### Dendrite / gomatrixserverlib
|
||
|
||
Dendrite is a next-generation homeserver written in Go
|
||
|
||
[Neil Alexander](https://matrix.to/#/@neilalexander:matrix.org) told us:
|
||
|
||
> This week we have largely been working on bug fixes and performance issues.
|
||
>
|
||
> Changes this week include:
|
||
>
|
||
> * The room server now handles input events for multiple rooms in parallel when running with PostgreSQL, which helps a lot with perceived latency
|
||
>
|
||
> * Device key queries now obey federation backoffs, so that we don't spend a lot of time making unnecessary requests
|
||
> * The key server now only emits changes for `/users/devices` which reduces database hits significantly
|
||
>
|
||
> * The client API now tries to guarantee message ordering on a per-user basis (thanks Anand!)
|
||
> * Federated invites are now more reliable and are performed synchronously
|
||
>
|
||
> * Invite room metadata is now sent correctly in all cases
|
||
> * Accepting and rejecting invites is also now much more reliable
|
||
>
|
||
> * A bug has been fixed that caused excessive memory usage in the sync API (bringing the memory usage of my own instance down to less than 100mb)
|
||
> * A massive amount of work has been done to reduce database locks in SQLite mode across the entire codebase
|
||
>
|
||
> * Some unnecessary code has been removed from the roomserver updaters
|
||
>
|
||
> Spec compliance has improved slightly:
|
||
>
|
||
> * Client-Server APIs: 54%, same as last week
|
||
>
|
||
> * Server-Server APIs: 71%, up from 70% last week
|
||
>
|
||
> As always, feel free to join us in [#dendrite:matrix.org](https://matrix.to/#/#dendrite:matrix.org) for the latest!

|
||
|
||
> While work on federation is going on in the background, here are some other things we worked on this week
|
||
>
|
||
> * Arch AUR support (thanks to @s7evink)
|
||
>
|
||
> * Very efficient searching through rooms (custom implementation based on <https://artem.krylysov.com/blog/2020/07/28/lets-build-a-full-text-search-engine/>)

### Synapse
|
||
|
||
[Neil](https://matrix.to/#/@neilj:matrix.org) said:
|
||
|
||
> This week we added some more federation readers to matrix.org which should noticeably improve federation lag.
|
||
|
||
|
||
|
||
> Patrick has continued on with the async/await-a-thon and we are starting to enter the home stretch. Of the things we care about only ```runInteraction``` remains. Once done we can get on with profiling the main process.
|
||
|
||
|
||
|
||
> On the sharding side the last big milestone is to get the event persister to shard. I know this comes up every week, but we now have a rough working implementation for non-backfilled events. Next steps are to get backfill working, get the tests passing, go through review and then ship. I asked Erik if it would be live on matrix.org within 2 weeks. He didn’t say, at least I didn’t hear him say no…>
|
||
> Aside from that Rich is working on the push rules redesign, the next steps are to design the APIs in more detail and then make a formal spec proposal. Brendan is also in notifications land and his work on room unread counts is going through final review.
|
||
>
|
||
> Finally, Andrew has been working with Sorunome to dust off the knock feature, both on the spec and [the Synapse side](https://github.com/matrix-org/synapse/pull/6739).

### Romeo and Juliet benchmark to compare Matrix server implementations
|
||
|
||
[timo](https://matrix.to/#/@timo:koesters.xyz) offered:
|
||
|
||
> This week I created the first(?) Matrix server benchmark and ran it on Synapse, Dendrite and Conduit. The test will go through the entire Romeo and Juliet play and create users for each character and sends messages for each line they say.

There is some question here about how federation and state resolution will affect performance on these tests.

|
||
## Synapse Deployment 📥️
|
||
|
||
There is rather a lot in this section this week (see also Ops 🛠 section below.) I'll consider making this a more structured (table?) feature in future.
|
||
|
||
### SELinux policy module
|
||
|
||
[0xC0ncord](https://matrix.to/#/@concord:fuwafuwatime.moe) reported:
|
||
|
||
> Hello! Just recently I made public an SELinux policy module I developed for Synapse. This policy is one I developed early on during my trip down the SELinux rabbit hole, and I have been using it in production for some time. At the moment, this policy module is built for the Gentoo SELinux policy (not RHEL/CentOS/Fedora) and does not currently have systemd support, nor has it been tested in all environments, i.e. with workers. I am publishing this policy in the hopes that it will be useful and I am open to any contributions, even those to help tighten the policy if possible. Finally, I have also made public a policy module for coturn, which I am also using in my own personal environment under the same conditions. Both the [Synapse](https://github.com/0xC0ncord/synapse-selinux) policy and the [coturn](https://github.com/0xC0ncord/turnserver-selinux) policy can be found on Github. Thank you!

### Telegram public channel mirror
|
||
|
||
[bo41](https://matrix.to/#/@bo41:matrix.org) reported:
|
||
|
||
> As channels are really popular in Telegram, I wrote a quick and dirty program/bot which can mirror (text and image) public Telegram channels to Matrix rooms. This should make it easier for Telegram users to consider a switch.
|
||
>
|
||
> Making the rooms read-only via permissions prevents messages from users.
|
||
> It provides a good basis for someone trying to make a real 1to1 mirror. Please fork this project and host some channels publicly ;)
|
||
>
|
||
> <https://git.sr.ht/~bo41/matrix-channel-mirror>
|
||
|
||
This project is functionally quite different from the more established mautrix-telegram: it is purely designed to mirror content from Telegram public rooms.

[Nico (@deepbluev7:neko.dev)](https://matrix.to/#/@deepbluev7:neko.dev) reported:
|
||
|
||
> I've been working on trying to finish the event store (when I wasn't distracted by video calls with some people). This should allow limited offline use and reduce memory use as well as allow some other features in the future. If you want to try it out, you can build [this PR](https://github.com/Nheko-Reborn/nheko/pull/251) or try out the nightlies with `new-event-store` in their name.
|
||
>
|
||
> If you decide to try it out, backup your cache or at least BACKUP YOUR ENCRYPTION KEYS! I won't be responding to feedback immediately, since I am currently hiking, but I should get to it this weekend or next week. Come discuss it in [#nheko:ocean.joedonofry.com](https://matrix.to/#/#nheko:ocean.joedonofry.com), if you have some feedback or issues.

### Hydrogen
|
||
|
||
Hydrogen is a web-based client designed to be very lightweight, and with few dependencies.
|
||
Anyone who wants to discuss Hydrogen can join [#hydrogen:matrix.org](https://matrix.to/#/#hydrogen:matrix.org).
|
||
|
||
[Bruno](https://matrix.to/#/@bwindels:matrix.org) told us:
|
||
|
||
> Added several features this week:
|
||
>
|
||
> * avatars and display names in the timeline and for rooms
|
||
> * implemented the logic for the member list, but no UI for this yet
|
||
>
|
||
> * room list sorting by last message timestamp, unread state and badge count
|
||
> * clear unread state when reading a room
|
||
>
|
||
> * some visual tweaks in the timeline and room list
|
||
> * bug fixes
|
||
>
|
||
> If you have checked out hydrogen before, **you'll need to clear your session** (the little clear button in the session picker) to get correct avatars and display names everywhere.
|
||
>
|
||
> Next week I'll get started on E2EE, which should make the project a lot more useful. I'll look into leveraging the nice rust matrix-crypto-sdk for this.

### Mirage 0.6.1
|
||
|
||
[miruka](https://matrix.to/#/@miruka:privacytools.io) hit us with a late breaking update about Mirage!
|
||
|
||
> Mirage 0.6.1 was released today:
|
||
>
|
||
> #### Added
|
||
>
|
||
> - **SSO authentication** support
|
||
>
|
||
> - **Homeserver browser**:
|
||
> - To add a new account, you will be asked first to pick one of the
|
||
> listed public server (list data from [anchel.nl](https://publiclist.anchel.nl/)) or to manually enter a server address
|
||
|
||
> - Typing in the server address field will also filter the public server list,
|
||
> Up/Down or (Shift+)Tab and Enter can be used to navigate it by keyboard
|
||
>
|
||
> - If the address doesn't have a `scheme://`, auto-detect whether the server
|
||
> supports HTTPS or only HTTP
|
||
>
|
||
> - Use the .well-known API if possible to resolve domains to the actual
|
||
> homeserver's URL, e.g. `matrix.org` resolves to
|
||
> `https://matrix-client.matrix.org`
|
||
>
|
||
> - The server address field will remember the last homeserver that was
|
||
> connected to
|
||
>
|
||
> - **Room members autocompletion**:
|
||
> - Type `@` followed by one or more characters in the composer,
|
||
> or one or more characters and hit (Shift+)Tab to trigger username/user ID
|
||
> autocompletion
|
||
>
|
||
> - Only autocompleted names will be turned into mentions, unlike before
|
||
> where any word in a sent message that happened to be someone's name would
|
||
> mention them
|
||
>
|
||
> - **Full image viewer** for matrix image messages and URL previews:
|
||
> - Click on a thumbnail in the timeline to open the image viewer
|
||
>
|
||
> - Middle click on a thumbnail (or use the option in the context menu)
|
||
> to open the image externally
|
||
>
|
||
> - Left click on the image (mouse only): expand to window size if the
|
||
> image's origin size is smaller than the window,
|
||
> else expand to original size
|
||
>
|
||
> - Tap on the image (touch screen/pen only): reveal the info and button bars
|
||
> when auto-hidden (bars will auto-hide only when they overlap with a big
|
||
> enough displayed image)
|
||
>
|
||
> - Any mouse movement: reveal auto-hidden bars
|
||
> - Double click on the image: toggle full screen
|
||
> - Middle click anywhere: open externally
|
||
> - Right click anywhere: close the viewer, back to chat
|
||
> - Drag when displayed image is bigger than window to pan
|
||
> - Wheel to pan up/down, hold shift or alt to pan left/right
|
||
> - Ctrl+wheel to control zoom
|
||
> - Buttons to control rotation, scale mode, full screen, GIF play/pause
|
||
> and GIF speed
|
||
>
|
||
> - New keyboard shortcuts are available for all these actions,
|
||
> see `keys.imageViewer` in the config file (will be automatically updated
|
||
> when you start Mirage 0.6.1)
|
||
>
|
||
> - Add `media.openExternallyOnClick` setting to swap the new
|
||
> click and middle click on thumbnails behavior
|
||
>
|
||
> - Room and member filter fields now support (Shift+)Tab navigation, in addition
|
||
> to Up/Down
|
||
>
|
||
> - Add a colored left border to the currently highlighted item in list views
|
||
> (e.g. room list, members list, etc) to improve visibility
|
||
>
|
||
> - Themes:
|
||
> - Add `controls.listView.highlightBorder` and
|
||
> `controls.listView.highlightBorderThickness` properties (can be set to `0`)
|
||
> - Add the `chat.userAutoCompletion` section
|
||
>
|
||
> #### Changed
|
||
>
|
||
> - Messages context menu:
|
||
> - Use a cleaner icon for the "Copy text" entry
|
||
>
|
||
> - Replace the confusing broken "Copy media address" entry with:
|
||
> - Copy media address: visible for non-encrypted media, always
|
||
> copies the HTTP URL
|
||
>
|
||
> - Copy local path: always visible for already downloaded media, even if
|
||
> they were downloaded before mirage was started
|
||
>
|
||
> - The `openMessagesLinks` keybind (default Ctrl+O) is renamed to
|
||
> `openMessagesLinksOrFiles` and can now also open media message files
|
||
>
|
||
> - Using the `openMessagesLinksOrFiles` keybind on a reply will now ignore the
|
||
> matrix.to links contained in the "In reply to XYZ" header
|
||
>
|
||
> - Pressing Ctrl+C to copy selected/highlighted non-encrypted media messages
|
||
> will copy their HTTP URL instead of the filename
|
||
>
|
||
> - Retry downloading image thumbnails if they fail with a 404 or 500+ server
|
||
> error (uploads sometimes take a few seconds to become available on the
|
||
> server)
|
||
>
|
||
> - Non-encrypted media messages are now always downloaded on click and opened
|
||
> with a desktop application (or the image viewer), instead of
|
||
> being opened in a browser
|
||
>
|
||
> - Compress thumbnails and clipboard images in a separate process, to avoid

### Ruma
|
||
|
||
[iinuwa](https://matrix.to/#/@iinuwa:matrix.org) offered:
|
||
|
||
> We wanted to take a little bit of time to show off a state resolution library for Ruma, courtesy of @DevinR528 and @Timo. Ruma has a new crate to make resolving state easier, [state-res](https://github.com/ruma/state-res)! The goal of this crate is to be the base for federation, it provides the necessary utilities to resolve state, sort power events (reverse topological ordering), sort events (based on mainline depth), and a lot of event authentication functions. It is still in the early stages of development, but will be hopefully proved out in [Conduit](https://git.koesters.xyz/timo/conduit).
|
||
>
|
||
> Other things that happened this week:
|
||
>
|
||
> * Added the invite endpoints from the Federation API
|
||
>
|
||
> * Started requiring strong types for event-sending endpoints
|
||
> * Augmented error types with error-specific fields (see the [livestream here](https://www.twitch.tv/videos/713341462?t=00h35m42s))
|
||
>
|
||
> Speaking of livestreams, @jplatte streams coding sessions from time to time on [Twitch](https://twitch.tv/jplatte). If you're interested in watching some coding streams to get more familiar with the Ruma codebase or learn Rust in general, follow us at [[#ruma-livestreams:matrix.org](https://matrix.to/#/#ruma-livestreams:matrix.org)](https://matrix.to/#/[#ruma-livestreams:matrix.org](https://matrix.to/#/#ruma-livestreams:matrix.org))!
|
||
|
||
Very impressed that these features are landing in Ruma first, with the intention of getting them into Conduit.

### mautrix-go
|
||
|
||
[nikofil](https://matrix.to/#/@nikofil:matrix.org) reported:
|
||
|
||
> * SSSS and cross-signing are slowly making their way to mautrix-go! A [WIP PR](https://github.com/tulir/mautrix-go/pull/18) exists for both features and is being developed upon. This will allow any clients that use the library to eventually be able to use SSSS and verify the trustworthiness of other devices based on cross-signing.
|
||
|
||
### Ruby
|
||
|
||
[Ananace](https://matrix.to/#/@ace:kittenface.studio) announced:
|
||
|
||
> Just pushed version 2.1.1 of the [Ruby Matrix SDK](https://github.com/ananace/ruby-matrix-sdk), mainly including a couple of fixes for various minor issues.

|
||
### matrix-docker-ansible-deploy
|
||
|
||
This [Ansible playbook](https://github.com/spantaleev/matrix-docker-ansible-deploy) is meant to easily let you run your own Matrix homeserver.

|
||
|
||
> [matrix-docker-ansible-deploy](https://github.com/spantaleev/matrix-docker-ansible-deploy) now makes it incredibly easy to use [rust-synapse-compress-state](https://github.com/matrix-org/rust-synapse-compress-state) to compress the state groups in your Synapse database.
|
||
>
|
||
> See our [Compressing state with rust-synapse-compress-state](https://github.com/spantaleev/matrix-docker-ansible-deploy/blob/master/docs/maintenance-synapse.md#compressing-state-with-rust-synapse-compress-state) documentation page to get started.

### go-neb
|
||
|
||
[nikofil](https://matrix.to/#/@nikofil:matrix.org) said:
|
||
|
||
> * Device verification was merged to neb! It needs human intervention to approve that the SAS match, of course.
|
||
>
|
||
> * A new service called "cryptotest" was added that allows other clients to exchange e2e-related events with neb to test their capabilities (such as encryption, room key forwarding, SAS verification)

## Final Thoughts 💭
|
||
|
||
[Christian](https://matrix.to/#/@christianp:vector.modular.im) told us:
|
||
|
||
> Residents of Germany can apply for the [Prototype Fund](https://prototypefund.de/) until the end of September. They are looking for new open source ideas or features and fund about 20 projects twice a year with 47,500 EUR for six months (starting in April for this round).
|
||
>
|
||
> Previously funded chat-related projects include Briar and OpenPush.
|
||
> It would be great to see a project building on Matrix.
