Probably a stupid question but can't hurt to ask. In the docs they
consistently use @argv = qw(foo bar); Is there a reason for this, can
the args only be strings as semi-implied by somebody mentioning they
used JSON in another thread?
Or can I send $argv[0] = LARGE HASH ?
Thanks!

Environment variables have size limits - you should pass it as the args
reference because of that, and the fact that you're sending a pointer rather
than the whole data helps too, though the system is probably copying it
somewhere in there you shouldn't have to worry about it.
The point they're inferring in the examples is that the second element is a
list reference - not whether it's a referenced to a named list or not is
irrelevant.

Subject: Best way to pass arguments to an Apache2::SubProcess?
So my will has crumbled, mostly because I'm probably not very good at
the "resident in memory" part of mod_perl and I will be using
Apache2::SubProcess to fire off a sub-process.
There seems to be two easy ways to send data to my detached sub-process;
via an \...@args or via $r->subprocess_env->set.
I would like to pass large data structures which I will JSON encode and
I'm wondering which of the above would be best for that, if any, and
what the limitations are of either.
Also, I was wondering, in the docs for Apache2::SubProcess in the
section about properly detaching the sub-process it has in the example:
$r->spawn_proc_prog ('/path/to/detach_script.pl', $args);
Is there a reason $args is used rather than \...@args as outlined earlier
in the docs?
opt arg2: \...@argv ( ARRAY ref )
Or is it possible to create an $args->[0..10] and pass that?
Thanks!
Tosh
