2004-03-15	* Added a utility that can be used to produce nice HTML pages from Nix	Eelco Dolstra
	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).
2003-11-19	* nix-env: a tool to manage user environments.	Eelco Dolstra
	* Replace all directory reading code by a generic readDirectory() function.
2003-11-19	* Refactoring (step 2).	Eelco Dolstra

2003-11-19	* Refactoring: put the Nix expression evaluator in its own library so	Eelco Dolstra
	that it can be used by multiple programs.
2003-11-18	* "Fix expression" -> "Nix expression".	Eelco Dolstra
	* More refactoring.
2003-11-18	* nix -> nix-store, fix -> nix-instantiate.	Eelco Dolstra

2003-11-18	* libnix -> libstore.	Eelco Dolstra

2003-11-18	* Source tree refactoring.	Eelco Dolstra

2003-10-29	* Forked new version of Fix.	Eelco Dolstra

2003-10-20	* Finished refactoring the tree.	Eelco Dolstra

2003-10-07	* Synchronise terminology with the ICSE paper (e.g., slice -> closure,	Eelco Dolstra
	fstate -> Nix expression). * Fix src/test.cc.
2003-10-02	* Include the right files in a distribution.	Eelco Dolstra

2003-09-11	* Removed references to char_traits so that boost/format also works on	Eelco Dolstra
	GCC 2.95.
2003-09-03	* Factored out dot graph generation into a separate file.	Eelco Dolstra

2003-08-01	* normaliseFState() now locks all output paths prior to building, thus	Eelco Dolstra
	ensuring that simultaneous invocations of Nix don't clobber each other's builds. * Fixed a bug in `make install'.
2003-07-31	* Started using Berkeley DB environments. This is necessary for	Eelco Dolstra
	transaction support (but we don't actually use transactions yet).
2003-07-29	* Get garbage collection and cache population to work properly.	Eelco Dolstra
	Renamed `fstateRefs' to `fstateRequisites'. The semantics of this function is that it returns a list of all paths necessary to realise a given expression. For a derive expression, this is the union of requisites of the inputs; for a slice expression, it is the path of each element in the slice. Also included are the paths of the expressions themselves. Optionally, one can also include the requisites of successor expressions (to recycle intermediate results). * `nix-switch' now distinguishes between an expression and its normal form. Usually, only the normal form is registered as a root of the garbage collector. With the `--source-root' flag, it will also register the original expression as a root. * `nix-collect-garbage' now has a flag `--keep-successors' which causes successors not to be included in the list of garbage paths. * `nix-collect-garbage' now has a flag `--invert' which will print all paths that should not be garbage collected.
2003-07-28	* `nix --help'.	Eelco Dolstra
	* `nix --query --graph' to print a dot dependency graph of derive expressions.
2003-07-23	* Incorporated Berkeley DB and ATerm into the source tree.	Eelco Dolstra
	* `make dist'.
2003-07-22	* libdb_cxx-4 -> libdb_cxx	Eelco Dolstra

2003-07-20	* Refactorings.	Eelco Dolstra

2003-07-14	* After building, scan for actual file system references as	Eelco Dolstra
	opposed to declared references. This prunes the reference graph, thus allowing better garbage collection and more efficient derivate distribution.
2003-07-13	* Pass $(prefix) and other variables through -D..., not	Eelco Dolstra
	through config.h, to prevent silly Autoconf problems.
2003-07-13	* Generate the scripts so that we can substitute the prefix	Eelco Dolstra
	etc. correctly. * Fixed nix-switch.
2003-07-07	* Make dbRefs a mapping from Hash to [Path].	Eelco Dolstra

2003-07-07	* Refactoring on the file names.	Eelco Dolstra

2003-07-06	* A utility `nix-hash' to compute Nix path hashes.	Eelco Dolstra

2003-07-06	* Got Fix working again.	Eelco Dolstra

2003-07-04	* Refactoring: move initialisation and argument parsing into a shared	Eelco Dolstra
	file.
2003-07-04	* Caching of expression successors.	Eelco Dolstra

2003-06-25	* Minor cleanups.	Eelco Dolstra

2003-06-20	* Move most of Nix into a library (libnix.a).	Eelco Dolstra
	* Run `test' on `make check'.
2003-06-20	* Refactoring: move dump function into archive.cc.	Eelco Dolstra

2003-06-18	* Automake sucks.	Eelco Dolstra

2003-06-17	* Started integrating the new evaluation model into Nix.	Eelco Dolstra
	* Cleaned up command-line syntax.
2003-06-16	* Started implementing the new evaluation model.	Eelco Dolstra
	* Lots of refactorings. * Unit tests.
2003-06-15	* Refactoring: hash class.	Eelco Dolstra

2003-05-30	* Log the output of builders to $prefix/var/log/nix.	Eelco Dolstra

2003-05-26	* Some refactoring.	Eelco Dolstra

2003-05-25	* Prebuilt package sharing. We allow transparent binary deployment by	Eelco Dolstra
	sharing package directories (i.e., the result of building a Nix descriptor). `nix-pull-prebuilts' obtains a list of all known prebuilts by consulting the paths and URLs specified in $prefix/etc/nix/prebuilts.conf. The mappings ($pkghash, $prebuilthash) and ($prebuilthash, $location) are registered with Nix so that it can use the prebuilt with hash $prebuilthash when installing a package with hash $pkghash by downloading and unpacking $location. `nix-push-prebuilts' creates prebuilts for all packages for which no prebuilt is known to exist. It can then optionally upload these to the network through rsync. `nix-[pull\|push]-prebuilts' just provide a policy. Nix provides the mechanism through the `nix [export\|regprebuilt\|regurl]' commands.
2003-04-09	* We no longer use nix-populate standalone, rather we use it as a	Eelco Dolstra
	build action for `system' packages (like system.fix) that have dependencies on all packages we want to activate. So the command sequence to switch to a new activation configuration of the system would be: $ fix -i .../fixdescriptors/system.fix ... system.fix -> 89cf4713b37cc66989304abeb9ea189f $ nix-switch 89cf4713b37cc66989304abeb9ea189f * A nix-profile.sh script that can be included in .bashrc.
2003-04-08	* `Fix' is a high-level descriptor instantiator for Nix. It replaces	Eelco Dolstra
	nix-instantiate.
2003-04-06	* Better installation: make directories, create database.	Eelco Dolstra
	* Fixed the register script.
2003-04-04	* Autoconf / Automake configuration and building.	Eelco Dolstra
