6846ed8b44 * Make --cores work when building through the Nix daemon. 2010-08-12 09:21:50 +00:00

fd9c77dfc7 * Use SQLite 3.7.0's write-ahead logging (WAL mode). This is a lot 
faster than the old mode when fsyncs are enabled, because it only
  performs an fsync() when doing a checkpoint, rather than at every
  commit.  Some timings for doing a "nix-instantiate /etc/nixos/nixos
  -A system" after modifying the stdenv setup script:

    42.5s - SQLite 3.6.23 with truncate mode and fsync
     3.4s - SQLite 3.6.23 with truncate mode and no fsync
    32.1s - SQLite 3.7.0 with truncate mode and fsync
    16.8s - SQLite 3.7.0 with WAL mode and fsync, auto-checkpoint
            every 1000 pages
     8.3s - SQLite 3.7.0 with WAL mode and fsync, auto-checkpoint
            every 8192 pages
     1.7s - SQLite 3.7.0 with WAL mode and no fsync

  The default is now to use WAL mode with fsyncs.  Because WAL doesn't
  work on remote filesystems such as NFS (as it uses shared memory),
  truncate mode can be re-enabled by setting the "use-sqlite-wal"
  option to false.

750be19ae8 * Remove "auto" and "guess" as synonyms for 0 in the handling of 
build-cores and --cores.  They're superfluous and just complicate
  the parsing.

7f893b7a43 * Allow derivations to hint that they should not be built remotely 
using the build hook mechanism, by setting the derivation attribute
  "preferLocalBuild" to true.  This has a few use cases:

  - The user environment builder.  Since it just creates a bunch of
    symlinks without much computation, there is no reason to do it
    remotely.  In fact, doing it remotely requires the entire closure
    of the user environment to be copied to the remote machine, which
    is extremely wasteful.

  - `fetchurl'.  Performing the download on a remote machine and then
    copying it to the local machine involves twice as much network
    traffic as performing the download locally, and doesn't save any
    CPU cycles on the local machine.

315d8fbd75 * Set the default system filter to "*". This ensures that (for 
instance) "nix-env -i wine" works on x86_64-linux, even though Wine
  is built on i686-linux.  In the event that there are multiple
  matching derivations, prefer those built for the current system.

6d6200f37a * Optimisation in the // operator: if one of the sets is empty, return 
the other set.

Eelco Dolstra
7af6a2fd71 * intersectAttrs: optimise for the case where the second set is larger 
than the first set.  (That's usually the case with callPackage.)

bcec46057c src/libutil/util.cc: include <limit.h> to ensure that PATH_MAX is defined 2010-06-24 17:51:13 +00:00

a17071fef1 Include <cstring> to ensure that strcpy(), strlen(), and memset() are declared. 
An "using namespace std" was added locally in those functions that refer to
names from <cstring>. That is not pretty, but it's a very portable solution,
because strcpy() and friends will be found in both the 'std' and in the global
namespace.

8b7f8b56f1 Added support for passing an (impure) NIX_BUILD_CORES variable to build expressions. 
This patch adds the configuration file variable "build-cores" and the
command line argument "--cores". These settings specify the number of
CPU cores to utilize for parallel building within a job, i.e. by passing
an appropriate "-j" flag to GNU Make. The default value is 1, which
means that parallel building is *disabled*. If the number of build cores
is specified as 0 (synonymously: "guess" or "auto"), then the actual
value is supposed to be auto-detected by builders at run-time, i.e by
calling the nproc(1) utility from coreutils.

The environment variable $NIX_BUILD_CORES is available to builders, but
the contents of that variable does *not* influence the hash that goes
into the $out store path, i.e. the number of build cores to be utilized
can be changed at will without requiring any re-builds.

3e5e0faf9c * Okay, putting a lock on the temporary directory used by importPath() 
doesn't work because the garbage collector doesn't actually look at
  locks.  So r22253 was stupid.  Use addTempRoot() instead.  Also,
  locking the temporary directory in exportPath() was silly because it
  isn't even in the store.

f16fe2af8d * builtins.toXML: propagate the string context. This is a regression

d1f6c0cbe3 * Replacing ValidPath rows doesn't work because it causes a constraint 
violation of the Refs table.  So don't do that.

ebade9ff8b * Check for duplicate attribute names / function arguments. `make 
check' now succeeds :-)
* An attribute set such as `{ foo = { enable = true; };
  foo.port = 23; }' now parses.  It was previously rejected, but I'm
  too lazy to implement the check.  (The only reason to reject it is
  that the reverse, `{ foo.port = 23; foo = { enable = true; }; }', is
  rejected, which is kind of ugly.)

6bbfe95e30 * Don't use an ostringstream in unparseDerivation(), because it's 
slow.  A `nix-env -qa --drv-path \*' on Nixpkgs was spending 40% of

  variable.)
 2010-04-16 13:44:02 +00:00
Eelco Dolstra
04c4bd3624 * Store lists as lists of pointers to values rather than as lists of

Eelco Dolstra
9985230c00 * After parsing, compute level/displacement pairs for each variable 
use site, allowing environments to be stores as vectors of values

Eelco Dolstra
85d13c8f93 * Change the semantics of "with" so that inner "withs" take 
precedence, i.e. `with {x=1;}; with {x=2;}; x' evaluates to 2'.
  This has a simpler implementation and seems more natural.  There
  doesn't seem to be any code in Nixpkgs or NixOS that relies on the
  old behaviour.
 2010-04-14 08:37:08 +00:00
Eelco Dolstra
816f9c0f6f * Use std::tr1::unordered_set instead of std::set for the symbol 
table.  This gives a 10% speed increase on `nix-instantiate

 2010-04-13 14:34:11 +00:00
Eelco Dolstra
7d47498b5e * Evaluate lets directly (i.e. without desugaring to `rec { attrs...;

 2010-04-13 13:42:25 +00:00
Eelco Dolstra
ac1e8f40d4 * Use a symbol table to represent identifiers and attribute names 
efficiently.  The symbol table ensures that there is only one copy

  using a pointer equality test.

c172274e17 * Quick hack to make coerceToString work more or less correctly on 
nested lists.  `nix-instantiate' can now evaluate the NixOS system

71f026292b * Make `derivation' lazy again for performance. It also turns out 
that there are some places in Nixpkgs (php_configurable /
  composableDerivation, it seems) that call `derivation' with
  incorrect arguments (namely, the `name' attribute missing) but get
  away with it because of laziness.

dc31305b38 * Fixed the trace primop and path comparison. 
* Removed exprToString and stringToExpr because there is no ATerm

  evaluator like this is not a good idea anyway).
 2010-03-31 20:09:20 +00:00
Eelco Dolstra

09381cccff Make source location info in the XML output optional.

Ludovic Courtès
471419d1fa Add source location information to the XML output. 
* src/libexpr/expr-to-xml.cc (nix::showAttrs): Dereference the attribute
  RHS.  Add "path", "line", and "column" XML attributes to the node when
  source location information is available.
  (nix::printTermAsXML): Likewise for functions.

Eelco Dolstra
cad8726b2c * Implemented the ==' and !=' operators. These now use a deep 
equality test, so they also work for (finite) attribute sets and
  lists.

Eelco Dolstra
25eedf085d * Quick and dirty implementation of with'. with e1; e2' is 
basically desugared to `let <with> = e1; e2', and `lookupVar' looks
  in each <with> in the environment chain for an attribute with the
  specified name.

Eelco Dolstra
8a10360c91 * Simplify @-patterns: only {attrs}@name' or name@{attrs}' are now 
allowed.  So `name1@name2', `{attrs1}@{attrs2}' and so on are now no
  longer legal.  This is no big loss because they were not useful
  anyway.

  This also changes the output of builtins.toXML for @-patterns
  slightly.
 2010-03-25 12:19:41 +00:00

responsibility for allocation of the result to the caller.

Eelco Dolstra
4c356acd04 * In `nix-store --export', abort if the contents of a path has 
changed.  This prevents corrupt paths from spreading to other
  machines.  Note that checking the hash is cheap because we're
  hashing anyway (because of the --sign feature).
 2010-03-09 14:32:03 +00:00

collection happens during fixAttrs().
 2010-03-02 20:23:42 +00:00
Eelco Dolstra
56af8e86e3 * Protect the true', false' and `__overrides' constants. Without 
an ATprotect call, these could be garbage collected, leading to
  weird crashes or wrong results.
 2010-03-02 20:09:12 +00:00
Eelco Dolstra
3f9e647ae8 * checkInterrupt() shouldn't be called from a destructor. 2010-03-02 19:04:17 +00:00
Eelco Dolstra
594eaddd11 * When using the included sqlite/aterm libraries, build with 
--enable-shared.
* In libutil/libstore/libexpr etc., link against sqlite and aterm.
* Some more header file hygiene.
 2010-03-02 15:58:13 +00:00

Eelco Dolstra
84a4dd5ff0 * Don't use fdatasync since it doesn't work on Snow Leopard. 
* Don't refer to config.h in util.hh, because config.h is not
  installed (http://hydra.nixos.org/build/303053).
 2010-02-24 15:46:06 +00:00

9fd85c94de * Use `truncate' journal mode, which should be a bit faster. 2010-02-24 14:22:34 +00:00
Eelco Dolstra
fefd467539 * `helpText' is now zero-terminated. 2010-02-24 13:24:27 +00:00
Eelco Dolstra
a3c63d0d6c * Disable fsync() in SQLite if the fsync-metadata option is set to 
false.
* Change the default for `fsync-metadata' to true.
* Disable `fsync-metadata' in `make check'.
 2010-02-24 13:12:57 +00:00
Eelco Dolstra
90b6352d0a * Do registerValidPaths() in one transaction, which is much faster. 
E.g. it cuts the runtime of the referrers test from 50s to 23s.
 2010-02-24 12:48:00 +00:00
Eelco Dolstra
fae0427324 * ADDITIONAL_NETWORK_LIBS -> LIBS. 2010-02-24 12:25:48 +00:00
Eelco Dolstra
fa6a4fcb11 * Add ${sqlite_lib} everywhere. Just adding it in `libstore' doesn't 
work on x86_64 when sqlite is compiled statically.
 2010-02-24 12:18:48 +00:00
Eelco Dolstra
5954eadf67 * Remove the fdatasync check since it's no longer needed. 2010-02-24 12:16:50 +00:00
Eelco Dolstra
462bd50aef * Use normal (rather than full) synchronous mode, which I gather from 
the description at http://www.sqlite.org/atomiccommit.html should be
  safe enough.

Eelco Dolstra
9cda616949 * The database needs a trigger to get rid of self-references to 
prevent a foreign key constraint violation on the Refs table when
  deleting a path.
 2010-02-22 14:18:55 +00:00
Eelco Dolstra
c4d388add4 * Get derivation outputs from the database instead of the .drv file, 
which requires more I/O.
 2010-02-22 12:44:36 +00:00
Eelco Dolstra
103cfee056 * Revert r19650 (implement gc-keep-outputs by looking for derivations 
with the same name as the output) and instead use the
  DerivationOutputs table in the database, which is the correct way to
  to do things.
 2010-02-22 11:44:17 +00:00
Eelco Dolstra
299ff64812 * Put the derivation outputs in the database. This is useful for the 
garbage collector.
 2010-02-22 11:15:50 +00:00
Eelco Dolstra
1930570ad9 * Foreign key support in SQLite is not a persistent setting, so enable 
it at startup.
* Implement negative caching.  Now `make check' passes.
 2010-02-19 17:15:22 +00:00

cfb09e0fad * Automatically abort transactions if they go out of scope without 
committing.
 2010-02-18 14:40:07 +00:00
Eelco Dolstra
e0305bb7a8 * Some wrapper objects to ensure that SQLite objects are properly 
destroyed.
 2010-02-18 14:30:42 +00:00
Eelco Dolstra
a053d2d8e5 * Add the deriver to the ValidPaths table. In principle we could now 
store all the derivers of a path efficiently.  But that opens a big
  can of worms with respect to garbage collector semantics.
 2010-02-18 13:48:18 +00:00
Eelco Dolstra
dbddac0fe9 * Assign an integer id to every row in the ValidPaths table in order 
to make the Refs table more space-efficient.  For instance, this
  reduces the size of the database on my laptop from 93 MiB to 18
  MiB.  (It was 72 MiB with the old schema on an ext3 disk with a 1
  KiB block size.)
 2010-02-18 13:40:46 +00:00
Eelco Dolstra
c1a07f9445 * Convert the Nix database to SQLite. 2010-02-18 13:16:59 +00:00
Ludovic Courtès
20186a4079 Don't rely on `PATH_MAX' on GNU. 2010-02-10 15:55:50 +00:00
Eelco Dolstra
4e17be7981 * Revert r19797, and use a simpler solution: just don't monitor build 
hooks for silence.  It's unnecessary because the remote nix-store
  command is already monitoring the real build.
 2010-02-03 21:38:41 +00:00
Eelco Dolstra
f859a8d3c3 * While waiting for a lock, print a sign of life every 5 minutes. 
This prevents remote builders from being killed by the
  `max-silent-time' inactivity monitor while they are waiting for a
  long garbage collection to finish.  This happens fairly often in the
  Hydra build farm.
 2010-02-03 21:22:57 +00:00
Eelco Dolstra
4bbbe25802 * Remove most Cygwin-specific code. Cygwin 1.7 implements advisory 
POSIX locks, and simulates Unix-style file deletion semantics
  sufficiently.  Note that this means that Nix won't work on Cygwin
  1.5 anymore.
 2010-02-02 15:28:36 +00:00
Eelco Dolstra
2723d9b56e * If fdatasync() isn't available, use fsync(). 2010-02-02 11:57:49 +00:00
Eelco Dolstra
07ffdc2862 * Added an option "fsync-metadata" to fsync() changes to 
/nix/var/nix/db.
* Removed the function writeStringToFile since it does (almost) the
  same thing as writeFile.
 2010-01-29 12:22:58 +00:00
Eelco Dolstra
ad529fb89f * Don't consider a store path valid if its info file exists but is 
zero bytes long.  That makes Nix more robust in case of crashes
  (especially on ext4).
 2010-01-29 11:53:58 +00:00
Eelco Dolstra
fdcaf37361 * Made `nix-store -qR --include-outputs' much faster if there are 
multiple paths specified on the command line (from O(n * m) to O(n +
  m), where n is the number of arguments and m is the size of the
  closure).
 2010-01-25 17:18:44 +00:00
Eelco Dolstra
5388944e8d * Make the garbage collector do the right thing when `gc-keep-outputs' 
is enabled by not depending on the deriver.
 2010-01-25 16:04:32 +00:00
Eelco Dolstra
f0c0277970 * On startup, set the default SIGCHLD handler. This is so that Nix 
works correctly in weird environments where the SIGCHLD handler is
  set to "ignore".
 2010-01-12 12:22:38 +00:00
