[dasJ]

It's time for another feature freeze!

Let's clarify any blocking concerns for the 22.05 release in this thread, which will go live on May 30th.
Feature Freeze issue of th previous release: #140168

[nixos-discourse]

This issue has been mentioned on NixOS Discourse. There might be relevant details there:

https://discourse.nixos.org/t/22-05-feature-freeze/18453/1

[DianaOlympos]

For @NixOS/beam i do not think we have anything that could be blocking on the docket.

[peterhoeg]

For Crystal, we have the crystal-lang team. Two issues that I absolutely want to get in before 22.05 is released: - #164648 - #167044

[dasJ]

@peterhoeg Thanks, I added them to the Blockers project. If you want to add the team to the next announcement, you can just set the featureFreezePing flag in the list :)

[ryantm]

I'm not really up on what is going on with the docs themselves, but I'm not aware of anything blocking the technical aspect of generating the docs. I don't have much to report on progress with generating the docs either. mmdoc is now packaged in nixpkgs, but it still needs more work to be a polished solution.

[bobby285271]

No blockers for @NixOS/Pantheon, we are already shipping the latest Pantheon 6.1 and Pantheon 7 is not likely to happen in this release due to upstream delay.

[teto]

since I've noticed you started crossing topics:

• no blocker for the lua ecosystem
• for (neo)vim, there will be a neovim release in 2 weeks and I would like to merge update.py: updater vim updater #166941 . None should be an issue though, I've already updated the required dependencies for neovim master

[etu]

No blocker for PHP as far as I know :)

[drupol]

No blocker for PHP as far as I know :)

I think we should tackle this at the next version: #154774

[mweinelt]

Python is currently in a good state. We're doing regular package set updates and have one more cycle in #166489 that we'll hopefully get into the next staging cycle.

PyPy3 currently fails to build due to a regression after the zlib update. #167115

[etu]

No blocker for PHP as far as I know :)

I think we should tackle this at the next version: #154774

For sure, but we're too close to a release for that. We can do that right after branchoff which isn't relevant for this thread.

[SomeoneSerge]

On behalf of the newly created @NixOS/cuda-maintainers, we're finishing an important major bump (cudnn 7.6 -> 8.3, cuda 10.1 -> 11.4) that we'd like to get into the release. There are a few failing packages that hadn't been tested with CUDA until now, that we would like to meet the release in an already fixed state: #167068

P.S. Keep in mind we're just getting acquainted with the release process:)

[jtojnar]

For GNOME, we will want to include

• webkitgtk: 2.34.6 → 2.36.0 #166298
• nixos/gnome: set default wallpaper for dark mode as well #166096

And there are still some annoying regression. For some of them, we expect them to be fixed in GNOME 42.1 (April 23).

• One of those makes GNOME Shell crash when clicking close button in window overview (Activities): https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/5137 so we would want to update at least Shell and Mutter to 42.1. gnome.gnome-shell: 42.0 → 42.1 #171904
• Some NetworkManager VPN plug-ins do not support GTK 4 so when one tries to configure them in GNOME Settings, they will only see (Error: unable to load VPN connection editor). Not sure what to do about that. Perhaps we could merge nixos/networkmanager: Allow overriding installed plug-ins #164531 and do not include them by default, since they are unmaintained any way.

---

For docs, we want:

• nixos/man: prevent duplication of options #166509

[roberth]

• NixOS module system: no blocking issues.
  Infinisil and I have made some quality of life improvements that have been merged for some time. We'll take it easy until branch-off, as far as I'm concerned.

• dockerTools: also no blocking issues.

[Gabriella439]

No blocking issues for Dhall

[mweinelt]

The hydra package is currently failing to build which should be considered a blocker. Mostly expecting #160202 to get finished.

[jbedo]

No blockers for R

[bhankas]

Emacs 28.1 was released yesterday.

Announcement: https://lists.gnu.org/archive/html/emacs-devel/2022-04/msg00093.html
Release tar: https://git.savannah.gnu.org/cgit/emacs.git/snapshot/emacs-28.1.tar.gz

Perhaps @adisbladis can comment on requirement to be in the release.

[tfc]

No blockers for the integration test driver

[Synthetica9]

I'd really like to get #158175 fixed, but I'm not sure how feasible that is

[vcunat]

They sound like bugs, maybe the fixes will be quite simple. Overall I find it unlikely that the feature freeze applies there, with fixes hopefully possible to backport at any later point.

[Madouura]

We should probably ensure that #168303 is in 22.05, as it's a blocker for cross-compilation, in my case riscv64.

[mweinelt]

We should probably ensure that #168303 is in 22.05, as it's a blocker for cross-compilation, in my case riscv64.

Already part of #168737.

[adisbladis]

Regarding Emacs:
Emacs 28 was merged in #168076 which is great timing for the release. No blockers.

[siraben]

@CohenCyril @vbgl @Zimmi48 should we update the default version of Coq to the latest version (8.15)? No other blockers AFAIK.

[vbgl]

Yes. I’m working on it.

[adisbladis]

Enabling both libcontainer based software such as runc/podman and NixOS containers have been broken for years (#77925) and is fixed by moving configuration/state directories.

This is addressed by #87268 which should go in 22.05.

[jaen]

Apologies in advance if this is the wrong place to talk about this (whether this is considered a breaking change or a release-worthy topic) as I never participated in a release, but maybe it would be useful to get #170655 in? At least for me I couldn't get VAAPI working in Brave without those changes, so it might be useful for other people to have this working OOtB in 22.05?

[mweinelt]

Java/OpenJDK is pretty much unmaintained. We don't have OpenJDK 18. We do Have 17, 11 and 8 (all LTS). But we also Have 16, 15, 14, 13, 12.

#170825

@edwtjo @asbachb

[primeos]

We could also really need additional LLVM maintainers as we barely manage to keep things up-to-date and working.
I finally opened a dedicated issue regarding that (this was long overdue): #171047
(Sorry for hijacking this issue but this seems relevant in general (LLVM is a release critical package, llvmPackages_latest will already be outdated for 22.05 (#165701), and it will probably be worse for the next stable release if we don't find additional maintainers.)

[Madouura]

I know we're already in the 3rd stage of the release schedule, but I would highly recommend we include these commits in 22.05, even if potentially breaking.

• stdenv: use gcc11 for riscv #170991
• gcc: 11.2.0 -> 11.3.0 #170121

The GCC one is just a bugfix update, so should be fine, using GCC11 as default for riscv could potentially lead to unexpected behavior.
That said, it seems to only fix cross compiling and native compiling without side-effects from my own tests.

[vcunat]

These will be included. The minor update wouldn't be considered breaking anyway. Support for riscv in NixPkgs is... experimental?, so I think there it's fine. (Though I'm a bit doubtful about which riscv users will use stable?)

[SomeoneSerge]

A silly question: we branch off master, things that are now in master are included?

[ulrikstrid]

Does this need to be fixed before? #170897

[rnhmjoj]

A silly question: we branch off master, things that are now in master are included?

I think so: according to the release schedule, the branch off is supposed to occur on May 22.

[0x4A6F]

#73404 is blocking installation if config.boot.initrd.secrets is set.

[rnhmjoj]

I have a strange "not a git repo" error if I call sudo nixos-rebuild

See #169193

[jtojnar]

Regarding GNOME, there two more potentially problematic changes:

• adwaita-icon-theme removed majority of non-symbolic (colour) icons, which can make apps look inconsistent and in the worst case even make them unusable or crash (so far I have only encountered that in Meld). Probably something to note into ZHF.

• webkitgtk 3.36.0 does not render HTML on some systems e.g. in Evolution, gnucash, we need to check if 3.36.1 fixes that. Though that update breaks tests of liferea. And there is also this issue, which might require us to switch back to wpe renderer. I would really appreciate if someone could help with webkitgtk maintenance, as I currently lack time for that.

[dasJ]

Since a lot of people are (probably) subscribed to this issue due to @NixOS/nixpkgs-committers being pinged, I'd prefer this issue to only have a minimal conversation.
This conversation should be about what issues may or should be blocking the release, issue-specific topics should be discussed in the respective issues/pull requests.

Now about some of these comments:

• Document how to work around dynamic linking problems caused by glibc updates #170897 is important because I don't know if the next update will be during the 22.05 cycle. This is not blocking imo because documentation can easily be backported or just referenced from the unstable manual
• stage-1.nix / mktemp: failed to create directory via template ‘initrd-secrets.XXXXXXXXXX’: Read-only file system #73404 is important and I think a fix should go into the release while not blocking the release since this is not a regression
• git 2.35.2 breaks nixos-rebuild with flake repo owned by non-root user #169193 is important to flakes users. I'm not a flake user myself but from what I can gather from the issue, this should be backported in nix and not nixpkgs and is also a problem on 21.11 so not a regression
• I have no idea about the adwaita-icon-theme issue, me not caring about how consistent my icons look is a me-topic so the GNOME team should judge how critical the issue is
• The webkitgtk issue seems more severe and might be worth blocking the release (at least regarding more widely used tools), again the team should judge this. Some issues regarding this already seem to be resolved

This comment is my judgement on how blocking these issues are to the release. If you disagree with me, feel free to ping me in the respective issues to continue the discussion there rather than here.
Also, not being critical to the release does not mean I think these issues are not important. Something to consider is that we have a very well working backport wokflow now and some issues can be fixed during the release (like the documentation).

[NorfairKing]

I would love to get a new stack release into nixos 22.05: commercialhaskell/stack#5733 :D

[ners]

I would love to get 22.05 ISOs VM-friendly, but it seems stuck in merge limbo: #172668
