Eelco Dolstra 656390062a nix-build --run-env: Source $stdenv/setup in the interactive shell
This ensures that not just environment variables are set, but also
shell functions such as unpackPhase, configurePhase and so on.

Eelco Dolstra 1917d750a0 copy-from-other-stores.pl: Report downloaded size as 0 2013-07-01 13:29:59 +02:00
Eelco Dolstra 7ccd946407 Don't set $preferLocalBuild and $requiredSystemFeatures in builders
With C++ std::map, doing a comparison like ‘map["foo"] == ...’ has the
side-effect of adding a mapping from "foo" to the empty string if
"foo" doesn't exist in the map.  So we ended up setting some
environment variables by accident.

Eelco Dolstra 5558652709 Don't substitute derivations that have preferLocalBuild set
In particular this means that "trivial" derivations such as writeText
are not substituted, reducing the number of GET requests to the binary
cache by about 200 on a typical NixOS configuration.

Eelco Dolstra 1906cce6fc Increase SQLite's auto-checkpoint interval
Common operations like instantiating a NixOS system config no longer
fitted in 8192 pages, leading to more fsyncs.  So increase this limit.

Eelco Dolstra 9b11165aec Disable the copy-from-other-stores substituter
This substituter basically cannot work reliably since we switched to
SQLite, since SQLite databases may need write access to open them even
just for reading (and in WAL mode they always do).
2013-06-20 12:01:33 +02:00
Eelco Dolstra 22144afa8d Don't keep "disabled" substituters running
For instance, it's pointless to keep copy-from-other-stores running if
there are no other stores, or download-using-manifests if there are no
manifests.  This also speeds things up because we don't send queries
to those substituters.

Eelco Dolstra cd49ee0897 Fix a security bug in hash rewriting
Before calling dumpPath(), we have to make sure the files are owned by
the build user.  Otherwise, the build could contain a hard link to
(say) /etc/shadow, which would then be read by the daemon and
rewritten as a world-readable file.

This only affects systems that don't have hard link restrictions
enabled.

Eelco Dolstra 1e2c7c04b1 Fix assertion failure in canonicalisePathMetaData() after hash rewriting
The assertion in canonicalisePathMetaData() failed because the
ownership of the path already changed due to the hash rewriting.  The
solution is not to check the ownership of rewritten paths.

Issue #122.

Eelco Dolstra f9ff67e948 In repair mode, update the hash of rebuilt paths
Otherwise subsequent invocations of "--repair" will keep rebuilding
the path.  This only happens if the path content differs between
builds (e.g. due to timestamps).

Eelco Dolstra 24a356bf71 Replace $NIX_DEBUG_SUBST with an option ‘debug-subst’
Thus passing ‘--option debug-subst 1’ allows daemon users to turn on
debug info and see what the substituter is doing.

Eelco Dolstra 24e063efdc download-from-binary-cache.pl: Show if we're waiting for a URL
Previously, if a binary cache is hanging/unreachable/slow,
download-from-binary-cache.pl would also hang without any indication
to the user.  Now, if fetching a URL takes more than 5 seconds, it
will print a message to that effect.

Eelco Dolstra ff08306746 download-from-binary-cache.pl: Treat a 403 error as a 404
Amazon S3 returns HTTP status code 403 if a file doesn't exist and the
user has no permission to list the contents of the bucket.  So treat
it as 404 (meaning it's cached in the NARExistence table).

Eelco Dolstra bc2e43f3c8 build-remote.pl: Remove meaningless signing when importing the output paths
The "$UID != 0" makes no sense: if the local side has write access to
the Nix store (which is always the case) then it doesn't matter if
we're root - we can import unsigned paths either way.

Eelco Dolstra 18a48d80a0 Show function names in error messages
Functions in Nix are anonymous, but if they're assigned to a
variable/attribute, we can use the variable/attribute name in error
messages, e.g.

while evaluating `concatMapStrings' at `/nix/var/nix/profiles/per-user/root/channels/nixos/nixpkgs/pkgs/lib/strings.nix:18:25':

Eelco Dolstra be0b9dda31 build-remote.pl: Pass /dev/null as SSH's stdin
Otherwise it will set the parent's stdin to non-blocking mode, causing
the subsequent read of the set of inputs/outputs to fail randomly.
That's insane.

Eelco Dolstra 78206f06ec build-remote.pl: Allow a machine to refuse a build
Before selecting a machine, build-remote.pl will try to run the
command "nix-builds-inhibited" on the machine.  If this command exists
and returns a 0 exit code, then the machine won't be used.  It's up to
the user to provide this command, but it would typically be a script
that checks whether there is enough disk space and whether the load is
not too high.

Eelco Dolstra 2ee9da9e22 In trace messages, don't print the output path
This doesn't work if there is no output named "out".  Hydra didn't use
it anyway.

Eelco Dolstra 69b8f9980f build-remote.pl: Enforce timeouts locally
Don't pass --timeout / --max-silent-time to the remote builder.
Instead, let the local Nix process terminate the build if it exceeds a
timeout.  The remote builder will be killed as a side-effect.  This
gives better error reporting (since the timeout message from the
remote side wasn't properly propagated) and handles non-Nix problems
like SSH hangs.
