Eelco Dolstra 75efa42134 Move <nix/fetchurl.nix> into the nix binary 
This makes the statically linked nix binary just work, without needing
any additional files.

Eelco Dolstra 724b7f4fb6 Don't log from inside the logger 
This deadlocks ProgressBar, e.g.

  # nix run --impure --no-substitute --store '/tmp/nix2?store=/foo' --expr 'derivation { builder = /nix/store/zi90rxslsm4mlr46l2xws1rm94g7pk8p-busybox-1.31.1-x86_64-unknown-linux-musl/bin/busybox; }'

Add explicit allRefs = true; argument to fetchGit 
Sometimes it's necessary to fetch a git repository at a revision and
it's unknown which ref contains the revision in question. An example
would be a Cargo.lock which only provides the URL and the revision when
using a git repository as build input.

However it's considered a bad practice to perform a full checkout of a
repository since this may take a lot of time and can eat up a lot of
disk space. This patch makes a full checkout explicit by adding an
`allRefs` argument to `builtins.fetchGit` which fetches all refs if
explicitly set to true.

Closes #2409

Provide a more meaningful error-message for builtins.fetchGit if a revision can't be checked out 
A common pitfall when using e.g. `builtins.fetchGit` is the `fatal: not
a tree object`-error when trying to fetch a revision of a git-repository
that isn't on the `master` branch and no `ref` is specified.

In order to make clear what's the problem, I added a simple check
whether the revision in question exists and if it doesn't a more
meaningful error-message is displayed:

```
nix-repl> builtins.fetchGit { url = "https://github.com/owner/myrepo"; rev = "<commit not on master>"; }
moderror: --- Error -------------------------------------------------------------------- nix
Cannot find Git revision 'bf1cc5c648e6aed7360448a3745bb2fe4fbbf0e9' in ref 'master' of repository 'https://gitlab.com/Ma27/nvim.nix'! Please make sure that the rev exists on the ref you've specified or add allRefs = true; to fetchGit.
```

Closes #2431

John Ericson 1a1af75338 Overhaul store subclassing 
We embrace virtual the rest of the way, and get rid of the
`assert(false)` 0-param constructors.

We also list config base classes first, so the constructor order is
always:

  1. all the configs
  2. all the stores

Each in the same order

Replace Value type setters with mk* functions 
Move clearValue inside Value

mkInt instead of setInt

mkBool instead of setBool

mkString instead of setString

mkPath instead of setPath

mkNull instead of setNull

mkAttrs instead of setAttrs

mkList instead of setList*

mkThunk instead of setThunk

mkApp instead of setApp

mkLambda instead of setLambda

mkBlackhole instead of setBlackhole

mkPrimOp instead of setPrimOp

mkPrimOpApp instead of setPrimOpApp

mkExternal instead of setExternal

mkFloat instead of setFloat

Add note that the static mk* function should be removed eventually

Fix the detection of already built drv outputs
 2020-12-17 14:12:28 +01:00
regnat 4d45839499 Fix the detection of already built drv outputs 
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.
