redigo | Go client for the Redis database | Command Line Interface library

Wondering why redigo decided not to export the errorConn type, which would allow applications to have specific error handling for connection failures. As implemented, applications have to handle these as generic errors.

For example, our application generally doesn't care if a single PUT fails, but if the issue is a redis connection failure or redis pool being exhausted, moving on to the next PUT (especially if it requires opening a new connection) is a bad idea. We should stop and retry (with exponential backoff) until the connection comes back.

Code example where redigo returns a generic error if the connection pool is exhausted

I am using the code mentioned below to get output from Redis Publish-Subscribe. The message passed during the Redis publish a string (test-message).

However, the output that I get during subscribe stage is of type []uint8. Following is the output that I get when I run the below mentioned code [116 101 115 116 45 109 101 115 115 97 103 101] (instead of test-message which is the intended output.

This is caused by this line in the below mentioned code fmt.Println("Output: ", v.Data, reflect.TypeOf(v.Data)).

How can I get correct output that I desire in Subscribe in the aforesaid line (i.e. test-message)? I feel that I may need to convert from []uint8 to string to get the correct output.

My code is given below. I used this good answer as a reference for my code.

I am trying to use Redis PubSub in Go to be able pass / publish a message and retrieve it during subscription.

I have been able to set the publish and subscribe / PubSub parts of the code properly. Below is my code. The (string) message that I expect to retrieve during subscription is test message. But, the output of my code gives channel, kind and count and does not show the intended message (test message).

How can I get the intended message (test message) after Publish using Redis publish / subscribe in Go? I feel that I am close, but I may be missing a small thing here. I am very new to Redis. Thanks for your help.

Following is my code:

I'm using redigo to store and retrieve data in redigo. I have a struct that contains a type definition following time. I want to store the struct Data using HSET in Redis. I have a type definition to be able to use ScanStruct by adding a function RedisScan to my Timestamp type.

The problem is that Redis stores the Timestamp as ext, wall, loc following the time fields. You can't create a new Time object from these fields so that's fairly useless. What is the proper way to serialize a struct for redigo?

for the safety concern, we plan to change our redis passwd periodically(like every 4weeks). The question is how to change it without external downtime or just a very short period of time.

My plans are:

1. clear the passwd on redis server and restart.
2. seeing as there's no passwd required, clients can still reconnect to redis server even with obsolete passwd
3. clients reload new passwd from config center periodically, and soon after, all clients will have been updated to the new passwd.
4. change the redis server to new passwd and restart.
5. clients use new passwd to reconnect to redis server

But when I tried it(I'm using redigo), I got ERR Client sent AUTH, but no password is set on step 2. Seems like we can't connect to redis with extra passwd if it doesn't require passwd. But when I use redis-cli, it can! I want to know how redis-cli achieve this, and how can I do that with redigo?

I am using github.com/gomodule/redigo/redis library.

LPOP is working:

I am trying to add a record with a score into the sorted set if the record does not exist in the first place:

My dependencies in go.mod file is always updated and i don't know why. I have go.mod like this

I'm trying to implement a first-in, first-out task queue as described in Chapter 6.4.1 of the Redis e-book in Go. For testing purposes, I'm passing in a CommandExecutor interface to the 'worker' function like so:
