Eelco Dolstra f0d6318dd1 * More tests. 2006-02-22 14:02:44 +00:00
Eelco Dolstra ddb78dfc3d * Check whether "nix-store -q --graph" generates a valid dot graph.
* Test "nix-store -q --tree" as well.

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 58fc420b36 * And another test. 2006-02-17 17:05:34 +00:00
Eelco Dolstra 4ddd5ff39c * Regression test for NIX-31. 2006-02-17 17:03:19 +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.

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 0ca0a4da9f * Valgrind suppressions for the ATerm library. The ATerm library uses
a conservative garbage collector that scans the stack and parts of
  the heap for pointers to ATerms.  This scan can touch uninitialised
  memory, which is harmless.  Use:

  $ valgrind --suppressions=aterm-gc.supp ...

Eelco Dolstra da0a6b6499 * Doh. 2006-02-12 21:00:36 +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 b505f9eaf5 * Document that nix-instantiate can read from stdin. 2006-02-10 15:29:17 +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 f8aadf14c3 * Test-driven development, woohoo! nix-env should work on functions,
provided that all arguments have defaults.
2006-02-08 15:21:57 +00:00
Eelco Dolstra 287d0ef41c * Oops, fix breakage. 2006-02-08 14:32:33 +00:00
Eelco Dolstra e771e59178 * Tests for nix-env, finally! 2006-02-08 14:32:06 +00:00
Eelco Dolstra 39f50db731 * Refactoring: move derivation evaluation to libexpr. 2006-02-08 13:21:16 +00:00
Eelco Dolstra 4db4b61380 * Don't install nix.conf (so it won't be overriden when you upgrade an RPM). 2006-02-07 14:47:26 +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 d9d6ff9f8e * Doh. 2006-02-01 16:49:52 +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 3eba483692 * Use Berkeley DB 4.4.20. 2006-02-01 14:52:58 +00:00
Eelco Dolstra 151f10dbc7 * Add @bindir@. 2006-02-01 12:41:54 +00:00
Eelco Dolstra 83424eb71b * Don't force a build of derivations. 2006-01-26 23:18:46 +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 e4d4969ae9 * New tools nix-pack-closure and nix-unpack-closure. These provide a
useful way to transfer the closure of a store path to another
  machine.

  These commands provide functionality previously possible through
  `nix-push --copy'.  However, they are much more convenient in many
  situations (though possibly less efficient).
  
  Example:
  $ nix-pack-closure /nix/store/hj232g1r...-subversion-1.3.0 > svn.closure
  (on another machine:)
  $ nix-unpack-closure < svn.closure

  Note that Subversion is added to the store, but not installed into a
  user environment.  One should do `nix-env -i
  /nix/store/hj232g1r...-subversion-1.3.0' for that.

  Another example: copy the application Azureus to the machine
  `scratchy' through ssh:
  
  $ nix-pack-closure $(which azureus) | ssh scratchy nix-unpack-closure
2006-01-12 15:17:51 +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.
