Eelco Dolstra d7efd76394 * Big cleanup of the semantics of paths, strings, contexts, string 
concatenation and string coercion.  This was a big mess (see
  e.g. NIX-67).  Contexts are now folded into strings, so that they
  don't cause evaluation errors when they're not expected.  The
  semantics of paths has been clarified (see nixexpr-ast.def).
  toString() and coerceToString() have been merged.

  Semantic change: paths are now copied to the store when they're in a
  concatenation (and in most other situations - that's the
  formalisation of the meaning of a path).  So

    "foo " + ./bla

  evaluates to "foo /nix/store/hash...-bla", not "foo
  /path/to/current-dir/bla".  This prevents accidental impurities, and
  is more consistent with the treatment of derivation outputs, e.g.,
  `"foo " + bla' where `bla' is a derivation.  (Here `bla' would be
  replaced by the output path of `bla'.)

* Indent XML output.
 2006-08-16 10:32:30 +00:00

automated processing.
 2006-08-03 15:52:09 +00:00
Eelco Dolstra 0e267e2625 * `nix-instantiate --print-args': produce XML output so that the 
result can be used more easily by scripts.
 2006-08-03 14:49:57 +00:00
Eelco Dolstra 4750f6c5ed * Simple class for writing XML files. 2006-08-03 13:21:21 +00:00
Eelco Dolstra c15f544356 * Call find-runtime-roots.pl from the garbage collector to prevent 
running applications etc. from being garbage collected.
 2006-07-20 12:17:25 +00:00
Eelco Dolstra d51aede4af * Allow the canonical system name to be specified at runtime in the 
Nix config file.
 2006-07-06 15:30:37 +00:00
Eelco Dolstra 0e783e5579 * Write messages to stderr in a slightly more atomic way. Useful when 
there are several parallel processes.
 2006-06-19 14:37:35 +00:00
Eelco Dolstra b454977909 * Fix for a problem with BSD's group ownership semantics when the user 
is not in the "wheel" group.
 2006-06-14 11:53:55 +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 c54287eafe * GCC 2.95 compatibility. 2006-05-08 15:15:13 +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 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 9088dee9e2 * Some refactoring of the exception handling code so that we can catch 
Nix expression assertion failures.
 2006-03-08 14:11:19 +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 ;-)
 2006-03-01 17:59:08 +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 8291f6d968 * bsdiff updated to 4.3. This makes Nix depend on libbz2. 2006-02-01 16:48:49 +00:00
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.
 2006-01-08 17:16:03 +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 b7f008fc35 * Did something useful while waiting at IAD: reference scanning is now 
much faster.
 2005-11-16 08:27:06 +00:00
Eelco Dolstra 4578a490ce * Parse multi-valued options. 2005-09-22 15:43:22 +00:00
Eelco Dolstra 4c20a08293 * Build dynamic libraries. 2005-07-22 14:52:45 +00:00
Eelco Dolstra 26fd28432d * FreeBSD 4.x doesn't have stdint.h, use inttypes.h instead (which is 
also part of ISO C).
 2005-05-04 16:32:54 +00:00
Eelco Dolstra ae6d9033a1 * The eof() state isn't guaranteed to be set non-lazily. GCC 2.95 
compatibility fix.
 2005-05-04 16:29:44 +00:00
Eelco Dolstra c6178f0b03 * Create missing log and temproots directories automatically (reported 
by Rob).
 2005-03-24 17:46:38 +00:00
Eelco Dolstra cff6bc06df * Fix endianness bug. 2005-03-23 19:18:22 +00:00
Eelco Dolstra 4bbdcfbb45 * Don't use fork() in copyPath(), but a string buffer. 2005-03-03 13:58:02 +00:00
Eelco Dolstra 20ce2642fc * Refactoring to support different installation sources in nix-env. 
* Set the references for the user environment manifest properly.
* Don't copy the manifest (this was accidental).
* Don't store derivation paths in the manifest (maybe this should be
  made optional).  This cleans up the semantics of nix-env, which were
  weird.
* Hash on the output paths of activated components, not on derivation
  paths.  This is because we don't know the derivation path of already
  installed components anymore, and it allows the installation of
  components by store path (skipping Nix expressions entirely).
* Query options `--out-path' and `--drv-path' to show the output and
  derivation paths of components, respectively (the latter replaces
  the `--expr' query).
 2005-02-11 16:56:45 +00:00
Eelco Dolstra 582e01c06f * Automatically upgrade <= 0.7 Nix stores to the new schema (so that 
existing user environments continue to work).
* `nix-store --verify': detect incomplete closures.
 2005-02-09 09:50:29 +00:00
Eelco Dolstra a37338815d * A GC setting `gc-keep-outputs' to specify whether output paths of 
derivations should be kept.
