Bug Type: ODBC related
Operating System: Windows XP
PHP Version: 5.2.12
New Comment:
We identify the problem is within php_curl.dll. We are using PHP
v5.2.12, and find that all newer PHP versions have this problem. We have
to backtrack to the older PHP v5.2.0 before this problem disappears.
The problem source code:
PHP v5.2.12 ext\curl\interface.c Line 670
#ifdef PHP_CURL_NEED_OPENSSL_TSL
if (!CRYPTO_get_id_callback()) {
int i, c = CRYPTO_num_locks();
php_curl_openssl_tsl = malloc(c * sizeof(MUTEX_T));
PHP v5.2.0 ext\curl\interface.c Line 609
#ifdef PHP_CURL_NEED_OPENSSL_TSL
{
int i, c = CRYPTO_num_locks();
php_curl_openssl_tsl = malloc(c * sizeof(MUTEX_T));
The only difference is the if statement:
if (!CRYPTO_get_id_callback())

Description:
------------
We have a resource leak problem when using Apache 2.2.11 and PHP 5.2.12
with odbc_connect() and odbc_close() functions on dbase or Microsoft
Access.
>From my observe, it will leak some (Nonpaged) kernel Memory and some
handles not free by the Apache(HTTPD.EXE).
And I also tested no this resource leak problem on Apache 2.2.11 and
PHP 5.2.0.
Thanks.
Chris

Access;DriverId=25;DefaultDir=D:\;DBQ=D:\db1.mdb;";
$dsnDBF = "DRIVER=Microsoft dBase Driver
(*.dbf);UID=admin;UserCommitSync=Yes;Threads=3;Statistics=0;SafeTransactions=0;PageTimeout=5;MaxScanRows=8;MaxBufferSize=2048;FIL=dBase
IV;DriverId=277;Deleted=1;DefaultDir=D:\;DBQ=D:\datasource\;CollatingSequence=ASCII;";
