2012-10-02Add a --repair flag to ‘nix-store -r’ to repair derivation outputsEelco Dolstra
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.
2012-10-02nix-store -r: Get rid of an unnecessary call to buildPaths/ensurePathsEelco Dolstra
2012-10-02nix-store --verify: Add an option ‘--repair’ to repair all ↵Eelco Dolstra
missing/corrupt paths Also, return a non-zero exit code if errors remain after verifying/repairing.
2012-10-02Add operation ‘nix-store --repair-path’Eelco Dolstra
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.
2012-08-27Merge branch 'master' into no-manifestsEelco Dolstra
2012-08-24Include the output name in the GC root linkEelco Dolstra
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.
2012-08-01Drop the block count in the garbage collectorEelco Dolstra
2012-08-01nix-store --gc: Make ‘--max-freed 0’ do the right thingEelco Dolstra
That is, delete almost nothing (it will still remove unused links from /nix/store/.links).
2012-07-30Refactor settings processingEelco Dolstra
Put all Nix configuration flags in a Settings object.

2012-07-23optimiseStore(): Use a content-addressed file store in /nix/store/.linksEelco Dolstra
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.
2012-07-18Use "#pragma once" to prevent repeated header file inclusionEelco Dolstra
2012-07-11Rename queryValidPaths() to queryAllValidPaths()Eelco Dolstra
2012-06-27nix-store -r: do substitutions in parallelEelco Dolstra
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 Dolstra
2012-05-29Reserve some disk space for the garbage collectorEelco Dolstra
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.
2012-04-04Include --keep-going in --helpEelco Dolstra
2012-03-26Remove the --max-links GC optionEelco Dolstra
We don't need this anymore now that current filesystems support more than 32,000 files in a directory.
2012-02-09Use data() instead of c_str() where appropriateEelco Dolstra
2012-01-17* Added a command ‘nix-store --print-env $drvpath’ that prints out theEelco Dolstra
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 Dolstra
and ‘--realise’ actions).
2011-12-16* importPath() -> importPaths(). Because of buffering of the inputEelco Dolstra
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 Dolstra
2011-11-23* Add an API function exportPaths() that provides the functionality ofEelco Dolstra
‘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 Dolstra
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 Dolstra
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 Dolstra
2010-11-16* Store the size of a store path in the database (to be precise, theEelco Dolstra
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 Dolstra
2010-10-04* Make sure that config.h is included before the system headers,Eelco Dolstra
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 Dolstra
2010-05-31Add XML output to `nix-store'.Ludovic Courtès
* 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.
2010-05-31Comment out dead code in `nix-store'.Ludovic Courtès
* src/nix-store/dotgraph.cc (pathLabel): Move within #if 0 section.
2010-05-04* Allow unprivileged users to do `nix-store --clear-failed-paths' andEelco Dolstra
`nix-store --query-failed-paths'.
2010-04-26(no commit message)Eelco Dolstra
2010-04-26* Added a command `nix-store --clear-failed-paths <PATHS>' to clearEelco Dolstra
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 Dolstra
failed paths (when using the `build-cache-failure' option).
2010-04-19* Drop the dependency on the ATerm library.Eelco Dolstra
2010-03-02* When using the included sqlite/aterm libraries, build withEelco Dolstra
--enable-shared. * In libutil/libstore/libexpr etc., link against sqlite and aterm. * Some more header file hygiene.
2010-02-24* `helpText' is now zero-terminated.Eelco Dolstra
2010-02-24* ADDITIONAL_NETWORK_LIBS -> LIBS.Eelco Dolstra
2010-02-24* Add ${sqlite_lib} everywhere. Just adding it in `libstore' doesn'tEelco Dolstra
work on x86_64 when sqlite is compiled statically.
2010-01-25* Made `nix-store -qR --include-outputs' much faster if there areEelco Dolstra
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 Dolstra
2009-11-23* A command `nix-store --query --roots <paths>' to find the garbageEelco Dolstra
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 Dolstra
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 Dolstra
(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.
2009-11-06* Remove support for old (before Nix 0.12pre12020) databases.Eelco Dolstra
2009-10-08Added optional parameter which adds -lnsl -lsocket to make the Nix package ↵Sander van der Burg
manager work on OpenSolaris
2009-03-26* Don't use ULLONG_MAX in maxFreed - use 0 to mean "no limit".Eelco Dolstra
18446744073709551615ULL breaks on GCC 3.3.6 (`integer constant is too large for "long" type').
