Eelco Dolstra 698e880c9f * Tricky: make sure that the accessor count is not reset to 0 if 
recovery fails.
 2004-01-13 12:36:43 +00:00
Eelco Dolstra 23fbc72f5d * Print error messages, not debug messages. 2004-01-13 11:53:12 +00:00
Eelco Dolstra 4c4fe7a114 * Changed the extension for store expressions from ".nix" to ".store" 
(following the Usenix paper).
 2004-01-12 10:44:48 +00:00
Eelco Dolstra 46a71c857c * Option --force-realise' in nix-store --query'. 2004-01-09 14:18:28 +00:00
Eelco Dolstra 7959354379 * Upgraded to Berkeley DB 4.2.52. The main advantage of 4.2 is that 
it automatically removes log files when they are no longer needed.

  *** IMPORTANT ***

  If you have an existing Nix installation, you must checkpoint the
  Nix database to prevent recent transactions from being undone.  Do
  the following:

  - optional: make a backup of $prefix/var/nix/db.

  - run `db_checkpoint' from Berkeley DB 4.1:
  
    $ db_checkpoint -h $prefix/var/nix/db -1

  - optional (?): run `db_recover' from Berkeley DB 4.1:

    $ db_recover -h $prefix/var/nix/db

  - remove $prefix/var/nix/db/log* and $prefix/var/nix/db/__db*

Eelco Dolstra 4a373a3e9a * Implemented Eelco V.'s `nix-env -I' command to specify the default 
path of the Nix expression to be used with the import, upgrade, and
  query commands.  For instance,

  $ nix-env -I ~/nixpkgs/pkgs/system/i686-linux.nix

  $ nix-env --query --available   [aka -qa]
  sylpheed-0.9.7
  bison-1.875
  pango-1.2.5
  subversion-0.35.1
  ...

  $ nix-env -i sylpheed

  $ nix-env -u subversion

  There can be only one default at a time.

* If the path to a Nix expression is a symlink, follow the symlink
  prior to resolving relative path references in the expression.
 2004-01-05 16:26:43 +00:00
Eelco Dolstra f83c5e3e5f * Implemented Eelco V.'s `-p' command to switch profiles. It switches 
the symlink ~/.nix-userenv to the given argument (which defaults to
  .../links/current).  /etc/profile.d/nix-profile creates this symlink
  if it doesn't exist yet.  Example use:

  $ nix-env -l my_profile -i foo.nix subversion quake
  $ nix-env -p my_profile

  I don't like the term "profile".  Let's deprecate it :-)
 2004-01-05 11:18:59 +00:00
Eelco Dolstra 94175e978a * RPM spec file. 
* Respect DESTDIR variable.
 2003-12-30 20:09:00 +00:00
Eelco Dolstra 392b7e0f8e * Fixed a bug in the upgrade operation. 2003-12-23 22:13:36 +00:00
Eelco Dolstra 833f2fc92d * GCC 2.95 compatibility. 2003-12-22 16:40:46 +00:00
Eelco Dolstra cf0287c09e * Upgrade operation in `nix-env'. For instance, you can say 
nix-env -u foo.nix strategoxt

  to replace the installed `strategoxt' derivation with the one from `foo.nix', if 
  the latter has a higher version number.  This is a no-op if `strategoxt' is not 
  installed.  Wildcards are also accepted, so

    nix-env -u foo.nix '*'

  will replace any installed derivation with newer versions from `foo.nix', if 
  available.

  The notion of "version number" is somewhat ad hoc, but should be useful in most 
  cases, as evidenced by the following unit tests for the version comparator:

    TEST("1.0", "2.3", -1);
    TEST("2.1", "2.3", -1);
    TEST("2.3", "2.3", 0);
    TEST("2.5", "2.3", 1);
    TEST("3.1", "2.3", 1);
    TEST("2.3.1", "2.3", 1);
    TEST("2.3.1", "2.3a", 1);
    TEST("2.3pre1", "2.3", -1);
    TEST("2.3pre3", "2.3pre12", -1);
    TEST("2.3a", "2.3c", -1);
    TEST("2.3pre1", "2.3c", -1);
    TEST("2.3pre1", "2.3q", -1);

  (-1 = less, 0 = equal, 1 = greater)

* A new verbosity level `lvlInfo', between `lvlError' and `lvlTalkative'.  This is 
  the default for `nix-env', so without any `-v' flags users should get useful 
  output, e.g.,

$ nix-env -u foo.nix strategoxt
upgrading `strategoxt-0.9.2' to `strategoxt-0.9.3'
 2003-12-22 16:04:00 +00:00
Eelco Dolstra f3c9783846 * Version numbers can be omitted in install/uninstall. E.g., 
nix-env -i foo.nix subversion

  The version number part of a derivation name is defined as everything following the 
  first dash not followed by a letter.
 2003-12-21 23:58:56 +00:00
Eelco Dolstra a81b621202 * -u' -> -e'. 
* `--link' / `-l' flag to specify the switch symlink to use (by default, 
  /nix/var/nix/links/current).
 2003-12-21 22:34:41 +00:00
Eelco Dolstra 528f1d1867 * Bug fix: parallel builds of the same derivation failed due to lock file removal. 2003-12-21 17:09:16 +00:00
Eelco Dolstra cff6fd22eb * Allow successors that don't exist but have a substitute. 
* Integrity: check in successor / substitute registration whether
  the target path exists or has a substitute.
 2003-12-05 11:05:19 +00:00
Eelco Dolstra 0d3a1a8582 * Add missing files to `make dist'. 2003-12-02 12:37:37 +00:00
Eelco Dolstra 0c804c6775 * Regression fix: query flags (e.g., "-qsf") were broken. 2003-12-02 10:21:40 +00:00
Eelco Dolstra 078e20885e * Help text for all (non-script) programs, so no more: 
$ nix-instantiate --help
error: unknown flag `--help`
Try `nix-instantiate --help' for more information.

:-)
 2003-12-01 15:55:05 +00:00
Eelco Dolstra 83ffd4f282 * Fix `make check'. 2003-12-01 14:40:24 +00:00
Eelco Dolstra 5d2b424804 * Use a system name that does not include the OS manufacturer (i.e., 
"i686-linux" instead of "i686-suse-linux").
 2003-12-01 14:36:50 +00:00
Eelco Dolstra ba73f94b3b * Another fix. 2003-11-25 13:03:48 +00:00
Eelco Dolstra 66c115ef5f * More `make dist' fixes. 2003-11-25 13:01:21 +00:00
Eelco Dolstra c3ee8c9166 * `make dist' fix. 2003-11-25 12:35:52 +00:00
Eelco Dolstra 6e8c19714a * Allow integer bindings in derivations. 2003-11-25 12:05:48 +00:00
Eelco Dolstra b857267893 * Allow the top-level expression to be a derivation. 
* Hack: `nix-env -i *' installs all available derivations.
 2003-11-24 11:01:19 +00:00
Eelco Dolstra c9cb1fa21f * Bug fix in path invalidation. 
* More consistency checks.
 2003-11-24 09:24:52 +00:00
Eelco Dolstra af7e6fe22e * Don't use a hard-coded path. 2003-11-22 21:12:36 +00:00
Eelco Dolstra 9486dda115 * Fix nix-push. 2003-11-22 20:39:51 +00:00
Eelco Dolstra ab0bc4999a * Maintain integrity of the substitute and successor mappings when 
deleting a path in the store.
* Allow absolute paths in Nix expressions.
* Get nix-prefetch-url to work again.
* Various other fixes.
 2003-11-22 18:45:56 +00:00
Eelco Dolstra 40d9eb14df * Fix the garbage collector. 2003-11-22 15:58:34 +00:00
Eelco Dolstra 7a02d95418 * Remove lock files after building. 2003-11-21 16:05:19 +00:00
Eelco Dolstra 06208d1d86 * Uninstallation. 2003-11-21 14:23:18 +00:00
Eelco Dolstra 2e9042bd1e * Uninstall command (doesn't work yet). 2003-11-20 13:48:48 +00:00
Eelco Dolstra e0b5a492f5 * Installation: add the previously installed packages. Switch to the new 
configuration.
* Status queries.
 2003-11-19 21:32:03 +00:00
Eelco Dolstra 9898746ef3 * nix-env: a tool to manage user environments. 
* Replace all directory reading code by a generic readDirectory()
  function.
 2003-11-19 17:27:16 +00:00
Eelco Dolstra fd7ac09f10 * Refactoring (step 2). 2003-11-19 12:03:01 +00:00
Eelco Dolstra ac68840e79 * Refactoring: put the Nix expression evaluator in its own library so 
that it can be used by multiple programs.
 2003-11-19 11:35:41 +00:00
Eelco Dolstra 2be8b5917a * Use `sdftable -s' to get warnings about the grammar. 
* Several bug fixes in the grammar.
* Allow one-line comments (#... and //...) to end in EOF.
 2003-11-19 10:04:03 +00:00
Eelco Dolstra dfc9c64ead * "Fix expression" -> "Nix expression". 
* More refactoring.
 2003-11-18 12:06:07 +00:00
Eelco Dolstra b1117ef29d * nix -> nix-store, fix -> nix-instantiate. 2003-11-18 11:38:25 +00:00
Eelco Dolstra ce92d1bf14 * "Nix expression" -> "store expression". 
* More refactoring.
 2003-11-18 11:22:29 +00:00
Eelco Dolstra 9f0f020929 * libnix -> libstore. 2003-11-18 10:55:27 +00:00
Eelco Dolstra 8798fae304 * Source tree refactoring. 2003-11-18 10:47:59 +00:00
Eelco Dolstra 45610ae675 * An forward non-random access input iterator class for ATermLists. 2003-11-16 18:31:29 +00:00
Eelco Dolstra 3e5a019a07 * Some utility functions for working with ATerms. 2003-11-16 17:46:31 +00:00
Eelco Dolstra 06ae269c7c * Do not filter when parsing. This is much faster. 
* Add some rejections and lexical restrictions to the grammar to make
  this work.
 2003-11-10 11:00:38 +00:00
Eelco Dolstra 15801c88fa * Turned the msg() and debug() functions into macros, since they 
turned out to be a huge performance bottleneck (the text to printed
  would always be evaluated, even when it was above the verbosity
  level).  This reduces fix-ng execution time by over 50%.

  gprof(1) is very useful. :-)
 2003-11-09 10:35:45 +00:00
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.
 2003-11-03 20:30:40 +00:00
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.
 2003-09-11 10:23:55 +00:00
Eelco Dolstra d930a9bc5a * Added some missing #includes. 2003-09-11 08:31:29 +00:00
Eelco Dolstra 803a924b77 * Make nicer dot graphs. Also show the inner structure of slices. 2003-09-03 14:49:58 +00:00
Eelco Dolstra c0bbed0959 * Factored out dot graph generation into a separate file. 2003-09-03 11:20:18 +00:00
