Previously, the build system used uname(1) output when it wanted to
check the operating system it was being built for, which meant that it
didn't take into-account cross-compilation when the build and host
operating systems were different.
To fix this, instead of consulting uname output, we consult the host
triple, specifically the third "kernel" part.
For "kernel"s with stable ABIs, like Linux or Cygwin, we can use a
simple ifeq to test whether we're compiling for that system, but for
other platforms, like Darwin, FreeBSD, or Solaris, we have to use a
more complicated check to take into account the version numbers at the
end of the "kernel"s. I couldn't find a way to just strip these
version numbers in GNU Make without shelling out, which would be even
more ugly IMO. Because these checks differ between kernels, and the
patsubst ones are quite fiddly, I've added variables for each host OS
we might want to check to make them easier to reuse.

Mac OS multi-user installations are currently broken because all requests
made by nix-daemon to the binary cache fail with:
```
unable to download ... Problem with the SSL CA cert (path? access rights?) (77).
```
This change ensures that the nix-daemon knows where to find the SSL CA cert file.
Fixes#2899 and #3261.

We're calling `wait4path` on the full, resolved `@bindir@/nix-daemon` path.
That means we're hardcoding something like:
/bin/wait4path /nix/store/zs9c5xhp3zv9p23qnjxp87nl5injsi1i-nix-2.3/bin/nix-daemon && /nix/var/nix/profiles/default/bin/nix-daemon
That seems unnecessarily fragile.
It might be better to wait4path on the path we intend to call.
(cherry picked from commit 8c4a5e7ba1)
On Catalina, the /nix filesystem might not be mounted at start time.
To avoid this service not starting, we need to keep the launch agent
outside of the Nix store. A wait4pid will hold for our /nix dir to be
mounted.
Fixes#3125.
(cherry picked from commit 0847f2f1b3)
When using a volume, the nix-daemon path may not exist. To avoid this
issue, we must use the wait4path tool. This should solve one of the
issues in multi-user on macOS Catalina.
Since macOS 10.14 this has become an error, causing problems if the
nix-daemon loads nix during substitution (this is a forked process).
Workaround for #2523.
We have automated builds at https://hub.docker.com/r/nixos/nix/ now. The master
branch of the "docker" repository is available as "latest". Branches that match
the regular expression "^[0-9.]+$" are pushed to the tag that corresponds to
their branch name. Other branches are ignored.
The path /root/.nix-profile is a sym-link to /nix/var/nix/profiles/default. The
latter path, however, works for everyone while the former path works only for
root, so we prefer the public path whenever possible.
- Use the latest Nix version 1.11.14.
- Attempts to download the Nix installation tarball from http://nixos.org
redirect to https these days, which wget doesn't support unless OpenSSL is
available.
- Use addgroup and adduser commands to create the Nix build users.
- Link the Nix profile script into /etc/profile.d, where it's run
automatically.
- Dropped installation of bash and tar. Neither tool is essential for running
Nix.
Use the command "docker build -t nix . && docker run -it --rm nix sh -"
to build and run the Nix docker container.
This removes the file nix-mode.el from Nix. The file is now available within the
repository https://github.com/NixOS/nix-mode.

NOTE: all of the above should be fixed within NixOS/nix-mode. If one of those
hasn’t please reopen within NixOS/nix-mode and not within NixOS/nix.
* Dockerfile: add GNU tar native dependency
`builtins.fetchTarball` requires GNU tar to be available in the $PATH in
order to unpack the fetched tarball (there is a FIXME comment for this),
which Alpine does not ship by default (it ships BusyBox tar).
* Dockerfile: add GNU bash native dependency
`nix-shell` defaults to invoking `bash` from the $PATH for the subshell.
In theory this can be overriden with the NIX_BUILD_SHELL environment
variable, but this does not work properly. `nix-shell` generates and
passes a script (`$rcFile`) to be executed by the subshell which uses
bashisms (`source` and `shopt`). Additionally, in interactive mode,
`nix-shell` passes the `--rcfile` argument to the shell, which is
another bashism.
Because `bash` is thus de-facto required, add `bash` as a native package
dependency to make it available for `nix-shell`.
If keywords are matched on the start/end of words then
keywords are also matched if they are surrounded by dashes
or underscores. For example the keyword with is highlighted
in geany-with-vte. When matching on the start/end of symbols
the keyword is only highlighted if it is not part of an other
identifier.
Emacs 24.1 introduced the notion of "basic major modes" and among these
is prog-mode, see section "23.2.5 Basic Major Modes" in the Emacs
manual. The prog-mode basic major mode is recommended as a base for
derived major modes that are intended for editing source code.
- Use define-derived-mode to declare nix-mode
- Use autoloads to ensure nix-mode is usable (and enabled) without needing `require`
- Use set + make-local-variable instead of longer 2-step equivalent
