The underlying problem is bad unmarshalling of the Ferret::Document that
gets sent to the DRb server.
In ferret_server.rb:
rescue NoMethodError
@logger.debug "no luck, trying to call class method instead"
Using rescue NoMethodError => e and then include e.message in the debug
output, reveals:
undefined method `to_doc' for #<DRb::DRbUnknown:0x2a9808f3f0>
I'm pretty blank as to why Ferret::Document does not get properly
unmarshalled on the initial request. If I change the add method to
attempt a DRb reload in local_index.rb (line ~139):
def add(record)
if record.is_a?(DRb::DRbUnknown)
record = record.reload
logger.warn("Reloaded DRb::DRbUnknown to #{record.class.name}")
end
record = record.to_doc unless Hash === record || Ferret::Document ===
record
ferret_index << record
end
Then I do indeed get a Document instance back, ie. I have a work around.
But why does this work around work? Does the unmarshalling process occur
before the relevant classes get loaded in the initial request?
I'll patch up my local AAF to use this work around, but as it does not
solve the actual root problem, I guess it's not interesting as a patch
submission.
