2017-09-10	Add command "nix why-depends"	Eelco Dolstra	1	-0/+133
	This command shows why a package has another package in its runtime closure. For example, to see why VLC has libdrm.dev in its closure: $ nix why-depends nixpkgs.vlc nixpkgs.libdrm.dev /nix/store/g901z9pcj0n5yy5n6ykxk3qm4ina1d6z-vlc-2.2.5.1: lib/libvlccore.so.8.0.0: …nfig:/nix/store/405lmx6jl8lp0ad1vrr6j498chrqhz8g-libdrm-2.4.75-d… /nix/store/s3nm7kd8hlcg0facn2q1ff2n7wrwdi2l-mesa-noglu-17.0.7-dev: nix-support/propagated-native-build-inputs: …-dev /nix/store/405lmx6jl8lp0ad1vrr6j498chrqhz8g-libdrm-2.4.75-d… Thus, VLC's lib/libvlccore.so.8.0.0 as well as mesa-noglu's nix-support/propagated-native-build-inputs cause the dependency.

2017-09-10	nix build: Only download the requested derivation outputs	Eelco Dolstra	5	-18/+52
	Also some refactoring.

2017-09-08	copyStorePath(): Fill in missing narHash regardless of checkSigs	Eelco Dolstra	1	-5/+1
	I don't remember what the reasoning was here, but security is provided by the signatures, not by whether the hash is provided by the other store.
2017-09-08	nix copy: Don't open the --from store twice	Eelco Dolstra	1	-1/+1

2017-09-08	ThreadPool: Improve exception handling	Eelco Dolstra	2	-24/+53
	In particular, process() won't return as long as there are active items. This prevents work item lambdas from referring to stack frames that no longer exist.

2017-09-08	Communicate the structured log FD to builders	Eelco Dolstra	1	-1/+6
	Since we may use a dedicated file descriptor in the future, this allows us to change it. So builders can do if [[ -n $NIX_LOG_FD ]]; then echo "@nix { message... }" >&$NIX_LOG_FD fi

2017-09-06	Fix abort when the GC thread gets an exception	Eelco Dolstra	1	-13/+21

2017-09-05	Add automatic garbage collection	Eelco Dolstra	6	-1/+127
	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	3	-34/+34
	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.
2017-09-01	Abort curl downloads if there is no progress for 5 minutes	Eelco Dolstra	1	-1/+6
	Maybe this will fix the curl hangs on macOS. (We could also use CURLOPT_TIMEOUT but that seems more of a sledgehammer.)
2017-09-01	Fix verbosity level for nix build --dry-run	Eelco Dolstra	4	-16/+16

2017-09-01	Merge pull request #1545 from trofi/glibc-2.26	Eelco Dolstra	1	-2/+2

2017-08-31	src/libmain/stack.cc: fix 'ucontext' usage on glibc-2.26	Sergei Trofimovich	1	-2/+2
	Build fails as: $ make CXX src/libmain/stack.o src/libmain/stack.cc: In function 'void nix::sigsegvHandler(int, siginfo_t, void)': src/libmain/stack.cc:21:21: error: 'ucontext' was not declared in this scope sp = (char ) ((ucontext ) ctx)->uc_mcontext.gregs[REG_RSP]; ^~~~~~~~ src/libmain/stack.cc:21:21: note: suggested alternative: 'ucontext_t' sp = (char ) ((ucontext ) ctx)->uc_mcontext.gregs[REG_RSP]; ^~~~~~~~ ucontext_t It's caused by upstream rename: https://sourceware.org/git/?p=glibc.git;a=commitdiff;h=251287734e89a52da3db682a8241eb6bccc050c9 which basically changes typedef struct ucontext {} ucontext_t; to typedef struct ucontext_t {} ucontext_t; The change uses ucontext_t.

2017-08-31	Call queryMissing() prior to building	Eelco Dolstra	2	-0/+14
	Without this, substitute info is fetched sequentially, which is superslow. In the old UI (e.g. nix-build), we call printMissing(), which calls queryMissing(), thereby preheating the binary cache cache. But the new UI doesn't do that.
2017-08-31	Add an activity for binary cache queries	Eelco Dolstra	4	-4/+19

2017-08-31	Rename a few configuration options	Eelco Dolstra	16	-104/+113
	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
2017-08-31	More macOS build fixes	Eelco Dolstra	1	-1/+3

2017-08-29	nix edit / log: Operate on a single Installable	Eelco Dolstra	6	-89/+100

2017-08-29	nix search: Warn about cached results	Eelco Dolstra	1	-0/+2

2017-08-29	nix run: Flush the progress bar before starting the command	Eelco Dolstra	5	-19/+28

2017-08-29	nix run: Add some flags for clearing/keeping the environment	Eelco Dolstra	1	-0/+49
	This is useful for testing commands in isolation. For example, $ nix run nixpkgs.geeqie -i -k DISPLAY -k XAUTHORITY -c geeqie runs geeqie in an empty environment, except for $DISPLAY and $XAUTHORITY.
2017-08-29	nix run: Allow passing a command to execute	Eelco Dolstra	3	-3/+19
	E.g. nix run nixpkgs.hello -c hello --greeting Hallo Note that unlike "nix-shell --command", no quoting of arguments is necessary. "-c" (short for "--command") cannot be combined with "--" because they both consume all remaining arguments. But since installables shouldn't start with a dash, this is unlikely to cause problems.
2017-08-29	nix run: Fix chroot execution	Eelco Dolstra	2	-60/+110
	Running "nix run" with a diverted store, e.g. $ nix run --store local?root=/tmp/nix nixpkgs.hello stopped working when Nix became multithreaded, because unshare(CLONE_NEWUSER) doesn't work in multithreaded processes. The obvious solution is to terminate all other threads first, but 1) there is no way to terminate Boehm GC marker threads; and 2) it appears that the kernel has a race where unshare(CLONE_NEWUSER) will still fail for some indeterminate amount of time after joining other threads. So instead, "nix run" will now exec() a single-threaded helper ("nix __run_in_chroot") that performs the actual unshare()/chroot()/exec().
2017-08-29	Hide commands that don't have a description	Eelco Dolstra	1	-2/+5
	These are assumed to be internal.
2017-08-29	readLink(): Handle symlinks in /proc	Eelco Dolstra	1	-4/+5
	Symlinks like /proc/self/exe report a stat() size of 0, so use a buffer of at least PATH_MAX instead.
2017-08-28	Give activities a verbosity level again	Eelco Dolstra	10	-19/+41
	And print them (separately from the progress bar) given sufficient -v flags.
2017-08-28	Don't send progress messages to older clients	Eelco Dolstra	2	-12/+19

2017-08-28	Tunnel progress messages from the daemon to the client	Eelco Dolstra	4	-30/+124
	This makes the progress bar work for non-root users.
2017-08-28	Simplify	Eelco Dolstra	2	-18/+14

2017-08-28	Make TunnelLogger thread-safe	Eelco Dolstra	1	-109/+129
	Now that we use threads in lots of places, it's possible for TunnelLogger::log() to be called asynchronously from other threads than the main loop. So we need to ensure that STDERR_NEXT messages don't clobber other messages.
2017-08-25	Simplify	Eelco Dolstra	3	-29/+56

2017-08-25	Doh	Eelco Dolstra	1	-0/+1

2017-08-25	Allow derivations to update the build phase	Eelco Dolstra	3	-7/+24
	So the progress bar can show [1/0/1 built, 0.0 MiB DL] building hello-2.10 (configuring): checking whether pread is declared without a macro... yes
2017-08-25	Allow activities to be nested	Eelco Dolstra	7	-12/+55
	In particular, this allows more relevant activities ("substituting X") to supersede inferior ones ("downloading X").
2017-08-25	Fix Debian build	Eelco Dolstra	1	-1/+3
	https://hydra.nixos.org/build/59390148
