Bug description:Iterating over items + dba_delete not working
Description:
------------
With some handlers it's not possible to iterate over items if there will be
items deleted within iteration.
Test script:
---------------
// Script to delete items with specific prefix
$dba = dba_open(sys_get_temp_dir() . DIRECTORY_SEPARATOR .
uniqid('zfcache_dba_'), 'c', 'qdbm');
dba_insert('key1', 'value', $dba);
dba_insert('test2', 'value', $dba);
dba_insert('key3', 'value', $dba);
dba_insert('test4', 'value', $dba);
dba_insert('key5', 'value', $dba);
$key = dba_firstkey($dba);
var_dump($key);
while ($key !== false) {
$key = dba_nextkey($dba);
var_dump($key);
}
echo '#############################' . PHP_EOL;
$key = dba_firstkey($dba);
while ($key !== false) {
if (substr($key, 0, 3) === 'key') {
var_dump($key);
dba_delete($key, $dba);
}
$key = dba_nextkey($dba);
}
echo '#############################' . PHP_EOL;
$key = dba_firstkey($dba);
var_dump($key);
while ($key !== false) {
$key = dba_nextkey($dba);
var_dump($key);
}
Expected result:
----------------
string(4) "key1"
string(5) "test2"
string(4) "key3"
string(5) "test4"
string(4) "key5"
bool(false)
#############################
string(4) "key1"
string(4) "key3"
string(4) "key5"
#############################
string(5) "test2"
string(5) "test4"
bool(false)
Actual result:
--------------
flatfile -> correct
inifile -> wrong (breaks iteration after first delete)
gdbm -> wrong (breaks iteration after first delete)
qdbm -> correct
db4 -> correct
