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.

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.)

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.

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

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.

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 3c5619c7e4 * Begin release notes. 2005-12-15 21:11:55 +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 5144f750c4 * Typo. 2005-12-15 17:04:02 +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 11a8dc76d6 * Doh! 2005-12-15 13:45:10 +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 18bbcb1214 * Add a test to demonstrate the quadratic complexity of referrer
(de)registration, in particular garbage collection (NIX-23).
2005-12-11 19:25:48 +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 eb268a7f95 * Apply the patch. 2005-12-08 22:14:15 +00:00
Eelco Dolstra dfffd92568 * A patch to make the DB_REGISTER feature work when debug info is not on. 2005-12-08 18:18:20 +00:00
Eelco Dolstra 760264bffe * Require Berkeley DB 4.4.
* Checkpoint after an upgrade.
2005-12-06 15:00:04 +00:00
Eelco Dolstra dc528128cc * FreeBSD compatibility fix. 2005-11-17 13:58:23 +00:00
Eelco Dolstra 44409f52c1 * "Fix" the test, since we cannot feasibly support the intended semantics. 2005-11-17 11:58:22 +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 1f285cf556 * Scoping bug in `with'. 2005-11-04 14:50:33 +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
