Bug #72738 [NEW]: realpath() expands junction points
From: anrdaemon at freemail dot ru
Operating system: Windows
PHP version: 7.1.0beta1
Package: Filesystem function related
Bug Type: Bug
Bug description:realpath() expands junction points
Description:
------------
On Windows, realpath() expands the directory junction points.
According to an apparently authoritative assesment of pajoye@php.net in
the https://bugs.php.net/bug.php?id=72642 , this
shouldn't happen.
Test script:
---------------
<?php
$rootdir = substr(getenv('SystemRoot'), 0, 3);
$tmpdir = getenv('TEMP');
shell_exec("mklink /J \"{$rootdir}home\" \"{$rootdir}Users\"");
shell_exec("mklink /J \"{$tmpdir}\\test.dir\"
\"{$rootdir}home\\Public\\Desktop\"");
$file = "{$tmpdir}\\test.dir\\desktop.ini";
$rfile1 = realpath($file);
$rfile2 = realpath($rfile1);
printf("orig.file name: %s\n", $file);
printf("realpath(name): %s (%s)\n", $rfile1, $file == $rfile1 ? 'Ok' :
'fail');
printf("THE real name: %s (%s)\n", $rfile2, $file == $rfile2 ? 'Ok' :
'fail');
rmdir("{$rootdir}home");
rmdir("{$tmpdir}\\test.dir");
Expected result:
----------------
According to pajoye@php.net, expansion shouldn't happen, and all paths
must be the same == the original path.
Actual result:
--------------
All paths are different. On each iteration, realpath() only expands a
portion of nested junctions.
