Eelco Dolstra bf87cc44b4 * Sync with the trunk. 2010-06-21 07:55:38 +00:00
Eelco Dolstra b57189174f * In importPath() and exportPath(), lock the temporary directory to 
prevent it from being deleted by the garbage collector.
 2010-06-14 08:34:48 +00:00
Eelco Dolstra f16fe2af8d * builtins.toXML: propagate the string context. This is a regression 
from the old ATerm-based evaluator.
 2010-06-10 10:29:50 +00:00
Eelco Dolstra d1f6c0cbe3 * Replacing ValidPath rows doesn't work because it causes a constraint 
violation of the Refs table.  So don't do that.
 2010-06-08 13:38:28 +00:00
Eelco Dolstra 07ca66cf24 * Applied a patch from David Brown to prevent `nix-store --optimise' 
from failing on rename() on BtrFS.
 2010-06-04 13:56:11 +00:00
Eelco Dolstra 1ab67cf437 2010-06-02 09:43:04 +00:00

Eelco Dolstra a443c7573b * Hack to allow derivations to disable chroot builds by setting the 
attribute "__noChroot = true" (requested by Rob).
 2010-06-01 10:01:14 +00:00

Eelco Dolstra b92a2e5cc2 * Sync with the trunk. 2010-05-20 12:36:03 +00:00
Eelco Dolstra 93cd5a4a13 * The << operator on values should be const. 2010-05-18 10:36:37 +00:00
Eelco Dolstra 32539e41d5 * Sync with trunk. 2010-05-16 17:16:00 +00:00

Eelco Dolstra bd25ac2260 * Print attributes in sorted order. 2010-05-12 12:15:49 +00:00
Eelco Dolstra 81a4b4e49b * Implemented tryEval, the last missing primop in the fast-eval 
branch.  Also added a test for tryEval.
 2010-05-12 11:23:44 +00:00
Eelco Dolstra 1a8eb6e3ec 2010-05-07 15:26:33 +00:00
Eelco Dolstra 83dfa89870 * Sync with the trunk. 2010-05-07 14:46:47 +00:00
Eelco Dolstra 01e58adce0 * Store position info for inherited attributes. 2010-05-07 12:43:57 +00:00
Eelco Dolstra 83d7b89660 * Updated addErrorContext. 2010-05-07 12:33:14 +00:00
Eelco Dolstra e2d5e40f4f * Keep track of the source positions of attributes. 2010-05-07 12:11:05 +00:00
Eelco Dolstra 84ce7ac76f * Store attribute positions in the AST and report duplicate attribute 
errors with position info.
* For all positions, use the position of the first character of the
  first token, rather than the last character of the first token plus
  one.
 2010-05-06 16:46:48 +00:00
Eelco Dolstra a0e3b84fac * Revert r15436. This was a workaround for a bug in btrfs which seems 
to have been fixed now.
 2010-05-04 12:42:58 +00:00
Eelco Dolstra f92c9a0ac5 * Allow unprivileged users to do `nix-store --clear-failed-paths' and 
`nix-store --query-failed-paths'.
 2010-05-04 10:45:10 +00:00
Eelco Dolstra c82782f9a5 2010-04-27 09:05:11 +00:00
Eelco Dolstra ef337f7089 2010-04-26 12:58:12 +00:00
Eelco Dolstra 6199f9b93e * Added a command `nix-store --clear-failed-paths <PATHS>' to clear 
the "failed" status of the given store paths.  The special value `*'
  clears all failed paths.
 2010-04-26 12:56:42 +00:00
Eelco Dolstra 2398af13c5 * Add an command `nix-store --query-failed-paths' to list the cached 
failed paths (when using the `build-cache-failure' option).
 2010-04-26 12:43:42 +00:00
Eelco Dolstra 2be6118f4c * Don't need the test program anymore. 2010-04-23 09:09:32 +00:00
Eelco Dolstra 0bc468f195 * Simplify the implementation of `with'. This gives a 7% speedup in 
evaluating the NixOS system configuration.
 2010-04-22 15:08:09 +00:00
Eelco Dolstra ebade9ff8b * Check for duplicate attribute names / function arguments. `make 
check' now succeeds :-)
* An attribute set such as `{ foo = { enable = true; };
  foo.port = 23; }' now parses.  It was previously rejected, but I'm
  too lazy to implement the check.  (The only reason to reject it is
  that the reverse, `{ foo.port = 23; foo = { enable = true; }; }', is
  rejected, which is kind of ugly.)
 2010-04-22 11:02:24 +00:00
Eelco Dolstra 2d7636529f * String equality tests should take the context into account. All the 
evaluation test cases now succeed.
 2010-04-22 09:54:11 +00:00
Eelco Dolstra 6bbfe95e30 * Don't use an ostringstream in unparseDerivation(), because it's 
slow.  A `nix-env -qa --drv-path \*' on Nixpkgs was spending 40% of
  its time in unparseDerivation() because of this (now 11%).
 2010-04-21 19:25:50 +00:00
Eelco Dolstra 6f0f16497a * Fix the interpretation of ''\<character> in indented strings. 2010-04-21 16:18:27 +00:00
Eelco Dolstra 0777448ca6 * Fixed builtins.genericClosure. 2010-04-21 15:57:11 +00:00
Eelco Dolstra fe2d869e04 * Store user environment manifests as a Nix expression in 
$out/manifest.nix rather than as an ATerm.

  (Hm, I thought I committed this two days ago...)
 2010-04-21 15:08:58 +00:00
Eelco Dolstra d66ea83a76 * Sync with the trunk. 2010-04-20 09:20:29 +00:00
Eelco Dolstra f3b8833a48 * Drop the dependency on the ATerm library. 2010-04-19 14:51:58 +00:00
Eelco Dolstra efc7a579e8 * Don't use the ATerm library for parsing/printing .drv files. 2010-04-19 13:46:58 +00:00
Eelco Dolstra 55b5ddd3ca * Added parsing of manifests in ATerm format. 2010-04-19 12:10:04 +00:00
Eelco Dolstra b7ff69eb7c * Refactoring: move the user environment stuff into its own module. 2010-04-19 10:47:56 +00:00
Eelco Dolstra 5c31995bb8 * Updated some more primops. 2010-04-16 15:13:47 +00:00
Eelco Dolstra 8bb0210fea * _combineChannels shouldn't be an integer. 2010-04-16 14:07:52 +00:00
Eelco Dolstra 8ca4a001cb * Improve sharing a bit. 2010-04-16 14:03:26 +00:00
Eelco Dolstra 497e4ad126 * Remove some redundant tests. 2010-04-16 13:51:01 +00:00
Eelco Dolstra 02c1dac909 * In an nested with' where the inner with is a variable (with ...; 
with someVar; ...'), the contents of the variable would be
  clobbered.  (The attributes in the outer `with' were added to the
  variable.)
 2010-04-16 13:44:02 +00:00
Eelco Dolstra 04c4bd3624 * Store lists as lists of pointers to values rather than as lists of 
values.  This improves sharing and gives another speed up.
  Evaluation of the NixOS system attribute is now almost 7 times
  faster than the old evaluator.
 2010-04-15 00:37:36 +00:00
Eelco Dolstra e41b5828db * Better stats. 2010-04-14 23:48:46 +00:00
Eelco Dolstra d39d3c6264 * Implemented inherit. 2010-04-14 23:25:05 +00:00
Eelco Dolstra 267dc693d2 * Fix builtins. 2010-04-14 22:59:39 +00:00
Eelco Dolstra 81de12bc8f * Refactoring: move variable uses to a separate class. 2010-04-14 15:14:23 +00:00
Eelco Dolstra 110d155778 * Implemented withs. 2010-04-14 15:01:04 +00:00
Eelco Dolstra 9985230c00 * After parsing, compute level/displacement pairs for each variable 
use site, allowing environments to be stores as vectors of values
  rather than maps.  This should speed up evaluation and reduce the
  number of allocations.
 2010-04-14 14:42:32 +00:00
Eelco Dolstra 816dd3f061 * Remove more obsolete code. 2010-04-14 12:49:05 +00:00
Eelco Dolstra 011b5da0f4 * Get nix-env to compile again. 2010-04-14 09:39:06 +00:00
Eelco Dolstra 85d13c8f93 * Change the semantics of "with" so that inner "withs" take 
precedence, i.e. `with {x=1;}; with {x=2;}; x' evaluates to 2'.
  This has a simpler implementation and seems more natural.  There
  doesn't seem to be any code in Nixpkgs or NixOS that relies on the
  old behaviour.
 2010-04-14 08:37:08 +00:00
Eelco Dolstra 816f9c0f6f * Use std::tr1::unordered_set instead of std::set for the symbol 
table.  This gives a 10% speed increase on `nix-instantiate
  /etc/nixos/nixos -A system --readonly-mode'.
 2010-04-13 14:34:11 +00:00
Eelco Dolstra 7d47498b5e * Evaluate lets directly (i.e. without desugaring to `rec { attrs...; 
<let-body> = e; }.<let-body>).  This prevents the unnecessary
  allocation of an attribute set.
 2010-04-13 13:42:25 +00:00
Eelco Dolstra ac1e8f40d4 * Use a symbol table to represent identifiers and attribute names 
efficiently.  The symbol table ensures that there is only one copy
  of each symbol, thus allowing symbols to be compared efficiently
  using a pointer equality test.
 2010-04-13 12:25:42 +00:00
Eelco Dolstra 10e8b1fd15 * Finished the ATerm-less parser. 2010-04-12 23:33:23 +00:00
Eelco Dolstra 0d272fca79 * Remove some obsolete functions. 2010-04-12 23:31:47 +00:00
Eelco Dolstra d4f0b0fc6c * Indented strings. 2010-04-12 22:03:27 +00:00
Eelco Dolstra a60317f20f * More missing constructs. 2010-04-12 21:21:24 +00:00
Eelco Dolstra 4d6ad5be17 * Don't use ATerms for the abstract syntax trees anymore. Not 
finished yet.
 2010-04-12 18:30:11 +00:00
Eelco Dolstra ed711f73bc * Don't use ATerms to represent integers in the lexer. 2010-04-12 10:38:18 +00:00
Eelco Dolstra db90b88e65 * Hack to support builderDefs expressions. 2010-04-12 09:50:20 +00:00
Eelco Dolstra 4e49002576 * Doh. 2010-04-12 09:45:00 +00:00
Eelco Dolstra c3f228f296 2010-04-12 09:14:27 +00:00
Ludovic Courtès 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".
 2010-04-09 21:30:55 +00:00
Eelco Dolstra f3dc7ab877 * Keep more statistics about stack space usage. 
* Reduce stack space usage.
 2010-04-09 12:00:49 +00:00
Eelco Dolstra 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.
 2010-04-08 11:25:14 +00:00
Eelco Dolstra af2a372bb0 * Update autoCallFunction() and findAlongAttrPath(). 2010-04-07 15:47:06 +00:00
Eelco Dolstra 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
Eelco Dolstra 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).
 2010-04-01 14:35:03 +00:00
Eelco Dolstra 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 :-)
 2010-03-31 19:52:29 +00:00
Eelco Dolstra d8cd3115d8 * Get nix-env to compile. 2010-03-31 19:12:08 +00:00
Eelco Dolstra 55e207b2dc * Cache parse trees to prevent repeated parsing of imported Nix 
expressions.
 2010-03-31 16:14:32 +00:00
Eelco Dolstra 3d94be61ea * Implemented derivations. 2010-03-31 15:38:03 +00:00
Ludovic Courtès 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.
 2010-03-31 12:38:31 +00:00
Eelco Dolstra 13c2adc897 * Implemented `rec { inherit ...; }'. 2010-03-31 11:05:39 +00:00
Eelco Dolstra 4c53ca2692 * Compare nulls. 2010-03-31 09:54:12 +00:00
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
Ludovic Courtès eb07a4f1ee Escape `>' signs in the XML output. 
* src/libutil/xml-writer.cc (nix::XMLWriter::writeAttrs): Escape `>'.
 2010-03-31 08:29:01 +00:00
Eelco Dolstra 7f19e03c65 * More primops. 2010-03-30 22:39:48 +00:00
Eelco Dolstra 47df476daa * More operators / primops. 2010-03-30 18:05:54 +00:00
Eelco Dolstra c9170be2bd * More primops. 2010-03-30 15:18:20 +00:00
Eelco Dolstra c3aa615a5f * More primops. 2010-03-30 14:39:27 +00:00
Eelco Dolstra 5b72d8a749 * Implemented `map'. 2010-03-30 13:47:59 +00:00
Eelco Dolstra d78a05ab40 * Make `import' work. 2010-03-30 09:22:33 +00:00
Eelco Dolstra 31428c3a06 * Started integrating the new evaluator. 2010-03-29 14:37:56 +00:00
