Crucially this introduces BoehmGCStackAllocator, but it also
adds a bunch of wiring to avoid making libutil depend on bdw-gc.
Part of the solutions for #4178, #4200
This makes it even clearer which of the two hashes was specified in the
nix files. Some may think that "wanted" and "got" is obvious, but:
"got" could mean "got in nix file" and "wanted" could mean "want to see in nix file".
This makes it possible to have per-project configuration in flake.nix,
e.g. binary caches and other stuff:
nixConfig.bash-prompt-suffix = "[1;35mngi# [0m";
nixConfig.substituters = [ "https://cache.ngi0.nixos.org/" ];
The registry targets generally follow a URL formatting schema with
support for a query parameter of "?dir=subpath" to specify a sub-path
location below the URL root.
Alternatively, an absolute path can be specified. This specification
mode accepts the query parameter but ignores/drops it. It would
probably be better to either (a) disallow the query parameter for the
path form, or (b) recognize the query parameter and add to the path.
This patch implements (b) for consistency, and to make it easier for
tooling that might switch between a remote git reference and a local
path reference.

std::optional had redundant checks for whether it had a value.
An object is emplaced either way so it can be dereferenced
without repeating a value check
`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.
Otherwise the result of the printing can't be parsed back correctly by
Nix (because the unescaped `${` will be parsed as the begining of an
anti-quotation).
Fix#3989
The change in 626200713b didn't account
for when the number of auto arguments is bigger than the number of
formal arguments. This causes the following:
$ nix-instantiate --eval -E '{ ... }@args: args.foo' --argstr foo foo
nix-instantiate: src/libexpr/attr-set.hh:55: void nix::Bindings::push_back(const nix::Attr&): Assertion `size_ < capacity_' failed.
Aborted (core dumped)
This was broken in 50f13b06fb. Once
again it turns out that putting a bool in a std::variant is a bad
idea, since pointers get silently cast to them...
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.
Fixes#598
Fixes#3872.
This is a bit hacky. Ideally we would automatically re-evaluate the
failed attribute iff we need to print the error message (so in
commands like 'nix search' we wouldn't re-evaluate because we're
suppressing errors).
This fixes an error found in builtins.path that looks like:
store path mismatch in (possibly filtered) path added from '/private/tmp/nix-shell.CyXViH/nix-test/filter-source/filterin'
when no hash is specified
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"; }`.
