Historically, a 'when' condition performed an AST-traversal to locate any index-expressions like `x[9]` and evaluated them so that it could register the associated value as something for which it needs to receive "modification" notifications. Evaluating arbitrary expressions during an AST-traversal like that ignores the typical order-of-evaluation/short-circuiting you'd expect if the condition was evaluated normally, from its root expression. Now, a new subclass of IndexExpr is used to keep track of all IndexExpr results in the context of evaluating a 'when' condition without having to do a secondary AST-traversal-and-eval. i.e. the first evaluation of the full 'when' condition follows the typical expression-evaluation semantics (as always), but additionally now captures all the values a Trigger needs to monitor for modifications. |

This directory contains suites for testing for Zeek's correct
operation:
btest/
An ever-growing set of small unit tests testing Zeek's
functionality.
external/
A framework for downloading additional test sets that run more
complex Zeek configuration on larger traces files. Due to their
size, these are not included directly. See the README for more
information.
scripts/
Helpers scripts used by some tests.
