Eelco Dolstra 90e26d392c * Allow null in derivation bindings. 2003-11-06 15:24:31 +00:00
Eelco Dolstra cfaea07444 * `null' is a nullary primop. 2003-11-06 14:41:49 +00:00
Eelco Dolstra 569e7940f8 * Allow `+' in path names. 2003-11-06 14:41:29 +00:00
Eelco Dolstra fa18f1f184 * Assertions.
* Logical operators (!, &&, ||, ->).
2003-11-05 16:27:40 +00:00
Eelco Dolstra 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).
2003-11-05 16:20:57 +00:00
Eelco Dolstra 80bb477cc4 * Default function arguments. 2003-11-05 15:34:12 +00:00
Eelco Dolstra 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.

Eelco Dolstra ff31324278 * Ignore options passed to the aterm library. 2003-11-03 18:21:53 +00:00
Eelco Dolstra e2655aa332 * Shorter list syntax ([a b c] instead of [a, b, c]). 2003-11-03 11:59:35 +00:00
Eelco Dolstra ad0976f8d5 * Grammar changes. Attributes in attribute sets are now delimited with
semicolons instead of comma's.  Final semicolon in the set is optional.
2003-11-03 10:21:30 +00:00
Eelco Dolstra 40986312bb * Boolean constants. 2003-11-02 17:36:15 +00:00
Eelco Dolstra adf9a45469 * Primops: baseNameOf, toString. 2003-11-02 16:31:35 +00:00
Eelco Dolstra c8268ca991 * Fast builds. 2003-11-01 23:29:02 +00:00
Eelco Dolstra 7de1b2a698 * Print the exit code of the builder. 2003-11-01 21:11:52 +00:00
Eelco Dolstra 1610444671 * Conditions, string equality. 2003-11-01 19:15:08 +00:00
Eelco Dolstra 1b4184ccbb * Let syntax. 2003-11-01 19:10:41 +00:00
Eelco Dolstra a2a9bacd82 * Filter the substitution list when descending into a recursive
attribute set.
2003-11-01 19:10:19 +00:00
Eelco Dolstra 9210d4d530 * Working evaluator.
* Mutually recursive attribute sets.
* Print evaluator efficiency statistics.
2003-10-31 17:09:31 +00:00
Eelco Dolstra 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
Eelco Dolstra 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.
2003-10-30 16:18:40 +00:00
Eelco Dolstra 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
Eelco Dolstra 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.
2003-10-29 16:05:03 +00:00
Eelco Dolstra 4d728f6a36 * Forked new version of Fix. 2003-10-29 15:05:18 +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.
2003-10-22 11:04:57 +00:00
Eelco Dolstra 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.
2003-10-22 10:48:22 +00:00
Eelco Dolstra c62433751d * Finished refactoring the tree. 2003-10-20 10:05:01 +00:00
Eelco Dolstra 53e376d836 * Refactored the source tree. 2003-10-20 09:20:11 +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
Eelco Dolstra 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).
2003-10-16 08:52:44 +00:00
Eelco Dolstra 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 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.
2003-10-10 15:25:21 +00:00
Eelco Dolstra 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 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.
2003-10-08 15:06:59 +00:00
Eelco Dolstra b9f4942bd2 * string -> Path. 2003-10-07 14:37:41 +00:00
Eelco Dolstra 5d4171f7fb * Synchronise terminology with the ICSE paper (e.g., slice -> closure,
fstate -> Nix expression).
* Fix src/test.cc.
2003-10-07 12:27:49 +00:00
Eelco Dolstra e78f753aa8 * Include the right files in a distribution. 2003-10-02 12:22:19 +00:00
Eelco Dolstra 4193d62e08 * Nix now respects $TMPDIR for the creation of temporary build directories.
* Retry creation of a temporary directory (with a different name) in the 
  case of EEXIST.
2003-10-02 11:55:38 +00:00
Eelco Dolstra 1c7d6bf5fc * Removed references to char_traits so that boost/format also works on
GCC 2.95.
