2018-07-03 nix-daemon: Respect --storeEelco Dolstra1-3/+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).

search.cc: improve UX for `nix search`
2018-07-02 search.cc: improve UX for `nix search`Maximilian Bosch1-10/+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.

progress bar!
2018-06-18 progress-bar: re-draw last update if nothing new for 1sec.Will Dietz1-2/+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)

2018-06-14 Fix optimise-store.cc to skip more paths on macOSMatthew Justin Bauer1-2/+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 filesEelco Dolstra1-22/+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 storesEelco Dolstra1-1/+1
This makes 'nix copy --to /mnt /nix/store/bla.drv' work.
2018-06-13 std::random_shuffle -> std::shuffleEelco Dolstra1-1/+3
The former is removed in C++17.
2018-06-12 Move EvalState from the stack to the heapEelco Dolstra5-46/+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_MALLOCEelco Dolstra2-9/+3
This makes it possible to build with -DGC_DEBUG.
2018-06-12 Don't scan for roots in dynamic librariesEelco Dolstra1-0/+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 statsEelco Dolstra2-1/+28
2018-06-12 Cache parse treesEelco Dolstra2-2/+19

2018-06-11 libstore/gc.cc: ignore ESRCH when reading /procSymphorien Gibol1-10/+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.

I'm not sure if curl ever asks for enough data at once for truncation to occur but better safe than sorry.

2018-05-30 Make HttpBinaryCacheStore::narFromPath() run in constant memoryEelco Dolstra3-3/+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.
2018-05-30 Make LocalBinaryCacheStore::narFromPath() run in constant memoryEelco Dolstra6-31/+65
This reduces memory consumption of nix copy --from file://... --to ~/my-nix /nix/store/95cwv4q54dc6giaqv6q6p4r02ia2km35-blender-2.79 from 514 MiB to 18 MiB for an uncompressed binary cache, and from 192 MiB to 53 MiB for a bzipped binary cache. It may also be faster because fetching can happen concurrently with decompression/writing. Continuation of 48662d151bdf4a38670897beacea9d1bd750376a. Issue https://github.com/NixOS/nix/issues/1681.
