Hi all,

I would like to know the consequence in using alarm and die in a perl-handler. For example consider this http://wiki.codemongers.com/NginxEmbeddedPerlImageResize

The blocking code is the following

$image= new Image::Magick; $image->Read($real_file_path); $image->Scale($dimensions); $image->Write($dest_file);

Sometimes this code can hold all resources and normal requests cannot be served.

So if I follow the example from mod_perl and die in 2 seconds, what will be the consequence to the current requests?

my $timeout = 2; # seconds eval { local $SIG{ALRM} = sub { die "Sorry, timed out. Please try again\n" }; alarm $timeout; # the operation listed above alarm 0; };

die $@ if $@;
