2012-11-26 Make "nix-build -A <derivation>.<output>" do the right thingEelco Dolstra1-5/+15
For example, given a derivation with outputs "out", "man" and "bin": $ nix-build -A pkg produces ./result pointing to the "out" output; $ nix-build -A pkg.man produces ./result-man pointing to the "man" output; $ nix-build -A pkg.all produces ./result, ./result-man and ./result-bin; $ nix-build -A pkg.all -A pkg2 produces ./result, ./result-man, ./result-bin and ./result-2.
2012-11-20 nix-store -r: Add ‘--ignore-unknown’ flagEelco Dolstra1-9/+25
This flag causes paths that do not have a known substitute to be quietly ignored. This is mostly useful for Charon, allowing it to speed up deployment by letting a machine use substitutes for all substitutable paths, instead of uploading them. The latter is frequently faster, e.g. if the target machine has a fast Internet connection while the source machine is on a slow ADSL line.
2012-11-19 nix-store -r: Don't quietly ignore missing pathsEelco Dolstra1-0/+1
2012-10-03 When ‘--help’ is given, just run ‘man’ to show the manual pageEelco Dolstra1-2/+1
I.e. do what git does. I'm too lazy to keep the builtin help text up to date :-) Also add ‘--help’ to various commands that lacked it (e.g. nix-collect-garbage).
2012-10-02 Add a --repair flag to ‘nix-store -r’ to repair derivation outputsEelco Dolstra1-1/+3
With this flag, if any valid derivation output is missing or corrupt, it will be recreated by using a substitute if available, or by rebuilding the derivation. The latter may use hash rewriting if chroots are not available.
2012-10-02 nix-store -r: Get rid of an unnecessary call to buildPaths/ensurePathsEelco Dolstra1-4/+4
2012-10-02 nix-store --verify: Add an option ‘--repair’ to repair all ↵Eelco Dolstra1-2/+6
missing/corrupt paths Also, return a non-zero exit code if errors remain after verifying/repairing.
2012-10-02 Add operation ‘nix-store --repair-path’Eelco Dolstra1-0/+17
This operation allows fixing corrupted or accidentally deleted store paths by redownloading them using substituters, if available. Since the corrupted path cannot be replaced atomically, there is a very small time window (one system call) during which neither the old (corrupted) nor the new (repaired) contents are available. So repairing should be used with some care on critical packages like Glibc.
2012-08-27 Merge branch 'master' into no-manifestsEelco Dolstra1-9/+12
2012-08-24 Include the output name in the GC root linkEelco Dolstra1-3/+7
Output names are now appended to resulting GC symlinks, e.g. by nix-build. For backwards compatibility, if the output is named "out", nothing is appended. E.g. doing "nix-build -A foo" on a derivation that produces outputs "out", "bin" and "dev" will produce symlinks "./result", "./result-bin" and "./result-dev", respectively.
2012-08-01 Drop the block count in the garbage collectorEelco Dolstra1-5/+4
2012-08-01 nix-store --gc: Make ‘--max-freed 0’ do the right thingEelco Dolstra1-1/+1
That is, delete almost nothing (it will still remove unused links from /nix/store/.links).
2012-07-30 Refactor settings processingEelco Dolstra1-35/+35
Put all Nix configuration flags in a Settings object.
2012-07-26 Merge branch 'master' into no-manifestsEelco Dolstra1-8/+2
2012-07-23 optimiseStore(): Use a content-addressed file store in /nix/store/.linksEelco Dolstra1-8/+2
optimiseStore() now creates persistent, content-addressed hard links in /nix/store/.links. For instance, if it encounters a file P with hash H, it will create a hard link P' = /nix/store/.link/<H> to P if P' doesn't already exist; if P' exist, then P is replaced by a hard link to P'. This is better than the previous in-memory map, because it had the tendency to unnecessarily replace hard links with a hard link to whatever happened to be the first file with a given hash it encountered. It also allows on-the-fly, incremental optimisation.
2012-07-11 Rename queryValidPaths() to queryAllValidPaths()Eelco Dolstra1-1/+1
2012-06-27 nix-store -r: do substitutions in parallelEelco Dolstra1-7/+5
I.e. when multiple non-derivation arguments are passed to ‘nix-store -r’ to be substituted, do them in parallel.
2012-05-30 "nix-store -l": support compressed logsEelco Dolstra1-8/+33
2012-05-29 Reserve some disk space for the garbage collectorEelco Dolstra1-1/+1
We can't open a SQLite database if the disk is full. Since this prevents the garbage collector from running when it's most needed, we reserve some dummy space that we can free just before doing a garbage collection. This actually revives some old code from the Berkeley DB days. Fixes #27.
2012-03-26 Remove the --max-links GC optionEelco Dolstra1-1/+0
We don't need this anymore now that current filesystems support more than 32,000 files in a directory.
2012-02-09 Use data() instead of c_str() where appropriateEelco Dolstra1-1/+1
2012-01-17 * Added a command ‘nix-store --print-env $drvpath’ that prints out theEelco Dolstra1-0/+35
environment of the given derivation in a format that can be sourced by the shell, e.g. $ eval "$(nix-store --print-env $(nix-instantiate /etc/nixos/nixpkgs -A pkg))" $ NIX_BUILD_TOP=/tmp $ source $stdenv/setup This is especially useful to reproduce the environment used to build a package outside of its builder for development purposes. TODO: add a nix-build option to do the above and fetch the dependencies of the derivation as well.
2011-12-30 * Support multiple outputs in nix-store (specifically the ‘--query’Eelco Dolstra1-43/+63
and ‘--realise’ actions).
2011-12-16 * importPath() -> importPaths(). Because of buffering of the inputEelco Dolstra1-6/+4
stream it's now necessary for the daemon to process the entire sequence of exported paths, rather than letting the client do it.
2011-12-02 * Move parseHash16or32 into libutil, and use in nix-hash.Eelco Dolstra1-8/+0
2011-11-23 * Add an API function exportPaths() that provides the functionality ofEelco Dolstra1-5/+1
‘nix-store --export’. * Add a Perl module that provides the functionality of ‘nix-copy-closure --to’. This is used by build-remote.pl so it no longer needs to start a separate nix-copy-closure process. Also, it uses the Perl API to do the export, so it doesn't need to start a separate nix-store process either. As a result, nix-copy-closure and build-remote.pl should no longer fail on very large closures due to an "Argument list too long" error. (Note that having very many dependencies in a single derivation can still fail because the environment can become too large. Can't be helped though.)
2011-09-06 * Added a command ‘nix-store --verify-paths PATHS’ to check whetherEelco Dolstra1-1/+25
the contents of any of the given store paths have been modified. E.g. $ nix-store --verify-path $(nix-store -qR /var/run/current-system) path `/nix/store/m2smyiwbxidlprfxfz4rjlvz2c3mg58y-etc' was modified! expected hash `fc87e271c5fdf179b47939b08ad13440493805584b35e3014109d04d8436e7b8', got `20f1a47281b3c0cbe299ce47ad5ca7340b20ab34246426915fce0ee9116483aa' All paths are checked; the exit code is 1 if any path has been modified, 0 otherwise.
2011-08-31 * Eliminate all uses of the global variable ‘store’ from libstore.Eelco Dolstra1-13/+13
This should also fix: nix-instantiate: ./../boost/shared_ptr.hpp:254: T* boost::shared_ptr<T>::operator->() const [with T = nix::StoreAPI]: Assertion `px != 0' failed. which was caused by hashDerivationModulo() calling the ‘store’ object (during store upgrades) before openStore() assigned it.
2010-11-17 * Add an operation `nix-store -q --size'.Eelco Dolstra1-4/+9
2010-11-16 * Store the size of a store path in the database (to be precise, theEelco Dolstra1-5/+7
size of the NAR serialisation of the path, i.e., `nix-store --dump PATH'). This is useful for Hydra.
2010-11-16 * Sync with the trunk.Eelco Dolstra1-3/+3
2010-10-04 * Make sure that config.h is included before the system headers,Eelco Dolstra1-3/+3
because it defines _FILE_OFFSET_BITS. Without this, on OpenSolaris the system headers define it to be 32, and then the 32-bit stat() ends up being called with a 64-bit "struct stat", or vice versa. This also ensures that we get 64-bit file sizes everywhere. * Remove the redundant call to stat() in parseExprFromFile(). The file cannot be a symlink because that's the exit condition of the loop before.
2010-06-21 * Sync with the trunk.Eelco Dolstra1-2/+12
2010-05-31 Add XML output to `nix-store'.Ludovic Courtès1-2/+12
* src/nix-store/Makefile.am (nix_store_SOURCES): Add `xmlgraph.cc' and `xmlgraph.hh'. * src/nix-store/help.txt (Operations): Document `--xml'. * src/nix-store/nix-store.cc (opQuery): Handle `--xml'. * src/nix-store/xmlgraph.cc, src/nix-store/xmlgraph.hh: New files.
2010-05-04 * Allow unprivileged users to do `nix-store --clear-failed-paths' andEelco Dolstra1-2/+2
`nix-store --query-failed-paths'.
2010-04-26 * Added a command `nix-store --clear-failed-paths <PATHS>' to clearEelco Dolstra1-1/+11
the "failed" status of the given store paths. The special value `*' clears all failed paths.
2010-04-26 * Add an command `nix-store --query-failed-paths' to list the cachedEelco Dolstra1-3/+14
failed paths (when using the `build-cache-failure' option).
2010-02-24 * `helpText' is now zero-terminated.Eelco Dolstra1-1/+1
2010-01-25 * Made `nix-store -qR --include-outputs' much faster if there areEelco Dolstra1-38/+2
multiple paths specified on the command line (from O(n * m) to O(n + m), where n is the number of arguments and m is the size of the closure).
2009-11-24 * Templatise getIntArg / string2Int.Eelco Dolstra1-3/+3
2009-11-23 * A command `nix-store --query --roots <paths>' to find the garbageEelco Dolstra1-24/+23
collector roots that point (directly or indirectly) to the given paths.
2009-11-23 * `nix-store --gc --print-roots': also print the path of the actualEelco Dolstra1-7/+16
root symlink, not just its target. E.g.: /nix/var/nix/profiles/system-99-link -> /nix/store/76kwf88657nq7wgk1hx3l1z5q91zb9wd-system
2009-11-20 * Remove the --use-atime / --max-atime garbage collector flags. ManyEelco Dolstra1-5/+0
(Linux) machines no longer maintain the atime because it's too expensive, and on the machines where --use-atime is useful (like the buildfarm), reading the atimes on the entire Nix store takes way too much time to make it practical.
2009-03-26 * Don't use ULLONG_MAX in maxFreed - use 0 to mean "no limit".Eelco Dolstra1-1/+4
18446744073709551615ULL breaks on GCC 3.3.6 (`integer constant is too large for "long" type').
2009-03-22 * Better error message when nix-store --import is applied to garbageEelco Dolstra1-1/+1
(previously it would likely say "implementation cannot deal with > 32-bit integers").
2009-03-22 * NAR archives: handle files larger than 2^32 bytes. Previously itEelco Dolstra1-3/+6
would just silently store only (fileSize % 2^32) bytes. * Use posix_fallocate if available when unpacking archives. * Provide a better error message when trying to unpack something that isn't a NAR archive.
2008-12-12 * Simplify deleting .lock files in /nix/store: just don't delete themEelco Dolstra1-1/+1
if they belong a path that's currently being built. This gets rid of some Cygwin-specific code.
2008-12-03 * Pass HashType values instead of strings.Eelco Dolstra1-3/+3
2008-12-03 * Unify the treatment of sources copied to the store, and recursiveEelco Dolstra1-1/+4
SHA-256 outputs of fixed-output derivations. I.e. they now produce the same store path: $ nix-store --add x /nix/store/j2fq9qxvvxgqymvpszhs773ncci45xsj-x $ nix-store --add-fixed --recursive sha256 x /nix/store/j2fq9qxvvxgqymvpszhs773ncci45xsj-x the latter being the same as the path that a derivation derivation { name = "x"; outputHashAlgo = "sha256"; outputHashMode = "recursive"; outputHash = "..."; ... }; produces. This does change the output path for such fixed-output derivations. Fortunately they are quite rare. The most common use is fetchsvn calls with SHA-256 hashes. (There are a handful of those is Nixpkgs, mostly unstable development packages.) * Documented the computation of store paths (in store-api.cc).
2008-11-19 * nix-store --dump-db: be more streamy.Eelco Dolstra1-3/+3
