Sandboxes cannot be nested, so if Nix's build runs inside a sandbox,
it cannot use a sandbox itself. I don't see a clean way to detect
whether we're in a sandbox, so use a test-specific hack.

This is mostly for use in the sandbox tests, since if the Nix store is
under /build, then we can't use /build as the build directory.
|
|
This only runs on Linux because it requires a diverted store (which
uses mount/user namespaces).
|

This is to simplify remote build configuration. These environment
variables predate nix.conf.
The build hook now has a sensible default (namely build-remote).
The current load is kept in the Nix state directory now.
|
|
|
|
|
|
This makes all config options self-documenting.
Unknown or unparseable config settings and --option flags now cause a
warning.
|
|
Timeout tests rely on failed build to determine success,
so make sure these derivations (silent in particular)
don't fail regardless of timeout behavior.
|
|
Without this (minor) change, the options set using "--option"
or read from nix.conf were parsed but not used.

The nix-shell fix in 668fef2e4f1c7758e2a55e355b4826014d5b7ba9 revealed
that we had some --pure tests that incorrectly depended on PATH from
config.nix's mkDerivation being overwritten by the caller's PATH.

Fixes #341

build-remote: Implement in C++
|
|
This closes a long-time bug that allowed builds to hang Nix
indefinitely (regardless of timeouts) simply by doing
exec > /dev/null 2>&1; while true; do true; done
Now, on EOF, we just send SIGKILL to the child to make sure it's
really gone.

"i < argc - 1" should be "i < argc".
|
|
nix-shell -A, -p and -i are lightly tested.

This reverts commit 9f3f2e21edb17dbcd674539dff96efb6cceca10c, reversing
changes made to 47f587700d646f5b03a42f2fa57c28875a31efbe.

Commands such as "cp -p" also use fsetxattr() in addition to fchown(),
so we need to make sure these syscalls always return successful as well
in order to avoid nasty "Invalid value" errors.

Right now it only tests whether seccomp correctly forges the return
value of chown, but the long-term goal is to test the full sandboxing
functionality at some point in the future.

Fixed the parsing of multiline strings ending with an even number of
stars, like /** this **/.
Added test cases for comments.

This caused the gc test to fail on Darwin.
|
|
It was failing on some platforms.

The implementation of "partition" in Nixpkgs is O(n^2) (because of the
use of ++), and for some reason was causing stack overflows in
multi-threaded evaluation (not sure why).
This reduces "nix-env -qa --drv-path" runtime by 0.197s and memory
usage by 298 MiB (in non-Boehm mode).
|
|
For example, you can now say:
configureFlags = "--prefix=${placeholder "out"} --includedir=${placeholder "dev"}";
The strings returned by the ‘placeholder’ builtin are replaced at
build time by the actual store paths corresponding to the specified
outputs.
Previously, you had to work around the inability to self-reference by doing stuff like:
preConfigure = ''
configureFlags+=" --prefix $out --includedir=$dev"
'';
or rely on ad-hoc variable interpolation semantics in Autoconf or Make
(e.g. --prefix=\$(out)), which doesn't always work.
|
|
This variable has no reason to exist, given $NIX_STATE_DIR.
|
|
Rarely used, nix copy replaces it.

Also, test HttpBinaryCacheStore in addition to LocalBinaryCacheStore.

This is now done in LocalStore::addToStore(), rather than in the
binary cache substituter (which no longer exists).
