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 f316b6c1a9 * Manual updates (especially how nix-build makes testing packages much 
easier; no longer need a helper expression).
 2006-10-02 11:50:55 +00:00
Eelco Dolstra 91a01e6fcf * Manual. 2006-10-02 09:01:36 +00:00
Eelco Dolstra 88d422567e * One-click installs. 2006-09-29 14:59:10 +00:00
Eelco Dolstra 0212feeed6 * Document nix-install-package and the nixpkg file format. 2006-09-29 14:16:41 +00:00
Eelco Dolstra 070e07ed5a * Manual. 2006-09-29 11:03:16 +00:00
Eelco Dolstra 30c7db85d8 * Manual updates, some style improvements. 2006-09-29 10:31:56 +00:00
Eelco Dolstra e2eed05224 * Manual updates. 
* Documented nix-{pack,unpack}-closure.
 2006-09-28 09:10:53 +00:00
Eelco Dolstra 4ad6fb7ea3 * Fix setuid builds. 2006-09-27 21:04:07 +00:00
Eelco Dolstra 015ac7c7da * Release notes. 2006-09-27 13:27:26 +00:00
Eelco Dolstra a9a6356ffc * Release notes. 2006-09-27 12:43:00 +00:00
Eelco Dolstra e47d42536f * Release notes. 2006-09-26 09:57:27 +00:00
Eelco Dolstra 5ca45d085e * Use "propagated-user-env-packages", not "propagated-build-inputs" 
for packages that should be propagated to the user environment.
 2006-09-25 15:11:59 +00:00
Eelco Dolstra 02f2335712 * Propagated packages now have lower priority; they are symlinked 
*after* the packages that have been explicitly installed, and
  collisions are ignored.
 2006-09-25 15:07:45 +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 d43565c3e8 * In `nix-channel --update', skip manifests that assume a Nix store at 
a different location than the user's.  This makes channels usable as
  a source deployment mechanism for people who install Nix under
  non-standard prefixes.  (NIX-57)
 2006-09-25 11:11:16 +00:00
Eelco Dolstra 68ae953d8a * Clean up calls to system(). 2006-09-25 10:44:27 +00:00
Eelco Dolstra 76c9710091 * Use builtins.toPath. 2006-09-25 10:29:25 +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 385c6f8737 * Supply the 64-bit ATerm patch, but don't apply it (since that 
requires rerunning Autoconf/Automake).  Interested users should do
  that themselves.
 2006-09-22 12:07:41 +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 4cab35d1a6 * Build with -D_FILE_OFFSET_BITS=64 to support files >= 2^31 bytes 
(NIX-22).
 2006-09-22 11:13:12 +00:00
Eelco Dolstra 25df501704 * GC options in nix-store --help (NIX-15). 2006-09-21 19:06:34 +00:00
Eelco Dolstra 0bd5eb71a0 * `nix-install-package --url': install from a URL (NIX-12). 
* `nix-install-package --help' (NIX-9).
* `nix-install-package --non-interactive': don't prompt or pause.
* Tests for nix-install-package.
* Security fixes: filter the values obtained from the nixpkg.
 2006-09-21 18:54:08 +00:00
Eelco Dolstra 4e91d8621f * Fix comment. 2006-09-21 18:52:05 +00:00
Eelco Dolstra ee5040421f * Try konsole and gnome-terminal in addition to xterm. 2006-09-21 11:29:14 +00:00
Eelco Dolstra 1bdc152931 * Shut up a warning. 2006-09-20 16:36:29 +00:00
Eelco Dolstra 1b804f88e4 * Absolute path to rm (NIX-51). 
* Don't hardcore /nix/bin and /nix/store.
 2006-09-20 16:23:14 +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 22d13d6ec2 * Check for patch (NIX-59). 2006-09-20 15:28:47 +00:00
Eelco Dolstra 947e645789 * Hide warnings about a missing "lsof" (NIX-54). 2006-09-20 15:14:19 +00:00
Eelco Dolstra a060adf165 * Use paths, not strings, when calling the function that generates 
NARs.  Fixes the impurity of nix-push (NIX-21).
* Better help.
 2006-09-20 15:04:04 +00:00
Eelco Dolstra 7dd342e482 * Doh. 2006-09-19 16:40:22 +00:00
Eelco Dolstra ee6cf99660 * Doh! Of course we have to take execute permission into account. 
* Restore the mtime on modified directories.
 2006-09-19 16:14:15 +00:00
Eelco Dolstra 6dbed1bf38 * `optimise-store.pl' reduces disk space consumption by hard-linking 
all identitical files in the Nix store to each other.  (Previously
  it only computed the size that would be saved by doing so.)
 2006-09-19 14:58:35 +00:00
Eelco Dolstra 07cec27848 * Cleanups. 2006-09-19 14:27:28 +00:00
Eelco Dolstra 9488ae7357 * `show-duplication.pl', a small utility that shows the amount of 
package duplication present in (e.g.) a profile.  It shows the
  number of instances of each package in a closure, along with the
  size in bytes of each instance as well as the "waste" (the
  difference between the sum of the sizes of all instances and the
  average size).

  $ ./show-duplication.pl /nix/var/nix/profiles/default
  gcc 11
    3.3.6 19293318
    3.4.4 21425257
    ...
    average 14942970, waste 149429707
  coreutils 6
  ...
  average package duplication 1.87628865979381, total size 3486330471, total waste 1335324237, 38.3017114443825% wasted

  This utility is useful for measuring the cost in terms of disk space
  of the Nix approach.
 2006-09-19 13:53:35 +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.
