+# Contributing code to Matrix
+
+Everyone is welcome to contribute code to Matrix
+(https://github.com/matrix-org), provided that they are willing to license
+their contributions under the same license as the project itself. We follow a
+simple 'inbound=outbound' model for contributions: the act of submitting an
+'inbound' contribution means that the contributor agrees to license the code
+under the same terms as the project's overall 'outbound' license - in our
+case, this is almost always Apache Software License v2 (see [LICENSE](LICENSE)).
+
+## How to contribute
+
+The preferred and easiest way to contribute changes to Matrix is to fork the
+relevant project on github, and then [create a pull request](
+https://help.github.com/articles/using-pull-requests/) to ask us to pull
+your changes into our repo.
+
+**The single biggest thing you need to know is: please base your changes on
+the develop branch - *not* master.**
+
+We use the master branch to track the most recent release, so that folks who
+blindly clone the repo and automatically check out master get something that
+works. Develop is the unstable branch where all the development actually
+happens: the workflow is that contributors should fork the develop branch to
+make a 'feature' branch for a particular contribution, and then make a pull
+request to merge this back into the matrix.org 'official' develop branch. We
+use github's pull request workflow to review the contribution, and either ask
+you to make any refinements needed or merge it and make them ourselves. The
+changes will then land on master when we next do a release.
+
+We use [Buildkite](https://buildkite.com/matrix-dot-org/synapse) for continuous
+integration. If your change breaks the build, this will be shown in GitHub, so
+please keep an eye on the pull request for feedback.
+
+To run unit tests in a local development environment, you can use:
+
+- ``tox -e py35`` (requires tox to be installed by ``pip install tox``)
+  for SQLite-backed Synapse on Python 3.5.
+- ``tox -e py36`` for SQLite-backed Synapse on Python 3.6.
+- ``tox -e py36-postgres`` for PostgreSQL-backed Synapse on Python 3.6
+  (requires a running local PostgreSQL with access to create databases).
+- ``./test_postgresql.sh`` for PostgreSQL-backed Synapse on Python 3.5
+  (requires Docker). Entirely self-contained, recommended if you don't want to
+  set up PostgreSQL yourself.
+
+Docker images are available for running the integration tests (SyTest) locally,
+see the [documentation in the SyTest repo](
+https://github.com/matrix-org/sytest/blob/develop/docker/README.md) for more
+information.
+
+## Code style
+
+All Matrix projects have a well-defined code-style - and sometimes we've even
+got as far as documenting it... For instance, synapse's code style doc lives
+[here](docs/code_style.md).
+
+To facilitate meeting these criteria you can run `scripts-dev/lint.sh`
+locally. Since this runs the tools listed in the above document, you'll need
+python 3.6 and to install each tool:
+
+```
+# Install the dependencies
+pip install -U black flake8 isort
+
+# Run the linter script
+./scripts-dev/lint.sh
+```
+
+**Note that the script does not just test/check, but also reformats code, so you
+may wish to ensure any new code is committed first**. By default this script
+checks all files and can take some time; if you alter only certain files, you
+might wish to specify paths as arguments to reduce the run-time:
+
+```
+./scripts-dev/lint.sh path/to/file1.py path/to/file2.py path/to/folder
+```
+
+Before pushing new changes, ensure they don't produce linting errors. Commit any
+files that were corrected.
+
+Please ensure your changes match the cosmetic style of the existing project,
+and **never** mix cosmetic and functional changes in the same commit, as it
+makes it horribly hard to review otherwise.
+
+
+## Changelog
+
+All changes, even minor ones, need a corresponding changelog / newsfragment
+entry. These are managed by [Towncrier](https://github.com/hawkowl/towncrier).
+
+To create a changelog entry, make a new file in the `changelog.d` directory named
+in the format of `PRnumber.type`. The type can be one of the following:
+
+* `feature`
+* `bugfix`
+* `docker` (for updates to the Docker image)
+* `doc` (for updates to the documentation)
+* `removal` (also used for deprecations)
+* `misc` (for internal-only changes)
+
+The content of the file is your changelog entry, which should be a short
+description of your change in the same style as the rest of our [changelog](
+https://github.com/matrix-org/synapse/blob/master/CHANGES.md). The file can
+contain Markdown formatting, and should end with a full stop ('.') for
+consistency.
+
+Adding credits to the changelog is encouraged, we value your
+contributions and would like to have you shouted out in the release notes!
+
+For example, a fix in PR #1234 would have its changelog entry in
+`changelog.d/1234.bugfix`, and contain content like "The security levels of
+Florbs are now validated when received over federation. Contributed by Jane
+Matrix.".
+
+## Debian changelog
+
+Changes which affect the debian packaging files (in `debian`) are an
+exception.
+
+In this case, you will need to add an entry to the debian changelog for the
+next release. For this, run the following command:
+
+```
+dch
+```
+
+This will make up a new version number (if there isn't already an unreleased
+version in flight), and open an editor where you can add a new changelog entry.
+(Our release process will ensure that the version number and maintainer name is
+corrected for the release.)
+
+If your change affects both the debian packaging *and* files outside the debian
+directory, you will need both a regular newsfragment *and* an entry in the
+debian changelog. (Though typically such changes should be submitted as two
+separate pull requests.)
+
+## Sign off
+
+In order to have a concrete record that your contribution is intentional
+and you agree to license it under the same terms as the project's license, we've adopted the
+same lightweight approach that the Linux Kernel
+[submitting patches process](
+https://www.kernel.org/doc/html/latest/process/submitting-patches.html#sign-your-work-the-developer-s-certificate-of-origin>),
+[Docker](https://github.com/docker/docker/blob/master/CONTRIBUTING.md), and many other
+projects use: the DCO (Developer Certificate of Origin:
+http://developercertificate.org/). This is a simple declaration that you wrote
+the contribution or otherwise have the right to contribute it to Matrix:

+do!

+Upgrading to v1.7.0
+===================
+
+In an attempt to configure Synapse in a privacy preserving way, the default
+behaviours of ``allow_public_rooms_without_auth`` and
+``allow_public_rooms_over_federation`` have been inverted. This means that by
+default, only authenticated users querying the Client/Server API will be able
+to query the room directory, and relatedly that the server will not share
+room directory information with other servers over federation.
+
+If your installation does not explicitly set these settings one way or the other
+and you want either setting to be ``true`` then it will necessary to update
+your homeserver configuration file accordingly.

+For more details on the surrounding context see our `explainer
+<https://matrix.org/blog/2019/11/09/avoiding-unwelcome-visitors-on-private-matrix-servers>`_.

+disallow any further invites or joins.
+
+The local server will only have the power to move local user and room aliases to

+## API
+
+You will need to authenticate with an access token for an admin user.
+
+### URL
+
+`POST /_synapse/admin/v1/shutdown_room/{room_id}`
+
+### URL Parameters
+
+* `room_id` - The ID of the room (e.g `!someroom:example.com`)
+
+### JSON Body Parameters
+
+* `new_room_user_id` - Required. A string representing the user ID of the user that will admin
+                       the new room that all users in the old room will be moved to.
+* `room_name` - Optional. A string representing the name of the room that new users will be
+                invited to.
+* `message` - Optional. A string containing the first message that will be sent as
+              `new_room_user_id` in the new room. Ideally this will clearly convey why the
+               original room was shut down.
+              
+If not specified, the default value of `room_name` is "Content Violation
+Notification". The default value of `message` is "Sharing illegal content on
+othis server is not permitted and rooms in violation will be blocked."
+
+### Response Parameters
+
+* `kicked_users` - An integer number representing the number of users that
+                   were kicked.
+* `failed_to_kick_users` - An integer number representing the number of users
+                           that were not kicked.
+* `local_aliases` - An array of strings representing the local aliases that were migrated from
+                    the old room to the new.
+* `new_room_id` - A string representing the room ID of the new room.

-which do not understand .well-known URIs, so if you removed your SRV record
-you would no longer be able to federate with them.
-
-It is therefore best to leave the SRV record in place for now. Synapse 0.34 and
-earlier will follow the SRV record (and not care about the invalid
-certificate). Synapse 0.99 and later will follow the .well-known URI, with the
-correct certificate chain.
+No. You can use either `.well-known` delegation or use an SRV record for delegation. You
+do not need to use both to delegate to the same location.
 
 #### Can I manage my own certificates rather than having Synapse renew certificates itself?

+# SAML Mapping Providers
+
+A SAML mapping provider is a Python class (loaded via a Python module) that
+works out how to map attributes of a SAML response object to Matrix-specific
+user attributes. Details such as user ID localpart, displayname, and even avatar
+URLs are all things that can be mapped from talking to a SSO service.
+
+As an example, a SSO service may return the email address
+"john.smith@example.com" for a user, whereas Synapse will need to figure out how
+to turn that into a displayname when creating a Matrix user for this individual.
+It may choose `John Smith`, or `Smith, John [Example.com]` or any number of
+variations. As each Synapse configuration may want something different, this is
+where SAML mapping providers come into play.
+
+## Enabling Providers
+
+External mapping providers are provided to Synapse in the form of an external
+Python module. Retrieve this module from [PyPi](https://pypi.org) or elsewhere,
+then tell Synapse where to look for the handler class by editing the
+`saml2_config.user_mapping_provider.module` config option.
+
+`saml2_config.user_mapping_provider.config` allows you to provide custom
+configuration options to the module. Check with the module's documentation for
+what options it provides (if any). The options listed by default are for the
+user mapping provider built in to Synapse. If using a custom module, you should
+comment these options out and use those specified by the module instead.
+
+## Building a Custom Mapping Provider
+
+A custom mapping provider must specify the following methods:
+
+* `__init__(self, parsed_config)`
+   - Arguments:
+     - `parsed_config` - A configuration object that is the return value of the
+       `parse_config` method. You should set any configuration options needed by
+       the module here.
+* `saml_response_to_user_attributes(self, saml_response, failures)`
+    - Arguments:
+      - `saml_response` - A `saml2.response.AuthnResponse` object to extract user
+                          information from.
+      - `failures` - An `int` that represents the amount of times the returned
+                     mxid localpart mapping has failed.  This should be used
+                     to create a deduplicated mxid localpart which should be
+                     returned instead. For example, if this method returns
+                     `john.doe` as the value of `mxid_localpart` in the returned
+                     dict, and that is already taken on the homeserver, this
+                     method will be called again with the same parameters but
+                     with failures=1. The method should then return a different
+                     `mxid_localpart` value, such as `john.doe1`.
+    - This method must return a dictionary, which will then be used by Synapse
+      to build a new user. The following keys are allowed:
+       * `mxid_localpart` - Required. The mxid localpart of the new user.
+       * `displayname` - The displayname of the new user. If not provided, will default to
+                         the value of `mxid_localpart`.
+* `parse_config(config)`
+    - This method should have the `@staticmethod` decoration.
+    - Arguments:
+        - `config` - A `dict` representing the parsed content of the
+          `saml2_config.user_mapping_provider.config` homeserver config option.
+           Runs on homeserver startup. Providers should extract any option values
+           they need here.
+    - Whatever is returned will be passed back to the user mapping provider module's
+      `__init__` method during construction.
+* `get_saml_attributes(config)`
+    - This method should have the `@staticmethod` decoration.
+    - Arguments:
+        - `config` - A object resulting from a call to `parse_config`.
+    - Returns a tuple of two sets. The first set equates to the saml auth
+      response attributes that are required for the module to function, whereas
+      the second set consists of those attributes which can be used if available,
+      but are not necessary.
+
+## Synapse's Default Provider
+
+Synapse has a built-in SAML mapping provider if a custom provider isn't
+specified in the config. It is located at
+[`synapse.handlers.saml_handler.DefaultSamlMappingProvider`](../synapse/handlers/saml_handler.py).
