Hi there

Im developing a 'groups' website - similar to Yahoogroups.

anyway... - One of the items im going to develop / enhance is a word-
search on messages...

Initially, message archives may have 2-5 messages - slowly growing up
to thousands of messages (each message stored in a txt file in a
particular directory..)

Question :-

Is it 'economical' - as in speed/time - server usage etc.. to

:- do a glob on a directory & open/search every file one after another

:- To periodically Create a word-database of all the messages & the
message number it pertains to..

:- is there another single-command, that I can use - to word-search
all the files in one go ?

:- anything i've not thought of yet...

Thanks..

G

How can i do that in Windows ? I don't want to wait the process terminate, to
continue interpreting the script.

I'll challenge the "written very well" from a technical standpoint.
In a few minutes of scanning, I see they are using hand-rolled
CGI parsing routines instead of CGI.pm.  That was fine in 1995,
but completely unacceptable in 2003.  Denial of service attacks and
security holes result from such code.

Just based on that, I'm scared to put those anywhere near any server
that *I* have an influence on.  You should do the same.

All,

I'm writing a script to parse out values from a string. The string
represents a range of document numbers. For example, PERL001 PERL005
represents the documents:

PERL001
PERL002
PERL003
PERL004
PERL005

Where each item in the list identifies a single document.

For each range, I need to parse the number at the end of the document ID.
Meaning for PERL020103 PERL020554 I want to get back 20103 and 20554. The
range's limits can be delimited by pipe, space, tab, comma, or dash. The
delimiter itself could have one or more spaces between itself and its
surrounding text. The text prefix could also be left off completely. This
means the following are valid:

PERL020103 PERL020554
PERL020554 |PERL020554
PERL020554 | PERL020554
PERL020554 - PERL020554
PERL020554,PERL020554
020554 020554

My brain is fried. Here is what I've tried. I welcome any suggestions.

#! /usr/bin/perl

use strict;

while(<>) {
	 print("Match: $`[$&]$' ($1 $2)\n")
if(/\w*(\d+)\s*[,-\|]*\s*\w*(\d)/);

}

Hi Randal:

Yes, you have the right to say how you feel, but I have used them on ALL my
customers web sites for the many years. Perl was supposed to be lots of ways
to do things, do it your way ... but it's authoritarian and hectoring behind
the smiles. No doubt like its founder. Executable line noise.

And now if any of them get broken in, you can no longer claim that
you've never been told that these programs have known substandard coding
styles.  In court, you would lose, and become a liable party and have
to pay damages.

It's not wise to ignore experts.

That's the reason I bring this up here.  If code is substandard, and
you choose it anyway, you run increased risk of financial and
reputation loss.  For that reason, I would condemn the programs from
that site... they're universally substandard, and so you use them at
your own risk.

For future reference a good source of free cgi scripts
is:

No I do listen to experts, but so many people say they are experts and they
all have different ideas .. if you are the expert (and I have read your
book) why don't you make it easy for all of us here and just say which
scripts are the best and which ones to use, then we would all know what the
experts know.

Show me something different, one you would use and then if I am taken to
court I can quote "an expert advised me on what script to use for a Form
Feedback".

He was not helpful - he didn't tell me how these denial of services would
occur, he didn't say anything about cgi.pm. He did not help. Just strutted
his stuff. Very macho. That is why so few females go into computing.
Basically I just felt like a flame!  attack, I think that would have helped
much more.

The NMS scripts are written by people I trust.  And since those
were already brought up here, I didn't want to repeat the information.

But being a lawyer, you apparently need the same thing read to you three
times.  There you go. :)

NMS has problems that is news to me perhaps you would
enlighten me on the problems with NMS scripts.

In regards to Randalls comments I think he was very
helpful, he didn't mention any particular problem with
the scripts, he just said that because they weren't
using cgi.pm there could be a problem, I am sure if
you hire his services he will do an analysis of the
scripts and itemise all the possible problems that
could occur.

For more information on cgi.pm

http://search.cpan.org/~lds/CGI.pm-3.01/CGI.pm

It is most likely the most well know perl module in
existence.

     Those of us who are used to Randal realize he is
socially challenged. When you see his signature on an
email, you need to read what he says and try to ignore
how he says it. Think of him as a drill sargent. A
genius at programming with deficient communication
skills. The stereotypical nerd. Have a little pity.

that does this already. Its drawbacks do not include
complaints about searching files this way.

     If they do, the files to be searched are not static

to avoid corrupting the database.


     Will message files contain just the "guts" or will

     If they are static (not user editable) and they
contain markup, a word-database would efficiently move
markup stripping to the message posting phase, allow
for faster searches and reduce redundant stripping of
markup.
     If message files are not static and they contain
markup you could still see a performance gain by
stripping markup at message creation (or edit). It
would depend on the number of messages and the
popularity of the search function.


: :- is there another single-command, that I can use

     Using a text file to hold a message has some
advantages. Using this method incorrectly has serious
drawbacks. Keep only the message in your files. Add
markup on the fly. Think about how difficult it would
be to change the web site design if markup was embedded
in a few thousand files.

     I had a client who had a 30,000 file limit. And we
went over that limit when updating messages for a site
redesign. It took us a while to figure out where the
error was.

     The better way to compare search efficiency is
probably through testing. Compare the speed of different
methods based on a small, medium, and large number of
messages.

??? Not even Mariam-Webster has any idea what's "sargent".
It knows WHO was one Sargent: 1856-1925 American painter; known
chiefly for elegant portraits of the Edwardian gentry; caused a
scandal with his portrait of famed Parisian beauty known as "Madame
X"

"Bing!" (From Groundhog Day, a great movie)

I don't treat the audience of this list as babies.  I figure that if
they want to know more, they can ask again for me to elaborate, or
write me privately and hire me to explain it to them (thanks for that
suggestion!), or spend 15 minutes googling for the extra information.

Otherwise, I'm not going to retype or cut-n-paste the same things I've
said here or elsewhere.  I say enough to nudge people in a useful
direction, then move on.  It's the old 80-20 rule in action.

If this is truely *not* useful, I think I'd be getting a lot more
hostility *everywhere* I go.  I don't see any public evidence for
that.

Although, I do take exception to the one who said I had no social
skills.  Perhaps you see me through your own filters of expectations
of me.  I was able to chat with someone about a year back who had
similar criticisms, and on reflection, he was unable to point to any
specific behavior he had *actually* witnessed.  He was instead passing
along and acting on an untested collective belief that I was rude and
crude, sort of a tribal mythos.  Perhaps you have a similar prejudice?

I didn't really ask to be a public figure, but I'm really sincerely
attempting to own up to the responsibility.  I welcome feedback, and I
do accomodate.

I think you just got rubbed wrong by Randal's straight forward writing
style.  Yes, perl encourages you to do things your way.  You have to
admit there are certain things that people have done which eclipse your
own abilities.  There's a reason why the script you pointed to is not
included as part of the Core distribution, whereas, CGI.pm is.

Certain individuals, doing things their own way with community support,
are capable of producing a quality product above and beyond a single
person's own abilities.

CGI.pm is an AWESOME example on an ideal BlackBox design.  Do you speak
native HTTP 1.1 ? If not, it is far better to leave this conversation to
CGI.pm who does. If you're a lawyer and a programmer, I doubt you've had
time to read through the relevant RFC's to be able to handle a
multipart/form-data POST from scratch which also includes query string
arguments? :)

TIMTOWTDI, but sometimes, one way is exponentially
wiser/smarter/easier/more comprehensive to use.

There is no excuse to NOT use CGI for standard cgi model web
programming, or DBI for database interfaces for that matter.
More work than you could reproduce in a lifetime is available to you for
free, no strings attached.  Plus, what happens when I want to provide
feedback and attach a picture of something?  Not an unrealistic request
in these days of increasing high speed connections.

Please, do _NOT_ encourage people to decypher query strings using that
archaic cgilib.pl style code block that makes me cringe.

Hello,
is it possible to serve a short video file in html page without
caching it? In other words, I want to show the video to the user,
but I don't want that the user can download it or retrieve it from
its cached files. Perhaps there is some way in cgi programming that
allows to show a video from the server, but that don't actually send
it to the client.

Thanks
D. Renzi

In brief, no.

To elaborate slightly... how do you think it is being shown, unless
it is also being *transmitted* to the client?

Well, there is a way. don't know if its what you're looking for, its
called "Streaming Video". Though, that's not a foolproof solution either
as there are a number of streaming video capture tools.

Ever heard of Real Networks? If this is a business thing, look there,
and probly Akamai.  Google a bit for "Streaming Video Servers" or
something along those lines.  Undoubtedly this will lock a user into
using a proprietary video format with little alternate OS support and
lesser quality than regular formats.

This is kind of a low hanging fruit problem as well.  If you have a
video, just disabling right click over the link maybe enough to deter
the most number of straight downloads.  People wise enough to look for
the video in Cache directories are also wise enough to search around for
DRM circumvention tools anyways.  If not search, create (very very very
very very very very small minority, but it only takes one).

Whatever the solution, its outside the scope of "normal" CGI problem.
Given that certain web browsers (*cough*MS IE*cough*) will ignore
caching directives of the HTTP Environment ("HTTP-Equiv: no-cache" or
something like that) AND the EXPLICIT preferences of the particular
user, it'd be all but impossible to prevent the movie from showing up in
the cache of the browser.

how do we use perl to check if a folder exists, if the folder exist,
then do not create a folder. however if the folder does not exist, then
create the folder.

Thanks

I would just create the folder regardless, and then ignore the "already
exists" error.  Otherwise, you're creating too much work.

You create folders (called "directories" in Perl's native tongue) with
"mkdir".  See "perldoc -f mkdir" for details.

Unfair... I said more than that. :)

At least you spelled my name as my mom does this time.

True, true. But I couldn't resist. 8-)

And yet, amazingly enough, I've never asked your mom how she spells your
