Does anyone know of a stable, well-featured commercial debugger for UNIX
(Solaris)?
Budget is reasonably large, but it should be closed-source please (so I can
persuade management to sign it off; they seem to have an aversion to open
source, even on things which have no contact with the outside world.)
Any pointers gratefully recieved.

perl has a debugger, albeit one withouth mouse support. Read the
perldebug documentation. If you want a point and click interface, DDD
has some perl support: last time I bothered to check it was fairly
primitive and slightly off.

Euhmmmm... If they have a problem withOpen Source, what do they think
perl is?
I don't think ActiveState's stuff works anywhere but under windows, but
if your budget is large enough, maybe you could get them to port it to
Solaris.
But I think you are out of luck if you want a well-featured commercial
debugger for Perl. I wouldn't even trust one. If it doesn't come with
Perl, or was developed by the Perl development team, it probably doesn't
get it right.
What's this obsession with GUIs anyway?

There's always Devel-ptkdb, a perl debugger written in Perl/Tk. Check
CPAN for details.
You could always write your own as well. I recommend the Tk-Text-
SuperText module for that approach.

Install Devel::ptkdb from CPAN and run perl -d:ptkdb.
You may want to ask the author to licence it to you under hevily
commercial licence if that's better with your company.

I guess this is your first script for Uploading files....the most
common error that most people commit is that they forget to mention the
Encoding types for the files....makle sure you have the following
statements in your form objects
<form name-xyz action-xyz.cgi enctype="multipart/form-data" >
and your File objects have
<input type="file" name="file_to_upload_01" enctype="multipart/form-

Subject: Problems saving an uploaded file.
Message-Id: <8vamnj$btm$1@newstoo.ericsson.se>
Hi all,
I am using Apache 1.3 together with ActiveState Perl 5.6.0.618 and I have
the following problem. I want to upload a file from a webpage and save it at
a server. I am using the following code to do that:
$bitfile = param("bitfile");
open (SAVE,">./bitfile.bit") || die $!;
binmode(SAVE);
while ( read($bitfile,$data,1024) ) {
print SAVE $data;
}
close SAVE;
What it does is that it takes the file handle and then saves the clients
file under 'bitfile.bit' on the server.
Sometimes this works, but many times it happens that the file is not saved
(it is created, but has size 0 or is only 1 byte long). I have enough space
on my disk and enough memory. Could this be a bug?

Hi,
I have a perl cgi scripts which should signal a running perl script. The cgi
script is running as user 'nobody' while the other script is running as user
'player'. This doesn't work since the cgi script is not the owner of the
process.
Is there any signal which I can send from the cgi script? Or can I allow not
owning processes to signal the running script?
Any other, easy way, to do IPC is welcome.

No. You can't. This has nothing to do with Perl, but is a feature of
Unix. You don't, after all, want just anyone's signals interrupting your
program, do you?
You could, if you ran the other program as nobody as well.
> Any other, easy way, to do IPC is welcome.
Several other ways: sockets, named pipes, SYSV message queues.
What is best, and how to solve it is impossible to say without knowing
much, much more about what your programs do, and what the intent of the
signal is.
It becomes less Perl as well, but post the specification here anyway.
There'll be good ways of doing this with Perl specific solutions, with a
bit of unix mixed in [1].
begin[offtopic]{crystal ball}
My crystal ball says that you'll either need the four argument form of
select, with a named pipe or sockets, or you'll need two processes
instead of one waiting for that 'signal', parent and child. In the
latter case, you can make the child block, waiting for the 'signal', and
let the parent continue doing what it needs to do. If the process doesn't
need to do anything until a 'signal' comes in, make it block on a read
from a named pipe, when the other process writes, the action can occur.
The perlipc documentation might help. If you have access to one, a copy
of /Advanced programming in the Unix environment/ will be helpful as well.

I would assume he got there by "writing something that was better
thrown away", then throwing it away and repeating.
Or maybe he got a copy of the Camel book and read it twice before
actually writing any Perl. That's what I did, and while it didn't
make me a good Perl programmer immediately, it did get me far enough
up the scale that I can still look at my first code and not wince.

I don't agree that you should start programming with perl. Its syntax is way
too "out there" for a new starter.
