Bug description:realpath not resolving symlinks corrrectly
Description:
------------
When creating a symlink in Windows to an absolute path with a lower case
drive letter, PHP will not resolve the canonicalized absolute pathname
(realpath) correctly.
This is obvious when you have nested symlinks.
When you run realpath of a nested symlink it returns the next symlink it
links to, rather than the top absolute pathname.
On Linux it works correctly.
One work around that can be used is:
$link = 'f:\link3';
do {
$link = realpath($link);
} while (realpath($link) !== false && $link !== realpath($link));
Test script:
---------------
Windows test:
F:\>mkdir target
F:\>mklink /D link1 f:\target
F:\>mklink /D link2 f:\link1
F:\>mklink /D link3 f:\link2
F:\>php -r "var_dump(realpath('link3'));"
Linux test:
$ mkdir target
$ ln -s target link1
$ ln -s link1 link2
$ ln -s link2 link3
$ php -r "var_dump(realpath('link3'));"
Expected result:
----------------
Windows test:
string(9) "F:\target"
Linux test:
string(12) "/root/target"
Actual result:
--------------
Windows test:
string(9) "f:\\link2"
Linux test:
string(12) "/root/target"
