Don't add the whole store to sandbox-paths unconditionally. Exposing
the entire store defeats the purpose of sandboxing, and when the test
store is the same as the system store (NixOS VM), it causes an obscure
"Permission denied" error.
Only add sandbox-paths when not on NixOS, indicating a separate test
store that needs access to system store build tools.
All current NixOS functional VM tests have a daemon as root with the
tests running as different unprivileged users.
The new `functional_unprivileged-daemon` test runs the daemon and the
nix functional tests as separate unprivileged users.
Users may want to run an unprivileged daemon on non-NixOS systems
where the administrator does not fully trust nix, but multiple users
want to use nix for their own purposes. It could also be useful in
concert with an overlay-mount store, where the nix daemon cannot
modify the derivations used by the system, and thus a nix vulnerability
would not lead to root code execution.
When running nix as an unprivileged user it may not be able to write to
all paths in the nix store. Ignore deletion failures to fix tests that
run `nix-collect-garbage` in this configuration.

We are now seeing. I guess we are out with the cache. When the API responds with 418 (I'm a teapot)
it seems like the only reasonable solution is to oblige.
error: unable to download 'http://127.0.0.1:37515/7ms9f25xyxavf32pvdc3vb28nzzmkbn3.narinfo': HTTP error 418
response body:
GitHub API error: GitHub Actions Cache throttled Magic Nix Cache. Not trying to use it again on this run.
This PR follows the same approach as #15043 and the
[`LogFileSettings`](https://github.com/NixOS/nix/pull/15051)
extraction:
- `GCSettings` struct inherits from virtual `Config`
- `Settings` privately inherits from it
- Accessed through `getGCSettings()`
The new method on `LocalStoreConfig` anticipates on making these
settings per-store. 0b606aad46 added both
the autoGC and periodic wakeups, which is why we think they are related.
When an upload fails with a transient HTTP error (e.g., S3 rate limiting
with HTTP 503), retries would fail with "curl error: Failed to open/read
local data from file/application" because the upload source was already
exhausted from the previous attempt.
Restart the source in init() to ensure it's at the beginning for both
first attempts (no-op) and retries (necessary fix).
Fixes: #15023
Progress on #5638
Replace the SQLite constructor's mode parameter with a Settings struct
that includes both the open mode and useWAL flag. This makes the
dependency on useSQLiteWAL explicit at call sites rather than having
it read from the global settings inside the constructor.
All call sites now explicitly pass settings.useSQLiteWAL, preparing
for downstream work where stores can pass their own settings instead
of relying on the global.
Some S3-compatible services (like GCS) modify the Accept-Encoding header
in transit, which breaks AWS SigV4 signature verification since curl's
implementation signs all headers including Accept-Encoding.
Fixes: #15019
It is possible that the `nix` executable is installed but not `nix-env`
(this may be unusual but for example in Fedora we have a separate
`nix-legacy` subpackage, which includes the `nix-env` symlink).
The current error message:
```
$ nix config check --verbose
Running checks against store uri: local
[FAIL] Multiple versions of nix found in PATH:
```
when there is no nix-env in PATH is confusing.
This change makes the error message precise for the missing nix-env case.
Introduce a new `Signature` struct that represents a cryptographic
signature
along with the key name that produced it. This provides:
- Structured representation instead of colon-separated strings
- Type-safe parsing with `Signature::parse()`
- Serialization with `to_string()`
- JSON serialization/deserialization
- Batch parsing with `parseMany<Container>()`
- Batch serialization with `toStrings()`
This is scaffolding for future changes that will use this type
throughout the codebase.
This will once and for all get rid of all double-quoting issues. On windows the quoting
is doubly bad because it escaped all \ to \\, which is very bad for error messages. In
order to prevent future regression std::filesystem::path formatting now must use a special
type PathFmt (like Magenta). In the future we could even change how we render filesystem paths.
