2021-06-11Add a ca-derivations required machine featureregnat
Make ca-derivations require a `ca-derivations` machine feature, and ca-aware builders expose it. That way, a network of builders can mix ca-aware and non-ca-aware machines, and the scheduler will send them in the right place.

2021-05-26Make `copyPaths` copy the whole realisations closureregnat
Otherwise registering the realisations on the remote side might fail as it now expects a complete closure
2021-04-05Rename BuildableJohn Ericson
2021-04-05Use `BuildableReq` for `buildPaths` and `ensurePath`John Ericson
This avoids an ambiguity where the `StorePathWithOutputs { drvPath, {} }` could mean "build `brvPath`" or "substitute `drvPath`" depending on context. It also brings the internals closer in line to the new CLI, by generalizing the `Buildable` type is used there and makes that distinction already. In doing so, relegate `StorePathWithOutputs` to being a type just for backwards compatibility (CLI and RPC).
2021-04-05Move `StorePathWithOutputs` into its own header/fileJohn Ericson
In the following commits it will become less prevalent.

2021-02-25Don't crash when copying realisations to a non-ca remoteregnat
Rather throw a proper exception, and catch&log it on the client side
2021-02-25Use `RealisedPath`s in `copyPaths`regnat
That way we can copy the realisations too (in addition to the store paths themselves)
2021-02-19Register the realisations for unresolved drvsregnat
Once a build is done, get back to the original derivation, and register all the newly built outputs for this derivation. This allows Nix to work properly with derivations that don't have all their build inputs available − thus allowing garbage collection and (once it's implemented) binary substitution

Fix some logging with ca derivations

Don't only show the name of the output, but also the derivation to which this output belongs (as otherwise it's very hard to track back what went wrong)

Use the fs accessor for readInvalidDerivation
2020-12-17Fix the detection of already built drv outputsregnat
PRs #4370 and #4348 had a bad interaction in that the second broke the fist one in a not trivial way. The issue was that since #4348 the logic for detecting whether a derivation output is already built requires some logic that was specific to the `LocalStore`. It happens though that most of this logic could be upstreamed to any `Store`, which is what this commit does.
2020-12-16Better detect when `buildPaths` would be a no-opregnat
`buildPaths` can be called even for stores where it's not defined in case it's bound to be a no-op. The “no-op detection” mechanism was only detecting the case wher `buildPaths` was called on a set of (non-drv) paths that were already present on the store. This commit extends this mechanism to also detect the case where `buildPaths` is called on a set of derivation outputs which are already built on the store. This only works with the ca-derivations flag. It could be possible to extend this to also work without it, but it would add quite a bit of complexity, and it's not used without it anyways.
2020-12-15Use the fs accessor for readInvalidDerivationregnat
Extend `FSAccessor::readFile` to allow not checking that the path is a valid one, and rewrite `readInvalidDerivation` using this extended `readFile`. Several places in the code use `readInvalidDerivation`, either because they need to read a derivation that has been written in the store but not registered yet, or more generally to prevent a deadlock because `readDerivation` tries to lock the state, so can't be called from a place where the lock is already held. However, `readInvalidDerivation` implicitely assumes that the store is a `LocalFSStore`, which isn't always the case. The concrete motivation for this is that it's required for `nix copy --from someBinaryCache` to work, which is tremendously useful for the tests.
2020-12-09libstore/openStore: fix stores with IPv6 addressesMaximilian Bosch
In `nixStable` (2.3.7 to be precise) it's possible to connect to stores using an IPv6 address: nix ping-store --store ssh://root@2001:db8::1 This is also useful for `nixops(1)` where you could specify an IPv6 address in `deployment.targetHost`. However, this behavior is broken on `nixUnstable` and fails with the following error: $ nix store ping --store ssh://root@2001:db8::1 don't know how to open Nix store 'ssh://root@2001:db8::1' This happened because `openStore` from `libstore` uses the `parseURL` function from `libfetchers` which expects a valid URL as defined in RFC2732. However, this is unsupported by `ssh(1)`: $ nix store ping --store 'ssh://root@[2001:db8::1]' cannot connect to 'root@[2001:db8::1]' This patch now allows both ways of specifying a store (`root@2001:db8::1`) and also `root@[2001:db8::1]` since the latter one is useful to pass query parameters to the remote store. In order to achieve this, the following changes were made: * The URL regex from `url-parts.hh` now allows an IPv6 address in the form `2001:db8::1` and also `[2001:db8::1]`. * In `libstore`, a new function named `extractConnStr` ensures that a proper URL is passed to e.g. `ssh(1)`: * If a URL looks like either `[2001:db8::1]` or `root@[2001:db8::1]`, the brackets will be removed using a regex. No additional validation is done here as only strings parsed by `parseURL` are expected. * In any other case, the string will be left untouched. * The rules above only apply for `LegacySSHStore` and `SSHStore` (a.k.a `ssh://` and `ssh-ng://`). Unresolved questions: * I'm not really sure whether we want to allow both variants of IPv6 addresses in the URL parser. However it should be noted that both seem to be possible according to RFC2732: > This document incudes an update to the generic syntax for Uniform > Resource Identifiers defined in RFC 2396 [URL]. It defines a syntax > for IPv6 addresses and allows the use of "[" and "]" within a URI > explicitly for this reserved purpose. * Currently, it's not supported to specify a port number behind the hostname, however it seems as this is not really supported by the URL parser. Hence, this is probably out of scope here.
2020-12-02Sink: Use std::string_viewEelco Dolstra
2020-11-17Merge pull request #4180 from Ma27/ssh-ng-substituteEelco Dolstra
Allow substituting paths when building remotely using `ssh-ng://`
2020-11-17CleanupEelco Dolstra
2020-11-05Allow substituting paths when building remotely using `ssh-ng://`Maximilian Bosch
Until now, it was not possible to substitute missing paths from e.g. `https://cache.nixos.org` on a remote server when building on it using the new `ssh-ng` protocol. This is because every store implementation except legacy `ssh://` ignores the substitution flag passed to `Store::queryValidPaths` while the `legacy-ssh-store` substitutes the remote store using `cmdQueryValidPaths` when the remote store is opened with `nix-store --serve`. This patch slightly modifies the daemon protocol to allow passing an integer value suggesting whether to substitute missing paths during `wopQueryValidPaths`. To implement this on the daemon-side, the substitution logic from `nix-store --serve` has been moved into a protected method named `Store::substitutePaths` which gets currently called from `LocalStore::queryValidPaths` and `Store::queryValidPaths` if `maybeSubstitute` is `true`. Fixes #2770
2020-10-29Generalize extra-* settingsEelco Dolstra
This removes the extra-substituters and extra-sandbox-paths settings and instead makes every array setting extensible by setting "extra-<name> = <value>" in the configuration file or passing "--<name> <value>" on the command line.

2020-09-16Properly filter the stores according to their declared uriSchemesregnat
When opening a store, only try the stores whose `uriSchemes()` include the current one
2020-09-16Separate store configs from the implemsregnat
Rework the `Store` hierarchy so that there's now one hierarchy for the store configs and one for the implementations (where each implementation extends the corresponding config). So a class hierarchy like ``` StoreConfig-------->Store | | v v SubStoreConfig----->SubStore | | v v SubSubStoreConfig-->SubSubStore ``` (with virtual inheritance to prevent DDD). The advantage of this architecture is that we can now introspect the configuration of a store without having to instantiate the store itself
2020-09-16fixup! Separate the instantiation and initialisation of the storesregnat
2020-09-16Separate the instantiation and initialisation of the storesregnat
Add a new `init()` method to the `Store` class that is supposed to handle all the effectful initialisation needed to set-up the store. The constructor should remain side-effect free and just initialize the c++ data structure. The goal behind that is that we can create “dummy” instances of each store to query static properties about it (the parameters it accepts for example)
2020-09-16Fix the registration of storesregnat
2020-09-16Make the store plugins more introspectableregnat
Directly register the store classes rather than a function to build an instance of them. This gives the possibility to introspect static members of the class or choose different ways of instantiating them.
