Description:
------------
i used integer numbers packed into binary strings as keys.
for some numbers dba's cdbmake handler produces files that can't be
read by Bernshtein's tools like cdbtest and CPAN's perl module
CDB_File. And vice versa files produced by Bernshtein's cdbmake and
CPAN's perl module CDB_File can't be read by dba's cdb handler.
Reproduce code:
---------------
<?php
$handler = 'cdb_make';
$db_file = '129php.cdb';
echo "database handler: $handler\n";
// print md5 checksum of 129test.cdb which is generated by
cdb_make program
var_dump(md5_file(dirname(__FILE__).'/129test.cdb'));
if (($db_make=dba_open($db_file, "n", $handler))!==FALSE) {
dba_insert(pack('i',129), "Booo!", $db_make);
dba_close($db_make);
// write md5 checksum of generated database file
var_dump(md5_file($db_file));
} else {
echo "Error creating database\n";
}
?>
Expected result:
----------------
database handler: cdb_make
string(32) "1f34b74bde3744265acfc21e0f30af95"
string(32) "1f34b74bde3744265acfc21e0f30af95"
Actual result:
--------------
database handler: cdb_make
string(32) "1f34b74bde3744265acfc21e0f30af95"
string(32) "b9ee8bfe966a01e287f8aa45b3fcc958"
