em-redis incomplatibility

[karloscodes]

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]

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]

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]

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]

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

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

[karloscodes]

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

[bradgessler]

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]

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