2012-08-27	Fix stupid type error in calling std::max	Eelco Dolstra	1	-1/+1

2012-08-27	Merge branch 'master' into no-manifests	Eelco Dolstra	7	-64/+103

2012-08-20	Check if MS_PRIVATE is defined	Eelco Dolstra	1	-1/+1
	http://hydra.nixos.org/build/2955671
2012-08-20	In the chroot, make all mounted filesystems private	Eelco Dolstra	1	-0/+18
	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	1	-2/+2

2012-08-19	Fix 1755 permission on temporary directories left behind by ‘-K’	Eelco Dolstra	1	-4/+4

2012-08-07	Don't warn about maximum link count exceeded on 0-byte files	Eelco Dolstra	1	-2/+4

2012-08-05	Handle amount of disk space saved by hard linking being negative	Eelco Dolstra	1	-2/+2
	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	1	-27/+37
	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	1	-4/+4

2012-08-01	Count bytes freed deleting unused links	Eelco Dolstra	2	-3/+5

2012-08-01	Drop the block count in the garbage collector	Eelco Dolstra	5	-16/+9

2012-08-01	nix-store --gc: Make ‘--max-freed 0’ do the right thing	Eelco Dolstra	3	-6/+5
	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	1	-1/+16

2012-08-01	Merge branch 'master' into no-manifests	Eelco Dolstra	1	-1/+4

2012-08-01	Doh	Eelco Dolstra	1	-1/+2

2012-08-01	Make ‘nix-store --optimise’ interruptible	Eelco Dolstra	1	-0/+2

2012-08-01	Report substituter errors to clients of the Nix daemon	Eelco Dolstra	2	-22/+38

2012-07-31	Prevent an injection attack in passing untrusted options to substituters	Eelco Dolstra	1	-0/+4

2012-07-31	Pass all --option flags to the daemon	Eelco Dolstra	3	-3/+22

2012-07-31	Add an option ‘build-fallback’ (equivalent to the --fallback flag)	Eelco Dolstra	1	-1/+2

2012-07-30	Refactor settings processing	Eelco Dolstra	11	-428/+475
	Put all Nix configuration flags in a Settings object.
2012-07-30	Whitespace	Eelco Dolstra	2	-22/+22

2012-07-30	Pass configuration settings to the substituters	Eelco Dolstra	4	-5/+28
	Previously substituters could read nix.conf themselves, but this didn't take --option flags into account.
2012-07-30	Remove unused variables	Eelco Dolstra	2	-5/+0

2012-07-30	Fix whitespace	Eelco Dolstra	1	-71/+71

2012-07-27	Let build.cc verify the expected hash of a substituter's output	Eelco Dolstra	1	-6/+33
	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	1	-9/+9

2012-07-27	Remove trailing whitespace / tabs	Eelco Dolstra	1	-130/+130

2012-07-26	Fix the substituter tests	Eelco Dolstra	1	-1/+2

2012-07-26	Merge branch 'master' into no-manifests	Eelco Dolstra	13	-160/+199

2012-07-26	Set permissions on temporary build directories to 0700	Eelco Dolstra	1	-1/+2
	Fixes #39.
2012-07-23	Handle platforms that don't support linking to a symlink	Eelco Dolstra	1	-2/+7
	E.g. Darwin doesn't allow this.
2012-07-23	Unlink the right file	Eelco Dolstra	1	-2/+2

2012-07-23	Garbage collect unused links in /nix/store/.links	Eelco Dolstra	2	-0/+39
	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	4	-9/+31
	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	2	-107/+108
	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	1	-9/+16
	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	9	-45/+9

2012-07-18	Merge branch 'master' into no-manifests	Eelco Dolstra	7	-15/+78

2012-07-17	Add function queryPathFromHashPart()	Eelco Dolstra	6	-0/+46
	To implement binary caches efficiently, Hydra needs to be able to map the hash part of a store path (e.g. "gbg...zr7") to the full store path (e.g. "/nix/store/gbg...kzr7-subversion-1.7.5"). (The binary cache mechanism uses hash parts as a key for looking up store paths to ensure privacy.) However, doing a search in the Nix store for /nix/store/<hash>* is expensive since it requires reading the entire directory. queryPathFromHashPart() prevents this by doing a cheap database lookup.
2012-07-17	Return an exit code of 100 for cached failed builds	Eelco Dolstra	1	-0/+1
	Exit code 100 should be returned for all permanent failures. This includes cached failures. Fixes #34.
2012-07-17	Update Nix 1.1 release notes	Eelco Dolstra	1	-0/+3

2012-07-17	Allow disabling log compression	Eelco Dolstra	1	-12/+25

2012-07-11	Update the other substituters	Eelco Dolstra	1	-2/+2

2012-07-11	Replace hasSubstitutes() with querySubstitutablePaths()	Eelco Dolstra	6	-18/+35
	querySubstitutablePaths() takes a set of paths, so this greatly reduces daemon <-> client latency.
2012-07-11	Add a function queryValidPaths()	Eelco Dolstra	6	-0/+34
	queryValidPaths() combines multiple calls to isValidPath() in one. This matters when using the Nix daemon because it reduces latency. For instance, on "nix-env -qas \*" it reduces execution time from 5.7s to 4.7s (which is indistinguishable from the non-daemon case).
2012-07-11	Rename queryValidPaths() to queryAllValidPaths()	Eelco Dolstra	7	-14/+14

2012-07-11	Implement querySubstitutablePathInfos() in the daemon	Eelco Dolstra	6	-47/+42
	Also removed querySubstitutablePathInfo().
2012-07-08	build.cc: Don't use hasSubstitute()	Eelco Dolstra	1	-11/+25
	Instead make a single call to querySubstitutablePathInfo() per derivation output. This is faster and prevents having to implement the "have" function in the binary cache substituter.
