OpenSMTPD table protocol changes, now with the backstory

by
Regular readers will be aware that OpenBSD ships with its own mail server implementation, OpenSMTPD in its base system.

In a recent message to the tech@ mailing list, Omar Polo (op@) asked for comments or oks for a patches implementing a change of table protocols. A little later, Gilles Chehade (gilles@) posted the backstory to the misc@opensmtpd.org mailing list with the backstory for this change.

The message follows in full below (apparently the otherwise fine marc.info archive site no longer archives the list):

Subject: smtpd: change the table protocol

Hello,

This is a copy of a mail I sent to OpenBSD hackers a few days ago so you are aware of work
being done on OpenSMTPD by Omar Polo.

~~~

TL;DR: proposal to change table backends wire protocol to one that's closer to filters, it
       has proven to work for years now, comes with many benefits and it is a very trivial
       change that we can pull in a handful of hours:

Dude, Where’s My Archive?

by

TWIF generated on Thursday, 02 May 2024, Week 18

F-Droid core

Four weeks ago in the 14-th TWIF we announced the start of 1.20 testing and the repository management improvements that it brings. Over the years, the concept of a “repository archive” kinda stayed the same. Basically, instead of serving the users the full list of all the versions of all the apps, we give them only the latest three versions for each app, as users will just update to the latest one anyway. This keeps an index update easy to download, and this was improved again a couple of years ago by offering diff-updates (not the full index, just the difference compared to your local index), so if you update once a week you’ll end up downloading 200Kb or less.

Since the Archive will collect old versions continuously, its size grows each cycle, and the index as expected, making working with it a heavy task for your device. For this reason we don’t encourage its use unless it’s really needed, eg. for running on old Android versions, and to disable it when done.

As the Client focus is to draw users to the actual main repo, and not to emphasis the Archive, with the latest repository management design it was decided to treat Archive as an option that users can toggle on, instead of having a separate repo entry. This toggle is in the repo details, “in the bottom of a locked filing cabinet stuck in a disused lavatory with a sign on the door saying ‘Beware of the Leopard.’“, 🙂 oh, I mean under the mirror list. This list is under a work in progress redesign of its own, so it’s a bit finicky to scroll right now, leaving even astute Android users to wonder how an Archive can be added or used.

To be fair, the linked Fedi post above has this information in the first picture, but we understand that we’ve looked a lot at these strings and we are biased to consider them “good enough”. One reason to test these changes as early as possible is to gather feedback from users. If you have thoughts on a better wording, feel free to ping us.

Community News

Aurora Store was updated to 4.4.4 and will deemed stable in the next-next index update. You can update now manually if you wish.

Grazer Linuxtage Schedule has changed its application identifier due to some, ahem, alternative centralized store policy. Its users are advised to uninstall and install the new app aptly named: Grazer Linuxtage

NewPipe is reproducible again and was updated to 0.27.0 fixing a lot of bugs users were waiting for months already. We hope future versions get delivered faster.

RISC OS Open 5.30 arrives with Raspberry Pi Wi-Fi support

by
This is, in a way, a mature OS with an ecosystem and an aftermarket. (Which, we feel we must explicitly spell out, means that quite a few of those third-party applications and drivers will cost you money.) There are emulators that will let you run 20th century Acorn apps that you can find online, but this isn’t an emulated vintage environment like Amiga Forever. It’s not meant for running games from thirty years ago. This is a native bare-metal OS, built on 1980s roots but updated for 21st century hardware. It’s also not an experimental project with little practical use, like Redox OS or Serenity OS, interesting though those are. ↫ Liam Proven at The Register I grew up with RISC OS and still run a RISC OS machine to this day. As Liam Proven explains affectionately in this article, while as an operating system it’s missing many features we now take for granted (memory protection, pre-emptive multitasking, compositing), some of the user interface ideas it implements still manage to feel advanced compared to modern-day desktops (no need for menu bars, no clunky file dialogues, elegant mouse button assignments). The fact it’s found a home on the Raspberry Pi and continues to support an active community is testament to its enduring appeal and the amazing work of the RISC OS Open project. Some additional notes from Thom: this new release supports 7 ARM platforms, most notably the Raspberry Pi Zero, 1, 2, 3 and 4 (but not the 5), and it even supports WiFi on the 3 and 4, which is an absolutely incredible achievement. The number of fixed bugs and addressed issues is massive, and there’s even more to come later during the year, as The Register’s article notes. I was waiting on this release to spur me on to buy a new Raspberry Pi (my only other Pi is our Pi-Hole), so I’ll definitely be on the lookout for a good deal. This release deserves my full attention for OSNews.
