My SNAFU was that I assumed that all the `Value *`s we put in
`attrsSeen` are already reachable (which they are), but I forgot about
the `elems` pointer in `ListBuilder`.
Fixes#11547.
(cherry picked from commit 0c2fdd2f3c)
The impending release of macOS 15 Sequoia will break many existing nix
installs on macOS, which may lead to an increased number of people who
are looking to try to reinstall Nix without noticing the open/pinned
issue (#10892) that explains the problem and outlines how to migrate
existing installs.
These admonitions are a short-term measure until we are over the hump
and support volumes dwindle.

When we're fetching by rev, that file doesn't necessarily exist, and we
don't care about it anyway.

On macOS, `mkdir("x/')` behaves differently than `mkdir("x")` if `x` is
a dangling symlink (the formed succeed while the latter fails). So make
sure we always strip the trailing slash.

The current backport action cannot automerge because
the github action bot does not trigger github CI actions.
Mergify instead does not have this limitation and can also
use a merge queue.
On top we have now a declarative configuration to allow
contributers to add new tests to required without having access
to the github org.
An example pull request and backport can be seen here:
https://github.com/Mic92/nix-1/pull/4
and here:
https://github.com/Mic92/nix-1/pull/5
To complete the setup the mergify app must be enabled for this repository.
It's already installed in the nixos organization for nixos-hardware and
other repositories.

downloadTarball() is used by `-I foo=<url>` etc. fetchToStore() needs
the accessor to have a fingerprint to enable caching.
Fixes#11271.
(cherry picked from commit 9f6ee93f48)
Starting in macOS 15 Sequoia, macOS daemon UIDs are encroaching on our
default UIDs of 301-332. This commit relocates our range up to avoid
clashing with the current UIDs of 301-304 and buy us a little time
while still leaving headroom for people installing more than 32 users.

This broke in #11005. Any number of PathSubstitutionGoals would
be woken up by a single build slot becoming available. If there
are a lot of substitution goals active, this could lead to us
running out of file descriptors (especially on macOS where the
default limit is 256).
