2019-09-18function-trace: always show the tracezimbatm
If the user invokes nix with --trace-function-calls it means that they want to see the trace.
2019-09-13std::uncaught_exception() -> std::uncaught_exceptions()Eelco Dolstra
The former is deprecated in C++17. Fixes a clang warning.

2019-09-04BinaryCacheStore: Add index-debug-info optionEelco Dolstra
This integrates the functionality of the index-debuginfo program in nixos-channel-scripts to maintain an index of DWARF debuginfo files in a format usable by dwarffs. Thus the debug info index is updated by Hydra rather than by the channel mirroring script. Example usage: $ nix copy --to 'file:///tmp/binary-cache?index-debug-info=true' /nix/store/vr9mhcch3fljzzkjld3kvkggvpq38cva-nix-2.2.2-debug $ cat /tmp/binary-cache/debuginfo/036b210b03bad75ab2d8fc80b7a146f98e7f1ecf.debug {"archive":"../nar/0313h2kdhk4v73xna9ysiksp2v8xrsk5xsw79mmwr3rg7byb4ka8.nar.xz","member":"lib/debug/.build-id/03/6b210b03bad75ab2d8fc80b7a146f98e7f1ecf.debug"} Fixes #3083.

Hopefully fixes #3081 (didn't test).
2019-09-03Add some noexceptsEelco Dolstra
This is to assert that callback functions should never throw (since the context in which they're called may not be able to handle the exception).

Also, make Callback movable but uncopyable.

2019-08-28Set maximum name length in NixMatthew Bauer
Previously we allowed any length of name for Nix derivations. This is bad because different file systems have different max lengths. To make things predictable, I have picked a max. This was done by trying to build this derivation: derivation { name = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"; builder = "/no-such-path"; system = "x86_64-linux"; } Take off one a and it will not lead to file name too long. That ends up being 212 a’s. An even smaller max could be picked if we want to support more file systems. Working backwards, this is why: aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa-${name}.drv.chroot > 255 - 32 - 1 - 4 - 7 = 211
2019-08-28Don't send certain setting overrides to the daemonEelco Dolstra
These are already handled separately. This fixes warnings like warning: ignoring the user-specified setting 'max-jobs', because it is a restricted setting and you are not a trusted user when using the -j flag.

2019-08-16nix-store: fix out of sync protocolzimbatm
If a NAR is already in the store, addToStore doesn't read the source which makes the protocol go out of sync. This happens for example when two client try to nix-copy-closure the same derivation at the same time.
2019-08-16libutil: add SizedSourcezimbatm
Introduce the SizeSource which allows to bound how much data is being read from a source. It also contains a drainAll() function to discard the rest of the source, useful to keep the nix protocol in sync.

2019-08-02nix-store --verify: Don't repair while holding the GC lockEelco Dolstra
2019-08-02SimplifyEelco Dolstra
With BSD locks we don't have to guard against reading our own temproots.
2019-08-02Use BSD instead of POSIX file locksEelco Dolstra
POSIX file locks are essentially incompatible with multithreading. BSD locks have much saner semantics. We need this now that there can be multiple concurrent LocalStore::buildPaths() invocations.
2019-08-02Add a test for auto-GCEelco Dolstra
This currently fails because we're using POSIX file locks. So when the garbage collector opens and closes its own temproots file, it causes the lock to be released and then deleted by another GC instance.
2019-08-02Add a post-build-hookregnat
Passing `--post-build-hook /foo/bar` to a nix-* command will cause `/foo/bar` to be executed after each build with the following environment variables set: DRV_PATH=/nix/store/drv-that-has-been-built.drv OUT_PATHS=/nix/store/...build /nix/store/...build-bin /nix/store/...build-dev This can be useful in particular to upload all the builded artifacts to the cache (including the ones that don't appear in the runtime closure of the final derivation or are built because of IFD). This new feature prints the stderr/stdout output to the `nix-build` and `nix build` client, and the output is printed in a Nix 2 compatible format: [nix]$ ./inst/bin/nix-build ./test.nix these derivations will be built: /nix/store/ishzj9ni17xq4hgrjvlyjkfvm00b0ch9-my-example-derivation.drv building '/nix/store/ishzj9ni17xq4hgrjvlyjkfvm00b0ch9-my-example-derivation.drv'... hello! bye! running post-build-hook '/home/grahamc/projects/github.com/NixOS/nix/post-hook.sh'... post-build-hook: + sleep 1 post-build-hook: + echo 'Signing paths' /nix/store/qr213vjmibrqwnyp5fw678y7whbkqyny-my-example-derivation post-build-hook: Signing paths /nix/store/qr213vjmibrqwnyp5fw678y7whbkqyny-my-example-derivation post-build-hook: + sleep 1 post-build-hook: + echo 'Uploading paths' /nix/store/qr213vjmibrqwnyp5fw678y7whbkqyny-my-example-derivation post-build-hook: Uploading paths /nix/store/qr213vjmibrqwnyp5fw678y7whbkqyny-my-example-derivation post-build-hook: + sleep 1 post-build-hook: + printf 'very important stuff' /nix/store/qr213vjmibrqwnyp5fw678y7whbkqyny-my-example-derivation [nix-shell:~/projects/github.com/NixOS/nix]$ ./inst/bin/nix build -L -f ./test.nix my-example-derivation> hello! my-example-derivation> bye! my-example-derivation (post)> + sleep 1 my-example-derivation (post)> + echo 'Signing paths' /nix/store/c263gzj2kb2609mz8wrbmh53l14wzmfs-my-example-derivation my-example-derivation (post)> Signing paths /nix/store/c263gzj2kb2609mz8wrbmh53l14wzmfs-my-example-derivation my-example-derivation (post)> + sleep 1 my-example-derivation (post)> + echo 'Uploading paths' /nix/store/c263gzj2kb2609mz8wrbmh53l14wzmfs-my-example-derivation my-example-derivation (post)> Uploading paths /nix/store/c263gzj2kb2609mz8wrbmh53l14wzmfs-my-example-derivation my-example-derivation (post)> + sleep 1 my-example-derivation (post)> + printf 'very important stuff' [1 built, 0.0 MiB DL] Co-authored-by: Graham Christensen <graham@grahamc.com> Co-authored-by: Eelco Dolstra <edolstra@gmail.com>

startProcess does not appear to send the exit code to the helper correctly. Not sure why this is, but it is probably safe to just fallback on all sandbox errors.

2019-07-25Use sandbox fallback when cloning fails in builderMatthew Bauer
When sandbox-fallback = true (the default), the Nix builder will fall back to disabled sandbox mode when the kernel doesn’t allow users to set it up. This prevents hard errors from occuring in tricky places, especially the initial installer. To restore the previous behavior, users can set: sandbox-fallback = false in their /etc/nix/nix.conf configuration.
2019-07-25Disable CLONE_NEWUSER when it’s unavailableMatthew Bauer
Some kernels disable "unpriveleged user namespaces". This is unfortunate, but we can still use mount namespaces. Anyway, since each builder has its own nixbld user, we already have most of the benefits of user namespaces.

This is a much simpler fix to the 'error 9 while decompressing xz file' problem than 78fa47a7f08a4cb6ee7061bf0bd86a40e1d6dc91. We just do a ranged HTTP request starting after the data that we previously wrote into the sink. Fixes #2952, #379.
