2006-10-19 * toFile: maintain the references.Eelco Dolstra1-10/+4
2006-10-19 * Special derivation attribute `allowedReferences' that causes Nix toEelco Dolstra1-0/+31
check that the references of the output of a derivation are in the specified set. For instance, allowedReferences = []; specifies that the output cannot have any references. (This is useful, for instance, for the generation of bootstrap binaries for stdenv-linux, which must not have any references for purity). It could also be used to guard against undesired runtime dependencies, e.g., {gcc, dynlib}: derivation { ... allowedReferences = [dynlib]; } says that the output can refer to the path of `dynlib' but not `gcc'. A `forbiddedReferences' attribute would be more useful for this, though.
2006-10-17 * Backwards compatibility hack for user environments made by Nix <= 0.10.Eelco Dolstra1-0/+7
2006-10-17 * Backwards compatibility with old user environment manifests.Eelco Dolstra2-4/+8
2006-10-17 * Print out the offending path.Eelco Dolstra1-2/+3
2006-10-17 * An awful backwards compatibility hack.Eelco Dolstra1-0/+24
2006-10-17 * baseNameOf: paths don't have to be absolute.Eelco Dolstra1-1/+1
2006-10-17 * Maintain the references for the user environment properly.Eelco Dolstra1-1/+1
2006-10-17 * toPath: should be the identity on paths.Eelco Dolstra1-3/+1
2006-10-17 * dirOf: return a path if the argument is a path.Eelco Dolstra1-2/+6
2006-10-17 * toString: don't copy paths. So toString can be used to passEelco Dolstra1-3/+4
non-store paths to a builder.
2006-10-17 * Do the path check on the normal form.Eelco Dolstra1-2/+5
2006-10-17 * Don't generate an empty drvPath attribute in the manifest.Eelco Dolstra1-6/+6
2006-10-16 * Big cleanup of the semantics of paths, strings, contexts, stringEelco Dolstra17-391/+326
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'.)
2006-10-13 * A helpful message.Eelco Dolstra1-0/+2
2006-10-13 * Don't crash when upgrading the Berkeley DB environment.Eelco Dolstra1-1/+6
2006-10-11 * Removed URIs from the evaluator (NIX-66). They are now just anotherEelco Dolstra6-13/+4
kind of notation for strings.
2006-10-10 * Quick hack to fix NIX-67: evaluation result differing if the NixEelco Dolstra2-13/+16
expression resides in the store.
2006-10-10 * `import': unwrap the context. Necessary to make `import (x + y)'Eelco Dolstra1-13/+14
work, where x is a store path.
2006-10-05 * Documented nix-store --dump / --restore.Eelco Dolstra1-1/+1
2006-10-03 * toXML: propagate the context to allow derivations to be used in theEelco Dolstra4-10/+21
argument.
2006-10-03 * toFile: added an additional argument to specify the store pathEelco Dolstra3-4/+40
suffix, e.g., `builtins.toFile "builder.sh" "..."'. * toFile: handle references to other files correctly.
2006-10-02 * Finally, a real "let" syntax: `let x = ...; ... z = ...; in ...'.Eelco Dolstra2-1/+4
2006-10-02 * Hack for Bison 2.3 compatability.Eelco Dolstra2-2/+14
2006-09-27 * Fix setuid builds.Eelco Dolstra2-9/+9
2006-09-25 * Quick hack to let nix-install-package set the package name properlyEelco Dolstra1-1/+11
(e.g., "java-front-0.9pre15899" instead of "java-front"; particularly important when doing upgrades later on).
2006-09-24 * The result of a concatenation with a derivation on the left-handEelco Dolstra2-4/+13
side should be a path, I guess. * Handle paths that are in the store but not direct children of the store directory. * Ugh, hack to prevent double context wrapping.
2006-09-24 * Primop `toPath' to convert a string to a path.Eelco Dolstra1-7/+26
* Primop `pathExists' to check for path existence.
2006-09-24 * Builtin function `getEnv' for getting environment variables.Eelco Dolstra1-6/+18
2006-09-24 * lessThan primitive for integer comparison.Eelco Dolstra1-0/+9
2006-09-22 * Builtin function `add' to add integers.Eelco Dolstra3-0/+20
* Put common test functions in tests/lang/lib.nix.
2006-09-22 * Added a builtin function `isList' to test whether a value is a list.Eelco Dolstra1-0/+9
With this primitive, a list-flattening function can be implemented (NIX-55, example is in tests/lang/eval-okay-flatten.nix).
2006-09-22 * Builtin functions `head' and `tail' to return the head and tail ofEelco Dolstra1-0/+25
list. Useful for lots of things, such as implementing a fold function (see NIX-30, example is in tests/lang/eval-okay-list.nix).
2006-09-22 * New builtin functions builtins.{hasAttr, getAttr} to check forEelco Dolstra1-0/+16
attribute existence and to return an attribute from an attribute set, respectively. Example: `hasAttr "foo" {foo = 1;}'. They differ from the `?' and `.' operators in that the attribute name is an arbitrary expression. (NIX-61)
2006-09-22 * Use a bounded amount of memory in scanForReferences() by not readingEelco Dolstra1-9/+26
regular files into memory all at once.
2006-09-22 * Don't allocate the buffer twice.Eelco Dolstra1-7/+9
2006-09-22 * Don't allocate more than SIZE_MAX bytes.Eelco Dolstra1-0/+7
2006-09-21 * GC options in nix-store --help (NIX-15).Eelco Dolstra1-1/+10
2006-09-21 * Fix comment.Eelco Dolstra1-3/+1
2006-09-20 * Shut up a warning.Eelco Dolstra1-0/+1
2006-09-20 * Print a better error message for wrong hashes (NIX-49).Eelco Dolstra3-4/+16
2006-09-14 * Wow, that bug has been there since r764.Eelco Dolstra1-2/+2
2006-09-14 * nix-env --switch-generation / --list-generations /Eelco Dolstra1-0/+9
--delete-generations: lock the profile to prevent (extremely unlikely) race conditions.
2006-09-14 * Fix a huge gaping hole in nix-env w.r.t. the garbage collector.Eelco Dolstra3-22/+26
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.
2006-09-11 * Support `++'.Eelco Dolstra1-6/+14
* More follow restrictions on layout.
2006-09-08 * Remove debug message.Eelco Dolstra1-1/+0
2006-09-05 * Missing #include.Eelco Dolstra1-0/+2
2006-09-05 * Sone missing #includes.Eelco Dolstra3-1/+3
2006-09-04 * Move setuid stuff to libutil.Eelco Dolstra4-142/+146
* Install libexpr header files.
2006-09-04 * Install header files in /nix/include/nix.Eelco Dolstra5-14/+25
