2013-11-25	Expand configure variables before writing config.status	Eelco Dolstra
	This way, we can use config.status for generating scripts/* (without ending up with lines like "#! /usr/bin/perl -I${libexecdir}/...").
2013-11-25	Remove obsolete setting of $CC_FOR_BUILD	Eelco Dolstra

2013-11-25	Don't install Libtool	Eelco Dolstra

2013-11-25	Don't instantiate Automake makefiles	Eelco Dolstra

2013-11-22	Drop the dependency on Automake	Eelco Dolstra

2013-11-22	New non-recursive, plain Make-based build system	Eelco Dolstra

2013-11-14	Remove nix-setuid-helper	Eelco Dolstra
	AFAIK, nobody uses it, it's not maintained, and it has no tests.
2013-08-19	Turn on -Wall	Eelco Dolstra

2013-08-07	Run the daemon worker on the same CPU as the client	Eelco Dolstra
	On a system with multiple CPUs, running Nix operations through the daemon is significantly slower than "direct" mode: $ NIX_REMOTE= nix-instantiate '<nixos>' -A system real 0m0.974s user 0m0.875s sys 0m0.088s $ NIX_REMOTE=daemon nix-instantiate '<nixos>' -A system real 0m2.118s user 0m1.463s sys 0m0.218s The main reason seems to be that the client and the worker get moved to a different CPU after every call to the worker. This patch adds a hack to lock them to the same CPU. With this, the overhead of going through the daemon is very small: $ NIX_REMOTE=daemon nix-instantiate '<nixos>' -A system real 0m1.074s user 0m0.809s sys 0m0.098s
2013-08-06	Set the default GCC optimisation level to -O3	Eelco Dolstra

2013-07-12	Add gzip support for channel unpacking	Gergely Risko

2013-03-25	makeStoreWritable: Use statvfs instead of /proc/self/mountinfo to find out ↵	Shea Levy
	if /nix/store is a read-only bind mount /nix/store could be a read-only bind mount even if it is / in its own filesystem, so checking the 4th field in mountinfo is insufficient. Signed-off-by: Shea Levy <shea@shealevy.com>
2013-01-02	Urgggh	Eelco Dolstra
	http://hydra.nixos.org/build/3661100
2012-11-15	Disable use of vfork()	Eelco Dolstra
	vfork() is just too weird. For instance, in this build: http://hydra.nixos.org/build/3330487 the value fromHook.writeSide becomes corrupted in the parent, even though the child only reads from it. At -O0 the problem goes away. Probably the child is overriding some spilled temporary variable. If I get bored I may implement using posix_spawn() instead.
2012-11-09	Use vfork() instead of fork() if available	Eelco Dolstra
	Hopefully this reduces the chance of hitting ‘unable to fork: Cannot allocate memory’ errors. vfork() is used for everything except starting builders.
2012-10-10	Out-of-tree building of perl modules.	Mats Erik Andersson

2012-10-03	Rename nix-worker to nix-daemon	Eelco Dolstra

2012-10-03	Remove bin2c	Eelco Dolstra

2012-09-14	Test whether GNU tar understands --warning=no-timestamp	Eelco Dolstra
	http://hydra.nixos.org/build/3031618
2012-08-27	Whitespace	Eelco Dolstra

2012-08-01	Use a GNU tar flag to shut up warnings about implausibly old timestamp	Eelco Dolstra

2012-07-26	Merge branch 'master' into no-manifests	Eelco Dolstra

2012-07-23	Handle platforms that don't support linking to a symlink	Eelco Dolstra
	E.g. Darwin doesn't allow this.
2012-07-23	Use lutimes() if available to canonicalise the timestamp of symlinks	Eelco Dolstra
	Also use utimes() instead of utime() if lutimes() is not available.
2012-07-09	Add WWW::Curl as a dependency	Eelco Dolstra

2012-06-29	Use XZ compression in binary caches	Eelco Dolstra
	XZ compresses significantly better than bzip2. Here are the compression ratios and execution times (using 4 cores in parallel) on my /var/run/current-system (3.1 GiB): bzip2: total compressed size 849.56 MiB, 30.8% [2m08] xz -6: total compressed size 641.84 MiB, 23.4% [6m53] xz -7: total compressed size 621.82 MiB, 22.6% [7m19] xz -8: total compressed size 599.33 MiB, 21.8% [7m18] xz -9: total compressed size 588.18 MiB, 21.4% [7m40] Note that compression takes much longer. More importantly, however, decompression is much faster: bzip2: 1m47.274s xz -6: 0m55.446s xz -7: 0m54.119s xz -8: 0m52.388s xz -9: 0m51.842s The only downside to using -9 is that decompression takes a fair amount (~65 MB) of memory.
2012-05-10	Support building with the Perl XS bindings disabled	Eelco Dolstra
	Since the Perl bindings require shared libraries, this is required on platforms such as Cygwin where we do a static build.
2012-05-04	Require SQLite >= 3.6.19	Eelco Dolstra
	Nix needs SQLite's foreign key constraint feature, which was introduced in 3.6.19. Without it, the database won't be cleaned up correctly when paths are deleted. See e.g. http://hydra.nixos.org/build/2494142.
2012-04-13	If "pv" is available at compile time, hard-code its path	Eelco Dolstra

2012-03-19	Fix the optional dependency on OpenSSL	Eelco Dolstra
	http://hydra.nixos.org/build/2306540
2012-03-18	Drop the externals directory	Eelco Dolstra
	Nix now requires SQLite and bzip2 to be pre-installed. SQLite is detected using pkg-config. We required DBD::SQLite anyway, so depending on SQLite is not a big problem. The --with-bzip2, --with-openssl and --with-sqlite flags are gone.
2012-02-15	On Linux, make the Nix store really read-only by using the immutable bit	Eelco Dolstra
	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.
2012-01-11	* Figure out the extension of dynamic libraries; don't hard-code .so.	Eelco Dolstra

2012-01-05	* Add a -I flag to the Perl bindings to nix-build and some other	Eelco Dolstra
	scripts. * Include the version and architecture in the -I flag so that there is at least a chance that a Nix binary built for one Perl version will run on another version.
2012-01-04	* Let --disable-gc work.	Eelco Dolstra

2012-01-03	* Add a test for nix-channel.	Eelco Dolstra
	* Refactor the nix-channel unpacker a bit.
2011-11-21	* Doh.	Eelco Dolstra

2011-11-21	* Put back the "sys_name" variable which got removed somewhere. This	Eelco Dolstra
	broke building on Cygwin and Solaris.
2011-11-21	* Escape the [ and ] characters in the sed call, otherwise autoconf	Eelco Dolstra
	will eat them.
2011-11-20	* "sed" on FreeBSD doesn't know the "+" operator.	Eelco Dolstra

2011-11-18	* In the platform, canonicalise "amd64" to "x86_64". FreeBSD 8.2's	Eelco Dolstra
	uname reports amd64. * Drop the FreeBSD version number, e.g. "i686-freebsd" instead of "i686-freebsd8.2".
2011-11-16	configure: Change i*86 to i686 as has always been done.	Ludovic Courtès

2011-11-16	configure: Rely on `AC_CANONICAL_HOST' to determine the Nix system name.	Ludovic Courtès
	This should be more robust and also plays better with cross-compilation---it uses the host name, instead of using the build name.
2011-11-07	* Boldly make SQLite WAL mode the default again. Hopefully the	Eelco Dolstra
	intermittent problems are gone by now. WAL mode is preferrable because it does way fewer fsyncs.
2011-10-10	* Install NixManifest.pm, NixConfig.pm and GeneratePatches.pm under	Eelco Dolstra
	the Nix:: namespace.
