Eelco Dolstra 04cf72287b * This may be useful in the future. 2006-05-31 09:24:54 +00:00
Eelco Dolstra 1390ce4142 * Not all platforms have sys/select.h. 2006-05-30 11:37:21 +00:00
Eelco Dolstra b1c63dc362 * Don't use badTerm, it gives awful error messages. 2006-05-30 11:31:33 +00:00
Eelco Dolstra c7d9397fc9 * Handle $PATHs with spaces. 2006-05-29 21:53:58 +00:00
Eelco Dolstra 58b4198ed8 * Disable the concurrent garbage collector on Cygwin for now. 2006-05-29 20:46:51 +00:00
Eelco Dolstra d764409d97 * Some Cygwin fixes. 2006-05-24 13:23:20 +00:00
Eelco Dolstra b5988004d6 * Support for srcdir != builddir (NIX-41). 2006-05-12 11:47:45 +00:00
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.
 2006-05-11 02:19:43 +00:00
Eelco Dolstra e3c07782d1 * Remove old manifests in `nix-channel --update'. 2006-05-08 20:00:28 +00:00
Eelco Dolstra c54287eafe * GCC 2.95 compatibility. 2006-05-08 15:15:13 +00:00
Eelco Dolstra 8b5aa91aa7 2006-05-08 14:00:39 +00:00
Eelco Dolstra 5cabd47394 * Allow function argument default values to refer to other arguments 
of the function.  Implements NIX-45.
 2006-05-08 12:52:47 +00:00
Eelco Dolstra 310e605995 * Show evaluation stats when NIX_SHOW_STATS=1. 2006-05-08 10:00:37 +00:00
Eelco Dolstra 0832956089 * Use the new ATermMap. 2006-05-04 12:21:08 +00:00
Eelco Dolstra 9840368cad * Iterators. 2006-05-04 09:22:29 +00:00
Eelco Dolstra 6980544467 * Keep some statistics about memory allocation. 2006-05-04 08:32:30 +00:00
Eelco Dolstra b803fb95cb * Maintain the count field properly. 2006-05-03 23:17:42 +00:00
Eelco Dolstra db0d865ec4 * New ATermMap, seems more-or-less finished. 2006-05-03 23:07:38 +00:00
Eelco Dolstra 052cefe1bd * Started hacking on a ATermTable replacement, since ATermTable uses 
gigantic amounts of memory --- 65536 bytes per table at least ---
  which makes it unsuitable for representing short-lived substitution
  tables and attribute sets.
 2006-05-03 17:29:48 +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
Eelco Dolstra 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 ae55e79541 * More tests. 2006-05-02 11:20:55 +00:00
Eelco Dolstra dca43ef795 * Tests for NIX-45. 2006-05-02 11:15:04 +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 cce31b739c * svn:ignore 2006-04-29 11:54:45 +00:00
Eelco Dolstra 6fca1b82ae * Change this to LGPL to keep the government happy. 2006-04-25 16:41:06 +00:00
Eelco Dolstra de8f2d061c * Install only the header file and libraries from Berkeley DB. 2006-04-25 11:52:24 +00:00
Eelco Dolstra e18c93169c * Create libexec. 2006-04-25 11:33:27 +00:00
Eelco Dolstra 0748331b70 * Typo. 2006-04-25 10:57:08 +00:00
Eelco Dolstra 03162f8f47 * Unless --with-bzip2 is specified, use a copy of bzip2 in the 
externals directory.  This is in particular useful because though
  most systems have bzip2/bunzip2, they don't always have libbz2,
  which we need for bsdiff/bspatch.
 2006-04-25 10:45:53 +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 20675feeab * Update copyright. 2006-03-15 12:58:22 +00:00
Eelco Dolstra 05bb644890 * Allow the resulting symlink of nix-build to be named, e.g., 
$ nix-build .../i686-linux.nix -A apacheHttpd -o apache
 2006-03-14 16:35:01 +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 a33fb2d287 * Oops. 2006-03-10 16:14:30 +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
Eelco Dolstra 9811815429 * Write messages to stderr, not stdout. 2006-03-10 09:41:28 +00:00
Eelco Dolstra 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.
