| Subject: | Serializing an object that acts like a scalar fails |
The error appears as something like this:
Not a HASH reference at /usr/share/perl5/PHP/Serialization.pm line 454.
The issue was in the $type eq 'obj' condition, at scalar(keys %{$val}).
In my case, $val was indeed an object, of class
JSON::backportPP::Boolean, but I think it was not something that could
be treated as a hashref. It appeared that its value in a scalar context
was simply the string "true".
I hacked around it at line 453 in a way that is not worth submitting as
a patch:
if($class eq 'JSON::backportPP::Boolean') {
$buffer .= sprintf('i:%d;', $val eq 'true' ? 1 : 0);
}
A sort of minimal test case, as dumped by Data::Dumper and hand-
sanitized of sensitive data is this object:
$x = {
foo => 1234,
bar => {
baz => bless( do{\(my $o = 1)}, 'JSON::backportPP::Boolean' ),
quux => $VAR1->[0]{permissions}{baz},
}
};
So I would expect $x->{bar}{baz} == $x->{bar}{quux} == 1, which is what
my hack accomplishes for this one case.
I could possibly provide more information about that JSON class if it
would help, but I don't happen to know anything about it off the top of
my head.
