-# 7. Turn coffee and documentation into code and documentation!
+## Code style
 
 Synapse's code style is documented [here](docs/code_style.md). Please follow
 it, including the conventions for the [sample configuration
 file](docs/code_style.md#configuration-file-format).
 
-There is a growing amount of documentation located in the [docs](docs)
-directory. This documentation is intended primarily for sysadmins running their
-own Synapse instance, as well as developers interacting externally with
-Synapse. [docs/dev](docs/dev) exists primarily to house documentation for
-Synapse developers. [docs/admin_api](docs/admin_api) houses documentation
-regarding Synapse's Admin API, which is used mostly by sysadmins and external
-service developers.
+Many of the conventions are enforced by scripts which are run as part of the
+[continuous integration system](#continuous-integration-and-testing). To help
+check if you have followed the code style, you can run `scripts-dev/lint.sh`
+locally. You'll need python 3.6 or later, and to install a number of tools:
 
-If you add new files added to either of these folders, please use [GitHub-Flavoured
-Markdown](https://guides.github.com/features/mastering-markdown/).

-# 8. Test, test, test!
-<a name="test-test-test"></a>
-
-While you're developing and before submitting a patch, you'll
-want to test your code.
-
-## Run the linters.
-
-The linters look at your code and do two things:
-
-- ensure that your code follows the coding style adopted by the project;
-- catch a number of errors in your code.
-
-They're pretty fast, don't hesitate!
-
-```sh
-source ./env/bin/activate
+# Run the linter script
 ./scripts-dev/lint.sh
 ```
 
-Note that this script *will modify your files* to fix styling errors.
-Make sure that you have saved all your files.
+**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**.
 
-If you wish to restrict the linters to only the files changed since the last commit
-(much faster!), you can instead run:
+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:
 
-```sh
-source ./env/bin/activate
-./scripts-dev/lint.sh -d
 ```
-
-Or if you know exactly which files you wish to lint, you can instead run:
-
-```sh
-source ./env/bin/activate
 ./scripts-dev/lint.sh path/to/file1.py path/to/file2.py path/to/folder
 ```
 
-## Run the unit tests.
-
-The unit tests run parts of Synapse, including your changes, to see if anything
-was broken. They are slower than the linters but will typically catch more errors.
-
-```sh
-source ./env/bin/activate
-trial tests
-```
-
-If you wish to only run *some* unit tests, you may specify
-another module instead of `tests` - or a test class or a method:
-
-```sh
-source ./env/bin/activate
-trial tests.rest.admin.test_room tests.handlers.test_admin.ExfiltrateData.test_invite
-```
-
-If your tests fail, you may wish to look at the logs:
-
-```sh
-less _trial_temp/test.log
-```
-
-## Run the integration tests.
-
-The integration tests are a more comprehensive suite of tests. They
-run a full version of Synapse, including your changes, to check if
-anything was broken. They are slower than the unit tests but will
-typically catch more errors.
-
-The following command will let you run the integration test with the most common
-configuration:
-
-```sh
-$ docker run --rm -it -v /path/where/you/have/cloned/the/repository\:/src:ro -v /path/to/where/you/want/logs\:/logs matrixdotorg/sytest-synapse:py37
-```
-
-This configuration should generally cover  your needs. For more details about other configurations, see [documentation in the SyTest repo](https://github.com/matrix-org/sytest/blob/develop/docker/README.md).
-
-
-# 9. Submit your patch.
-
-Once you're happy with your patch, it's time to prepare a Pull Request.
-
-To prepare a Pull Request, please:
-
-1. verify that [all the tests pass](#test-test-test), including the coding style;
-2. [sign off](#sign-off) your contribution;
-3. `git push` your commit to your fork of Synapse;
-4. on GitHub, [create the Pull Request](https://docs.github.com/en/github/collaborating-with-issues-and-pull-requests/creating-a-pull-request);

-6. for most contributors, that's all - however, if you are a member of the organization `matrix-org`, on GitHub, please request a review from `matrix.org / Synapse Core`.

+# Picking a database engine
 
-### Installing from source
+Synapse offers two database engines:
+ * [PostgreSQL](https://www.postgresql.org)
+ * [SQLite](https://sqlite.org/)
+
+Almost all installations should opt to use PostgreSQL. Advantages include:
+
+* significant performance improvements due to the superior threading and

+* allowing the DB to be run on separate hardware
+
+For information on how to install and use PostgreSQL, please see
+[docs/postgres.md](docs/postgres.md)

+By default Synapse uses SQLite and in doing so trades performance for convenience.

-Upgrading to v1.32.0
-====================
-
-Removal of old List Accounts Admin API
---------------------------------------
-
-The deprecated v1 "list accounts" admin API (``GET /_synapse/admin/v1/users/<user_id>``) has been removed in this version.
-
-The `v2 list accounts API <https://github.com/matrix-org/synapse/blob/master/docs/admin_api/user_admin_api.rst#list-accounts>`_
-has been available since Synapse 1.7.0 (2019-12-13), and is accessible under ``GET /_synapse/admin/v2/users``.
-
-The deprecation of the old endpoint was announced with Synapse 1.28.0 (released on 2021-02-25).
-
-Upgrading to v1.29.0
-====================
-
-Requirement for X-Forwarded-Proto header
-----------------------------------------
-
-When using Synapse with a reverse proxy (in particular, when using the
-`x_forwarded` option on an HTTP listener), Synapse now expects to receive an
-`X-Forwarded-Proto` header on incoming HTTP requests. If it is not set, Synapse
-will log a warning on each received request.
-
-To avoid the warning, administrators using a reverse proxy should ensure that
-the reverse proxy sets `X-Forwarded-Proto` header to `https` or `http` to
-indicate the protocol used by the client.
-
-Synapse also requires the `Host` header to be preserved.
-
-See the `reverse proxy documentation <docs/reverse_proxy.md>`_, where the
-example configurations have been updated to show how to set these headers.
-
-(Users of `Caddy <https://caddyserver.com/>`_ are unaffected, since we believe it
-sets `X-Forwarded-Proto` by default.)
-
-Upgrading to v1.27.0
-====================
-
-Changes to callback URI for OAuth2 / OpenID Connect and SAML2
--------------------------------------------------------------
-
-This version changes the URI used for callbacks from OAuth2 and SAML2 identity providers:
-
-* If your server is configured for single sign-on via an OpenID Connect or OAuth2 identity
-  provider, you will need to add ``[synapse public baseurl]/_synapse/client/oidc/callback``
-  to the list of permitted "redirect URIs" at the identity provider.
-
-  See `docs/openid.md <docs/openid.md>`_ for more information on setting up OpenID
-  Connect.
-
-* If your server is configured for single sign-on via a SAML2 identity provider, you will
-  need to add ``[synapse public baseurl]/_synapse/client/saml2/authn_response`` as a permitted
-  "ACS location" (also known as "allowed callback URLs") at the identity provider.
-
-  The "Issuer" in the "AuthnRequest" to the SAML2 identity provider is also updated to
-  ``[synapse public baseurl]/_synapse/client/saml2/metadata.xml``. If your SAML2 identity
-  provider uses this property to validate or otherwise identify Synapse, its configuration
-  will need to be updated to use the new URL. Alternatively you could create a new, separate
-  "EntityDescriptor" in your SAML2 identity provider with the new URLs and leave the URLs in
-  the existing "EntityDescriptor" as they were.
-
-Changes to HTML templates
--------------------------
-
-The HTML templates for SSO and email notifications now have `Jinja2's autoescape <https://jinja.palletsprojects.com/en/2.11.x/api/#autoescaping>`_
-enabled for files ending in ``.html``, ``.htm``, and ``.xml``. If you have customised
-these templates and see issues when viewing them you might need to update them.
-It is expected that most configurations will need no changes.
-
-If you have customised the templates *names* for these templates, it is recommended
-to verify they end in ``.html`` to ensure autoescape is enabled.
-
-The above applies to the following templates:
-
-* ``add_threepid.html``
-* ``add_threepid_failure.html``
-* ``add_threepid_success.html``
-* ``notice_expiry.html``
-* ``notice_expiry.html``
-* ``notif_mail.html`` (which, by default, includes ``room.html`` and ``notif.html``)
-* ``password_reset.html``

-====================
-
-Rolling back to v1.25.0 after a failed upgrade
-----------------------------------------------
-
-v1.26.0 includes a lot of large changes. If something problematic occurs, you
-may want to roll-back to a previous version of Synapse. Because v1.26.0 also
-includes a new database schema version, reverting that version is also required
-alongside the generic rollback instructions mentioned above. In short, to roll
-back to v1.25.0 you need to:
-
-1. Stop the server
-2. Decrease the schema version in the database:
-
-   .. code:: sql
-
-      UPDATE schema_version SET version = 58;
-
-3. Delete the ignored users & chain cover data:
-
-   .. code:: sql
-
-      DROP TABLE IF EXISTS ignored_users;
-      UPDATE rooms SET has_auth_chain_index = false;
-
-   For PostgreSQL run:
-
-   .. code:: sql
-
-      TRUNCATE event_auth_chain_links;
-      TRUNCATE event_auth_chains;
-
-   For SQLite run:
-
-   .. code:: sql
-
-      DELETE FROM event_auth_chain_links;
-      DELETE FROM event_auth_chains;
-
-4. Mark the deltas as not run (so they will re-run on upgrade).
-
-   .. code:: sql
-
-      DELETE FROM applied_schema_deltas WHERE version = 59 AND file = "59/01ignored_user.py";
-      DELETE FROM applied_schema_deltas WHERE version = 59 AND file = "59/06chain_cover_index.sql";
-
-5. Downgrade Synapse by following the instructions for your installation method
-   in the "Rolling back to older versions" section above.
-
-Upgrading to v1.25.0
-====================
-
-Last release supporting Python 3.5
-----------------------------------
-
-This is the last release of Synapse which guarantees support with Python 3.5,
-which passed its upstream End of Life date several months ago.
-
-We will attempt to maintain support through March 2021, but without guarantees.
-
-In the future, Synapse will follow upstream schedules for ending support of
-older versions of Python and PostgreSQL. Please upgrade to at least Python 3.6
-and PostgreSQL 9.6 as soon as possible.
-
-Blacklisting IP ranges
-----------------------
-
-Synapse v1.25.0 includes new settings, ``ip_range_blacklist`` and
-``ip_range_whitelist``, for controlling outgoing requests from Synapse for federation,
-identity servers, push, and for checking key validity for third-party invite events.
-The previous setting, ``federation_ip_range_blacklist``, is deprecated. The new
-``ip_range_blacklist`` defaults to private IP ranges if it is not defined.
-
-If you have never customised ``federation_ip_range_blacklist`` it is recommended
-that you remove that setting.
-
-If you have customised ``federation_ip_range_blacklist`` you should update the
-setting name to ``ip_range_blacklist``.
-
-If you have a custom push server that is reached via private IP space you may
-need to customise ``ip_range_blacklist`` or ``ip_range_whitelist``.

-Upgrading to v1.24.0
-====================
-
-Custom OpenID Connect mapping provider breaking change
-------------------------------------------------------
-
-This release allows the OpenID Connect mapping provider to perform normalisation
-of the localpart of the Matrix ID. This allows for the mapping provider to
-specify different algorithms, instead of the [default way](https://matrix.org/docs/spec/appendices#mapping-from-other-character-sets).
-
-If your Synapse configuration uses a custom mapping provider
-(`oidc_config.user_mapping_provider.module` is specified and not equal to
-`synapse.handlers.oidc_handler.JinjaOidcMappingProvider`) then you *must* ensure
-that `map_user_attributes` of the mapping provider performs some normalisation
-of the `localpart` returned. To match previous behaviour you can use the
-`map_username_to_mxid_localpart` function provided by Synapse. An example is
-shown below:
-
-.. code-block:: python
-
-  from synapse.types import map_username_to_mxid_localpart
-
-  class MyMappingProvider:
-      def map_user_attributes(self, userinfo, token):
-          # ... your custom logic ...
-          sso_user_id = ...
-          localpart = map_username_to_mxid_localpart(sso_user_id)
-
-          return {"localpart": localpart}
-
-Removal historical Synapse Admin API
-------------------------------------
-
-Historically, the Synapse Admin API has been accessible under:
-
-* ``/_matrix/client/api/v1/admin``
-* ``/_matrix/client/unstable/admin``
-* ``/_matrix/client/r0/admin``
-* ``/_synapse/admin/v1``
-
-The endpoints with ``/_matrix/client/*`` prefixes have been removed as of v1.24.0.
-The Admin API is now only accessible under:
-
-* ``/_synapse/admin/v1``
-
-The only exception is the `/admin/whois` endpoint, which is
-`also available via the client-server API <https://matrix.org/docs/spec/client_server/r0.6.1#get-matrix-client-r0-admin-whois-userid>`_.
-
-The deprecation of the old endpoints was announced with Synapse 1.20.0 (released
-on 2020-09-22) and makes it easier for homeserver admins to lock down external
-access to the Admin API endpoints.
-
-Upgrading to v1.23.0
-====================
-
-Structured logging configuration breaking changes
--------------------------------------------------
-
-This release deprecates use of the ``structured: true`` logging configuration for
-structured logging. If your logging configuration contains ``structured: true``
-then it should be modified based on the `structured logging documentation
-<https://github.com/matrix-org/synapse/blob/master/docs/structured_logging.md>`_.
-
-The ``structured`` and ``drains`` logging options are now deprecated and should
-be replaced by standard logging configuration of ``handlers`` and ``formatters``.
-
-A future will release of Synapse will make using ``structured: true`` an error.
-
-Upgrading to v1.22.0
-====================
-
-ThirdPartyEventRules breaking changes
--------------------------------------
-
-This release introduces a backwards-incompatible change to modules making use of
-``ThirdPartyEventRules`` in Synapse. If you make use of a module defined under the
-``third_party_event_rules`` config option, please make sure it is updated to handle
-the below change:
-
-The ``http_client`` argument is no longer passed to modules as they are initialised. Instead,
-modules are expected to make use of the ``http_client`` property on the ``ModuleApi`` class.
-Modules are now passed a ``module_api`` argument during initialisation, which is an instance of
-``ModuleApi``. ``ModuleApi`` instances have a ``http_client`` property which acts the same as
-the ``http_client`` argument previously passed to ``ThirdPartyEventRules`` modules.
-
