I also tried adding ini_set("max_execution_time", "180") to the script
and it changed nothing. Just to make sure it was not hitting this limit
too.

I do not have this enabled. My configure line looks like so:
./configure --enable-ftp --with-ldap=/usr/local/openldap
--with-mysql=/usr --with-openssl=/usr/local/openssl
I thought for the memory_limit directive to take effect would mean I
would to have had to add --enable-momory-limit to the configuration.
Has this changed recently (i.e. >= 4.2.1)?

Does your PHP have a memory limit?

BTW, The files I am examining are all text.

Here is my src:
--------------------
$files = array();
$dirs = array();
function getMD5OfFile($f) {
return md5_file($f);
//return exec("md5sum ".$f." | awk '{print $1}'");
}
function getFiles($d) {
global $files, $dirs;
clearstatcache();
if($dir = @opendir($d)) {
while(($file = @readdir($dir)) !== false) {
if(($file != ".") && ($file != "..")) {
if(is_dir($d."/".$file)) $dirs[] = $d."/".$file;
elseif(is_file($d."/".$file) && (substr($file,0,1) != "."))
$files[] = $d."/".$file;
}
}
}
}
/** Get files for directories **/
getFiles("/home/webdev");
while(($dir = array_shift($dirs)) !== null) {
getFiles($dir);
}
/** Ouptut findings **/
while(($file = array_shift($files)) !== null) {
echo $file.": ". getMD5FromFile($file) ."\n";
}
------------------
I first tried this with v4.2.1. What I am trying to do is get the MD5
for every file within the filesystem. Unfortunately this code freezes
after about 20 or so files (md5_file() or exec() returns ok until
then). If I uncomment the exec() return and comment the md5_file()
return, the script hangs at exactly the same spot. If comment both out
and run the script without md5'ing any files, I get a listing of all
files (no problem).
I have also tried replacing the md5_file() code with one that was
listed here http://www.php.net/manual/en/function.md5-file.php that
will read the file into a variable and do a md5() on that var.
Unfortunately I got a FATAL: emalloc() error using that method.
Finally, I tried getting the upgrading to v4.3.0-dev (latest snapshot
from snaps) and got the same results.
I cannot figure out why this hangs and does not bomb out. I think it
has something to do with maybe a cache of some sort or the memory
buffers are filling up. Maybe even something to with how I am
traversing the array of directories? But then, why would it work
without the md5 cals? I do not know, but I thought I would post it here
and see what you guys think. TIA.
