Eelco Dolstra 7de5fe2fc2 * Do the path check on the normal form. 2006-10-17 10:57:25 +00:00
Eelco Dolstra 46b631b6c4 * Don't generate an empty drvPath attribute in the manifest. 2006-10-17 10:15:42 +00:00
Eelco Dolstra d7efd76394 * Big cleanup of the semantics of paths, strings, contexts, string 
concatenation and string coercion.  This was a big mess (see
  e.g. NIX-67).  Contexts are now folded into strings, so that they
  don't cause evaluation errors when they're not expected.  The
  semantics of paths has been clarified (see nixexpr-ast.def).
  toString() and coerceToString() have been merged.

  Semantic change: paths are now copied to the store when they're in a
  concatenation (and in most other situations - that's the
  formalisation of the meaning of a path).  So

    "foo " + ./bla

  evaluates to "foo /nix/store/hash...-bla", not "foo
  /path/to/current-dir/bla".  This prevents accidental impurities, and
  is more consistent with the treatment of derivation outputs, e.g.,
  `"foo " + bla' where `bla' is a derivation.  (Here `bla' would be
  replaced by the output path of `bla'.)
 2006-10-16 15:55:34 +00:00
Eelco Dolstra 37c8a664f3 * A helpful message. 2006-10-13 11:49:55 +00:00
Eelco Dolstra e4af398681 * Don't crash when upgrading the Berkeley DB environment. 2006-10-13 11:15:53 +00:00
Eelco Dolstra 7d4567f2cc * Removed URIs from the evaluator (NIX-66). They are now just another 
kind of notation for strings.
 2006-10-11 21:59:33 +00:00
Eelco Dolstra 0c4c5c2020 * Quick hack to fix NIX-67: evaluation result differing if the Nix 
expression resides in the store.
 2006-10-10 21:23:35 +00:00
Eelco Dolstra bd0c40e1e9 * import': unwrap the context. Necessary to make import (x + y)' 
work, where x is a store path.
 2006-10-10 15:07:23 +00:00
Eelco Dolstra 9e08f5efe1 * Documented nix-store --dump / --restore. 2006-10-05 22:57:07 +00:00
Eelco Dolstra 5fd44654db * toXML: propagate the context to allow derivations to be used in the 
argument.
 2006-10-03 15:38:59 +00:00
Eelco Dolstra d20c3011a0 * toFile: added an additional argument to specify the store path 
suffix, e.g., `builtins.toFile "builder.sh" "..."'.
* toFile: handle references to other files correctly.
 2006-10-03 14:55:54 +00:00
Eelco Dolstra ac19b333b3 * Finally, a real "let" syntax: `let x = ...; ... z = ...; in ...'. 2006-10-02 15:52:44 +00:00
Eelco Dolstra 7581cfdee4 * Hack for Bison 2.3 compatability. 2006-10-02 14:43:15 +00:00
Eelco Dolstra 4ad6fb7ea3 * Fix setuid builds. 2006-09-27 21:04:07 +00:00
Eelco Dolstra 3632019b73 * Quick hack to let nix-install-package set the package name properly 
(e.g., "java-front-0.9pre15899" instead of "java-front";
  particularly important when doing upgrades later on).
 2006-09-25 14:00:59 +00:00
Eelco Dolstra e347033f71 * The result of a concatenation with a derivation on the left-hand 
side should be a path, I guess.
* Handle paths that are in the store but not direct children of the
  store directory.
* Ugh, hack to prevent double context wrapping.
 2006-09-24 21:39:57 +00:00
Eelco Dolstra 0e705391db * Primop `toPath' to convert a string to a path. 
* Primop `pathExists' to check for path existence.
 2006-09-24 18:23:32 +00:00
Eelco Dolstra e47e0c2dbe * Builtin function `getEnv' for getting environment variables. 2006-09-24 17:48:41 +00:00
Eelco Dolstra df8873e14a * lessThan primitive for integer comparison. 2006-09-24 15:21:48 +00:00
Eelco Dolstra 2ab4bc44c7 * Builtin function `add' to add integers. 
* Put common test functions in tests/lang/lib.nix.
 2006-09-22 15:29:21 +00:00
Eelco Dolstra d315210612 * Added a builtin function `isList' to test whether a value is a list. 
With this primitive, a list-flattening function can be implemented
  (NIX-55, example is in tests/lang/eval-okay-flatten.nix).
 2006-09-22 14:55:19 +00:00
Eelco Dolstra c02a44183f * Builtin functions head' and tail' to return the head and tail of 
list.  Useful for lots of things, such as implementing a fold
  function (see NIX-30, example is in tests/lang/eval-okay-list.nix).
 2006-09-22 14:46:36 +00:00
Eelco Dolstra 8a1ab709a4 * New builtin functions builtins.{hasAttr, getAttr} to check for 
attribute existence and to return an attribute from an attribute
  set, respectively.  Example: `hasAttr "foo" {foo = 1;}'.  They
  differ from the `?' and `.' operators in that the attribute name is
  an arbitrary expression.  (NIX-61)
 2006-09-22 14:31:55 +00:00
Eelco Dolstra 666babbbfa * Use a bounded amount of memory in scanForReferences() by not reading 
regular files into memory all at once.
 2006-09-22 13:10:30 +00:00
Eelco Dolstra d22d7565f3 * Don't allocate the buffer twice. 2006-09-22 11:28:23 +00:00
Eelco Dolstra b43aeadbc9 * Don't allocate more than SIZE_MAX bytes. 2006-09-22 11:13:35 +00:00
Eelco Dolstra 25df501704 * GC options in nix-store --help (NIX-15). 2006-09-21 19:06:34 +00:00
Eelco Dolstra 4e91d8621f * Fix comment. 2006-09-21 18:52:05 +00:00
Eelco Dolstra 1bdc152931 * Shut up a warning. 2006-09-20 16:36:29 +00:00
Eelco Dolstra 0623359fbc * Print a better error message for wrong hashes (NIX-49). 2006-09-20 16:15:32 +00:00
Eelco Dolstra e0afaf1857 * Wow, that bug has been there since r764. 2006-09-14 22:48:59 +00:00
Eelco Dolstra 86cbd93ec1 * nix-env --switch-generation / --list-generations / 
--delete-generations: lock the profile to prevent (extremely
  unlikely) race conditions.
 2006-09-14 22:33:53 +00:00
Eelco Dolstra 5c38c863bd * Fix a huge gaping hole in nix-env w.r.t. the garbage collector. 
Nix-env failed to call addPermRoot(), which is necessary to safely
  add a new root.  So if nix-env started after and finished before the
  garbage collector, the user environment (plus all other new stuff)
  it built might be garbage collected, leading to a dangling symlink
  chain in ~/.nix-profile...

* Be more explicit if we block on the GC lock ("waiting for the big
  garbage collector lock...").

* Don't loop trying to create a new generation.  It's not necessary
  anymore since profiles are locked nowadays.
 2006-09-14 22:30:33 +00:00
Eelco Dolstra 01d169f817 * Support `++'. 
* More follow restrictions on layout.
 2006-09-11 13:05:15 +00:00
Eelco Dolstra feb63da431 * Remove debug message. 2006-09-08 09:31:07 +00:00
Eelco Dolstra a89a201598 * Missing #include. 2006-09-05 10:32:47 +00:00
Eelco Dolstra fc195519b5 * Sone missing #includes. 2006-09-05 08:54:48 +00:00
Eelco Dolstra bafc1690fc * Move setuid stuff to libutil. 
* Install libexpr header files.
 2006-09-04 22:55:28 +00:00
Eelco Dolstra e5a6c09b12 * Install header files in /nix/include/nix. 2006-09-04 22:41:36 +00:00
Eelco Dolstra 4be5443882 * Remove unnecessary inclusions of aterm2.h. 2006-09-04 22:08:40 +00:00
Eelco Dolstra 2382a729e0 * Don't need extern "C". 2006-09-04 21:50:39 +00:00
Eelco Dolstra e3ce954582 * Compile the lexer as C++ code. Remove all the redundant C/C++ 
marshalling code.
 2006-09-04 21:36:15 +00:00
Eelco Dolstra 75068e7d75 * Use a proper namespace. 
* Optimise header file usage a bit.
* Compile the parser as C++.
 2006-09-04 21:06:23 +00:00
Eelco Dolstra aab8812732 * Store the Nix libraries in ${libdir}/nix instead of ${libdir}. 2006-09-04 15:12:24 +00:00
Eelco Dolstra 7974aae81c * New primop: builtins.toFile, which writes a string into the store 
and returns its path.  This can be used to (for instance) write
  builders inside a Nix expression, e.g.,

  stdenv.mkDerivation {
    builder = "
      source $stdenv/setup
      ...
    ";
    ...
  }
 2006-09-01 12:07:31 +00:00
Eelco Dolstra de90fdf908 * Allow "$" in strings as long as they are not followed by "{". (Too 
bad flex doesn't have lexical restrictions, the current solution
  isn't quite right...)
 2006-09-01 12:04:06 +00:00
Eelco Dolstra c25f688e23 * Doh! Doh! Doh! 2006-08-31 15:38:43 +00:00
Eelco Dolstra 354d58b3d7 * Better error checking. 2006-08-31 11:40:39 +00:00
Eelco Dolstra f93f7b75be * Okay, that's a bit harder than expected. 2006-08-30 13:10:04 +00:00
Eelco Dolstra 3151bdea55 * Uninitialised variable. 2006-08-30 12:00:27 +00:00
Eelco Dolstra 547b119f25 * Support singleton values and nested lists again in `args', but print 
a warning.
 2006-08-29 15:40:49 +00:00
Eelco Dolstra 2132d9ddeb * Fix the ~ operator. 2006-08-29 15:29:38 +00:00
Eelco Dolstra 1ec9f55741 * In toString, deal with nested lists properly (i.e., flatten them). 2006-08-28 21:47:42 +00:00
Eelco Dolstra 1fca76870b * Removed processBinding, instead we now apply toString to all 
derivation attributes to flatten them into strings.  This is
  possible since string can nowadays be wrapped in contexts that
  describe the derivations/sources referenced by the evaluation of the
  string.
 2006-08-28 13:31:06 +00:00
Eelco Dolstra 8a6080eb14 * Refactoring. 2006-08-26 16:48:01 +00:00
Eelco Dolstra 4b66cebe7b * Remove those storePath attribute sets, we don't need 'em. 2006-08-25 17:09:55 +00:00
Eelco Dolstra 3e8dccf6ab * Escape newlines in XML attributes to prevent them from being 
normalised away.
 2006-08-24 15:02:39 +00:00
Eelco Dolstra 215ec2ddc6 * New primop __toXML (or builtins.toXML) to convert an expression to 
an XML representation stored in a string.  This should be useful to
  pass structured information to builders.
 2006-08-24 14:34:29 +00:00
Eelco Dolstra f793caf936 * Refactoring. 2006-08-24 14:16:55 +00:00
Eelco Dolstra da25d80152 * Strict evaluation and XML printing of lists. 2006-08-24 14:03:39 +00:00
Eelco Dolstra 943ab38a0d * Refactoring: move strictEval to libexpr. 2006-08-24 13:39:22 +00:00
Eelco Dolstra f41297fdce * Allow --arg in nix-env as well, example: 
$ nix-env -qa --system-filter \* --arg system '"powerpc-darwin"'

  to override the system from the default value (__currentSystem in
  all-packages.nix).
 2006-08-23 16:33:21 +00:00
Eelco Dolstra 9638f3f393 * Pass the autoArgs to findAlongAttrPath so that "nix-instantiate 
foo.nix -A attr --arg name value" will work if (name, value) is
  needed in the evaluation leading up to "attr".
 2006-08-23 16:20:14 +00:00
Eelco Dolstra b19cebc513 * Quotes. 2006-08-23 15:46:27 +00:00
Eelco Dolstra 38f18aa6d4 * New primop: abort "error message". 2006-08-23 15:46:00 +00:00
Eelco Dolstra 4a053bfdfd * A new primop `builtins', which returns an attribute set containing 
all the primops.  This allows Nix expressions to test for new
  primops and take appropriate action if they're not available.  For
  instance, rather than calling a primop `foo' directly, they could
  say `if builtins ? foo then builtins.foo ... else ...'.
 2006-08-23 14:39:11 +00:00
Eelco Dolstra 24e234a2fa * Print attributes in sorted order, rather than the arbitrary order 
produced by ATermMap.  Necessary for testing.
* `--strict' should also work on stdin.
 2006-08-17 08:53:08 +00:00
Eelco Dolstra 22ba63df16 * More XML output. `--strict' to strictly evaluate attribute sets and 
so on.
* Removed `--print-args', it's subsumed by `--eval-only --xml'.
 2006-08-16 21:59:53 +00:00
Eelco Dolstra 18e4ac0fc6 * `nix-instantiate --{eval|parse}-only --xml': print an XML 
representation instead of an ATerm.
* Indent XML output.
 2006-08-16 10:32:30 +00:00
Eelco Dolstra 2670642733 * Handle carriage returns. Fixes NIX-53. 2006-08-16 10:28:44 +00:00
Martin Bravenboer 3e5b68068b On cygwin, disable the check that the output is not group or world 
writable. File permissions on Cygwin are rather complex, and in this
case this check introduced a problem with build jobs invoke from
outside of Cygwin (MSYS). It seemed almost impossible to fix the
permissions of the directory, so for now this safety check is disabled
on Cygwin.
 2006-08-15 21:37:48 +00:00
Eelco Dolstra 7455fd8835 * Put the value in an attribute. 2006-08-14 14:24:18 +00:00
Eelco Dolstra 4250b641d8 * `nix-store --gc --print-dead': print the total size of the store 
objects that would be freed.
 2006-08-11 20:26:49 +00:00
Eelco Dolstra 92f7dfa5b7 * Don't assume that paths returned by the runtime root finder are 
valid.
 2006-08-11 20:15:20 +00:00
Eelco Dolstra d19b6521fc * New configuration setting `build-max-jobs' which sets the default 
for the `-j' flag (i.e., the maximum number of jobs to execute in
  parallel).  Useful on multi-processor machines.
 2006-08-10 20:19:13 +00:00
Eelco Dolstra f1aa71a92f * Fix the help message wrt --attr. 2006-08-09 15:12:34 +00:00
Eelco Dolstra a18d02e0b0 * Print a warning that the subpath operator (~) is deprecated. 2006-08-09 15:08:47 +00:00
Eelco Dolstra a0607be7f4 * Workaround for a bug (?) in GCC 2.95. 2006-08-07 19:48:38 +00:00
Eelco Dolstra 1854f84e83 * Fix a few warnings. 2006-08-04 17:07:13 +00:00
Eelco Dolstra dcff8cdb76 * Weird issue on Cygwin with the include file order. 2006-08-04 16:01:26 +00:00
Eelco Dolstra 339e6f0e1d * `nix-env -q --xml': show query result in XML format for easier 
automated processing.
 2006-08-03 15:52:09 +00:00
Eelco Dolstra 0e267e2625 * `nix-instantiate --print-args': produce XML output so that the 
result can be used more easily by scripts.
 2006-08-03 14:49:57 +00:00
Eelco Dolstra 4750f6c5ed * Simple class for writing XML files. 2006-08-03 13:21:21 +00:00
Eelco Dolstra 6ac237e242 * Show some progress. 2006-08-01 09:43:41 +00:00
Eelco Dolstra 4661282fde * `nix-instantiate ... --arg NAME VALUE': allow arguments to be passed 
to functions from the command line.
* nix-build: started removing backticks.
 2006-07-28 16:03:28 +00:00
Eelco Dolstra c11839d7b2 * `nix-instantiate --print-args': print out the valid values for 
functions arguments that have a domain.
 2006-07-28 14:01:29 +00:00
Eelco Dolstra ca2238cf81 * Refactoring: get the selection path stuff out of getDerivations() 
and put it into a separate function findAlongAttrPath().
 2006-07-26 15:05:15 +00:00
Eelco Dolstra 2317d8f671 * `nix-instantiate --print-args' prints out the arguments of a 
top-level function.
 2006-07-25 21:21:50 +00:00
Eelco Dolstra 0e6dc72a7a * Applied rbroek's patch from the branch at 
https://svn.cs.uu.nl:12443/repos/trace/buildfarm-control/trunk/ext/nix/,
  with some modifications.  This allows `nix-env -qa' to show the
  attribute path that can be used to unambiguously install a package
  using `nix-env -i -A'.  Example:

    $ nix-env -f top-level/all-packages.nix -qaA subversion xorg-server
    subversionWithJava  subversion-1.2.3
    subversion          subversion-1.3.2
    subversion14        subversion-1.4.0pre-rc1
    xorg.xorgserver     xorg-server-1.1.0
 2006-07-25 16:40:38 +00:00
Eelco Dolstra 5744dd5480 * Support the --attr / -A flag in nix-env as well. So now we can do, 
e.g.,

  $ nix-env -i -A subversion xorg.xorgserver

  The main advantage over using symbolic names is that using attribute
  names is unambiguous and much, much faster.
 2006-07-25 11:53:22 +00:00
Eelco Dolstra 7a3a5d1608 * When there is a domain check, we have to evaluate the argument. 
Can't be lazy!
 2006-07-24 16:49:28 +00:00
Eelco Dolstra f4c5531d92 * New language feature: domain checks, which check whether a function 
argument has a valid value, i.e., is in a certain domain.  E.g.,

    { foo : [true false]
    , bar : ["a" "b" "c"]
    }: ...

  This previously could be done using assertions, but domain checks
  will allow the buildfarm to automatically extract the configuration
  space from functions.
 2006-07-24 16:35:34 +00:00
Eelco Dolstra 57751fdb55 * Refactoring to support domain checks. 2006-07-24 15:16:03 +00:00
Eelco Dolstra a4273156c4 * Use $(libexecdir) to find find-runtime-roots.pl. 2006-07-20 13:21:37 +00:00
Eelco Dolstra ee2cf45d76 * Use debug(). 2006-07-20 12:19:55 +00:00
Eelco Dolstra c15f544356 * Call find-runtime-roots.pl from the garbage collector to prevent 
running applications etc. from being garbage collected.
 2006-07-20 12:17:25 +00:00
Eelco Dolstra 4f3725b167 * Better error messages (especially wrt types). 2006-07-19 15:36:15 +00:00
Eelco Dolstra e10b830251 * Doh! Of couse we cannot memoize across scopes. 2006-07-11 10:29:52 +00:00
Eelco Dolstra d51aede4af * Allow the canonical system name to be specified at runtime in the 
Nix config file.
 2006-07-06 15:30:37 +00:00
Eelco Dolstra a945fb7905 * `nix-env --upgrade --eq': only upgrade if the old version is equal 
to the new version.  This is actually useful.
 2006-06-27 12:17:25 +00:00
Eelco Dolstra dbf6d7e783 * Concurrent GC on Cygwin. 2006-06-20 17:48:10 +00:00
Eelco Dolstra cc51f9c539 * Oops. 2006-06-19 16:35:35 +00:00
Eelco Dolstra 5bb3444032 * _exit() doesn't seem to work right on Cygwin. 2006-06-19 16:24:15 +00:00
Eelco Dolstra b35735d8b2 * On Windows we cannot delete open (lock) files, so we delete lock 
files after we've closed them.  Since this only succeeds if the lock
  is no longer opened by any process, the token trick used on Unix is
  not necessary.
 2006-06-19 14:43:13 +00:00
Eelco Dolstra 0e783e5579 * Write messages to stderr in a slightly more atomic way. Useful when 
there are several parallel processes.
 2006-06-19 14:37:35 +00:00
Eelco Dolstra c937b73622 * Show when we're blocked waiting for a lock. 2006-06-16 10:13:03 +00:00
Eelco Dolstra 588cb0eade * In `nix-env -i|-u|-e', lock the profile to prevent races between 
concurrent nix-env operations on the same profile.  Fixes NIX-7.
 2006-06-15 11:56:49 +00:00
Eelco Dolstra b454977909 * Fix for a problem with BSD's group ownership semantics when the user 
is not in the "wheel" group.
 2006-06-14 11:53:55 +00:00
Eelco Dolstra 23960e92df * Minor cleanup. 2006-06-01 18:13:33 +00:00
Eelco Dolstra 50fe85f016 * For fixed-output derivations, pass the environment variables listed 
in the attribute variable `impureEnvVars' from the caller to the
  builder.
 2006-05-31 09:51:45 +00:00
Eelco Dolstra 1390ce4142 * Not all platforms have sys/select.h. 2006-05-30 11:37:21 +00:00
Eelco Dolstra b1c63dc362 * Don't use badTerm, it gives awful error messages. 2006-05-30 11:31:33 +00:00
Eelco Dolstra 58b4198ed8 * Disable the concurrent garbage collector on Cygwin for now. 2006-05-29 20:46:51 +00:00
Eelco Dolstra d764409d97 * Some Cygwin fixes. 2006-05-24 13:23:20 +00:00
Eelco Dolstra b5988004d6 * Support for srcdir != builddir (NIX-41). 2006-05-12 11:47:45 +00:00
Eelco Dolstra 9d72bf8835 * 64-bit compatibility fixes (for problems revealed by building on an Athlon 
64 running 64-bit SUSE).  A patched ATerm library is required to run Nix
  succesfully.
 2006-05-11 02:19:43 +00:00
Eelco Dolstra c54287eafe * GCC 2.95 compatibility. 2006-05-08 15:15:13 +00:00
Eelco Dolstra 5cabd47394 * Allow function argument default values to refer to other arguments 
of the function.  Implements NIX-45.
 2006-05-08 12:52:47 +00:00
Eelco Dolstra 310e605995 * Show evaluation stats when NIX_SHOW_STATS=1. 2006-05-08 10:00:37 +00:00
Eelco Dolstra 0832956089 * Use the new ATermMap. 2006-05-04 12:21:08 +00:00
Eelco Dolstra d300b4383d * Optimise null-ary term builders. Also declare all term builder 
functions as pure, which might improve performance a bit.
 2006-05-02 21:58:46 +00:00
Eelco Dolstra 68174bdc7d * Use a linked list of substitutions. This reduces the amount of 
copying.
 2006-05-02 21:39:02 +00:00
Eelco Dolstra c791e94aee * Removed a bunch of ATreverses. 2006-05-02 17:51:50 +00:00
Eelco Dolstra b52e711910 * Huge reduction in memory use (2/3 or so on large nix-env -qas 
operations): share ATermMaps between DrvInfos.
 2006-05-02 17:12:03 +00:00
Eelco Dolstra 11ae2d1e7a * Memory reduction: replaced expensive calls to ATmakeApplList by 
ATmakeApplArray, and got rid of ATreverse in substitute().
 2006-05-02 14:07:28 +00:00
Eelco Dolstra dc719e6ba5 * Some preliminaries towards NIX-45. 2006-05-02 13:39:55 +00:00
Eelco Dolstra 7276e194ee * Disallow unescaped $ in string literals. 2006-05-01 15:29:46 +00:00
Eelco Dolstra 0064599a27 * String interpolation. Expressions like 
"--with-freetype2-library=" + freetype + "/lib"

  can now be written as

    "--with-freetype2-library=${freetype}/lib"

  An arbitrary expression can be enclosed within ${...}, not just
  identifiers.

* Escaping in string literals: \n, \r, \t interpreted as in C, any
  other character following \ is interpreted as-is.
  
* Newlines are now allowed in string literals.
 2006-05-01 14:01:47 +00:00
Eelco Dolstra 6cecad2be0 * Allow string concatenations involving derivations, e.g., 
configureFlags = "--with-freetype2-library="
      + freetype + "/lib";
 2006-05-01 09:56:56 +00:00
Eelco Dolstra ef2d4a2da9 * Print a more useful stack trace when an error occurs deep in the 
derivation dependency graph.
 2006-03-24 14:02:44 +00:00
Eelco Dolstra b69e469328 * In `nix-env', look for derivations inside attribute sets that have 
the `recurseForDerivations' attribute set to `true'.
 2006-03-23 16:43:07 +00:00
Eelco Dolstra 49ce8b57dd * Hm. 2006-03-23 16:37:49 +00:00
Eelco Dolstra fdea084c36 * Allow `make check' to work in directories that have symlink 
components.
 2006-03-10 22:27:26 +00:00
Eelco Dolstra 37d1b1cafd * `nix-env -qa --description' shows human-readable descriptions of 
packages (provided that they have a `meta.description' attribute).
  E.g.,

  $ ./src/nix-env/nix-env -qa --description gcc
  gcc-4.0.2   GNU Compiler Collection, 4.0.x (cross-compiler for sparc-linux)
  gcc-4.0.2   GNU Compiler Collection, 4.0.x (cross-compiler for mips-linux)
  gcc-4.0.2   GNU Compiler Collection, 4.0.x (cross-compiler for arm-linux)
  gcc-4.0.2   GNU Compiler Collection, 4.0.x
 2006-03-10 16:20:42 +00:00
Eelco Dolstra 2b3b6c9b34 * In theory, this should reduce the number of ATermMap 
re-allocations.
 2006-03-10 16:14:13 +00:00
Eelco Dolstra 4ada6db1fc * `nix-env -q' now accepts arguments that allow specific derivations 
to be queried, e.g., `nix-env -qa firefox'.  This does require the
  argument '*' to be passed if one wants information about all
  derivations, so the old `nix-env -qa' now is `nix-env -qa "*"'.
 2006-03-10 10:24:46 +00:00
Eelco Dolstra 18c321308d * Ugh, printHash() was very inefficient because it used 
ostringstreams.  Around 11% of execution time was spent here (now
  it's 0.5%).
 2006-03-09 17:07:25 +00:00
Eelco Dolstra b90c00e63f * Regression: semantics of the result of getDerivation() changed. 2006-03-09 15:10:01 +00:00
Eelco Dolstra 922697c8b2 * Big speedup (factor > 2.5) in all nix-env operations that do actual 
instantiation, e.g. "nix-env -i" and "nix-env -qas" (but not
  "nix-env -qa").  It turns out that many redundant calls to
  addToStore(path) were made, which reads and hashes the entire path.
  For instance, the bash bootstrap binary in Nixpkgs would be read and
  hashed many times.  As a result nix-env would spend around 92% of
  its time in the function sha256_block (according to callgrind).
  Some simple memoization fixes this.
 2006-03-09 15:09:18 +00:00
Eelco Dolstra 6dca5c9099 * When obtaining derivations from Nix expressions, ignore all 
expressions that cause an assertion failure (like `assert system ==
  "i686-linux"').  This allows all-packages.nix in Nixpkgs to be used
  on all platforms, even if some Nix expressions don't work on all
  platforms.

  Not sure if this is a good idea; it's a bit hacky.  In particular,
  due to laziness some derivations might appear in `nix-env -qa' but
  disappear in `nix-env -qas' or `nix-env -i'.

  Commit 5000!
 2006-03-08 16:03:58 +00:00
Eelco Dolstra 9088dee9e2 * Some refactoring of the exception handling code so that we can catch 
Nix expression assertion failures.
 2006-03-08 14:11:19 +00:00
Eelco Dolstra fa72ae1e9c * GCC 4.1 compatibility. 2006-03-06 14:40:10 +00:00
Eelco Dolstra c8bfb11b34 * `nix-env (-i|-u) --dry-run' now shows exactly which missing paths 
will be built or substituted.
 2006-03-06 11:21:15 +00:00
Eelco Dolstra 7ba1fd2029 * Regularise help text a bit. 2006-03-06 11:04:39 +00:00
Eelco Dolstra 70dee0f8ca * Flags --to-base32' and --to-base16' to convert between hex and 
base-32 hashes.
 2006-03-01 18:05:47 +00:00
Eelco Dolstra e136532800 * Ouch, parseHash32 was completely broken. All digits >= 4 were 
parsed as 4.

  For a moment I worried that printHash32 was broken, and that would
  have been really, *really* bad ;-)
 2006-03-01 17:59:08 +00:00
Eelco Dolstra 74166f2f44 * db.hh shouldn't depend on the Berkeley DB headers. 2006-03-01 17:44:28 +00:00
Eelco Dolstra d822bf32e4 * Close the database before the destructor runs. 2006-03-01 16:36:35 +00:00
Eelco Dolstra b6780b9e10 * Uninitialised variable. Fixes the --delete test. 2006-03-01 14:39:42 +00:00
Eelco Dolstra b602d2dfdf * Wrong delete. Thanks valgrind. 2006-03-01 14:39:10 +00:00
Eelco Dolstra 458820df6c * Generate valid HTML. 2006-03-01 13:24:47 +00:00
Eelco Dolstra 6b8bb8d74a * Remove dead code. 2006-03-01 12:51:39 +00:00
Eelco Dolstra 46f0cb0869 * In "nix-env -i", print a warning if there are multiple derivations 
with the same name *and* version number, and pick the first one
  (this means that the order in which channels appear in
  ~/.nix-channels matters).  E.g.:

    $ nix-env ii aterm
    warning: there are multiple derivations named `aterm-2.4.2'; using the first one
    installing `aterm-2.4.2'
 2006-02-17 18:11:45 +00:00
Eelco Dolstra 7a3e715980 * Fix for NIX-31: "nix-env -i foo" installing all derivations named 
foo.  Now it will only install the one with the highest version
  number.
 2006-02-17 17:47:54 +00:00
Eelco Dolstra 889ef564fd * Fix the infamous NIX-17: nix-env -i prints misleading messages 
("installing `foo'" followed by "uninstalling `foo'").
 2006-02-17 16:26:28 +00:00
Eelco Dolstra 345a95afe9 * Allow the size of the GC reserved file to be specified in nix.conf 
through the new `gc-reserved-space' option.
 2006-02-16 13:58:10 +00:00
Eelco Dolstra 651ab439cf * A simple hack to fix NIX-18: the garbage collector cannot run when 
the disk is full (because to delete something from the Nix store, we
  need a Berkeley DB transaction, which takes up disk space).  Under
  normal operation, we make sure that there exists a file
  /nix/var/nix/db/reserved of 1 MB.  When running the garbage
  collector, we delete that file before we open the Berkeley DB
  environment.
 2006-02-16 13:19:15 +00:00
Eelco Dolstra d6f586d0ea * Optional switch "--with-openssl=<PATH>" to use OpenSSL's 
implementations of MD5, SHA-1 and SHA-256.  The main benefit is that
  we get assembler-optimised implementations of MD5 and SHA-1 (though
  not SHA-256 (at least on x86), unfortunately).  OpenSSL's SHA-1
  implementation on Intel is twice as fast as ours.
 2006-02-13 19:52:43 +00:00
Eelco Dolstra e8475bbd5b * Use a union. 2006-02-13 18:00:08 +00:00
Eelco Dolstra 2d2e28d02c * Override YYMALLOC and YYFREE so that we can call AT[un]protectMemory 
on the Bison parse stack.  Otherwise, a garbage collect during
  parsing could lead to a crash.
 2006-02-13 13:09:23 +00:00
Eelco Dolstra 982399bb14 * Enable the --attr in nix-build as well (and add -A as an alias). 
Example:

    $ nix-build ./all-packages.nix -A xlibs.libX11

  So finally it's easy to perform a test build of a Nix expression!
 2006-02-10 17:37:35 +00:00
Eelco Dolstra c6120352b3 * In nix-instantiate, allow us to specify a "path" to the 
derivation(s) we're interested, e.g.,

    $ nix-instantiate ./all-packages.nix --attr xlibs.libX11

  List elements can also be selected:

    $ nix-instantiate ./build-for-release.nix --attr 0.subversion

  This allows a non-ambiguous specification of a derivation.  Of
  course, this should also be added to nix-env and nix-build.
 2006-02-10 17:25:59 +00:00
Eelco Dolstra 9e51abc7dc * Make --parse-only work when *not* reading from stdin. 2006-02-10 15:28:47 +00:00
Eelco Dolstra f848a45739 * Cleanup: use the code shared with nix-env. 2006-02-10 15:14:57 +00:00
Eelco Dolstra 4eb637c799 * When querying all derivations, filter out syntactically equal derivations. 2006-02-08 16:15:07 +00:00
Eelco Dolstra 8688e83194 * When evaluating, automatically call functions with default arguments. 2006-02-08 15:22:30 +00:00
Eelco Dolstra 287d0ef41c * Oops, fix breakage. 2006-02-08 14:32:33 +00:00
Eelco Dolstra 39f50db731 * Refactoring: move derivation evaluation to libexpr. 2006-02-08 13:21:16 +00:00
Eelco Dolstra 81de538e46 * Use setsid instead of setpgrp in child processes. This not only 
creates a new process group but also a new session.  New sessions
  have no controlling tty, so child processes like ssh cannot open
  /dev/tty (which is bad).
 2006-02-03 14:20:59 +00:00
Eelco Dolstra b90daaaf6c * When killing a build hook, kill the entire process group (as 
intended).  This ensures that any ssh child processes to remote
  machines are also killed, and thus the Nix process on the remote
  machine also exits.  Without this, the remote Nix process will
  continue until it exists or until its stdout buffer gets full and it
  locks up.  (Partially fixes NIX-35.)
 2006-02-02 16:27:31 +00:00
Eelco Dolstra 6e2eaaec96 * Print a better error message when writing the patched file (e.g., 
"No space left on device" instead of "Success").  Reported by Karina
  Olmos.
 2006-02-01 17:28:13 +00:00
Eelco Dolstra 8291f6d968 * bsdiff updated to 4.3. This makes Nix depend on libbz2. 2006-02-01 16:48:49 +00:00
Eelco Dolstra 9e4ffc43a2 * The "S" bit should be based on the output path, not the derivation path. 2006-02-01 16:47:51 +00:00
Eelco Dolstra db2275cb99 * Oops, the "I" bit in "nix-env -qas" was broken. Reported by Nicolae Vintila. 2006-01-26 23:18:26 +00:00
Eelco Dolstra 1029716a8a * Don't show cycles, they're not very useful. 2006-01-19 15:35:34 +00:00
Eelco Dolstra 5b527901ae * dirOf: return "/", not "", for paths in the root directory. Fixes NIX-26. 2006-01-09 14:52:46 +00:00
Eelco Dolstra 04be39734f * Resolve all symlink components in the location of the temporary 
build directory (TMPDIR, i.e., /tmp).  Fixes NIX-26.
 2006-01-08 17:16:03 +00:00
Eelco Dolstra 0f8d3c871b * More GCC 2.95 compatibility. 2005-12-25 11:29:12 +00:00
Eelco Dolstra 52d20ef124 * Hack around a GCC 2.95 bug. 2005-12-25 02:02:29 +00:00
Eelco Dolstra 1440419b45 * GCC 2.95 compatibility. 2005-12-24 23:32:59 +00:00
Eelco Dolstra 1d2460ee5d * Documentation fixes. 2005-12-24 23:22:05 +00:00
Eelco Dolstra f96d2dea26 * Added a flag --ignore-liveness' to nix-store --delete'. It 
deletes a path even if it is reachable from a root.  However, it
  won't delete a path that still has referrers (since that would
  violate store invariants).

  Don't try this at home.  It's a useful hack for recovering from
  certain situations in a somewhat clean way (e.g., holes in closures
  due to disk corruption).
 2005-12-23 21:36:44 +00:00
Eelco Dolstra 4b9e7f59ca * Revived the old "nix-store --delete" operation that deletes the 
specified paths from the Nix store.  However, this operation is
  safe: it refuses to delete anything that the garbage collector
  wouldn't delete.
 2005-12-23 21:08:42 +00:00
Eelco Dolstra 530b27df1e * `nix-store --gc' prints out the number of bytes freed on stdout 
(even when it is interrupted by a signal).
 2005-12-15 21:11:39 +00:00
Eelco Dolstra b1eed6b586 * Split the database upgrade into multiple transactions to prevent 
Berkeley DB from running out of locks.
 2005-12-15 16:53:21 +00:00
Eelco Dolstra ab5c6bb3a3 * Change referer' to referrer' throughout. In particular, the 
nix-store query options `--referer' and `--referer-closure' have
  been changed to `--referrer' and `--referrer-closure' (but the old
  ones are still accepted for compatibility).
 2005-12-13 21:04:48 +00:00
Eelco Dolstra d87549c1c7 * Automatically delete the old referers table. 2005-12-12 19:14:38 +00:00
Eelco Dolstra 8463f27d8c * Fix NIX-23: quadratic complexity in maintaining the referers 
mapping.  The referer table is replaced by a referrer table (note
  spelling fix) that stores each referrer separately.  That is,
  instead of having

    referer[P] = {Q_1, Q_2, Q_3, ...}

  we store

    referer[(P, Q_1)] = ""
    referer[(P, Q_2)] = ""
    referer[(P, Q_3)] = ""
    ...

  To find the referrers of P, we enumerate over the keys with a value
  lexicographically greater than P.  This requires the referrer table
  to be stored as a B-Tree rather than a hash table.

  (The tuples (P, Q) are stored as P + null-byte + Q.)

  Old Nix databases are upgraded automatically to the new schema.
 2005-12-12 18:24:42 +00:00
Eelco Dolstra a33b561a6b * Use Berkeley DB 4.4's process registry feature to recover from 
crashed Nix instances, and toss out our own recovery code.
 2005-12-09 22:55:07 +00:00
Eelco Dolstra 760264bffe * Require Berkeley DB 4.4. 
* Checkpoint after an upgrade.
 2005-12-06 15:00:04 +00:00
Eelco Dolstra b7f008fc35 * Did something useful while waiting at IAD: reference scanning is now 
much faster.
 2005-11-16 08:27:06 +00:00
Eelco Dolstra 9311ab76a5 * Install signal handlers for SIGTERM and SIGHUP. This ensures that 
Nix is properly shut down when it receives those signals.  In
  particular this ensures that killing the garbage collector doesn't
  cause a subsequent database recovery.
 2005-11-04 15:34:09 +00:00
Eelco Dolstra 5bf939885a * Memoise checkVarDefs since internally produced terms (i.e., not the 
result of parsing) can have very heavy sharing, causing exponential
  complexity if we naively recurse into them.  ATerms are graphs, not
  trees!
 2005-11-04 15:17:05 +00:00
Eelco Dolstra 221c79013f * Turn off build hooks in nix-push because of an impurity (NIX-21). 2005-10-29 18:17:45 +00:00
Rob Vermaas f0856fd905 * Repair the referers table from the references table. 2005-10-29 15:44:02 +00:00
Eelco Dolstra 92d599c6a7 * Prevent uids from being used for more than one build 
simultaneously.  We do this using exclusive locks on uid files in
  /nix/var/nix/userpool, e.g., /nix/var/nix/userpool/123 for uid 123.
 2005-10-20 16:58:34 +00:00
Eelco Dolstra e932c40f8e * Oops. Fixed-output derivations were broken. 2005-10-19 14:27:44 +00:00
Eelco Dolstra 13b089c890 * Also kill all processes of the build user after the build. This is 
critical to prevent certain kinds of 0wnage.
 2005-10-17 17:43:21 +00:00
Eelco Dolstra f1b3a418fa * Before starting a build under some uid, kill all current processes 
running under that uid.
 2005-10-17 17:35:37 +00:00
Eelco Dolstra 439823ae80 * Check that the build result is owned by the build user, and that 
nobody else has write permission to the build result.  This catches
  most hack attempts.
 2005-10-17 16:59:25 +00:00
