By appending a colon to MANPATH NIX_MAN_DIR gets prepended to the
final MANPATH before default search paths.
This makes man still consider default search paths, but prefers
NIX_MAN_DIR (if it exists).
It still makes sense to point NIX_MAN_DIR to a correct location
by moving man pages build from nix-manual.man to nix-cli.man, but
this should fix most common use-cases where nix is installed globally.
(cherry picked from commit 95f16a3275)
Exposed for Hydra. We could make it fancier but with (a) new store
settings (b) switch to `ssh-ng://` both in the works, it doesn't seem
worth it.
(cherry picked from commit 94a7c34b2f)
It is unused in Nix currently, but will be used in Hydra. This reflects
what Hydra does in https://github.com/NixOS/hydra/pull/1387.
We may probably to use it more widely for better SSH store performance,
but this needs to be subject to more testing before we do that.

Otherwise we may accidentally update a lock when we shouldn't.
Fixes#12445.

E.g. in a derivation attribute `foo = ./bar`, if ./bar is a symlink,
we should copy the symlink to the store, not its target. This restores
the behaviour of Nix <= 2.19.
(cherry picked from commit 26b87e78b5)
If we previously fetched by revision, the output of "git ls-remote"
won't start with the expected line like
ref: refs/heads/master HEAD
but will be something like
5c4410e3b9891c05ab40d723de78c6f0be45ad30 refs/heads/5c4410e3b9891c05ab40d723de78c6f0be45ad30
This then causes Nix to treat that revision as a refname, which then
leads to warnings like
warning: could not update cached head '5c4410e3b9891c05ab40d723de78c6f0be45ad30' for 'file:///tmp/repo'
(cherry picked from commit c8b22643ba)
This causes Git to create a local ref named refs/head/<rev>, e.g.
$ git -C ~/.cache/nix/gitv3/11irpim06vj4h6c0w8yls6kx4hvl0qd0gr1fvk47n76g6wf1s1vk ls-remote --symref .
5c4410e3b9891c05ab40d723de78c6f0be45ad30 refs/heads/5c4410e3b9891c05ab40d723de78c6f0be45ad30
7f6bde8a20de4cccc2256f088bc5af9dbe38881d refs/heads/7f6bde8a20de4cccc2256f088bc5af9dbe38881d
which confuses readHead(), leading to errors like
fatal: Refusing to point HEAD outside of refs/
warning: could not update cached head 'd275d93aa0bb8a004939b2f1e87f559f989453be' for 'file:///tmp/repo'
(cherry picked from commit ee9fa0d360)
Git interprets them as part of the file name, so passing parameters
like 'rev' breaks. Only relevant for testing (when _NIX_FORCE_HTTP is
set) and local bare repos.
(cherry picked from commit 9f72d5bce9)
In general we should set the path display prefix on the inner
accessor, so we now pass the display prefix to getAccessor().
(cherry picked from commit 3032512425)
Fixes messages like 'copying /tmp/repo/tmp/repo to the store'. The
PosixSourceAccessor already sets the prefix. Setting the prefix twice
shouldn't be a problem, but GitRepoImpl::getAccessor() returns a
wrapped accessor so it's not actually idempotent.
(cherry picked from commit 102d90ebf0)
The main improvement is that the new message gives an example of a path
that is referenced, which should make it easier to track down. While
there, I also clarified the wording, saying exactly why the paths in
question were illegal.

This does not include any automation for the release branch, but
is based on the configuration of https://github.com/NixOS/nix/pull/12349
pre-commit run -a nixfmt-rfc-style
I started getting these warnings `warning: download buffer is full; consider increasing the 'download-buffer-size' setting` but the documentation does not make it obvious what unit of measurement it accepts.
1. Fix this eval error:
https://hydra.nixos.org/jobset/nix/master#tabs-errors
The dev package output (actually a separate derivation) needs to skip
this for cross just as the main package output does.
2. Deduplicate libs attrset and list.
3. Move `nix-functional-tests` to `checkInputs`.
With the Meson build system, we no longer need a `check` vs
`install-check` distinction, so it is simpler to just keeep
everything in one place.
This allows RemoteStore::addMultipleToStore() to free the Source
objects early (and in particular the associated sinkToSource()
buffers). This should fix#7359. For example, memory consumption of
nix copy --derivation --to ssh-ng://localhost?remote-store=/tmp/nix --derivation --no-check-sigs \
/nix/store/4p9xmfgnvclqpii8pxqcwcvl9bxqy2xf-nixos-system-...drv
went from 353 MB to 74 MB.
Fixes
$ nix copy --derivation --to /tmp/nix /nix/store/...
error: cannot enqueue a work item while the thread pool is shutting down
The ThreadPoolShutDown exception was hiding the reason for the thread
pool shut down, e.g.
error: cannot add path '/nix/store/03sl46khd8gmjpsad7223m32ma965vy9-fix-static.patch' because it lacks a signature by a trusted key
nix-env can read priorities from a derivations meta attributes, but this
only works when installing a nix expression.
nix-env can also install bare store paths, however meta attributes are
not readable in that case. This means that a store path can not be
installed with a specific priority.
Some cases where it is advantageous to install a store path: a remote
host following a `nix copy`, or any time you want to save some
evaluation time and happen to already know the store path.
This PR addresses this shortcoming by adding a --priority flag to
nix-env --install.
