Released: Jul 2, Reference homeserver for the Matrix decentralised comms protocol. View statistics for this project via Libraries. The basics you need to know to get up and running are:. Synapse is currently in rapid development, but as of version 0. 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. It is intended to showcase the concept of Matrix and let folks see the spec in the context of a codebase and let you run your own homeserver and generally help bootstrap the ecosystem.
In Matrix, every user runs one or more Matrix clients, which connect through to a Matrix homeserver. 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. For support installing or managing Synapse, please join synapse:matrix. We do not use GitHub issues for support requests, only for bug reports and feature requests. The easiest way to try out your new Synapse installation is by connecting to it from a web client.
You will need to change the server you are logging into from matrix. Leave the identity server as the default - see Identity servers. If you prefer to use another client, refer to our client breakdown. If all goes well you should at least be able to log in, create a room, and start sending messages.
By default, registration of new users via Matrix clients is disabled. Your name will take the form of:. Matrix serves raw user generated data in some APIs - specifically the content repository endpoints.
Whilst we have tried to mitigate against possible XSS attacks e. This is particularly true of sharing a matrix webclient and server on the same domain. Please check these instructions as upgrading may require extra steps for some versions of synapse. By default Synapse uses SQLite in and doing so trades performance for convenience. SQLite is only recommended in Synapse for testing purposes or for servers with light workloads. One advantage of doing so is that it means that you can expose the default https port to Matrix clients without needing to run Synapse with root privileges.
They are not where accounts or credentials are stored - these live on home servers. This process is very security-sensitive, as there is obvious risk of spam if it is too easy to sign up for Matrix accounts or harvest 3PID data. You can host your own copy of Sydent, but this will prevent you reaching other users in the Matrix ecosystem via their email address, and prevent them finding you.
To reiterate: the Identity server will only be used if you choose to associate an email address with your account, or send an invite to another user via their email address. If a user has registered an email address to their account using an identity server, they can request a password-reset token via clients such as Riot. Before setting up a development environment for synapse, make sure you have the system dependencies such as the python header files installed - see Installing from source.
To check out a synapse for development, clone the git repo into a working directory of your choice:. Synapse has a number of external dependencies, that are easiest to install using pip and a virtualenv:.
This will run a process of downloading and installing all the needed dependencies into a virtual env. It is able to run Synapse directly from the source tree, so installation of the server is not required.Synapses is now the only class for defining synaptic interactions, it replaces ConnectionSTDPetc.
Defining synaptic models. Accessing synaptic variables. Monitoring synaptic variables. Creating synapses with the generator syntax. Creating multi-synapses. The most simple synapse adding a fixed amount to the target membrane potential on every spike is described as follows:. If the target group is not specified, it is identical to the source group by default. In this case, the constant w is added to variable v. Because v is not defined as a synaptic variable, it is assumed by default that it is a postsynaptic variable, defined in the target NeuronGroup Q.
Note that this does not create synapses see Creating Synapsesonly the synaptic models. To define more complex models, models can be described as string equations, similar to the models specified in NeuronGroup :.
The above specifies a parameter wi. Note that to avoid confusion, synaptic variables cannot have the same name as a pre- or post-synaptic variables. As shown above, variable names that are not referring to a synaptic variable are automatically understood to be post-synaptic variables.
The model follows exactly the same syntax as for NeuronGroup. There can be parameters e. In all cases, synaptic variables are created, one value per synapse. There is normally no need to refer to this variable explicitly, it is used to implement Event-driven updates see below. It is only defined when event-driven equations are used. By default, differential equations are integrated in a clock-driven fashion, as for a NeuronGroup. This is potentially very time consuming, because all synapses are updated at every timestep and Brian will therefore emit a warning.
If you are sure about integrating the equations at every timestep e. To ask Brian 2 to simulate differential equations in an event-driven fashion use the flag event-driven.
A typical example is pre- and postsynaptic traces in STDP:.The Synapse object encapsulates a connection to the Synapse service and is used for building projects, uploading and retrieving data, and recording provenance of data analysis. See synapseclient.
Creates a batch of synapseclient. Column s within a single request. Column objects. Column objects that have been created in Synapse. ProxyStorage: a proxy server that controls access to a storage - secretKey: The encryption key used to sign all pre-signed URLs used to communicate with the proxy. Optional kwargs for ALL types: - banner: The optional banner to show every time a file is uploaded - description: The description to show the user when the user has to choose which upload destination to use.
Create an external S3 file handle for e. Create a storage location in the given parent, either in the given folder or by creating a new folder in that parent with the given name. This will both create a StorageLocationSetting, and a ProjectSetting together, optionally creating a new folder in which to locate it, and optionally enabling this storage location for access via STS.
If enabling an existing folder for STS, it must be empty. The associated files are JSON encoded, so we might retrieve the files from Synapse and load for the second of those rows as shown here:.

Porting Synapse to Python 3
TeamMember objects. Get the details about a Synapse user.Matrix's reference homeserver, Synapse, is written in Python and uses the Twisted networking framework to power its bitslinging across the Internet. The Python version used has been strictly Python 2. Since Twisted and our other upstream dependencies now support the newest version of Python, Python 3, we are now able to finish the jump and port Synapse to use it by default. The port has been done in a backwards compatible way, written in a subset of Python that is usable in both Python 2 and Python 3, meaning your existing Synapse installs still work on Python 2, while preparing us for a Python 3 future.
The Python 3 port has benefits other than just preparing for the End of Life of Python 2. Successive versions of Python 3 have improved the standard library, provided newer and clearer syntax for asynchronous code, added opt-in static typing to reduce bugs, and contained incremental performance and memory management improvements. These features, once Synapse stops supporting Python 2, can then be fully utilised to make Synapse's codebase clearer and more performant.
One bonus that we get immediately, though, is Python 3's memory compaction of Unicode strings. The CPU utilisation has gone down on synchrotron 1 after the Python 3 migration, but not as dramatically as the federation reader. Synchrotron 3 was migrated a few days later. As some extra data-points, my personal HS consumes about MB now at initial start, and grows to approximately MB -- under Python 2 the growth would be near-immediate to roughly 1.
All Posts. Why port? Porting Synapse to Python 3 prepares Synapse for a post-Python 2 world, currently scheduled for After the 1st of January inPython 2 will no longer be supported by the core Python developers and no bugfixes even critical security ones will be issued.
As the security of software depends very much on the runtime and libraries it is running on top of, this means that by then all Python 2 software in use should have moved to Python 3 or other runtimes. Editor's note: If you were wondering how this fits in with Dendrite the next-gen golang homeserver : our plan is to use Synapse as the reference homeserver for all the current work going on with landing a 1.
In order to prove that the 1. It's worth noting that over the last year we've been plugging away solidly improving Synapse in general especially given the increasing number of high-profile deployments out thereso we're committed to getting Synapse to a formal production grade release and supporting it in the long term.
Meanwhile, Dendrite development is still progressing - currently acting as a place to experiment with more radical blue-sky architectural changes, especially in low-footprint or even clientside homeservers. We expect it to catch up with Synapse once 1.
When will the port be released? This will work on installations with and without workers. What's it like in the real world? You can see this demonstrated on matrix. This is on some of the Synchrotrons on matrix. This is on the Synapse master on matrix. We have also noticed some better CPU utilisation: See for the migration of federation reader 1, and for the others. The federation reader is a particular pathological case, where the replacement of lists with iterators internally on Python 3 has given us some big boosts.
Where to from here? Python 2 is still a supported platform for running Synapse for the time being. We plan on ending mainstream support on 1st Aprilwhere upon Python 3. Additionally, we will give notice ahead of time once we are ready to remove Python 2. Although slightly inconvenient, we hope that this gives our users and integrators adequate time to migrate, whilst giving us the flexibility to use modern Python features and make Synapse a better piece of software to help power the Matrix community.
How can I try it? The port is compatible with existing homeservers and configurations, so if you install Synapse inside a Python 3 virtualenv, you can run it from there. Of course, this differs based on your installation method, operating system, and what version of Python 3 you wish to use.

The synapseclient package lets you communicate with the cloud-hosted Synapse service to access data and create shared data analysis projects from within Python scripts or at the interactive Python console. Other Synapse clients exist for RJavaand the web. The Python client can also be used from the command line. The synapseclient package is available from PyPI. It can be installed or upgraded with pip. Note that synapseclient requires Python 3, and if you have both Python 2 and Python 3 installations your system, the pip command associated with Python 3 may be named pip3 to distinguish it from a Python 2 associated command.
Prefixing the pip installation with sudo may be necessary if you are installing Python into a shared system installation of Python. The dependencies on pandas and pysftp are optional.
The Synapse synapseclient. Support for sftp is required for users of SFTP file storage. Both require native libraries to be compiled or installed separately from prebuilt binaries. Source code and development versions are available on Github.
Synapse Python Client API
Installing from source:. You can stay on the master branch to get the latest stable release or check out the develop branch or a tagged revision:. Python 2. Synapse identifiers are used to refer to projects and data which are represented by synapseclient. For example, the entity syn represents a tab-delimited file containing a by 4 matrix. Getting the entity retrieves an object that holds metadata describing the matrix, and also downloads the file to a local cache:.
You can create your own projects and upload your own data sets. Synapse stores entities in a hierarchical or tree structure. Projects are at the top level and must be uniquely named:. Tables can be built up by adding sets of rows that follow a user-defined schema and queried using a SQL-like syntax. Wiki pages can be attached to an Synapse entity i. Text and graphics can be composed in markdown and rendered in the web view of the object.
An evaluation is a Synapse construct useful for building processing pipelines and for scoring predictive modelling and data analysis challenges.
By default, data sets in Synapse are private to your user account, but they can easily be shared with specific users, groups, or the public. There is a companion module called synapseutils that provide higher level functionality such as recursive copying of content, syncing with Synapse and additional query functionality. See: - synapseutils. For more information see the Synapse User Guide. To get information about new versions of the client, see: synapseclient.
Add a code resource that was executed during the activity. See synapseclient. This method tries to be as permissive as possible. If target and optionally targetVersion are specified, create a UsedEntity. If url and optionally name are specified, create a UsedURL.
In case of conflicting settings for wasExecuted both inside an object and with a parameter, the parameter wins.
Represent Synapse Entity annotations as a flat dictionary with the system assigned properties id, etag as object attributes. Defines a column to be used in a table synapseclient.I couldn't be more pleased with Nordic Visitor.
On both my tours with you Iceland and Norway the service was absolutely perfect. I have been travelling for 31 yrs and I have to say the service provided by Nordic Visitor (through Sindre) was exemplary!.
And they went beyond perfect in Norway when I came down with pneumonia. I have never had such good service from a tour company before ever. If not for the fact that I have been to all the other destinations on their list I would have no hesitation in booking with them again. Your company is terrific. Everything was thought of and documentation was great. We loved Iceland We were very impressed with the whole trip. The hotels were great.imglyb: Bridging The Chasm Between ImageJ and NumPy - SciPy 2019 - Philipp Hanslovsky
Travel documents all ready at the train station for us. Really enjoyed the trip and look forward to doing another one in the future. I was just so impressed with everything. From the minute I made my first enquiry, till the point I was dropped off at the airport on my return, I felt that I was important to Nordic Visitor and nothing was too much trouble.
Can I pay particular tribute to Karolina our tour guide. She is an absolute credit to your company. She really went out of her way to ensure we all had a wonderful holiday. She was professional, diligent, so hardworking and we all fell in love with her. Everything about this trip was so easy and Thor did an amazing job at assisting with all aspects, adding and changing our schedule and providing us with all the information necessary for an amazing trip.
Both my girlfriend and I were delighted with every aspect of the trip, from the booking, all the way through to the accommodation, transfers, and activities. Utterly perfect The overall experience exceeded our expectations and was a truly wonderful experience. The husky sled transfer from the airport was amazing. Every trip we did had helpful, happy and informative staff.
