Emacs 31 changes[3] the behavior of extending info path for installed elisp pkgs at startup. Previously, it called function `info-initialize' and extended `Info-directory-list'. Now, it does not call function `info-initialize' and instead extends `Info-default-directory-list' in most cases. The new behavior does not work if Emacs is started with an environment variable INFOPATH without a trailing ":". This is tracked in upstream Emacs bug#81105[1]. Also note that Emacs 31 changes the order of startup operations[2] to this: 1. load site-start.el 2. load early-init.el 3. active packages 4. load init.el 5. load default.el 6. handle CLI args such as --eval This patch works around bug#81105[1] by adding a trailing ":" to INFOPATH when needed in site-start.el. An alternative workaround is to call function `info-initialize' in site-start.el, which basically (not 100%, due to the startup order changes) keeps the old behavior of Emacs 30. Both workarounds invalidate part of `Info-directory-list' docstring. The workaround used in this patch makes users unable to ignore default info path items[4] like `Info-default-directory-list' when initializing `Info-directory-list'. The alternative one basically always ignores `Info-default-directory-list' when initializing `Info-directory-list' because `info-initialize` is called too early and `Info-default-directory-list' has no value yet. Note that the alternative workaround does allow users to decide if they want other default info path items[4] such as `configure-info-directory'. In addition, the workaround used in this patch should be faster than the alternative one. Both workarounds can be undone by users. To undo the one used in this patch, users can removed the added ":" of INFOPATH in early-init.el. For the alternative workaround, users need to re-initialize info path after package activation like this: (progn (setq Info-directory-list nil) (info-initialize)).

Other Project Repositories
The sources of all official Nix-related projects are in the NixOS organization on GitHub. Here are some of the main ones:
- Nix - the purely functional package manager
- NixOps - the tool to remotely deploy NixOS machines
- nixos-hardware - NixOS profiles to optimize settings for different hardware
- Nix RFCs - the formal process for making substantial changes to the community

Continuous Integration and Distribution
Nixpkgs and NixOS are built and tested by our continuous integration system, Hydra.
- Continuous package builds for unstable/master
- Continuous package builds for the NixOS 26.05 release
- Tests for unstable/master
- Tests for the NixOS 26.05 release
Artifacts successfully built with Hydra are published to cache at https://cache.nixos.org/. When successful build and test criteria are met, the Nixpkgs expressions are distributed via Nix channels.
Contributing
Nixpkgs is among the most active projects on GitHub. While thousands of open issues and pull requests might seem like a lot at first, it helps to consider it in the context of the scope of the project. Nixpkgs describes how to build tens of thousands of pieces of software and implements a Linux distribution. The GitHub Insights page gives a sense of the project activity.
Community contributions are always welcome through GitHub Issues and Pull Requests.
