c25f2883b1 * Quadruple the Berkeley DB locking limits to get rid of out of memory
errors while running `nix-store --verify'.

fe122c5a15 * Removed nrWaitees field. It was redundant with waitees.size() and
could get out of sync if multiple input derivations mapped to the
  same closure expression (since waitees is a set).

eb233e728f * `--min-age' flag in nix-store and nix-collect-garbage to only delete
unreachable paths that haven't been used for N hours.  For instance,
  `nix-collect-garbage --min-age 168' only deletes paths that haven't
  been accessed in the last week.

  This is useful for instance in the build farm where many derivations
  can be shared between consecutive builds, and we wouldn't want a
  garbage collect to throw them all away.  We could of course register
  them as roots, but then we'd to unregister them at some point, which
  would be a pain to manage.  The `--min-age' flag gives us a sort of
  MRU caching scheme.

  BUG: this really shouldn't be in gc.cc since that violates
  mechanism/policy separation.

fdec72c6cc * `nix-collect-garbage' now actually performs a garbage collection, it
doesn't just print the set of paths that should be deleted.  So
  there is no more need to pipe the result into `nix-store --delete'
  (which doesn't even exist anymore).

818047881e * Put the garbage collector in nix-store: operation `--gc',
suboperations `--print-live', `--print-dead', and `--delete'.  The
  roots are not determined by nix-store; they are read from standard
  input.  This is to make it easy to customise what the roots are.

  The collector now no longer fails when store expressions are missing
  (which legally happens when using substitutes).  It never tries to
  fetch paths through substitutes.

  TODO: acquire a global lock on the store while garbage collecting.
  
* Removed `nix-store --delete'.

Eelco Dolstra
e77fbe0fa2 * On systems that have the setresuid() and setresgid() system calls to
set the real uid and gid to the effective uid and gid, the Nix
  binaries can be installed as owned by the Nix user and group instead
  of root, so no root involvement of any kind is necessary.

  Linux and FreeBSD have these functions.

2d35116c13 * Setuid support for sharing a Nix installation between multiple
users.

  If the configure flag `--enable-setuid' is used, the Nix programs
  nix-env, nix-store, etc. are installed with the setuid bit turned on
  so that they are executed as the user and group specified by
  `--with-nix-user=USER' and `--with-nix-group=GROUP', respectively
  (with defaults `nix' and `nix').

  The setuid programs drop all special privileges if they are executed
  by a user who is not a member of the Nix group.

  The setuid feature is a quick hack to enable sharing of a Nix
  installation between users who trust each other.  It is not
  generally secure, since any user in the Nix group can modify (by
  building an appropriate derivation) any object in the store, and for
  instance inject trojans into binaries used by other users.

  The setuid programs are owned by root, not the Nix user.  This is
  because on Unix normal users cannot change the real uid, only the
  effective uid.  Many programs don't work properly when the real uid
  differs from the effective uid.  For instance, Perl will turn on
  taint mode.  However, the setuid programs drop all root privileges
  immediately, changing all uids and gids to the Nix user and group.

8f1dcdfc0a * Make sure that no build hook is set by default in the tests.
* Don't use `seq' - some primitive, obsolete operating systems
  (Darwin) don't have it.

1eddee59f2 * The default verbosity level of all Nix commands is now lvlInfo.
* Builder output is written to standard error by default.
  * The option `-B' is gone.
  * The option `-Q' suppresses builder output.

The result of this is that most Nix invocations shouldn't need any
flags w.r.t. logging.

e3a50f7e25 * Creating a file nix-support/no-scan in the output path of a
derivation disables scanning for dependencies.  Use at your own
  risk.  This is a quick hack to speed up UML image generation (image
  are very big, say 1 GB).

  It would be better if the scanner were faster, and didn't read the
  whole file into memory.

39eaecbc98 * Slightly better heuristic for picking the canonical system type.
Now SuSE and Red Hat should yield the same type (`i686-linux').  Mac
  OS X should now give `powerpc-darwin' (i.e., the version number is
  gone).

638ce339a5 * Nix-instantiate now accepts sets of derivations (just like nix-env). 2004-07-01 14:25:26 +00:00
Eelco Dolstra
292d6468ec * Nix-env operations now by default filter out any derivations for
system types other than the current system.  I.e., `nix-env -i'
  won't install derivations for other system types, and `nix-env -q'
  won't show them.  The flag `--system-filter SYSTEM' can be used to
  override the system type used for filtering (but not for
  building!).  The value `*' can be used not to filter anything.

151e61fa5a * By default, `nix-env -i' now deletes previously installed

  The option `--preserve-installed / -P' overrides this behaviour.

24286e15c9 * `nix-env -u' now allows a specific version to be specified when
upgrading.

  This fixes a bug reported by Martin:

    $ nix-env -i foo-1.0
    $ nix-env -u foo-1.0
    upgrading foo-1.0 to foo-1.1

91dc023665 * Added a switch `--fallback'. From the manual:
Whenever Nix attempts to realise a derivation for which a closure is
  already known, but this closure cannot be realised, fall back on
  normalising the derivation.

  The most common scenario in which this is useful is when we have
  registered substitutes in order to perform binary distribution from,
  say, a network repository.  If the repository is down, the
  realisation of the derivation will fail.  When this option is
  specified, Nix will build the derivation instead.  Thus, binary
  installation falls back on a source installation.  This option is
  not the default since it is generally not desirable for a transient
  failure in obtaining the substitutes to lead to a full build from
  source (with the related consumption of resources).

b113edeab7 * A flag `--keep-going / -k' to keep building goals if one fails, as
much as possible.  (This is similar to GNU Make's `-k' flag.)

* Refactoring to implement this: previously we just bombed out when
  a build failed, but now we have to clean up.  In particular this
  means that goals must be freed quickly --- they shouldn't hang
  around until the worker exits.  So the worker now maintains weak
  pointers in order not to prevent garbage collection.

* Documented the `-k' and `-j' flags.
