Perl Weekly=20

http://perlweekly.com/

You can read the newsletter on the web, if you prefer.
http://perlweekly.com/archive/506.html



Hi there

One topic that rarely talked about with reference to Perl is "Memory
Management". Could it be that, being a developer, you don't need to worry
about it? Possibly yes as Perl garbage collection is very efficient.
However you still have to take care of circular data structure manually. To
get to the bottom of the matter, one has to be aware of two things, "ref
count" and "weak ref". Can CPAN help me with it? Yes, there is a module
Devel::Peek ( https://metacpan.org/pod/Devel::Peek ) available on CPAN. You
can figure out about the "ref count". How about "weak ref" now? Well, again
CPAN is handy, you have Scalar::Util (
https://metacpan.org/pod/Scalar::Util ) readily available on CPAN, which
provides subroutine weaken() to create "weak ref". What is the point of
creating "weak ref"? Well, in Perl, the "weak ref" doesn't affect the "ref
count" and in a way helps you stop memory leak. I have yet to come across
simple working example to demonstrate this behaviour. However, you might
find the two recipes 11.15 (
https://docstore.mik.ua/orelly/perl4/cook/ch11_16.htm ) and 13.13 (
https://docstore.mik.ua/orelly/perl4/cook/ch13_14.htm ) from the good old
friend, "Perl Cookbook, second edition" very useful. There is another post,
The Trouble with Reference Counting (
https://www.perl.com/article/the-trouble-with-reference-counting ) by David
Farrell is also very interesting.

Talking about book, I would recommend you take a look at Perl New Features
( https://leanpub.com/perl_new_features ) by brian d foy. This book will
take you to a memorable journey from Perl v5.10 to v5.32.

To all readers from England, enjoy the Monday bank holiday and rest of
world start your week on a happy note starting with the weekly newsletter.

Could it be that, being a developer, you don't need to worry=<BR> about it? Possibly yes as Perl garbage collection is very efficient. Howev=<BR>er you still have to take care of circular data structure manually. To get =<BR>to the bottom of the matter, one has to be aware of two things, "ref count"=<BR> and "weak ref". Can CPAN help me with it? Yes, there is a module <a href=<BR>=3D"https://metacpan.org/pod/Devel::Peek">Devel::Peek</a> available on CPAN=<BR>. You can figure out about the "ref count". How about "weak ref" now? Well,=<BR> again CPAN is handy, you have <a href=3D"https://metacpan.org/pod/Scalar::=<BR>Util">Scalar::Util</a> readily available on CPAN, which provides subroutine=<BR> weaken() to create "weak ref". What is the point of creating "weak ref"? W=<BR>ell, in Perl, the "weak ref" doesn't affect the "ref count" and in a way he=<BR>lps you stop memory leak. I have yet to come across simple working example =<BR>to demonstrate this behaviour. However, you might find the two recipes <a h=<BR>ref=3D"https://docstore.mik.ua/orelly/perl4/cook/ch11_16.htm">11.15</a> and=<BR> <a href=3D"https://docstore.mik.ua/orelly/perl4/cook/ch13_14.htm">13.13</a=<BR>> from the good old friend, "Perl Cookbook, second edition" very useful.
