2017-09-05 Add automatic garbage collectionEelco Dolstra6-1/+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 fileEelco Dolstra3-34/+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 minutesEelco Dolstra1-1/+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-runEelco Dolstra4-16/+16
2017-08-31 src/libmain/stack.cc: fix 'ucontext' usage on glibc-2.26Sergei Trofimovich1-2/+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 buildingEelco Dolstra2-0/+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 queriesEelco Dolstra4-4/+19
2017-08-31 Rename a few configuration optionsEelco Dolstra16-104/+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

2017-08-29 nix edit / log: Operate on a single InstallableEelco Dolstra6-89/+100
2017-08-29 nix search: Warn about cached resultsEelco Dolstra1-0/+2
2017-08-29 nix run: Flush the progress bar before starting the commandEelco Dolstra5-19/+28
2017-08-29 nix run: Add some flags for clearing/keeping the environmentEelco Dolstra1-0/+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 executeEelco Dolstra3-3/+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 executionEelco Dolstra2-60/+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 descriptionEelco Dolstra1-2/+5
These are assumed to be internal.
2017-08-29 readLink(): Handle symlinks in /procEelco Dolstra1-4/+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 againEelco Dolstra10-19/+41
And print them (separately from the progress bar) given sufficient -v flags.
2017-08-28 Don't send progress messages to older clientsEelco Dolstra2-12/+19
2017-08-28 Tunnel progress messages from the daemon to the clientEelco Dolstra4-30/+124
This makes the progress bar work for non-root users.
2017-08-28 SimplifyEelco Dolstra2-18/+14
2017-08-28 Make TunnelLogger thread-safeEelco Dolstra1-109/+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 SimplifyEelco Dolstra3-29/+56
2017-08-25 DohEelco Dolstra1-0/+1
2017-08-25 Allow derivations to update the build phaseEelco Dolstra3-7/+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 nestedEelco Dolstra7-12/+55
In particular, this allows more relevant activities ("substituting X") to supersede inferior ones ("downloading X").
2017-08-25 Fix Debian buildEelco Dolstra1-1/+3

2017-08-25 TypoEelco Dolstra1-1/+1
2017-08-25 Restore activity metadataEelco Dolstra4-20/+36
This allows the progress bar to display "building perl-5.22.3" instead of "building /nix/store/<hash>-perl-5.22.3.drv".
2017-08-21 Clean up JSON constructionEelco Dolstra1-3/+18
2017-08-21 Allow builders to create activitiesEelco Dolstra4-7/+76
Actually, currently they can only create download activities. Thus, downloads by builtins.fetchurl show up in the progress bar.
2017-08-21 Remove debug lineEelco Dolstra1-2/+0
2017-08-21 Disallow accidental copy constructionEelco Dolstra1-0/+2
2017-08-19 Remove nix-mode.el from Nix.Matthew Bauer7-229/+7
This removes the file nix-mode.el from Nix. The file is now available within the repository https://github.com/NixOS/nix-mode. Fixes #662 Fixes #1040 Fixes #1054 Fixes #1055 Closes #1119 Fixes #1419 NOTE: all of the above should be fixed within NixOS/nix-mode. If one of those hasn’t please reopen within NixOS/nix-mode and not within NixOS/nix.

2017-08-18 Remove unused decodeOctalEscapedAndy Wingo2-21/+0
Besides being unused, this function has a bug that it will incorrectly decode the path component Ubuntu\04016.04.2\040LTS\040amd64 as "Ubuntu.04.2 LTS amd64" instead of "Ubuntu 16.04.2 LTS amd64".

2017-08-16 Progress indicator: Unify "copying" and "substituting"Eelco Dolstra4-87/+24
They're the same thing after all. Example: $ nix build --store local?root=/tmp/nix nixpkgs.firefox-unwrapped [0/1 built, 49/98 copied, 16.3/92.8 MiB DL, 55.8/309.2 MiB copied] downloading 'https://cache.nixos.org/nar/0pl9li1jigcj2dany47hpmn0r3r48wc4nz48v5mqhh426lgz3bz6.nar.xz'
2017-08-16 Improve substitution progress indicatorEelco Dolstra5-86/+93
E.g. $ nix build --store local?root=/tmp/nix nixpkgs.firefox-unwrapped [0/1 built, 1/97/98 fetched, 65.8/92.8 MiB DL, 203.2/309.2 MiB copied] downloading 'https://cache.nixos.org/nar/1czm9fk0svacy4h6a3fzkpafi4f7a9gml36kk8cq1igaghbspg3k.nar.xz'
2017-08-16 nix copy: Improve progress indicatorEelco Dolstra4-38/+111
It now shows the amount of data copied: [8/1038 copied, 160.4/1590.9 MiB copied] copying path '...'
