The namespace data is freed and set to NULL, but there remain references
to the namespace declaration nodes. This (rightfully) confuses libxml2
because its invariants are broken. We also have to remove all remaining
references from the subtree. This fixes the data corruption bug.
Closes GH-12681.
Now it's possible via removeAttribute("xmlns:prefix").
It was not possible to reuse a libxml2 function to reconcile because it
does not align with DOM behaviour.
Closes GH-12542.
The type will always be XML_ATTRIBUTE_NODE by construction via
php_dom_create_object, no need to check the type. Use an assertion
instead. This simplifies code and reasoning about error conditions.
There are two linked issues:
- Conflicts couldn't be resolved by changing the prefix name.
- Lacking a prefix would shift the namespace as the default namespace,
causing elements to suddenly become part of the namespace instead of
the attributes.
The output could still be improved by removing redundant namespace
declarations, but that's another issue. At least the output is
correct now.
Closes GH-11777.
* PHP-8.2:
Fix empty argument cases for DOMParentNode methods
Fix DOMCharacterData::replaceWith() with itself
Fix incorrect attribute existence check in DOMElement::setAttributeNodeNS()
Fix DOMEntity field getter bugs
These checks will always be false because we're dealing with elements
here. DOMElement always are of type XML_ELEMENT_NODE, so they don't need
to be checked.
* PHP-8.2:
Fix GH-11455: Segmentation fault with custom object date properties
Revert "Fix GH-11404: DOMDocument::savexml and friends ommit xmlns="" declaration for null namespace, creating incorrect xml representation of the DOM"
This reverts commit 7eb3e9cd17.
Although the fix follows the spec, it causes issues because a lot of old
code assumes the incorrect behaviour PHP had since a long time.
We cannot do this yet, especially not in a stable release.
We revert this for the time being.
See GH-11428.
* PHP-8.2:
Fix GH-11404: DOMDocument::savexml and friends ommit xmlns="" declaration for null namespace, creating incorrect xml representation of the DOM
The NULL namespace is only correct when there is no default namespace
override. When there is, we need to manually set it to the empty string
namespace.
Closes GH-11428.
* PHP-8.2:
Fix GH-11433: Unable to set CURLOPT_ACCEPT_ENCODING to NULL
Fix "invalid state error" with cloned namespace declarations
Fix lifetime issue with getAttributeNodeNS()
* Fix type confusion and parent reference
* Manually manage the lifetime of the parent
* Add regression tests
* Break out to a helper, and apply the use-after-free fix to xpath
Closes GH-11402.
* PHP-8.2:
Fix bug #77686: Removed elements are still returned by getElementById
Fix bug #81642: DOMChildNode::replaceWith() bug when replacing a node with itself
Fix bug #67440: append_node of a DOMDocumentFragment does not reconcile namespaces
