e17e95a828 * Print a shared textual ATerm if the term if very large. Due to 
substitutions, Fix terms are very large when printed as trees (in 
  memory, they are quite compact due to sharing).

0690c1c9c0 * Work around problems with the ATerm library. 
The ATerm library doesn't search the heap for pointers to ATerms
  when garbage collecting.  As a result, C++ containers such as
  `map<ATerm, ATerm>' will cause pointer to be hidden from the garbage
  collector, causing crashes.  Instead, we now use ATermTables.

e2655aa332 * Shorter list syntax ([a b c] instead of [a, b, c]). 2003-11-03 11:59:35 +00:00

ad0976f8d5 * Grammar changes. Attributes in attribute sets are now delimited with 
semicolons instead of comma's.  Final semicolon in the set is optional.

a2a9bacd82 * Filter the substitution list when descending into a recursive 
attribute set.

9210d4d530 * Working evaluator. 
* Mutually recursive attribute sets.
* Print evaluator efficiency statistics.

f1c1a3c97f * Allow empty attribute (argument) sets. 2003-10-31 12:21:01 +00:00
Eelco Dolstra
7db08cc924 * Use SGparseString() instead of SGparseFile() because the latter is 
buggy.  It fails to clear an internal variable (SG_textIndex)
  between invocations, so it can be called only once during a program
  execution.
 2003-10-31 11:22:56 +00:00

403cb9327f * Factor out evaluation into a separate file. 2003-10-30 16:48:26 +00:00
Eelco Dolstra
9f8f39aa3c * Clean up the imploded parse tree. Quotes around strings are 
removed, paths are absolutised relative to the path containing the
  expression we just parsed, and integer literals are converted to
  actual integers.

e537844f4e * Bottomup rewrite function. 2003-10-30 16:11:24 +00:00
Eelco Dolstra
442b09ea33 * Don't use a search path. 2003-10-30 16:10:56 +00:00

933b3f677d * Attribute selection operator. 2003-10-30 16:10:20 +00:00
Eelco Dolstra
b95a3dc45b * Basic grammar and parser for the Fix language. We use libsglr and 
friends to do the parsing.  The parse table is embedded in the Fix
  executable using bin2c, which converts an arbitrary file into a C
  character array.

4d728f6a36 * Forked new version of Fix. 2003-10-29 15:05:18 +00:00

f31661a3b5 * Add sdf2-bundle to externals. 2003-10-29 15:04:50 +00:00

7102455cba * Don't cache the manifest. 2003-10-27 18:43:09 +00:00
Eelco Dolstra
92eea8fc4e * Fix a race condition in addTextToStore(). 2003-10-23 10:51:55 +00:00
Eelco Dolstra
c4e7d324b8 * Use writeFull(). 2003-10-22 13:29:40 +00:00
Eelco Dolstra
9d95aafe8c * Ad hoc per-package logging. When Nix performs a derivation, it now 
writes stdout/stderr of the builder to ${prefix}/var/log/nix/x,
  where x is the file name of the derivation expression, e.g.,

    /nix/var/log/nix/54256391624be04fcb426048ae3ea0a4-d-pan-0.14.2.nix

  Note that consecutive builds of the same expression overwrite,
  rather than append to, existing log files.

143427f90b * Dead code removal. 2003-10-22 10:53:46 +00:00
Eelco Dolstra
4a8948b7a6 * Some wrapper classes to ensure that file descriptors / directory 
handles are closed when they go out of scope.

0eab306466 * NarPath -> NarName. 2003-10-20 09:08:44 +00:00

a0a7a4e087 * Remove some debug output. 2003-10-16 19:24:04 +00:00
Eelco Dolstra
0791282b2f * Substitutes and nix-pull now work again. 
* Fixed a segfault caused by the buffering of stderr.
* Fix now allows the specification of the full output path.  This
  should be used with great care, since it by-passes the normal hash
  generation.
* Incremented the version number to 0.4 (prerelease).
 2003-10-16 16:29:57 +00:00

ab5e8767fa * Get nix-push to work again. 
* Fixed svn:ignore on externals/.

c78bf11524 * Enable buffering of stderr in C++. 2003-10-16 11:55:37 +00:00
Eelco Dolstra
f7c7aad135 * Upgraded to Berkeley DB 4.1.25 and do not synchronously flush the 
log on commit.  This means that there is a small change that some
  transactions may be rolled back in case of a system crash, but this
  should not be a problem (it merely might cause some expression
  realisations to be rolled back), and it vastly improves performance.

* Upgraded to ATerm 2.0.5 (which also includes Armijn's 64-bit
  patches).

181aa3dc41 * Don't sort the result of `--query --list'. 2003-10-16 08:06:19 +00:00
Eelco Dolstra
ebff82222c * Refactoring: move all database manipulation into store.cc. 
* Removed `--query --generators'.
 2003-10-15 12:42:39 +00:00
Eelco Dolstra
5fc7127643 * Keep sources (derivation expression) by default, `--no-source' to 
override.
 2003-10-15 10:34:50 +00:00
Eelco Dolstra
c190f051ac * Automatically recover the database in case of a crash. 2003-10-14 15:33:00 +00:00
Eelco Dolstra
1d61e473c8 * New query `nix --query --predecessors' to print the predecessors of 
a Nix expression.

0abe185688 * `nix --verify': check and repair reverse mapping for successors. 2003-10-10 15:14:29 +00:00
Eelco Dolstra
d3d5e77810 * Reverse mappings for the successor and substitute mappings. 2003-10-10 14:46:28 +00:00
Eelco Dolstra
1eb4da156c * Performance improvement: don't register already registered terms, 
thus greatly reducing the number of db transactions.
 2003-10-10 13:22:29 +00:00
Eelco Dolstra
08b7319f5b * Follow successors by default (use `--no-successors' to override). 2003-10-09 15:38:31 +00:00
Eelco Dolstra
6409c215e5 * Fixed nix-switch. 2003-10-09 15:37:20 +00:00
Eelco Dolstra
6baa2c4420 * Get rid of identifiers since they are redundant now. This greatly 
simplifies stuff.

* The format of Nix expressions and the database schema changed
  because of this, so it's best to delete old Nix installations.
