2014-12-12	Ensure we're writing to stderr in the builder	Eelco Dolstra	1	-12/+13

2014-12-12	Doh	Eelco Dolstra	1	-2/+2

2014-12-10	Don't do vfork in conjunction with setuid	Eelco Dolstra	1	-0/+3

2014-12-10	Use vfork	Eelco Dolstra	1	-8/+23

2014-12-10	Revert "Use posix_spawn to run the pager"	Eelco Dolstra	1	-8/+2
	This reverts commit d34d2b2bbf784c0bb420a50905af25e02c6e4989.
2014-12-05	Use posix_spawn to run the pager	Eelco Dolstra	1	-2/+8
	In low memory environments, "nix-env -qa" failed because the fork to run the pager hit the kernel's overcommit limits. Using posix_spawn gets around this. (Actually, you have to use posix_spawn with the undocumented POSIX_SPAWN_USEVFORK flag, otherwise it just uses fork/exec...)
2014-11-19	nix-daemon: Call exit(), not _exit()	Eelco Dolstra	1	-2/+5
	This was preventing destructors from running. In particular, it was preventing the deletion of the temproot file for each worker process. It may also have been responsible for the excessive WAL growth on Hydra (due to the SQLite database not being closed properly). Apparently broken by accident in 8e9140cfdef9dbd1eb61e4c75c91d452ab5e4a74.
2014-10-03	Remove some duplicate code	Eelco Dolstra	1	-0/+10

2014-10-03	createDirs(): Handle ‘path’ being a symlink	Eelco Dolstra	1	-0/+3
	In particular, this fixes "nix-build -o /tmp/result" on Mac OS X (where /tmp is a symlink).
2014-09-19	Remove bogus comment	Eelco Dolstra	1	-1/+0

2014-08-21	Use PR_SET_PDEATHSIG to ensure child cleanup	Eelco Dolstra	1	-1/+10

2014-08-20	Use proper quotes everywhere	Eelco Dolstra	1	-26/+26

2014-08-20	Add some color	Eelco Dolstra	1	-0/+35

2014-08-20	nix-store -l: Automatically pipe output into $PAGER	Eelco Dolstra	1	-2/+2

2014-08-04	Get rid of "killing <pid>" message for unused build hooks	Eelco Dolstra	1	-2/+3

2014-08-01	Call commonChildInit() before doing chroot init	Eelco Dolstra	1	-8/+10
	This ensures that daemon clients see error messages from the chroot setup.
2014-08-01	Eliminate redundant copy	Eelco Dolstra	1	-1/+1

2014-08-01	Make readDirectory() return inode / file type	Eelco Dolstra	1	-8/+7

2014-07-31	Restore default SIGPIPE handler before invoking ‘man’	Eelco Dolstra	1	-0/+10
	Fixes NixOS/nixpkgs#3410.
2014-07-23	nix-daemon: Simplify stderr handling	Eelco Dolstra	1	-0/+1

2014-07-23	startProcess: Make writing error messages from the child more robust	Eelco Dolstra	1	-2/+4

2014-07-10	Fix broken Pid constructor	Eelco Dolstra	1	-5/+2

2014-07-10	Refactoring: Move all fork handling into a higher-order function	Eelco Dolstra	1	-54/+53
	C++11 lambdas ftw.
2014-07-10	Remove maybeVfork	Eelco Dolstra	1	-8/+1

2014-05-21	nix-store -l: Fetch build logs from the Internet	Eelco Dolstra	1	-1/+1
	If a build log is not available locally, then ‘nix-store -l’ will now try to download it from the servers listed in the ‘log-servers’ option in nix.conf. For instance, if you have: log-servers = http://hydra.nixos.org/log then it will try to get logs from http://hydra.nixos.org/log/<base name of the store path>. So you can do things like: $ nix-store -l $(which xterm) and get a log even if xterm wasn't built locally.
2014-04-08	If a .drv cannot be parsed, show its path	Eelco Dolstra	1	-1/+1
	Otherwise you just get ‘expected string `Derive(['’ which isn't very helpful.
2014-03-28	Don't interpret strings as format strings	Eelco Dolstra	1	-13/+13
	Ludo reported this error: unexpected Nix daemon error: boost::too_few_args: format-string refered to more arguments than were passed coming from this line: printMsg(lvlError, run.program + ": " + string(err, 0, p)); The problem here is that the string ends up implicitly converted to a Boost format() object, so % characters are treated specially. I always assumed (wrongly) that strings are converted to a format object that outputs the string as-is. Since this assumption appears in several places that may be hard to grep for, I've added some C++ type hackery to ensures that the right thing happens. So you don't have to worry about % in statements like printMsg(lvlError, "foo: " + s); or throw Error("foo: " + s);
2014-02-27	Set up a minimal /dev in chroots	Eelco Dolstra	1	-0/+7
	Not bind-mounting the /dev from the host also solves the problem with /dev/shm being a symlink to something not in the chroot.
2014-02-26	Remove another unused function	Eelco Dolstra	1	-19/+0

2014-02-26	Remove unused function	Eelco Dolstra	1	-28/+0

2013-11-14	Remove nix-setuid-helper	Eelco Dolstra	1	-13/+0
	AFAIK, nobody uses it, it's not maintained, and it has no tests.
2013-08-26	Fix typos, especially those that end up in the Nix manual	Ivan Kozik	1	-2/+2

2013-08-19	Store Nix integers as longs	Eelco Dolstra	1	-8/+0
	So on 64-bit systems, integers are now 64-bit. Fixes #158.
2013-07-30	killUser: Don't let the child kill itself on Apple	Shea Levy	1	-0/+13
	The kill(2) in Apple's libc follows POSIX semantics, which means that kill(-1, SIGKILL) will kill the calling process too. Since nix has no way to distinguish between the process successfully killing everything and the process being killed by a rogue builder in that case, it can't safely conclude that killUser was successful. Luckily, the actual kill syscall takes a parameter that determines whether POSIX semantics are followed, so we can call that syscall directly and avoid the issue on Apple.

2013-07-12	Garbage collector: Don't follow symlinks arbitrarily	Eelco Dolstra	1	-0/+9
	Only indirect roots (symlinks to symlinks to the Nix store) are now supported.
2013-06-20	Don't keep "disabled" substituters running	Eelco Dolstra	1	-0/+1
	For instance, it's pointless to keep copy-from-other-stores running if there are no other stores, or download-using-manifests if there are no manifests. This also speeds things up because we don't send queries to those substituters.
2013-01-03	Remove tabs	Eelco Dolstra	1	-44/+44

2013-01-03	Clear any immutable bits in the Nix store	Eelco Dolstra	1	-3/+0
	Doing this once makes subsequent operations like garbage collecting more efficient since we don't have to call makeMutable() first.
2012-11-26	Make "nix-build -A <derivation>.<output>" do the right thing	Eelco Dolstra	1	-1/+13
	For example, given a derivation with outputs "out", "man" and "bin": $ nix-build -A pkg produces ./result pointing to the "out" output; $ nix-build -A pkg.man produces ./result-man pointing to the "man" output; $ nix-build -A pkg.all produces ./result, ./result-man and ./result-bin; $ nix-build -A pkg.all -A pkg2 produces ./result, ./result-man, ./result-bin and ./result-2.
2012-11-15	Don't use std::cerr in a few places	Eelco Dolstra	1	-15/+20
	Slightly scared of using std::cerr in a vforked process...
2012-11-15	Add some debug code	Eelco Dolstra	1	-1/+1

2012-11-09	Use vfork() instead of fork() if available	Eelco Dolstra	1	-3/+11
	Hopefully this reduces the chance of hitting ‘unable to fork: Cannot allocate memory’ errors. vfork() is used for everything except starting builders.
2012-11-09	Remove some redundant close() calls	Eelco Dolstra	1	-10/+8
	They are unnecessary because we set the close-on-exec flag.
2012-11-09	Remove the quickExit function	Eelco Dolstra	1	-9/+3

2012-09-28	Handle octal escapes in /proc/self/mountinfo	Eelco Dolstra	1	-0/+15

2012-09-19	Templatise tokenizeString()	Eelco Dolstra	1	-2/+5

2012-08-27	Merge branch 'master' into no-manifests	Eelco Dolstra	1	-15/+10

2012-08-20	In the chroot, make all mounted filesystems private	Eelco Dolstra	1	-2/+2
	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.
2012-08-01	Drop the block count in the garbage collector	Eelco Dolstra	1	-13/+8
