regnat f24f0888f9 Document the new store hierarchy 2020-09-16 13:53:09 +02:00
regnat 1129913c4e fixup! Correctly call all the parent contructors of the stores 2020-09-16 13:53:09 +02:00
regnat 7f103dcddd Properly filter the stores according to their declared uriSchemes
When opening a store, only try the stores whose `uriSchemes()` include
the current one
2020-09-16 13:53:09 +02:00
regnat 5895184df4 Correctly call all the parent contructors of the stores
Using virtual inheritance means that only the default constructors of
the parent classes will be called, which isn't what we want
2020-09-16 13:53:09 +02:00
regnat 22afa8fb4d Separate store configs from the implems
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
2020-09-16 13:53:08 +02:00
regnat 3b57181f8e Separate the instantiation and initialisation of the stores
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)

regnat fa32560169 Fix the registration of stores 2020-09-16 13:53:08 +02:00
regnat 7d5bdf8b56 Make the store plugins more introspectable
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.

John Ericson 4720853129 Make system-features a store setting
This seems more correct. It also means one can specify the features a
store should support with --store and remote-store=..., which is useful.
I use this to clean up the build remotes test.

This assumption is broken by CA derivations. Making a PR now to do the
breaking daemon change as soon as possible (if it is already too late,
we can bump protocol intead).

regnat d38f860c3e Add a way to get all the outputs of a derivation with their label
Generalize `queryDerivationOutputNames` and `queryDerivationOutputs` by
adding a `queryDerivationOutputMap` that returns the map
`outputName=>outputPath`

(not that this is not equivalent to merging the results of
`queryDerivationOutputs` and `queryDerivationOutputNames` as sets don't
preserve the order, so we would end up with an incorrect mapping).

squash! Add a way to get all the outputs of a derivation with their label

Rename StorePathMap to OutputPathMap

I’m not 100% sure this is wanted since it kind of makes everything
have to know about ca even if they don’t really want to. But it also
make things easier in dealing with looking up ca.

Eelco Dolstra 759947bf72 StorePath: Rewrite in C++
On nix-env -qa -f '<nixpkgs>', this reduces maximum RSS by 20970 KiB
and runtime by 0.8%. This is mostly because we're not parsing the hash
part as a hash anymore (just validating that it consists of base-32
characters).

Also, replace storePathToHash() by StorePath::hashPart().

Matthew Bauer c214cda940 Correctly substitute from different storeDir
Originally, the test was only checking for different “real” storeDir.
That’s an easy case to handle, but the much harder one is if different
virtual store dirs are used. To do this, we need the SubstitutionGoal
to know about the ca, so it can recalculate the path to copy it over.
An important note here is that the store path passed to copyStorePath
needs to be one for srcStore - so that queryPathInfo works properly.

This also adds an error message when the store path from queryPathInfo
is different from the one we requested.
