This deprecates the Event constructor and the ``ts`` parameter of Enqueue()
Instead, versions are introduced that take a detail::MetadataVectorPtr which
can hold the network timestamp metadata and is meant to be allocated by the
caller instead of automatically during Enqueue() or within the Event
constructor.
This also introduces a BifConst ``EventMetadata::add_network_timestamp`` to
opt-in adding network timestamps to events globally. It's disabled by
default as there are not a lot of known use cases that need this.
This test has become flaky after #4295. It hasn't been failing regularly
enough locally to make it approachable. Annotate with
BTEST_BG_RUN_SLEEP=1 to revert to pre #4295 behavior, hopefully
fixing the flakiness as a side-effect.
The new Broker API allows us to provide a custom logger to Broker that
pulls previously unattainable context information out of Broker to put
them into broker.log for users of Zeek.
Since Broker log events happen asynchronously, we cache them in a queue
and use a flare to notify Zeek of activity. Furthermore, the Broker
manager now implements the `ProcessFd` function to avoid unnecessary
polling of the new log queue. As a side effect, data stores are polled
less as well.
Discussed with @J-Gras, calling Broker::publish() within a scheduled
should use the "intended timestamp" implicitly.
This is subtle, but supposedly more expected when running
a pcap replay cluster.
This field isn't required by a worker and it's certainly not used by a
worker to listen on that specific interface. It also isn't required to
be set consistently and its use in-tree limited to the old load-balancing
script.
There's a bif called packet_source() which on a worker will provide
information about the actually used packet source.
Relates to zeek/zeek#2877.
Slightly adapted. I wasn't sure how much guarantee we have around the
change propagation when calling terminate() right after the delete.
Flipped it around a bit, having the worker outlive the manger instead.
This adds compatibility tests for receiving non-timestamped events as
well as providing timestamps via broker websockets.

This has been around since Zeek v4.1, so it was warned about in Zeek 5.0
LTS and we could've removed it with 5.1.
Also removed merge_top_scope() from the zeek::detail namespace, it's
unused now.
Updated the when-aggregates test somehow. I'm not quite sure what had
been tested there :-/
Add configurability of synchronous and journal_mode for SQLite backed
Broker data stores. Setting these to synchronous=normal and journal_mode=wal
can significantly improve throughput at the cost of some durability in
the presence of power loss or OS crash. In the context of Zeek, this is
likely more than acceptable.
Additionally, add integrity_check and failure_mode options to support deleting
and re-opening a corrupted SQLite database at store creation.
Closes#2698
This is just a small optimization on top of what is there.
Add state to Func for tracking if any enabled bodies exist which
allows us to propagate it up to the EventHandler::bool() operator.
In turn, when all bodies of an event's Func have been runtime disabled,
the event itself will not be invoked anymore.
Experiments have shown that this allows runtime toggling of new_event()
without performance impact when disabled. This could enable use-cases
where new_packet() handlers are enabled for a split second once in a
while to either dump or sample raw packet data at runtime.
This exposes Broker's new WebSocket support in Zeek. To enable it,
call `Broker::listen_websocket()`. Zeek will then start listening on
port 9997 for incoming WebSocket connections.
See the Broker documentation for a description of the message format
expected over these WebSocket connections.
* origin/topic/bbannier/spicy:
Add NEWS item for new requirements due to default-enabled Spicy support.
Include headers in binary dir before other headers.
Increase memory in CI.
Add tests for bundled Spicy infrastructure.
Include spicy in build.
Add `bare_mode` bif.
Change test so included plugins can load notice framework.
Do not log function arguments in test.
Broker::NetworkInfo$address is of type string. The Broker::peers() BiF treated
it as an address, which caused ZVal's type validation to flag a
mismatch and abort.
Includes a small tweak to the broker.unpeer test that makes it invoke
Broker::peers(), which breaks in absence of the fix.

GH-1506: Fix Broker unserialization of set/table function indices
Zeek function types are serialized as a broker::vector, but the
unserialization logic for Zeek set/table types that use a function for
as an index incorrectly identified it as a composite-index, which also
use broker::vector, rather than a singleton-index, and makes such
unserialization fail.
A general example where this failure can happen in practice is when
trying to unserialize a connection record for which there's a
Conn::RemovalHook, since that's a set[function], and a specific case of
that is use of the Intel Framework in a Zeek cluster.
Broker::create_master() and Broker::create_clone() now return
a valid value even when there's a failure to open the backend database
(e.g. SQLite filesystem error). In that case, the returned value can
still be passed into other data store operations, but they'll fail
immediately with an error. Broker::is_closed() can now also be used to
determine whether the data store creation calls failed.
