Eelco Dolstra 5169a6da98 Make $NIX_PATH parsing more robust 2016-04-14 17:29:08 +02:00
Eelco Dolstra c045630522 Support channel:<channel-name> URIs
For convenience, you can now say

  $ nix-env -f channel:nixos-16.03 -iA hello

instead of

  $ nix-env -f https://nixos.org/channels/nixos-16.03/nixexprs.tar.xz -iA hello

Similarly,

  $ nix-shell -I channel:nixpkgs-unstable -p hello
  $ nix-build channel:nixos-15.09 -A hello

Abstracting over the NixOS/Nixpkgs channels location also allows us to
use a more efficient transport (e.g. Git) in the future.

Eelco Dolstra 363f37d084 Make the search path lazier with non-fatal errors
Thus, -I / $NIX_PATH entries are now downloaded only when they are
needed for evaluation. An error to download an entry is a non-fatal
warning (just like non-existant paths).

This does change the semantics of builtins.nixPath, which now returns
the original, rather than resulting path. E.g., before we had

  [ { path = "/nix/store/hgm3yxf1lrrwa3z14zpqaj5p9vs0qklk-nixexprs.tar.xz"; prefix = "nixpkgs"; } ... ]

but now

  [ { path = "https://nixos.org/channels/nixos-16.03/nixexprs.tar.xz"; prefix = "nixpkgs"; } ... ]

Fixes #792.

Verification is slow. Also, we really shouldn't advise users to nuke

Manifests have been superseded by binary caches for years. This also
gets rid of nix-pull, nix-generate-patches and bsdiff/bspatch.

wmertens 4916d92092 Always verify nix store on install
Just wasted a couple hours chasing shadows because the nix store got
corrupted and there was no indication of that anywhere.

Since an install is one-time only, might as well verify.  Optimization
showed that the copied files aren't read-only; fixed that as well.

Also, use /bin/sh since there's a good chance that this script will be
run on systems without /bin/bash

Eelco Dolstra 05fbc606fc nix verify-paths: Add ‘--sigs-needed <N>’ flag
This specifies the number of distinct signatures required to consider
each path "trusted".

Also renamed ‘--no-sigs’ to ‘--no-trust’ for the flag that disables
verifying whether a path is trusted (since a path can also be trusted
if it has no signatures, but was built locally).

Eelco Dolstra dc82160164 Fix "tar: This does not look like a tar archive" with fetchTarball / -I http://

  imported 595 signatures

Eelco Dolstra 9cee600c88 LocalStore: Keep track of ultimately trusted paths
These are content-addressed paths or outputs of locally performed
builds. They are trusted even if they don't have signatures, so "nix
verify-paths" won't complain about them.

Eelco Dolstra 39a6abc0bc nix verify: Support checking against signatures in other stores
Typical usage is to check local paths using the signatures from a
binary cache:

  $ nix verify-paths -r /run/current-system -s https://cache.nixos.org
  path ‘/nix/store/c1k4zqfb74wba5sn4yflb044gvap0x6k-nixos-system-mandark-16.03.git.fc2d7a5M’ is untrusted
  ...

Eelco Dolstra ab3ce1cc13 Improve SIGINT handling in multi-threaded programs
The flag remembering whether an Interrupted exception was thrown is
now thread-local. Thus, all threads will (eventually) throw
Interrupted. Previously, one thread would throw Interrupted, and then
the other threads wouldn't see that they were supposed to quit.

Eelco Dolstra 4f34c40398 Add "nix verify-store" command
Like "nix-store --verify --check-contents", but with the same
advantages as "nix verify-paths".
2016-03-29 16:37:16 +02:00
Eelco Dolstra 784ee35c80 Add "nix verify-paths" command
Unlike "nix-store --verify-path", this command verifies signatures in
addition to store path contents, is multi-threaded (especially useful
when verifying binary caches), and has a progress indicator.

Example use:

$ nix verify-paths --store https://cache.nixos.org -r $(type -p thunderbird)
...

Eelco Dolstra c7d44bad00 Drop support for daemon socket path >= 108 characters
Doing a chdir() is a bad idea in multi-threaded programs, leading to
failures such as

  error: cannot connect to daemon at ‘/nix/var/nix/daemon-socket/socket’: No such file or directory

Since Linux doesn't have a connectat() syscall like FreeBSD, there is
no way we can support this in a race-free way.
