I have managed to start the firehose server with em-redis 0.2.1 and rainbows 4.5.0.

firehose server              
[2013-10-27 20:52:09.724 #30098] INFO : Starting 1.2.8 'Straight Stream', in development
[2013-10-27 20:52:10.574 #30098] INFO : listening on addr=0.0.0.0:7474 fd=7

[2013-10-27 20:52:10.788 #30137] INFO : EventMachine: epoll=true kqueue=false

However i can when i try:

curl "http://localhost:7474/hello"

I get curl: (52) Empty reply from server
I wonder if this is a em-redis or rainbows incompatibility problem

The issue is probably with rainbows. Try installing rainbows 4.4.3:

gem install rainbows -v 4.4.3

and see if that starts. We can at least isolate it to rainbows if that boots.

No luck with rainbows 4.4.3, i have also tried thin 1.3.1, 1.5.1, and
1.6.0 without any luck too.

What version of Redis server are you running?

$ redis-server -v
Redis server v=2.6.7 sha=00000000:0 malloc=libc bits=64

Make sure you're running at least 2.6.

Also try running

$ curl -X PUT -d "hi" "http://localhost:7474/hello"

against the server, then

$ curl "http://localhost:7474/hello"
{"message":"hi","last_sequence":1}

redis-server -v                                  
Redis server v=2.6.0 sha=00000000:0 malloc=jemalloc-3.0.0 bits=32

So i have 2.6.0, I have tried rubygems and github gems both of them with rainbows 4.4.3 and thin 1.3.1, 1.5.1, and 1.6.0.
I have checked and once the firehose server is running the 7474 port is open with telnet 7474.
Should i try with em-hiredis 0.2.0?

bradgessler commented

We're running * em-hiredis (0.2.1) in production without issue. I don't think that's the problem. What OS are you running? Mac?

karloscodes commented

I'm using Ubuntu 13.04 x86,
In order to fix or see what could be happening, what should i try? is there a way to make more verbose firehose server?

bradgessler commented

Oh crap, I just realized I haven't released 1.2.9 yet, which has em-hiredis bumpgrades. That explains why everything was working just fine and dandy for us in prod (we're synched up with HEAD on master) but you were having problems.

bradgessler commented

Gem cut http://rubygems.org/gems/firehose

Install that and bundle update everything, then see what happens.

karloscodes commented

Nothing, the same problem with 1.2.9 :-(
_curl: (52) Empty reply from server_,
What can i do?

bradgessler commented

Run LOG_LEVEL=debug firehose server and you'll get a more verbose output.

If that doesn't work lets isolate the crap of it via:

git clone git@github.com:polleverywhere/firehose.git
cd firehose
bundle
LOG_LEVEL=debug bundle exec bin/firehose server
curl "http://localhost:7474/hello" &
curl -X PUT -d "hi" "http://localhost:7474/hello"
bradgessler commented

Try updating the gem and rebundling. Issue https://github.com/polleverywhere/firehose/issues/29 may be causing these problems.
