2017-09-25Add "nix show-derivation"Eelco Dolstra
This debug command prints a store derivation in JSON format. For example: $ nix show-derivation nixpkgs.hello { "/nix/store/ayjwpwwiyy04nh9z71rsdgd3q7bra7ch-hello-2.10.drv": { "outputs": { "out": { "path": "/nix/store/w5w4v29ql0qwqhczkdxs94ix2lh7ibgs-hello-2.10" } }, "inputSrcs": [ "/nix/store/9krlzvny65gdc8s7kpb6lkx8cd02c25b-default-builder.sh" ], "inputDrvs": { "/nix/store/13839aqdf6x4k3b785rw5f2l7857l6y3-bash-4.4-p12.drv": [ "out" ], "/nix/store/vgdx7fdc7d4iirmnwj2py1nrvr5qwzj7-hello-2.10.tar.gz.drv": [ "out" ], "/nix/store/x3kkd0vsqfflbvwf1055l9mr39bg0ms0-stdenv.drv": [ "out" ] }, "platform": "x86_64-linux", "builder": "/nix/store/qp5fw57d38bd1n07ss4zxh88zg67c3vg-bash-4.4-p12/bin/bash", "args": [ "-e", "/nix/store/9krlzvny65gdc8s7kpb6lkx8cd02c25b-default-builder.sh" ], "env": { "buildInputs": "", "builder": "/nix/store/qp5fw57d38bd1n07ss4zxh88zg67c3vg-bash-4.4-p12/bin/bash", "configureFlags": "", "doCheck": "1", "name": "hello-2.10", "nativeBuildInputs": "", "out": "/nix/store/w5w4v29ql0qwqhczkdxs94ix2lh7ibgs-hello-2.10", "propagatedBuildInputs": "", "propagatedNativeBuildInputs": "", "src": "/nix/store/3x7dwzq014bblazs7kq20p9hyzz0qh8g-hello-2.10.tar.gz", "stdenv": "/nix/store/6zngq1rdh0ans9qyckqimqibgnlvlfrm-stdenv", "system": "x86_64-linux" } } } This removes the need for pp-aterm.

These have a GCC (4.9) that is too old. https://hydra.nixos.org/eval/1391740
2017-09-14RemoteStore: Add option to drop old connections from the poolEelco Dolstra
This is a hack to make hydra-queue-runner free its temproots periodically, thereby ensuring that garbage collection of the corresponding paths is not blocked until the queue runner is restarted. It would be better if temproots could be released earlier than at process exit. I started working on a RAII object returned by functions like addToStore() that releases temproots. However, this would be a pretty massive change so I gave up on it for now.

2017-09-14nix-store -q --roots / --gc --print-roots: Print temporary / in-memory rootsEelco 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.

2017-09-11docker: update to Nix 1.11.14Peter Simons
- Use the latest Nix version 1.11.14. - Attempts to download the Nix installation tarball from http://nixos.org redirect to https these days, which wget doesn't support unless OpenSSL is available. - Use addgroup and adduser commands to create the Nix build users. - Link the Nix profile script into /etc/profile.d, where it's run automatically. - Dropped installation of bash and tar. Neither tool is essential for running Nix. Use the command "docker build -t nix . && docker run -it --rm nix sh -" to build and run the Nix docker container.
2017-09-10Add command "nix why-depends"Eelco Dolstra
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.

Also some refactoring.

2017-09-08ThreadPool: On exception, interrupt the other worker threadsEelco Dolstra
2017-09-08copyStorePath(): Fill in missing narHash regardless of checkSigsEelco Dolstra
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.
2017-09-08nix copy: Don't open the --from store twiceEelco Dolstra
2017-09-08ThreadPool: Improve exception handlingEelco Dolstra
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.

2017-09-08Communicate the structured log FD to buildersEelco Dolstra
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

2017-09-06Fix abort when the GC thread gets an exceptionEelco Dolstra
2017-09-05Add automatic garbage collectionEelco 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").
2017-09-05GC: Don't delete own temproots fileEelco 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.
2017-09-01Abort curl downloads if there is no progress for 5 minutesEelco Dolstra
Maybe this will fix the curl hangs on macOS. (We could also use CURLOPT_TIMEOUT but that seems more of a sledgehammer.)

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.

2017-08-31Call queryMissing() prior to buildingEelco Dolstra
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.
2017-08-31Add an activity for binary cache queriesEelco Dolstra
2017-08-31Rename a few configuration optionsEelco 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

2017-08-29nix run: Add some flags for clearing/keeping the environmentEelco Dolstra
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.
2017-08-29nix run: Allow passing a command to executeEelco Dolstra
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.
