Bug description: backward compatibility break in realpath()
Description:
------------
Hello,
regarding Bug #42778, I think should give a better explanation, why there
was a break in backward compatibility in the function realpath() on windows
between PHP 5.2.3 and 5.2.4, without any information in the manual or
changelog.
Additional, in the manual you can read:
| The resulting path will have no symbolic link,
| '/./' or '/../' components.
A "/./" as last component in a path, is the same as "/" as last component.
And thus the last "/" must be removed.
As you can see, the results with PHP 4.4.7(Win), PHP <=5.2.3(Win) and PHP
5.2.5(FreeBSD) are the same and like descriped in the manual.
Only with PHP >=5.2.3(Win) you have a different result.
The DirectoryIterator also have the same behaviour with all OS and
versions.
(BTW: With Perl or VBS I have also no trailing slash on Windows)
Regards,
Carsten
BTW: You should not forget:
For an PHP programer it's necessary, to have the same results in PHP
functions between PHP versions and operating systems. (especially without
informations)
Reproduce code:
---------------
Testscripts are executed with (in the given dirs):
$ .\php -n test.php
Testscript 1 in C:\php5
<?php
echo realpath('extras\\mibs\\');
?>
Testscript 2 in C:\php4
<?php
echo realpath('extras\\mibs\\');
?>
Testscript 3 in C:\php5
<?php
$dir = new DirectoryIterator('extras\\mibs\\');
echo $dir->getRealPath();
?>
Testscripts are executed with (in the given dirs):
$ ./php -n test.php
Testscript 4 in /usr/local/bin (with FreeBSD)
<?php
echo realpath('../include/');
?>
Testscript 5 in /usr/local/bin (with FreeBSD)
<?php
$dir = new DirectoryIterator('../include/');
echo $dir->getRealPath();
?>
Expected result:
----------------
on Windows with PHP5:
C:\php5\extras\mibs
on Windows with PHP4:
C:\php4\extras\mibs
on FreeBSD:
/usr/local/include
Actual result:
--------------
Testscript 1 with PHP 5.2.3:
C:\php5\extras\mibs
Testscript 2 with PHP 4.4.7 (Win):
C:\php4\extras\mibs
Testscript 1 with PHP 5.2.4 (Win):
C:\php5\extras\mibs\
Testscript 1 with PHP 5.2.5 (Win):
C:\php5\extras\mibs\
Testscript 3 with PHP 5.2.5 (Win):
C:\php5\extras\mibs
Testscript 4 with PHP 5.2.5 (FreeBSD):
/usr/local/include
Testscript 5 with PHP 5.2.5 (FreeBSD):
/usr/local/include
