2012-07-02 nix-push: Always generate base-32 hashesEelco Dolstra1-2/+2
2012-07-02 Binary caches: use a better keyEelco Dolstra1-3/+3
Use the hash part of the store path as a key rather than a hash of the store path. This is enough to get the desired privacy property.
2012-07-01 Allow both bzip2 and xz compressionEelco Dolstra1-20/+41
2012-06-29 nix-push: Don't pollute the current directory with result symlinkEelco Dolstra1-1/+1
2012-06-29 DohEelco Dolstra1-1/+1
2012-06-29 Use XZ compression in binary cachesEelco Dolstra1-13/+13
XZ compresses significantly better than bzip2. Here are the compression ratios and execution times (using 4 cores in parallel) on my /var/run/current-system (3.1 GiB): bzip2: total compressed size 849.56 MiB, 30.8% [2m08] xz -6: total compressed size 641.84 MiB, 23.4% [6m53] xz -7: total compressed size 621.82 MiB, 22.6% [7m19] xz -8: total compressed size 599.33 MiB, 21.8% [7m18] xz -9: total compressed size 588.18 MiB, 21.4% [7m40] Note that compression takes much longer. More importantly, however, decompression is much faster: bzip2: 1m47.274s xz -6: 0m55.446s xz -7: 0m54.119s xz -8: 0m52.388s xz -9: 0m51.842s The only downside to using -9 is that decompression takes a fair amount (~65 MB) of memory.
2012-06-28 nix-push: create a manifest-less binary cacheEelco Dolstra1-159/+93
Manifests are a huge pain, since users need to run nix-pull directly or indirectly to obtain them. They tend to be large and lag behind the available binaries; also, the downloaded manifests in /nix/var/nix/manifest need to be in sync with the Nixpkgs sources. So we want to get rid of them. The idea of manifest-free operation works as follows. Nix is configured with a set of URIs of binary caches, e.g. http://nixos.org/binary-cache Whenever Nix needs a store path X, it checks each binary cache for the existence of a file <CACHE-URI>/<SHA-256 hash of X>.narinfo, e.g. http://nixos.org/binary-cache/bi1gh9...ia17.narinfo The .narinfo file contains the necessary information about the store path that was formerly kept in the manifest, i.e., (relative) URI of the compressed NAR, references, size, hash, etc. For example: StorePath: /nix/store/xqp4l88cr9bxv01jinkz861mnc9p7qfi-neon-0.29.6 URL: 1bjxbg52l32wj8ww47sw9f4qz0r8n5vs71l93lcbgk2506v3cpfd.nar.bz2 CompressedHash: sha256:1bjxbg52l32wj8ww47sw9f4qz0r8n5vs71l93lcbgk2506v3cpfd CompressedSize: 202542 NarHash: sha256:1af26536781e6134ab84201b33408759fc59b36cc5530f57c0663f67b588e15f NarSize: 700440 References: 043zrsanirjh8nbc5vqpjn93hhrf107f-bash-4.2-p24 cj7a81wsm1ijwwpkks3725661h3263p5-glibc-2.13 ... Deriver: 4idz1bgi58h3pazxr3akrw4fsr6zrf3r-neon-0.29.6.drv System: x86_64-linux Nix then knows that it needs to download http://nixos.org/binary-cache/1bjxbg52l32wj8ww47sw9f4qz0r8n5vs71l93lcbgk2506v3cpfd.nar.bz2 to substitute the store path. Note that the store directory is omitted from the References and Deriver fields to save space, and that the URL can be relative to the binary cache prefix. This patch just makes nix-push create binary caches in this format. The next step is to make a substituter that supports them.
2012-04-14 Remove unnecessary "system" argumentEelco Dolstra1-1/+1
2012-01-03 * Use Nix::Config.Eelco Dolstra1-10/+8
2012-01-03 * Refactoring: Get rid of a few subdirectories in corepkgs/, and someEelco Dolstra1-4/+1
other simplifications. * Use <nix/...> to locate the corepkgs. This allows them to be overriden through $NIX_PATH. * Use bash's pipefail option in the NAR builder so that we don't need to create a temporary file.
2011-11-29 * For consistency with "nix-store -q --hash", produce hashes inEelco Dolstra1-2/+2
base-32. (This affects Hydra manifests.)
2011-10-10 * Set the executable bit on scripts.Eelco Dolstra1-0/+0
2011-10-10 * Install NixManifest.pm, NixConfig.pm and GeneratePatches.pm underEelco Dolstra1-4/+5
the Nix:: namespace.
2011-04-11 * configure: detect whether DBD::SQLite is present. If necessary theEelco Dolstra1-1/+1
location to DBI and DBD::SQLite can be passed with --with-dbi and --with-dbd-sqlite.
2011-04-11 * Subtle bug: if you import File::stat in one module, it affects otherEelco Dolstra1-1/+2
modules as well. So use symbolic field names everywhere (which is nicer anyway).
2011-02-17 (no commit message)Eelco Dolstra1-1/+1
2011-02-17 * nix-push: handle the case where the hash is not set in the DB.Eelco Dolstra1-0/+10
2010-12-05 * Use CamelCase for the Perl modules.Eelco Dolstra1-1/+1
2010-11-17 * Store the NAR size in the manifest.Eelco Dolstra1-0/+5
2010-11-17 * nix-push: no need to compute the NAR hash, since the Nix databaseEelco Dolstra1-7/+5
already has it (`nix-store -q --hash').
2009-03-18 * Unify exportReferencesGraph and exportBuildReferencesGraph, and makeEelco Dolstra1-5/+1
sure that it works as expected when you pass it a derivation. That is, we have to make sure that all build-time dependencies are built, and that they are all in the input closure (otherwise remote builds might fail, for example). This is ensured at instantiation time by adding all derivations and their sources to inputDrvs and inputSrcs.
2008-12-04 * Dirty hack to make nix-push work properly on derivations: theEelco Dolstra1-2/+1
derivation should be a source rather than a derivation dependency of the call to the NAR derivation. Otherwise the derivation (and all its dependencies) will be built as a side-effect, which may not even succeed.
2008-11-20 * Urgh.Eelco Dolstra1-2/+1
2008-11-19 * Primop builtins.storePath for declaring a store path as aEelco Dolstra1-1/+1
dependency. `storePath /nix/store/bla' gives exactly the same result as `toPath /nix/store/bla', except that the former includes /nix/store/bla in the dependency context of the string. Useful in some generated Nix expressions like nix-push, which now finally does the right thing wrt distributed builds. (Previously the path to be packed wasn't an explicit dependency, so it wouldn't be copied to the remote machine.)
2008-03-20 * Cleanup.Eelco Dolstra1-5/+9
2007-12-30 * Don't use "store expression", it's obsolete.Eelco Dolstra1-2/+2
2007-11-16 * Flag `--no-build-hook' to disable distributed builds.Eelco Dolstra1-1/+1
* queryDeriver in daemon mode: don't barf if the other side returns an empty string (which means there is no deriver).
2007-09-04 * nix-push / generate-patches: bzip the manifest.Eelco Dolstra1-0/+4
2007-08-15 * Show errors in nix-prefetch-url.Eelco Dolstra1-1/+1
2006-10-04 * tmpnam() -> File::Temp::tempdir().Eelco Dolstra1-10/+7
2006-09-25 * Clean up calls to system().Eelco Dolstra1-1/+1
2006-09-25 * Use builtins.toPath.Eelco Dolstra1-2/+2
2006-09-20 * Use paths, not strings, when calling the function that generatesEelco Dolstra1-10/+17
NARs. Fixes the impurity of nix-push (NIX-21). * Better help.
2006-08-09 * file:/ -> file://Eelco Dolstra1-1/+1
2006-08-08 rework the --target flag. If this flag is used, a URI should be given. DefaultArmijn Hemel1-4/+4
values are not changed.
2006-08-07 * In nar.nix, path -> storePath, otherwise we get a collision betweenEelco Dolstra1-1/+1
environment variable names on Cygwin (where they are case insensitive).
2006-08-03 urgh...for some weird reason this one-liner was not in svn. PEBKAC!Armijn Hemel1-1/+1
2006-08-01 add a flag --target, so we can override the URL in the MANIFEST file. ThisArmijn Hemel1-0/+9
is only for local copies (so file:///)
2005-11-17 * FreeBSD compatibility fix.Eelco Dolstra1-1/+2
2005-10-29 * Turn off build hooks in nix-push because of an impurity (NIX-21).Eelco Dolstra1-1/+11
2005-09-21 * Remove other uses of IPC::Open2.Eelco Dolstra1-20/+8
2005-03-15 * Use SHA-256 for nix-push.Eelco Dolstra1-17/+29
2005-03-14 * Set NAR name to content hash; previous nix-push names were notEelco Dolstra1-11/+10
unique. * Drop `hashAlgo' attribute in manifests; prefix hashes with the hash algorithm instead.
2005-02-24 * (Unnecessary) refactoring.Eelco Dolstra1-29/+36
2005-02-17 * Fix nix-channel.Eelco Dolstra1-6/+6
* Add `--help' flag; fixes NIX-5. * Add `--remove' flag; fixes NIX-6. * Add `--list' flag.
2005-02-09 * Propagate the deriver of a path through the substitute mechanism.Eelco Dolstra1-19/+10
* Removed some dead code (successor stuff) from nix-push. * Updated terminology in the tests (store expr -> drv path). * Check that the deriver is set properly in the tests.
2005-01-25 * Really fix the substitute mechanism, i.e., ensure the closureEelco Dolstra1-30/+87
invariant by registering references through the manifest. * Added a test for nix-pull.
2005-01-19 * Set the Perl search path properly (reported by Roy van den Broek).Eelco Dolstra1-1/+1
2004-12-28 * Added a function to write manifests.Eelco Dolstra1-26/+29
2004-12-13 * Include the size of the bzipped archive (necessary for computing theEelco Dolstra1-5/+15
cheapest download path), as well as the hash of the contents of the path (necessary for checking patch applicability).
