Eelco Dolstra aac14222f5 nix-profile.sh: Revert to single-user version
Commit 6a214f3e06 copied most of the Nix
shell initialisation code from NixOS to nix-profile.sh; however, that
code assumes a multi-user install and is Linux-specific (e.g. it calls
the "stat" command).  So go back to the simple single-user version.

Fixes #49.

Eelco Dolstra 47ae3ce2ca Put a time-to-live on negative binary cache lookups
Negative lookups are purged from the DB after a day, at most once per
day.  However, for non-"have" lookups (e.g. all except "nix-env
-qas"), negative lookups are ignored after one hour.  This is to
ensure that you don't have to wait a day for an operation like
"nix-env -i" to start using new binaries in the cache.

Should probably make this configurable.

Eelco Dolstra 8fbe96cb31 RemoteStore::connectToDaemon(): Set close-on-exec flag
This ensures that "nix-build --run-env" doesn't keep a connection to
the worker open, preventing it from exiting.

Eelco Dolstra 2923b55f9d Delete paths in a component in topologically sorted order
The outputs of a derivation can refer to each other (even though they
cannot have cycles), so they have to be deleted in the right order.

Eelco Dolstra 6c4ac29917 Disable auto store optimisation for now
I've seen operations like "nix-store --import" take much longer on one
system.  So default to off until I've investigated this a bit further.

Eelco Dolstra e56f71edaf In startBuilder(), only print the new paths we're building 2012-09-13 10:06:24 -04:00
Eelco Dolstra 4fca02077c Handle gc-keep-outputs and gc-keep-derivations both enabled
If the options gc-keep-outputs and gc-keep-derivations are both
enabled, you can get a cycle in the liveness graph.  There was a hack
to handle this, but it didn't work with multiple-output derivations,
causing the garbage collector to fail with errors like ‘error: cannot
delete path `...' because it is in use by `...'’.  The garbage
collector now handles strongly connected components in the liveness
graph as a unit and decides whether to delete all or none of the paths
in an SCC.

Eelco Dolstra 479e9172b3 Build hook: Pass the timeout to the remote builder
Note that this will only work if the client has a very recent Nix
version (post 15e1b2c223), otherwise the
--option flag will just be ignored.

Fixes #50.

Eelco Dolstra 4ba47205c6 Fix test failure on Darwin
Apparently our DBD::SQLite links against /usr/lib/libsqlite3.dylib,
which is an old version that doesn't respect foreign key constraints.
So manifests/cache.sqlite doesn't get updated properly when a manifest
disappears.  We should fix our DBD::SQLite, but in the meantime this
will fix the test.

Eelco Dolstra 8cf672091e Support building a derivation if some outputs are already valid (non-chroot case)

Eelco Dolstra a2785b7391 Support building a derivation if some outputs are already valid
This handles the chroot and build hook cases, which are easy.
Supporting the non-chroot-build case will require more work (hash
rewriting!).

Issue #21.

Eelco Dolstra 295027f533 Include config.h before any other header
"config.h" must be included first, because otherwise the compiler
might not see the right value of _FILE_OFFSET_BITS.  We've had this
before; see 705868a8a9.  In this case,
GCC would compute a different address for ‘settings.useSubstitutes’ in
misc.cc because of the off_t in ‘settings’.

Eelco Dolstra a9e6752bbd Include the output name in the GC root link
Output names are now appended to resulting GC symlinks, e.g. by
nix-build.  For backwards compatibility, if the output is named "out",
nothing is appended.  E.g. doing "nix-build -A foo" on a derivation
that produces outputs "out", "bin" and "dev" will produce symlinks
"./result", "./result-bin" and "./result-dev", respectively.

Eelco Dolstra 56e30e161c In the chroot, make all mounted filesystems private
This is required on systemd, which mounts filesystems as "shared"
subtrees.  Changes to shared trees in a private mount namespace are
propagated to the outside world, which is bad.

Eelco Dolstra 3e89ef597c Optimise concatenating a list to an empty list
More precisely, in concatLists, if all lists except one are empty,
then just return the non-empty list.  This reduces the number of list
element allocations by 32% when evaluating a NixOS system
configuration.
