Apparently i was not including the eos bucket in the new brigade.
It seems to work:
if ($b->is_eos) {
$this->my_function(\$f->ctx->{html},$f->r,$f->c);
#new bucket brigade to be filled with final modified bucket
my $nbb = APR::Brigade->new($f->c->pool,$f->c->bucket_alloc);
#new bucket, a unique and big bucket
my $nb = APR::Bucket->new($bb->bucket_alloc,$f->ctx->{html});
#insert the new bucket and the eos bucket
$nbb->insert_tail($nb);
$nbb->insert_tail($b);
#and pass the brigade, which is not going to be parsed by this handler
$rv = $f->next->pass_brigade($nbb);
last;
}
Before this function i was not worrying about the possibility to have broken
tags in this
handler. I say this because perhaps it is me, but i think to observe that now
the output
is appreciably slower.
What's your opinion about to create a big bucket? As i understand, buckets were
indeed
created to manage small pieces of info. I am doing the against. Is it very
inefficient? Do
you suggest me to work on a streaming-approach?
