ci: Always run with sandbox, even on Darwin
And fix a test failure in the sandbox due to /home
existing on Darwin but not being accessible in the sandbox since it's a
symlink to /System/Volumes/Data/home, see
https://github.com/NixOS/nix/actions/runs/4205378453/jobs/7297384658#step:6:2127:

    C++ exception with description "error: getting status of /home/schnitzel/darmstadt/pommes: Operation not permitted" thrown in the test body.

On Linux this wasn't a problem because there /home doesn't exist in the sandbox

primops: lazy evaluation of replaceStrings replacements
The primop `builtins.replaceStrings` currently always strictly evaluates the
replacement strings, however time and space are wasted for their computation
if the corresponding pattern do not occur in the input string. This commit
makes the evaluation of the replacement strings lazy by deferring their
evaluation to when the corresponding pattern are matched and memoize the result
for efficient retrieval on subsequent matches.

The testcases for replaceStrings was updated to check for lazy evaluation
of the replacements. A note was also added in the release notes to
document the behavior change.

Théophane Hufschmitt d16a1994fb Properly report build errors on chrooted stores
When encountering a build error, Nix moves the output paths out of the
chroot into their final location (for “easier debugging of build
failures”). However this was broken for chroot stores as it was moving
it to the _logical_ location, not the _physical_ one.

Fix it by moving to the physical (_real_) location.

nix flake check: skip derivations for foreign systems (#7759)
`nix flake show` now skips derivations for foreign systems: https://github.com/NixOS/nix/pull/6988

This commit borrows from that to implement the same behavior for `nix flake check`.

John Ericson 9923403d90 Don't use store-api.hh in worker-protocol.hh
Using abstract types like can help cut down on compilation time, both
from scratch, and especially incremental builds during development. The
idea is that `worker-protocol.hh` can declare all the (de)serializers, but
only again abstract types; when code needs to use some (de)serializers, it can
include headers just for the data types it needs to (de)serialize.

`store-api.hh` in particular is a bit of a sledgehammer, and the data
types we want to serialize have their own headers.

John Ericson cb5052d98f Revert "Revert "Use template structs instead of phantoms""
This is the more typically way to do [Argument-dependent
lookup](https://en.cppreference.com/w/cpp/language/adl)-leveraging
generic serializers in C++. It makes the relationship between the `read`
and `write` methods more clear and rigorous, and also looks more
familiar to users coming from other languages that do not have C++'s
libertine ad-hoc overloading.

I am returning to this because during the review in
https://github.com/NixOS/nix/pull/6223, it came up as something that
would make the code easier to read --- easier today hopefully already,
but definitely easier if we were have multiple codified protocols with
code sharing between them as that PR seeks to accomplish.

If I recall correctly, the main criticism of this the first time around
(in 2020) was that having to specify the type when writing, e.g.
`WorkerProto<MyType>::write`, was too verbose and cumbersome. This is
now addressed with the `workerProtoWrite` wrapper function.

This method is also the way `nlohmann::json`, which we have used for a
number of years now, does its serializers, for what its worth.

This reverts commit 45a0ed82f0. That
commit in turn reverted 9ab07e99f5.

John Ericson e7c1113a37 Add test for downstreamPlaceholder
This is good in general, but in particular ensures when we heavily
refactor it in the next commit there is less likelihood for an
unintentional change in behavior to sneak in.

Merge pull request #8360 from obsidiansystems/worker-protocol.cc
Move `worker_proto` defs out of `remote-store.cc` to own file
2023-05-17 11:04:29 -04:00
John Ericson 904878d6d2 Move worker_proto defs out of remote-store.cc to own file
These items are not templates, and they declared in
`worker-protocol.hh`; therefore they should live in a
`worker-protocol.cc`.

Anything else needlessly diverges from convention. After all, it is not
like this code is only used in `remote-store.cc`; it is also used in
`daemon.cc`. There is no good reason to place it with the client
implementation or the server implementation when it used equally by
both.

Théophane Hufschmitt e997512523 Fix the printing of the installables on nix profile install conflict
- If the element comes from a flake, print the full flakeref (with the
  fragment part) and not just the reference to the flake itself
- If the element doesn't come from a flake, print its store path(s)

This is a bit too verbose, but has the advantages of being correct (and
not crashing), so it's strictly better than the previous situation

They were improperly added in 8a93b5a551.

They were not `.gitignore`d because they were stale in that commit --
build artifacts no longer used that name by then and so `.gitignore` was
updated accordingly.

John Ericson bbd7d5de09 Fix some bounds in rapid check instances
`inRange` is exclusive not inclusive:
https://github.com/emil-e/rapidcheck/blob/master/doc/generators.md#usage

Furthermore, use `std::variant_size_v` so we use the right number
automatically.

Finally, make the `switch` assert the discriminant is in bounds as
expected.

John Ericson f7c896cfd8 Dedup some markdown -> C++ big literal stuff in build system
This pattern rule was unwisely hidden in `src/libstore/local.mk`. Now it
is properly in `mk/` and we reuse it for the profile docs too.

John Ericson d2162e7acd Make more string values work as installables
As discussed in #7417, it would be good to make more string values work
as installables. That is to say, if an installable refers to a value,
and the value is a string, it used to not work at all, since #7484, it
works somewhat, and this PR make it work some more.

The new cases that are added for `BuiltPath` contexts:

- Fixed input- or content-addressed derivation:

  ```
  nix-repl> hello.out.outPath
  "/nix/store/jppfl2bp1zhx8sgs2mgifmsx6dv16mv2-hello-2.12"

  nix-repl> :p builtins.getContext hello.out.outPath
  { "/nix/store/c7jrxqjhdda93lhbkanqfs07x2bzazbm-hello-2.12.drv" = { outputs = [ "out" ]; }; }

  The string matches the specified single output of that derivation, so
  it should also be valid.

- Floating content-addressed derivation:

  ```
  nix-repl> (hello.overrideAttrs (_: { __contentAddressed = true; })).out.outPath
  "/1a08j26xqc0zm8agps8anxpjji410yvsx4pcgyn4bfan1ddkx2g0"

  nix-repl> :p builtins.getContext (hello.overrideAttrs (_: { __contentAddressed = true; })).out.outPath
  { "/nix/store/qc645pyf9wl37c6qvqzaqkwsm1gp48al-hello-2.12.drv" = { outputs = [ "out" ]; }; }
  ```

  The string is not a path but a placeholder, however it also matches
  the context, and because it is a CA derivation we have no better
  option. This should also be valid.

We may also want to think about richer attrset based values (also
discussed in that issue and #6507), but this change "completes" our
string-based building blocks, from which the others can be desugared
into or at least described/document/taught in terms of.

Progress towards #7417
