2015-02-16	Use pivot_root in addition to chroot when possible	Harald van Dijk	1	-0/+1
	chroot only changes the process root directory, not the mount namespace root directory, and it is well-known that any process with chroot capability can break out of a chroot "jail". By using pivot_root as well, and unmounting the original mount namespace root directory, breaking out becomes impossible. Non-root processes typically have no ability to use chroot() anyway, but they can gain that capability through the use of clone() or unshare(). For security reasons, these syscalls are limited in functionality when used inside a normal chroot environment. Using pivot_root() this way does allow those syscalls to be put to their full use.
2015-02-10	Make libsodium an optional dependency	Eelco Dolstra	1	-2/+6

2015-02-04	Use libsodium instead of OpenSSL for binary cache signing	Eelco Dolstra	1	-0/+4
	Sodium's Ed25519 signatures are much shorter than OpenSSL's RSA signatures. Public keys are also much shorter, so they're now specified directly in the nix.conf option ‘binary-cache-public-keys’. The new command ‘nix-store --generate-binary-cache-key’ generates and prints a public and secret key.

2014-01-09	Handle systems where "echo -n" doesn't work	Eelco Dolstra	1	-1/+1

2013-11-25	Expand configure variables before writing config.status	Eelco Dolstra	1	-1/+10
	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	1	-10/+0

2013-11-25	Don't install Libtool	Eelco Dolstra	1	-16/+0

2013-11-25	Don't instantiate Automake makefiles	Eelco Dolstra	1	-25/+1

2013-11-22	Drop the dependency on Automake	Eelco Dolstra	1	-8/+4

2013-11-22	New non-recursive, plain Make-based build system	Eelco Dolstra	1	-0/+1

2013-11-14	Remove nix-setuid-helper	Eelco Dolstra	1	-1/+0
	AFAIK, nobody uses it, it's not maintained, and it has no tests.
2013-08-19	Turn on -Wall	Eelco Dolstra	1	-2/+2

2013-08-07	Run the daemon worker on the same CPU as the client	Eelco Dolstra	1	-0/+4
	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	1	-0/+2

2013-07-12	Add gzip support for channel unpacking	Gergely Risko	1	-1/+1

2013-03-25	makeStoreWritable: Use statvfs instead of /proc/self/mountinfo to find out ↵	Shea Levy	1	-0/+1
	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>

2012-11-15	Disable use of vfork()	Eelco Dolstra	1	-1/+1
	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	1	-0/+4
	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	1	-1/+1

2012-10-03	Rename nix-worker to nix-daemon	Eelco Dolstra	1	-1/+1

2012-08-27	Whitespace	Eelco Dolstra	1	-7/+7

2012-08-01	Use a GNU tar flag to shut up warnings about implausibly old timestamp	Eelco Dolstra	1	-0/+12

2012-07-26	Merge branch 'master' into no-manifests	Eelco Dolstra	1	-0/+17

2012-07-23	Handle platforms that don't support linking to a symlink	Eelco Dolstra	1	-0/+12
	E.g. Darwin doesn't allow this.
2012-07-23	Use lutimes() if available to canonicalise the timestamp of symlinks	Eelco Dolstra	1	-0/+5
	Also use utimes() instead of utime() if lutimes() is not available.
2012-07-09	Add WWW::Curl as a dependency	Eelco Dolstra	1	-0/+11

2012-06-29	Use XZ compression in binary caches	Eelco Dolstra	1	-0/+1
	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	1	-9/+16
	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	1	-1/+1
	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	1	-0/+1

2012-03-19	Fix the optional dependency on OpenSSL	Eelco Dolstra	1	-1/+1
	http://hydra.nixos.org/build/2306540
2012-03-18	Drop the externals directory	Eelco Dolstra	1	-62/+22
	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	1	-4/+8
	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	1	-0/+5

2012-01-05	* Add a -I flag to the Perl bindings to nix-build and some other	Eelco Dolstra	1	-1/+9
	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	1	-2/+2

2012-01-03	* Add a test for nix-channel.	Eelco Dolstra	1	-3/+0
	* Refactor the nix-channel unpacker a bit.
2011-11-21	* Doh.	Eelco Dolstra	1	-1/+1
