Thanks Philippe,
It's now no longer failing, however the input filter is not returning any
data and I get the following error in error_log:
-e: Deep recursion on subroutine "ZCRM::OFilter::input" at
/opt/code/CRM/OFilter.pm line 42.
Here's the subroutine:
sub input {
my $f = shift;
my $r = $f->r;
my $bb = APR::Brigade->new( $r->pool, $r->connection->bucket_alloc );
my $data = '';
my $seen_eos = 0;
do {
$r->input_filters->get_brigade( $bb, Apache2::Const::MODE_READBYTES,
APR::Const::BLOCK_READ, IOBUFSIZE );
for ( my $b = $bb->first ; $b ; $b = $bb->next($b) ) {
if ( $b->is_eos ) {
$seen_eos++;
last;
}
if ( $b->read( my $buf ) ) {
$data .= $buf;
}
$b->remove; # optimization to reuse memory
}
} while ( !$seen_eos );
$bb->destroy;
return $data;
}
