John Ericson 3a7b330b64 "Downstream placeholders" should not be store paths
Insead they should be opaque `/<hash>` like the placeholders we already
have.

Chuck ed026f7206 Don't try to parse signature check as commit timestamp
When the log.showSignature git setting is enabled, the output of
"git log" contains signature verification information in addition to the
timestamp GitInputScheme::fetch wants:

  $ git log -1 --format=%ct
  gpg: Signature made Sat 07 Sep 2019 02:02:03 PM PDT
  gpg:                using RSA key 0123456789ABCDEF0123456789ABCDEF01234567
  gpg:                issuer "user@example.com"
  gpg: Good signature from "User <user@example.com>" [ultimate] 1567890123
  1567890123

For folks that had log.showSignature set, this caused all nix operations
on flakes to fail:

  $ nix build
  error: stoull

John Ericson e1308b1211 Define LegacySSHStore::buildPaths using cmdBuildPaths
Evidentally this was never implemented because Nix switched to using
`buildDerivation` exclusively before `build-remote.pl` was rewritten.

The `nix-copy-ssh` test (already) tests this.

John Ericson 5ccd94501d Allow trustless building of CA derivations
Include a long comment explaining the policy. Perhaps this can be moved
to the manual at some point in the future.

Also bump the daemon protocol minor version, so clients can tell whether
`wopBuildDerivation` supports trustless CA derivation building. I hope
to take advantage of this in a follow-up PR to support trustless remote
building with the minimal sending of derivation closures.

John Ericson 4720853129 Make system-features a store setting
This seems more correct. It also means one can specify the features a
store should support with --store and remote-store=..., which is useful.
I use this to clean up the build remotes test.
2020-08-12 18:13:00 +00:00
John Ericson 8d4162ff9e Separate auth and logic for the daemon
Before, processConnection wanted to know a user name and user id, and
`nix-daemon --stdio`, when it isn't proxying to an underlying daemon,
would just assume "root" and 0. But `nix-daemon --stdio` (no proxying)
shouldn't make guesses about who holds the other end of its standard
streams.

Now processConnection takes an "auth hook", so `nix-daemon` can provide
the appropriate policy and daemon.cc doesn't need to know or care what
it is.

Maximilian Bosch 5f8ae16c8b
Always reset ANSI colors in progress-bar line
When having a message like `waiting for a machine to build X` and
building with `nix build -L`, the log-prefix is always colored yellow[1]
on a small terminal-width as everything (including the ANSI color-reset) is
stripped away.

To work around that problem, this patch explicitly adds an `ANSI_NORMAL`
to the end of the line.

Eelco Dolstra 3c75ddc16b nix build (and others): Force re-evaluation of cached errors
Fixes #3872.

This is a bit hacky. Ideally we would automatically re-evaluate the
failed attribute iff we need to print the error message (so in
commands like 'nix search' we wouldn't re-evaluate because we're
suppressing errors).

Matthew Bauer 641c950701 Add hashed-mirrors back
Some users have their own hashed-mirrors setup, that is used to mirror
things in addition to what’s available on tarballs.nixos.org. Although
this should be feasable to do with a Binary Cache, it’s not always
easy, since you have to remember what "name" each of the tarballs has.
Continuing to support hashed-mirrors is cheap, so it’s best to leave
support in Nix. Note that NIX_HASHED_MIRRORS is also supported in
Nixpkgs through fetchurl.nix.

Note that this excludes tarballs.nixos.org from the default, as in
\#3689. All of these are available on cache.nixos.org.

nix/build: add --rebuild option
Occasionally, `nix-build --check` is fairly helpful and I'd like to be
able to use this feature for flakes that need to be built with `nix
build` as well.

Matthew Bauer 2f4250a416 Add "export" to Nix
This adds a ‘nix export’ command which hooks into nix-bundle. It can
be used in a similar way as nix-bundle, with the benefit of hooking
into the new “app” functionality. For instance,

$ nix export nixpkgs#jq
$ ./jq --help
jq - commandline JSON processor [version 1.6]
...
$ scp jq machine-without-nix:
$ ssh machine-without-nix ./jq
jq - commandline JSON processor [version 1.6]
...

Note that nix-bundle currently requires Linux to run. Other exporters
might not have that requirement.

“exporters” are meant to be reusable, so that, other repos can
implement their own bundling.

Matthew Bauer fa8515d7ec Set regex_constants::match_continuous for quicker search
match_continuous limits the search to the current start position,
instead of searching the entire file.

On libc++, this improves performance dramatically:

Eelco Dolstra 4c0077a07d Fix RemoteStore::addToStore() latency
Since 6185d25e52, this was very
latency-bound since it required a round-trip for every 32 KiB. So for
example copying a 514 MiB closure over a virtual ethernet device with
a articial delay of just 1 ms took 343s. Now it takes 2.7s.

Fixes #3372.

Restore backwards-compat for current builtins.fetchGit
If a repo is dirty, it used to return a `rev` object with an "empty"
sha1 (0000000000000000000000000000000000000000). Please note that this
only applies for `builtins.fetchGit` and *not* for `builtins.fetchTree{
type = "git"; }`.
