This label will be useful for constructing queries to find backportable PRs.
Specifically, those should omit both automatic backports and
"backports reviewed" PRs.
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
In order for the script not be sourced multiple times by the same shell
instance, `__ETC_PROFILE_NIX_SOURCED` needs to be set with a `--global`
flag.
Both files are almost identical. And style differences make it harder
to see what is actually different and keep them in sync, when it is
required.
`nix-profile.fish` and part of `nix-profile-daemon.fish` use 4 space
indentation. Which is also the indentation that the fish shell
documentation is using.
Reformatting a chunk of `nix-profile-daemon.fish` from 2 space
indentation to 4 space indentation for consistency.
- Multiple choices of stdenv are handled more consistently, especially for the dev
shells which were previously not done correctly.
- Some stray nix code was moving into the `packaging` directory
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.
Since ff8e2fe84e, 'path:' URLs on the
CLI are interpreted as relative to the current directory of the user,
not the path of the flake we're overriding.
