Shea Levy e3128014db Remove scripts/show-duplication.pl
Was added in 2006 to "measure the cost of the Nix approach".

Given that it uses /usr/bin/perl, I think this is safe to remove.

Aneesh Agrawal c8608c488c Dockerfile: Add alpine dependencies (#1011)
* 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`.

Alexey Shmalko eef754813f Set $MANPATH (#1005)
Currently, man has issues finding man pages for Nix-installed
application (also, `nix-env --help` doesn't work). The issue is caused
by custom `$MANPATH` set by my system. That makes man use it instead of
searching in default location.

Either of next lines workaround the issue:
```sh
unset MANPATH

export MANPATH=$HOME/.nix-profile/share/man:$MANPATH
```

This patch adds the later line to the `nix-profile.sh` if user has
`MANPATH` set. (Not clearing `MANPATH` as that would be disrespect of
user's preferences.)

As a side-effect, host's man might find man pages installed by Nix.

Eelco Dolstra d57981bac4 Store::queryMissing(): Use a thread pool
For one particular NixOS configuration, this cut the runtime of
"nix-store -r --dry-run" from 6m51s to 3.4s. It also fixes a bug in
the size calculation that was causing certain paths to be counted
twice, e.g. before:

  these paths will be fetched (1249.98 MiB download, 2995.74 MiB unpacked):

and after:

  these paths will be fetched (1219.56 MiB download, 2862.17 MiB unpacked):

Matthias Beyer 2ec9d2fb02 NIX_REMOTE_SYSTEMS path must be absolute (#957)
Once upon a time, I wrote my bachelors thesis about functional
deployment mechanisms.

I had to evaluate several szenarios where package management and
deployment were relevant. One szenario was to do distributed builds
over several machines.

I told myself: Weee, nix can do this! And with nix, this is actually
save, as you do not have side effects when building!

So I started. I use a cloud to set up four virtual machines where I
wanted to do the build. A fifth machine was used as master to distribute
the builds. All was good.

I created the necessary SSH keys, made sure every machine was reachable
by the master and configured the build in my remotes.conf.

When I started to try to build weechat from source, the build failed. It
failed, telling me

    error: unable to start any build; either increase ‘--max-jobs’ or enable distributed builds

And I started to dig around. I digged long and good. But I wasn't able
to find the issue.

I double and triple checked my environment variables, my settings, the
SSH key and everything.

I reached out to fellow Nixers by asking on the nixos IRC channel. And I
got help. But we weren't able to find the issue, either.

So I became frustrated. I re-did all the environment variables.

And suddenly,... it worked! What did I change? Well... I made the
environment variables which contained pathes contain absolute pathes
rather than relatives.

And because I like to share my knowledge, this should be put into the
documentation, so others do not bang their heads against the wall
because something is not documented somewhere.

aszlig 72fb2ccfa1
Don't hardcode docbook XSL namespace URL
Docbook XSL got updated to version 1.79.1 in NixOS/nixpkgs@fb893a8 and
we're still referring to the hardcoded previous version.

So instead of just updating this to 1.79.1 we're going to use "current"
in the hope that this won't happen again.

I have tested this by building the manual under Nix(OS) but I haven't
tested this in a non-Nix environment, so I'm not sure whether this could
have implications.

Timothy Allen 3a535abbc7 nix.spec.in: Create /nix/store at install time.
Since we now chmod /nix/store at install time, we don't need to do it in the
post install script. We still chgrp in the post-install, because the nixbld
group doesn't exist at install time.

Timothy Allen f32c6ed873 nix.spec.in: Build from the .tar.xz file.
The Nix download page only mentions the .xz source tarball, so that's what
people are likely to have available. This means that somebody who downloads a
Nix source tarball can turn it directly into an RPM with `rpmbuild -ta
nix-*.tar.xz`.

Timothy Allen 85ec6a6a44 nix.spec.in: Use the default build group name.
Nix expects build users to be in the "nixbld" group. You can change that in the
config file, but `nix.spec` does not ship with a config file, so we should
use the defaults.

Eelco Dolstra c68e5913c7 Run builds in a user namespace
This way, all builds appear to have a uid/gid of 0 inside the
chroot. In the future, this may allow using programs like
systemd-nspawn inside builds, but that will require assigning a larger
UID/GID map to the build.

Issue #625.

Eelco Dolstra 5e51ffb1c2 Support sandbox builds by non-root users
This allows an unprivileged user to perform builds on a diverted store
(i.e. where the physical store location differs from the logical
location).

Example:

  $ NIX_LOG_DIR=/tmp/log NIX_REMOTE="local?real=/tmp/store&state=/tmp/var" nix-build -E \
    'with import <nixpkgs> {}; runCommand "foo" { buildInputs = [procps nettools]; } "id; ps; ifconfig; echo $out > $out"'

will do a build in the Nix store physically in /tmp/store but
logically in /nix/store (and thus using substituters for the latter).
