git fetcher: invoke diff instead of diff-index diff-index operates on the view that git has of the working tree, which might be outdated. The higher-level diff command does this automatically. This change also adds handling for submodules. fixes #4140 Alternative fixes would be invoking update-index before diff-index or matching more closely what require_clean_work_tree from git-sh-setup.sh does, but both those options make it more difficult to reason about correctness.

builtins.fetchGit: Fix build when fetching a git worktree Worktrees[1] are a feature of git which allow you to check out a ref in a different directory. While playing around with flakes I realized that git repositories in a worktree checkout break when trying to build a flake: ``` $ git worktree add ../nixpkgs-flakes nixpkgs-flakes $ cd ../nixpkgs-flakes $ nix build .#hello error: opening directory '/home/ma27/Projects/nixpkgs-flakes/.git/refs/heads': Not a directory ``` This issue has been fixed by determining with `git rev-parse --git-common-dir` where the actual `.git` directory is. Please note that this issue only exists on the `flakes` branch, fetching worktree checkouts with Nix master seems to work fine. [1] https://git-scm.com/docs/git-worktree

This patch implements a new git-fetcher based on `fetchTree` by incorporating the following changes: * Removed the original `fetchGit`-implementation and replaced it with an alias on the `fetchTree` implementation. * Ensured that the `git`-fetcher from `libfetchers` always computes a content-hash and returns an "empty" revision on dirty trees (the latter one is needed to retain backwards-compatibility). * The hash-mismatch error in the fetcher-API exits with code 102 as it usually happens whenever a hash-mismatch is detected by Nix. * Removed the `flakes`-feature-flag: I didn't see a reason why this API is so tightly coupled to the flakes-API and at least `fetchGit` should remain usable without any feature-flags. * It's only possible to specify a `narHash` for a `git`-tree if either a `ref` or a `rev` is given[4]. * It's now possible to specify an URL without a protocol. If it's missing, `file://` is automatically added as it was the case in the original `fetchGit`-implementation.

Add pure evaluation mode In this mode, the following restrictions apply: * The builtins currentTime, currentSystem and storePath throw an error. * $NIX_PATH and -I are ignored. * fetchGit and fetchMercurial require a revision hash. * fetchurl and fetchTarball require a sha256 attribute. * No file system access is allowed outside of the paths returned by fetch{Git,Mercurial,url,Tarball}. Thus 'nix build -f ./foo.nix' is not allowed. Thus, the evaluation result is completely reproducible from the command line arguments. E.g. nix build --pure-eval '( let nix = fetchGit { url = https://github.com/NixOS/nixpkgs.git; rev = "9c927de4b179a6dd210dd88d34bda8af4b575680"; }; nixpkgs = fetchGit { url = https://github.com/NixOS/nixpkgs.git; ref = "release-17.09"; rev = "66b4de79e3841530e6d9c6baf98702aa1f7124e4"; }; in (import (nix + "/release.nix") { inherit nix nixpkgs; }).build.x86_64-linux )' The goal is to enable completely reproducible and traceable evaluation. For example, a NixOS configuration could be fully described by a single Git commit hash. 'nixos-rebuild' would do something like nix build --pure-eval '( (import (fetchGit { url = file:///my-nixos-config; rev = "..."; })).system ') where the Git repository /my-nixos-config would use further fetchGit calls or Git externals to fetch Nixpkgs and whatever other dependencies it has. Either way, the commit hash would uniquely identify the NixOS configuration and allow it to reproduced.

Restore backwards-compat for current `builtins.fetchGit` If a repo is dirty, it used to return a `rev` object with an "empty" sha1 (0000000000000000000000000000000000000000). Please note that this only applies for `builtins.fetchGit` and *not* for `builtins.fetchTree{ type = "git"; }`.

git fetcher: invoke diff instead of diff-index diff-index operates on the view that git has of the working tree, which might be outdated. The higher-level diff command does this automatically. This change also adds handling for submodules. fixes #4140 Alternative fixes would be invoking update-index before diff-index or matching more closely what require_clean_work_tree from git-sh-setup.sh does, but both those options make it more difficult to reason about correctness.

git fetcher: improve check for valid repository The .git/refs/heads directory might be empty for a valid usable git repository. This often happens in CI environments, which might only fetch commits, not branches. Therefore instead we let git itself check if HEAD points to something that looks like a commit. fixes #5302

Require shallow clones to be requested explicitly If you do a fetchTree on a Git repository, whether the result contains a revCount attribute should not depend on whether that repository happens to be a shallow clone or not. That would complicate caching a lot and would be semantically messy. So applying fetchTree/fetchGit to a shallow repository is now an error unless you pass the attribute 'shallow = true'. If 'shallow = true', we don't return revCount, even if the repository is not actually shallow. Note that Nix itself is not doing shallow clones at the moment. But it could do so as an optimisation if the user specifies 'shallow = true'. Issue #2988.
