2003-10-20	* Refactored the source tree.	Eelco Dolstra

2003-10-16	* Substitutes and nix-pull now work again.	Eelco Dolstra
	* Fixed a segfault caused by the buffering of stderr. * Fix now allows the specification of the full output path. This should be used with great care, since it by-passes the normal hash generation. * Incremented the version number to 0.4 (prerelease).
2003-10-10	* Reverse mappings for the successor and substitute mappings.	Eelco Dolstra

2003-10-08	* Get rid of identifiers since they are redundant now. This greatly	Eelco Dolstra
	simplifies stuff. * The format of Nix expressions and the database schema changed because of this, so it's best to delete old Nix installations.
2003-10-07	* Synchronise terminology with the ICSE paper (e.g., slice -> closure,	Eelco Dolstra
	fstate -> Nix expression). * Fix src/test.cc.
2003-08-01	* In normaliseFState(), wrap registration of the output paths and the	Eelco Dolstra
	normal form in a single transaction to ensure that if we crash, either everything is registered or nothing is. This is for recoverability: unregistered paths in the store can be deleted arbitrarily, while registered paths can only be deleted by running the garbage collector.
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.
2003-07-29	* `fstateRefs' now works on derive expressions as well. TODO: make	Eelco Dolstra
	this more efficient. * A flag `-n' in 'nix --query' to normalise the argument. Default is not to normalise.
2003-07-29	* Let `nix --install' print out the id of the normal form.	Eelco Dolstra
	* Some minor refactoring.
2003-07-22	* Substitutes now should produce a path with the same id as they are	Eelco Dolstra
	substituting for (obvious, really). * For greater efficiency, nix-pull/unnar will place the output in a path that is probably the same as what is actually needed, thus preventing a path copy. * Even if a output id is given in a Fix package expression, ensure that the resulting Nix derive expression has a different id. This is because Nix expressions that are semantically equivalent (i.e., build the same result) might be different w.r.t. efficiency or divergence. It is absolutely vital for the substitute mechanism that such expressions are not used interchangeably.
2003-07-21	* Changes to the command line syntax of Nix.	Eelco Dolstra
	* A function to find all Nix expressions whose output ids are completely contained in some set. Useful for uploading relevant Nix expressions to a shared cache.
2003-07-20	* Refactorings.	Eelco Dolstra
