Bug #37531 Persistent connection corruption
Submitted: 2006-05-19 22:29 UTC Modified: 2006-08-22 19:45 UTC
From: jreed at myers dot com Assigned: tony2001
Status: Closed Package: OCI8 related
PHP Version: 5.1.4 OS: Linux - 386
Private report: No CVE-ID:
 [2006-05-19 22:29 UTC] jreed at myers dot com
Description:
------------
If you open a persistent connection on one page, then on another page you open a file using fopen, thus creating a file resource, and then attempt to obtain a persistent oci8 connection using ociplogon(), the returned resource is not a valid oci8 connection resource.  If you then attempt to use that connection resource you get the following warning:

"supplied resource is not a valid oci8 connection resource"

If you close the file using fclose() prior to calling ociplogon() then everything works fine.

This problem was introduced in v5.1.3 and continues in 5.1.4.


Reproduce code:
---------------
page1.html
<?php
putenv("TNS_ADMIN=/etc/myers");
$conn_ora = ociplogon("portal", "portal123", "eng2");
ocilogoff($conn_ora);

header("Location: page2.html");
?>

page2.html
<?php
$fp = fopen('/tmp/test.log','a');

$conn_ora = ociplogon($username, $password, $db);

$sql = "select * from dual";
$stmt = ociparse($conn_ora, $sql);
?>


Expected result:
----------------
Page redirects to second page and get a blank page.

Actual result:
--------------
Warning: ociparse(): supplied resource is not a valid oci8 connection resource in /www/myers/sites/portal/main/orders/test2.html on line 7

Warning: ocilogoff(): supplied resource is not a valid oci8 connection resource in /www/myers/sites/portal/main/orders/test2.html on line 8

This fix did not make it into the latest 5.1.5 release.  I do not see any CVS snaps for the 5.1.x series, only for Beta 5.2.x.  Does this mean this fix will not be released until v5.2?

Yes, 5_1 branch is only for security fixes.
