+# Issue closing pattern
+
+>**Note:**
+This is the administration documentation.
+There is a separate [user documentation] on issue closing pattern.
+
+When a commit or merge request resolves one or more issues, it is possible to
+automatically have these issues closed when the commit or merge request lands
+in the project's default branch.
+
+## Change the issue closing pattern
+
+In order to change the pattern you need to have access to the server that GitLab
+is installed on.
+
+The default pattern can be located in [gitlab.yml.example] under the
+"Automatic issue closing" section.
+
+> **Tip:**
+You are advised to use http://rubular.com to test the issue closing pattern.
+Because Rubular doesn't understand `%{issue_ref}`, you can replace this by
+`#\d+` when testing your patterns, which matches only local issue references like `#123`.
+
+**For Omnibus installations**
+
+1. Open `/etc/gitlab/gitlab.rb` with your editor.
+1. Change the value of `gitlab_rails['issue_closing_pattern']` to a regular
+   expression of your liking:
+
+    ```ruby
+    gitlab_rails['issue_closing_pattern'] = "((?:[Cc]los(?:e[sd]|ing)|[Ff]ix(?:e[sd]|ing)?) +(?:(?:issues? +)?%{issue_ref}(?:(?:, *| +and +)?))+)"
+    ```
+1. [Reconfigure] GitLab for the changes to take effect.
+
+**For installations from source**
+
+1. Open `gitlab.yml` with your editor.
+1. Change the value of `issue_closing_pattern`:
+
+    ```yaml
+    issue_closing_pattern: "((?:[Cc]los(?:e[sd]|ing)|[Ff]ix(?:e[sd]|ing)?) +(?:(?:issues? +)?%{issue_ref}(?:(?:, *| +and +)?))+)"
+    ```
+
+1. [Restart] GitLab for the changes to take effect.

-# Issue closing pattern
+This document was split into:
 
-When a commit or merge request resolves one or more issues, it is possible to automatically have these issues closed when the commit or merge request lands in the project's default branch.
-
-If a commit message or merge request description contains a sentence matching the regular expression below, all issues referenced from
-the matched text will be closed. This happens when the commit is pushed to a project's default branch, or when a commit or merge request is merged into there.
-
-When not specified, the default `issue_closing_pattern` as shown below will be used:
-
-```bash
-((?:[Cc]los(?:e[sd]?|ing)|[Ff]ix(?:e[sd]|ing)?|[Rr]esolv(?:e[sd]?|ing))(:?) +(?:(?:issues? +)?%{issue_ref}(?:(?:, *| +and +)?)|([A-Z][A-Z0-9_]+-\d+))+)
-```
-
-Here, `%{issue_ref}` is a complex regular expression defined inside GitLab, that matches a reference to a local issue (`#123`), cross-project issue (`group/project#123`) or a link to an issue (`https://gitlab.example.com/group/project/issues/123`).
-
-For example:
-
-```
-git commit -m "Awesome commit message (Fix #20, Fixes #21 and Closes group/otherproject#22). This commit is also related to #17 and fixes #18, #19 and https://gitlab.example.com/group/otherproject/issues/23."
-```
-
-will close `#18`, `#19`, `#20`, and `#21` in the project this commit is pushed to, as well as `#22` and `#23` in group/otherproject. `#17` won't be closed as it does not match the pattern. It also works with multiline commit messages.
-
-Tip: you can test this closing pattern at [http://rubular.com][1]. Use this site
-to test your own patterns.
-Because Rubular doesn't understand `%{issue_ref}`, you can replace this by `#\d+` in testing, which matches only local issue references like `#123`.
-
-## Change the pattern
-
-For Omnibus installs you can change the default pattern in `/etc/gitlab/gitlab.rb`:
-
-```
-issue_closing_pattern: '((?:[Cc]los(?:e[sd]|ing)|[Ff]ix(?:e[sd]|ing)?) +(?:(?:issues? +)?%{issue_ref}(?:(?:, *| +and +)?))+)'
-```
-
-For manual installs you can customize the pattern in [gitlab.yml][0] using the `issue_closing_pattern` key.

+# Merge Request Performance Guidelines
+
+To ensure a merge request does not negatively impact performance of GitLab
+_every_ merge request **must** adhere to the guidelines outlined in this
+document. There are no exceptions to this rule unless specifically discussed
+with and agreed upon by merge request endbosses and performance specialists.
+
+To measure the impact of a merge request you can use
+[Sherlock](profiling.md#sherlock). It's also highly recommended that you read
+the following guides:
+
+* [Performance Guidelines](performance.md)
+* [What requires downtime?](what_requires_downtime.md)
+
+## Impact Analysis
+
+**Summary:** think about the impact your merge request may have on performance
+and those maintaining a GitLab setup.
+
+Any change submitted can have an impact not only on the application itself but
+also those maintaining it and those keeping it up and running (e.g. production
+engineers). As a result you should think carefully about the impact of your
+merge request on not only the application but also on the people keeping it up
+and running.
+
+Can the queries used potentially take down any critical services and result in
+engineers being woken up in the night? Can a malicious user abuse the code to
+take down a GitLab instance? Will my changes simply make loading a certain page
+slower? Will execution time grow exponentially given enough load or data in the
+database?
+
+These are all questions one should ask themselves before submitting a merge
+request. It may sometimes be difficult to assess the impact, in which case you
+should ask a performance specialist to review your code. See the "Reviewing"
+section below for more information.
+
+## Performance Review
+
+**Summary:** ask performance specialists to review your code if you're not sure
+about the impact.
+
+Sometimes it's hard to assess the impact of a merge request. In this case you
+should ask one of the merge request (mini) endbosses to review your changes. You
+can find a list of these endbosses at <https://about.gitlab.com/team/>. An
+endboss in turn can request a performance specialist to review the changes.
+
+## Query Counts
+
+**Summary:** a merge request **should not** increase the number of executed SQL
+queries unless absolutely necessary.
+
+The number of queries executed by the code modified or added by a merge request
+must not increase unless absolutely necessary. When building features it's
+entirely possible you will need some extra queries, but you should try to keep
+this at a minimum.
+
+As an example, say you introduce a feature that updates a number of database
+rows with the same value. It may be very tempting (and easy) to write this using
+the following pseudo code:
+
+```ruby
+objects_to_update.each do |object|
+  object.some_field = some_value
+  object.save
+end
+```
+
+This will end up running one query for every object to update. This code can
+easily overload a database given enough rows to update or many instances of this
+code running in parallel. This particular problem is known as the
+["N+1 query problem"](http://guides.rubyonrails.org/active_record_querying.html#eager-loading-associations).
+
+In this particular case the workaround is fairly easy:
+
+```ruby
+objects_to_update.update_all(some_field: some_value)
+```
+
+This uses ActiveRecord's `update_all` method to update all rows in a single
+query. This in turn makes it much harder for this code to overload a database.
+
+## Executing Queries in Loops
+
+**Summary:** SQL queries **must not** be executed in a loop unless absolutely
+necessary.
+
+Executing SQL queries in a loop can result in many queries being executed
+depending on the number of iterations in a loop. This may work fine for a
+development environment with little data, but in a production environment this
+can quickly spiral out of control.
+
+There are some cases where this may be needed. If this is the case this should
+be clearly mentioned in the merge request description.
+
+## Eager Loading
+
+**Summary:** always eager load associations when retrieving more than one row.
+
+When retrieving multiple database records for which you need to use any
+associations you **must** eager load these associations. For example, if you're
+retrieving a list of blog posts and you want to display their authors you
+**must** eager load the author associations.
+
+In other words, instead of this:
+
+```ruby
+Post.all.each do |post|
+  puts post.author.name
+end
+```
+
+You should use this:
+
+```ruby
+Post.all.includes(:author).each do |post|
+  puts post.author.name
+end
+```
+
+## Memory Usage
+
+**Summary:** merge requests **must not** increase memory usage unless absolutely
+necessary.
+
+A merge request must not increase the memory usage of GitLab by more than the
+absolute bare minimum required by the code. This means that if you have to parse
+some large document (e.g. an HTML document) it's best to parse it as a stream
+whenever possible, instead of loading the entire input into memory. Sometimes
+this isn't possible, in that case this should be stated explicitly in the merge
+request.
+
+## Lazy Rendering of UI Elements
+
+**Summary:** only render UI elements when they're actually needed.
+
+Certain UI elements may not always be needed. For example, when hovering over a
+diff line there's a small icon displayed that can be used to create a new
+comment. Instead of always rendering these kind of elements they should only be
+rendered when actually needed. This ensures we don't spend time generating
+Haml/HTML when it's not going to be used.
+
+## Instrumenting New Code
+
+**Summary:** always add instrumentation for new classes, modules, and methods.
+
+Newly added classes, modules, and methods must be instrumented. This ensures
+we can track the performance of this code over time.
+
+For more information see [Instrumentation](instrumentation.md). This guide
+describes how to add instrumentation and where to add it.
+
+## Use of Caching
+
+**Summary:** cache data in memory or in Redis when it's needed multiple times in
+a transaction or has to be kept around for a certain time period.
+
+Sometimes certain bits of data have to be re-used in different places during a
+transaction. In these cases this data should be cached in memory to remove the
+need for running complex operations to fetch the data. You should use Redis if
+data should be cached for a certain time period instead of the duration of the
+transaction.
+
+For example, say you process multiple snippets of text containiner username
+mentions (e.g. `Hello @alice` and `How are you doing @alice?`). By caching the
+user objects for every username we can remove the need for running the same
+query for every mention of `@alice`.
+
+Caching data per transaction can be done using
+[RequestStore](https://github.com/steveklabnik/request_store). Caching data in
+Redis can be done using [Rails' caching
+system](http://guides.rubyonrails.org/caching_with_rails.html).

+a max value of 2,147,483,647. Be aware of this when creating a column that will

+
+### 4. Get latest code
+
+```bash
+sudo -u git -H git fetch --all
+sudo -u git -H git checkout -- db/schema.rb # local changes will be restored automatically
+```
+
+For GitLab Community Edition:
+
+```bash
+sudo -u git -H git checkout 8-12-stable
+```
+
+OR
+
+For GitLab Enterprise Edition:
+
+```bash
+sudo -u git -H git checkout 8-12-stable-ee
+```
+
+### 5. Update gitlab-shell
+
+```bash
+cd /home/git/gitlab-shell
+sudo -u git -H git fetch --all --tags
+sudo -u git -H git checkout v3.6.0
+```
+
+### 6. Update gitlab-workhorse
+
+Install and compile gitlab-workhorse. This requires
+[Go 1.5](https://golang.org/dl) which should already be on your system from
+GitLab 8.1.
+
+```bash
+cd /home/git/gitlab-workhorse
+sudo -u git -H git fetch --all
+sudo -u git -H git checkout v0.8.2
+sudo -u git -H make
+```
+
+### 7. Install libs, migrations, etc.
+
+```bash
+cd /home/git/gitlab
+
+# MySQL installations (note: the line below states '--without postgres')
+sudo -u git -H bundle install --without postgres development test --deployment
+
+# PostgreSQL installations (note: the line below states '--without mysql')
+sudo -u git -H bundle install --without mysql development test --deployment
+
+# Optional: clean up old gems
+sudo -u git -H bundle clean
+
+# Run database migrations
+sudo -u git -H bundle exec rake db:migrate RAILS_ENV=production
+
+# Clean up assets and cache
+sudo -u git -H bundle exec rake assets:clean assets:precompile cache:clear RAILS_ENV=production
+```
+
+### 8. Update configuration files
+
+#### New configuration options for `gitlab.yml`
+
+There are new configuration options available for [`gitlab.yml`](config/gitlab.yml.example). View them with the command below and apply them manually to your current `gitlab.yml`:
+
+```sh
+git diff origin/8-11-stable:config/gitlab.yml.example origin/8-12-stable:config/gitlab.yml.example
+```
+
+#### Git configuration
+
+Configure Git to generate packfile bitmaps (introduced in Git 2.0) on
+the GitLab server during `git gc`.
+
+```sh
+sudo -u git -H git config --global repack.writeBitmaps true
+```
+
+#### Nginx configuration
+
+Ensure you're still up-to-date with the latest NGINX configuration changes:
+
+```sh
+# For HTTPS configurations
+git diff origin/8-11-stable:lib/support/nginx/gitlab-ssl origin/8-12-stable:lib/support/nginx/gitlab-ssl
+
+# For HTTP configurations
+git diff origin/8-11-stable:lib/support/nginx/gitlab origin/8-12-stable:lib/support/nginx/gitlab
+```
+
+If you are using Apache instead of NGINX please see the updated [Apache templates].
+Also note that because Apache does not support upstreams behind Unix sockets you
+will need to let gitlab-workhorse listen on a TCP port. You can do this
+via [/etc/default/gitlab].
+
+[Apache templates]: https://gitlab.com/gitlab-org/gitlab-recipes/tree/master/web-server/apache
+[/etc/default/gitlab]: https://gitlab.com/gitlab-org/gitlab-ce/blob/8-12-stable/lib/support/init.d/gitlab.default.example#L38
+
+#### SMTP configuration
+
+If you're installing from source and use SMTP to deliver mail, you will need to add the following line
+to config/initializers/smtp_settings.rb:
+
+```ruby
+ActionMailer::Base.delivery_method = :smtp
+```
+
+See [smtp_settings.rb.sample] as an example.
+
+[smtp_settings.rb.sample]:  https://gitlab.com/gitlab-org/gitlab-ce/blob/8-12-stable/config/initializers/smtp_settings.rb.sample#L13?
+
+#### Init script
+
+Ensure you're still up-to-date with the latest init script changes:
+
+    sudo cp lib/support/init.d/gitlab /etc/init.d/gitlab
+
+### 9. Start application
+
+    sudo service gitlab start
+    sudo service nginx restart
+
+### 10. Check application status
+
+Check if GitLab and its environment are configured correctly:
+
+    sudo -u git -H bundle exec rake gitlab:env:info RAILS_ENV=production
+
+To make sure you didn't miss anything run a more thorough check:
+
+    sudo -u git -H bundle exec rake gitlab:check RAILS_ENV=production
+
+If all items are green, then congratulations, the upgrade is complete!
+
+## Things went south? Revert to previous version (8.11)
+
+### 1. Revert the code to the previous version
+
+Follow the [upgrade guide from 8.10 to 8.11](8.10-to-8.11.md), except for the
+database migration (the backup is already migrated to the previous version).
+
+### 2. Restore from the backup
+
+```bash
+cd /home/git/gitlab
+sudo -u git -H bundle exec rake gitlab:backup:restore RAILS_ENV=production
+```
+
+If you have more than one backup `*.tar` file(s) please add `BACKUP=timestamp_of_backup` to the command above.

+# Two-Factor Authentication
+
+## Recovery options
+
+If you lose your code generation device (such as your mobile phone) and you need
+to disable two-factor authentication on your account, you have several options.
+
+### Use a saved recovery code
+
+When you enabled two-factor authentication for your account, a series of
+recovery codes were generated. If you saved those codes somewhere safe, you
+may use one to sign in.
+
+First, enter your username/email and password on the GitLab sign in page. When
+prompted for a two-factor code, enter one of the recovery codes you saved
+previously.
+
+> **Note:** Once a particular recovery code has been used, it cannot be used again.
+  You may still use the other saved recovery codes at a later time.
+
+### Generate new recovery codes using SSH
+
+It's not uncommon for users to forget to save the recovery codes when enabling
+two-factor authentication. If you have an SSH key added to your GitLab account,
+you can generate a new set of recovery codes using SSH.
+
+Run `ssh git@gitlab.example.com 2fa_recovery_codes`. You will be prompted to
+confirm that you wish to generate new codes. If you choose to continue, any
+previously saved codes will be invalidated.
+
+```bash
+$ ssh git@gitlab.example.com 2fa_recovery_codes
+Are you sure you want to generate new two-factor recovery codes?
+Any existing recovery codes you saved will be invalidated. (yes/no)
+yes
+
+Your two-factor authentication recovery codes are:
+
+119135e5a3ebce8e
+11f6v2a498810dcd
+3924c7ab2089c902
+e79a3398bfe4f224

+b510e7422e81c947
+20dbed24c5e74663
+df9d3b9403b9c9f0
+
+During sign in, use one of the codes above when prompted for
+your two-factor code. Then, visit your Profile Settings and add
+a new device so you do not lose access to your account again.
+```
+
+Next, go to the GitLab sign in page and enter your username/email and password.
+When prompted for a two-factor code, enter one of the recovery codes obtained
+from the command line output.
+
+> **Note:** After signing in, you should immediately visit your **Profile Settings
+  -> Account** to set up two-factor authentication with a new device.
+
+### Ask a GitLab administrator to disable two-factor on your account
+
+If the above two methods are not possible, you may ask a GitLab global
+administrator to disable two-factor authentication for your account. Please
+be aware that this will temporarily leave your account in a less secure state.
+You should sign in and re-enable two-factor authentication as soon as possible
+after the administrator disables it.

+# Cycle Analytics
+
+> [Introduced][ce-5986] in GitLab 8.12.
+>
+> **Note:**
+This the first iteration of Cycle Analytics, you can follow the following issue
+to track the changes that are coming to this feature: [#20975][ce-20975].
+
+Cycle Analytics measures the time it takes to go from [an idea to production] for
+each project you have. This is achieved by not only indicating the total time it
+takes to reach at that point, but the total time is broken down into the
+multiple stages an idea has to pass through to be shipped.
+
+Cycle Analytics is that it is tightly coupled with the [GitLab flow] and
+calculates a separate median for each stage.
+
+## Overview
+
+You can find the Cycle Analytics page under your project's **Pipelines > Cycle
+Analytics** tab.
+
+![Cycle Analytics landing page](img/cycle_analytics_landing_page.png)
+
+You can see that there are seven stages in total:
+
+- **Issue** (Tracker)
+    - Median time from issue creation until given a milestone or list label
+      (first assignment, any milestone, milestone date or assignee is not required)
+- **Plan** (Board)
+    - Median time from giving an issue a milestone or label until pushing the
+      first commit
+- **Code** (IDE)
+    - Median time from the first commit until the merge request is created
+- **Test** (CI)
+    - Median total test time for all commits/merges
+- **Review** (Merge Request/MR)
+    - Median time from merge request creation until the merge request is merged
+      (closed merge requests won't be taken into account)
+- **Staging** (Continuous Deployment)
+    - Median time from when the merge request got merged until the deploy to
+      production (production is last stage/environment)
+- **Production** (Total)
+   - Sum of all the above stages excluding the Test (CI) time
+
+## How the data is measured
+
+Cycle Analytics records cycle time so only data on the issues that have been
+deployed to production are measured. In case you just started a new project and
+you have not pushed anything to production, then you will not be able to
+properly see the Cycle Analytics of your project.
+
+Specifically, if your CI is not set up and you have not defined a `production`
+[environment], then you will not have any data.
+
+Below you can see in more detail what the various stages of Cycle Analytics mean.
+
+| **Stage** | **Description** |
+| --------- | --------------- |
+| Issue     | Measures the median time between creating an issue and taking action to solve it, by either labeling it or adding it to a milestone, whatever comes first. The label will be tracked only if it already has an [Issue Board list][board] created for it. |
+| Plan      | Measures the median time between the action you took for the previous stage, and pushing the first commit to the repository. To make this change tracked, the pushed commit needs to contain the [issue closing pattern], for example `Closes #xxx`, where `xxx` is the number of the issue related to this commit. If the commit does not contain the issue closing pattern, it is not considered to the measurement time of the stage. |
+| Code      | Measures the median time between pushing a first commit (previous stage) and creating a merge request related to that commit. The key to keep the process tracked is include the [issue closing pattern] to the description of the merge request. |
+| Test      | Measures the median time to run the entire pipeline for that project. It's related to the time GitLab CI takes to run every job for the commits pushed to that merge request defined in the previous stage. It is basically the start->finish time for all pipelines. `master` is not excluded. It does not attempt to track time for any particular stages. |
+| Review    | Measures the median time taken to review the merge request, between its creation and until it's merged. |
+| Staging   | Measures the median time between merging the merge request until the very first deployment to production. It's tracked by the [environment] set to `production` in your GitLab CI configuration. If there isn't a `production` environment, this is not tracked. |
+| Production| The sum of all time taken to run the entire process, from issue creation to deploying the code to production. |
+
+---
+
+Here's a little explanation of how this works behind the scenes:
+
+1. Issues and merge requests are grouped together in pairs, such that for each
+   `<issue, merge request>` pair, the merge request has `Fixes #xxx` for the
+   corresponding issue. All other issues and merge requests are **not** considered.
+
+1. Then the <issue, merge request> pairs are filtered out. Any merge request
+   that has **not** been deployed to production in the last XX days (specified
+   by the UI - default is 90 days) prohibits these pairs from being considered.
+
+1. For the remaining `<issue, merge request>` pairs, we check the information that
+   we need for the stages, like issue creation date, merge request merge time,
+   etc.
+
+To sum up, anything that doesn't follow the [GitLab flow] won't be tracked at all.
+So, if a merge request doesn't close an issue or an issue is not labeled with a
+label present in the Issue Board or assigned a milestone or a project has no
+`production` environment, the Cycle Analytics dashboard won't present any data
+at all.
+
+## Permissions

+- Public projects - anyone can access
+- Private/internal projects - any member (guest level and above) can access

+# Automatic issue closing
+
+>**Note:**
+This is the user docs. In order to change the default issue closing pattern,
+follow the steps in the [administration docs].
+
+When a commit or merge request resolves one or more issues, it is possible to
+automatically have these issues closed when the commit or merge request lands
+in the project's default branch.
+
+If a commit message or merge request description contains a sentence matching
+a certain regular expression, all issues referenced from the matched text will
+be closed. This happens when the commit is pushed to a project's **default**
+branch, or when a commit or merge request is merged into it.
+
+## Default closing pattern value
+
+When not specified, the default issue closing pattern as shown below will be
+used:
+
+```bash
+((?:[Cc]los(?:e[sd]?|ing)|[Ff]ix(?:e[sd]|ing)?|[Rr]esolv(?:e[sd]?|ing))(:?) +(?:(?:issues? +)?%{issue_ref}(?:(?:, *| +and +)?)|([A-Z][A-Z0-9_]+-\d+))+)
+```
+
+Note that `%{issue_ref}` is a complex regular expression defined inside GitLab's
+source code that can match a reference to 1) a local issue (`#123`),
+2) a cross-project issue (`group/project#123`) or 3) a link to an issue
+(`https://gitlab.example.com/group/project/issues/123`).
+
+---
+
+This translates to the following keywords:
+
+- Close, Closes, Closed, Closing, close, closes, closed, closing
+- Fix, Fixes, Fixed, Fixing, fix, fixes, fixed, fixing
+- Resolve, Resolves, Resolved, Resolving, resolve, resolves, resolved, resolving
+
+---
+
+For example the following commit message:
+
+```
+Awesome commit message
+
+Fix #20, Fixes #21 and Closes group/otherproject#22.
+This commit is also related to #17 and fixes #18, #19
+and https://gitlab.example.com/group/otherproject/issues/23.
+```
+
+will close `#18`, `#19`, `#20`, and `#21` in the project this commit is pushed
+to, as well as `#22` and `#23` in group/otherproject. `#17` won't be closed as
+it does not match the pattern. It works with multi-line commit messages as well
+as one-liners when used with `git commit -m`.

+# Merge Requests
+
+Merge requests allow you to exchange changes you made to source code and
+collaborate with other people on the same project.
+
+## Authorization for merge requests
+
+There are two main ways to have a merge request flow with GitLab:
+
+1. Working with [protected branches][] in a single repository
+1. Working with forks of an authoritative project
+
+[Learn more about the authorization for merge requests.](merge_requests/authorization_for_merge_requests.md)
+
+## Cherry-pick changes
+
+Cherry-pick any commit in the UI by simply clicking the **Cherry-pick** button
+in a merged merge requests or a commit.
+
+[Learn more about cherry-picking changes.](merge_requests/cherry_pick_changes.md)
+
+## Merge when build succeeds
+
+When reviewing a merge request that looks ready to merge but still has one or
+more CI builds running, you can set it to be merged automatically when all
+builds succeed. This way, you don't have to wait for the builds to finish and
+remember to merge the request manually.
+
+[Learn more about merging when build succeeds.](merge_requests/merge_when_build_succeeds.md)
+
+## Resolve discussion comments in merge requests reviews
+
+Keep track of the progress during a code review with resolving comments.
+Resolving comments prevents you from forgetting to address feedback and lets
+you hide discussions that are no longer relevant.
+
+[Read more about resolving discussion comments in merge requests reviews.](merge_requests/merge_request_discussion_resolution.md)
+
+## Resolve conflicts
+
+When a merge request has conflicts, GitLab may provide the option to resolve
+those conflicts in the GitLab UI.
+
+[Learn more about resolving merge conflicts in the UI.](merge_requests/resolve_conflicts.md)
+
+## Revert changes
+
+GitLab implements Git's powerful feature to revert any commit with introducing
+a **Revert** button in merge requests and commit details.
+
+[Learn more about reverting changes in the UI](merge_requests/revert_changes.md)
+
+## Merge requests versions
+
+Every time you push to a branch that is tied to a merge request, a new version
+of merge request diff is created. When you visit a merge request that contains
+more than one pushes, you can select and compare the versions of those merge
+request diffs.
+
+[Read more about the merge requests versions.](merge_requests/versions.md)
+
+## Work In Progress merge requests
+
+To prevent merge requests from accidentally being accepted before they're
+completely ready, GitLab blocks the "Accept" button for merge requests that
+have been marked as a **Work In Progress**.
+
+[Learn more about settings a merge request as "Work In Progress".](merge_requests/work_in_progress_merge_requests.md)
+
+## Ignore whitespace changes in Merge Request diff view
+
+If you click the **Hide whitespace changes** button, you can see the diff
+without whitespace changes (if there are any). This is also working when on a
+specific commit page.
+
+![MR diff](merge_requests/img/merge_request_diff.png)
+
+>**Tip:**
+You can append `?w=1` while on the diffs page of a merge request to ignore any
+whitespace changes.
+
+## Tips
+
+Here are some tips that will help you be more efficient with merge requests in
+the command line.
+
+> **Note:**
+This section might move in its own document in the future.
+
+### Checkout merge requests locally
+
+A merge request contains all the history from a repository, plus the additional
+commits added to the branch associated with the merge request. Here's a few
+tricks to checkout a merge request locally.
+
+Please note that you can checkout a merge request locally even if the source
+project is a fork (even a private fork) of the target project.
+
+#### Checkout locally by adding a git alias
+
+Add the following alias to your `~/.gitconfig`:
+
+```
+[alias]
+    mr = !sh -c 'git fetch $1 merge-requests/$2/head:mr-$1-$2 && git checkout mr-$1-$2' -
+```
+
+Now you can check out a particular merge request from any repository and any
+remote. For example, to check out the merge request with ID 5 as shown in GitLab
+from the `upstream` remote, do:
+
+```
+git mr upstream 5
+```
+
+This will fetch the merge request into a local `mr-upstream-5` branch and check
+it out.
+
+#### Checkout locally by modifying `.git/config` for a given repository
+
+Locate the section for your GitLab remote in the `.git/config` file. It looks
+like this:
+
+```
+[remote "origin"]
+  url = https://gitlab.com/gitlab-org/gitlab-ce.git
+  fetch = +refs/heads/*:refs/remotes/origin/*
+```
+
+You can open the file with:
+
+```
+git config -e
+```
+
+Now add the following line to the above section:
+
+```
+fetch = +refs/merge-requests/*/head:refs/remotes/origin/merge-requests/*
+```
+
+In the end, it should look like this:
+
+```
+[remote "origin"]
+  url = https://gitlab.com/gitlab-org/gitlab-ce.git
+  fetch = +refs/heads/*:refs/remotes/origin/*
+  fetch = +refs/merge-requests/*/head:refs/remotes/origin/merge-requests/*
+```
+
+Now you can fetch all the merge requests:
+
+```
+git fetch origin
+
+...
+From https://gitlab.com/gitlab-org/gitlab-ce.git
+ * [new ref]         refs/merge-requests/1/head -> origin/merge-requests/1
+ * [new ref]         refs/merge-requests/2/head -> origin/merge-requests/2
+...
+```
+
+And to check out a particular merge request:
+
+```
+git checkout origin/merge-requests/1
+```

+# Authorization for Merge requests
+
+There are two main ways to have a merge request flow with GitLab:
+
+1. Working with [protected branches] in a single repository.
+1. Working with forks of an authoritative project.
+
+## Protected branch flow
+
+With the protected branch flow everybody works within the same GitLab project.
+
+The project maintainers get Master access and the regular developers get
+Developer access.
+
+The maintainers mark the authoritative branches as 'Protected'.
+
+The developers push feature branches to the project and create merge requests
+to have their feature branches reviewed and merged into one of the protected
+branches.
+
+By default, only users with Master access can merge changes into a protected
+branch.
+
+**Advantages**
+
+- Fewer projects means less clutter.
+- Developers need to consider only one remote repository.
+
+**Disadvantages**
+
+- Manual setup of protected branch required for each new project
+
+## Forking workflow
+
+With the forking workflow the maintainers get Master access and the regular
+developers get Reporter access to the authoritative repository, which prohibits
+them from pushing any changes to it.
+
+Developers create forks of the authoritative project and push their feature
+branches to their own forks.
+
+To get their changes into master they need to create a merge request across
+forks.
+
+**Advantages**
+
+- In an appropriately configured GitLab group, new projects automatically get
+  the required access restrictions for regular developers: fewer manual steps
+  to configure authorization for new projects.
+
+**Disadvantages**
+
+- The project need to keep their forks up to date, which requires more advanced
+  Git skills (managing multiple remotes).

+# Cherry-pick changes
+
+> [Introduced][ce-3514] in GitLab 8.7.
+
+---
+
+GitLab implements Git's powerful feature to [cherry-pick any commit][git-cherry-pick]
+with introducing a **Cherry-pick** button in Merge Requests and commit details.
+
+## Cherry-picking a Merge Request
+
+After the Merge Request has been merged, a **Cherry-pick** button will be available
+to cherry-pick the changes introduced by that Merge Request:
+
+![Cherry-pick Merge Request](img/cherry_pick_changes_mr.png)
+
+---
+
+You can cherry-pick the changes directly into the selected branch or you can opt to
+create a new Merge Request with the cherry-pick changes:
+
+![Cherry-pick Merge Request modal](img/cherry_pick_changes_mr_modal.png)
+
+## Cherry-picking a Commit
+
+You can cherry-pick a Commit from the Commit details page:
+
+![Cherry-pick commit](img/cherry_pick_changes_commit.png)
+
+---
+
+Similar to cherry-picking a Merge Request, you can opt to cherry-pick the changes
+directly into the target branch or create a new Merge Request to cherry-pick the
+changes:
+
+![Cherry-pick commit modal](img/cherry_pick_changes_commit_modal.png)
+
+---
+
+Please note that when cherry-picking merge commits, the mainline will always be the
+first parent. If you want to use a different mainline then you need to do that
+from the command line.
+
+Here is a quick example to cherry-pick a merge commit using the second parent as the
+mainline:
+
+```bash
+git cherry-pick -m 2 7a39eb0

+# Merge When Build Succeeds
+
+When reviewing a merge request that looks ready to merge but still has one or
+more CI builds running, you can set it to be merged automatically when all
+builds succeed. This way, you don't have to wait for the builds to finish and
+remember to merge the request manually.
+
+![Enable](img/merge_when_build_succeeds_enable.png)
+
+When you hit the "Merge When Build Succeeds" button, the status of the merge
+request will be updated to represent the impending merge. If you cannot wait
+for the build to succeed and want to merge immediately, this option is available
+in the dropdown menu on the right of the main button.
+
+Both team developers and the author of the merge request have the option to
+cancel the automatic merge if they find a reason why it shouldn't be merged
+after all.
+
+![Status](img/merge_when_build_succeeds_status.png)
+
+When the build succeeds, the merge request will automatically be merged. When
+the build fails, the author gets a chance to retry any failed builds, or to
+push new commits to fix the failure.
+
+When the builds are retried and succeed on the second try, the merge request
+will automatically be merged after all. When the merge request is updated with
+new commits, the automatic merge is automatically canceled to allow the new
+changes to be reviewed.
+
+## Only allow merge requests to be merged if the build succeeds
+
+> **Note:**
+You need to have builds configured to enable this feature.
+
+You can prevent merge requests from being merged if their build did not succeed.
+
+Navigate to your project's settings page, select the
+**Only allow merge requests to be merged if the build succeeds** check box and
+hit **Save** for the changes to take effect.
+
+![Only allow merge if build succeeds settings](img/merge_when_build_succeeds_only_if_succeeds_settings.png)
+
+From now on, every time the build fails you will not be able to merge the merge
+request from the UI, until you make the build pass.

+# Merge requests versions
+
+> Will be [introduced][ce-5467] in GitLab 8.12.
+
+Every time you push to a branch that is tied to a merge request, a new version
+of merge request diff is created. When you visit a merge request that contains
+more than one pushes, you can select and compare the versions of those merge
+request diffs.
+
+![Merge Request Versions](img/versions.png)
+
+By default, the latest version of changes is shown. However, you
+can select an older one from version dropdown.
+
+![Merge Request Versions](img/versions-dropdown.png)
+
+You can also compare the merge request version with older one to see what is
+changed since then.
+
+![Merge Request Versions](img/versions-compare.png)
+
+Please note that comments are disabled while viewing outdated merge versions
+or comparing to versions other than base.
+
+---
+
+>**Note:**
+Merge request versions are based on push not on commit. So, if you pushed 5
+commits in a single push, it will be a single option in the dropdown. If you
+pushed 5 times, that will count for 5 options.

+# New CI build permissions model
+
+> Introduced in GitLab 8.12.
+
+GitLab 8.12 has a completely redesigned [build permissions] system. You can find
+all discussion and all our concerns when choosing the current approach in issue
+[#18994](https://gitlab.com/gitlab-org/gitlab-ce/issues/18994).
+
+---
+
+Builds permissions should be tightly integrated with the permissions of a user
+who is triggering a build.
+
+The reasons to do it like that are:
+
+- We already have a permissions system in place: group and project membership
+  of users.
+- We already fully know who is triggering a build (using `git push`, using the
+  web UI, executing triggers).
+- We already know what user is allowed to do.
+- We use the user permissions for builds that are triggered by the user.
+- It opens a lot of possibilities to further enforce user permissions, like
+  allowing only specific users to access runners or use secure variables and
+  environments.
+- It is simple and convenient that your build can access everything that you
+  as a user have access to.
+- Short living unique tokens are now used, granting access for time of the build
+  and maximizing security.
+
+With the new behavior, any build that is triggered by the user, is also marked
+with their permissions. When a user does a `git push` or changes files through
+the web UI, a new pipeline will be usually created. This pipeline will be marked
+as created be the pusher (local push or via the UI) and any build created in this
+pipeline will have the permissions of the pusher.
+
+This allows us to make it really easy to evaluate the access for all projects
+that have Git submodules or are using container images that the pusher would
+have access too. **The permission is granted only for time that build is running.
+The access is revoked after the build is finished.**
+
+## Types of users
+
+It is important to note that we have a few types of users:
+
+- **Administrators**: CI builds created by Administrators will not have access
+  to all GitLab projects, but only to projects and container images of projects
+  that the administrator is a member of.That means that if a project is either
+  public or internal users have access anyway, but if a project is private, the
+  Administrator will have to be a member of it in order to have access to it
+  via another project's build.
+
+- **External users**: CI builds created by [external users][ext] will have
+  access only to projects to which user has at least reporter access. This
+  rules out accessing all internal projects by default,
+
+This allows us to make the CI and permission system more trustworthy.
+Let's consider the following scenario:
+
+1. You are an employee of a company. Your company has a number of internal tools
+   hosted in private repositories and you have multiple CI builds that make use
+   of these repositories.
+
+2. You invite a new [external user][ext]. CI builds created by that user do not
+   have access to internal repositories, because the user also doesn't have the
+   access from within GitLab. You as an employee have to grant explicit access
+   for this user. This allows us to prevent from accidental data leakage.
+
+## Build token
+
+A unique build token is generated for each build and it allows the user to
+access all projects that would be normally accessible to the user creating that
+build.
+
+We try to make sure that this token doesn't leak by:
+
+1. Securing all API endpoints to not expose the build token.
+1. Masking the build token from build logs.
+1. Allowing to use the build token **only** when build is running.
+
+However, this brings a question about the Runners security. To make sure that
+this token doesn't leak, you should also make sure that you configure
+your Runners in the most possible secure way, by avoiding the following:
+
+1. Any usage of Docker's `privileged` mode is risky if the machines are re-used.
+1. Using the `shell` executor since builds run on the same machine.
+
+By using an insecure GitLab Runner configuration, you allow the rogue developers
+to steal the tokens of other builds.
+
+## Debugging problems
+
+With the new permission model in place, there may be times that your build will
+fail. This is most likely because your project tries to access other project's
+sources, and you don't have the appropriate permissions. In the build log look
+for information about 403 or forbidden access messages
+
+As an Administrator, you can verify that the user is a member of the group or
+project they're trying to have access to, and you can impersonate the user to
+retry the failing build in order to verify that everything is correct.
+
+## Build triggers
+
+[Build triggers][triggers] do not support the new permission model.
+They continue to use the old authentication mechanism where the CI build
+can access only its own sources. We plan to remove that limitation in one of
+the upcoming releases.
+
+## Before GitLab 8.12
+
+In versions before GitLab 8.12, all CI builds would use the CI Runner's token
+to checkout project sources.
+
+The project's Runner's token was a token that you could find under the
+project's **Settings > CI/CD Pipelines** and was limited to access only that
+project.
+It could be used for registering new specific Runners assigned to the project
+and to checkout project sources.
+It could also be used with the GitLab Container Registry for that project,
+allowing pulling and pushing Docker images from within the CI build.
+
+---
+
+GitLab would create a special checkout URL like:
+
+```
+https://gitlab-ci-token:<project-runners-token>/gitlab.com/gitlab-org/gitlab-ce.git
+```
+
+And then the users could also use it in their CI builds all Docker related
+commands to interact with GitLab Container Registry. For example:
+
+```
+docker login -u gitlab-ci-token -p $CI_BUILD_TOKEN registry.gitlab.com
+```
+
+Using single token had multiple security implications:
+
+- The token would be readable to anyone who had developer access to a project
+  that could run CI builds, allowing the developer to register any specific
+  Runner for that project.
+- The token would allow to access only the project's sources, forbidding from
+  accessing any other projects.
+- The token was not expiring and was multi-purpose: used for checking out sources,
+  for registering specific runners and for accessing a project's container
+  registry with read-write permissions.
+
+All the above led to a new permission model for builds that was introduced
+with GitLab 8.12.
+
+## Making use of the new CI build permissions model
+
+With the new build permission model, there is now an easy way to access all
+dependent source code in a project. That way, we can:
+
+1. Access a project's Git submodules
+1. Access private container images
+1. Access project's and submodule LFS objects
+
+Let's see how that works with Git submodules and private Docker images hosted on
+the container registry.
+
+## Git submodules
+
+>
+It often happens that while working on one project, you need to use another
+project from within it; perhaps it’s a library that a third party developed or
+you’re developing a project separately and are using it in multiple parent
+projects.
+A common issue arises in these scenarios: you want to be able to treat the two
+projects as separate yet still be able to use one from within the other.
+>
+_Excerpt from the [Git website][git-scm] about submodules._
+
+If dealing with submodules, your project will probably have a file named
+`.gitmodules`. And this is how it usually looks like:
+
+```
+[submodule "tools"]
+	path = tools
+	url = git@gitlab.com/group/tools.git
+```
+
+> **Note:**
+If you are **not** using GitLab 8.12 or higher, you would need to work your way
+around this issue in order to access the sources of `gitlab.com/group/tools`
+(e.g., use [SSH keys](../ssh_keys/README.md)).
+>
+With GitLab 8.12 onward, your permissions are used to evaluate what a CI build
+can access. More information about how this system works can be found in the
+[Build permissions model](../../user/permissions.md#builds-permissions).
+
+To make use of the new changes, you have to update your `.gitmodules` file to
+use a relative URL.
+
+Let's consider the following example:
+
+1. Your project is located at `https://gitlab.com/secret-group/my-project`.
+1. To checkout your sources you usually use an SSH address like
+   `git@gitlab.com:secret-group/my-project.git`.
+1. Your project depends on `https://gitlab.com/group/tools`.
+1. You have the `.gitmodules` file with above content.
+
+Since Git allows the usage of relative URLs for your `.gitmodules` configuration,
+this easily allows you to use HTTP for cloning all your CI builds and SSH
+for all your local checkouts.
+
+For example, if you change the `url` of your `tools` dependency, from
+`git@gitlab.com/group/tools.git` to `../../group/tools.git`, this will instruct
+Git to automatically deduce the URL that should be used when cloning sources.
+Whether you use HTTP or SSH, Git will use that same channel and it will allow
+to make all your CI builds use HTTPS (because GitLab CI uses HTTPS for cloning
+your sources), and all your local clones will continue using SSH.
+
+Given the above explanation, your `.gitmodules` file should eventually look
+like this:
+
+```
+[submodule "tools"]
+	path = tools
+	url = ../../group/tools.git
+```
+
+However, you have to explicitly tell GitLab CI to clone your submodules as this
+is not done automatically. You can achieve that by adding a `before_script`
+section to your `.gitlab-ci.yml`:
+
+```
+before_script:
+  - git submodule update --init --recursive
+
+test:
+  script:
+    - run-my-tests
+```
+
+This will make GitLab CI initialize (fetch) and update (checkout) all your
+submodules recursively.
+
+In case your environment or your Docker image doesn't have Git installed,
+you have to either ask your Administrator or install the missing dependency
+yourself:
+
+```
+# Debian / Ubuntu
+before_script:
+  - apt-get update -y
+  - apt-get install -y git-core
+  - git submodule update --init --recursive
+
+# CentOS / RedHat
+before_script:
+  - yum install git
+  - git submodule update --init --recursive
+
+# Alpine
+before_script:
+  - apk add -U git
+  - git submodule update --init --recursive
+```
+
+### Container Registry
+
+With the update permission model we also extended the support for accessing
+Container Registries for private projects.
+
+> **Note:**
+As GitLab Runner 1.6 doesn't yet incorporate the introduced changes for
+permissions, this makes the `image:` directive to not work with private projects
+automatically. The manual configuration by an Administrator is required to use
+private images. We plan to remove that limitation in one of the upcoming releases.
+
+Your builds can access all container images that you would normally have access
+to. The only implication is that you can push to the Container Registry of the
+project for which the build is triggered.
+
+This is how an example usage can look like:
+
+```
+test:
+  script:
+    - docker login -u gitlab-ci-token -p $CI_BUILD_TOKEN $CI_REGISTRY
+    - docker pull $CI_REGISTRY/group/other-project:latest
+    - docker run $CI_REGISTRY/group/other-project:latest
+```

+# GitLab Web Editor
+
+Sometimes it's easier to make quick changes directly from the GitLab interface
+than to clone the project and use the Git command line tool. In this feature
+highlight we look at how you can create a new file, directory, branch or
+tag from the file browser. All of these actions are available from a single
+dropdown menu.
+
+## Create a file
+
+From a project's files page, click the '+' button to the right of the branch selector.
+Choose **New file** from the dropdown.
+
+![New file dropdown menu](img/web_editor_new_file_dropdown.png)
+
+---
+
+Enter a file name in the **File name** box. Then, add file content in the editor
+area. Add a descriptive commit message and choose a branch. The branch field
+will default to the branch you were viewing in the file browser. If you enter
+a new branch name, a checkbox will appear allowing you to start a new merge
+request after you commit the changes.
+
+When you are satisfied with your new file, click **Commit Changes** at the bottom.
+
+![Create file editor](img/web_editor_new_file_editor.png)
+
+### Template dropdowns
+
+When starting a new project, there are some common files which the new project
+might need too. Therefore a message will be displayed by GitLab to make this
+easy for you.
+
+![First file for your project](img/web_editor_template_dropdown_first_file.png)
+
+When clicking on either `LICENSE` or `.gitignore`, a dropdown will be displayed
+to provide you with a template which might be suitable for your project.
+
+![MIT license selected](img/web_editor_template_dropdown_mit_license.png)
+
+The license, changelog, contribution guide, or `.gitlab-ci.yml` file could also
+be added through a button on the project page. In the example below the license
+has already been created, which creates a link to the license itself.
+
+![New file button](img/web_editor_template_dropdown_buttons.png)
+
+>**Note:**
+The **Set up CI** button will not appear on an empty repository. You have to at
+least add a file in order for the button to show up.
+
+## Upload a file
+
+The ability to create a file is great when the content is text. However, this
+doesn't work well for binary data such as images, PDFs or other file types. In
+this case you need to upload a file.
+
+From a project's files page, click the '+' button to the right of the branch
+selector. Choose **Upload file** from the dropdown.
+
+![Upload file dropdown menu](img/web_editor_upload_file_dropdown.png)
+
+---
+
+Once the upload dialog pops up there are two ways to upload your file. Either
+drag and drop a file on the pop up or use the **click to upload** link. A file
+preview will appear once you have selected a file to upload.
+
+Enter a commit message, choose a branch, and click **Upload file** when you are
+ready.
+
+![Upload file dialog](img/web_editor_upload_file_dialog.png)
+
+## Create a directory
+
+To keep files in the repository organized it is often helpful to create a new
+directory.
+
+From a project's files page, click the '+' button to the right of the branch selector.
+Choose **New directory** from the dropdown.
+
+![New directory dropdown](img/web_editor_new_directory_dropdown.png)
+
+---
+
+In the new directory dialog enter a directory name, a commit message and choose
+the target branch. Click **Create directory** to finish.
+
+![New directory dialog](img/web_editor_new_directory_dialog.png)
+
+## Create a new branch
+
+There are multiple ways to create a branch from GitLab's web interface.
+
+### Create a new branch from an issue
+
+> [Introduced][ce-2808] in GitLab 8.6.
+
+In case your development workflow dictates to have an issue for every merge
+request, you can quickly create a branch right on the issue page which will be
+tied with the issue itself. You can see a **New Branch** button after the issue
+description, unless there is already a branch with the same name or a referenced
+merge request.
+
+![New Branch Button](img/new_branch_from_issue.png)
+
+Once you click it, a new branch will be created that diverges from the default
+branch of your project, by default `master`. The branch name will be based on
+the title of the issue and as suffix it will have its ID. Thus, the example
+screenshot above will yield a branch named
+`2-et-cum-et-sed-expedita-repellat-consequatur-ut-assumenda-numquam-rerum`.
+
+After the branch is created, you can edit files in the repository to fix
+the issue. When a merge request is created based on the newly created branch,
+the description field will automatically display the [issue closing pattern]
+`Closes #ID`, where `ID` the ID of the issue. This will close the issue once the
+merge request is merged.
+
+### Create a new branch from a project's dashboard
+
+If you want to make changes to several files before creating a new merge
+request, you can create a new branch up front. From a project's files page,
+choose **New branch** from the dropdown.
+
+![New branch dropdown](img/web_editor_new_branch_dropdown.png)
+
+---
+
+Enter a new **Branch name**. Optionally, change the **Create from** field
+to choose which branch, tag or commit SHA this new branch will originate from.
+This field will autocomplete if you start typing an existing branch or tag.
+Click **Create branch** and you will be returned to the file browser on this new
+branch.
+
+![New branch page](img/web_editor_new_branch_page.png)
+
+---
+
+You can now make changes to any files, as needed. When you're ready to merge
+the changes back to master you can use the widget at the top of the screen.
+This widget only appears for a period of time after you create the branch or
+modify files.
+
+![New push widget](img/web_editor_new_push_widget.png)
+
+## Create a new tag
+
+Tags are useful for marking major milestones such as production releases,
+release candidates, and more. You can create a tag from a branch or a commit
+SHA. From a project's files page, choose **New tag** from the dropdown.
+
+![New tag dropdown](img/web_editor_new_tag_dropdown.png)
+
+---
+
+Give the tag a name such as `v1.0.0`. Choose the branch or SHA from which you
+would like to create this new tag. You can optionally add a message and
+release notes. The release notes section supports markdown format and you can
+also upload an attachment. Click **Create tag** and you will be taken to the tag
+list page.
+
+![New tag page](img/web_editor_new_tag_page.png)
+
+## Tips
+
+When creating or uploading a new file, or creating a new directory, you can
+trigger a new merge request rather than committing directly to master. Enter
+a new branch name in the **Target branch** field. You will notice a checkbox
+appear that is labeled **Start a new merge request with these changes**. After

-# Authorization for Merge requests
-
-There are two main ways to have a merge request flow with GitLab: working with protected branches in a single repository, or working with forks of an authoritative project.
-
-## Protected branch flow
-
-With the protected branch flow everybody works within the same GitLab project.
-
-The project maintainers get Master access and the regular developers get Developer access.
-
-The maintainers mark the authoritative branches as 'Protected'.
-
-The developers push feature branches to the project and create merge requests to have their feature branches reviewed and merged into one of the protected branches.
-
-Only users with Master access can merge changes into a protected branch.
-
-### Advantages
-
-- fewer projects means less clutter
-- developers need to consider only one remote repository
-
-### Disadvantages
-
-- manual setup of protected branch required for each new project
-
-## Forking workflow
-
-With the forking workflow the maintainers get Master access and the regular developers get Reporter access to the authoritative repository, which prohibits them from pushing any changes to it.
-
-Developers create forks of the authoritative project and push their feature branches to their own forks.
-
-To get their changes into master they need to create a merge request across forks.
-
-### Advantages
-
-- in an appropriately configured GitLab group, new projects automatically get the required access restrictions for regular developers: fewer manual steps to configure authorization for new projects
-
-### Disadvantages
-
-- the project need to keep their forks up to date, which requires more advanced Git skills (managing multiple remotes)

+## How it works
 
-With GitLab 8.7+, references to pull requests and issues are preserved.
+When issues/pull requests are being imported, the GitHub importer tries to find
+the GitHub author/assignee in GitLab's database using the GitHub ID. For this
+to work, the GitHub author/assignee should have signed in beforehand in GitLab
+and [**associated their GitHub account**][social sign-in]. If the user is not
+found in GitLab's database, the project creator (most of the times the current
+user that started the import process) is set as the author, but a reference on
+the issue about the original GitHub author is kept.
 
-The importer page is visible when you [create a new project][new-project].
-Click on the **GitHub** link and, if you are logged in via the GitHub
-integration, you will be redirected to GitHub for permission to access your
-projects. After accepting, you'll be automatically redirected to the importer.
+The importer will create any new namespaces (groups) if they don't exist or in
+the case the namespace is taken, the repository will be imported under the user's
+namespace that started the import process.
 
-If you are not using the GitHub integration, you can still perform a one-off
-authorization with GitHub to access your projects.
+## Importing your GitHub repositories
 
-Alternatively, you can also enter a GitHub Personal Access Token. Once you enter
-your token, you'll be taken to the importer.
+The importer page is visible when you create a new project.

----
+Click on the **GitHub** link and the import authorization process will start.
+There are two ways to authorize access to your GitHub repositories:
 
-While at the GitHub importer page, you can see the import statuses of your
-GitHub projects. Those that are being imported will show a _started_ status,
-those already imported will be green, whereas those that are not yet imported

+
+### Authorize access to your repositories using the GitHub integration
+
+If the [GitHub integration][gh-import] is enabled by your GitLab administrator,
+you can use it instead of the personal access token.
+
+1. First you may want to connect your GitHub account to GitLab in order for
+   the username mapping to be correct. Follow the [social sign-in] documentation
+   on how to do so.
+1. Once you connect GitHub, click the **List your GitHub repositories** button
+   and you will be redirected to GitHub for permission to access your projects.
+1. After accepting, you'll be automatically redirected to the importer.
+
+You can now go on and [select which repositories to import](#select-which-repositories-to-import).

+For a proper author/assignee mapping for issues and pull requests, the

+[personal access token][gh-token]. If the GitHub integration is enabled by your
+GitLab administrator, it should be the preferred method to import your repositories.
+Read more in the [How it works](#how-it-works) section.
+
+If you are not using the GitHub integration, you can still perform a one-off
+authorization with GitHub to grant GitLab access your repositories:
+
+1. Go to <https://github.com/settings/tokens/new>.
+1. Enter a token description.
+1. Check the `repo` scope.
+1. Click **Generate token**.
+1. Copy the token hash.
+1. Go back to GitLab and provide the token to the GitHub importer.
+1. Hit the **List your GitHub repositories** button and wait while GitLab reads
+   your repositories' information. Once done, you'll be taken to the importer
+   page to select the repositories to import.
+
+### Select which repositories to import
+
+After you've authorized access to your GitHub repositories, you will be
+redirected to the GitHub importer page.
+
+From there, you can see the import statuses of your GitHub repositories.

-When the build succeeds, the merge request will automatically be merged. When the build fails, the author gets a chance to retry any failed builds, or to push new commits to fix the failure.
-
-When the builds are retried and succeed on the second try, the merge request will automatically be merged after all. When the merge request is updated with new commits, the automatic merge is automatically canceled to allow the new changes to be reviewed.

-# Reverting changes
-
-> [Introduced][ce-1990] in GitLab 8.5.
-
----
-
-GitLab implements Git's powerful feature to [revert any commit][git-revert]
-with introducing a **Revert** button in Merge Requests and commit details.
-
-## Reverting a Merge Request
-
-_**Note:** The **Revert** button will only be available for Merge Requests
-created since GitLab 8.5. However, you can still revert a Merge Request
-by reverting the merge commit from the list of Commits page._
-
-After the Merge Request has been merged, a **Revert** button will be available
-to revert the changes introduced by that Merge Request:
-
-![Revert Merge Request](img/revert_changes_mr.png)
-
----
-
-You can revert the changes directly into the selected branch or you can opt to
-create a new Merge Request with the revert changes:
-
-![Revert Merge Request modal](img/revert_changes_mr_modal.png)
-
----
-
-After the Merge Request has been reverted, the **Revert** button will not be
-available anymore.
-
-## Reverting a Commit
-
-You can revert a Commit from the Commit details page:
-
-![Revert commit](img/revert_changes_commit.png)
-
----
-
-Similar to reverting a Merge Request, you can opt to revert the changes
-directly into the target branch or create a new Merge Request to revert the
-changes:
-
-![Revert commit modal](img/revert_changes_commit_modal.png)
-
----
-
-After the Commit has been reverted, the **Revert** button will not be available
-anymore.
-
-Please note that when reverting merge commits, the mainline will always be the
-first parent. If you want to use a different mainline then you need to do that
-from the command line.
-
-Here is a quick example to revert a merge commit using the second parent as the
-mainline:
-
-```bash
-git revert -m 2 7a39eb0
-```

-# GitLab Web Editor
-
-Sometimes it's easier to make quick changes directly from the GitLab interface
-than to clone the project and use the Git command line tool. In this feature
-highlight we look at how you can create a new file, directory, branch or
-tag from the file browser. All of these actions are available from a single
-dropdown menu.
-
-## Create a file
-
-From a project's files page, click the '+' button to the right of the branch selector.
-Choose **New file** from the dropdown.
-
-![New file dropdown menu](img/web_editor_new_file_dropdown.png)
-
----
-
-Enter a file name in the **File name** box. Then, add file content in the editor
-area. Add a descriptive commit message and choose a branch. The branch field
-will default to the branch you were viewing in the file browser. If you enter
-a new branch name, a checkbox will appear allowing you to start a new merge
-request after you commit the changes.
-
-When you are satisfied with your new file, click **Commit Changes** at the bottom.
-
-![Create file editor](img/web_editor_new_file_editor.png)
-
-## Upload a file
-
-The ability to create a file is great when the content is text. However, this
-doesn't work well for binary data such as images, PDFs or other file types. In
-this case you need to upload a file.
-
-From a project's files page, click the '+' button to the right of the branch
-selector. Choose **Upload file** from the dropdown.
-
-![Upload file dropdown menu](img/web_editor_upload_file_dropdown.png)
-
----
-
-Once the upload dialog pops up there are two ways to upload your file. Either
-drag and drop a file on the pop up or use the **click to upload** link. A file
-preview will appear once you have selected a file to upload.
-
-Enter a commit message, choose a branch, and click **Upload file** when you are
-ready.
-
-![Upload file dialog](img/web_editor_upload_file_dialog.png)
-
-## Create a directory
-
-To keep files in the repository organized it is often helpful to create a new
-directory.
-
-From a project's files page, click the '+' button to the right of the branch selector.
-Choose **New directory** from the dropdown.
-
-![New directory dropdown](img/web_editor_new_directory_dropdown.png)
-
----
-
-In the new directory dialog enter a directory name, a commit message and choose
-the target branch. Click **Create directory** to finish.
-
-![New directory dialog](img/web_editor_new_directory_dialog.png)
-
-## Create a new branch
-
-There are multiple ways to create a branch from GitLab's web interface.
-
-### Create a new branch from an issue
-
-> [Introduced][ce-2808] in GitLab 8.6.
-
-In case your development workflow dictates to have an issue for every merge
-request, you can quickly create a branch right on the issue page which will be
-tied with the issue itself. You can see a **New Branch** button after the issue
-description, unless there is already a branch with the same name or a referenced
-merge request.
-
-![New Branch Button](img/new_branch_from_issue.png)
-
-Once you click it, a new branch will be created that diverges from the default
-branch of your project, by default `master`. The branch name will be based on
-the title of the issue and as suffix it will have its ID. Thus, the example
-screenshot above will yield a branch named
-`2-et-cum-et-sed-expedita-repellat-consequatur-ut-assumenda-numquam-rerum`.
-
-After the branch is created, you can edit files in the repository to fix
-the issue. When a merge request is created based on the newly created branch,
-the description field will automatically display the [issue closing pattern]
-`Closes #ID`, where `ID` the ID of the issue. This will close the issue once the
-merge request is merged.
-
-### Create a new branch from a project's dashboard
-
-If you want to make changes to several files before creating a new merge
-request, you can create a new branch up front. From a project's files page,
-choose **New branch** from the dropdown.
-
-![New branch dropdown](img/web_editor_new_branch_dropdown.png)
-
----
-
-Enter a new **Branch name**. Optionally, change the **Create from** field
-to choose which branch, tag or commit SHA this new branch will originate from.
-This field will autocomplete if you start typing an existing branch or tag.
-Click **Create branch** and you will be returned to the file browser on this new
-branch.
-
-![New branch page](img/web_editor_new_branch_page.png)
-
----
-
-You can now make changes to any files, as needed. When you're ready to merge
-the changes back to master you can use the widget at the top of the screen.
-This widget only appears for a period of time after you create the branch or
-modify files.
-
-![New push widget](img/web_editor_new_push_widget.png)
-
-## Create a new tag
-
-Tags are useful for marking major milestones such as production releases,
-release candidates, and more. You can create a tag from a branch or a commit
-SHA. From a project's files page, choose **New tag** from the dropdown.
-
-![New tag dropdown](img/web_editor_new_tag_dropdown.png)
-
----
-
-Give the tag a name such as `v1.0.0`. Choose the branch or SHA from which you
-would like to create this new tag. You can optionally add a message and
-release notes. The release notes section supports markdown format and you can
-also upload an attachment. Click **Create tag** and you will be taken to the tag
-list page.
-
-![New tag page](img/web_editor_new_tag_page.png)
-
-## Tips
-
-When creating or uploading a new file, or creating a new directory, you can
-trigger a new merge request rather than committing directly to master. Enter
-a new branch name in the **Target branch** field. You will notice a checkbox
-appear that is labeled **Start a new merge request with these changes**. After
-you commit the changes you will be taken to a new merge request form.

+    # # Introduction - total running time
+    #
+    # The problem this module is trying to solve is finding the total running
+    # time amongst all the jobs, excluding retries and pending (queue) time.
+    # We could reduce this problem down to finding the union of periods.
+    #
+    # So each job would be represented as a `Period`, which consists of
+    # `Period#first` as when the job started and `Period#last` as when the
+    # job was finished. A simple example here would be:
+    #
+    # * A (1, 3)
+    # * B (2, 4)
+    # * C (6, 7)
+    #
+    # Here A begins from 1, and ends to 3. B begins from 2, and ends to 4.
+    # C begins from 6, and ends to 7. Visually it could be viewed as:
+    #
+    #     0  1  2  3  4  5  6  7
+    #        AAAAAAA
+    #           BBBBBBB
+    #                       CCCC
+    #
+    # The union of A, B, and C would be (1, 4) and (6, 7), therefore the
+    # total running time should be:
+    #
+    #     (4 - 1) + (7 - 6) => 4
+    #
+    # # The Algorithm
+    #
+    # The algorithm used here for union would be described as follow.
+    # First we make sure that all periods are sorted by `Period#first`.
+    # Then we try to merge periods by iterating through the first period
+    # to the last period. The goal would be merging all overlapped periods
+    # so that in the end all the periods are discrete. When all periods
+    # are discrete, we're free to just sum all the periods to get real
+    # running time.
+    #
+    # Here we begin from A, and compare it to B. We could find that
+    # before A ends, B already started. That is `B.first <= A.last`
+    # that is `2 <= 3` which means A and B are overlapping!
+    #
+    # When we found that two periods are overlapping, we would need to merge
+    # them into a new period and disregard the old periods. To make a new
+    # period, we take `A.first` as the new first because remember? we sorted
+    # them, so `A.first` must be smaller or equal to `B.first`. And we take
+    # `[A.last, B.last].max` as the new last because we want whoever ended
+    # later. This could be broken into two cases:
+    #
+    #     0  1  2  3  4
+    #        AAAAAAA
+    #           BBBBBBB
+    #
+    # Or:
+    #
+    #     0  1  2  3  4
+    #        AAAAAAAAAA
+    #           BBBB
+    #
+    # So that we need to take whoever ends later. Back to our example,
+    # after merging and discard A and B it could be visually viewed as:
+    #
+    #     0  1  2  3  4  5  6  7
+    #        DDDDDDDDDD
+    #                       CCCC
+    #
+    # Now we could go on and compare the newly created D and the old C.
+    # We could figure out that D and C are not overlapping by checking
+    # `C.first <= D.last` is `false`. Therefore we need to keep both C
+    # and D. The example would end here because there are no more jobs.
+    #
+    # After having the union of all periods, we just need to sum the length
+    # of all periods to get total time.
+    #
+    #     (4 - 1) + (7 - 6) => 4
+    #
+    # That is 4 is the answer in the example.

+//
 /*= provides tasklist:enabled */
-
-
 /*= provides tasklist:disabled */
-
-
 /*= provides tasklist:change */
-
-
 /*= provides tasklist:changed */
-
+//
+//
+// Enables Task List update behavior.
+//
+// ### Example Markup
+//
+//   <div class="js-task-list-container">
+//     <ul class="task-list">
+//       <li class="task-list-item">
+//         <input type="checkbox" class="js-task-list-item-checkbox" disabled />
+//         text
+//       </li>
+//     </ul>
+//     <form>
+//       <textarea class="js-task-list-field">- [ ] text</textarea>
+//     </form>
+//   </div>
+//
+// ### Specification
+//
+// TaskLists MUST be contained in a `(div).js-task-list-container`.
+//
+// TaskList Items SHOULD be an a list (`UL`/`OL`) element.
+//
+// Task list items MUST match `(input).task-list-item-checkbox` and MUST be
+// `disabled` by default.
+//
+// TaskLists MUST have a `(textarea).js-task-list-field` form element whose
+// `value` attribute is the source (Markdown) to be udpated. The source MUST
+// follow the syntax guidelines.
+//
+// TaskList updates trigger `tasklist:change` events. If the change is
+// successful, `tasklist:changed` is fired. The change can be canceled.
+//
+// jQuery is required.
+//
+// ### Methods
+//
+// `.taskList('enable')` or `.taskList()`
+//
+// Enables TaskList updates for the container.
+//
+// `.taskList('disable')`
+//
+// Disables TaskList updates for the container.
+//
+//# ### Events
+//
+// `tasklist:enabled`
+//
+// Fired when the TaskList is enabled.
+//
+// * **Synchronicity** Sync
+// * **Bubbles** Yes
+// * **Cancelable** No
+// * **Target** `.js-task-list-container`
+//
+// `tasklist:disabled`
+//
+// Fired when the TaskList is disabled.
+//
+// * **Synchronicity** Sync
+// * **Bubbles** Yes
+// * **Cancelable** No
+// * **Target** `.js-task-list-container`
+//
+// `tasklist:change`
+//
+// Fired before the TaskList item change takes affect.
+//
+// * **Synchronicity** Sync
+// * **Bubbles** Yes
+// * **Cancelable** Yes
+// * **Target** `.js-task-list-field`
+//
+// `tasklist:changed`
+//
+// Fired once the TaskList item change has taken affect.
+//
+// * **Synchronicity** Sync
+// * **Bubbles** Yes
+// * **Cancelable** No
+// * **Target** `.js-task-list-field`
+//
+// ### NOTE
+//
+// Task list checkboxes are rendered as disabled by default because rendered
+// user content is cached without regard for the viewer.
