+# Serializing Data
+
+**Summary:** don't store serialized data in the database, use separate columns
+and/or tables instead.
+
+Rails makes it possible to store serialized data in JSON, YAML or other formats.
+Such a field can be defined as follows:
+
+```ruby
+class Issue < ActiveRecord::Model
+  serialize :custom_fields
+end
+```
+
+While it may be tempting to store serialized data in the database there are many
+problems with this. This document will outline these problems and provide an
+alternative.
+
+## Serialized Data Is Less Powerful
+
+When using a relational database you have the ability to query individual
+fields, change the schema, index data and so forth. When you use serialized data
+all of that becomes either very difficult or downright impossible. While
+PostgreSQL does offer the ability to query JSON fields it is mostly meant for
+very specialized use cases, and not for more general use. If you use YAML in
+turn there's no way to query the data at all.
+
+## Waste Of Space
+
+Storing serialized data such as JSON or YAML will end up wasting a lot of space.
+This is because these formats often include additional characters (e.g. double
+quotes or newlines) besides the data that you are storing.
+
+## Difficult To Manage
+
+There comes a time where you will need to add a new field to the serialized
+data, or change an existing one. Using serialized data this becomes difficult
+and very time consuming as the only way of doing so is to re-write all the
+stored values. To do so you would have to:
+
+1. Retrieve the data
+1. Parse it into a Ruby structure
+1. Mutate it
+1. Serialize it back to a String
+1. Store it in the database
+
+On the other hand, if one were to use regular columns adding a column would be
+as easy as this:
+
+```sql
+ALTER TABLE table_name ADD COLUMN column_name type;
+```
+
+Such a query would take very little to no time and would immediately apply to
+all rows, without having to re-write large JSON or YAML structures.
+
+Finally, there comes a time when the JSON or YAML structure is no longer
+sufficient and you need to migrate away from it. When storing only a few rows
+this may not be a problem, but when storing millions of rows such a migration
+can easily take hours or even days to complete.
+
+## Relational Databases Are Not Document Stores
+
+When storing data as JSON or YAML you're essentially using your database as if
+it were a document store (e.g. MongoDB), except you're not using any of the
+powerful features provided by a typical RDBMS _nor_ are you using any of the
+features provided by a typical document store (e.g. the ability to index fields
+of documents with variable fields). In other words, it's a waste.
+
+## Consistent Fields
+
+One argument sometimes made in favour of serialized data is having to store
+widely varying fields and values. Sometimes this is truly the case, and then
+perhaps it might make sense to use serialized data. However, in 99% of the cases
+the fields and types stored tend to be the same for every row. Even if there is
+a slight difference you can still use separate columns and just not set the ones
+you don't need.
+
+## The Solution
+
+The solution is very simple: just use separate columns and/or separate tables.
+This will allow you to use all the features provided by your database, it will
+make it easier to manage and migrate the data, you'll conserve space, you can
+index the data efficiently and so forth.

+
+See the [Kubernetes documentation](https://kubernetes.io/docs/tutorials/services/source-ip/#source-ip-for-services-with-typeloadbalancer) for more information.
+
+To fix this you can add the following service annotation to your `values.yaml`
+
+```yaml
+## For minikube, set this to NodePort, elsewhere use LoadBalancer
+## ref: http://kubernetes.io/docs/user-guide/services/#publishing-services---service-types

+
+>**Note:**
+If you are using the ingress routing, you will likely also need to specify the annotation on the service for the ingress
+controller. For `nginx-ingress` you can check the
+[configuration documentation](https://github.com/kubernetes/charts/blob/master/stable/nginx-ingress/README.md#configuration)
+on how to add the annotation to the  `controller.service.annotations` array.
+
+>**Note:**
+When using the `nginx-ingress` controller on Google Container Engine (GKE), and using the `external-traffic` annotation,
+you will need to additionally set the `controller.kind` to be DaemonSet. Otherwise only pods running on the same node
+as the nginx controller will be able to reach GitLab. This may result in pods within your cluster not being able to reach GitLab.

+# From 9.2 to 9.3
+
+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-2.3.3.tar.gz
+echo '1014ee699071aa2ddd501907d18cbe15399c997d ruby-2.3.3.tar.gz' | shasum -c - && tar xzf ruby-2.3.3.tar.gz
+cd ruby-2.3.3
+./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 --location https://yarnpkg.com/install.sh | bash -
+```
+
+More information can be found on the [yarn website](https://yarnpkg.com/en/docs/install).
+
+### 5. Update Go
+
+NOTE: GitLab 9.3 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 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
+```
+
+For GitLab Community Edition:
+
+```bash
+cd /home/git/gitlab
+
+sudo -u git -H git checkout 9-3-stable
+```
+
+OR
+
+For GitLab Enterprise Edition:
+
+```bash
+cd /home/git/gitlab
+
+sudo -u git -H git checkout 9-3-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 v$(</home/git/gitlab/GITLAB_SHELL_VERSION)
+sudo -u git -H bin/compile
+```
+
+### 6. Update gitlab-workhorse
+
+Install and compile gitlab-workhorse. This requires
+[Go 1.5](https://golang.org/dl) which should already be on your system from
+GitLab 8.1. GitLab-Workhorse uses [GNU Make](https://www.gnu.org/software/make/).
+If you are not using Linux you may have to run `gmake` instead of
+`make` below.
+
+```bash
+cd /home/git/gitlab-workhorse
+
+sudo -u git -H git fetch --all --tags
+sudo -u git -H git checkout v$(</home/git/gitlab/GITLAB_WORKHORSE_VERSION)
+sudo -u git -H make
+```
+
+### 7. Update Gitaly
+
+If you have not yet set up Gitaly then follow [Gitaly section of the installation
+guide](../install/installation.md#install-gitaly).
+
+#### 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 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/9-2-stable:config/gitlab.yml.example origin/9-3-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/9-2-stable:lib/support/nginx/gitlab-ssl origin/9-3-stable:lib/support/nginx/gitlab-ssl
+
+# For HTTP configurations
+git diff origin/9-2-stable:lib/support/nginx/gitlab origin/9-3-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/9-3-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/9-2-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/9-2-stable:lib/support/init.d/gitlab.default.example origin/9-3-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
+```
+
+### 11. 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
+
+# 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).
+
+### 12. Start application
+
+```bash
+sudo service gitlab start
+sudo service nginx restart
+```
+
+### 13. 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 (9.2)
+
+### 1. Revert the code to the previous version
+
+Follow the [upgrade guide from 9.1 to 9.2](9.1-to-9.2.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.

+This is possible for e.g. SaaS applications, but there are many cases where this is not possible.
 One would be a situation where you are not in control of the exact release moment, for example an iOS application that needs to pass App Store validation.

-// TaskList Behavior
-//
-/*= 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.
