changelog

Instead of sending state events as we go, we instead calculate all state
events to send and store them in a dict (ordered since Python 3.7) and
then send them all at once in the end.

This has no performance benefit whatsoever, but I find this clearer to
reason about. My personal use case is eventually placing another layer
of "custom room preset" state on top, which would be easier to do with a
state map, instead of the previous code which sent state into the room
as it went along.

If we do eventually send all new room state simultaneously to speed up
local room creation, I believe this would be an easier starting point.

-Synapse 1.71.0 (2022-11-08)
-===========================
-
-Please note that, as announced in the release notes for Synapse 1.69.0, legacy Prometheus metric names are now disabled by default.
-They will be removed altogether in Synapse 1.73.0.
-If not already done, server administrators should update their dashboards and alerting rules to avoid using the deprecated metric names.
-See the [upgrade notes](https://matrix-org.github.io/synapse/v1.71/upgrade.html#upgrading-to-v1710) for more details.
-
-**Note:** in line with our [deprecation policy](https://matrix-org.github.io/synapse/latest/deprecation_policy.html) for platform dependencies, this will be the last release to support PostgreSQL 10, which reaches upstream end-of-life on November 10th, 2022. Future releases of Synapse will require PostgreSQL 11+.
-
-No significant changes since 1.71.0rc2.

-for workers. Server admins should use Redis instead. See the [upgrade
-notes](https://matrix-org.github.io/synapse/v1.67/upgrade.html#upgrading-to-v1670).
-
-The minimum version of `poetry` supported for managing source checkouts is now
-1.2.0.
-
-**Notice:** from the next major release (1.68.0) installing Synapse from a source
-checkout will require a recent Rust compiler. Those using packages or
-`pip install matrix-synapse` will not be affected. See the [upgrade
-notes](https://matrix-org.github.io/synapse/v1.67/upgrade.html#upgrading-to-v1670).
-
-**Notice:** from the next major release (1.68.0), running Synapse with a SQLite
-database will require SQLite version 3.27.0 or higher. (The [current minimum
- version is SQLite 3.22.0](https://github.com/matrix-org/synapse/blob/release-v1.67/synapse/storage/engines/sqlite.py#L69-L78).)

-Bugfixes
---------
-
-- Fix a bug introduced in Synapse 1.13 where the [List Rooms admin API](https://matrix-org.github.io/synapse/develop/admin_api/rooms.html#list-room-api) would return integers instead of booleans for the `federatable` and `public` fields when using a Sqlite database.

-Synapse 1.66.0 (2022-08-31)
-===========================
-
-No significant changes since 1.66.0rc2.
-
-This release removes the ability for homeservers to delegate email ownership
-verification and password reset confirmation to identity servers. This removal
-was originally planned for Synapse 1.64, but was later deferred until now. See
-the [upgrade notes](https://matrix-org.github.io/synapse/v1.66/upgrade.html#upgrading-to-v1660) for more details.
-
-Deployments with multiple workers should note that the direct TCP replication
-configuration was deprecated in Synapse 1.18.0 and will be removed in Synapse
-v1.67.0. In particular, the TCP `replication` [listener](https://matrix-org.github.io/synapse/v1.66/usage/configuration/config_documentation.html#listeners)
-type (not to be confused with the `replication` resource on the `http` listener
-type) and the `worker_replication_port` config option will be removed .
-
-To migrate to Redis, add the [`redis` config](https://matrix-org.github.io/synapse/v1.66/workers.html#shared-configuration),
-then remove the TCP `replication` listener from config of the master and
-`worker_replication_port` from worker config. Note that a HTTP listener with a
-`replication` resource is still required. See the
-[worker documentation](https://matrix-org.github.io/synapse/v1.66/workers.html)
-for more details.

-* [GHSA-jhjh-776m-4765](https://github.com/matrix-org/synapse/security/advisories/GHSA-jhjh-776m-4765) / [CVE-2022-31152](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-31152)
-
-  Synapse instances prior to 1.62.0 did not implement the Matrix [event authorization rules](https://spec.matrix.org/v1.3/rooms/v10/#authorization-rules) correctly. An attacker could craft events which would be accepted by Synapse but not a spec-conformant server, potentially causing divergence in the room state between servers.

 =========================================================================
 
-Synapse is an open-source `Matrix <https://matrix.org/>`_ homeserver written and
-maintained by the Matrix.org Foundation. We began rapid development in 2014,
-reaching v1.0.0 in 2019. Development on Synapse and the Matrix protocol itself continues
-in earnest today.
-
-Briefly, Matrix is an open standard for communications on the internet, supporting
-federation, encryption and VoIP. Matrix.org has more to say about the `goals of the
-Matrix project <https://matrix.org/docs/guides/introduction>`_, and the `formal specification

-Installing and configuration
-============================
+Introduction
+============
 
-The Synapse documentation describes `how to install Synapse <https://matrix-org.github.io/synapse/latest/setup/installation.html>`_. We recommend using
-`Docker images <https://matrix-org.github.io/synapse/latest/setup/installation.html#docker-images-and-ansible-playbooks>`_ or `Debian packages from Matrix.org
-<https://matrix-org.github.io/synapse/latest/setup/installation.html#matrixorg-packages>`_.
+Matrix is an ambitious new ecosystem for open federated Instant Messaging and
+VoIP.  The basics you need to know to get up and running are:
+
+- Everything in Matrix happens in a room.  Rooms are distributed and do not
+  exist on any single server.  Rooms can be located using convenience aliases
+  like ``#matrix:matrix.org`` or ``#test:localhost:8448``.
+
+- Matrix user IDs look like ``@matthew:matrix.org`` (although in the future
+  you will normally refer to yourself and others using a third party identifier
+  (3PID): email address, phone number, etc rather than manipulating Matrix user IDs)
+
+The overall architecture is::
+
+      client <----> homeserver <=====================> homeserver <----> client
+             https://somewhere.org/_matrix      https://elsewhere.net/_matrix
+
+``#matrix:matrix.org`` is the official support room for Matrix, and can be
+accessed by any client from https://matrix.org/docs/projects/try-matrix-now.html or
+via IRC bridge at irc://irc.libera.chat/matrix.
+
+Synapse is currently in rapid development, but as of version 0.5 we believe it
+is sufficiently stable to be run as an internet-facing service for real usage!
+
+About Matrix
+============
+
+Matrix specifies a set of pragmatic RESTful HTTP JSON APIs as an open standard,
+which handle:
+
+- Creating and managing fully distributed chat rooms with no
+  single points of control or failure
+- Eventually-consistent cryptographically secure synchronisation of room
+  state across a global open network of federated servers and services
+- Sending and receiving extensible messages in a room with (optional)
+  end-to-end encryption
+- Inviting, joining, leaving, kicking, banning room members
+- Managing user accounts (registration, login, logout)
+- Using 3rd Party IDs (3PIDs) such as email addresses, phone numbers,
+  Facebook accounts to authenticate, identify and discover users on Matrix.
+- Placing 1:1 VoIP and Video calls
+
+These APIs are intended to be implemented on a wide range of servers, services
+and clients, letting developers build messaging and VoIP functionality on top
+of the entirely open Matrix ecosystem rather than using closed or proprietary
+solutions. The hope is for Matrix to act as the building blocks for a new
+generation of fully open and interoperable messaging and VoIP apps for the
+internet.
+
+Synapse is a Matrix "homeserver" implementation developed by the matrix.org core
+team, written in Python 3/Twisted.
+
+In Matrix, every user runs one or more Matrix clients, which connect through to
+a Matrix homeserver. The homeserver stores all their personal chat history and
+user account information - much as a mail client connects through to an
+IMAP/SMTP server. Just like email, you can either run your own Matrix
+homeserver and control and own your own communications and history or use one
+hosted by someone else (e.g. matrix.org) - there is no single point of control
+or mandatory service provider in Matrix, unlike WhatsApp, Facebook, Hangouts,
+etc.
+
+We'd like to invite you to join #matrix:matrix.org (via
+https://matrix.org/docs/projects/try-matrix-now.html), run a homeserver, take a look
+at the `Matrix spec <https://matrix.org/docs/spec>`_, and experiment with the
+`APIs <https://matrix.org/docs/api>`_ and `Client SDKs
+<https://matrix.org/docs/projects/try-matrix-now.html#client-sdks>`_.
+
+Thanks for using Matrix!

+Synapse Installation
+====================
 
 .. _federation:
 
-Synapse has a variety of `config options
-<https://matrix-org.github.io/synapse/latest/usage/configuration/config_documentation.html>`_
-which can be used to customise its behaviour after installation.
-There are additional details on how to `configure Synapse for federation here
-<https://matrix-org.github.io/synapse/latest/federate.html>`_.
-
-.. _reverse-proxy:
-
-Using a reverse proxy with Synapse
-----------------------------------
-
-It is recommended to put a reverse proxy such as
-`nginx <https://nginx.org/en/docs/http/ngx_http_proxy_module.html>`_,
-`Apache <https://httpd.apache.org/docs/current/mod/mod_proxy_http.html>`_,
-`Caddy <https://caddyserver.com/docs/quick-starts/reverse-proxy>`_,
-`HAProxy <https://www.haproxy.org/>`_ or
-`relayd <https://man.openbsd.org/relayd.8>`_ in front of Synapse. One advantage of
-doing so is that it means that you can expose the default https port (443) to
-Matrix clients without needing to run Synapse with root privileges.
-For information on configuring one, see `the reverse proxy docs
-<https://matrix-org.github.io/synapse/latest/reverse_proxy.html>`_.
-
-Upgrading an existing Synapse
------------------------------
-
-The instructions for upgrading Synapse are in `the upgrade notes`_.
-Please check these instructions as upgrading may require extra steps for some
-versions of Synapse.
-
-.. _the upgrade notes: https://matrix-org.github.io/synapse/develop/upgrade.html

+  `Installation Instructions <https://matrix-org.github.io/synapse/latest/setup/installation.html>`_.
+* For specific details on how to configure Synapse for federation see `docs/federate.md <docs/federate.md>`_
 
 
-Platform dependencies
----------------------
+Connecting to Synapse from a client
+===================================
 
-Synapse uses a number of platform dependencies such as Python and PostgreSQL,
-and aims to follow supported upstream versions. See the
-`deprecation policy <https://matrix-org.github.io/synapse/latest/deprecation_policy.html>`_
-for more details.
+The easiest way to try out your new Synapse installation is by connecting to it
+from a web client.
 
+Unless you are running a test instance of Synapse on your local machine, in
+general, you will need to enable TLS support before you can successfully
+connect from a client: see
+`TLS certificates <https://matrix-org.github.io/synapse/latest/setup/installation.html#tls-certificates>`_.
+
+An easy way to get started is to login or register via Element at
+https://app.element.io/#/login or https://app.element.io/#/register respectively.
+You will need to change the server you are logging into from ``matrix.org``
+and instead specify a Homeserver URL of ``https://<server_name>:8448``
+(or just ``https://<server_name>`` if you are using a reverse proxy).
+If you prefer to use another client, refer to our
+`client breakdown <https://matrix.org/docs/projects/clients-matrix>`_.
+
+If all goes well you should at least be able to log in, create a room, and
+start sending messages.
+
+.. _`client-user-reg`:
+
+Registering a new user from a client
+------------------------------------
+
+By default, registration of new users via Matrix clients is disabled. To enable
+it, specify ``enable_registration: true`` in ``homeserver.yaml``. (It is then
+recommended to also set up CAPTCHA - see `<docs/CAPTCHA_SETUP.md>`_.)
+
+Once ``enable_registration`` is set to ``true``, it is possible to register a
+user via a Matrix client.
+
+Your new user name will be formed partly from the ``server_name``, and partly
+from a localpart you specify when you create the account. Your name will take
+the form of::
+
+    @localpart:my.domain.name
+
+(pronounced "at localpart on my dot domain dot name").
+
+As when logging in, you will need to specify a "Custom server".  Specify your
+desired ``localpart`` in the 'User name' box.

 `#synapse-dev:matrix.org <https://matrix.to/#/#synapse-dev:matrix.org>`_, featuring real humans!
 
 
+Quick start
+-----------
+
+Before setting up a development environment for synapse, make sure you have the
+system dependencies (such as the python header files) installed - see
+`Platform-specific prerequisites <https://matrix-org.github.io/synapse/latest/setup/installation.html#platform-specific-prerequisites>`_.
+
+To check out a synapse for development, clone the git repo into a working
+directory of your choice::
+
+    git clone https://github.com/matrix-org/synapse.git
+    cd synapse
+
+Synapse has a number of external dependencies. We maintain a fixed development
+environment using `Poetry <https://python-poetry.org/>`_. First, install poetry. We recommend::
+
+    pip install --user pipx
+    pipx install poetry
+
+as described `here <https://python-poetry.org/docs/#installing-with-pipx>`_.
+(See `poetry's installation docs <https://python-poetry.org/docs/#installation>`_
+for other installation methods.) Then ask poetry to create a virtual environment
+from the project and install Synapse's dependencies::
+
+    poetry install --extras "all test"
+
+This will run a process of downloading and installing all the needed
+dependencies into a virtual env.
+
+We recommend using the demo which starts 3 federated instances running on ports `8080` - `8082`::
+
+    poetry run ./demo/start.sh
+
+(to stop, you can use ``poetry run ./demo/stop.sh``)
+
+See the `demo documentation <https://matrix-org.github.io/synapse/develop/development/demo.html>`_
+for more information.
+
+If you just want to start a single instance of the app and run it directly::
+
+    # Create the homeserver.yaml config once
+    poetry run synapse_homeserver \
+      --server-name my.domain.name \
+      --config-path homeserver.yaml \
+      --generate-config \
+      --report-stats=[yes|no]
+
+    # Start the app
+    poetry run synapse_homeserver --config-path homeserver.yaml
+
+
+Running the unit tests
+----------------------
+
+After getting up and running, you may wish to run Synapse's unit tests to
+check that everything is installed correctly::
+
+    poetry run trial tests
+
+This should end with a 'PASSED' result (note that exact numbers will
+differ)::
+
+    Ran 1337 tests in 716.064s
+
+    PASSED (skips=15, successes=1322)
+
+For more tips on running the unit tests, like running a specific test or
+to see the logging output, see the `CONTRIBUTING doc <CONTRIBUTING.md#run-the-unit-tests>`_.
+
+
+Running the Integration Tests
+-----------------------------
+
+Synapse is accompanied by `SyTest <https://github.com/matrix-org/sytest>`_,
+a Matrix homeserver integration testing suite, which uses HTTP requests to
+access the API as a Matrix client would. It is able to run Synapse directly from
+the source tree, so installation of the server is not required.
+
+Testing with SyTest is recommended for verifying that changes related to the
+Client-Server API are functioning correctly. See the `SyTest installation
+instructions <https://github.com/matrix-org/sytest#installing>`_ for details.
+
+
+Platform dependencies
+=====================
+
+Synapse uses a number of platform dependencies such as Python and PostgreSQL,
+and aims to follow supported upstream versions. See the
+`<docs/deprecation_policy.md>`_ document for more details.

+===============
+
+Need help? Join our community support room on Matrix:
+`#synapse:matrix.org <https://matrix.to/#/#synapse:matrix.org>`_
+
+Running out of File Handles
+---------------------------
+
+If synapse runs out of file handles, it typically fails badly - live-locking
+at 100% CPU, and/or failing to accept new TCP connections (blocking the
+connecting client).  Matrix currently can legitimately use a lot of file handles,
+thanks to busy rooms like #matrix:matrix.org containing hundreds of participating
+servers.  The first time a server talks in a room it will try to connect
+simultaneously to all participating servers, which could exhaust the available
+file descriptors between DNS queries & HTTPS sockets, especially if DNS is slow
+to respond. (We need to improve the routing algorithm used to be better than
+full mesh, but as of March 2019 this hasn't happened yet).
+
+If you hit this failure mode, we recommend increasing the maximum number of
+open file handles to be at least 4096 (assuming a default of 1024 or 256).
+This is typically done by editing ``/etc/security/limits.conf``
+
+Separately, Synapse may leak file handles if inbound HTTP requests get stuck
+during processing - e.g. blocked behind a lock or talking to a remote server etc.
+This is best diagnosed by matching up the 'Received request' and 'Processed request'
+log lines and looking for any 'Processed request' lines which take more than
+a few seconds to execute. Please let us know at #synapse:matrix.org if
+you see this failure mode so we can help debug it, however.
+
+Help!! Synapse is slow and eats all my RAM/CPU!
+-----------------------------------------------
+
+First, ensure you are running the latest version of Synapse, using Python 3
+with a PostgreSQL database.
+
+Synapse's architecture is quite RAM hungry currently - we deliberately
+cache a lot of recent room data and metadata in RAM in order to speed up
+common requests. We'll improve this in the future, but for now the easiest
+way to either reduce the RAM usage (at the risk of slowing things down)
+is to set the almost-undocumented ``SYNAPSE_CACHE_FACTOR`` environment
+variable. The default is 0.5, which can be decreased to reduce RAM usage
+in memory constrained enviroments, or increased if performance starts to
+degrade.
+
+However, degraded performance due to a low cache factor, common on
+machines with slow disks, often leads to explosions in memory use due
+backlogged requests. In this case, reducing the cache factor will make
+things worse. Instead, try increasing it drastically. 2.0 is a good
+starting value.
+
+Using `libjemalloc <http://jemalloc.net/>`_ can also yield a significant
+improvement in overall memory use, and especially in terms of giving back
+RAM to the OS. To use it, the library must simply be put in the
+LD_PRELOAD environment variable when launching Synapse. On Debian, this
+can be done by installing the ``libjemalloc1`` package and adding this
+line to ``/etc/default/matrix-synapse``::
+
+    LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libjemalloc.so.1
+
+This can make a significant difference on Python 2.7 - it's unclear how
+much of an improvement it provides on Python 3.x.
+
+If you're encountering high CPU use by the Synapse process itself, you
+may be affected by a bug with presence tracking that leads to a
+massive excess of outgoing federation requests (see `discussion
+<https://github.com/matrix-org/synapse/issues/3971>`_). If metrics
+indicate that your server is also issuing far more outgoing federation
+requests than can be accounted for by your users' activity, this is a
+likely cause. The misbehavior can be worked around by setting
+the following in the Synapse config file:
+
+.. code-block:: yaml
+
+   presence:
+       enabled: false
+
+People can't accept room invitations from me
+--------------------------------------------
+
+The typical failure mode here is that you send an invitation to someone
+to join a room or direct chat, but when they go to accept it, they get an
+error (typically along the lines of "Invalid signature"). They might see
+something like the following in their logs::
+
+    2019-09-11 19:32:04,271 - synapse.federation.transport.server - 288 - WARNING - GET-11752 - authenticate_request failed: 401: Invalid signature for server <server> with key ed25519:a_EqML: Unable to verify signature for <server>
+
+This is normally caused by a misconfiguration in your reverse-proxy. See
+`<docs/reverse_proxy.md>`_ and double-check that your settings are correct.
