[PHP-DEV] Bug #10499: User abort causes page to be dumped into error_log

[dbenson]

From: [EMAIL PROTECTED]
Operating system: Linux / Solaris
PHP version:  4.0.4pl1
PHP Bug Type: Output Control
Bug description:  User abort causes page to be dumped into error_log

With output buffering enabled, if the user presses the stop button in their web client 
on a page which is executing slowly, when the code completes the page results are 
written to the apache error_log.

Run the included script and hit the stop button before it completes. The page output 
(numbers) will be written to the error_log.



Happens on both Linux (RH7) and Solaris (2.7)

[PHP-DEV] PHP 4.0 Bug #9197 Updated: crash in _efree

[dbenson]

ID: 9197
User Update by: [EMAIL PROTECTED]
Status: Open
Bug Type: OCI8 related
Description: crash in _efree

Included is a short script that reproduces the problem

The first part contains a workaround, that I have implemented in my code. From the 
docs I was under the impresison I had to manipulate the clob through the clob calls, 
but OCIFetchStatement appears to handle the data correctly.

The oracle schema is:
SQL> desc extra_info  
 Name  Null?Type
 -  
 ITEM_ID   NOT NULL VARCHAR2(32)
 XMLCLOB
 CREATE_DATE   NOT NULL DATE
 UPDATE_DATE   NOT NULL DATE
 CLOB_UPDATE_DATE  NOT NULL DATE


<%
$Conn = OCINLogon ('vignette', 'vignette', 'wom_dev');

// working version
$Stmt = OCIParse ($Conn, "
select xml
  from extra_info
 where item_id = '6E1DB91CF0654384E034080020B33146'");
$Clob = OCINewDescriptor ($Conn, OCI_D_LOB);
OCIExecute ($Stmt);
$nrows = OCIFetchStatement ($Stmt, $rs);

// non-working version
$Stmt = OCIParse ($Conn, "
select xml
  from extra_info
 where item_id = '6E1DB91CF0654384E034080020B33146'");
$Clob = OCINewDescriptor ($Conn, OCI_D_LOB);
OCIExecute ($Stmt);
while (OCIFetch ($Stmt)) {
$Clob = OCIResult ($Stmt, 'XML');
}
$ExtraXML = @$Clob->load();
%>
