2aac7cd021 * Another case of lock file permissions being too liberal. 2011-12-21 19:17:45 +00:00
Eelco Dolstra
4d728bc3e6 * Security: make sure the lock files used by build-remote.pl are not 
readable to other users.  Otherwise, any user can open the lock file
  for reading and lock it, thus DoSing the remote build mechanism.

Eelco Dolstra
69d6f0936a * Use a lock to ensure that only one build-remote instance can copy a 
closure to a given machine at the same time.  This prevents the case
  where multiple instances try to copy the same missing store path to
  the target machine, which is very wasteful.

5679041132 * The ‘foo.drvPath’ feature was already broken in read-only mode. 
Since it's rarely used and fixing it is too much work right now,
  just document it.

f3c88f297d Detect and reject mutually-referential outputs 
There is probably a more efficient way to do this.

b19a0f63db * Simplify the context handling logic. 2011-12-21 15:33:30 +00:00
Eelco Dolstra
4be5a2c096 * Add a test for unsafeDiscardOutputDependency. Not really related to 
multiple outputs, but good to have anyway.
 2011-12-21 14:42:06 +00:00
Eelco Dolstra
179409b911 * Add a test for referring to another derivation's ‘drvPath’. This 
currently fails in read-only mode.

3877619888 * Add some accidentally committed files. 2011-12-21 11:47:52 +00:00

edd9359beb * Doing a GC after building a derivation with cyclic outputs currently 
segfaults.
 2011-12-20 17:10:39 +00:00
Eelco Dolstra
1f3b0ede7d * Add a (currently failing) test that checks whether mutually 
recursive outputs are properly rejected.
* Add a (also failing) test for "nix-build -A <output-name>".

46e42c92c1 * Refactor a bit so that more tests can be added. 2011-12-20 17:01:02 +00:00

b5363810bb * Fix the build. 2011-12-20 16:37:01 +00:00

194d21f9f6 * Sync with the trunk. 2011-12-16 23:33:01 +00:00
Eelco Dolstra
273b288a7e * importPath() -> importPaths(). Because of buffering of the input 
stream it's now necessary for the daemon to process the entire
  sequence of exported paths, rather than letting the client do it.

8d3dfa2c17 * Avoid expensive conversions from char arrays to STL strings. 2011-12-16 21:29:46 +00:00
Eelco Dolstra
e0bd307802 * Make the import operation through the daemon much more efficient 
(way fewer roundtrips) by allowing the client to send data in bigger
  chunks.
* Some refactoring.

78598d06f0 * Clean up exception handling. 2011-12-16 15:45:42 +00:00
Eelco Dolstra
5a1b9ed0aa * Refactoring: move sink/source buffering into separate classes. 
* Buffer the HashSink.  This speeds up hashing a bit because it
  prevents lots of calls to the hash update functions (e.g. nix-hash
  went from 9.3s to 8.7s of user time on the closure of my
  /var/run/current-system).

a67b8ae224 * Typo. 2011-12-15 14:04:35 +00:00
Eelco Dolstra
a3e0656cbb * Buffer reads in FdSource. Together with write buffering, this 
significantly cuts down the number of syscalls (e.g., for "nix-store
  -qR /var/run/current-system" via the daemon, it reduced the number
  of syscalls in the client from 29134 to 4766 and in the daemon from
  44266 to 20666).
 2011-12-15 12:32:08 +00:00
Eelco Dolstra
3a48282b06 * Buffer writes in FdSink. This significantly reduces the number of 
system calls / context switches when dumping a NAR and in the worker
  protocol.

Eelco Dolstra
893cac1402 * Remove the terminate handler, which was only really needed because 
of Berkeley DB (see r8632).
 2011-12-14 22:41:10 +00:00
Eelco Dolstra
23bf700196 * Oops, the daemon test wasn't actually using the daemon. 2011-12-14 22:31:31 +00:00
Eelco Dolstra
c8c0380744 * Remove unnecessary quotes. showPaths() already adds quotes. 2011-12-05 21:04:20 +00:00
Eelco Dolstra
000160f5b9 * In ‘nix-store --verify --check-contents’, repair missing hashes 
rather than complain about them.

3964d95abf * nix-prefetch-url: rewritten in Perl. 2011-12-02 12:09:50 +00:00
Eelco Dolstra
92d6a5ed73 * Add some more functions to the Perl bindings. 2011-12-02 12:09:24 +00:00
Eelco Dolstra
49f59dceca * Move parseHash16or32 into libutil, and use in nix-hash. 2011-12-02 11:47:06 +00:00
Eelco Dolstra
b12b21825c * Allow '<nixexpr>' syntax to be used in nix-instantiate, nix-build 
and nix-env, e.g.,

  $ nix-env -f '<nixpkgs>' -i patchelf

  or

  $ nix-build '<nixos/tests>' -A login.test

23c38a04cc * Slight improvement. 2011-12-01 13:51:05 +00:00
Eelco Dolstra
24f863d86b * When doing "nix-store --add-fixed" without "--recursive" via the Nix 
daemon (which is an error), print a nicer error message than
  "Connection reset by peer" or "broken pipe".
* In the daemon, log errors that occur during request parameter
  processing.

b1eb8f4249 * Get rid of some superfluous error messages if a substituter fails. 
* Say "fetch" instead of "substitute".
 2011-11-29 13:00:41 +00:00
Eelco Dolstra
216440b3ff * For consistency with "nix-store -q --hash", produce hashes in 
base-32.  (This affects Hydra manifests.)

d5ac78e0d6 * Add bzip2 and xz support to nix-copy-closure. 2011-11-23 15:29:58 +00:00
Eelco Dolstra
5bbd693cae * Add an API function exportPaths() that provides the functionality of 
‘nix-store --export’.
* Add a Perl module that provides the functionality of
  ‘nix-copy-closure --to’.  This is used by build-remote.pl so it no
  longer needs to start a separate nix-copy-closure process.  Also, it
  uses the Perl API to do the export, so it doesn't need to start a
  separate nix-store process either.  As a result, nix-copy-closure
  and build-remote.pl should no longer fail on very large closures due
  to an "Argument list too long" error.  (Note that having very many
  dependencies in a single derivation can still fail because the
  environment can become too large.  Can't be helped though.)

ab20af3e6f * build-remote.pl: drop a hard-coded reference to /nix/etc/nix. 2011-11-23 12:21:35 +00:00
Eelco Dolstra
993fa94fb4 * Move initialisation of variables like nixConfDir from libmain to 
libstore so that the Perl bindings can use it as well.  It's vital
  that the Perl bindings use the configuration file, because otherwise
  nix-copy-closure will fail with a ‘database locked’ message if the
  value of ‘use-sqlite-wal’ is changed from the default.
