Add DOMNode::compareDocumentPosition() (#12146) Reference: https://dom.spec.whatwg.org/#dom-node-comparedocumentposition
2023-09-09 07:14:26 +08:00
- DOM:
. New methods and constants were added to some DOM classes. If you inherit
from these and you happen to have a method or property with the same name,
you might encounter errors if the declaration is incompatible.
Consult sections 2. New Features and 6. New Functions for a list of
newly implemented methods and constants.
UPGRADING: Move the validation of the rounding mode to Backward Incompatible Changes
2023-09-22 23:35:03 +08:00
- Standard:
. round() now validates the value of the $mode parameter and throws a ValueError
for invalid modes. Previously invalid modes would have been interpreted as
PHP_ROUND_HALF_UP.

Reimplement `php_round_helper()` using `modf()` (#12220) This change makes the implementation much easier to understand, by explicitly handling the various cases. It fixes rounding for `0.49999999999999994`, because no loss of precision happens by adding / subtracing `0.5` before turning the result into an integral float. Instead the fractional parts are explicitly compared. see GH-12143 (this fixes one of the reported cases) Closes GH-12159 which was an alternative attempt to fix the rounding issue for `0.49999999999999994`
2023-09-20 00:05:05 +08:00
- Standard:
. The internal implementation for rounding to integers has been rewritten
to be easier to verify for correctness and to be easier to maintain.
Some rounding bugs have been fixed as a result of the rewrite. For
example previously rounding 0.49999999999999994 to the nearest integer
would have resulted in 1.0 instead of the correct result 0.0. Additional
inputs might also be affected and result in different outputs compared to
earlier PHP versions.

fix file() flags error-check the old flag check was flawed and would miss some flags, for example: file(__FILE__, FILE_APPEND); is invalid, but the old flags error check would miss it: https://3v4l.org/b2W9u Closes GH-11483
2023-06-20 00:46:05 +08:00
Implement #53655: Improve speed of DOMNode::C14N() on large XML documents The XPath query is in accordance to spec [1]. However, we can do it in a simpler way. We can use a custom callback function instead of a linear search in XPath to check if a node is visible. Note that comment nodes are handled internally by libxml2 already, so we do not need to differentiate between node types. The callback will do an upwards traversal of the tree until the root of the canonicalization is reached. In practice this will speed up the application a lot. [1] https://www.w3.org/TR/2001/REC-xml-c14n-20010315 section 2.1 Closes GH-12278.
2023-09-23 00:46:18 +08:00
* The performance of DOMNode::C14N() is greatly improved for the case without
an xpath query. This can give a time improvement of easily two order of
magnitude for documents with tens of thousands of nodes.
