Before this change, processLine always uses the first character
as the start of the line. This cause whitespaces to matter at the
beginning of the line whereas it does not matter anywhere else.
This commit trims leading white spaces of the string line so that
subsequent operations can be performed on the string without explicitly
tracking starting and ending indices of the string.
This avoids an infinite loop in the final test in
tests/binary-cache.sh. I think this was only not triggered previously
by accident (because we were clearing wantedOutputs in between).
LocalStore::addToStore() since
79ae9e4558 expects a regular NAR hash,
rather than a NAR hash modulo self-references. Fixes#6300.
Also, makeContentAddressed() now rewrites the entire closure (so 'nix
store make-content-addressable' no longer needs '-r'). See #6301.
This allows closures to be imported at evaluation time, without
requiring the user to configure substituters. E.g.
builtins.fetchClosure {
storePath = /nix/store/f89g6yi63m1ywfxj96whv5sxsm74w5ka-python3.9-sqlparse-0.4.2;
from = "https://cache.ngi0.nixos.org";
}
Before the change lexter errors did not report the location:
$ nix build -f. mc
error: path has a trailing slash
(use '--show-trace' to show detailed location information)
Note that it's not clear what file generates the error.
After the change location is reported:
$ src/nix/nix --extra-experimental-features nix-command build -f ~/nm mc
error: path has a trailing slash
at .../pkgs/development/libraries/glib/default.nix:54:18:
53| };
54| src = /tmp/foo/;
| ^
55|
(use '--show-trace' to show detailed location information)
Here we see both problematic file and the string itself.
While `create_directories()` from install-multi-user.sh seems to already
create parts of the directory structure, it's marked as deprecated, and
it won't hurt also copying over the tmpfiles config and have it execute
once.
The new implementation relies on tab separting the hash and ref (this is how sourcehut does it). This fixes the integration test to use a tab instead of a space.
nix-daemon.socket is used to socket-activate nix-daemon.service when
/nix/var/nix/daemon-socket/socket is accessed.
In container usecases, sometimes /nix/var/nix/daemon-socket is
bind-mounted read-only into the container.
In these cases, we want to skip starting nix-daemon.socket.
However, since systemd 250, `ConditionPathIsReadWrite` is also not met
if /nix/var/nix/daemon-socket doesn't exist at all. This means, a
regular NixOS system will skip starting nix-daemon.socket:
> [ 237.187747] systemd[1]: Nix Daemon Socket was skipped because of a failed condition check (ConditionPathIsReadWrite=/nix/var/nix/daemon-socket).
To prevent this from happening, ship a tmpfiles file that'll cause the
directory to be created if it doesn't exist already.
In the case of NixOS, we can just add Nix to `systemd.tmpfiles.packages`
and have these files picked up automatically.
