2003-10-10	* New query `nix --query --predecessors' to print the predecessors of	Eelco Dolstra	1	-1/+14
	a Nix expression.
2003-10-08	* Get rid of identifiers since they are redundant now. This greatly	Eelco Dolstra	1	-57/+29
	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	1	-7/+6
	fstate -> Nix expression). * Fix src/test.cc.
2003-09-03	* Make nicer dot graphs. Also show the inner structure of slices.	Eelco Dolstra	1	-1/+1

2003-09-03	* Factored out dot graph generation into a separate file.	Eelco Dolstra	1	-60/+4

2003-08-20	* Use maps and sets in the FState data type. This ensures normalisation of	Eelco Dolstra	1	-2/+2
	slices and derivations w.r.t. order of paths, slice elements, etc.
2003-08-19	* Delete the temporary directories of failed builds by default, and an	Eelco Dolstra	1	-0/+2
	option `--keep-failed' to override this behaviour.
2003-08-01	* In normaliseFState(), wrap registration of the output paths and the	Eelco Dolstra	1	-2/+4
	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.
2003-07-31	* Started using Berkeley DB environments. This is necessary for	Eelco Dolstra	1	-0/+2
	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	-5/+10
	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	* Nicer dot graphs.	Eelco Dolstra	1	-1/+7

2003-07-29	* `fstateRefs' now works on derive expressions as well. TODO: make	Eelco Dolstra	1	-3/+13
	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	-1/+5
	* Some minor refactoring.
2003-07-28	* `nix --help'.	Eelco Dolstra	1	-36/+72
	* `nix --query --graph' to print a dot dependency graph of derive expressions.
2003-07-24	* The `-v' flag no longer takes an argument; it should be repeated	Eelco Dolstra	1	-10/+2
	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	-3/+13
	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	* `nix --query --expansion' (`-qe') to get any path with content	Eelco Dolstra	1	-3/+13
	corresponding to the given id.
2003-07-21	* In `--query --generators', print out paths, not ids.	Eelco Dolstra	1	-1/+1
	(There should really be a switch for this).
2003-07-21	* Changes to the command line syntax of Nix.	Eelco Dolstra	1	-72/+56
	* 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	* Argh, another short-write problem. Added wrappers around	Eelco Dolstra	1	-14/+3
	read()/write() to fix this once and for all.
2003-07-20	* Refactorings.	Eelco Dolstra	1	-2/+1

2003-07-17	* For debugging: `nix --verify' to check the consistency of the	Eelco Dolstra	1	-0/+9
	database and store.
2003-07-16	* The write() system call can write less than the requested	Eelco Dolstra	1	-3/+7
	number of bytes, e.g., in case of a signal like SIGSTOP. This caused `nix --dump' to fail sometimes. Note that this bug went unnoticed because the call to `nix --dump' is in a pipeline, and the shell ignores non-zero exit codes from all but the last element in the pipeline. Is there any way to check the result of the initial elements in the pipeline? (In other words, is it at all possible to write reliable shell scripts?)
2003-07-16	* Fix the -qr query.	Eelco Dolstra	1	-8/+4

2003-07-16	* Fix self-referential outputs.	Eelco Dolstra	1	-4/+5
	* Fix -qp query.
2003-07-15	* Get Fix and Nix to work again.	Eelco Dolstra	1	-20/+19

2003-07-11	* Fix handling of pipes (read(2) may not return the required	Eelco Dolstra	1	-5/+7
	number of bytes in one call).
2003-07-10	* A command to register successor fstate expressions.	Eelco Dolstra	1	-0/+18
	Unifying substitutes and successors isn't very feasible for now, since substitutes are only used when no path with a certain is known. Therefore, a normal form of some expression stored as a substitute would not be used unless the expression itself was missing.
2003-07-10	* The policy-free derivate sharing now almost works. :-) For any	Eelco Dolstra	1	-6/+19
	hash for which no local expansion is available, Nix can execute a `substitute' which should produce a path with such a hash. This is policy-free since Nix does not in any way specify how the substitute should work, i.e., it's an arbitrary (unnormalised) fstate expression. For example, `nix-pull' registers substitutes that fetch Nix archives from the network (through `wget') and unpack them, but any other method is possible as well. This is an improvement over the old Nix sharing scheme, which had a policy (fetching through `wget') built in. The sharing scheme doesn't work completely yet because successors from fstate rewriting have to be registered on the receiving side. Probably the whole successor stuff can be folded up into the substitute mechanism; this would be a nice simplification.
2003-07-10	* Get `nix-push' working again. It now uses Nix/Fix to create Nix	Eelco Dolstra	1	-9/+15
	archives (using the package in corepkgs/nar). * queryPathByHash -> expandHash, and it takes an argument specifying the target path (which may be empty). * Install the core Fix packages in $prefix/share/fix. TODO: bootstrap Nix and install Nix as a Fix package.
2003-07-09	* When computing the set of paths referenced by an expression, also	Eelco Dolstra	1	-3/+8
	include the paths of the subterms.
2003-07-08	* The output of a Derive() node is not a referenced path.	Eelco Dolstra	1	-1/+1

2003-07-08	* A command to query the paths referenced by an fstate expression.	Eelco Dolstra	1	-17/+73
	* Use a temporary directory for build actions.
2003-07-08	* Get `--dump' and `--delete' to work again.	Eelco Dolstra	1	-51/+17

	* addValue() can now import any dumpable FS object.
2003-06-20	* Flags to indicate how values are specified on the command line	Eelco Dolstra	1	-60/+116
	(--hash, --file, --name).
2003-06-20	* Refactoring: move dump function into archive.cc.	Eelco Dolstra	1	-0/+1

2003-06-18	* `nix --dump' command.	Eelco Dolstra	1	-3/+26

2003-05-30	* Send log output to stderr.	Eelco Dolstra	1	-2/+2
