70dee0f8ca * Flags --to-base32' and --to-base16' to convert between hex and
base-32 hashes.

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 ;-)

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'

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.

Eelco Dolstra
889ef564fd * Fix the infamous NIX-17: nix-env -i prints misleading messages
("installing `foo'" followed by "uninstalling `foo'").

345a95afe9 * Allow the size of the GC reserved file to be specified in nix.conf
through the new `gc-reserved-space' option.

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.

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.

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.

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!

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.

4eb637c799 * When querying all derivations, filter out syntactically equal derivations. 2006-02-08 16:15:07 +00:00

8688e83194 * When evaluating, automatically call functions with default arguments. 2006-02-08 15:22:30 +00:00

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.)

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.

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

1029716a8a * Don't show cycles, they're not very useful. 2006-01-19 15:35:34 +00:00

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
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).

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.

530b27df1e * `nix-store --gc' prints out the number of bytes freed on stdout
(even when it is interrupted by a signal).

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).

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.

a33b561a6b * Use Berkeley DB 4.4's process registry feature to recover from
crashed Nix instances, and toss out our own recovery code.

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!

221c79013f * Turn off build hooks in nix-push because of an impurity (NIX-21). 2005-10-29 18:17:45 +00:00
