Currently root's shell is set to a path that does not exist; this change
sets it to the correct path to bash

This runs the installer in a QEMU VM. Unlike the old installer test
that ran inside a declaratively built RedHat/Debian image, this uses
an image from Vagrant.

Add Fish suport to the Nix installer
|

issue template: add feature label

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

RunPager: Stop the progress bar
|

In particular, the progress bar was interfering with 'less' rendering
in '--help' (e.g. run 'nix --help' and hit '/' to search).

Prevent tempdir from being GC-ed before addToStoreFromDump completes

each change should be an improvement, a label for that is redundant.

Docs: Add nix develop --command entry
|
|
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.

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.

Disable SA_RESTART for some signals on macOS
|
|
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'.

Installer: Reset the timestamps in the tarball

Set `HOME` var to `root`'s home when running `nix-store` as `root`

Don’t readDerivation if impure derivations feature is disabled
|
|
|
|
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.

This fixes issue 6823 by placing the tempdir used in LocalStore::addToStoreFromDump
outside the Nix store, where automatic GC is no longer a concern.

Don’t add a space after attrs completion in zsh
|
|
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.

Update boehmgc-coroutine-sp-fallback.diff for darwin
|

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.
