I finally found the bug in the code that I have bee commenting on. Specifically on
linux apache php 4.1.x (yes I will be upgrading) WHen I log in and mistype the user
id and pass word in addition to the squirrel mail error message I get a php error.
The orginal code in sqm_topdir in display_messages.php seemed to be the
problem. It appears that in this case if a file of some name doesn't exist and you
try
and check if it is a directory you have a problem. The following code change seems
to make the error go away. I can't see how it might break something.
function sqm_topdir(){
$topdir = '';
/**
* $levels is just to avoid a potential infinite loop in case
* things are REALLY broken. Shouldn't really ever happen.
*/
$levels = 0;
while (!(
file_exists($topdir . 'functions') &&
is_dir($topdir . 'functions') &&
file_exists($topdir. 'src') &&
is_dir($topdir. 'src')
)
&& $levels < 10){
$topdir .= '../';
$levels++;
}
return $topdir;
}
How does one bring this to the developer's attention?
