Tuomas Tynkkynen f770b9e6c5 libstore: mmap() returns MAP_FAILED, not NULL on failure 2016-01-05 13:26:35 +01:00
Eelco Dolstra 71a93a5f0e Don't allow sandbox profile except in relaxed mode
This makes Darwin consistent with Linux: Nix expressions can't break
out of the sandbox unless relaxed sandbox mode is enabled.

For the normal sandbox mode this will require fixing #759 however.

Eelco Dolstra 77ad443bd1 ~PathLocks(): Handle exceptions
Otherwise, since the call to write a "d" character to the lock file
can fail with ENOSPC, we can get an unhandled exception resulting in a
call to terminate().

Eelco Dolstra b8258a4475 Fix regression in passAsFile
Caused by 8063fc497a. If tmpDir !=
tmpDirInSandbox (typically when there are multiple concurrent builds
with the same name), the *Path attribute would not point to an
existing file. This caused Nixpkgs' writeTextFile to write an empty
file. In particular this showed up as hanging VM builds (because it
would run an empty run-nixos-vm script and then wait for it to finish
booting).

Eelco Dolstra a9faa7bbce showId: Handle empty attribute names
We should probably disallow these, but until then, we shouldn't barf
with an assertion failure.

Fixes #738.

Eelco Dolstra 8f67325a7c Build sandbox support etc. unconditionally on Linux
Also, use "#if __APPLE__" instead of "#if SANDBOX_ENABLED" to prevent
ambiguity.

Bjørn Forsman 65bd82d42a Clarify error message for hash mismatches (again)
This is arguably nitpicky, but I think this new formulation is even
clearer. My thinking is that it's easier to comprehend when the
calculated hash value is displayed close to the output path. (I think it
is somewhat similar to eliminating double negatives in logic
statements.)

The formulation is inspired / copied from the OpenEmbedded build tool,
bitbake.

Ludovic Courtès d1e3bf01bc daemon: Add 'buildMode' parameter to 'buildPaths' RPC 2015-12-02 18:14:49 +01:00
Eelco Dolstra 8063fc497a Use deterministic $TMPDIR in sandbox
Rather than using $<host-TMPDIR>/nix-build-<drvname>-<number>, the
temporary directory is now always /tmp/nix-build-<drvname>-0. This
improves bitwise-exact reproducibility for builds that store $TMPDIR
in their build output. (Of course, those should still be fixed...)

Pascal Wittmann 4921223160 Print license information on '--xml --meta'
The nixpkgs manual prescribes the use of values from stdenv.lib.licenses
for the meta.license attribute. Those values are attribute sets and
currently skipped when running nix-env with '--xml --meta'. This has the
consequence that also nixpkgs-lint will report missing licenses.

With this commit nix-env with '--xml --meta' will print all attributes
of an attribute set that are of type tString. For example the output for
the package nixpkgs.hello is

    <meta name="license" type="strings">
      <string type="url" value="http://spdx.org/licenses/GPL-3.0+" />
      <string type="shortName" value="gpl3Plus" />
      <string type="fullName" value="GNU General Public License v3.0 or later" />
      <string type="spdxId" value="GPL-3.0+" />
    </meta>

This commit fixes nixpkgs-lint, too.

Peter Simons 6ad10591ce src/libstore/build.cc: clarify error message for hash mismatches
Nix reports a hash mismatch saying:

  output path ‘foo’ should have sha256 hash ‘abc’, instead has ‘xyz’

That message is slightly ambiguous and some people read that statement
to mean the exact opposite of what it is supposed to mean. After this
patch, the message will be:

  Nix expects output path ‘foo’ to have sha256 hash ‘abc’, instead it has ‘xyz’

Vladimír Čunát b39622a487 rename chroot to sandbox (fixes #656, close #682)
- rename options but leav old names as lower-priority aliases,
  also "-dirs" -> "-paths" to get closer to the meaning
- update docs to reflect the new names (old aliases are not documented),
  including a new file with release notes
- tests need an update after corresponding changes to nixpkgs
- __noChroot is left as it is (after discussion on the PR)

Eelco Dolstra 8fdd156a65 Add option to verify build determinism
Passing "--option build-repeat <N>" will cause every build to be
repeated N times. If the build output differs between any round, the
build is rejected, and the output paths are not registered as
valid. This is primarily useful to verify build determinism. (We
already had a --check option to repeat a previously succeeded
build. However, with --check, non-deterministic builds are registered
in the DB. Preventing that is useful for Hydra to ensure that
non-deterministic builds don't end up getting published at all.)

Eelco Dolstra 96c2ebf004 Revert "Allow using /bin and /usr/bin as impure prefixes on non-darwin by default"
This reverts commit 79ca503332. Ouch,
never noticed this. We definitely don't want to allow builds to have
arbitrary access to /bin and /usr/bin, because then they can (for
instance) bring in a bunch of setuid programs. Also, we shouldn't be
encouraging the use of impurities in the default configuration.

Eelco Dolstra 4384bbd2e1 optimizePath(): Detect some .links corruption
If automatic store optimisation is enabled, and a hard-linked file in
the store gets corrupted, then the corresponding .links entry will
also be corrupted. In that case, trying to repair with --repair or
--repair-path won't work, because the new "good" file will be replaced
by a hard link to the corrupted file. We can catch most of these cases
by doing a sanity-check on the file sizes.

Fixes #679.

Note: on x86_64, SHA-512 is considerably faster than SHA-256 (198 MB/s
versus 131 MB/s).

Eelco Dolstra dae5dc7ade <nix/fetchurl.nix>: Support downloading and unpacking NARs
This removes the need to have multiple downloads in the stdenv
bootstrap process (like a separate busybox binary for Linux, or
curl/mkdir/sh/bzip2 for Darwin). Now all those files can be combined
into a single NAR.
