Threads / Refcounts

in reply to Re: Memory Leak Package
in thread Memory Leak Package

Good morning, my holy reverend

For my following little program I did no use threads

use strict; use warnings; use CProcess; # own class use B; CProcess->PrintProcessInfo("perl.exe");

# Output: Process-ID 12280: Memory 13716 KB (+13716 KB) - Peak 13716 KB - Threads 3 - Handles 115 (perl)

The only packages I use are:

use strict; use warnings; use Carp; use FileHandle; use Sys::Hostname; use Cwd; use Win32::Registry; use IO::Select; require Win32::Console; require Win32::Clipboard; require Win32::PerfLib; require Win32::OLE; require Tk::MainWindow; require 5.000; require Exporter;
perhaps one of them uses threads.

To count refcounts I use

require B; my $anon = []; my $otherref = $anon; my $refcount = B::svref_2object($anon)->REFCNT(); # => 2

which counts the referents of the referenced object (and not only of the variable itself like Devel::Peek)

    For my little program

    Is this the 400,000 line/100 package "small program"? :)

    I did not use threads

    I got the notion that you were using threads from your post:

    ID 7772: Memory 34200 KB ( 34200 KB) - Peak 34940 KB - Threads 3 - Han +dles 124 (perl) .......................................................^^^^^^^^^
    The only packages I use are: ... perhaps one of them uses threads.

    Hm. None of those use threads, (as in Perl Ithreads), that I am aware of.

    But Win32::OLE might well use -- or cause to be used -- kernel threads.

    But more interesting, is that none of those is XML::Simple as is the subject of How can I free the memory of a XML::Simple-Object?

[1nickt]: james28909 You lost me a bit when you said "show me evolution from intelligence to ignorance". I guess we would have to define the terms, but as I look around at my species and how we are destroying our habitat ...
[james28909]: seems like a person cant even have a belief without hurting someones feelings. i never said my way is the only way. i just said i have pretty good scientific evidence, and then asked for opposing side to present evidence
[james28909]: was downvoted and left without a reply. go figure
[holli]: but then you DO give a fuck
[1nickt]: I don;t think beliefs should be down-voted, just behaviours.
[james28909]: im not quite how to explain it any better nick. you evolved from ignorance to intelligence. not the other way. the universe evolves from gas coulds and debris into planets stars and galaxies ect. it doesnt happen any other way. hence it has ....
[james28909]: some kind of logic behind it
[james28909]: and that is also anothe rpoint i made, i think it has to do with perception of the world around you. most people think of evolution on a human scale. why could life evolve on this planet? because this planet evolved in this solar system. and so on.
[holli]: here's something for you to watch, James. I think you will like it
[erix]: for the record: I have not downvoted anyone on that subthread that was my fault
