2013-08-26	Fix typos, especially those that end up in the Nix manual	Ivan Kozik

2013-06-07	Process stderr from substituters while doing have/info queries	Eelco Dolstra

2012-07-18	Use "#pragma once" to prevent repeated header file inclusion	Eelco Dolstra

2011-12-16	* importPath() -> importPaths(). Because of buffering of the input	Eelco Dolstra
	stream it's now necessary for the daemon to process the entire sequence of exported paths, rather than letting the client do it.
2011-12-16	* Avoid expensive conversions from char arrays to STL strings.	Eelco Dolstra

2011-12-16	* Make the import operation through the daemon much more efficient	Eelco Dolstra
	(way fewer roundtrips) by allowing the client to send data in bigger chunks. * Some refactoring.
2011-12-16	* Clean up exception handling.	Eelco Dolstra

2011-12-15	* Refactoring: move sink/source buffering into separate classes.	Eelco Dolstra
	* Buffer the HashSink. This speeds up hashing a bit because it prevents lots of calls to the hash update functions (e.g. nix-hash went from 9.3s to 8.7s of user time on the closure of my /var/run/current-system).
2011-12-15	* Buffer reads in FdSource. Together with write buffering, this	Eelco Dolstra
	significantly cuts down the number of syscalls (e.g., for "nix-store -qR /var/run/current-system" via the daemon, it reduced the number of syscalls in the client from 29134 to 4766 and in the daemon from 44266 to 20666).
2011-12-14	* Buffer writes in FdSink. This significantly reduces the number of	Eelco Dolstra
	system calls / context switches when dumping a NAR and in the worker protocol.
2009-03-22	* NAR archives: handle files larger than 2^32 bytes. Previously it	Eelco Dolstra
	would just silently store only (fileSize % 2^32) bytes. * Use posix_fallocate if available when unpacking archives. * Provide a better error message when trying to unpack something that isn't a NAR archive.
2008-12-11	* Open the connection to the daemon lazily (on demand) so that	Eelco Dolstra
	read-only operations (like nix-env -qa) work properly when the daemon isn't running.
2008-12-03	* A simple API for parsing NAR archives.	Eelco Dolstra

2008-06-18	* Some refactoring: put the GC options / results in separate structs.	Eelco Dolstra
	* The garbage collector now also prints the number of blocks freed.
2006-12-12	* New primop builtins.filterSource, which can be used to filter files	Eelco Dolstra
	from a source directory. All files for which a predicate function returns true are copied to the store. Typical example is to leave out the .svn directory: stdenv.mkDerivation { ... src = builtins.filterSource (path: baseNameOf (toString path) != ".svn") ./source-dir; # as opposed to # src = ./source-dir; } This is important because the .svn directory influences the hash in a rather unpredictable and variable way.
2006-11-30	* More remote operations.	Eelco Dolstra
	* Added new operation hasSubstitutes(), which is more efficient than querySubstitutes().size() > 0.
2006-11-30	* When NIX_REMOTE is set to "slave", fork off nix-worker in slave	Eelco Dolstra
	mode. Presumably nix-worker would be setuid to the Nix store user. The worker performs all operations on the Nix store and database, so the caller can be completely unprivileged. This is already much more secure than the old setuid scheme, since the worker doesn't need to do Nix expression evaluation and so on. Most importantly, this means that it doesn't need to access any user files, with all resulting security risks; it only performs pure store operations. Once this works, it is easy to move to a daemon model that forks off a worker for connections established through a Unix domain socket. That would be even more secure.
2006-11-30	* Skeleton of the privileged worker program.	Eelco Dolstra
	* Some refactoring: put the NAR archive integer/string serialisation code in a separate file so it can be reused by the worker protocol implementation.
