Example:
$ nix build --show-trace
error: unable to download 'https://api.github.com/repos/NixOS/nixpkgs/commits/no-such-branch': HTTP error 422 ('')
response body:
{
"message": "No commit found for SHA: no-such-branch",
"documentation_url": "https://docs.github.com/rest/reference/repos#get-a-commit"
}
… while fetching the input 'github:NixOS/nixpkgs/no-such-branch'
… while updating the flake input 'nixpkgs'
… while updating the lock file of flake 'git+file:///home/eelco/Dev/nix'

It appears as through the fetch attribute, which
is simply a variant with 3 elements, implicitly
converts boolean arguments to integers. One must
use Explicit<bool> to correctly populate it with
a boolean. This was missing from the implementation,
and resulted in clearly boolean JSON fields being
treated as numbers.

libc++10 seems to be stricter on what it allows in variant conversion.
I'm not sure what the rules are here, but this is the minimal change
needed to get through the compilation errors.

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

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

Without setting HGPLAIN, the user's environment leaks into
hg invocations, which means that the output may not be in the
expected format.
HGPLAIN is the Mercurial-recommended solution for this in that
it's intended for uses by scripts and programs which are looking
to parse Mercurial's output in a consistent manner.

Fixes:
$ nix build --store /tmp/nix /home/eelco/Dev/patchelf#hydraJobs.build.x86_64-linux
warning: Git tree '/home/eelco/Dev/patchelf' is dirty

Add some internal documentation for flake support objects.
|
|
This matches the already-existing `local-fs-store.cc`.

This was useful for an experiment with building Nix as a single
compilation unit. It's not very useful otherwise but also doesn't
hurt...

This change provides support for using access tokens with other
instances of GitHub and GitLab beyond just github.com and
gitlab.com (especially company-specific or foundation-specific
instances).
This change also provides the ability to specify the type of access
token being used, where different types may have different handling,
based on the forge type.
|
|
Completes the change begun in commit 56f1e0d to consistently use the
"host" attribute for "github" and "gitlab" inputs instead of a "url"
attribute.
|
|
This reduces compilation time by ~15 seconds (CPU time).
Issue #4045.

Since 108debef6f703aa3ca1f6d6c45428880624ec6f8 we allow a
`url`-attribute for the `github`-fetcher to fetch tarballs from
self-hosted `gitlab`/`github` instances.
However it's not used when defining e.g. a flake-input
foobar = {
type = "github";
url = "gitlab.myserver";
/* ... */
}
and breaks with an evaluation-error:
error: --- Error --------------------------------------nix
unsupported input attribute 'url'
(use '--show-trace' to show detailed location information)
This patch allows flake-inputs to be fetched from self-hosted instances
as well.

`nix flake info` calls the github 'commits' API, which requires
authorization when the repository is private. Currently this request
fails with a 404.
This commit adds an authorization header when calling the 'commits' API.
It also changes the way that the 'tarball' API authenticates, moving the
user's token from a query parameter into the Authorization header.
The query parameter method is recently deprecated and will be disallowed
in November 2020. Using them today triggers a warning email.

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.

Don't try to parse signature check as commit timestamp
|
|
When the log.showSignature git setting is enabled, the output of
"git log" contains signature verification information in addition to the
timestamp GitInputScheme::fetch wants:
$ git log -1 --format=%ct
gpg: Signature made Sat 07 Sep 2019 02:02:03 PM PDT
gpg: using RSA key 0123456789ABCDEF0123456789ABCDEF01234567
gpg: issuer "user@example.com"
gpg: Good signature from "User <user@example.com>" [ultimate] 1567890123
1567890123
For folks that had log.showSignature set, this caused all nix operations
on flakes to fail:
$ nix build
error: stoull
