Bug #73379 [Asn->Nab]: BC break from 7.0.10 to 7.0.11+

Edit report at https://bugs.php.net/bug.php?id=73379&edit=1 ID: 73379 Updated by: ab@php.net Reported by: goetas at gmail dot com Summary: BC break from 7.0.10 to 7.0.11+ -Status: Assigned +Status: Not a bug Type: Bug Package: SimpleXML related Operating System: linux PHP Version: 7.0.12 Assigned To: nikic Block user comment: N Private report: N New Comment: I would like to keep this patch further on. It is clearly a BC breach, as erroneous data won't be handled anymore. But reverting it back and forth seems not feasible, besides it's related to a bug fix. I know, @goetas, that it's not quite fair in regard to your project. However, the patch is already released, there seems to be no major BC breach, and you've released a new version to workaround this. Thanks.

I guess you are not planning to revert the bugfix, right? ------------------------------------------------------------------------ [2016-10-25 19:23:52] nikic@php.net IIRC this issue came up when implementing proper null-coalesce support for SimpleXMLElement. $sxe->foo ?? 'bar' is supposed to be the same as isset($sxe->foo) ? $sxe->foo : 'bar'. If isset($sxe->foo) and $sxe->foo behave differently, because the latter takes namespaces into account while the former doesn't, that obviously leads to problems. Anyway, I don't have a strong opinion here. ------------------------------------------------------------------------ [2016-10-25 14:56:16] cmb@php.net In my opinion, bug #72971 is a valid bug report and as such fixing the issue is appropriate even in a revision. Nikita, what do you think? ------------------------------------------------------------------------ [2016-10-23 10:53:43] goetas at gmail dot com Description: ------------ There is a different behavior on the php simple xml parser. There is the test code https://3v4l.org/Jve27 As you can see there is a new behavior starting from 7.0.11 This looks to be introduced with https://bugs.php.net/bug.php?id=72971 that does exactly the opposite. Feel free to close it as Not a bug, but BC breaks in bugfix release broke https://github.com/schmittjoh/serializer ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=73379&edit=1
