2016-11-26	Revert "Get rid of unicode quotes (#1140)"	Eelco Dolstra	1	-2/+2
	This reverts commit f78126bfd6b6c8477fcdbc09b2f98772dbe9a1e7. There really is no need for such a massive change...

2016-02-26	FdSource: track number of bytes read	Eelco Dolstra	1	-4/+6

2016-02-24	Remove bad daemon connections from the pool	Eelco Dolstra	1	-6/+17
	This is necessary for long-running processes like hydra-queue-runner: if a nix-daemon worker is killed, we need to stop reusing that connection.
2015-09-03	Implement buildDerivation() via the daemon	Eelco Dolstra	1	-0/+1

2015-07-20	More cleanup	Eelco Dolstra	1	-16/+27

2015-07-17	Allow remote builds without sending the derivation closure	Eelco Dolstra	1	-0/+8
	Previously, to build a derivation remotely, we had to copy the entire closure of the .drv file to the remote machine, even though we only need the top-level derivation. This is very wasteful: the closure can contain thousands of store paths, and in some Hydra use cases, include source paths that are very large (e.g. Git/Mercurial checkouts). So now there is a new operation, StoreAPI::buildDerivation(), that performs a build from an in-memory representation of a derivation (BasicDerivation) rather than from a on-disk .drv file. The only files that need to be in the Nix store are the sources of the derivation (drv.inputSrcs), and the needed output paths of the dependencies (as described by drv.inputDrvs). "nix-store --serve" exposes this interface. Note that this is a privileged operation, because you can construct a derivation that builds any store path whatsoever. Fixing this will require changing the hashing scheme (i.e., the output paths should be computed from the other fields in BasicDerivation, allowing them to be verified without access to other derivations). However, this would be quite nice because it would allow .drv-free building (e.g. "nix-env -i" wouldn't have to write any .drv files to disk). Fixes #173.
2014-06-12	Don't use member initialisers	Eelco Dolstra	1	-4/+4
	They're a little bit too recent (only supported since GCC 4.7). http://hydra.nixos.org/build/11851475
2014-06-12	Fix bogus warnings about dumping large paths	Eelco Dolstra	1	-2/+2
	Also, yay for C++11 non-static initialisers.
2014-06-10	Print a warning when loading a large path into memory	Eelco Dolstra	1	-4/+3
	I.e. if you have a derivation with src = ./huge-directory; you'll get a warning that this is not a good idea.
2013-08-26	Fix typos, especially those that end up in the Nix manual	Ivan Kozik	1	-1/+1

2013-06-07	Process stderr from substituters while doing have/info queries	Eelco Dolstra	1	-0/+2

2012-07-18	Use "#pragma once" to prevent repeated header file inclusion	Eelco Dolstra	1	-5/+1

2011-12-16	* importPath() -> importPaths(). Because of buffering of the input	Eelco Dolstra	1	-2/+2
	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	1	-0/+2

2011-12-16	* Make the import operation through the daemon much more efficient	Eelco Dolstra	1	-17/+14
	(way fewer roundtrips) by allowing the client to send data in bigger chunks. * Some refactoring.
2011-12-16	* Clean up exception handling.	Eelco Dolstra	1	-1/+1

2011-12-15	* Refactoring: move sink/source buffering into separate classes.	Eelco Dolstra	1	-41/+55
	* 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	1	-9/+9
	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	1	-6/+13
	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	1	-0/+3
	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	1	-2/+2
	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	1	-2/+2

2008-06-18	* Some refactoring: put the GC options / results in separate structs.	Eelco Dolstra	1	-0/+2
	* 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	1	-0/+27
	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	1	-1/+3
	* 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	1	-0/+10
	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	1	-0/+71
	* Some refactoring: put the NAR archive integer/string serialisation code in a separate file so it can be reused by the worker protocol implementation.
