2012-09-13	Vacuum the SQLite DB after running the garbage collector	Eelco Dolstra

2012-09-13	Delete paths in a component in topologically sorted order	Eelco Dolstra
	The outputs of a derivation can refer to each other (even though they cannot have cycles), so they have to be deleted in the right order. http://hydra.nixos.org/build/3026118
2012-09-13	Disable auto store optimisation for now	Eelco Dolstra
	I've seen operations like "nix-store --import" take much longer on one system. So default to off until I've investigated this a bit further.
2012-09-13	In startBuilder(), only print the new paths we're building	Eelco Dolstra

2012-09-12	Handle gc-keep-outputs and gc-keep-derivations both enabled	Eelco Dolstra
	If the options gc-keep-outputs and gc-keep-derivations are both enabled, you can get a cycle in the liveness graph. There was a hack to handle this, but it didn't work with multiple-output derivations, causing the garbage collector to fail with errors like ‘error: cannot delete path `...' because it is in use by `...'’. The garbage collector now handles strongly connected components in the liveness graph as a unit and decides whether to delete all or none of the paths in an SCC.
2012-09-12	Build hook: Pass the timeout to the remote builder	Eelco Dolstra
	Note that this will only work if the client has a very recent Nix version (post 15e1b2c223494ecb5efefc3ea0e3b926a6b1d7dc), otherwise the --option flag will just be ignored. Fixes #50.
2012-09-11	Fix "non-zero padding" error	Eelco Dolstra
	Probably it's not a good idea to pass a temporary object to StringSource.
2012-09-11	Support building a derivation if some outputs are already valid (non-chroot ↵	Eelco Dolstra
	case) This uses scary hash rewriting. Fixes #21.
2012-09-11	Remove debug line	Eelco Dolstra

2012-09-11	Support building a derivation if some outputs are already valid	Eelco Dolstra
	This handles the chroot and build hook cases, which are easy. Supporting the non-chroot-build case will require more work (hash rewriting!). Issue #21.
2012-09-11	Include config.h before any other header	Eelco Dolstra
	"config.h" must be included first, because otherwise the compiler might not see the right value of _FILE_OFFSET_BITS. We've had this before; see 705868a8a96a10f70e629433cfffc2d5cd2703eb. In this case, GCC would compute a different address for ‘settings.useSubstitutes’ in misc.cc because of the off_t in ‘settings’. Reverts 3854fc9b42d16b810f62b64194b699033b03aaf1. http://hydra.nixos.org/build/3016700
2012-08-27	Fix stupid type error in calling std::max	Eelco Dolstra

2012-08-27	Merge branch 'master' into no-manifests	Eelco Dolstra

2012-08-20	Check if MS_PRIVATE is defined	Eelco Dolstra
	http://hydra.nixos.org/build/2955671
2012-08-20	In the chroot, make all mounted filesystems private	Eelco Dolstra
	This is required on systemd, which mounts filesystems as "shared" subtrees. Changes to shared trees in a private mount namespace are propagated to the outside world, which is bad.
2012-08-20	Don't bind-mount /proc since we mount our own	Eelco Dolstra

2012-08-19	Fix 1755 permission on temporary directories left behind by ‘-K’	Eelco Dolstra

2012-08-07	Don't warn about maximum link count exceeded on 0-byte files	Eelco Dolstra

2012-08-05	Handle amount of disk space saved by hard linking being negative	Eelco Dolstra
	Fixes bogus messages like "currently hard linking saves 17592186044416.00 MiB".
2012-08-05	Fix race condition when two processes create a hard link to a file in .links	Eelco Dolstra
	This is a problem because one process may set the immutable bit before the second process has created its link. Addressed random Hydra failures such as: error: cannot rename `/nix/store/.tmp-link-17397-1804289383' to `/nix/store/rsvzm574rlfip3830ac7kmaa028bzl6h-nixos-0.1pre-git/upstart-interface-version': Operation not permitted
2012-08-05	Fix race condition when two processes create the same link in /nix/store/.links	Eelco Dolstra

2012-08-01	Count bytes freed deleting unused links	Eelco Dolstra

2012-08-01	Drop the block count in the garbage collector	Eelco Dolstra

2012-08-01	nix-store --gc: Make ‘--max-freed 0’ do the right thing	Eelco Dolstra
	That is, delete almost nothing (it will still remove unused links from /nix/store/.links).
2012-08-01	removeUnusedLinks(): Print stats on disk space saved by hard linking	Eelco Dolstra

2012-08-01	Merge branch 'master' into no-manifests	Eelco Dolstra

2012-08-01	Doh	Eelco Dolstra

2012-08-01	Make ‘nix-store --optimise’ interruptible	Eelco Dolstra

2012-08-01	Report substituter errors to clients of the Nix daemon	Eelco Dolstra

2012-07-31	Prevent an injection attack in passing untrusted options to substituters	Eelco Dolstra

2012-07-31	Pass all --option flags to the daemon	Eelco Dolstra

2012-07-31	Add an option ‘build-fallback’ (equivalent to the --fallback flag)	Eelco Dolstra

2012-07-30	Refactor settings processing	Eelco Dolstra
	Put all Nix configuration flags in a Settings object.
2012-07-30	Whitespace	Eelco Dolstra

2012-07-30	Pass configuration settings to the substituters	Eelco Dolstra
	Previously substituters could read nix.conf themselves, but this didn't take --option flags into account.
2012-07-30	Remove unused variables	Eelco Dolstra

2012-07-30	Fix whitespace	Eelco Dolstra

2012-07-27	Let build.cc verify the expected hash of a substituter's output	Eelco Dolstra
	Since SubstitutionGoal::finished() in build.cc computes the hash anyway, we can prevent the inefficiency of computing the hash twice by letting the substituter tell Nix about the expected hash, which can then verify it.
2012-07-27	Remove more tabs	Eelco Dolstra

2012-07-27	Remove trailing whitespace / tabs	Eelco Dolstra

2012-07-26	Fix the substituter tests	Eelco Dolstra

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

2012-07-26	Set permissions on temporary build directories to 0700	Eelco Dolstra
	Fixes #39.
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	Unlink the right file	Eelco Dolstra

2012-07-23	Garbage collect unused links in /nix/store/.links	Eelco Dolstra
	Incremental optimisation requires creating links in /nix/store/.links to all files in the store. However, this means that if we delete a store path, no files are actually deleted because links in /nix/store/.links still exists. So we need to check /nix/store/.links for files with a link count of 1 and delete them.
2012-07-23	Automatically optimise the Nix store when a new path is added	Eelco Dolstra
	Auto-optimisation is enabled by default. It can be turned off by setting auto-optimise-store to false in nix.conf.
2012-07-23	optimiseStore(): Use a content-addressed file store in /nix/store/.links	Eelco Dolstra
	optimiseStore() now creates persistent, content-addressed hard links in /nix/store/.links. For instance, if it encounters a file P with hash H, it will create a hard link P' = /nix/store/.link/<H> to P if P' doesn't already exist; if P' exist, then P is replaced by a hard link to P'. This is better than the previous in-memory map, because it had the tendency to unnecessarily replace hard links with a hard link to whatever happened to be the first file with a given hash it encountered. It also allows on-the-fly, incremental optimisation.
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.
2012-07-18	Use "#pragma once" to prevent repeated header file inclusion	Eelco Dolstra
