2019-10-09 Fix fetchTarball with chroot storesEelco Dolstra1-3/+3
Fixes #2405. (cherry picked from commit 168a8879165dd0deab1a93d343a6003146f37031)
2019-10-09 nix search: remove verbose exampleSam Doshi1-4/+0
(cherry picked from commit 6f6cb5e3880d0c7a1dd2bc13c2e0be8ce0ae9fa1)
2019-10-09 Handle empty sandbox_shellMatthew Bauer1-1/+4
Previously, SANDBOX_SHELL was set to empty when unavailable. This caused issues when actually generating the sandbox. Instead, just set SANDBOX_SHELL when --with-sandbox-shell= is non-empty. Alternative implementation to https://github.com/NixOS/nix/pull/3038. (cherry picked from commit 199e888785bd23073e44e56f6c74b95dc7c10ffa)

2019-10-09 getSourceExpr(): Handle channelsEelco Dolstra1-15/+16

2019-09-03 Support allowSubstitutes attribute in structured attribute derivationsEelco Dolstra6-10/+11
Hopefully fixes #3081 (didn't test).
2019-09-03 Add some noexceptsEelco Dolstra11-18/+19
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).
2019-09-03 Ensure that Callback is called only onceEelco Dolstra5-17/+36
Also, make Callback movable but uncopyable.

2019-08-28 Set maximum name length in NixMatthew Bauer1-0/+4
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
2019-08-28 Don't send certain setting overrides to the daemonEelco Dolstra1-0/+7
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.

2019-08-16 nix-store: fix out of sync protocolzimbatm1-2/+10
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.
2019-08-16 libutil: add SizedSourcezimbatm1-0/+30
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.

Make curl's low speed limit configurable via stalled-download-timeout. Before, this limit was five minutes without receiving a single byte. This is much too long as if the remote end may not have even acknowledged the HTTP request.

2019-08-02 SimplifyEelco Dolstra1-18/+14
With BSD locks we don't have to guard against reading our own temproots.
2019-08-02 Use BSD instead of POSIX file locksEelco Dolstra5-108/+46
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.
2019-08-02 Add a test for auto-GCEelco Dolstra2-2/+10
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.
2019-08-02 Add a post-build-hookregnat6-3/+98
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>
2019-07-30 Don’t rely on EPERMMatthew Bauer1-2/+2
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.

2019-07-25 Use sandbox fallback when cloning fails in builderMatthew Bauer2-1/+14
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.
2019-07-25 Disable CLONE_NEWUSER when it’s unavailableMatthew Bauer2-3/+16
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.

2019-07-10 nix copy: Rename --substitute to --substitute-on-destinationEelco Dolstra1-1/+1
'--substitute' was being shadowed by the regular '--substitute' (the short-hand for '--option substitute true'). Fixes #2983.

2019-07-03 Get BOOST_LDFLAGS from autoconf, fix Ubuntu 16.04 build.Niklas Hambüchen2-2/+2
Our use of boost::coroutine2 depends on -lboost_context, which in turn depends on `-lboost_thread`, which in turn depends on `-lboost_system`. I suspect that this builds on nix only because of low-level hacks like NIX_LDFLAGS. This commit passes the proper linker flags, thus fixing bootstrap builds on non-nix distributions like Ubuntu 16.04. With these changes, I can build Nix on Ubuntu 16.04 using: ./bootstrap.sh ./configure --prefix=$HOME/editline-prefix \ --disable-doc-gen \ CXX=g++-7 \ --with-boost=$HOME/boost-prefix \ EDITLINE_CFLAGS=-I$HOME/editline-prefix/include \ EDITLINE_LIBS=-leditline \ LDFLAGS=-L$HOME/editline-prefix/lib make where * g++-7 comes from gcc-7 from https://launchpad.net/~ubuntu-toolchain-r/+archive/ubuntu/test, * editline 1.14 from https://github.com/troglobit/editline/releases/tag/1.14.0 was installed into `$HOME/editline-prefix` (because Ubuntu 16.04's `editline` is too old to have the function nix uses), * boost 1.66 from https://www.boost.org/doc/libs/1_66_0/more/getting_started/unix-variants.html was installed into $HOME/boost-prefix (because Ubuntu 16.04 only has 1.58)
