Changes in synapse v0.9.0 (2015-05-07)
======================================
General:
* Add support for using a PostgreSQL database instead of SQLite. See
`docs/postgres.rst`_ for details.
* Add password change and reset APIs. See `Registration`_ in the spec.
* Fix memory leak due to not releasing stale notifiers - SYN-339.
* Fix race in caches that occasionally caused some presence updates to be
dropped - SYN-369.
* Check server name has not changed on restart.
Federation:
* Add key distribution mechanisms for fetching public keys of unavailable
remote home servers. See `Retrieving Server Keys`_ in the spec.
Configuration:
* Add support for multiple config files.
* Add support for dictionaries in config files.
* Remove support for specifying config options on the command line, except
for:
* ``--daemonize`` - Daemonize the home server.
* ``--manhole`` - Turn on the twisted telnet manhole service on the given
port.
* ``--database-path`` - The path to a sqlite database to use.
* ``--verbose`` - The verbosity level.
* ``--log-file`` - File to log to.
* ``--log-config`` - Python logging config file.
* ``--enable-registration`` - Enable registration for new users.
Application services:
* Reliably retry sending of events from Synapse to application services, as per
`Application Services`_ spec.
* Application services can no longer register via the ``/register`` API,
instead their configuration should be saved to a file and listed in the
synapse ``app_service_config_files`` config option. The AS configuration file
has the same format as the old ``/register`` request.

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).
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 to ask us to pull
your changes into our repo
(https://help.github.com/articles/using-pull-requests/)
**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 Jenkins for continuous integration (http://matrix.org/jenkins), and
typically all pull requests get automatically tested Jenkins: if your change breaks the build, Jenkins will yell about it in #matrix-dev:matrix.org so please lurk there and keep an eye open.
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
at https://github.com/matrix-org/synapse/tree/master/docs/code_style.rst.
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.
Attribution
~~~~~~~~~~~
Everyone who contributes anything to Matrix is welcome to be listed in the
AUTHORS.rst file for the project in question. Please feel free to include a
change to AUTHORS.rst in your pull request to list yourself and a short
description of the area(s) you've worked on. Also, we sometimes have swag to
give away to contributors - if you feel that Matrix-branded apparel is missing
from your life, please mail us your shipping address to matrix at matrix.org and we'll try to fix it :)
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
(https://www.kernel.org/doc/Documentation/SubmittingPatches), 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::
Developer Certificate of Origin
Version 1.1
Copyright (C) 2004, 2006 The Linux Foundation and its contributors.
660 York Street, Suite 102,
San Francisco, CA 94110 USA
Everyone is permitted to copy and distribute verbatim copies of this
license document, but changing it is not allowed.
Developer's Certificate of Origin 1.1
By making a contribution to this project, I certify that:
(a) The contribution was created in whole or in part by me and I
have the right to submit it under the open source license
indicated in the file; or
(b) The contribution is based upon previous work that, to the best
of my knowledge, is covered under an appropriate open source
license and I have the right under that license to submit that
work with modifications, whether created in whole or in part
by me, under the same open source license (unless I am
permitted to submit under a different license), as indicated
in the file; or
(c) The contribution was provided directly to me by some other
person who certified (a), (b) or (c) and I have not modified
it.
(d) I understand and agree that this project and the contribution
are public and that a record of the contribution (including all
personal information I submit with it, including my sign-off) is
maintained indefinitely and may be redistributed consistent with
this project or the open source license(s) involved.
If you agree to this for your contribution, then all that's needed is to
include the line in your commit or pull request comment::
Signed-off-by: Your Name <your@email.example.org>
...using your real name; unfortunately pseudonyms and anonymous contributions
can't be accepted. Git makes this trivial - just use the -s flag when you do
``git commit``, having first set ``user.name`` and ``user.email`` git configs
(which you should have done anyway :)
Conclusion
~~~~~~~~~~
That's it! Matrix is a very open and collaborative project as you might expect given our obsession with open communication. If we're going to successfully matrix together all the fragmented communication technologies out there we are reliant on contributions and collaboration from the community to do so. So please get involved - and we hope you have as much fun hacking on Matrix as we do!

This will generate you a config file that you can then customise, but it will
also generate a set of keys for you. These keys will allow your Home Server to
identify itself to other Home Servers, so don't lose or delete them. It would be
wise to back them up somewhere safe. If, for whatever reason, you do need to
change your Home Server's keys, you may find that other Home Servers have the
old key cached. If you update the signing key, you should change the name of the
key in the <server name>.signing.key file (the second word, which by default is
, 'auto') to something different.
By default, registration of new users is disabled. You can either enable
registration in the config (it is then recommended to also set up CAPTCHA), or

Troubleshooting Installation
----------------------------
Using PostgreSQL
================
Synapse requires pip 1.7 or later, so if your OS provides too old a version and
you get errors about ``error: no such option: --process-dependency-links`` you
may need to manually upgrade it::
As of Synapse 0.9, `PostgreSQL <http://www.postgresql.org>`_ is supported as an
alternative to the `SQLite <http://sqlite.org/>`_ database that Synapse has
traditionally used for convenience and simplicity.
$ sudo pip install --upgrade pip
The advantages of Postgres include:
If pip crashes mid-installation for reason (e.g. lost terminal), pip may
refuse to run until you remove the temporary installation directory it
created. To reset the installation::
* significant performance improvements due to the superior threading and
caching model, smarter query optimiser
* allowing the DB to be run on separate hardware
* allowing basic active/backup high-availability with a "hot spare" synapse
pointing at the same DB master, as well as enabling DB replication in
synapse itself.
The only disadvantage is that the code is relatively new as of April 2015 and
may have a few regressions relative to SQLite.
$ rm -rf /tmp/pip_install_matrix
For information on how to install and use PostgreSQL, please see
`docs/postgres.rst <docs/postgres.rst>`_.
pip seems to leak *lots* of memory during installation. For instance, a Linux
host with 512MB of RAM may run out of memory whilst installing Twisted. If this
happens, you will have to individually install the dependencies which are
failing, e.g.::
Running Synapse
===============
$ pip install twisted
To actually run your new homeserver, pick a working directory for Synapse to run
(e.g. ``~/.synapse``), and::
On OSX, if you encounter clang: error: unknown argument: '-mno-fused-madd' you
will need to export CFLAGS=-Qunused-arguments.
$ cd ~/.synapse

Upgrading to v0.x.x
===================
Application services have had a breaking API change in this version.
They can no longer register themselves with a home server using the AS HTTP API. This
decision was made because a compromised application service with free reign to register
any regex in effect grants full read/write access to the home server if a regex of ``.*``
is used. An attack where a compromised AS re-registers itself with ``.*`` was deemed too
big of a security risk to ignore, and so the ability to register with the HS remotely has
been removed.
It has been replaced by specifying a list of application service registrations in
``homeserver.yaml``::
app_service_config_files: ["registration-01.yaml", "registration-02.yaml"]
Where ``registration-01.yaml`` looks like::
url: <String> # e.g. "https://my.application.service.com"
as_token: <String>
hs_token: <String>
sender_localpart: <String> # This is a new field which denotes the user_id localpart when using the AS token

users:

Captcha can be enabled for this home server. This file explains how to do that.
The captcha mechanism used is Google's ReCaptcha. This requires API keys from Google.
Getting keys
------------
Requires a public/private key pair from:
https://developers.google.com/recaptcha/
Setting ReCaptcha Keys
----------------------
The keys are a config option on the home server config. If they are not
visible, you can generate them via --generate-config. Set the following value:
recaptcha_public_key: YOUR_PUBLIC_KEY
recaptcha_private_key: YOUR_PRIVATE_KEY
In addition, you MUST enable captchas via:
enable_registration_captcha: true
Configuring IP used for auth
----------------------------
The ReCaptcha API requires that the IP address of the user who solved the
captcha is sent. If the client is connecting through a proxy or load balancer,
it may be required to use the X-Forwarded-For (XFF) header instead of the origin
IP address. This can be configured as an option on the home server like so:
captcha_ip_origin_is_x_forwarded: true

Registering an Application Service
==================================
The registration of new application services depends on the homeserver used.
In synapse, you need to create a new configuration file for your AS and add it
to the list specified under the ``app_service_config_files`` config
option in your synapse config.
For example:
.. code-block:: yaml
app_service_config_files:
- /home/matrix/.synapse/<your-AS>.yaml
The format of the AS configuration file is as follows:
.. code-block:: yaml
url: <base url of AS>
as_token: <token AS will add to requests to HS>
hs_token: <token HS will ad to requests to AS>
sender_localpart: <localpart of AS user>
namespaces:
users: # List of users we're interested in
- exclusive: <bool>
regex: <regex>
- ...
aliases: [] # List of aliases we're interested in
rooms: [] # List of room ids we're interested in
See the spec_ for further details on how application services work.
.. _spec: https://github.com/matrix-org/matrix-doc/blob/master/specification/25_application_service_api.rst#application-service-api

How to monitor Synapse metrics using Prometheus
===============================================
1: Install prometheus:
Follow instructions at http://prometheus.io/docs/introduction/install/
2: Enable synapse metrics:
Simply setting a (local) port number will enable it. Pick a port.
prometheus itself defaults to 9090, so starting just above that for
locally monitored services seems reasonable. E.g. 9092:
Add to homeserver.yaml
metrics_port: 9092
Restart synapse
3: Check out synapse-prometheus-config
https://github.com/matrix-org/synapse-prometheus-config
4: Add ``synapse.html`` and ``synapse.rules``
The ``.html`` file needs to appear in prometheus's ``consoles`` directory,
and the ``.rules`` file needs to be invoked somewhere in the main config
file. A symlink to each from the git checkout into the prometheus directory
might be easiest to ensure ``git pull`` keeps it updated.
5: Add a prometheus target for synapse
This is easiest if prometheus runs on the same machine as synapse, as it can
then just use localhost::
global: {
rule_file: "synapse.rules"
}
job: {
name: "synapse"
target_group: {
target: "http://localhost:9092/"
}
}
6: Start prometheus::
./prometheus -config.file=prometheus.conf
7: Wait a few seconds for it to start and perform the first scrape,
then visit the console:
http://server-where-prometheus-runs:9090/consoles/synapse.html

Using Postgres
--------------
Set up database
===============
The PostgreSQL database used *must* have the correct encoding set, otherwise
would not be able to store UTF8 strings. To create a database with the correct
encoding use, e.g.::
CREATE DATABASE synapse
ENCODING 'UTF8'
LC_COLLATE='C'
LC_CTYPE='C'
template=template0
OWNER synapse_user;
This would create an appropriate database named ``synapse`` owned by the
``synapse_user`` user (which must already exist).
Set up client
=============
Postgres support depends on the postgres python connector ``psycopg2``. In the
virtual env::
sudo apt-get install libpq-dev
pip install psycopg2
Synapse config
==============
When you are ready to start using PostgreSQL, add the following line to your
config file::
database:
name: psycopg2
args:
user: <user>
password: <pass>
database: <db>
host: <host>
cp_min: 5
cp_max: 10
All key, values in ``args`` are passed to the ``psycopg2.connect(..)``
function, except keys beginning with ``cp_``, which are consumed by the twisted
adbapi connection pool.
Porting from SQLite
===================
Overview
~~~~~~~~
The script ``port_from_sqlite_to_postgres.py`` allows porting an existing
synapse server backed by SQLite to using PostgreSQL. This is done in as a two
phase process:
1. Copy the existing SQLite database to a separate location (while the server
is down) and running the port script against that offline database.
2. Shut down the server. Rerun the port script to port any data that has come
in since taking the first snapshot. Restart server against the PostgreSQL
database.
The port script is designed to be run repeatedly against newer snapshots of the
SQLite database file. This makes it safe to repeat step 1 if there was a delay
between taking the previous snapshot and being ready to do step 2.
It is safe to at any time kill the port script and restart it.
Using the port script
~~~~~~~~~~~~~~~~~~~~~
Firstly, shut down the currently running synapse server and copy its database
file (typically ``homeserver.db``) to another location. Once the copy is
complete, restart synapse. For instance::
./synctl stop
cp homeserver.db homeserver.db.snapshot
./synctl start
Assuming your database config file (as described in the section *Synapse
config*) is named ``database_config.yaml`` and the SQLite snapshot is at
``homeserver.db.snapshot`` then simply run::
python scripts/port_from_sqlite_to_postgres.py \
--sqlite-database homeserver.db.snapshot \
--postgres-config database_config.yaml
The flag ``--curses`` displays a coloured curses progress UI.
If the script took a long time to complete, or time has otherwise passed since
the original snapshot was taken, repeat the previous steps with a newer
snapshot.
To complete the conversion shut down the synapse server and run the port
script one last time, e.g. if the SQLite database is at ``homeserver.db``
run::
python scripts/port_from_sqlite_to_postgres.py \
--sqlite-database homeserver.db \
--postgres-config database_config.yaml
Once that has completed, change the synapse config to point at the PostgreSQL
database configuration file using the ``database_config`` parameter (see
`Synapse Config`_) and restart synapse. Synapse should now be running against
PostgreSQL.

This module controls the reliability for application service transactions.
The nominal flow through this module looks like:
__________
1---ASa[e]-->| Service |--> Queue ASa[f]
2----ASb[e]->| Queuer |
3--ASa[f]--->|__________|-----------+ ASa[e], ASb[e]
V
-````````- +------------+
|````````|<--StoreTxn-|Transaction |
|Database| | Controller |---> SEND TO AS
`--------` +------------+
What happens on SEND TO AS depends on the state of the Application Service:
- If the AS is marked as DOWN, do nothing.
- If the AS is marked as UP, send the transaction.
* SUCCESS : Increment where the AS is up to txn-wise and nuke the txn
contents from the db.
* FAILURE : Marked AS as DOWN and start Recoverer.
Recoverer attempts to recover ASes who have died. The flow for this looks like:
,--------------------- backoff++ --------------.
V |
START ---> Wait exp ------> Get oldest txn ID from ----> FAILURE
backoff DB and try to send it
^ |___________
Mark AS as | V
UP & quit +---------- YES SUCCESS
| | |
NO <--- Have more txns? <------ Mark txn success & nuke <-+
from db; incr AS pos.
Reset backoff.
This is all tied together by the AppServiceScheduler which DIs the required
components.
