2019-06-25 Add "warning" verbosity levelEelco Dolstra2-1/+3
This ensures that "nix" shows warnings. Previously these were hidden because they were at "info" level. (cherry picked from commit 615a9d031d22a6aee64f8511e15685e47b6f8796)
2019-06-24 Fix 'error 9 while decompressing xz file'Eelco Dolstra2-0/+40
Once we've started writing data to a Sink, we can't restart a download request, because then we end up writing duplicate data to the Sink. Therefore we shouldn't handle retries in Downloader but at a higher level (in particular, in copyStorePath()). Fixes #2952. (cherry picked from commit a67cf5a3585c41dd9f219a2c7aa9cf67fa69520b)
2019-05-15 Merge pull request #2810 from NixOS/print-build-logsEelco Dolstra1-0/+1
nix: Add --print-build-logs flag
2019-05-15 nix: Add --print-build-logs flagEelco Dolstra1-0/+1
This causes 'nix' to print build log output to stderr rather than showing the last log line in the progress bar. Log lines are prefixed by the name of the derivation (minus the version string), e.g. binutils> make[1]: Leaving directory '/build/binutils-2.31.1' binutils-wrapper> unpacking sources binutils-wrapper> patching sources ... binutils-wrapper> Using dynamic linker: '/nix/store/kr51dlsj9v5cr4n8700jliyz8v5b2q7q-bootstrap-stage0-glibc/lib/ld-linux-x86-64.so.2' bootstrap-stage2-gcc-wrapper> unpacking sources ... linux-headers> unpacking sources linux-headers> unpacking source archive /nix/store/8javli69jhj3bkql2c35gsj5vl91p382-linux-4.19.16.tar.xz

2019-05-03 Fix "Bad system call" running i686-linux binaries on x86_64-linuxEelco Dolstra2-0/+7
To determine which seccomp filters to install, we were incorrectly using settings.thisSystem, which doesn't denote the actual system when --system is used. Fixes #2791.

2019-02-05 Revert "Restore parent mount namespace before executing a child process"Eelco Dolstra2-34/+0
This reverts commit a0ef21262f4d5652bfb65cfacaec01d89c475a93. This doesn't work in 'nix run' and nix-shell because setns() fails in multithreaded programs, and Boehm GC mark threads are uncancellable. Fixes #2646.

2018-12-13 Support SRI hashesEelco Dolstra2-17/+24
SRI hashes (https://www.w3.org/TR/SRI/) combine the hash algorithm and a base-64 hash. This allows more concise and standard hash specifications. For example, instead of import <nix/fetchurl.nl> { url = https://nixos.org/releases/nix/nix-2.1.3/nix-2.1.3.tar.xz; sha256 = "5d22dad058d5c800d65a115f919da22938c50dd6ba98c5e3a183172d149840a4"; }; you can write import <nix/fetchurl.nl> { url = https://nixos.org/releases/nix/nix-2.1.3/nix-2.1.3.tar.xz; hash = "sha256-XSLa0FjVyADWWhFfkZ2iKTjFDda6mMXjoYMXLRSYQKQ="; }; In fixed-output derivations, the outputHashAlgo is no longer mandatory if outputHash specifies the hash (either as an SRI or in the old "<type>:<hash>" format). 'nix hash-{file,path}' now print hashes in SRI format by default. I also reverted them to use SHA-256 by default because that's what we're using most of the time in Nixpkgs. Suggested by @zimbatm.

This ensures that they can't write to /nix/store. Fixes #2535.
2018-10-31 config: use all of XDG_CONFIG_DIRSLinus Heckemann2-0/+12
Previously, config would only be read from XDG_CONFIG_HOME. This change allows reading config from additional directories, which enables e.g. per-project binary caches or chroot stores with the help of direnv.
2018-10-16 RemoteStore: Close connection if an exception occursEelco Dolstra1-1/+5
Fixes #2075.
2018-09-26 sinkToSource(): Start the coroutine lazilyEelco Dolstra1-11/+15
In particular this causes copyStorePath() from HttpBinaryCacheStore to only start a download if needed. E.g. if the destination LocalStore goes to sleep waiting for the path lock and another process creates the path, then LocalStore::addToStore() will never read from the source so we don't have to do the download.

2018-09-04 Get effective user in Nix commandsMatthew Bauer1-1/+1
‘geteuid’ gives us the user that the command is being run as, including in setuid modes. By using geteuid to determind id, we can avoid the ‘sudo -i’ hack when upgrading Nix. So now, upgrading Nix on macOS is as simple as: $ sudo nix-channel --update $ sudo nix-env -u $ sudo launchctl stop org.nixos.nix-daemon $ sudo launchctl start org.nixos.nix-daemon or $ sudo systemctl restart nix-daemon

2018-08-06 Fix Brotli decompression in 'nix log'Eelco Dolstra2-325/+244
This didn't work anymore since decompression was only done in the non-coroutine case. Decompressors are now sinks, just like compressors. Also fixed a bug in bzip2 API handling (we have to handle BZ_RUN_OK rather than BZ_OK), which we didn't notice because there was a missing 'throw': if (ret != BZ_OK) CompressionError("error while compressing bzip2 file");

2018-07-31 Add a check for broken Boost versionsEelco Dolstra1-0/+4
In some Boost versions, coroutines don't propagate exceptions properly, causing Nix to fail with the exception 'coroutine has finished'.

2018-05-30 Make <nix/fetchurl.nix> run in constant memoryEelco Dolstra2-0/+19
E.g. nix-build --store ~/my-nix/ -E 'import <nix/fetchurl.nix> { url = https://cache.nixos.org/nar/0nwi996rgq4b914qyx0mv2wq4k80hjac7xilikavagw7kxmn2iiv.nar.xz; sha256 = "0nwi996rgq4b914qyx0mv2wq4k80hjac7xilikavagw7kxmn2iiv"; }' now runs in 17 MiB (was 70 MiB), while nix-build --store ~/my-nix/ -E 'import <nix/fetchurl.nix> { url = https://cache.nixos.org/nar/0nwi996rgq4b914qyx0mv2wq4k80hjac7xilikavagw7kxmn2iiv.nar.xz; sha256 = "0d2fxljdih3nc5dqx41hjzic3141ajil94m8kdbpryq569dpsbvb"; unpack = true; }' runs in 17 MiB (was 346 MiB).
2018-05-30 Make LocalBinaryCacheStore::narFromPath() run in constant memoryEelco Dolstra2-1/+10
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.
2018-05-30 Simplify the callback mechanismEelco Dolstra1-33/+20
2018-05-30 Modularize config settingsEelco Dolstra4-49/+150
Allow global config settings to be defined in multiple Config classes. For example, this means that libutil can have settings and evaluator settings can be moved out of libstore. The Config classes are registered in a new GlobalConfig class to which config files etc. are applied. Relevant to https://github.com/NixOS/nix/issues/2009 in that it removes the need for ad hoc handling of useCaseHack, which was the underlying cause of that issue.

2018-05-02 Fix bzip2 compression of files > 4 GiBEelco Dolstra1-3/+14
Bzip2's 'avail_in' parameter is declared as an unsigned int, so assigning a size_t length to it led to silent truncation. Fixes #2111.

2018-03-21 Make 'nix copy --from ssh://...' run in constant memoryEelco Dolstra2-0/+20
For instance, this reduced the memory consumption of $ nix copy --from ssh://localhost --to ~/my-nix /nix/store/1n7x0yv8vq6zi90hfmian84vdhd04bgp-blender-2.79a from 632 MiB to 16 MiB.

2018-03-16 Reduce substitution memory consumptionEelco Dolstra3-1/+87
copyStorePath() now pipes the output of srcStore->narFromPath() directly into dstStore->addToStore(). The sink used by the former is converted into a source usable by the latter using boost::coroutine2. This is based on [1]. This reduces the maximum resident size of $ nix build --store ~/my-nix/ /nix/store/b0zlxla7dmy1iwc3g459rjznx59797xy-binutils-2.28.1 --substituters file:///tmp/binary-cache-xz/ --no-require-sigs from 418592 KiB to 53416 KiB. (The previous commit also reduced the runtime from ~4.2s to ~3.4s, not sure why.) A further improvement will be to download files into a Sink. [1] https://github.com/NixOS/nix/compare/master...Mathnerd314:dump-fix-coroutine#diff-dcbcac55a634031f9cc73707da6e4b18 Issue #1969.
