* "bro_is_terminating" is now "zeek_is_terminating"
* "bro_version" is now "zeek_version"
The old function names still exist for now, but are deprecated.
For backward compatibility when reading values, we first check
the ZEEK-prefixed value, and if not set, then check the corresponding
BRO-prefixed value.
To be more exact: &encrypt, &mergeable, &rotate_interval, &rotate_size
Also removes no longer used redef-able constants:
log_rotate_interval, log_max_size, log_encryption_key
GH-243
Most of these changes are either cmake-related or plugin-related.
Added a new test "plugins/legacy.zeek" to test that legacy Bro plugins
still work.
Also added a symlink bro-path-dev.in because some legacy Bro packages
won't install without it.
Otherwise, setting Reporter::errors_to_stderr=F causes important
error messages to be lost (and this setting is the default for
ZeekCtl). E.g. now that we terminate if there's errors during
zeek_init, GH-369 shows that the only error message given was
"fatal error: errors occurred while initializing", which is not
helpful in determining the actual issue.
* origin/topic/robin/gh-239:
Undo a change to btest.cfg from a recent commit
Updating submodule.
Fix zeek-wrapper
Update for renaming BroControl to ZeekControl.
Updating submodule.
GH-239: Rename bro to zeek, bro-config to zeek-config, and bro-path-dev to zeek-path-dev.
Note - this compiles, but you cannot run Bro anymore - it crashes
immediately with a 0-pointer access. The reason behind it is that the
required clone functionality does not work anymore.
This commit removed functions/events that have been deprecated in Bro
2.6. It also removes the detection code that checks if the old
communication framework is used (since all the functions that are
checked were removed).
Addresses parts of GH-243
This also installs symlinks from "zeek" and "bro-config" to a wrapper
script that prints a deprecation warning.
The btests pass, but this is still WIP. broctl renaming is still
missing.

Add comments to QueueEvent() and ConnectionEvent()
Add methods to queue events without handler existence check
Cleanup/improve PList usage and Event API
The later simply doesn't work well in conjunction with hostname
literals. i.e. "google.com" (without quotes) needs to be resolved
to a set of addresses at parse-time, so if a user wishes to use a
custom resolver, we need that to be configured independently from
the order in which scripts get parsed. Configuring 'dns_resolver'
via scripting "redef" is clearly dependent on parse order.
Note 'dns_resolver' hasn't been in any release version yet, so
I'm removing it outright, no deprecation. The ZEEK_DNS_RESOLVER
environment variable now serves the original purpose.
* All "Broxygen" usages have been replaced in
code, documentation, filenames, etc.
* Sphinx roles/directives like ":bro:see" are now ":zeek:see"
* The "--broxygen" command-line option is now "--zeexygen"
Added ConnectionEventFast() and QueueEventFast() methods to avoid
redundant event handler existence checks.
It's common practice for caller to already check for event handler
existence before doing all the work of constructing the arguments, so
it's desirable to not have to check for existence again.
E.g. going through ConnectionEvent() means 3 existence checks:
one you do yourself before calling it, one in ConnectionEvent(), and then
another in QueueEvent().
The existence check itself can be more than a few operations sometimes
as it needs to check a few flags that determine if it's enabled, has
a local body, or has any remote receivers in the old comm. system or
has been flagged as something to publish in the new comm. system.
Majority of PLists are now created as automatic/stack objects,
rather than on heap and initialized either with the known-capacity
reserved upfront or directly from an initializer_list (so there's no
wasted slack in the memory that gets allocated for lists containing
a fixed/known number of elements).
Added versions of the ConnectionEvent/QueueEvent methods that take
a val_list by value.
Added a move ctor/assign-operator to Plists to allow passing them
around without having to copy the underlying array of pointers.
* origin/topic/jsiwek/gh-211:
GH-208: change invalid subnet expressions to a runtime error
GH-211: improve consistency of how scripting errors are handled
Removed the 'allow_init_errors' option.
Scripting errors/mistakes now consistently generate a runtime error
which have the behavior of unwinding the call stack all the way out of
the current event handler.
Before, such errors were not treated consistently and either aborted
the process entirely or emitted a message while continuing to execute
subsequent statements without well-defined behavior (possibly causing
a cascade of errors).
The previous behavior also would only unwind out of the current
function (if within a function body), not out the current event
handler, which is especially problematic for functions that return
a value: the caller is essentially left a mess with no way to deal
with it.
This also changes the behavior of the startup/initialization process
to abort if there's errors during bro_init() rather than continue one
to the main run loop. The `allow_init_errors` option may change this
new, default behavior.

Pre-allocate and re-use Vals for bool, int, count, enum and empty string
Preallocate booleans and small counts
I added a tiny change to CompHash to make sure that nothing messes this
up in the future.
This fixes some use-after-free issues in the shutdown order of
various systems: I/O, plugin, logging, and reporter systems may
interact during shutdown if there's errors emitted (or maybe just
still pending) during the shutdown.
Fixes GH-188
This environment variable is now set to listen only on IPv4 loopback
when running unit tests (instead of using the default INADDR_ANY).
This also moves some of the @loads out from init-bare.bro into a new
init-frameworks-and-bifs.bro in order to better support calling BIFs
(like `getenv`) from variable initializations in those particular
frameworks.
