Adam Joseph dc205c75a2 src/libexpr/primops.cc: correct definition for intersectAttrs
The current definition of `intersectAttrs` is incorrect:

> Return a set consisting of the attributes in the set e2 that also exist in the
> set e1.

Recall that (Nix manual, section 5.1):

> An attribute set is a collection of name-value-pairs (called attributes)

According to the existing description of `intersectAttrs`, the following should
evaluate to the empty set, since no key-value *pair* (i.e. attribute) exists in
both sets:

```
builtins.intersectAttrs { x=3; } {x="foo";}
```

And yet:

```
nix-repl> builtins.intersectAttrs { x=3; } {x="foo";}
{ x = "foo"; }
```

Clearly the intent here was for the *names* of the resulting attribute set to be
the intersection of the *names* of the two arguments, and for the values of the
resulting attribute set to be the values from the second argument.

This commit corrects the definition, making it match the implementation and intent.

Matthew Bauer 6e049ae607 Allow pass max-silent-time and build-poll-interval to daemon untrusted
These settings seem harmless, they control the same polling
functionality that timeout does, but with different behavior. Should
be safe for untrusted users to pass in.

John Ericson a2a8cb10ac Dodge "trusted" vs "trustworthy" by being explicit
Hopefully this is best!

John Ericson 752f967c0f "valid signature" -> "trustworthy signature"
I just had a colleague get confused by the previous phrase for good
reason. "valid" sounds like an *objective* criterion, e.g. and *invalid
signature* would be one that would be trusted by no one, e.g. because it
misformatted or something.

What is actually going is that there might be a signature which is
perfectly valid to *someone else*, but not to the user, because they
don't trust the corresponding public key. This is a *subjective*
criterion, because it depends on the arbitrary and personal choice of
which public keys to trust.

I therefore think "trustworthy" is a better adjective to use. Whether
something is worthy of trust is clearly subjective, and then "trust"
within that word nicely evokes `trusted-public-keys` and friends.

nix repl: warn if creating dir for history fails
The history is not critical to the functionality of nix repl, so it's
enough to warn here, rather than refuse to start if the directory Nix
thinks the history should live in can't be created.

Remove a useless debug message in filetransfer.cc
Remove the `verify TLS: Nix CA file = 'blah'` message that Nix used to print when fetching anything as it's both useless (`libcurl` prints the same info in its logs) and misleading (gives the impression that a new TLS connection is being established which might not be the case because of multiplexing. See #7011 )

Adam Joseph b3550d9179 libexpr/fetchurl.nix: allow __impure fetch
This commit adds an optional `__impure` parameter to fetchurl.nix, which allows
the caller to use `libfetcher`'s fetcher in an impure derivation.  This allows
nixpkgs' patch-normalizing fetcher (fetchpatch) to be rewritten to use nix's
internal fetchurl, thereby eliminating the awkward "you can't use fetchpatch
here" banners scattered all over the place.

Ana Hobden 8ebdbeb257 Add fish suport to installer
Before this patch, installing Nix using the Fish shell did not
work because Fish wasn't configured to add Nix to the PATH. Some
options in #1512 offered workarounds, but they typically involve
extra plugins or packages.

This patch adds native, out-of-the-box support for the Fish shell.

Note that Fish supports a `conf.d` directory, which is intended
for exactly use cases like this: software projects distributing
shell snippets. This patch takes advantage of it. The installer
doesn't append any Nix loader behavior to any Fish config file.
Because of that, the uninstall process is smooth and a reinstall
obliterates the existing nix.fish files that we place instead of
bothering the user with a backup / manual removal.

Both single-user and multi-user cases are covered. It has been
tested on Ubuntu, and a Mac with MacPorts, homebrew, and the
Fish installer pkg.

Closes #1512

Andrew Brooks 84fe75a12a Keep created temp dirs inside store, but protect from GC
Implements the approach suggested by feedback on PR #6994, where
tempdir paths are created in the store (now with an exclusive lock).

As part of this work, the currently-broken and unused
`createTempDirInStore` function is updated to create an exclusive lock
on the temp directory in the store.

The GC now makes a non-blocking attempt to lock any store directories
that "look like" the temp directories created by this function, and if
it can't acquire one, ignores the directory.

Eelco Dolstra 27be54ca53 nix develop: Ignore stdenv's $SHELL
Stdenv sets this to a bash that doesn't have readline/completion
support, so running 'nix (develop|shell)' inside a 'nix develop' gives
you a crippled shell. So let's just ignore the derivation's $SHELL.

This could break interactive use of build phases that use $SHELL, but
they appear to be fairly rare.

'nix-shell --run'.
