2003-07-31	* Started using Berkeley DB environments. This is necessary for	Eelco Dolstra	1	-6/+6
	transaction support (but we don't actually use transactions yet).
2003-07-29	* Get garbage collection and cache population to work properly.	Eelco Dolstra	1	-4/+16
	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	1	-9/+25
	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	1	-26/+25
	* Some minor refactoring.
2003-07-24	* Fix message.	Eelco Dolstra	1	-1/+2

2003-07-24	* The `-v' flag no longer takes an argument; it should be repeated	Eelco Dolstra	1	-8/+8
	instead (e.g., `-vvvv' for lots of output). Default is to only print error messages.
2003-07-24	* Debug levels. Use `--verbose / -v LEVEL' to display only messages	Eelco Dolstra	1	-4/+2
	up to the given verbosity levels. These currently are: lvlError = 0, lvlNormal = 5, lvlDebug = 10, lvlDebugMore = 15 although only lvlError and lvlDebug are actually used right now.
2003-07-22	* Substitutes now should produce a path with the same id as they are	Eelco Dolstra	1	-6/+6
	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	* Check for errors.	Eelco Dolstra	1	-1/+1

2003-07-21	* Allow the output/expression id to be forced to a certain	Eelco Dolstra	1	-4/+3
	value; this potentially dangerous feature enables better sharing for those paths for which the content is known in advance (e.g., because a content hash is given). * Fast builds: if we can expand all output paths of a derive expression, we don't have to build.
2003-07-21	* Changes to the command line syntax of Nix.	Eelco Dolstra	1	-5/+44
	* 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	1	-0/+265
