f2c3fc5191 * Don't show trace information by default (`--show-trace' to enable).
NixOS evaluation errors in particular look intimidating and
  generally aren't very useful.  Ideally the builtins.throw messages
  should be self-contained.

098cb9d233 Add an ftruncate call paired with fallocate to play safe with some FSes (namely, BtrFS fallocate sets file size to allocated size, i.e. multiple of block size) 2009-05-04 08:10:24 +00:00

4e646b0ddb * Fix a few "comparison is always false/true due to limited range of
data type" warnings on 64-bit platforms.  The one in parser.y is
  likely to be a real bug.

3a2bbe7f8a * Simplify communication with the hook a bit (don't use file
descriptors 3/4, just use stdin/stderr).

77d272623f * NAR archives: handle files larger than 2^32 bytes. Previously it
would just silently store only (fileSize % 2^32) bytes.
* Use posix_fallocate if available when unpacking archives.
* Provide a better error message when trying to unpack something that
  isn't a NAR archive.

07cdfb09fb * Open the connection to the daemon lazily (on demand) so that
read-only operations (like nix-env -qa) work properly when the
  daemon isn't running.

9ccdb80de3 * Don't ignore errors from writing to stderr. That way, when
nix-store -r (or some other operation) is started via ssh, it will
  at least have a chance of terminating quickly when the connection is
  killed.  Right now it just runs to completion, because it never
  notices that stderr is no longer connected to anything.  Of course
  it would be better if sshd would just send a SIGHUP, but it doesn't
  (https://bugzilla.mindrot.org/show_bug.cgi?id=396).

Eelco Dolstra
7ab68961e4 * Garbage collector: added an option `--use-atime' to delete paths in
order of ascending last access time.  This is useful in conjunction
  with --max-freed or --max-links to prefer deleting non-recently used
  garbage, which is good (especially in the build farm) since garbage
  may become live again.

  The code could easily be modified to accept other criteria for
  ordering garbage by changing the comparison operator used by the
  priority queue in collectGarbage().

b428adc267 * Strip off the `.nix' suffix from the attribute name for files in
~/.nix-defexpr,  otherwise the attribute cannot be selected with the
  `-A' option.  Useful if you want to stick a Nix expression directly
  in ~/.nix-defexpr.

3c92ea399d * Make nix-env --dry-run print the paths to be substituted correctly
again.  (After the previous substituter mechanism refactoring I
  didn't update the code that obtains the references of substitutable
  paths.)  This required some refactoring: the substituter programs
  are now kept running and receive/respond to info requests via
  stdin/stdout.

329025253d * Use /tmp/nix-build-<drvpath>-<counter> instead of
/tmp/nix-<pid>-<counter> for temporary build directories.  This
  increases purity a bit: many packages store the temporary build path
  in their output, causing (generally unimportant) binary differences.

df303666bc * Use strsignal if available to give better error messages for
builders that fail due to a signal.

633518628f * nix-env -e: support uninstalling by path, so that one can say
$ nix-env -e $(which firefox)

  or

    $ nix-env -e /nix/store/nywzlygrkfcgz7dfmhm5xixlx1l0m60v-pan-0.132

* nix-env -i: if an argument contains a slash anywhere, treat it as a
  path and follow it through symlinks into the Nix store.  This allows
  things like

    $ nix-build -A firefox
    $ nix-env -i ./result

* nix-env -q/-i/-e: don't complain when the `*' selector doesn't match
  anything.  In particular, `nix-env -q \*' doesn't fail anymore on an
  empty profile.

dc6f373842 * Delete the chroot directory automatically.
* Removed some debug messages.
2007-10-27 16:06:38 +00:00
Eelco Dolstra
9397cd30c8 * Support for doing builds in a chroot under Linux. The builder is
executed in a chroot that contains just the Nix store, the temporary
  build directory, and a configurable set of additional directories
  (/dev and /proc by default).  This allows a bit more purity
  enforcement: hidden build-time dependencies on directories such as
  /usr or /nix/var/nix/profiles are no longer possible.  As an added
  benefit, accidental network downloads (cf. NIXPKGS-52) are prevented
  as well (because files such as /etc/resolv.conf are not available in
  the chroot).

  However the usefulness of chroots is diminished by the fact that
  many builders depend on /bin/sh, so you need /bin in the list of
  additional directories.  (And then on non-NixOS you need /lib as
  well...)

055608227f * nix-env: allow ~/.nix-defexpr to be a directory. If it is, then the
Nix expressions in that directory are combined into an attribute set
  {file1 = import file1; file2 = import file2; ...}, i.e. each Nix
  expression is an attribute with the file name as the attribute
  name.  Also recurses into directories.

* nix-env: removed the "--import" (-I) option which set the
  ~/.nix-defexpr symlink.

* nix-channel: don't use "nix-env --import", instead symlink
  ~/.nix-defexpr/channels.  So finally nix-channel --update doesn't
  override any default Nix expressions but combines with them.

  This means that you can have (say) a local Nixpkgs SVN tree and use
  it as a default for nix-env:

  $ ln -s .../path-to-nixpkgs-tree ~/.nix-defexpr/nixpkgs_svn

  and be subscribed to channels (including Nixpkgs) at the same time.
  (If there is any ambiguity, the -A flag can be used to
  disambiguate, e.g. "nix-env -i -A nixpkgs_svn.pan".)

9e975458b4 * Get rid of the substitutes database table (NIX-47). Instead, if we
need any info on substitutable paths, we just call the substituters
  (such as download-using-manifests.pl) directly.  This means that
  it's no longer necessary for nix-pull to register substitutes or for
  nix-channel to clear them, which makes those operations much faster
  (NIX-95).  Also, we don't have to worry about keeping nix-pull
  manifests (in /nix/var/nix/manifests) and the database in sync with
  each other.

  The downside is that there is some overhead in calling an external
  program to get the substitutes info.  For instance, "nix-env -qas"
  takes a bit longer.

  Abolishing the substitutes table also makes the logic in
  local-store.cc simpler, as we don't need to store info for invalid
  paths.  On the downside, you cannot do things like "nix-store -qR"
  on a substitutable but invalid path (but nobody did that anyway).

* Never catch interrupts (the Interrupted exception).

Eelco Dolstra
cbfac2fdcc * Set a terminate() handler to ensure that we leave the BDB
environment cleanly even when an exception is thrown from a
  destructor.  We still crash, but we don't take all other Nix
  processes with us.
2007-05-01 15:16:17 +00:00
Eelco Dolstra
8ab229ddf2 * Terminate build hooks and substitutes with a TERM signal, not a KILL
signal.  This is necessary because those processes may have joined
  the BDB environment, so they have to be given a chance to clean up.

43c4d18c6a * nix-store --import': import an archive created by nix-store
--export' into the Nix store, and optionally check the cryptographic
  signatures against /nix/etc/nix/signing-key.pub.  (TODO: verify
  against a set of public keys.)
2007-02-21 15:45:32 +00:00
Eelco Dolstra
46e0919ced * `nix-store --export --sign': sign the Nix archive using the RSA key
in /nix/etc/nix/signing-key.sec

11158028be * Cleanup. 2007-01-13 14:21:49 +00:00
Eelco Dolstra
a3e6415ba8 * New primop builtins.filterSource, which can be used to filter files
from a source directory.  All files for which a predicate function
  returns true are copied to the store.  Typical example is to leave
  out the .svn directory:

    stdenv.mkDerivation {
      ...
      src = builtins.filterSource
        (path: baseNameOf (toString path) != ".svn")
        ./source-dir;
      # as opposed to
      #   src = ./source-dir;
    }

  This is important because the .svn directory influences the hash in
  a rather unpredictable and variable way.

b438d37558 * In dumpPath(): pass a function object that allows files to be

Eelco Dolstra
29cf434a35 * The determination of the root set should be made by the privileged
process, so forward the operation.
* Spam the user about GC misconfigurations (NIX-71).
* findRoots: skip all roots that are unreadable - the warnings with
  which we spam the user should be enough.

0130ef88ea * Daemon mode (`nix-worker --daemon'). Clients connect to the server
via the Unix domain socket in /nix/var/nix/daemon.socket.  The
  server forks a worker process per connection.
* readString(): use the heap, not the stack.
* Some protocol fixes.

363f40022f * Pid::kill() should be interruptable. 2006-12-03 02:12:26 +00:00

7951c3c546 * Some hackery to propagate the worker's stderr and exceptions to the
client.
2006-12-03 02:08:13 +00:00
Eelco Dolstra
e25fad691a * Move addTempRoot() to the store API, and add another function
syncWithGC() to allow clients to register GC roots without needing
  write access to the global roots directory or the GC lock.
2006-12-02 16:41:36 +00:00

536595b072 * Remove most of the old setuid code.
* Much simpler setuid code for the worker in slave mode.

Eelco Dolstra
9c9cdb06d0 * Remove SwitchToOriginalUser, we're not going to need it anymore. 2006-12-02 14:34:14 +00:00
Eelco Dolstra
0565b5f2b3 * More remote operations.
* Added new operation hasSubstitutes(), which is more efficient than
  querySubstitutes().size() > 0.
2006-11-30 22:43:55 +00:00
Eelco Dolstra
765bdfe542 * When NIX_REMOTE is set to "slave", fork off nix-worker in slave
mode.  Presumably nix-worker would be setuid to the Nix store user.
  The worker performs all operations on the Nix store and database, so
  the caller can be completely unprivileged.

  This is already much more secure than the old setuid scheme, since
  the worker doesn't need to do Nix expression evaluation and so on.
  Most importantly, this means that it doesn't need to access any user
  files, with all resulting security risks; it only performs pure
  store operations.

  Once this works, it is easy to move to a daemon model that forks off
  a worker for connections established through a Unix domain socket.
  That would be even more secure.
2006-11-30 19:54:43 +00:00
Eelco Dolstra
40b3f64b55 * Skeleton of the privileged worker program.
* Some refactoring: put the NAR archive integer/string serialisation
  code in a separate file so it can be reused by the worker protocol
  implementation.

92417600a1 * Example script to set permissions for setuid operation. 2006-11-29 21:58:09 +00:00
Eelco Dolstra
71e867c5f5 * Remove --enable-setuid, --with-nix-user and --with-nix-group.
Rather, setuid support is now always compiled in (at least on
  platforms that have the setresuid system call, e.g., Linux and
  FreeBSD), but it must enabled by chowning/chmodding the Nix
  binaries.

c6a97e3b74 * Doh! Path sizes need to be computed recursively of course.

Eelco Dolstra
8478cd260f * readFile: don't overflow the stack on large files. 2006-10-30 11:56:09 +00:00
Eelco Dolstra
d7efd76394 * Big cleanup of the semantics of paths, strings, contexts, string
concatenation and string coercion.  This was a big mess (see
  e.g. NIX-67).  Contexts are now folded into strings, so that they
  don't cause evaluation errors when they're not expected.  The
  semantics of paths has been clarified (see nixexpr-ast.def).
  toString() and coerceToString() have been merged.

  Semantic change: paths are now copied to the store when they're in a
  concatenation (and in most other situations - that's the
  formalisation of the meaning of a path).  So

    "foo " + ./bla

  evaluates to "foo /nix/store/hash...-bla", not "foo
  /path/to/current-dir/bla".  This prevents accidental impurities, and
  is more consistent with the treatment of derivation outputs, e.g.,
  `"foo " + bla' where `bla' is a derivation.  (Here `bla' would be
  replaced by the output path of `bla'.)

d6f586d0ea * Optional switch "--with-openssl=<PATH>" to use OpenSSL's
implementations of MD5, SHA-1 and SHA-256.  The main benefit is that
  we get assembler-optimised implementations of MD5 and SHA-1 (though
  not SHA-256 (at least on x86), unfortunately).  OpenSSL's SHA-1
