04:23:05 GMT <waterdrop> Hi, I'm wondering if there's some standard way to handle race conditions in Redis (I'm using Redis from Python if that matters). I'm using a linked list in Redis as a queue, but I have one process that pushes items onto the queue and one process that pops items from the queue
04:24:01 GMT <waterdrop> So I'm worried about the case where process A reads the state of Redis, pushes an item onto the queue, and then writes its new version of the queue to Redis. And process B concurrently does the same (with the difference of popping an item off the queue), but then it overwrites the new version created by process A.
06:28:05 GMT <dudeji> Hi guys , can we open close connection at very high rate ?
06:28:27 GMT <dudeji> I had heard Tcp-connection close bug was open few months back , is it resolved ?
10:04:52 GMT <mickkelodeon> morning !
10:05:18 GMT <mickkelodeon> is it possible to use external libraries in a lua script that runs in redis?
10:10:56 GMT <badboy_> no
10:11:03 GMT <badboy_> only the ones included
10:11:07 GMT <badboy_> unless you patch your redis
10:11:31 GMT <badboy_> (which is not that hard, but you are on your own if you do: https://fnordig.de/2014/07/27/extending-redis-with-lua-packages/)
10:12:39 GMT <mickkelodeon> badboy_: which ones are included?
10:12:56 GMT <badboy_> http://redis.io/commands/eval#available-libraries
10:13:32 GMT <mickkelodeon> well, I can probably include the library in my code
10:13:52 GMT <mickkelodeon> badboy_: is there a limit in terms of code size ?
10:14:29 GMT <badboy_> limited by memory
10:15:08 GMT <badboy_> if it is a pure-lua lib, you can include it, sure
10:15:08 GMT <mickkelodeon> ok, so I can add it to my code then
10:15:16 GMT <badboy_> what library is it?
10:15:35 GMT <mickkelodeon> nothing yet, just wondering if that could be possible
10:21:41 GMT <badboy_> ah
10:28:43 GMT <mickkelodeon> thanks badboy_ , bye
13:17:56 GMT <freakyy> hi all. i have a question. im totally new to redis. i have redis set up in a docker. now, how do i secure it i mean, its accessible over the web, but ... it has no password user anything set?
13:19:28 GMT <minus> freakyy: simplest way is to not expose it to the internet
13:19:46 GMT <minus> by exposing it to 127.0.0.1 only
13:20:20 GMT <minus> like docker run -p 127.0.0.1:6379:6379 or so
13:22:52 GMT <freakyy> hm ok thanks ...
13:26:49 GMT <freakyy> minus: but then still local users on my server could access the database? they could remove stuff etc. i dont want that ...
13:26:56 GMT <minus> you can set a password too, but it's better to not put it on the internet at all
13:27:03 GMT <minus> yes
13:27:36 GMT <minus> if you don't run redis in a docker container you could do access control by binding it to a unix socket instead ofa tcp socket
13:27:59 GMT <minus> requirepass in the config sets the password
13:28:35 GMT <freakyy> hm that's really insecufre i might switch to mongodb ...
13:29:26 GMT <rob_> freakyy: ... its not insecure to bind it to a unix socket
13:29:44 GMT <rob_> how exactly do you think mongodb works? (hint: in exactly the same way as redis)
13:31:06 GMT <freakyy> rob_: mongodb uses users and passwords ;D
13:31:21 GMT <freakyy> thanks for all your help though :)
13:31:29 GMT <rob_> you dont understand security
13:31:36 GMT <rob_> so good luck with that
13:31:38 GMT <freakyy> thanks
13:31:56 GMT <minus> unix sockets provide the same level of protection as username/password for local applications
13:32:14 GMT <minus> in fact even more since there is no way of imposing some other user if you have the password
13:32:29 GMT <minus> though if you have access you have full control
14:23:56 GMT <marcv> Hello. I need to perform a given action whenever a key is eliminated, either because it auto-expires or because I make it expire manually. I set up a subscriber for expiration and it works fine, the event is handled when the key expires by itself, or when I call EXPIRE on it with a number of seconds greater than 0. However, if I "EXPIRE key 0" (to have it expire immediately), my subscriber isn't notified. Am I doing something wrong 
16:01:03 GMT <raj0098> How can I modify "bind" of a running server without restarting?
16:01:20 GMT <minus> probably not
16:01:49 GMT <minus> if you execute config get * and don't see a bind option in there it's a no
16:03:11 GMT <raj0098> no it's not there.. thanks for the tip! :)
18:46:34 GMT <nezZario> Hey guys .. Can someone help me out?  I'd like to setup AOF ... But I'm a little confused .. How does AOF + RDB work when both are enabled?
19:44:49 GMT <aarwine> I just want to make sure I'm reading this right. If I want HA in redis, my best bet is to create a replica off my master, then use a sentinel-cluster to handle the auto failover of the writes? My app points at the sentinel cluster instead of the redis master?
19:48:21 GMT <aarwine> Ok, the app discovers teh master IP from the sentinel instances then confirms it via role, but I'm still curious about the intial setup of things
19:48:27 GMT <bashusr> hi all, I am doing something similar to caching comments for a post; I can either store all the comments in a single data post and filter out results or I can store an index record and query for each comment stored in redis. Is it worth optimizing for fewer queries to redis and a larger dataset or does it not matter?
19:48:32 GMT <aarwine> stardard slaveofs I guess
19:48:33 GMT <aarwine> ?
19:53:36 GMT <nezZario> What i'm Sincerely confused about if anyone can answer..
19:55:38 GMT <nezZario> https://github.com/antirez/redis/pull/2574 --> this says now it will "migrate" RDB to AOF when you start the server with AOF disabled (and none exists)?  So it will read my RDB and generate a linear copy of it in AOF?  I am just really concerned because if you look at #2574 .. that closes #873 and I am the guy saying he lost 2.1GB of data in 2014 on #873 --
19:55:38 GMT <nezZario> So this subject is kind of close to heart.
