+their contributions accepted by meeting our [Definition of done][done].
 
 What you can expect from them is described at https://about.gitlab.com/jobs/merge-request-coach/.
 
@@ -64,6 +64,58 @@ Merge requests may still be merged into master during this period,
 but they will go into the _next_ release, unless they are manually cherry-picked into the stable branch.
 By freezing the stable branches 2 weeks prior to a release, we reduce the risk of a last minute merge request potentially breaking things.
 
+### Between the 1st and the 7th
+
+These types of merge requests need special consideration:
+
+* **Large features**: a large feature is one that is highlighted in the kick-off
+  and the release blogpost; typically this will have its own channel in Slack
+  and a dedicated team with front-end, back-end, and UX.
+* **Small features**: any other feature request.
+
+**Large features** must be with a maintainer **by the 1st**. This means that:
+
+* There is a merge request (even if it's WIP).
+* The person (or people, if it needs a frontend and backend maintainer) who will
+  ultimately be responsible for merging this have been pinged on the MR.
+
+It's OK if merge request isn't completely done, but this allows the maintainer
+enough time to make the decision about whether this can make it in before the
+freeze. If the maintainer doesn't think it will make it, they should inform the
+developers working on it and the Product Manager responsible for the feature.
+
+The maintainer can also choose to assign a reviewer to perform an initial
+review, but this way the maintainer is unlikely to be surprised by receiving an
+MR later in the cycle.
+
+**Small features** must be with a reviewer (not necessarily maintainer) **by the
+3rd**.
+
+Most merge requests from the community do not have a specific release
+target. However, if one does and falls into either of the above categories, it's
+the reviewer's responsibility to manage the above communication and assignment
+on behalf of the community member.
+
+### On the 7th
+
+Merge requests should still be complete, following the
+[definition of done][done]. The single exception is documentation, and this can
+only be left until after the freeze if:
+
+* There is a follow-up issue to add documentation.
+* It is assigned to the person writing documentation for this feature, and they
+  are aware of it.
+* It is in the correct milestone, with the ~Deliverable label.
+
+All Community Edition merge requests from GitLab team members merged on the
+freeze date (the 7th) should have a corresponding Enterprise Edition merge
+request, even if there are no conflicts. This is to reduce the size of the
+subsequent EE merge, as we often merge a lot to CE on the release date. For more
+information, see
+[limit conflicts with EE when developing on CE][limit_ee_conflicts].
+
+### Between the 7th and the 22nd
+
 Once the stable branch is frozen, only fixes for regressions (bugs introduced in that same release)
 and security issues will be cherry-picked into the stable branch.
 Any merge requests cherry-picked into the stable branch for a previous release will also be picked into the latest stable branch.

+# Polling configuration
+
+The GitLab UI polls for updates for different resources (issue notes, issue
+titles, pipeline statuses, etc.) on a schedule appropriate to the resource.
+
+In "Application settings -> Real-time features" you can configure "Polling
+interval multiplier". This multiplier is applied to all resources at once,
+and decimal values are supported. For the sake of the examples below, we will
+say that issue notes poll every 2 seconds, and issue titles poll every 5
+seconds; these are _not_ the actual values.
+
+- 1 is the default, and recommended for most installations. (Issue notes poll
+every 2 seconds, and issue titles poll every 5 seconds.)
+- 0 will disable UI polling completely. (On the next poll, clients will stop
+polling for updates.)
+- A value greater than 1 will slow polling down. If you see issues with
+database load from lots of clients polling for updates, increasing the
+multiplier from 1 can be a good compromise, rather than disabling polling
+completely. (For example: If this is set to 2, then issue notes poll every 4
+seconds, and issue titles poll every 10 seconds.)
+- A value between 0 and 1 will make the UI poll more frequently (so updates
+will show in other sessions faster), but is **not recommended**. 1 should be
+fast enough. (For example, if this is set to 0.5, then issue notes poll every
+1 second, and issue titles poll every 2.5 seconds.)

+# GitHub import
+
+>**Note:**
+>
+>  - [Introduced][ce-10308] in GitLab 9.1.
+>  - You need a personal access token in order to retrieve and import GitHub 
+>    projects. You can get it from: https://github.com/settings/tokens
+>  - You also need to pass an username as the second argument to the rake task
+>    which will become the owner of the project.
+
+To import a project from the list of your GitHub projects available:
+
+```bash
+# Omnibus installations
+sudo gitlab-rake import:github[access_token,root,foo/bar]
+
+# Installations from source
+bundle exec rake import:github[access_token,root,foo/bar] RAILS_ENV=production
+```
+
+In this case, `access_token` is your GitHub personal access token, `root`
+is your GitLab username, and  `foo/bar` is the new GitLab namespace/project that 
+will get created from your GitHub project. Subgroups are also possible: `foo/foo/bar`.
+
+
+To import a specific GitHub project (named `foo/github_repo` here):
+
+```bash
+# Omnibus installations
+sudo gitlab-rake import:github[access_token,root,foo/bar,foo/github_repo]
+
+# Installations from source
+bundle exec rake import:github[access_token,root,foo/bar,foo/github_repo] RAILS_ENV=production

+Your migration **must be** reversible. This is very important, as it should
 be possible to downgrade in case of a vulnerability or bugs.
 
 In your migration, add a comment describing how the reversibility of the
 migration was tested.
 
+## Multi Threading
+
+Sometimes a migration might need to use multiple Ruby threads to speed up a
+migration. For this to work your migration needs to include the module
+`Gitlab::Database::MultiThreadedMigration`:
+
+```ruby
+class MyMigration < ActiveRecord::Migration
+  include Gitlab::Database::MigrationHelpers
+  include Gitlab::Database::MultiThreadedMigration
+end
+```
+
+You can then use the method `with_multiple_threads` to perform work in separate
+threads. For example:
+
+```ruby
+class MyMigration < ActiveRecord::Migration
+  include Gitlab::Database::MigrationHelpers
+  include Gitlab::Database::MultiThreadedMigration
+
+  def up
+    with_multiple_threads(4) do
+      disable_statement_timeout
+
+      # ...
+    end
+  end
+end
+```
+
+Here the call to `disable_statement_timeout` will use the connection local to
+the `with_multiple_threads` block, instead of re-using the global connection
+pool.  This ensures each thread has its own connection object, and won't time
+out when trying to obtain one.
+
+**NOTE:** PostgreSQL has a maximum amount of connections that it allows. This
+limit can vary from installation to installation. As a result it's recommended
+you do not use more than 32 threads in a single migration. Usually 4-8 threads
+should be more than enough.
+
 ## Removing indices
 
-If you need to remove index, please add a condition like in following example:
+When removing an index make sure to use the method `remove_concurrent_index` instead
+of the regular `remove_index` method. The `remove_concurrent_index` method
+automatically drops concurrent indexes when using PostgreSQL, removing the
+need for downtime. To use this method you must disable transactions by calling
+the method `disable_ddl_transaction!` in the body of your migration class like
+so:
 
 ```ruby
-remove_index :namespaces, column: :name if index_exists?(:namespaces, :name)
+class MyMigration < ActiveRecord::Migration
+  include Gitlab::Database::MigrationHelpers

+

-## Factories
+## Definitions
+
+### Unit tests
+
+Formal definition: https://en.wikipedia.org/wiki/Unit_testing
+
+These kind of tests ensure that a single unit of code (a method) works as
+expected (given an input, it has a predictable output). These tests should be
+isolated as much as possible. For example, model methods that don't do anything
+with the database shouldn't need a DB record. Classes that don't need database
+records should use stubs/doubles as much as possible.

+### Integration tests
+
+Formal definition: https://en.wikipedia.org/wiki/Integration_testing
+
+These kind of tests ensure that individual parts of the application work well together, without the overhead of the actual app environment (i.e. the browser). These tests should assert at the request/response level: status code, headers, body. They're useful to test permissions, redirections, what view is rendered etc.

+
+#### About controller tests
+
+In an ideal world, controllers should be thin. However, when this is not the
+case, it's acceptable to write a system/feature test without JavaScript instead
+of a controller test. The reason is that testing a fat controller usually
+involves a lot of stubbing, things like:

-
-- Factory definitions live in `spec/factories/`, named using the pluralization
-  of their corresponding model (`User` factories are defined in `users.rb`).
-- There should be only one top-level factory definition per file.
-- FactoryGirl methods are mixed in to all RSpec groups. This means you can (and
-  should) call `create(...)` instead of `FactoryGirl.create(...)`.
-- Make use of [traits] to clean up definitions and usages.
-- When defining a factory, don't define attributes that are not required for the
-  resulting record to pass validation.
-- When instantiating from a factory, don't supply attributes that aren't
-  required by the test.
-- Factories don't have to be limited to `ActiveRecord` objects.
-  [See example](https://gitlab.com/gitlab-org/gitlab-ce/commit/0b8cefd3b2385a21cfed779bd659978c0402766d).

-## JavaScript
-
-GitLab uses [Karma] to run its [Jasmine] JavaScript specs. They can be run on
-the command line via `bundle exec karma`.
-
-- JavaScript tests live in `spec/javascripts/`, matching the folder structure
-  of `app/assets/javascripts/`: `app/assets/javascripts/behaviors/autosize.js`
-  has a corresponding `spec/javascripts/behaviors/autosize_spec.js` file.
-- Haml fixtures required for JavaScript tests live in
-  `spec/javascripts/fixtures`. They should contain the bare minimum amount of
-  markup necessary for the test.
-
-    > **Warning:** Keep in mind that a Rails view may change and
-    invalidate your test, but everything will still pass because your fixture
-    doesn't reflect the latest view. Because of this we encourage you to
-    generate fixtures from actual rails views whenever possible.
-
-- Keep in mind that in a CI environment, these tests are run in a headless
-  browser and you will not have access to certain APIs, such as
-  [`Notification`](https://developer.mozilla.org/en-US/docs/Web/API/notification),

+
+#### About Karma
+
+As you may have noticed, Karma is both in the Unit tests and the Integration
+tests category. That's because Karma is a tool that provides an environment to
+run JavaScript tests, so you can either run unit tests (e.g. test a single
+JavaScript method), or integration tests (e.g. test a component that is composed
+of multiple components).
+
+### System tests or Feature tests
+
+Formal definition: https://en.wikipedia.org/wiki/System_testing.
+
+These kind of tests ensure the application works as expected from a user point
+of view (aka black-box testing). These tests should test a happy path for a
+given page or set of pages, and a test case should be added for any regression
+that couldn't have been caught at lower levels with better tests (i.e. if a
+regression is found, regression tests should be added at the lowest-level
+possible).

+
+#### Best practices
+
+- Create only the necessary records in the database
+- Test a happy path and a less happy path but that's it
+- Every other possible path should be tested with Unit or Integration tests
+- Test what's displayed on the page, not the internals of ActiveRecord models.
+  For instance, if you want to verify that a record was created, add
+  expectations that its attributes are displayed on the page, not that
+  `Model.count` increased by one.
+- It's ok to look for DOM elements but don't abuse it since it makes the tests
+  more brittle
+
+If we're confident that the low-level components work well (and we should be if
+we have enough Unit & Integration tests), we shouldn't need to duplicate their
+thorough testing at the System test level.
+
+It's very easy to add tests, but a lot harder to remove or improve tests, so one
+should take care of not introducing too many (slow and duplicated) specs.
+
+The reasons why we should follow these best practices are as follows:
+
+- System tests are slow to run since they spin up the entire application stack
+  in a headless browser, and even slower when they integrate a JS driver
+- When system tests run with a JavaScript driver, the tests are run in a
+  different thread than the application. This means it does not share a
+  database connection and your test will have to commit the transactions in
+  order for the running application to see the data (and vice-versa). In that
+  case we need to truncate the database after each spec instead of simply
+  rolling back a transaction (the faster strategy that's in use for other kind
+  of tests). This is slower than transactions, however, so we want to use
+  truncation only when necessary.
+
+### Black-box tests or End-to-end tests
+
+GitLab consists of [multiple pieces] such as [GitLab Shell], [GitLab Workhorse],
+[Gitaly], [GitLab Pages], [GitLab Runner], and GitLab Rails. All theses pieces
+are configured and packaged by [GitLab Omnibus].
+
+[GitLab QA] is a tool that allows to test that all these pieces integrate well
+together by building a Docker image for a given version of GitLab Rails and
+running feature tests (i.e. using Capybara) against it.
+
+The actual test scenarios and steps are [part of GitLab Rails] so that they're
+always in-sync with the codebase.

+
+## How to test at the correct level?
+
+As many things in life, deciding what to test at each level of testing is a
+trade-off:
+
+- Unit tests are usually cheap, and you should consider them like the basement
+  of your house: you need them to be confident that your code is behaving
+  correctly. However if you run only unit tests without integration / system tests, you might [miss] the [big] [picture]!
+- Integration tests are a bit more expensive, but don't abuse them. A feature test
+  is often better than an integration test that is stubbing a lot of internals.
+- System tests are expensive (compared to unit tests), even more if they require
+  a JavaScript driver. Make sure to follow the guidelines in the [Speed](#test-speed)
+  section.
+
+Another way to see it is to think about the "cost of tests", this is well
+explained [in this article][tests-cost] and the basic idea is that the cost of a
+test includes:
+
+- The time it takes to write the test
+- The time it takes to run the test every time the suite runs
+- The time it takes to understand the test
+- The time it takes to fix the test if it breaks and the underlying code is OK
+- Maybe, the time it takes to change the code to make the code testable.

+### Helpers
 
-Adding new Spinach scenarios is acceptable _only if_ the new scenario requires
-no more than one new `step` definition. If more than that is required, the
-test should be re-implemented using RSpec instead.
+Helpers are usually modules that provide some methods to hide the complexity of
+specific RSpec examples. You can define helpers in RSpec files if they're not
+intended to be shared with other specs. Otherwise, they should be be placed
+under `spec/support/helpers/`. Helpers can be placed in subfolder if they apply
+to a certain type of specs only (e.g. features, requests etc.) but shouldn't be
+if they apply to multiple type of specs.
+
+Helpers should follow the Rails naming / namespacing convention. For instance
+`spec/support/helpers/cycle_analytics_helpers.rb` should define:
+
+```ruby
+module Spec
+  module Support
+    module Helpers
+      module CycleAnalyticsHelpers
+        def create_commit_referencing_issue(issue, branch_name: random_git_name)
+          project.repository.add_branch(user, branch_name, 'master')
+          create_commit("Commit for ##{issue.iid}", issue.project, user, branch_name)
+        end
+      end
+    end
+  end
+end
+```
+
+Helpers should not change the RSpec config. For instance, the helpers module
+described above should not include:
+
+```ruby
+RSpec.configure do |config|
+  config.include Spec::Support::Helpers::CycleAnalyticsHelpers
+end
+```
+
+### Factories
+
+GitLab uses [factory_girl] as a test fixture replacement.
+
+- Factory definitions live in `spec/factories/`, named using the pluralization
+  of their corresponding model (`User` factories are defined in `users.rb`).
+- There should be only one top-level factory definition per file.
+- FactoryGirl methods are mixed in to all RSpec groups. This means you can (and
+  should) call `create(...)` instead of `FactoryGirl.create(...)`.
+- Make use of [traits] to clean up definitions and usages.
+- When defining a factory, don't define attributes that are not required for the
+  resulting record to pass validation.
+- When instantiating from a factory, don't supply attributes that aren't
+  required by the test.
+- Factories don't have to be limited to `ActiveRecord` objects.
+  [See example](https://gitlab.com/gitlab-org/gitlab-ce/commit/0b8cefd3b2385a21cfed779bd659978c0402766d).
+
+[factory_girl]: https://github.com/thoughtbot/factory_girl
+[traits]: http://www.rubydoc.info/gems/factory_girl/file/GETTING_STARTED.md#Traits
+
+### Fixtures
+
+All fixtures should be be placed under `spec/fixtures/`.
+
+### Config
+
+RSpec config files are files that change the RSpec config (i.e.
+`RSpec.configure do |config|` blocks). They should be placed under
+`spec/support/config/`.
+
+Each file should be related to a specific domain, e.g.
+`spec/support/config/capybara.rb`, `spec/support/config/carrierwave.rb`, etc.
+
+Helpers can be included in the `spec/support/config/rspec.rb` file. If a
+helpers module applies only to a certain kind of specs, it should add modifiers
+to the `config.include` call. For instance if
+`spec/support/helpers/cycle_analytics_helpers.rb` applies to `:lib` and
+`type: :model` specs only, you would write the following:
+
+```ruby
+RSpec.configure do |config|
+  config.include Spec::Support::Helpers::CycleAnalyticsHelpers, :lib
+  config.include Spec::Support::Helpers::CycleAnalyticsHelpers, type: :model
+end
+```

+## Test speed
+
+GitLab has a massive test suite that, without [parallelization], can take hours
+to run. It's important that we make an effort to write tests that are accurate
+and effective _as well as_ fast.
+
+Here are some things to keep in mind regarding test performance:
+
+- `double` and `spy` are faster than `FactoryGirl.build(...)`
+- `FactoryGirl.build(...)` and `.build_stubbed` are faster than `.create`.
+- Don't `create` an object when `build`, `build_stubbed`, `attributes_for`,
+  `spy`, or `double` will do. Database persistence is slow!
+- Use `create(:empty_project)` instead of `create(:project)` when you don't need
+  the underlying Git repository. Filesystem operations are slow!
+- Don't mark a feature as requiring JavaScript (through `@javascript` in
+  Spinach or `:js` in RSpec) unless it's _actually_ required for the test
+  to be valid. Headless browser testing is slow!
+
+[parallelization]: #test-suite-parallelization-on-the-ci
+
+### Test suite parallelization on the CI
+
+Our current CI parallelization setup is as follows:
+
+1. The `knapsack` job in the prepare stage that is supposed to ensure we have a
+  `knapsack/${CI_PROJECT_NAME}/rspec_report-master.json` file:
+  - The `knapsack/${CI_PROJECT_NAME}/rspec_report-master.json` file is fetched
+    from S3, if it's not here we initialize the file with `{}`.
+1. Each `rspec x y` job are run with `knapsack rspec` and should have an evenly
+  distributed share of tests:
+  - It works because the jobs have access to the
+    `knapsack/${CI_PROJECT_NAME}/rspec_report-master.json` since the "artifacts
+    from all previous stages are passed by default". [^1]
+  - the jobs set their own report path to
+    `KNAPSACK_REPORT_PATH=knapsack/${CI_PROJECT_NAME}/${JOB_NAME[0]}_node_${CI_NODE_INDEX}_${CI_NODE_TOTAL}_report.json`.
+  - if knapsack is doing its job, test files that are run should be listed under
+    `Report specs`, not under `Leftover specs`.
+1. The `update-knapsack` job takes all the
+  `knapsack/${CI_PROJECT_NAME}/${JOB_NAME[0]}_node_${CI_NODE_INDEX}_${CI_NODE_TOTAL}_report.json`
+  files from the `rspec x y` jobs and merge them all together into a single
+  `knapsack/${CI_PROJECT_NAME}/rspec_report-master.json` file that is then
+  uploaded to S3.
+
+After that, the next pipeline will use the up-to-date
+`knapsack/${CI_PROJECT_NAME}/rspec_report-master.json` file. The same strategy
+is used for Spinach tests as well.
+
+### Monitoring
+
+The GitLab test suite is [monitored] and a [public dashboard] is available for
+everyone to see. Feel free to look at the slowest test files and try to improve
+them.

+various operations, their impact, and how to perform them without requiring
+downtime.
 
 ## Adding Columns
 
@@ -41,50 +42,156 @@ information on how to use this method.
 
 ## Dropping Columns
 
-On PostgreSQL you can safely remove an existing column without the need for
-downtime. When you drop a column in PostgreSQL it's not immediately removed,
-instead it is simply disabled. The data is removed on the next vacuum run.
+Removing columns is tricky because running GitLab processes may still be using
+the columns. To work around this you will need two separate merge requests and
+releases: one to ignore and then remove the column, and one to remove the ignore
+rule.
 
-On MySQL this operation requires downtime.
+### Step 1: Ignoring The Column
 
-While database wise dropping a column may be fine on PostgreSQL this operation
-still requires downtime because the application code may still be using the
-column that was removed. For example, consider the following migration:
+The first step is to ignore the column in the application code. This is
+necessary because Rails caches the columns and re-uses this cache in various
+places. This can be done by including the `IgnorableColumn` module into the
+model, followed by defining the columns to ignore. For example, to ignore
+`updated_at` in the User model you'd use the following:
 
 ```ruby
-class MyMigration < ActiveRecord::Migration
-  def change
-    remove_column :projects, :dummy
-  end
+class User < ActiveRecord::Base
+  include IgnorableColumn
+
+  ignore_column :updated_at
 end
 ```
 
-Now imagine that the GitLab instance is running and actively uses the `dummy`
-column. If we were to run the migration this would result in the GitLab instance
-producing errors whenever it tries to use the `dummy` column.
+Once added you should create a _post-deployment_ migration that removes the
+column. Both these changes should be submitted in the same merge request.
 
-As a result of the above downtime _is_ required when removing a column, even
-when using PostgreSQL.
+### Step 2: Removing The Ignore Rule
+
+Once the changes from step 1 have been released & deployed you can set up a
+separate merge request that removes the ignore rule. This merge request can
+simply remove the `ignore_column` line, and the `include IgnorableColumn` line
+if no other `ignore_column` calls remain.
 
 ## Renaming Columns
 
-Renaming columns requires downtime as running GitLab instances will continue
-using the old column name until a new version is deployed. This can result
-in the instance producing errors, which in turn can impact the user experience.
+Renaming columns the normal way requires downtime as an application may continue
+using the old column name during/after a database migration. To rename a column
+without requiring downtime we need two migrations: a regular migration, and a
+post-deployment migration. Both these migration can go in the same release.
 
-## Changing Column Constraints
+### Step 1: Add The Regular Migration
+
+First we need to create the regular migration. This migration should use
+`Gitlab::Database::MigrationHelpers#rename_column_concurrently` to perform the
+renaming. For example
+
+```ruby
+# A regular migration in db/migrate
+class RenameUsersUpdatedAtToUpdatedAtTimestamp < ActiveRecord::Migration
+  include Gitlab::Database::MigrationHelpers
+
+  disable_ddl_transaction!
+
+  def up
+    rename_column_concurrently :users, :updated_at, :updated_at_timestamp
+  end
+
+  def down
+    cleanup_concurrent_column_rename :users, :updated_at_timestamp, :updated_at
+  end
+end
+```
+
+This will take care of renaming the column, ensuring data stays in sync, copying
+over indexes and foreign keys, etc.
+
+**NOTE:** if a column contains 1 or more indexes that do not contain the name of
+the original column, the above procedure will fail. In this case you will first
+need to rename these indexes.
 
-Generally changing column constraints requires checking all rows in the table to
-see if they meet the new constraint, unless a constraint is _removed_. For
-example, changing a column that previously allowed NULL values to not allow NULL
-values requires the database to verify all existing rows.
+### Step 2: Add A Post-Deployment Migration
 
-The specific behaviour varies a bit between databases but in general the safest
-approach is to assume changing constraints requires downtime.
+The renaming procedure requires some cleaning up in a post-deployment migration.
+We can perform this cleanup using
+`Gitlab::Database::MigrationHelpers#cleanup_concurrent_column_rename`:
+
+```ruby
+# A post-deployment migration in db/post_migrate
+class CleanupUsersUpdatedAtRename < ActiveRecord::Migration
+  include Gitlab::Database::MigrationHelpers
+
+  disable_ddl_transaction!
+
+  def up
+    cleanup_concurrent_column_rename :users, :updated_at, :updated_at_timestamp
+  end
+
+  def down
+    rename_column_concurrently :users, :updated_at_timestamp, :updated_at
+  end
+end
+```
+
+## Changing Column Constraints
+
+Adding or removing a NOT NULL clause (or another constraint) can typically be
+done without requiring downtime. However, this does require that any application
+changes are deployed _first_. Thus, changing the constraints of a column should
+happen in a post-deployment migration.
 
 ## Changing Column Types
 
-This operation requires downtime.
+Changing the type of a column can be done using
+`Gitlab::Database::MigrationHelpers#change_column_type_concurrently`. This
+method works similarly to `rename_column_concurrently`. For example, let's say
+we want to change the type of `users.username` from `string` to `text`.
+
+### Step 1: Create A Regular Migration
+
+A regular migration is used to create a new column with a temporary name along
+with setting up some triggers to keep data in sync. Such a migration would look
+as follows:
+
+```ruby
+# A regular migration in db/migrate
+class ChangeUsersUsernameStringToText < ActiveRecord::Migration
+  include Gitlab::Database::MigrationHelpers
+
+  disable_ddl_transaction!
+
+  def up
+    change_column_type_concurrently :users, :username, :text
+  end
+
+  def down
+    cleanup_concurrent_column_type_change :users, :username
+  end
+end
+```
+
+### Step 2: Create A Post Deployment Migration
+
+Next we need to clean up our changes using a post-deployment migration:
+
+```ruby
+# A post-deployment migration in db/post_migrate
+class ChangeUsersUsernameStringToTextCleanup < ActiveRecord::Migration
+  include Gitlab::Database::MigrationHelpers
+
+  disable_ddl_transaction!
+
+  def up
+    cleanup_concurrent_column_type_change :users
+  end
+
+  def down
+    change_column_type_concurrently :users, :username, :string
+  end
+end
+```
+
+And that's it, we're done!

-This operation requires downtime as application code may still be using the

+Dropping tables can be done safely using a post-deployment migration, but only

 ## Adding Foreign Keys
 
-Adding foreign keys acquires an exclusive lock on both the source and target
-tables in PostgreSQL. This requires downtime as otherwise the entire application
-grinds to a halt for the duration of the operation.
+Adding foreign keys usually works in 3 steps:
+
+1. Start a transaction
+1. Run `ALTER TABLE` to add the constraint(s)
+1. Check all existing data
 
-On MySQL this operation also requires downtime _unless_ foreign key checks are

+ensures that when PostgreSQL is used no downtime is needed.
 
 ## Removing Foreign Keys
 
-This operation should not require downtime on both PostgreSQL and MySQL.
+This operation does not require downtime.
 
-## Updating Data
+## Data Migrations
 
-Updating data should generally be safe. The exception to this is data that's
-being migrated from one version to another while the application still produces
-data in the old version.
+Data migrations can be tricky. The usual approach to migrate data is to take a 3
+step approach:
 
-For example, imagine the application writes the string `'dog'` to a column but
-it really is meant to write `'cat'` instead. One might think that the following
-migration is all that is needed to solve this problem:
+1. Migrate the initial batch of data
+1. Deploy the application code
+1. Migrate any remaining data
 
-```ruby
-class MyMigration < ActiveRecord::Migration
-  def up
-    execute("UPDATE some_table SET column = 'cat' WHERE column = 'dog';")
-  end
-end
-```
+Usually this works, but not always. For example, if a field's format is to be
+changed from JSON to something else we have a bit of a problem. If we were to
+change existing data before deploying application code we'll most likely run
+into errors. On the other hand, if we were to migrate after deploying the
+application code we could run into the same problems.
+
+If you merely need to correct some invalid data, then a post-deployment
+migration is usually enough. If you need to change the format of data (e.g. from
+JSON to something else) it's typically best to add a new column for the new data
+format, and have the application use that. In such a case the procedure would
+be:
 
-Unfortunately this is not enough. Because the application is still running and
-using the old value this may result in the table still containing rows where
-`column` is set to `dog`, even after the migration finished.
+1. Add a new column in the new format
+1. Copy over existing data to this new column
+1. Deploy the application code
+1. In a post-deployment migration, copy over any remaining data
 
-In these cases downtime _is_ required, even for rarely updated tables.
+In general there is no one-size-fits-all solution, therefore it's best to
+discuss these kind of migrations in a merge request to make sure they are
+implemented in the best way possible.

+Starting with GitLab 9.1.0 it's possible to upgrade to a newer major, minor, or patch version of GitLab
+without having to take your GitLab instance offline. However, for this to work
+there are the following requirements:
+
+1. You can only upgrade 1 minor release at a time. So from 9.1 to 9.2, not to 9.3.
+2. You have to be on the most recent patch release. For example, if 9.1.15 is the last
+   release of 9.1 then you can safely upgrade from that version to any 9.2.x version.
+   However, if you are running 9.1.14 you first need to upgrade to 9.1.15.

+# Protected Tags
+
+> [Introduced][ce-10356] in GitLab 9.1.
+
+Protected Tags allow control over who has permission to create tags as well as preventing accidental update or deletion once created. Each rule allows you to match either an individual tag name, or use wildcards to control multiple tags at once.
+
+This feature evolved out of [Protected Branches](protected_branches.md)
+
+## Overview
+
+Protected tags will prevent anyone from updating or deleting the tag, as and will prevent creation of matching tags based on the permissions you have selected. By default, anyone without Master permission will be prevented from creating tags.
+
+
+## Configuring protected tags
+
+To protect a tag, you need to have at least Master permission level.
+
+1. Navigate to the project's Settings -> Repository page
+
+    ![Repository Settings](img/project_repository_settings.png)
+
+1. From the **Tag** dropdown menu, select the tag you want to protect or type and click `Create wildcard`. In the screenshot below, we chose to protect all tags matching `v*`.
+
+    ![Protected tags page](img/protected_tags_page.png)
+
+1. From the `Allowed to create` dropdown, select who will have permission to create matching tags and then click `Protect`.
+
+    ![Allowed to create tags dropdown](img/protected_tags_permissions_dropdown.png)
+
+1. Once done, the protected tag will appear in the "Protected tags" list.
+
+    ![Protected tags list](img/protected_tags_list.png)
+
+## Wildcard protected tags
+
+You can specify a wildcard protected tag, which will protect all tags
+matching the wildcard. For example:
+
+| Wildcard Protected Tag | Matching Tags                 |
+|------------------------+-------------------------------|
+| `v*`                   | `v1.0.0`, `version-9.1`       |
+| `*-deploy`             | `march-deploy`, `1.0-deploy`  |
+| `*gitlab*`             | `gitlab`, `gitlab/v1`         |
+| `*`                    | `v1.0.1rc2`, `accidental-tag` |
+
+
+Two different wildcards can potentially match the same tag. For example,
+`*-stable` and `production-*` would both match a `production-stable` tag.
+In that case, if _any_ of these protected tags have a setting like
+"Allowed to create", then `production-stable` will also inherit this setting.
+
+If you click on a protected tag's name, you will be presented with a list of
+all matching tags:
+
+![Protected tag matches](img/protected_tag_matches.png)

+# Search through GitLab
+
+## Issues and merge requests
+
+To search through issues and merge requests in multiple projects, you can use the left-sidebar.
+
+Click the menu bar, then **Issues** or **Merge Requests**, which work in the same way,
+therefore, the following notes are valid for both.
+
+The number displayed on their right represents the number of issues and merge requests assigned to you.
+
+![menu bar - issues and MRs assigned to you](img/left_menu_bar.png)
+
+When you click **Issues**, you'll see the opened issues assigned to you straight away:
+
+![Issues assigned to you](img/issues_assigned_to_you.png)
+
+You can filter them by **Author**, **Assignee**, **Milestone**, and **Labels**,
+searching through **Open**, **Closed**, and **All** issues.
+
+Of course, you can combine all filters together.
+
+### Issues and MRs assigned to you or created by you
+
+You'll find a shortcut to issues and merge requests create by you or assigned to you
+on the search field on the top-right of your screen:
+
+![shortcut to your issues and mrs](img/issues_mrs_shortcut.png)
+
+## Issues and merge requests per project
+
+If you want to search for issues present in a specific project, navigate to
+a project's **Issues** tab, and click on the field **Search or filter results...**. It will
+display a dropdown menu, from which you can add filters per author, assignee, milestone, label,
+and weight. When done, press **Enter** on your keyboard to filter the issues.
+
+![filter issues in a project](img/filter_issues_project.gif)
+
+The same process is valid for merge requests. Navigate to your project's **Merge Requests** tab,
+and click **Search or filter results...**. Merge requests can be filtered by author, assignee,
+milestone, and label.
+
+### Shortcut
+
+You'll also find a shortcut on the search field on the top-right of the project's dashboard to
+quickly access issues and merge requests created or assigned to you within that project:
+
+![search per project - shortcut](img/project_search.png)
+
+## Todos
+
+Your [todos](../../workflow/todos.md#gitlab-todos) can be searched by "to do" and "done".
+You can [filter](../../workflow/todos.md#filtering-your-todos) them per project,
+author, type, and action. Also, you can sort them by
+[**Label priority**](../../user/project/labels.md#prioritize-labels),
+**Last created** and **Oldest created**.
+
+## Projects
+
+You can search through your projects from the left menu, by clicking the menu bar, then **Projects**.
+On the field **Filter by name**, type the project or group name you want to find, and GitLab
+will filter them for you as you type.
+
+You can also look for the projects you starred (**Starred projects**), and **Explore** all
+public and internal projects available in GitLab.com, from which you can filter by visibitily,
+through **Trending**, best rated with **Most starts**, or **All** of them.
+
+You can also sort them by **Name**, **Last created**, **Oldest created**, **Last updated**,
+**Oldest updated**, **Owner**, and choose to hide or show **archived projects**:
+
+![sort projects](img/sort_projects.png)
+
+## Groups
+
+Similarly to [projects search](#projects), you can search through your groups from
+the left menu, by clicking the menu bar, then **Groups**.
+
+On the field **Filter by name**, type the group name you want to find, and GitLab
+will filter them for you as you type.
+
+You can also **Explore** all public and internal groups available in GitLab.com,
+and sort them by **Last created**, **Oldest created**, **Last updated**, or **Oldest updated**.
+
+## Issue Boards
+
+From an [Issue Board](../../user/project/issue_board.md), you can filter issues by **Author**, **Assignee**, **Milestone**, and **Labels**.
+You can also filter them by name (issue title), from the field **Filter by name**, which is loaded as you type.
+
+When you want to search for issues to add to lists present in your Issue Board, click
+the button **Add issues** on the top-right of your screen, opening a modal window from which
+you'll be able to, besides filtering them by **Name**, **Author**, **Assignee**, **Milestone**,
+and **Labels**, select multiple issues to add to a list of your choice:
