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.

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.

Docs: Add nix develop --command entry
Add example of nix develop being used to execuate a series of script
commands. This is common when doing things like CI/CD, and should be
represented in the official documentation.

Also useful for people looking for the 'nix develop' equivalent of
'nix-shell --run'.

Matthew Bauer 102434e4cb Disable SA_RESTART for some signals on macOS
Disables the SA_RESTART behavior on macOS which causes:

> Restarting of pending calls is requested by setting the SA_RESTART bit
> in sa_flags. The affected system calls include read(2), write(2),
> sendto(2), recvfrom(2), sendmsg(2) and recvmsg(2) on a communications
> channel or a slow device (such as a terminal, but not a regular file)
> and during a wait(2) or ioctl(2).

From: https://man.openbsd.org/sigaction#SA_RESTART

This being set on macOS caused a bug where read() calls to the daemon
socket were blocking after a SIGINT was received. As a result,
checkInterrupt was never reached even though the signal was received
by the signal handler thread.

On Linux, SA_RESTART is disabled by default. This probably effects
other BSDs but I don’t have the ability to test it there right now.

Matthew Bauer 4894e567fb Don’t readDerivation if impure derivations feature is disabled
readDerivation is pretty slow, and while it may not be significant for
some use cases, on things like ghc-nix where we have thousands of
derivations is really slows things down.

So, this just doesn’t do the impure derivation check if the impure
derivation experimental feature is disabled. Perhaps we could cache
the result of isPure() and keep the check, but this is a quick fix to
for the slowdown introduced with impure derivations features in 2.8.0.

This matches the behavior of bash. We don’t want to add a space after
completion on attrs. Uses -S.

Switches to new compadd style comppletions instead of _describe.
Shouldn’t have any negative issues from what I can tell.

Matthew Bauer f4d7208e23 Update boehmgc-coroutine-sp-fallback.diff for darwin
The darwin_stop_world implementation is slightly different. sp goes to
altstack_lo instead of lo in this case. Assuming that is an
implementation detail.

But the fix is the same, when we detect alstack_lo outside of the
expected stack range, we reset it to hi - stack_limit.

Here stack_limit is calculated with pthread_get_stacksize_np since
that is the BSD equivalent to pthread_attr_getstacksize.
