Allow `-` and `.` in the RFC schemes as stated by

Practically, this is needed so that `ssh-ng` is a valid URI scheme

5895184df4 Correctly call all the parent contructors of the stores

Using the `*Config` class hierarchy
 2020-09-16 13:53:08 +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

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)

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.

Fix unspecified behaviour in readStorePathCAMap 
When deploying a Hydra instance with current Nix master, most builds
would not run because of errors like this:

  queue monitor: error: --- Error --- hydra-queue-runner
  error: --- UsageError --- nix-daemon
  not a content address because it is not in the form '<prefix>:<rest>': /nix/store/...-somedrv

The last error message is from parseContentAddress, which expects a
colon-separated string, however what we got here is a store path.

Looking at the worker protocol, the following message sent to the Nix
daemon caused the error above:

  0x1E -> wopQuerySubstitutablePathInfos
  0x01 -> Number of paths
  0x16 -> Length of string
  "/nix/store/...-somedrv"
  0x00 -> Length of string
  ""

Looking at writeStorePathCAMap, the store path is indeed the first field
that's transmitted. However, readStorePathCAMap expects it to be the
*second* field *on my machine*, since expression evaluation order is a
classic form of unspecified behaviour[1] in C++.

This has been introduced in https://github.com/NixOS/nix/pull/3689,
specifically in commit 66a62b3189.

626200713b Pass all args when auto-calling a function with an ellipsis 
The command line options --arg and --argstr that are used by a bunch of
CLI commands to pass arguments to top-level functions in files go
through the same code-path as auto-calling top-level functions with
their default arguments - this, however, was only passing the arguments
that were *explicitly* mentioned in the formals of the function - in the
case of an as-pattern with an ellipsis (eg args @ { ... }) extra passed
arguments would get omitted. This fixes that to instead pass *all*
specified auto args in the case that our function has an ellipsis.
