Hi Michael,
@param is only intented to be used to pass parameters to Execute. Setting it
directly might work or might not…
If you want to share data inside a request use
$epreq -> {test} = 1 ;
The hash of $epreq is not used by Embperl itself, so you are free to use it and
it exists exactly for the live time of one Apache request

My problem is slightly different - though possibly a manifestation of the same
thing. I find that param isn't cleaned up between requests.
I have two epl files:
set.epl:
[- $param[0]->{'test'} = 1 -]
get.epl
[+ Dumper(@param) +]
I find that the data from set.epl turns up when I make a subsequent request for
get.epl (in practice it's a bit more random than that if one is running
multiple processes, so I make a few requests for set.epl and then a few for
get.epl)
This only seems to be relevant if I reference param in the epl file I am
calling directly. If I reference it in epl files which are loaded in by
Execute, then they do appear to get cleaned up.

Note that, under Apache, the cleanup code happens at the end of each request -
each of which could have dozens of Execute calls, between which it is very
definitely NOT called.
I have not used Embperl much from within server scripts, but in my limited use
there, I've never seen the cleanup code fire. I suspect each script is
considered 'a request' for the purposes of the cleanup code (well, as far as
docs are concerned. I don't know if the code actually fires on END.)

Hi.
We're seeing an odd bug where @param seems to be shared between Execute
calls in the same process. The following code is a test case for this:
#!/usr/bin/perl -w
use strict;
use Embperl;
my $output1;
my $input = '[- $param[0]->{hello} = 42; -]';
Embperl::Execute({
inputfile => "blah",
input => \$input,
output => \$output1,
});
my $output2;
my $input2 = '[- use Data::Dumper; print Dumper(\...@param); -]';
Embperl::Execute({
inputfile => "blah",
input => \$input2,
output => \$output2
});
Which on my machine outputs:
$VAR1 = [
{
'hello' => 42
}
];
Surely this shouldn't happen?
