aac5fcfbb5 Re-add drvPath' and outPath' attributes to <derivation> XML nodes.
This fixes a regression introduced in r20882 ("Add source location
information to the XML output.").

* src/libexpr/expr-to-xml.cc (nix::printTermAsXML): Dereference the
  attribute RHS from "drvPath" and "outPath".

f3dc7ab877 * Keep more statistics about stack space usage.
* Reduce stack space usage.

b7b3dd55f9 * Remove a lot of dead code. 2010-04-08 11:41:19 +00:00
Eelco Dolstra
7e048eddf5 * Fix blackholing. If evaluation fails due to an assertion failure,
then the blackhole has to be removed to ensure that repeated
  evaluation of the same value gives an assertion failure again rather
  than an "infinite recursion" error.

af2a372bb0 * Update autoCallFunction() and findAlongAttrPath(). 2010-04-07 15:47:06 +00:00

9a64454faa * expr-to-xml -> value-to-xml. 2010-04-07 13:59:45 +00:00
Eelco Dolstra
fc92244ba8 * Implemented the primops necessary for generating the NixOS manual. 2010-04-07 13:55:46 +00:00
Eelco Dolstra
a353aef0b1 * In eval(), don't use the target value `v' as a temporary.
Overwriting `v' breaks when the expression evaluation to an
  assertion failure or throw.
2010-04-06 14:15:29 +00:00

a5ece7d016 * Removed the `~' operator. 2010-04-01 16:59:07 +00:00
Eelco Dolstra
c172274e17 * Quick hack to make coerceToString work more or less correctly on
nested lists.  `nix-instantiate' can now evaluate the NixOS system
  derivation attribute correctly (in 2.1s on my laptop vs. 6.2s for
  the trunk).

7b851915bf * Improve sharing. 2010-04-01 12:04:57 +00:00
Eelco Dolstra
95cc417d76 * Functions are incomparable. 2010-04-01 10:55:36 +00:00
Eelco Dolstra
71f026292b * Make `derivation' lazy again for performance. It also turns out
that there are some places in Nixpkgs (php_configurable /
  composableDerivation, it seems) that call `derivation' with
  incorrect arguments (namely, the `name' attribute missing) but get
  away with it because of laziness.
2010-04-01 09:55:57 +00:00
Eelco Dolstra
dc31305b38 * Fixed the trace primop and path comparison.
* Removed exprToString and stringToExpr because there is no ATerm
  representation to work on anymore (and exposing the internals of the
  evaluator like this is not a good idea anyway).
2010-03-31 20:09:20 +00:00
Eelco Dolstra
979f163615 * Handle string contexts. `nix-instantiate' can now correctly compute
the `firefoxWrapper' attribute in Nixpkgs, and it's about 3 times
  faster than the trunk :-)

expressions.

09381cccff Make source location info in the XML output optional.
* src/libexpr/expr-to-xml.cc (nix::showAttrs): Add `location'
  parameter.  Provide location XML attributes when it's true.  Update
  callers.
  (nix::printTermAsXML): Likewise.

* src/libexpr/expr-to-xml.hh (nix::printTermAsXML): Update prototype;
  have `location' default to `false'.

* src/nix-instantiate/nix-instantiate.cc (printResult, processExpr): Add
  `location' parameter; update callers.
  (run): Add support for `--no-location'.

* src/nix-instantiate/help.txt: Update accordingly.

* tests/lang.sh: Invoke `nix-instantiate' with `--no-location' for the
  XML tests.

* tests/lang/eval-okay-toxml.exp, tests/lang/eval-okay-to-xml.nix: New
  files.

Ludovic Courtès
471419d1fa Add source location information to the XML output.
* src/libexpr/expr-to-xml.cc (nix::showAttrs): Dereference the attribute
  RHS.  Add "path", "line", and "column" XML attributes to the node when
  source location information is available.
  (nix::printTermAsXML): Likewise for functions.
2010-03-31 08:29:05 +00:00

eb07a4f1ee Escape `>' signs in the XML output.
* src/libutil/xml-writer.cc (nix::XMLWriter::writeAttrs): Escape `>'.

45d822f29c * Primops (not yet finished). 2010-03-26 15:45:53 +00:00
Eelco Dolstra
cad8726b2c * Implemented the ==' and !=' operators. These now use a deep
equality test, so they also work for (finite) attribute sets and
  lists.

Eelco Dolstra
25eedf085d * Quick and dirty implementation of with'. with e1; e2' is
basically desugared to `let <with> = e1; e2', and `lookupVar' looks
  in each <with> in the environment chain for an attribute with the
  specified name.

ef8bd919fc * Implement `...' and default function arguments. 2010-03-25 12:45:23 +00:00
Eelco Dolstra
8a10360c91 * Simplify @-patterns: only {attrs}@name' or name@{attrs}' are now
allowed.  So `name1@name2', `{attrs1}@{attrs2}' and so on are now no
  longer legal.  This is no big loss because they were not useful
  anyway.

  This also changes the output of builtins.toXML for @-patterns
  slightly.
2010-03-25 12:19:41 +00:00

0910ae9568 * Start of an evaluator that uses call-by-need (with thunk updating)
instead of (memoised) call-by-name.

13cce8ec45 Making 'bin2c' to be built with the compiler for the local system.
I copied the configure.ac code about CC_FOR_BUILD from libX11.

05e15049a5 Show the build user's group in /etc/group in chroots.
* src/libstore/build.cc (nix::DerivationGoal::startBuilder): Create
  /etc/group showing the build user's group.

Ludovic Courtès
c752c9f41a Fix thinko in r20547.

2e8eaca573 Clear supplementary groups of `nixbld' in /etc/passwd in chroots.
* src/libstore/build.cc (nix::DerivationGoal::startBuilder): Don't
  display any supplementary groups for `nixbld' in /etc/passwd.

84a4dd5ff0 * Don't use fdatasync since it doesn't work on Snow Leopard.
* Don't refer to config.h in util.hh, because config.h is not
  installed (http://hydra.nixos.org/build/303053).

20186a4079 Don't rely on `PATH_MAX' on GNU. 2010-02-10 15:55:50 +00:00
Eelco Dolstra
4e17be7981 * Revert r19797, and use a simpler solution: just don't monitor build
hooks for silence.  It's unnecessary because the remote nix-store
  command is already monitoring the real build.
2010-02-03 21:38:41 +00:00
Eelco Dolstra
f859a8d3c3 * While waiting for a lock, print a sign of life every 5 minutes.
This prevents remote builders from being killed by the
  `max-silent-time' inactivity monitor while they are waiting for a
  long garbage collection to finish.  This happens fairly often in the
  Hydra build farm.
2010-02-03 21:22:57 +00:00
Eelco Dolstra
4bbbe25802 * Remove most Cygwin-specific code. Cygwin 1.7 implements advisory
POSIX locks, and simulates Unix-style file deletion semantics
  sufficiently.  Note that this means that Nix won't work on Cygwin
  1.5 anymore.
2010-02-02 15:28:36 +00:00
Eelco Dolstra
2723d9b56e * If fdatasync() isn't available, use fsync(). 2010-02-02 11:57:49 +00:00
Eelco Dolstra
07ffdc2862 * Added an option "fsync-metadata" to fsync() changes to
/nix/var/nix/db.
* Removed the function writeStringToFile since it does (almost) the
  same thing as writeFile.
2010-01-29 12:22:58 +00:00
Eelco Dolstra
ad529fb89f * Don't consider a store path valid if its info file exists but is
zero bytes long.  That makes Nix more robust in case of crashes
  (especially on ext4).
2010-01-29 11:53:58 +00:00
Eelco Dolstra
fdcaf37361 * Made `nix-store -qR --include-outputs' much faster if there are
multiple paths specified on the command line (from O(n * m) to O(n +
  m), where n is the number of arguments and m is the size of the
  closure).
2010-01-25 17:18:44 +00:00
Eelco Dolstra
5388944e8d * Make the garbage collector do the right thing when `gc-keep-outputs'
is enabled by not depending on the deriver.
2010-01-25 16:04:32 +00:00
Eelco Dolstra
f0c0277970 * On startup, set the default SIGCHLD handler. This is so that Nix
works correctly in weird environments where the SIGCHLD handler is
  set to "ignore".
2010-01-12 12:22:38 +00:00
Eelco Dolstra
ef92a14bfe * Include config.h before the C library headers, because it defines
_FILE_OFFSET_BITS=64.  Without it, functions like stat() fail on
  large file sizes.  This happened with a Nix store on squashfs:

  $ nix-store --dump /tmp/mnt/46wzqnk4cbdwh1dclhrpqnnz1icak6n7-local-net-cmds > /dev/null
  error: getting attributes of path `/tmp/mnt/46wzqnk4cbdwh1dclhrpqnnz1icak6n7-local-net-cmds': Value too large for defined data type

  $ stat /tmp/mnt/46wzqnk4cbdwh1dclhrpqnnz1icak6n7-local-net-cmds
  File: `/tmp/mnt/46wzqnk4cbdwh1dclhrpqnnz1icak6n7-local-net-cmds'
  Size: 0               Blocks: 36028797018963968 IO Block: 1024   regular empty file

  (This is a bug in squashfs or mksquashfs, but it shouldn't cause Nix
  to fail.)

Eelco Dolstra
945d8218fb * Build correctly against newer ATerm releases. Fixes "error: 'union'
tag used in naming 'struct _ATerm'".
2009-12-16 15:29:50 +00:00
Eelco Dolstra
bcd6cdf0d8 * Give a better error message when trying to build something and
readOnlyMode is set.
2009-12-09 17:45:22 +00:00

13618b191e * Grrr. 2009-11-24 13:28:46 +00:00
Eelco Dolstra
aa5a768720 * GCC 4.4 is stricter about the EOF macro
(http://hydra.nixos.org/build/156340).
2009-11-24 12:56:26 +00:00
Eelco Dolstra
9b8fda796b * Templatise getIntArg / string2Int. 2009-11-24 12:26:25 +00:00
Eelco Dolstra
8022015552 * In the garbage collector, don't count files with a link count > 1 in
the "bytes/blocks freed" statistics.
2009-11-24 10:51:52 +00:00
Eelco Dolstra
f9e766db98 * Randomise the order in which we delete entries to make the collector
less biased towards deleting paths that come alphabetically first
  (e.g. /nix/store/000...).  This matters when using --max-freed etc.
2009-11-24 09:53:18 +00:00
Eelco Dolstra
ca50c83fbb 2009-11-23 21:21:29 +00:00
Eelco Dolstra
3d55f1eb57 * A command `nix-store --query --roots <paths>' to find the garbage
collector roots that point (directly or indirectly) to the given
  paths.
2009-11-23 18:16:25 +00:00
Eelco Dolstra
ae6bf87273 * `nix-store --gc --print-roots': also print the path of the actual
root symlink, not just its target.  E.g.:

  /nix/var/nix/profiles/system-99-link -> /nix/store/76kwf88657nq7wgk1hx3l1z5q91zb9wd-system
2009-11-23 17:23:12 +00:00
Eelco Dolstra
c364d5d1e3 * Made the garbage collector a lot faster. It no longer computes the
complete set of live and dead paths before starting the actual
  deletion, but determines liveness on demand.  I.e. for any path in
  the store, it first tries to delete all the referrers, and then the
  path itself.  This means that the collector can start deleting paths
  almost immediately.
2009-11-23 16:34:24 +00:00
Eelco Dolstra
8824d60fe5 * Remove the --use-atime / --max-atime garbage collector flags. Many
(Linux) machines no longer maintain the atime because it's too
  expensive, and on the machines where --use-atime is useful (like the
  buildfarm), reading the atimes on the entire Nix store takes way too
  much time to make it practical.
2009-11-20 17:12:38 +00:00
Eelco Dolstra
327a232c85 * Remove support for old (before Nix 0.12pre12020) databases. 2009-11-06 01:15:44 +00:00
Eelco Dolstra
8520542071 * When building in a chroot, make a copy of a file if hard-linking
fails.  This is likely to happen after a `nix-store --optimise',
  because some files may have 32000 links (NIX-111).
2009-10-22 08:28:33 +00:00
Eelco Dolstra
6b9f6b0222 * Remove a prototype for a function that no longer exists. 2009-10-22 08:12:38 +00:00
Eelco Dolstra
deb342fb08 * builtins.trace: in the common case that the value is a string, then
show the string, not the ATerm, so we get `trace: bla' instead of
  `trace: Str("bla",[])'.
2009-10-22 08:10:12 +00:00
Eelco Dolstra
437077c39d * Added a primop unsafeDiscardOutputDependency needed by Disnix to
pass derivation paths to a builder without actually building them.
2009-10-21 15:05:30 +00:00
Eelco Dolstra
6f7d7bc1de * Give a useful error message when an evaluation error occurs while
trying to upgrade a package.
2009-10-13 09:30:17 +00:00
Sander van der Burg
53a4981fa2 Added optional parameter which adds -lnsl -lsocket to make the Nix package manager work on OpenSolaris 2009-10-08 14:50:37 +00:00
Eelco Dolstra
96f1517831 * Support platforms that don't have O_ASYNC (e.g. OpenSolaris
apparently).
2009-09-30 11:32:04 +00:00
Eelco Dolstra
1a8f8fd86f * OpenSolaris compatibility. 2009-09-30 09:54:29 +00:00
Eelco Dolstra
c7057fc1f2 * And some more. 2009-09-24 07:39:55 +00:00
Eelco Dolstra
193f59e077 * Fix a build failure on Fedora 11. rename() needs <stdio.h>. 2009-09-24 07:21:29 +00:00
Eelco Dolstra
1332dd1ed3 * tryEval shouldn't catch all exceptions of type Error, since not all
of them leave the evaluator in a continuable state.  Also, it should
  be less chatty.
2009-09-23 19:19:26 +00:00

676e07902e * Darwin hack. 2009-09-23 18:04:55 +00:00
Eelco Dolstra
64e89980e8 * Create some state directories automatically as a convenience. 2009-09-23 17:05:51 +00:00
