2013-06-07	Buffer reads from the substituter	Eelco Dolstra	2	-10/+27
	This greatly reduces the number of system calls.

	Fixes #118.
2013-05-16	Show function names in error messages	Eelco Dolstra	5	-8/+43
	Functions in Nix are anonymous, but if they're assigned to a variable/attribute, we can use the variable/attribute name in error messages, e.g. while evaluating `concatMapStrings' at `/nix/var/nix/profiles/per-user/root/channels/nixos/nixpkgs/pkgs/lib/strings.nix:18:25': ...
2013-05-16	Show which function argument was unexpected	Eelco Dolstra	1	-5/+9
	Fixes #116.
2013-05-16	Shut up a compiler warning	Eelco Dolstra	1	-1/+1

2013-05-10	In trace messages, don't print the output path	Eelco Dolstra	1	-19/+15
	This doesn't work if there is no output named "out". Hydra didn't use it anyway.
2013-05-09	Communicate build timeouts to Hydra	Eelco Dolstra	1	-7/+11

2013-05-09	build-remote.pl: Enforce timeouts locally	Eelco Dolstra	1	-3/+1
	Don't pass --timeout / --max-silent-time to the remote builder. Instead, let the local Nix process terminate the build if it exceeds a timeout. The remote builder will be killed as a side-effect. This gives better error reporting (since the timeout message from the remote side wasn't properly propagated) and handles non-Nix problems like SSH hangs.
2013-05-01	Don't let stderr writes in substituters cause a deadlock	Eelco Dolstra	1	-0/+4

2013-04-26	addAdditionalRoots(): Check each path only once	Eelco Dolstra	1	-2/+2

2013-04-23	Fix --timeout	Eelco Dolstra	1	-38/+25
	I'm not sure if it has ever worked correctly. The line "lastWait = after;" seems to mean that the timer was reset every time a build produced log output. Note that the timeout is now per build, as documented ("the maximum number of seconds that a builder can run").
2013-04-23	Nix daemon: respect build timeout from the client	Eelco Dolstra	2	-4/+5

2013-04-04	Complain if /homeless-shelter exists	Eelco Dolstra	1	-1/+5

2013-03-25	makeStoreWritable: Ask forgiveness, not permission	Shea Levy	1	-2/+2
	It is surprisingly impossible to check if a mountpoint is a bind mount on Linux, and in my previous commit I forgot to check if /nix/store was even a mountpoint at all. statvfs.f_flag is not populated with MS_BIND (and even if it were, my check was wrong in the previous commit). Luckily, the semantics of mount with MS_REMOUNT \| MS_BIND make both checks unnecessary: if /nix/store is not a mountpoint, then mount will fail with EINVAL, and if /nix/store is not a bind-mount, then it will not be made writable. Thus, if /nix/store is not a mountpoint, we fail immediately (since we don't know how to make it writable), and if /nix/store IS a mountpoint but not a bind-mount, we fail at first write (see below for why we can't check and fail immediately). Note that, due to what is IMO buggy behavior in Linux, calling mount with MS_REMOUNT \| MS_BIND on a non-bind readonly mount makes the mountpoint appear writable in two places: In the sixth (but not the 10th!) column of mountinfo, and in the f_flags member of struct statfs. All other syscalls behave as if the mount point were still readonly (at least for Linux 3.9-rc1, but I don't think this has changed recently or is expected to soon). My preferred semantics would be for MS_REMOUNT \| MS_BIND to fail on a non-bind mount, as it doesn't make sense to remount a non bind-mount as a bind mount.
2013-03-25	makeStoreWritable: Use statvfs instead of /proc/self/mountinfo to find out ↵	Shea Levy	1	-21/+12
	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>
2013-03-14	Fix building against Bison 2.6	Eelco Dolstra	2	-6/+4

2013-03-14	Make sure that thunks are restored properly if an exception occurs	Eelco Dolstra	1	-3/+6
	Fixes Hydra bug #67.
2013-03-08	Revert "Prevent config.h from being clobbered"	Eelco Dolstra	16	-104/+177
	This reverts commit 28bba8c44f484eae38e8a15dcec73cfa999156f6.
2013-03-07	Prevent config.h from being clobbered	Eelco Dolstra	16	-177/+104

2013-02-28	Handle systems without lutimes() or lchown()	Eelco Dolstra	1	-1/+1

2013-02-28	Handle symlinks properly	Eelco Dolstra	1	-1/+1
	Now it's really brown paper bag time...
2013-02-27	Handle hard links to other files in the output	Eelco Dolstra	1	-6/+26

2013-02-27	Refactoring: Split off the non-recursive canonicalisePathMetaData()	Eelco Dolstra	3	-37/+52
	Also, change the file mode before changing the owner. This prevents a slight time window in which a setuid binary would be setuid root.
2013-02-26	Security: Don't allow builders to change permissions on files they don't own	Eelco Dolstra	5	-20/+17
	It turns out that in multi-user Nix, a builder may be able to do ln /etc/shadow $out/foo Afterwards, canonicalisePathMetaData() will be applied to $out/foo, causing /etc/shadow's mode to be set to 444 (readable by everybody but writable by nobody). That's obviously Very Bad. Fortunately, this fails in NixOS's default configuration because /nix/store is a bind mount, so "ln" will fail with "Invalid cross-device link". It also fails if hard-link restrictions are enabled, so a workaround is: echo 1 > /proc/sys/fs/protected_hardlinks The solution is to check that all files in $out are owned by the build user. This means that innocuous operations like "ln ${pkgs.foo}/some-file $out/" are now rejected, but that already failed in chroot builds anyway.
2013-02-19	build-remote: Use the --quiet flag	Eelco Dolstra	1	-5/+2
	‘--option verbosity 0’ doesn't actually do anything.
2013-02-19	Add `Settings::nixDaemonSocketFile'.	Ludovic Courtès	5	-10/+14

2013-02-19	Enable chroot support on old glibc versions.	Ludovic Courtès	1	-0/+6

2013-02-08	Make "${./path} ..." evaluate to a string, not a path	Eelco Dolstra	3	-5/+7
	Wacky string coercion semantics caused expressions like exec = "${./my-script} params..."; to evaluate to a path (‘/path/my-script params’), because anti-quotations are desuged to string concatenation: exec = ./my-script + " params..."; By constrast, adding a space at the start would yield a string as expected: exec = " ${./my-script} params..."; Now the first example also evaluates to a string.
2013-02-08	Rename "hash" to "hashString" and handle SHA-1	Eelco Dolstra	1	-19/+9

2013-01-30	Support the colonies	Eelco Dolstra	1	-3/+3

2013-01-23	Only warn about SQLite being busy once	Eelco Dolstra	1	-1/+5
	No need to get annoying.
2013-01-22	Correctly handle missing logs	Eelco Dolstra	1	-1/+3

2013-01-17	Store build logs in /nix/var/log/nix/drvs/<XX>	Eelco Dolstra	2	-30/+37
	...where <XX> is the first two characters of the derivation. Otherwise /nix/var/log/nix/drvs may become so large that we run into all sorts of weird filesystem limits/inefficiences. For instance, ext3/ext4 filesystems will barf with "ext4_dx_add_entry:1551: Directory index full!" once you hit a few million files.
2013-01-05	Delete a left-over trash directory before doing a GC	Eelco Dolstra	1	-1/+4

2013-01-04	Fix "0 store paths deleted" message	Eelco Dolstra	1	-0/+2

2013-01-03	Open the database after removing immutable bits	Eelco Dolstra	1	-1/+1

2013-01-03	Remove tabs	Eelco Dolstra	2	-46/+46

2013-01-03	Clear any immutable bits in the Nix store	Eelco Dolstra	9	-86/+66
	Doing this once makes subsequent operations like garbage collecting more efficient since we don't have to call makeMutable() first.
2013-01-02	If a substitute closure is incomplete, build dependencies, then retry the ↵	Eelco Dolstra	1	-7/+28
	substituter Issue #77.
2013-01-02	Automatically fall back if the references of a substitute are not substitutable	Eelco Dolstra	1	-1/+1
	Fixes #77.
2012-12-29	nix-build: Support talking to old daemons	Eelco Dolstra	1	-1/+10
	Fixes #76.
2012-12-29	Allow mounting a path in a different location in the chroot	Eelco Dolstra	3	-10/+17
	Fixes #24.
2012-12-20	nix-store -q --roots: Respect the gc-keep-outputs/gc-keep-derivations settings	Eelco Dolstra	9	-25/+64
	So if a path is not garbage solely because it's reachable from a root due to the gc-keep-outputs or gc-keep-derivations settings, ‘nix-store -q --roots’ now shows that root.
2012-12-20	Yet another rewrite of the garbage collector	Eelco Dolstra	2	-131/+138
	But this time it's obviously correct! No more segfaults due to infinite recursions for sure, etc. Also, move directories to /nix/store/trash instead of renaming them to /nix/store/bla-gc-<pid>. Then we can just delete /nix/store/trash at the end.
2012-12-19	If gc-keep-derivations is set, only keep the actual deriver	Eelco Dolstra	1	-1/+1
	This prevents zillions of derivations from being kept, and fixes an infinite recursion in the garbage collector (due to an obscure cycle that can occur with fixed-output derivations).
2012-12-19	Kill the build hook rather than shutting it down cleanly	Eelco Dolstra	1	-7/+1
	Waiting for the hook to shut down cleanly sometimes seems to lead to hangs.
2012-12-18	Revert brain fart	Eelco Dolstra	1	-2/+0
	This reverts commit cc511fd65b7b6de9e87e72fb4bed16fc7efeb8b7.
