Fixes #3389.

|
|
|
|
This was broken by 22a754c091f765061f59bef5ce091268493bb138.

In
nix-instantiate --dry-run '<nixpkgs/nixos/release-combined.nix>' -A nixos.tests.simple.x86_64-linux
this reduces time spent in unparse() from 9.15% to 4.31%. The main
culprit was appending characters one at a time to the destination
string. Even though the string has enough capacity, push_back() still
needs to check this on every call.
|
|
The evaluator was spending about 1% of its time compiling a small
number of regexes over and over again.
|
|
|
|
It failed on names like '/nix/store/9ip48nkc9rfy0a4yaw98lp6gipqlib1a-'.

nix-shell: clean up the tmpDir and escape variables
|
|
The problem fixed: each nix-shell invocation creates a new temporary
directory (`/tmp/nix-shell-*`) and never cleans up.
And while I'm here, shellescape all variables inlined into the rcfile.
See what might happen without escaping:
$ export TZ="';echo pwned'"
$ nix-shell -p hello --run hello
pwned
Hello, world!

Fix PR_SET_PDEATHSIG results in Broken pipe (#2395)
|
|
Necessary since we're now propagating boehm-gc.

Fixes #3363.
|
|
The flag is `--pure-eval`, which can be found by looking at the test suite; it
should be in the notes describing the feature as well, since otherwise users may
assume this is referencing something like `nix-shell --pure`.
|
|
The ssh client is lazily started by the first worker thread, that
requires a ssh connection. To avoid the ssh client to be killed, when
the worker process is stopped, do not set PR_SET_PDEATHSIG.

Returning a nullable type in an optional is silly.

Remove #[macro_use]
|
|
As of Rust 2018, macro_use is no longer required in most circumstances.
I think it is generally a good idea to remove these when not needed, to
stop them from polluting the crate's global namespace.

ssh-store: add remote-store and remote-program query params
|
|
Brings the functionality of ssh-ng:// in sync with the legacy ssh://
implementation. Specifying the remote store uri enables various useful
things. eg.
$ nix copy --to ssh-ng://cache?remote-store=file://mnt/cache --all

structured-attrs: chown .attrs.* files to builder

Otherwise `chmod .`'ing the build directory doesn't work anymore, which
is done in nixpkgs if sourceRoot is set to '.'.

system
On a systemd-based Linux distribution: If the user has previously had multi-user Nix installed on the system, removed it and then reinstalled multi-user Nix again the old nix-daemon.service will still be running when `scripts/install-systemd-multi-user.sh` tries to start it which results in nothing being done and the old daemon continuing its run.
When a normal user then tries to use Nix through the daemon the nix binary will fail to connect to the nix-daemon as it does not belong to the currently installed Nix system. See below for steps to reproduce the issue that motivated this change.

build: remove warning when in sandboxing test mode
|
|
doc: touchup release notes for 2.3
|
|
- At the top of the release notes, we announce sandboxing is now enabled by default,
then at the bottom it says it's now disabled when missing kernel support. These
can be merged into one point for clarity.
- The point about `max-jobs` defaulting to 1 appears unrelated to sandboxing.
