New Comment:
- The cascon database is not a CDB database.
- The failure is in malloc (safe_emalloc)
which tries to allocate more memory then available.
This cannot be fixed within dba.
- The workaround to check the file length would slowdown
CDB by adding 2 additional seeks. This contradicts its
design.
- Hence there is nothing to fixed -> closed

OTOH, I don't think that Nokia/Cascon are using the CDB but something
of their own invention.

It actually returns empty string. When you change the
check to while ($key !== false) it'll crash:

Unfortunatly, I cannot provide you the DB which I'm refering to,
because - as already mentioned - it is the contacts-database from a
nokia 9210i which contains sensitive data. I tried to get a sample
contacts.cdb directly from nokia, but they haven't been supportive :-(
But I found the following two cdb-databases on the internet:
http://web.mit.edu/cascon/updates/cascon.cdb (does not work with the
provided code)
http://cvs.sourceforge.net/viewcvs.py/*checkout*/cdbfile/cdbFile/cdbFile/Attic/test.cdb?rev=1.1.1.1
(works fine with my code)
HTH

Description:
------------
I'm trying to open the contacts-databse from a nokia 9210i mobile, but
it doesn't work.
Reproduce code:
---------------
$db_conn = dba_open("contacts.cdb","r","cdb");
if (!$db_conn) die ("opening failed");
$key = dba_firstkey ($db_conn);
while ($key != false)
{
echo $key."<br />";
echo dba_fetch ($key, $db_conn)."<br /><br />";
$key = dba_nextkey ($db_conn);
}
dba_close($db_conn);
Expected result:
----------------
...to get a list of key-value pairs.
Actual result:
--------------
The code didn't produce the expected output nor any error message. It
seems that the commands dba_firstkey and dba_nextkey always return
false instead of a key.
