Pre-disclosure: Upcoming critical security fix for Synapse

05.09.2018 00:00 — Security Matthew Hodgson

Hi all,

During the ongoing work to finalise a stable release of Matrix's Server-Server federation API, we've been doing a full audit of Synapse's implementation and have identified a serious vulnerability which we are going to release a security update to address (Synapse 0.33.3.1) on Thursday Sept 6th 2018 at 12:00 UTC.

We are coordinating with package maintainers to ensure that patched versions of packages will be available at that time - meanwhile, if you run your own Synapse, please be prepared to upgrade as soon as the patched versions are released.  All previous versions of Synapse are affected, so everyone will want to upgrade.

Thank you for your time, patience and understanding while we resolve the issue,

Recent matrix.org website improvements

05.09.2018 00:00 — General Ben Parsons

Recently I've been working to improve some of the content on the matrix.org website.

Firstly the FAQ now has updated content and a more presentable menu.

We have a Guides Index, which includes a clarified guide list, plus links to off-site contributions from the community. It's possible to click "recommend" on these items if you've had a good experience with them. If you have documentation or guides you'd like to see added to the list, contact me on Matrix or make a pull request on the site repo.

Finally, as part of a programme to improve visibility on projects in the Matrix ecosystem, we are introducing the "Matrix Clients Matrix". This is a list of some of the most popular current Matrix clients in the ecosystem today, and should shed some light on current feature statuses! The list is not exhaustive, and if you would like to see your client project included, please contact me at the same address, or come chat in the Matrix Client Developers community room.

Matrix Spec Update August 2018

03.09.2018 00:00 — Tech Matthew Hodgson

Introducing Client Server API 0.4, and the first ever stable IS, AS and Push APIs spec releases!

Hi folks,

As many know, we've been on a massive sprint to improve the spec - both fixing omissions where features have been implemented in the reference servers but were never formalised in the spec, and fixing bugs where the spec has thinkos which stop us from being able to ratify it as stable and thus fit for purpose .

In practice, our target has been to cut stable releases of all the primary Matrix APIs by the end of August - effectively declaring Matrix out of beta, at least at the specification level.  For context: historically only one API has ever been released as stable - the Client Server API, which was the result of a similar sprint back in Jan 2016. This means that the Server Server (SS) API, Identity Service (IS) API, Application Service (AS) API and Push Gateway API have never had an official stable release - which has obviously been problematic for those implementing them.

However, as of the end of Friday Aug 31, we're proud to announce the first ever stable releases of the IS, AS and Push APIs!

To the best of our knowledge, these API specs are now complete and accurately describe all the current behaviour implemented in the reference implementations (sydent, synapse and sygnal) and are fit for purpose. Any deviation from the spec in the reference implementations should probably be considered a bug in the impl. All changes take the form of filling in spec omissions and adding clarifications to the existing behaviour in order to get things to the point that an independent party can implement these APIs without having to refer to anything other than the spec.

This is the result of a lot of work which spans the whole Spec Core Team, but has been particularly driven by TravisR, who has taken the lead on this whole mission to improve the spec.  Huge thanks are due to Travis for his work here, and also massive thanks to everyone who has suffered endured reviewed his PRs and contributed to the releases.  The spec is looking unrecognisably better for it - and Matrix 1.0 is feeling closer than ever!

Alongside the work on the IS/AS/Push APIs, there has also been a massive attempt to plug all the spec omissions in the Client Server API.  Historically the CS API releases have missed some of the newer APIs (and of course always miss the ones which postdate a given release), but we've released the APIs which /have/ been specified as stable in order to declare them stable.  However, in this release we've tried to go through and fill in as many remaining gaps as possible.

The result is the release of Client Server API version 0.4. This is a huge update - increasing the size of the CS API by ~40%. The biggest new stuff includes fully formalising support for end-to-end encryption (thanks to Zil0!), versioning for rooms (so we can upgrade rooms to new versions of the protocol), synchronised read markers, user directories, server ACLs, MSISDN 3rd party ids, and .well-known server discovery (not that it's widely used yet), but for the full picture, best bet is to look at the changelog (now managed by towncrier!).  It's probably fair to say that the CS API is growing alarmingly large at this point - Chrome says that it'd be 223 A4 pages if printed. Our solution to this will be to refactor it somehow (and perhaps switch to a more compact representation of the contents).

Some things got deliberately missed from the CS 0.4 release: particularly membership Lazy Loading (because we're still testing it out and haven't released it properly in the wild yet), the various GDPR-specific APIs (because they may evolve a bit as we refine them since the original launch), finalising ID grammars in the overall spec (because this is surprisingly hard and subtle and we don't want to rush it) and finally Communities (aka Groups), as they are still somewhat in flux.

Meanwhile, on the Server to Server API, there has also been a massive amount of work.  Since the beginning of July it's tripled in size as we've filled in the gaps, over the course of >200 commits (>150 of which from Travis).  If you take a look at the current snapshot it's pretty unrecognisable from the historical draft; with the main changes being:

  • Adding the new State Resolution algorithm to address flaws in the original one.  This has been where much of our time has gone - see MSC1442 for full details.  Adopting the new algorithm requires rooms to be recreated; we'll write more about this in the near future when we actually roll it out.
  • Adding room versioning so we can upgrade to the new State Resolution algorithm.
  • Everything is now properly expressed as Swagger (OpenAPI), just like the CS API
  • Adding all the details for E2E encryption (including dependencies like to-device messaging and device-list synchronisation)
  • Improvements in specifying how to authorize inbound events over federation
  • Document federation APIs such as /event_auth and /query_auth and /get_missing_events
  • Document 3rd party invites over federation
  • Document the /user/* federation endpoints
  • Document Server ACLs
  • Document read receipts over federation
  • Document presence over federation
  • Document typing notifications over federation
  • Document content repository over federation
  • Document room directory over federation
  • ...and many many other minor bug fixes, omission fixes, and restructuring for coherency - see https://github.com/matrix-org/matrix-doc/issues/1464 for an even longer list :)
However, we haven't finished it all: despite our best efforts we're running slightly past the original target of Aug 31.  The current state of play for the r0 release overall (in terms of pending issues) is: ...and you can see the full breakdown over at the public Github project dashboard.

The main stuff we still have remaining on the Server/Server API at this point is:

  • Better specifying how we validate inbound events. See MSC1646 for details & progress.
  • Switching event IDs to be hashes. See MSC1640 for details and progress.
  • Various other remaining security considerations (e.g. how to handle malicious auth events in the DAG; how to better handle DoS situations).
  • Merging in the changes to authoring m.room.power_levels (as per MSC1304)
  • Formally specifying the remaining identifiers which lack a formal grammar - MSC1597 and particularly room aliases ( MSC1608)
The plan here is to continue speccing and implementing these at top priority (with Travis continuing to work fulltime on spec work), and we'll obviously keep you up-to-date on progress.  Some of the changes here (e.g. event IDs) are quite major and we definitely want to implement them before speccing them, so we're just going to have to keep going as fast as we can. Needless to say we want to cut an r0 of the S2S API alongside the others asap and declare Matrix out of beta (at least at the spec level :)

In terms of visualising progress on this spec mission it's interesting to look at the rate at which we've been closing PRs: this graph shows the total number of PRs which are in state ‘open' or ‘closed' on any given day:

...which clearly shows the original sprint to get the r0 of the CS API out the door at the end 2015, and then a more leisurely pace until the beginning of July 2018 since which the pace has picked up massively.  Other ways of looking at include the number of open issues...

...or indeed the number of commits per week…

...or the overall Github Project activity for August.  (It's impressive to see Zil0 sneaking in there on second place on the commit count, thanks to all his GSoC work documenting E2E encryption in the spec as part of implementing it in matrix-python-sdk!)

Anyway, enough numerology.  It's worth noting that all of the dev for r0 has generally followed the proposed Open Governance Model for Matrix, with the core spec team made up of both historical core team folk (erik, richvdh, dave & matthew), new core team folk (uhoreg & travis) and community folk (kitsune, anoa & mujx) working together to review and approve the changes - and we've been doing MSCs (albeit with an accelerated pace) for anything which we feel requires input from the wider community.  Once the Server/Server r0 release is out the door we'll be finalising the open governance model and switching to a slightly more measured (but productive!) model of spec development as outlined there.

Meanwhile, Matrix 1.0 gets ever closer.  With (almost) all this spec mission done, our plan is to focus more on improving the reference implementations - particularly performance in Synapse,  UX in matrix-{'{'}react,ios,android{'}'}-sdk as used by Riot (especially for E2E encryption), and then declare a 1.0 and get back to implementing new features (particularly Editable Messages and Reactions) at last.

We'd like to thank everyone for your patience whilst we've been playing catch up on the spec, and hope you agree it's been worth the effort :)

Matthew & the core spec team.

This Week in Matrix 2018-08-31

01.09.2018 00:00 — This Week in Matrix Ben Parsons

The Spec

As many know, we've been aiming for the end of August to cut the first ever stable releases of the remaining APIs in the spec which have up to now been marked unstable - i.e. providing a snapshot of the spec which correctly matches the reference implementations (other than implementation bugs) and which can be used in isolation to develop production grade implementations of clients, servers, etc without need to reference any other implementations. There's been a massive sprint to pull this together, and as of the time of writing there are still PRs and commits landing every few minutes.  We'll post a full update on our progress on Monday; meanwhile you can see a sneak peek over at the August 2018 r0 project board.

Spec work has completely precluded any other backend dev this week.

Half-Shot, gone but not really gone

This week we say farewell to Half-Shot, who has been working fulltime on bridges over the summer. He has managed the matrix.org bridges largely single-handedly, with a big focus on the often-volatile IRC bridge(s).

Bridges

matrix-appservice-irc 0.11.0

It's a big deal, and it's rolling out to IRC networks this week. Half-Shot released matrix-appservice-irc 0.11.0, with the following included:

New features & improvements:

  • Cache modes internally
  • Replace nicks with user pill mentions
  • Kick users if we fail to create an IRC client for them on join (aka ILINE kicks)
  • SASL support
  • Add err_nononreg so we can announce PMs that failed
  • Formatting of replies
Bug Fixes:
  • Fix invalidchar nick
  • Don't answer any msgtypes other than text in an admin room.
  • Fix provisoner leaving users on unlink
  • Fixed a bug where content of events the bridge hadn't cached were not being used in replies.
  • We were calling authedRequest but the request was not mocked out.
  • There was a bug involving intents in m-a-b so it was bumped
Metrics:
  • Metrics for MatrixHandler - Iline Kicks
  • Idle connection metrics
  • QueuePool.waitingItems should use it's internal queue size
Misc:
  • Section out tests, linting and coverage into separate stages for Travis

WhatsApp

tulir has been working on mautrix-whatsapp bridge.

now bridges a lot more stuff, such as formatting, media and replies. I'm also almost done with desegregating users so that Matrix users join the same group chat portals rather than everyone having their own portal to the same chat

Zulip chat, bridged by Zulip

Matthew discovered there is a Matrix-Zulip bridge on the Zulip side. So if you're running a Zulip server (for some reason), and want to bridge with Matrix check out the integration docs here.

IRC Connection Tracker

Half-Shot created a new component to enhance the reliability of IRC-Matrix bridging:

IRC Connection Tracker is a thing now. It's a project to separate out the IRC connections from the appservice so the two can be run independently, so that restarting the appservice doesn't affect the IRC connections. It's hopefully going to allow bridge stuff to run faster when it's done.

This project is still really early stage. You can take a look at the Proposal document here.

Clients

Nheko 0.5.4

Not technically this week, but Nheko 0.5.4 was recently released

  • The settings page now includes the device id & device fingerprint (thanks @valkum )
  • The Polish translation has been updated (thanks @m4sk1n )
Get the latest builds of Nheko from bintray.

Fractal

Alexandre Franke and the GNOME crew have been working on Fractal, gearing up for their upcoming 3.30 release.

Fractal 3.29.92 got released and we are freezing strings to give GNOME translators a bit of time to complete translations for 3.30 next week. Latest developments include tweaks for the title bar, misc bug fixes, a new presentation for uploaded files (that are not images, those are still displayed inline) with buttons to download or open them. Development builds are now parallel installable for easier testing and CI has been improved.

Seaglass

neilalexander:

Seaglass now has some early support for inline images and attachments, and supports Quick Look. Also handles emotes and notices better. It also has version numbers now, various other little fixes and Aaron Raimist has been working on auto-update support.

Version numbers! Now when you go to download the tarball from bintray, you can see what's going on!

There's also been some work on supporting dark mode on Mojave (which looks particularly sexy) and even Touch Bar support!

This is a tiny webextension to forward matrix.to links to an open Riot tab.

Really useful if you often click matrix.to links and find yourself needing to URL-hack to get to where you need to be.

That's all for now

We're going to shift this week's Matrix Live to Monday, alongside the upcoming blog post on the spec release progress. Have a good weekend!

So long Half-Shot, thanks for all the bridges

31.08.2018 00:00 — Thoughts Ben Parsons

Thank you to Half-Shot for all your work on Bridges over the last months and beyond. Today is your last day, but I'm sure we'll see you again before long. Text below is from Half-Shot.


Today marks my last day of my 3 month internship at New Vector (the startup which hires many of the core Matrix team). For those of you who haven't been reading Ben's fabulous blog posts, I've been working exclusively on bridges; in particular the IRC bridge.

Tasked with the goal of making it crash less and run faster, I hope that the evidence is visible and people are generally having a better experience on it!

Some stats pulled from the matrix-appservice-irc repo:

  • 39 PRs closed (4 remain open)
  • 27 issues closed, 27 issues opened.
  • 334 commits, averaging 7.6 commits a PR.
Commits this year: Commits this year

But aside from showing off some stats, I wanted to mention all the new features:

  • Replies on Matrix translate well to IRC, or as well as IRC allows.
  • People mentioning your IRC nick now ping your matrix user, finally!
  • So. Many. Metrics. Everything you wanted to know about the internals of the bridge, but were too afraid to --inspect.
  • Not spamming homeservers with join requests on startup (it makes for a happy ops team).
  • No longer are IRC users shackled to a "(IRC)" extension on their displayname, you can be who you want with group flairs!
  • Support for node 4 has been dropped, and support for 6,8 and 10 has been assured.
On the matrix-appservice-bridge side, I optimised some calls to cache locally and avoid hitting the homeserver too often, and disabling presence for homeservers that don't support it.

There are future plans to make bridging more visible to Matrix Clients as a first class citizen. Ideas like speccing a state event (MSC1410) so that bridges can interact with each other properly and clients can create full bridge management views which are still decentralised from an integration manager.

I'd like to give a shoutout to Travis who has reviewed nearly all my changes that have made their way into the bridge, on top of all the other tasks he has on his plate. And of course a thank you to all of the Matrix team who have been very supportive during my time here.

This Week in Matrix 2018-08-24

24.08.2018 00:00 — This Week in Matrix Ben Parsons

Synapse 0.33.3

Big week for Synapse: v0.33.3 was released this week. You'll find preparation for support for Lazy Loading and Room Versioning, lots of bugfixes, and a great contribution from vojeroen: support for sending SNI over federation for vhosted servers. More complete change log here, features below:

  • Add lazy-loading support to /messages as per MSC1227 (#3589)
  • Add ability to limit number of monthly active users on the server (#3633)
  • Support more federation endpoints on workers (#3653)
  • Basic support for room versioning (#3654)
  • Ability to disable client/server Synapse via conf toggle (#3655)
  • Ability to whitelist specific threepids against monthly active user limiting (#3662)
  • Add some metrics for the appservice and federation event sending loops (#3664)
  • Where server is disabled, block ability for locked out users to read new messages (#3670)
  • set admin uri via config, to be used in error messages where the user should contact the administrator (#3687)
  • Synapse's presence functionality can now be disabled with the "use_presence" configuration option. (#3694)
  • For resource limit blocked users, prevent writing into rooms (#3708)
Ananace has upgraded his K8s-optimized Synapse image to 0.33.3

Spec

  • A large chunk of e2e has landed in the spec, largely thanks to Zil0's work. There are still some things left, but the main bits related to sending encrypted messages is in there. Attachments and key sharing are being reviewed today
  • TravisR progressed on Push, Application Services, and Client-Server APIs.
  • To follow along with progress, the best place to look is the August 2018 r0 tracker.

E2E

Key backups are being worked on, and we've had some new thoughts on key verification.

ru-matrix.org

Well are you?

Alexey and ma1uta have a new Russian-language community wiki available at https://ru-matrix.org. This:

accumulates Russian translates of Matrix FAQ and manuals, and other info about Matrix in Russian. Also we starts a public Matrix Synapse server for Russian users with free open registration

Russian Matrix users: feel free to add and complement articles in our wiki to make Matrix more friendly for Russian users.

Client News

Seaglass

neilalexander has been on a roll the last few weeks working on Seaglass, the macOS-native client:

Seaglass now has support for creating, joining and leaving rooms, and accepting/rejecting room invites, redacting messages, improvements to the room settings pages, timestamps, some visual tweaks, lots of bug fixes, early support for detecting failed message sends, scrolling improvements

Matrique

Black Hat continues work on Matrique, a glossy Qt client:

Typing notification and desktop notification of Matrique are working, plus other improvements

See the latest commits here.

Riot Web

Lazy Loading (LL) is available on develop behind the LABS flag, and is being polished. It will probably not make it to next release, but it's progressing!

Riot Mobile

New releases are imminent for both Android and iOS:

  • iOS: bug fixes and Lazy Loading in settings
  • Android: bug fixes, better management of permission requests at startup

Shared Secret Auth and Matrix Corporal

Slavi has been working on several operations tools for Synapse. Firstly Shared Secret Auth password provider module for Matrix Synapse.

It allows external systems (which know the shared secret) to easily obtain access tokens for any user hosted on the homeserver. This is incredibly useful for all sorts of automation (no more pre-generated access tokens or plain-text passwords).

With this tool, you can pass a mxid, and get back an access_token for that user. With this, you can do whatever actions would normally be done with a token. For example, you for a new starter at a company, you could join a set of rooms known to be needed by new starters.

Support room for Shared Secret Auth: #matrix-synapse-shared-secret-auth:devture.com

Next, he has released Matrix Corporal, reconciliator and gateway for a managed Matrix server:

It's a way to take control of Matrix (Synapse) in a corporate (or other such) environment.
Based on a configuration policy (generated by an external system, like your intranet), it can auto-create and auto-disable users, keep their profile and authentication details to date, auto-join/leave users to communities and rooms, etc.
It's also meant to sit in front of the Matrix Synapse Client API, inspecting and allowing/denying requests, in accordance with the configuration policy (preventing people from leaving certain rooms/communities, preventing them from messing around with their profile details, etc.)

Support room for Matrix Corporal: #matrix-corporal:devture.com

Note that Slavi also maintains matrix-docker-ansible-deploy, which can deploy these projects along with Synapse itself.

Bots

twimbot

I was extremely young when I first read and understood Larry Wall's explanation about the virtue of laziness, but I did not expect it to lead here. Cadair has created (I think inspired by an idea from TravisR), a "twimbot". This bot works in conjunction with opsdroid and the opsdroid connector-matrix - it works by storing selected messages from #twim:matrix.org in room state. In this way, it either assists the author by making it easier to produce the blog post you're reading, or it coldly replaces the author, leading to his sacking and penury. To view updates currently held by the bot, join #twim_updates:cadair.com.

Hashtag bot

When he's not working away on the Matrix Spec, TravisR continues to work on less [essential|sane] Matrix projects. This week we have @hashtag:t2bot.io, a bot that converts #hashtags to Matrix groups.

Why? Because why not. Source available on github: https://github.com/turt2live/matrix-hashtag-bot

Bridges

matrix-appservice-bridge and matrix-appservice-irc

Half-Shot will only be working full time with the Matrix Core team for another week (!!!), but until then he's going full-speed with bridge work. First matrix-appservice-irc:

Just pushed out matrix-appservice-irc 0.11.0-rc3 which contains a lot of nice things. The full changelog is there, hoping to get some of this tested and running on the matrix.org servers soon, but initial testing looks good :)

Having worked so much on IRC bridging the last few months, Half-Shot has this week managed to make improvements to matrix-appservice-bridge:

Released matrix-appservice-bridge 1.6.0 which contains mostly things I was writing for the irc bridge and factored out instead. There's a couple of goodies like automatic caching of profiles/events, and getEvent as a way to fetch events from the homeserver without fiddling with context.

Full changelog: https://github.com/matrix-org/matrix-appservice-bridge/blob/1.6.0/CHANGES.md

Some Intent operations now cache requests that would otherwise fall through to the homeserver which can be expensive. This is configurable for Intents via the opts.caching.ttl and size options. AgeCounters now allow you to set your own time period buckets. Added a new function Intent.getEvent which will fetch events from the homeserver without any context information, which should be quick. MembershipCache is now exposed to let folks read and write to the cache while also letting the bridge access it.

a release: Fix issue where roomState would fail. b release: Fix issue where we were calling this.intent inside intent like fools! c release: Fix issue where some stole js-sdk code was not checked thoroughly.

WhatsApp

tulir announces that mautrix-whatsapp "is now somewhat usable for basic chatting".

It uses the go-whatsapp library to talk with the WhatsApp Web API. Using the web API means that you'll still need WhatsApp on your phone connected to the internet, but it also means you won't get banned for using the bridge.
The bridge is still very alpha, but basic message bridging and some advanced features already work. There's a features & roadmap document about that.

To come chat about the WhatsApp bridge: #whatsapp:maunium.net.

mxtoot

mxtoot is a Matrix-Mastodon bot from ma1uta, creator of Jeon and the ecosystem around it.

There were two releases last week:

0.4.6 with additional commands (follow, unfollow, mute, unmute, block, unblock users, show followers and followings of the specified user) and a little bugfix.

0.4.7 is out now, which increases the length of messages to 4000 characters.

GSOC is finished!

GSOC 2018 has been valuable for everyone involved!

  • Thank you zil0 for all your work on the Matrix Python SDK, E2E and and spec work.
  • Thank you APWhiteHat: lots of work on dendrite, including a bunch of stuff on federation, as well as typing notifications!
  • and thank you to Cadair for helping to organising it!

The Construct using asynchronous disk IO

Jason writes:

the Construct has advanced to fully asynchronous disk IO in a single-threaded environment.
RocksDB is a highly configurable and customizable database with a very large callback surface to support many different environments, which is good to connect it with something like AIO.
Normally RocksDB gets its performance from concurrent standard POSIX system calls (blocking IO) with multiple threads. The callback surface and its internals are not specifically suited for deviating from the pthread model. However I hacked RocksDB and tricked it into believing that my userspace contexts, which mimic the std::thread/pthread interface, are threads.
This is an example of a RocksDB callback to read from a file, it expects this callback to return immediately (i.e as soon as the kernel returns from a blocking read(2).) Except, where I call fs::read() that is actually a stack-suspension which makes a request to linux AIO where the stack resumes after AIO has called back with the data (see: https://github.com/jevolk/charybdis/blob/master/ircd/aio.cc)
No modifications to the internals of RocksDB were necessary. The Construct is being developed here: https://github.com/jevolk/charybdis.

Community Guides Index

Some weeks ago I asked for suggestions for content to add to a "Community Guides Index". There was not a wave of feedback, but we have enough collected content to be able to share a first pass of this Index. Check out the content there, and please please contact me if you have articles, videos or anything else you'd like to see included. Of course, if you'd like to produce some content and have it included, that would be great too! Ideas for missing articles:

  • any content in a language other than English
  • DevOps, how to use k8s or ansible to install Synapse
  • how to use the Application Services API to make a bot

OggCamp 2018

OggCamp last weekend was great - massive thank you to Jon for organising and running the show - we love your work!

Presentations from Ben and Half-Shot seemed to go down well, we all chatted with Open Source fans and generally flew the flag for Matrix.

New Rooms

So long…

Hope you had a good week, hope you enjoyed reading this post! Amandine is back after some needed vacation time, and has this week's Matrix Live below.

This Week in Matrix 2018-08-17

17.08.2018 00:00 — This Week in Matrix Ben Parsons

This feels like a bumper (extra big) post, so let's get straight into it!

Spec

TravisR continues to plow through work in documenting, clarifying and confirming the spec. You can check out his project on Github: August 2018 r0, which should give an idea of both the scale of the project and the amount of work which has been done. Rather than list out individual items as I have been, please take a look at that project, and come chat in #matrix-spec:matrix.org if you'd like to contribute.

Clients

Riot web

Some exciting things on Riot Web this week!

Bruno has merged his work on lazy loading room members lists, which should mean we see some big performance improvements, especially in larger rooms. You can expect to see that released on /develop soon.

He has also just started to work on the riot redesign, and has begun on some of the more visible changes like resizeable panels:

More news on the redesign to come soon!

nheko 0.5.3 released

nheko 0.5.3 was released this week. From the changelog:

Features

  • Add option to disable desktop notifications
  • Allow user to configure join rules for a room
  • Add tab-completion for usernames
Improvements
  • Remove the space gap taken by the typing notifications
  • Remove hover event from emoji picker
  • Add tooltips for the message indicators
  • Fix compilation on FreeBSD
  • Update Polish translation
  • Small modal improvements

Seaglass builds being generated

Seaglass, the MacOS-native client, now has automatically generated builds available on bintray.

Seaglass is now a very usable and stable client on macOS. neilalexander has been very active this week:

Seaglass has had various updates, including the groundwork for joining and leaving channels, LOADS of crashes fixed, some more work done on avatars and E2E encryption has been fairly well road-tested now Still need to complete UI for device verification and setting E2E but it works fine in existing channels

Quaternion

kitsune has been working on Quaternion:

Quaternion has gained a new way to highlight mentions - with tinted background instead of colored text. Also, the majority of work on rooms grouping is done, and the current master branch features the roomlist grouped by tag (but rooms under each tag are pretty much out of order so it's not really ready for daily use yet).

Quaternion is looking for a macOS packager - if someone has the chance to help out in this area, speak to kitsune in #QMatrixClient.

Palaver

Arne came at us with the v0.2.1 release of Palaver:

A few days back Palaver has been moved to Gitlab. And I have since released v0.2.0 and v0.2.1. A runnable jar-file of the latest release can be downloaded at https://gitlab.com/MrCustomizer/palaver/tags/v0.2.1. The biggest changes in v0.2.x are the replacement of all the web views with native JavaFX components (as I don't feel comfortable embedding a whole browser stack in a desktop application) and support for read markers. There is a short YouTube video demonstrating the read marker implementation:

Riot mobile

This week, work continued on Lazy Loading room members for Riot Android, and progress toward a release for 0.7.0 on iOS.

neo client

f0x has begun rewriting Neo using matrix-js-sdk.

Matrique

Black Hat has been working on Matrique:

Matrique now has a (basic) room management panel, a working emoji picker, an unread marker and supports playing "m.audio". It should be available at Flathub any time.

SDKs and such

Jeon, Jmsdk, Gene, Matrix-Jabber-Bridge: ma1uta-world

ma1uta is continuing to make progress on his Java-focused collection of APIs and SDKs, he's eagerly awaiting the r0 release of the spec (aren't we all!)

Jeon (https://github.com/ma1uta/jeon) (client2server and application api) has released on the Maven Central Repository with version 0.4.1. The next goal: the stable release of all apis 1.0.0 after the Matrix spec will be released (I hope it will be soon :)) Jmsdk (https://github.com/ma1uta/jmsdk) the client and bot SDK have released on the Maven Central Repository. Gene (https://github.com/ma1uta/gene) the lightweight api for android has released on Maven Central Repository with 0.2.1 version. So, everyone can use this libraries without additional settings and additional repositories. Matrix-Jabber-Bridge (https://github.com/ma1uta/matrix-jabber-java-bridge) the double-pupped bridge between the Matrix and Jabber. I am still working on it and I think it will be released in a few weeks.

Ruby SDK v0.0.3

Ananace has tagged and released the next development version of the Ruby Matrix SDK - 0.0.3. He has plans to "finish up documentation and unit testing", with the aim of making a v1.0.0 release.

mautrix-appservice-go

tulir has a new, yet-to-be-revealed project, and in support of this he's been working again on mautrix-appservice-go:

mautrix-appservice-go is a bit more active again: it now has an initial intent API similar to the one in mautrix-appservice-python (which in turn is based on the intent API from matrix-appservice-bridge).

Synapse

No release this week, but Synapse has been progressing:

  • Python 3 port continues at pace, we expect to have a beta to test in monolith mode rsn (Hawkowl leads this)
  • Erik has been working on some federation API refactoring to make matrix.org snappier and hopes to have the new state resolution algo ready to go if not deployed late next week
  • Richvdh has been looking at performance, as well as spec PRs/ Next week will be r0 work
Many Synapse maintainers are also doing huge lifts on development of the spec.

Matrix support now in ntfy

Half-Shot took a rare 30-minute window away from bridge maintenance to add Matrix support to ntfy. ntfy describes itself as

A utility for sending notifications, on demand and when commands finish

but in fact, you also send notifications whenever you like by calling ntfy send from anywhere you'd normally execute shell commands. This will make it really easy to integrate Matrix notifications into any other application!

matrix-docker-ansible-deploy

Slavi brought updates to matrix-docker-ansible-deploy:

matrix-docker-ansible-deploy got a lot of improvements lately:

  • email-sending support, so that Matrix Synapse can send email notifications (enabled by default)
  • mxisd Identity Server support (enabled by default)
  • more detailed docs split into various sections (used to be a single README, but with more and more features it was turning into a wall of text)
  • started keeping a changelog, especially for backward-incompatible things
the playbook can now also set up and configure Maximus's matrix-synapse-rest-auth

Riot Translations

@csybr:dodsorf.as and @dandellion:dodsorf.as appeared and announced that there is now a Norwegian Nynorsk translation available for Riot Web, matrix-react-sdk and riot-android. Non-Matrix-related aside: as a lazy Brit, I was vaguely aware of the cultural weight language carries in the history of Scandinavia, but didn't realise that Norway still has some fundamental differences ongoing.

Giveth

The Giveth project have produced a bot built on matrix: giveth-bot

For some more context:

Giveth is re-engineering charitable giving, by creating an entirely free, open-source platform, built on the Ethereum Blockchain.

The current giveth-bot:

handles welcoming people, can answer questions and handle our crazy points dishing system to reward contributors!

mautrix-telegram

mautrix-telegram now has an official 0.3.0 release. Says tulir:

No major changes since the release candidates last week, except a Telethon update that might have fixed history backfill.

"The End of GSOC"

Well, it may well be the end of the Julian's GSOC 2018 experience with the Fractal project, but I think Google will continue to run the programme. Check out Julian's experience (and the large number of issues resolved!) in this blog post.

OggCamp

This weekend Neil and I will be representing Matrix at OggCamp, "an unconference celebrating Free Culture, Free and Open Source Software, hardware hacking, digital rights, and all manner of collaborative cultural activities", if you will be there, come find and chat to us. We'll be the two nerdy-looking guys, so we should be easy to spot.

We'll meet again…

But for now, you can watch Neil host Matrix Live below (using the fan-favourite format of walking around the office), and come chat to us in #twim:matrix.org

This Week in Matrix 2018-08-10

10.08.2018 00:00 — This Week in Matrix Ben Parsons

Community Guides Index

As part of an overhaul of the documentation surrounding Matrix, I'm planning to launch a "Community Guides Index". This will be a page or section on Matrix.org with links to useful and informative documentation hosted elsewhere. If you have or know of informative articles, please let me know, or share them in #TWIM:matrix.org.

Clients

Seaglass

Seaglass now supports E2E rooms, leveraging matrix-ios-sdk! Additionally, maintainer neilalexander has had a productive week:

Seaglass has had many updates, including:

  • message coalescing
  • room settings (history/join rules and changing aliases/addresses)
  • loading member list in rooms
  • some starting work on loading avatars
  • various UI and stability tweaks!

Quaternion: new redacted message handling options

Many of you will have seen the incredible volumes of spam plaguing Freenode over the last few weeks. Kitsune has added new features to Quaternion to help:

In response to the recent spam deluge from Freenode Quaternion has got an option to tidy up your timeline after all the spam-cleaning: you can hide all redacted messages or just those that came from recently joined users (along with the join message). So as long as the spammer gets moderated, it can become inexistent for you. The experimental code doing that will eventually be moved to libQMatrixClient for the benefit of Matrique, uMatriks and other clients based on the library.

This is especially cool: moving functionality to the lib for the benefit of other projects makes me very happy. :D

Fractal GSOC write-ups

Eisha and Julian finished their GSOC 2018 Fractal involvements this week, and Eisha has a blog post recounting her experience: My Final Report for GSOC 2018. Julian will have his ready too.

Riot

Big updates are on the horizon for both iOS and Android, with 0.7.0 of iOS headed to TestFlight today with a release due once it's through beta & AppStore review.  More details once the releases are out!

Meanwhile on Riot/Web, Lazy Loading members is pretty much complete - just writing end-to-end tests to ensure that encryption still works well when lazy loading is enabled.  Next up is actually progressing the redesign at last!

Spec status

  • MSC1425/MSC1501 richvdh has been thinking about Room Versioning
    • A summary in his words: "room upgrades are implemented by creating a new room, shutting down the old one, and linking between the two"
  • MSC1497 thorough discussion happening against Matthew's proposal for Capabilities support in the CS API
  • MSC1442 though you may have seen it previously, I recommend anyone who is able to take a look at Erik's "State Resolution: Reloaded" proposal. This documents his "thoughts on the next iteration of the state resolution algorithm that aims to mitigate currently known attacks". It very clearly explains the current problem, and the proposed solution. While heavy, I found it really useful for helping to understand State Res and everything it affects.
  • MSC1485 tulir proposes "Hint buttons in messages", which effectively provide pre-defined responses for users. This is especially valuable for Bots which can only accept a certain range of replies. I'd love to see this implemented, having long ago built a "choose your own adventure" engine using similar features from another messaging platform.

APIs and SDKs

Gene, minimalistic client-server api for Matrix

Not strictly this week, but we missed it before. ma1uta has been working away on his Java-based Matrix suite. Gene is a more lightweight API implementation than Jeon, covering all of the current C2S spec. A big motivation is to be able to use Gene on Android, which is not possible for Jeon due to it having more dependencies.

Ruby Matrix SDK

The Ruby Matrix SDK now has auto-generated, proper documentation, thanks to Ananace. v0.0.2 is the current release, but it's under active development and v0.0.3 is expected presently.

Telegram Puppeting on t2bot.io with mautrix-telegram

TravisR has rolled out tulir's mautrix-telegram bridge for everyone on t2bot.io's bridge.

This is a public trial to see how the bridge copes with multiple people puppeting their accounts. Of course, you don't need to puppet your account unless you want to. For more information on how to set this up, please visit https://t2bot.io/telegram

As part of this project, mautrix-telegram 0.3.0 release candidate was released.

Informo project releases SaltStack states

vabd, from the Informo project, arrived to say they have produced "a set of SaltStack states that includes deploying fully working Synapse homeservers: https://github.com/Informo/salt-states"

They introduce the Informo project:

Informo's a project (still a work in progress, currently) that aims at bypassing censorship of information on the Internet, by basically having news items go through a decentralised and federated network made of Matrix homeservers. Since we need to host nodes to this network (at least for testing purposes), we've worked on a working and automated infrastructure using SaltStack, which involved hand-writing a few SaltStack states, including states handling the installation and configuration of working Synapse homeservers. In the spirit of giving back to the community, we're publishing all of those hand-written states (available at the GH link above) under the GPLv3 license. If you want to discuss with us about what we're doing, or this topic specifically, please join us in #discuss:weu.informo.network ? The project is still pretty much a WIP and the technical specifics (even the ones we already implemented in our projects) are still under discussion and subject to changes (as mentioned in the GH repo's readme). All I can add for sure to what we already say is that we'll be working in partnership with NGOs to promote the project in countries where the press is heavily censored, and we're planning on implementing a cryptographic verification chain of some sort to reduce the risk of intentional disinformation.

Synapse 0.33.2

Synapse 0.33.2 is out now:

The release focuses on performance, notable highlights include reducing CPU consumption through speeding up state delta calculations and reducing I/O through lazily loading state on the master process Separately work continues on our python 3 port and we hope to have something concrete to trial very soon – we're really excited about this and expect step change improvements in CPU and memory use.

Latest synapse is now available on Debian thanks to andrewsh.

Room Tagging

This is not from this week at all, other than that it was new information to me. Actually it's ancient, matrix-wise, but I think it's interesting for those who don't know! Although Riot doesn't have an interface for adding custom room tags ("Favourites" and "Low Priority" come by default), Matrix supports arbitrary strings as room tags, and will display them if you add them via another CS API call. To facilitate this TravisR created a small script, tag_room.sh, which makes it very simple to set your own room tags.

FIN

That's all folks! Remember, lots of progress is happening with the Spec, if you want to be involved or follow along the best place to start is by joining #matrix-spec:matrix.org.

No Matrix Live this week due to vacation and general scheduling fun; sorry!

If you have documentation or articles related to matrix, let me know!

We'll meet again!

Synapse 0.33.2 is here!

09.08.2018 00:00 — Releases Neil Johnson

Folks, it's release time, Synapse 0.33.2 has landed.

The release focuses on performance, notable highlights include reducing CPU consumption through speeding up state delta calculations (#3592) and reducing I/O through lazily loading state on the master process (#3579#3581#3582#3584)
