Only considers the closure in term of `Realisation`, ignores all the
opaque inputs.
Dunno whether that’s the nicest solution, need to think it through a bit
Align all the worker protocol with `buildDerivation` which inlines the
realisations as one opaque json blob.
That way we don’t have to bother changing the remote store protocol
when the definition of `Realisation` changes, as long as we keep the
json backwards-compatible
Move the `closure` logic of `computeFSClosure` to its own (templated) function.
This doesn’t bring much by itself (except for the ability to properly
test the “closure” functionality independently from the rest), but it
allows reusing it (in particular for the realisations which will require
a very similar closure computation)
When you have a symlink like:
/tmp -> ./private/tmp
you need to resolve ./private/tmp relative to /tmp’s dir: ‘/’. Unlike
any other path output by dirOf, / ends with a slash. We don’t want
trailing slashes here since we will append another slash in the next
comoponent, so clear s like we would if it was a symlink to an absoute
path.
This should fix at least part of the issue in
https://github.com/NixOS/nix/issues/4822, will need confirmation that
it actually fixes the problem to close though.
Introduced in f3f228700a.
Accidentally removed in ca96f52194. This
caused `nix run` to systematically fail with
```
error: app program '/nix/store/…' is not in the Nix store
```
~/.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.
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.
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:
```
