[Samba] Controlling smbclient from python weirdness

May be completely unrelated, but does anyone know if the latest
smbclient forks a child which returns the file list to stdout, and then
the parent writes the prompt to stdout? I was once in a situation where
multiple children took turns writing to stdout. The output was correct
if I ran the file by itself, or if I captured the output using 'script',
but piping stdout to a file caused the output to be all out of order.
It may be completely unrelated because this was in minix, but it may be
a place to start looking. CVS access is firewalled off here :(, so I
can't check the src myself.

Subject: [Samba] Controlling smbclient from python weirdness
I've written a python wrapper around the smbclient program, so that I
can list/upload/download from Windows shares.
Using smbclient 2.0.9 or Version 2.2.5-2 for Debian, my wrapper works
well and is able to control the smbclient process via pipes well. With
both smbclient 2.999+3.0cvs20020723-1 and 2.999+3.0.alpha20-3 (on a
Debian box) the smbclient responses appear to be not always BEFORE the
new smbclient command prompt. I expect this kind of behaviour:
smb: \> ls
Ranger D 0 Tue Nov 20 12:45:40
2001
telix D 0 Tue Nov 20 14:56:28
2001
DOS D 0 Tue Nov 20 14:57:32
2001
65526 blocks of size 32768. 65526 blocks available
smb: \>
But with the more recent smbclient versions I get this:
smb: \> ls
smb: \>
Ranger D 0 Tue Nov 20 12:45:40
2001
telix D 0 Tue Nov 20 14:56:28
2001
DOS D 0 Tue Nov 20 14:57:32
2001
65526 blocks of size 32768. 65526 blocks available
And once I saw this:
smb: \> ls
Ranger D 0 Tue Nov 20 12:45:40
2001
telix D 0 Tue Nov 20 14:56:28
2001 smb: \>
DOS D 0 Tue Nov 20 14:57:32
2001
65526 blocks of size 32768. 65526 blocks available
As I look for the command prompt to know smbclient has finished giving
me the reply, this messes things up.
I control smbclient via popen4() in python2.1. I've found this strange
placement in the prompt to be the reason my code isn't working, via
running smbclient like this:
c = popen2.Popen4("smbclient //machine/c -N | tee /tmp/smb_out.txt)
And watching smb_out.txt (Popen3() acts the same way).
Is this likely to be an issue with how python talks to the process ? I
have not included a test case in this mail because it would make it
longer than it already is, but can provide one.
Note that when I talk to the smbclient myself (via starting one from a
shell) it appears to act normally.
Is there anymore information I could provide to help find out why this
occurs ?
Thanks,
Nick
