Summary: xml.sax second time file loading problem
Initial Comment:
Platform: windows 2000 SP2 (Pl)
Python version: Python 2.2 (#28, Dec 21 2001,
12:21:22) [MSC 32 bit (Intel)] on win32
I have noticed strange problem while using the xml.sax
module. When I run my application using python.exe
everything is working fine, the error occures only when I
try to execute my script using pythonw.exe.
The problematic code looks approximately like this (It's
a PyQT based application btw):
parser = xml.sax.make_parser()
handler = MyAppDocumentHandler()
parser.setContentHandler(handler)
try:
self.parser.parse(fileName)
except IOError:
QMessageBox.information(None,"MyApp","Sorry,
problems occured while loading:\n"+fileName+"\n\nIO
error:\n"+str(sys.exc_info()[1]))
return FALSE
except:
print "Unhandled exception:", sys.exc_info()[0]
QMessageBox.information(None,"MyApp","Sorry,
problems occured while
loading:\n"+fileName+"\n\nParser error:\n"+str
(sys.exc_info()[0]))
return FALSE
The first time when I open the file everything works ok,
the file is parsed, but when I try to open another file I
catch the IOError [Errno 9] Bad file descriptor error. (The
file location and everything else is ok.)

Deprecated. Reopen only if still happens in 2.3 or newer.

Please, could you verify if this problem persists in Python 2.3.4
or 2.4?
If yes, in which version? Can you provide a test case?
If the problem is solved, from which version?
Note that if you fail to answer in one month, I'll close this bug
as "Won't fix".
Thank you!

Hi Martin
No. I'm affraid no. It happens even if it is the only one
and the first application that is running on the system
(except background ones). It is verry unpredictible, I have
tested it once again and I have noticed that the smaller and
verry simple xml files (2k) were loading without problems
and the the error occured only while loading the bigger ones
(37k). At the same time yesterday the problem occured while
loading smaller files too. Maybe it is a memory management
problem?

Is there any chance that when you run the application the
second time, that the first instance is still around? Please
use the process viewer to find out whether there are any
remaining Python processes - this could be a sharing violation.

Correction to the previous bug message:
the 5'th line of the example should of course look like this:
parser.parse(fileName)
not
self.parser.parse(fileName)
The bug is still actual (the literal mistake took place only
in the bug report message)
