2012-02-04 * Inline some functions and get rid of the indirection throughEelco Dolstra7-116/+94
EvalState::eval(). This gives a 12% speedup on ‘nix-instantiate /etc/nixos/nixos/ -A system --readonly-mode’ (from 1.01s to 0.89s).
2012-02-04 * Print elapsed evaluation time.Eelco Dolstra1-1/+9
2012-01-26 * Fix importing a derivation. This gave a segfault.Eelco Dolstra1-8/+23
2012-01-19 * Allow comparisons between derivations by comparing the outPathEelco Dolstra1-2/+14
attributes.
2012-01-19 * Add some debug output to print the derivation name once it's known.Eelco Dolstra1-1/+4
This makes it easier to pinpoint the source of a crash.
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.
2012-01-07 * Don't create thunks for simple constants (integers, strings, paths)Eelco Dolstra5-133/+193
and allocate them only once. * Move Value and related functions into value.hh.
2012-01-04 * Remove dead code.Eelco Dolstra2-4/+0
2012-01-04 * Don't use dynamic_cast, it's very slow. "nix-instantiateEelco Dolstra3-24/+23
/etc/nixos/nixos -A system" spent about 10% of its time in dynamic_cast.
2012-01-03 * Drop the inefficient "Path" suffix in output attribute names.Eelco Dolstra1-3/+1
2012-01-03 * Move the implementation of the ‘derivation’ primop into a separateEelco Dolstra2-25/+3
file.
2012-01-03 * Sync with the trunk.Eelco Dolstra1-1/+1
2012-01-03 * Refactoring: Get rid of a few subdirectories in corepkgs/, and someEelco Dolstra1-1/+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.
2011-12-30 * Support multiple outputs in nix-store (specifically the ‘--query’Eelco Dolstra1-43/+63
and ‘--realise’ actions).
2011-12-30 * Oops.Eelco Dolstra1-1/+1
2011-12-30 * Move topoSortPaths() out of gc.cc.Eelco Dolstra2-36/+36
2011-12-30 * Reject a build if there is a cycle among the outputs. This isEelco Dolstra4-9/+24
necessary because existing code assumes that the references graph is acyclic.
2011-12-30 * Sync with the trunk.Eelco Dolstra5-21/+54
2011-12-25 * Make sure that lock files are cleaned up properly when buildingEelco Dolstra1-7/+7
through the build hook.
2011-12-22 * Oops.Eelco Dolstra1-1/+1
2011-12-22 * In the garbage collector, delete invalid paths before deletingEelco Dolstra3-12/+45
unreachable paths. This matters when using --max-freed etc.: unreachable paths could become reachable again, so it's nicer to keep them if there is "real" garbage to be deleted. Also, don't use readDirectory() but read the Nix store and delete invalid paths in parallel. This reduces GC latency on very large Nix stores.
2011-12-22 * Drop unnecessary call to canonPath() (nixStore is already canonical).Eelco Dolstra1-1/+1
2011-12-21 * Another case of lock file permissions being too liberal.Eelco Dolstra1-1/+1
2011-12-21 * The ‘foo.drvPath’ feature was already broken in read-only mode.Eelco Dolstra1-1/+2
Since it's rarely used and fixing it is too much work right now, just document it.
2011-12-21 Revert previous commitShea Levy1-9/+0
It doesn't detect indirect references
2011-12-21 Detect and reject mutually-referential outputsShea Levy1-0/+9
There is probably a more efficient way to do this.
2011-12-21 * Simplify the context handling logic.Eelco Dolstra1-24/+13
2011-12-20 * Fix the build.Eelco Dolstra2-2/+2
2011-12-16 * Sync with the trunk.Eelco Dolstra26-275/+461
2011-12-16 * importPath() -> importPaths(). Because of buffering of the inputEelco Dolstra10-57/+75
stream it's now necessary for the daemon to process the entire sequence of exported paths, rather than letting the client do it.
2011-12-16 * Avoid expensive conversions from char arrays to STL strings.Eelco Dolstra3-13/+25
2011-12-16 * Make the import operation through the daemon much more efficientEelco Dolstra6-44/+68
(way fewer roundtrips) by allowing the client to send data in bigger chunks. * Some refactoring.
2011-12-16 * Clean up exception handling.Eelco Dolstra2-3/+10
2011-12-15 * Refactoring: move sink/source buffering into separate classes.Eelco Dolstra8-90/+125
* Buffer the HashSink. This speeds up hashing a bit because it prevents lots of calls to the hash update functions (e.g. nix-hash went from 9.3s to 8.7s of user time on the closure of my /var/run/current-system).
2011-12-15 * Buffer reads in FdSource. Together with write buffering, thisEelco Dolstra2-10/+32
significantly cuts down the number of syscalls (e.g., for "nix-store -qR /var/run/current-system" via the daemon, it reduced the number of syscalls in the client from 29134 to 4766 and in the daemon from 44266 to 20666).
2011-12-14 * Buffer writes in FdSink. This significantly reduces the number ofEelco Dolstra4-14/+50
system calls / context switches when dumping a NAR and in the worker protocol.
2011-12-14 * Remove the terminate handler, which was only really needed becauseEelco Dolstra1-23/+0
of Berkeley DB (see r8632).
2011-12-05 * Remove unnecessary quotes. showPaths() already adds quotes.Eelco Dolstra1-1/+1
2011-12-02 * In ‘nix-store --verify --check-contents’, repair missing hashesEelco Dolstra1-4/+20
rather than complain about them.
2011-12-02 * Move parseHash16or32 into libutil, and use in nix-hash.Eelco Dolstra5-22/+23
2011-12-01 * Allow '<nixexpr>' syntax to be used in nix-instantiate, nix-buildEelco Dolstra4-3/+15
and nix-env, e.g., $ nix-env -f '<nixpkgs>' -i patchelf or $ nix-build '<nixos/tests>' -A login.test
2011-12-01 * Slight improvement.Eelco Dolstra1-3/+2
2011-12-01 * When doing "nix-store --add-fixed" without "--recursive" via the NixEelco Dolstra3-6/+16
daemon (which is an error), print a nicer error message than "Connection reset by peer" or "broken pipe". * In the daemon, log errors that occur during request parameter processing.
2011-11-29 * Get rid of some superfluous error messages if a substituter fails.Eelco Dolstra2-16/+7
* Say "fetch" instead of "substitute".
2011-11-23 * Add an API function exportPaths() that provides the functionality ofEelco Dolstra4-6/+19
‘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.)
2011-11-22 * Move initialisation of variables like nixConfDir from libmain toEelco Dolstra5-33/+45
libstore so that the Perl bindings can use it as well. It's vital that the Perl bindings use the configuration file, because otherwise nix-copy-closure will fail with a ‘database locked’ message if the value of ‘use-sqlite-wal’ is changed from the default.
2011-11-21 nix: add /etc/hosts with localhost entry to chroot builds.Rob Vermaas1-0/+3
2011-11-07 * Boldly make SQLite WAL mode the default again. Hopefully theEelco Dolstra1-4/+3
intermittent problems are gone by now. WAL mode is preferrable because it does way fewer fsyncs.
2011-11-06 There's no need to mess with drvPath at allShea Levy1-6/+4
2011-11-06 Fix faulty reversion of my changes to unsafeDiscardOutputDependencyShea Levy1-1/+1
