2012-12-20	Yet another rewrite of the garbage collector	Eelco Dolstra
	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
	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
	Waiting for the hook to shut down cleanly sometimes seems to lead to hangs.
2012-12-18	Revert brain fart	Eelco Dolstra
	This reverts commit cc511fd65b7b6de9e87e72fb4bed16fc7efeb8b7.
2012-12-18	Check for potential infinite select() loops when building	Eelco Dolstra

2012-12-13	fix use-after-free bug in mkString(Value&, Symbol&)	Stuart Pernsteiner

2012-12-12	Allow setting the profile location using $NIX_PROFILE	Eelco Dolstra
	Fixes #69.
2012-12-11	On SQLITE_BUSY, wait a random amount of time	Eelco Dolstra
	If all contending processes wait a fixed amount of time (100 ms), there is a good probability that they'll just collide again.
2012-12-04	Tiny optimisation in the filter primop	Eelco Dolstra

2012-12-04	nix-env: Install all outputs of a derivation	Eelco Dolstra
	If you explicitly install a package, presumably you want all of it. So symlink all outputs in the user environment.
2012-12-03	Fix the ‘--prebuilt-only’ flag	Eelco Dolstra

2012-12-03	Whitespace	Eelco Dolstra

2012-11-28	nix-env -q --out-path: Support multiple outputs	Eelco Dolstra
	We now print all output paths of a package, e.g. openssl-1.0.0i bin=/nix/store/gq2mvh0wb9l90djvsagln3aqywqmr6vl-openssl-1.0.0i-bin;man=/nix/store/7zwf5r5hsdarl3n86dasvb4chm2xzw9n-openssl-1.0.0i-man;/nix/store/cj7xvk7fjp9q887359j75pw3pzjfmqf1-openssl-1.0.0i or (in XML mode) <item attrPath="openssl" name="openssl-1.0.0i" system="x86_64-linux"> <output name="bin" path="/nix/store/gq2mvh0wb9l90djvsagln3aqywqmr6vl-openssl-1.0.0i-bin" /> <output name="man" path="/nix/store/7zwf5r5hsdarl3n86dasvb4chm2xzw9n-openssl-1.0.0i-man" /> <output name="out" path="/nix/store/cj7xvk7fjp9q887359j75pw3pzjfmqf1-openssl-1.0.0i" /> </item>
2012-11-27	Optionally ignore null-valued derivation attributes	Eelco Dolstra
	This allows adding attributes like attr = if stdenv.system == "bla" then something else null; without changing the resulting derivation on non-<bla> platforms. We once considered adding a special "ignore" value for this purpose, but using null seems more elegant.
2012-11-27	Add builtin constants ‘langVersion’ and ‘nixVersion’	Eelco Dolstra
	The integer constant ‘langVersion’ denotes the current language version. It gets increased every time a language feature is added/changed/removed. It's currently 1. The string constant ‘nixVersion’ contains the current Nix version, e.g. "1.2pre2980_9de6bc5".
2012-11-26	queryMissing(): Handle partially valid derivations	Eelco Dolstra

2012-11-26	nix-instantiate: Fix read-only evaluation	Eelco Dolstra

2012-11-26	Only substitute wanted outputs of a derivation	Eelco Dolstra
	If a derivation has multiple outputs, then we only want to download those outputs that are actuallty needed. So if we do "nix-build -A openssl.man", then only the "man" output should be downloaded. Likewise if another package depends on ${openssl.man}. The tricky part is that different derivations can depend on different outputs of a given derivation, so we may need to restart the corresponding derivation goal if that happens.
2012-11-26	Make "nix-build -A <derivation>.<output>" do the right thing	Eelco Dolstra
	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.
2012-11-20	nix-store -r: Add ‘--ignore-unknown’ flag	Eelco Dolstra
	This flag causes paths that do not have a known substitute to be quietly ignored. This is mostly useful for Charon, allowing it to speed up deployment by letting a machine use substitutes for all substitutable paths, instead of uploading them. The latter is frequently faster, e.g. if the target machine has a fast Internet connection while the source machine is on a slow ADSL line.
2012-11-19	nix-store -r: Don't quietly ignore missing paths	Eelco Dolstra

2012-11-15	Revert "prim_toPath: Actually make the string a path"	Eelco Dolstra
	This reverts commit 2980d1fba97069805c3649c5d99d0356bce6c303. It causes a regression in NixOS evaluation: string `/nix/store/ya3s5gmj3b28170fpbjhgsk8wzymkpa1-pommed-1.39/etc/pommed.conf' cannot refer to other paths
2012-11-15	Disable use of vfork()	Eelco Dolstra
	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.
2012-11-15	Don't use std::cerr in a few places	Eelco Dolstra
	Slightly scared of using std::cerr in a vforked process...
2012-11-15	Add some debug code	Eelco Dolstra

2012-11-09	Use vfork() instead of fork() if available	Eelco Dolstra
	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 definition of non-existant function	Eelco Dolstra

2012-11-09	Remove some redundant close() calls	Eelco Dolstra
	They are unnecessary because we set the close-on-exec flag.
2012-11-09	Remove the quickExit function	Eelco Dolstra

2012-11-09	Remove a Darwin hack that should no longer be needed	Eelco Dolstra

2012-11-09	Fix a segfault when auto-calling a "a@{...}" function	Eelco Dolstra
	Since the called function can return its argument attribute set (e.g. "a"), the latter should not be allocated on the stack. Reported by Shea.
2012-11-09	Don't start copy-from-other-stores if $NIX_OTHER_STORES is unset	Eelco Dolstra
	Slight optimisation.
2012-11-09	Remove unnecessary call to closeMostFDs()	Eelco Dolstra
	We have close-on-exec on all FDs now, and there is no security risk in passing open FDs to substituters anyway.
2012-11-06	canonicalizePathMetaData: Fall-back to utimes if lutimes fails due to ENOSYS	Shea Levy

2012-10-23	If hashes do not match, print them in base-32 for SHA-1/SHA-256	Eelco Dolstra
	Fixes #57.
2012-10-23	prim_toPath: Actually make the string a path	Shea Levy

2012-10-11	Shorten the names of temporary build directories	Eelco Dolstra

2012-10-04	getDerivation(): Don't always quietly ignore assertion failure	Eelco Dolstra
	Ignoring assertion failures makes some sense for nix-env -qa, but not for nix-instantiate/nix-build or hydra-eval-jobs.
2012-10-04	XML writer: flush after newlines	Eelco Dolstra
	This is useful for hydra-eval-jobs.
2012-10-04	nix-store --verify: Continue on errors	Eelco Dolstra

2012-10-04	Fix regular expression	Eelco Dolstra
	http://hydra.nixos.org/build/3123177
2012-10-03	Rename nix-worker to nix-daemon	Eelco Dolstra

2012-10-03	Drop support for running nix-worker in "slave" mode	Eelco Dolstra
	AFAIK nobody uses this, setuid binaries are evil, and there is no good reason why people can't just run the daemon.
2012-10-03	Remove bin2c	Eelco Dolstra

2012-10-03	When ‘--help’ is given, just run ‘man’ to show the manual page	Eelco Dolstra
	I.e. do what git does. I'm too lazy to keep the builtin help text up to date :-) Also add ‘--help’ to various commands that lacked it (e.g. nix-collect-garbage).
2012-10-03	nix-env: Support ‘--repair’ flag	Eelco Dolstra

2012-10-03	Add a ‘--repair’ flag to nix-instantiate	Eelco Dolstra
	This allows repairing corrupted derivations and other source files.
2012-10-03	Handle repairing paths that are in build-chroot-dirs	Eelco Dolstra

2012-10-03	When repairing a derivation, check and repair the entire output closure	Eelco Dolstra
	If we find a corrupted path in the output closure, we rebuild the derivation that produced that particular path.
2012-10-02	Add a --repair flag to ‘nix-store -r’ to repair derivation outputs	Eelco Dolstra
	With this flag, if any valid derivation output is missing or corrupt, it will be recreated by using a substitute if available, or by rebuilding the derivation. The latter may use hash rewriting if chroots are not available.
