Show the script below the text.

When I create a new db file, extras data has been stored. 
In all cases, it was the script itself (ask me if you need 
the new db file directly).
I think it's a bug (or a new backup feature ;).

Config details :
gdbm 1.8.0
libc6
kernel 2.4.10
data on a reiserfs partition

Is it due to a default filesize ?
If yes do you make a zero fill of the extra memory used ?

<?
$id = dba_open("/tmp/test2.db","n","gdbm");
if(!$id){
	echo "Erreur dba_open";
	exit;
}
dba_replace("key","This a test!",$id);
if(dba_exists("key",$id)){
	echo dba_fetch("key",$id);
}else{
	echo "Not found";
}
dba_close($id);
?>

I have seen the same thing.  It only seems to happen to me when I am including other php files.  If I take out all require()'s, the db is zero'ed out again.

Any suggestions?

For anyone else with this problem:

Apparently calling the optimize function immediately after the create will set everything back to nulls so the script itself is removed:

$dbRC = dba_optimize($dbID);

I would still like to know how the default size is determined of the database file.  I guess I will look for that info on GNU sites though.

think you can try a recent non-stable snapshot?
