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
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.
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.
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.
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.
Thanks @regnat for catching one of them. The other follows for many of
the same reasons. I'm find fixing others on a need-to-fix basis,
provided their are no regressions.
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.
