Subject: [XML-SIG] Include files for processing
Message-ID: <20060702185242.GA78114@mail1.thewrittenword.com>

We're curring doing SAX parsing with PyXML for a few applications but
need to add DTD validation and in-place file inclusion (I think
XInclude allows you to include XML files from within another XML
document). I don't think we can continue using PyXML as it doesn't
support XInclude:
  http://mail.python.org/pipermail/xml-sig/2004-May/010260.html

What else should we look at? 4Suite? lxml?

Is the conversion from code using the PyXML SAX parser relatively
simple to 4Suite/lxml?

Summary: bug in xmlparse_GetInputContext

Initial Comment:
SHORT VERSION:
I think the call in extensions/pyexpat:1089 

result = PyString_FromStringAndSize(buffer + offset, size) 

should be:

result = PyString_FromStringAndSize(buffer + offset,
size - offset)


This this change, my application does not core dump any
more.




LONG VERSION:
I have a Apache + mod_python + Expat(2.0.0) application.  

Under Linux (Gentoo), everything works as expected.

Under Mac OS X, everything works as expected until I
increase the size of a particular XML template file. 
The entire application will segfault.  It does not
matter what I add to this file.  It can be whitespace,
comments, or additional XML markup.

I've included some of the output I gathered from gdb. 
Here is what I am sure of:

I put a breakpoint on extensions/pyexpat.c:1089.  The
31st call from this function to
PyString_FromStringAndSize(buffer + offset, size) will
cause the segfault coredump.

I then followed this 31st call to
PyString_FromStringAndSize.  As I stepped through the
execution, the call to memcpy(op->ob_sval, str, size)
in Objects/stringobject.c:80 is the culprit.

Just before this call, I printed out the values of the
arguments:

(gdb) print *op
$14 = {
  ob_refcnt = 1, 
  ob_type = 0x508f88, 
  ob_size = 11070, 
  ob_shash = -1, 
  ob_sstate = 0, 
  ob_sval = "<"
}
(gdb) 


(gdb) print op->ob_sval + 0
$23 = 0x1aa8e14 "<li><a tal:href=\"string:
/public/justforstudents.xhtml\">Just for
Students</a></li>\n\t<li>&nbsp;</li>\n\t<li><a
tal:href=\"string:
/public/departments.xhtml\">Departments</a></li>\n\t<li><a
tal:href=\"string: "...
(gdb) 


(gdb) print str
$15 = 0x16b44c3 "<a tal:href=\"string:
/public/justforstudents.xhtml\">Just for
Students</a></li>\n\t<li>&nbsp;</li>\n\t<li><a
tal:href=\"string:
/public/departments.xhtml\">Departments</a></li>\n\t<li><a
tal:href=\"string: /pub"...
(gdb) 


(gdb) print size
$16 = 11070
(gdb)


When I allow the execution to continue to the memcpy, I
get the following exception:

(gdb) s

Program received signal EXC_BAD_ACCESS, Could not
access memory.
Reason: KERN_INVALID_ADDRESS at address: 0x016b7000
0xffff8824 in ___memcpy () at
/System/Library/Frameworks/System.framework/PrivateHeaders/ppc/cpu_capabilities.h:189
189    
/System/Library/Frameworks/System.framework/PrivateHeaders/ppc/cpu_capabilities.h:
No such file or directory.
        in
/System/Library/Frameworks/System.framework/PrivateHeaders/ppc/cpu_capabilities.h
(gdb) 


Backing up to frame 1 (Objects/stringobject.c:80), I
can see that "str" is not "size" (11070) bytes long,
but actually less:

(gdb) print (long) strlen(str)
$31 = 5755


When I backup to frame 2 (extensions/pyexpat.c:1089), I
can can see that:

(gdb) print size - offset
$34 = 5755


I think this works under Linux because Linux actually
allocates memory in larger chunks than requested or the
 overlapped area is not getting accessed......

it's in the tarball.  (if you're not able to download and unpack a tarball, you
won't be able to use library anyway...)

the LICENSE file can also found via the CVS archive:

    http://pyxml.cvs.sourceforge.net/pyxml/xml/LICENCE?view=markup

but you'll have to verify that the text in that document matches the text in the
pyxml release you end up using.

It's pretty simple to port PySAX to 4Suite:

FIXED BY REINSTALLING python

CHANGED:
            $ ./configure --prefix=/usr/python
TO:
            $ ./configure --prefix=/usr


Build:

            $ ./configure --prefix=/usr
            $ make

            Python is always built as a shared library, otherwise
            dynamic loading would not work.

        Testing:

            $ make test

        Install:

            # make install

this means that you don't have the Python build files on your machine. 
try installing the "python-dev" package (or whatever it's called in your 
favourite package repository) before rebuilding.

Hi,

For a long time, on your web page
http://pyxml.sourceforge.net/topics/docs.html you have carried a link
to my page "Writing an application for a SAX-compliant XML parser", at
http://www.hobby.nl/~scaprea/XML/. This site is going away. Because
the document is so old, I do not want to republish it on my new
