| The below script produces a '[Errno 9] Bad File Descriptor' when
| executed. If I remove the try: except: statements, the script stops when
| the error occurs.
|
| The purpose of the script is to monitor the size of the three main logs
| on a Windows 2003 server and send and email should any of the logs get
| shorter. It works fine... just don't know *why* it produces the '[Errno
| 9] Bad File Descriptor' error.
|
| I'm running Python 2.4.1 on Windows 2003 SP1 Server with no funky win32
| extensions ;)

| logs = ['AppEvent.Evt', 'SecEvent.Evt', 'SysEvent.Evt']
|
| app_size = 0
| sec_size = 0
| sys_size = 0

| def send_email(LogName, old_size, new_size):
|     f = "Somebody<XXXXXXXXX at vt.edu>"
|     t = "Somebody_Else at vt.edu"
|
|     msg = MIMEText("""old_size = %d, new_size = %d""" %(old_size,
| new_size))
|
|     msg["Subject"] = "%s Log Just Got Shorter" %LogName
|     msg["Message-id"] = email.Utils.make_msgid()

|
|     h = "smtp.vt.edu"

|     s.sendmail(f, t, msg.as_string())

|
|         try:
|
|             a = os.stat('C:\WINDOWS\System32\config\%s' %log)

Without looking at the rest of script:

Try using either escaped backslashes as in:

a = os.stat('C:\\WINDOWS\\System32\\config\\%s' %log)

or a raw string (as long as it doesn't end with a single backslash) as in:

a = os.stat(r'C:\WINDOWS\System32\config\%s' %log)

or simply use forward slashes as in:

a = os.stat('C:/WINDOWS/System32/config/%s' %log)
