GitLab Rails Console Cheat Sheet (FREE SELF)

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 first check our guide on navigating our Rails console, and your support options, before attempting to use this information.

WARNING: 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.

WARNING: 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 continue to work as they should and, if needed, update the script for the latest version of GitLab.

Find specific methods for an object

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

Find method source

instance_of_object.method(:foo).source_location

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

Attributes

View available attributes, formatted using pretty print (pp).

For example, determine what attributes contain users' names and email addresses:

u = User.find_by_username('someuser')
pp u.attributes

Partial output:

{"id"=>1234,
 "email"=>"someuser@example.com",
 "sign_in_count"=>99,
 "name"=>"S User",
 "username"=>"someuser",
 "first_name"=>nil,
 "last_name"=>nil,
 "bot_type"=>nil}

Then make use of the attributes, testing SMTP, for example:

e = u.email
n = u.name
Notify.test_email(e, "Test email for #{n}", 'Test email').deliver_now
#
Notify.test_email(u.email, "Test email for #{u.name}", 'Test email').deliver_now

Query the database using an ActiveRecord Model

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

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

View all keys in cache

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

Profile a page

url = '<url/of/the/page>'

# 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>')
Gitlab::Profiler.with_user(admin) { app.get(url) }

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

logger = Logger.new($stdout)
admin = User.find_by_username('<admin-username>')
Gitlab::Profiler.profile('<url/of/the/page>', logger: logger, user: admin)

Time an operation

# 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

# Regular output
Feature.all

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

Command Line

Check the GitLab version fast

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

Debugging SSH

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

Debugging over HTTPS

GIT_CURL_VERBOSE=1 GIT_TRACE=1 git clone <repository>

Projects

Clear a project's cache

ProjectCacheWorker.perform_async(project.id)

Expire the .exists? cache

project.repository.expire_exists_cache

Make all projects private

Project.update_all(visibility_level: 0)

Find projects that are pending deletion

#
# This section lists 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 does)
#
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

Destroy a project

project = Project.find_by_full_path('<project_path>')
user = User.find_by_username('<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

p = Project.find_by_full_path('<project_path>')
u = User.find_by_username('<username>')
::Projects::UnlinkForkService.new(p, u).execute

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

# 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

p = Project.find_by_full_path('<project_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("<new_namespace>")

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

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

# ID is 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:

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_integration.update_attribute(:password, '<your-new-password>')
end

Bulk update push rules for all projects

For example, enable Check whether the commit author is a GitLab user and Do not allow users to remove Git tags with git push checkboxes, and create a filter for allowing commits from a specific e-mail domain only:

Project.find_each do |p|
  pr = p.push_rule || PushRule.new(project: p)
  # Check whether the commit author is a GitLab user
  pr.member_check = true
  # Do not allow users to remove Git tags with `git push`
  pr.deny_delete_tag = true
  # Commit author's email
  pr.author_email_regex = '@domain\.com$'
  pr.save!
end

Bulk update to change all the Jira integrations to Jira instance-level values

To change all Jira project to use the instance-level integration settings:

1. In a Rails console:

   jira_integration_instance_id = Integrations::Jira.find_by(instance: true).id
   Integrations::Jira.where(active: true, instance: false, template: false, inherit_from_id: nil).find_each do |integration|
     integration.update_attribute(:inherit_from_id, jira_integration_instance_id)
   end
   

2. Modify and save again the instance-level integration from the UI to propagate the changes to all the group-level and project-level integrations.

Bulk update to disable the Slack Notification service

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

# 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 the displayed size may still show old sizes or commit numbers. To force an update, do:

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

# check the total artifact storage space separately
builds_with_artifacts = p.builds.with_downloadable_artifacts.all

artifact_storage = 0
builds_with_artifacts.find_each do |build|
  artifact_storage += build.artifacts_size
end

puts "#{artifact_storage} bytes"

Identify deploy keys associated with blocked and non-member users

When the user who created a deploy key is blocked or removed from the project, the key can no longer be used to push to protected branches in a private project (see issue #329742). The following script identifies unusable deploy keys:

ghost_user_id = User.ghost.id

DeployKeysProject.with_write_access.find_each do |deploy_key_mapping|
  project = deploy_key_mapping.project
  deploy_key = deploy_key_mapping.deploy_key
  user = deploy_key.user

  access_checker = Gitlab::DeployKeyAccess.new(deploy_key, container: project)

  # can_push_for_ref? tests if deploy_key can push to default branch, which is likely to be protected
  can_push = access_checker.can_do_action?(:push_code)
  can_push_to_default = access_checker.can_push_for_ref?(project.repository.root_ref)

  next if access_checker.allowed? && can_push && can_push_to_default

  if user.nil? || user.id == ghost_user_id
    username = 'none'
    state = '-'
  else
    username = user.username
    user_state = user.state
  end

  puts "Deploy key: #{deploy_key.id}, Project: #{project.full_path}, Can push?: " + (can_push ? 'YES' : 'NO') +
       ", Can push to default branch #{project.repository.root_ref}?: " + (can_push_to_default ? 'YES' : 'NO') +
       ", User: #{username}, User state: #{user_state}"
end

Find projects using an SQL query

Find and store an array of projects based on an SQL query:

# Finds projects that end with '%ject'
projects = Project.find_by_sql("SELECT * FROM projects WHERE name LIKE '%ject'")
=> [#<Project id:12 root/my-first-project>>, #<Project id:13 root/my-second-project>>]

Wikis

Recreate

WARNING: This is a destructive operation, the Wiki becomes empty.

A Projects Wiki can be recreated by this command:

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

p = Project.find_by_full_path('<username-or-group>/<project-name>')

Issues::RelativePositionRebalancingService.new(p.root_namespace.all_projects).execute

Imports and exports

Import a project

# 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:

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:

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

Clear the cache:

sudo gitlab-rake cache:clear

Export a project

It's typically recommended to export a project through the web interface or through the API. In situations where this is not working as expected, it may be preferable to export a project directly via the Rails console:

user = User.find_by_username('<username>')
# Sufficient permissions needed
# Read https://docs.gitlab.com/ee/user/permissions.html#project-members-permissions

project = Project.find_by_full_path('<username-or-group>/<project-name')
Projects::ImportExport::ExportService.new(project, user).execute

If this all runs successfully, you see an output like the following before being returned to the Rails console prompt:

=> nil

The exported project is located within a .tar.gz file in /var/opt/gitlab/gitlab-rails/uploads/-/system/import_export_upload/export_file/.

If this fails, enable verbose logging, repeat the above procedure after, and report the output to GitLab Support.

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 describes how you can end up in this state without a force push. Another cause can be a misconfigured server hook that changes a HEAD ref via a git reset operation.

If you look at the output from the sample code below for the target branch, you see a discontinuity in the from/to commits as you step through the output. The commit_from of each new push should equal the commit_to of the previous push. A break in that sequence indicates one or more commits have been "lost" from the repository history.

The following example checks the last 100 pushes and prints the commit_from and commit_to entries:

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

Example output showing break in sequence at line 4:

master               f21b07713251e04575908149bdc8ac1f105aabc3...6bc56c1f46244792222f6c85b11606933af171de (root)

Mirrors

Find mirrors with "bad decrypt" errors

This content has been converted to a Rake task, see the Doctor Rake tasks docs.

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:

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

Create new user

u = User.new(username: 'test_user', email: 'test@example.com', name: 'Test User', password: 'password', password_confirmation: 'password')
u.skip_confirmation! # Use it only if you wish user to be automatically confirmed. If skipped, user receives confirmation e-mail
u.save!

Skip reconfirmation

user = User.find_by_username('<username>')
user.skip_reconfirmation!

Disable 2fa for single user

user = User.find_by_username('<username>')
user.disable_two_factor!

Active users & Historical users

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

# Users taking a seat on the instance
User.billable.count

# The historical max on the instance as of the past year
::HistoricalData.max_historical_user_count(from: 1.year.ago.beginning_of_day, to: Time.current.end_of_day)

Using cURL and jq (up to a max 100, see the pagination docs):

curl --silent --header "Private-Token: ********************" \
     "https://gitlab.example.com/api/v4/users?per_page=100&active" | jq --compact-output '.[] | [.id,.name,.username]'

Update Daily Billable & Historical users

# Forces recount of historical (max) users
::HistoricalDataWorker.new.perform

# Forces recount of daily billable users
identifier = Analytics::UsageTrends::Measurement.identifiers[:billable_users]
::Analytics::UsageTrends::CounterJobWorker.new.perform(identifier, User.minimum(:id), User.maximum(:id), Time.zone.now)

Block or Delete Users that have no projects or groups

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

# How many users are removed?
users.count

# If that count looks sane:

# You can either block the users:
users.each { |user|  user.blocked? ? nil  : 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

Deactivate Users that have no recent activity

days_inactive = 90
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.deactivate!
end

Block Users that have no recent activity

days_inactive = 90
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 a user's max permissions for project/group

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

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

Groups

Transfer group to another location

user = User.find_by_username('<username>')
group = Group.find_by_name("<group_name>")
parent_group = Group.find_by(id: "<group_id>")
service = ::Groups::TransferService.new(group, user)
service.execute(parent_group)

Count unique users in a group and subgroups

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

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

GroupDestroyWorker.perform_async(group_id, user_id)

Modify group project creation

# 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

Modify group - disable 2FA requirement

WARNING: When disabling the 2FA Requirement on a subgroup, the whole parent group (including all subgroups) is affected by this change.

group = Group.find_by_path_or_name('group-name')
group.require_two_factor_authentication=false
group.save

Authentication

Re-enable standard web sign-in form

Re-enable the standard username and password-based sign-in form if it was disabled as a Sign-in restriction.

You can use this method when a configured external authentication provider (through SSO or an LDAP configuration) is facing an outage and direct sign-in access to GitLab is required.

Gitlab::CurrentSettings.update!(password_authentication_enabled_for_web: true)

SCIM

end

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

emails.each do |e|
  delete_bad_scim(e,'<group-path>')
end

Find groups using an SQL query

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

License.current.feature_available?(:jira_dev_panel_integration)

Check if a project feature is available in a project

Features listed in license.rb.

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

Add a license through the console

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

This is needed for example in a known edge-case with expired license and multiple LDAP servers.

Remove licenses

To clean up the License History table:

TYPE = :trial?
# or :expired?

License.select(&TYPE).each(&:destroy!)

# or even License.all.each(&:destroy!)

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:

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

Redis

Connect to Redis (omnibus)

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

LFS

Get information about LFS objects and associated project

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:

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.

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:

  # 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 searches in some of the tables for encrypted tokens that are causing decryption errors, and update or reset as needed:

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

Sync individual repository now

project = Project.find_by_full_path('<group/project>')

Geo::RepositorySyncService.new(project).execute

Blob types newer than uploads/artifacts/LFS

• Packages::PackageFile
• Terraform::StateVersion
• MergeRequestDiff

Packages::PackageFile is used in the following examples, but things generally work the same for the other Blob types.

The Replicator

The main kinds of classes are Registry, Model, and Replicator. If you have an instance of one of these classes, you can get the others. The Registry and Model mostly manage PostgreSQL DB state. The Replicator knows how to replicate/verify (or it can call a service to do it):

model_record = Packages::PackageFile.last
model_record.replicator.registry.replicator.model_record # just showing that these methods exist

Replicate a package file, synchronously, given an ID

model_record = Packages::PackageFile.find(id)
model_record.replicator.send(:download)

Replicate a package file, synchronously, given a registry ID

registry = Geo::PackageFileRegistry.find(registry_id)
registry.replicator.send(:download)

Verify package files on the secondary manually

This iterates over all package files on the secondary, looking at the verification_checksum stored in the database (which came from the primary) and then calculate this value on the secondary to check if they match. This does not change anything in the UI:

# Run on secondary
status = {}

Packages::PackageFile.find_each do |package_file|
  primary_checksum = package_file.verification_checksum
  secondary_checksum = Packages::PackageFile.hexdigest(package_file.file.path)
  verification_status = (primary_checksum == secondary_checksum)

  status[verification_status.to_s] ||= []
  status[verification_status.to_s] << package_file.id
end

# Count how many of each value we get
status.keys.each {|key| puts "#{key} count: #{status[key].count}"}

# See the output in its entirety
status

Repository types newer than project/wiki repositories

• SnippetRepository
• GroupWikiRepository

SnippetRepository is used in the examples below, but things generally work the same for the other Repository types.

The Replicator

The main kinds of classes are Registry, Model, and Replicator. If you have an instance of one of these classes, you can get the others. The Registry and Model mostly manage PostgreSQL DB state. The Replicator knows how to replicate/verify (or it can call a service to do it).

model_record = SnippetRepository.last
model_record.replicator.registry.replicator.model_record # just showing that these methods exist

Replicate a snippet repository, synchronously, given an ID

model_record = SnippetRepository.find(id)
model_record.replicator.send(:sync_repository)

Replicate a snippet repository, synchronously, given a registry ID

registry = Geo::SnippetRepositoryRegistry.find(registry_id)
registry.replicator.send(:sync_repository)

Kubernetes integration

Find cluster:

cluster = Clusters::Cluster.find(1)
cluster = Clusters::Cluster.find_by(name: 'cluster_name')

Delete cluster without associated resources:

# Find users with the Administrator role
user = User.find_by(username: 'admin_user')

# Find the cluster with the ID
cluster = Clusters::Cluster.find(1)

# Delete the cluster
Clusters::DestroyService.new(user).execute(cluster)

Elasticsearch

Configuration attributes

Open the rails console (gitlab rails c) and run the following command to see all the available attributes:

ApplicationSetting.last.attributes

Among other attributes, the output contains all the settings available in the Elasticsearch Integration page, such as elasticsearch_indexing, elasticsearch_url, elasticsearch_replicas, and elasticsearch_pause_indexing.

Setting attributes

You can then set anyone of Elasticsearch integration settings by issuing a command similar to:

ApplicationSetting.last.update(elasticsearch_url: '<your ES URL and port>')

#or

ApplicationSetting.last.update(elasticsearch_indexing: false)

Getting attributes

You can then check if the settings have been set in the Elasticsearch Integration page or in the rails console by issuing:

Gitlab::CurrentSettings.elasticsearch_url

#or

Gitlab::CurrentSettings.elasticsearch_indexing
