Hi all,

I recall someone mentioning an issue where a Linux system was ignoring
use of the zero key on the user's keyboard. I have personally seen
this with a VMware image that was moved from another system with a
different keyboard type but I believe someone else remarked on a
similar situation recently under different circumstances.

We have a user who seems to have hit the same issue. If anyone can
shed light on this strange problem, it would be very much appreciated.

Okay, usual information that's always required with a problem repost.

What OS and version?  What connection method (telnet, console, ssh
etc) ?  How is the problem seen (TCL, SED, INPUT etc)?

Hi Ashley,

My query was deliberately vague as I don't know who saw it before or under
what conditions.

For the user that has hit the problem now, all I know is that it is some
form of Linux system running under VMware. Further information provided over
the weekend says that the problem only happens in an SSH connection and only
inside QM, not at the shell command prompt. This tends to suggest that it is
in some way connected with the specific API used to read the data (the
read() function in this case).

I have personally seen this with UV on a VMware system in the past. What I
am looking for is some suggestion of why it happens.

Thanks.

I'll happily take a look at the problem, both to replicate the issue,
and also to debug the code.  But I do need to know what "some form of
linux" is specifically.  Also, it would be good to know what versions
of QM the problem has been seen with.

C'mon Martin.  You know better than to ask vague questions. :-)

Further information provided over

I would think that some part of the read logic is doing the C equivalent of:-

input s,1
if s then string := s

Which should be rewritten as

input s,1
if len(s) then string := s

Otherwise "0" will be discarded .

I suspect that there may be a problem with the casts in linuxio.c, but
that's just a wild guess at the moment.

This tends to suggest that it is

Hi Ashley,

Thanks for the offer of help but we can debug the problem directly with the
customer. My reason for posting the query was simply that I recall seeing
this being mentioned recently somewhere. Perhaps it was not even in the
context of QM at all as I have seen it with UV. I was just hoping that
someone would know the answer without needing to do any research.

Okay, well do come back if you hit a roadblock.  I've got several test
systems that I can inflict it on.

If you do find the bug, I'll be interested to know where it is.  Can
you keep us informed?

Hi Ashley,

Will do.
