Reduce false positives for @hsh{$s} and @ary[$s] warnings

This resolves tickets #28380 and #114024.

Commit 95a31aad5 did something similar to this for the new %hash{...}
syntax.  This commit extends it to @ slices and combines the two
code paths.

The heuristics in toke.c can easily produce false positives.  So the
op is flagged as being a candidate for the warning.  Then when op.c
has the op tree available, it examines it to see whether the heuristic
may have been a false positive.

This avoids bugs with qw "foo bar baz" and sub calls triggering
the warning.

The source code is no longer available for the warning, so we recon-
struct it from the op tree, skipping the subscript if it is anything
other than a const op.

This means that @hash{$foo} comes out as @hash{...} and @hash{foo} as
@hash{"foo"}.  It also meeans that @hash{"]"} is displayed correctly
instead of as @hash{"].

Commit 95a31aad5 also modified the heuristic for %hash{...} to exempt
qw altogether.  But it did not exempt it if it was preceded by a tab.
So this commit rectifies that.

This commit also improves the false positive detection by exempting
any ops returning lists that can get past toke.c’s heuristic.  I went
through the entire list of ops, but I may have missed some.

Also, @ slices on the lhs of = are exempt, as they change the context
and are hence actually useful.

op.c:leave_scope: use mg_free before sv_force_normal

This is part of ticket #119295.

Commit 7fa949d (5.19.3) allowed copy-on-write with compile-time con-
stants.  That caused this to fail:

use Variable::OnDestruct:
{
 my $h = "foo";
 on_destruct $h, sub { warn defined $_[0] ? $_[0] : "undef" };
 $x++; # prev statement must not be last in the block
}

It prints undef instead of foo.

It turns out this is much older:

use Variable::OnDestruct;
{
 my $h = __PACKAGE__;
 on_destruct $h, sub { warn defined $_[0] ? $_[0] : "undef" };
 $x++; # prev statement must not be last in the block
}

This one prints undef starting with 5.17.3 (a6d7a4ac1).

But even before that, this prints undef:

use Variable::OnDestruct;
{
 my $h = \1;
 on_destruct $h, sub { warn defined $_[0] ? $_[0] : "undef" };
 $x++; # prev statement must not be last in the block
}

In all these cases, the scalar is getting undefined before free magic
triggers (Variable::OnDestruct uses free magic).

Usually when a scalar is freed, the magic is triggered before anything
else.  When a lexical scalar is ‘freed’ on scope exit (cleared for
reuse on scope entry), the order is different.  References, globs and
copy-on-write scalars become undefined (via sv_force_normal) before
magic is triggered.

There is no reason for the order to be different here, and it causes
unpredictable behaviour (you never know when you will or will not have
a cow).  So change the order in scope exit to match regular freeing.

10 years agoFewer false positives for %hash{$scalar} warning
Father Chrysostomos [Thu, 12 Sep 2013 21:30:41 +0000 (14:30 -0700)]
Fewer false positives for %hash{$scalar} warning

Instead of warning in the lexer, flag the op and then warn in op.c,
when the op tree is available, so we don’t end up warning for actual
lists or for sub calls.

Also, only warn in scalar context, as in list context $hash{$scalar}
and %hash{$scalar} do different things.

In op.c we no longer have easy access to the source code, so recon-
struct the hash/array access based on the op tree.  This means
%hash{foo} becomes %hash{"foo"}.  We only reconstruct constant keys,
so %hash{++$x} becomes %hash{...}.  This also corrects erroneous
dumps, like %hash{"} for %hash{"}"}.

Instead of triggering the warning solely based on the op tree, we
still keep the heuristic in toke.c, so that common workarounds for
that warning (e.g., {q<key>} and {("key")}) continue to work.

The heuristic in toke.c is tweaked to avoid warning for qw().

In a future commit I plan to extend this to the existing @array[0] and
@hash{key} warnings, to avoid false positives.

Hard-code op name in ck_exists|delete errors

The reason is manifold:
• ck_exists and ck_delete are each only ever called with one op type,
  so we can hard-code the op, which takes less code.
• The messages in perldiag are more helpful if they include
  the op name.
• Changing them in op.c too avoids the need for
  diag_listed_as clutter.

ting to that.)
