structure under threading.  This solves it by changing the

Ton Hospel [Fri, 20 May 2011 00:05:16 +0000 (17:05 -0700)]
[perl #85026] Deleting the current iterator in void context

Looking at the delete code I see another strange thing. If the delete
of the current iterator is done with the G_DISCARD flag, the corres-
ponding value is not freed and survives until the lazy deleted entry
gets removed on the next hash iteration. This is easily demonstrated
like this:

perl -wle '
sub DESTROY { print "DESTROY" }
%a=(a=>bless[]);
each %a;
delete $a{a};
print "END"
'

This prints:

END
DESTROY

notice the difference with:

perl -wle '
sub DESTROY { print "DESTROY" }
%hash = (a => bless[]);
each %hash;
$dummy = delete $hash{a}; $dummy = 0;
print "END"
'

This prints:

DESTROY
END

This is easily solved by always replacing the deleted entry value with
&PL_sv_placeholder. It actually simplifies the code a bit except for the
fact that the mro_method_changed from free_hash_ent now has to be done

13 years ago[perl #85026] deleting elements in a HASH iterator
Ton Hospel [Mon, 16 May 2011 15:33:07 +0000 (08:33 -0700)]
[perl #85026] deleting elements in a HASH iterator

Internally a perl HASH is an array of single linked chains of entries.
Deleting an element means removing the correct chain entry by replacing
the pointer to the removed entry with a pointer to the next entry and
then freeing the deleted entry

However, if the deleted element is the current entry the deleted entry
is kept after removing it from the chain and the LAZYDEL flag is set.
Only on the next iteration is the element actually removed and the
iterator is set to the next entry.

However, if you delete the current iterator and then delete the next
element in the same chain the "next" pointer of the iterator is not
updated because the iterator is not on the chain anymore. That means
that when the next iteration looks up the iterator next pointer it
will point to the freed memory of the second element.

This patch fixes the places where the delete is done. Drawback is that
you may never forget to do the lazydel fixup in at any place where the
entry chain gets shortened.
