This function was used in only one place, where it could easily be
replaced by readDerivation() since it's not
performance-critical. (This function appears to have been modelled
after queryDerivationOutputs(), which exists only to make the garbage
collector faster.)
This fixes an issue where lockfile generation was not idempotent:
after updating a lockfile, a "follows" node would end up pointing to a
new copy of the node, rather than to the original node.
This combines the *.o into a big .o producing one translation unit.
This preserve our unused static initializers, as specified in the C++
standard:
If no variable or function is odr-used from a given translation
unit, the non-local variables defined in that translation unit may
never be initialized (this models the behavior of an on-demand
dynamic library).
Note that this is very similar to how the --whole-archive flag works.
One advantage of this is that users of the final .a library don’t have
to worry about specifying --whole-archive, or that we have unused
static initializers at all!
fetchTarball, fetchTree, and fetchGit all have *optional* hash attrs.
This means that we need to be careful with what we allow to avoid
accidentally making these defaults. When ‘hash = ""’ we assume the
empty hash is wanted.

This allows hash="" so that it can be used for debugging purposes. For
instance, this gives you an error message like:
warning: found empty hash, assuming you wanted 'sha256:0000000000000000000000000000000000000000000000000000'

Needed so that we can include it as a logger in loggers.cc without
adding a dependency on nix
This also requires moving names.hh to libutil to prevent a circular
dependency between libmain and libexpr
The `remote-store` test loads the `user-env` one to test nix-env when
using the daemon, but actually does it incorrectly because every test
starts (in `common.sh`) by resetting the value of `NIX_REMOTE`, meaning
that the `user-env` test will never use the daemon.
Fix this by setting `NIX_REMOTE_` before sourcing `user-env.sh` in the
`remote-store` test, so that `NIX_REMOTE` is correctly set inside the
test
Make the printing of the build logs systematically go through the
logger, and replicate the behavior of `no-build-output` by having two
different loggers (one that prints the build logs and one that doesn't)
Add a new `--log-format` cli argument to change the format of the logs.
The possible values are
- raw (the default one for old-style commands)
- bar (the default one for new-style commands)
- bar-with-logs (equivalent to `--print-build-logs`)
- internal-json (the internal machine-readable json format)
