2012-02-15	On Linux, make the Nix store really read-only by using the immutable bit	Eelco Dolstra	1	-2/+24
	I was bitten one time too many by Python modifying the Nix store by creating *.pyc files when run as root. On Linux, we can prevent this by setting the immutable bit on files and directories (as in ‘chattr +i’). This isn't supported by all filesystems, so it's not an error if setting the bit fails. The immutable bit is cleared by the garbage collector before deleting a path. The only tricky aspect is in optimiseStore(), since it's forbidden to create hard links to an immutable file. Thus optimiseStore() temporarily clears the immutable bit before creating the link.
2010-11-16	* Store the size of a store path in the database (to be precise, the	Eelco Dolstra	1	-1/+1
	size of the NAR serialisation of the path, i.e., `nix-store --dump PATH'). This is useful for Hydra.
2010-06-04	* Applied a patch from David Brown to prevent `nix-store --optimise'	Eelco Dolstra	1	-1/+15
	from failing on rename() on BtrFS.
2009-09-24	* And some more.	Eelco Dolstra	1	-0/+1

2009-04-21	* Use foreach in a lot of places.	Eelco Dolstra	1	-2/+2

2008-06-18	* `nix-store --optimise': handle files with >= 32000 hard links.	Eelco Dolstra	1	-6/+31
	(There can easily be more than 32000 occurrences of the empty file.)
2008-06-18	* Some refactoring: put the GC options / results in separate structs.	Eelco Dolstra	1	-0/+1
	* The garbage collector now also prints the number of blocks freed.
2008-06-09	* Merged the no-bdb branch (-r10900:HEAD	Eelco Dolstra	1	-0/+129
	https://svn.nixos.org/repos/nix/nix/branches/no-bdb).
