~/.bashrc should be sourced first in the rc script so that PATH &
other env vars give precedence over the bashrc PATH.
Also, in my bashrc I alias rm as:
alias rm='rm -Iv'
To avoid running this alias (which shows ‘removed '/tmp/nix-shell.*'),
we can just prefix rm with command.
For whatever reason, many programs trying to access SystemVersion.plist
also open SystemVersionCompat.plist; this includes Python code and
coreutils’ `cat(1)` (but not the native macOS `/bin/cat`). Illustratory
`dtruss(1m)` output:
open("/System/Library/CoreServices/SystemVersion.plist\0", 0x0, 0x0) = 3 0
open("/System/Library/CoreServices/SystemVersionCompat.plist\0", 0x0, 0x0) = 4 0
I assume this is a Big Sur change relating to the 10.16.x/11.x
version compatibility divide and that it’s something along the lines of
a hook inside libSystem.
Fixes a lot of sandboxed package builds under Big Sur.
When we don’t have enough free job slots to run a goal, we put it in
the waitForBuildSlot list & unlock its output locks. This will
continue from where we left off (tryLocalBuild). However, we need the
locks to get reacquired when/if the goal ever restarts. So, we need to
send it back through tryToBuild to get reqacquire those locks.
I think this bug was introduced in
https://github.com/NixOS/nix/pull/4570. It leads to some builds
starting without proper locks.
When commit 233b61d3d6 (#4224) renamed
@binaryTarball_${system}@ to @tarballHash_${system}@, it updated this
reference for every platform except Darwin.arm64.

Similar to the nar-info disk cache (and using the same db).
This makes rebuilds muuch faster.
- This works regardless of the ca-derivations experimental feature.
I could modify the logic to not touch the db if the flag isn’t there,
but given that this is a trash-able local cache, it doesn’t seem to be
really worth it.
- We could unify the `NARs` and `Realisation` tables to only have one
generic kv table. This is left as an exercise to the reader.
- I didn’t update the cache db version number as the new schema just
adds a new table to the previous one, so the db will be transparently
migrated and is backwards-compatible.
Fix#4746
This was previously done in https://github.com/NixOS/nix/pull/4515 but
got clobbered away in https://github.com/NixOS/nix/pull/4594.
--------------------------------------------------------------------------------
This fixes an issue where derivations with a primary output that is
not "out" would fail with:
$ nix profile install nixpkgs#sqlite
error: opening directory '/nix/store/2a2ydlgyydly5czcc8lg12n6qqkfz863-sqlite-3.34.1-bin': No such file or directory
This happens because while derivations produce every output when
built, you might not have them if you didn't build the derivation
yourself (for instance, the store path was fetch from a binary cache).
This uses outputName provided from DerivationInfo which appears to
match the first output of the derivation.
This looks a lot better (and is also more semantically meaningful).
Since this list is generated in a Nix expression, I don't think using
HTML here is going to be the thing that puts people off modifying this
part of the documentation!
I guess I misunderstood John's initial explanation about why wildcards
for outputs are sent to older stores[1]. My `nix-daemon` from 2021-03-26
also has version 1.29, but misses the wildcard[2]. So bumping seems to
be the right call.

Starting in macOS 11, the on-disk dylib bundles are no longer available,
but nixpkgs needs to be able to keep compatibility with older versions
that require `/usr/lib/libSystem.B.dylib` in `__impureHostDeps`. Allow
it to keep backwards compatibility with these versions by marking these
dependencies as optional.
Fixes#4658.
As described in #4745 it's otherwise fairly hard to understand where
this is coming from. Say you have an expression which uses e.g.
`types.package`:
``` nix
{ outputs = { self, nixpkgs }: {
packages.x86_64-linux.hello = let
foo = nixpkgs.lib.evalModules {
modules = [
{
options.foo.bar = with nixpkgs.lib; mkOption { type = types.package; };
}
{
foo.bar = ./.;
}
];
};
in builtins.trace foo.config.foo.bar.outPath nixpkgs.legacyPackages.x86_64-linux.hello;
defaultPackage.x86_64-linux = self.packages.x86_64-linux.hello;
};
}
```
Then you'll get an error trace like this:
```
