Hi,
I've got a bug with is_link and lstats. Any symlinks not created in the
current session, will not be read. This only occurs in the Apache 2 SAPI
version, not in the CLI version.
Script:
/<?
$symlink = '/tmp/link-test';
if (file_exists($symlink)) unlink($symlink);
symlink('/tmp/pear', $symlink);
echo (file_exists($symlink) ? is_link($symlink) ? "Correct" :
"ERROR" : "Couldn't create the link"), "<br/>\n";
$symlink = '/tmp/link-persist';
if (!file_exists($symlink)) symlink('/tmp/pear', $symlink);
echo (file_exists($symlink) ? is_link($symlink) ? "Correct" :
"ERROR" : "Couldn't create the link"), "<br/>\n";
?>/
First run:
/ Correct
Correct

Second run:
/ Correct

Next runs:

/I've recently start using the daily snapshots op PHP, but I also tried
it on version 5.2.1, which shows the same result. It used to work just
fine, so I'm sure this isn't the expected result. I've recently upgraded
from Ubuntu Edgy (6.10) to Feisty (7.04), with kernel and apache update,
so I believe that the problem is related to that.
I've straced the process (see attachment), but I can't pinpoint the
problem. This is a big issue for me, can anyone point me in the right
direction to find the source of this problem.
Thanks,
Arnold
