#44125 [NEW]: Doubled memory usage on XInclude with Unix-style filenames
From: ezyang@php.net
Operating system: Windows Vista
PHP version: 5.2.5
PHP Bug Type: XML related
Bug description: Doubled memory usage on XInclude with Unix-style filenames
Description:
------------
On Windows, XML files with large amounts of XIncludes (such as the PHP
Documentation Manual, where this bug was discovered) exhibit curious
behavior when they were loaded with Unix-style paths: they appear to
require double the memory than if they were loaded with Windows-style
paths.
Reproduce code:
---------------
<?php
// note forward slashes
$file = 'C:/Users/Edward/phpdoc/manual.xml';
$dom = new DOMDocument();
echo "Loading XML\n";
$dom->load($file);
echo "Performing XIncludes\n";
$dom->xinclude();
Expected result:
----------------
With an external process manager (Task Manager or Process Explorer),
memory usage should spike on $dom->load(), and then stay constant during
XIncludes. XIncludes should be very quick.
Actual result:
--------------
XIncludes take a long time to run, and double the memory usage of
php.exe.
A curious side-effect of this is that call to $dom->load() immediately
after the offending XInclude is extremely slow. This can be from a
completely separate process.
