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.

57751fdb55 * Refactoring to support domain checks. 2006-07-24 15:16:03 +00:00

Eelco Dolstra
c15f544356 * Call find-runtime-roots.pl from the garbage collector to prevent
running applications etc. from being garbage collected.

d51aede4af * Allow the canonical system name to be specified at runtime in the
Nix config file.

a945fb7905 * `nix-env --upgrade --eq': only upgrade if the old version is equal
to the new version.  This is actually useful.

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

0e783e5579 * Write messages to stderr in a slightly more atomic way. Useful when
there are several parallel processes.

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.

b454977909 * Fix for a problem with BSD's group ownership semantics when the user
is not in the "wheel" group.

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.

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

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

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.
2006-03-09 15:09:18 +00:00
Eelco Dolstra
6dca5c9099 * When obtaining derivations from Nix expressions, ignore all
expressions that cause an assertion failure (like `assert system ==
  "i686-linux"').  This allows all-packages.nix in Nixpkgs to be used
  on all platforms, even if some Nix expressions don't work on all
  platforms.

  Not sure if this is a good idea; it's a bit hacky.  In particular,
  due to laziness some derivations might appear in `nix-env -qa' but
  disappear in `nix-env -qas' or `nix-env -i'.

c8bfb11b34 * `nix-env (-i|-u) --dry-run' now shows exactly which missing paths

Eelco Dolstra
70dee0f8ca * Flags --to-base32' and --to-base16' to convert between hex and
base-32 hashes.
2006-03-01 18:05:47 +00:00
Eelco Dolstra
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 ;-)

74166f2f44 * db.hh shouldn't depend on the Berkeley DB headers. 2006-03-01 17:44:28 +00:00

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
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.
2006-02-16 13:19:15 +00:00
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
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.

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.)
2006-02-02 16:27:31 +00:00
Eelco Dolstra
6e2eaaec96 * Print a better error message when writing the patched file (e.g.,

04be39734f * Resolve all symlink components in the location of the temporary

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
530b27df1e * `nix-store --gc' prints out the number of bytes freed on stdout

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