2018-03-06	rand() -> random(), since we use srandom().	Will Dietz
	rand() requires we call srand() instead, but might as well use random().
2018-02-01	Remove obsolete references to manifests	Eelco Dolstra
	Closes #323.
2017-09-14	Show the pid of temporary roots	Eelco Dolstra

2017-09-14	nix-store -q --roots / --gc --print-roots: Print temporary / in-memory roots	Eelco Dolstra
	For example, $ nix-store -q --roots /nix/store/7phd2sav7068nivgvmj2vpm3v47fd27l-patchelf-0.8pre845_0315148 {temp:1} denotes that the path is only being kept alive by a temporary root (i.e. /nix/var/nix/temproots/). Similarly, $ nix-store --gc --print-roots ... {memory:9} -> /nix/store/094gpjn9f15ip17wzxhma4r51nvsj17p-curl-7.53.1 shows that curl is being used by some process.
2017-09-06	Fix abort when the GC thread gets an exception	Eelco Dolstra

2017-09-05	Add automatic garbage collection	Eelco Dolstra
	Nix can now automatically run the garbage collector during builds or while adding paths to the store. The option "min-free = <bytes>" specifies that Nix should run the garbage collector whenever free space in the Nix store drops below <bytes>. It will then delete garbage until "max-free" bytes are available. Garbage collection during builds is asynchronous; running builds are not paused and new builds are not blocked. However, there also is a synchronous GC run prior to the first build/substitution. Currently, no old GC roots are deleted (as in "nix-collect-garbage -d").
2017-09-05	GC: Don't delete own temproots file	Eelco Dolstra
	Since file locks are per-process rather than per-file-descriptor, the garbage collector would always acquire a lock on its own temproots file and conclude that it's stale.
2017-08-31	Rename a few configuration options	Eelco Dolstra
	In particular, drop the "build-" and "gc-" prefixes which are pointless. So now you can say nix build --no-sandbox instead of nix build --no-build-use-sandbox
2017-07-30	Replace Unicode quotes in user-facing strings by ASCII	Jörg Thalheim
	Relevant RFC: NixOS/rfcs#4 $ ag -l \| xargs sed -i -e "/\"/s/’/'/g;/\"/s/‘/'/g"
2017-07-04	Support base-64 hashes	Eelco Dolstra
	Also simplify the Hash API. Fixes #1437.
2017-05-16	Improve progress indicator	Eelco Dolstra

2017-04-24	Remove debug statement	Eelco Dolstra

2017-04-20	Detect lsof	Eelco Dolstra
	Also, don't use lsof on Linux since it's not needed. Fixes #1328.
2017-04-10	Minor cleanup	Eelco Dolstra
	Also, possible fix for #1310 on 32-bit systems.
2017-01-16	AutoCloseDir: Use std::unique_ptr	Eelco Dolstra

2016-12-08	Don't delete .check directories of running builds	Eelco Dolstra
	We need to keep them around for diffoscope.
2016-11-26	Revert "Get rid of unicode quotes (#1140)"	Eelco Dolstra
	This reverts commit f78126bfd6b6c8477fcdbc09b2f98772dbe9a1e7. There really is no need for such a massive change...
2016-11-25	Get rid of unicode quotes (#1140)	Guillaume Maudoux

2016-09-21	printMsg(lvlError, ...) -> printError(...) etc.	Eelco Dolstra

2016-07-21	find-runtime-roots: fold into gc.cc	Shea Levy

2016-07-11	Modernize AutoCloseFD	Shea Levy

2016-06-09	Use O_CLOEXEC in most places	Eelco Dolstra

2016-06-02	LocalStore: Allow the physical and logical store directories to differ	Eelco Dolstra
	This is primarily to subsume the functionality of the copy-from-other-stores substituter. For example, in the NixOS installer, we can now do (assuming we're in the target chroot, and the Nix store of the installation CD is bind-mounted on /tmp/nix): $ nix-build ... --option substituters 'local?state=/tmp/nix/var&real=/tmp/nix/store' However, unlike copy-from-other-stores, this also allows write access to such a store. One application might be fetching substitutes for /nix/store in a situation where the user doesn't have sufficient privileges to create /nix, e.g.: $ NIX_REMOTE="local?state=/home/alice/nix/var&real=/home/alice/nix/store" nix-build ...
2016-06-02	Allow setting the state directory as a store parameter	Eelco Dolstra
	E.g. "local?store=/tmp/store&state=/tmp/var".
2016-06-01	Make the store directory a member variable of Store	Eelco Dolstra

2016-05-04	More GC fixes	Eelco Dolstra

2016-04-25	Fix "path is not in the Nix store" during GC	Eelco Dolstra

2016-04-25	Improved logging abstraction	Eelco Dolstra
	This also gets rid of --log-type, since the nested log type isn't useful in a multi-threaded situation, and nobody cares about the "pretty" log type.
2016-04-21	Fix test failures	Eelco Dolstra

2016-04-19	Move path info caching from BinaryCacheStore to Store	Eelco Dolstra
	Caching path info is generally useful. For instance, it speeds up "nix path-info -rS /run/current-system" (i.e. showing the closure sizes of all paths in the closure of the current system) from 5.6s to 0.15s. This also eliminates some APIs like Store::queryDeriver() and Store::queryReferences().
2016-04-08	Make LocalStore thread-safe	Eelco Dolstra
	Necessary for multi-threaded commands like "nix verify-paths".
2016-02-24	deletePath(): Succeed if path doesn't exist	Eelco Dolstra
	Also makes it robust against concurrent deletions.
2016-02-24	Eliminate reserveSpace flag	Eelco Dolstra

2016-02-11	Move addPermRoot into Store	Eelco Dolstra

2016-02-04	StoreAPI -> Store	Eelco Dolstra
	Calling a class an API is a bit redundant...
2016-02-04	Eliminate the "store" global variable	Eelco Dolstra
	Also, move a few free-standing functions into StoreAPI and Derivation. Also, introduce a non-nullable smart pointer, ref<T>, which is just a wrapper around std::shared_ptr ensuring that the pointer is never null. (For reference-counted values, this is better than passing a "T&", because the latter doesn't maintain the refcount. Usually, the caller will have a shared_ptr keeping the value alive, but that's not always the case, e.g., when passing a reference to a std::thread via std::bind.)
2015-07-17	OCD: foreach -> C++11 ranged for	Eelco Dolstra

2015-06-30	GC: Handle ENOSPC creating/moving to the trash directory	Eelco Dolstra
	Issue #564.
2015-03-06	Fix typos: s/the the/the/	Daniel Hahler

2014-12-12	Ensure we're writing to stderr in the builder	Eelco Dolstra
	http://hydra.nixos.org/build/17862041
2014-11-19	Disable vacuuming the DB after garbage collection	Eelco Dolstra
	Especially in WAL mode on a highly loaded machine, this is not a good idea because it results in a WAL file of approximately the same size ad the database, which apparently cannot be deleted while anybody is accessing it.
2014-11-19	Clean up temp roots in a more C++ way	Eelco Dolstra

2014-11-04	nix-store --gc: Don't warn about missing manifests directory	Eelco Dolstra

2014-10-03	Remove some duplicate code	Eelco Dolstra

2014-08-20	Use proper quotes everywhere	Eelco Dolstra

2014-08-13	Use regular file GC roots if possible	Eelco Dolstra
	This makes hydra-eval-jobs create roots as regular files. See 1c208f2b7ef8ffb5e6d435d703dad83223a67bd6.
2014-08-01	findRoots(): Prevent a call to lstat()	Eelco Dolstra
	This means that getting the roots from /nix/var/nix/.../hydra-roots doesn't need any I/O other than reading the directory.
2014-08-01	Make readDirectory() return inode / file type	Eelco Dolstra

2014-08-01	Allow regular files as GC roots	Eelco Dolstra
	If a root is a regular file, then its name must denote a store path. For instance, the existence of the file /nix/var/nix/gcroots/per-user/eelco/hydra-roots/wzc3cy1wwwd6d0dgxpa77ijr1yp50s6v-libxml2-2.7.7 would cause /nix/store/wzc3cy1wwwd6d0dgxpa77ijr1yp50s6v-libxml2-2.7.7 to be a root. This is useful because it involves less I/O (no need for a readlink() call) and takes up less disk space (the symlink target typically takes up a full disk block, while directory entries are packed more efficiently). This is particularly important for hydra.nixos.org, which has hundreds of thousands of roots, and where reading the roots can take 25 minutes.
2014-03-30	boost::shared_ptr -> std::shared_ptr	Eelco Dolstra
