Subject: [ANNOUNCE] DBD::RAM 0.07
Message-Id: <5kaX4.56979$g41.2379916@news-west.usenetserver.com>
A new version of DBD::RAM is ready and has been uploaded to CPAN. It is
also available at
http://www.vpservices.com/jeff/programs/dbd-ram.html
This is a major version with many changes and additions. If you are at
all interested in the module, please upgrade.
This module allows you to treat Perl data structures and many kinds of
files as databases and to access them via DBI and SQL commands including
the ability to search and sort on a flexible range of criteria as well
as ability to insert, delete and modify records and tables. You do not
need an rdbms system or separate server to work with these databases.
Supported file types include fixed-width record files, XML files, many
kinds of "delimited" files (Comma Separated Values, Tab and Pipe
"delimited" files, Name=Value .ini files, etc.), and user defined files
which can contain data structured in almost any format. Support is also
included for MP3 music libraries and for accessing files remotely via
HTTP or FTP.
Changes to the current version include:
* Greatly expanded support for XML and for User-Defined formats
* Added export() method to allow saving tables directly to disk
files in many formats including CSV, Fixed-width and XML
* Expanded capabilities of continous file access with catalog()
* Added remote-file support via LWP for additional file formats
* Added ability to specify alternate field and record separator
patterns
* Added convenience names TAB and PIPE to support shortcuts for
tab and pipe "delimited" files.
* Modified and standardized the import() syntax
* Greatly expanded POD documentation
Enjoy, and please send me your comments/suggestions/gripes, etc.

I think this might need to be emmended to "an *ASCII* string that
looks like an identifier". Even using locale, I've found that Perl
won't auto-quote non-ASCII characters in hash keys:
#!/usr/bin/perl -w
use strict;
use POSIX;
use locale;
POSIX::setlocale(POSIX::LC_ALL, "catalan");
my %hash = (València => 'Universitat de València');
print for keys %hash;
----
Unrecognized character \350 at C:\www\perl\modules\posix\locale.pl
line 7.
Quoting 'València' corrects the problem.

Then why are you using Perl at all?! The same people that wrote and/or
vetted those very useful diagnostics you distrust, are the same people
that wrote and/or vetted the rest of the Perl compiler and (post-compile)
interpreter. Even more people have contributed to the Perl standard
modules: have you replaced the entire set with your own code, so you
can trust that? Have you replaced Perl's executable with one you
wrote yourself?
Ahah! We have it! The beast is running its own Perl, one that it
wrote itself and so can trust. Of course, the rest of us have seen
enough to know that its code can't be trusted, even if we didn't know
its "perl" was broken (e.g. it doesn't support "perl -ne").

You haven't. The <> operator reads in line by line (or record by record,
if you've set $/ to record-read mode). It must, of course--the individual
elements of an array read in like:
@foo = <FH>;
are lines, just the same as you get reading them via:
while (<FH>) {
}
They'd have to be, otherwise the program would function differently
depending on whether you read in the data line by line or in one slurp.

No. The risk is the same. Your exposure is greater, but the risk is
identical.

I say always use lock. If you're reading in a file that someone else might
be changing, then lock it. Always. Otherwise you may get crap data. If
your data is important enough to use, it's important enough to protect. If
it's not important enough to protect then you might as well just generate
random characters.

There aren't any. The code's not particularly simple, but neither has
anyone made any attempts to hide anything. Diving into the core code's not
a bad thing to do.

Bad. Very bad. In general you (this is the generic you, rather than a
specific you) shouldn't do this. Humans inevitably make assumptions (and
I'm working on my assumption that you're human, despite the e-mail
address, as very few giant fire-breathing lizards post to Usenet) but you
should *not* put forth those assumptions as fact. You (this is the
specific you now) may well have been misled by other people doing this.

It may (and this is a *big* may) use less wall time, depending on the load
on the system. It will use more CPU time, however. For files of that size
you're operating pretty much completely out of OS and stdio buffers,
though, so odds are you'll actually run slower in both wall and CPU time.

It is what happens.

You should, definitely before making pronouncements of efficiency or
quality to the public. The Benchmark module is your friend here--it makes
benchmarking most things easy.

Ummm... you're proposing this:
@foo = <FH>;
foreach my $line (@foo) {
}
is less coding than this:
while (my $line = <FH>) {
}
I think I'm missing something. If you're talking about this sort of thing:
@foo = <FH>;
for ($index = 0; $index < $#foo; $index++) {
my $line = $foo[$index];
}
Then I'll *definitely* disagree.

While with a filehandle won't lead to an infinite loop--it can't. Sure
some syntax errors may lead to program misbehaviour, but that's always the
case. That's why we all debug our programs before releasing them for use,
right? :)

Sure. But I was only addressing this one particular circumstance. In this
case, file-slurp's decidedly suboptimal.
> To promulgate absolute non-use of slurp,
> seems very poor advice.
You're way over-generalizing here. Slurping in a file you'll be processing
line-by-line is a waste, and should be avoided, which is what I said. If
you'll be operating on the file in other ways (using the data multiple
times, skipping around a bunch, stuff like that) then slurping makes the
programming easier and less error prone. (Possibly faster too)

Check the value of $ENV{HTTP_USER_AGENT} in your script.
Both Netscape and Internet Explorer claim to be "Mozilla". MSIE 5 even
claims to be a Mozilla v.4. You definitely need to interpret the data
between parantheses. But that gets too far off-topic for this newsgroup.

See "perldoc CGI", look for the user_agent() method.

Browsers often lie though. Some might even try not to
identify themselves. Spam harvesters might pretend to be
Netscapes. So while you can check for the agent's ID
don't forget it might be wrong. Nor indeed, forget a
catchall for "other" browsers.

This is not a perl question, it's a CGI question.
As the CGI-Programmer's FAQ (http://www.webthing.com/tutorials/cgifaq.html)

Hi,
With the necessary caveats mentioned in the other responses,
you may want to check out the HTTP-BrowserDetect distribution,
under $CPAN/authors/id/L/LH/LHS/ - this can also parse some
additional information from the browser that may be useful to you.

Best way I have seen for Browser Detection is an ASP(Active Server Pages)
module called "Browser Hawk" http://www.cyscape.com/products
Probably only viable for Win32 although ASP for Unix is now available
somewhere.
Definetely worth a look in my opinion ASP does a few things better then Perl
can and vice-versa using both can make life a lot easier.

I have a script that creates directories for a web base application as

The problem is that those newly created directories get the username and

When I try to access information contained in those "nobody" directories
from a web browser it cannot be accessed or in some occasions I get a server
error.
Is there a way to code the directory creation in the Perl script to avoid
that perhaps by providing a username other than nobody or is this a server

You need to run Apache (which I assume you're using) as user www - in my

It's a terrible tool if you have any SSI's, CGI's or other

Subject: Is anything planned re: Perl error reporting?
Message-Id: <8gjdqo$a6g$1@nnrp1.deja.com>
I am mightily impressed with Perl 5.6.0. The addition of Unicode is a
really excellent idea. I am wondering, though, how much longer it will
be before Perl error reporting gets overhauled. I have raised this
issue before but gotten an oddly unsympathetic response.
Specifically, it seems logical to simply report the line number in
error on the basis that you can just fire up vi and go to the line, so
that's what Perl does. Unfortunately this breaks down utterly and
completely when you deal with dynamically evaluated code, especially
code that is being created server-side in a Web environment. The 'line
number' is often meaningless, making it painful in the extreme to track
down the problem. If the evaluated code is at all complex (e.g when
using mod_perl) then debugging reduces to desk checking for syntax
errors and the inclusion of print statements. Surely we don't need to
go back 40 years to debug Perl code!
I believe Perl desperately needs contextual error reporting (at least
during the compile phase), similar to that provided by most compilers
and interpreters. Such as
use strict 'vars';
print $foo+1;
^ undeclared variable $foo
Consider the rather silly mistake made in this snippet of code
eval("print 1; .
"print 2;");
which results in the following
syntax error at err.pl line 2, near ""print"
(Might be a runaway multi-line "" string starting on line 1)
Can't find string terminator '"' anywhere before EOF at err.pl line 2.
Now this is a silly example but in the real world tracking down that
sort of silly mistake in complex code, with dynamically evaluated code
that might well come from a web server, makes for a real hassle.
Whereas if Perl could report
eval("print 1; .
^ missing string terminator
"print 2;");
then I submit finding this sort of thing would be a good deal easier.
I appreciate that Perl tried hard to explain its thinking here, but
imagine that this evaluated code was buried deep inside a whole bunch
of inter-module calls and so on. Now those line numbers become pretty
meaningless, so finding the error becomes much harder.
Since most other compilers and interpreters report errors in context,
why must Perl continue to be so different?. What do other people
think?. Is there any possibility Perl error reporting might be changed
in the foreseeable future?
As a comparison, let's let the Sun Java compiler loose on code with a
similar error
class hello {
public static void main(String[] args)
{
String s;
s = "hello +
"goodbye";
}
}
as you see, the string is unterminated in the same way as it was with
the Perl code. And the compiler reports:-
test1.java:5: String not terminated at end of line.
s = "hello +
^
test1.java:6: ';' expected.
"goodbye";
^
2 errors
See what I mean. You get the same behaviour from the reference
Javascript compiler, too. Why must Perl march to the beat of a
different drum?

Sure, use the CPAN module. An interactive way is
perl -MCPAN -e shell
cpan> autobundle
takes a snapshot of your system and puts it in
$CPAN::Config->{cpan_home}/Bundle
Okay, so it also includes standard modules, just grep -v them :-)
read the CPAN manpage, it might help.
AFAIK, there is no way to tell if a module came with the standard
distribution, since they are _modules_ and perl should be able to run
without them (they're just there because just about everybody wants
them :-)

Here's a handy tool that will let you look over the list of
installed ("in the path") modules as well as other information,
using your browser (so it's not as useful if you are at a
command prompt):

I have the same issue except I need to specifiy a user name and password to
get outside of the proxy for HTTP requests. I read a bunch on LWP and proxy
but did not see anywhere to specifiy credentials to get outside of the
firewall. Does LWP have a way to do this? Thanks, harley.

This seems to work for redirecting to the webpage that called the CGI for anyone
who's interested:
use LWP::UserAgent;
$ua = new LWP::UserAgent;
$ua->proxy(http => 'http://proxy.server:8080') ; # Obviously yours might not be
8080
print "Content-Type: text/html\n\n";
$url = 'http://www.yahoo.com/' # etc. etc.
my $req = new HTTP::Request ('GET', $url);
$page = $ua->request($req)->as_string;
$page =~ s/^.*<HTML/<HTML/si ; # chopping off headers (there's prob. a better
way)
print $page;

Take a look at this:

A possible solution??

Are you working on Windows, as your headers suggest? If so, just read
the Activestate FAQ about sending mail from Winxx.
Finding the FAQ ->**on your hard disk through the start menu**<- will
help you infinitely more than just getting a quick answer to this
specific question.

Message-Id: <null>
Administrivia:
The Perl-Users Digest is a retransmission of the USENET newsgroup
comp.lang.perl.misc. For subscription or unsubscription requests, send
the single line:
subscribe perl-users
or:
unsubscribe perl-users
to almanac@ruby.oce.orst.edu.

To submit articles to comp.lang.perl.announce, send your article to
clpa@perl.com.
To request back copies (available for a week or so), send your request
to almanac@ruby.oce.orst.edu with the command "send perl-users x.y",
where x is the volume number and y is the issue number.
For other requests pertaining to the digest, send mail to
perl-users-request@ruby.oce.orst.edu. Do not waste your time or mine
sending perl questions to the -request address, I don't have time to
answer them even if I did know the answer.
