2014-02-26Only start download-via-ssh if it's enabledEelco Dolstra
2014-02-26Add use-ssh-substituter setting.Shea Levy
It defaults to false and can be overridden by RemoteStore. Untested currently, just quickly put this together
2014-02-19nix-instantiate: Allow --dry-run as a synonym for --readonly-modeEelco Dolstra
--dry-run is more consistent with nix-env and nix-store.
2014-02-19nix-instantiate: Rename --eval-only to --eval, --parse-only to --parseEelco Dolstra
2014-02-19nix-instantiate: Add a flag --expr / -E to read expressions from the command ↵Eelco Dolstra
line This is basically a shortcut for ‘echo 'expr...' | nix-instantiate -’. Also supported by nix-build and nix-shell.
2014-02-18lexer-tab.o and parser-tab.o require each other's headersShea Levy
2014-02-18Slight simplificationEelco Dolstra
2014-02-18Add a flag ‘--check’ to verify build determinismEelco Dolstra
The flag ‘--check’ to ‘nix-store -r’ or ‘nix-build’ will cause Nix to redo the build of a derivation whose output paths are already valid. If the new output differs from the original output, an error is printed. This makes it easier to test if a build is deterministic. (Obviously this cannot catch all sources of non-determinism, but it catches the most common one, namely the current time.) For example: $ nix-build '<nixpkgs>' -A patchelf ... $ nix-build '<nixpkgs>' -A patchelf --check error: derivation `/nix/store/1ipvxsdnbhl1rw6siz6x92s7sc8nwkkb-patchelf-0.6' may not be deterministic: hash mismatch in output `/nix/store/4pc1dmw5xkwmc6q3gdc9i5nbjl4dkjpp-patchelf-0.6.drv' The --check build fails if not all outputs are valid. Thus the first call to nix-build is necessary to ensure that all outputs are valid. The current outputs are left untouched: the new outputs are either put in a chroot or diverted to a different location in the store using hash rewriting.
2014-02-17Make --repair work on DarwinEelco Dolstra
Mac OS X doesn't allow renaming a read-only directory. http://hydra.nixos.org/build/9113895
2014-02-17RefactoringEelco Dolstra
2014-02-17When using a build hook, only copy missing pathsEelco Dolstra
2014-02-17Move some code aroundEelco Dolstra
In particular, do replacing of valid paths during repair later. This prevents us from replacing a valid path after the build fails.
2014-02-17nix-store --gc --max-freed: Support a unit specifierEelco Dolstra
E.g. "--max-freed 10G" means "free ten gigabytes".
2014-02-17Heuristically detect if a build may have failed due to a full diskEelco Dolstra
This will allow Hydra to detect that a build should not be marked as "permanently failed", allowing it to be retried later.

2014-02-08Add download-via-ssh substituterShea Levy
This substituter connects to a remote host, runs nix-store --serve there, and then forwards substituter commands on to the remote host and sends their results to the calling program. The ssh-substituter-hosts option can be specified as a list of hosts to try. This is an initial implementation and, while it works, it has some limitations: * Only the first host is used * There is no caching of query results (all queries are sent to the remote machine) * There is no informative output (such as progress bars) * Some failure modes may cause unhelpful error messages * There is no concept of trusted-ssh-substituter-hosts Signed-off-by: Shea Levy <shea@shealevy.com>

2014-02-08nix-store --serve: Don't loop foreverShea Levy
nix-store --export takes a tmproot, which can only release by exiting. Substituters don't currently work in a way that could take advantage of the looping, anyway. Signed-off-by: Shea Levy <shea@shealevy.com>
2014-02-08Add the nix-store --serve commandShea Levy
This is essentially the substituter API operating on the local store, which will be used by the ssh substituter. It runs in a loop rather than just taking one command so that in the future nix will be able to keep one connection open for multiple instances of the substituter.

2014-02-07nix-instantiate: Add a --no-readonly-mode flagShea Levy
This allows running nix-instantiate --eval-only without performing the evaluation in readonly mode, letting features like import from derivation and automatic substitution of builtins.storePath paths work. Signed-off-by: Shea Levy <shea@shealevy.com>
2014-02-03Fix assertion failure in ‘nix-store --load-db’Eelco Dolstra
Namely: nix-store: derivations.cc:242: nix::Hash nix::hashDerivationModulo(nix::StoreAPI&, nix::Derivation): Assertion `store.isValidPath(i->first)' failed. This happened because of the derivation output correctness check being applied before the references of a derivation are valid.
2014-02-01Give a friendly error message if the DB directory is not writableEelco Dolstra
Previously we would say "error: setting synchronous mode: unable to open database file" which isn't very helpful.
