Articles

Congrats to the Monal developers for the new NLnet Funding that will cover privacy enhancements for the push servers, an explorative audio and video calls implementation, UI updates for MUC and Contact views, and SASL updates.

Paul Schaub wrote a blog post focused on the technical details of how to check the validity of nested packet sequences using pushdown automata. This technique will be used in a partial rework of PGPainless to validate OpenPGP messages. Earlier this month another post on “Creating a Web-of-Trust Implementation: Accessing Certificate Stores” has been published, too.

jmp.chat brought voicemail changes and opt-in Jabber ID discoverability to their service, along with an updated Android app and new custom F-Droid repos for both stable and pre-release versions. Furthermore, they wrote about “Privacy and Threat Modelling” in general.

Arnaud wrote about updates on the chatty server and HTTPAuthentificationOverXMPP .

Anoxinon.media published their blogpost XMPP - Teil 1 - Messaging mal anders [DE].

Software news

Clients and applications

Maintenance release of Beagle IM 5.3.1 that fixes sending OMEMO encrypted files and entering password-protected MUC. Besides, Tigase launched a new, simpler website tigase.org that makes it easier to access open-source projects created by Tigase.

Gajim 1.5.0 and 1.5.1 have been released . These releases come with a significant performance boost. Pinned chats can be ordered via drag and drop, message corrections have been improved, and many bugs have been fixed.

An OMEMO 2 implementation has just been merged to Libervia , coming with Stanza Content Encryption ( XEP-0420 ) support, thanks to the great work of Syndace, author or python-omemo (which has been updated in the process). One of the major benefits is that other Stanza elements can now be encrypted too, not only the body. OX ( XEP-0373 / XEP-0374 ) should follow soon, exciting times!

While Monal development is going forward, see the funding news above, and they deployed new Push servers as announced in the July 2022 XMPP Newsletter, users of old Monal versions would need to update, so if you or your contacts didn’t already the developers urge you to do it now .

Missed in the August 2022 XMPP Newsletter was a release of UWPX, the XMPP client for UWP (Windows 10) devices. While version v.0.43.0.0 has only a fixup it’s unfortunately also the Final Update as the developer is stepping away from the project. Maintainers to follow-up are welcome to reach out!

Kaidan, a user-friendly and modern chat app for every device, will receive a grant by NLnet for adding encrypted audio and video calls . Congratulations!

Servers

Jackal v0.62.0 is out bringing XEP-0313 Message Archive Management support and several enhancements.

Metronome IM 4.0 has been released . This version introduces Lua 5.3 support, a revamped shared API for group chats stanza archiving, MIX Core/PAM experimental support, Message Moderation support and support for containerization.

Profanity 0.13.0 has been released.

Libraries & Tools

python-nbxmpp 3.2.2 and 3.2.3 have been released , adding a stringprep implementation and improvements for detecting broken TCP connections.

The first beta of Slidge (XMPP bridges) is out!: Slidge, supporting Signal, Telegram, Discord, Steam, Mattermost, Facebook and Skype. Currently only direct messages are supported, but development is going further. Find the article in English and French .

Work on XMPP ⇔ ActivityPub gateway (supported by a NLnel funding) has been achieved. The gateway supports features such as following/followers, favourite/like (or “noticed” in XMPP terms , reactions (compatible with Pleroma ), mentions, sharing/reboost and lastly events (compatible with Mobilizon ). It has been tested with Mastodon , Pleroma and Mobilizon. It’s still considered alpha quality, a blog post should follow soon to explain in more details .

Ignite Realtime Community:

• REST API Openfire plugin 1.10.0 has been released
• New Openfire plugin: Push Server

Extensions and specifications

Developers and other standards experts from around the world collaborate on these extensions, developing new specifications for emerging practices, and refining existing ways of doing things. Proposed by anybody, the particularly successful ones end up as Final or Active - depending on their type - while others are carefully archived as Deferred. This life cycle is described in XEP-0001 , which contains the formal and canonical definitions for the types, states, and processes. Read more about the standards process . Communication around Standards and Extensions happens in the Standards Mailing List ( online archive ).

xmpp.org features a page about XMPP RFCs as well.

Proposed

The XEP development process starts by writing up an idea and submitting it to the XMPP Editor. Within two weeks, the Council decides whether to accept this proposal as an Experimental XEP.

• Events
  • This specification describes how to handle calendar events with XMPP

New

• No new XEP this month.

Deferred

If an experimental XEP is not updated for more than twelve months, it will be moved off Experimental to Deferred. If there is another update, it will put the XEP back onto Experimental.

• No XEPs deferred this month.

Updated

• Version 0.4.0 of XEP-0440 (SASL Channel-Binding Type Capability)
  • Make sasl-channel-binding element a top level stream feature (dg)

Last Call

Last calls are issued once everyone seems satisfied with the current XEP status. After the Council decides whether the XEP seems ready, the XMPP Editor issues a Last Call for comments. The feedback gathered during the Last Call can help improve the XEP before returning it to the Council for advancement to Stable.

• No Last Call this month.

Stable

• No XEP moved to stable this month.

Deprecated

• No XEP deprecated this month.

Call for Experience

A Call For Experience - like a Last Call, is an explicit call for comments, but in this case it’s mostly directed at people who’ve implemented, and ideally deployed, the specification. The Council then votes to move it to Final.

• No Call for Experience this month.

Software news

Clients and applications

Conversations 2.10.9 and 2.10.10 have finally been released for both Google Play Store and F-Droid. Many people were eagerly waiting for a new Conversations build on F-Droid as there were some issues regarding the usage of WebRTC libraries, for Audio/Video calls. F-Droid users were still on the 2.10.2.1+fcr build but now, after 5 months of waiting, they are using the latest version. These releases improve interactions with Bluetooth output devices so be sure to grant the permission as needed. A note for jmp.chat users, the F-Droid version uses an incompatible WebRTC library, so it’s better to switch to the Cheogram app (a fork from the jmp.chat developers) at the moment. The Play Store version does not have this issue.

Moxxyv2 0.2.0, 0.2.1, 0.2.2, 0.2.3 have been released. A new XMPP client for the Android community is featured in this month’s newsletter; it is currently only in the alpha stage. However, the future of the project appears to be pretty promising, and we are pleased to have another XMPP project join the community! The initial version (0.2.0) was made available on July 29th, and the second version (0.2.1) was made available on August 14th. This project is the successor of moxxyv1, which was written in React Native and abandoned due to various technical issues.

Psi+ 1.5.1639 (2022-08-17) has been released.

Tigase released BeagleIM 5.3 (macOS) and SiskimIM7.3 (iOS) which contain changes and stability improvements. Note that SiskinIM will need at least iOS 13 from now on.

Servers

Openfire 4.7.3 has been released, which brings many bug fixes, especially for BOSH.

Libraries

libstrophe 0.12.2 has been released.

Mellium XMPP 0.21.3 has been released.

Tigase Martin 3.2.1 has been released.

From the ignite realtime community:

• REST API Openfire plugin 1.9.0 and 1.9.1 has been released to fix several bugs.
• Openfire ThreadDump plugin 1.1.0 has been released and add two new evaluators for the TaskEngine and statistics from the database connection pool.

It’s been a month since I wrote my last blog . For those of you who have been following my blogs, thanks a lot for taking the time to read them. In this blog, I will give the updates post mid-term evaluation and the challenges that I have been facing and how I overcame some of them.

The Mid-Term Evaluation

For those of you who don’t know much about GSoC, a mid-term evaluation was scheduled, where as a contributor you have to fill out a form which had some questions related to your experience with your mentor and the organization administrator so far and the project itself. It barely took me 5-10 minutes to complete the form so there’s that.

Project Updates & Challenges Faced

I have been working on the jingle message retraction feature and the jingle chat history feature. Let me explain:

If you have gone through XEP-0353 , you might be knowing about the retraction feature . If not, then the below two diagrams are my best attempts to explain it, and to be honest it is pretty simple.

Ok, now, let me show you another diagram which took me around 2 weeks to visualize:

This is what confused me the most and took a lot of my time. If you look at the way I have written my code (and I won’t link it, since I believe that the link might break in the future due to the constant changes in the codebase that are yet to come):

    // Responder's Side Parser
    function parseJingleMessage(stanza, attrs) {
    const jingle_propose_type = getJingleProposeType(stanza);
    return { ...attrs, ...{ 'jingle_propose': jingle_propose_type, 'jingle_retraction_id': getJingleRetractionID(stanza), 'template_hook': (attrs['template_hook']) ? 'getJingleTemplate' : undefined, 'jingle_status': attrs['jingle_status'] }
    }
    }

    // Initiator's Side
    function retractCall(context) {
    const initiator_message = context.model.messages.findWhere({ 'media': 'audio' });
    const propose_id = initiator_message.attributes.propose_id;
    const message_id = u.getUniqueId();
        api.send(
            $msg({
            'from': _converse.bare_jid,
            'to': context.jid,
            'type': 'chat',
            id: message_id
            }).c('retract', { 'xmlns': Strophe.NS.JINGLEMESSAGE, 'id': propose_id })
            .c('reason', { 'xmlns': Strophe.NS.JINGLE })
            .c('cancel', {}).up()
            .t('Retracted').up().up()
            .c('store', { 'xmlns': Strophe.NS.HINTS })
        });
        const attrs = {
            'from': _converse.bare_jid,
            'to': context.jid,
            'type': 'chat',
            'jingle_retraction_id': propose_id, 
            'msg_id': message_id,
            'jingle_status': context.model.get('jingle_status'),
            'template_hook': 'getJingleTemplate'
        }
        context.model.messages.create(attrs);
    }

I borrowed this code from a single file called “utils.js” which as the name suggests contains all the miscellaneous functions of a plugin that are needed for it to function. It doesn’t take much thinking to realize how big the problem becomes once the codebase is large enough. I must say it’s thanks to my mentor, I was able to differentiate the two sides, and i am now able to move on. Though, I still get confused but fortunately, I feel like its becoming more infrequent.

Ohh, and by the way, the create function creates an instance of the message model, and if you didn’t understand this statement, I highly recommend going through the backbone.js documentation .

So, lessons to learn:

• Comment or possibly document your code from day one.
• Don’t keep random variable names.
• Speak up to your mentor!! Period. I can assure you a lot of JC’s time could have been saved had I spoken up about my thought process sooner.

Ahemmm….. let’s move on now.

Message Chat History Rendering for Jingle

Now, when you get a missed call, you usually get a timestamp. It is no different in a jingle call, but I do need to have a discussion regarding it’s actual implementation with JC. The actual message content should be pretty straightforward and if you want to see how I implemented/am implementing it, I will straight up point towards JC’s explanation of it .

Non-Technical Corner of this blog

Hmmmm enough about the project, now for some unnecessary life updates. I will be leaving for my master’s program in a week’s time. My schedule is packed with various things right now. Going to a new country on your own is scary for the first time, especially when you know that there is no one who can help you there but GSoC seems like a perfect distraction from the nervousness. JC seems to be doing fine, speaking of whom, did I mention he took a hiatus last week? I really hope he enjoyed his time off. There were nights in the last week, which made me wonder if I did actually stress him out or something, but I am pretty sure I am just overthinking it. I value his patience out of all things and I am not joking when I say he has a lot of it. I mean, if I as a mentor would meet another PawBud, I would have probably quit by now and to be honest, that’s one of the million reasons why I am not a mentor right now. I feel so embarrassed about the little things JC has to repeat every time because I was distracted or too lazy to note them down. I hate inconsistency and love to be direct about things, so if you have made it this far, I would like to say that there is a good chance that this project might end with the implementation of XEP-0353 given my slow pace.

I do know that there are many people who are expecting this feature to be implemented, but yeah it is what it is. JC has somehow motivated me, to do what I do perfectly and I couldn’t agree more. Let’s see what the future holds now, I am giving it everything, and I will try to implement it as much as I can effectively.

Thanks for reading my blog.

Regards, PawBud

Monal version 5.2.0 has been released by the Monal development team! This release’s highlights are the new (private) push servers in Europe and the US, display of transferred files in app’s documents directory, and several fixes regarding encryption (OMEMO), QR code scanning, and onboarding. Besides, Monal also features a new webpage .

Psi+ 11.5.1634 (2022-07-11) has been released.

Servers

eturnal 1.10.0 , a STUN / TURN standalone server, has been released.

Openfire version 4.7.2 is out, stabilizing and fixing bugs, notably improving BOSH connections under load.

Push Notification Openfire plugin 0.9.1 was released with only one, but an important fix.

Version 1.8.3 of the Openfire REST API plugin is out too, extending MUC search and updating dependencies.

Libraries

libstrophe 0.12.1 , a lightweight XMPP client library written in C, has been released.

nbxmpp 3.1.1 has been released . This version comes with performance improvements and bug fixes.

The XMPP webhooks component has been updated to support more webhooks out of the box. Effectively, this component replaces proprietary tools such as Slack with a better option based on open code and open protocols, fully under control of its users. It now has:

• Richer messages for GitLab events (labels, time spent, etc.)
• Support for Stripe events, including optional (but recommended) signature verification.
• Support for SMS to URL Forwarder , a simple but effective SMS forwarder application for Android. This is handy for those with a second or third phone and it’s also used to showcase some of the new features .
• Integration with Nextcloud via Flow Webhooks .

Paul Schaub wrote a short blog post about their recent progress towards adding Web-of-Trust support to PGPainless. With release 1.3.2, the OpenPGP library got support for creating signatures on third-party certificates, which will help users to build their trust network.

xmpp-dns, a tool to check XMPP SRV records, was released in version 0.3.0 , bringing support for DNS over TLS (DoT) and for setting a custom DNS server.

Extensions and specifications

Developers and other standards experts from around the world collaborate on these extensions, developing new specifications for emerging practices, and refining existing ways of doing things. Proposed by anybody, the particularly successful ones end up as Final or Active - depending on their type - while others are carefully archived as Deferred. This life cycle is described in XEP-0001 , which contains the formal and canonical definitions for the types, states, and processes. Read more about the standards process . Communication around Standards and Extensions happens in the Standards Mailing List ( online archive ).

xmpp.org features a page about XMPP RFCs as well.

Proposed

The XEP development process starts by writing up an idea and submitting it to the XMPP Editor. Within two weeks, the Council decides whether to accept this proposal as an Experimental XEP.

In this blog, I will discuss my GSoC project, and post an update about the work done since the GSoC contribution period started. Ok, so I would like to split the whole project in two phases, with the first GSoC evaluation (29th July) as being the divider. Since it’s only been three weeks, I will only write about the first phase of the project.

About my project

• Expected Hours: 175 Hrs(Medium Project)
  • Adding support for Audio/Video Communication via Jingle.
  • Deliverables / Expected Results:
    • The goal is to create a Converse plugin that adds the ability to make one-on-one audio/video calls from Converse
    • The audio/video calls must be compatible with other XMPP clients such as Conversations .

Jingle protocol works something like this:

In short it signals WebRTC to start/end or modify the status of a session.

Proposed Plan

The first phase, as it stands, will consist of the UI implementation, it’s associated tests and implementaion of XEP 0353 . I genuinely thought that I would be done with the UI implementation till now, but choosing a UI can be surprisingly tough. Given the deadline, I want to make sure that I complete the implementation of the project in time, so for now we (me & my mentor JC) decided to implement a decent looking UI that would be enough to cover all the edge cases and functionality of the project.

UI

Here is a screenshot which shows the current UI.

Do mind the spacing between the Call Initiated text and the End Call button. The call can simply be ended after clicking either the end call button or the call button in the toolbar. Having said that, I presented Discord’s UI to my mentor and he seemed to like it.

Although, we plan to build something much more simpler for converse, it’s good to have a long term vision for this feature.

Tests

As on this date of writing this blog, I am working on integrating XEP 0353. The XEP makes it easier to keep track of my progress since it splits the feature into sections.

You can track my progress through this Pull Request

Hi, I am PawBud. I will be working as a GSoC Contributor with XSF. To know more about my project kindly read this blog . Feel free to contact me through my email to ask me anything you want!

Before I start, I feel that some things that I am going to write in this blog might offend someone. Kindly note that these thoughts are my own . Once again you are free to contact me through my email if you have anything to say, I would be happy to hear your thoughts.

On-Boarding Experience with XSF & Community Bonding Period

Well, I must say, this is unlike any technical internship that you will experience. The level of attention and support that you will get from the organization admins and your project mentors from day 1 is genuinely surprising. I mean, I started having weekly calls with my mentor before the coding period even began, and I am still quite thankful that my mentor(s) spent their time to guide me. Believe it or not, as soon as the results were announced and I saw my name, my first reaction was “oops, well this is bad”. I wasn’t ready for it! Meeting JC (my primary mentor) definitely helped me a lot during the community bonding period. Turns out not everyone does feel the same (thanks to Patiga, I knew about this). Still, from my past experience in internships, I do believe that self-doubt is something that our present-day society profits from, and it is something that one can’t afford if one wants to improve.

I wanted to spend as much time with the source code as I could but my university exams did not allow me to do so. I managed to work on some minor issues though, but I still feel that I need to put in as much work as I can. As of writing this blog, it’s the second week of GSoC. I have to work on designing and implementing a UI for the jingle call modal and will hopefully be done with that and the tests, by the end of this week.

Why Choose GSoC & specifically XSF?

Ok, this is an interesting one, I still remember the special treatment I received from the whole community once the GSoC results were announced. I think Eddie instantly shared the results with the community through the XSF GSoC group chat, Twitter and a couple of other XSF social media pages. I genuinely feel pampered by the overwhelming support of the community, but I am so proud that I chose GSoC over a usual company internship.

I took a course on software engineering during my sophomore year, and until now I have never ever seen/experienced its concepts being implemented. In Converse, I learned more about the applications of test-driven software development in 2 weeks than I ever did during my whole semester. Turns out, that practising a technique is actually the best way to learn it. The fact that my mentor takes out his time which he could very easily spend on developing Converse, just to guide me through the smallest of obstructions, is what really makes this whole thing special. No manager or supervisor in any company is going to give you this kind of attention! Period.

There is this book called Zucked by Roger McNamee. For those of you who haven’t read it here is a gist:- Roger was one of the initial investors of Facebook and a mentor to Mark Zuckerberg. Throughout the book, he explains how Facebook turned into an evil giant, and how the guilt he feels that he could not stop Zuckerberg and Facebook from pivoting to its present-day state. My hate for social media giants like Instagram, Facebook and Twitter, started after I graduated from Secondary School, this was because I started watching a lot of technology-related youtube channels and understood how toxic these social media giants actually are and how they exploit human psychology by giving instant gratification, and blah blah blah. I must say, I was infuriated and disgusted that all this time, I was just a product of these social media giants.

That mentality has grown stronger over the years and yes, I am not on any social media except Reddit, which I occasionally use to text my friends. Hence, XSF was a no-brainer for me, plus I wanted to learn Javascript well, so I only submitted one proposal, which was for Converse.

This was a personal and a non-technical blog post. To be honest, I am still figuring out how to write blogs, as this is my first blog post. I think I will start writing more technical and project-related blog posts after this.

Acknowledgement

In conclusion, I would like to thank my Mentors ( JC & Vanitas), Eddie (XSF GSoC Admin), Patiga (Co-contributor for XSF) and the whole XSF community for putting their trust in me. I would also like to take this opportunity to thank Zerefwayne & Yash Rathore for guiding me in the journey leading up to me getting selected as a contributor for XSF. I look forward to learning from all of you henceforth the GSoC period is finished.

For those of you who could not make it to GSoC with any organization including XSF

Remember, open source is not GSoC. I would honestly still contribute to various organizations, had I not gotten selected to GSoC, because it’s fun! Imagine writing code that is used by potentially millions of users daily. All those late-night hotfixes and mistakes that you do, do become good memories and of course, you get to learn a lot. The open source community is so friendly, that I have yet to see organizations that have core contributors who do not support newcomers.

GSoC should be a side goal in my opinion. If you get selected, that’s good for you. If you don’t get selected, you haven’t lost anything, you simply gain knowledge and contributions.

The Google Summer of Code 2022 is about to lift off and coding starts soon! The XSF has not just been accepted (again!) as a hosting organization for XMPP projects, we also can welcome two new contributors who will work on open-source software projects in the XMPP environment! We have updated our designated web-page for the Google Summer of Code 2022 accordingly.

The XMPP projects at Google Summer of Code 2022

So, please welcome Patiga and PawBud as new contributors! It is really great that you chose XMPP for your coding adventure!

• Patiga will work on more flexible file transfers in Dino . Mentors will be fiaxh and Marvin W. - many thanks to both of you!
  • Resource-wise, messenger applications tend to be on the lightweight side of the spectrum. This drastically changes when file transfers are added to the equation. File transfers can arbitrarily increase resource-usage, both on network and data storage aspects. To alleviate this issue, stateless file sharing empowers the user to make informed decisions on which files to download. Deliverables:
    • Unified handling of HTTP and Jingle (peer-to-peer) file transfers
    • Enable sending metadata alongside files
    • Thumbnail previews for images
• PawBud will work towards adding support for A/V communication via Jingle in ConverseJS . Mentors will be JC Brand and vanitasvitae - many thanks to both of you, too!
  • The idea is to add support for Audio & Video communication through the Jingle protocol. The goal is to create a Converse plugin that adds the ability to make one-on-one audio/video calls from Converse. The audio/video calls will be compatible with other XMPP clients.
