Rewrite StorePath class in C++
|
|
Add another missing #include
|
|
|
|
|
|
On nix-env -qa -f '<nixpkgs>', this reduces maximum RSS by 20970 KiB
and runtime by 0.8%. This is mostly because we're not parsing the hash
part as a hash anymore (just validating that it consists of base-32
characters).
Also, replace storePathToHash() by StorePath::hashPart().

|
Fixes #3618.

E.g. instead of
error: --- BuildError ----------------------------------------------- nix
builder for '/nix/store/03nk0a3n8h2948k4lqfgnnmym7knkcma-foo.drv' failed with exit code 1
error: --- Error ---------------------------------------------------- nix
build of '/nix/store/03nk0a3n8h2948k4lqfgnnmym7knkcma-foo.drv' failed
we now get
error: --- Error ---------------------------------------------------- nix
builder for '/nix/store/03nk0a3n8h2948k4lqfgnnmym7knkcma-foo.drv' failed with exit code 1

These are now shown in the progress bar.
Closes #3577.
|
|
|
|
|
|
This means that 'throw Error({ ... ErrorInfo ... })' now works.

Use `std::string_view` in a few more places

Allow empty hash in derivations
|
|
|
|
This replaces the copy&paste with a helper function in hash.hh.
|
|
|
|
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.)
|
|
Add tests for pool.hh
|
|
|
|
Add an option to print the logs in a machine-readable format

libutils/hash: remove default encoding
|
|
Actually test nix-env with a remote store

|
Prelink static libraries into an object file
|
|
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!

WSL1 doesn’t support i686-linux emulation, see https://github.com/microsoft/wsl/issues/2468

|
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.

follow up of https://github.com/NixOS/nix/pull/3544
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'
hash mismatch in fixed-output derivation '/nix/store/asx6qw1r1xk6iak6y6jph4n58h4hdmbm-nix':
wanted: sha256:0000000000000000000000000000000000000000000000000000
got: sha256:0fpfhipl9v1mfzw2ffmxiyyzqwlkvww22bh9wcy4qrfslb4jm429

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)
