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 :-/
This started with reverting commit 52cd02173d
and then rewriting it to be per handler rather than handler identifier
and adding support for hooks as well as adding implicit module groups.
Mostly: Do not instantiate variables within for loops and allow
reusing differently typed blanks which previously wasn't possible.
This may be missing some corner-cases, but the added tests seem
to work as expected and nothing else fell apart it seems.
Avoid the issue outlined in #2289 where the @if or @else is taken as the
statement of an `if`, `for` or `while` by rejecting such constructs.
Effectively this means the following scripts are now rejected:
# Print's "cond true" with Zeek 5.0 even though the `if ( F )`
# should be in effect.
if ( F )
@if ( T )
print "cond true";
@else
print "cond false";
@endif
or
# Print's "hello" once with Zeek 5.0
local v = vector( 1, 2, 3 );
for ( i in v )
@if ( T )
print("hello")
@endif
To make above work as intended, additional braces can be used.
if ( T )
{
@if ( cond )
print "cond true";
@else
print "cond false";
@endif
}
for ( i in v )
{
@if ( T )
print("hello")
@endif
}
I ran into wanting to iterate over just the values of a vector and wondering
whether that could just work.
This adds support for the following, where v will be value of vec[i].
local vec = vector("zero", "one", "two");
for ( i, v in vec )
print i, v;

This enables locating the headers within the install-tree using the
dirs provided by `zeek-config --include_dir`.
To enable locating these headers within the build-tree, this change also
creates a 'build/src/include/zeek -> ..' symlink.
