+This often occurs when gitlab-shell attempts to request authorization via the

+1. Error accessing the repository (e.g., stale NFS handles)
+
+To diagnose this problem, try to reproduce the problem and then see if there

+# Database Debugging and Troubleshooting
+
+This section is to help give some copy-pasta you can use as a reference when you
+run into some head-banging database problems.
+
+An easy first step is to search for your error in Slack or google "GitLab <my error>".
+
+---
+
+Available `RAILS_ENV`
+
+ - `production` (generally not for your main GDK db, but you may need this for e.g. omnibus)
+ - `development` (this is your main GDK db)
+ - `test` (used for tests like rspec and spinach)
+
+
+## Nuke everything and start over
+
+If you just want to delete everything and start over with an empty DB (~1 minute):
+
+ - `bundle exec rake db:reset RAILS_ENV=development`
+
+If you just want to delete everything and start over with dummy data (~40 minutes). This also does `db:reset` and runs DB-specific migrations:
+
+ - `bundle exec rake dev:setup RAILS_ENV=development`
+
+If your test DB is giving you problems, it is safe to nuke it because it doesn't contain important data:
+
+ - `bundle exec rake db:reset RAILS_ENV=test`
+
+## Migration wrangling
+
+ - `bundle exec rake db:migrate RAILS_ENV=development`: Execute any pending migrations that you may have picked up from a MR
+ - `bundle exec rake db:migrate:status RAILS_ENV=development`: Check if all migrations are `up` or `down`
+ - `bundle exec rake db:migrate:down VERSION=20170926203418 RAILS_ENV=development`: Tear down a migration
+ - `bundle exec rake db:migrate:up VERSION=20170926203418 RAILS_ENV=development`: Setup a migration
+ - `bundle exec rake db:migrate:redo VERSION=20170926203418 RAILS_ENV=development`: Re-run a specific migration
+
+
+## Manually access the database
+
+Access the database via one of these commands (they all get you to the same place)
+
+```
+gdk psql -d gitlabhq_development
+bundle exec rails dbconsole RAILS_ENV=development
+bundle exec rails db RAILS_ENV=development
+```
+
+ - `\q`: Quit/exit
+ - `\dt`: List all tables
+ - `\d+ issues`: List columns for `issues` table
+ - `CREATE TABLE board_labels();`: Create a table called `board_labels`

+# Axios
+We use [axios][axios] to communicate with the server in Vue applications and most new code.
+
+In order to guarantee all defaults are set you *should not use `axios` directly*, you should import `axios` from `axios_utils`.
+
+## CSRF token
+All our request require a CSRF token.
+To guarantee this token is set, we are importing [axios][axios], setting the token, and exporting `axios` .
+
+This exported module should be used instead of directly using `axios` to ensure the token is set.
+
+## Usage
+```javascript
+  import axios from '~/lib/utils/axios_utils';
+
+  axios.get(url)
+    .then((response) => {
+      // `data` is the response that was provided by the server
+      const data = response.data;
+
+      // `headers` the headers that the server responded with
+      // All header names are lower cased
+      const paginationData = response.headers;
+    })
+    .catch(() => {
+      //handle the error
+    });
+```
+
+## Mock axios response on tests
+
+To help us mock the responses we need we use [axios-mock-adapter][axios-mock-adapter]
+
+
+```javascript
+  import axios from '~/lib/utils/axios_utils';
+  import MockAdapter from 'axios-mock-adapter';
+
+  let mock;
+  beforeEach(() => {
+    // This sets the mock adapter on the default instance
+    mock = new MockAdapter(axios);
+    // Mock any GET request to /users
+    // arguments for reply are (status, data, headers)
+    mock.onGet('/users').reply(200, {
+      users: [
+        { id: 1, name: 'John Smith' }
+      ]
+    });
+  });
+
+  afterEach(() => {
+    mock.reset();
+  });
+```
+
+### Mock poll requests on tests with axios
+
+Because polling function requires an header object, we need to always include an object as the third argument:
+
+```javascript
+  mock.onGet('/users').reply(200, { foo: 'bar' }, {});

+# Emojis
+
+GitLab supports native unicode emojis and fallsback to image-based emojis selectively
+when your platform does not support it.
+
+# How to update Emojis
+
+ 1. Update the `gemojione` gem
+ 1. Update `fixtures/emojis/index.json` from [Gemojione](https://github.com/jonathanwiesel/gemojione/blob/master/config/index.json).
+    In the future, we could grab the file directly from the gem.
+    We should probably make a PR on the Gemojione project to get access to
+    all emojis after being parsed or just a raw path to the `json` file itself.
+ 1. Ensure [`emoji-unicode-version`](https://www.npmjs.com/package/emoji-unicode-version)
+    is up to date with the latest version.
+ 1. Run `bundle exec rake gemojione:aliases`
+ 1. Run `bundle exec rake gemojione:digests`
+ 1. Run `bundle exec rake gemojione:sprite`
+ 1. Ensure new sprite sheets generated for 1x and 2x
+    - `app/assets/images/emoji.png`
+    - `app/assets/images/emoji@2x.png`
+ 1. Ensure you see new individual images copied into `app/assets/images/emoji/`
+ 1. Ensure you can see the new emojis and their aliases in the GFM Autocomplete
+ 1. Ensure you can see the new emojis and their aliases in the award emoji menu
+ 1. You might need to add new emoji unicode support checks and rules for platforms
+    that do not support a certain emoji and we need to fallback to an image.

-# Vue Resouce
-In Vue applications we use [vue-resource][vue-resource-repo] to communicate with the server.
-
-## HTTP Status Codes
-
-### `.json()`
-When making a request to the server, you will most likely need to access the body of the response.
-Use `.json()` to convert. Because `.json()` returns a Promise the follwoing structure should be used:
-
-  ```javascript
-  service.get('url')
-    .then(resp => resp.json())
-    .then((data) => {
-      this.store.storeData(data);
-    })
-    .catch(() => new Flash('Something went wrong'));
-  ```
-
-
-When using `Poll` (`app/assets/javascripts/lib/utils/poll.js`), the `successCallback` needs to handle `.json()` as a Promise:
-  ```javascript
-  successCallback: (response) => {
-    return response.json().then((data) => {
-      // handle the response
-    });
-  }
-  ```
-
-### 204
-Some endpoints - usually `delete` endpoints - return `204` as the success response.
-When handling `204 - No Content` responses, we cannot use `.json()` since it tries to parse the non-existant body content.
-
-When handling `204` responses, do not use `.json`, otherwise the promise will throw an error and will enter the `catch` statement:
-
-```javascript
-  Vue.http.delete('path')
-    .then(() => {
-      // success!
-    })
-    .catch(() => {
-      // handle error
-    })
-```
-
-## Headers
-Headers are being parsed into a plain object in an interceptor.
-In Vue-resource 1.x `headers` object was changed into an `Headers` object. In order to not change all old code, an interceptor was added.
-
-If you need to write a unit test that takes the headers in consideration, you need to include an interceptor to parse the headers after your test interceptor.
-You can see an example in `spec/javascripts/environments/environment_spec.js`:
-  ```javascript
-  import { headersInterceptor } from './helpers/vue_resource_helper';
-
-  beforeEach(() => {
-    Vue.http.interceptors.push(myInterceptor);
-    Vue.http.interceptors.push(headersInterceptor);
-  });
-
-  afterEach(() => {
-    Vue.http.interceptors = _.without(Vue.http.interceptors, myInterceptor);
-    Vue.http.interceptors = _.without(Vue.http.interceptors, headersInterceptor);
-  });
-  ```
-
-## CSRF token
-We use a Vue Resource interceptor to manage the CSRF token.
-`app/assets/javascripts/vue_shared/vue_resource_interceptor.js` holds all our common interceptors.
-Note: You don't need to load `app/assets/javascripts/vue_shared/vue_resource_interceptor.js`

+# Working with the GitHub importer
+
+In GitLab 10.2 a new version of the GitHub importer was introduced. This new
+importer performs its work in parallel using Sidekiq, greatly reducing the time
+necessary to import GitHub projects into a GitLab instance.
+
+The GitHub importer offers two different types of importers: a sequential
+importer and a parallel importer. The Rake task `import:github` uses the
+sequential importer, while everything else uses the parallel importer. The
+difference between these two importers is quite simple: the sequential importer
+does all work in a single thread, making it more useful for debugging purposes
+or Rake tasks. The parallel importer on the other hand uses Sidekiq.
+
+## Requirements
+
+* GitLab CE 10.2.0 or newer.
+* Sidekiq workers that process the `github_importer` and
+  `github_importer_advance_stage` queues (this is enabled by default).
+* Octokit (used for interacting with the GitHub API)
+
+## Code structure
+
+The importer's codebase is broken up into the following directories:
+
+* `lib/gitlab/github_import`: this directory contains most of the code such as
+  the classes used for importing resources.
+* `app/workers/gitlab/github_import`: this directory contains the Sidekiq
+  workers.
+* `app/workers/concerns/gitlab/github_import`: this directory contains a few
+  modules reused by the various Sidekiq workers.
+
+## Architecture overview
+
+When a GitHub project is imported we schedule and execute a job for the
+`RepositoryImportworker` worker as all other importers. However, unlike other
+importers we don't immediately perform the work necessary. Instead work is
+divided into separate stages, with each stage consisting out of a set of Sidekiq
+jobs that are executed. Between every stage a job is scheduled that periodically
+checks if all work of the current stage is completed, advancing the import
+process to the next stage when this is the case. The worker handling this is
+called `Gitlab::GithubImport::AdvanceStageWorker`.
+
+## Stages
+
+### 1. RepositoryImportWorker
+
+This worker will kick off the import process by simply scheduling a job for the
+next worker.
+
+### 2. Stage::ImportRepositoryWorker
+
+This worker will import the repository and wiki, scheduling the next stage when
+done.
+
+### 3. Stage::ImportBaseDataWorker
+
+This worker will import base data such as labels, milestones, and releases. This
+work is done in a single thread since it can be performed fast enough that we
+don't need to perform this work in parallel.
+
+### 4. Stage::ImportPullRequestsWorker
+
+This worker will import all pull requests. For every pull request a job for the
+`Gitlab::GithubImport::ImportPullRequestWorker` worker is scheduled.
+
+### 5. Stage::ImportIssuesAndDiffNotesWorker
+
+This worker will import all issues and pull request comments. For every issue we
+schedule a job for the `Gitlab::GithubImport::ImportIssueWorker` worker. For
+pull request comments we instead schedule jobs for the
+`Gitlab::GithubImport::DiffNoteImporter` worker.
+
+This worker processes both issues and diff notes in parallel so we don't need to
+schedule a separate stage and wait for the previous one to complete.
+
+Issues are imported separately from pull requests because only the "issues" API
+includes labels for both issue and pull requests. Importing issues and setting
+label links in the same worker removes the need for performing a separate crawl
+through the API data, reducing the number of API calls necessary to import a
+project.
+
+### 6. Stage::ImportNotesWorker
+
+This worker imports regular comments for both issues and pull requests. For
+every comment we schedule a job for the
+`Gitlab::GithubImport::ImportNoteWorker` worker.
+
+Regular comments have to be imported at the end since the GitHub API used
+returns comments for both issues and pull requests. This means we have to wait
+for all issues and pull requests to be imported before we can import regular
+comments.
+
+### 7. Stage::FinishImportWorker
+
+This worker will wrap up the import process by performing some housekeeping
+(such as flushing any caches) and by marking the import as completed.
+
+## Advancing stages
+
+Advancing stages is done in one of two ways:
+
+1. Scheduling the worker for the next stage directly.
+2. Scheduling a job for `Gitlab::GithubImport::AdvanceStageWorker` which will
+   advance the stage when all work of the current stage has been completed.
+
+The first approach should only be used by workers that perform all their work in
+a single thread, while `AdvanceStageWorker` should be used for everything else.
+
+The way `AdvanceStageWorker` works is fairly simple. When scheduling a job it
+will be given a project ID, a list of Redis keys, and the name of the next
+stage. The Redis keys (produced by `Gitlab::JobWaiter`) are used to check if the
+currently running stage has been completed or not. If the stage has not yet been
+completed `AdvanceStageWorker` will reschedule itself. Once a stage finishes
+`AdvanceStageworker` will refresh the import JID (more on this below) and
+schedule the worker of the next stage.
+
+To reduce the number of `AdvanceStageWorker` jobs scheduled this worker will
+briefly wait for jobs to complete before deciding what the next action should
+be. For small projects this may slow down the import process a bit, but it will
+also reduce pressure on the system as a whole.
+
+## Refreshing import JIDs
+
+GitLab includes a worker called `StuckImportJobsWorker` that will periodically
+run and mark project imports as failed if they have been running for more than
+15 hours. For GitHub projects this poses a bit of a problem: importing large
+projects could take several hours depending on how often we hit the GitHub rate
+limit (more on this below), but we don't want `StuckImportJobsWorker` to mark
+our import as failed because of this.
+
+To prevent this from happening we periodically refresh the expiration time of
+the import process. This works by storing the JID of the import job in the
+database, then refreshing this JID's TTL at various stages throughout the import
+process. This is done by calling `Project#refresh_import_jid_expiration`. By
+refreshing this TTL we can ensure our import does not get marked as failed so
+long we're still performing work.
+
+## GitHub rate limit
+
+GitHub has a rate limit of 5 000 API calls per hour. The number of requests
+necessary to import a project is largely dominated by the number of unique users
+involved in a project (e.g. issue authors). Other data such as issue pages
+and comments typically only requires a few dozen requests to import.  This is
+because we need the Email address of users in order to map them to GitLab users.
+
+We handle this by doing the following:
+
+1. Once we hit the rate limit all jobs will automatically reschedule themselves
+   in such a way that they are not executed until the rate limit has been reset.
+2. We cache the mapping of GitHub users to GitLab users in Redis.
+
+More information on user caching can be found below.
+
+## Caching user lookups
+
+When mapping GitHub users to GitLab users we need to (in the worst case)
+perform:
+
+1. One API call to get the user's Email address.
+2. Two database queries to see if a corresponding GitLab user exists. One query
+   will try to find the user based on the GitHub user ID, while the second query
+   is used to find the user using their GitHub Email address.
+
+Because this process is quite expensive we cache the result of these lookups in
+Redis. For every user looked up we store three keys:
+
+1. A Redis key mapping GitHub usernames to their Email addresses.
+2. A Redis key mapping a GitHub Email addresses to a GitLab user ID.
+3. A Redis key mapping a GitHub user ID to GitLab user ID.
+
+There are two types of lookups we cache:
+
+1. A positive lookup, meaning we found a GitLab user ID.
+2. A negative lookup, meaning we didn't find a GitLab user ID. Caching this
+   prevents us from performing the same work for users that we know don't exist
+   in our GitLab database.
+
+The expiration time of these keys is 24 hours. When retrieving the cache of a
+positive lookups we refresh the TTL automatically. The TTL of false lookups is
+never refreshed.
+
+Because of this caching layer it's possible newly registered GitLab accounts
+won't be linked to their corresponding GitHub accounts. This however will sort
+itself out once the cached keys expire.
+
+The user cache lookup is shared across projects. This means that the more
+projects get imported the fewer GitHub API calls will be needed.
+
+The code for this resides in:
+
+* `lib/gitlab/github_import/user_finder.rb`
+* `lib/gitlab/github_import/caching.rb`
+
+## Mapping labels and milestones
+
+To reduce pressure on the database we do not query it when setting labels and
+milestones on issues and merge requests. Instead we cache this data when we
+import labels and milestones, then we reuse this cache when assigning them to
+issues/merge requests. Similar to the user lookups these cache keys are expired
+automatically after 24 hours of not being used.
+
+Unlike the user lookup caches these label and milestone caches are scoped to the
+project that is being imported.
+
+The code for this resides in:
+
+* `lib/gitlab/github_import/label_finder.rb`
+* `lib/gitlab/github_import/milestone_finder.rb`
+* `lib/gitlab/github_import/caching.rb`

+values if absolutely necessary. There is a RuboCop cop that will fail if this
+method is used on some tables that are very large on GitLab.com, which would
+cause other issues.
+
+## Updating an existing column
+
+To update an existing column to a particular value, you can use
+`update_column_in_batches` (`add_column_with_default` uses this internally to
+fill in the default value). This will split the updates into batches, so we
+don't update too many rows at in a single statement.
+
+This updates the column `foo` in the `projects` table to 10, where `some_column`
+is `'hello'`:
+
+```ruby
+update_column_in_batches(:projects, :foo, 10) do |table, query|
+  query.where(table[:some_column].eq('hello'))
+end
+```
+
+To perform a computed update, the value can be wrapped in `Arel.sql`, so Arel
+treats it as an SQL literal. The below example is the same as the one above, but
+the value is set to the product of the `bar` and `baz` columns:
+
+```ruby
+update_value = Arel.sql('bar * baz')
+
+update_column_in_batches(:projects, :foo, update_value) do |table, query|
+  query.where(table[:some_column].eq('hello'))
+end
+```
+
+Like `add_column_with_default`, there is a RuboCop cop to detect usage of this
+on large tables. In the case of `update_column_in_batches`, it may be acceptable
+to run on a large table, as long as it is only updating a small subset of the
+rows in the table, but do not ignore that without validating on the GitLab.com
+staging environment - or asking someone else to do so for you - beforehand.

+## Dialog modals
+
+Dialog modals are only used for having a conversation and confirmation with the user. The user is not able to access the features on the main page until closing the modal.
+
+### Usage
+
+* When the action is irreversible, dialog modals provide the details and confirm with the user before they take an advanced action.
+* When the action will affect privacy or authorization, dialog modals provide advanced information and confirm with the user.
+
+### Style
+
+* Dialog modals contain the header, body, and actions.
+  * **Header(1):** The header title is a question instead of a descriptive phrase.
+  * **Body(2):** The content in body should never be ambiguous and unclear. It provides specific information.
+  * **Actions(3):** Contains a affirmative action, a dismissive action, and an extra action. The order of actions from left to right: Dismissive action → Extra action → Affirmative action
+* Confirmations regarding labels should keep labeling styling.
+* References to commits, branches, and tags should be **monospaced**.

-#### Motivations
+### Motivations
 Nazim works for a software development company which currently hires around 80 people. When Nazim first joined the company, the engineering team were using Subversion (SVN) as their primary form of source control. However, Nazim felt SVN was not flexible enough to work with many feature branches and noticed that developers with less experience of source control struggled with the central-repository nature of SVN. Armed with a wishlist of features, Nazim began comparing source control tools. A search for “self-hosted Git server repository management� returned GitLab. In his own words, Nazim explains why he wanted the engineering team to start using GitLab:

-#### Frustrations
-##### Adoption to GitLab has been slow
+### Frustrations
+#### Adoption to GitLab has been slow
 Not only has the engineering team had to get to grips with Git, they’ve also had to adapt to using GitLab. Due to lack of training and existing skills in other tools, the full feature set of GitLab CE is not being utilised. Nazim sold GitLab to his manager as an ‘all in one’ tool which would replace multiple tools used within the company, thus saving costs. Nazim hasn’t had the time to integrate the legacy tools to GitLab and he’s struggling to convince his peers to change their habits.
 
-##### Missing Features
+#### Missing Features
 Nazim’s company want GitLab to be able to do everything. There isn’t a large budget for software, so they’re selective about what tools are implemented. It needs to add real value to the company. In order for GitLab to be widely adopted and to meet the requirements of different roles within the company, it needs a host of features. When an individual within Nazim’s company wants to know if GitLab has a specific feature or does a particular thing, Nazim is the person to ask. He becomes the point of contact to investigate, build or sometimes just raise the feature request. Nazim gets frustrated when GitLab isn’t able to do what he or his colleagues need it to do.
 
-##### Regressions and bugs
+#### Regressions and bugs
 Nazim often has to calm down his colleagues, when a release contains regressions or new bugs. As he puts it “every new version adds something awesome, but breaks something�. He feels that “old issues for "minor" annoyances get quickly buried in the mass of open issues and linger for a very long time. More generally, I have the feeling that GitLab focus on adding new functionalities, but overlook a bunch of annoying minor regressions or introduced bugs.� Due to limited resource and expertise within the team, not only is it difficult to remain up-to-date with the frequent release cycle, it’s also counterproductive to fix workflows every month.
 
-##### Uses too much RAM and CPU
+#### Uses too much RAM and CPU

 “Memory usages mean that if we host it from a cloud based host like AWS, we spend almost as much on the instance as what we would pay GitHub�
 >
 
-##### UI/UX
+#### UI/UX
 GitLab’s interface initially attracted Nazim when he was comparing version control software. He thought it would help his less technical colleagues to adapt to using Git and perhaps, GitLab could be rolled out to other areas of the business, beyond engineering. However, using GitLab’s interface daily has left him frustrated at the lack of personalisation / control over his user experience. He’s also regularly lost in a maze of navigation. Whilst he acknowledges that GitLab listens to its users and that the interface is improving, he becomes annoyed when the changes are too progressive. “Too frequent UI changes. Most of them tend to turn out great after a few cycles of fixes, but the frequency is still far too high for me to feel comfortable to always stay on the current release.�
 
-#### Goals 
+### Goals
 * To convince his colleagues to fully adopt GitLab CE, thus improving workflow and collaboration.
 * To use a feature rich version control platform that covers all stages of the development lifecycle, in order to reduce dependencies on other tools.
 * To use an intuitive and stable product, so he can spend more time on his core job responsibilities and less time bug-fixing, guiding colleagues, etc.

+### Frustrations
+#### Third Party Integration
 Some of GitLab EE’s features are too basic, in particular, issues boards which do not have the level of reporting that James and his team need. Subsequently, they still need to use GitLab EE in conjunction with other tools, such as JIRA. Whilst James feels it isn’t essential for GitLab to meet all his needs (his company are happy for him to use, and pay for, multiple tools), he sometimes isn’t sure what is/isn’t possible with plugins and what level of custom development he and his team will need to do.
 
-##### UX/UI
+#### UX/UI
 James and his team use CI quite heavily for several projects. Whilst they’ve welcomed improvements to the builds and pipelines interface, they still have some difficulty following build process on the different tabs under Pipelines. Some confusion has arisen from not knowing where to find different pieces of information or how to get to the next stages logs from the current stage’s log output screen. They feel more intuitive linking and flow may alleviate the problem. Generally, they feel GitLab’s navigation needs to reviewed and optimised.

 “There is no granular control over user or group permissions. The permissions for a project are too tightly coupled to the permissions for Gitlab CI/build pipelines.�

 * To be able to integrate third party tools easily with GitLab EE and to create custom integrations and patches where needed.
 * To use GitLab EE primarily for code hosting, merge requests, continuous integration and issue management. James and his team want to be able to understand and use these particular features easily.
 * To able to share one instance of GitLab EE with multiple teams across the business. Advanced user management, the ability to separate permissions on different parts of the source code, etc are important to James.

-#### Motivations
+### Motivations
 Karolina has been using GitLab.com for around a year. She roughly spends 8 hours every week programming, of that, 2 hours is spent contributing to open source projects. Karolina contributes to open source projects to gain programming experience and to give back to the community. She likes GitLab.com for its free private repositories and range of features which provide her with everything she needs for her personal projects. Karolina is also a massive fan of GitLab’s values and the fact that it isn’t a “behemoth of a company�.  She explains that “displaying every single thing (doc, culture, assumptions, development...) in the open gives me greater confidence to choose Gitlab personally and to recommend it at work.�  She’s also an avid reader of GitLab’s blog.
 
 Karolina works for a software development company which currently hires around 500 people. Karolina would love to use GitLab at work but the company has used GitHub Enterprise for a number of years. She describes management at her company as “old fashioned� and explains that it’s “less of a technical issue and more of a cultural issue� to convince upper management to move to GitLab. Karolina is also relatively new to the company so she’s apprehensive about pushing too hard to change version control platforms.

 Karolina wants to use GitLab at work but isn’t sure how to approach the subject with management. In her current role, she doesn’t feel that she has the authority to request GitLab.
 
-##### Performance

 GitLab.com is frequently slow and unavailable. Karolina has also heard that GitLab is a “memory hog�  which has deterred her from running GitLab on her own machine for just hobby / personal projects.
 
-##### UX/UI

 Karolina has an interest in UX and therefore has strong opinions about how GitLab should look and feel. She feels the interface is cluttered, “it has too many links/buttons� and the navigation “feels a bit weird sometimes. I get lost if I don’t pay attention.� As Karolina also enjoys contributing to open-source projects, it’s important to her that GitLab is well designed for public repositories, she doesn’t feel that GitLab currently achieves this.

+First Byte (sometimes referred to as time to first byte or [TTFB](https://en.wikipedia.org/wiki/Time_To_First_Byte)) measures the time between making a request and receiving the first byte of information in return. As a result, First Byte encompasses everything that is the backend as well as network transit issues. It differs from [_Speed Index_](#speed-index) mostly by frontend related issues which are included in Speed Index such as javascript loading, page rendering, and so on.

+# From 10.1 to 10.2
+
+Make sure you view this update guide from the tag (version) of GitLab you would
+like to install. In most cases this should be the highest numbered production
+tag (without rc in it). You can select the tag in the version dropdown at the
+top left corner of GitLab (below the menu bar).
+
+If the highest number stable branch is unclear please check the
+[GitLab Blog](https://about.gitlab.com/blog/archives.html) for installation
+guide links by version.
+
+### 1. Stop server
+
+```bash
+sudo service gitlab stop
+```
+
+### 2. Backup
+
+```bash
+cd /home/git/gitlab
+
+sudo -u git -H bundle exec rake gitlab:backup:create RAILS_ENV=production
+```
+
+### 3. Update Ruby
+
+NOTE: GitLab 9.0 and higher only support Ruby 2.3.x and dropped support for Ruby 2.1.x. Be
+sure to upgrade your interpreter if necessary.
+
+You can check which version you are running with `ruby -v`.
+
+Download and compile Ruby:
+
+```bash
+mkdir /tmp/ruby && cd /tmp/ruby
+curl --remote-name --progress https://cache.ruby-lang.org/pub/ruby/2.3/ruby-2.3.5.tar.gz
+echo '3247e217d6745c27ef23bdc77b6abdb4b57a118f  ruby-2.3.5.tar.gz' | shasum -c - && tar xzf ruby-2.3.5.tar.gz
+cd ruby-2.3.5
+./configure --disable-install-rdoc
+make
+sudo make install
+```
+
+Install Bundler:
+
+```bash
+sudo gem install bundler --no-ri --no-rdoc
+```
+
+### 4. Update Node
+
+GitLab now runs [webpack](http://webpack.js.org) to compile frontend assets and
+it has a minimum requirement of node v4.3.0.
+
+You can check which version you are running with `node -v`. If you are running
+a version older than `v4.3.0` you will need to update to a newer version.  You
+can find instructions to install from community maintained packages or compile
+from source at the nodejs.org website.
+
+<https://nodejs.org/en/download/>
+
+
+Since 8.17, GitLab requires the use of yarn `>= v0.17.0` to manage
+JavaScript dependencies.
+
+```bash
+curl --silent --show-error https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add -
+echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list
+sudo apt-get update
+sudo apt-get install yarn
+```
+
+More information can be found on the [yarn website](https://yarnpkg.com/en/docs/install).
+
+### 5. Update Go
+
+NOTE: GitLab 9.2 and higher only supports Go 1.8.3 and dropped support for Go
+1.5.x through 1.7.x. Be sure to upgrade your installation if necessary.
+
+You can check which version you are running with `go version`.
+
+Download and install Go:
+
+```bash
+# Remove former Go installation folder
+sudo rm -rf /usr/local/go
+
+curl --remote-name --progress https://storage.googleapis.com/golang/go1.8.3.linux-amd64.tar.gz
+echo '1862f4c3d3907e59b04a757cfda0ea7aa9ef39274af99a784f5be843c80c6772  go1.8.3.linux-amd64.tar.gz' | shasum -a256 -c - && \
+  sudo tar -C /usr/local -xzf go1.8.3.linux-amd64.tar.gz
+sudo ln -sf /usr/local/go/bin/{go,godoc,gofmt} /usr/local/bin/
+rm go1.8.3.linux-amd64.tar.gz
+```
+
+### 6. Get latest code
+
+```bash
+cd /home/git/gitlab
+
+sudo -u git -H git fetch --all
+sudo -u git -H git checkout -- db/schema.rb # local changes will be restored automatically
+sudo -u git -H git checkout -- locale
+```
+
+For GitLab Community Edition:
+
+```bash
+cd /home/git/gitlab
+
+sudo -u git -H git checkout 10-2-stable
+```
+
+OR
+
+For GitLab Enterprise Edition:
+
+```bash
+cd /home/git/gitlab
+
+sudo -u git -H git checkout 10-2-stable-ee
+```
+
+### 7. Update gitlab-shell
+
+```bash
+cd /home/git/gitlab-shell
+
+sudo -u git -H git fetch --all --tags
+sudo -u git -H git checkout v$(</home/git/gitlab/GITLAB_SHELL_VERSION)
+sudo -u git -H bin/compile
+```
+
+### 8. Update gitlab-workhorse
+
+Install and compile gitlab-workhorse. GitLab-Workhorse uses
+[GNU Make](https://www.gnu.org/software/make/).
+If you are not using Linux you may have to run `gmake` instead of
+`make` below.
+
+```bash
+cd /home/git/gitlab-workhorse
+
+sudo -u git -H git fetch --all --tags
+sudo -u git -H git checkout v$(</home/git/gitlab/GITLAB_WORKHORSE_VERSION)
+sudo -u git -H make
+```
+
+### 9. Update Gitaly
+
+#### New Gitaly configuration options required
+
+In order to function Gitaly needs some additional configuration information. Below we assume you installed Gitaly in `/home/git/gitaly` and GitLab Shell in `/home/git/gitlab-shell`.
+
+```shell
+echo '
+[gitaly-ruby]
+dir = "/home/git/gitaly/ruby"
+
+[gitlab-shell]
+dir = "/home/git/gitlab-shell"
+' | sudo -u git tee -a /home/git/gitaly/config.toml
+```
+
+#### Check Gitaly configuration
+
+Due to a bug in the `rake gitlab:gitaly:install` script your Gitaly
+configuration file may contain syntax errors. The block name
+`[[storages]]`, which may occur more than once in your `config.toml`
+file, should be `[[storage]]` instead.
+
+```shell
+sudo -u git -H sed -i.pre-10.1 's/\[\[storages\]\]/[[storage]]/' /home/git/gitaly/config.toml
+```
+
+#### Compile Gitaly
+
+```shell
+cd /home/git/gitaly
+sudo -u git -H git fetch --all --tags
+sudo -u git -H git checkout v$(</home/git/gitlab/GITALY_SERVER_VERSION)
+sudo -u git -H make
+```
+
+### 10. Update MySQL permissions
+
+If you are using MySQL you need to grant the GitLab user the necessary
+permissions on the database:
+
+```bash
+mysql -u root -p -e "GRANT TRIGGER ON \`gitlabhq_production\`.* TO 'git'@'localhost';"
+```
+
+If you use MySQL with replication, or just have MySQL configured with binary logging,
+you will need to also run the following on all of your MySQL servers:
+
+```bash
+mysql -u root -p -e "SET GLOBAL log_bin_trust_function_creators = 1;"
+```
+
+You can make this setting permanent by adding it to your `my.cnf`:
+
+```
+log_bin_trust_function_creators=1
+```
+
+### 11. Update configuration files
+
+#### New configuration options for `gitlab.yml`
+
+There might be configuration options available for [`gitlab.yml`][yaml]. View them with the command below and apply them manually to your current `gitlab.yml`:
+
+```sh
+cd /home/git/gitlab
+
+git diff origin/10-1-stable:config/gitlab.yml.example origin/10-2-stable:config/gitlab.yml.example
+```
+
+#### Nginx configuration
+
+Ensure you're still up-to-date with the latest NGINX configuration changes:
+
+```sh
+cd /home/git/gitlab
+
+# For HTTPS configurations
+git diff origin/10-1-stable:lib/support/nginx/gitlab-ssl origin/10-2-stable:lib/support/nginx/gitlab-ssl
+
+# For HTTP configurations
+git diff origin/10-1-stable:lib/support/nginx/gitlab origin/10-2-stable:lib/support/nginx/gitlab
+```
+
+If you are using Strict-Transport-Security in your installation to continue using it you must enable it in your Nginx
+configuration as GitLab application no longer handles setting it.
+
+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/10-2-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/10-2-stable/config/initializers/smtp_settings.rb.sample#L13
+
+#### Init script
+
+There might be new configuration options available for [`gitlab.default.example`][gl-example]. View them with the command below and apply them manually to your current `/etc/default/gitlab`:
+
+```sh
+cd /home/git/gitlab
+
+git diff origin/10-1-stable:lib/support/init.d/gitlab.default.example origin/10-2-stable:lib/support/init.d/gitlab.default.example
+```
+
+Ensure you're still up-to-date with the latest init script changes:
+
+```bash
+cd /home/git/gitlab
+
+sudo cp lib/support/init.d/gitlab /etc/init.d/gitlab
+```
+
+For Ubuntu 16.04.1 LTS:
+
+```bash
+sudo systemctl daemon-reload
+```
+
+### 12. 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
+
+# Compile GetText PO files
+
+sudo -u git -H bundle exec rake gettext:compile RAILS_ENV=production
+
+# Update node dependencies and recompile assets
+sudo -u git -H bundle exec rake yarn:install gitlab:assets:clean gitlab:assets:compile RAILS_ENV=production NODE_ENV=production
+
+# Clean up cache
+sudo -u git -H bundle exec rake cache:clear RAILS_ENV=production
+```
+
+**MySQL installations**: Run through the `MySQL strings limits` and `Tables and data conversion to utf8mb4` [tasks](../install/database_mysql.md).
+
+### 13. Start application
+
+```bash
+sudo service gitlab start
+sudo service nginx restart
+```
+
+### 14. Check application status
+
+Check if GitLab and its environment are configured correctly:
+
+```bash
+cd /home/git/gitlab
+
+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:
+
+```bash
+cd /home/git/gitlab
+
+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 (10.0)
+
+### 1. Revert the code to the previous version
+
+Follow the [upgrade guide from 9.5 to 10.0](9.5-to-10.0.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.

+
+| Application | GitLab version | Description |
+| ----------- | :------------: | ----------- |
+| [Helm Tiller](https://docs.helm.sh/) | 10.2+ | Helm is a package manager for Kubernetes and is required to install all the other applications. It will be automatically installed as a dependency when you try to install a different app. It is installed in its own pod inside the cluster which can run the `helm` CLI in a safe environment. |
+| [Ingress](https://kubernetes.io/docs/concepts/services-networking/ingress/) | 10.2+ | Ingress can provide load balancing, SSL termination and name-based virtual hosting. It acts as a web proxy for your applications and is useful if you want to use [Auto DevOps](../../../topics/autodevops/index.md) or deploy your own web apps. |

+For large projects it may take a while to import all data. To reduce the time

+
+* `github_importer`
+* `github_importer_advance_stage`
+
+For an optimal experience we recommend having at least 4 Sidekiq processes (each

+(e.g. issues) in parallel.

+Reducing the time spent in cloning a repository can be done by increasing

+performance SSDs) of the disks that store the Git repositories (for your GitLab
+instance). Increasing the number of Sidekiq workers will _not_ reduce the time

+# Custom Issue Tracker Service
+
+To enable the Custom Issue Tracker integration in a project, navigate to the
+[Integrations page](project_services.md#accessing-the-project-services), click
+the **Customer Issue Tracker** service, and fill in the required details on the page as described
+in the table below.
+
+| Field | Description |
+| ----- | ----------- |
+| `title`   | A title for the issue tracker (to differentiate between instances, for example) |
+| `description`   | A name for the issue tracker (to differentiate between instances, for example) |
+| `project_url`   | Currently unused. Will be changed in a future release. |
+| `issues_url`    | The URL to the issue in the issue tracker project that is linked to this GitLab project. Note that the `issues_url` requires `:id` in the URL. This ID is used by GitLab as a placeholder to replace the issue number. For example, `https://customissuetracker.com/project-name/:id`. |
+| `new_issue_url` | Currently unused. Will be changed in a future release. |
+
+
+## Referencing issues
+
+Issues are referenced with `#<ID>`, where `<ID>` is a number (example `#143`). 
+So with the example above, `#143` would refer to `https://customissuetracker.com/project-name/143`.

-## Re-ordering an issue in a list
-
-> Introduced in GitLab 9.0.
-
-Issues can be re-ordered inside of lists. This is as simple as dragging and dropping
-an issue into the order you want.
+## Issue ordering in a list
+
+When visiting a board, issues appear ordered in any list. You are able to change
+that order simply by dragging and dropping the issues. The changed order will be saved
+to the system so that anybody who visits the same board later will see the reordering,
+with some exceptions.
+
+The first time a given issue appears in any board (i.e. the first time a user
+loads a board containing that issue), it will be ordered with 
+respect to other issues in that list according to [Priority order][label-priority].
+At that point, that issue will be assigned a relative order value by the system
+representing its relative order with respect to the other issues in the list. Any time
+you drag-and-drop reorder that issue, its relative order value will change accordingly.
+Also, any time that issue appears in any board when it is loaded by a user,
+the updated relative order value will be used for the ordering. (It's only the first
+time an issue appears that it takes from the Priority order mentioned above.) This means that
+if issue `A` is drag-and-drop reordered to be above issue `B` by any user in
+a given board inside your GitLab instance, any time those two issues are subsequently
+loaded in any board in the same instance (could be a different project board or a different group board, for example), 
+that ordering will be maintained.

+Now that you have labels prioritized, you can use the 'Label priority' and 'Priority' 
+sort orders in the issues or merge requests tracker.
 
-The 'Label priority' filter puts issues with the highest priority label on top.
+In the following, everything applies to both issues and merge requests, but we'll
+refer to just issues for brevity.
 
-The 'Priority' filter sorts issues by their soonest milestone due date, then by
-label priority.
+The 'Label priority' sort order positions issues with higher priority labels
+toward the top, and issues with lower priority labels toward the bottom. A non-prioritized
+label is considered to have the lowest priority. For a given issue, we _only_ consider the
+highest priority label assigned to it in the comparison. ([We are discussing](https://gitlab.com/gitlab-org/gitlab-ce/issues/18554) 
+including all the labels in a given issue for this comparison.) Given two issues
+are equal according to this sort comparison, their relative order is equal, and

+secondarily considers the label priority comparison above. Sooner due dates results
+a higher sort order. If an issue doesn't have a milestone due date, it is equivalent to
+being assigned to a milestone that has a due date in the infinite future. Given two issues

+It is possible to generate diagrams and flowcharts from text using [Mermaid][mermaid].
+
+In order to generate a diagram or flowchart, you should write your text inside the `mermaid` block.
+
+Example:
+
+    ```mermaid
+    graph TD;
+      A-->B;
+      A-->C;
+      B-->D;
+      C-->D;
+    ```
+
+Becomes:
+
+```mermaid
+graph TD;
+  A-->B;
+  A-->C;
+  B-->D;
+  C-->D;
+```
+
+For details see the [Mermaid official page][mermaid].

+# The script is composed of 3 stages: build, test and deploy.

+#
+# The deploy stage copies the exe and msi from build stage to a network drive
+# You need to have the network drive mapped as Local System user for gitlab-runner service to see it
