2021-03-10Use libarchive for all compressionYorick van Pelt
2020-12-02read(): Use char * instead of unsigned char *Eelco Dolstra
This gets rid of some pointless casts.
2020-12-02Sink: Use std::string_viewEelco Dolstra
2020-10-30Fix memory corruption caused by GC-invisible coroutine stacksRobert Hensing
Crucially this introduces BoehmGCStackAllocator, but it also adds a bunch of wiring to avoid making libutil depend on bdw-gc. Part of the solutions for #4178, #4200
2020-10-07Serialize exceptions from the sandbox process to the parentEelco Dolstra
Fixes #4118.
2020-09-22Merge branch 'add-ca-to-store' of https://github.com/hercules-ci/nixEelco Dolstra
2020-09-22Silence a compiler warning in serialise.hhregnat
Explicitely cast to `uint64_t` in `readNum` to avoid a "comparison between signed and unsigned" warning
2020-09-21Move FramedSink next to FramedSourceRobert Hensing
2020-09-17Move FramedSource and FramedSink, extract withFramedSinkRobert Hensing
2020-09-17Add Source.drainInto(Sink)Robert Hensing

2020-08-27RemoteStore::addToStore(): Fix race between stderrThread and NAR writerEelco Dolstra
As pointed out by @B4dM4n, the call to to.flush() on stderrThread is unsafe because the NAR writer thread is also writing to 'to'. Fixes #3943.
2020-08-14Merge remote-tracking branch 'upstream/master' into single-ca-drv-buildJohn Ericson
2020-08-13Use `TeeSink` and `TeeSouce` in a few more placesJohn Ericson
2020-08-07Squashed get CA derivations buildingJohn Ericson
2020-07-30unsigned long long -> uint64_tEelco Dolstra
2020-07-16Fix bug in TeeSourceJohn Ericson
We use this to simplify `LocalStore::addToStoreFromDump`. Also, hope I fixed build error with old clang (used in Darwin CI).
2020-07-15Revert "LocalStore::addToStoreFromDump copy in chunks"John Ericson
This reverts commit 592851fb67cd15807109d6f65fb81f6af89af966. We don't need this extra feature anymore
2020-07-15Get rid of `LocalStore::addToStoreCommon`John Ericson
I got it to just become `LocalStore::addToStoreFromDump`, cleanly taking a store and then doing nothing too fancy with it. `LocalStore::addToStore(...Path...)` is now just a simple wrapper with a bare-bones sinkToSource of the right dump command.
2020-07-14LocalStore::addToStoreFromDump copy in chunksJohn Ericson
Rather than copying byte-by-byte, we let the coroutine know how much data we would like it to send back to us.
2020-07-13Make 'nix copy' to s3:// binary caches run in constant memoryEelco Dolstra
2020-07-13NarAccessor: Run in constant memoryEelco Dolstra
2020-07-13Make 'nix copy' to file:// binary caches run in constant memoryEelco Dolstra
2020-04-29Remove the `drain` argument from `readFile`Guillaume Bouchard
Now it is always `drain` (see previous commit).
2019-11-26Drop remaining uses of external "tar"Eelco Dolstra
Also, fetchGit now runs in O(1) memory since we pipe the output of 'git archive' directly into unpackTarball() (rather than first reading it all into memory).
2019-11-10Fix extra ; warnings involving MakeErrorJohn Ericson
2019-10-21Allow content-addressable paths to have referencesEelco Dolstra
This adds a command 'nix make-content-addressable' that rewrites the specified store paths into content-addressable paths. The advantage of such paths is that 1) they can be imported without signatures; 2) they can enable deduplication in cases where derivation changes do not cause output changes (apart from store path hashes). For example, $ nix make-content-addressable -r nixpkgs.cowsay rewrote '/nix/store/g1g31ah55xdia1jdqabv1imf6mcw0nb1-glibc-2.25-49' to '/nix/store/48jfj7bg78a8n4f2nhg269rgw1936vj4-glibc-2.25-49' ... rewrote '/nix/store/qbi6rzpk0bxjw8lw6azn2mc7ynnn455q-cowsay-3.03+dfsg1-16' to '/nix/store/iq6g2x4q62xp7y7493bibx0qn5w7xz67-cowsay-3.03+dfsg1-16' We can then copy the resulting closure to another store without signatures: $ nix copy --trusted-public-keys '' ---to ~/my-nix /nix/store/iq6g2x4q62xp7y7493bibx0qn5w7xz67-cowsay-3.03+dfsg1-16 In order to support self-references in content-addressable paths, these paths are hashed "modulo" self-references, meaning that self-references are zeroed out during hashing. Somewhat annoyingly, this means that the NAR hash stored in the Nix database is no longer necessarily equal to the output of "nix hash-path"; for content-addressable paths, you need to pass the --modulo flag: $ nix path-info --json /nix/store/iq6g2x4q62xp7y7493bibx0qn5w7xz67-cowsay-3.03+dfsg1-16 | jq -r .[].narHash sha256:0ri611gdilz2c9rsibqhsipbfs9vwcqvs811a52i2bnkhv7w9mgw $ nix hash-path --type sha256 --base32 /nix/store/iq6g2x4q62xp7y7493bibx0qn5w7xz67-cowsay-3.03+dfsg1-16 1ggznh07khq0hz6id09pqws3a8q9pn03ya3c03nwck1kwq8rclzs $ nix hash-path --type sha256 --base32 /nix/store/iq6g2x4q62xp7y7493bibx0qn5w7xz67-cowsay-3.03+dfsg1-16 --modulo iq6g2x4q62xp7y7493bibx0qn5w7xz67 0ri611gdilz2c9rsibqhsipbfs9vwcqvs811a52i2bnkhv7w9mgw
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.
2018-09-26Make NAR header check more robustEelco Dolstra
Changes std::bad_alloc into bad archive: input doesn't look like a Nix archive
2018-08-21Improve 'coroutine has finished' error messageEelco Dolstra
2018-05-21serialise: fix buffer size used, hide method for internal use onlyWill Dietz
Fixes #2169.
2018-05-02Fix some random -Wconversion warningsEelco Dolstra
2018-03-16Reduce substitution memory consumptionEelco Dolstra
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.

2018-03-16decompress(): Use a Source and SinkEelco Dolstra
This allows decompression to happen in O(1) memory.
2017-10-23Pass all settings to build-remoteEelco Dolstra
This ensures that command line flags such as --builders get passed correctly.
2017-07-30Replace Unicode quotes in user-facing strings by ASCIIJörg Thalheim
Relevant RFC: NixOS/rfcs#4 $ ag -l | xargs sed -i -e "/\"/s/’/'/g;/\"/s/‘/'/g"
2017-03-01RemoteStore::addToStore(): Send NAR rather than string containing NAREelco Dolstra
This allows the NAR to be streamed in the future (though we're not doing that yet).
2017-03-01Handle importing NARs containing files greater than 4 GiBEelco Dolstra
Also templatize readInt() to work for various integer types.
2017-02-07Move SavingSourceAdapter to serialise.hhEelco Dolstra

This reverts commit f78126bfd6b6c8477fcdbc09b2f98772dbe9a1e7. There really is no need for such a massive change...

2016-02-24Remove bad daemon connections from the poolEelco Dolstra
This is necessary for long-running processes like hydra-queue-runner: if a nix-daemon worker is killed, we need to stop reusing that connection.
