Eelco Dolstra 245e26408f nix-env -q: Add a --json flag 2013-11-19 00:41:45 +01:00
Eelco Dolstra 5bc41d78ff Rename "attribute sets" to "sets"
We don't have any other kind of sets so calling them attribute sets is
unnecessarily verbose.

Eelco Dolstra 0220da3e10 Remove stray debug line 2013-09-06 17:20:19 +02:00
Eelco Dolstra 2c1ecf8e81 nix-env -i: Add a flag ‘--remove-all’ / ‘-r’
This is equivalent to running ‘nix-env -e '*'’ first, except that it
happens in a single transaction.  Thus, ‘nix-env -i pkgs...’ replaces
the profile with the specified set of packages.

The main motivation is to support declarative package management
(similar to environment.systemPackages in NixOS).  That is, if you
have a specification ‘profile.nix’ like this:

  with import <nixpkgs> {};
  [ thunderbird
    geeqie
    ...
  ]

then after any change to ‘profile.nix’, you can run:

  $ nix-env -f profile.nix -ir

to update the profile to match the specification.  (Without the ‘-r’
flag, if you remove a package from ‘profile.nix’, it won't be removed
from the actual profile.)

Suggested by @zefhemel.

Eelco Dolstra 88c07341a6 nix-env: Use wildcard match by default
That is, you don't need to pass '*' anymore, so

  nix-env -qa

is equivalent to

  nix-env -qa '*'

Eelco Dolstra 07a08bddf0 nix-env: Load files in ~/.nix-defexpr on demand
So if you do "nix-env -qa -A nixos", then other channels won't be
parsed/evaluated at all.

Eelco Dolstra c57ed84e28 Check for name collisions in the input Nix expressions 2013-09-03 15:25:51 +02:00
Eelco Dolstra ef4f5ba85e Work on Values instead of Exprs
This prevents some duplicate evaluation in nix-env and
nix-instantiate.

Also, when traversing ~/.nix-defexpr, only read regular files with the
extension .nix.  Previously it was reading files like
.../channels/binary-caches/<name>.  The only reason this didn't cause
problems is pure luck (namely, <name> shadows an actual Nix
expression, the binary-caches files happen to be syntactically valid
Nix expressions, and we iterate over the directory contents in just
the right order).

Eelco Dolstra 6f809194d7 Get rid of the parse tree cache
Since we already cache files in normal form (fileEvalCache), caching
parse trees is redundant.

Note that getting rid of this cache doesn't actually save much memory
at the moment, because parse trees are currently not freed / GC'ed.

Ivan Kozik 34bb806f74 Fix typos, especially those that end up in the Nix manual 2013-08-26 11:15:22 +02:00
Eelco Dolstra 9fa12fc201 Allow setting the profile location using $NIX_PROFILE
Fixes #69.
2012-12-12 16:01:46 +01:00
Eelco Dolstra 5ad89398d1 nix-env: Install all outputs of a derivation
If you explicitly install a package, presumably you want all of it.
So symlink all outputs in the user environment.
2012-12-04 14:20:36 +01:00
Eelco Dolstra d62fc71b85 Fix the ‘--prebuilt-only’ flag 2012-12-03 21:01:41 +01:00
Eelco Dolstra 4bb4d5479a Whitespace 2012-12-03 18:19:49 +01:00
Eelco Dolstra 8eed07cda4 nix-env -q --out-path: Support multiple outputs
We now print all output paths of a package, e.g.

  openssl-1.0.0i  bin=/nix/store/gq2mvh0wb9l90djvsagln3aqywqmr6vl-openssl-1.0.0i-bin;man=/nix/store/7zwf5r5hsdarl3n86dasvb4chm2xzw9n-openssl-1.0.0i-man;/nix/store/cj7xvk7fjp9q887359j75pw3pzjfmqf1-openssl-1.0.0i

or (in XML mode)

  <item attrPath="openssl" name="openssl-1.0.0i" system="x86_64-linux">
    <output name="bin" path="/nix/store/gq2mvh0wb9l90djvsagln3aqywqmr6vl-openssl-1.0.0i-bin" />
    <output name="man" path="/nix/store/7zwf5r5hsdarl3n86dasvb4chm2xzw9n-openssl-1.0.0i-man" />
    <output name="out" path="/nix/store/cj7xvk7fjp9q887359j75pw3pzjfmqf1-openssl-1.0.0i" />
  </item>

Eelco Dolstra 70f75be199 getDerivation(): Don't always quietly ignore assertion failure
Ignoring assertion failures makes some sense for nix-env -qa, but not
for nix-instantiate/nix-build or hydra-eval-jobs.
2012-10-04 15:22:25 -04:00
Eelco Dolstra a562d544d8 When ‘--help’ is given, just run ‘man’ to show the manual page
I.e. do what git does.  I'm too lazy to keep the builtin help text up
to date :-)

Also add ‘--help’ to various commands that lacked it
(e.g. nix-collect-garbage).
2012-10-03 16:40:09 -04:00
Eelco Dolstra 2bbc4a214e nix-env: Support ‘--repair’ flag 2012-10-03 15:35:42 -04:00
Eelco Dolstra 9fd9dedf12 nix-env --delete-generations: Support --dry-run flag
Fixes #43.
2012-09-13 18:05:04 -04:00
Eelco Dolstra ca94b38371 nix-env: Ignore manifest.nix when recursing into ~/.nix-defexpr
Channels are implemented using a profile now, and profiles contain a
manifest.nix file.  This should be ignored to prevent bogus packages
from showing up in nix-env.
2012-08-01 17:17:07 -04:00
Eelco Dolstra 97421eb5ec Refactor settings processing
Put all Nix configuration flags in a Settings object.
2012-07-30 19:55:41 -04:00
Eelco Dolstra 8c79100839 Merge branch 'master' into no-manifests 2012-07-26 15:14:33 -04:00
Eelco Dolstra b7fd2c2822 Use "#pragma once" to prevent repeated header file inclusion 2012-07-18 14:59:03 -04:00
Eelco Dolstra 09a6321aeb Replace hasSubstitutes() with querySubstitutablePaths()
querySubstitutablePaths() takes a set of paths, so this greatly
reduces daemon <-> client latency.
2012-07-11 17:52:18 -04:00
Eelco Dolstra 58ef4d9a95 Add a function queryValidPaths()
queryValidPaths() combines multiple calls to isValidPath() in one.
This matters when using the Nix daemon because it reduces latency.
For instance, on "nix-env -qas \*" it reduces execution time from 5.7s
to 4.7s (which is indistinguishable from the non-daemon case).
2012-07-11 11:08:47 -04:00
Eelco Dolstra 6586414bc7 nix-env: Determine which paths have substitutes in parallel 2012-07-11 10:14:06 -04:00
Eelco Dolstra 1aba0bf0fa nix-store -r: do substitutions in parallel
I.e. when multiple non-derivation arguments are passed to ‘nix-store
-r’ to be substituted, do them in parallel.
2012-06-27 16:58:15 -04:00
Eelco Dolstra ef902274fd Remove unnecessary "system" argument 2012-04-14 18:48:11 +02:00
Eelco Dolstra 34ea91b259 Include --keep-going in --help 2012-04-04 16:22:32 +02:00
Eelco Dolstra 48cea0d01e * Refactoring: Get rid of a few subdirectories in corepkgs/, and some
other simplifications.
* Use <nix/...> to locate the corepkgs.  This allows them to be
  overriden through $NIX_PATH.
* Use bash's pipefail option in the NAR builder so that we don't need
  to create a temporary file.
2012-01-03 00:16:29 +00:00
Eelco Dolstra b12b21825c * Allow '<nixexpr>' syntax to be used in nix-instantiate, nix-build
and nix-env, e.g.,

  $ nix-env -f '<nixpkgs>' -i patchelf

  or

  $ nix-build '<nixos/tests>' -A login.test
2011-12-01 16:41:43 +00:00
Eelco Dolstra 93227ff65c * Eliminate all uses of the global variable ‘store’ from libstore.
This should also fix:

    nix-instantiate: ./../boost/shared_ptr.hpp:254: T* boost::shared_ptr<T>::operator->() const [with T = nix::StoreAPI]: Assertion `px != 0' failed.

  which was caused by hashDerivationModulo() calling the ‘store’
  object (during store upgrades) before openStore() assigned it.
2011-08-31 21:11:50 +00:00
Eelco Dolstra 1ecc97b6bd * Add a Nix expression search path feature. Paths between angle
brackets, e.g.

    import <nixpkgs/pkgs/lib>

  are resolved by looking them up relative to the elements listed in
  the search path.  This allows us to get rid of hacks like

    import "${builtins.getEnv "NIXPKGS_ALL"}/pkgs/lib"

  The search path can be specified through the ‘-I’ command-line flag
  and through the colon-separated ‘NIX_PATH’ environment variable,
  e.g.,

    $ nix-build -I /etc/nixos ...

  If a file is not found in the search path, an error message is
  lazily thrown.
2011-08-06 16:05:24 +00:00
Eelco Dolstra 54945a2950 * Refactoring: move parseExprFromFile() and parseExprFromString() into
the EvalState class.
2011-08-06 13:02:55 +00:00
Eelco Dolstra 4ba6afaf48 * nix-env -ub' (--prebuilt-only') didn't really work because it
checked too soon whether substitutes are available.  That is, it did
  so for every available package, rather than those matching installed
  packages.  This was very slow and subject to assertion failures.  So
  do the check much later.  Idem for `nix-env -qab' and `nix-env -ib'.
2011-04-11 16:27:05 +00:00
Eelco Dolstra fb9368b5a0 * Sync with the trunk. 2010-11-16 12:49:47 +00:00
Eelco Dolstra e11e6fb1c6 * Handle out of memory condition. 2010-10-28 12:29:40 +00:00
Eelco Dolstra 43535499f3 * When allocating an attribute set, reserve enough space for all
elements.  This prevents the vector from having to resize itself.
2010-10-24 20:09:37 +00:00
Eelco Dolstra e0b7fb8f27 * Keep attribute sets in sorted order to speed up attribute lookups.
* Simplify the representation of attributes in the AST.
* Change the behaviour of listToAttrs() in case of duplicate names.
2010-10-24 19:52:33 +00:00
Eelco Dolstra 3f66cfb96b * Remove allocValues(). 2010-10-23 18:18:07 +00:00
Eelco Dolstra 41c45a9b31 * Store Value nodes outside of attribute sets. I.e., Attr now stores
a pointer to a Value, rather than the Value directly.  This improves
  the effectiveness of garbage collection a lot: if the Value is
  stored inside the set directly, then any live pointer to the Value
  causes all other attributes in the set to be live as well.
2010-10-22 14:47:42 +00:00
Eelco Dolstra 64c3325b0b * Make building against the Boehm GC a configure option. 2010-10-22 13:39:15 +00:00
Eelco Dolstra e879a0371b * Use the Boehm garbage collector to reclaim unused memory in the Nix
expression evaluator.
2010-10-20 11:38:30 +00:00
Eelco Dolstra 71dfe4b90b * Sync with the trunk. 2010-10-04 11:44:47 +00:00
Eelco Dolstra 923736df38 * Doh. Remove debug message. 2010-09-14 12:47:19 +00:00
Eelco Dolstra 587dc8aa00 * Sync with the trunk. 2010-08-04 17:48:29 +00:00
Eelco Dolstra 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.
2010-08-04 09:32:42 +00:00
Eelco Dolstra bf87cc44b4 * Sync with the trunk. 2010-06-21 07:55:38 +00:00
Eelco Dolstra 7343e6c8ae * Remove an accidentally committed debug statement. 2010-05-30 20:29:56 +00:00
Eelco Dolstra aa45027818 * Sync with the trunk. 2010-05-12 22:13:09 +00:00
Eelco Dolstra e2d5e40f4f * Keep track of the source positions of attributes. 2010-05-07 12:11:05 +00:00
Eelco Dolstra 84ce7ac76f * Store attribute positions in the AST and report duplicate attribute
errors with position info.
* For all positions, use the position of the first character of the
  first token, rather than the last character of the first token plus
  one.
2010-05-06 16:46:48 +00:00
Eelco Dolstra c82782f9a5 2010-04-27 09:05:11 +00:00
Eelco Dolstra fe2d869e04 * Store user environment manifests as a Nix expression in
$out/manifest.nix rather than as an ATerm.

  (Hm, I thought I committed this two days ago...)
2010-04-21 15:08:58 +00:00
Eelco Dolstra f3b8833a48 * Drop the dependency on the ATerm library. 2010-04-19 14:51:58 +00:00
Eelco Dolstra efc7a579e8 * Don't use the ATerm library for parsing/printing .drv files. 2010-04-19 13:46:58 +00:00
Eelco Dolstra 55b5ddd3ca * Added parsing of manifests in ATerm format. 2010-04-19 12:10:04 +00:00
Eelco Dolstra b7ff69eb7c * Refactoring: move the user environment stuff into its own module. 2010-04-19 10:47:56 +00:00
Eelco Dolstra 8bb0210fea * _combineChannels shouldn't be an integer. 2010-04-16 14:07:52 +00:00
Eelco Dolstra 02c1dac909 * In an nested with' where the inner with is a variable (with ...;
with someVar; ...'), the contents of the variable would be
  clobbered.  (The attributes in the outer `with' were added to the
  variable.)
2010-04-16 13:44:02 +00:00
Eelco Dolstra 011b5da0f4 * Get nix-env to compile again. 2010-04-14 09:39:06 +00:00
Eelco Dolstra 4d6ad5be17 * Don't use ATerms for the abstract syntax trees anymore. Not
finished yet.
2010-04-12 18:30:11 +00:00
Eelco Dolstra af2a372bb0 * Update autoCallFunction() and findAlongAttrPath(). 2010-04-07 15:47:06 +00:00
Eelco Dolstra d8cd3115d8 * Get nix-env to compile. 2010-03-31 19:12:08 +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 fefd467539 * `helpText' is now zero-terminated. 2010-02-24 13:24:27 +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 327a232c85 * Remove support for old (before Nix 0.12pre12020) databases. 2009-11-06 01:15:44 +00:00
Eelco Dolstra 6f7d7bc1de * Give a useful error message when an evaluation error occurs while
trying to upgrade a package.
2009-10-13 09:30:17 +00:00
Sander van der Burg 53a4981fa2 Added optional parameter which adds -lnsl -lsocket to make the Nix package manager work on OpenSolaris 2009-10-08 14:50:37 +00:00
Eelco Dolstra c6890d6b5c * Replace newlines in table output with spaces. 2009-07-02 08:52:12 +00:00
Eelco Dolstra 749dd97a54 * Support integers and lists of strings in meta fields. This is
useful for fields like meta.maintainers, meta.priority (which can be
  a proper integer now) and even meta.license (if there are multiple
  licenses).
2009-06-30 15:53:39 +00:00
Eelco Dolstra fa61ee70ee * Fix `--from-profile'. 2008-09-18 09:08:54 +00:00
Eelco Dolstra 7933cdc6dc * When writing the user environment manifest, filter out non-string
attributes from the meta attribute.  Not doing so caused nix-env to
  barf on the "psi" package, which has a meta.function attribute,
  the textual serialisation of which causes a gigantic string to be
  produced --- so big that it causes nix-env to run out of memory.

  Note however that "meta" really only should contain strings.  
  meta.function should be passthru.function.
2008-09-02 09:21:38 +00:00
Eelco Dolstra c4f1c2114b * Minor simplification. 2008-08-25 14:15:56 +00:00
Eelco Dolstra b428adc267 * Strip off the `.nix' suffix from the attribute name for files in
~/.nix-defexpr,  otherwise the attribute cannot be selected with the
  `-A' option.  Useful if you want to stick a Nix expression directly
  in ~/.nix-defexpr.
2008-08-25 13:31:57 +00:00
Eelco Dolstra 339c142009 * Use optimistic profile locking for nix-env operations like `-i' and
`-u'.  Instead of acquiring an exclusive lock on the profile for the
  entire duration of the operation, we just perform the operation
  optimistically (without an exclusive lock), and check at the end
  whether the profile changed while we were busy (i.e., the symlink
  target changed).  If so, the operation is restarted.  Restarting is
  generally cheap, since the build results are still in the Nix store.
  Most of the time, only the user environment has to be rebuilt.
2008-08-04 16:21:45 +00:00
Eelco Dolstra 001b3f06ec * `nix-env --set': support --dry-run. 2008-08-04 14:58:50 +00:00
Eelco Dolstra a1d310b6b5 * `nix-store --realise': print what paths will be built/downloaded,
just like nix-env.
* `nix-store --realise': --dry-run option.
2008-08-04 13:44:46 +00:00
Eelco Dolstra 5b1052663a * Always show what paths we're going to build/download (as in
--dry-run).  Maybe there should be an option to turn this on/off?
2008-08-04 13:11:09 +00:00
Eelco Dolstra c4f98941ed * nix-env --dry-run: show the total size of the substituter
downloads.
2008-08-04 12:29:04 +00:00
Eelco Dolstra 03427e76f1 * querySubstitutablePathInfo: work properly when run via the daemon.
* --dry-run: print the paths that we don't know how to build/substitute.
2008-08-04 11:44:50 +00:00
Eelco Dolstra d567baabbd * Export the nix-env derivation name parsing and version comparison
logic through the `parseDrvName' and `compareVersions' primops.
  This will allow expressions to easily check whether some dependency
  is a specific needed version or falls in some version range.  See
  tests/lang/eval-okay-versions.nix for examples.
2008-07-01 10:10:32 +00:00
Eelco Dolstra b0e92f6d47 * Merged the no-bdb branch (-r10900:HEAD
https://svn.nixos.org/repos/nix/nix/branches/no-bdb).
2008-06-09 13:52:45 +00:00
Eelco Dolstra e0ca671491 * More documentation. 2007-12-31 02:52:17 +00:00
Eelco Dolstra 633518628f * nix-env -e: support uninstalling by path, so that one can say
$ nix-env -e $(which firefox)

  or

    $ nix-env -e /nix/store/nywzlygrkfcgz7dfmhm5xixlx1l0m60v-pan-0.132

* nix-env -i: if an argument contains a slash anywhere, treat it as a
  path and follow it through symlinks into the Nix store.  This allows
  things like

    $ nix-build -A firefox
    $ nix-env -i ./result

* nix-env -q/-i/-e: don't complain when the `*' selector doesn't match
  anything.  In particular, `nix-env -q \*' doesn't fail anymore on an
  empty profile.
2007-11-29 16:18:24 +00:00
Eelco Dolstra bfea7b1f35 * Make the --prebuilt-only' / -b' option work not just for queries
but installations/upgrades as well.  So `nix-env -ub \*' will
  upgrade only those packages for which a substitute is available (or
  to be precise, it will upgrade each package to the highest version
  for which a substitute is available).
2007-10-29 14:31:45 +00:00
Eelco Dolstra f90d85107e 2007-10-22 12:05:30 +00:00
Eelco Dolstra 27f57c9018 * Ignore dangling symlinks in ~/.nix-defexpr. 2007-09-18 14:01:14 +00:00
Eelco Dolstra c8ea8a09b8 * nix-env -qa: make the "-A" flag do the expected thing, namely follow
the given attribute path (just as -A does with other option)
  (NIX-83).  So you can now say

  $ nix-env -qa -A nixpkgs_unstable.gnome \*
  atk-1.12.4
  esound-0.2.36
  ...

  to see the packages in the "gnome" attribute in Nixpkgs.

  To *print* the attribute path, you should now use "--attr-path" /
  "-P" (running out of letters...).
2007-09-17 19:24:07 +00:00
Eelco Dolstra 055608227f * nix-env: allow ~/.nix-defexpr to be a directory. If it is, then the
Nix expressions in that directory are combined into an attribute set
  {file1 = import file1; file2 = import file2; ...}, i.e. each Nix
  expression is an attribute with the file name as the attribute
  name.  Also recurses into directories.

* nix-env: removed the "--import" (-I) option which set the
  ~/.nix-defexpr symlink.

* nix-channel: don't use "nix-env --import", instead symlink
  ~/.nix-defexpr/channels.  So finally nix-channel --update doesn't
  override any default Nix expressions but combines with them.

  This means that you can have (say) a local Nixpkgs SVN tree and use
  it as a default for nix-env:

  $ ln -s .../path-to-nixpkgs-tree ~/.nix-defexpr/nixpkgs_svn

  and be subscribed to channels (including Nixpkgs) at the same time.
  (If there is any ambiguity, the -A flag can be used to
  disambiguate, e.g. "nix-env -i -A nixpkgs_svn.pan".)

Eelco Dolstra 4cad125e08 * Optionally warn about packages that give an assertion failure. 2007-08-06 16:08:09 +00:00
Eelco Dolstra 6da6fbfbe9 * Properly keep packages during upgrades. 2007-07-05 20:33:04 +00:00
Eelco Dolstra a9d15d4f43 * nix-env -i: instead of breaking package ties by version, break them
by priority and version install.  That is, if there are multiple
  packages with the same name, then pick the package with the highest
  priority, and only use the version if there are multiple packages
  with the same priority.

  This makes it possible to mark specific versions/variant in Nixpkgs
  more or less desirable than others.  A typical example would be a
  beta version of some package (e.g., "gcc-4.2.0rc1") which should not
  be installed even though it is the highest version, except when it
  is explicitly selected (e.g., "nix-env -i gcc-4.2.0rc1").

* Idem for nix-env -u, only the semantics are a bit trickier since we
  also need to take into account the priority of the currently
  installed package (we never upgrade to a lower priority, unless
  --always is given).
2007-05-01 20:33:18 +00:00
Eelco Dolstra bd1f66453a * `nix-env -q --xml --meta' to show all meta attributes. 2007-05-01 11:30:52 +00:00
Eelco Dolstra e20f0da22c * Doh. 2007-04-30 18:41:27 +00:00
Eelco Dolstra 89c1d2b202 * Package flag "keep" that prevents a package from being removed from
a user environment by an install or upgrade action.  This is
  particularly useful if you have a version installed that you don't
  want to upgrade (e.g., because the newer versions are broken).
  Example:

    $ nix-env -u zapping --dry-run
    (dry run; not doing anything)
    upgrading `zapping-0.9.6' to `zapping-0.10cvs6'

    $ nix-env --set-flag keep true zapping

    $ nix-env -u zapping --dry-run
    (dry run; not doing anything)

  However, "-e" will still uninstall the package.  (Maybe we should
  require the keep flag to be explicitly set to false before it can be
  uninstalled.)
2007-04-27 23:48:14 +00:00
Eelco Dolstra b7f0f65c19 * nix-env -q now has a flag --prebuilt-only (-b<) that causes nix-env
to show only those derivations whose output is already in the Nix
  store or that can be substituted (i.e., downloaded from somewhere).
  In other words, it shows the packages that can be installed “quickly”,
  i.e., don’t need to be built from source.
2007-04-26 14:20:31 +00:00
Eelco Dolstra 451dbf687f * nix-env now maintains meta info (from the `meta' derivation
attribute) about installed packages in user environments.  Thus, an
  operation like `nix-env -q --description' shows useful information
  not only on available packages but also on installed packages.

* nix-env now passes the entire manifest as an argument to the Nix
  expression of the user environment builder (not just a list of
  paths), so that in particular the user environment builder has
  access to the meta attributes.
  
* New operation `--set-flag' in nix-env to change meta info of
  installed packages.  This will be useful to pass per-package
  policies to the user environment builder (e.g., how to resolve
  collision or whether to disable a package (NIX-80)) or upgrade
  policies in nix-env (e.g., that a package should be "masked", that
  is, left untouched by upgrade actions).  Example:

  $ nix-env --set-flag enabled false ghc-6.4
2007-02-02 01:52:42 +00:00
Eelco Dolstra 71ceb1c161 * Handle multiple indirect symlinks when loading a Nix expression. 2007-01-15 14:50:25 +00:00
Eelco Dolstra e418976107 * Option --argstr for passing string arguments easily. (NIX-75) 2007-01-14 12:32:44 +00:00
Eelco Dolstra 7ace29dae7 * New operation `nix-env --set' which sets a user environment to a
single derivation specified by the argument.  This is useful when we
  want to have a profile for a single derivation, such as a server
  configuration.  Then we can just say (e.g.)

  $ nix-env -p /.../server-profile -f server.nix --set -A server

  We can't do queries or upgrades on such a profile, but we can do
  rollbacks.  The advantage over -i is that we don't have to worry
  about other packages having been installed in the profile
  previously; --set gets rid of them.
2006-12-12 19:06:02 +00:00
Eelco Dolstra e24d0201c2 * Doh! 2006-12-07 22:07:05 +00:00
Eelco Dolstra 4ca01065c3 * Rename all those main.cc files. 2006-12-07 20:47:30 +00:00
Eelco Dolstra a9c4f66cfb * Allow unprivileged users to run the garbage collector and to do
`nix-store --delete'.  But unprivileged users are not allowed to
  ignore liveness.
* `nix-store --delete --ignore-liveness': ignore the runtime roots as
  well.
2006-12-05 02:18:46 +00:00
Eelco Dolstra e25fad691a * Move addTempRoot() to the store API, and add another function
syncWithGC() to allow clients to register GC roots without needing
  write access to the global roots directory or the GC lock.
2006-12-02 16:41:36 +00:00
Eelco Dolstra 9c9cdb06d0 * Remove SwitchToOriginalUser, we're not going to need it anymore. 2006-12-02 14:34:14 +00:00
Eelco Dolstra 0565b5f2b3 * More remote operations.
* Added new operation hasSubstitutes(), which is more efficient than
  querySubstitutes().size() > 0.
2006-11-30 22:43:55 +00:00
Eelco Dolstra 9cf1948993 * Skeleton of remote store implementation. 2006-11-30 18:35:36 +00:00
Eelco Dolstra 6ecb840fd1 * Put building in the store API. 2006-11-30 18:02:04 +00:00
Eelco Dolstra e2ef5e07fd * Refactoring. There is now an abstract interface class StoreAPI
containing functions that operate on the Nix store.  One
  implementation is LocalStore, which operates on the Nix store
  directly.  The next step, to enable secure multi-user Nix, is to
  create a different implementation RemoteStore that talks to a
  privileged daemon process that uses LocalStore to perform the actual
  operations.
2006-11-30 17:43:04 +00:00
Eelco Dolstra 24737f279e * Backwards compatibility with old user environment manifests. 2006-10-17 14:01:45 +00:00
Eelco Dolstra 822dba2210 * Maintain the references for the user environment properly. 2006-10-17 12:15:15 +00:00
Eelco Dolstra 46b631b6c4 * Don't generate an empty drvPath attribute in the manifest. 2006-10-17 10:15:42 +00:00
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'.)
2006-10-16 15:55:34 +00:00
Eelco Dolstra 3632019b73 * Quick hack to let nix-install-package set the package name properly
(e.g., "java-front-0.9pre15899" instead of "java-front";
  particularly important when doing upgrades later on).
2006-09-25 14:00:59 +00:00
Eelco Dolstra e0afaf1857 * Wow, that bug has been there since r764. 2006-09-14 22:48:59 +00:00
Eelco Dolstra 86cbd93ec1 * nix-env --switch-generation / --list-generations /
--delete-generations: lock the profile to prevent (extremely
  unlikely) race conditions.
2006-09-14 22:33:53 +00:00
Eelco Dolstra 5c38c863bd * Fix a huge gaping hole in nix-env w.r.t. the garbage collector.
Nix-env failed to call addPermRoot(), which is necessary to safely
  add a new root.  So if nix-env started after and finished before the
  garbage collector, the user environment (plus all other new stuff)
  it built might be garbage collected, leading to a dangling symlink
  chain in ~/.nix-profile...

* Be more explicit if we block on the GC lock ("waiting for the big
  garbage collector lock...").

* Don't loop trying to create a new generation.  It's not necessary
  anymore since profiles are locked nowadays.
2006-09-14 22:30:33 +00:00
Eelco Dolstra a89a201598 * Missing #include. 2006-09-05 10:32:47 +00:00
Eelco Dolstra 75068e7d75 * Use a proper namespace.
* Optimise header file usage a bit.
* Compile the parser as C++.
2006-09-04 21:06:23 +00:00
Eelco Dolstra 4b66cebe7b * Remove those storePath attribute sets, we don't need 'em. 2006-08-25 17:09:55 +00:00
Eelco Dolstra f41297fdce * Allow --arg in nix-env as well, example:
$ nix-env -qa --system-filter \* --arg system '"powerpc-darwin"'

  to override the system from the default value (__currentSystem in
  all-packages.nix).
2006-08-23 16:33:21 +00:00
Eelco Dolstra 18e4ac0fc6 * `nix-instantiate --{eval|parse}-only --xml': print an XML
representation instead of an ATerm.
* Indent XML output.
2006-08-16 10:32:30 +00:00
Eelco Dolstra f1aa71a92f * Fix the help message wrt --attr. 2006-08-09 15:12:34 +00:00
Eelco Dolstra a0607be7f4 * Workaround for a bug (?) in GCC 2.95. 2006-08-07 19:48:38 +00:00
Eelco Dolstra 339e6f0e1d * `nix-env -q --xml': show query result in XML format for easier
automated processing.
2006-08-03 15:52:09 +00:00
Eelco Dolstra 4661282fde * `nix-instantiate ... --arg NAME VALUE': allow arguments to be passed
to functions from the command line.
* nix-build: started removing backticks.
2006-07-28 16:03:28 +00:00
Eelco Dolstra ca2238cf81 * Refactoring: get the selection path stuff out of getDerivations()
and put it into a separate function findAlongAttrPath().
2006-07-26 15:05:15 +00:00
Eelco Dolstra 0e6dc72a7a * Applied rbroek's patch from the branch at
https://svn.cs.uu.nl:12443/repos/trace/buildfarm-control/trunk/ext/nix/,
  with some modifications.  This allows `nix-env -qa' to show the
  attribute path that can be used to unambiguously install a package
  using `nix-env -i -A'.  Example:

    $ nix-env -f top-level/all-packages.nix -qaA subversion xorg-server
    subversionWithJava  subversion-1.2.3
    subversion          subversion-1.3.2
    subversion14        subversion-1.4.0pre-rc1
    xorg.xorgserver     xorg-server-1.1.0
2006-07-25 16:40:38 +00:00
Eelco Dolstra 5744dd5480 * Support the --attr / -A flag in nix-env as well. So now we can do,
e.g.,

  $ nix-env -i -A subversion xorg.xorgserver

  The main advantage over using symbolic names is that using attribute
  names is unambiguous and much, much faster.
2006-07-25 11:53:22 +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 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 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 0832956089 * Use the new ATermMap. 2006-05-04 12:21:08 +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 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 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 6dca5c9099 * When obtaining derivations from Nix expressions, ignore all
expressions that cause an assertion failure (like `assert system ==
  "i686-linux"').  This allows all-packages.nix in Nixpkgs to be used
  on all platforms, even if some Nix expressions don't work on all
  platforms.

  Not sure if this is a good idea; it's a bit hacky.  In particular,
  due to laziness some derivations might appear in `nix-env -qa' but
  disappear in `nix-env -qas' or `nix-env -i'.

  Commit 5000!
2006-03-08 16:03:58 +00:00
Eelco Dolstra c8bfb11b34 * `nix-env (-i|-u) --dry-run' now shows exactly which missing paths
will be built or substituted.
2006-03-06 11:21:15 +00:00
Eelco Dolstra 7ba1fd2029 * Regularise help text a bit. 2006-03-06 11:04:39 +00:00
Eelco Dolstra 74166f2f44 * db.hh shouldn't depend on the Berkeley DB headers. 2006-03-01 17:44:28 +00:00
