I am having trouble that my script should change a shared variable based on a signal.
The signal is caught and the shared variable is changed, but the program does automatically stop.
See below some a small piece of code as an example.
I am using Perl 5.10.0 and CentOS 4.
use threads;
use threads::shared;
$SIG{'HUP'}='switchFlag';
$flag::shared;
my $thr=threads->new(\&printer);
$thr->detach();
sleep 10000;
print "I am here\n";
exit;
sub printer{
while(1) {
sleep 1;
print "Shared: $flag\n";
}
}
sub switchFlag{
$flag=!$flag;
print "signal caught";
$SIG{'HUP'}='switchFlag';
}
Update: Same behaviour with Perl 5.8 under Solaris 10...

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

are good places to start.
