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 ``` ## Attributes View available attributes, formatted using pretty print (`pp`). For example, determine what attributes contain users' names and email addresses: ```ruby u = User.find_by_username('someuser') pp u.attributes ``` Partial output: ```plaintext {"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](https://docs.gitlab.com/omnibus/settings/smtp.html#testing-the-smtp-configuration): ```ruby 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 ```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 { } # A breakdown of multiple operations Benchmark.bm do |x| x.report(:label1) { } x.report(:label2) { } 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 ``` ### Debugging over HTTPS ```shell GIT_CURL_VERBOSE=1 GIT_TRACE=1 git clone ``` ## 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 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 ``` ### 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, '') 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('/') pp p.statistics p.statistics.refresh! pp p.statistics # compare with earlier values ``` ## Wikis ### Recreate CAUTION: **Caution:** This is a destructive operation, the Wiki will be empty. A Projects Wiki can be recreated by this command: ```ruby p = Project.find_by_full_path('/') ### 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('/') 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// /var/opt/gitlab/git-data/repositories// ``` Make sure the permissions are correct: ```shell chown -R git:git .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 User.billable.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: '') 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 ### Transfer group to another location ```ruby user = User.find_by_username('') group = Group.find_by_name("") parent_group = Group.find_by(id: "") # empty string amounts to root as parent service = ::Groups::TransferService.new(group, user) service.execute(parent_group) ``` ### 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 . ```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('') m = p.merge_requests.find_by(iid: ) u = User.find_by_username('') MergeRequests::PostMergeService.new(p, u).execute(m) ``` ### Delete a merge request ```ruby u = User.find_by_username('') p = Project.find_by_full_path('/') m = p.merge_requests.find_by(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 . ```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 . ```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('/') p.feature_available?(:jira_dev_panel_integration) ``` ### Add a license through the console ```ruby 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 " 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: "") 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). ## Geo ### Artifacts #### Find failed artifacts ```ruby Geo::JobArtifactRegistry.failed ``` #### Download artifact ```ruby Gitlab::Geo::JobArtifactDownloader.new(:job_artifact, ).execute ``` #### Get a count of the synced artifacts ```ruby Geo::JobArtifactRegistry.synced.count ``` #### Find `ID` of synced artifacts that are missing on primary ```ruby Geo::JobArtifactRegistry.synced.missing_on_primary.pluck(:artifact_id) ``` ### Repository verification failures #### Get the number of verification failed repositories ```ruby Geo::ProjectRegistry.verification_failed('repository').count ``` #### Find the verification failed repositories ```ruby Geo::ProjectRegistry.verification_failed('repository') ``` ### Find repositories that failed to sync ```ruby Geo::ProjectRegistry.sync_failed('repository') ``` ### Resync repositories #### Queue up all repositories for resync. Sidekiq will handle each sync ```ruby Geo::ProjectRegistry.update_all(resync_repository: true, resync_wiki: true) ``` #### Sync individual repository now ```ruby project = Project.find_by_full_path('') Geo::RepositorySyncService.new(project).execute ``` ### Generate usage ping #### Generate or get the cached usage ping ```ruby Gitlab::UsageData.to_json ``` #### Generate a fresh new usage ping This will also refresh the cached usage ping displayed in the admin area ```ruby Gitlab::UsageData.to_json(force_refresh: true) ```
