* Documented release procedures.
2004-04-23 * Pass SYSTEM through config.h, and allow spaces.Eelco Dolstra3-2/+6
2004-04-22 * Look for GC roots in @localstatedir@/nix/gcroots.Eelco Dolstra2-20/+58
2004-04-22 * Don't create $(localstatedir)/nix/profiles if --disable-init-stateEelco Dolstra2-3/+1
is specified.
2004-04-21 * Dist error.Eelco Dolstra1-1/+1
2004-04-21 * Channels. These allow you to stay current with an evolving set ofEelco Dolstra10-52/+194
Nix expressions. To subscribe to a channel (needs to be done only once): nix-channel --add \ http://catamaran.labs.cs.uu.nl/dist/nix/channels/nixpkgs-unstable This just adds the given URL to ~/.nix-channels (which can also be edited manually). To update from all channels: nix-channel --update This fetches the latest expressions and pulls cache manifests. The default Nix expression (~/.nix-defexpr) is made to point to the conjunction of the expressions downloaded from all channels. So to update all installed derivations in the current user environment: nix-channel --update nix-env --upgrade '*' If you are really courageous, you can put this in a cronjob or something. You can subscribe to multiple channels. It is not entirely clear what happens when there are name clashes between derivations from different channels. From nix-env/main.cc it appears that the one with the lowest (highest?) hash will be used, which is pretty meaningless.
2004-04-21 * Do initialise state (the DB etc.) when doing a `make install',Eelco Dolstra4-8/+18
unless `--disable-init-state' is passed to configure.
2004-04-21 * Recurse into attribute sets and lists when getting derivations fromEelco Dolstra1-0/+4
an expression.
2004-04-15 * Allow extra parameters to be passed to Curl through the `CURL_FLAGS'Eelco Dolstra1-1/+1
environment variable. This is useful for passing authentication information (it won't show up in `ps'). Hacky - nix-push should abstract over the use of Curl.
2004-04-14 * Use @storedir@, not @prefix@/store.Eelco Dolstra1-1/+1
2004-04-14 * `*.gcroot' files can now containing multiple roots.Eelco Dolstra1-3/+7

2004-04-06 * Distributed the wrong file.Eelco Dolstra1-2/+1
2004-04-06 * Make the creation of user environments much faster and more storageEelco Dolstra1-45/+66
efficient by creating only a single symlink to entire directory trees unless a collission occurs.
2004-04-06 * Fail if prerequisites are missing.Eelco Dolstra1-11/+14
2004-04-06 * Switched from wget to curl.Eelco Dolstra11-36/+47
* Made the dependencies on bzip2 and the shell explicit.
2004-04-05 * When something goes wrong in the evaluation of a Nix expression,Eelco Dolstra8-89/+200
print a nice backtrace of the stack, rather than vomiting a gigantic (and useless) aterm on the screen. Example: error: while evaluating file `.../pkgs/system/test.nix': while evaluating attribute `subversion' at `.../pkgs/system/all-packages-generic.nix', line 533: while evaluating function at `.../pkgs/applications/version-management/subversion/default.nix', line 1: assertion failed at `.../pkgs/applications/version-management/subversion/default.nix', line 13 Since the Nix expression language is lazy, the trace may be misleading. The purpose is to provide a hint as to the location of the problem.
2004-04-02 * Print a more useful error message in case of an invalid derivationEelco Dolstra1-1/+6
binding.
2004-03-30 * The recent change in nixpkgs of calling `stdenv.mkDerivation'Eelco Dolstra2-2/+11
instead of `derivation' triggered a huge slowdown in the Nix expression evaluator. Total execution time of `nix-env -qa' went up by a factor of 60 or so. This scalability problem was caused by expressions such as (x: y: ... x ...) a b where `a' is a large term (say, the one in `all-packages-generic.nix'). Then the first beta-reduction would produce (y: ... a ...) b by substituting `a' for `x'. The second beta-reduction would then substitute `b' for `y' into the body `... a ...', which is a large term due to `a', and thus causes a large traversal to be performed by substitute() in the second reduction. This is however entirely redundant, since `a' cannot contain free variables (since we never substitute below a weak head normal form). The solution is to wrap substituted terms into a `Closed' constructor, i.e., subst(subs, Var(x)) = Closed(e) iff subs[x] = e have substitution not descent into closed terms, subst(subs, Closed(x)) = Closed(x) and otherwise ignore them for evaluation, eval(Closed(x)) = eval(x). * Fix a typo that caused incorrect substitutions to be performed in simple lambdas, e.g., `(x: x: x) a' would reduce to `(x: a)'.
2004-03-29 * Specify Perl as a dependency for the RPM.Eelco Dolstra1-0/+1
2004-03-28 * Added an operator `?' to test for attribute existence, e.g.,Eelco Dolstra2-1/+10
`attrs ? x' yields true iff `attrs' has an attribute named `x'.
2004-03-28 * Added an operator `~' to select paths within a derivation. E.g.,Eelco Dolstra3-0/+16
{stdenv, bash}: derivation { builder = bash ~ /bin/sh; args = ["-e" "-x" ./builder.sh]; ... } Here the attribute `builder' will evaluate to, e.g., `/nix/store/1234abcd...-bash-2.0.1/bin/sh'.
2004-03-28 * Added plain lambdas, e.g., `let { id = x: x; const = x: y: x; }'.Eelco Dolstra5-37/+63
`bla:' is now no longer parsed as a URL. * Re-enabled support for the `args' attribute in derivations to specify command line arguments to the builder, e.g., ... builder = /usr/bin/python; args = ["-c" ./builder.py]; ...
2004-03-27 * Disallow the Nix store or any of its parents from being symlinks.Eelco Dolstra2-11/+37
This is because the contents of these symlinks are not incorporated into the hashes of derivations, and could therefore cause a mismatch between the build system and the target system. E.g., if `/nix/store' is a symlink to `/data/nix/store', then a builder could expand this path and store the result. If on the target system `/nix/store' is not a symlink, or is a symlink that points somewhere else, we have a dangling pointer. The trigger for this change is that gcc 3.3.3 does exactly that (it applies realpath() to some files, such as libraries, which causes our impurity checker to bail out.) An annoying side-effect of this change is that it makes it harder to move the Nix store to a different file system. On Linux, bind mounts can be used instead of symlink for this purpose (e.g., `mount -o bind /data/nix/store /nix/store').
2004-03-27 * Do not close a nesting level twice after close() has beenEelco Dolstra2-1/+11
called explicitly on a Nest object.
2004-03-22 * Some more nesting.Eelco Dolstra3-14/+40
2004-03-22 * Nix now has three different formats for the log information itEelco Dolstra3-7/+52
writes to stderr: - `pretty': the old nested style (default) - `escapes': uses escape codes to indicate nesting and message level; can be processed using `log2xml' - `flat': just plain text, no nesting These can be set using `--log-type TYPE' or the NIX_LOG_TYPE environment variable.
2004-03-19 * `null' is a normal form.Eelco Dolstra1-8/+11
2004-03-18 * Escape codes to force line breaks to be ignored.Eelco Dolstra1-1/+9
2004-03-18 * Added an extra escape code to signal "unimportant" messages. If a tree ↵Eelco Dolstra3-9/+46
only has unimportant messages, it is collapsed by the default. * Also added an optional integer argument to the escape code for opening a nesting level to indicate lack of importance. If set, the tree is collapsed by default.
2004-03-18 * Collapsable trees.Eelco Dolstra3-5/+65
2004-03-18 * Use unordered lists, which is more sensible semantically forEelco Dolstra2-50/+43
representing tree structures.
2004-03-18 * Don't use tables. Konqueror likes this much better.Eelco Dolstra2-71/+33
2004-03-17 * Display the popup directly over the abbreviation.Eelco Dolstra1-2/+2
2004-03-17 * A simpler way of implementing the store reference popups, thanks toEelco Dolstra2-17/+14
Martin and CSS guru Martijn Vermaat.
2004-03-16 * Store paths are now abbreviated in the generated HTML file.Eelco Dolstra3-13/+89
Hovering over the abbreviated path will reveal the full path. This probably only works in Mozilla.
2004-03-15 * Added a utility that can be used to produce nice HTML pages from NixEelco Dolstra6-1/+240
build logs. The program `log2xml' converts a Nix build log (read from standard input) into XML file that can then be converted to XHTML by the `log2html.xsl' stylesheet. The CSS stylesheet `logfile.css' is necessary to make it look good. This is primarily useful if the log file has a *tree structure*, i.e., that sub-tasks such as the various phases of a build (unpack, configure, make, etc.) or recursive invocations of Make are represented as such. While a log file is in principle an unstructured plain text file, builders can communicate this tree structure to `log2xml' by using escape sequences: - "\e[p" starts a new nesting level; the first line following the escape code is the header; - "\e[q" ends the current nesting level. The generic builder in nixpkgs (not yet committed) uses this. It shouldn't be to hard to patch GNU Make to speak this protocol. Further improvements to the generated HTML pages are to allow collapsing/expanding of subtrees, and to abbreviate store paths (but to show the full path by hovering the mouse over it).
2004-03-15 * Make perl a dependency of Nix.Eelco Dolstra9-7/+15
2004-03-12 * Set the NIX_STORE and NIX_BUILD_TOP environment variables inEelco Dolstra3-3/+19
builders to point to the store and the temporary build directory, respectively. Useful for purity checking. * Also set TEMPDIR, TMPDIR, TEMP, and TEMP to NIX_BUILD_TOP to make sure that tools in the builder store temporary files in the right location.
2004-02-20 * Use $(storedir) instead of $(prefix)/store.Eelco Dolstra3-3/+4
2004-02-19 * Resolve an ambiguity between ifs and attribute selection, e.g., `ifEelco Dolstra1-3/+7
b then x else y.z'.
2004-02-16 * Don't build ATerm library if we don't need to.Eelco Dolstra1-0/+4
2004-02-16 * Allow linking against an external Berkeley DB / ATerm library.Eelco Dolstra11-18/+47
