PHP Bug Type: ODBC related
Bug description: odbc connection closed twice
The code in php_odbc.c, that checks if a persistent connections still
alive, when finds a bad connection will try to deallocate the connection
twice causing Access Violation in SQLServer ODBC driver
zend_hash_del will make a call to _close_odbc_connection
through destruction process.
safe_odbc_disconnect(db_conn->hdbc);
SQLFreeConnect(db_conn->hdbc);
Aren't nessessary here and will cause Access Violation in SQLServer
driver.
Line 2125 in php_odbc.c
if(ODBCG(check_persistent)){
RETCODE ret;
UCHAR d_name[32];
SWORD len;
ret = SQLGetInfo(db_conn->hdbc, SQL_DATA_SOURCE_READ_ONLY, d_name,
sizeof(d_name), &len);
if(ret != SQL_SUCCESS || len == 0) {
zend_hash_del(&EG(persistent_list), hashed_details, hashed_len + 1);
safe_odbc_disconnect(db_conn->hdbc);
SQLFreeConnect(db_conn->hdbc);
goto try_and_get_another_connection;
}
}
