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.

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.

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.
