Copying an &ordered table or set would result in a copy that is not ordered.
This seems rather surprising behavior, so propagate the &ordered attribute.
Closes#2793
Mostly for consistency with &default, &expire_func and other attributes
being propagated through a copy(). Seems this was just missed during
the implementation and/or was never tested for.
The added test cases around function/event invocations report the
following flurry of errors when only the first one is relevant and
actionable. There's little use in reporting a mismatch with "error".
Squelch them.
error in <...>/function-invoke-mismatch-error.zeek, line 8: identifier not defined: MyEnumTypo
error in <...>/function-invoke-mismatch-error.zeek, line 12 and error: type mismatch (M::MY_ENUM_A and error)
error in <...>/function-invoke-mismatch-error.zeek, line 12: argument type mismatch in function call (M::to_string(M::MY_ENUM_A))
error in <...>/function-invoke-mismatch-error.zeek, line 16 and error: type mismatch (M::MY_ENUM_B and error)
error in <...>/function-invoke-mismatch-error.zeek, line 16: argument type mismatch in function call (M::to_string(M::MY_ENUM_B))
error in <...>/function-invoke-mismatch-error.zeek, line 20 and error: type mismatch (M::e and error)
error in <...>/function-invoke-mismatch-error.zeek, line 20: argument type mismatch in function call (M::to_string(M::e))
Record coercion also reports noisy errors when coercing to a type that
has errors for individual fields, type clashing with "error":
$ zeek language/record-field-error.zeek
error in ./language/record-coerce-error.zeek, line 8: identifier not defined: MyEnumTypo
error in ./language/record-coerce-error.zeek, line 19 and ./language/record-coerce-error.zeek, line 5: type clash for field "e" ((coerce [$e=MY_ENUM_B, $s=test] to MyRecord) and MyEnum)
The script added as a test case reports the following messages *and*
dumps a core file. Printing the first error and a normal failure exit
seems sufficient. IMO triggering an abort() due to user scripting issues
is not something that Zeek should do
$ zeek ./identifier-not-defined-error.zeek
error in ./identifier-not-defined-error.zeek, line 10: identifier not defined: MyEnu
error in ./identifier-not-defined-error.zeek, line 10 and error: &default value has inconsistent type (M::MY_ENUM_A and error)
internal error in ./identifier-not-defined-error.zeek, line 11: type inconsistency in ZVal constructor
Aborted (core dumped)
Change is to skip certain checks when an error type is propagated.
Python, Ruby, Javascript, Go, ..., allow use of trailing commas and is even
recommended in some style-guides as it keeps diffs smaller. The black formatter
for Python even goes as far to take a trailing comma as an indication to
format a list one-item on a line.
It has been a bit unusual to not be able to put trailing commas in Zeek
scripts, so this change allows for it.
It explicitly prevents trailing commas in list expressions on the left
hand side. Concretely, this disallows trailing commas in the key list
expression during table initializations.
It probably allows for commas in more places that I haven't fully grasped.
Maybe we should tighten those down again if we find them surprising.
I've skipped treating overflows as warnings, as ++ wrapping around at 0
doesn't currently trigger a runtime error and might be expected to be
quiet and silently wrap.
Closes#2486
* origin/topic/vern/vec-construct-compat:
provide deprecated version of merge_type_list()
keep merge_types() externally available; address reviewing suggestion
change vector constructors to require direct type equivalence for non-arithmetics
Script and BIF functions with a single any parameter are excluded from
type checking regarding arguments. This makes it possible to call a
ScriptFunc with more arguments than it actually has parameters and frame
space for, causing heap-buffer-overflows.
This change runtime checks expected parameters and provided arguments
and short-circuits execution as well as logging runtime expression errors.
Fixes#2446
Seemed easiest to do it via the traversal infrastructure as we do not
otherwise track enough context/scope when instantiating break or next
statements.
Might be worth moving this out of src/parse.y, but didn't exactly know
where. Or maybe we wait until there's more such trivial validations
popping up
Fixes#2440
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;
