Woot! Its zeromq stuff. My new test app:
#!/usr/bin/perl
use common::sense;
use ZeroMQ ':all';
use Data::Dumper;
my $ctx = ZeroMQ::Context->new();
my $sock = $ctx->socket(ZMQ_PULL);
$sock->setsockopt(ZMQ_HWM, 500);
$sock->bind('tcp://*:5558');
$SIG{HUP} = sub {
print "got hup\n";
};
while (1)
{
my $msg = $sock->recv();
print "got message\n";
print Dumper(\$msg);
}
after I sighup it, I get:
got hup
got message
$VAR1 = \undef;
In real code, I call $msg->data() next which when $msg is undef I can see that killing the script.
Its kinda weird that SIGHUP makes $sock->recv() return, but at least I can code around that.
thanks again,
-Andy

Are you posting in the right place? Check out Where do I post X? to know for sure.

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).

Want more info? How to link
or How to display code and escape characters
are good places to start.
