## Bundle
### Update bundler
`gem install bundler`
### Useful Bundle Commands
```
bundle outdated
bundle outdated --pre # pre-release gems
bundle install --path path to install gems
bundle install --system # removes path setting
bundle clean
bundle install --standalone # for a standalone bundle i.e. to copy to a server
```

## If dtrace is not working correctly when trying to build packages (like gems or npm packages)

`rvm install 2.3.8 -- --disable-dtrace`

### When using a clone of openssl
`rvm reinstall 2.3.8 --with-openssl-dir=/usr/local/opt/openssl`

## Set Default Ruby Version Using RVM
`rvm --default use 2.3.8`

## Other Issues

## If `rails generate` hangs
Might be caused by generated binstubs (https://github.com/rbenv/rbenv/wiki/Understanding-binstubs)
See: https://github.com/sstephenson/rbenv/wiki/Understanding-binstubs

To reset the binstubs, just delete your bin/ directory in rails and run:

### generates binstubs for ALL gems in the bundle
`bundle install --binstubs`

### generate binstubs for a SINGLE gem (recommended)
`bundle binstubs rake`

### rails 5
To reset the binstubs, just delete your bin/ directory in rails and run:
`rake app:update:bin`

# SideKiq specific
https://stackoverflow.com/questions/12683222/are-there-console-commands-to-look-at-whats-in-the-queue-and-to-clear-the-queue

## Require the SideKiq api
`require 'sidekiq/api'`

## get a handle to the default queue
`default_queue = Sidekiq::Queue.new `

## get a handle on a specific queue
`specific_queue = Sidekiq::Queue.new("specific")`

## How many jobs are in the default queue?
`default_queue.size`

## Deletes all Jobs in a Queue, by removing the queue.    
```
default_queue.clear
```
## Get the `stats` object
`stats = Sidekiq::Stats.new`

## Get the number of jobs that have been processed.
`stats.processed`

## Get the number of jobs that have failed.    
`stats.failed`

## Get the queues with name and number enqueued.
`stats.queues`

## Gets the number of jobs enqueued in all queues (does NOT include retries and scheduled jobs).
`stats.enqueued`

## See workers
`Sidekiq::Client.registered_workers`

## See queues
`Sidekiq::Client.registered_queues`

## See all jobs for one queue
`Sidekiq.redis { |r| r.lrange "queue:app_queue", 0, -1 }`

## See all jobs in all queues
```
Sidekiq::Client.registered_queues.each do |q|
  Sidekiq.redis { |r| r.lrange "queue:#{q}", 0, -1 }
end
```

## Remove a queue and all of its jobs
```
Sidekiq.redis do |r| 
  r.srem "queues", "app_queue"
  r.del  "queue:app_queue"
end
```

_Note:_ Unfortunately, removing a specific job is a little more difficult as you'd have to copy its exact value:

## Remove a specific job from a queue
`Sidekiq.redis { |r| r.lrem "queue:app_queue", -1, "the payload string stored in Redis" }`

## Delete all scheduled jobs
`Sidekiq::ScheduledSet.new.clear`

## Delete retry jobs
`Sidekiq::RetrySet.new.clear`

## Using `redis-cli`
```
$ redis-cli
> select 0 # (or whichever namespace Sidekiq is using)
> keys * # (just to get an idea of what you're working with)
> smembers queues
> lrange queues:app_queue 0 -1
> lrem queues:app_queue -1 "payload"
```
