2006-11-24 * Doh! Path sizes need to be computed recursively of course.Eelco Dolstra3-6/+28
(NIX-70)
2006-11-24 * Dead files.Eelco Dolstra2-12/+0
2006-11-18 * Turn off synchronisation between C and C++ I/O functions. ThisEelco Dolstra2-1/+3
gives a huge speedup in operations that read or write from standard input/output. (So libstdc++'s I/O isn't that bad, you just have to call std::ios::sync_with_stdio(false).) For instance, `nix-store --register-substitutes' went from 1.4 seconds to 0.1 seconds on a certain input. Another victory for Valgrind.
2006-11-13 * Remove the undocumented `noscan' feature. It's no longer necessaryEelco Dolstra1-15/+12
now that reference scanning is sufficiently streamy.
2006-11-13 * Magic attribute `exportReferencesGraph' that allows the referencesEelco Dolstra2-20/+60
graph to be passed to a builder. This attribute should be a list of pairs [name1 path1 name2 path2 ...]. The references graph of each `pathN' will be stored in a text file `nameN' in the temporary build directory. The text files have the format used by `nix-store --register-validity'. However, the deriver fields are left empty. `exportReferencesGraph' is useful for builders that want to do something with the closure of a store path. Examples: the builders that make initrds and ISO images for NixOS. `exportReferencesGraph' is entirely pure. It's necessary because otherwise the only way for a builder to get this information would be to call `nix-store' directly, which is not allowed (though unfortunately possible).
2006-11-13 * Option `--reregister' in `nix-store --register-validity'. We needEelco Dolstra1-8/+18
this in the NixOS installer (or in the buildfarm) to ensure that the cryptographic hash of the path contents still matches the actual contents.
2006-11-03 * Fix importing of derivation outputs.Eelco Dolstra1-2/+9
2006-10-30 * readFile: don't overflow the stack on large files.Eelco Dolstra1-1/+15
2006-10-28 * `nix-store --read-log / -l PATH' shows the build log of PATH, ifEelco Dolstra4-4/+43
available. For instance, $ nix-store -l $(which svn) | less lets you read the build log of the Subversion instance in your profile. * `nix-store -qb': if applied to a non-derivation, take the deriver.
2006-10-23 * Some better error messages.Eelco Dolstra2-5/+12
2006-10-19 * Better message.Eelco Dolstra1-1/+1
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
