2018-02-12 Fix hang in build-remoteEelco Dolstra1-0/+3
2018-01-31 Rename 1.12 -> 2.0Eelco Dolstra1-1/+1
Following discussion with Shea and Graham. It's a big enough change from the last release. Also, from a semver perspective, 2.0 makes more sense because we did remove some interfaces (like nix-pull/nix-push).
2017-11-20 signed-binary-caches -> require-sigsEelco Dolstra1-1/+1
Unlike signed-binary-caches (which could only be '*' or ''), require-sigs is a proper Boolean option. The default is true.
2017-09-14 Show the pid of temporary rootsEelco Dolstra1-1/+1
2017-09-14 nix-store -q --roots / --gc --print-roots: Print temporary / in-memory rootsEelco Dolstra1-2/+4
For example, $ nix-store -q --roots /nix/store/7phd2sav7068nivgvmj2vpm3v47fd27l-patchelf-0.8pre845_0315148 {temp:1} denotes that the path is only being kept alive by a temporary root (i.e. /nix/var/nix/temproots/). Similarly, $ nix-store --gc --print-roots ... {memory:9} -> /nix/store/094gpjn9f15ip17wzxhma4r51nvsj17p-curl-7.53.1 shows that curl is being used by some process.
2017-09-05 Add automatic garbage collectionEelco Dolstra1-0/+21
Nix can now automatically run the garbage collector during builds or while adding paths to the store. The option "min-free = <bytes>" specifies that Nix should run the garbage collector whenever free space in the Nix store drops below <bytes>. It will then delete garbage until "max-free" bytes are available. Garbage collection during builds is asynchronous; running builds are not paused and new builds are not blocked. However, there also is a synchronous GC run prior to the first build/substitution. Currently, no old GC roots are deleted (as in "nix-collect-garbage -d").
2017-09-05 GC: Don't delete own temproots fileEelco Dolstra1-1/+2
Since file locks are per-process rather than per-file-descriptor, the garbage collector would always acquire a lock on its own temproots file and conclude that it's stale.
2017-08-16 nix optimise-store: Show how much space has been freedEelco Dolstra1-1/+1
2017-07-03 Replace a few bool flags with enumsEelco Dolstra1-7/+8
Functions like copyClosure() had 3 bool arguments, which creates a severe risk of mixing up arguments. Also, implement copyClosure() using copyPaths().
2017-04-13 Merge branch 'rework-options' of https://github.com/copumpkin/nixEelco Dolstra1-1/+1
2017-04-13 Add a Config class to simplify adding configuration settingsEelco Dolstra1-1/+5
The typical use is to inherit Config and add Setting<T> members: class MyClass : private Config { Setting<int> foo{this, 123, "foo", "the number of foos to use"}; Setting<std::string> bar{this, "blabla", "bar", "the name of the bar"}; MyClass() : Config(readConfigFile("/etc/my-app.conf")) { std::cout << foo << "\n"; // will print 123 unless overriden } }; Currently, this is used by Store and its subclasses for store parameters. You now get a warning if you specify a non-existant store parameter in a store URI.
2017-04-10 Minor cleanupEelco Dolstra1-8/+3
Also, possible fix for #1310 on 32-bit systems.
2017-03-16 copyPaths(): Use queryValidPaths() to reduce SSH latencyEelco Dolstra1-1/+1
2017-03-15 Store: Add a method for getting build logsEelco Dolstra1-3/+0
This allows various Store implementations to provide different ways to get build logs. For example, BinaryCacheStore can get the build logs from the binary cache. Also, remove the log-servers option since we can use substituters for this.
2016-11-26 Revert "Get rid of unicode quotes (#1140)"Eelco Dolstra1-1/+1
This reverts commit f78126bfd6b6c8477fcdbc09b2f98772dbe9a1e7. There really is no need for such a massive change...
2016-11-25 Get rid of unicode quotes (#1140)Guillaume Maudoux1-1/+1
2016-10-21 Remove addPathToAccessorEelco Dolstra1-4/+5
2016-10-21 BinaryCacheStore: Optionally write a NAR listingEelco Dolstra1-1/+1
The store parameter "write-nar-listing=1" will cause BinaryCacheStore to write a file ‘<store-hash>.ls.xz’ for each ‘<store-hash>.narinfo’ added to the binary cache. This file contains an XZ-compressed JSON file describing the contents of the NAR, excluding the contents of regular files. E.g. { "version": 1, "root": { "type": "directory", "entries": { "lib": { "type": "directory", "entries": { "Mcrt1.o": { "type": "regular", "size": 1288 }, "Scrt1.o": { "type": "regular", "size": 3920 }, } } } ... } } (The actual file has no indentation.) This is intended to speed up the NixOS channels programs index generator [1], since fetching gazillions of large NARs from cache.nixos.org is currently a bottleneck for updating the regular (non-small) channel. [1] https://github.com/NixOS/nixos-channel-scripts/blob/master/generate-programs-index.cc
2016-09-16 Make computeFSClosure() single-threaded againEelco Dolstra1-1/+3
The fact that queryPathInfo() is synchronous meant that we needed a thread for every concurrent binary cache lookup, even though they end up being handled by the same download thread. Requiring hundreds of threads is not a good idea. So now there is an asynchronous version of queryPathInfo() that takes a callback function to process the result. Similarly, enqueueDownload() now takes a callback rather than returning a future. Thus, a command like nix path-info --store https://cache.nixos.org/ -r /nix/store/slljrzwmpygy1daay14kjszsr9xix063-nixos-16.09beta231.dccf8c5 that returns 4941 paths now takes 1.87s using only 2 threads (the main thread and the downloader thread). (This is with a prewarmed CloudFront.)
2016-08-10 Mark content-addressed paths in the Nix database and in .narinfoEelco Dolstra1-2/+2
This allows such paths to be imported without signatures.
2016-06-02 Make derivationFromPath work on diverted storesEelco Dolstra1-0/+2
2016-06-02 nix run: Mount the Nix store in a private namespaceEelco Dolstra1-0/+4
This is a convenience command to allow users who are not privileged to create /nix/store to use Nix with regular binary caches. For example, $ NIX_REMOTE="local?state=$HOME/nix/var&real=/$HOME/nix/store" nix run firefox bashInteractive will download Firefox and bash from cache.nixos.org, then start a shell in which $HOME/nix/store is mounted on /nix/store.
2016-06-02 LocalStore: Allow the physical and logical store directories to differEelco Dolstra1-0/+2
This is primarily to subsume the functionality of the copy-from-other-stores substituter. For example, in the NixOS installer, we can now do (assuming we're in the target chroot, and the Nix store of the installation CD is bind-mounted on /tmp/nix): $ nix-build ... --option substituters 'local?state=/tmp/nix/var&real=/tmp/nix/store' However, unlike copy-from-other-stores, this also allows write access to such a store. One application might be fetching substitutes for /nix/store in a situation where the user doesn't have sufficient privileges to create /nix, e.g.: $ NIX_REMOTE="local?state=/home/alice/nix/var&real=/home/alice/nix/store" nix-build ...
2016-06-02 Allow setting the state directory as a store parameterEelco Dolstra1-2/+10
E.g. "local?store=/tmp/store&state=/tmp/var".
2016-06-01 Make the store directory a member variable of StoreEelco Dolstra1-1/+1
2016-05-31 nix-copy-closure / build-remote.pl: Disable signature checkingEelco Dolstra1-1/+1
This restores the Nix 1.11 behaviour.
2016-05-30 Check signatures before downloading the substituteEelco Dolstra1-0/+1
2016-05-30 Re-implement binary cache signature checkingEelco Dolstra1-0/+4
This is now done in LocalStore::addToStore(), rather than in the binary cache substituter (which no longer exists).
2016-05-04 Add a Store::addToStore() variant that accepts a NAREelco Dolstra1-7/+3
As a side effect, this ensures that signatures are propagated when copying paths between stores. Also refactored import/export to make use of this.
2016-05-04 Remove OpenSSL-based signingEelco Dolstra1-4/+3
2016-04-29 Allow parameters in store URIsEelco Dolstra1-0/+2
This is to allow store-specific configuration, e.g. s3://my-cache?compression=bzip2&secret-key=/path/to/key.
2016-04-29 Eliminate the substituter mechanismEelco Dolstra1-27/+0
Substitution is now simply a Store -> Store copy operation, most typically from BinaryCacheStore to LocalStore.
2016-04-19 Move path info caching from BinaryCacheStore to StoreEelco Dolstra1-7/+3
Caching path info is generally useful. For instance, it speeds up "nix path-info -rS /run/current-system" (i.e. showing the closure sizes of all paths in the closure of the current system) from 5.6s to 0.15s. This also eliminates some APIs like Store::queryDeriver() and Store::queryReferences().
2016-04-08 Remove failed build cachingEelco Dolstra1-17/+2
This feature was implemented for Hydra, but Hydra no longer uses it.
2016-04-08 Make LocalStore thread-safeEelco Dolstra1-66/+52
Necessary for multi-threaded commands like "nix verify-paths".
2016-04-07 Sign locally-built pathsEelco Dolstra1-0/+6
Locally-built paths are now signed automatically using the secret keys specified by the ‘secret-key-files’ option.
2016-04-05 Add "nix copy-sigs" commandEelco Dolstra1-0/+2
This imports signatures from one store into another. E.g. $ nix copy-sigs -r /run/current-system -s https://cache.nixos.org/ imported 595 signatures
2016-03-30 LocalStore: Keep track of ultimately trusted pathsEelco Dolstra1-2/+2
These are content-addressed paths or outputs of locally performed builds. They are trusted even if they don't have signatures, so "nix verify-paths" won't complain about them.
2016-03-30 Improve the SQLite wrapper APIEelco Dolstra1-3/+4
In particular, this eliminates a bunch of boilerplate code.
2016-03-30 Factour out SQLite handlingEelco Dolstra1-33/+2
2016-02-26 importPaths(): Optionally add NARs to binary cache accessorEelco Dolstra1-1/+2
This enables an optimisation in hydra-queue-runner, preventing a download of a NAR it just uploaded to the cache when reading files like hydra-build-products.
2016-02-25 Add NAR / Store accessor abstractionEelco Dolstra1-4/+1
This is primary to allow hydra-queue-runner to extract files like "nix-support/hydra-build-products" from NARs in binary caches.
2016-02-24 Eliminate reserveSpace flagEelco Dolstra1-1/+3
2016-02-15 Expose the export magic value and move LocalStore::queryReferences to StoreEelco Dolstra1-2/+0
2016-02-04 StoreAPI -> StoreEelco Dolstra1-1/+1
Calling a class an API is a bit redundant...
2016-02-04 Eliminate the "store" global variableEelco Dolstra1-0/+4
Also, move a few free-standing functions into StoreAPI and Derivation. Also, introduce a non-nullable smart pointer, ref<T>, which is just a wrapper around std::shared_ptr ensuring that the pointer is never null. (For reference-counted values, this is better than passing a "T&", because the latter doesn't maintain the refcount. Usually, the caller will have a shared_ptr keeping the value alive, but that's not always the case, e.g., when passing a reference to a std::thread via std::bind.)
2016-01-31 Use the daemon when we don't have write access to the Nix databaseEelco Dolstra1-0/+6
2015-09-18 Shut up clang warningsEelco Dolstra1-29/+29
2015-07-17 Allow remote builds without sending the derivation closureEelco Dolstra1-0/+3
Previously, to build a derivation remotely, we had to copy the entire closure of the .drv file to the remote machine, even though we only need the top-level derivation. This is very wasteful: the closure can contain thousands of store paths, and in some Hydra use cases, include source paths that are very large (e.g. Git/Mercurial checkouts). So now there is a new operation, StoreAPI::buildDerivation(), that performs a build from an in-memory representation of a derivation (BasicDerivation) rather than from a on-disk .drv file. The only files that need to be in the Nix store are the sources of the derivation (drv.inputSrcs), and the needed output paths of the dependencies (as described by drv.inputDrvs). "nix-store --serve" exposes this interface. Note that this is a privileged operation, because you can construct a derivation that builds any store path whatsoever. Fixing this will require changing the hashing scheme (i.e., the output paths should be computed from the other fields in BasicDerivation, allowing them to be verified without access to other derivations). However, this would be quite nice because it would allow .drv-free building (e.g. "nix-env -i" wouldn't have to write any .drv files to disk). Fixes #173.
