Thank you for checking on this.
I am using debain stable with a 2.6.14.3 kernel. The filesystem in
question is ext2 on a 48 MB ramdisk.
I also did the following on another machine using ext2 on a harddisk
with command line php.
<?php
/*
-rw-r--r-- 1 user user 0 Dec 21 12:41 A
-rw-r--r-- 1 user user 0 Dec 21 12:41 B
lrwxr-xr-x 1 user user 1 Dec 21 12:43 C -> A
-rw-r--r-- 1 user user 91 Dec 21 12:41 test.php
*/
$FILE = 'C';
while(file_exists($FILE)){
echo "$FILE exists\n";
echo `ls -l C`;
if(!unlink($FILE)){
echo "Unable to delete $FILE\n";
echo `ls -l C`;
}else{
echo "Deleted $FILE\n";
}
echo "====\n";
}
/*
Output:
>php5 ./test.php
C exists
lrwxr-xr-x 1 user user 1 Dec 21 12:59 C -> A
Deleted C
====
C exists
ls: C: No such file or directory
Warning: unlink(C): No such file or directory in
/home/user/x/test.php on line 14
Unable to delete C
ls: C: No such file or directory
====
C exists
ls: C: No such file or directory
Warning: unlink(C): No such file or directory in
/home/user/x/test.php on line 14
Unable to delete C
ls: C: No such file or directory
====
*/
?>
This shows that apache is not responsible for the problem.
Note also that if I delete A and C within the loop the code works as
expected and the loop only executes once. So file_exists() is seeing
"A" when I tell it to delete "C" and unlink is seeing "C" as it
should.
Any ideas where to start to look for the cause of the problem?
