Doesn't store anything to redis

[lellisga]

When I set a value in a rails console, it doesn't store it in the redis-cli, I looked for it and cannot find it, I try to run the monitor command but it doesn't seems to store anything.

[yaauie]

Please provide reproduction steps, including relevant environment variables, dependency versions, and code snippets.

@yaauie

1. I'm opening 2 rails consoles that are using the same redis instance
2. I run redis-cli and run the monitor command

rails console #1

r = Redis.new(:url => "redis://127.0.0.1:6379")
r.set("lellisga", "hi")
#=>"OK"

rails console #2

r = Redis.new(:url => "redis://127.0.0.1:6379")
me = r.get("lellisga")
#=> nil
# I was expecting this to return 'hi'

redis-cli monitor

redis 127.0.0.1:6379> MONITOR
OK
# nothing happens

[lellisga]

redis-cli 3.0.1 redis: stable 3.0.1 (bottled), HEAD

I can't seem to reproduce locally with redis-rb 3.0.1 (or the current 3.2.1) against redis-server 3.0.2 (which I have installed locally):

In one shell:

╭─{ yaauie@celeborn:~/src/yaauie/redis-rb (✔ v3.0.1/9e4c5a0) }
╰─● pry
[1] pry(main)> $: << File.expand_path('lib'); require 'redis' # uses the redis from my redis source working directory
=> true
[2] pry(main)> r = Redis.new(url: 'redis://127.0.0.1:6379')
=> #<Redis client v3.0.1 for redis://127.0.0.1:6379/0>
[3] pry(main)> r.set("lellisga", Time.now)
=> "OK"
[4] pry(main)> r.get("lellisga")
=> "2015-07-14 00:53:28 +0000"
[5] pry(main)> exit
[success]

In another shell:

╭─{ yaauie@celeborn:~/src/yaauie/redis-rb (✔ v3.0.1/9e4c5a0) }
╰─● pry
[1] pry(main)> $: << File.expand_path('lib'); require 'redis'
=> true
[2] pry(main)> r = Redis.new(url: 'redis://127.0.0.1:6379')
=> #<Redis client v3.0.1 for redis://127.0.0.1:6379/0>
[3] pry(main)> r.get("lellisga")
=> "2015-07-14 00:53:28 +0000"
[4] pry(main)> r.del("lellisga")
=> 1
[5] pry(main)> exit
[success]

and monitor:

╭─{ yaauie@celeborn:~/src/yaauie/redis-rb (✔ v3.0.1/9e4c5a0) }
╰─● redis-cli monitor
OK
1436835208.117667 [0 127.0.0.1:49386] "set" "lellisga" "2015-07-14 00:53:28 +0000"

If you get a value that you have just set in the same console, is a value returned?

[lellisga]

yeah

[lellisga]

1st Console

irb(main):002:0> r = Redis.new(url: 'redis://127.0.0.1:6379')
=> #<Redis client v3.1.0 for redis://127.0.0.1:6379/0>
irb(main):003:0> r.set("lellisga", Time.now)

=> "OK"

2nd Console

irb(main):002:0> r = Redis.new(url: 'redis://127.0.0.1:6379')
=> #<Redis client v3.1.0 for redis://127.0.0.1:6379/0>
irb(main):003:0> r.get("lellisga")
=> nil

[yaauie]

1. Run this in a single console:

r.set('test', Time.now)
#=> "ok"
r.get('test')
#=> "2015-07-14 01:31:17 +0000"

Does the value you set in one console persist for that console?

---

Are all three running on the same host? In a rails console, you can type:

`hostname -f`

---

Can you paste the contents of your Gemfile.lock (or link to a gist that contains it)? This should include the versions of all your gems, like rails, redis-rb, and anything else you're using that could be conflicting)

[lellisga]

Console 1

irb(main):008:0> `hostname -f`
=> "mac.local\n"
irb(main):009:0>  r = Redis.new(url: 'redis://127.0.0.1:6379')
=> #<Redis client v3.1.0 for redis://127.0.0.1:6379/0>
irb(main):010:0> r.set("test", "hey")
=> "OK"
irb(main):011:0> r.get("test")
=> "hey"
irb(main):012:0> 

console 2

irb(main):005:0> `hostname -f`
=> "mac.local\n"
irb(main):006:0> r = Redis.new(url: 'redis://127.0.0.1:6379')
=> #<Redis client v3.1.0 for redis://127.0.0.1:6379/0>
irb(main):007:0> r.get("test")
=> nil
irb(main):008:0>

[yaauie]

It looks like you're using the fakeredis gem, which overrides code from this redis driver to create a fake redis in process memory (which explains why the value is available in process and why your redis server never gets hit); remove it from your gemfile, or ensure it is not required.

[lellisga]

worked! thanks a lot @yaauie
