Just found that the work around to always ensure the request is fully read by starting the breaking responder block with:
params.dup
as suggested in #21 works around this bug too.
here is the simplest reproduction i can find for problem (angelo 0.5.0, reel 0.6.2, ruby 2.3.1, ubuntu 14.04):
require 'angelo'
class PoorlyServer < Angelo::Base
post '/somepath' do
'some body'
end
end
PoorlyServer.run '127.0.0.1', 7077, {}, false
require 'net/http'
(1..10).each do
http = Net::HTTP.new '127.0.0.1', 7077
http.post '/somepath', 'somedata'
end
@damned thanks for your work on this, sorry I haven't responded until now. I'm working with the reel community to try to address this issue.
see my comment over on reel. interesting about params.dup
... let me investigate that a bit more.
so, this should work even without the .dup
, just by calling params, the request body is fully read.
all of the complexity behind Connection#request
is apparently in support of HTTP Pipelining, which according to wikipedia, isn't supported by current browsers.
@damned @kenichi IMO, the problem is connection#each_request will yield request once headers are parsed.
if you patch Reel::Request::Parser#current_request in you local reel like this reel/request/parser.rb
def current_request
until @currently_responding
readpartial
end
@currently_responding
end
your test will pass.

maybe i can send a fix from angelo side or reel side.
hi @respire thanks - i agree that is the problem, and i like the simplicity of the fix, but it causes reel specs to fail/hang on the pipelining stuff. i'm not opposed to taking that stuff out, but the larger reel org would need to consent. again, i don't think it's supported by modern browsers, and h2 makes h1.1 pipelining moot.
hi @kenichi - thanks for your reply! actually it's just an example patch to indicate the problem. it's not the final fix, and I agree that it's better to fix from angelo side. i'll send another PR from angelo side when I have time.
