Actually you can go further back than this. GCC's had its own set of
extensions to C that were far more significantly off-spec than anything M$
ever did to Java. It could handle the standard code of the day (either K&R
or ANSI, depending on when you look) but had a number of language
extensions that'll get you non-portable code if you use 'em.

I was mainly referring to the wobble on undocumented features, and on
those bits that are only partially or not strictly documened.

Assuming the proponents of standardisation get their way, is there any
way we can 'rig it' to _prevent_ third parties from developing their own
compilers, which support their proprietary extensions, and plunging us
into a siuation akin to the web?
Specifically, and bluntly, is there a way to stop MICROSOFT from humping
the camel?
I see absolutely no reason why compiler extensions should be allowed at
all. If a company wants added functionality, they can simply put it in
a module (Perl, C, precompiled, not, whatever).
Is this doable?

Ok, so multiple precendents have been set. Third-party compilers
clearly get abused.
How can we make sure this never happens to Perl?

If there's a module which does what you want, it should be listed in the
module list on CPAN. If you don't find one to your liking, you're welcome
and encouraged to submit one! :-) This sounds useful, and you should
probably not make anything web-specific about it. Don't neglect the info
about validating data from the FAQ.
Hope this helps!

You must mean _not_ getting delivered! :-)
Probably the bounce message is going to someone else - whoever is the real
sender, according to your mail system. If you're doing this over the web,
this may be user 'nobody'.

If you need help in understanding your mail system, perhaps you should
search for the docs, FAQs, and newsgroups about e-mail. Cheers!

That's not what I see happening. Could you check again?
But, to be certain, try writing up a static regular expression and string
which don't (or do) match contrary to your expectations, then post your
simple sample code here. It should be no more than five or six lines long,
which will make it easier for someone else to see what's going on. Cheers!

I'm assuming you didn't expect the 3rd and 4th to match.
The 1st matches when your code is executed on 5.005_03 on Linux.
I think we need more detail on your installation.

What is that last line doing? Creating a hash where the keys eq values? You
probably meant:
$order{$_} = $_ for @order;

/^(?:[^$x]*$x){6,6}($order{shipname}$x$order{shipaddr1}$x$order{shipaddr2})/

Why use a hash? Can't you just write shipname instead of $order{shipname}
since they are going to give the same result?
Please post again when you have prune away all irrelevant bits and are left
with the minimal lines of codes that still exhibits the problem you
encountered. I tried debugging your script, but it gave me a headache wading

Looks like a bug to me.
Match fails with 5.6.
Match succeeds with 5.005_03.

If your news administrator still carries comp.lang.perl, please let him
or her know that that newsgroup has not existed since 1995. If you
have such an outdated newsgroup listing, you are probably missing out
on many other valid newsgroups as well. You'll be doing yourself and
many others a favor to use only comp.lang.perl.misc (and other valid
Perl newsgroups) instead.

If you're following the proper protocol but some browser or server doesn't
cooperate, then it's the other program's fault. If you're not following
the protocol, then it's your fault. If you aren't sure about the protocol,
you should read the protocol specification. If you've read it and you're
still not sure, you should ask in a newsgroup about the protocol.
Hope this helps!

regardless of whether you got his question right that is evil (not eval)
code. eval is not meant to get around symrefs and symrefs are bad
enough. if you are demonstrating this it could mean you write code like
that and you shouldn't. use hashes and stay away from symrefs and only
use eval when truly necessary.

It is an incredibly bad idea. It is the only way to make the problem
even worse.
It still amazes me that people can continue to miss the point here.
``Hi, you shouldn't leave your windows unlocked when you go out,
someone might come in and steal your stuff.''
``Oh. Well, how about if I leave the door open with a big sign that
says OPEN DOOR HERE PLEASE COME IN AND ROB ME? That should be safe as
long as I lock the windows right?''
The problem with symbolic references is that they use global variables
in a totally unconstrained way, and you end up having an effect on
your program that might not be what you expected. For example, you
might end up setting $* by mistake, and then all your regexes break.
Or you might set $/ by mistake and then all your file input goes wacky.
But at least you know that whatever disaster occurs, it will be
related to the unexpected modification of some global variable. It is
not, for example, going to immediately erase your entire hard disk.
When you use 'eval', you do not know that any more. You have all the
sanme old problems, multiplied by 1000, because the code could be
doing absolutely anything.
Don't you folks drive? Didn't they teach you in driving school that
you have to drive defensively? That is, when you drive, you don't
assume that the other drivers are going to any everything right? When
you drive, you try to plan for the worst case: What if the guy in
front of me comes to a sudden stop? What if the car coming the other
way at the next corner *doesn't* stop at the stop light? What if the
lady on the on-ramp *doesn't* yield to oncoming traffic? You drive as
safely as you can so that when the inevitable mistake occurs the
damage is minimized.
Using 'eval' here is like driving a seven-ton gasoline tanker with
your eyes closed. In principle, it's just like driving a Yugo. In
practice, when something goes wrong, four hundred people die in a
flaming inferno.

Here your keys happen to be safe. What will happen when someone adds
a key that contains a hyphen? What will happen when someone adds a
key that contains a period? What will happen when someone adds a key
that contains a space?
That is a rhetorical question. You can't answer, because you do not know.

Might be. Perhaps you need to check the docs, FAQs, and newsgroups about
ASP to learn more.
OTOH, you may want the Expect module. I don't know how you log in to ASP,
so that may not work for you.

Always? Did all of the tests in 'make test' work when you installed perl?
You should probably re-build perl and ensure that the tests pass before

Are you sure that it is perl doing this? Or is it the
application that is bus erroring? I.e. do you get a bus
error if you run this application from the command line
with the same set of arguments and environment?

And, even if you had used the correct filename, it's quite possible that the
reason for your problem is in the #! line at the beginning of the file. If
this doesn't point to an existing copy of the Perl binary, your script won't
run the way you tried to do it.

You can use the VMS::IndexedFile module off of CPAN to get a tied-hash
interface to your RMS file. If you need something fancier you're currently
out of luck as there isn't anything else at the moment.

If there's a module which does what you want, it should be listed in
the module list on CPAN. If you don't find one to your liking, you're
welcome and encouraged to submit one! :-) Hope this helps!

At some point, cmd1 should get a SIGPIPE when it tries to write. If it
isn't ignoring or handling that signal (which should be the default) it
should die. Could that be it?
Of course, if it's inherited by init, it won't become a zombie - init will
reap it at the earliest opportunity.
And why the complex exit+system combination? Wouldn't an exec do the job
as well? Or maybe I'm missing something.
Of course, you've also got a Useless Use of cat there, but that's not my
department. :-)

Subject: PLEASE HELP: Perl reading PDFs
Message-Id: <8i2uqn$43q$1@netnews.upenn.edu>
Hello,
OVERVIEW:
I have a simple Windows application(I guess written in VB) that can run a search on PDF files, based on a users input string. This windows application seems not only run a search on the text in the PDF, but the PDF parameters found in the "General Info" window. (To get to the general info window--- Open any PDF Document using Adobe Acrobat 3.0 or 4.0. Click on "File" >> "Document Info" >> "General". ) That is, the Windows application will search the "General Info" parameters like "Author" and "Keywords"
as well as the PDF text for a match.
PROBLEM:
How would I get Perl 5 to search PDF files for a match in the PDF text as well as the PDF general info parameters?
Thanks,
Mario

Go to http://search.cpan.org/ and look for "PDF". There's
a number of modules including one actually called PDF
which is probably what you want.

Read the perlsec manpage and other security documents until you change

Perl does not (generally) care about whitespace.
You can put newlines wherever you want to.
These are all the same, from perl's point of view:
print "line one\n";
print "line two\n";
print "line one\n"
; print "line two\n";
print "line one\n"; print "line two\n";
print
"line one\n"
;
print
"line two\n"
;

Someone wanted it that way.
You need to ask them why they chose that way.
Perl does not require/need it that way.

If you're wishing merely to _find_ (as opposed to write) programs,
this newsgroup may not be the best resource for you. There are many
freeware and shareware archives which you can find by searching Yahoo
or a similar service. Hope this helps!
