# GitLab Rails Console Cheat Sheet

This is the GitLab Support Team's collection of information regarding the GitLab Rails
console, for use while troubleshooting. It is listed here for transparency,
and it may be useful for users with experience with these tools. If you are currently
having an issue with GitLab, it is highly recommended that you check your
[support options](https://about.gitlab.com/support/) first, before attempting to use
this information.

CAUTION: **Caution:**
Please note that some of these scripts could be damaging if not run correctly,
or under the right conditions. We highly recommend running them under the
guidance of a Support Engineer, or running them in a test environment with a
backup of the instance ready to be restored, just in case.

CAUTION: **Caution:**
Please also note that as GitLab changes, changes to the code are inevitable,
and so some scripts may not work as they once used to. These are not kept
up-to-date as these scripts/commands were added as they were found/needed. As
mentioned above, we recommend running these scripts under the supervision of a
Support Engineer, who can also verify that they will continue to work as they
should and, if needed, update the script for the latest version of GitLab.

## Find specific methods for an object

```ruby
Array.methods.select { |m| m.to_s.include? "sing" }
Array.methods.grep(/sing/)
```

## Find method source

Works for [non-instrumented methods](../../development/instrumentation.md#checking-instrumented-methods):

```ruby
instance_of_object.method(:foo).source_location

# Example for when we would call project.private?
project.method(:private?).source_location
```

## Query the database using an ActiveRecord Model

```ruby
m = Model.where('attribute like ?', 'ex%')

# for example to query the projects
projects = Project.where('path like ?', 'Oumua%')
```

## View all keys in cache

```ruby
Rails.cache.instance_variable_get(:@data).keys
```

## Profile a page

```ruby
# Before 11.6.0
logger = Logger.new(STDOUT)
admin_token = User.find_by_username('ADMIN_USERNAME').personal_access_tokens.first.token
app.get("URL/?private_token=#{admin_token}")

# From 11.6.0
admin = User.find_by_username('ADMIN_USERNAME')
url = "/url/goes/here"
Gitlab::Profiler.with_user(admin) { app.get(url) }
```

## Using the GitLab profiler inside console (used as of 10.5)

```ruby
logger = Logger.new(STDOUT)
admin = User.find_by_username('ADMIN_USERNAME')
Gitlab::Profiler.profile('URL', logger: logger, user: admin)
```

## Time an operation

```ruby
# A single operation
Benchmark.measure { <operation> }

# A breakdown of multiple operations
Benchmark.bm do |x|
  x.report(:label1) { <operation_1> }
  x.report(:label2) { <operation_2> }
end
```

## Feature flags

### Show all feature flags that are enabled

```ruby
# Regular output
Feature.all

# Nice output
Feature.all.map {|f| [f.name, f.state]}
```

## Command Line

### Check the GitLab version fast

```shell
grep -m 1 gitlab /opt/gitlab/version-manifest.txt
```

### Debugging SSH

```shell
GIT_SSH_COMMAND="ssh -vvv" git clone <repository>
```

### Debugging over HTTPS

```shell
GIT_CURL_VERBOSE=1 GIT_TRACE=1 git clone <repository>
```

## Projects

### Clear a project's cache

```ruby
ProjectCacheWorker.perform_async(project.id)
```

### Expire the .exists? cache

```ruby
project.repository.expire_exists_cache
```

### Make all projects private

```ruby
Project.update_all(visibility_level: 0)
```

### Find & remove projects that are pending deletion

```ruby
#
# This section will list all the projects which are pending deletion
#
projects = Project.where(pending_delete: true)
projects.each do |p|
  puts "Project ID: #{p.id}"
  puts "Project name: #{p.name}"
  puts "Repository path: #{p.repository.full_path}"
end

#
# Assign a user (the root user will do)
#
user = User.find_by_username('root')

#
# For each project listed repeat these two commands
#

# Find the project, update the xxx-changeme values from above
project = Project.find_by_full_path('group-changeme/project-changeme')

# Immediately delete the project
::Projects::DestroyService.new(project, user, {}).execute
```

Next, run `sudo gitlab-rake gitlab:cleanup:repos` on the command line to finish.

### Destroy a project

```ruby
project = Project.find_by_full_path('')
user = User.find_by_username('')
ProjectDestroyWorker.perform_async(project.id, user.id, {})
# or ProjectDestroyWorker.new.perform(project.id, user.id, {})
# or Projects::DestroyService.new(project, user).execute
```

### Remove fork relationship manually

```ruby
p = Project.find_by_full_path('')
u = User.find_by_username('')
::Projects::UnlinkForkService.new(p, u).execute
```

### Make a project read-only (can only be done in the console)

```ruby
# Make a project read-only
project.repository_read_only = true; project.save

# OR
project.update!(repository_read_only: true)
```

### Transfer project from one namespace to another

```ruby
 p= Project.find_by_full_path('')

 # To set the owner of the project
 current_user= p.creator

# Namespace where you want this to be moved.
namespace = Namespace.find_by_full_path("")

::Projects::TransferService.new(p, current_user).execute(namespace)
```

### For Removing webhooks that is getting timeout due to large webhook logs

```ruby
# ID will be the webhook_id
hook=WebHook.find(ID)

WebHooks::DestroyService.new(current_user).execute(hook)

#In case the service gets timeout consider removing webhook_logs
hook.web_hook_logs.limit(BATCH_SIZE).delete_all
```

### Bulk update service integration password for _all_ projects

For example, change the Jira user's password for all projects that have the Jira
integration active:

```ruby
p = Project.find_by_sql("SELECT p.id FROM projects p LEFT JOIN services s ON p.id = s.project_id WHERE s.type = 'JiraService' AND s.active = true")

p.each do |project|
  project.jira_service.update_attribute(:password, '<your-new-password>')
end
```

### Bulk update to disable the Slack Notification service

To disable notifications for all projects that have Slack service enabled, do:

```ruby
# Grab all projects that have the Slack notifications enabled
p = Project.find_by_sql("SELECT p.id FROM projects p LEFT JOIN services s ON p.id = s.project_id WHERE s.type = 'SlackService' AND s.active = true")

# Disable the service on each of the projects that were found.
p.each do |project|
  project.slack_service.update_attribute(:active, false)
end
```

### Incorrect repository statistics shown in the GUI

After [reducing a repository size with third-party tools](../../user/project/repository/reducing_the_repo_size_using_git.md)
the displayed size may still show old sizes or commit numbers. To force an update, do:

```ruby
p = Project.find_by_full_path('<namespace>/<project>')
pp p.statistics
p.statistics.refresh!
pp p.statistics  # compare with earlier values
```

## Wikis

### Recreate

A Projects Wiki can be recreated by

NOTE: **Note:**
This is a destructive operation, the Wiki will be empty.

```ruby
p = Project.find_by_full_path('<username-or-group>/<project-name>')  ### enter your projects path

GitlabShellWorker.perform_in(0, :remove_repository, p.repository_storage, p.wiki.disk_path)  ### deletes the wiki project from the filesystem

p.create_wiki  ### creates the wiki project on the filesystem
```

## Issue boards

### In case of issue boards not loading properly and it's getting time out. We need to call the Issue Rebalancing service to fix this

```ruby
p=Project.find_by_full_path('PROJECT PATH')

IssueRebalancingService.new(p.issues.take).execute
```

## Imports / Exports

```ruby
# Find the project and get the error
p = Project.find_by_full_path('<username-or-group>/<project-name>')

p.import_error

# To finish the import on GitLab running version before 11.6
p.import_finish

# To finish the import on GitLab running version 11.6 or after
p.import_state.mark_as_failed("Failed manually through console.")
```

### Rename imported repository

In a specific situation, an imported repository needed to be renamed. The Support
Team was informed of a backup restore that failed on a single repository, which created
the project with an empty repository. The project was successfully restored to a development
instance, then exported, and imported into a new project under a different name.

The Support Team was able to transfer the incorrectly named imported project into the
correctly named empty project using the steps below.

Move the new repository to the empty repository:

```shell
mv /var/opt/gitlab/git-data/repositories/<group>/<new-project> /var/opt/gitlab/git-data/repositories/<group>/<empty-project>
```

Make sure the permissions are correct:

```shell
chown -R git:git <path-to-directory>.git
```

Clear the cache:

```shell
sudo gitlab-rake cache:clear
```

## Repository

### Search sequence of pushes to a repository

If it seems that a commit has gone "missing", search the sequence of pushes to a repository.
[This StackOverflow article](https://stackoverflow.com/questions/13468027/the-mystery-of-the-missing-commit-across-merges)
describes how you can end up in this state without a force push.

If you look at the output from the sample code below for the target branch, you will
see a discontinuity in the from/to commits as you step through the output. Each new
push should be "from" the "to" SHA of the previous push. When this discontinuity happens,
you will see two pushes with the same "from" SHA:

```ruby
p = Project.find_with_namespace('u/p')
p.events.pushed_action.last(100).each do |e|
  printf "%-20.20s %8s...%8s (%s)\n", e.data[:ref], e.data[:before], e.data[:after], e.author.try(:username)
end
```

GitLab 9.5 and above:

```ruby
p = Project.find_by_full_path('u/p')
p.events.pushed_action.last(100).each do |e|
  printf "%-20.20s %8s...%8s (%s)\n", e.push_event_payload[:ref], e.push_event_payload[:commit_from], e.push_event_payload[:commit_to], e.author.try(:username)
end
```

## Mirrors

### Find mirrors with "bad decrypt" errors

This content has been converted to a Rake task, see the [Doctor Rake tasks docs](../raketasks/doctor.md).

### Transfer mirror users and tokens to a single service account

Use case: If you have multiple users using their own GitHub credentials to set up
repository mirroring, mirroring breaks when people leave the company. Use this
script to migrate disparate mirroring users and tokens into a single service account:

```ruby
svc_user = User.find_by(username: 'ourServiceUser')
token = 'githubAccessToken'

Project.where(mirror: true).each do |project|
  import_url = project.import_url

  # The url we want is https://token@project/path.git
  repo_url = if import_url.include?('@')
               # Case 1: The url is something like https://23423432@project/path.git
               import_url.split('@').last
             elsif import_url.include?('//')
               # Case 2: The url is something like https://project/path.git
               import_url.split('//').last
             end

  next unless repo_url

  final_url = "https://#{token}@#{repo_url}"

  project.mirror_user = svc_user
  project.import_url = final_url
  project.username_only_import_url = final_url
  project.save
end
```

## Users

### Skip reconfirmation

```ruby
user = User.find_by_username ''
user.skip_reconfirmation!
```

### Active users & Historical users

```ruby
# Active users on the instance, now
User.active.count

# Users taking a seat on the instance
License.current.current_active_users_count

# The historical max on the instance as of the past year
::HistoricalData.max_historical_user_count
```

```shell
# Using curl and jq (up to a max 100, see pagination docs https://docs.gitlab.com/ee/api/#pagination
curl --silent --header "Private-Token: ********************" "https://gitlab.example.com/api/v4/users?per_page=100&active" | jq --compact-output '.[] | [.id,.name,.username]'
```

### Block or Delete Users that have no projects or groups

```ruby
users = User.where('id NOT IN (select distinct(user_id) from project_authorizations)')

# How many users will be removed?
users.count

# If that count looks sane:

# You can either block the users:
users.each { |user| user.block! }

# Or you can delete them:
  # need 'current user' (your user) for auditing purposes
current_user = User.find_by(username: '<your username>')

users.each do |user|
  DeleteUserWorker.perform_async(current_user.id, user.id)
end
```

### Block Users that have no recent activity

```ruby
days_inactive = 60
inactive_users = User.active.where("last_activity_on <= ?", days_inactive.days.ago)

inactive_users.each do |user|
    puts "user '#{user.username}': #{user.last_activity_on}"
    user.block!
end
```

### Find Max permissions for project/group

```ruby
user = User.find_by_username 'username'
project = Project.find_by_full_path 'group/project'
user.max_member_access_for_project project.id
```

```ruby
user = User.find_by_username 'username'
group = Group.find_by_full_path 'group'
user.max_member_access_for_group group.id
```

## Groups

### Count unique users in a group and sub-groups

```ruby
group = Group.find_by_path_or_name("groupname")
members = []
for member in group.members_with_descendants
   members.push(member.user_name)
end

members.uniq.length
```

```ruby
group = Group.find_by_path_or_name("groupname")

# Count users from subgroup and up (inherited)
group.members_with_parents.count

# Count users from the parent group and down (specific grants)
parent.members_with_descendants.count
```

### Delete a group

```ruby
GroupDestroyWorker.perform_async(group_id, user_id)
```

### Modify group project creation

```ruby
# Project creation levels: 0 - No one, 1 - Maintainers, 2 - Developers + Maintainers
group = Group.find_by_path_or_name('group-name')
group.project_creation_level=0
```

## SCIM

### Fixing bad SCIM identities

```ruby
def delete_bad_scim(email, group_path)
    output = ""
    u = User.find_by_email(email)
    uid = u.id
    g = Group.find_by_full_path(group_path)
    saml_prov_id = SamlProvider.find_by(group_id: g.id).id
    saml = Identity.where(user_id: uid, saml_provider_id: saml_prov_id)
    scim = ScimIdentity.where(user_id: uid , group_id: g.id)
    if saml[0]
      saml_eid = saml[0].extern_uid
      output +=  "%s," % [email]
      output +=  "SAML: %s," % [saml_eid]
      if scim[0]
        scim_eid = scim[0].extern_uid
        output += "SCIM: %s" % [scim_eid]
        if saml_eid == scim_eid
          output += " Identities matched, not deleted \n"
        else
          scim[0].destroy
          output += " Deleted \n"
        end
      else
        output = "ERROR No SCIM identify found for: [%s]\n" % [email]
        puts output
        return 1
      end
    else
      output = "ERROR No SAML identify found for: [%s]\n" % [email]
      puts output
      return 1
    end
      puts output
    return 0
end

# In case of multiple emails
emails = [email1, email2]

emails.each do |e|
  delete_bad_scim(e,'GROUPPATH')
end
```

## Routes

### Remove redirecting routes

See <https://gitlab.com/gitlab-org/gitlab-foss/-/issues/41758#note_54828133>.

```ruby
path = 'foo'
conflicting_permanent_redirects = RedirectRoute.matching_path_and_descendants(path)

# Check that conflicting_permanent_redirects is as expected
conflicting_permanent_redirects.destroy_all
```

## Merge Requests

### Close a merge request properly (if merged but still marked as open)

```ruby
p = Project.find_by_full_path('<full/path/to/project>')
m = p.merge_requests.find_by(iid: <iid>)
u = User.find_by_username('')
MergeRequests::PostMergeService.new(p, u).execute(m)
```

### Delete a merge request

```ruby
u = User.find_by_username('<username>')
p = Project.find_by_full_path('<group>/<project>')
m = p.merge_requests.find_by(iid: <IID>)
Issuable::DestroyService.new(m.project, u).execute(m)
```

### Rebase manually

```ruby
p = Project.find_by_full_path('')
m = project.merge_requests.find_by(iid: )
u = User.find_by_username('')
MergeRequests::RebaseService.new(m.target_project, u).execute(m)
```

## CI

### Cancel stuck pending pipelines

For more information, see the [confidential issue](../../user/project/issues/confidential_issues.md)
`https://gitlab.com/gitlab-com/support-forum/issues/2449#note_41929707`.

```ruby
Ci::Pipeline.where(project_id: p.id).where(status: 'pending').count
Ci::Pipeline.where(project_id: p.id).where(status: 'pending').each {|p| p.cancel if p.stuck?}
Ci::Pipeline.where(project_id: p.id).where(status: 'pending').count
```

### Remove artifacts more than a week old

This section has been moved to the [job artifacts troubleshooting documentation](../job_artifacts.md#delete-job-artifacts-from-jobs-completed-before-a-specific-date).

### Find reason failure (for when build trace is empty) (Introduced in 10.3.0)

See <https://gitlab.com/gitlab-org/gitlab-foss/-/issues/41111>.

```ruby
build = Ci::Build.find(78420)

build.failure_reason

build.dependencies.each do |d| { puts "status: #{d.status}, finished at: #{d.finished_at},
  completed: #{d.complete?}, artifacts_expired: #{d.artifacts_expired?}, erased: #{d.erased?}" }
```

### Try CI service

```ruby
p = Project.find_by_full_path('')
m = project.merge_requests.find_by(iid: )
m.project.try(:ci_service)
```

### Validate the `.gitlab-ci.yml`

```ruby
project = Project.find_by_full_path 'group/project'
content = project.repository.gitlab_ci_yml_for(project.repository.root_ref_sha)
Gitlab::Ci::YamlProcessor.validation_message(content,  user: User.first)
```

### Disable AutoDevOps on Existing Projects

```ruby
Project.all.each do |p|
  p.auto_devops_attributes={"enabled"=>"0"}
  p.save
end
```

### Obtain runners registration token

```ruby
Gitlab::CurrentSettings.current_application_settings.runners_registration_token
```

## License

### See current license information

```ruby
# License information (name, company, email address)
License.current.licensee

# Plan:
License.current.plan

# Uploaded:
License.current.created_at

# Started:
License.current.starts_at

# Expires at:
License.current.expires_at

# Is this a trial license?
License.current.trial?
```

### Check if a project feature is available on the instance

Features listed in <https://gitlab.com/gitlab-org/gitlab/blob/master/ee/app/models/license.rb>.

```ruby
License.current.feature_available?(:jira_dev_panel_integration)
```

### Check if a project feature is available in a project

Features listed in [`license.rb`](https://gitlab.com/gitlab-org/gitlab/blob/master/ee/app/models/license.rb).

```ruby
p = Project.find_by_full_path('<group>/<project>')
p.feature_available?(:jira_dev_panel_integration)
```

### Add a license through the console

```ruby
key = "<key>"
license = License.new(data: key)
license.save
License.current # check to make sure it applied
```

## Unicorn

From [Zendesk ticket #91083](https://gitlab.zendesk.com/agent/tickets/91083) (internal)

### Poll Unicorn requests by seconds

```ruby
require 'rubygems'
require 'unicorn'

# Usage for this program
def usage
  puts "ruby unicorn_status.rb <path to unix socket> <poll interval in seconds>"
  puts "Polls the given Unix socket every interval in seconds. Will not allow you to drop below 3 second poll intervals."
  puts "Example: /opt/gitlab/embedded/bin/ruby poll_unicorn.rb /var/opt/gitlab/gitlab-rails/sockets/gitlab.socket 10"
end

# Look for required args. Throw usage and exit if they don't exist.
if ARGV.count < 2
  usage
  exit 1
end

# Get the socket and threshold values.
socket = ARGV[0]
threshold = (ARGV[1]).to_i

# Check threshold - is it less than 3? If so, set to 3 seconds. Safety first!
if threshold.to_i < 3
  threshold = 3
end

# Check - does that socket exist?
unless File.exist?(socket)
  puts "Socket file not found: #{socket}"
  exit 1
end

# Poll the given socket every THRESHOLD seconds as specified above.
puts "Running infinite loop. Use CTRL+C to exit."
puts "------------------------------------------"
loop do
  Raindrops::Linux.unix_listener_stats([socket]).each do |addr, stats|
    puts DateTime.now.to_s + " Active: " + stats.active.to_s + " Queued: " + stats.queued.to_s
  end
  sleep threshold
end
```

## Registry

### Registry Disk Space Usage by Project

As a GitLab administrator, you may need to reduce disk space consumption.
A common culprit is Docker Registry images that are no longer in use. To find
the storage broken down by each project, run the following in the
[GitLab Rails console](../troubleshooting/navigating_gitlab_via_rails_console.md):

```ruby
projects_and_size = [["project_id", "creator_id", "registry_size_bytes", "project path"]]
# You need to specify the projects that you want to look through. You can get these in any manner.
projects = Project.last(100)

projects.each do |p|
   project_total_size = 0
   container_repositories = p.container_repositories

   container_repositories.each do |c|
       c.tags.each do |t|
          project_total_size = project_total_size + t.total_size unless t.total_size.nil?
       end
   end

   if project_total_size > 0
      projects_and_size << [p.project_id, p.creator.id, project_total_size, p.full_path]
   end
end

# projects_and_size is filled out now
# maybe print it as comma separated output?
projects_and_size.each do |ps|
   puts "%s,%s,%s,%s" % ps
end
```

### Run the Cleanup policy now

Find this content in the [Container Registry troubleshooting docs](../packages/container_registry.md#run-the-cleanup-policy-now).

## Sidekiq

This content has been moved to the [Troubleshooting Sidekiq docs](./sidekiq.md).

## Redis

### Connect to Redis (omnibus)

```shell
/opt/gitlab/embedded/bin/redis-cli -s /var/opt/gitlab/redis/redis.socket
```

## LFS

### Get information about LFS objects and associated project

```ruby
o=LfsObject.find_by(oid: "<oid>")
p=Project.find(LfsObjectsProject.find_by_lfs_object_id(o.id).project_id)
```

You can then delete these records from the database with:

```ruby
LfsObjectsProject.find_by_lfs_object_id(o.id).destroy
o.destroy
```

You would also want to combine this with deleting the LFS file in the LFS storage
area on disk. It remains to be seen exactly how or whether the deletion is useful, however.

## Decryption Problems

### Bad Decrypt Script (for encrypted variables)

This content has been converted to a Rake task, see the [Doctor Rake tasks docs](../raketasks/doctor.md).

As an example of repairing, if `ProjectImportData Bad count:` is detected and the decision is made to delete the
encrypted credentials to allow manual reentry:

```ruby
  # Find the ids of the corrupt ProjectImportData objects
  total = 0
  bad = []
  ProjectImportData.find_each do |data|
    begin
      total += 1
      data.credentials
    rescue => e
      bad << data.id
    end
  end

  puts "Bad count: #{bad.count} / #{total}"

  # See the bad ProjectImportData ids
  bad

  # Remove the corrupted credentials
  import_data = ProjectImportData.where(id: bad)
  import_data.each do |data|
    data.update_columns({ encrypted_credentials: nil, encrypted_credentials_iv: nil, encrypted_credentials_salt: nil})
  end
```

If `User OTP Secret Bad count:` is detected. For each user listed disable/enable
two-factor authentication.

The following script will search in some of the tables for encrypted tokens that are
causing decryption errors, and update or reset as needed:

```shell
wget -O /tmp/encrypted-tokens.rb https://gitlab.com/snippets/1876342/raw
gitlab-rails runner /tmp/encrypted-tokens.rb
```

### Decrypt Script for encrypted tokens

This content has been converted to a Rake task, see the [Doctor Rake tasks docs](../raketasks/doctor.md).
