Summary: Segfault occurs in simple flatfile test
Status: Open
Type: Bug
Package: DBM/DBA related
Operating System: Linux
PHP Version: 5.4.0
Block user comment: N
Private report: N
New Comment:
The first echo in the test case is incorrect. It should read:
echo "open ./test0.dbm as a flatfile db, and insert a key\n"

Description:
------------
I have a simple test case that dba_opens a flatfile once which returns a
resource descriptor, inserts a key and value into that flatfile, opens the same
flatfile again returning a second resource, closes the second resource, and
again reads the a key from the first descriptor. This causes a seg fault.
Test script:
---------------
Note, this test case requires the dba extension to be installed.
<?php
$handler = "flatfile";
$db_filename = $db_file = dirname(__FILE__) .'/test0.dbm';
@unlink($db_filename);
@unlink($db_filename.'.lck');
echo "open ./test.inc as a flatfile db, and insert a key\n";
$db_file1 = dba_popen($db_filename, 'n', $handler);
dba_insert("key1", "This is a test insert 1", $db_file1);
echo "open a second resource on the same file\n";
$db_file2 = dba_popen($db_filename, 'n', $handler);
echo "close the second resource\n";
dba_close($db_file2);
echo "query the key value again from the first resource, after closing second
resource\n";
echo dba_fetch("key1", $db_file1), "\n";
?>
Expected result:
----------------
I expect that instead of seg faulting on the final line, that it would instead
print:
This is a test insert 1
Actual result:
--------------
