I've come across this bit of code within an existing legacy script - not written by me

(my $pname,my $sname)=split / +/,$rname,2;
[download]

I'm wondering if it is functionally different to writing

my ($pname, $sname) = split / +/, $rname, 2;

Hi

I have this assignment

When a string comes with below content

01/LC-13/E10GbE-1,01/LC-14/E10GbE-1

It must take numbers 13, 1, 14 and 1, in order as indicated

And with this instruction is achieved

perl -le '@m = ( "01/LC-13/E10GbE-1,01/LC-14/E10GbE-1" =~ /./\w+-(\d+)
+/\w+-(\d+)(?=,./\w+-(\d+)/\w+-(\d+))/); print for @m'
[download]

But when string comes with

01/LC-13/E10GbE-1

It must take numbers 13 and 1

And when I run my example does not work

$ perl -le '@m = ( "01/LC-13/E10GbE-1" =~ /./\w+-(\d+)/\w+-(\d+)(?=,./
+\w+-(\d+)/\w+-(\d+))/); print for @m'
[download]

It does not return anything

Which seems to be the trouble?

I don't know much about regular expressions

Regards.

Hi Monks, What is the best way to escape special characters like @, in username and password which is passed to the ua->proxy while using LWP::Useragent.
I tried using URI::escape but it doesn't seem to be working.
Thank you.

please help me! thanks.

This is a follow on from the second part of the question I asked in CGI::Carp fatalsToFile
The collective wisdom of The Monastery solved the first issue but not the second...it seems they are unrelated!

I am getting 500 errors intermittently from most, if not all of the pages of a website. The errors seems to be clumped together over time. In other words, once an error happens it seems likely that it will happen again quite soon. Whereas at other times we go quite a while without errors.

Every script has use CGI::Carp qw(fatalsToBrowser); at the start of the script.
The bit I am most confused about is that my understanding is that, with fatalsToBrowser the only two ways to get a 500 error is that the script has the wrong permissions or that the script doesn't return valid HTTP headers. As this is an intermittent problem, it is neither of these.

This is the code of the modules that are common :

package Site::HTML;

use strict;
use warnings;

use DBI;
#use DBD::mysql;
use Exporter;
use Template;
use MIME::Lite;
use Digest::SHA qw(sha256_base64);

use cPanelUserConfig;
use Site::Variables;
use Bod::CRM;

our @ISA = qw(Exporter);
our @EXPORT = qw(%data %file %cookie $dbh $current_user);

our $site = $Site::Variables::site;
our $template = Template->new(
    INCLUDE_PATH    => $Site::Variables::template_path,
    PRE_CHOMP       => 0,
    POST_CHOMP      => 1,
);

our (%data, %file, %cookie, $dbh);
our $current_user = 0;

my $crm = Bod::CRM->new($Site::Variables::env_crm_env);

# Untaint ENV{PATH} for MIME::Lite
my $path = $ENV{'PATH'};
$ENV{'PATH'} = undef;
foreach my $p(split /:/, $path) {
    if ($p =~ m!^(/(usr|bin).*)!) {
        $ENV{'PATH'} .= ':' if $ENV{'PATH'};
        $ENV{'PATH'} .= $1;
    }
}

package Site::Wayfinder;

use strict;
use warnings;

use cPanelUserConfig;
use Digest::SHA qw(sha512_base64);
use Facebook::Graph;
use GD;
use Bod::CRM;
use Site::HTML;
use Site::Point;

my $crm = Bod::CRM->new(Site::HTML->crm_env);

sub new {
    my $class = shift;
    my %attrs = @_;
    
    $attrs{'error'} = '';
    $attrs{'fb'}    = Facebook::Graph->new(
        app_id          => '12345678',
        secret          => 'abcdefghijklmnop',
        postback        => "https://$ENV{'HTTP_HOST'}/?command=authori

    );
    
    return bless \%attrs, $class;
}

My only hunch is that, because errors seem more concentrated at certain times, it is connected with the number of concurrent users. This in turn makes me wonder if is is Facebook::Graph that is the problem as it is deprecated. We only use Facebook for authentication. Users can create an account using Facebook rather than creating a password or can sign into an existing account using Facebook provided the email addresses are the same. This works under normal circumstances.

It isn't just web browsers that are getting the error. Facebook is complaining that our privacy policy page is giving errors and Stripe gets occasion webhook errors.

I am unable to replicate the problem on our test site - it only seems to happen on the live production site. Therefore I am limited on how much I can test or what I can tweak!

Any ideas what I can do to try and get some understanding of what is going on?

UPDATE: - to test my hunch that it is to do with multiple users, I have tried to cross referencer 500 errors with the data collected by Google Analytics and Hotjar. But the errors are not written to the Apache error log so this is proving difficult. I have started having Google Analytics open when I access the site so that I can look at the real time data when I next see an error.

Been a while since I have posted as OP with the Perlpocalypse and all. I took a tour "out there" to see what else was going on. I worked a bit with python, but, as a guy who started comp sci in the punchcard era, I can't look at fixed form source and call it "progress." (Do they have pythontidy like we have perltidy?)

I also took a gander at Usenet. It was nice to see some old names, but it has the same cooties of spammers and pornographers that mutate faster than one's killfile. comp.unix.programmer was still viable, as well as comp.lang.fortran, but I couldn't figure out the proprietary client the provider wanted me to use, so that fizzled out. (That's a nice way of saying I got locked out of my own account with failed attempts.)

I've had several scripts that I've been fiddling with in the meantime. This one came up in the context of Moon phase on historical events. I present attempts to iterate over the closed interval of a lunar cycle within the methodology of DateTime. It's not complete, but I've got output I don't understand, so I want to put it up for review. Let me just get source out there first:

$et is to be the second at which the moon and venus conjoin, ie, have the same right ascension. The problem is that I check the data with John Walker's Fourmilab ephemeris and use the option for univeral time. The time defined in perl thus:

is inputed without the T, and with the radio button activated, thus:

But that's not our value to check, which should be $et, namely:

It would seem that the moon is well past Venus by the margin of almost 2 hours. I tried to spitball if it might be using a different idea of coincidence with non-point masses. The full moon is about a half a degree. It's certainly not half full, and the dark edge hits venus first. In the prelims, I calculated that angle the moon moves through in a day to be 12.2 degrees. A quarter of a degree takes the moon about a half hour. Our answer seems to be at least 3 times out of this range as fourmilab has the conjunction between this interval, I:

And this time:

Q1) Do these bodies conjoin at $et or in the interval I? How does perl represent the moon in Astro::Coords? (For example, is the right ascension that of the center?}

I didn't expect $phases[0] to be negative. Given that it was defined by

Q2) How do I take $dt and $phases[0] and get epoch time?

Q3) How do I get the duration of the program run to display correctly? I thought I followed Dave Rolsky's example.

I wanted to be able to calculate the duration of the transit of the moon from venus to jupiter before it happened.

Thanks for comments,

>Greetings, I am attempting to reconstruct a post (using WWW::Mechanize and LWP::UserAgent so far) in order to upload a file and navigating some things I'm unfamiliar with. All my reading into examples has led me to the following code. I've truncated to the relevant section. I am having no issues with my first request to Authenticate and populate my $auth_key value with a previous request.

#!/usr/bin/perl -w
use strict;
use IO::Socket::SSL qw();
use LWP::UserAgent;

my $url_fw_upload='https://xxx.xxx.xxx.xxx/local/fwLoad?X-Progress-ID=
+xxxxxxxxxxxxx';

my $ua=LWP::UserAgent->new(ssl_opts => {
    SSL_verify_mode => IO::Socket::SSL::SSL_VERIFY_NONE,
    verify_hostname => 0,
}); 
$response=$ua->post($url_fw_upload,
    Authorization=>"Bearer $auth_key",
    Content_Type=>'form-data',
    Content => [
        "file" =>['firmware.img' => '/home/user/firmware.img'],
    ],
);
[download]

So the thing which is new to me is "fwLoad?X-Progress-ID", which is a Javascript generated UUID for file upload progress. I've used the same UUID that I grabbed from a browser debug session, within that browser debug I also have after the Request headers and before the Request Payload "Query String Parameters" with "X-Progress-ID: xxxxxxxxxxxxx". Since I have no Javascript capability here I'm trying to get around this and not sure if I even can without full Javascript functionality.

The results are always the same, 400 bad request. Any suggestions to point me in the right direction would be welcome as I've come up blank in my searches so far.

Hi Monks,

How Akamai authentication can be implemented using IMAP::Client (maybe) which would authentication both IMAP creds and Akamai creds (two-factor authentication),so that mails would be processed as expected.
Currently we have $imap->user and $imap->password methods used to authenticate user, how to add additional layer of authentication ?

Any help regarding this would be appreciated.
Thank you.
