2018-07-21	prim_foldlStrict: call forceValue() before value is copied	volth	1	-6/+7
	forceValue() were called after a value is copied effectively forcing only one of the copies keeping another copy not evaluated. This resulted in its evaluation of the same lazy value more than once (the number of hits is not big though)

	Before: $ command time nix-prefetch-url https://cdn.kernel.org/pub/linux/kernel/v4.x/linux-4.17.6.tar.xz 1.19user 1.02system 0:41.96elapsed 5%CPU (0avgtext+0avgdata 182720maxresident)k After: 1.38user 1.05system 0:39.73elapsed 6%CPU (0avgtext+0avgdata 16204maxresident)k Note however that addToStore() can still take a lot of memory (e.g. RemoteStore::addToStore() is constant space, but LocalStore::addToStore() isn't; that's fixed by https://github.com/edolstra/nix/commit/c94b4fc7ee0c7b322a5f3c7ee784063b47a11d98 though). Fixes #1400.
2018-07-11	Fix build on 32-bit systems and macOS	Eelco Dolstra	1	-1/+1

2018-07-05	lib.concatMap and lib.mapAttrs to be builtins	volth	1	-0/+42

2018-07-03	nix-daemon: Respect --store	Eelco Dolstra	1	-3/+7
	For example, this allows you to do run nix-daemon as a non-privileged user: eelco$ NIX_STATE_DIR=~/my-nix/nix/var nix-daemon --store ~/my-nix/ The NIX_STATE_DIR is still needed because settings.nixDaemonSocketFile is not derived from settings.storeUri (and we can't derive it from the store's state directory because we don't want to open the store in the parent process).
2018-07-03	Include cpptoml for build simplicity	Eelco Dolstra	3	-1/+3476

2018-07-03	Add a fromTOML primop	Eelco Dolstra	1	-0/+77
	This is primarily useful for processing Cargo.lock files.
2018-07-03	Store floating point numbers in double precision	Eelco Dolstra	2	-1/+2
	Even on 32-bit systems, Value has enough space to hold a double.

2018-07-02	Merge pull request #2158 from Ma27/improve-search-ux	Eelco Dolstra	1	-10/+20
	search.cc: improve UX for `nix search`
2018-07-02	search.cc: improve UX for `nix search`	Maximilian Bosch	1	-10/+20
	As proposed in #1634 the `nix search` command could use some improvements. Initially 0413aeb35d6ee869a98b6565781c1cf47dc80080 added some basic sorting behavior using `std::map`, a next step would be an improvement of the output. This patch includes the following changes: * Use `$PAGER` for outputs with `RunPager` from `shared.hh`: The same behavior is defined for `nix-env --query`, furthermore it makes searching huge results way easier. * Simplified result blocks: The new output is heavily inspired by the output from `nox`, the first line shows the attribute path and the derivaiton name (`attribute path (derivation name)`) and the description in the second line.
2018-06-23	repl: use `nix build` for building instead of `nix-store -r`	Will Dietz	1	-1/+1
	progress bar!
2018-06-18	progress-bar: re-draw last update if nothing new for 1sec.	Will Dietz	1	-2/+3
	Slightly nicer behavior when updates are somewhat far apart (during a long linking step, perhaps) ensuring things don't appear unresponsive. If we wait the maximum amount for the update, don't bother waiting another 50ms (for rate-limiting purposes) and just check if we should quit. This also ensures we'll notice the request to quit within 1s if quit is signalled but there is not an udpate. (I'm not sure if this happens or not)
2018-06-18	sync.hh: return cv_status instead of dropping it, in case useful.	Will Dietz	1	-2/+2

2018-06-18	Detect redirect loops	Eelco Dolstra	1	-0/+2
	Fixes #2225.

2018-06-16	libstore/gc.cc: ignore ESRCH when reading symlinks in /proc	Symphorien Gibol	1	-1/+1
	readlink is also affected by the problem fixed for regular files in c567afe355df
2018-06-14	Fix optimise-store.cc to skip more paths on macOS	Matthew Justin Bauer	1	-2/+1
	I hate to make this such a large check but the lack of documentation means we really have no idea what's allowed. All of them reported so far have been within ".app/Contents" directories. That appears to be a safe starting point. However, I would not be surprised to also find more paths that are disallowed for instance in .framework or .bundle directories. Fixes #2031 Fixes #2229
2018-06-13	nix: Remove special handling of .drv files	Eelco Dolstra	1	-22/+2
	This makes 'nix copy' and 'nix path-info' work on .drv store paths. Removing special treatment of .drv files seems the most future-proof approach given the possible removal of .drv files in the future. Note that 'nix build' will still build (rather than substitute) .drv paths due to the unfortunate overloading in Store::buildPaths().
2018-06-13	hashDerivationModulo(): Handle chroot stores	Eelco Dolstra	1	-1/+1
	This makes 'nix copy --to /mnt /nix/store/bla.drv' work.
2018-06-13	std::random_shuffle -> std::shuffle	Eelco Dolstra	1	-1/+3
	The former is removed in C++17.
2018-06-12	Move EvalState from the stack to the heap	Eelco Dolstra	5	-46/+46
	EvalState contains a few counters (e.g. nrValues) that increase quickly enough that they end up being interpreted as pointers by the garbage collector. Moving it to the heap makes them invisible to the garbage collector. This reduces the max RSS doing 100 evaluations of nixos.tests.firefox.x86_64-linux.drvPath from 455 MiB to 292 MiB. Note: ideally, allocations would be much further up in the 64-bit address space to reduce the odds of an integer being misinterpreted as a pointer. Maybe we can use some linker magic to move the .bss segment to a higher address.
2018-06-12	GC_malloc -> GC_MALLOC	Eelco Dolstra	2	-9/+3
	This makes it possible to build with -DGC_DEBUG.
2018-06-12	Don't scan for roots in dynamic libraries	Eelco Dolstra	1	-0/+7
	This reduces the risk of object liveness misdetection. For example, Glibc has an internal variable "mp_" that often points to a Boehm object, keeping it alive unnecessarily. Since we don't store any actual roots in global variables, we can just disable data segment scanning. With this, the max RSS doing 100 evaluations of nixos.tests.firefox.x86_64-linux.drvPath went from 718 MiB to 455 MiB.
2018-06-12	Add temporary stats	Eelco Dolstra	2	-1/+28

2018-06-12	Cache parse trees	Eelco Dolstra	2	-2/+19
	This prevents EvalState::resetFileCache() from parsing everything all over again.
2018-06-12	Remove duplicate definition of allocBytes()	Eelco Dolstra	3	-29/+15

2018-06-12	Fix #2162: use getaddrinfo instead of curl to preload NSS	Yorick van Pelt	1	-4/+8

2018-06-11	libstore/gc.cc: ignore ESRCH when reading /proc	Symphorien Gibol	1	-10/+13
	If a process disappears between the time /proc/[pid]/maps is opened and the time it is read, the read() syscall will return ESRCH. This should be ignored.
2018-06-08	use debug instead of printTalkative to avoid spamming hydra queue	AmineChikhaoui	1	-1/+1
	runner logs.

2018-06-01	download.cc: fix readCallback return type (int -> size_t)	Will Dietz	1	-2/+2
	I'm not sure if curl ever asks for enough data at once for truncation to occur but better safe than sorry.
2018-06-01	Improve binary cache upload messages	Eelco Dolstra	2	-5/+15
	Don't say "download" when we mean "upload".

2018-05-30	Make <nix/fetchurl.nix> run in constant memory	Eelco Dolstra	3	-35/+62
	E.g. nix-build --store ~/my-nix/ -E 'import <nix/fetchurl.nix> { url = https://cache.nixos.org/nar/0nwi996rgq4b914qyx0mv2wq4k80hjac7xilikavagw7kxmn2iiv.nar.xz; sha256 = "0nwi996rgq4b914qyx0mv2wq4k80hjac7xilikavagw7kxmn2iiv"; }' now runs in 17 MiB (was 70 MiB), while nix-build --store ~/my-nix/ -E 'import <nix/fetchurl.nix> { url = https://cache.nixos.org/nar/0nwi996rgq4b914qyx0mv2wq4k80hjac7xilikavagw7kxmn2iiv.nar.xz; sha256 = "0d2fxljdih3nc5dqx41hjzic3141ajil94m8kdbpryq569dpsbvb"; unpack = true; }' runs in 17 MiB (was 346 MiB).

2018-05-30	Make HttpBinaryCacheStore::narFromPath() run in constant memory	Eelco Dolstra	3	-3/+116
	This reduces memory consumption of nix copy --from https://cache.nixos.org --to ~/my-nix /nix/store/95cwv4q54dc6giaqv6q6p4r02ia2km35-blender-2.79 from 176 MiB to 82 MiB. (The remaining memory is probably due to xz decompression overhead.) Issue https://github.com/NixOS/nix/issues/1681. Issue https://github.com/NixOS/nix/issues/1969.
