Eelco Dolstra ebcccbd358 * Added a tool to find additional roots for the garbage collector, 
such as open files, current directories, mmaped files, etc.  This is
  inherently unportable, but it's easy to adapt this script to other
  platforms.  Currently we call `lsof' and try to read various bits in
  /proc/NNN.

  The goal is to prevent the garbage collector from removing store
  paths that are no longer reachable from a permanent root but that
  are still in use (for instance, after the user has done "nix-env -e"
  on a running program).

Eelco Dolstra 88e54153dc * Add a precise test for hashDerivatioModulo. 2006-07-19 15:49:29 +00:00
Eelco Dolstra 4f3725b167 * Better error messages (especially wrt types). 2006-07-19 15:36:15 +00:00
Eelco Dolstra e10b830251 * Doh! Of couse we cannot memoize across scopes. 2006-07-11 10:29:52 +00:00
Eelco Dolstra 2b4b0658fa * This expression has an undefined variable which isn't detected, so 
evaluation fails:

    error: impossible: undefined variable `gcc'
 2006-07-10 17:35:00 +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 a945fb7905 * `nix-env --upgrade --eq': only upgrade if the old version is equal 
to the new version.  This is actually useful.
 2006-06-27 12:17:25 +00:00
Eelco Dolstra f4a3a280db * Apply the ATerm aliasing patch so that Nix works correctly with gcc 4.1.x. 2006-06-22 13:01:42 +00:00
Eelco Dolstra dbf6d7e783 * Concurrent GC on Cygwin. 2006-06-20 17:48:10 +00:00
Eelco Dolstra cc51f9c539 * Oops. 2006-06-19 16:35:35 +00:00
Eelco Dolstra 5bb3444032 * _exit() doesn't seem to work right on Cygwin. 2006-06-19 16:24:15 +00:00
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
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 d7f40357e3 * Skip this test on Cygwin, too slow (and doesn't test anything Cygwin-specific). 2006-06-16 13:27:36 +00:00
Eelco Dolstra 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.
 2006-06-15 11:56:49 +00:00
Eelco Dolstra 49de87132f * Removed. 2006-06-15 09:16:55 +00:00
Eelco Dolstra 48e4a3231b 2006-06-14 13:31:23 +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 3a68622dda * Oops. 2006-06-14 11:52:22 +00:00
Rob Vermaas 370af25eff * Fix for a locking bug in Berkeley DB on Cygwin. 2006-06-07 15:27:17 +00:00
Eelco Dolstra 23960e92df * Minor cleanup. 2006-06-01 18:13:33 +00:00
Eelco Dolstra 2d456fc35a * On Cygwin, set the system type to i686-cygwin, and disable dynamic 
linking.
 2006-05-31 11:50:14 +00:00
Eelco Dolstra bb84984f3f * svn:ignore. 2006-05-31 10:58:47 +00:00
Eelco Dolstra 50fe85f016 * For fixed-output derivations, pass the environment variables listed 
in the attribute variable `impureEnvVars' from the caller to the
  builder.
 2006-05-31 09:51:45 +00:00
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
