or similars.
This has ample warning that folks normally won't want to use this.
Not sure that ZAM btest should baseline the number of BiFs.
This adds a Broker-specific script to the cluster framework, loaded only when
Zeek is running in cluster mode. It adds logging in cluster.log as well as
telemetry via a metrics counter for Broker-observed backpressure disconnects.
The new zeek_broker_backpressure_disconnects counter, labeled by the neighboring
peer that the reporting node has determined to be unresponsive, counts the
number of unpeerings for this reason.
Here the node "worker" has observed node "proxy" falling behind once:
# HELP zeek_broker_backpressure_disconnects_total Number of Broker peering drops due to a neighbor falling too far behind in message I/O
# TYPE zeek_broker_backpressure_disconnects_total counter
zeek_broker_backpressure_disconnects_total{endpoint="worker",peer="proxy"} 1
Includes small btest baseline update to reflect @load of a new script.
This module is loaded by the telemetry framework, which we're now loading via
the cluster framework, i.e. also in bare mode. The resulting additional
thread (for creating reporter.log) trips up a number of btest baselines.
version.zeek doesn't use any of the string helper functions.
This adds re-peering at the Broker level for peers that Broker decided to
unpeer. We keep this at the Broker level since this behavior is specific to
it (as opposed to other cluster backends).
Includes baseline updates for btests that pick up on the new script's @load.
This analyzer can be used to transport raw stream data for a given
connection to the script layer. For example, adding this analyzer into
the HTTP::upgrade_analyzer or using it to configure a child WebSocket
analyzer allows to get access to the raw stream data in script land
when no more appropriate protocol analyzer is available.
