07:27:33 GMT <aeo1ack> Guys check out Zsh plugin that binds redis keys to shell variables, it's a milestone step from redis-cli: https://github.com/zdharma/zredis
08:24:35 GMT <kaos01> whats the ideal number of hosts for redis ?
08:28:40 GMT <badboy_> 1
08:35:03 GMT <kaos01> done :)
08:35:08 GMT <kaos01> 3 im guesing
08:35:44 GMT <badboy_> There's no right answer for that. It highly depends on your needs and requirements
08:35:50 GMT <kaos01> what the recomended way to configure HA ?
08:36:17 GMT <kaos01> sentinel ? or do people place nodes behing a load balancer like haproxy. f5 ?
08:37:11 GMT <badboy_> Sentinel is the in-built solution for HA and automatic failover, indeed
08:37:20 GMT <badboy_> but it requires a smarter client lib
08:37:24 GMT <kaos01> yeah
08:37:48 GMT <kaos01> so clients need to be specified not only master but slaves ?
08:38:11 GMT <kaos01> or client determines nodes via sentinel ...
08:38:17 GMT <kaos01> ?
08:41:20 GMT <badboy_> clients determine nodes by asking sentinels
08:42:15 GMT <minus> aeo1ack: thanks, but i'd rather use python then.
08:43:46 GMT <aeo1ack> minus: yeah heard about this, that people use python to fully manipulate data without building command strings for redis-cli. Could you provide how to bind list with python, and remove 1st element?
08:44:36 GMT <kaos01> so does the sentinel way suffice or are other ha options prefered ?
08:44:43 GMT <minus> meh to binding, but there is a lib for that, never used it though
08:45:12 GMT <minus> aeo1ack: https://walrus.readthedocs.io/en/latest/containers.html#lists
08:47:00 GMT <aeo1ack> still it might be fun, for administrator, to bind string variable "visitors" to redis key "visitors", and invoke "echo $visitors" from time to time, instead of browsing history for redis-cli command
08:51:59 GMT <aeo1ack> "unset visitors" will remove the key "visitors", wonder if people will slip, to invoke unset instead of "zruntie visitors"
08:52:56 GMT <badboy_> if that is a useful metric, they should build themselves a dashboard exporting this information
08:53:14 GMT <badboy_> but nonetheless, I appreciate your contribution, even if I don't see a use case for myself
08:55:04 GMT <aeo1ack> thanks, I hope someone likes it, although Zsh might be an obstacle, also basic certanity about zsh types is needed, e.g. to do list[10,-20]=() to remove part of keys, it is simple but the certanity of Zsh knowledge is IMO needed to use that
08:56:26 GMT <aeo1ack> The use case I see is reqular daily work of a developer, if he has dev experimental redis database, and needs to fill it with fancy or large in number data many times a day
18:38:56 GMT <posi> Hey everyone i'm doing a bunch of lua scripts in redis and i realized I need access to ffi, but I can't seem to require ffi. What gives? Am I screwed?
18:40:15 GMT <minus> posi: FFI in Redis Lua scripts? no chance. Redis 4 will have loadable modules, those might fit your needs
18:42:27 GMT <posi> ahh nice
18:42:34 GMT <posi> kk
18:44:52 GMT <posi> minus: I want to expose murmur3 to the script instead of sha
18:44:56 GMT <posi> minus: any other routes?
18:45:40 GMT <minus> implement it in Lua
18:46:11 GMT <minus> no other ways that i know of, besides modifying redis itself
18:46:16 GMT <posi> it's very difficult without being able to pull in packages like bit or struct
18:46:28 GMT <posi> minus: I am actually ok with building a custom redis
18:47:23 GMT <minus> a module would be the preferrable solution, but Redis 4 hasn't been released yet, so you'd need to run unstable
18:49:11 GMT <posi> cool
18:49:13 GMT <posi> what's the timing there?
18:50:23 GMT <minus> oh, an RC was release 181 days ago

19:15:19 GMT <t0th_-_> hi
19:15:25 GMT <t0th_-_> how i cal solve this error: MISCONF Redis is configured to save RDB snapshots, but is currently not able to persist on disk. Commands that may modify the data set are disabled. Please check Redis logs for details about the error. ?
19:19:48 GMT <psprint> Can magit "revert" single lines, i.e. I look at unstaged diff, select some lines, want to reset them to current HEAD
19:28:50 GMT <t0th_-_> how i cal solve this error: MISCONF Redis is configured to save RDB snapshots, but is currently not able to persist on disk. Commands that may modify the data set are disabled. Please check Redis logs for details about the error. ?
19:31:58 GMT <minus> t0th_-_: check `CONFIG GET dir` for where it tries to save to and make sure that's the correct, writable location
19:32:35 GMT <t0th_-_> -rw-r--r--  1 redis redis  71M Jun  1 16:31 dump.rdb
19:32:40 GMT <t0th_-_> how i can do it writable ?
19:34:26 GMT <minus> that should be writable by the redis user. if redis runs as that and the is the actually set dir (the config file does not necessarily reflect the current value, CONFIG GET does) and the disk is not full, it should work
19:37:22 GMT <t0th_-_> but it is writable to redis file
19:38:08 GMT <t0th_-_> redis user
19:42:21 GMT <minus> is that the actual location `CONFIG GET dir` returns?
19:42:32 GMT <minus> if you haven't checked, check it now
20:03:38 GMT <t0th_-_> how i can see if it worked?
20:04:17 GMT <minus> redis-cli should return the value then
20:06:12 GMT <t0th_-_> yes
20:06:17 GMT <t0th_-_> i setted the permission
20:06:23 GMT <t0th_-_> in the directory and file
20:06:35 GMT <t0th_-_> in directory returned by CONFIG GET dir
20:06:41 GMT <t0th_-_> 755 to dir and 644 do file
20:07:05 GMT <minus> /var/lib/redis?
20:07:18 GMT <t0th_-_> i see RDB: 53 MB of memory used by copy-on-write and Background saving terminated with success. It is work?
20:07:22 GMT <minus> it doesn't need to be world readable, but that doesn't prevent it from saving
20:07:32 GMT <minus> yes, that looks okay
20:07:38 GMT <t0th_-_> thanks, minus
20:07:57 GMT <t0th_-_> ./var/lib/redis yes this directory
