Hi,
I've just tested with php 5.3.10, the bug is still here.
Do you still need me to test with version 5.3.9 ?
Here is the proof:
root@djavanubu:/root#
root@djavanubu:/root# cat b.php
#!/usr/local/bin/php
<?php
$Target="/mnt/M://BRASIL/Carlinhos Brown/Alfagamabetizado - Angel's Robot
List.mp3"; $Link="/mnt/M:/NEWBASE/BRASIL/Carlinhos Brown/Alfagamabetizado -
Angel's Robot List.1.2.mp3";
link($Target,$Link);
unlink($Target);
?>
root@djavanubu:/root#
root@djavanubu:/root# /usr/local/bin/php -v

Description:
------------
unlink() function truncates the file path name argument in some cases.
This bug appears also with the rename() function in the same cases.
The given source code use link() to duplicate a file, then unlink() to remove
the
source file. link() function works and unlink() bugs.
Test script:
---------------
#!/usr/local/bin/php
<?php
$Target="/mnt/M://BRASIL/Carlinhos Brown/Alfagamabetizado - Angel's Robot
List.mp3";
$Link="/mnt/M:/NEWBASE/BRASIL/Carlinhos Brown/Alfagamabetizado - Angel's Robot
List.1.2.mp3";
link($Target,$Link);
unlink($Target);
?>
Expected result:
----------------
unlink() should remove the "/mnt/M://BRASIL/Carlinhos Brown/Alfagamabetizado -
Angel's Robot List.mp3" file
Actual result:
--------------
root@djavanubu:/# ./b.php
Warning: unlink(BRASIL/Carlinhos Brown/Alfagamabetizado - Angel's Robot
List.mp3): No such file or directory in /b.php on line 8
