Hi! Asking for a wisdom here...
We have a module that modifies signal handler $SIG{__DIE__} to log information and to die afterwards. Hundreds of scripts relied on this module which worked fine in perl 5.10.1.
Recently we had the opportunity to install several Perl versions but unfortunately a large number of scripts that used to work with Perl 5.10.1 now behave differently:
- Failed in 5.14.4:
/home/dev/perl-5.14.4/bin/perl -wc
test.pl
RECEIVED SIGNAL - S_IFFIFO is not a valid Fcntl macro at /home/dev/perl-5.14.4/lib/5.14.4/File/stat.pm line 41
- Worked without changes in 5.26.3:
/home/dev/perl-5.26.3/bin/perl -wc
test.pl
test.pl
syntax OK
- Worked without changes in 5.38.2:
/home/dev/perl-5.38.2/bin/perl -wc test.pl
test.pl syntax OK
Many of the scripts can only be updated to 5.14.4 due to the huge jumps between 5.10 and 3.58; But we are stuck on that failures.
Was there an internal Perl change in 5.14 which cause the failures but works on other recent versions without any update on the scripts?
Cheerio!

Why I Like Perl's OO
I started programming with QBasic and later C. While it was difficult to learn those languages back then (with no internet and just some books) nothing felt “out of place” for me.davidraab.github.io
Im working on a script to test using a jump server to reach remote devices.
I'm able to connect to the jump server using Net::SSH::Expect, however, I'm not sure how to then ssh to a remote device (network element).
Is there a way to create that ssh to the remote device inside the jump server's connection?

First things first, I am a data engineer but have little experience in Perl. I've been able to make some easy updates to scripts in the past but this one is a bit tougher.
I have been asked to update a Perl cgi web app that someone wrote ages ago that is used to view and manipulate text files. Currently it is hosted on server (X) and manipulates the files on that same server. However, we have to have backups/mirrors of the data on a dev server and another prod sever (Y). I.e., if I push the button to move the file to a different folder, it should do that on all three servers instead of just X. I added code to do this, referencing the additional servers with their UNC names, but I just get an error "No such file or directory" (which is not true). Googling has suggested that there may be an issue with permissions, but I can bring up the Y and DEV servers from a windows file explorer using the same path so I don't think that is necessarily the issue.
Example: Here we are trying to copy the file with a letter appended a given number of times. It works fine on the X server, its when trying to make it also work on the Y and DEV servers I get an error.
our $DIR_X = "\\\\serverX\\folder\\subfolder" ; our $DIR_Y = "\\\\serverY\\folder\\subfolder"; our $DIR_DEV = "\\\\serverDEV\\folder\\subfolder"; . . . }elsif ($query->param('action') eq 'split' && $query->param('fileNum') ne "") { my $fileNum $query->param('fileNum'); my $fileX=$DIR_X . "\\" . $fileNum . ".txt"; my $fileY $DIR_Y . "\\" . $fileNum . ".txt"; my $fileDEV = $DIR_DEV . "\\" . $fileNum . ".txt"; my $splitNbr = $query->param('splitNbr'); my @letters1("a".. "z"); for (my $i = 0; $i < $splitNbr; $i++) { my $FileNew_X = $DIR_X . "\\" $fileNum. $letters[$i]=.txt"; my $FileNew_Y = $DIR_Y . "\\" $fileNum. $letters[$i]=.txt"; my $FileNew_DEV = $DIR_DEV . "\\" $fileNum. $letters[$i]=.txt"; copy($fileX, $FileNew_X) or die "WARNING: copy failed: $!\n"; ---->>>>>ERROR AT NEXT LINE copy($fileY, $FileNew_Y) or die "WARNING: copy failed: $!\n"; copy($fileDEV, $FileNew_DEV) or die "WARNING: copy failed: $!\n"; }
Any thoughts?

I stumbled upon this really nice page from Ruby, describing the language from the perspective of other common programming languages:
https://www.ruby-lang.org/en/documentation/ruby-from-other-languages/
The page is written in a friendly tone, inviting programmers familiar with other programming languages to Ruby. No programming language is being viewed as inferior, quite the contrary: all mentioned languages are praised and even defended from haters, for example:
- "Perl is awesome. Perl’s docs are awesome. The Perl community is … awesome. For those Perlers who long for elegant OO features built-in from the beginning, Ruby may be for you."
- "Happily, it turns out that Ruby and C have a healthy symbiotic relationship. And, of course, Ruby itself is written in C."
- "Java is mature. It’s tested. And it’s fast (contrary to what the anti-Java crowd may still claim)."
- "Python is another very nice general purpose programming language."
I believe Perl could greatly benefit from having a similar page. With its friendly philosophy and TMTOWTDI, it seems natural to invite programmers from other languages, with an approach of "Don't be afraid to keep programming the way you are used to, if it works in Perl, there are no limits enforced".
Since Perl is now not a common choice for new code or for learning, it makes a lot of sense to bring over people from other languages. Especially in an age where strict conventions seem to be praised, I can see Perl becoming a source of some fresh air.

I made this sample piece of code which I basically took from the docs, I only changed to infinite loop but I cannot understand why this would make any different between an infinite loop and iterating through an array for example? Anyway I am fighting this for several hours now trying different versions of my code and cannot find why am I getting "Cannot start another process while you are in the child process" all the time, any hints appreciated
output looks basically like this
Cannot start another process while you are in the child process at .... 16366 LOCK 16367 LOCK 16368 LOCK 16369 LOCK 16370 LOCK 16371 LOCK 16372 LOCK 16373 LOCK 16374 LOCK 16375 LOCK Cannot start another process while you are in the child process at ....

Prior releases of the 6.x line relied on Lexical::Types, which was a major performance pessimisation over the 5.x releases.
6.0.4 relies on a simple source filter instead, which restores performance levels back to expected levels.
