SQL Server XML data fields over a certain length produce MemoryError #239

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Create table in SQL Server (testing on 2008 R2) with an XML data type of 
length unlimited
2. Populate field with a large amount (512K-ish?) worth of data
3. Establish a connection to the database and attempt to .fetchone() one of the 
records from that table. 

What is the expected output? What do you see instead?
I expect to see the XML output. Instead I get:
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
MemoryError

What version of the product are you using? On what operating system?
Python 2.7.2 (32 bit) with Pyodbc 3.0.2 on Server 2008 R2 SQL Server 2008 R2.  

Please provide any additional information below.

I still haven't been able to narrow down exactly how big the XML has to be to 
trigger the issue. I have re-tested on 64bit and I don't get a MemoryError, 
instead I get an APPCRASH. Willing to test or provide any additional 
information needed.

Good catch.  Fixed in 3.0.6-beta07

I've added XML unit tests to the SQL Server file.
