* origin/topic/zeke/closures:
Use BROKER_PORT.
Update baseline to reflect new anonymous function naming.
Sync 3rd party.
Allow serialization of closures over Broker.
remove some leftover debug output
Call parent constructor from LambdaExpr.
Table defaults capture closures.
Make ClosureFrame safe & cleanup
Update tests to reflect new error msg.
ClosureFrame takes ownership of its captured vals.
Lambdas selectively clone from the closure.
Add lambda expressions with closures to Zeek.
Plugins that were made using an older skeleton (e.g. from Bro 2.5.x)
may still reference "bro-config.h", "bro-path-dev", or "bro" from the
build tree, so we can simply provide compatibility symlinks/wrappers
for the new files that use "zeek" in their names.
Includes light edit pass.
* origin/topic/zeke/README:
Add plaintext README file.
Fix try.zeek.org link
Improve readability of plaintext.
Tone down HTML and improve development section.
Remove development paragraph.
Update README.
* topic/jsiwek/template-containers-merge:
Fix a potential usage of List::remove_nth(-1)
Change List::remote(const T&) to return a bool
Fix debug build due to old int_list usage within assert
Convert uses of loop_over_list to ranged-for loops
Remove loop_over_queue (as an example for later removing loop_over_list)
Change int_list in CCL.h to be a vector, fix uses of int_list to match
Remove List<> usage from strings.bif
Replace uses of the old Queue/PQueue generation code with new template versions
Convert BaseQueue/Queue/PQueue into templates, including iterator support
Replace uses of the old Dict generation code with new template versions
Convert PDict into template
Replace uses of the old List generation code with new template versions
Convert BaseList/List/PList into templates, including iterator support
* Generally squashed fixups from topic/timw/template-containers
* Add missing include file in List.h: <cassert>
Which was used by the new ShallowClone method and causes multiple enum
declarations/definitions to now crash. Such code is not typically
seen in scripts, but being able to define an enum in both .bif and
.bro files has historically been supported.
Unit tests sometimes use current_time(), which occassionally lands on
a perfect tenth of a second and end up fooling the old canonification
regexp and resulting in output which differs from what's in the
test baseline.
anonymous-functions, their closures, can now be sent over broker.
In order to send an anonymous function the receiver must have parsed
a definition of the functon, but it need not to have been evaluated.
See testing/btest/language/closure-sending.zeek for an example of how
this can be done.
This also sends their closures as well as the closures of regular
functions.
Observed segfault accessing the local static std::map of zeekenv() from
a logging thread, but only in non-debug builds using Apple/Clang
compiler, not in a debug build or GCC. Don't quite get this behavior
since static local variable initialization is supposed to be thread-safe
since C++11, but moving to a global static works and is "more efficient"
anyway since there's no longer any run-time overhead.
