Daniel Pauls 1e1cd6e7a9 libfetchers: Fix assertion
The filter expects all paths to have a prefix of the raw `actualUrl`, but
`Store::addToStore(...)` provides absolute canonicalized paths.
To fix this create an absolute and canonicalized path from the `actualUrl` and
use it instead.

Fixes #6195.

Eelco Dolstra 318936366d Fix empty 'nix copy' error message
This was caused by SubstitutionGoal not setting the errorMsg field in
its BuildResult. We now get a more descriptive message than in 2.7.0, e.g.

  error: path '/nix/store/13mh...' is required, but there is no substituter that can build it

instead of the misleading (since there was no build)

  error: build of '/nix/store/13mh...' failed

Fixes #6295.

Eelco Dolstra 589f6f267b fetchClosure: Don't allow URL query parameters
Allowing this is a potential security hole, since it allows the user
to specify parameters like 'local-nar-cache'.

Daniel Pauls 1fa0393479 libutil: Reserve memory when en/decoding base64
The size of the output when encoding to and decoding from base64 is
(roughly) known so we can allocate it in advance to prevent
reallocation.

Théophane Hufschmitt 660c19eb49 manual: Add some anchor targets for the nix.conf options
For each `nix.conf` option, add an empty html node with a unique `id`
that can be used as an anchor target. Also make the name of the option
be a link to that target so that it’s easily discoverable.

We can’t rewrite the whole list as an html definition list like it’s
done for the builtins because these options also appear in a man page,
and the manpage renderer (lowdown) can’t render arbitrary html. But the
hack here allows to keep the manpage and have the links in the html
version.

Cole Helbling 56009b2639 libutil: don't save cwd fd, use path instead
Saving the cwd fd didn't actually work well -- prior to this commit, the
following would happen:

    : ~/w/vc/nix ; doas outputs/out/bin/nix --experimental-features 'nix-command flakes' run nixpkgs#coreutils -- --coreutils-prog=pwd
    pwd: couldn't find directory entry in ‘../../../..’ with matching i-node
    : ~/w/vc/nix ; doas outputs/out/bin/nix --experimental-features 'nix-command flakes' develop -c pwd
    pwd: couldn't find directory entry in ‘../../../..’ with matching i-node

Cole Helbling 10b9c1b2b2 libutil: save cwd fd in restoreMountNamespace
This doesn't work very well (maybe I'm misunderstanding the desired
implementation):

    pwd: couldn't find directory entry in ‘../../../..’ with matching i-node

aszlig 435848cef1 libutil: Fix restoring mount namespace
I regularly pass around simple scripts by using nix-shell as the script
interpreter, eg. like this:

    #!/usr/bin/env nix-shell
    #!nix-shell -p dd_rescue coreutils bash -i bash

While this works most of the time, I recently had one occasion where it
would not and the above would result in the following:

    $ sudo ./myscript.sh
    bash: ./myscript.sh: No such file or directory

Note the "sudo" here, because this error only occurs if we're root.

The reason for the latter is because running Nix as root means that we
can directly access the store, which makes sure we use a filesystem
namespace to make the store writable. XXX - REWORD!

So when stracing the process, I stumbled on the following sequence:

    openat(AT_FDCWD, "/proc/self/ns/mnt", O_RDONLY) = 3
    unshare(CLONE_NEWNS)                            = 0
    ... later ...
    getcwd("/the/real/cwd", 4096)                   = 14
    setns(3, CLONE_NEWNS)                           = 0
    getcwd("/", 4096)                               = 2

In the whole strace output there are no calls to chdir() whatsoever, so
I decided to look into the kernel source to see what else could change
directories and found this[1]:

    /* Update the pwd and root */
    set_fs_pwd(fs, &root);
    set_fs_root(fs, &root);

The set_fs_pwd() call is roughly equivalent to a chdir() syscall and
this is called when the setns() syscall is invoked[2].
